Abstract: 1451582 Spot-type disc brakes; automatic regulation by load INVENTIO AG 31 Oct 1974 [2 Nov 1973] 47133/74 Headings F2E and F2F A brake assembly intended for passengerconveying apparatus comprises a rotatable shaft 1 connected to a motive power unit 2, a first brake element e.g. disc 3 mounted to rotate with the shaft, at least one further brake element (as shown, two brake shoes 4.11, 4.21) operated for braking by a spring 6, a device 9 actuatable to counteract spring 6 and connected thereto by a rod 7, a pivotally mounted control lever 11 acting through a second spring 12 on the rod 7 and a retardation-sensing device 13 which is connected between shaft 1 and the control lever to cause the control lever to act on the rod 7 to counteract spring 6 and thus to reduce the frictional engagement between shoes and disc, e.g. by spring 4.3. As shown, the retardation-sensing device 13 is an inertia wheel 13.2 having two rollers 13.71 each engaging a double-wedge-shaped cam 13.8 on disc 3, the wheel 13.2 being rotatable and slidable on shaft 1 and acting on lever 11 by a non-rotatable dome 13.4 and adjustable bolt 13.5. The applying spring 6 acts through a wedge 7.2 on rod 7, and brake levers 4.1, 4.2. In operation, for running of the conveyor, device 9 is switched on so the brake is released by tension spring 4.3. When constant speed is attained, disc 3 and wheel 13.2 rotate synchronously. For braking, device 9 is switched off, so spring 6 applies the brake via wedge 7.2. The degree of retardation of shaft 1 depends on the load, and above a certain value of retardation, inertia wheel 13.2 rotates relative to the brake disc 3, so lever 11 is pivotted clockwise to reduce the effect of spring 6. The smaller the load on the conveying-apparatus, the greater is the relative movement of the retardation-sensing device 13.

Abstract: 1,083,850. Crystallizing. IMPERIAL CHEMICAL INDUSTRIES Ltd. Nov. 17, 1964 [Dec. 3, 1963], No. 47678/63. Heading B1G. In the building up of a crystalline layer on a cooled surface from a circulating liquid in the form of a solution or melt, control is effected by adding heat to the liquid before reaching the cooled surface in a progressively decreasing amount by means of a heat exchanger and/or by removing heat from the cooled surface in a progressively increasing amount by means of a coolant of decreasing temperature and/or increasing rate of flow. The turbulence of the circulating liquid may be adjusted during the crystallization process. Crystallization may be effected in a plurality of tubes in series or in a bundle of tubes. The cooled surface may be finned. The coolant may be a fluid flowing parallel to the crystallizing liquid or may be a cross flow of air. The crystalline layer may be melted by replacing the coolant by a heating fluid or by direct contact with heated melt of the same composition. A thin crystalline layer may be left to seed further crystal formation. The method may be used to purify naphthalene, parazylene, adiponitrile, or methylcyclohexyl-4-methylphenol. As shown, liquid passes from a feed vessel B through a heat exchanger Q and a pump A to a crystallizer tube C having a jacket D whence it is recycled to vessel B. After completion of a crystallization cycle, coolant is replaced by heating fluid in jacket D and the melt obtained as product in vessel M. Further feed may be mixed with the residual liquid. The residual liquid is eventually passed to receiver O.

Abstract: 1320248 Unstacking, and stacking bricks; grippers AIRCRAFT MECHANICS Inc 14 Oct 1971 [4 Dec 1970] 47925/71 Headings B8C and B8H Grids 16 of bricks are unloaded from kiln cars 10, 11 by grippers 33 and fed to a spreader table 43 where the bricks are separated into spaced rows 56 which are fed to a stacker 57. There are two grippers 33, each gripper being vertically movable in a carriage 27 which can be reciprocated transversely of a conveyer 19 in another carriage 22 which can be reciprocated parallel to the conveyer. Each gripper lifts two layers of bricks at a time on to the conveyer and can be rotated through 90 degrees so that each pair of layers is aligned in the same direction on the belt. A plate 41 pushes each pair of layers on to the table 43 consisting of bars 43a which can be spread about to separate the rows. A frame 46 having an inflatable gripper along one side grips the upper layer of bricks on the table, laterally shifts the upper layer with respect to the lower layer to break any bonds between the layers, and swings the layer on to table 48 by the side of table 43. Actuators 53 and 54 pushes the separated rows on to conveyer belts 49 and 51. At the stacker a plate 70 is positioned on a platform 61 which is progressively lowered as the stacking proceeds. A carriage 66 has inflatable grippers which can extend into the gaps between the rows 56 to grip the bricks at the end of each row and transfer them to the stacking position where a stack for each row is formed. In some layers voids are left for the forks of a lift truck. Boards 73 are positioned over the voids. Separation papers 71, 72 may be positioned between certain layers. The plate 70 can be reciprocated by a chain to move the stacks to a feeder 74 where another plate 76 movable along a closed path is lowered behind the stacks. Withdrawal of the plate 70 causes the stacks to bunch up against the plate 76. The plate 76 pushes the stacks to a strapper.
Patent GB-481920-A (GB)
Abstract: 481,920. Cash registers. GLEDHILL, A. H. Nov. 21, 1936, Nos. 31905 and 32461. [Class 106 (i)] Autographic arrangements ; taking totals and subtotals.- In a cash register having means to ensure that the amount in the cash drawer shall be recorded prior to the printing or indication of a total or subtotal, and in which the amount is noted on a card and the card inserted into one of a number of compartments to which access may be obtained in succession, the insertion of the card disables locking means that normally prevents the taking of a total or subtotal. The invention is described as applied to the key set and operated machine forming the subject-matter of Specification 368,785, provided, as described in Specification 459,802, with a member A, Figs. 1 and 2, divided into sectoral cardreceiving compartments and rotated step-by-step upon the taking of totals or subtotals to position the compartments in succession beneath a slot a<9>. Means are now provided to lock the total or subtotal taking means until a card has been inserted in the compartment situated beneath the slot. In the embodiment shown, the known finger-retractable detent K, for locking the total-taking crank shaft O, is held in locking position by a hook g<2> that takes over the right-hand arm of a lever H linked to the detent. The hook forms part of a lever G pivoted on a stud g<1> and urged counterclockwise into effective position by a spring F, in which position an arm g of the lever presses a feeler e<2> through an aperture in the casing and into the compartment to which access is given by the slot a<9>. Now upon the insertion of the card, the feeler is rocked about its pivot e and in turn rocks the hook clockwise to free the lever Hand thus permit the shaft O to be unlocked by manual movement of the detent K. A subtotal or total may now be taken depending upon which of two removable conditioning keys n, n<1> is rotated in its appropriate lock. During this operation, the compartment is moved away .from the slot and the card away from the feeler, thus presenting an empty compartment beneath the slot and resetting the locking mechanism. In a modification, instead of locking the detent K, the lever G co-operates with an extension of the threearmed lever n<3> that is rocked by the total and subtotal conditioning keys n, n<1>. The lever G may be shaped to prevent movement of the three-armed lever in either direction, in which case both total and subtotal taking is prevented until a card is inserted, or clockwise movement only of the three-armed lever may be prevented in which case a total may be taken in the absence of a card.

[Also in Division G1] A billet inspection station comprises a conveyer for delivering the billet to a magnetizing and particle applying position and apparatus for transferring the processed billet to an inspection position, the latter position including apparatus for rotating the billet about its own axis, whereby the whole of the periphery may be inspected, and unloading apparatus. The conveyer comprises rollers 14-20, Fig. 1, which bring the billet to a position overlying hydraulically operable swingable loading arms 23, 24, 26, 27, 28 which have skid rails 38-42 on their upper surfaces whereby a delivered billet B, Fig. 2, is slid into a position B1 in which it rests in notches 43, 44, 46, 47, 48. In this position the billet is connected to a power source by a fluid-operated contact 49, and a contact 52 on a tailstock assembly, and the resulting current therethrough effects substantially uniform magnetization. Magnetic particles are then applied from a bath 54 which is swung back and forth over the billet for a predetermined period of time. After backing off of the contacts, swingable unloading arms cause the billet to be lifted and slide through a position B2, and lifted by further feed arms 80-84 to a position B3, from which it can be slowly lowered by arms 91-94 and 96 on to chain slings 103 which enable it to be rotated under the control of an inspector on platform 104. The height of the chain cradle is adjustable and the chain is driven by an electric motor through a further chain and sprockets. The arms 91-94 and 96 serve also to discharge the billet on to rollers 118-124. Intermediate arms 107-111, which are moved at a slow speed, prevent damage when the billet engages the rollers. Separate electric motors are provided for delivery, discharge and rotation during inspection; and the hydraulic pistons which move the various arms are sequentially controlled by motor driven cam-operated switches actuating supply valves. The current may be disconnected when the particles are applied. In an alternative arrangement the billet may be delivered to the run-out rollers from the magnetizing position and be lifted therefrom by the chain cradle for rotation.

Abstract: 1370339 Vehicle uncoupling GERMANY MINISTRY OF TRANSPORT 21 Oct 1971 48984/71 Heading B7N In a system for selectively uncoupling vehicles on a train from a central position on a traction unit, uncoupling is controlled by first disconnecting a continuous signal from a first intervehicle line circuit and then applying a number of pulses equal to the number of the coupling to be actuated, as counted from the traction unit, to a second inter-vehicle line circuit. Each vehicle is provided with arrangements which on reception of a pulse initiate an uncoupling action via a circuit having a delay greater than the interval between pulses and prepare a circuit to the next vehicle along the train. The following pulse if received cancels the uncoupling action and is transmitted to the next vehicle and where it starts a similar action. Two arrangements are provided on each vehicle, one for each coupling, the arrangement associated with the coupling facing away from the traction unit being brought into use. After the uncoupling action the circuits in the still coupled vehicles are restored to their initial condition by reconnecting the continuous signal to the first line circuit.
