Granted: 1986-01-02
Abstract: 1. System for radio transmission of a binary-coded signal, having circuit means (111, 112, 113) at the transmitting end which convert the signal in a suitable manner and modulate the converted signal upon a radio-frequency signal in any type of modulation suitable for the transmission of analog signals, and having circuit means at the receiving end which demodulate the radio-frequency signal and supply the demodulated signal to a limiter (201) delivering a bipolar signal dependent upon the momentary polarity of the signal applied thereto, characterized by a formation of the said transmitting-end circuit means (111, 112, 113) such that these circuit means convert a binary value of a first kind (0) supplied to them into a single, complete sinusoidal oscillation (Fig. 4) of a first frequency and a binary value of a second king (1) supplied to them into a sequence (211) consisting of an oscillation packet of a second frequency and a single, complete oscillation of the said first frequency, the said second frequency being a multiple in excess of three of the said first frequency, and the said single oscillation having the same shape in all cases, and characterized by a receiving-end series connection consisting of a low-pass filter (202) and a threshold-value detector (203) for converting the output signal (212) emanating from the said limiter (201) into a binary signal (214), the low-pass filter (202) having a critical frequency situated between the said first and second frequencies, and the threshold-value detector (203) suppressing in each case the first semi-oscillation of the said oscillation (213), whereby this series connection delivers a signal (214) consisting of a pulse train, the pulses of which correspond to half an oscillation of the first frequency and the pulse separations of which correspond either to the duration of half an oscillation of the first frequency or to the sum of the duration of an oscillation packet of the second frequency and the duration of half an oscillation of the first frequency.

Title: A process for the continuous partial crystallization and the separation of a liquid mixture and a device for carrying out this process
Inventor: THIJSSEN HENRICUS A C
IPC: B01D9/02
Filed: 1983-01-05
Granted: 1986-12-11
Abstract: Process for continuous crystallization of a liquid mixture in which the mixture is led through a cascade of cooling sections. The temperature in the first section is such that a part of the mixture crystallizes, the temperature in each succeeding section is lower than in the preceding section. The temperature in the last section is such that not the whole of the liquid mixture solidifies. The crystals kept suspended in the liquid are led through the cascade. In one section, not being the last one, the crystal and liquid flow is divided in two flows. One flow mainly formed by the crystals, the other by the liquid. A portion of the divided flow is recycled to the dividing section to keep the crystal volume fraction at a desired value.

Title: Method of producing a thread in a tube or a piston rod made of a composite material
Inventor: DAUGNY DANIEL
IPC: B29C53/56
Filed: 1984-11-15
Granted: 1988-02-25
Abstract: In this process for forming an internal screw thread in a tube or link made from a composite carbon fiber based material coated with polymerized resin, the part of the tube or link comprising the screw thread is inserted in the body of the tube or the link and molded on a threaded mandrel. This part of the tube or link where the screw thread is to be formed is polymerized substantially completely and under pressure on the threaded mandrel so as to obtain a preform comprising a hard internally threaded portion extended by non polymerized fibers; an expandable mandrel is introduced into this preform; the preform is inserted inside a tube which is already polymerized or to be cured; and finally polymerization under pressure of the fibers is provided by heating and causing the mandrel to expand so as to bond them to the fibers of the tube.

Title: Adjustable feedback for a coextrusion die
Inventor: DEHENNAU CLAUDE
IPC: B29C48/495
Filed: 1985-10-08
Granted: 1989-02-16
Abstract: An adjustable feed block for a coextrusion die is provided. The feed block comprises a main central channel for conveying a main stream of molten thermoplastic material towards a coextrusion die, and at least one secondary channel, substantially parallel to the central channel, for conveying a second molten thermoplastic intended to form a local coating layer on the main stream. The downstream end of each secondary channel is inclined relative to the central channel and connected to a portion of the periphery of the said channel. The connection between the central channel and each secondary channel is laterally delimited by the ends of two adjustable slides which can be moved at right angles to the axis of the central channel. These slides make it possible to adjust, during operation, the position and width of the streams of thermoplastic deposited on the main stream. Preferably, each secondary channel is subdivided into two curved branches which join together again upstream of the connection to the central channel, in such a way as to form an angle substantially equal to 180 DEG  between them. Each secondary channel can be equipped with an adjustable distributor. The novel feed block is particularly suitable for coextrusion of profiles such as profiles for door frames or window frames.

Title: Squeeze out piston for vessels
Inventor: HOFFMANN ARMIN
IPC: B65D35/30
Filed: 1985-01-25
Granted: 1989-08-17
Abstract: A press-out piston is movably displaceable through an axially extending container holding a flowable plastic substance for dispensing the substance as the piston is forced through the container. The radially outer circumference of the piston has an annular groove in which an elastically deformable sealing ring is positioned. The base of the groove is conically shaped about the axis of the container and diverges outwardly toward the rear end of the container. When the piston is pressed toward the front end of the container for dispensing the substance, the sealing ring is moved axially relative to the piston and is pressed radially outwardly against the inside surface of the container. As a result, the seal for the piston is dependent on the pressure directed against the substance for dispensing it out of the container.

Title: Games racket
Inventor: CURTIS MICHAEL EDWARD
IPC: B29C45/26
Filed: 1985-06-24
Granted: 1989-09-21
Abstract: The invention relates to a frame for a games racket e.g. tennis, of the type made as a hollow injection moulding of reinforced thermoplastics material. The frame has stringing means in the form of a series of discrete lugs (17, 28 or 40) moulded integrally with the walls of the hollow frame and so positioned that the racket strings in their desired positions do not pass to the outer periphery of the head. The discrete lugs may for example be around the inner periphery of the head of the frame and each contain an integrally-moulded circumferential bore (18) for string passage.The frame may be made by injection moulding around a fusible core (10, 21 or 30) and the shape of the core required to give the desired lugs provides strong resistance to movement under the injecting pressures hence giving improved product uniformity.
Patent DE-3585407-D1 (DE)
Inventor: DRYNAN DAVID SCOTT
IPC: H04L1/16
Filed: 1985-12-03
Granted: 1992-03-26
Abstract: In a packet data transmission system, correctly received information packets are acknowledged by piggybacking their sequence numbers onto information packets being transmitted. The control field of each information packet includes a bit which indicates whether or not there is a piggybacked acknowledgement. Acknowledgements can also be transmitted separately in control packets having no information field. Each acknowledgement consists of not only the sequence number of a correctly received information packet, but also the acknowledgement status of a plurality of preceding information packets whereby these can be negatively acknowledged if necessary. The sequence numbers can have any one of three different sizes, for efficient transmission of sequence numbers on transmission links of arbitrary transmission speed and length (and hence delay), The sequence number size which is used on any particular transmission link is determined on set-up of the link in dependence upon the transmission speed and the round-trip delay of the link.
