Title: A vacuum gripper
Inventor: HOWARD FREDERICK WILLIAM
IPC: B66C1/46
Filed: 1984-04-19
Abstract: A remotely controllable gripper for picking up and setting down objects of various shapes and sizes, and of varying degrees of cleanliness, comprising a flexible skirt (10) flaccidly pendent from a lifting head (1) provided with a fluid extraction means.

Title: A theft deterrent and burglar alarm
Inventor: KAYE CHARLES MARTYN
IPC: G08B15/00
Filed: 1984-08-06
Abstract: A theft deterrent and burglar alarm comprises an electronic circuit which produces the synthesised sound of a dog barking when triggered by an external noise picked up by a microphone 1, or by a signal from a burglar alarm, movement detector 9 or other external contacts 4. An electronic doorbell 6 can optionally be included in the circuit giving both a chime and the sound of a dog barking when the bell push 6 is operated. A different phrase of barking is produced by speech synthesiser 10 each time microprocessor 5 is triggered and increasingly aggravated barking is synthesised if the trigger is continued. As the circuit has low power consumption in the idle state, it can be run from batteries so as to be independant of mains failure. <IMAGE>

Patent GB-2149685-A (GB)
Title: Improvements in or relating to liquid spraying
Inventor: ERICKSON JOHN WALDEMAR
IPC: B05B7/08
Filed: 1984-11-15
Abstract: A method of treating a polluted gas e.g., desulphurising a sulphur dioxide-containing flue gas is carried out by spraying the flue gas with a slurry of e.g. calcium hydroxide, under spray drying conditions. The spray device comprises a rotating spray cup 18 comprising an extended surface 74 on which a film of slurry is formed. On leaving the surface 74 the slurry is immediately impacted with a high velocity stream of air supplied through an annular orifice 22. Arrangements for supplying the slurry to the rotating cup comprise a stationary distribution device 17a adapted to direct the slurry onto the surface 74 with a swirl component of motion. In an alternative embodiment the stationary distribution device is adapted to accelerate the slurry prior to a distributor cup which then directs it onto the extended surface of the spray cup in a direction generally opposed to the general direction of the slurry sprayed into the gas.
Patent GB-2152490-A (GB)
Title: Mineral dewatering method
Inventor: CAWIEZEL KAY E
IPC: C09K23/42
Filed: 1985-01-04
Abstract: Nonionic surfactants based upon low molecular weight block copolymers of ethylene oxide and butylene oxide are particularly useful as low foaming dewatering aids in the processing (e.g., filtering, drying, etc.) of various mineral concentrates. Such surfactants are especially beneficial in that they exhibit a substantially reduced propensity to build up or accumulate in recirculating plant water. As result, such surfactants are particularly well suited for use in mineral processing facilities which are not equipped with the capability to treat recirculating plant water for the removal of excess surfactant accumulation therein.
Patent GB-2172403-A (GB)
Title: Method for operating automatic test equipment
Inventor: WILLIAMS LEWIS
IPC: G01R31/28
Filed: 1985-03-15
Abstract: In automatic equipment for the in-circuit testing of board mounting components, it is sometimes necessary to apply guard signals to circuit nodes other than nodes to which a device or gate under test is connected but with which there may be interaction. The invention provides a method for defining guards during the operation of automatic test equipment so that a selected component of a circuit may be tested which method includes the steps of establishing a measurement of the selected component (41) identifying a circuit node associated with the selected component (43), applying a guard to the node (44), establishing a measurement with the selected guard in place (46) and, should the guard result in an improvement, retaining the guard during subsequent automatic testing (48). Improvement may be assessed with respect to an initial unguarded measurement, with or without other guards in place. Those guards showing the greatest improvement may be retained and applied in combination for further improvement. The present invention avoids the need for a highly skilled operator to place guards manually, and also allows assessment of all potential guards which is not practical manually.
Patent GB-2157751-A (GB)
Title: Driven piling system
Inventor: KISS PAUL
IPC: E02D1/02
Filed: 1985-03-29
Abstract: The driven piling system facilitates the driving of a relatively inexpensive permanent casing. The casings 4,8, follow the annular hole created by a circular washer 10, which in turn is driven by a driving assembly 101. Energy is delivered to the driving assembly via pneumatic hammer 1 and the process is continued until no further penetration into the group is possible. Removal of the driving assembly allows soil testing through the central aperture in washer 10. A base is then formed at the end of the pile by withdrawing the driving assembly, introducing and driving a cement/sand mixture through the base of the pile 15, with the driving assembly. Concrete is then poured into the casing, and steel reinforcement may also be installed. <IMAGE>

Patent GB-2186293-A (GB)
Title: Magnetic thin film recording media
Inventor: WELLWOOD JANE
IPC: H01F41/14
Filed: 1986-02-11
Abstract: Magnetic thin films such as evaporated CoNi are generally prone to magnetic ageing whereby saturation magnetization, Ms, gradually decays with time by typically 3% over 1000 hours following deposition. This gradual decay may be overcome by artificially ageing the films. In the present invention a film, following deposition is placed in a chamber having a wet oxygen-rich atmosphere at room temperature for a few hours during which time Ms drops by typically 3%. The film is then removed from the chamber and will remain magnetically stable under normal atmospheric conditions. The wet oxygen-rich atmosphere may be provided by a source of pressurised oxygen which bubbles through a solution of sodium dichromate and into the chamber. Magnetic thin film tapes which had been artificially aged according to the invention were wear tested in a VHS video recorder and exhibited a markedly improved wear resistance.
