Title: Improvements in self-engaging and self-sealing pipe couplings especially applicable to flight refuelling purposes
IPC: B64D39/06
Filed: 1951-05-21
Abstract: 729,815. Pipe couplings. FLIGHT REFUELLING, Ltd., and WORLIDGE, R. F. May 21, 1952 [May 21, 1951], No. 11863/51. Class 99 (1). In a pipe coupling of a kind particularly applicable to refuelling aircraft in flight in which a number of spring-loaded latches 11 mounted on a socket member 5 is adapted to engage a spigot member 27, the socket is provided with a valve assembly comprising a poppet valve 17 adapted to engage a seat 23 on a spring-loaded slidable sleeve 22. A number of levers 18 having a fulcrum in the socket are connected at their ends to the valve and the sleeve so that the valve is opened as the sleeve is pressed inwards by the entering spigot. The seat 23 is constituted by a conical sealing ring which is secured to the sleeve by a clamping ring 24 and serves to seal the sleeve and spigot at its inner periphery, and to seal the sleeve and socket at its outer periphery. The base of the socket is formed by a collar 6 which carries the levers 18 and is secured by a nut 7 which screws into the socket at 5i and is locked in position. The nut and collar form a spherical socket for a ball member 9 carried by a hose pipe, sealing rings being provided at 8 and 10. A valve in the spigot comprises a spring-loaded plunger 28 which is slidable in a cylinder 30 carried by a spider 30c, and is actuated by the valve 17: A sealing ring 29 on the plunger engages a seat in the spigot or the valve 17. The cylinder is vented by a passage 34 in the spider and by a filtered opening 35 in the plunger. Specification 676,430 is referred to.

Title: Means for supplying auxiliary fuel to internal combustion engines
Inventor: BEVIS WILLIAM ALBERT
IPC: F02N99/00
Filed: 1950-05-13
Abstract: 690,876. Starting. C.A.V., Ltd. April 26, 1951 [May 13, 1950; July 5, 1950], Nos. 12004/50 and 16762/50. Class 7 (v). In means for supplying auxiliary liquid starting fuel to an internal combustion engine, comprising the combination of a hollow twopart body a. b, adapted to receive a puncturable capsule i containing ether or other liquid, and a suction piece c attached to one of the body parts, such as part a, and adapted to puncture and enter the capsule i while the two parts of the body are being interconnected, it is arranged that the part a, to which the suction piece is attached, is adapted for connection to the engine manifold, not shown. The suction piece c has a helical thread n, a pointed end d, and a central channel e leading at the inner end to radial passages f adjacent the point d and at the outer end to a connection h leading to the engine manifold. Upon assembly of the body parts a and b the point d pierces the capsule i, and when the engine is rotated by a starter the ether is drawn into the manifold; air enters the two-part body through grooves, not shown, to ensure complete discharge of the ether. The device may additionally be provided with a well o that communicates with the channel e through radial parts q whilst air is admitted to the well along a passage j from the body. When the point d punctures the capsule i air enters the latter until a lip s in the body part b encounters the underside of a rubber or like washer r on the suction piece c whereupon further inflow of air to the capsule is stopped. Continuing advance of body part b into part a causes an increase in pressure of the entrapped air resulting in displacement of fuel from the capsule to the well; meanwhile the lip s slides over the washer r to the position shown, thereby re-establishing communication of the body with atmosphere. The stem of the suction piece may have longitudinal grooves therein to facilitate admission of air to the capsule, and a stirrup t may be used to prevent accidental separation of the body parts. The air may pass through a filter m before entering the device.

Title: Television camera control apparatus
Inventor: PIETERS LEON ANDRE
IPC: H04N5/073
Filed: 1961-04-05
Abstract: 1,002,130. Automatic phase control systems. PYE Ltd. April 3, 1962 [April 5, 1961], No. 12171/61. Heading H3A. Horizontal sync pulses are transmitted to a remote television camera unit from a control station A and automatically controlled in timing by a variable delay generator so that sync pulses received back at the control station A from the camera bear a fixed time relation to master control pulses at the control station, irrespective of any signal transit delays to and from the camera. As shown, sync pulses are applied through a fixed delay circuit 2 to a monostable delay generator 3 generating pulses whose trailing edge actuates a pulse generator 4 sending pulses through a cable 14 to a camera unit B. These pass through a gate 15 and delay circuit 16 to initiate the horizontal scan. Pulses centred on flyback pulses then return back along the cable, with opposite polarity, and pass through a gate 13 to a differentiating and clipping circuit 11 producing a narrow pulse to clamp the amplitude of a sawtooth generator 7 whose peak is rectified at 9 and controls at 8 the timing of the rear edge of the delay generator 3, which determines the timing of the control pulses sent to the camera. Delay circuit 2 ensures the sawtooth has started before the earliest returning pulse (when a short cable is used), and delay 16 that the incoming and return pulses are separated in timing. In Fig. 3 (not shown), narrow pulses pass through an OR gate instead of delay 16 and the output of scan generator 17 is fed back to the OR gate to prolong the flyback time. A high level clipper produces pulses from the centre of the flyback pulse at instants later than the incoming narrow sync pulses, and retransmits them back along the cable. Alternatively, gates 13, 15 and delay 16 may be omitted if a separate return cable is used.

Abstract: 1,247,248. Processing spent nuclear fuel. KERNFORSCHUNG m.b.H. GES. FUER 7 March, 1969 [13 March, 1968], No. 12248/69. Heading G6R. In separating plutonium and uranium from fission products by extraction of an aqueous solution with an organic solvent and re-extraction into the aqueous phase, the organic phase is treated with an aqueous tetravalent uranium solution to reduce tetravalent plutonium to the trivalent state so as to remove it from the organic phase. For example in reprocessing spent nuclear fuel by extraction of an aqueous solution with tributyl phosphate in dodecane, plutonium forms stable complexes with radiation decomposition products monobutyl phosphate and dibutyl phosphate; these complexes are decomposed and the plutonium extracted by treating the organic solution with an aqueous solution of uranium (IV) nitrate which contains hydrazine nitrate. Reference is also made to di-2-ethylhexyl phosphoric acid as the organic solvent.

Abstract: 392,351. Lubricating gas-compressors. BERNAT, R. and BERNAT, H., 5, Rue de Moscouß, Bordeaux, Gironde, France. April 28, 1932, No. 12266. Convention date, April 28, 1931. [Class 12 (iii).] A compound gas-compressor is provided with a single pipe connecting the crank case to the inlet valve of the low pressure cylinder so that oil drawn up from the crank case through said pipe is forced by the compressed gas successively through each cylinder in order to lubricate all the cylinders. The compressor comprises a low pressure cylinder 1, and a high pressure cylinder arranged side by side on the crank case 3. Gas enters, e.g. from the separator of a refrigerating plant, through a pipe 21, the intake to the cylinders being regulated by two rotary sleeve valves operating as described in Specification 224,758, [Class 12 (ii), Lubricating passages &c.], and mounted on a common shaft chain-driven from the crank shaft. Spring- pressed delivery valves are provided. A pipe 30 connects the intake valve 11 with the crank case 3, and oil rises from the latter to the valve, and passes into the low pressure cylinder 1, as disclosed in Specification 224,758. Some of the oil is deposited in, and lubricates the cylinder 1, and the remainder is discharged in suspension in the partly compressed gas through pipes to the second valve and thence into the high pressure cylinder. The invention is applicable to compressors having any number of cylinders.

Title: Improvements in and relating to the manufacture of reinforced concrete
IPC: B28B23/22
Filed: 1945-05-16
Abstract: 596,678. Prestressed concrete structures: posts. BILLIG, K. May 16, 1945, No. 12266. [Classes 20(i) and 20(iv)] Fully prestressed reinforced concrete structures, i.e. structures in which the tensile reinforcement is prestressed to such a degree that no tensile stresses are allowed to develop in the concrete under the designed load, are prestressed in successive stages, the initial stage being effected by transmitting the tension of the wires as compression to the partly matured concrete and the succeeding stage or stages following up the increase in strength of the concrete with time and being effected by the introduction of supplementary wires with a plastic cementitious bonding in the concrete and allowing the bonding to harden and the supplementary wires to introduce additional compression to the concrete, the tension of the wires being such that in the finished beam the concrete is permanently under compression. As shown in Fig. 1, the wires 21, which are equally distributed throughout the structure after the manner specified in Specification 561,135, are stretched and released to compress the concrete 24, when the latter has attained a strength of half the specified cube strength, say after three days. The concrete is stored until aged to the full specified strength (say after one month) and the second prestressing then takes place. The wires 33 are stretched in and along the recesses 34 provided at the perimeter of, or in hollows within, the cross section of the concrete unit 24 and the recesses are filled with quick-hardening cement 35 while the wires are kept on their tensioning devices. The wires are released as soon as the cemented grooves are able to transfer the forces exerted on this second set of wires. The second prestressing may also be carried out by transferring the force in the wires 33 by means of anchor plates and filling the grooves or hollows 34 with protecting material (e.g. asphalte) which prevents the wires 33 in the grooves 34 from bonding with the concrete 24. The application of the process to hollow floor units and to lattice poles is also described.
