A lens comprises a shaped gel, irreversibly hardened so that it is not swellable or soluble in liquids found in the region of the eye, formed from the protein aceous material of the lens of an eye of a warm-blooded animal e.g. cows, sheep and pigs. The gel is formed by (i) dehydrating the protein aceous material or (ii) dissolving the proteinaceous material in an aqueous solution of a salt, acid, alkali or urea and treating with halogen or metal ions or subjecting the sol to an electric field. The gel is shaped by swarfing, pressing or moulding in a shaped permeable membrane. The lens is stabilized by treatment with a tanning agent e.g. formaldehyde or hexamethylene tetramine, which in the case of the latter may be added during gel formation.

Abstract: 1299237 Piezo-electric elements NORTH AMERICAN ROCKWELL CORP 24 Nov 1970 [24 Nov 1969] 55914/70 Heading H1E [Also in Division C7] A process for producing an epitaxial deposit of monocrystalline ZnO on a substrate of monocrystalline sapphire comprises heating a ZnO source material such that the ZnO vapour is transported to and epitaxially deposited on the substrate. The ZnO may be formed as a thin film or as a thick layer and the orientation of the ZnO single crystal is determined by the lattice orientation on the substrate deposition surface. The orientation of the C-axis can thus be varied over a wide range by varying the sapphire cut. Palladium-purified hydrogen at one atmosphere pressure is allowed to flow through a previously evacuated enclosure and powdered ZnO is heated in a quartz boat to a temperature of about 825‹ C., the boat supporting at a distance of 0À5 to 2À0 cm. above the ZnO the inverted substrate which is heated to a temperature of about 775‹ C. HCl gas may be introduced into the enclosure in a preferred concentration of about 2% of the total gas to clean the substrate before deposition. In a directional transducer in which the C-axis is parallel to the plane of the substrate, gold or aluminium electrodes may be evaporated on to the ZnO surface.

Abstract: 1,248,065. Gauging apparatus. BENDIX CORP. 4 Dec., 1968 [12 Dec., 1967], No. 57620/68. Heading G4H. [Also in Division G1] To determine deviations in the required dimension of a member 1, as the member moves along one axis X, the nominal dimension in the Z direction is compared with a signal 20 representing the position of a carriage 12 carrying a transducer 8 sensing the surface of the member and the error signal is added to a signal 11 representing the position of the transducer 8 relative to the carriage 12, the combined signals which represent the deviation being recorded. In the embodiment described the transducer 8 includes a differential transformer arrangement in which a stylus 10 sensing the surface positions an armature. The output signal from the transducer is fed to a servo amplifier 31 controlling a motor 14 which moves the carriage 12 to reduce the error signal and simultaneously drives an encoder 18 delivering the digital signal 20. A motor 3 moving the member 1 along the X axis also drives encoder 5, the signals from which are fed to input logic and interpolator 23 which delivers in digital form the nominal Z dimension of the object for that position to error register 24. The digital error between the carriage position and the nominal dimension is converted to analogue form before being added to the output signal from transducer 8. By the use of suitable circuit converters the electrical signals may be analogue or digital or combinations of both.

Each side of disc 1 has a respective spiral record track defining arcuate signal areas 5, Fig. 3, of low reflection separated by high reflection areas, areas 5 having constant width 5a of about 5 microns variable spacing 5c, variable length 5b of at least 2 to 3 microns, with the spacing 5d being about 2 microns. Light from a fixed source 8, e.g. a laser, is reflected via mirrors 10, 11, Fig. 4, into reproducing device 12 moved radially inwards by a motor 19. The light beam entering device 12 is split by a mirror 17, Fig. 5, into a main beam 28, forming read spot 30 and being reflected 22 into a photo-detector 24, and an auxiliary beam 29 passing via a condenser 18 to form an auxiliary spot 31 and a reflected beam 23 directed to photo-detector 25. The deflector 15 may be a moving coil device rotating a mirror or prism Fig. 12 (not shown). The output of detector 25 is processed to form a control signal applied to a driver 62 which moves the parts of device 12 in the chain-dot line in Fig. 5 to correct for disc eccentricity. Alternatively, driver 62 only moves the condenser 14. Vertical movement of disc 1 relative to device 12 is detected as a change in capacitance between disc 1 and an adjacent plate to produce a control signal causing focusing means 16 to move condenser 14 vertically to maintain spot 30 focused on the disc (1), Fig. 22 (not shown).
