Patent GB-2052002-A (GB)
Title: Servo actuator for vehicle clutch
IPC: F16D48/06
Filed: 1980-06-26
Abstract: A servo-actuator (1) allows actuation of a clutch by pedal (64) or in response to a gear change. Depression of the pedal causes pressurisation of chamber (11) via follow-up valve assembly (4, 56-61) whereby piston (14) drives piston (20) against spring (21) to displace fluid from master cylinder (33) to disengage the clutch. Subsequent release of the pedal allows the valve assembly to vent chamber (11) to a blow-off chamber (22) having an outlet port fitted with a filter (47). The gear lever is fitted with a switch in series with a switch actuated by the pedal (64) so that, when the pedal is in its released position, actuation of the gear lever energizes a solenoid valve which then directs air to chamber (15) to depress piston (20) and disengage the clutch. The solenoid valve when deenergized vents chamber (15) via an expansion chamber and throttle designed to provide controlled reengagement of the clutch. <IMAGE>

Title: Bags and containers with interior lamps
IPC: A45C15/06
Filed: 1980-09-09
Abstract: A handbag has a lamp (24) disposed in its interior. A switch (22) in the body of the bag is operative so that when the bag is closed the lamp (24) is switched off but when the bag is opened the lamp is automatically switched on so as to illuminate the interior (26) of the bag. The switch (22) illustrated is a reed relay which, when the bag is closed, is held in an open state by the presence of a permanent magnet (30) contained in the flap (14) of the bag. The relay closes when the magnet (30) is moved away from the relay upon the bag being opened. Possible alternative switches can be mechanical or electronic. A light sensing device can be incorporated into the bag to prevent switching on of the lamp when the ambient light is above a predetermined level. <IMAGE>

Title: Culture-collecting kit and a method of taking a culture sample utilising it
IPC: C12M1/30
Filed: 1980-09-26
Abstract: A culture-collecting kit comprises a sterile film package (12) with two compartments divided by a rupturable seal (26). The first compartment (34) contains a growth medium (40A). The second compartment (36) contains a swab (42) having a collecting head (46) at the end of a stick (44) formed with a weakening (48). The compartment (36) has two pairs of transversely aligned notches (38-38; 40-40) and an end sealed by a peelable seal (20). In use, the seal (20) is unpeeled, the swap (42) is removed and a culture sample is taken. The package (12) is torn across the notches (38-38) and the swab (42) is re-inserted into the rest of the package so that the head (46) penetrates through the seal (26) into the growth medium (40A). The handled, contaminated stick portion is broken off at the weakening (48) and the package (12) is resealed by an identification label (58). The package (12) is now ready for transfer to a laboratory. There, the package (12) is opened by tearing it at the notches (40-40). The labelled portion of the package (12) can be used as a handle for gripping the stick (44) and the rest of the package is discarded to expose the head (46) for testing. <IMAGE>

Patent GB-2100686-A (GB)
Title: Trailer stabilizers
Inventor: CHIGART
IPC: B60D1/32
Filed: 1981-06-18
Abstract: A caravan stabilizer comprises two additional front wheels joined to the caravan by way of a rotary turning plate carrying a coupling ball and sliding bars which allow the working of the inertia-brake of the caravan. With a stabilizer pole pivotally connected to the turning plate, it does not transmit any weight or pitching movement of the caravan to the car. Most of the swinging effect is stopped by the inertia of the stabilizer, by its suspension and by the reaction of its wheels on the ground (wheel axis set behind turning axis of rotary turning plate). The possible remaining swaying is stopped by a device consisting in the reaction of springs against a bar fixed at the rear of the car. <IMAGE>

Title: Adjustable-beam permanent- magnet-focused linear beam microwave tube
Inventor: MIZUHARA YOSUKE MAXWELL
IPC: H01J23/065
Filed: 1982-09-28
Abstract: A permanent-magnet-focused linear-beam high power millimeter- wave tube is externally adjustable for optimum electron beam optics by providing an enlarged cavity within the cathode pole-piece 12 within which is housed both a confined-flow magnetically-focused electron gun 2, and a cylindrical, axially movable insert 40, 44 of magnetic material symmetrically disposed about the gun and in spaced relationship to, and adjacent, the gun insulator envelope. The insert may comprise iron, may further include a radially magnetized permanent magnet 46 and as shown in Figure 2, more than one insert of magnetic material may be concentrically employed. By axial movement of the insert within the cavity a finely controllable smooth adjustment of the beam diameter in the beam-microwave interaction region of the tube is effected over a wide range during initial operation. Substantially only the magnetic field in the vicinity of the gun is affected (Figure 3, not shown), and essentially no scalloping degradation of the beam in the interaction region is observed. <IMAGE>

Title: Aligning photomask with wafer
Inventor: KOSUGI MASAO
IPC: G03F1/00
Filed: 1982-12-15
Abstract: The line width of the alignment pattern on a mask is sufficiently narrow so that on exposure of a resist covered wafer to the mask the mask pattern is transferred to the resist but the alignment mark is not. The pattern of the mask is formed so that the line width of the alignment pattern is thin as compared with that of the actual element pattern, so that the exposure amount, in the alignment pattern portion on the resist is high due to diffraction phenomenon and thus, the alignment pattern of the mask is not transferred onto the wafer.

Title: Differential locking mechanism
Inventor: LINGARD CLIVE
IPC: F16H48/30
Filed: 1983-04-05
Abstract: One axleshaft 16 is variable in length by means of a splined coupling 29 and when in the lengthened position engages both one side gear 13 and an internally-splined locking block 18, which is between the side gears, with the splined inner end 27 of the axleshaft.
