Patent GB-494792-A (GB)
Title: An improved receiving device for an electric remote control system
IPC: G04C11/00
Filed: 1937-10-16
Abstract: 494,792. Electric control systems. LANDIS & GYR AKT.-GES. Oct. 16, 1937, No. 28222. Convention date, Dec. 24, 1936. [Class 40 (i)] A selective receiver for use on an A.C. network of the type wherein selection is determined by the time interval between interruptions of the network current comprises a selector switch 1 having a contact arm 2, driven by a synchronous motor 7 which normally is open-circuited over a switch 8, and being capable of closing a circuit over one or other of the relay windings 16, 17. Normally with voltage on the network A, B, the switch is in the position shown and relay 12 is locked energized over relay contacts 19, 13. Upon an interruption of the network current, relay 12 releases and prepares a circuit over the arm 2 for the driving motor 7 which starts up when the network current is re-established and closes a maintaining circuit over the switch 8. The switch is thereby rotated and when the arm 2 engages contact 9, relay 12 is again locked energized and the arm 2 is cut out of circuit. A subsequent interruption stops rotation of the switch and releases relay 12 to prepare a circuit for the winding 16 or 17 over contact 14 or 15 the selected winding being energized when the interruption is terminated. Subsequently relay 12 is again locked energized, e.g. over contact 10 or 11 and just prior to the restoration of the switch, to its normal position, the motor circuit is opened by the switch 8. In a modification, the relay 12 is replaced by a slow-acting relay permanently connected to the network ; this avoids the use of the contacts 9, 10, 11. Instead of effecting selection and operation by a single final interruption, two or more interruptions may be used in combination.

Title: Operating device for mechanical grabs and digging machines
IPC: E02F3/30
Filed: 1957-09-06
Abstract: 870,258. Grab excavators. HELLSTROM, G. H. Sept. 6, 1957 [Sept. 11, 1956], No. 28240/57. Class 68(1). [Also in Group XXX] The effective length of the operating cables of a grabbing crane or digging machine is varied by passing the cables round pulleys which are movable towards or away from each other, the arrangement being such that at least two cables are varied simultaneously by their pulleys being attached to the same movable parts, and at least one of these cables is separately variable by a similar arrangement of movable pulleys. As shown in Fig. 1, a grab bucket 12 which is opened by shortening cable 20 and closed by cable 21, is raised and lowered by simultaneously shortening or lengthening cables 13, 20 and 21, and a carriage 6 carrying the bucket is moved along a jib 5 by simultaneously shortening cables 13, 20, 21 and 29 and lengthening cable 28, or vice versa. These movements are achieved by the apparatus shown diagrammatically in Fig. 2, in which cables 13, 20, 21 and 29 are simultaneously shortened by admitting fluid into a cylinder 35, cable 28 at the same time causing pistons 52 and 53 to eject fluid from cylinders 51 by virtue of the pull applied to the cable by the movement of the carriage 6 from left to right in Fig. 1. Alternatively, the piston rod 71 may be formed as an extension of the rod 38 and the rods 39, 72 fixed to their respective cylinders, so that as the piston 36 moves outwards, piston 52 moves inwards and vice versa. Cables 13, 20 and 21 can be simultaneously shortened by admitting fluid into cylinder 57, and cables 20, 21 can be independently operated by cylinders 69, 70. A digging machine is illustrated (Fig. 5, not shown) to which the same method of operation is applied.

Title: Improvements in or relating to data readout apparatus
IPC: G06K7/015
Filed: 1964-07-08
Abstract: 1,074,545. Sensing records, HONEYWELL Inc. July 8, 1964 [July 8, 1963], No. 28243/64. Heading G4M. A magnified image of two tracks A, B of printed code bars on a document is sensed by photo-cells 1-18, output signals from groups of five cells being selected according to the amount of misregistration of the tracks with the sensing station. The amount of misregistration is determined by cells 13-18 and gating circuits 58. With correct registration, cells 16-18 sense a blank area and cells 13-15 sense code bars to produce an A.C. output. When the registration is incorrect the numbers of cells sensing the blank area and the code bars are different. Registration detector circuit 58 produces an output on one of six leads to indicate that registration is correct, 1 or 2 cells down or 1, 2 or 3 cells up. Diode gating matrices 60, 61 are controlled by the output of detector 58 to pass only the outputs from the group of five cells which is centred on the tracks A, B. For normal registration the outputs of cells 3-7 and 10-14 are selected. Further diode matrices 66, 70 select the signals which are present at the majority of the inputs (i.e. 3 or more), and also reject signal groups which are likely to have been derived from mutilated marks.

Title: Improvements in or relating to athletic implement matching device
IPC: A63B59/00
Filed: 1952-11-12
Abstract: 712,029. Determining centres of gravity. SPALDING & BROS., Ltd., A. G. Nov. 12, 1952 [July 9, 1952], No. 28566/52. Class 97(3) A device for matching golf clubs or other sports implements with respect to their centres of gravity comprises members spaced apart at an angle to each other for engaging the ends of an implement, a balancing member so placed between the end-engaging members as to be engaged by the implement at its calculated centre of gravity, and means causing the located implement to be brought into engagement with the balancing member to be freely supported thereby. As shown, an end-engaging plate 15 and a member 11 comprising a head-engaging bar 20 connected by a slotted link 21 to a bar 18 are pivoted at 17, 22a to base members 13 which pivot on plates 13a, slidable along a base 12. A balancing edge 23, which may be straight as shown or curved if necessary to include the points at which the calculated centres of gravity lie, is adjustable in slots 12a in base 12. A carriage 26 travelling on rollers 27 on a track 25 secured to base 12 has a cradle 29 with notched ends 30 carrying the club. The cradle being mounted on an arm 31 pivoted to the carriage at 32 and urged upward against a stop nut by a spring 35. A club is placed on the cradle and carriage 24 is moved until the ends of the club engage the members 15, 20, which are held upright by spring-pressed plungers in cylinders 39, 40. Arm 31 is then depressed by a handle 37. This lowers the club on to the edge 23, and also operates a ratchet switch to energize a solenoid hydraulically connected to cylinders 39, 40, so that the plungers are withdrawn. Members 15, 20 swing down as by gravity or a spring 54, leaving the ends of the club free. Just before these members operate, a piston 48 of a cylinder 47 also connected to the solenoid is pushed out to move an elongated pivoted brake member 45 into engagement with carriage 24, which is thus held. The club then rests on the edge 23, which is of small radius and covered with rubber. The angle of the club is noted, or it is balanced horizontally by adding weights, so that it may be adjusted afterwards to balance at a chosen point. The length of the club may be read by noting the position of the carriage with respect to a scale 57 on the track 25. A second depression of arm 31 operates the ratchet switch again, to release the carriage and to return members 15, 20 to their initial position. If desired, the brake may be actuated separately before arm 31 is depressed.

Title: Improvements in and relating to the coating of confections or the like with sugar orlike material
IPC: A23G3/20
Filed: 1931-10-14
Abstract: 391,121. Coating confections with sugar &c. BAKER PERKINS, Ltd., Hythe Road, Willesden, London. Oct. 14, 1931, No. 28585. Convention date, Jan. 12. [Class 28 (i).] Confections are coated with sugar or the like by affording them a trajectory or free fall into or through a shower of coating material whereby they become coated in their flight. This coating may comprise the complete coating of the confections, or may be a preliminary to a secondary coating in the usual mixing drum. The individual coating of the confections whilst in the air prevents them from sticking together and producing scrap as is usual. In Fig. 4 the confections are carried on a conveyer 9 through a moistening chamber and are dropped into the mixing drum 1 through a shower of sugar projected from a nozzle 14a in communication with the sugar supply hopper 8a and the fan 15. The mixing drum 1 has an unperforated end 1a and helical flights 2 which lead the confections to a perforated part of the drum through which excess sugar drops into a collecting receptacle from which it is elevated by a bucket conveyer and re-delivered to the hopper 8a. In Fig. 5 the confections are delivered from the conveyer 9 on to a high speed rotary roller 11 which projects them substantially horizontally through the sugar shower S<11> on to a screen 16 through which excess sugar drops. In this case the coating is completed as the confections pass through the shower. In a modification in which a rotary mixer 1 is used, the sugar is allowed to drop from a hopper projecting into the end of the drum and the confections are thrown through the shower by a high speed roller 1] positioned close to the conveyer 9. Instead of a single shower, a number of showers may be used and the shower may be produced by a perforated rotary drum, or by projecting the sugar upwardly from the mass in the mixing drum by means of compressed air. Alternatively, the mixing drum may have baffles which lift the sugar from the lower parts of the drum and drop it over the entering confections.

[Also in Division A2] A method of regulating a continuous process machine comprises the steps of measuring a characteristic of the product, generating first and second signals (by switches 8a, 8b) when the characteristic exceeds upper or lower limits respectively, generating a further signal when the algebraic summation of the times during which said signals have been generated exceed a predetermined value, and applying correction when this further signal is generated. The summation is effected by cams 10...12 which are driven one way or the other by a motor 9 according to whether switch 8a or 8b is closed. When the error has persisted long enough for switch 13 or 14 to be actuated warning lamps are lit and either an operator or a servomotor applies correction. A thermal timer 30 is also started which stops the machine if it times out. The cam motor is automatically re-set. Applied to a cigarette rod machine the detector comprises a feeler actuated by the level of tobacco in a stream after "equilization".
