Abstract: ABSTRACT OF THE DISCLOSURE         An optical information reproducing apparatus for reproducing an information recorded on a recording sur-face of a disc shape record medium is disclosed, which includes an optical pick-up device mounted on a tiltable optical block and having a laser beam source for generating a laser beam and a photo detector for detecting the reflected beam from the recording surface and for reproducing the recorded information, a device for rotating the record medium, a skew error detector for detecting a skew of the record medium relative to the optical pick-up device and for generat-ing a skew error signal having a D.C. component and an A.C. component, a control circuit supplied with the skew error signal and for generating a control signal responsive to the D.C. component of the skew error signal, a skew error corrector controlled by the control signal and for controlling the optical block so that the optical axis of the pick up device is maintained to be always perpendicular to the recording surface.  The above control circuit includes a comparator for comparing the level of the skew error signal with a threshold level and for generating an output pulse, the width of which corresponds to the D.C. component of the skew error signal, and a pulse width discriminator for discriminating the width of the output pulse relative to a reference pulse corresponding to a rotating period of the record medium.

Abstract: ABSTRACT OF THE DISCLOSURE    A control device to remotely engage and disengage a clutch having a manually operable lever, consisting of a link pivoted to the lever and to a sector plate.  The latter is pivotally mounted on abase and is adapted for movement with a swing arm mounted on the same pivot and extending radially of the sector plate.  The swing arm carries a slidable dog releasably engaged with the sector plate and is moved by a power-operated lifter.  The sector plate is connected to the link and is adapted to move between a first declutched position, and a second clutched position, and a final operative position intermediate the two first-named positions, nearer the second position, thereby prevent-ing undue stress on the bearings of the clutch actuation assembly when the clutch is operative.

Abstract: ABSTRACT OF DISCLOSURE      Conforming a three-dimensionally patterned layer of porous material directly on a base member made of plastic, metal, glass, etc., and then applying a coating of a hard-enable film-forming liquid in an amount just sufficient to cover the "hills" of the patterned material and seal its pores, but not to fill the "valleys" of the material when hardened.  As a result, contours of the pattern are not obscured.  The desired pattern may be the inherent weave (interlaced threads) of a textile or an ornamental design embossed in a non-woven material, or the like.  Penetra-tion of the film-forming liquid through the pores and into the interface between the fabric and base member partially adheres the fabric to that member upon application of the liquid, an adherence only completed upon hardening, so that interim adjustment in positioning is provided.

Abstract: Abstract:      An elastic surface wave device comprises a piezo-electric substrate, a first transducer group, and a second transducer group or groups located on one or both sides of the first group to exchange elastic surface waves with the first group.  The second group comprises a plurality of transducers sharing the same elastic surface wave propagation path.  The geometrically central positions of the individual transducers making up the second group are located symmetrically about the geometrically central position of the entire second group, with each pair of such symmetrically located transducers incorporating the same number of pairs.  The delay time taken by elastic surface waves propagating between the centers of every two adjoin-ing transducers, excluding the two outermost transducers, is constant.  The distance between the center of each of the two outermost transducers and that of the transducer adjoining the outermost transducer is so determined that the delay time taken between the two transducers is, if the number of pairs incorporated in the outermost trans-ducer is an integer, equal to an odd-number multiple of one half of the constant delay time, or, if the number of pairs incorporated in the outermost transducer is not an integer, equal to an odd-number multiple of one half of the constant delay time plus or minus a quarter wavelength time.  The result is a device the design of which is relatively simple and which enables stop-band response signal rejection and pass-band characteristic improvement for loss reduction, radiation conductance control on the transducers and arbitrary bandwidth setting.

Abstract: An apparatus and process for spraying liquids wherein means are provided for subjecting liquid emerging from the sprayhead to an electrical field sufficiently high for the liquid to be drawn from the sprayhead in the form of one or more filaments.  The filament or filaments become unstable and subsequently break up into droplets.  A stream of gas is caused to flow through the region of the high electrical field, the gas flowing in a direction parallel or substantially parallel with the direction in which the liquid emerges from the sprayhead.  Droplets are thus removed from the region and a build-up in space charge is reduced.

Abstract: ABSTRACT             A gastrointestinal sphincter to be surgically implanted around a lumen (e.g. bowel) of a patient to apply variable occlusive pressures for articulating the lumen.  The sphincter includes a continence producing occlusion cuff (1) having a hollow, expansible chamber (2) formed therein to embrace the lumen.  Communicating in a single, continuous fluid circuit with the expansible chamber are first (6) and second (32) fluid circuits having respective first and second reservoir supplies of fluid (30 and 46) located therein.  Each of the reservoir supplies may be selectively actuated in order that fluid will be delivered to the expansible chamber to controllably expand the chamber and thereby produce variable occlusive pressure levels for achieving continence. A fluid filled physician control port (24) is interconnected with one of the fluid circuits (6) and surgically implanted so as to be accessible to a fluid filled syringe.  A carefully controlled volume of fluid from the port can be delivered to the expansible chamber via the associated fluid path to generate the minimum increased occlusive pressure necessary to achieve coaptive continence according to the tissue requirements of the patient.     The occlusion cuff also has a relatively extensible membrane (56) that is subject to variable elongation in response to at least a predetermined minimum tensile stretching force.  The membrane is interconnected with the occlusion cuff to increase the circumference of the cuff around the patient's lumen to thereby accommodate possible distention of the lumen.
