Abstract: 374,682. Purifying liquids. GAUNT, J. G., 6, Bream's Buildings, London.-(Exportingenieure f³r Papier-und Zellstofftechnik, Ges. ; 3, Duisburgerstrasse, Berlin.) Aug. 6, 1931, No. 22342. [Class 46.] The cylinder of a vacuum pump is cleared of residual gases by the introduction of liquid during alternate or other selected strokes. Liquid is contained in a reservoir 20 surrounding the cylinder and adapted to supply liquid thereto by the operation of a valve 21. Gas is exhausted from a vessel 10 through a valve 11 on the upstroke of the piston; in the succeeding downstroke the gas passes out through a valve 14 in the piston covered by liquid. On the next upstroke the valve 21 may be opened allowing the valve 11 to close and filling the cylinder with liquid which is discharged on the next downstroke. The gas is washed by its passage through the liquid above the piston and may be collected. By filling the vessel 10 with a suitable gas and the reservoir with liquid to be treated, the liquid may be aerated or sterilized.

Title: Improvements relating to cam actuated linkages
Inventor: BRIDGES WILLIAM EDWARD
IPC: B66B1/12
Filed: 1952-09-08
Abstract: 747,823. Cam linkages. METROPOLITANVICKERS ELECTRICAL CO., Ltd. Sept. 8, 1953 [Sept. 8, 1952], No. 22529/52. Class 78 (5). Cam-actuated apparatus for controlling a winch includes a plurality of profile cams M1, M2, which act through a control link C1, D1 mounted to turn about a fixed pivot D1, D2 to exert a control action on the winch, at least one cam being arranged to operate the link through a parallelogram linkage A2, B2, C2, D2 which may be deformed about pivots C2, D2 on the control link so as to bring the respective cam follower into or out of operative engagement with the said cam. As shown, linkage A2, B2, C2, D2 is controlled from man-ore lever M0, and linkage A1, B1, C1, D1 operates link E which controls mercury switch speed control device MS, of the kind set out in Specification 604,819. The linkages comprise D1, D2 fixed in space but rotatable, and D1, B1 completely fixed ; also the cams are so oriented that CA2 is lifted before CA1. If the lever M0 is in the position shown, then the operation of link E and therefore of the speed device MS is effected by cam CA2, because CA2 lifts first and the linkages then pivot about axis D to depress E accordingly. But, if the lever M0 is given a downward movement, linkage A2, B2, C2, D2 pivots about axes C and D to lift CA2 off its cam, so that then the operation of link E and consequently of the speed device MS is effected by the other cam, CA1. The device can be used for controlling a winch or a profiling machine.

Title: Improvements in switches, for controlling electrical circuits, actuated by electromagnetic means
IPC: H01H9/16
Filed: 1944-11-15
Abstract: 583,669. Partly electromagnetic switches. TILLS, J. W. Nov. 15, 1944, No. 22531. [Class 38 (v)] A contact 35 is moved selectively by hand over a series of contacts 64 and is then actuated electromagnetically into engagement with the selected contact, the contact-carrying rod 26 entering one of a series of locating holes 61b. In the form shown, there is an arcuate series of fixed contacts 64 and a common arcuate contact 62 and the bridging contact 35 is rotated over. these contacts by actuation of a knob 49 fixed to a sleeve 48 connected with lost motion to a plate 28 carrying the rod 26 which carries the contact 35. When the knob 49 is first turned, a striker 51 fixed to the sleeve 48 separates two co-operating contact springs 42 between which it lies, the contact springs being in the circuit of the electromagnet 15 so that this cannot be operated while the knob 49 is being turned. When the selected position is reached, this being determined by a ball 20 and a co-operating series of holes 19b, release of the knob 49 allows the contact springs to engage each other and prepare the circuit of the magnet 15. This circuit is then completed by rotation of a knob 53 which moves a rivet contact 57 into engagement with a contact 58. The magnet 15 then attracts its armature 24 which pulls down the rod 26 so that the contact 35 connects the selected contact 64 to the arcuate contact 62 and the rod 26 enters a locating hole 61b. An indicating lamp 59 is energized by a secondary winding energized by the primary winding 15.

Title: Improvements in or relating to a device for the automatic adjustment of the height of the blowpipe of oxy-acetylene cutting machines
IPC: B23K7/10
Filed: 1939-08-09
Abstract: 531,979. Dividing by fusion. MESSER & CO., GES. Aug. 9, 1939, No. 23020. Convention date, Nov. 30, 1938. [Class 83 (iv)] The distance between the nozzle of a blowpipe cutting machine and the surface of the work is automatically adjusted by a feeler gauge which controls an electromagnetic reversing, coupling connected with means for lifting and lowering theblowpipe. The nozzle is thus, kept. at the same distance from the surface of a large. workpiece throughout the cutting operation in spite of unevenness or lack of alignment of the surface. The blowpipe 1 is mounted in a casing containing a feeler gauge 2 which is pressed by a spring 5 against a thrust piece 7 in contact with a lever 9 which is engaged on its other side by a thrust piece 8 acted on by an adjustable spring 6. The lever 9 carries a spring-pressed pawl 10 which engages a groove in the end of a lever 12 engaged at its other end by a spring 13. The lever carries a mercury switch 14 which is connected to an electromagnetic reversing coupling 16 driven by an electric motor 15 so as to drive a screwed spindle 18 in either direction and thus raise or lower the blowpipe head. The blowpipe is first adjusted to suit the fuel gas or thickness of the work; by a knob 3 so that when in operation it will be at the correct distance from the work surface, this being shown by an index and scale. The current is then switched in, the head adjusted by a hand wheel 19 to bring the end of the gauge near the surface and the set-screw 4, which fixes the gauge when not in operation, is loosened so that the gauge touches the surface. The panel 10 thus tilts the switch 14 against the action of the spring 13 to set the screw 18 rotating so as to lower the head into normal position. If the gauge rises the switch 14 is reversed so as to reverse the rotation of the screw and raise the head. If the gauge slips off the_ work the levers 9, 12 are automatically uncoupled, and the, lever 12 is raised: by the spring 13 into contact with an adjustable stop 20 so as to switch in the drive for upward movement of the blowpipe and so preventing the blowpipe from coming into contact with the work. The gauge is then reset by hand. In order that the gauge may be-used on narrow work the head may be swung round the axis of the blowpipe by moving the machine arm by hand. The gauge may co-operate with a template instead of with'the work.
