Patent GB-2049917-A (GB)
Title: A gas fitting, particularly for heating ovens and heating boilers
IPC: F23N5/10
Filed: 1980-05-02
Abstract: A gas fitting combines a pressure regulator and a solenoid valve which is arranged in series therewith and which acts as the adjusting member of an "on-off" regulator and which, when it opens, successively opens a throttled gas passage and a gas passage which is unthrottled relative to the gas passage through the regulator. The unthrottled gas passage is the regulating port (34) of the pressure regulator (30, 32, 34, 36) itself, the regulating member (32) of which pressure regulator is pressed, by a closure spring (39) opposing the force of a regulating spring (36), against a valve seat which surrounds the regulating port (34) or which is formed in the regulating port itself, the action of the closure spring (39) upon the regulating member (32) being cancelled as soon as the armature of the solenoid valve (27) has covered a predetermined partial stroke. As a result of this functional coupling of the pressure regulator (30, 32, 34, 36) to the solenoid valve (27), there is no need to provide a closure member on the solenoid valve (27) and the solenoid can be of smaller dimensions than in the case of the known embodiments. <IMAGE>

Title: Boundary layer control
Inventor: WALMSLEY SIDNEY
IPC: B64C21/00
Filed: 1981-10-07
Abstract: The invention claims to allow an aerofoil such as a wing to operate at large angles of attack for flight at low Reynolds Number, when the boundary layer is laminar, by adding a subsidiary aerofoil 4 outside the boundary layer at the point of normal boundary layer separation and using the downwash of the subsidiary aerofoil to prevent the boundary layer from separating. It also allows a flap 5 at the trailing edge of a wing to operate without boundary layer separation, whether the boundary layer is laminar or turbulent, by adding a subsidiary aerofoil 4 outside the boundary layer on the flap and using the downwash from the subsidiary aerofoil to prevent the boundary layer on the flap from separating. <IMAGE>

Title: >Liquid fuel burner
Inventor: JING-CHERNG JANG
IPC: F23D11/44
Filed: 1981-10-29
Abstract: A liquid fuel vaporizing burner suitable for burning kerosine comprises a burner body 1, an air uptake pipe 3 connected with the burner body, an U-shaped vapour duct 6 leading into the air intake pipe' an oil feed pipe 4 leading to the air intake pipe and an electric heating tube 5 adjacent the oil feed pipe.

Patent GB-2129592-A (GB)
Title: Motion sensor
Inventor: COLEMAN PAUL
IPC: G08B13/14
Filed: 1982-07-02
Abstract: A small, compact motion sensing device suitable for use as a portable alarm system comprises a piezo-electric bar which is mounted with a small weight so as to provide an output voltage when disturbed in any way. The output is amplified using a field effect transistor with an unusually large source resistor thus requiring a very small operating current. When triggered a piezo-electric buzzer driven by a transistor, coil and diode arrangement ensures high electrical energy to sound energy conversion. The sensitivity is adjustable over a very wide range using a potentiometer which does not affect the low power consumption. Time delays and an automatic reset can be incorporated for greater convenience of operation. The system can also be used to control other external alarms and devices.
