Washers 9 are threaded on a substantially vertical rod 12, Fig. 3, the bottom of the rod being cut away to permit the lower washer to be disposed as shown and the rod being mounted on a horizontal axis 2 for swinging movement. The base 10 is provided with a guide 1Od the applicator being introduced from the right along the said guide 10d at the height such that it moves inward and then downward into the gap of a washer D so as to grip the washer and then pull it rightward. As it performs this movement it engages the rod 12 to move it backwards and then to permit it to move forwards and rightwards so that the bottom washer on the rod moves into the position shown to replace the washer which has been discharged. A second embodiment (Fig. 8).-Washers are mounted on a fixed vertical bar 31 and they are abstracted by an applicator which moves in leftwards between the guides 40f and 40e. The bottom washer which is positioned as shown in dotted lines, is then engaged by a downward movement of the applicator, the applicator plus the washer being withdrawn rightwards. The washer during withdrawal engages the sides of members 40 and 40<SP>1</SP> to cause a pivotal movement about pivots 43, 44 thereof, so that elements 40a and 40b engage the next washer on the stack and move it forwards into position for subsequent withdrawal.

When the printing has been effected the lock 24, 25 is released by a member 26 within the device 1 so that the member 15 is returned to its initial position by the springs 17 and the printed ticket is ejected from the slot 5 into a holder 6 from which it may be manually withdrawn.
Patent GB-722488-A (GB)
Abstract: 722,488. Electric condensers. STANDARD TELEPHONES & CABLES, Ltd. Nov. 14, 1952, No. 28762/52. Class 37. A capacitor electrode is manufactured by applying a coating of insulating material to a conductor, cutting slits in the conductor at intervals along its length, dissolving any exposed portions of conductor, and then cutting the conductor into separate sections by continuing the slits to the opposite edge. After coating the conductor with insulating material, the edges may be trimmed to expose the conductor. After dissolving the exposed conductor portions as shown in Fig. 1c, the conductor, bounded by edges 6, has overhanging portions 7 of the insulating layers. The slits are then continued by cutting along lines 8, so that the conductor is exposed level with the edge of the insulation in these portions. The separate electrodes may be stacked in alternate positions, as shown in Fig. 2, and the edges sprayed with conducting material to connect each series of points 10 and 11, to provide a stacked condenser. Uncoated metal electrodes may also be introduced between the coated electrodes, in the assembly. Before the electrodes are separated by cutting along lines 8, a further coating of insulation may be applied to fill the channelled edges. Fig. 3 shows an alternative construction in which this additional insulation 14 has been added, and a further conducting coating 17 has been added to each element, by vaporization, or by passing between coated rollers. The coatings 17 are connected together and form the other electrode of the condenser. The insulated coating may be cured or polymerized by heat treatment. Specifications 712,650 and 713,605 are referred to.

Title: Process for stabilising nitrocellulose
IPC: C08B5/08
Filed: 1978-06-16
Abstract: The invention relates to a process for stabilising nitrocellulose and particularly, to a process for stabilising pre-deacidified nitrocellulose before pressure boiling. According to the prior art problems exist in achieving preliminary stabilisation of nitrocellulose during its production prior to a pressure boiling step. Satisfactory stabilisation could not be obtained unless severe treatments or extremely long stabilisation times were employed. This invention discloses that preliminary stabilisation can be achieved by intensively washing a nitrocellulose filter cake as it is being centrifuged at 1000 to 1600 rpm using warm water sprayed on in an amount of 1 to 10 times the amount of nitrocellulose. Only very short washing times of 15 to 30 seconds are required.

Title: Applying liquid gaskets to workpieces
IPC: B05C5/02
Filed: 1979-07-18
Abstract: A liquid gasket material such as air-curing silicone rubber is applied to a succession of workpieces from a nozzle guided e.g. by a cam (31) over a required path over the work location, the operation of the nozzle being controlled by workpiece sensing means. For simple closed loop paths, the sensing means can detect the presence of previously applied gasket material, and stop the movement of and flow from the nozzle after only a short overlap. If the direction of travel around the loop is reversed between successive workpieces, the starting and stopping points of the nozzle will not progress around the loop, allowing free access to the work location for placement of workpieces. For complicated paths, the flow of material from the nozzle can be switched on several times in a closed loop path around the workpiece by a sensor sensing the edges of the workpiece. <IMAGE>
