Title: Improvements in or relating to transfer circuits for electric signals
IPC: A01K1/01
Filed: 1954-06-02
Abstract: 765,974. Non-contact-making relays. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. June 2, 1954 [June 3, 1953], No. 16364/54. Class 40 (4). An arrangement for transferring trains of rectangular pulses from one circuit to another under the control of a D.C. signal comprises a pair of annular magnetic cores 1, 2 each having substantially rectangular hysteresis loops and supporting input and output windings and a control winding, each input winding 3, 4 being energized by pulse trains which are complementary to the pulses applied to the other input winding while the output windings 7, 8 are connected in series opposition with a load 9. By providing a number of core pairs I, II, III having common input circuits, Fig. 1, and selectively energizing the control windings 5, 6 of a single pair, the input pulse trains are transferred to only one of a number of loads which may comprise separate recording heads of a magnetic drum. All the cores are initially magnetized to saturation in the N direction, and since pulses in the input windings 3, 4 are also N-magnetizing, signal transfer does not take place. If, however, a D.C. signal I, is applied to the control windings 5, 6, both cores are magnetized to saturation in the P direction. As the amplitudes of the complementary pulses I c , I c 1, Fig. 2 (not shown), applied to windings 3 and 4, change between zero and I o , N-magnetizing forces are produced in the respective cores which alternate from one core to the other. Induced currents +i a , - i a  are thus produced in the output windings which act alternately in opposite directions due to the opposed connections. The rectangular magnetizing-characteristic determines the uniform amplitude of the induced currents and the output pulses are a replica in form of the input pulse train, provided that the duration of each pulse lies between a minimum and a maximum value. As each core in turn is changed to an N condition by energization of its input winding, the resultant induced current acting in the load circuit and the output winding of the idle core restores that core to a P-condition in readiness for the next pulse. Signal transfer ceases on termination of the control signal. In order to speedily restore both cores to their initial N-magnetizing condition the input currents I c , I c 1 are applied simultaneously to their respective windings. Alternatively an N-magnetizing current may be applied to auxiliary windings (not shown), mounted on the cores.

Title: An improved method of, and apparatus for operating air-blast mills
IPC: B02C23/00
Filed: 1928-06-05
Abstract: 291,726. Hartstoff-Metall Akt.-Ges. June 2, 1927, [Convention date] Pneumatic separating.-In an airblast mill of the kind having a preliminary separator 6 and a dust separator 11 arranged behind the mill 1 with respect to the direction of the blast in a closed circuit, the intensity of the blast from the blower 12 effecting the separation of the coarse from the fine particles is determined independently of the intensity of the blast from the blower 4 effecting the conveyance of the ground material out of the mill. The closed circuit for the mill 1 is 4, 2, 1, 3, 5, 6, 7, 4, and the closed circuit for carrying off the fine particles is 12, 13, one or more of the passages 9, 21, 22, pipe 10, cyclone 11, pipe 14 to blower 12. The material is fed into the mill 1 through the hopper 19 and rotary valve 20, and the coarse particles carried from the mill and deposited in the separator 6 are returned to the mill through rotary valve 16. The separator 6 is provided with passages 9, 21, 22 of which 9 or 9 and 21 may be shut off from the cyclone 11 by flap valves 24, 25. The degree of fineness of the particles conveyed into the pipe 10 is increased by opening both valves 24, 25, and is unaffected by the blast passing through the mill. In a modification, Fig. 2, only one blower 12 is used, the circuit being 12, 7, 2, 1, 3, 5, 6, two or more of the passages 29 - - 33, 10, 11, 14, 12. The disintegrated material in the separator 6 falls upon the oblique bottom 36, the air flowing through a channel 27 into a chamber 28. The material passes, step-by-step, over the passages 29 - - 33 where it is subjected to the action of the blast passing from the chamber 28 into the pipe 10, those particles which the blast cannot carry away falling back into the mill through the rotary valve 16. The velocity of the blast passing through the mill and the pipe. 5 in order to convey the material into the separator 6 is slightly increased by the opening of one or more of the flaps 39, 40, 41 which regulate the degree of fineness of the finished product. The material separated in the cyclone is collected in a vessel 15.

Title: Reversing toy vehicle device
IPC: A63H29/04
Filed: 1936-06-12
Abstract: 472,071. Toys. MARX & CO., Ltd., L. (Marx & Co., Inc., L.) June 12, 1936, No. 16487. [Class 132 (iii)] A toy vehicle having a bumper bar and feelers for causing reversal of driving motor, when a bumper strikes an obstruction or a feeler passes over the edge of the running surface, has power means operable by the motor for positively shifting the bumper bar upon a predetermined displacement of the bumper bar. A toy tractor has bumpers C which on striking an obstacle cause movement of the bumper bar 66 and a slotted member 78 connected thereto to allow a crank pin 76 on the gear 74, mutilated at diametrically opposite positions 82, to move in the slot under the action of a spring 104 bearing against a diametrical arm 110 fixed to the shaft of the mutilated gear which is thus put into mesh with the pinion 80 driven from the motor M, and rotated through half a revolution. The member 78 and bumper bar 66 are thus further moved under power of the motor M to cause a part of the bumper bar bent upwardly at 70 to encompass the shaft 54 to contact with one of the collars 72 thereon and move the shaft to cause the bevelled pinion 52 to mesh with the other side of the crown gear 50 to reverse the vehicle. A stopping and starting lever 96 has a portion 100 adapted to be moved into the path of governor arms 92 driven from the pinion 80. The feelers F are formed of bent wire pivotally mounted at 112 and offset at 114 to underlie the ends 126, 128 of an elongated leaf spring secured to the bumper bar at 30 so that when a feeler F descends the part 114 thereof raises the part 126 or 128 of the leaf spring for the end 132 or 134 thereof to engage the trip gear 122 or 124 to move the bumper bar 66 and initiate the reversing operation as heretofore. The feelers F may be raised to inoperative position, and retained by a flange on the vehicle so as not to interfere with the climbing ability of the vehicle. The feelers may be connected to the reverse gear or to the bumper bar. A simulated operator is formed of sheet metal with the body portion 143 pivoted at 144 to the leg portions 146 and with one arm 148 pivoted to the body at 150 and to the member 78 at 152 so that the operator appears to draw back when the member 78 is moved on the vehicle striking an obstruction or reaching the edge of the running surface. The toy simulates a farm tractor with body B of sheet metal and with wheels W with peripheries V-shaped in cross-section to receive V-shaped blocks 26 of the continuous rubber treads 28, the outer surfaces of which are provided with projections 30 to ensure adequate traction when climbing. The motor M is a spring motor with a square section winding stem 32, one end of which is bent to form a winding key 34.

Title: Improvements in rotary separating mechanism for harvester threshers
IPC: A01F12/00
Filed: 1958-05-22
Abstract: 840,995. Screening apparatus. ALLIS-CHALMERS MANUFACTURING CO. May 22, 1958 [May 31, 1957], No. 16499/58. Class 117 [Also in Group I] A separating mechanism for a harvester thresher comprises a stationary concave sifting grate 18 within a housing 31, a rotary agitator 19 which advances threshed material over the grate from one end to the other end, whereby grain falls through the grate, and a side aperture at said other end for the discharge of straw from the housing, said aperture being associated with a beater element 54 radially offset from the agitator so as to engage the straw and eject it from that aperture. As shown, the separating mechanism forms part of a harvester thresher supplied with power from a power take-off shaft of the tractor which draws it. The thresher includes a header 7 and thresher mechanism 8 from which the threshed material is fed to one end of the housing 31. The agitator consists of a number of helical conveyer flights 89, 91 mounted on angle bars 84, 86 carried by and circumferentially spaced on discs extending from a central drive shaft 78 rotated in the. direction of the arrows, Figs. 3, 6 and 7. At the straw outlet end of the housing the agitator comprises paddles 93 extending radially of the angle bars and producing a rotation of the threshed material. Adjacent those paddles is arranged the beater element 54 located within a straw outlet hood 49 and comprising a rotary shaft 129 with pivotally mounted flail members 161 driven at a higher speed than the agitator. The grate comprises a number of spaced parallel bars 57 supported on curved angle iron girders such as 58 by clamps. A comb structure 162 comprising parallel spaced wires extends downwards from the upper part of the housing and extends the length of the threshing cylinder 9 and allows passage of grain therethrough to the space below the grate. Wire prongs 163 in the mid-section of the housing prevent material conglomerating during its movement towards the straw discharge end. As the threshed material is moved over the grate, grain, unthreshed heads and chaff fall through it to a grain drag 102, comprising a pair of spaced chains interconnected by transverse drag bars 106, and is carried thereby to a tray 98 and fed to an oscillated shoe 96 which, with the aid of a fan 108, produces a separation of the grain from the rest of the material. Clean grain is delivered by a feeder 156 to a shoot 157 and a bin 158, and the tailings are fed by a feeder 148 to a shoot 151. The rotary parts are driven from the power take-off shaft of the tractor via belt and chain gearing. Specification 734,642 is referred to.

Title: Improvements in coin freed mechanism for cigarette, chocolate and like vending machines
IPC: G07F5/02
Filed: 1923-06-27
Abstract: 218,829. Ayliffe, H. June 27, 1923. Delivery of articles stored in piles; coin action, thrust; testing coins.-In a machine for delivering packets of cigarettes, chocolates &c. adapted to receive coins with milled edges, such as sixpences or shillings, in order to prevent operation of the machine by coins or discs having plain edges, a disc 10, Fig. 1, having a serrated or other frictional edge is disposed in alignment with the coin slot 11 and is rotated by a milled-edge coin so that a cranked extension 13 of a longitudinal rod 14 carried eccentrically by the disc is lifted against a spring 16 and allows movement of the drawer blocking-mechanism. This mechanism comprises a spring-controlled lever 7 pivoted at 8 and normally blocking a pin 4 depending from the drawer and working in a slot 5 in a plate 6. The lever is pushed aside to release the drawer by a coin pressed through the slot 11 engaging a knifeedged plate 12 on the forward end of the lever. To prevent the mechanism from being released by rotating a plain-edged disc against the serrated disc 10, the coin once it is inserted is inaccessible by the operator and is pressed through the slot by a pivoted arm 18 provided with a finger-piece 20, Fig. 2. The arm 18 is controlled by an air dash-pot 21 to provide a slow action. The plunger 22 of the dash-pot is connected to a lever 23 having a cam-shaped end 25 bearing against the arm 18. In a modification, Fig. 7, an arm a having a finger-piece d presses the coin through the slot. The arm is returned and maintained in normal position by a coiled spring g anchored to an extension i which, when the arm is moved, passes between leaf springs preventing its return. When the drawer is opened a pointed finger k, Fig. 1, thereon passes between the springs j to release the arm a. The finger k also displaces any coin which may have become wedged in the slot 11. For preventing the insertion of soft discs, the coin is inserted between a block 26 and a front vertical plate 27, Fig. 6. An horizontal plate 28 having a knife edge 20 has to be levered back against a spring 31 by the coin before it can be inserted. Soft discs which would rotate the member 10 would be cut by the knife edge 29. The Provisional Specification describes another means for preventing the use of plain-edged discs. This comprises a pair of lugs upstanding through the coin slot and carried by a pivoted plate engaging the pivoted blocking lever for the drawer and the serrated disc. The serrated disc must be rotated before the lug-bearing plate disengages the pivoted lever.
