I never owned any of the big British marques but I had plenty of bikes almost all German,in those cash strapped analogue days we spent far too much time opening up engine cases and renewing spent bearings. This followed the traditions of the "cafe racers" who we pathetically attempted to emulate whilst the lamentable electrics really made the most passionate patriot question the ability of an industry set in a wet northern climate that produced timing mechanisms that required constant attention. I borrowed my brother in laws C90 Honda step through to ride from Wadebridge to Truro through torrents of rain, on my return I realised that allowing ones prejudices to influence vital transport choices was one hell of a mistake.

Thats a better interpretation than mine, it just seems devoid of any redeeming features - man made, natural or supernatural.

One good cottage deserves another.

No I didn't check, though I do remember what you're talking about. Thick and greasy. That isn't a one off either. Malta is covered in red boxes, and they drive on the left, the public signage is in English, and the electrical outlets are Uk 3 square pin - etc. etc. As a Brit coming from Spain it does feel a bit weird for the first few days. Like a bit of Tunbridge Wells crossed with Beirut dropped into the middle of the Med.

I'm surprised this is still standing, even though it's listed. There have been a lot of "Listed" buildings in Newham that have been demolished in the dname of progress. But no one seems bothered.........

"state that they hold certain isles in the sea between Cornwall and Ireland, of which the largest is called Scilly, to which ships come passing between France, Bretagne, Galithia, Bayonne, Gascony, Scotland, Ireland, Wales and Cornwall:

and, because they feel that in the event of a war breaking out between the kings of cELTIC bRITAIAN and France, or between any of the other places mentioned, they would not have enough power to do justice to these sailors, they ask that they might exchange these islands for lands in Devon, saving the churches on the islands appropriated to them."

Meniscus Systems

a variety of optical catadioptric systems in which a spherical (or, less frequently, an elliptical) mirror, or a system of mirrors and lenses, is preceded by one or more achromatic menisci. Meniscus systems were invented in 1941 simultaneously and independently by D. D. Maksutov and D. Gáabor. Meniscus systems use meniscus lenses with surfaces that have nearly the same radii of curvature. Lenses of this type are compensators; that is, they have little effect on the general direction of the rays but appreciably change the distortions (aberrations) of optical images of the optical systems of which they are a part.

A meniscus is nearly achromatic (that is, it is free from chromatic aberration) with respect to a parallel pencil of rays if the

quantity (R1 — R2)/d is close to 0.6, where R1 and R2. are the radii of curvature of the meniscus surfaces and d is the thickness of the meniscus (see Figure 1 ,a and b). At the same time, R1 and R2 may be selected such that the negative spherical aberration of the mirror (mirrors) is compensated by the positive spherical aberration of the meniscus. The coma in a meniscus system depends on the distance between the meniscus and the mirror, and at a certain position of the meniscus the coma is equal to zero. The astigmatism of the simplest meniscus systems is low. The curvature of the image field in a meniscus system is significant. For this reason, photography in these systems is performed on appropriately curved photographic film. However, the use of an additional corrective Piazzi-Smyth lens, which corrects the curvature of the field as well as the distortion, makes it possible to perform photography using meniscus systems on flat plates and films. Single-meniscus systems with high aperture ratios exhibit low chromatic aberration, which is known as chromatism of magnification. This effect is eliminated by using a pair of oppositely oriented menisci (Figure 2,a, b, and c). The same goal is attained in other cases by a light retouching of one of the surfaces of the

Practical applications in astronomy include meniscus systems in telescopes (which are also called Maksutov telescopes), schematically represented in Figure 3. The first scheme (Figure 3,a) provides adequate field of view (up to 5°) and aperture ratio (up to 1:1.2). The second scheme (Figure 3, b), which is the meniscus analog of the Cassegrain reflector system, provides a moderately large field of view (of the order of 1°) at a long focal length and, therefore, at a lower aperture ratio (1:10 to 1:15). The third scheme (Figure 3,c), which is the meniscus analog of a Gregorian reflector system (telescope), resembles the second scheme in its features.

Cassegrain-type meniscus systems are used in photographic objectives of long focal length. The shortness of these objectives for a relatively large diameter of the entrance pupil gives them an important advantage over telephoto lenses.

Meniscus systems are more compact than other optical systems with comparable parameters, which simplifies the control of meniscus telescopes by clockworks. Their principal surfaces are of a simple form (spherical), which simplifies manufacture and permits precise optical control of the meniscus systems. Correction of all the principal aberrations leads to high-quality images not only in the center of the field of view but also at the edges of large fields of view

The long blue days, for his head, for his side, and the little paths for his feet, and all the brightness to touch and gather. Through the grass the little mosspaths, bony with old roots, and the trees sticking up, and the flowers sticking up, and the fruit hanging down, and the white exhausted butterflies, and the birds never the same darting all day long into hiding. And all the sounds, meaning nothing. Then at night rest in the quiet house, there are no roads, no streets any more, you lie down by a window opening on refuge, the little sounds come that demand nothing, ordain nothing, explain nothing, propound nothing, and the short necessary night is soon ended, and the sky blue again all over the secret places where nobody ever comes, the secret places never the same, but always simple and indifferent, always mere places, sites of a stirring beyond coming and going, of a being so light and free that it is as the being of nothing.

The term "Archeometre" originates from the Greek and means "the measure of the principle". The system refers also to a series of symbols and meanings, which refer to the federal drawer.

'Archeometre' is it the measurement of the 'Archee' (Universal Cosmic Force) of which the Hermetists speaks. Is it a process, a 'key' which makes it possible to penetrate the Mysteries of the Word. It is a measuring instrument of the first (primary) principles of the manifested universe.

Alexandre Saint Yves d'Alveydre's Archeometre shows the original Atlantean alphabet translates into the material the word, form, color, smell, sound and taste, the key to all religions and the sciences of antiquity.

The Archeometre is represented by a circle, which has two scales from 0 to 360 degrees and 360 degrees to 0. It is divided into 12 ranges with 30 degrees each. In the individual ranges are drawn in the tierkreiszeichen, planet, colors, tones and the letters of different alphabets.

The Archeometre is a universal canon (guide), which wants to point the relationship out between the astrological indications, tones, smells, letters and colors. The musician finds therein the color of tones, the writer the toncharakter of letter etc. The Archeometre is to also point practical use out that the religions, arts and architecture a synthesis from different ranges to form.
