Patent GB-2126721-A (GB)
Title: Borehole surveying
Inventor: RUSSELL ANTHONY WILLIAM
IPC: E21B47/022
Filed: 1983-08-22
Abstract: A survey instrument is positioned at the mouth of a borehole and determines the initial components of gravity with respect to the survey instrument by means of a gravity sensor unit 24. The rates of rotation about three non-coplanar axes are then sensed at a series of locations along the length of the borehole by means of three-axis rate gyroscope unit 12. The position of the borehole at each measuring location is then calculated by determining the initial set of direction cosines from the sensed gravity components and an initial value of the azimuth angle and incrementing these values using the rates of rotation sensed by the rate gyroscope unit 12 to obtain the sets of direction cosines at subsequent measuring locations. <IMAGE>

Patent GB-2137651-A (GB)
Title: Coated abrasives
Inventor: ROLFE A G
IPC: C09K3/14
Filed: 1984-03-22
Abstract: A coated abrasive article comprises a support member and, bonded to the support member, both sintered hard metal carbide particles and particles of another abrasive.

Patent GB-2156230-A (GB)
Title: Self-returning toy vehicle
Inventor: CROSMAN DORLAND L
IPC: A63H17/40
Filed: 1984-03-28
Abstract: A toy vehicle which when propelled by a player from a starting point along a flat surface in the forward direction, acts to store energy, the vehicle at the end of its forward run being caused by the stored energy to reverse its orientation as it runs back toward the starting point. The vehicle includes a chassis having a front cowl section 11 projecting therefrom below which is a front wheel carriage 20 coupled to the cowl by a pivot pin, whereby the carriage orientation is reversible relative to the cowl. The carriage has a spring motor therein operatively coupled to the front wheel axle which when rotated during the forward run of the vehicle acts to wind the motor. The rear wheel axle is supported in bearings below the rear section of the chassis, one 17 of which is slotted to permit angular displacement of the axle. At the end of the forward run, the energized motor then acts to drive the front wheel carriage in the reverse direction to cause angular displacement of the rear axle, as a result of which the chassis swings in an arc (Figs 9A-9E) to assume a position behind the front wheel carriage as it returns toward the starting point. <IMAGE>

Title: Transient Signal Detector
Inventor: DIXON MICHAEL
IPC: H03K17/18
Filed: 1984-04-12
Abstract: A transient signal detector for liquid crystal touch switches 17 and 18 comprises a bridge circuit 26 incorporating the switches 17 and 18, and a phase sensitive detector 28 to detect bridge imbalance. Imbalance signals are fed to a band-pass filter 35, and thence to threshold detector circuit 40 to 58 and subsequent non- retriggerable monostable 60. Pressing of a touch switch 17 or 18 produces transient bridge imbalance which is detected and filtered, and which triggers the monostable 60 if the threshold of circuit 40 to 58 is exceeded. After triggering, the monostable (d) is unresponsive for a period corresponding to its internal time constant. This desensitises the detector to switch release, and the threshold detector 40 to 58 desensitises the detector to other unwanted signals. <IMAGE>

Title: Combined telecommunications and data communications systems
Inventor: MIDDLETON FRANCISCO AUTURO
IPC: H04M11/06
Filed: 1985-03-20
Abstract: A combined telecommunications and data communications system operates by partitioning data wherein the PCM speech transmission data field is used to contain both digitised speech and other data in the same channel within a frame. Thus the system enables speech and data to be combined in a common information field and to be simultaneously transmitted in the same channel, frame by frame, through a digital switching network (24). The switching network contains a common port which has a digital interface (210) connected to the port which digital interface can separate and combine the speech and the data fields. The digital interface is connected to a conference module (262) which conference module receives the speech fields via a speech bus (258). The digital interface is further connected to a data base system (208) which data base system receives the separated data fields via a data tone bus (260). <IMAGE>

Abstract: 850,750. Respiratory measurements. JAEGER, E. April 8, 1958 [April 15, 1957], No. 11044/58. Class 81(2) [Also in Group XXIX] Apparatus for measuring the flow resistance of body respiratory passages comprises two flow resistances connected in series in a conduit and a valve connecting the conduit with atmosphere between the resistances, the total flow resistance being varied periodically by opening and closing the valve, pressure variations thus created being used to determine the respiratory passage flow resistance. A tube 12 having axial slots has at each end a cap 10, 11 in which is mounted a flow resistance 2, 3 comprising a perforated screen. An inlet 1 and an outlet through which air passes from the lungs, are provided in each cap respectively. The tube 12 is surrounded by a tube 13 having corresponding axial slots and rotatable by an electromagnet so that the slots in the tubes 12,13 may be brought into or out of register thus forming the valve. Heaters 18 surround one or both resistances 2, 3. A threeway cock connects a pressure measuring device either to a chamber 8 on the upstream side of the first flow resistance 2 or to atmosphere as required. In operation, respiratory air is directed through the flow resistances 2, 3, and the valve is closed periodically for a short time, the pressure in the chamber 8 being recorded just before and just after each closing of the valve. The threeway cock is actuated electromagnetically to connect the pressure measuring device with the chamber 8 just before the valve is closed. The cock comprises a valve member 25 movable by a spring 27 to connect the chamber 8 with the pressure measuring device through a passage 25b and movable in the opposite direction by an electromagnet 28 to connect the presure measuring device to atmosphere through a passage 25a.

Patent GB-2162299-A (GB)
Title: Refrigeration method and apparatus
Inventor: MARSHALL JOHN
IPC: F25J1/02
Filed: 1985-07-23
Abstract: A stream of permanent gas such as nitrogen at elevated pressure is cooled to below its critical temperature by heat exchange with work-expanded working fluid. The stream 2 is then further cooled in heat exchanger 4 and successfully flashed through at least three expansion valves 6, 12 and 16. Resulting flash gas is separated from liquid gas in separators 10, 14 and 18 respectively. The flash gas is passed through the heat exchanger 4 to provide cooling for such heat exchanger. By performing at three such successive isenthalpic expansions instead of the conventional one or two expansions, greater thermodynamic efficiency can be achieved enabling more favourable conditions to be set for the work expansion of the working fluid.
