Title: Apparatus for casting chocolate
IPC: A23G1/20
Filed: 1946-10-24
Abstract: 650,678. Chocolate - casting apparatus. AASTED, K. C. S. Oct. 24, 1946, No. 31620. [Class 87 (ii)] Chocolate is cast into. moulds carried on a conveyer from one or more mouth-pieces 27, by causing a piston 23 to be moved into a cylinder 24 to express chocolate from a mouthpiece. The piston is moved by a mechanism driven from cams 1, 2 that are moved in synchronism with the conveyer and preferably by its driving motor. The mechanism allows the casting quantity and casting length to be adjusted during working. The cams 1, 2 oscillate a shaft 10 which oscillates a shaft 15 through links 12, 35. One end of the shaft 15 has a slotted sector plate 16 in which a pin 18 slides. Movement of the plate 16 causes an arm 19 to be moved horizontally, and the piston 23 to be reciprocated in the cylinder 24. The slot is shaped in three parts : a circular part 28 which causes no movement of the piston and spiral parts 30, 29 ; the part 30 causing a quicker movement of the piston than that caused by the part 29. This quicker movement causes a thickening of the chocolate at the front of the mould. A similar thickening is caused at the back of the mould by projections 31, 32 on the cams. The angular rotation of the shaft 15 relative to that of the shaft 10 is adjusted by a block 33. This adjustment causes the length of travel of the pin in the slot to be adjusted and so adjusts the quantity of chocolate cast per unit time. The length of the cast is adjusted by a block 36 which determines the position of the pin in the slot, when the plate begins its rotation. Two series of mouth-pieces may be used, each series casting in to every second or third mould. When the latter arrangement is used, the conveyer is moved at double speed, so that two moulds are carried on for each casting operations. Each set of mouth-pieces may successively cast in each mould to produce two short bars in one mould.

Abstract: 485,626. Thermionic valves. RUDKIN, E. P. Nov. 20, 1936, No. 31774. [Class 39 (i)] A thermionic valve arrangement comprises an evacuated envelope within which are arranged a rectilinear cathode, a control electrode, a main anode 2 an auxiliary anode 3, the control electrode comprising parallel plates 1 electrically connected and arranged at rightangles to the length of the cathode 4, so as to divide the electron stream into a plurality of striµ. The anode 2 consists of a number of parts, preferably in the form of cylinders, and each part has a surface parallel to the cathode and normal to the adjacent control electrode part, which is preferably in the form of an annulus and is arranged in a plane which passes medially through the corresponding anode part. The auxiliary anode is situated beyond or between the main anode parts, and it may consist of a cylinder to which the main anode parts are insulatingly attached or it may be in the form of a wire mesh. A screen grid 6 having its wires arranged opposite the control electrode parts may be provided; other grids may be arranged similarly between the cathode and control electrode and/or between the latter and the anode, for reducing the anode impedance of the valve. The control electrode serves to vary the current to the main anode parts by both deflection and intensity control of the electron striµ and the arrangement may be used as an amplifier, in which case the main anode parts are preferably several times wider than the corresponding auxiliary anode parts. In a modification, suitable for use as a super-heterodyne mixer valve, there is provided a second electrode forming the injector electrode and comprising a series of plates, which are arranged similarly to and in line with the plates of the control electrode and are situated between this electrode and the anode. Screen grids inserted between the electrodes reduce the internal impedance and inter-electrode capacity of the valve, and auxiliary focusing electrodes, in the form of plates provided with rectangular apertures, may be arranged adjacent the cathode so as to assist in the formation of the electron striµ which are directed against the edges of the control electrode plates. In addition, the cathode may be rendered emissive only in those parts adjacent the apertures in these auxiliary electrodes. Variable-mu characteristics may be imparted to the device by suitably shaping the main anode parts 2.

Abstract: 791,988. Seaming. MINING ENGINEERING CO., Ltd. Oct. 16, 1956 [Nov. 10, 1955], No. 32148/55. Class 42 (1). [Also in Group XXVIII] The edges 16, 17 of a strip of synthetic thermoplastic or synthetic thermoplastic impregnated fabric such as hessian are overlapped to form a tube which is placed in flattened condition between the electrodes of a high-frequency welder with a strip of non-synthetic plastic inactive material between the overlapped edges and the opposite wall of the tube, the electrodes are urged together and current is supplied to weld the edges together. Inactive material is defined as material which is not affected by the welding temperature and does not react chemically with the material of the tube at that temperature; Empire cloth is an example. The use of the inactive strip 18 prevents the edges from welding to the opposite tube wall when the vertically movable electrode 21 is clamped down on the material. When the weld has taken place, the electrode 21 is raised and a fresh length of material brought under it so that the process can be carried out for an indefinite length of tube. In a modification the welding is continuous, the electrodes being in the form of wheels or rollers.

Title: Improvements in or relating to apparatus for stunning animals for slaughtering
IPC: A22B3/02
Filed: 1956-10-23
Abstract: 846,704. Slaughtering appliances. REMING- TON ARMS CO. Inc. Oct. 23, 1956 [Dec. 27, 1955], No. 32287/56. Class 5(1). [Also in Group XXI] A pistol for stunning animals prior to slaughtering is of the captive-bolt type, the bolt 18, Fig. 1, having at its forward end a non-penetrating striking element 4 and being secured at its rear end to a captive piston 17 adapted to be driven forward within the barrel cylinder 3 by the firing of a cartridge 13. Carried on the barrel 3 is a contact trigger 5 connected by a resilient link 6 to the trigger unit 7 of the breech action 1 which is of the convential bolt action type. An elongated handle 8 is attached to the pistol by a multileaf spring 9 capable of cushioning the recoil forces. In addition, at the time of engagement of the trigger 5 with the animals skull, the pistol has considerable forward momentum which also assists to minimize the recoil force. Supported on the piston rod or bolt 18 is a shock absorbing device 20 comprising an assembly of metallic washers having confined between them one or more layers of material such as a woven fabric, e.g. nylon, impregnated with an elastic polymer, e.g. neoprene. The barrel head 10 is formed to define a cartridge chamber 12 joined by a passage 14 with a primary cylinder 15, the barrel 3 comprising a secondary or expansion cylinder. The piston 17 also comprises a primary piston 16 received in the primary cylinder 15. This arrangement provides an initial low expansion rate and consequently high pressure to ensure the quick and complete burning of the cartridge powder. In securing the desired stunning effect with minimum damage to the brain, area contacted by the striking element 4 should vary in inverse proportion to the structural strength of the animal's skull and the kinetic energy applied should vary in direct proportion to this strength. In a modification shown in Fig. 5, the barrel head 31 is in the form of an elbow which positions the cartridge chamber and action unit at a right angle to the barrel unit 3, the handle 37 being secured to a sleeve 33 secured to the action unit 1. The contact trigger 39 is joined by a toggle link 45 to the trigger unit 7, which is operated as the trigger 39 is moved rearwardly.
