Abstract: 862,074. Drying air. JOHNSON & CO. PTY. Ltd., B. C. Nov. 17, 1958 [Nov. 19, 1957], No. 36933/58. Class 34(1) Air from a motor driven compressor 7, Fig. 1, is dried in one of a pair of absorbent beds 13, each having an electric heater 24 incorporated therein, whilst the other is subjected to a stream of reactivating air the necessary changeover valves 12, 14, 23, 22, being sumultaneously actuated by common control means. The compressed air after passing through a cooler 8, a receiver 9 and an oil filter 10, passes to the threeway valve 12 for admittance to either of the beds from whence it flows through a three-way valve 14, a reducing valve 15, inspection window chamber 16, non-return valve 17 and a gate valve 20 for eventual utilization. Reactivating air is taken from the filter 10 and passed through a metering valve 21 and stop valve 36 to a three way valve 22 from whence it flows to the bed 13 not being used as a drier. The hot moisture laden air is exhausted from this bed through a three-way valve 23. The valves 12, 14, Figs. 5, 6, and 22, 23 are on common rocking shafts 25, 26, which are concertedly operated through a link mechanism 27, 29, 30, by a pneumatically actuated ram device 28 the air supply pipes to the opposite ends of which are joined in a changeover valve arrangement 31 connected to the air receiver 9 through the filter 10. Fig. 2 (not shown) illustrates the control circuit of an automatically operated electrical control system for the air compressor and drying plant. The system may be such that the beds are changed over every six hours and during its reactivation phase a bed is heated for four hours followed by two hours of cooling. In an installation where the compressor is driven by an LC. engine the electrical heaters 24 may be replaced by means utilizing the engine's hot exhaust.

Title: Improvements in methods and devices for disinfecting or sterilising closet seats
IPC: A47K13/30
Filed: 1929-12-03
Abstract: 348,127. Sterilizing &c. closet seats. GRAFANI, L. B., 508, West 114th Street, and PETERSON, R. E., 19, West 69th Street, both in New York, U.S.A. Dec. 3, 1929, No. 37054. [Class 26.] A closet seat is sterilized in a chamber to which sterilizing fluid is admitted, the fluid being subsequently driven out by dry gaseous fluid, the sterilizing fluid consisting of steam containing if desired chemical disinfecting substances. At the commencement of the cycle of operations, a sterilized seat is in position in the chamber; the insertion of a coin closes the circuit of a motor whereby the chamber is opened, and the seat lowered, the motor being then stopped. After use, manual operation of the seat restarts the motor, so that the seat is returned to the chamber, the chamber closed, and the sterilizing process performed. The inserted coin falls into a pocket 218, Fig. 21, and serves as a connection for operating a dog 229 in such a direction as to tilt a mercury switch 222 into its closed position, and to operate stop mechanism 240 for preventing the insertion of another coin. The closing of the switch 222 starts an electric motor 250', Fig. 20, which drives a fan 22, Fig. 2, a shaft 125, and through mutilated gear wheels 127, 129, Fig. 3, a shaft 128. A cam groove on the gear wheel 127 oscillates a block 166, Fig. 6, to withdraw locking arms 165 from engagement with catches 161 on the doors 67 of the sterilizing chamber, and cams on the shaft 128 operate through rods 78 to open the doors, and through a rod 65 to lower the seat. A roller 260 moves into a notch 307 in a cam on the shaft 125 and operates a switch 255, said switch having a finger 305 which simultaneously opens a switch 253, so that the motor is stopped. Manual lifting of the seat after use restarts the motor, whereby the seat is returned to the chamber, and the doors 67 are closed and fastened. After this a cam 178 opens a water valve 91, and a cam 196 closes the circuit through a heater, and steam passes into the chamber through pipes 109, 110, 111, Fig. 5. Finally, an air inlet valve and an air and steam exhaust valve are opened, and through cam action the switches 255, 222 are closed and opened respectively.

Title: Vehicle weight responsive means
IPC: B61L25/08
Filed: 1956-12-06
Abstract: 820,969. Electrical weighing apparatus. WESTINGHOUSE AIR BRAKE CO. Dec. 6, 1956 [Dec. 9, 1955], No. 37331/56. Class 40 (1). In apparatus for measuring the weight per wheel of a railway vehicle, a plurality of carbon resistors, located within a slot in a rail so as to be responsive to deflection of the upper part of the rail into the slot under the weight of a load, are connected in a Wheatstone bridge arrangement, the unbalance current of which is fed to relays differentially biased to operate at discrete load values. As shown, Fig. 1, in a slot 5 in a rail 1 is located a device 9 comprising a base 10 which is bolted to the rail, four rectangular compartments 14, Fig. 3 (two only shown), defined by insulating walls 13, and a pile of carbon discs 15 in each compartment. Deflection of the top of the rail 1 by a wheel 5a depresses, down to a limit imposed by stops 6, a rail contactor 27 to compress, via a member 20, two of the carbon piles, which are connected to form opposite arms of a Wheatstone bridge energized by a battery (not shown), the other two carbon piles comprising the remaining arms of the bridge and providing temperature compensation. The bridge output is fed to the parallel-connected first coils of three two-coil relays (not shown), a second coil on each of which is supplied from a D.C. source with a biasing current the value of which is adjusted by a variable resistor in each second coil circuit to secure that the relays operate separately at predetermined discrete values of unbalance current. In a modification (Fig. 5) two mutually insulated carbon piles are coaxially located in each of two compartments so that depression of a rail contactor 61 mounted on a lever 57 pivotally supported on a bridge member 55, against the action of a coil spring 66, compresses the two piles CP1, CP4, which form two opposite arms of the bridge and reduces the pressure on the piles CP2, CP3, which complete the bridge. The three relays in the output circuit (not shown) comprise two-coil polarized stick relays, the biasing coil of each of which is connected between the mid-point of a D.C. source and the adjustable contact of one of three potentiometers connected across the source, to supply a biasing current to aid or oppose the bridge output current in the second coil and thus to select the relay operation point in each direction.

Patent GB-856232-A (GB)
Title: Improved fastener driving tool
IPC: B25C1/18
Filed: 1958-11-24
Abstract: 856,232. Cartridge-actuated fastener-driving tools. TERMET, P. Nov. 24, 1958 [Nov. 29, 1957], No. 37704/58. Class 119. Relates to a fastener-driving tool of the kind in which the explosion gases move a piston unit which drives the fastener into the workpiece. According to the invention the piston unit 5 Fig. 1 moves in a cylinder 4 held by threading 6 in a sleeve 7 screwed to a separate breech part 1 incorporating the cartridge chamber 3 which is normally closed at its forward end by a rod 47 integral with the piston 5 and passing through a bore in the otherwise closed rear end of the cylinder 4. The closed end of the cylinder 4 has a tapered surface 52 so as to form with a correspondingly tapered recess in the forward portion of the breech part 1, an annular orifice and space which can be varied in width by adjustment of the cylinder 4 in the threading 6 of the sleeve 7. The arrangement is such that on firing, the initial movement of the piston 5 and rod 47 uncovers the annular orifice and permits part of the explosion gases to pass through the annular space, between the cylinder 4 and sleeve 7 and through baffles 53 to atmosphere. The fire-power of a standard cartridge can thus be varied by adjustment of the width of the annular orifice. In a modification, the rod 47 is provided with a projection 48 in Fig. 4 which projects more or less into the cartridge chamber according to the adjustment of the cylinder 4 and provides a further adjustment of the fire-power by variation of the size of the cartridge chamber. A tube 14 Fig. 1 acts as a guide for the fastener 59 and is extended inwardly by a cage 15 containing magnets 17 for holding the fastener in place. The tube 14 comprises also hollow screws 18 containing magnets 19 for holding to the muzzle an attachment member 60 Fig. 6 (not shown) which is to be fixed to the workpiece by the fastener. The breech part 1 is provided with a pair of holes 41 in which are mounted spring-urged cartridge ejector pins 42. A tubular rubber element 56 is used as a brake for the piston unit and is driven forward to engage a washer 57, e.g. of polyvinylchloride.

Abstract: 872,528. Conveyer systems; winch end stop devices. STAHL, A., STAHL, O., STAHL, W., STAHL, B., and STAHL, O., [trading as STAHL MASCHINENFABRIK, R.]. Dec. 4, 1957 [Dec. 5, 1956], No. 37768/57. Classes 78 (5) and 104 (2). In a conveyer system in which trolleys run on rails having at least one vertically-movable section connected by a rope or cable to an electrically-operated hoist, fixed stops and limit switches and overload-preventing means, each of the fixed stops locates the movable section in a predetermined upper position, the limit switches switch-off the electric hoist when the section is in its desired upper or lower position and the overload-preventing means is either in the form of a slipping clutch between the rop or cable and the hoist or a spring interposed between the section and the hoist. In the arrangement shown in Figs. 1, a rail portion 2 is moved vertical by a winch 3 to a position determined by stops 4 in which position the rail portion 2 is aligned with the track 1. When in the aligned position a slipping clutch, Fig. 2 (not shown), inserted between the winch driving motor and winch drive, prevents overloading of the winch 3. In an alternative arrangement shown in Fig. 3, over-travel of the winch 3 is taken up by a spring 9 and a limit switch 8 breaks the electric circuit to the winch driving motor.

Abstract: 1514410 Waveguide mode transformers COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL SA 13 Sept 1976 [24 Sept 1975] 37868/76 Heading H1W A mode transducer for transformations between the rectangular TE 01  mode and the circular-electric TE 01  mode comprises a rectangular waveguide 8 and a semicircular waveguide 9 coupled by a row of orifices 7 arranged in a wall common to the planar side of the semicircular guide and to a narrow side of the rectangular guide, the width of the orifices being substantially the same as the width of this narrow side. The transducer may be formed from three machined conductive blocks 1, 3, 5. The dimensions of the guides satisfy the condition:  r + a + e < 600/F max  where r is the radius of the semicircular guide, a is the width of the broad side of the rectangular guide, e is the thickness of the common wall and F max  is the upper limit of the working band in GHz. In Fig. 3, the semicircular guide bears the reference 13 and the transducer occupies the right-hand portion of the construction. The left-hand portion includes an additional semicircular guide 15 containing a sectorial element 16 having an included angle which varies linearly from 180 degrees at the right-hand end of guide 15 (where it completely fills the guide) to 0 degrees at the left-hand end (where it forms a radial septum). The left-hand portion of the construction thus forms a semicircular-tocircular wave-guide transducer.
