IPC: D02J1/22
Filed: 1993-10-01
Abstract: Abstract Core yarns with a core of high strength polyester materi-al,  production thereof and use of selected polyester materials for producing core yarns There are described core yarns with selected filamentary polyester cores.  In the core yarns, a) the polyester material of the core filaments has an average molecular weight corresponding to a relative solution viscosity (determined on solutions of 1 g of polyester in 100 ml of dichloroacetic acid at 25°C) of at least 1.9, and b) the core has a specific strength of at least 60 cN/tex, the core yarns producing a seam length to rupture of more than 800 cm in a sewing test under aggravated conditions, said sewing test being carried out on four plies of cotton twill of basis weight 350 g/m2 with 5000 stitch-es/min, four stitches/cm, a sewing tension of 220 cN and with sewing in the forward direction.            The core yarns are obtainable by a process comprising the measures of: i) producing multifilament yarns based on polyesters having an average molecular weight correspond-ing to a relative solution viscosity  (determined on solutions of 1 g of polyester in 100 ml of dichloroacetic acid at 25°C) of at least 1.9 by melt spinning polyester with a takeoff speed of at least 1500 m/min, preferably from 1900 to 3200 m/min, and subsequently drawing under conditions such that the yarn has a breaking extension of about 15% and a breaking strength which corresponds to the maximum breaking strength obtainable for the yarn in question or is up to 30% below that value, and ii)  sheathing this multifilament yarn with fibers of vegetable, regenerated or synthetic origin or mixtures thereof in a conventional manner in such a way that the multifilament yarn is virtually completely covered.

Abstract: MAGNETICALLY RELEASABLE CLAMP     ABSTRACT OF THE DISCLOSURE   A clamp includes a U-shaped member having a pair of legs, with each leg having a cavity in the side of the leg facing the other leg; and a clutch for receiving and restraining the legs of the U-shaped member. Pads are attached to the insides of the legs for clamping an article between the legs to deter thetheft of such article. The clutch includes a housing defining a pair of lon-gitudinal channels for respectively receiving the legs of the U-shaped member and a chamber between the channels, with the chamber being open to the channels; two balls disposed for movement within the chamber; a highly mag-netically attractive plunger disposed within and at one end of the chamber; and a spring for biasing the plunger to move into such contact with the balls as to force the balls against respective inclined surfaces disposed at the other end of the chamber for respectively guiding the balls toward different channels. When the legs of the U-shaped member are inserted into the channels so that the cavities are respectively adjacent the balls while the plunger is forcing the balls against the inclined surfaces, the inclined surfaces guide the balls respectively into the cavities and into contact with portions of the respective legs adjacentthe respective cavities to thereby restrain the legs of the U-shaped member in the housing. To release the legs from the clutch, a magnet is placed adjacent the one end of the housing to magnetically attract the plunger and the balls toward the one end of the chamber and thereby release each ball from a locked position between the respective inclined surface and the portion of the leg thatcontacts the ball.

Inventor: BARCLAY MICHAEL J
IPC: H03B1/00
Filed: 1994-06-01
Abstract: A voltage controlled oscillator apparatus for generating a desired frequency, set by a tuning voltage, toward modulating a transmission signal on the desired frequency. The voltage controlled oscillator apparatus includes an oscillator transistor the base of which is RF live so as to destabilize the transistor such that it oscillates. The oscillator transmitter emitter is operably connected through a capacitor to a tank circuit, which stores RF energy at the desired frequency, based on the tuning voltage, to set the oscillator transistor frequency. The inherent collector-base junction capacitance serves to provide voltage variable capacitance resulting in the generation of a carrier signal. The oscillator transistor collector is electrically connected to an amplifier transistor's emitter, such that the amplifier transistor and oscillator transistor are in cascode configuration.      The amplifier transistor amplifies the transmission signal input at its base and presents a signal output on its collector. whereby the need for a varactor external to the tank circuit is alleviated and the transmission signal is amplified and modulated on the carrier signal by the amplifier transistor due the interconnection between the oscillator and amplifier transistors in a manner which effectively isolates the transmission signal from the oscillator transistor and tank circuit.

Title: System of relational entities for object-oriented computer-aided geometric design
Inventor: LETCHER JOHN S JR
IPC: G06T19/00
Filed: 1992-12-17
Abstract: Geometric objects including points, lines, curves, surfaces and solids are defined and constructed in a system which retains and utilizes relationships and dependencies between objects in a directed graph (digraph) data structure. The primary advantage is automatic updating of the model, preserving dependencies, when an underlying object is changed. Multiple types of parametric curves and surfaces and multiple levels of dependency are easily supported through a recursive program structure. Difficulties of surface-surface intersection and trimming are largely avoided by provision of novel entities which permit construction of accurate and durable joins between surface objects. An example model of a sailing yacht design illustrates six surface objects of several types with the defined dependency relationships. The hull (271) deck (272), cabin forward (273), cabin side (274), cabin aft (275) and cabin top (276) surfaces intersect at joins (278), (279) which are accurate and durable. The connectivity at the joins and the relative positioning of the surfaces are automatically preserved as the model is updated by changing one of the surfaces.

Abstract: A policing device is proposed in which a plurality of parallel police processors (PP1, PP2) are included each of which implements a Modified Virtual Scheduling Algorithm and is so able to derive for a cell for which it is activated by an enabling circuit (EC) a conformance signals (CS1, CS2). An arbitration module (AM) generates from the latter signals, a plurality of which may be provided per cell of the input ATM stream (IN), a discard signal (DS) indicating wether or not such a cell may be inserted into an output stream (OUT) by a discard circuit (DC) as well as feedback signals (FS1, FS2) which indicate to a corresponding processor whether or not to carry out an already prepared update of a predicted arrival time used in the above mentioned algorithm.          The architecture of the present policing device is very generic in that it allows implementation of any policing method by straightforwardly adapting the arbitration module and the enabling circuit.
