Title: Overload electric switches
IPC: H01H71/68
Filed: 1920-07-08
Abstract: 147,592. Krupp Akt.-Ges., F. May 15, 1919, [Convention date]. Protective arrangements; electro - magnetic switches.-An overload electro-magnetic switch is brought into the " off " position, against the action of a spring, by a tension coil normally connected up in series with a resistance so that the coil, although sufficiently energized to maintain the switch in the open position, is only active to produce the opening movement when the series resistance has been short-circuited by a separate overload relay energized by a current coil. In the arrangement shown in Fig. 1 for the overload protection of a direct-current motor B, the automatic switch D is controlled by the coil d<3> in series with the resistance F. The relay E carries the motor current and on overload bridges the contacts e<2>, e<3> which short-circuits the resistance F whereupon the motor circuit is broken at the contacts d<1>, d<2>. After a short delay imposed by the short-circuited winding e<5> on the relay core, the resistance is again inserted and the automatic switch retained in the " off " position by the reduced current. To re-establish the motor circuit, the hand switch C is opened whereupon the coil d<3> is de-energized and the switch is drawn to the closed position by the spring d<4>. The core of the switch may carry an additional bridging contact in the short-circuit for the resistance F and in series with the contacts e<2>, e<3>.

Abstract: 1,009,558. Latch fastenings. BLOXWICH LOCK & STAMPING CO. Ltd. Aug. 17, 1964 [May 17, 1963], No. 19645/63. Heading E2A. A lock for a vehicle bonnet or boot lid comprises a latch member 13 controlled by a key operated locking mechanism which permits the bonnet or lid to be opened without access to the interior of the car but prevents it being opened by an unauthorised person and further comprising a safety catch 27 for preventing the bonnet or boot lid from flying open if the latch member has not been properly engaged. The latch member 13 is retained in the locking position against the action of spring 24 by a pawl 16 having a nose 17 which engages an abutment 18 on the latch member. The pawl is pivoted on a pin 19 and its tail 20 co-operates with a flat 21 on a rotatable follower part 22 coupled to the key-operated lock 9 (not shown). The safety catch 27 is mounted on a pin 37 and is held in the latching position by spring 28. A follower part 26 on a common spigot with the follower part 22 engages a step 30 on the safety catch. When the key is operated the spigot is turned and first releases the pawl 16 from the catch 13, releasing a striker 10. Further rotation of the key, turns the follower 26 which releases the safety catch 27. After the striker is released a further spring turns the spigot to its initial position. As the bonnet is closed the striker rides over the safety catch and downward pressure on the lower edge of the notch 15 rotates the latch member until the nose 17 and abutment 18 are re-engaged. In a modification the key releases a handle which turns the spigot to release the catch members.

Title: Improvements relating to fused fabric assemblies
Inventor: KORNREICH ERNST
IPC: D06M17/00
Filed: 1956-07-02
Abstract: A textile fabric composed partly of cellulose acetate and partly of textile material insoluble in solvents for cellulose acetate is treated with a plasticizer for the cellulose acetate consisting of di-(methoxyethyl)phthalate and toluene sulphonamide in relative proportions by weight within the range 30/70 to 70/30 , so that the amount of plasticiser taken up by the cellulose acetate content of the fabric is 20-30 per cent by weight of the original cellulose acetate content.  One or each face of the fabric may then be made to adhere to another ply of fabric, by application of heat and pressure. The plasticiser may consist of equal weights of di-(methoxyethyl)phthalate and toluene sulphonamide, and the latter may be a eutectic mixture of ortho- and para-toluene sulphonamides. In the preferred method, the fabric is treated with an alcoholic solution of the plasticiser until, after evaporation of the solvent, the calculated increase in weight of the fabric is attained.  One face of the fabric may be rendered non-adhesive (e.g. for use as a backing material) by applying a thin protective layer, which may be a bonded fibre fabric consisting of a carded lap of viscose fibres with the optional addition of a small proportion of cellulose acetate fibres, bonded together with viscose applied from solution.

Abstract: 202,317. Berry, H. R. Aug. 10, 1922, [Convention date]. No Patent granted (Sealing fee not paid). Mineral and tar oils. - In converting liquid hydrocarbons into hydrocarbons of lower boiling point, the liquid is supplied by a pump 12 and pipe 10 to the upper end of a column B, comprising solid or hollow members 8 of metal such as cast iron, fireclay, terra-cotta, carborundum, &c., separated by plates 9 with central apertures, and heated hydrogen, water gas, natural gas, &c. is passed into the base of the column from a compressor 2 through a tubular furnace A and pipe 5. The heated gases pass upwards in contact with the oil, which spreads in film form over the surfaces of the members 8. Vapours pass away through a condensing-pipe 14, which is surrounded by a pipe 19 into which uncondensed gases are allowed to expand through a valve 21 to serve as a cooling-agent. The pressure maintained in the column is such that the lowestboiling fraction of the oil to be transformed vaporizes at its " temperature of instability," i.e. the temperature at which, before decomposition or cracking takes place, the molecules will combine with hydrogen and undergo rearrangement. The temperature in the base of the chamber is such that the highest-boiling fraction of the oil will vaporize under the pressure maintained in the chamber. The temperature at the top of the column is maintained, by regulation of the supply of oil and of the heated gas, at the boiling-point of the desired end product.

Abstract: 1,143,409. Stacking-machines. GENERAL ELECTRIC CO. Ltd. 10 May, 1966 [14 May, 1965], No. 20443/65. Headings B8C and B8H. The automated brick stacking arrangement described in Specification 989,121 is modified in that the stack is built up on a rotatable support, thus eliminating the need to have a rotatable gripper head and to traverse the gripper carriage at right angles to its pick-up-release direction. The stack may be built up on a truck on a railed turntable. In the machine shown, bricks on edge are fed by a conveyer 29 to pivoted supports 45 which, when full, swing upwards from the position of Fig. 6 to that of Fig. 7 to form a double row of bricks. The supports 45 carry linked brick supporting pads 52 slideable along them, the pads including grippers (not detailed) which hold the bricks during the pivoting movement. The pads 52 may move apart to space the bricks prior to their being engaged by grippers 21 of the kind described in Specification 989, 121. These depend from a carriage 2 on rails 3 and can pivot 90 degrees about a horizontal axis if desired. The grippers may be in two groups which separate to form a gap in a row. After each layer is formed, the turntable rotates 90 degrees. The control means (not detailed) may be substantially as described in Specification 989,121. The turntable may be raised and lowered to reduce the vertical travel of the grippers.
