Title: Improvements relating to electronmultiplier tubes
IPC: H01J43/18
Filed: 1980-04-24
Abstract: A method of manufacturing an electronmultiplier tube includes the use of an electrically conductive assembly comprising a group of strip like, side-by-side conductors maintained in a predetermined, geometrical format, the conductors being mutually spaced by means of at least one removeable interlinking members 14-17 extending transversely of the group.

Title: Switching inductive loads
IPC: H03K17/64
Filed: 1980-05-12
Abstract: A transistor switching circuit for switching current from a d.c. supply to an inductive load ZL comprises a switching transistor T in series with the load and a series connected diode D1 and capacitor C1 connected across the transistor in order to absorb the inductive energy of the load during transistor off periods. When the transistor T switches on, the charge stored in capacitor C1 is transferred, via a diode D3, to a capacitor C2 whereafter it is transferred back into the d.c. supply via diode D4 which becomes forward biassed during the succeeding transistor off period. In a further embodiment, energy stored in capacitor C2 is transferred to a base drive power supply for transistor T, rather than back to the d.c. supply. <IMAGE>

Title: Thermal systems
IPC: G01K5/32
Filed: 1980-10-02
Abstract: A thermally-responsive sealed system comprises a cylindrical phial secured to an expansible capsule by a length of capillary tube.

Title: Drill pipe tester valve
IPC: E21B47/10
Filed: 1981-04-03
Abstract: A drill pipe tester valve for installation in a pipe string has a housing having a first end adapted to be connected to a well test string, which housing has a flow passage (90) therethrough. A spherical valve member (92) is disposed in the flow passage of the housing. Lugs (118) are provided for engaging the spherical valve member and rotating the spherical valve member between open and closed positions wherein the flow passage of the housing is open and closed, respectively, as the spherical valve member is moved axially relative to the housing. A lower valve member seat structure (130) has a downward facing surface (132) supportably engaged by an upward facing surface (134) of the housing when the spherical valve member is in its said closed position. This permits downward forces exerted upon the spherical valve member in its said closed position due to fluid pressure in the well test string of drill pipe above the spherical valve member, to be transmitted substantially entirely to the housing through the engagement of the downward facing surface of the lower valve seat structure and the upward facing surface of the housing. <IMAGE>

Patent GB-2077139-A (GB)
Title: The separation of particulate material from a stream of gas
IPC: B01D46/46
Filed: 1981-06-08
Abstract: Powder, such as plastics granules being delivered to a moulding machine, is transported in a stream of air to enter a body (10) tangentially between baffles (12) and (13). Most of the powder drops into a funnel (29) mounted on a pivoted arm (31) biased upwards by a spring. The air, carrying some powder, rises and escapes through a frusto-conical filter (25) made of flexible material with pores too fine to allow the powder to pass through it. The top of the filter is closed by a disk (26) of similar filter material having a weight (28) at its centre. When the funnel is weighed down with material unable to escape from it, its movement actuates a valve which causes the flow of air to cease, whereupon the weight (28) causes the filter (25) to turn inside out, thus freeing from the filter powder which would otherwise clog the filter. After a predetermined time the flow of air starts again, causing the filter to return to its original shape. Filter (25) is enclosed by a fixed downstream filter (20). Both filters are backed by cages (16, 19). <IMAGE>

Title: Anti-rotation lock
Inventor: POOLE HORACE
IPC: F02K1/72
Filed: 1982-03-06
Abstract: In a gas turbine engine thrust reverser of the kind where one cowl portion separates axially from another to create a gap it is possible for air loads in the cowl inner and outer surfaces, to move the cowl portion to open the gap, at times other than those when the gap is required. The most likely time for this to happen is if connection is lost between the actuation motor and ballscrew (24). The pull of the cowl portion on the ball screw (24) is sufficient to rotate it. Three gears (36, 38, 40) are arranged, one to be driven by the ball screw (24) the other two freely rotatable and all engageable to create opposing loads and so lock the ballscrew (24) against rotation. Locking engagement may be brought about by a solenoid actuator (46). <IMAGE>
