Title: Flexible rudder
IPC: B63H25/38
Filed: 1978-09-25
Abstract: A rudder for watercraft, particularly propeller-driven craft, has a flexible rudder plate which is elastically stretchable because the rudder plate is formed by a flexible plate of an elastically stretchable material which is of an elasticity that permits a deflection of the plate by the action of the water flowing past it, and/or because the rudder plate has its ends, which follow upon each other in the direction of propulsion of the craft, yieldably urged in a direction away from each other. The flexible plate is made of an elastomer such as rubber or rubber-like plastic and may be perforated, leaving flexible flaps in the perforations.

Title: Separating oxygen and nitrogen from air by adsorption
IPC: C01B21/04
Filed: 1978-11-09
Abstract: Apparatus for separating oxygen and nitrogen from air comprises a plurality of vessels 1-8 containing molecular sieve, a rotary valve 9, an air supply line 34 connected to the rotary valve, means for directing air from the rotary valve to at least first and second of said vessels arranged in series, and means for rotating the rotary valve so that, in use, the molecular sieve in the first vessel is saturated and the molecular sieve in the second vessel is unsaturated when the rotary valve moves to direct air through the second and third vessels in series. Each molecular sieve bed is consequently used until fully saturated. The rotary valve 9 may also connect the saturated beds sequentially with a line 35 carrying flushing nitrogen, a first suction line 36, a second suction line 37 effective to produce a lower pressure than the first suction line, and a product repressurising line 45. <IMAGE>

Title: Liquid Methylene Urea Fertilizers
IPC: C05G5/23
Filed: 1979-06-18
Abstract: Liquid methylene urea fertilizers comprising aqueous mono-, di-, and trimethylene ureas which provide an efficient source of nitrogen for direct application to the foliage of commercial crops or lawn turfs without the hazard of foliage burn.

Title: Ignition arrangement for thyristors, triacs or the like
IPC: H03K17/97
Filed: 1981-03-04
Abstract: The ignition pulse for a thyristor (5) is produced by induction in that, at the position of a bistable magnetic element (1), a variable, reversible magnetic field is created, for example by movable permanent magnets (4) connected to a movable machine part. The field reversal causes an abrupt change in direction of magnetisation in element (1), which change induces in winding (2) a voltage pulse for said ignition. Bistable Wiegand wires and multi-layer elements are described for magnetic element (1). Variations include a movable BME or ferromagnetic object. Phase displacement may be controlled by a second DC Winding (Fig. 2, not shown) or setting magnet (3) may be made movable or its coupling controlled by a displaceable ferromagnetic tongue. Rotary as well as linearly moving permanent magnets are described and asymmetrical and symmetrical excitation of the BME considered. <IMAGE>

Title: Gas-fired water heater
IPC: F24H1/26
Filed: 1981-05-08
Abstract: In a gas-fired balanced-flue water-storage heater, a transversely extending air baffle (56) depends from a water jacket skirt end wall (22) between a combustion-air chamber (44) and a burner chamber (24). Exhaust gases from a liquefied petroleum gas burner (26) enter an exhaust or heater chamber (32) and are discharged via an exhaust pipe (38) which passes through the combustion-air chamber (44). The latter receives combustion air from an inlet pipe (48) coaxial with exhaust pipe (38). A corrugated sheet metal baffle (34) in the exhaust chamber (32) rapidly heats up on ignition of the burner main flame to promote air flow by convection and avoid vitiation. The baffle assembly (53) mounted on a telescopic extension (38a) to the exhaust pipe (38) can be retracted into a sleeve (23) when the heater is not in use - an advantage when the heater is installed in a mobile home. <IMAGE>

Title: Fluid flow couplings
Inventor: BRAKE ARTHUR LEIGHTON
IPC: F16L37/23
Filed: 1981-12-16
Abstract: A fluid flow coupling, particularly for pneumatic lines, comprising a first element (3) and a second element (31) each of which contains a valve retracting member (13, 36) having a flange which engages a spring-loaded valve member (16, 38) which, when the two elements are interengaged, abut each other to provide a through- flow path through the coupling. When the path is open the two valve retracting members engage to close a venting path (74) which is opened when the two elements come to be separated. The two elements are held together by balls (46) engaging in a groove (22) and held therein by a sleeve (47) which carries a second sleeve member (56) having teeth (61) which engage with teeth (62) on a sleeve member (23) carried on the element (3). When the teeth are engaged the coupling can only be moved towards the engaged condition and to release the coupling it is first necessary positively to manually draw back the sleeve (56) to disengage the ratchet teeth. It is thus not possible to disconnect the coupling inadvertently and it is not possible to disconnect the coupling when the space between the two halves of the coupling contains fluid under pressure. <IMAGE>
