Title: A gauging device for grinding machines
IPC: B24B41/06
Filed: 1958-12-12
Abstract: 847,344. Linear-dimension gauges. CINCINNATI MILLING MACHINE CO. Dec. 12, 1958 [Dec. 30, 1957], No. 40131/58. Class 106 (2). [Also in Groups XXIII and XXIX] A rotating workpiece 15 is supported during grinding by shoes 13, 14. The shoe 14 is pivoted and moves in accordance with the reduction in diameter of the workpiece. An arm 28 secured to the shoe 14 has an abutment surface 29 facing an orifice 30 on the end of a nozzle 31. Compressed air is supplied to the nozzle 31 through regulating valve 131 and throttle valve 133; as the workpiece is reduced in diameter, the shoe rocks clockwise and moves the abutment surface 29 closer to the orifice 30 so as to restrict the outflow of air from the orifice and thus build up back pressure to operate pressure switches 143, 144 through pneumatic relays 136, 137 provided with a source of constant reference pressure through a regulating valve 140. The grinding wheel 18 is fed into the workpiece at a coarse feed rate until the workpiece has been ground to a predetermined diameter whereupon pressure switch 143 is operated, this causing illumination of an amber signal light and reduction of the feed rate to a fine feed rate. This continues until the workpiece has been ground to the desired diameter whereupon pressure switch 144 is operated, this causing illumination of a green signal light and retraction of the grinding wheel.

Title: Improvements in or relating to Time-Division Multiplex Telecommunications Exchange Systems
IPC: H04Q11/04
Filed: 1968-08-23
Abstract: 1,192,500. Automatic exchange systems. SIEMENS A.G. 23 Aug., 1968 [24 Aug., 1967], No. 40403/68. Heading H4K. Substations such as T1 to T256 are concentrated over a two-stage cross-point network RK giving access to terminals such as AL1 to AL48 multiplexed by gates ZS on to a time division highway MS, the crosspoint network RK having a route-finding network RKS. Call originations are detected by a scanner comprised of address register AG, decoder TSD, and line circuits B1 which pass a signal to supervisory highway MY if a looped condition is encountered. The scan halts on a calling condition until a connection has been set up over RK and loop supervision is transferred to a tdm terminal circuit AS1 to AS48, changes of loop condition from that point being signalled over supervisory bus YM synchronously with highway gating as controlled by circulating store U. A number of subscriber groups may be governed by the same control circuit, an address generator GG associating each group such as TG1 with the control circuit S over gate SI1 and highway MYR and associating the corresponding route-finding network RKS over a gate SI2. A call origination halts scanner address register AG and presents the calling line address to register AR from which it is indicated, by way of decoder DB, which one of the 16, 16 x 6 first stage switches of RK serves the calling subscriber. Each first stage switch has a link to each of the 6, 16 x 8 second stage switches. A decoder BD marks one of six wires in turn indicative of a particular second stage switch. A decoder AD for each setting of decoder BD marks each of eight wires in turn corresponding to each of the eight outlets of each second stage switch. For each of the 16 outlets of decoder DB an array of six diode/relay contact cross-points connect the outlet to gates G1 to G6 if the corresponding interstage links are free. Similarly for each of the 8 outlets of decoder AD an array of six diode/relay contact cross-points connect the outlet to gates 1G to 6G if the corresponding outlet of any one of the second stage switches is free. The outputs of gates G1 to G6 and 1G to 6G are oommoned and taken as inputs to an AND gate GI. Thus for a given setting of BD indicating a particular second stage switch, if the corresponding gates Gn, nG both open, a free outlet from the second stage switch exists and a free link gives access to the switch from the first stage switch of the calling sub-station, gate GI opening to pass the identity of the accessible outlet to control S and thence to the register AR which sets up the connection across network RK. Call terminations are effected in the same fashion by supplying AR with the called sub-station identity. In searching for a free path the scanner decoder BD may cycle over all its outlets for each set of the decoder AD. The outlets of decoder AD may be employed to mark the sets of AND gates direct, in the fashion of BD as shown, while BD scans the gates over idle/busy contacts in the fashion of AD as shown.

Abstract: 1,193,215. Zearalanone; zearalanol. COMMERCIAL SOLVENTS CORP. 27 Aug., 1968 [28 Aug., 1967; 15 Aug., 1968], No. 40836/68. Heading C2C. A method of preparing zearalanone, having the formula from zearalanol, having the formula which comprises: (a) slowly reacting chromic acid or the chromate of an alkali metal with an organic solution of zearalanol; (b) diluting the solution with sufficient water to separate the zearalanone from the solution as a precipitate; and (c) separating the precipitated zearalanone from the solution. The high melting diastereoisomer of zearalanol may be produced by dissolving a mixture of the high and low melting diastereoisomers of zearalanol in warm glacial acetic acid, cooling to precipitate the low melting isomer of zearalanol, and after separating the crystals, diluting the separated solution with water to precipitate the high melting isomer of zearalanol. The low melting diastereoisomer is then oxidized to zearalanone by the above process, and then reduced to give a mixture of the high melting and low melting diastereoisomers of zearalanol. The procedure is repeated whereby the low melting diastereoisomer is recycled to extinction.
