Title: Improvements in and applicable to the impregnation of permeable substances with rubber latex
Filed: 1928-03-29
Abstract: 316,335. Head, P. H. March 29,1928. Waterproofing; proofing processes and compositions.-A process for impregnating permeable material with rubber latex consists in subjecting the material to vacuum in an impregnating chamber, introducing into the chamber latex which has been stabilized so as to prevent spontaneous coagulation at normal temperatures and to facilitate penetration into the material, and then completing the impregnation by pressure. Preferably stabilized latex known by the registered Trade Mark " Xetal " is used. The material is placed in a chamber 1, and a pump 6 operated to create a vacuum in the chamber. The, latex is then admitted from a vessel 2 communicating with the chamber 1. Air is then pumped into the chamber 1 up to a pressure of about 60 lbs. per square inch. The latex is stabilized to prevent spontaneous coagulation at temperatures of 60‹ to 65‹ F., and is also stabilized as to its rubber content and viscosity. The process is particularly applicable to the manufacture of textile driving and other belts and ropes. The material may be removed from the chamber while still wet and dried under tension in order to prevent stretching when in use. The tension may be applied by means of a winch, or by passing the material through sets of calender rollers running at different speeds. The impregnation precess may be modified' by withdrawing the latex from the chamber 1 after the impregnation, and heating the chamber so as to coagulate the latex in the material. A vacuum may then be created in the chamber to extract the remaining moisture from the material. Belting impregnated by this process may be woven in a single layer, or multilayer belting may be used, the layers being partially attached before being impregnated. The Provisional Specification states that the impregnated material may be boiled for from five to ten minutes, preferably after the latex has solidified. either in water to which a small quantity of sodium or other chloride has been added, or in sea water, or it may be treated with steam.

Filed: 1948-04-05
Abstract: 652,113. Selective punching machines. CREED & CO., Ltd. April 5, 1948, No. 462. [Class 31 (ii)] [Also in Group XL (b)] Keyboard apparatus for perforating a tape in accordance with code signals comprises a first set of longitudinally movable combination bars in operative relation with character key levers, a second set of longitudinally movable members normally out of operative relation with the key levers, and a shift key lever which, on actuation, changes the operative relation of the sets of combination bars and, on release, restores the operative relation between the key levers and the first set of combination bars. As shown in Fig. 1, one set of code combination bars, typified by the bar 1, is held in operative position relative to the key levers 2 by projections 10 formed on the underside of the code bars and resting on rollers 6 rotatable on pins 8 carried by a bar 9, the width of the projections 10 being sufficient to allow the requisite longitudinal movement of the bars 1. When the second set of bars, represented by the bar 3, Fig. 2, is to be moved to the operative position, the clockwise rotation of a bell-crank 14 by the shift key-lever 15 moves the bar 9 to the left so that the lower surfaces of the projections 12 are supported on the rollers 6. Pivoted levers 17, 18 utilized to operate members for controlling the punching operation engage bevelled notches 20 in the bars 1, 3 and the extent of movement of the sets of bars is limited by stops 21 which provide abutments for effecting the raising of the bars 1, 3 when the rollers 6 engage the sloping surfaces 11, 13 of the projections 10, 12. When the lever 15 is released, the bar 9 returns to the right, under the action of a spring (not shown). The sets of bars 1, 3 are supported by slotted guide plates 5. A universal bar, indicated in Fig. 3 (not shown), is provided with projections sufficiently wide to be supported by the rollers 6 during its movement in both positions of the bar 9. Specification 422,134 is referred to.

Abstract: 715,689. Drying clothes. PUGH, R. G. April 25, 1951 [Dec. 9, 1950], No. 9756/51. Class 34(2) Clothes drying apparatus having a closed air circulating path including a container has an aspirator jet propelling cool water longitudinally of the air path to draw air through the container and means to collect water suspended in the air after passing the jet. The clothes C are contained in a horizontally tumbling drum 20 in a casing K and drying air flows longitudinally of the drum then upwards through the open end of the drum to a duct 22 through which it is drawn by the aspirator jet 24 located at the junction of ducts 22 and 26, and cooled by the jet so that evaporated moisture condenses to join droplets of water travelling through duct 26 whence the air enters a separator 28 to produce at A3 cool air free from condensed moisture. This air stream enters an air-header 74 having fan-shaped openings 74a each covered by an electric heating element 78 through which the air passes into the drum via a screen 72 the lower half of which is covered by a semicircular baffle plate 82. Heavier lint is trapped in a U-shaped channel 94, fine lint collects on the wall of duct 26 where it is removed via access cover 98 and the very fine lint becomes entrained ,in the water droplets and is disposed of with the water from separator 28 via pump 104. The water supply to aspirator jet 24 is controlled by means of a solenoid valve 98a in pipe 96 energized through timer switch 110.

Abstract: 547,641. Hydraulic presses. E. M. B. CO., Ltd., CATLIN, L. A., and COCKERILL, W. H. Aug. 1, 1941, No. 9844. Addition to 532,495 [Group XXII]. [Class 69 (ii)] [Also in Groups XXII and V] In a die-casting machine with hydraulic locking means o, 9, as in the parent Specification, interlocking means are provided to prevent injection of the zinc, aluminium, cellulose acetate, or other molten or plastic material until the die is closed and opening of the die until injection pressure is cut off. The control lever 10, Fig. 4 as limited by a stop 24 and flats 23 on the lever shaft 5, and 20, on a bar 19 connected to the piston rod d, is first moved to position 10a, thus releasing the locking means o, 9, by a linkage 7, and rotating a camshaft to operate inlet and exhaust valves and move the pneumatic piston b and die-head a towards closed position. A catch 15, on a rod 17 connected to the head a engages a catch 12 on the lever 10 to move this to position 10b thus locking the rod d by closing the valves o. The lever 10 is then pulled forward to disengage the catches 12, 15 and moved to position 10a again so that the piston b moves to close the die and bring a recess 21 of the bar 19 adjacent the flat 23 so that, if the lever 10 is pulled forward to clear the stop 24, it can be moved to position 10c thus rotating the cam-shaft still further, thereby operating valves to inject the molten material. To open the die the lever 10 is moved to position 10d thus rotating the cam-shaft in the reverse direction to reverse the injecting valves, open the locking valves o, and operate the valves of the cylinder c to move the head towards the open position 10e and lock the rod until the lever 10 is pulled forward, to disengage the catches 13, 16 and again moved to position 10d. The catches 15, 16 can be made inoperative or be adjusted to ensure that the movement of the head a is interrupted at positions desired for inserting and withdrawing cores.
