Abstract: 1323592 Moulding embossed sheet material; laminating ANVER SA 8 July 1970 [22 July 1969] 33060/70 Headings B5A and B5N [Also in Division B6] Material comprising a support sheet upon which is located a layer of embossed thermoplastics material is made by forming a die having a configured surface from a low dielectric loss material, impregnating an absorbent sheet of thermoplastic material with a meltable plastics of the same chemical nature, bringing the impregnated sheet into overlapping relationship with a support sheet and pressing the die against the overlapped sheets whilst applying a high frequency electric field to melt the components of the absorbent sheet, to shape the sheet thus melted and to bend it to the support sheet. Preferably the die is of a silicone based material and is formed by a casting operation. The impregnating plastics may be in liquid, paste or powder form and both the absorbent sheet and its impregnant may be of P.V.C., in which case the supporting layer is preferably leather or a textile material. If desired, a layer of reinforcing material such as glass wool, felt or cotton or even rubber is included in the finished article. As shown in Fig. 1 a support sheet 6 and an impregnated absorbent sheet are compressed and dielectrically heated between a silicone rubber die 3 and a flat support 2. In a second embodiment (see Fig. 3, not shown), a composite comprising a support sheet, an absorbent layer and a flat configured die are passed on a conveyer belt between a pair of pressure rolls connected across a source of high frequency current. In a third embodiment (see Fig. 4, not shown) such a composite is passed between the platens of a dielectric heating press. In the embodiment illustrated in Fig.- 5, an impregnated absorbent layer 5a and a support layer 6a are passed upon a belt 7 between dielectric heating pressure rolls 22 and 23, the upper of which 23 is provided upon its surface with configured mould cavities 23a. The strip thus formed is finally passed to cutting press 25 where individual articles are blanked out.

Title: Stuffer box crimping of yarns - using an annular stuffing chamber having perforated side walls
IPC: D02G1/12
Filed: 1972-01-05
Abstract: The stuffer box has a lower flat wall, an apertured upper wall, and a cylindrical perforated peripheral wall, and a synthetic filament tow is propelled through the aperture in the upper wall pref. by compressed air at an angle of 45 degrees to the lower wall, into the stuffer box to form an arcuate plug of yarn extending partially around the stuffer box. The stuffer box rotates with respect to the tow delivery position and crimped tow is continuously withdrawn via the aperture in the upper wall. The compressed air escapes through the perforations in the peripheral wall. Physical degradation of the tow is eliminated resulting in more uniform crimping.

Title: Cladding tile application process - positions tiles by setting devices before flooding with hardening material filling joints
IPC: E04F13/08
Filed: 1975-09-09
Abstract: The process is for the application of cladding tiles to a wall or floor, the joints between the tiles being of constant width and in line, while the tile surfaces are in the same plane. Between the surface to be covered and the tile edges towards it setting devices (11) are locally inserted, partic. at the corners, so as to give a predetermined width of joint seam (3, 4). The upper surfaces of the tiles are brought to the same level by local removal of material from them or the setting devices, or by moving the devices. After the surface has been completely covered with tiles, the surface formed by them is flooded with a filling material, initially in the fluid state. This fills the joints, and on hardening retains elasticity permanently, also having a good adhesion characteristic.

Title: Central heating control system - uses electronic logic to control operation of fuel valve, fan and alarm
IPC: F23N5/18
Filed: 1979-09-26
Abstract: This system is designed to control the operation of any central heating system having the following facilities; an electrically operated fuel-valve, a heat exchanger, a room temperature thermostat, a temperature sensor in the flue and an air-flow sensor. A circuit consisting of electronic logic gates, toggle circuits and timers ensures safe and economical use of the installation. The interlock circuits ensure that the fuel is supplied only if no alarm has been registered, the air-flow is sufficient, and the room thermostat is closed. The fuel is switched off if any of these conditions cease to be met. The fan operates immediately if the flue temperature is greater than 80 deg. C, or two minutes after the room thermostat has closed. An alarm operates if the air-flow is insufficient 20 seconds after the thermostat has closed.

Title: Plate out prevention in vinyl! or vinylidene! halide polymer - esp. suspension PVC, by using additive compsn. contg. drying agent, e.g. aluminium silicate
IPC: C08L27/08
Filed: 1980-11-19
Abstract: Plate-out from a vinyl(idene) halide (co)polymer (esp. plasticiser-free PVC) compsn. contg. conventional additives such as stabilisers and/or lubricants is prevented by addn. of a physically- or chemically-acting drying agent capable of binding escaping water (and pref. also HCl) when the compsn. is being plasticised (e.g. extruded or calendered). Also claimed are additive compsns. contg. the drying agents and methods for the prepn. of such compsns. Plate-out is considerably reduced, or even eliminated, when the drying agent is used with suspension- or mass-polymerised PVC, which contains occluded water, and HCl. The drying agent, by binding the water (or even the HCl), prevents reaction of the HCl with metal salts in the stabiliser. Thus formation of the Pb oxide-chlorides which plate-out during processing (e.g. during extrusion of pipes), is prevented.

Abstract: The property of phagocyte cells to show chemiluminescence when activated by certain chemical or immunological agents is used for a qualitative and quantitative analysis of such agents in biological fluids. A variety of factors such as opsonizing anti-bodies, complement, inhibitors, membrane-specific anti-bodies, and their antigens, membrane-specific lectins, lymphokines, endotoxins, toxic substances and others can be analyzed in this way. The new method finds application in the biotechnical, clinical, immunological and pharmacological fields, with a special preference for toxicological screening of pharmaceuticals. The phagocyte cells needed for the analysis can be derived from a continuous phagocyte cell line and a method of producing such a cell line is provided.

Title: Printing plate clamping mechanism for cylinder printing press - uses single clamp rail to secure both printing plate ends
IPC: B41F27/12
Filed: 1985-05-13
Abstract: The clamping mechanism employs an open groove in the surface of the cylinder containing a fixing device for holding the opposite ends (PA,PB), the printing plate which are both fitted into the groove. The fixing device employs a single clamp rail (17) for both printing plate ends (PA,P'B), having a longer width in the radial direction of the cylinder (1) than in the peripheral direction ad pivoted about an axis parallel to the cylinder axis. One side of the groove incorporates a biasing device (15,16) acting on the clamp rail (17) and a clamp piece (19) is fitted between the opposite side of the groove and the clamp rail. This defines two radial slits for securing the printing plate ends (PA,P'B) when the clamp rail is pivoted by the applied bias.

Abstract: An insulated wire is wound into a cylindrical coil by being continuously introduced into an annular space between a cylindrical core and a cylindrical sleeve coaxially surrounding same above a supporting surface which is rotated about their axis at an angular velocity W, the wire being fed in at a linear speed V. A processor is programmed to vary the ratio V/W according to the relationship (V/W)i= pi [D+2d)(ai-1)] where D is the diameter of the core, d is the wire diameter and ai is an integer representing the order number of the ith turn of a spiral path, counted from the core surface, along which the wire is laid in a succession of flat layers piled one atop the other. Each layer consists of n contiguous turns following one another in a radially outward direction in odd-numbered layers and in a radially inward direction in even-numbered layers, with decrementation or incrementation of the ratio V/W at the end of each turn. The discharge end of a feed tube is raised above the supporting surface, upon the completion of each layer, by an incremental distance equal to the wire diameter d to accommodate the next layer.
