Patent GB-2051132-A (GB)
Title: Alloy Powder for Dental Amalgams
IPC: A61K6/847
Filed: 1980-05-16
Abstract: The powder contains particles comprising a core which contains a minor proportion of silver, and a peripheral layer of a silver-tin alloy surrounding the core. The use of a core containing a minor proportion of silver enables the particles overall to have a low silver content. The powder may be formed by coating the metals on to the core particles and then alloying e.g. by entraining the particles in a stream of inert carrier gas containing the particles through a heating zone so as to melt the surface stratum and then cooling. It has been found that the powders can be used to form dental amalgams with properties comparable to amalgams produced with conventional alloys containing comparatively high amounts of silver.

Title: Sterilizer control cycles.
IPC: G05B19/16
Filed: 1980-06-04
Abstract: A sterilizer user customizes basic sterilizing cycles to his needs by the use of a switch matrix (148). The selected customizing information is transferred by a microprocessor (140) of an electronic controller (36) to a buffer store (146) from where it is transferred by a writer/ reader (152/154) to a magnetic stripe on a card (302). The information is thereby automatically stored in permanent, machine-retrievable form. In operation, the electronic controller (36) combines the information stored on the card with a program for a basic sterilizer cycle stored in a memory (144). The number of customized cycles which can be established by the use is not limited by the memory capacity of the controller and provision can be made for security of customized cycles. <IMAGE>

Patent GB-2074000-A (GB)
Title: Resistance heating elements
IPC: H05B3/62
Filed: 1981-03-24
Abstract: The use of electrical resistance heating in pottery kilns hitherto has been inhibited by firstly the need to provide door interlock safety devices and secondly the inability to effect reduction firing without damaging the resistance heaters. The object of the invention is to provide resistance heating means suitable for kilns avoiding these disadvantages, this objective being met in a construction comprising an impervious ceramic tube (1) through which a resistance heating element (12) passes leaving the bore of the tube free for the passage of cooling air. The bore of the tube may be closed during heating by a plug (17). <IMAGE>

Title: Fire fighting equipment
IPC: E21B35/00
Filed: 1981-04-10
Abstract: A fire fighting tower is intended to be mounted on a floating vessel for fighting a fire on an offshore production platform and comprises an access tower having a gangway (30) to enable personnel to be moved to the vicinity of the mouth of the well. Not all drilling platforms are of the same height and the desired height of the access tower will vary with the tide.

Title: Turbine disc hub cooling means of a gas turbine engine
Inventor: BENFIELD BRIAN HENRY
IPC: F01D5/08
Filed: 1981-12-22
Abstract: A rotor disc (15) has an axially enlarged hub portion (18) with a bore (20) through which a turbine shaft (19) extends in coaxial, radially spaced apart relationship. The hub portion (18) is provided with an annular open channel (22) in the bore (20) and an annular deflector (23) fixed on the turbine shaft (19) ensures that at least part of an axial temperature regulating air flow along the annular gap (24) between the turbine disc (15) and the turbine shaft (19) is deflected into the open channel (22).

Title: Rotary positive-displacement fluid-machines
Inventor: SCAPECCHI PIER LUIGI
IPC: F04C27/00

Patent GB-2122339-A (GB)
Title: Infra-red intrusion detector system
Inventor: BLOICE JOHN ANTHONY
IPC: G08B13/19
Filed: 1983-06-24
Abstract: An infra-red intrusion detector system comprises an optical system 13 having a plurality of fresnel lenses in a substantially D-shaped array to direct infra-red radiation onto a detector element which is movable so as to alter its field of view. The field of view of the optical system 13 is greater than that of the detector element and thus all of the fresnel lenses are never in use at the same time and an intruder cannot determine by visual inspection the field of view of the detector system. The detector circuitry includes a bi-lateral switch which uses two oscillators which are either free to run or are inhibited according to the state of two detector outputs which are respectively high and low or vice versa for normal and alarm conditions. Respective transistors are turned on by the rectified output of the oscillators to provide normally open and normally closed switched paths. In addition, several detector systems each comprising an arrangement of four pyroelectric detector elements linked together are described. <IMAGE>
