Title: Method of fusion bonding non-elastomeric thermoplastic elements with a block structure elastomeric bonding element interposed at the bonding interface
IPC: B29C65/36
Filed: 1978-09-05
Abstract: A solid block elastomeric bonding element 5 is interposed between the surfaces 3, 4 of a pair of non-elastomeric thermoplastic elements 1, 2 to be joined by a fusion bond. The heat necessary for fusion bonding is obtained by the incorporation of heat generating particles in the elastomeric bonding element 5. The particles are indirectly heatable by a high frequency alternating magnetic field, established by a coil 7 energized by a high frequency current source 8 and having copper plates 9, 10 affixed thereto, or other suitable field for heating the fusion bonding element 5 to a fusion temperature suitable for producing bonding of the non-elastomeric elements. In a high frequency magnetic field, preferred particles are gamma Fe2O3, Fe3O4 or mixtures thereof. Other specified particles are dielectrically heatable particles, e.g. of halogenated polymers, and infra-red energy heatable particles, e.g. carbon black. Also disclosed is a method of bonding a plastics element to a non-plastics element, e.g. glass, by coating the latter element with a phenoxy resin primer, interposing a film of a thermoplastic block elastomer between the elements and heating the assembly. <IMAGE>
Patent GB-2006373-A (GB)
Title: I. C. Engine Valve Clearance Regulating Means
IPC: F01L1/245
Filed: 1978-10-10
Abstract: A hydraulic valve tappet (100) comprises a tubular housing (112), and a piston (113) abutting a socket (114) and both slidable in the housing. A pressure chamber (126) below the piston crown (113A) is controlled by a non-return ball valve (116, 115A). Pressure oil from the engine lubrication system is admitted into the housing and can enter the chamber through the valve and be trapped therein to maintain normal valve clearance. A sliding plunger (133) is spring-biassed towards the piston crown and engages the ball (116) to open the valve and vent the chamber (126) when the oil pressure in the housing is below a threshold value, thus collapsing the tappet and increasing the valve clearance above the normal running value. When the oil pressure in the housing exceeds the threshold value it overcomes the plunger spring and lifts the plunger, allowing the valve to close and trap oil in the chamber, so reestablishing the normal valve clearance. Thus for starting up, the tappet provides increased valve clearance so long as the oil pressure is low, thereby facilitating starting by shortening the valve opening period. <IMAGE>

Title: Improvements in fastening elements for building panels
IPC: F16B13/06
Filed: 1978-11-07
Abstract: This invention concerns a rivet- like fastening element made of resilient plastics material and comprising an axially slit anchoring portion 5 which expands outwardly to form a support in contact with the back of the panel 8. To prevent the screw from pulling through, the shank portion of the fastening element accommodates an internally screw-threaded top hatted bush 4 which is secured by ribs 11 against twisting and axial movement relative to the shank portion, the material forming the bush being stronger and less resilient than the material forming the shank portion. In Figure 2 (not shown) the portion 5 has no top hat end but is provided instead with several tail fins. <IMAGE>

Title: Packing material cutting mechanism of coin packing machine
IPC: B26F3/02
Filed: 1978-11-28
Abstract: A packing material cutting mechanism of a coin packing machine including a plurality of packing rollers 13 arranged to wrap a pile of coins 4 with a web of packing material 1, comprises a cutter blade 3 between a pair of web feed rollers 23, 24 and the packing rollers 13 disposed so that an increase of the tension of the length of web 1 between the feed rollers 23, 24 and the packing rollers 13 causes the blade 3 to sever the web 1. In order that the angle between the web 1 and the blade 3 remains constant when the relative position of the blade 3 with respect to the packing rollers 13 is changed to alter the length of web cut, the blade 3 and the feed rollers 23, 24 are mounted for conjoint movement about an axis 15. A lever 21 permits adjustment of the cutter blade 3 so that the mechanism can cut off the different lengths of material for different diameters of coins. <IMAGE>

Title: Process and apparatus for removing a portion of a row of continuous fastener members from a sliding clasp fastener
IPC: A44B19/58
Filed: 1979-01-11
Abstract: In apparatus for gapping a sliding clasp fastener stringer, the fastener members being devoid of internal cord and formed from a plastics monofilament defining coupling heads, backbends 7 and arms 5 which are embraced by sewing thread loops 4 attaching the members to a carrying tape, cutters 10, 11 are positioned at the ends of the portion to be gapped. These cutters sever the monofilament at both ends of the portion, but the cutter 11 additionally grips a backbend adjacent one end of the portion. The stringer is mounted on a feeder 9 movable in the longitudinal direction of the stringer thereby pulling the stringer away from the cutter 11 gripping the backbend so that the fastener members to be removed are pulled one-by-one from the sewing thread loops. <IMAGE>

Title: Dynamoelectric Machines: Pole-Piece Arrangements
IPC: H02K1/14
Filed: 1979-06-19
Abstract: In an electric motor of the kind described in British Patent Application No. 48794/74, interpolar flux-leakage is reduced by radially staggering the U-shaped pole pieces around the stator coil (Fig. 4). In addition or alternatively differently shaped pole pieces may be employed, alternately, around the stator assembly (Fig. 5). Iron losses may be reduced by laminating the rotor backing plate (2, 4). Although a spiral lamination is preferred, an axial stack of insulated plates may be employed. Eddy current losses may be reduced by the replacement of the backing plates with plates of sintered magnetic material, or forming backing plates from sintered ferrite material mounting either an array of discrete magnets or a magnetised ring therearound as described in U.K. Patent Specification 2,006,540 (Application No. 7839029) out of which the present application is divided. <IMAGE>

Abstract: A plate type evaporator comprising a plurality of vertically extending plate elements (1a-1f) assembled face-to-face to define therebetween alternate channels (A,B) for a heating medium and for a liquid to be evaporated. In order to accelerate the nuclear boiling of the liquid in the liquid channels, the heat transfer surface of each plate element (1a-1f) has a plurality of vertically extending transversely spaced ridges (2) projecting toward the associated liquid channel, such ridges (2) being in contact with the heat transfer surface of the opposed plate element (1a-1f) to provide areas of contact (3) assisting in the evolution of vapor bubbles and divide the liquid channel into narrow sections (4A) assisting in the generation of vapor, such sections (4A) also assuring that even in deeper places in the liquid channel, vapor bubbles will be generated without yielding to the liquid pressure; alternatively (Fig 5, not shown), each plate element (21) has a porous layer (23) formed on its heat transfer surface facing the liquid channel. These heat transfer constructions permit attainment of even higher boiling heat transfer if the liquid in the liquid channels is caused to circulate. <IMAGE>

Title: Integral Storage Collector Solar Heating System
IPC: F24J2/34
Filed: 1980-08-28
Abstract: In an integral storage collector solar heating system, water heated in a conventional hot water heater is first preheated in an integral storage collector (22). The storage collector (22) includes a heat storing medium (46), preferably clean water, in a storage tank (40). Water to be heated is forced by line pressure through heat exchange pipes (44) immersed in the heat storing water (46). The heat of fusion of the storing water prevents freezing of the line water. To preclude excessive pressure in the heat storage tank with high temperatures of the heat storing water, a heat pipe (52) is provided to act as a large heat leak at about the vaporization temperature of the water. Also, a pressure relief valve (48) is provided. The system avoids freezing and contamination of the water and does not require temperature control circuitry or a pump. <IMAGE>
