Inventor: HARRIES ROGER CHARLES
IPC: B29C63/46
Filed: 1987-07-16
Abstract: A method for lining a pipe with a polymeric material comprises forming a tube (7) of the polymeric material, subjecting the tube to a drawing process so that the diameter of the tube is reduced, inserting the tube into a pipe of inside diameter slightly greater than the outside diameter of the drawn tube and treating the tube to cause reversion expansion of the polymeric material such that the tube engages the inside wall of the pipe. The polymeric material is a polyolefinic material which exhibits two or more crystalline melting peaks when analysed by differential scanning calorimetry (DSC). The drawing process comprises cooling the formed tube and subsequently heating and drawing the tube at a temperature between the temperatures of the lowest and highest crystalline melting peaks.

Abstract: The invention is based on three-stage non-blocking and redundant switching networks; that is to say switching networks in which any switching block of a stage can film and freedom from blocking is still maintained. It is the object to extend such switching networks step by step with as little additional complexity as possible. The first and third stages are extended by additional switching blocks. In the second stage, the existing switching blocks are exchanged step by step for larger switching blocks. The extension is effected via so-called optimum extension stages comprising a minimum of switching blocks with full terminal allocation. In the invention, the extension can be effected during operation by releasing the switching blocks to be exchanged, via the redundant connecting paths.

Abstract: The invention relates to a process and a device to determine the internal pressure of an evacuated container. It assumes that two electrodes (3, 4), which are insulated with respect to one another, are provided in a container (1). A high electric voltage (U) is applied to the electrodes (3, 4), and an electromagnetic radiation outside the container (1) is detected by means of a probe (5). In this regard, the invention proceeds from the innovative realisation that when the voltage remains constant the variation in intensity of said electromagnetic radiation is overlaid by variations in intensity with a frequency that represents a measure of the internal pressure in the container (1). Consequently, an output unit (7) is provided in order to analyse and to evaluate said frequency variation, and thus to obtain data on the internal pressure. <IMAGE>

Abstract: Treatments for controlling psychological or psychosomatic disorders are very time-consuming both for the therapist and for the person being treated. An arrangement for carrying out psychotherapy is proposed, in which an auxiliary device for a television receiver influences the viewer during viewing of television broadcasts. In this case a first circuit arrangement is provided in order to temporarily exchange image signals coming from a transmitter with stored image signals. The exchange is effected in such a way that the interposed images have the desired influence on the viewer, but that the signals emitted by the transmitter can be received essentially undisturbed. In this way the treatment can be carried out in spare time. In addition, the therapist acquires a positive attitude to the treatment. <IMAGE>

Abstract: A recording/reproduction system performs high precision drop-out processing and compensation in the reproduction mode from a diskshaped recording medium (1) by using a recording format in which a video signal is divided alternately in units of one horizontal scan line into two channels, and the timing of the recorded video signal on one channel is displaced relative to that of the other channel, so as to record the divided signals on a pair of parallel spiral tracks (CH-1, CH-2) forming the two channels on the disk (1). A mean value interpolation circuit is provided in each channel for drop-out compensation, and a portion of a reproduced signal of one channel is compensated by a compensation signal produced by the interpolation circuit of the other channel.

Abstract: A detersive article, useful for charging an auto­matic washing machine with particulate built synthetic organic detergent composition, includes a detersive charge of such particulate composition in a closed container or packet which is formed by sealing about such composition a sheet or sheets of readily water dispersible water soluble cellulose compound and cellulose fibers, which is coated and/or covered or laminated with water soluble polyvinyl alcohol on interior surfaces thereof. The packet material dissolves or disperses rapidly when the packet is added to wash water in an automatic washing machine, and thereby releases contained detergent composition to the wash water earlier in the washing process than do other "dissolvable packets" which are made of poly­vinyl alcohol. When a soil release promoting agent (SRP), such as PET-POET copolymer, is present in the particulate detergent composition superior soil release promotion is noted when washing polyester and polyester blend laundry, compared to washing such laundry with controls wherein the SRP is in a detergent composition that is not in a packet, or is in a composition in a PVA packet, without any CMC/­cellulose sheet material being present.

Abstract: This invention relates to the preparation and use of very thin multiconstituent synthetic fibers. In accordance with the present invention, such fibers are produced from dispersions of incompatible polymers by meltblowing said polymeric dispersions. These procedures permit the preparation of very thin and highly attenuated polymeric fibers that contain microfibrils formed of different polymers. The practice of the present invention permits the preparation of nonwoven fabric webs having "customized" properties that make them suitable in a wide variety of applications. Also, microfibrils - which can themselves be used for various purposes - can be isolated from the multicomponent fibers of the present invention.
