Title: Apparatus for Controlling the Movement of Structural Shapes or Beams through a Punching Machine.
IPC: B21D28/26
Filed: 1916-09-02
Abstract: 109,988. Marks, E. C. R., (Steel Utilities Incorporated). Sept. 2, 1016. Punching.-Apparatus for controlling the relative movements of structural shapes or beams and mechanism for punching the same comprises rolls 1 driven by a motor 9 for conveying the work x past the punching mechanism 10, a stop 15 on a rack-bar 16 engaged by a pinion 18 on a shaft 19, and a number of members 40, 65, 69, 74 adapted to be moved by a travelling member 26 on the shaft 19 and controlled bv settable distance-devices such as keys 45, 68, 71, 76, whereby the stop 15 is advanced a distance determined by the setting of the keys. The shaft 19 rotates in a casing 23 provided with an interior thread 24 engaged by a thread 27 on the member 26, which is mounted on a squared portion of the shaft. A sleeve 28 on the member 26 has a stop-piece 29 and forms a bearing for a cylinder 30 provided with a threaded sleeve 31 passing through a nut 33. The nut 33 has an arm 34 projecting through a slot in the casing 23 and connected to a slidable plate 40 supporting a plate 44, in which are mounted keys 45 corresponding to a distance de. nomination. The keys are vertically reciprocable in the plates 44, 48, and 40 and, when set, engage slots in a slidable plate 65, the length of the slots being proportional to the distance value of the keys set. The set key is locked by a spring plate 48, which engages the upper surface of a coned shoulder 47 on the key stem, and is released when another key, in being set, deflects the plate 48 against its spring. Other sets of keys 68, 71, 76, denoting different distance denominations, are similarly mounted in slidable plates 65, 69, 74, and, when set, engage slots in plates below those in which they are mounted, the last plates 78 engaged by the keys 76 being fixed. Fractions of the lowest unit of distance are denoted by keys 99 reciprocably mounted in plates 91, 100, and a plate 90 fixed to the nut 33. The keys, when set, engage slots 101 - - 104 in the cylinder proportional in length to the values of the keys. When the members 26, 30, 33 have moved along the shaft 19 a distance corresponding to the value of the set keys 45, 68, &c., the plates 40, 65, &c., and nut 33 stop, and for the movement of the member 26 overcomes a spring 107 and brings crown teeth 106 on the member 26 into mesh with teeth 105 on the cylinder 30. The cylinder is thereby rotated until the set key 99 reaches the end of the slot 101, &c., and the cylinder advances relatively to the nut 33. The plates 40, 65, &c., are drawn together by a spring-pressed rod 109. When the punching is completed, the controlling apparatus may be restored to starting position by a motor 120. The starting and stopping of the motors 9, 120 and the setting of the keys may be controlled by a distance-record device such as a perforated strip, as described in Specification 12139/15.

Title: Improvements relating to fluid-cooled brakes
IPC: F16D65/12
Filed: 1948-05-07
Abstract: 653,565. Brake cooling systems. DUNLOP RUBBER CO., Ltd.,' and PENDLEBURY, J. A. May 7, 1948, No. 12561. [Class 103 (i)] A brake friction member is cooled by liquid sucked into the interior of said member by means of an injector device located thereir and actuated by vapour generated frorr the liquid by the heat produced in braking. In Fig. 5, the invention is shown applied to an aircraft wheel assembly having a fixed axle 27, rotating wheel hub 23 and friction pads 35, 36 moved axially by a conventional fluid pressure actuator 38 into engagement with the rotatable brake member 1, 2. The brake member is made in two halves 1 and 2, with a series of interleaving fins 3 and 6 which together provide a system of sinuous passages within the member. Spaced at equal intervals around the brake member and located between the two halves 1 and 2 are three radially extending injector assemblies, as shown in Fig. 3. Each injector assembly comprises a jet 8, converging nozzle 11, diverging nozzle and ball valve 13, 14, 15 and vapour outlet passage 17a. Spaced between the injector assemblies are exhaust assemblies 20, Fig. 4, comprising inlet ports 21, radially extending tubes 19 and relief valves 22 set to open at approximately 75 lbs. per square inch. Cooling of the brake takes place as follows. When braking is about to take place, a valve is operated to allow cooling liquid to flow through passages 33b, 33a, into the annular chamber 33 around the internal diameter of the brake member. When the brake is applied the heat generated vaporizes a quantity of liquid that has been left in the brake member from a previous application. This vapour begins to eject from the nozzle 8 and in so doing sucks up liquid from chamber 33 and forces it from the convergent nozzle 11 into the divergent nozzle 13 and past the ball-valve 14, 15 to circulate around the passages within the brake member until this liquid is itself vaporized. Excess vapour escapes by the passage 17a and outlet 18, the pressure within the brake being limited by the relief valve 22. A system is thus provided in which the circulation of cooling liquid is automatically varied in proportion to the heat generated in braking. Cooling fluids that may be used are water, alcohol, ethylene glycol or a mixture thereof.

Title: Method and device for the automatic measurement of the length of yarn consumed in knitting machines
IPC: D04B35/10
Filed: 1970-03-16
Abstract: 1,254,516. Measuring length of yarn. INSTITUT TEXTILE DE FRANCE. 16 March, 1970 [17 March, 1969], No. 12631/70. Heading G4H. [Also in Division D1] In a device for measuring the length of yarn used per stitch in a knitting machine, the yarn rotates a positive feed wheel 1. The wheel carries a disc 2 having alternate reflecting and non-reflecting segments, which are scanned by a lamp and photo-detector 3 to produce a train of equi-weighted pulses. These pulses pass via an amplifier and shaping unit 4 and a gate 5 to a counter 6. A dog (8) Fig. 2a (not shown) rotates with wheel 1 and actuates microswitches 7 and 16 in turn. A pulse produced by 7 passes through shaper 9 to a preselection counter 10 and the switch 12. Initially switch 12 has the position shown and the pulse from 7 opens gate 5. In this way, the number of counts per revolution of the wheel is detected. This enables the number of stitches produced in a number of revolutions to be determined, so that by setting the value of the preselection counter and adjusting the positions of the microswitches 7 and 16 a given number of stitches are produced between opening and closing of gate 5. When microswitch 16 is actuated a signal is produced which closes gate 5 and so stops the count. The control unit 21 controls the detailed action of the gate depending on the type of knitting machine employed. By adjusting the number of stitches for which the count is recorded, the display on the counter can be made to indicate the total length of yarn per 100 stitches say.

April 30, 1930, No. 12894/31. Divided on 356,102. [Class 118 (ii).] A vehicle-actuated switch for a road traffic control system comprises spaced resilient conductor sheets enclosed in a flexible casing, fitted into a rigid open-topped rectangular casing adapted to be sunk in a roadway with its upper edges substantially level with the road surface, the top of the rigid casing being closed by a flexible pad which also has its upper surface substantially level with the upper edges of the rigid casing and with the road surface. Thin resilient conductor sheets 312, 313, Fig. 2, spaced at their ends by resilient insulators 316 are enclosed by a heavy fabric covering 317, then by a waterproof rubber casing 318 and by another fabric covering 319, as insulating tape, the whole being then cemented into a rigid open-topped box 311, preferably of cast steel. A tread member 320 such as heavy tread rubber, may be cemented or vulcanized to the flexible casing 319 and is fixed on a ledge 329 of the box 311 by bolts 322 and wedge members 323, 324 which serve to regulate the tension in the tread member 320 to maintain the latter substantially level with the road surface. Alternatively, when traffic in one direction only is to actuate the signals, the upper contact strip 312, Fig. 2, is replaced by two strips 402, 403, which successively contact with the strip 404, Figs. 5 and 6. Control circuits. A vehicle passing in the direction of the arrow, Fig. 5, contacts firstly the plate 402 and then the plate 403 with the plate 401. Relay 410 is energized to bring armature 412 to contact 415 after which the circuit of the signalling or other control means S may be closed at contacts 401, 403 and 415, 412. A vehicle passing in the opposite direction would actuate the relay 411 to open the circuit of relay 410 at contacts 413, 416 so that when the vehicle depressed contact 402 the signalling means S would not operate. In a modification, Fig. 6, a vehicle passing in the direction of the arrow operates the relay 411 at both contacts 402, 403 to close the contact 422 in the circuit S. An opposing vehicle would close contacts 403, 402 successively to energize the relay 410 which at armature 412 opens the circuit to relay 411 so that contact 422 cannot be operated. The road switch may be adapted to actuate a traffic counting mechanism.

Title: Improvements relating to the production of malleable iron
IPC: C21D5/10
Filed: 1945-05-24
Abstract: Malleable iron is produced by heating white cast iron at a temperature of above 850 DEG C. and below the melting point of the iron in a substantially gas-tight furnace in a gaseous medium capable of decarbonizing but not of oxidizing the iron, the gaseous medium being produced at least initially by passing air and/or steam over carbon, e.g. charcoal or coke, maintained at 750 DEG -1100 DEG  C. by a separate source of heat, the temperature being controlled within those limits so that the proportions of carbon monoxide and dioxide and, if steam is used, of hydrogen and water vapour are such that at the temperature of the cast iron decarburization, without oxidation, of the latter is effected. The gas is caused to circulate between the furnace and the carbon container and air and/or steam is added at a controlled rate, continuously or intermittently to the circulating medium a corresponding quantity of used medium being simultaneously withdrawn from circulation.  At least part of the gas issuing from the charcoal furnace may be recirculated through the latter without passing again over the coke or its decarburizing power being maintained by the addition of controlled amounts of water vapour and/or air and/or carbon dioxide before or as the gas re-enters the furnace.
