Title: Remote central control of cloakroom lockers and other sets of lockable spaces
IPC: E05B47/04
Filed: 1975-09-29
Abstract: 1528571 Remotely-controlled lockers BRUNEL UNIVERSITY 29 Sept 1975 [27 June 1974] 28536/74 Heading E2A A plurality of lockers are connected to a remote control station having a switch for each locker. Operation of this switch activates a solenoid which withdraws the bolt on the respective locker door and permits it to be opened. Opening the door breaks the circuit and, since closing does not reform it, another operation of the control switch is required to re-open the door. This is achieved by the use of single pole changeover switch S 2  on the door and S 3  at the control. If S 2  is in position a-b, then changing S 3  to d-e permits the circuit to be completed and the door to be opened by closing switch S 1 . Opening and closing the door, however, moves switch S 2  to position a-c, so that S 3  must be altered to position d-f for re-opening the door.

Title: Improvements in and relating to cutting devices
IPC: B26D5/16
Filed: 1965-07-06
Abstract: 1,075,722. Cutting apparatus. CARDIOSONICS MEDICAL INSTRUMENTS CORPORATION. July 6, 1965 [July 7, 1964], No. 28572/65: Heading B4B. A device for cutting portions from sheet material, e.g. rolls of graph paper, comprises a continuous cutting blade 106 fitting about a metal block 105, cutting being effected by a pivoted platen 120. The blade, which may be rectangular, is removable and the block is supported on a base 111 by means comprising screws and a leaf spring 113. Adjustment of a screw 117 adjusts the downward limit of the cutting edge and thus the number of sheets which may be cut. The platen 120 is supported on an arm 121 which is engaged by a second support 125 so that the platen may move longitudinally of the device. In operation, a roll of paper is positioned at one side of an adjustable guide (150, Fig. 6) and the free end unrolled until it is located over the cutting blade. A knob 138 is depressed, so that the support 125 pivots about a shaft 129. Recesses 147 in the forward end of the arm 121 engage a pin 146, and the arm 121 slides forward until pins 170 on the arm engage the rear surface 143 of the front wall 100 of the device. Further pressure causes rolls 133 to roll over an arcuate portion 122 of the arm, so that the arm pivots clockwise about a pivot point formed by the pins 170 and 146. The cutting edge and platen thus interact to effect cutting of the sheet. On release of the pressure on the knob, springs 134 cause the rollers 133 to move clockwise, so that the components may return to their original positions. In a further embodiment an alternative spring arrangement for returning the components to their rest position and an arrangement for adjustment of the paper guide are described.

Patent GB-232281-A (GB)
Title: An improved method for extracting or recovering tin from tin bearing materials
IPC: C22B25/06
Filed: 1923-11-15
Abstract: Tin is extracted from tinned scrap or from reduced tin ores by treatment with chlorine dissolved in carbon tetrachloride.  The materials need not be dry, and the scrap need not be subjected to a preliminary treatment except for removal of lacquer or paint since any grease present dissolves in the carbon tetrachloride, and any chlorides other than tin chloride that may be formed owing to the presence of moisture are insoluble in the carbon tetrachloride. Suitable temperatures and pressures are employed, the temperature being lower than the boiling point of carbon tetrachloride at the pressure used, 40-50 DEG  C. being mentioned. The chlorine may be produced from liquid chlorine and may be previously dissolved in the solvent, or the solvent may be first introduced into the de-tinning chamber and the chlorine then admitted.  The solution is used repeatedly with further additions of chlorine and is then withdrawn, allowed to settle and distilled to separate the carbon tetrachloride from the stannic chloride; or the solution may be distilled over a base such as lime or soda, or may be agitated with and distilled over an alkaline solution when the tin will be obtained as oxide or hydrate; or the solution may be agitated with water, the aqueous solution being decanted from the carbon tetrachloride.  When the process is applied to tin ores, the ore is completely reduced, preferably by hydrogen, and when much iron is present which might form iron-tin alloys, it is preferable to first convert it by a known process into a magnetic oxide and then separate it magnetically before the reduction of the tin.  Carbon tetrachloride is also employed for the removal of the tin chloride adhering to the de-tinned scrap.  The Provisional Specification states that other solvents for chlorine and stannic chloride may be employed instead of carbon tetrachloride, such as tetrachlorethane and petrol, and that hydrochloric acid may be used instead of chlorine.

Abstract: 910,829. Spinning. BIGINELLI, O. F. A. Aug. 25, 1960 [Sept. 16, 1959], No. 29438/60. Class 83 (4). A method of shaping a body of revolution by spinning by means of tools, each tool being arranged to carry out one step of the spinning operation is characterized in that the tools act in immediate succession on the workpiece in order to shape the said workpiece in a single operation without having to reheat the workpiece between successive spinning steps. Apparatus for carrying out the method comprises a series of spinning tools A, B, C, D and E guided by a pattern 13, the contour of which the tools follow by means of rollers A 1 , B 1 , C 1 , D 1  and E 1  respectively, Fig. 1. The tools are each held against the workpiece and pattern 13 by individual hydraulic cylinders. Movement of the tools in the direction of arrow H is limited by an adjustable plate 16 which cooperates with a dog 17 on the tool 14, Fig. 3. The tool assembly is mounted on a reciprocable carriage 3, Fig. 2, which is displaced in the direction G whilst the workpiece is rotated by a motor (not shown). At the end of the forming step the carriage 3 actuates a valve 8 which operates a tool 12 for controlling the final or neck length of the workpiece. As the tool 12 is withdrawn from its working position, a piston 1 advances and ejects the shaped workpiece from the mandrel 4 and then a cam 10 acting on a distributer 5 reverses the travel of the piston 1 and initiates the return movement of the carriage to its starting position. As the piston 1 is withdrawn, the tool 12 moves into its working position. When the carriage is at the end of its return travel it controls the mechanical device of a cam 9 which reverses the travel of the machine. The piston 1 travels forwardly to engage a workpiece and introduce it into the mandrel 4 and a piston 2 entrains the carriage for the working stroke.
