Patent GB-2172343-A (GB)
Title: Methods and apparatus for pumping fluids e.g. hand operated bore-well reciprocating pumps
Inventor: BULLIVANT EDWARD GEORGE
IPC: F04B53/14
Filed: 1986-03-07
Abstract: A reciprocating pumping system uses rolling lobe diaphragms 34 as sealing means between piston 30 and cylinder 31. Non-return valves (17 not shown) and 16 govern entry of fluid into cylinder 31 and piston 30, respectively, in the conventional manner. Non-return valve 36 permits fluid to flow into chamber 37 between two diaphragms 34 to assist them to maintain their operating shape. In another embodiment, cross-bore 20 and the single, uppermost diaphragm 34 are dispensed with, the fluid passing directly to the outlet by means of a tube connected to the piston bore. The piston is reciprocated by means of a lever. <IMAGE>

Title: Parts inspection equipment
Inventor: NISHIMURA TAKESHI
IPC: G01B21/02
Filed: 1986-03-13
Abstract: A parts inspection equipment includes a plurality of dimension measuring devices (10, 12, 14, 16, 18) for measuring portions of respective parts. The equipment specifies the portions to be measured of the respective parts, and the measuring device suitable for the said portions. The equipment further stores the results of the measuring steps, reads measured values of the respective dimension measuring devices, processes the data thus read and outputs the same as the measured result information. With the above- described arrangement, a worker can concentrate his attention on the measuring operation without being annoyed by individual and optional works such as selection of the dimension measuring machine, consideration of steps of the measuring operation, reading of the measured values, processing of the measured results and the like. <IMAGE>

Patent GB-2184103-A (GB)
Title: Valve fitting
Inventor: GOTCH HENRY
IPC: B25B13/44
Filed: 1986-12-15
Abstract: A valve fitting for the bung hole outlet (51) of a cask (50) has a body part (54) carrying the valve assembly (56, 57) and extractor tube (55). Threading (62) engages the internal threading (52) of the outlet (51). The top plate (59) of the fitting is a separate ring which engages the threading (52) by threading (60). This arrangement provides a safeguard against removal of the fitting from the cask. Removing the top plate (59) leaves the valve assembly (53) intact with no means of applying purchase to achieve unscrewing of the fitting. A special tool may be used to remove the fitting (53) if required.

Title: Cutting and creasing forme for blanks
Inventor: MORRIS GEOFFREY MAURICE
IPC: B31B50/22
Filed: 1987-01-26
Abstract: The forme comprises a main die 2 with cutting blades 3 and creasing rules 4 and a counter die 5 with creasing grooves (6, Fig. 2) which correspond with respective creasing rules 4 of the main die 2, wherein the main die 2 is provided with holes 9 for receiving therein respective locating pins (35, Fig. 4) for locating the two dies 2, 5 in registration with each other, the holes being defined by at least three, and preferably six, planar surfaces extending into the main die 2.

For setting the counter die up on the main die, a shoulder in the holes 9 locates the pins (35 at the right height and a press plate 40, Fig. 4) is brought into contact with a contact adhesive layer on the counter die and simultaneously urges the pins into a smaller cross-sectioned portion (911) of the holes below the shoulder, compressing rubber ejector blocks (11) so that the pins are driven so far into the holes to prevent their interfering with the cutting and creasing operations. <IMAGE>
Patent GB-2201219-A (GB)
Title: A system to detect contents release from pipes, tanks or valves
Inventor: POLLITT JAMES WALLACE
IPC: G01M3/04
Filed: 1987-02-19
Abstract: Occasionally water and electrically conducting liquids will leak from pipework, tanks or valves when corrosion, excess pressure, freezing or other events cause damage. The invention is a tape or cable incorporating one or more electrical conductors in proximity but separated by material which when dry is largely a nonconductor of electricity. The material is absorbant and porous to water and electrically conductive liquids so that when wetted an electrically conducting path is formed between the conductors, one of which may be the pipework, tank or valves. A simple electronics package connected to the conductors monitors the electrical properties of the tape and thereby establishes if the tape is wet or dry. Signals produced by the electronics package can then be used for warning or control purposes. <IMAGE>

Patent GB-882082-A (GB)
Abstract: 882,082. Controlling burners. KREFFT A. G., W. Feb. 20, 1958 [Feb. 20, 1957; Jan. 25, 1958], No. 5587/58. Class 75(1) [Also in Group XL(b)] In a gas lighting and protection arrangement for gas burners in which a burner is automatically ignited when a cock in its gas supply is turned on, the gas supply passage is closed, in the event of gas failure, and is opened and the burner reignited when the supply is restored. A gas burner 11 is supplied via magnetically controlled gas cock 10 and a manual cock 5. Operation of the cock 5 completes an electrical circuit supplying energy to an ignition transformer 3 and a mains transformer 2 which produces the power supplies for the circuit of a thermionic valve 6. The gas issuing at a pilot jet outlet 4 is ignited by the ignition supply and the jet heats a negative temperature coefficient resistance 8a which is connected in a bridge arrangement in the grid circuit of the thermionic valve 6. The valve grid is biased negatively by a D.C. supply from rectifier 7 but as resistance 8a is heated this bias is reduced and the valve conducts. Relay 9 in the anode circuit of the valve energizes and actuates via one of its contacts the magnetic cock 10, which on opening supplies gas to the burner 11, and at another of its contacts breaks the electrical supply to the ignition transformer 3. In the event of gas failure, resistance 8a cools and the resulting increase in grid bias reduces the flow of current through valve 6. Relay 9 de-energizes and breaks the circuit controlling the magnetic cock which subsequently closes and also restores the electrical supply to the ignition transformer. When the supply is restored the gas is re-ignited as previously described.

Title: Bracket assembly for a dish antenna
Inventor: SINCLAIR CLIVE MARLES
IPC: H01Q1/12

Abstract: A dish antenna bracket is formed from a dish bracket (10) for fixing to the dish antenna. This is pivotally coupled to an intermediate bracket (16), about a first axis, which is in turn pivotally coupled to a wall bracket (23), about a second axis. Each pivotal connection includes a pair of flanges (22, 26) and each flange of this pair has a circle of holes (28) concentric with respective axis. The holes (28) in each flange are equispaced but the holes in a first flange of the pair have a different spacing to the holes in the second flange of the pair. Thus there are a large number of closely spaced positions in which a hole in one flange lines up with a hole in the other flange for insertion of a positioning screw. <IMAGE>
