Title: Lever tap unit
IPC: F16K21/04
Filed: 1979-05-31
Abstract: In a dispensing device for dispensing liquid from a container a body 10 is mounted by a tubular rear portion 11 in the wall 12 of the container. The body 10 is secured to the wall 12 by means of a nut 15 bearing against a flange 14 through a pair of cup washers 16 and O-rings 17. A valve stem 21 extends through the body 10 and is guided by a forward end 20 of the body. At the rear end of the stem 21 there is a head 22 which forms a poppet-valve cooperating with a seating 23 formed by the rear end of the body 10. At the forward end of the valve stem there is a block 24 which is biased by a helical spring 25 to close the poppet-valve. A lever 35 is pivoted about a fixed pivot 36 and is connected to block 24 by toggle link 39. When the lever has passed dead centre position, in which pivots 36, 38 and 40 are in line the lever 35 or link 39 bears against a stop (not shown) to hold the valve in the open position. <IMAGE>

Title: Composite Yarns
IPC: D02G3/04
Filed: 1979-06-19
Abstract: A composite yarn is formed from at least two continuous filaments, of which at least one is a partially oriented thermoplastics material, in combination with short discrete fibres, the filaments and fibres being twisted together. At least the partially oriented continuous filament is passed between a first pinch point (34, 36) and both filaments pass between a second pinch point (40, 42), discrete fibres are fed into juxtaposition with said filaments at position (54) between said first and second pinch points; and subsequently the filaments and fibres are subjected to a twisting force by twister (46) while between said pinch points. After the twisting step the filaments may be passed through a curved slot 58 and then around heating rollers (74, 76). The partially oriented filament permits the retention of a positive twist in the yarn by preventing the build up of counter torque due to intermolecular slippage. <IMAGE>

Title: Manually driven generating mechanism for doorbells
IPC: G08B3/02
Filed: 1980-08-28
Abstract: The present invention relates to an improved gyro-type manually operated dynamo mechanism applied to appliances consuming limited momentary power. Energy is stored by manually (21) stressing a spring (22) which keeps in mechanical connection with a train of acceleration gears terminating in a relatively heavy flywheel (27) when the stressed spring (22) is released to resume its unstressed state, and disconnects therewith when the spring (22) reaches unstressed condition and allows the flywheel (27) to rotate freely, thereby enhancing the exploitation of the energy stored in the flywheel (27) in the form of inertia to produce the requisite electricity by means of dynamo (28) to sound the buzzer. <IMAGE>
Patent GB-2067289-A (GB)
Title: Seismic pulse generator
IPC: G01V1/147
Filed: 1980-12-16
Abstract: In a seismic pulse generator 10 an impact mass 17, 20 is driven against a target plate 24 by high pressure gas stored in external accumulators 30. Piston 17 is normally held in the position shown by springs 22. When valve 51 is opened gas, at sufficient pressure to overcome the springs, is introduced into the bore 18. As the piston uncovers the large area ports 44 high pressure gas enters the bore 18 and drives the impact mass against the target plate. In a second embodiment the piston is tapered near the top and electrically controlled latches retain the piston in its upper position. When the latches release the piston the tapered portion enables the high pressure gas to exert a positive breakaway force on the piston. <IMAGE>

Title: Method of expanding tubular members
IPC: B21D39/20
Filed: 1981-01-12
Abstract: A two-stage method of expanding tubes 10 into holes in tubeplates 12 including walls of drums and headers especially in boilers using an elastomeric body 30 which in a first stage is compressed axially in the tube and which expands radially to expand the tube beyond its elastic limit into close engagement with the hole wall. In a second stage a second elastomeric body of different dimension is compressed axially to stress the tube and an annular zone of the tubeplate around the tube beyond their elastic limits. Problems of excessive extrusion of and damage to the elastomeric body where tolerances on tube or hole diameter produces excessive clearances are avoided even where high expansion forces are used. <IMAGE>

Title: Installation of piles
Inventor: EVERETT JOHN PETER
IPC: E02D7/26
Filed: 1982-10-20
Abstract: A pile 2 or other similar object such as a temporary or permanent pile casing is installed into the ground by driving or pushing the pile into the ground and at the same time introducing a settable liquid substance 7 such as liquid grout or concrete between the side of the pile and the ground into which it is driven. The presence of the liquid substance between the side of the pile and the ground lessens the frictional forces normally developed, thus reducing the energy required to drive the pile into the ground. <IMAGE>

Filed: 1982-11-24
Abstract: For enabling a body, e.g. a melt chamber and/or nozzle for a hot-melt composition, to be heated to and maintained precisely at a desired temperature, a predetermined temperature value is stored as a numerical value in a computer, and the output of a sensor, e.g. each of the thermistors (TS 1-3), mounted on the body, whose output is in the form of an analogue signal, is supplied to an A-D convertor which converts the signal to a numerical value, this output value and the stored value being then compared, at predetermined intervals, and a command being supplied to the respective heater circuit (H1-3) appropriate to the difference between the two values. When the temperature enters a predetermined band about the desired temperature, the heater circuit is energised by regular pulses of variable duration. <IMAGE>
