Title: Improvements in machines for dressing external cylindrical surfaces
IPC: B24B5/04
Filed: 1938-03-25
Abstract: 510,627. Grinding. BURGESS, A. F. (Barnes Drill Co.). March 25, 1938, No. 9180. [Class 60] A machine for dressing external cylindrical surfaces has an elongated horizontal bed on which is mounted a fixture carrying a cylindrical abrasive tool concentrically of a workpiece rotatably supported on a carriage which is reciprocated by power-actuated means controlled to limit the stroke to substantially the length of the work-piece. The tool 25, Fig. 2, comprises a number of abrasive blocks surrounding the work-piece and radially adjustable by known means. The carriage is reciprocated by a cable 40 passing round a drum 35 rotated by a fluid-pressure motor supplied by an electrically driven pump. Adjustable limit switches 91, 92, operated by a dog 94 on the carriage, reverse the fluid-pressure motor at each end of the stroke by means of solenoids operating a pilot valve which controls a fluidactuated reversing valve. A manual control 110 is also fitted. A delay valve may be included in the fluid system to effect a dwell at one or each end of the stroke. Buffers 48 are provided on the carriage to contact an adjustable stop 46a and arrest the carriage positively at the end of the stroke when dealing with shouldered work. The work-piece may be rotated continuously by an electric motor for honing or indexed by fluid-operated ratchet mechanism for lapping, the selected drive being clutched to a splined shaft 50, Fig. 6. The shaft 50 is mounted at one end in a bearing fixed to the bed whilst the other end telescopes into a sleeve on the carriage. The carriage is fabricated from sheet material welded together to form a box-like frame with stiffening divisions and gusset plates and a central trough 79 into which coolant supplied to the tool drains. Rollers 19, mounted on antifriction bearings and running on guides 17 on the bed, are disposed at intervals along the sides of the carriage. The machine may be stopped automatically by a timing or stroke counting mechanism.

Abstract: 831,373. Railway track circuits. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. STIN. March 25, 1958 [April 2, 1957], No. 9492/58. Class 105. In a railway track circuit in which a track relay is connected to an insulated rail section in circuit with a source of current so that on the passage of a train over the section the insulated rail is connected to earth over the other rail and the energizing circuit for the relay completed, the source of current is continuously connected alternately through the contacts 01, 02 of a change-over switch 24, e.g. of the thermally operating mercury type, to two track relays 21, 22, connected to respective insulated rail sections 11, 12 and the two leads 31, 32 from the switch to the relays 21, 22 are connected through a checking relay 23 arranged to be held operated during normal operation of the change-over switch 24 and on a continuous de-energization to return to its unoperated condition to indicate a fault in the track circuit. The checking relay 23 is thus connected alternately in series with one track relay and then the other in a circuit through the track impedance represented by elements 41, 42, to earth. An additional resistor 51 or 52 may be provided in parallel with the track impedance to ensure a current path under abnormal atmospheric conditions and the characteristics of the track relays and the checking relay are so chosen that in the absence of a train axle a current flowing through a track relay and checking relay in series operates the checking relay but not the track relay. The checking relay has a falling-off delay period greater than the changeover period of the switch to maintain it continuously operated by the intermittent energization through the switch.

Abstract: 643,815. Locking rods. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G., and LLOYD, J: April 7, 1948, No. 9703. [Class 80(iii)] [Also in Group XXIX] An arrangment for locking a rod in a push-pull connection until lost-motion has been taken up and, on return movement, for bringing the rod back to its initial position before the lost motion is again effective, comprises a tube 26 pivoted at 31 to a plate 29 itself pivoted on a fixed pin 30, and an actuating rod 25 slidable in the tube 26 and having a pair of pins 27 working in slots 28 in the tube and engaging surfaces 33 of the plate 29. The rod to be actuated is fixed to the right-hand end of the tube 26. The arrangement is such that the pins 27 prevent angular movement of the plate 29 about the pivot 31, and therefore prevent axial displacement of the tube 26, until the lost motion provided by the pins and slots 27, 28 has been taken up, when one of the pins will have moved beyond one of the surfaces 33 to permit movement of the plate 29. On return movement. the plate 29 must come back to its initial position before the lost-motion is again available. The device is described as employed in a fluid-pressure servomotor system (see Group XXIX).

Filed: 1929-03-26
Abstract: 326,672. Siemens Bros. & Co., Ltd., and Peters, C. L. March 26, 1929. Automatic exchange systems.-In a system in which two automatic sub-exchanges are reached from a manual board over an omnibus junction, the dialled impulses from the manual board are transmitted to the exchange required only, but the junction is marked busy at both exchanges. When a call is made from one of the subexchanges to the manual board the junction is at once marked busy at the other exchange. Arrangements for an automatic "ring-off" are provided where the manual board equipment is of the magneto type. Call from main to sub-exchange. The line relay L is connected to the a wire at one of the subexchanges and to the b wire at the other (shown in Figs. 2 and 3). To originate a call the operator plugs into the jack JJ operating relay J which connects earth to both a and b wires energizing the relays L at both exchanges. Relay V operates. followed by DA, DB and CO, which last relay disconnects the line relay LA and marks the junction busy in the banks of the call finder CF. The operator now plugs the dialling plug DP into the jack JA or JB corresponding to the exchange required and dials a digit which may have any value, as it has only a preparatory effect. Relay L in the exchange required responds and on the first de-energization of L, E operates and locks up, releasing CO, and when the train finishes, DA and DB release, and LA operates, marking the junction in the banks of CF and completing a circuit through PG to start CF hunting, CO operating when the junction is reached. Dial tone is returned to the operator who dials the number required, the digits being repeated at l3 to the automatic switches. When the called subscriber answers, earth over d1 operates JS, which allows S to pull up. The junction is marked busy in, the banks of the connector switch CS at the other exchange by the break in the circuit cl, c2 at v2. When the called subscriber clears, JS releases, and Z operates, breaking the circuit S and starting at z4 the ringing generator which gives a " ring-off " signal to line over RO. Aftera slow-release pause S falls back and Z releases. When the plug is removed from JJ relays V and L at both exchanges release, and at the called exchange E falls back, releasing the equipment. Call from sub to main exchange. The connector switch CS hunts for a free junction on which F and CO operate in series. Relay Z operates connecting ringing over RG to operate the calling indicator CD at the manual board. Earth is connected to the a (or b) wire to operate the line relay L at the other sub-exchange to mark the junction as busy. When the operator plugs in, TR pulls up, locking over its winding (II), releasing Z and operating E which connects up the speaking leads. Relay Z releasing enables L to pull up to energize V, followed by S. When the conversation is finished F releases, operating Z, which rings off the connection, and the switches release as before. Calls between the two exchanges pass via the manual board.

Abstract: 419,198. Fire, police, and like alarm systems. GILL, H. A., 51, Chancery Lane, London.-(Elektrozeit Akt.-Ges.; 136, Mainzerlandstrasse, Frankfort-on-Main, Ger. many.) March 28, 1934, No. 9726. [Class 40 (i).] In a system in which signals are transmitted by battery reversal, a different signal is given if a fault occurs in the line. Under normal conditions relays Da and Db are energized and hold their contacts open as shown. To make an alarm call the handle C is pulled down, reversing the current flow over the parallel-connected conductors a, b and cutting out resistances W1 and W2. Relay P responds and A energizes to connect up an alarm not shown. Should a fault occur in the line wires, either relay Da or Db or both relays will fall away closing a circuit for hot-wire relay Hi. After an interval Hi closes its contact so that relay X pulls up and locks independently of Hi, energizing relay B which connects up a fault alarm. The indicator SZ, in series with relay X, indicates when the trouble has been cleared. The resistances Wl and W2 protect the battery O from being damaged if either of the lines a, b becomes earthed.

Abstract: 592,797. Type printing telegraphy; valve circuits ; thermionic distributers. NATIONAL CASH REGISTER CO. May 19, 1944, No. 9748. Convention date, Feb. 25, 1943. [Classes 40 (iii) and 40 (v)] In a telegraph system in which bursts of signals representing symbols are set from an electronic impulse generator at the sender to a receiver over a single channel, each burst comprising a number of substantially identical signals according to the symbol to be transmitted, a number of groups of electronic. devices are provided at the receiver, means being provided at the receiver which operates during the intervals between the bursts to route each to a different group, each group being controlled by the number of signals in the group to set up a direct representation of the associated symbol. The system described is similar to that described in Specification 592,796 bursts of impulses being transmitted with spaces between successive bursts and at the receiving end control impulses are generated during the spaces, to route the bursts to the correct bank of counting tubes. Fig. 1 shows a bank of gasfilled tubes which fire in succession after the tube connected to the depressed key has been fired by an impulse from a " start " tube, Fig. 6 (not shown). Condenser 163 delays the potential rise of the grid of the " shift " tube due to tube (0) firing thus delaying the firing of the '' shift " tube so that a space is provided between one burst of impulses and the next. The negative impulses are transmitted to terminal 335 on the control impulse generating means, Fig. 7, at the receiver. Tubes 340, 341 are connected as a trigger pair, tube 340 being normally conducting, as are tubes 337 and 343, while tube 342 is cut off. Negative impulses applied to the grid of tube 337 render it non- conducting so that its anode potential rises and positive impulses are applied through condenser 396 to the grid of tube 341 causing it to conduct, thus cutting off tube 340. The positive impulses from tube 337 applied through condenser 439 reduce the bias on the grid of tube 342 causing it to conduct. The drop in anode potential is applied to the grid of tube 340 to prevent it conducting. The values of condenser 425 and 'resistor 426 in the anode circuit are such that, when valve 342 becomes non-conducting after each impulse, its anode potential only rises slowly so that the next impulse arrives before the bias on tube 340 has been reduced sufficiently to cause it to conduct. Tube 340 thus remains non-conducting during the bursts of impulses but conducts again during the intervals between bursts. When tube 340 conducts a negative impulse is applied to the grid of pulse sharpening tube 343, cutting it off and producing a positive control impulse at terminal 462, which is applied to the routing means as in Specification 592,796. Positive impulses from the anode of valve 337 are fed selectively to the corresponding banks of counting tubes, selected by the routing means.
