Abstract: 105,826. Giddin, W. T. June 12, 1916. Ammonia and other gases are purified by passing them through a quantity of the same gas liquefied while it is evaporating, or in some cases the evaporation may be prevented or restrained by cold or pressure. Impurities of higher boiling point and soluble impurities are retained in the liquid. In the apparatus shown, the liquefied gas is admitted by a pipe 2 into a vessel 1, which may be covered with non-conducting material, and a cock 7 is closed. The impure gas is passed by a pipe 3 into the liquid and passes away purified by a pipe 4. The contaminated liquid may be drawn off when desired through a cock 10 and a pipe 5 into a vessel 6 where the liquid is allowed to evaporate, and the vapour is drawn by a pump through a pipe 11 and passed into the main current of unpurified gas for purification by the process. The impurities may be drawn off by a cock 13 or they may be washed or steamed out. The vessel 6 may be dispensed with and the contaminated liquid dealt with in the vessel 1. Several purifying-vessels may be connected in series. To restrain the evaporation of the liquid by pressure, the closure of the cock 9 is adjusted, a pressure gauge being provided.

Title: Apparatus for cutting pseudo sound record tracks for musical instruments
IPC: G11B3/36
Filed: 1944-06-08
Abstract: 587,582. Making pseudo sound records. REEVE, L. F. June 8, 1944, No. 10964. [Class 40 (ii)] A machine for cutting a pseudo-record for playing in a gramophone or phonograph comprises a recording head having a stylus which is operated by a hydraulic transmission producing reduction from a waveform templet. The recording head A, Fig. 1, is formed with a cavity A<1>, in which a body a<2>, which carries the cutter (not shown), is supported by two diaphragms a, a<1>, the former sealing the cavity against egress of fluid, and the latter being perforated to permit flow of fluid through it. The cavity A<1> communicates with the bore b<5> of. a pump B in which a plunger b, carried in. cap b<6>, is reciprocated. The cavity A<1> and bore b<5> are filled with fluid, such as mineral oil, through a vent normally closed by plug d, air being allowed to escape from the cavity by releasing plug d<1> closing one end of bore b<5>. The upper part of the head A is threaded to receive knurled rings c, c<1> by which the head is suspended and clamped in the required position on rails g, g<1>, Fig. 3, on the recording machine, the head being formed with flats a<3> engaging the rails. Manual adjustment of the lateral position of the head is effected by operation of a knob o on the end of a lead screw o<1> which passes through a bore a<4> Fig. 1, in the recording head and carries a nut o<2> engaging in a slot a of the head. Vertical adjustment of the head is effected by operation of rings c, c<1>. The head is suspended above the blank to be cut and cuts a circular groove thereon, the blank being held by clips e<2> on a turntable e which is driven through Worm gearing i, Fig. 4, which is carried on a shaft j<1> which is slidable on its bearings under the control of a cam.

Title: Improvements relating to electron-discharge devices
Inventor: WANG CHAO CHEN
IPC: H04L9/22
Filed: 1953-03-10
Abstract: 779,985. Velocity-modulated tubes. SPERRY RAND CORPORATION. March 10, 1953, No. 11027/57. Divided out of 779,733. Class 39(1). In a device in which velocity modulation of an electron stream is converted into densitymodulation and including means capable of establishing a magnetic focusing field along the path of the stream, the electrons have a radial component of velocity at at least one point within the focusing field and in consequence perturbations in the cross-section of the stream are produced, the result being that out-ofphase electrons between the bunches are extracted from the stream at a place where they are at a greater radius than the other electrons. The stream is in the condition of " perturbed Brillouin flow " and preferably also the magnetic field is increased along the stream to compensate for the increased space-charge repulsion as the bunches form, as described in Specification 779,733. It is shown that in these circumstances the outer electrons perform oscillations about the Brillouin equilibrium envelope (itself a tube of oscillating cross-section) and that the out-ofphase electrons can be collected at the extreme of their oscillation without interfering with the bunch electrons. In the figure are shown in a klystron, buncher gap 12, cascade buncher gap 13, cathode gap 14, equilibrium envelope of out-of-phase electrons 22, equilibrium envelope of bunch electrons 21, oscillation envelope of out-of-phase electrons 26, oscillation envelope of bunch electrons 25, projection 28 collecting outof-phase electrons ; the whole being rotationally symmetrical about axis 11.

Patent GB-1278041-A (GB)
Title: Positioning mechanism
Inventor: SPENCE-BATE HARRY ARTHUR HELE
IPC: F16H25/00
Filed: 1968-03-07
Abstract: 1278041 Cams H A H SPENCE-BATE 4 June 1969 [7 March 1968] 11180/68 Heading F2K [Also in Division G2] A positioning mechanism for use in a microfiche camera or projector includes a rotatable drum 15 having a cam groove 16 thereon engaged by a follower 17 secured to a frame 11 to be moved along rails 13, 14 parallel to the cam axis of rotation, the follower being precisely located at predetermined positions by engagement in respective notches 19 (Fig. 1). In Fig. 1, the drum 15 is spring-connected to its shaft 18 and has a helical cam groove 16 and return groove 20 interconnected by transfer slots 21, 22, 23. As the cam drum 15 is rotated in direction F, the frame 11 is advanced by the action of the continuous wall of the cam groove 16 on the follower. When a notch 19 has just passed the follower, the drum 15 is reversed and the follower engaged and located by the notch. Subsequent rotation of the drum 15 in direction F continues the advance of the frame 11. Reversal of a motor driving the shaft 18 is controlled by a microswitch 59/60 (Fig. 3) actuated by a two-part cam 50/51 on a shaft 52 connected to the shaft 18. A disc 51 freely rotatable on the shaft 52 is connected to a disc 50 secured to the shaft 52 by springs 55. Pegs 54 on the disc 51 co-operate with shoulders 61 on the disc 50 to limit relative rotation therebetween. During advance of the frame 11 the shaft 52 is rotated clockwise (Fig. 3), the disc 51 being held by the roller 58. At the limit position shown, corresponding to a notch 19 passing the follower 17, the rise 56 of disc 50 lifts the roller 58 to close the contacts 59, 60 to reverse the motor, and hence shafts 18, 52. The springs 55 cause disc 51 to catch up with disc 50, the cam surface 57 holding contacts 59, 60 closed while the notch 19 engages the follower 17. On restarting the motor to rotate the drum 15 in direction F, the roller 58 drops into the next cam recess, opening the contacts 59, 60. The depth of a notch 19 may be adjustable by means of a sliding wall portion (Fig. 7, not shown). Fig. 6 shows a modification allowing reversal of the drive to the frame 11 at almost any point on the cam groove 81, a deflector block 82 being provided adjacent each notch 86. In a microfiche positioner, a second mechanism as described above is mounted on the frame 11 to move a film carrier normal to the direction or motion of the frame 11.

Title: Machine for winding the stators of electric motors
IPC: H02K15/085
Filed: 1942-08-10
Abstract: 563,932. Coil winding apparatus. MICAFIL, Ltd. Aug. 10, 1942, No. 11183. Convention date, Aug. 5, 1941. [Class 35] The stator 2 is centred in a ring 3 which is indexed by a pawl 4 and ratchet 5. The winding head 6, which comprises a roller 8, and two intermeshed toothed rollers 9a, 9b, is carried on a rod 10 to which an endwise to- and-fro movement through the stator is imparted by a two-armed lever 14 and connecting rod 13. Adjustable links 16a, 16b also impart an up-and-down movement to the head which brings it at the end of each traverse level with the bottom of the stator slots. The rod 10 is also given a swinging movement about its axis by means of a rack 18 engaging a pinion, in order to form the end turns of the coils. The movement of the rack is derived from a cam 24, a slotted arm 23, connecting rod 22, lever 21, connecting rod 20 and lever 19. Coacting with the head to form end loops are fingers 7a, 7b rotatable in supports 30a, 30b, and actuated from the lever 21 by a connecting rod 26, double-armed lever 27, and connecting rod 28. The fingers come into action at the end of each traverse to direct the wires into .the bottom of the slots. The number of turns completed is registered by a counting mechanism operated by the axial movement of the head. The carrier ring 3 may be moved backwards and forwards mechanically when the winding pitch is greater than an angle of 100 degrees. In order to form the coil ends, readily removable horns are placed in the slots adjacent to the wound slots.

Abstract: 812,949. Hydraulic pit props. COAL INDUSTRY (PATENTS) Ltd. July 20, 1955 [April 20, 1954], No. 11348/54. Class 20(2) [Also in Group XXIX] The hydraulic supply to the extensible hydraulic pit prop A is increased when the prop is extended and contacts the mine roof and the resistance to further extension exceeds a predetermined value. Fluid is supplied through a valve B and passages Q, M, R to the prop A and through a branch pipe S to a spring- loaded piston J which when the pressure in the system exceeds this predetermined value, is depressed to connect the passage S to an intensifier piston G on the low pressure end FL of which it acts to move the piston to the right and produce high pressure by means of the small piston in the passage R to the prop. The piston G of the intensifier is either returned to the left when fluid is first supplied to the prop or as shown in this modification when it moves to the right engages and opens a valve Y to release fluid through a pressure reducing valve Z from the pipes M, Q, S and allow the piston J to be returned by its spring R, S to connect the low pressure end FL of the intensifier to exhaust and allow the piston G to be returned to initial position by the pressure fluid retained in the high pressure end FS by the valve Z.

Title: Clamp-type track brake for railway vehicles
Inventor: PONS PAUL HENRI
IPC: B61K7/06
Filed: 1955-04-20
Abstract: 773,249. Track brakes. ETABLISSEMENTS SAXBY. April 20, 1955, No. 11419/55. Class 103 (1). In a clamp-type track brake for railway vehicles two brake clamps, which are vertically movable, are situated one on each side of a rail, the clamp outside the track being movable and fitted to one end of a lever tilting around an axis parallel with the rail, the other end of said lever being subject to the weight of the wheel rolling along the other rail when in the operative position. In the embodiment illustrated in Figs. 1 and 2, in which Fig. 1 illustrates the unclamped position and Fig. 2 the clamped position, the rails 1 and 2 forming the track are borne by bearers 3 and 4 respectively. A clamp 5 is disposed between the rails on beam 15 which bears by one end on a stationary support 18 on part of bearer 4. A clamp 8 is disposed on the outside of the track on tilting lever 7 which pivots, together with beam 15, about a common axis 14. The other end of lever 7 carries a roller 9 which bears against the bottom surface of a rigging bar 10 comprising a ramp 11. The lever 7 bears through a roller 16 upon a stationary plate 17. When the bar 10 has been moved longitudinally in a direction parallel with rail 2 by a motor (not shown), the ramp 11 causes roller 9 to descend and pivots lever 7 about roller 16, bearing against stationary plate 17. During this movement, clamp 8 approaches clamp 5 to leave a separation less than the width of the wheel tyre, and simultaneously shaft 14 rises relatively to roller 16 and lifts the corresponding end of beam 15 which pivots about stationary support 18. This double pivoting movement of the lever 7 and beam 15 (the beam 15 in this embodiment representing two beams), causes clamps 5 and 8 to rise to a height H greater than height h (Fig. 1) to increase the clamping surface on the tyre. In an alternative construction, shown in the unclamped state in Figs. 3 and 4, the arrangement differs from that described above in that the roller 16 and plate 17 are replaced by a pair of levers 20 which are pivoted to a movable linkage controlled by a single motor, which also controls the translational movement of bar 10 ; the bottom end of each lever 20 having a roller 21 which bears upon a fixed rolling track 22, the upper end of lever 20 bearing against the end 19 of lever 15.
