Abstract: 428,970. Carbonating liquids. BOSMANN SODATOR APPARATEBAU GES., W., 26, Schulzendorferstrasse, Berlin. April 27, 1934, Nos. 12792 and 12793. Convention dates, April 27, 1933 and June 14, 1933. [Class 14 (i)] Apparatus for carbonating water comprises a container a divided by a resilient diaphragm b into two chambers, the inner one of which serves as a measuring chamber b<1> for receiving the fresh water and the outer as a delivery chamber a<1> for receiving the carbonated water, both chambers being adapted to be connected simultaneously to a carbonating device or, alternately with that, to a fresh water supply m and outlet conduit o respectively. The mouth of the measuring chamber is upwardly directed and is connected, for example, by means of a rotatable double three-way cock d, with that end of a tube e or group of tubes provided with dispersing elements e<1>, into which the carbon dioxide supply conduit f opens, while the upwardly directed end of the delivery chamber communicates with the other end of the tube so that during the carbonation period liquid and gas flow in parallel through the tube. The resilient diaphragm may be, as shown, a rubber bag provided with ribs or grooves n, and the container a may be made in two parts, whereof the detachable cap part is preferably made of rustless alloy, enamelled iron, ceramic material, or glass. The double three-way cock d may be provided with a pressure relief conduit connecting the spaces in front of and behind the plug thereof. The spindle of the cock is sealed by means of a rubber ring threaded thereon, and which, under the pressure of a helical spring, bears with a conical or spherical packing surface against the similarly shaped surface of a nut placed over the spindle like a stuffing box and adapted to be screwed into the barrel in order to relieve the plug of the cock of axial thrusts. The carbonation tube e is preferably provided near its inlet end to the delivery chamber with a gas release valve v. To prevent loss of gas when the apparatus is not in use and when charging the carbonated liquid into bottles, a double-seated quick closing valve g is inserted between the delivery chamber a<1> and the outlet pipe o, one packing of which valve s provides a seal for the threeway cock and the other t for the spindle packing. For selectively employing the outlet pipe for open delivery in filling bottles under pressure, a conical resilient insertion member q surrounded by a protective bell is adapted to be connected to the outlet pipe o for filling bottles.

Title: A tuner for tuning a circuit over two different frequency ranges
IPC: H03J5/02
Filed: 1953-05-08
Abstract: 756,940. Radio receiving apparatus. STANDARD TELEPHONES & CABLES, Ltd. May 8, 1953 [Aug. 9, 1952], No. 12913/53. Class 40 (5). A tuner for tuning a television receiver to both the VHF and UHF bands comprises a cylinder housing elements for continuously tuning the receiver in the UHF waveband and a turret surrounding the cylinder and mounted coaxially therewith and upon which are mounted the elements for tuning the receiver to selected channels in the VHF waveband, the arrangement being such that in one position of the turret the UHF tuning elements are connected into the circuits of the receiver and that in each of the remaining positions corresponding VHF tuning elements are connected into circuit. Fig. 4 shows the turret, comprising a plurality of panels 42, 43, the VHF panels having tuning components mounted on their undersides as shown more clearly in Fig. 5 and the two UHF panels being connected to the UHF tuning circuit formed within the inner cylinder 49. The inner cylinder comprises four longitudinally extending cylindrical cavities, of which two 60, 63 are shown in Fig. 5; these co-operate with movable plungers, of which two 61, 65 are shown, to provide tunable coaxial lines for tuning the radio-frequency, local oscillator, harmonic-selector and mixer circuits of the tuner. The harmonic selector serves to select the third harmonic of the local-oscillator output and inject that together with the incoming radio frequency signal into the mixer circuit. The plunger 61 comprises a variable inductance, variation of which effects the local-oscillator tuning. The remaining plungers operate as variable capacitors. The turret is rotated as a whole by means of the shaft 48 having the knob 47 attached to one end. When the turret is set to the UHF position, tuning of the UHF circuit is effected by rotation of shaft 79 driven from a knob 74. Attached to shaft 79 is a threaded sleeve 79a rotation of which causes the plate 80 to which the tuning plungers 61, 65 are attached to move longitudinally with respect to the cylinder 49 and thus alter the tuning of the tuning cavities within the cylinder. Fine control of tuning is effected by rotation of knob 88 which causes rotation of shaft 86 through the cord 84, the fine tuning condenser 87 being driven by rotation of the shaft 86. The fine tuning condenser forms part of the oscillator circuit for both VHF and UHF tuning and thus the fine tuning knob 88 is effective in all positions of the turret.

Abstract: 769,376. Sewing machines. SINGER MANUFACTURING CO. May 4, 1955 [May 17, 1954], No. 12917/55. Class 112. [Also in Group XXXIV] Lubricating. A sewing machine is provided with a bed 1 containing a pair of rotary loop-takers 42, 43 each associated with a bobbin-case opener. Each loop-taker shaft 46 and each opener shaft 51 is formed at the bottom with a helical groove 66 which is embraced by a sleeve 65 and which extends into a reservoir 57 for lubricant. As the shafts 46, 51 rotate lubricant is pumped up along the helical grooves and fed to the looptakers and to other machine mechanisms. One of the shafts 51 communicates with a conduit 94 leading to an auxiliary reservoir 80 provided in the upper arm 3 of the machine, excess of oil draining from the reservoir through a conduit 95 and flowing into a channel 102 in a gear 54 from which it is thrown by centrifugal force to lubricate contacting surfaces between gears 54 and 53 and between gear 53 and a gear mounted on shaft 11. The lubricant in the auxiliary reservoir 80 is transferred by a wick 81 to a well 82 containing an absorbent pad 83. The wick 81 is normally out of contact with the lubricant but is placed in contact by being depressed by a manually-actuated plunger 85 against the action of a spring 84. The plunger may be held in the depressed position by giving it a quarter turn. Lubricant in the well 82 is carried through a radial wick-filled aperture 88 to the bearing 8 for the main shaft 9 of the machine, and is carried by a wick 89 to the take-up mechanism. Excess lubricant drains to a sump 91 from which it is carried by a wick 92 to other mechanism in the head 4 and by a wick 93 to needle feed mechanism. The loop-taker shaft 46 is hollow and has a radial bore 73 for conveying lubricant from the helical groove 66 up inside the shaft to a cartridge comprising wicking 75 and a metal cap 76 having a passage leading towards the raceway of the bobbin-case carrier. The flow of lubricant is controlled by a by-pass containing an outlet controlled by an adjustable valve. Lubricant draining on to the top of the reservoir 55 passes through a filter before re-entering the reservoir. The feed mechanism for the machine is as described in Specification 724,419.

IPC: B21D9/07
Filed: 1952-05-23
Abstract: 757,888. Making drain traps or other bent duct members; stamping. BENDZ, Ltd., and ACKERMAN, S. Jan. 22, 1953 [May 23, 1952], No. 13069/52. Classes 83 (2) and 83 (4). A method of producing a duct member of other than simple rectilinear form, such as an angle bend or U-shaped drain trap, includes acting on a length of duct by a cold deformation process of such character as to produce the required longitudinal configuration, trimming at least one end portion of said deformed length to produce a rim which lies in a plane substantially perpendicular to the centre line of the duct, and pressing said trimmed end. portion locally to produce an internal circumferentially extending recess adapted to receive a sealing ring. To form a drain trap, Fig. 1, a length of metal duct 20 is given a first bend by apparatus, Fig. 8, wherein the duct or tube 20, disposed over a mandrel 18, having an articulated end 26, and held in a fixed guide 17 and pivoted member 23, is bent around a curved part 21 of the pivoted member 23 as that member is swung around its pivot. One limb of the bent pipe is then bent to form the U-bend by similar apparatus, the pivoted member 23 of which being suitably shaped to hold the elbow part of the pipe. The end of one limb is then trimmed off and pressed to form a flange 47, Fig. 1, which serves to retain a union nut 48. The end of the other limb is also trimmed off perpendicularly to the axis of the pipe and the bent and trimmed pipe is held by shaped clamping dies 52, 53, Fig. 4. A succession of punches, in co-operation with a shaped end of the dies 52, 53 form an enlarged end 60 of the pipe and, by curling, a circumferential internal recess 70, Figs. 5, 6 and 7. A rubber sealing-ring 72 of circular, elliptical or oval cross-section is inserted into the recess so as to project slightly therefrom to form a fluidtight seal against the end of another pipe 59. Before the ring is placed in position the trap may be pierced at the bottom of the U and an internally-threaded sleeve 73, closed by a screw plug 74, secured thereto. The recess 70 may be of rectangular, V-shaped or part-circular crosssection. According to the Provisional Specification the bending and recess-forming operations may be carried out simultaneously. Specifications 757,884, [Group XXVIII], and 757,976 are referred to.

Title: Latch mechanism for temporarily latching the machine head in a tilted position to the base of a sewing machine
IPC: D05B75/06
Filed: 1954-05-06
Abstract: 747,535. Stays for hinged articles hinges. SINGER MANUFACTURING CO. May 6, 1954 [May 11, 1953], No. 13208/54. Classes 65 (1) and 65 (2). Stays.-A sewing-machine head 1 hinged at 3 to a base 2 is held in a tilted position by means which will allow lowering of the head at a limited speed, but will lock if this speed is exceeded as, for example, in the event of the head falling freely. The holding means comprises a rack 11 pivoted to a bracket 12 beneath the head 1 and engageable by a pivoted pawl 35 formed so that its nose 36 is positively moved into a tooth space of the rack on movement of the rack, the pawl being biased in the opposite direction by means which will withdraw its nose from the rack before it comes into contact with a tooth if the speed of movement is below a predetermined maximum. In the arrangement shown, the rack is guided by a slot 16 engaging a fixed screw 20, and the pawl 35 is pivoted on a triangular plate 25 loosely mounted on the screw 20 and carrying a screw 29 projecting through the slot 16 so that the plate 25 keeps the pivot of the pawl in constant relation to the rack. The pawl has a tooth 37 so placed in relation to the nose 36 that one or other of these parts is always in a tooth space of the rack, engagement of the tooth 37 with any tooth of the rack forcing the nose 36 into another tooth space, and a oounterweighted tail 38 of the pawl biases it to bring the nose 36 clear of the rack. In upward movement of the rack the pawl will be rocked positively and freely by engagement of rack teeth alternately with the nose 36 and tooth 37 ; in slow downward movement, there is time for the counterweight to swing the nose 36 clear of the rack, after it has been moved into a tooth space by contact of the rack with the tooth 37, so that lowering of the head 1 is not hindered, but if a given speed is exceeded the nose cannot swing clear before being engaged by a tooth of the rack so as to stop the movement. Hinges.-Each hinge 3 comprises an element 4 pivoted in the base 2 and a stud 5 removably secured by a set-screw in a bore in the base of the machine head 1.

Thermionic relays.-A thermionic valve relay in which the input circuit is controlled by a moving-coil or other switch contact, and the output comprises the winding of an electromagnetic relay, is characterized by the feature that the plate and filament supply as well as the gridbiasing voltage are taken directly from alter. nating-current mains. As shown, the plate supply is derived from the primary 18 and the filament supply from the step-down secondary 20 of a transformer shunted across the mains 16, 17, Grid bias is' taken from a tapping 24 on the primary winding to the moving arm 4 of n moving-coil instrument A which is fed through leads 6 by the operating current. As the arm 4 moves down into contact with the grid lead 5. the new biasing voltage causes the operation of a load relay 10 in the plate circuit. The biasing voltage derived from the main may be adjusted to any desired value, and may cause the relay 10 to open instead of close the load circuit when the input contact 5 is made. Or the moving-arm contact 5 may be arranged to operate one or other of two valves according as it swings in one direction or the other.
Patent GB-133719-A (GB)
IPC: F01L9/10
Abstract: 133,719. Constantinesco, G. March 21, 1918. Regulating; valve-gear.-Beat or lift valves are actuated by impulses transmitted through liquid columns by cam-actuated plungers. The invention is described as applied to a Diesel engine having six cylinders, the exhaust, admission, and liquid-fuel injection valves of which are acted upon by liquid under pressure stored in transmission pipes 1 - - 6 leading to casings a, b, c containing cam-actuated plungers 14 housed adjacent the open ends of the transmission pipes. The pipes are of small cross-section, e.g. two mm., and the liquid therein may be maintained at a pressure of 1000 lb. per sq. in. Referring to Fig. 1, inlet and exhaust valves e, d are included in a transmission system, the normal pressure of which is maintained bv a pump delivering into a reservoir g. Pipes k, h connect the reservoir to the pipes 1 - - 6 communicating with the valve chambers, one of which is shown in Fig. 10. The valve stem 31, Fig. 10, carries a member 32 which is retained in its uppermost position by a plunger 34 subject upon its lower face to the normal pressure in the transmission system. A reservoir which is located in the passage leading to the underside of the plunger ensures that the impulses transmitted to this plunger shall be delayed until after the opening of the valve. The opening of the valve is effected by a plunger 33 which is acted upon by the individual impulses transmitted through liquid contained in a pipe 36 connected to one of the pipes 1 - - 6 of the pressure system. The plungers 14 for producing the impulses are actuated by rocking-arms 12 which bear upon cams 11 carried by a shaft rotating at onehalf the speed of the crank-shaft, or at a reduced speed if each cam is provided with more than one swell. A pressure-relief valve c<1> returns surplus liquid to the supply pump. The fuel-injection valves f are opened similarly to the admission and exhaust valves by a separate pressure system to which fuel is supplied by a pump delivering into a reservoir m connected to a transmission pipe n having a relief valve o. A small reservoir which serves to damp the impulses is located in each of the pipes leading from the cam-actuated plungers in the casing c to the injection valves. The valves are closed by springs. The time of opening of the fuel-injection valves may be altered by adjusting the positions of the cam rollers; the quantity of fuel injected may be varied by adjusting the normal pressure of the fuel in this transmission system.
