Abstract: 698,433. Making ice cream sandwiches. ROSE BROS. (GAINSBOROUGH), Ltd. Jan. 29, 1952 [Jan. 30, 1951], No. 2293/51. Class 28 (i). [Also in Group II] Ice cream sandwiches are made and passed to a wrapping machine by dropping the lowermost of a stack of wafers 16 into each pocket 14 conveyed e.g. by a chain conveyer 11 under a support station where cutters 43 cut off a piece from an ice cream block 41 to drop on the wafer, and further conveying under a second wafer magazine 48 to receive a top wafer. The sandwich then pases to one of the pockets 51 of a rotary device 49 which delivers it to known wrapping mechanism. Wafer delivery.-The wafers in the magazine 16 temporarily rest on a support 38. A side presser 27, actuated by a cam 31 in timed relation to the step by step conveyer chain, presses the stack of wafers except the bottom wafer frictionally against the side of the magazine 16 after which the magazine and presser is reciprocated up by cam 26 leaving the bottom wafer on the support 38. A reciprocated pusher 39 pushes the bottom wafer sideways to drop through a slot 37 into the pocket 14.

Title: Improvements in dividing heads
IPC: B23Q16/04
Filed: 1943-02-16
Abstract: 562,818. Dividing-engines. LEWIS, W. W. Feb. 16, 1943, No. 2513. [Class 97 (iii)] [Also in Group XXII] A dividing-bead capable of carrying a work piece whilst being machined or shaped, has an index plate carrying a projecting pin adapted to engage a stationary stop for determining angular displacements of the work, the pin being inserted in any one of a series of spaced notches on the plate for giving a course adjustment and the stationary stop being tangentially adjustable to give the fine adjustment. The index plate 1 is rotatably mounted in a bracket 3 by means of a shaft 2 secured thereto and is provided with notches 6 spaced 30 degrees apart around the periphery, each notch having mutually perpendicular sides 6a, 6b to which the pin 7 is attached by a screw 8a. The pin has a cylindrical portion 7b adapted to engage the end of the stop 9 adjustably held in a split clamp 8 on the bracket 3, and a screw 13 also carried by the bracket 3 in a split clamp 14 may be used to hold the pin 7 in contact with the stop 9. A micrometer 10 carried by a clamp 12 on the bracket 3 engages the end of the stop 9, and in operation, the micrometer is set at zero and the length of the stop 9 is arranged so that its end face in contact with the pin 7 will lie in a plane perpendicular to the axis of the stop and passing through the axis of the shaft 2. To displace a work-piece attached to the plate 1 through an angle of more than 30 degrees, the plate is rotated and the pin 7 is moved to the appropriate notch 6. The stop 9 is then adjusted by the micrometer to give the final setting of less than 30 degrees, the linear movement of the stop being equal to the radius of the index plate up to the centre of the pin 7 multiplied by the sine of the angle through which the plate is to be moved. The plate is then rotated to bring the pin 7 into contact with the stop again, and may be clamped in this position by the screw 13 during machining of the work. The stop 9 may be replaced by others of different length in order to keep the adjustment within range of the micrometer, and gauge blocks may be placed between the stop and an abutment such as the clamp 12 instead of using a micrometer. The bracket 3 may be mounted on a base 16 by means of a shaft 15 perpendicular to the shaft 2, a flange 17a on the bracket being provided with holes 20 to receive a pin 19 coacting with an adjustable stop 9a to give angular adjustment in the same manner as that about the shaft 2, clamping being effected by an arcuate slot 18 on the base 16 and studs on the bracket. The shaft 2 may have a conical bore 21 for receiving a work-supporting shaft or centre and the plate may have holes 22 or other means for attaching dogs or the work thereto.

Title: Improvements in analogue information storage devices
IPC: G01C21/20
Filed: 1961-02-08
Abstract: 985,979. Toothed gearing. MINISTER OF NATIONAL DEFENCE OF H.M. CANADIAN GOVERNMENT. Feb. 8, 1961 [Feb. 15, 1960], No. 2549/63. Divided out of 985,977. Heading F2Q. A memory device for storing analogue information comprises an input shaft 40, a gear-wheel 26 keyed to the shaft, a slotted index element 28 associated with this gear-wheel, a pinion 25 meshing with the gear-wheel, second and third gear-wheels arranged coaxially with the first gear-wheel and independently mounted for rotation in mating engagement with the pinion 25 and slotted index elements 29, 22 associated with the second and third gearwheels. The gear-wheels have numbers of teeth in the ratio of n : n + 1 : n - 1. In addition, a pawl shaft 35 lies adjacent the gearwheels, with pawls rigidly connected to the shaft and each adapted to engage in the slotted index elements, and a switch actuating rod 36 is fixed to the pawl shaft and is adapted to operate one of the switches 41 or 42 when the pawls are out of engagement with their respective indexes. In use the shaft 40 is rotated in accordance with the analogue input signal, turning the index slots away from engagement with the pawls in the rest position, the position in which the system sets representing the information to be stored. To read out this information, a motor (not shown) is energized and drives the shaft 40 in the required sense, as indicated by which of the switches 41, 42 is engaged, until the slots 30, 31, 23 are aligned so as to permit the pawls to fall back into place and open whichever switch has been closed. In order to avoid hunting a disc may be provided on the shaft 40 with an indentation which may be engaged by an armature from a brake when the switch opens, thus preventing any inertial rotation of the memory wheels.

Title: Induction heating systems
IPC: H05B6/02
Filed: 1956-01-26
Abstract: 821,626. Heating by induction. MAGNETHERMIC CORPORATION. Jan. 26, 1956 [Jan. 27, 1955], No. 2604/56. Class 39(3) [Also in Group XXXV] An induction heater for metal workpieces comprises a liquid-cooled inductor winding 5 having taps for connection of the secondary windings of three singlephase transformers fed from a delta connected three-phase supply. A metal tube 6 which may be double walled, is of non- magnetic and high-temperature resistant material, e.g. stainless steel, and carries the winding 5, one or more longitudinally extending non-conductive seams 7 preventing flow of current circumferentially of the tube. The connections to the primary winding of the intermediate transformer 23 are transposed and the conductors of each of two pairs of connections a2, b1; b2, c1, between the inductor taps and the transformer secondary windings are also transposed thus forming "phase overlap" zones h1, h2 between the main zones L, M, N of the inductor winding. Fig. 2 shows how the vector of the flux B produced by the current in transformer 23 is rotated through 180 degrees by the transposition of the connections of the primary winding of the transformer 23. The vectors A, BX representing the flux in main zones N, M differ by 60 degrees, and the vector ABX representing the flux resulting from flux A and flux B differs by 30 degrees from A and BX. Similarly, flux CBX produced by flux C and flux BX is 30 degrees removed from flux C and flux BX. The small displacement between successive phases, i.e. 30 degrees, results in substantially uniform heating at a uniform rate of the workpieces. Further, the resulting reduced voltage between adjacent convolutions of the inductor winding avoids the necessity of providing annular spacers of insulating material.

In order to reduce the magnitude and duration of subtransient short-circuit currents in a synchronous alternator without appreciably reducing the damping constant or increasing the voltage drop, the alternator is provided with an auxiliary squirrel cage comprising bars C of low resistance, e.g. copper, each of which is located within a complete sheath or tube S of magnetic material, e.g. iron, so that the effective resistance of the squirrel cage will increase with the frequency of the short-circuit current, i.e. the normal frequency of the machine, which is higher than the frequency of the current which may circulate in the cage due to hunting of the machine. For this purpose the cage bars are accommodated in the pole shoes of the field poles of the machine.

Abstract: 1,099,056. Making laminated cores. GENERAL ELECTRIC CO. Jan. 21, 1966 [Jan. 21, 1965], No. 2812/66. Heading B3A. In order to reduce the electrical losses in a laminated core, the laminations are slightly separated in order to break inter-laminate bonds which are believed to occur during annealing due to the formation of oxides on the facing surfaces of laminations. A method of achieving the separation is described with reference to a stator core 10 built up from laminations 11 which are held together by keys (12), Fig. 2. Inside the core is placed a primary winding 21 comprising four coil groups 36, 37, 38 and 39 which form magnetic poles of alternating magnetic polarity. The coils are supported on a synthetic resin former 31 and are encased in a thermo-setting epoxy resin. The winding is connected to the output terminals 24, 25 of an apparatus which produces a high-energy surge of electrical power. A varying magnetic field is created by the high energy surge distributed around the inner periphery of the core 11 and this produces electromagnetic forces which interact with the laminations to cause movement of adjacent laminations away from one another. The energy surge is produced by charging a bank of capacitors from A.C. mains through a full wave rectifier and discharging the capacitors through the primary winding 21 by triggering an ignitron. The circuit is illustrated and described.
