Title: Improvements in or relating to jet reaction means
Inventor: ELLIOTT ALBERT GEORGE
IPC: F02K1/00
Filed: 1952-03-10
Abstract: 722,338. Jet-propulsion plant. ROLLSROYCE, Ltd. March 6, 1953 [March 10, 1952], No. 6225/52. Addition to 693,681. Class 110 (3). [Also in Groups XXVIII and XXXIII] Jet-propulsion means as claimed in the parent Specification has the sealing element in contact with the part-spherical surface formed by piston-ring type sealing means. The sheetmetal jet pipe 10 has secured to its end a T- sectioned strengthening ring 14, one web 14b of which supports an extension 15 of the jet pipe. A strengthening ring 17 is attached to the upstream end of the tail pipe 11. End rings 18, 19 are attached to the strengthening rings 14, 17. The end ring 18 comprises a bolting flange 18a and a portion 18b in the form of a zone of a sphere with its centre on the axis of the ring. The end ring 19 has a bolting flange 19a and a portion 19b in the form of zone of sphere with a beaded end 19c. The beaded end 19c is formed with a pair of axially-spaced circumferential grooves 20, the upstream walls of which are radial and the downstream walls of which are frusto-conical. 'These grooves are occupied by piston rings 21 which have external faces of part-spherical form to engage the internal surface of the portion 18b of the ring 18 and frustoconical faces to co-operate with the downstream walls of the grooves. These walls cause the gas pressure in the pipe to force the rings against the inner surface of the part 18b. The jet pipe 10 is supported from the vehicle structure 13 by a retractable spindle 23 which engages the hollow boss 25b of a bracket 25 bolted to the strengthening ring 14. The external surface of the boss 25b forms a bearing for a second bracket 26 attached to the strengthening ring 17 of the tail-pipe 11. The hollow boss 26a of the bracket 26 has a part-spherical bore which houses a collar 27 fitted on the external surface of the boss 25b. This arrangement allows rocking movement of the jet pipe 10 with respect to the vehicle structure 13 and of the tail pipe 11 with respect to the jet pipe 10 and vehicle structure 13. Modifications in which the part-spherical sealing surface is attached to the tail-pipe and in which the sealing rings are mounted in the outer member and co-operate with a part-spherical sealing surface on an inner member are described. A heat shield may be secured to the downstream end of the jet pipe 10 to extend axially over the ring 18. This shield is preferably formed in two arcuate parts.

Abstract: 367,460. Electrolysis. NADAL y RAMON, R., 50, Calle San Francisco, Badalona, Barcelona, Spain. May 12, 1931, No. 6568/30. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 10, 1930.] [Class 41.] In the electrolytic manufacture of metallic compounds of low solubility from anodes of the metal, the process is effected intermittently without continuous flow of the electrolyte, each stage being stopped and the vats emptied before exhaustion of the compounding ions and before the quantity of the compound affects the reaction adversely ; any small quantity of the compound which may be dissolved in the electrolyte is precipitated and the electrolyte regenerated before return to the vat. The electrolysis is carried out at ordinary temperatures and diagrams are not employed. In the manufacture of white lead the electrolvte is sodium chlorate of 3‹ Be, supersaturated with carbonic acid injected at 1À5 atmospheres, and the current density employed is 0À5 amps. per square dcm. at 1À5 to 2À5 volts. The vats are emptied after 40-45 minutes, the precipitate is removed and the electrolyte regenerated with carbonic acid and returned to the vats. For the manufacture of lead hydroxide, the carbon dioxide is omitted, other conditions being the same ; in this case any dissolved lead hydroxide is removed from the electrolyte after emptying of the vat by addition of a suitable acid or by injection of air.

Title: Improvements in and relating to pulse receiver circuits
IPC: G01S13/10
Filed: 1946-03-05
Abstract: 606,170. Valve relay circuits. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). March 5, 1946, No. 6849. [Class 40 (vi)] A receiver for pulses of high-frequency oscillations comprises a control device operated upon receipt of one of a train of pulses, the device being maintained in its operative condition for a pre-detennined time interval after reception of pulse and means for extending this interval on reception of a second pulse of the train. In the Figure, pulses of oscillations from aerial 10 are applied to the amplifier 12, which is broadly tuned to the frequency of the oscillations, further amplified in the stage 13 and applied to the diode rectifier 40, thus giving negative pulses at grid 43. Valve 14 comprises a triode and pentode section cross coupled and operating as a single stroke multivibrator circuit, so that on receipt of a negative pulse at grid 43 the triode which is normally conducting is cut-off and the pentode section. rendered conducting, the potential of the anode 53 falling and applying a negative pulse to the grid 60 of the normally conducting valve 15. The current flowing in the valve 15 is reduced and the relay 16 releases. Capacitor 58 which is normally charged through resistors 55 and 56 from the battery 29, loses charge on receipt of the negative pulse at grid 60 and only slowly charges up again as the time constant of the charging circuit is long. On receipt of a second pulse from aerial 10, the multivibrator circuit having returned substantially to 'its original condition, a negative pulse is again produced at grid 60 thus dispersing the charge which capacitor 58 obtained from the battery 29 and causing the relay 16 to remain in its in-operative condition. By adjustment of resistor 56 the relay 16 will remain in the in-operative condition during the whole of the time that a train of pulses is received at aerial 10. If the receiver is used for indicating radio echoes, a transmitter 17 coupled to aerial 10 is keyed from source 18 and the receiver is rendered inoperative by means of the gating circuit 19 for the duration of the period during which the transmitter is being keyed.

A surgical clip applicator comprises a body having a guideway 28 for receiving clips 30 in aligned end-to-end relation, means 34 for urging clips through the guideway and jaws 62 with seats 63 located in advance of the guideway by a distance equal to the length of a clip for receiving the front ends of a clip. The clip applicator body comprises upper and lower sections 14, 16 hinged together at the rear end and releasably secured together by a clamping band 25. The lower section has a longitudinal recess defining the guideway 28 for flat clips of U-shape or V-shape and the upper section has a longitudinal recess 32 in which a spring-pressed push member 34 is slidable to push the clips from the guideway at the front end. Forceps comprising strips 54, 56 attached at each side of the lower portion have jaws 62 spaced from the front of the guideway by a distance equal to the length of a clip. The leading clip is held between seats 63 on the forcep jaws and the front end of the guideway. During application of the clip the applicator is held at a small angle to the skin so that points 72 projecting out of the plane of the legs and rear end of the clip enter the skin. As the forcep jaws are pressed together the clip is deformed to secure the edges of the wound. The clips remaining in the applicator are prevented from leaving the guideway by an abutment 50 which may be lifted by applying pressure to a lever 46 against a spring 44. The push member 34 has a bifurcated front end 35 which passes on each side of the abutment as the last clip is pushed out of the guideway for use. A pin 40 on the push member is normally slidable in a slot 38 in the upper section 16 but may be rotated into a notch (not shown) at the rear of the slot to hold the push member in retracted position. A clip remover 77 (Fig. 25) comprises spring strips 78, 80 secured at one end and forming jaws 96, 98 at the other, the strips being so curved that on pressing them together at divergent portions 84, 85, the jaws move apart. In use the jaws are placed between the legs of a clip and moved apart to detach the clip from the wound. For loading the applicator, the body sections of the applicator are opened and the clips glued to a rod 74 (Fig. 2) are inserted in the guideway. The sections are then closed and secured and the rod is withdrawn.
