Patent GB-612242-A (GB)
Title: Improvements in or relating to electrical welding equipment
IPC: B23K11/26
Filed: 1946-05-21
Abstract: 612,242. Supply systems for resistance welding; condenser arrangements. STANDARD TELEPHONES & CABLES, Ltd., and ASHFORD, J. L. May 21, 1946, No. 15354. [Class 38 (iv)] In a control system for a capacity discharge welder, electromagnetic relays or switches control the charging and discharging of the condenser in such a manner that (1) the condenser is automatically charged between discharges, (2)'successive discharges pass through the primary winding of the welding transformer in opposite directions and (3) the relays or switches do not consume current between welds. As shown in Fig. 1, the system comprises a latch-in relay having operation and release coils DA, DB, respectively, a doublewound relay C and contactors A, B for reversing the connection of the condenser CN to the welding transformer X, Y. With the relays and contactors de-energized, their contacts are in the positions shown, so that the condenser is charged over contacts A1, B1. Closure of the weld-initiating switch FS energizes contactor A and discharges the condenser over contacts A2, A3, whilst disconnecting it from the charging source at A1. Release of FS de-energizes A, disconnecting the transformer and re-establishing the charging circuit, the charging current flowing through DA which picks up, latches in, closes contacts DA2, DA3 and opens contacts DA1. Closure of FS to initiate another weld now energizes contactor B so that the condenser discharges through the transformer in the reverse direction. Relay C is also energized and holds in over contacts C3, DA3, its contacts C1, C2 changing over so that when FS is opened the condenser charging current flows through the coil DB to release the DA contacts. Relay C holds in over contacts DB until the charging current has fallen to a low value, when DB and C will release. Opening of FS has also de-energized contactor B, so that the operating cycle is complete. In a modified arrangement the latch-in relay directly operates the reversing contacts for the transformer, the contactors A, B being replaced by a single relay controlled by the initiating switch and having change-over contacts for connecting the condenser to the charging and discharging circuits.

Title: Method of and machine for sorting and separating mica
IPC: B07B4/02
Filed: 1928-05-25
Abstract: 317,553. Frederick, L. T. May 25, 1928. Pneumatic separating.-Mica flakes are separated according to their thickness by dropping the mixed flakes down a tower 10 and applying suction at an opening 14 so as to remove those of the required thinness and flexibility. The thicker flakes drop into one compartment 28 of a bin 13 and may be subjected to further disintegrating and separating operations and the selected flakes, before collection in the compartment 29, may be subjected to a further grading by suction apparatus. In the apparatus described, the mica blocks, after being soaked in a mixture of soapstone and water and dried, are fed to a reticulated drum 11 which disintegrates the blocks, the flakes falling through the meshes into the tower. The suction device at the foot of the tower comprises two oppositely rotating perforated drums 15 in the interior of which is produced a partial and regulated vacuum The flakes adhering to the drums are carried out of the tower and are stripped by the action of tangential air blasts from elongated nozzles 24 in combination with stationary segmental cut-offs 9. Alternatively a conveyer device as described in Specification 272,429, [Class 70, Indiarubber &c.], may be used. The flakes carried out of the tower are dropped on to a perforated endless carrier 31 under the forward end of which is placed a suction box 34 which acts in combination with the centrifugal action of the carrier 31 to make a further selection of the flakes which fall into the compartments 28, 29 of the bin. An elevator 30 returns the thick flakes to the drum 11 for retreatment. Adjusting devices are provided for the suction, speed of the moving parts, and relative sizes of the compartments 28, 29, so as to regulate the degree of separation.

Title: Apparatus for assisting an operator in performing a skill
IPC: G09B9/00
Filed: 1956-05-18
Abstract: A device for training an operator's reaction in performing an action in response to an indication, has means for making the action more or less difficult according to the skill of the operator.  One form provides a number of buttons to be pressed in accordance with the lighting of a series of lamps.  The particular button to be pressed in response to a given lamp and the order in which the lamps light up are both variable and, in the early part of the training, an indication of the correct button to be pressed may be given by a further set of lamps, but the brilliance with which these are illuminated is decreased as the operator's skill increases.  In addition as skill increases, the time within which a response may be made is decreased.  The means for carrying out these functions comprise essentially a series of capacitors, the charges on which are increased or decreased according to the correctness of the operator's response and, after each series of actions, the charges are used to control the rate of operation &c. of controlling electronic valves. In a second type of apparatus the operator has to press two selected buttons in response to each indication and in a third type he has to follow a target spot of light, on a cathode-ray tube screen, with a second spot.  In this case the movements of the first spot are made more evasive and rapid as the operator's skill increases.

Title: Improvements in or relating to process and apparatus for separating naphthalene from suspensions of naphthalene in water
IPC: C07C7/00
Filed: 1949-06-10
Abstract: <PICT:0686540/IV (b)/1> A process for separating naphthalene suspended in a body of water comprises subjecting the body of water to aeration to produce by flotation a surface scum containing a relatively higher percentage by weight of crude naphthalene to water than the body of water, removing the surface scum from the underlying water and separating crude naphthalene from the water in said scum by centrifugal separation.  The final cooler water from by-product coke oven gas purification may be treated.  Residual oil, if present, is separated also in the last step.  The final cooler water may be re-used after removal of the surface scum.  Carbon monoxide or stack gas may be employed for aeration.  In an example, using the apparatus shown in the drawing, water after cooling coke oven gas in a final cooler 10 passes to one or more aeration flumes 16 supplied with air through pipes 18 and cells 19.  The surface scum formed is removed by a scraper conveyer 22 and the remaining water flows over a float controlled weir 20 to waste or back to the final cooler.  The scum is conveyed to a collection sump 24 and thence by bucket elevator 25 or other device, e.g. a slurry pump, to feed tank 26 optionally fitted with an agitator and to which air and cold water may be fed.  The slurry is drawn off and fed to a centrifugal separator 31.  A centrifuge of the perforated basket type may be loaded and unloaded with liquid or steam rinsing if desired, separated liquids being removed through conduit 21.  Oil may be separated and recovered. Crude naphthalene admitted to the centrifuge may be rinsed with hot water and the load spun to the desired dryness and removed.  Residual water may be removed from the product at a temperature above 100 DEG C. e.g. in tank 35 heated by a steam coil 36.  For crude naphthalenes containing high proportions of tar, pitch and coke breeze a scroll-type centrifuge may be used.  The naphthalene may be aged before centrifuging, e.g. in tanks in series between the aeration flume and tank 26.  Naphthalene is withdrawn by a steam-jacketed pump 37 through a conduit 38 preferably heated electrically or by steam. Specification 510,835, [Group II], is referred to.

Title: Improvements in or relating to machines for casting metals
IPC: B22D17/24
Filed: 1946-05-22
Abstract: 612,846. Casting-machines; moulds; extracting castings. SOC. D'APPLICATIONS MECANIQUES POUR L'AUTOMOBILE, S.A.M.P.A. May 22, 1946, No. 15567. Convention date, Nov. 7, 1945. [Class 83 (i)] In a die-casting machine having a number of cores and die elements, a piston and cylinder device for controlling each of the cores and its corresponding die element comprises a cylinder with two sections of different cross-sectional area, a piston in each section, the larger piston being on the opposite side of the smaller piston from the die and the larger piston having a rod passing through the smaller piston and connected to the core, means for supplying pressure fluid between the pistons and means to limit the relative displacement of the pistons to substantially the length of the core. In the form shown in Fig. 1, the machine comprises a table 1 mounted on axes 2 and tiltable by means of a pressure fluid cylinder 14f, a core 8 withdrawable through an opening in the table by means of a cylinder 14e, a number of mould parts or die elements such as 6 and 7 and lateral cores such as 10, 11 and 12 in the form of spindles passing through parts of the mould, and adapted to be withdrawn by means of pressure fluid cylinders 14d, 14b and 14c respectively. Each of the spindles operating a lateral core contains a piston 13, Fig. 3, whose rod 15 is secured to the core 9 and also carries a block 17 movable within a hollow piston 16, one end of which operates within the cylinder 14 and the other end of which is secured to that part of the mould through which the core passes. As pressure fluid is admitted to the cylinder at 18, the piston 13 moves back, withdrawing the core 9 and when the block 17 engages the end of the piston 16, further movement of piston 13 serves to withdraw the mould part and so release the casting. The admission of pressure fluid to the various cylinders for the withdrawal of the cores and mould parts for bringing the table from an inclined pouring position to the horizontal position as the metal solidifies, is controlled by a single slide valve operated by a rotary cam (not shown). A modified form of machine for casting aluminium pistons has a two-part mould with vibrators adapted to be operated just before the withdrawal begins.
