Title: Force Balance Transducer System
IPC: G01L1/08
Filed: 1980-05-23
Abstract: A force balance transducer comprises a magnet 12 within the magnetic field of which is arranged a coil 20. The magnet and coil are relatively movable and means 22, 24 are provided for applying to the movable member (the coil as illustrated), in opposite directions, a reference force and an unknown force respectively. By applying currents to the coil to balance the applied forces and measuring the current in the presence of the reference alone and with the unknown force respectively, the magnitude of the unknown force can be calculated from the value of the reference force. The reference force may be applied by a weight 22 or a spring and the unknown force by a pressure fluid applied to a differential pressure transducer 24. <IMAGE>

Title: Rotary fluid joint with coolant ducts
IPC: B23B31/30
Filed: 1981-02-06
Abstract: Pressure medium is supplied from a stationary structural component (12) to a rotary sleeve (13) engaged therein, the components enclosing a sealing gap (14) through which pressure medium can flow away from a connection whereat a radial pressure medium inlet duct (17) connects to an annular duct (19) in the sleeve, wherein coolant ducts (31) are provided in the sleeve in the zone of the sealing gap, such ducts extending parallel to the axis of rotation. The ducts (31) can communicate with outlet channels (34) which partially evacuate during rotation to cause coolant to be sucked into the coolant ducts. The sleeve operates a machine tool workpiece chuck. <IMAGE>

Title: Improvements in artificial limbs
IPC: A61F2/50
Filed: 1981-03-03
Abstract: A method of making an artificial leg includes the step, of selecting a foot assembly from a range of foot assemblies each of a different kind but each having a like connecting member (7). In each foot assembly the connecting member has a mating surface (14) defining a receptacle (10) which engages a corresponding surface on a shin member, e.g. a shin tube, and which is in a defined position within the foot assembly so that the foot assemblies are all interchangeable. The shin member can be clamped into position in receptacle (10) by tightening a screw across a slot (13). The prosthetist is therefore able to detach one foot assembly from a patient's artificial leg and replace it with another of a different kind without altering the length of the shin member for that particular patient. <IMAGE>

Title: Testing plastics coatings on optical fibres
Inventor: BARKER MICHAEL RICHARD
IPC: G01N3/00
Filed: 1981-08-06
Abstract: The state of cure and/or adhesion of a plastics coating on an elongate member, such as an optical fibre, is determined by measuring the load (peel load) on the fibre (28), by means of a load cell (12) mounted on a cross member (10) driven by an electric motor (1), whilst holding (at 14) the fibre in a tensioned monofilament loop (30 - Figure 3). The loop serves to fracture the coating at a particular peel load (A - Figure 5) which is indicative of the state of cure. After such fracturing, and whilst the load continues to be increased, the monofilament loop peels the coating back, the extent of peel back being indicative of the coating adhesion. <IMAGE>
