Title: Improvements in or relating to electric alternating current signalling systems
IPC: H04M1/50
Filed: 1942-07-28
Abstract: 554,806. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. (Western Electric Co., Inc.). July 28, 1942, No. 10527. [Class 40 (iv)] In a subscriber's number sender which employs reeds for generating alternating currents of various frequencies, in order to compensate for the attenuation of the line, the amplitude of the generated currents is made dependent in an inverse manner on the strength of the direct current received from the exchange. As shown, the reeds 2 .. 6, Fig. 6, are located near an element 1 of magnetic material and are surrounded by a field coil 7 which is connected across the line and in which an E.M.F. of appropriate frequency is induced when one of the reeds is set in vibration. If the element 1 is of low hysteresis material such as soft iron, the field coil is wound so that the flux due to the line current aids the steady flux and the working range lies on the descending part of the permeability curve 9, Fig. 5. The element 1 may however be wholly or partly of permanent magnet material with the variable flux either aiding or opposing the steady flux, the rising part of the permeability curve being used in the latter case. The sender comprises ten pushbuttons attached to levers 17 and arranged in two banks. Each lever 17 is formed with two lugs 32, 33 which bear on two of five U-shaped bars 12 .. 16 each of which is provided with a lever 34 for the actuation of the corresponding reed. The reed 2 is normally bent upwardly by a finger 35 and the rotation of the lever 34 first withdraws the finger 35, allowing the reed to engage a pawl 36, and then by means of another finger 37 withdraws the pawl 36 to set the reed vibrating. The return of the lever 34 by spring action restores the reed to its normal position.

Abstract: 1,092,418. Sink-float separation. K. F. TROMP. March 12, 1965, No. 10665/65. Heading B2H. The separation of solids, (e.g. raw coal or ore), having specific gravities by means of a body of suspension of uniform density in a tank 1 is carried out by creating a horizontal flow near the top of the body of suspension by supplying a first quantity of suspension through a nozzle 9 at the front end of the tank, withdrawing this flow together with the floats at the rear end of the tank, creating a downward flow along the front wall of the tank by supplying a second quantity of suspension through a nozzle 10 and withdrawing this flow together with the sinks from the bottom of the tank. The floats are flushed on to a screen 14 and the sinks lifted through a pipe 7 on to a screen 16, the suspensions being drained to a common tank 15 for delivery by a pump 27 back to a tank 20. The tanks 17 and 20 serve as measuring tanks; by keeping the water levels in these tanks the same distance above orifice plates 19, 22 by use of weirs 18, 21, the volume of suspension passsing through the tank from each nozzle to its respective discharge point remains the same and the zone above the lower edge 11a of guide plate 11 is kept free of upward or downward currents. The volume of suspension passing through pipe 7 should be such as to lift the largest piece of sinks and prevent the density in the tank from increasing with depth; if the densities differ at the discharges; adjustment may be made by operating valve 12. The discharge of pipe 7 is controlled by a regulator 25 which may be operated manually or by, for example, an electronic device or float as shown.

Abstract: 613,149. Spray-producers. GENERAL STAMPERS, Ltd., and LEER W. VAN. April 9, 1946, Nos. 10914/46 and 9214/47. [Class 69 (iii)] [Also in Group XXVIII] A sprayer for liquids comprises a tubular sheet metal body 1 divided into two co-axial chambers 4, 5, the former serving as a liquid reservoir and the latter housing a manuallyoperable single-acting reciprocating piston 12. A hole 19 in the upper part of the pump cylinder forms an air outlet into a tapered air discharge conduit 20 running longitudinally along the outside of the reservoir or flush with the surface thereof and formed in part by the wall of the reservoir and in part by a complementary cover. 21 fixed thereto. The end 24 of the conduit remote from the pump cylinder is open and has a tubular bush 25 secured co-axially therein to the rear end of which is fixed a liquid-suction tube 27 extending into the reservoir through a hole 28. Thus, air forced through the conduit 20 by the pump draws liquid up through the tube 27, atomises it and projects it out through the end 24 of the conduit. To support the sprayer in a position where the conduit 20 is uppermost a spring clip 30 is provided at the nozzle end of the body 1 and is formed with two laterally-spaced feet. Fig. 6 shows a modification wherein the front end of the conduit 20 has a small central hole 41 aligned with a diametrical hole 42 in the end of the tube 27 which terminates vertically in the conduit. Seated in the air outlet hole from the pump cylinder is a ball 44 which may be spring- loaded and forms a non-return valve. A hole 45 is provided in the wall of the reservoir forming the lower wall of the conduit so that on the forward stroke of the piston, air both atomises the liquid drawn up through the tube 27 and enters the reservoir and builds up a pressure therein to provide sufficient air to maintain the operation of the sprayer during the return stroke of the piston.

Abstract: 115,440. Berry, B. F. Aug. 2, 1916. Guillotine type. - In apparatus actuated by fluid pressure and intended for the cutting of a pile of bonds, banknotes, tags, labels, &c., a link-suspended knife is alternately moved towards and away from the table by effecting a connexion first with a highpressure fluid tank and then with a low-pressure tank. During the cutting-operation, the work is held by a clamp which is also actuated from the fluid tanks, the knife and clamp being actuated by separate piston mechanisms. The knife 21 is detachably fixed to a bar 41 carried by a beam 43 which is slidably mounted in the standards 46, 46<1> of the machine and suspended by links 48, 50. The link 50 is connected to a piston-rod 51 working in a clyinder 52 which is pivoted at 60 to the bed-plate 59<1>, a port 55 being connected to the high-pressure tank 31 by a flexible tube 56 and a pipe 59 with an intermediate valve 57 and hand-lever 58. A port 53 at the lower end of the cylinder is connected by a flexible tube 54 to the low-pressure tank 37, and the valve 57 is fitted with an exhaust port 61. A clamping-member 20 with grill 23 has end pins 25 connected by rods 30 to an arm 29 which is actuated from a cylinder 27 fitted with ports 32, 38 for connexion with the high and low pressure tanks respectively, a valve 34 with handlever 35 and exhaust port 40 being provided in the pipe 36, 33 connecting the cylinder with the high-pressure tank. The levers 35, 58 may be connected by a link 62 with a pin-and-slot attachment 64, 63 to the lever 58. The knife operates with a swinging cut, and in order that it may be adjusted so that its edge will just come down into contact with the upper face of the table, the pins 65 connecting the links 48, 50 with the knife beam 43 are provided with eccentric disks journaled in the beam, and the pins are secured to worm-wheels actuated by hand-adjusted worms 68. For automatically starting the knife beam on its upward stroke, the link 50 is fitted with an adjustable screw 76, Fig. 14, which is adapted to engage the valve-pin 74 of a valve 69 connected by a pipe 75 with the pipe 33 and by a pipe 77 with an extra cylinder 78. The opening of the valve in this way allows fluid to pass to the cylinder 78 so that, by means of the piston-rod 79 and lever 80, the valves 34, 57 are actuated. A small vent 81 allows compressed fluid to escape from the cylinder 78 when the hand-levers are reversed by hand to effect the down stroke of the knife. The pressure in the high-pressure tank is maintained by a compressor, and for the purpose of maintaining a constant low pressure in the tank 37 it is connected to the tank 31 by a pipe 82 fitted with an equalizing-valve 83.

Title: Improvements in or relating to pump and motor assemblies
IPC: F04D29/60
Filed: 1944-06-09
Abstract: 588,102. Centrifugal pumps. THOMPSON PRODUCTS, Inc. June 9, 1944, No. 11086. Convention date, June 12, 1943. [Class 110 (i)] [Also in Group XXXV] Pumped fluid passes through the hollow shaft of the impeller and a bearing carrying the shaft, receives fluid therefrom. The invention is described as applied to a motor-driven fuel pump which is submerged in a fuel tank 10. Fuel flows through a screen 13 into the top of a guide cone 27 and thence to the eye of the main impeller 56. The latter has vane portions 58a which agitate the fuel to eject bubbles of gas and vapour which escape along the outside of the guide cone 27 and pass to the atmosphere through a vent in the top of the fuel tank. The bubble-freed fuel is pumped into a well 126, most of it being discharged into the fuel line through a fitting 25. The remainder enters the hollow driving shaft 36 and a portion bleeds out through ports 55 to lubricate the bottom bearing 53 ; the residue passes upward through the shaft to cool the rotor 35 of the driving motor and bleeds out through ports 44 to lubricate the top bearing 37. From the latter the fuel drains out on to a rotating spinner plate 45 which discharges it through passages 34 to cool the stator 33. The fuel finally drains to the eye of an impeller 50 which discharges it through a passage 49 into the interior of the tank. Back flow is prevented by a flap valve 150. The fitting 25, to which the fuel line is connected, is attached to a chamber 23 by a bolt 26 passing through an end cap 24. The positions of fitting 25 and cap 24 may be interchanged.

Abstract: 664,555. Thermal switches; snap-action switches. PARNALL (YATE), Ltd. March 24, 1950. [April 26, 1949]. No. 11106/49 Class 38 (v). A regulator for controlling the heating elements of an oven so that the grilling element can also be used as a booster element to the normal baking element for quick-heat purposes, comprises two snap-action switches 3, 4, of which the former moves over a dead-centre position, and the latter does not, when opened by a thermal element, such as a bellows 35. The switches comprise movable contacts mounted on trifurcated cantilever spring blades 5, 6, their degrees of opening from fixed contacts being controlled by stops 12, 13. The undersides of the blades are engaged by spring-pressed pins 17, 18 carried by a beam 14 having forked ends engaging guides 15, 16. The beam 14 carries a tube 24 surrounded by a spring 27 and threadedly receiving a rod 29 engaging at one end a bimetal compensator 33 resting on the bellows 35, and at the other end having a pin 30 movable in an adjusting spindle 32. Rotation of this spindle to the grilling position causes a projection on a cam 38 secured thereto to engage and depress a spring 43 which moves the spring 5 overcentre to the "on" position, thereby energising the grilling element for quick heating. The spindle 32 is then rotated to a position corresponding to the temperature to be maintained in the oven, thus causing downward movement of the beam 14 and closure of switch 4 to energise the baking element also. At the desired temperature, the bellows 35 contracts and lifts rod 29 and beam 14 to open both switches 3, 4. When the oven starts to cool, the switch 4 recloses to maintain the required temperature, the switch 3 remaining open. If the spindle is kept at the grilling position, only the grilling element is energised since although switch 3 is also closed, the circuit of the baking element is opened at a switch 41, 42, by a part 39 of the cain 38. The griller is switched off by rotation of the spindle back to the "off" position, thereby raising the beam 14 to open switches 3, 4 and rotating cam 38 to reclose switch 41, 42.
