Patent GB-2292462-A (GB)
Title: Transducer
Inventor: FAWCETT JOHN NEVILLE
IPC: G01P15/18
Filed: 1995-08-18
Abstract: A force transducer, e.g. an accelerometer, has a deflectable seismic mass 10 supported in a frame 11 by beams 12 which are stiff in the undesired directions of motion x, y and flexible in the desired direction z so that the mass 10 remains parallel to its rest plane when deflected. Deflection of the seismic mass is a purely translational movement with no rotational movement allowed. As shown the beams 12 are at an angle  alpha  to the frame and mass and are formed by etching using a mask, but a number of embodiments are described. The invention allows three identical structures to be etched into a flat semiconductor wafer and used to determine accelerations in three perpendicular directions (Fig. 12). Since the surfaces of the or each seismic mass always remain parallel to the wafer surface, measurement of the deflection can be made easily, for example by depositing electrodes on the surfaces of the mass and adjacent fixed surfaces (e.g. of deflection stops) and measuring the change in capacitance between the electrodes. Cross coupling effects will be negligible since each transducer is stiff in all directions except the sensitive direction. <IMAGE>

Abstract: Drinks dispensing apparatus comprises a dispensing head (4) from which beer or other liquid stored in a cask (3) is dispensed. A gas driven displacement pump (5) is used to draw liquid from the cask and deliver it to the dispensing head. Air for driving the pump (5) is provided by a "hand-pull" piston and cylinder assembly (2a,2b), the piston (2b) compressing air in the cylinder on one side of the piston during the upstroke and supplying it to an inlet (6). Exhaust air from the pump is returned, via an outlet (7) to the other side of the piston for passage through a one-way valve in the piston during the downstroke. The pump may comprise a pair of diaphragms connected by a shaft. The apparatus maintains the aesthetic appeal of traditional hand-pull dispensers but does not suffer from several disadvantages inherent in such equipment.
Patent GB-2304792-A (GB)
Title: Snap connection system
Inventor: BAYNES IAN DAVID
IPC: F16B7/04
Filed: 1995-09-08
Abstract: In a snap connection system in which a shaft 16 is inserted into a tube 10 to a predetermined position, whereat co-operating surfaces on tube and shaft engage as in a laterally acting wedge, two axially spaced spring loaded balls 12 on one side of the tube urge the shaft into wedging engagement with the tube when in position. During insertion, a further spring loaded ball 13 on the opposite side of the tube adjacent the wedge apex urges the shaft out of wedging engagement with the tube. A detent 17 in shaft 16 accommodates the further ball 13 at the predetermined position, locating the shaft axially and permitting wedging. The balls are biassed by a spring sleeve 11, and a tang 14 thereof locates the sleeve on the tube. The tang may extend to the tube interior to coact with a detent in the shaft so that unclipping is necessary for disassembly. Alternatively, a spring loaded pin extending through sleeve and tube wall may accomplish the same end.

Patent GB-2298247-A (GB)
Title: Bellows cam plate pump
Inventor: INOUKUCHI IWANE
IPC: F04B1/14
Filed: 1996-02-02
Abstract: The pump 4 comprises a pressurizing chamber 29 formed by a bellows 26 which elongates and contracts along a center axis parallel to the input shaft 16 of the pump. A cam plate 36 rotates together with the input shaft 16 and compresses the bellows 26 via a piston 33 which is guided along the center axis. Rotational torque is blocked from acting on the bellows 26 via the piston 33. Thus the bellows 26 is not subjected to a bending load or twisting load. As shown the torque is blocked by the provision of an auxiliary plate 39 restrained from rotating and supported on the cam plate 36 by bearing balls 38. Alternatively torque blocking is achieved by reducing the frictional contact between an end plate 27 of the bellows and the piston 33. To reduce the frictional contact the bellows end plate 27 is given a spherical surface or a small central projection.
