Title: Helicopter airspeed measuring system
Inventor: CLELFORD DOUGLAS HAROLD
IPC: G05D1/00
Filed: 1984-01-17
Abstract: The specification is substantially identical to that of Patent Specification GB 2081474A but the claims are directed to apparatus for providing an aircraft air speed signal (10) derived from a Pilot Static sensor (12) and a longitudinal accelerometer (14) as shown in Fig. 1. The provision of integrators (15), (19) and amplifier (20) eliminates short-term variations in airspeed signal from the sensor (12) which might arise from wind gusts and turbulence. Changes in inertial speed in the short term are however sensed by accelerometer (14). <IMAGE>

Title: Porous metal structures made by thermal spraying fugitive material and metal
Inventor: EATON HARRY EDWIN
IPC: C23C4/04
Filed: 1984-12-19
Abstract: Porous metal deposits especially useful in gas turbine engines as compressor seals are made by thermal spraying a metal powder and a meltable polymer powder mixture, wherein the spraying process and a subsequent polymer removal process are chosen to produce less than 30 weight percent oxide. Oxide contents of 4-25% are typical. When 86 weight percent nichrome is sprayed with 14 weight percent polymethylmethacrylate the polymer is removed by heating in air to about 315 DEG C. The resultant porous structure will have an oxide content of 7% and an apparent density of about 32%. A meltable polymer additionally produces a more desirable pore structure.

Title: Adjustment of the volume of scavenging and/or froth removing devices of can filling and closing plants
Inventor: POLITT HANS-DIETRICH
IPC: B65B31/04
Filed: 1986-04-11
Abstract: An arrangement is proposed for the capacity-dependent adjustment of the gas volume which is supplied to the nozzles of a gas-supplying device disposed beneath the lid and/or to the outlet means of froth destroying members of can filling and closing plants. An initial pressure is ensured for the gas, such as CO2, which is used for the gas supply and such pressure is independent, even with variable capacities of the machine. Since the required quantity of gas can vary, depending on various factors, a control pressure is produced in a control medium and influences pressure regulators in the feed circuit of the gas-supplying nozzles, so that the gas pressure is set to a pressure which is proportional to the control pressure. In addition, this control pressure is converted into an electrical control signal which is adjustable in accordance with variable desired values and directly controls the capacity of the plant by influencing the r.p.m. of the main drive motor. This electrical control signal, which is proportional to the control pressure, is also used to change the control pressure via the intermediary of prescribed desired values. In this manner, the gas requirement is set according to the conditions and limited to the necessary extent.

Title: Tamper-proof enclosures
Inventor: CLARK DAVID
IPC: G08B13/06
Filed: 1986-04-21
Abstract: A tamper-proof enclosure 10 for a burglar alarm bell 24 has four layers 14, 16, 18, 20 of material disposed inside an outer casing 12. Two layers 14, 18 are electrically conductive and connected to an electric circuit (not shown) such that when these two layers 14, 18 are in contact an alarm is operated.

A framework 28 of metal spikes 30, 32, 34, 36, 38, 40, 42, 44 project from a base plate 26 and surrounds an alarm bell mechanism 24 of conventional design. If pressure is applied to the outer casing 12 the layers of material 14, 16, 18, 20 are punctured by one or more of the spikes, the electric circuit is completed and the alarm operated. If a heat source (not shown) or acid is used the insulating layers 16, 20 are destroyed and the circuit completed also operating the alarm. <IMAGE>
Patent GB-2191815-A (GB)
Title: Closing device for doors
Inventor: WILLIAMS PATRICK YELVERTON
IPC: E05F1/02
Filed: 1986-06-04
Abstract: The closing device has an upright tube (1) closed at the bottom by a plug (2) and containing a damping liquid (10), and a sinker weight (3) arranged in the tube and connected to a flexible cord (5) which extends out of the top of the tube for connection to a door so that the door is automatically closed when released, the sinker weight (3) falling under gravity to pull the door closed. The device includes a passage (3b) extending through the sinker weight with a valve seat (3a) formed at the lower end of the passage and co- operating with a buoyant self-seating valve member (7) (preferably a plastic ball which is not captive relative to the weight) which controls liquid flow through the passage when the weight sinks. As the door is opened, the weight (3) is pulled rapidly upwards and lifts off the buoyant valve member (7). Preferably, the valve member (7) substantially seals the passage (3b) in the weight and there is a clearance around the weight for passage of the damping liquid during closing of the door. <IMAGE>
