Title: Radar device
Inventor: MOREY REXFORD MOREY
IPC: G01S13/88
Filed: 1984-10-19
Abstract: A geophysical radar system comprising a transmitter, a receiver and a display unit, all controlled and synchronized by a controller, the system producing long, high powered, coherent pulses each with a large swept bandwidth with a high frequency which is at least five times the low frequency, the pulses being sent by the transmitter into a medium and used by the transmitter to generate a digital reference signal, and the long reflected pulses being detected by the receiver and used to generate a digital reflected pulse signal which the controller cross-correlates over a series of times with the reference signal to produce a recording of the medium, the system having high resolution, considerable detection range, and the ability to operate in real time.

Title: Furniture anchorages
Inventor: UNWIN CECIL NORMAN
IPC: B60N2/015
Filed: 1985-01-03
Abstract: Furniture, particularly seats, is often anchored but adjustable or removable in vehicles e.g. aircraft. The floor is provided with parallel rails (13) with which elements (10, 11) at the base of the seat can engage at selected longitudinal positions. Each rail has a series of detents (16) into which the seat elements can be lowered, and then moved longitudinally to engage below an undercut formation in the rail. A catch device (6) locks into one of the detents when such engagement is attained to prevent further longitudinal movement, thus securing the seat. Said catch device is preferably a spring-loaded plunger. <IMAGE>

Patent GB-2187445-A (GB)
Title: Treatment of gas stream comprising H2S
Inventor: WATSON RICHARD WILLIAM
IPC: B01D53/52
Filed: 1987-01-30
Abstract: A feed gas stream containing at least 60% by volume of hydrogen sulphide is burnt in a first combustion region 2 to form water vapour and sulphur dioxide. Oxygen (preferably pure) is employed to support combustion in the region. Thermal reaction then takes place in thermal reaction region 10 between hydrogen sulphide and sulphur dioxide to form sulphur vapour and water vapour. The resulting gas mixture is then cooled in a waste heat boiler 12 and sulphur vapour is extracted in a condenser 14. The gas mixture then passes into a second combustion region 16 in which a further portion of the hydrogen sulphide is burnt in the presence of oxygen to form further sulphur dioxide and to adjust the mole ratio of hydrogen sulphide to sulphur dioxide to about 2:1. Further reaction between hydrogen sulphide and sulphur dioxide may be conducted in a thermal reaction region 22 and in catalytic reactors 26 and 32 with further sulphur extraction in condensers 28 and 34. The mole ratio of hydrogen sulphide to oxygen entering the combustion region 2 per unit time is greater than 2:1 and the mole ratio of hydrogen sulphide to fluid(s) (if any) other than oxygen being introduced into the region 2 is greater than 3:2 and preferably greater than 4:1. By using substantially pure oxygen to support combustion of the hydrogen sulphide, a relatively large flow rate of feed gas mixture may be handled in a plant of given size. <IMAGE>

Title: Powered hammer
Inventor: COLEY JOHN
IPC: B21J7/46
Filed: 1987-02-26
Abstract: A powered hammer comprises a reciprocatable hammer head 12 in the form of a piston movable in a cylinder 14 under the influence of driving fluid. A change-over valve 16 directs fluid to the faces of the piston to drive the head along a hammer stroke or a return stroke. Towards the end of the return stroke, the piston closes a vent 74 to cause pressure to build up within chamber 72. This is communicated along passage 18 to the valve 16, which changes over to initiate the next hammer stroke. <IMAGE>
Patent GB-2207812-A (GB)
Title: Electromagnetic actuators
Inventor: WYGNANSKI WLADYSLAW
IPC: G01B7/00
Filed: 1987-08-07
Abstract: The movement of a slider along a track 16 (eg for use in audio or lighting equipment) is controlled by a magnetic coil 18 which is disposed parallel to the track and is connected to a control unit 24 for supplying d.c. current to the coil. The slider comprises a permanent magnet 12, whereby the resultant magnetic interaction with the coil 18 causes the slider to move at a desired speed to any position along the track which may be programmed into a memory of the control unit. A position sensor 14 cooperates with a track 28 to feedback position data to the control unit 24. <IMAGE>
Patent GB-2204357-A (GB)
Title: I. C. engine fuel injection nozzle

IPC: F02M45/08
Filed: 1988-03-31
Abstract: The fuel pressure operated valve member 15 carries in a bore 20, a slidable flow restricting pin 21 which is biased into engagement with a portion of the seating 12. The flow restricting pin 21 and/or said portion of the seating define grooves 30 and the arrangement is such that when the valve member is first lifted from the seating fuel flow through the outlets takes place at a restricted rate due to the grooves but when the valve member is lifted further the flow restricting pin is also lifted from the seating to allow unrestricted flow of fuel. <IMAGE>

Title: Sampling clock synchronisation
Inventor: KAO MING-LUH
IPC: H04J3/06
Filed: 1988-05-05
Abstract: An apparatus for compensating for differences in the rate of two clocks includes a transmitter 18 for transmitting samples of voice synchronized to a first clock (CLKA) and a receiver 22 for receiving samples synchronized to a second clock 54. A slip detector 50 determines when a slip has occurred between the two clocks. An intelligent expander 52 discards or duplicates voice samples to account for the slippage. The slip detector (Fig 3) stores representations in latches (72, 74) corresponding to the maximum and minimum pulse widths which occur in the logical product (CLKA CLK2 Fig 4) of the two clocks, and on the basis of these decides when each cycle of a difference between the clocks occurs. Microprocessor interrupted routines, (Figs 5A, 5B) are used. A derived slip error (Fig 6) may control a VCO. <IMAGE>

Title: Commercial vehicle superstructure de-mounting/re-mounting apparatus
Inventor: TINSDALE FRANK
IPC: B60P1/64
Filed: 1988-07-18
Abstract: In order to lift and remove superstructure 70 from chassis 80 of a vehicle 50, the vehicle 50 is reversed between spaced apart pairs of rails, forming a first part of the apparatus of the invention, after the superstructure 70 has been detached from the chassis 80, its rear wheels ascending portion 26 of a collapsible ramp raised at an angle to an adjustable floor unit mounted between the rails.
