Title: Device for reducing squall loads on aircraft wings
Inventor: KLUG HEINZ GUNTER
IPC: B64C13/16
Filed: 1983-10-07
Abstract: In an aircraft having airfoil wings 10 provided with flaps or passages, there are provided, over the outer portion 10c of the wing 10, slot-like narrow flow channels 11 from the underside to the upper side of the wing structure 10, so arranged and designed that the gust lift is nullified, such channels being controlled by respective flaps 12.

Title: Electrical connectors
Inventor: MARSHALL BRIAN HAROLD
IPC: H05K3/22
Filed: 1983-11-17
Abstract: To make an electrical connection, a resilient (for example rubber) sleeve 16 is slipped over a stud 14 and a conductor wire 18 is then inserted between the sleeve and the stud. The resilience of the sleeve presses the wire against the stud to make a connection. A number of conductor wires can be connected to one stud, and these to each other, in this way. Some studs can be inserted in holes 12 in the base board 10, and simple electrical circuits can be built up by connecting components between appropriate studs to obtain the desired circuit configuration. <IMAGE>
Patent GB-2133097-A (GB)
Title: Pneumatic brake valve
Inventor: COUPLAND RALPH M
IPC: B60T15/04
Filed: 1983-11-25
Abstract: A control valve of the kind in which an input effort A is applied via a graduating spring 16 to a reaction piston 10 controlling one or more inlet/exhaust valve assemblies 12/14/40 delivering a maximum pressure lower than system pressure, has abutment means or the like by which the input effort is transmitted to the reaction piston when the load in the graduating spring exceeds the effort normally required to achieve the maximum pressure. Such "push-through" which enables the input effort to be increased sufficiently to free a jammed reaction piston, occurs when the guide piston 17 engages the spring seat 54 (Fig. 1), or interposed shims 52 (Fig. 3) in the dual concentric brake valve described, when sufficient input travel remains available on push-through before the guide piston 17 engages shim 50 on the casing top to operate the inlet/exhaust valve assembly so that the desired maximum delivery pressure can be achieved. <IMAGE>

Title: Improvements in or relating to radio communication apparatus and systems
Inventor: GIGER ADOLF JOSEF
IPC: H04B7/005
Filed: 1983-12-09
Abstract: In a radio communication system, an adaptive transmitter power control system is described wherein the signal level at each receiver is monitored and a control signal, which is a function of the signal level, is transmitted back to the transmitting station to adjust the transmitter output power, as required. By transmitting the lowest power level consistent with system objectives, the repeater circuits operate in a highly linear mode, and cochannel interference is significantly reduced.

Title: Non-peroxide trivalent chromium passivation
Inventor: CROTTY DAVID E
IPC: C23C22/53
Filed: 1984-07-02
Abstract: An aqueous acidic peroxide-free solution for treating receptive metal surfaces to impart a chromium passivate film thereon contains trivalent chromium ions, hydrogen ions to provide a pH of 1.2 to 2.5, nitrate ions as the essential oxidizing agent to activate the hydrated trivalent chromium to form a chromate film on the substrate, and iron, cobalt, nickel, molybdenum, manganese, aluminium, lanthanum and/or cerium ions to activate the formation of the chromate passivate film. The use of peroxide as an oxidizing agent is avoided, as are its accompanying problems such as high consumption of oxidizing agent and rapid loss. The aqueous acidic solution can also contain sulphate ions, halide ions, organic carboxylic acid, a silicate compound, and a wetting agent.

Title: A thermocouple device
Inventor: HEHL KARL
IPC: G01K1/16
Filed: 1984-08-13
Abstract: The ends of the wires (13a', 13b'), which serve as a thermo pair of a thermocouple, are enclosed by a heat-resistant sleeve (16), and are fused to form a mixed metal body (13m).This mixed metal body (13m) is axially pressed into a recess (21) provided in a heat-conducting plate member (17). The heat-conducting plate member (17) protrudes beyond the end of the sleeve (16) and the end face of said plate member (17) is in thermal contact with a metallic heat-conducting housing (18) which axially holds together the sleeve (16) and the heat-conducting plate (17).

Patent GB-2145854-A (GB)
Title: Voltage regulator
Inventor: GLENNON TIMOTHY F
IPC: H02J3/46
Filed: 1984-08-31
Abstract: An engine driven multi-phase generator has a control unit which incorporates a programmed microprocessor to control generator operation. A generator voltage regulator utilizes the microprocessor of the generator control unit to develop an average phase output voltage error which is added 97 to the average phase voltage of the generator, and used for controlling the generator field current. In the event of a phase failure the generator control unit senses an abnormally high phase voltage condition, and disables the average phase voltage circuit by opening a switch 115. In the event of an abnormal difference between high and low phase voltages, the gain of the error signal circuit is reduced by opening a switch 114 in parallel with a resistor 131. <IMAGE>

Title: An automative vehicle equipped with at least four road wheels and having a short turning radius
Inventor: BLAIZE JACK
IPC: B62D61/12
Filed: 1987-08-28
Abstract: An automotive vehicle having a short turning radius and equipped with a conventional frame (2) is provided with two front steerable road wheels (3) and two rear drive wheels as well as an additional steerable wheel (6) which is orientable by means of a hydraulically actuated steering mechanism (13). The additional steerable wheel can be turned through a substantial turning angle on each side of a longitudinal median position and is also mounted as to be capable of vertical displacement with respect of the vehicle frame.
