Title: Universal roll stand
IPC: B21B13/10
Filed: 1972-09-04
Abstract: 1358646 Rolling mills SCHLOEMANN AG 4 Sept 1972 [6 Sept 1971] 40889/72 Heading B3M A universal rolling stand includes a main frame 1, which supports a pair of vertical rolls 10, 11 and provides guide surfaces for the chocks 7a, 8a of a pair of horizontal rolls 7, 8, and two frame caps 3 and 4 which are secured by adjustable (but not prestressed) tie rods 5 to the main frame. The tie rods are each oppositely threaded at 18a and 19a so that rotation of the rods cause the caps 3 and 4 to move towards or away from each other, thereby adjusting the gap between the horizontal rolls. The rods are carried in the main frame by bearings 32 and 33, and are rotated in unison by motor driven worm gear units 25. The upper end of each rod has a threaded sleeve 27 on which a nut 30 is carried. Springs 31 act on each nut to urge the housing cap 3 upwardly in order to take up backlash between the threaded portion 18a of the rod and a surrounding adjusting nut 18. To remove the rolls from the stand, the nuts 18 are rotated upwardly on the the tie rods until they move on to the sleeves 27. The cap 3 can then be raised by a crane, and the rolls lifted successively from the main frame. The chocks 8a of the lower roll 8 are made narrower than those of the upper roll to facilitate their removal. The vertical rolls are adjusted by rotating threaded spindles 17 by motors 16 (one for each roll). A vernier scale 22 (Fig. 2) is associated with one of the tie rods to give an indication of the screwdown position of the horizontal rolls.

Abstract: 1409150 Artificial knee joints SULZER BROS LTD 31 Aug 1973 [1 Sept 1972] 41044/ 73 Heading A5R A prosthetic implant for a knee joint comprises tibial and femoral components with elongate anchorage portions 10, 1, one component having bearing surfaces 9 and a web 14 projecting between them arid the other component having bearing surfaces 6, for cooperation with the surfaces 9, extending from the arms 5 of a fork which embrases the web when the joint is assembed, the web being provided with a sot 15 which has a part extending obliquely to the axis of the corresponding anchorage portion and which receives a pin 8 which is attached to the other component. The slot may have a portion near the bearing surfaces which extends substantially parallel to the axis of the anchorage portion and the parts may be shaped so as to relieve the pin of bearing loads. Plastics materials may be used for spacers 18 between the web and fork arms and for bearing surfaces inserts 19. The anchorage portions taper in cruciform cross section and a triangular web 12 at the top of the lower shank prevents rotation of the joint relative to the bone. The surfaces 6 are cylindrical whilst the profile of the surfaces 9 is formed by circular arcs. An opening in the web allows the pin to be engaged in the slot during joint assembly, a closing piece 16 being subsequently fitted. Metal parts of the joint may be in alloys of cobalt, chromium, nickel and molybdenum. The plastics materials may be polyester.

[Also in Division F4] In a power plant steam or other vapour from a boiler 1 passes through a pipe 11 and is mixed in an injector 7 with water or other liquid passed from the boiler through pipe 12, the mixture driving a motor 3 such as a turbine, gear, or Roots blower type motor. Water collecting in a sump 5 on the outlet side of the motor 3 passes through pipe 6 to an injector 7a and is forced back to the boiler 1 through pipe 9 by steam feed to the injector 7a through pipe 14 from the casing of motor 3. Alternatively the injector 7a may be powered by steam taken directly from the boiler 1. In a modification, Fig. 1 (not shown), an injector is not provided on the input side of the motor 3 and the latter is driven by water forced from boiler 1 under boiler steam pressure. Flow control valves are provided in the appropriate pipes. Auxiliary steam turbines or heat exchangers may be provided in the steam pipes leading to the injectors. The steam passing through the pipes may be super-heated. When the motor 3 is a turbine it may be of Pelton wheel type. Instead of water, boiler 1 may contain a liquified gas e.g. air, or a gas such as air in a solvent liquid such as water.

Abstract: 1,119,856. Controlling pressures in reaction vessels. GENERAL ELECTRIC CO. 7 Oct., 1965 [12 Nov., 1964], No. 42589/65. Heading B1X. [Also in Divisions G1 and H5] A device for detecting and compensating for pressure decay in a reaction vessel comprises a pressure monitoring unit 33 disposed in the wall of the vessel and a pressure compensating unit consisting ofa body of material 47, e.g. silicon or germanium. located at a position in the vessel where the temperature is near the melting point of the material such that a volume change of at least 5% of the material can be effected by a change in state to compensate for pressure decay detected by the monitoring unit. The monitoring unit comprises a piece of germanium 36 contained in a graphite enclosure 34 (Fig. 4) and a temperature sensing device 32 in contact with the graphite. Germanium is chosen due to the linear nature of its fusion curve (see Fig. 5 not shown). The reaction vessel 14 which is preferably of sodium chloride is received in the volume 17 defined by punches 12 and 13 and belt 11 of a high pressure apparatus 10, gaskets 20-22 completing the assembly. A second temperature sensing device 31 is located centrally of the vessel adjacent the sample 46, e.g. comprising a diamond seed, graphite and a catalyst. A first circuit comprising in part a heating tube 44 heats the vessel and sample to the required high tem-  perature, and a secondary heating circuit controls the phase transformation of the silicon body 47. The pressure calibration for one particular vessel are obtained (see Fig. 8 not shown) and during conduct of the high pressure process, since the temperature recording for a given melting of the germanium body 36 has a corresponding pressure value on the graph of Figure 5, the variation in the pressure in the vessel is determined and can be compensated for.

Abstract: 1450172 Remote meter reading system; electronic counters WESTINGHOUSE ELECTRIC CORP 13 Sept 1973 [22 Sept 1972] 42989/73 Headings G4A and G4D In a metering circuit for a remote meter reading system in which the circuit counts meter pulses before transmitting them to a central location, the circuit comprises a binary counter with non-volatile memory for storing the reading during power failure, an encoder having inputs for the counter outputs, sampling inputs and an output, and a readout control circuit responsive to a start signal to generate a serial binary data word from the encoder and the circuit is formed as a modular integrated circuit of the metal nitride-oxide semiconductor (MNOS) type. The system is designed to read a plurality of meters 15-15N in series using circuits (modules) 14-14N with memories 35-35N. Pulses representing (say) 10 Kw.hr. from meter 15 are fed to module 14 where they are shaped by input circuit 45 and increment binary counter 46. Each pulse also passes via delay 57 and pulse generator 58 to transfer the meter reading to the memory which comprises FETs with an insulating layer and a controlled thickness layer of silicon nitride so that it stores charge carriers. The counter is reset externally or at the count of 1000 10  by circuit 47. To read out, a start command is received by data set 20. This activates circuit 50, to which clock pulses (mains frequency) are also supplied and passes the clock pulses to readout control counter 52. An inhibit pulse is also supplied to input circuit 45 to prevent change of counter reading. The first 16 pulses to counter 16 define a delay period. The next pulse is sent as a start signal to the next module 14A and serially passes out the data from the first stage of parallel to serial converter 48. The contents of the other 15 stages follow, the order being 1 sync.; 2-11 reading; 12-14 identification; 15 parity (generated by calculator 53 from reading output) and an end pulse 16. The data pulses pass via output buffer 54 on to the output line 22 for transmission, e.g. by telephone cable to a central station. The 16 clock pulse transmission period of the module 14 is the delay period of module 14A which then activates 14B and transmits its data via its own output of a buffer 54 of module 14. Each module transmits in turn the outputs appearing serially. The start command signal then ceases and data set 20 disconnects the system from line 19.
