Patent GB-2148399-A (GB)
Title: Compression of air for use in water treatment plant
Inventor: STEVENSON DAVID GEORGE
IPC: C02F1/24
Filed: 1983-10-06
Abstract: Air is compressed in a positive manner using the high pressure water to be treated as the energy source. A measuring vessel (1) is first allowed to drain down under atmospheric or reduced pressure to waste (3) via a valve (2). High pressure water from a pump (7) is then admitted through a valve (6) and the air compressed and subsequently forced forward through a valve (8) to the point of use, which may be, for example, the absorber (10) of a dissolved air flotation plant. The cyclic draining and repressurisation may instead be controlled by a three-way valve. Whichever valve arrangement is adopted it can be operated automatically by a timer, or by level probes in the measuring vessel. <IMAGE>

Title: Masonry fixing device
Inventor: LUNN PETER LOUIS
IPC: F16B13/12
Filed: 1984-07-02
Abstract: A fixing device 10 for use with a wood screw 17 is formed from sheet metal into a tube so as to have one slit 12 from end to end and another slit 18 part-way along the tube from the rear end 14. The front end 13 of the tube is partly closed in to form a nose with a hole 15 for the tip 16 of the screw 17. The edge of the hole 15 is shaped to engage the thread of the screw. The length of the device 10 is less than four times its maximum diameter. In use, penetration of the device 10 by the screw 17 expands the front end 13 of the tube so as to increase the maximum diameter of the device 10. In use, a hole 19 is drilled in masonry 20, device 10 is inserted into the hole 19 part-way along the length of the hole 19 and the "wood" screw 17 is then screwed home so that it expands the device 10, which thereby becomes securely fixed in the masonry. This applies to non-yielding masonry such as brick work. For yielding masonry, particularly porous masonry the fixing device may be hammered into the masonry using a setting tool 22. <IMAGE>

Patent GB-2190028-A (GB)
Title: Perforating plastics film
Inventor: CLEGG ALAN JAMES
IPC: B26F1/28
Filed: 1986-05-08
Abstract: An apparatus and a process for perforating synthetic plastics film, for example polyethylene or polypropylene, uses an electrical spark discharge set up between a set of first electrodes which may be pointed rods 2 and second electrodes which also may be complementary pointed rods 3 or a single electrode which may be an electrically conducting guide plate, vane or roller. The film is drawn between the firstand second electrodes. Each first electrode is supplied with high voltage sufficient to cause the spark discharge from a separate charged capacitor 11 whereby each first electrode is electrically isolated from the others and thus a discharge from one first electrode does not prevent the formation of discharges from the other electrodes. The charging and discharge of the capacitors is controlled by a series of coupled switching units. <IMAGE>

Patent GB-2182830-A (GB)
Title: A decision circuit particularly for a switching device
Inventor: KAUSHAL TEJ PAUL
IPC: H04M9/10
Filed: 1986-11-06
Abstract: A decision circuit, such as is used in voice-switches (eg for a loudspeaking telephone) comprises two inputs (I/P A and I/P B). Input signals are buffered by means of buffers PA and PB, and then integrated by means of integrating network (RA, CA and RB CB). The integrated voltages (VA and VB) are applied to the inputs of a comparator (M) in order to generate an output (O/P : A/B), which in turn operates the switch. Cross-coupling between the two input sides of the circuit by means of a resistor (RX), interconnecting the integrators, ensures that the steady state potential on each integrator is not less than a set proportion of that on the other integrator and decreases the response time. <IMAGE>
