Abstract: ABSTRACT OF THE DISCLOSURE          A hydrophilic silicone contact lens can be produced by pouring into a mold a silicone resin monomer, heating the monomer to effect polymerization, processing the resulting formed product into a lens, and then irradiating the surface of the lens with a low temperature gas plasma to impart hydrophilic pro-perty to the surface of the lens.  Further, in order that the hydrophilic property can be maintained for a long period of time even if the lens is allowed to stand in the air, a hydrophilic resin film may be formed on the thus irradiated surface of the lens.

Granted: 1979-12-04
Abstract: ABSTRACT OF THE DISCLOSURE       A clutch having a simple adjustment mechanism permitting adjustment of the gap between the clutch elements, without dis-assembling the clutch.  The preferred clutch includes camming rings which are spread upon actuation of the clutch to engage the clutch elements and compress the clutch spring.  The adjust-ment mechanism includes a nut threadably received on the driven shaft, a cup-shaped slide received on the nut and biased against the camming rings by the clutch spring.  During clutching, the slide is moved axially relative to the shaft by spreading the camming rings, compressing the clutch elements and biasing the spring.  The clutch is adjusted by axially threading the nut on the shaft, biasing the slide against the camming rings and reduc-ing the gap between the clutch elements.

Abstract: ABSTRACT OF THE DISCLOSURE            A connector-cable assembly in which a flat, multiple wire cable is secured in a connector body through a transverse, sharply angled rib, and the stripped wire ends are terminated into a plurality of plate members disposed in parallel planes and spaced longitudinally of the wires to provide mounting and working space.    Each wire is terminated by being progressively urged and then forced into an open throated slot formed in one of the plate members.  The slots are formed so that there is intimate, large area contact, and wedge resistance to linear pull-out.  The plate members are plated for corrosion resistance and a heating step following mechanical connection causes melting or intermetallic diffusion.          The rib not only provides strain relief, but also indexes the cable end for assembly and anchors the cable for partial stripping -- the latter permitting simultaneous and convenient positioning of the wires.

Abstract: AN OPTICAL SYSTEM FOR RECORDING AND READING     AN INFORMATION ON A TAPE.                Abstract of the Disclosure An optical system for recording n information signals on a photosensitive tape in the form of a discontinuous track made up of parallel track sections by means of n light beams having a two states modulated intensity, being simultaneously deflected by an acousto-optical deflector and focusing on the tape in the form of n equidistant spots aligned in a direction x. The combination of the deflection and a translation movement of the tape produces a scanning movement of said n spots in a direction perpendicular to x. The same system is made for the reading of the information transcribed on the tape, the beams being then not modulated, by means of photodetector means which receive the light emerging from the tape and provide information signals in relation with the physical modifications obtained on the tape during the recording.

Title: Load actuating servomechanism with  resonance equalization
Inventor: BIGLEY WILLIAM J
IPC: H02P23/00
Filed: 1978-05-30
Granted: 1982-06-01
Abstract: ABSTRACT Load actuating servomechanism apparatus includes dynamic regeneration to equalize and overcome a frequency-varying load/load drive train mechanical resonance.  The drive circuitry comprises a per se conventional primary motor speed controlling rate feedback loop including a cascaded rate signal command source, summing error-signal producing node, and loop frequency response shaping filter and driver amplifier for exciting a load driving motor, and a rate tachometer signal feedback element connecting a measure of the motor output speed to a subtractive input of the summing node.     To broaden the response band of the primary feedback circuit and accommodate a mechanical resonance otherwise interfering therewith, a secondary, positive feedback path supplements the input rate command with a signal dependent upon motor current, and thus upon motor load.  Accordingly, output load drive automatically increases as motor current increases when a load drive retarding mechanical resonance is encountered.

Abstract: ABSTRACT OF THE DISCLOSURE         Tubular filter elements are formed by first feeding a dispersion of fibres in liquid into a tubular moulding space between a vertical core and a cylindrical fine mesh screen.       Air pressure is applied to the ispersion so that the liquid drains through the screen and through a screen at one base of the space, while a mass of microfibres builds up to be removed from the space for bonding by a synthetic resin.  A reciprocable sleeve increases the effective height of the screen as the mass builds up.  The process packs the fibres in the circumferential direction more uniformly than is possible with prior techniques providing high filtering efficiency and a capacity to withstand high differential pressures.
