Title: Improvements in or relating to metal-to-wood fastenings
IPC: E01B9/16
Filed: 1953-06-22
Abstract: 739,013. Screw-sockets; rail-spikes; woodscrews. SNYDER, J. R. June 22, 1953, No. 17208/53. Classes 89(1) and 89(2). [Also in Groups VIII and XXX] A metal-to-wood fastening comprises a metal fastener e.g. a spike or screw, engaging a bore in the wood member, a capsule of treating material being placed in the bore whereby the driving-in of the fastener ruptures the capsule and diffuses the material into the wood about the bore, so that when set, it hardens and preserves the wood and increases the strength of the connection. The material comprises a thermo-setting resin, e.g. phenol, urea, melamine or resorcinal formaldehyde and a hardener e.g. formaldehyde, and may additionally include a plasticizing agent, e.g. a vinyl resin. Suitable proportions by weight are 93 to 30 per cent of aldehyde resin ; 2 to 20 per cent of vinyl resin and 5 to 50 per cent of hardener. As shown, the fastener comprises a spike 14 or screw 13 or 16, Fig. 1, securing a rail 12, sole plate 11 and tie 15, respectively, to a wooden sleeper 10. The treating material is packed in a capsule 40, Fig. 3, the hardener 43 being separated from the resin 41 by an inner partition 42. In another form the resin is contained in a capsule 45, Fig. 4, and the hardener in an end compartment 47. The capsules may be of moulded plastic material which resists chemical action of the material contained thereby, and may fit the preformed bores 19, 20, 31 in the sleeper. The resin and hardener are mixed in the bore after rupture of the capsule by the screw or spike. The spike is of square cross-section with a chisel point and the screws have tapered portions 27, 37 which cause pressurization of the treating material as they are driven in.

Abstract: 688,055. Testing resistances. FIRESTONE TIRE & RUBBER CO. July 11, 1950 [Nov. 12, 1949], No. 17331/50. Class 37. If the tyre 10 under test for antistatic condition has a resistance equal to or below that of a standard tyre a resistance-capacity phase shifting network comprising the tyre 10 and a fixed capacitor 61 operates to produce a firing potential on the grid of a thyratron 18 and thus actuation of an indicator lamp 48. To set up the apparatus for test use the standard tyre of known resistance is inserted at 10 and the grid potentiometer resistance 50 thereupon adjusted to the point at which the thyratron fires, i.e. just above cut-off. The fixed resistance 63 in the phase-shifting network keeps the current low across the electrodes 11, 12 in the event of an operator inadvertently touching the electrodes. A delay switch 27 withholds the anode potential until the cathode has reached operating temperature.

Title: Improvements relating to pneumatic motors
Inventor: BAYES CHARLES ARTHUR
IPC: B60S1/10
Filed: 1953-06-23
Abstract: 748,180. Compressed-air engines; vacuum engines; engine valve gear; semi-rotary engines. TRICO-FOLBERTH, Ltd. June 25, 1954 [June 23, 1953], No. 17397/53. Classes 110(2), 122(2) and 122(3). A pneumatic motor which may be used for driving a windscreen wiper, comprises a vane or piston 2 oscillated or reciprocated in a cylinder 1 by pressure or suction applied alternately to opposite sides of. the piston under the control of reversing valves 110, 113, 114 operated by movement of the piston, the valves and operating mechanism 127, 129, 132, 133 therefore being disposed within the cylinder 1. The sides of the piston are alternately connected to atmosphere and to a source of vacuum through passages 119, 123 respectively, connected by flexible pipes 125, 126 to a valve 139 which may be operated manually by a cable to effect parking of the piston at the end of the cylinder or to divert the source of vacuum to a windscreen washer. The mechanism for reversing the valves comprises the rod 127 slidably-mounted in the piston and connected to the pin 133 between the valve stems 134, 135 by toggle links 129, 132, Fig. 4, pivoted on a bracket 131 on the piston, and a spring 136. Near the end of the piston stroke, the rod 127 contacts one of two adjustable stops 128 and is displaced in relation to the piston, inverting the V- formation of the toggle links 129, 132 and reversing the valves 110, 113, 114 which may comprise rings of rubber supported on the valve stems. The source of vacuum is connected to the valve 139, Fig. 6, through a nozzle 145, leading to a port 141 in the valve housing which opens into a passage 160 in the valve. When a further port 142 in the valve housing is uncovered by the valve, the source of vacuum is coupled to the piston through the pipe 126, a port 143 in the valve housing connecting the flexible pipe 125 from the piston to atmosphere. The piston is parked against an adjustable stop 148, which closes a chamber in the piston formed by a projection 147, when the valve covers the ports 142, 143 and connects the source of vacuum to the chamber in the piston through a port 144 and a flexible pipe 146, the covering of the port 143 effects slowing down of the piston as it approaches the stop 148. A further port 151 may be uncovered by the valve to connect the source of vacuum to a nozzle 161 supplying a windscreen washer.

Preferably, the printing stage involves the use of a plurality of printing cylinders co-operating with an offset surface, Fig. 7 (not shown). In a modification, the continuous tone transparencies can be produced by lay-up of colour areas on acetate materials.

Title: Laboratory filtration rate apparatus and methods
IPC: B01D35/18
Filed: 1960-05-18
Abstract: Filtration apparatus comprises a filtration member having a screw-threaded outlet stem depending from it, the stem being engaged in a threaded aperture in the base of a thermostatically-controlled heating bath which surrounds at least part of the filtration member. A Buchner flask or the like having a pressure-tight stopper may engage the lower end of the stem in a pressure tight manner. Preferably the filtration member consists of a funnel with a perforate plate on which a filter paper is placed.  Rates of filtration of oil through different, or differently-prepared, bleaching earths may be compared by mixing oil and earth, heating the mixture, pouring it into the filter member and timing the filtration in each case.  Degrees of retention of oil by earth may also be compared.  Bleaching efficiencies may be compared by comparing colours of filtrates. Several filter members may be associated with one heating bath. The bleaching earth cake may be removed bodily by placing on it a filter paper, applying to it the perforated end of a hollow drum, evacuating the drum, and removing the drum with the adhering cake.
