Title: Improvements in or relating to the impregnation of absorbent materials with bituminous compositions
IPC: D21H17/61
Filed: 1945-01-30
Abstract: In the weather- and water-proofing of absorbent materials by impregnating them with a hot liquid bituminous composition, foaming of the composition is inhibited by adding up to 5 per cent of an organic silicone, e.g. dimethyl silicone.  The silicone may be dissolved in naphtha or kerosene.ALSO:A small proportion of an organic silicone is added to a liquid bituminous composition which is used at elevated temperature, e.g. 250 DEG -450 DEG  F. to impregnate absorbent material (see Group VIII), to make it waterproof and weather-resistant.  The process is particularly useful for manufacture of roofing felt.  A liquid alkyl silicone is preferred. The product specifically referred to is Dow-Corning Fluid No. 200-consisting primarily of dimethyl silicone polymers.  The silicone may be added as a solution in naphtha, kerosene or other hydrocarbon. Preferred bitumens are blown petroleum ashphalts or blends of a steam reduced residual or ashphalter stock with a blown ashphalt. Absorbent materials mentioned on wood, paper, pulp, fibreboard, asbestos, felted or woven fabric.  The amount of silicone may range from as little as 1 part per million up to 5.0 per cent based on the weight of the composition.

Abstract: 1,113,763. Angular bending. STAFFORD TOOL & DIE CO. Ltd. 16 Jan., 1967 [18 Jan., 1966], No. 2383/66. Heading B3E. A bending machine having a hammer and an anvil between which strip steel may be placed for bending, and means for moving the hammer towards and away from the anvil is characterized in that an electrically-operable control arrangement is provided for controlling said means to cause the hammer to reciprocate repetitively whereby to cause a series of hammer blows to be effected on said strip in order to provide a bend therein. Strip steel having one or both edges sharpened is bent by repeated blows from a tool 6, carried by a reciprocating hammer 4, co-operating with a tool 5 on an anvil 3, the mean position of the stroke and the length of the stroke of the hammer being so controlled that the bend is formed gradually by a series of blows. The strip may be moved slightly between each hammer blow so that the series of hammer blows required to form one bend do not fall in exactly the same place. The hammer 4 is reciprocated by a double-acting hydraulic ram 7 controlled by switches on a platform 17 co-operating with a projection 16 on the ram 7. The position of the platform 17 is controlled by a pedal 60. In one mode of operation of the machine successive depression and relaxation of the pedal 60 in conjunction with the operation of a switch (33), Fig. 3, not shown, on the platform 17 by the projection 16 causes the hammer to reciprocate. In a second mode of operation of the machine for continuous automatic reciprocation a foot switch (26), Fig. 6, (not shown), is depressed to de-energize switch (33) and activate switches (27), (32) on the platform 17, the length of stroke being adjusted by adjusting the switch (27) and the mean position of reciprocation by moving the platform 17 by the pedal 60.

Title: Vibrator
IPC: B06B1/18
Filed: 1959-01-26
Abstract: 908,171. Consolidating concrete &c. by vibration. MALAN, G. L. Jan. 26, 1959, No. 2803/59. Class 86. [Also in Group XXIV] A vibrator for consolidating plastic masses comprises a cylindrical rotor 31 with radiallyextending reciprocatable vanes 39, 40, 41, the rotor being free to move in a cylindrical housing 24 of equal height but greater diameter. Compressed-air admitted behind the vanes to thrust them successively against the rotor housing, and to the expansible chamber formed between the rotor and housing behind that vane which is for the time being in contact with the housing, causes the rotor to roll in a clockwise direction round the housing while itself rotating counter clockwise. The air is introduced into the apparatus through a hose 11, inlet port 21, duct 28 and port 26, and is exhausted from exhaust grooves 19, 27 and ducts 18, 29 through the annular passage formed by chamber 17 and hose 12. In Fig. 3 air passes from ports 26, 47 through passage 46 to the chamber 44 behind vane 39, and also through groove 54, passage 56 and valve 58 (which is opened by the contact of a cam arm 64 with the housing-see Fig. 2, not shown) to the expansible chamber 68 which is opening in rear of vane 39 between the rotor and the housing. At a later stage, port 47 moves out of communication with port 26, valve 58 closes, and vane 39 ceases to be in contact with the housing; air can then escape from chamber 44 through passage 67, and from chamber 68, past vane 39 to the exhaust groove 19. Port 51 is shown approaching port 26, whereby air will be admitted under vane 41 (as by passage 49 for vane 39) to retract the vane and prevent violent contact with the housing. The passages are so arranged that a small cushion of air is left under the vane at the end of its travel to cushion it and by re-expansion to assist in reciprocating it. The forward outer edge of the vane may be chamfered, see Fig. 4 (not shown). An alternative arrangement of ports and passages is described with reference to Figs. 5-10 (not shown). Specification 908,172 is referred to.

Abstract: 724.405. Push button lifts. EXPRESS LIFT CO., Ltd., and HUNT, S. T. Feb. 2, 1953, No. 2922/53. Class 40 (1) In a control system.for a lift including destination switches in the lift car for selecting the floor to which the passenger in the car wishes to proceed, and switches on each floor for calling the car to that floor; over-riding means is provided for causing the car to proceed to a predetermined floor disregarding any demand already made and for rendering the calling switches on each floor ineffective to control the car, but after the car has returned to the predetermined floor, allowing a desired destination to be selected by operation of a destination switch in the car. In the arrangement shown, the invention is applied to a control system comprising car push buttons 21-28 and landing push buttons 31-38, which operate relays 101-108 connected with a circuit (not shown) for driving the car to the selected floor. When it is desired to commandeer the car, a switch 13 is closed so energizing relay FC which renders the relays 102-108 inoperative by open circuiting their locking circuits at contacts FC1 and isolating the car and landing push buttons at contacts FC2, FC3. Simultaneously, relay 101 is energized through contacts FD1 and the car is driven to the ground floor where it automatically closes contacts LL so energizing relay FD which locks over contacts FD2, de-energizes relay 101 at contacts FD1 and, by closing contacts FD3, FD4, renders the car controllable from the car push buttons whilst the landing push buttons remain inoperative. Opening of switch 13 de-energizes relays FC. FD and restores the system to its original state. The invention is stated to be also applicable to multicar systems, in which all or one of the cars can be commandeered during an emergency.

The sheets of each pair are mounted one behind the other and insulated from one another. Each conductive sheet 7, 8, 9, 10, 11, 12 is connected to a terminal included in an electrical circuit whereby the two conductive sheets of each target element are temporarily electrically bridged when a metal projectile penetrates the two sheets and the respective circuit is closed. At least two of the target elements are situated in planes inclined with respect to one another, whereby the relatively inclined target elements when traversed by a projectile produce pulses in timed sequence, the time interval between the pulses being dependent on the position of the hit point of the projectile on the target. In the construction shown a marked sheet of paper 2 forming the visible target and the central target element 5 are parallel to each other, the elements 4 and 6 being inclined, each in a different direction, to the central target element 5 (Fig. 3, not shown). In this configuration the pulses denote the X- and Y-co-ordinates of the "hit" which coordinates may be displayed on the shooting stand on an indicating apparatus (Fig. 6, not shown). The first two target elements may be plane and parallel with the third element in the form of a cone (Fig. 5, not shown). A fourth element parallel to and adjacent the second element may be provided such that the speed of the projectile may be ascertained. The forward sheet of the first element may be split up into a plurality of zones, insulated from one another such that, using the conical third element the co-ordinates of the hit may be determined (Fig. 9, not shown). The sheets may be of metal foil or a conductive rubber and the insulation of sponge rubber or foamed plastics material. The second sheet of each element may be provided with a protective backing 16, 17, 18.
