Patent GB-2177642-A (GB)
Title: Assembly of electronic components
Inventor: CHERIAN GABE
IPC: H05K3/34
Filed: 1986-08-01
Abstract: A chip carrier mounting device which is hereinafter also referred to as an "interconnection preform placement device" includes a retaining member having a predetermined pattern of apertures in which are positioned preforms of joint-forming material such as solder. The preform retains its general configuration after the interconnection or soldering process to form a resilient joint which is more capable of withstanding stress, strain and fatique. A method of forming resilient interconnections comprises placing the interconnection retaining member device between parallel patterns of electrically conductive elements, such as the conductive pads on an electronic component and a circuit board, and effecting the bonding of the conductive elements with the preforms. The joint-forming material may be a filled solder composition or a supported solder which substantially maintain their physical shape when the solder is molten, or a conductive elastomer.

Title: Tape lacing mechanism
Inventor: HENSHAW JAMES REYNOLDS
IPC: G11B15/295
Filed: 1986-09-17
Abstract: Tape lacing in a recorder with magnetic heads 40-46 fixedly mounted on a deck 12 between single capstan 52 and a (damped) idler 50 comprises moving (semicylindrical) tape guide 34 in recess 28 in cassette body 14 and moving idler rollers 36 and 38 in recess 32 in the cassette body to the loaded positions as shown, tape 20 being thus constrained to follow a looped path into the interior of which its front surface faces and within which are situated capstan 52, the magnetic heads and idler 50. Thereafter, pinch rollers 56 and 58 are moved vertically downward towards the surface of the deck 12 and then perpendicular to their axes so as to bring them into contact with the tape on the capstan surface (also (Figs. 3, 4)). They are advantageously fixedly mounted on a support (60) pivotable about an axis spaced from and parallel to their own axes so as to allow automatical equalisation of their pressures on capstan 52. Lacing may involve translation of the pinch rollers 56, 58 (Figs. 5, 6, 7), and the heads may be on opposite tape runs (Figs. 6, 7). <IMAGE>
Patent GB-2184132-A (GB)
Title: Recovery of copper-rich phases from lead bullion
Inventor: HOPKIN WILLIAM
IPC: C22B15/00
Filed: 1986-11-25
Abstract: Lead bullion, from lead smelting or zinc/lead smelting furnaces and containing 4% to 60% copper, is granulated and subsequently subjected to a copper-recovery operation. This avoids problems of copper dross solidification in pipes and treatment vessels. Granulation may be by water or air-quenching; mutual impingement of jets of molten bullion, or by mechanical means. The copper may be recovered by a continuous drossing operation; melting followed by slow cooling; physical separation; leaching; fuming off lead or electro-refining.

Patent GB-2203729-A (GB)
Title: Closure systems for containers
Inventor: BROWNBILL THOMAS DUNCAN
IPC: B65D41/04
Filed: 1987-03-19
Abstract: A container of a substantially rigid material has spaced lugs (16) formed on its neck for engagement by complementary lugs (56) on the skirt of a plastics closure (50). In order to prevent the closure from "backing-off" during prolonged storage, each container lug has a rib (36) along which the associated closure lug must ride when the closure is being applied. The closure lug provides a space (62) in which the rib is accommodated when the closure is fitted. Further surfaces (58, 32, 60) on the container and closure prevent overturning and limit downward movement of the closure. <IMAGE>

Title: Hydraulic noise attenuators
Inventor: HENDERSON ANDREW ROSS
IPC: F16L55/033
Filed: 1988-08-10
Abstract: A hydraulic noise attenuator for attenuating noise in hydraulic pipelines (10a, 10b) comprises an outer pressure resistant casing (11) through which extends a tube (12, 13) which in use forms a part of a hydraulic pipeline. The interior of the casing (11) is filled with hydraulic fluid and perforation(s) (16) in the enlarged tube (13) provide pressure balance and direct fluid communication between the fluid in the tube (13) and in the casing (11). The perforation(s) (16) in the tube (13) are spaced from or shielded from the flow of hydraulic fluid in the tube (13) so as to maintain the performance of the attenuator at high flow rates of hydraulic fluid within the tube (13). The shielding may be effected by extending the tube (12) into the enlarged tube (13) (Fig. 2) or providing a constriction in the tube (12) (Figs. 3 and 4). <IMAGE>
Patent GB-2213444-A (GB)
Title: Vehicle water filling systems
Inventor: TWEEDIE WILLIAM ARTHUR
IPC: B60S1/50
Filed: 1988-12-05
Abstract: A water reservoir 6 of a vehicle, such as the reservoir of a screen washer system, is filled with rainwater by way of an inlet assembly 2 positioned in an upper surface of the vehicle within a drainage channel 3. The inlet assembly 2 is connected by a flexible pipe 4 to a filling assembly 5, incorporating a filter, for filling the water reservoir 6. A further flexible pipe 7 conducts excess rainwater to a drainage point. Such an arrangement dispenses with the need to top up the water reservoir, and prevents the screen washer system from running out of water. <IMAGE>

Title: Water meter installations adaptor with valve
Inventor: GALE STEPHEN ANDREW
IPC: F16L55/07
Filed: 1991-01-05
Abstract: In order to avoid excavating a large hole in the ground to house a water meter and shut-off valve, a compact adaptor (8) incorporating a shutoff valve (18) is provided to connect inlet and outlet passages of a water meter directly to inlet and outlet passages (4, 5) in the body of an existing stopcock (1). The adaptor (8) has at its lower end coaxial inlet (12) and outlet (10) tubes which seal respectively with the stopcock valve seat (7) and stopcock body spigot (9), and coaxial tubes (16, 17) at its upper end for connection to the coaxial inlet and outlet of the water meter. The shut-off valve is advantageously a ball valve which controls both the supply and return flows from the water meter, the ball valve member having independent flow and return passages (22, 23), but in one construction (Figure 5) only the supply passage is controlled by the ball valve. <IMAGE>

Patent GB-2253906-A (GB)
Title: Supplying fluid and measuring the amount supplied
Inventor: BOUCHER ROBERT FRANCIS
IPC: F23N1/02
Filed: 1992-02-25
Abstract: A package burner 2 has a casing 4 in which a drum fan 8 is rotatably driven at constant speed by an electric motor. Air flow from the surrounding atmosphere is induced through an open end 16 of a conduit 14 which guides the air through the opening 18 into the casing 4 from which it is propelled by the fan down the outlet 6 to mix as combustion air with fuel gas at a gas supply nozzle 20 so that flames issue from the combustion chamber 24. A butterfly valve 28 can be set to regulate how much air is supplied as combustion air. A fluidic oscillator 34 has an inlet pipe 36 open to the atmosphere at 38 and has an outlet pipe 40 open at 42 to the conduit 14. The observed frequency of the fluidic oscillator 34 is a function of the flow rate of air flowing through the fluidic oscillator and is a function of the flow rate of air flowing along the conduit 14. Therefore the measured frequency of the fluidic oscillator can be used to calculate the amount of air being supplied along the conduit 14 in unit time. <IMAGE>
