Abstract: 256,607. Foamite Firefoam, Ltd., (Assignees of Rollo, W. R.). Aug. 10, 1925, [Convention date]. Fire-extinguishing by foam.-In an invertible foam-type extinguisher comprising outer and inner containers respectively containing foammaking solutions, the inner container 3 is provided with one or more portholes 5 near its upper end through which the inner solution is projected into the outer solution on inversion of the extinguisher, the total area of the portholes being less than the area of the mouth of the inner container. The inner container has a seat member 8 below the portholes and coacting with the usual stopple. A drain-hole 9 is provided for the space between the seat member and the wall of the inner container. A partition plate 4 near the top of the outer container 1 provides a restricted annular opening for the flow of the outer solution into a mixing space defined by the partition. On inversion, flow of the outer solution by this annular passage intersects the flow of the inner solution by the portholes. The provision of several portholes renders pressure equalizing means unnecessary for the inner chamber; but a pressure equalizing tube 7 is provided for the outer chamber.

[Also in Groups I and XXIX] Iii a press for separating liquid from a mixture of .liquid and solid comprising a vertical series of pistons and open-ended cylinders (see Group I) the lowermost press piston 1 is first raised by a hydraulic piston 10' and when the resistance exerted by the cake formed in the. space 6 is greater than the weight of the,next, upper piston 1a and the cylinder 5 secured to it by sleeves 9. the piston 1a and cylinder 5 move upwards, the sleeves 9 meanwhile sliding along four splined shafts 2. At the end of the pressing operation the parts resume the positions shown in the Figure with the piston flanges resting on fixed rests 44 or.45. To remove the cake the shafts 2 are rotated simultaneously by a motor 47 thus causing each sleeve 8 to rotate in bearings in the flange 4a of the piston 1a. -The rotation of the threaded part of each sleeve in the flange 7 of the cylinder 5 causes the cylinder to move downwards over its associated piston 1 until the cake which now rests on top of the piston 1 is exposed to view and may be removed by hand. The shafts 2 are then rotated in the opposite direction to restore the cylinders to the positions shown in the Figure. If rotation. of the shafts 2 is continued after the cylinder 5 has touched the piston 1a the cylinder forces the flange 4a of the piston against buffer springs 60 of which one is provided on each sleeve 8 actting between the flange 4d and a stop 59.

Abstract: 797,919. Slipping clutches. DALL'OLIO, V. June 19, 1956 [June 23, 1955], No. 18938/56. Class 80 (2). A coupling for conveying rotary motion between shafts 10, 11 includes a plurality of short shafts 13 arranged parallel to and evenly spaced about the axis of shaft 10. Each shaft is rotatably supported and carries a tubular member 20 made of a resiliently compressible material such as natural or synthetic rubber. Shafts 13 have nuts 23 by means of which members 20 may be compressed axially causing a radial expansion and increasing its resistance to radial compression. The arrangement operates inside a cup-shaped end portion 12 of shaft 11. Cap 12 includes an inner surface with a plurality of evenly-spaced curved hollows accommodating members 20. Excessive torque causes members 20 to be compressed and pass over points 26 of hollows 25. Hollows 25 may be arranged so as to prevent slip, thereby enabling the device to be used as a torsional shock-absorber.

Title: Method of reducing the swelling capacity of synthetic alginate skins
IPC: A22C13/00
Filed: 1956-06-20
Abstract: The swelling capacity of alginate sausage skins prepared by precipitation of alginate solutions in solutions of calcium salts is reduced by treatment with acid to convert the skin wholly or partially to alginic acid and then reconverting the alginic acid to calcium alginate by treatment in a solution of a calcium salt, the treatments being repeated, if desired.  An example is concerned with extruding an 8 per cent aqueous solution of sodium alginate from an annular nozzle into a 10 per cent calcium chloride solution, conducting the tube so formed through 3 per cent hydrochloric acid, washing, conducting the tube through a 10 per cent solution of calcium chloride containing 1 per cent of calcium hydroxide in suspension, washing, and softening the tube in a solution containing 15 per cent of glycerol and 15 per cent of calcium chloride, the tube so treated having diminished swelling capacity, greater resistance to bursting under pressure, and decreased dilatability.

Title: Improvements in and relating to pulse systems
IPC: G01S13/10
Filed: 1947-07-17
Abstract: 649,528. Pulse circuits ; radiolocation. BRITISH THOMSON-HOUSTON CO., Ltd. July 17, 1947, No. 19173. Convention date, June 1, 1942. [Classes 40 (vi) and 40 (vii)] An impedance is connected to a valve or valves so that a pulse appears in opposite sign at two points on the impedance and is absent from an intermediate point. Normally, the screen of valve 1 is maintained at a sufficiently low potential that the incoming signal 10 is ineffective. A square wave generator 75, synchronized with the transmitted pulse, controls a gate or strobe pulse generator 20 which feeds, through amplifier 24, a negative-going gating pulse to cut off valve 2. The rise in anode potential is fed to the screen of valve 1 which passes the input signal for the duration of the pulse. The potential of the anode of valve 1 comprises a negative pedestal 42 due to the valve being switched to the conducting state together with a negative-going signal pulse 43. The anode resistor 31 is returned to a tapping on potentiometer 30 forming the anode load of valve 2. As the gate pulse 27 reduces the anode current of valve 2 a positivegoing pulse appears at the anode so that the tapping may be adjusted to feed a positive pedestal with a negative-going signal to valve 3. Similarly, by adjusting the tap on potentiometer 31, the signal pulse only may be fed to the peak value voltmeter 73, 74. The output from valve 3 is fed through a paraphase amplifier 4, 5 to the vertical deflection plates of a cathode-ray tube 6, the horizontal plates being energized from a saw-tooth generator 76 controlled by the gate pulse generator 20. A horizontal shift is provided by a square wave 87 which reverses with the position of the aerial axis to provide a side-by-side display 92 of an echo. The pulse 40 after inversion in amplifier 44 is employed to brighten the trace of a cathode-ray tube 7, the vertical plates of which are fed from a marker pulse generator 80. By rotation of the ganged control 20, 80 the marker pulse may be brightened to show coincidence with the selected echo pulse.
