Filed: 1967-06-19
Abstract: 1,149,659. Lock actuators. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. 23 May, 1968 [19 June, 1967], No. 28228/67. Heading F2E. A lock actuator, i.e. a fluid-pressure actuator having locking means rendered inoperative by the application of a second fluid pressure has means for shortening the brake-operating- member from its normal length for emergency release of the brakes, e.g. if the lock pressure fails. In one arrangement, Fig. 1, the push-rod 4 connected to the fluid pressure actuator 2 has a castellated head 10 normally held by a torsion/compression spring to engage projecting castellations 11 on the brake-operating-member, as shown, but when turned by a tommy-bar in hole 19 the castellations mesh thereby shortening the effective length. In an alternative arrangement, Fig. 2 (not shown), the push-rod and actuating- member slide in a tubular sleeve and are held apart by a cam which when rotated shortens the effective length.

Title: Door operation and control
IPC: E05F15/12
Filed: 1949-11-04
Abstract: 682,518. Control of motors. NATIONAL PNEUMATIC CO. Nov. 4,1949 [Nov. 4,1948], 28340/49. Class 38 (iii) [Also in Groups XXV and XXXV] The doors of a motor vehicle are operated by a series-wound electric motor controlled by a circuit comprising a magnetic relay adapted to reverse the direction of current flow through the armature winding, and switches 60, 62, 64 actuated by rotary cams driven from the door operating linkage for effecting automatic variation in the motor operating speed. In the closed position of the door a hand operated switch 75<SP>1</SP> is open, the armature members 74, 75 of the relay make contact with terminals 76, 77 respectively, switches 60, 62 are open and switch 64 is closed. Current thus flows through the field winding 16, a resistance 81 and the armature winding 52,53 from brush 51 to brush 50, the motor developing sufficient torque to hold the door closed. On switch 75<SP>1</SP> being closed, the relay coil 73 is energised to move the members 74, 75 into contact with terminals 78, 79 respectively. Current then flows through the field winding, switch 64 and the armature winding from brush 50 to brush 51 to operate the motor in the door opening direction. Switch 62 closes when the doors have turned through 10 degrees, and, at 67¢ degrees turning, switch 60 closes to shunt the armature through a resistance 71, thus reducing the speed of the motor. At 85 degrees turning switches 60 and 64 open to put a resistance 82 in series with the armature, the doors encountering stops at 90 degrees, when current continues to flow and the motor develops sufficient torque to hold the doors open. Closing movement is initiated by opening the switch 75<SP>1</SP>, current then flowing through switch 62. The latter opens 10 degrees before the doors reach their closed position to put resistance 81 in series with the armature. Since the latter is shunted throughout the closing movement by a resistance 72, the doors close at a speed which is lower than their speed of opening.

Filed: 1960-08-16
Abstract: 936,743. Making cartons. A. E. REED & CO. Ltd. Aug. 16, 1961 [Aug. 16, 1960], No. 28400/60. Class 18.  Blanks of the kind having a base panel 6 to which are hinged walls 8 are fed through an aperture 3 and located by pins 37 to rest on four platforms 19 one at each corner of the panel base 6, and a pedal 32 is depressed to lower through rod 29 four grippers 26 to clamp the blank at the corners of the base panel. Continued downward movement of the pedal moves the platforms 19 relative to fixed mountings 22 causing flap members 20, 21a at the corners to turn through 90 degrees to erect the walls 8 of the blank, Fig. 3. Tapered blocks 39 urge the gusset corner pieces of the blank inwardly and thin fingers on the flaps 20 tuck the gussets into a position parallel to the erected walls 8. Each flap member 21a carries a further flap 21b operated by links 61 to fold the outer part of the walls 8 through 180 degrees on to the inside of the erected wall, with the gussets 9 between them. Upon release of the pedal 32 the mechanism returns to its starting position the erected carton being deflected by stoppers 42 to fall out of the outlet 13 on to a conveyer. The corner platforms can be adjusted to erect different sized boxes by beams 14, 16 having holes 15, 17. The apparatus can be used for cartons in which each wall is of single thickness and the corners secured by overlapping tabs stapled or stuck to the walls.

Title: Frequency discriminator
Inventor: LAPORTE EUGENE FRANCIS
IPC: G01S13/58
Filed: 1965-07-05
Abstract: 1,077,429. Frequency discriminators; automatic frequency control systems. NORTH AMERICAN AVIATION Inc. July 5, 1965, No. 28404/65. Heading H3A. A frequency discriminator comprises a bridge circuit to which an input is supplied at terminal 10, terminals 18 and 19 being connected through oppositely poled rectifying paths 21a, 21b to an output terminal 11. The arms of the bridge between terminals 10 and 12 are tuned to different frequencies and between these frequencies the output voltage is linearly proportional to input frequency. When the input is above this frequency range, capacitor 13 presents a low impedance between terminals 10 and 18 and the output is a constant positive voltage (Fig. 4, not shown); when the input is a low frequency, inductance 16 presents a low impedance between terminals 10 and 19 and the output is a constant negative voltage. Limiter diodes 28 present excessive response of the discriminator outside its normal range due to harmonics of an input signal. The discriminator may be used in an A.F.C. system for controlling the frequency of the transmitter or the local oscillator of a pulsed radar system, Figs. 5 and 6 (not shown). The output of the discriminator comprises pulses which are fed to a bi-polar integrator (41, shown in detail in Fig. 8) controlling the transmitter or local oscillator frequency.

Title: Improvements in and relating to printing machines
IPC: B41F27/02
Filed: 1925-11-11
Abstract: 264,956. Trist, A. R. Nov. 11, 1925. Printing - surfaces. - In printing - machines equipped with electromagnets for holding a printing-plate, the poles are subdivided into areas of such dimensions that the magnetic fields between adjacent poles of opposite polarity are capable of securely holding a thin printing-plate, for instance, a printing-plate, fifteen-thousands of an inch thick. The Figure shows a flat or cylindrical bed a formed with a large number of ribs or pole pieces c which are separated by grooves b receiving windings e arranged so that alternate pole pieces are of opposite polarity. To provide a flush surface the spaces above the top windings may be filled with composition or fusible metal. In a modification the bed is formed with grooves arranged at right-angles to provide a large number of pole pieces, the windings passing, round three sides of each pole piece in such a manner that each pole piece is surrounded by four pole pieces of opposite polarity. Instead of forming the pole pieces integrally with the bed they may be built up, and the windings may be associated therewith before assembly. In use. a flat or cylindrical printing- plate is placed directly on the pole pieces and is secured by merely energizing the electromagnets. The electromagnets correct small irregularities in the printing-plates. A flexible printing-plate may be bent round a cylindrical bed and have the abutting edges secured together. The printing- plates are of uniform thickness and may be formed entirely of magnetic material or may consist of a printing-surface attached for instance by electro-deposition to a sheet of magnetic material.

Title: Automatic stove selection system for blast furnaces
IPC: C21B9/10
Filed: 1966-06-24
Abstract: 1,139,747. Thermal regenerators. S. P. KINNEY ENG. Inc. 24 June, 1966 [5 Jan., 1966], No. 28487/66. Heading F4K. An arrangement for selecting in a multistore blast furnace installation, the hottest of a plurality of stoves comprises means 23 sensing the temperatures of the stoves and generating an electrical signal indicative of the temperature of each stove, means (such as a detecting relay 26, Fig. 3) for comparing the signals and producing an output signal indicative of the hottest of the stoves, and means (such as a selective relay SR-I, II, or III, Fig. 3) responsive to the output signal for establishing as the stove next to go ON BLAST the stove whose temperature produced the output signal. In an arrangement described for three or more stoves, the signals from a first plurality (less than the total number of stoves) are first compared; then the hottest of these is compared with the remainder; and finally the hottest of these latter is selected as the stove to go ON BLAST In the three-stove arrangement shown, 10 is the blast furnace bustle pipe and I, II and III are the stoves. A temperature sensing device 22 in the hot blast main 17 maintains a preselected temperature of blast passing to the furnace, by regulation of the cold blast throttling valve CBTV to the stoves and a mixer valve MTV in a stove-by-pass line 15. When the stove in use is at its hottest the throttling valve CBTV is only partially open and the mixer valve MTV is fully open. As this stove becomes cooler the throttling valve is gradually opened to its fully open position and thereafter the mixer valve begins to close until substantially all of the blast air is passed through the stove via main 13. Ultimate closure of the mixing valve MTV closes contacts (25, see Fig. 3) on said valve and initiates the selection sequence to bring another stove into use whilst the former stove is put into the ON GAS condition for reheating. The selection circuit (24) remains energized until reopening of the mixer valve MTV and consequent opening of the selection initiating switch (25). A conventional snort valve is provided as shown to relieve the pressure of the blast entering the furnace if an emergency occurs in the furnace.

Title: Improvements in or relating to gauges
IPC: G01B3/18
Filed: 1919-09-19
Abstract: 156,057. Smith, J. C. Sept. 19, 1919. Linear-dimension gauges of screw micrometer type, provided with indicator dials, have the movement of the thimble transmitted to the dials through trains of gearing employing 'elliptical wheels, so that when transfer occurs the periphery of the driver is moving at maximum speed, the transfers occur quickly, and back-lash is taken up. The gearing and indicating-discs are contained in a casing 2 having two lugs 3 to which the shoe 4 for the fixed anvil is attached. Interchangeable shoes 4 are provided and the fixed anvil is screwed to receive detachable anvil heads 70 to vary the range of the instrument. The adjustable anvil 9 is screwed at 11 and is operated by a thimble 19 through a spring ratchet device which slips on excessive pressure taking place between the anvils and the work. The spindle is surrounded by a sleeve 12 fitted with two keys 22, 23, this sleeve being in turn surrounded by two short sleeves 25. Mounted on the sleeves 25, 25 are two indicating-dials 33, 34 secured to extra tubes 34a to permit of angular adjustments. The extra tubes are locked in position by nuts 30, and carry toothed pinions 35. The spindles for the various indicating-discs, and the short sleeves are mounted between the partition 5 and the ends of the casing. Two sets of elliptical gears and indicating-discs are shown, one adapted for inches and one for metric units, the necessary slight difference due to both sets being operated from the same screw being compensated for by the key 23 engaging a helical groove 28 in the sleeve 25, the groove in the other sleeve being straight. The spindle 37 carries a spur-wheel 47 and an elliptical wheel 48 which gears with a similar wheel on the next spindle. A disc 50 with a tooth gap transfers to the wheel 51 and next higher disc, and so on. A clamping-nut 80 may be provided to engage a screwed and split boss 5 on the casing and thus lock the instrument for repetition work. A glass cover is provided suitably darkened except at the windows where the indicating discs are read, such cover being secured by screws and sealed against tampering. In a modification, the fixed anvil is mounted on a spherical joint. Specifications 6590/93, 2878/20, and 155,894 are referred to.
