Title: Picture phonograph record and method of making same
IPC: G11B3/70
Filed: 1979-09-24
Abstract: A picture phonograph record has an imprinted core sheet sandwiched between transparent layers one of which comprises a relatively thin preformed plastic foil and the other of which is a relatively rigid and thick layer dispersed radially over the core sheet from a hot fluent lump of plastic positioned between heated pressurized mold platens. Sound tracks are impressed onto the face of one or both plastic layers concurrently with the extrusion of the lump to form the thick plastic layer. At least the thicker and usually both layers become inseparably adherent to the adjacent face of the core sheet as an incident of the assembly and sound track impressing operation.

Patent GB-2062936-A (GB)
Title: Record player having selective stylus translation facility
IPC: G11B21/02
Filed: 1979-02-12
Abstract: A video disc player stylus is lifted or lowered in relation to a carriage 108 used to carry the stylus horizontally. The lifting takes place to disengage the stylus from the record e.g. using a two-position thumbwheel 252. Normal playback drives carriage 108 radially of the turntable 26 in one direction in synchronism with its rotations. For search or special effects operation, the turntable continues to rotate and the stylus remains lowered and engaged with a record. However, the radial movement of carriage 108 is no longer synchronised but is manually controllable in either direction using another thumbwheel 160 at the control panel. A three-position toggle switch 134 couples the carriage either to a search/ special effects belt 132 manually rotated by thumbwheel 160, or to a normal drive belt 130, or the toggle switch can disengage the carriage from either belt. An alternative (Figure 16) for achieving special effects and playback radial carriage drives uses a permanently engaged special effects thumbwheel, and a clutch engaged normal playback motor, so that the special effects thumbwheel rotates during normal playback and indicates which part of a record is playing at any moment. <IMAGE>

Reinforcements and bracing elements are connected to the flanges 10, and the pool is completed by a coping member sealingly engaging a water retaining flexible liner. <IMAGE>
Patent GB-2097601-A (GB)
Title: Cord grips for electrical plugs or appliances especially for non-rewireable plugs
IPC: H01R13/68
Filed: 1981-04-27
Abstract: A plug or appliance casing has a tapering housing (21) defined by base (2) and/or cover (3, Figure 1, not shown) which receives a cable gripping member (10) which fits tightly around the cable (1) and has an exterior tapering shape matched to the housing (21). Because of the taper, member (10) is retained spaced from end (22) and if tension is applied to cable (1), the cable gripping member (10) is compressed more tightly round the cable (1), so as to prevent it being pulled out unless very substantial forces are applied. If such forces are applied, an earth wire may be made to be the last to sever its connection with a terminal pin (4) by leading live and neutral conductors around posts (20) moulded integral with the plug base (2). The cover (3, Figure 1, not shown) may be secured to the base (2) by ultrasonic welding. <IMAGE>

Title: A method and apparatus for welding sheets of thermoplastic material
IPC: B29C65/32
Filed: 1981-07-21
Abstract: Sheets of thermoplastic material are welded together by passing a hot wedge 5 between overlapping edges 3, 4 of the sheets so as to melt the surfaces 1, 2 of the sheets in contact with the wedge, adding a small amount of molten thermoplastic material between the overlapping edges and thereafter pressing the edges together, e.g. by a roller 7, so that when they have cooled any voids and creases are filled with the additional thermoplastic material. The wedge 5 may be heated by an induction coil 6, Fig. 1, or by the passage of a high amperage low voltage electric current therethrough, Fig. 2 (not shown). The temperature of the wedge is controlled by a controller connected to a temperature sensing device 8 located at the pointed end of the wedge. The additional thermoplastic material may be supplied through a nozzle (18), Fig. 3 (not shown), near the pointed end of the wedge. Alternatively, this material is introduced at the side of the wedge and the roller, Fig. 4 (not shown). <IMAGE>
Patent GB-2083212-A (GB)
Title: Method for simultaneous measurement of borehole and formation neutron decay-times employing iterative fitting
IPC: G01V5/10
Filed: 1981-08-14
Abstract: A borehole and earth formations in its vicinity, are repetitively irradiated with pulsed fast neutrons, and during the intervals between pulses, capture gamma radiation is measured in at least four, non-overlapping, contiguous time intervals. A background radiation measurement is made between successive pulses and used to correct count-rates representative of thermal neutron populations in the borehole and the formations, the count-rates being generated during each of the at least four time intervals. The background- corrected count-rate measurements are iteratively fitted to exponential curves using a least squares technique to simultaneously derive signals representing borehole component and formation component of the thermal neutron decay time. The signals are recorded as a function of borehole depth.

Title: Chain engaging devices
IPC: F16G15/00
Filed: 1981-12-03
Abstract: A chain engaging device has a clevis end 4 to permit of attachment to an eye 8 of a standing length of wire rope 10 or chain. A main body portion is formed with a longitudinal surface groove 14 and a lobed jaw portion 16 to accommodate links 24 and 32 of a length of chain 26. The link 32 is retained on seating faces formed in the lobed jaw portion by the action of a spring-biassed plunger 52 engaging a peripheral portion of the link 24. Movement of the plunger against the spring bias brings a circumferential groove on the plunger into register with the link 24 thereby permitting movement of the link 24 past the plunger and disengagement from - or engagement into - the lobed jaw portion 16. <IMAGE>

Title: Expanding shoe drum brake for a trailer with overrun braking
IPC: B60T7/20
Filed: 1981-12-17
Abstract: The brake comprises a primary shoe 1 and a secondary shoe 2 actuable by floatingly-mounted pressure applying means, and control means to control the spacing of shoes 1, 2 at ends remote from the pressure- applying means in dependence on the travel direction. The control means comprise a pivotable lever 3 urged by spring 8 to a rest position and engaged by shoe 2 to be so pivoted out of the rest position on actuation of the shoes during reverse travel as to effect a reduction in the spacing of said shoe ends. The lever 3 in its rest position is frictionally supported (at support 7 as in Figure 1 or at support surface 12 of shoe 1 as in Figure 2) whereby the lever 3 is subjected to frictional resistance to pivoting out of the rest position. Figures 3, 4 show modifications based on Figure 1 where lever 3 is again 'shape-lockingly' mounted on primary shoe 1. Figure 3 has a spring (10) connected between shoe 1 and support 7. In Figure 4 the abutment 9 of Figure 1 is displaced by a length (I7). <IMAGE>

Title: Method for measuring rate flow of liquids
IPC: G01F1/00
Filed: 1982-01-20
Abstract: The rate of flow of liquid from a closed container 1 through an outlet 6 is determined by measuring the rate at which air enters the container to replace the liquid a flowmeter 15 being connected to an air vent 13 of the container. The flow meter 15 is calibrated in terms of rate of flow of liquid material, and includes a pointer 17 opposite calibrations 18 to give a visual display of said rate of flow. The container is gravity fed from a tank 2; an inverted V-tube 11 prevents liquid overflowing into the meter.
