Title: Synchronization recovery in a communications system
Inventor: VAN RASSEL WILLIAM F
IPC: H04L7/04
Filed: 1986-02-20
Granted: 1991-09-03
Abstract: SYNCHRONIZATION RECOVERY IN A COMMUNICATIONS SYSTEM          ABSTRACT OF THE DISCLOSURE        Synchronization between a transmitter and a receiver is effected by encoding and transmitting a synchronization pulse as a series of m first waveforms followed by a series of n second waveforms. The first and second waveforms are of the same duration and are trans-mitted in phase with each other; and m and n are positive real num-bers, with m greater than one. The second waveform is different from, and preferably negatively correlated with, the first. When the receiver detects a series of first waveforms in the received signal, it locally generates a series of (either first or second) waveforms and correlates the locally-generated signal with the received signal. A change in cor-relation is detected as the synchronization pulse.

Abstract: ABSTRACT OF THE DISCLOSURE         Each of coupling elements mounted on a slide fastener stringer tape has a coupling head and two legs extending from the coupling head and mounted astride of a longitudinal beaded edge of the stringer tape, the legs being integrally interconnected by a connector extending through the stringer tape.  The coupling elements are removed from the stringer tape by gripping the stringer tape between a pair of grippers with the coupling elements supported on the grippers, thrusting cutting edges into the coupling head of each coupling element toward the longitudinal beaded edge to break the coupling head, and driving wedge-shaped spreaders into each coupling element through the broken coupling head thereof to spread each coupling element until the connector is forcibly broken, for thereby breaking each coupling element into two pieces off the stringer tape.

Abstract: A non-tacky, solid, adhesive composition comprising:   (a) at least one film forming polymeric resin of number average molecular weight (Mn) of at least about 10,000 and having a hydroxyl, epoxide or unsaturated functionality greater than about 7, the polymeric resin being selected from the group of polyols consisting of polyesters, polyurethanes, phenoxies, epoxies and mixtures thereof; a plasticizer present in an amount which permits the activation without C-staging of the polymeric resin; (b) a curing agent which is capable of crosslinking and curing the polymeric resin to a C-stage, the curing agent being present in an amount sufficient to C-stage the polymeric resin.  The adhesive composition can be activated without C-staging the polymeric resin, upon application of sufficient heat or ultrasonic energy for a time period less than one second.  The curing agent is non-reactive at the conditions which will activate the adhesive composition, but can be made reactive upon application of sufficient energy in the form of radiant energy or in the form of heat above the activation temperature, for a time period sufficient to cure the polymeric resin in the composition.  The adhesive composition is capable of converting, in the C-stage, into an infusible composition which does not melt, flow or decompose when exposed for 10 seconds to molten solder at 260°C and does not soften when exposed to dichloroethane at 25°C for 10 seconds;  The adhesive composition is suitable for forming a wire scribed circuit board and embedding a wire conductor on a surface of the circuit board.

Title: Optical beam splitter prism
Inventor: BUHRER CARL F
IPC: G02B27/28
Filed: 1986-10-07
Granted: 1991-06-18
Abstract: OPTICAL BEAM SPLITTER PRISM            ABSTRACT:      An improved geometry for an optical beam splitter prism permits all input and output beams to be parallel and to remain parallel while the prism is misaligned.  It is particularly useful in conjunction with fiber optic couplers and is applicable to splitting with respect to light intensity, polarization or wavelength.  This can be achieved through the construction of a beam splitting prism having an additional reflecting surface on one input beam and on one output beam, whereby each of these surfaces are parallel to the beam splitting surface and with two parallel input and output surfaces through which all beams pass so as to make all input and output beams parallel and remain parallel as the prism is translation-ally or rotationally misaligned about any axis.

Abstract: ABSTRACT OF THE DISCLOSURE         A light receiving member comprises a support and a light receiving layer having a photosensitive layer composed of a-Si(Ge,Sn)(H,X) or a-Si(Ge,Sn)(O,C,N)(H,X) and a surface layer composed of A-Si(O,C,N)(H,X), said support having a surface provided with irregularities composed of spherical dimples,  each of which has an inside face provided with minute irregularities.  The optical band gap possessed by the surface layer and the optical band gap possessed by the photosensitive layer on which the surface layer is disposed are matched at their interface.  The light receiving member can  effectively  prevent  the  occurrence  of  interference fringes in the formed images.   In addition,  the light-receiving member forms visible images of excellent quality even when coherent laser beams are used as the light source.          The member also effectively prevents reflection of incident light at the interface between the surface layer and the photosensitive layer.

Granted: 1991-10-08
Abstract: ABSTRACT OF THE DISCLOSURE    Edible fats and oils are extracted from oil-bearing materials by loading the raw materials onto an inlet end of a flat and fixed conveying surface having elongate slits therein.  The materials are conveyed from the inlet end to the outlet end of the conveying surface by scrapers moved by endless chains.  Oil extracting solvent is sprayed onto the material on the conveying surface, to produce miscella, which flows through the slits in the surface and into hoppers beneath the surface.  The miscella is circulated back to additional sprayers located upstream of the solvent sprayers for spraying the miscella onto the upstream end of the conveying surface.  The resulting concentrated miscella is collected in hoppers beneath the surface and delivered to a further use.

Title: Video special effects apparatus
Inventor: CHAPLIN DANIEL J
IPC: H04N5/265
Filed: 1988-03-24
Granted: 1993-04-27
Abstract: Abstract Video effects apparatus comprises a pattern generator for generating a mix control signal which, when used to control the combination of first and second input video signals to provide an output video signal, defines the geometrical shape in a composite output scene of a transition between a first component scene represented by the first input video signal and a second component scene represented by the second video signal.  The pat-tern generator responds to a size control signal by causing the mix control signal to vary in a manner such that the area of the composite output video scene that is occupied by the first component scene changes relative to the area of the second compo-nent scene while the geometrical shape of the tran-sition between the component scenes remains the same.  A shadow generator generates a signal which adjusts the visual characteristics of the second component scene synchronously with the variation of the control signal.
