Abstract: With a high minus powered anterior surface toric lens with a prism ballast there is a difficulty in maintaining stability of the lens. In this invention a contact lens particularly a high minus powered anterior surface toric lens is made having a toric central optical portion (1) without prism and an annular outer portion (3) having prism but without toric effect, the outer portion being truncated in a lower part (5) so that there is upward movement of the centre of rotation (9) of the blank and of the centre of gravity (8) in a manner such that the centre of gravity is in use below the centre of rotation, thus assisting if the lens is rotated by lid or eye movement the lens tends to rotate back into correct orientation.

Abstract: A device for connecting a hydraulic pump or other pressure fluid source to a working cylinder or other fluid motor comprises a pair of concentric hoses and a safety shut-off valve. One end of the inner hose is connected to the cylinder and the other end is connected to the pump by way of the safety shut-off valve. The space between the hoses normally is unpressurized and is in constant communication with a cavity containing a movable element of the shut-off valve. An elevated pressure in the space between the hoses will actuate the valve element for closing the shut-off valve. A second valve element is movable to close the valve when subjected to fluid flow forces resulting from an excessive flow of hydraulic liquid through the shut-off valve.

Abstract: A transducer for convening an AC voltage to a DC voltage to obtain a DC output voltage which is in response to an AC input voltage. An AC input voltage (e11) representing conditions of an AC power system is rectified through a full-wave or half-wave rectifier (12) of the transducer to thereby provide two kinds of DC voltages (e12, e14), each of which is in proportion to the AC input voltage (e11) and has a ripple component. These two kinds of DC voltages (e12, e14) are then compared with each other at a comparator and there is provided a DC output which corresponds to the smaller one of the DC voltages. This transducer is available for signal sources for data loggers, digital computers, telemeters and the like.

Abstract: In order to shorten the length of a cylinder lock compared with conventional locks in which the tumblers are all moved by a single control track running along the length of the key, the control surfaces of the tumblers (4, 5, 9, 10, 11, 12, 13, 14) are arranged in tracks which are in side-by-side relationship for engagement by a key having control surfaces (27 - 30) running along the length of the key in a corresponding side-by- side arrangement across the width of the key so that several control tracks operate simultaneously on the tumblers as the key is inserted. Both half-plate tumblers (4, 5, 11, 12, Figure 7, not shown), and frame tumblers 9, 10, 13, 14, Figure 6, also not shown), are employed.

Abstract: A plastic material, preferably polyvinylidene fluoride (PVDF) film, made highly piezoelectric by known methods, is placed in a sensor unit structure wherein pressure is exerted against the piezoelectric film by means of rotation of the steering wheel of the boat or vehicle to thereby cause the piezoelectric film to generate electric signals which are used in controlling the rpm of a low-inertia, instantaneously reversible steering power assist motor. The rpm of the motor is substantially proportional to the electric signals, which, in turn, are determined by, and responsive to, the degrees of rotation and speed of rotation of the steering wheel. The direction of rotation of the steering wheel determines the direction of steering assist, i.e., to the left or right. Available torque of the motor however is substantially inversely proportional to rpm of the engine propelling the boat or vehicle.

Abstract: A flotation machine consists of a flotation chamber and a rotating gas diffuser. The flotation chamber has a lower mixing chamber and an upper quiescent zone for maximizing float accumulation. The rotating diffuser produces ultra fine bubbles as small as 50 microns in diameter. The size of the bubble diameter can be controlled and produced in any size from less than 50 microns to greater than 10 mm to enable flotation of various materials and/or various sized fractions of materials. The ultra fine bubbles are produced by the diffuser in the same size range as bubbles produced by dissolved air flotation, but without the necessity of pressurizing gas in a first tank followed by depressurizing in a second tank. Since the diffuser is located within the flotation chamber and can vary bubble size, it also provides the advantage of sparged air flotation. This rotating diffuser configuration is a low drag thin disc and, when combined with a specially designed flotation chamber, embodies a flotation machine which produces higher product yields over a wider range of feed size fractions utilizing significantly less energy.

Abstract: The method for manufacturing metal fibres from spherical particles (6) of a metal powder provides for feeding the spherical particles (6) of the metal powder to a main roll (2) and a supplementary roll (3) of a deforming tool (1) so that each of the spherical particles (6) is transferred in the direction of technological processing, deformed by rolling and is simultaneously extended along a rotation axis thereof. The extension of the particles is effected through a means, being the supplementary roll (3), at a rate which is higher than the rate of a free flow of the metal into an extension zone, which flow might occur whilst the diameter of the deformed spherical particle is reduced by said supplementary roll. Then the metal fibres are unloaded.

Abstract: A process and apparatus for delivering carbon i.e., coal dust, to be combusted in a furnace is presented. The furnace is of the type having plural combustion points and may include a shaft furnace such as, for example, a blast or cupola furnace. The carbon dust is delivered in dosed quantities to each of the individual combustion points in a separate air stream which is under a predetermined pressure. The carbon (coal dust)/carrier gas (air) is delivered to each combustion point in the furnace at super critical speed, i.e., the speed of sound, the carrier gas having a relatively high proportion of solid material therein. The actual quantity of carbon material delivered to each combustion point is directly detected and monitored as a consequence of volumetric measurement and is appropriately corrected by means of a secondary air supply when the carbon quantity either exceeds or falls below a predetermined nominal value. The apparatus of the present invention includes plural conveyor lines being connected at one end thereof to a particular combustion point. The end of the conveyor line which is connected to the combustion point comprises a nozzle which delivers the carbon/carrier gas stream at a super critical outflow speed. The diameter of the nozzle and the predetermined pressure prevailing in the conveyor line is a function of the preselected nominal quantity of carbon which is to be delivered to the furnace.

Abstract: In a method for measuring ink density of printed sheets by means of photodiodes which scan light reflection from measuring marks provided on printed sheets, the start of a dynamic measuring process during the running of the printing machine is released by the control of impulse flanks, and the reflected light is scanned by sensors having a short response time. A medium reflection value of the surface of the measuring mark is determined. The control of impulse flanks takes place by a leading edge of the mark printed on the sheet, and the signal, released by that control, switches on the photodiodes and the light source. A changed voltage occurring at the output of each photodiode is amplified, and its peak value is stored; and the photodiodes and the light source are switched off thereafter.
