Abstract: 931,836. Universal joints. G. S. McLAY. Sept. 28, 1961 [Nov. 15, 1960; Feb. 22, 1961; April 5, 1961], Nos. 39221/60, 6511/61 and 12207/61. Class 80 (2). To obtain more even loading of rubber &c. pads 42 in a universal joint of the type comprising interdigitating axial fins 34, 36 on hubs fast with driving and driven shafts, the pads are formed with opposite smooth faces lying in planes which intersect in lines 44, 45 parallel to but beyond the axis 43 of the joint. In the form shown, two pads 42 and a solid wedge 41 between each pair of fins 34, 36 form a resilient element 37, outwards movement of the rubber pads being prevented by a cap plate 39 bolted in position. A tie-rod 38 connects the resilient element 37 to a similar diametrically opposite element (not shown). The fins 34, 36 are so spaced that the hubs can easily be separated by relative radial movement. The pads 42 may be bonded &c. to the wedge 41. In one modification, Fig. 4 (the second Provisional Specification) (not shown), the pads are bonded to the solid wedge and are formed with inner projections abutting plates bolted to the driving and driven fins. In another modification, Figs. 5, 6 (the third Provisional Specification) (not shown), two pads are bonded to opposite sides of a parallel-sided plate to make each resilient element, and a cylindrical shroud bolted to one of the hubs surrounds the joint to prevent the elements flying radially outwards. The plates may alternatively be wedge-shaped, the greatest thickness of these wedges lying towards the joint axis. Figs. 1, 2 (the first Provisional Specification) (also not shown) illustrate a known similar universal joint having the planes containing the smooth side faces of the resilient pads intersecting in a line coincident with the axis of the joint.

Abstract: 1482001 Controlling light F HOFFMANNLA ROCHE & CO AG 13 Sept 1974 [13 Sept 1973] 40098/74 Heading G2K The transparent plates of an optical liquid crystal cell are bonded and spaced by a gasket formed of thermoplastic material including a thermoplastic resin which is neither soluble in nor reactive with the crystal material. In particular the resin may be a phenoxy polymer made by reacting bisphenol A and epichlorohydrin, with a molecular weight of 6,000 to 30,000 and preferably above 20,000. A modifier such as an uncured solid epoxy or other low molecular weight resin e.g. coumarene-indone or phenoxy resins, small amounts of an organosilicon compound and fused silica, and solvent may be added to the resin to give a material suitable for forming the gasket by silk screening. If the modifier reacts with the liquid crystal material an inert material such as a silicone resin is disposed between the gasket and liquid crystal material. Alternatively the resin can be a high molecular weight solid epoxy with widely separated epoxy rings reacted to give it some thermoset while retaining its essential thermoplastic character, or a phenoxy resin can be used as a plasticizer or modifier in another compatible resin. Some of the hydroxy groups in the phenoxy resin can be cross-linked e.g. with melamine or phenol formaldehyde. The cell may exhibit dynamic scattering or voltage controlled optical activity twisted nematic cell.

Abstract: 1492626 Selective signalling WALT DISNEY PRODUCTIONS 3 Oct 1975 40599/75 Heading G4H  In a monitoring system for a large number of devices each of which can assume a normal state and an off-normal state, a central scanner 947 addresses groups of 256 devices in turn, each group when addressed responding with a first word indicating whether all the devices in the group are in their normal states or whether any is in its off-normal state, and only if any device in the group is in its off-normal state, the devices of that group are scanned by a local scanner 965, 16 at a time, to derive 16 words each including 16 data bits, each data bit indicating the state of a respective device. In Fig. 1, the computer 946 normally plays no part in the proceedings, but if the first word from an addressed group indicates a device in an off-normal condition, all 17 words from that group are sent to the computer which, by reference to a stored table, decides what corrective action is needed and transmits addressed control signals to appropriate control devices 966. The central scanner 947 includes an address counter (992). An interrogation signal comprises 18 bits, bits 1-8 are all 1's and define the signal as an interrogation signal, bits 10-17 are the address of the interrogated group, bits 9 and 18 are parity bits. Each interrogation signal is sent twice and a remote terminal unit 960 performs parity and sync checks on the signals. If more than a given number of errors occurs, unit 960 selects the second occurrence of the interrogation signal and informs the computer. All interrogation signals go to all the local scanners 965 but only that one with the correct address responds, by transmitting a first 18-bit word including 8 address bits (which are compared in scanner 947 as a check), 2 parity bits and bits denoting whether all the devices are in their normal states and whether a piggy-back group exists for that address. If all devices are normal and no piggy-back group is present, the central scanner address counter is incremented by 1 to address the next group, If a piggy back exists, it is interrogated next by changing the most significant bit of the address. If an offnormal device is signalled, the local scanning is carried out, 16 18-bit resulting each including 2 parity bits, all 17 words from the group being routed to the computer. Details of the central and local scanners are given.

As described the drill includes a bit 2 having an invil 5, the bit 2 being retained in place by split ring 3. Compressed air is supplied from connector 10 via check valve 11 to valve 20, e.g. a clapper valve, which directs the air alternately to ports 15, 16. When in the position shown in Fig. 1 air is supplied to port 15 and passes via port 19, tube 17 and ducts 22, 27 in the piston 8 to the lower chamber 30 to raise the piston 8, air from above the piston 8 being exhausted from the upper chamber 31 via a passage between the casing wall and reduced portion 28 of piston 8 and ducts 26, 23 (see also Fig. 2) in the piston and then through passages 33 past the bit assembly. When the lower portion 29 of piston 8 rises above liner 6, air in chamber 30 escapes to exhaust causing a sudden pressure drop at port 15 thereby reversing valve 20 so that air is supplied to the upper chamber 31. The piston 8 then moves downwardly to strike the anvil 5. During this downward movement, when upper section 28 of piston 8 passes shoulder 32 air is exhausted from chamber 31 causing valve 20 to reverse again, thus repeating the cycle. When the drill is lifted off the bottom of the hole, both bit 2 and piston 8 drop so that tube 17 leaves passage 22, air then being passed to exhaust for either condition of valve 20, thus preventing further reciprocation of the piston.
