IPC: F16B37/08
Filed: 1923-09-19
Abstract: 226,281. Fyfe, J. S. Sept. 19, 1923. Screwing-dies and die-heads.-A nut or die comprises two body portions 1, 2, apertured in alignment at 3, 4, so that they can slide freely over a rod &c. 5. The portion 1 is shaped to receive a spanner, and carries a pair of threaded blocks 11 pivoted on pins 12 passing through parallel walls 7 of the body portion 1. The portions 1, 2 have a limited relative axial movement and are kept in alignment by pins 6. The lower ends of the blocks 11 are pivotally connected to the part 2 by a U-shaped link 15. On pressing the members 1, 2 together, the blocks 11 are caused to grip the rod 5. An arm 18 pivoted to either portion 1, 2, engages over a pin 19 on the other portion to lock the die or nut in thread-engaging position. In a modification, for heavier work, the U-shaped member 15 is replaced by a straight bar and the blocks 11 are bifurcated. When used for screw-cutting, the threads on the blocks are hardened and channelled longitudinally. To keep the blocks up to their work, a U-shaped arm 26, Fig. 7, provided with a clamping screw 29, may be pivotally fitted to the member 1.

Title: Rheostats
IPC: H01C10/12
Filed: 1923-09-19
Abstract: 226,861. Cole, T. N., Ward, G. L., and Richardson, R. P. Sept. 19, 1923. Contacting-solid resistances; powdered and granular resistances.-A variable resistance consists of a pile of carbon discs 1 alternating with resilient metal discs 2 and contained in an insulating tube 3. Through one end of the tube 3 passes an adjusting-screw 6 bearing on a stout metal disc 4. When the end of the tube is of metal, the screw 6 makes contact with the disc 4 through a hole in an insulating-washer 10, which permits the circuit to be broken when resting against the end of the tube. A screw 5 provided with a lock-nut 7 may be provided at the other end of the tube 3 for varying the range over which the resistance is variable by the adjusting- screw 6, as described in Specification 228,481. A spring-pressed plunger 11 engages a reduced portion of the screw 6 to take up wear and make metallic contact. For resistances of small size the screw 6 may be slightly bent for the same purpose. The metal discs 2 may be of phosphorbronze foil and may be bent in one direction only, or may be dished or have tongues struck up from their plane. They may be replaced by spiral springs which can be compressed into one plane. A threaded stem 8 and nut 9 are provided for attachment to a panel. The screw 5 may be coarser in pitch than the screw 6. Both screws 5, 6 may be located at the same end of the rheostat, the pressure-varying screw 6 screwing through the hange-adjusting screw 5. According to one of the Provisional Specifications the metal washers may serve as tapping points and the carbon discs may be replaced by carbon or other granules.

[Class 38 (iv).] The fuel supply apparatus of a governorcontrolled fuel-injection engine used for driving an electric generating plant is normally held inoperative by a spring, but is released so that fuel may be supplied by the energization of an electric starting device. The fuel is supplied by a fuel pump 10 of known kind arranged so that when a solenoid 15 is energized the fuel-supply apparatus is free to function. The energization of the solenoid may be effected by automatic control. In the example shown a lighting circuit 2 when closed is actuated initially by a battery 5 which closes contactors 10, 6 which energize the solenoid 15 and also place the generator 4 in series with a starting winding 7 across the battery the generator being thus driven as a motor and driving the engine 9. A time lag device 8 short circuits the starting coil and allows the engine to drive the generator. When the load falls off sufficiently to open the load-responsive switch 3, solenoid 15 is de-energized and fuel-supply cut off. Specifications 322,097, [Class 7 (ii), Internalcombustion engines, Arrangement &c. of], 352,524, and 368,346, [Group XXVII], are referred to.

Title: Improvements in or relating to fluid pressure power systems for operating brakes andother devices
IPC: B60T13/24
Filed: 1946-08-08
Abstract: 615,803. Operating clutches. BENDIX AVIATION CORPORATION. Aug. 8, 1946, No. 23574. Convention date, Dec. 5, 1945. [Class 80 (ii)] [Also in Group XXXIV] In a unit for interposition between a pedaloperated hydraulic master cylinder and a hydraulic brake, clutch or other operating cylinder, and comprising a pneumaticallyoperated cylinder controlled by the pedal master cylinder and operating an auxiliary hydraulic master cylinder connected to the brake cylinder, the auxiliary master cylinder is arranged within the pneumatically-operated cylinder which comprises pistons arranged in tandem. As shown, pistons 32, 34 are connected by an auxiliary master cylinder 50 slidable through the fixed partition.44 of the cylinder 26. A tubular rod 62 fixed to member 22 on the end wall 24 of cylinder 26 extends into a piston 52 and has a sheath 80 which forms an annular passage connecting the port 20 to which a pipe from a pedal-operated master cylinder is connected, to the chamber 74 of piston 52 through ports 76 in the sheath. The inner passage 70 of the rod 62 connects the master cylinder 50 to the brake cylinders through port 30. A vacuum source is constantly connected to piston chambers 64, 96 by pipe 98 and normally to piston chambers 92, 94 by pipe 90, valve chamber 126, valve 102, port 86 and piston chamber 64. A piston 104 subject to the pressure in the pedal master cylinder through port 20 operates the valves and is attached to a reaction diaphragm 116. Normally, the master cylinder 50 and the brake cylinders are connected through the. tube 62, to the pedal master cylinder, but when the latter is operated, valve 102 is closed and valve 100 is opened to connect the piston chambers 92, 94 to atmosphere, through valve chamber 126 and port 84. The master cylinder 50 is then moved by the pistons 32, 34, first to seat the piston 52 on the end of the rod 62, thus cutting off the cylinder 50 from the pedal master cylinder and then forcing liquid from cylinder 50 through passage 70 to the brake cylinder, this movement being assisted by the pressure in the pedal master cylinder acting in the chamber 74 upon the end wall 66 of the cylinder 50. Since the chamber 74 of cylinder 50, to which the chamber of the valve piston 104 is connected, increases in volume with the movement of the pistons 32, 34, it is necessary in order that this movement may continue, to continue the pedal movement so as to maintain open the valve 100. The diaphragm since it is subject on one face to the vacuum in piston chamber 64 through port 86 and on its other face to the vacuum in piston chambers 92, 94 through passage 122 and ports 122 in the valve rod, chamber 126 and pipe 90 reacts on the pedal with a force proportional to that applied by the pistons 32, 34 to the brakes. A bleed screw-plug 108 for the hydraulic system is provided. The master cylinder 50 may instead be fixed to the end-wall 24 of the cylinder 26 and the piston-rod be carried by the pistons 32, 34.

Title: Process and apparatus for the separation of mixtures of solid particles into fractions according to specific gravity
IPC: B03B5/34
Filed: 1952-09-19
Abstract: 718,845. Washing granular material. MAATSCHAPPIJ VOOR KOLENBEWERKING STAMICARBON N.V. Sept. 19, 1952 [Sept. 24, 1951], No. 23594/52. Class 82(2) Mixtures of particles of different specific gravities are separated into fractions corresponding to a certain specific gravity of suspension in a separating suspension utilizing magnetically susceptible particles, the suspension having a specific gravity lower than the specific gravity of the lighter fraction to be separated. The light fraction obtained from the specific gravity separator is treated in a classifier (which separates according to settling rate). The classifier yields a fraction containing virtually all the light fraction, and one containing nearly all the suspension medium. The latter is returned to the process, whereas the former is treated magnetically to recover any suspension therefrom. The heavy fraction obtained from the separator is also treated magnetically to recover suspension. The suspension should be as stable as possible, one having 85 per cent. by weight of the particles smaller than 60 microns being mentioned. The separator may be a hydrocyclone or a jig. The classifier may be a hydrocyclone, a jig or a Dow classifier. If either of the two latter are used the suspension should be fed to them in a demagnetized condition. The cyclone 11 delivers the light fraction to a classifier 17 which returns the suspension particles direct to the receiver 7 via a collecting vessel 21. The classifier delivers the light fraction particles to two magnetic separators 19. 20, the latter working on the non-magnetic residue of the first. Similarly the heavy fraction is passed through the magnetic separators 13, 14. The medium recovered by the magnetic separators is returned by a thickener 22 to the receiver 7 into which new suspension and the material to be separated are also passed. The pump 10 supplies the mixture to the separator 11. A coarser range of particles than those dealt with in this process may be separated in a sink-and-float process and the media for both processes may be recovered by means common to both processes. The cyclone 11 .used in the process of the invention is preferably that disclosed in Specification 590,481. Specification 704,890 also is referred to.

Abstract: 873,306. Tensioning apparatus for endless conveyers. KEELAVITE CO. Ltd. Nov. 4, 1957 [Aug. 3, 1956], No. 24075/56. Class 78 (1). Endless wire web 1, used for conveying pulp, is kept in constant tension by means of two rollers 8, 11 which are pivoted at 10, 13 and are biased against the web. Automatic tensioning.-Roller 8 is biased by weight 14. Suppose the web stretches, then roller 8 falls to cause cam 41 to permit tappet 43 of hydraulic valve 44 to descend. This permits. pressure to be applied through inlet 44a, pipe 48, inlet 49D, outlet 49C, and pipe 56, to cause motor 26, acting through the gearing shown, to lower roller 11. This tautens the web and raises roller 8 back to its original position, at which it releases tappet 43 to close valve 44 to arrest roller 11. Raising of rollers from web for renewing the latter.-This is effected by manual master valve 70, manual lever 61, and manual control switch 80. Piston 19 is to raise roller 8, and motor 26 is to raise roller 11. Piston 19 is governed by valve 60, motor 26 is governed by valve 100, which in turn is governed by valve 90. Firstly, the operator moves control valve 70; to release pressure, via pipe 70 to valves 60, 90. and 100 (whilst operating electric switch 51 to cause valve 50 to cut-out valve 49, thus rendering inoperative the automatic tensioning described above). Then he moves lever 61 to cause piston 19 to raise roller 8 till it contacts switch 51. Then he moves switch 80 to operate valve 90 to cause valve 100 to pass pressure via inlet 100A, pipe 102 and pipe 50, to cause motor 26 to raise roller 11 till it operates switch 52. The web may then be removed for renewal.
