Title: Improvements relating to automatic electric delay devices for thermionic valves
IPC: H04B1/16
Filed: 1931-09-02
Abstract: 385,667. Valve amplifying circuits. TAYLOR, P. H. and LAVINGTON, E., 36, Albert Road, Regent's Park, London. Sept. 2, 1931, Nos. 24652 and 25428. [Class 40 (v).] The power valve of a thermionic amplifier has its grid directly connected to the anode of the preceding stage, the correct grid bias of the power valve being obtained by a battery and resistance connected in its grid-cathode circuit. Fig. 1 shows a low-frequency amplifier 1 deriving its H.T. supply from terminals 2, 3, its anode circuit being directly connected with the grid of a power valve 26, which is supplied with high tension current from a mercury vapour rectifier 5. The transformer 7 has two secondaries 9, 40 supplying the filaments of the rectifier and power valve respectively, while transformer 12 supplies high voltage to the rectifier anode from one secondary 11 and a loud speaker field through a further secondary 18. The grid bias of valve 4 is determined by the drop across resistance 25 less the voltage of battery 29; 23 is the output transformer. The input to valve 1 is taken from a pick-up 32 through a tone compensator 33, as described in Specification 328,331, [Class 40 (v), Wireless signalling &c.]. Fig. 2 shows an arrangement generally similar to that of Fig. 1 as regards the valve coupling, but the system includes a protective relay arrangement in series with the mains supply to the rectifier anode transformer 12, whereby the supply is switched on at contacts 16, 17 after a predetermined interval, when the anode current of valve 1 through the relay coil 24 has reached a certain value. The armature 17 is held away from contact 16 by a coil 30 which is traversed by the grid current of valve 4 due to the battery 29. As the grid bias of 4 is obtained from the voltage drop across resistance 25 acting in opposition to the voltage of battery 29, the coil 30 does not release armature 17 until the bias attains the correct value. The loud-speaker field is energized from the secondary 18 of transformer 12, so that the loud-speaker is energized simultaneously with the application of H.T. voltage to the valve 4. The power stage may comprise several valves in parallel and the mercury vapour rectifier 5 may be replaced by a copperoxide or other suitable rectifier.

Title: Improvements in or relating to electric overload tripping devices
IPC: H02H3/08
Filed: 1927-09-21
Abstract: 277,973. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Sept. 21, 1926, [Convention date]. Cut-out arrangements.-A three-phase system T, S. R is protected on all three phases by a single current transformer b provided with two primary windings r, s wound in the same direction, one connected in each of two of the phases R, S, and a secondary winding c connected with a hot wire d. If excess current appears in either of the phases R, S, or if one of these phases is interrupted with the resulting increase of current in the other phase, the increased current in the secondary expands the wire d which opens at e the circuit of a no-volt retaining magnet f and trips the circuit-breaker. If, however, the phase T is interrupted, the single-phase current in the other two phases through the windings r, s cancel one another and there is no current in the secondary. But, in this case, a consequent pole will be formed at p which will attract the pivoted armature g and break the circuit of the no-volt retaining magnet at i.

Filed: 1955-08-30
Abstract: 798,300. Friction brakes. HOLZER, C., and BUSHE, M. VON, [trading as KIESERLING & ALBRECHT, T.]. Aug. 30, 1955 [Dec. 30, 1954; April 9, 1955], No. 24866/55. Class 103 (1). [Also in Group XXIV] A spring-loaded brake is combined with a clutch actuated by a pressure fluid annular diaphragm and having friction material inserts. The driving shaft 1 of a press is journalled in a stationary member 2 and has journalled thereon a driving pulley 19. Rigid with the shaft 1 is a diaphragm carrier 10 having an annular diaphragm 11 movable under fluid pressure from duct 12 to urge an intermediate member 5, in driving connection with the carrier 10, into contact with friction inserts 21 in the pulley 19. The inserts 21 are axially free in pulley 19 to further engage a clutch member 15 adjustably secured to an end plate 13 rigid with the shaft 1. An exchangeable element 22 is interposed between the inserts 21 to permit adjustment for wear. Threaded pins 6 rigid with the carrier 10 are threaded into adjusting nuts 7 in a brake disc 4 carrying a friction ring 3 engageable with the stationary member 2. The pins 6 are loaded by springs 9 to engage the brake 4, 3, 2 when the intermediate member 5 is not moved by the diaphragm 11. An electrically driven pump supplies oil to a ring main comprising a non- return valve, a pressure relief valve, an electrically operated control valve and an electropressure controller connected with the pump motor. A lead from the ring main operates the clutch when two switches on the press are closed, through the electrically operated control valve. This valve may be opened to release fluid pressure to the clutch and allow spring engagement of the brake by release of either of the two press switches or, for single-stroke operation by a switch automatically opened by the press. In a modification the stationary part 2 carries friction inserts similar to 21 which are engaged between a disc rigid with the shaft 1 and the brake disc 4.

Title: 3-keto-21-hydroxy-4,9(11),17(20)-pregnatriene and its esters and the production thereof
IPC: C07J75/00
Filed: 1954-08-30
Abstract: The invention comprises 3-oxo-21-hydroxy-4:9(11):17(20)-pregnatriene and its organic carboxylic acid esters (especially the esters of hydrocarbon carboxylic acids containing 1-8 carbon atoms), and the production thereof by concomitant hydrolysis and dehydration of a 3 - oxo - 11b :21 - dihydroxy - 5:17(20) - pregnadiene 3-ketal bimetallic complex, followed, if desired, by the action of an acylating agent. The said bimetallic complex may be prepared by reducing a 3-ketal of a 3: 11-dioxo-5: 17(20)-pregnadien-21-oic acid ester with lithium aluminium hydride, and may be treated with a dilute water-miscible strong acid in a two-phase system.  Reference is also made to the production of the free 21-hydroxy compound by dehydration of 3 - oxo - 11b :21 - dihydroxy - 4: 17(20)-pregnadiene or by concomitant hydrolysis and dehydration of a 3-oxo-11b :21-dihydroxy - 5: 17(20) - pregnadiene 3 - ketal. In Example (1), the methyl ester of 3: 11-dioxo-4: 17(20) - pregnadien - 21 - oic acid 3 - ethylene glycol ketal is reduced with lithium aluminium hydride in benzene and ether and the resulting solution is refluxed with dilute hydrochloric acid to produce 3-oxo-21-hydroxy-4: 9(11): 17(20)-pregnatriene, which is isolated by chromatography.  In further examples, the product of (1) is esterified by treatment in the presence of pyridine with: (2) acetic anhydride; (3) benzoyl chloride; (4) propionic anhydride; (5) b -cyclopentylpropionyl chloride; (6) phenyl-acetyl chloride. Additional esters are listed.

Title: Method of horizontally or substantially horizontally laying a pipeline or other object in a trench in a formation underlying a body of water
Inventor: JONGBLOED LODEWIJK JOHANNES SC
IPC: E02F5/12
Filed: 1968-05-27
Abstract: 1,163,508. Laying under-water pipe lines. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 27 May, 1968, No. 25229/68. Heading F2P. [Also in Division H2] A method of horizontally, or substantially horizontally, laying a pipe line in a trench in a formation underlying a body of water comprises the steps of making the trench in the formation by removing part of the formation, passing into the trench a liquid that will sink in the trench and fill the trench either simultaneously with, or separately from, the trench forming operation, and laying the pipe line in the said liquid in the trench in a horizontal, or substantially horizontal, position. The liquid may be viscous and have plastering and gel properties and may include carboxy methyl cellulose. The liquid may also be loaded with sand. In one example a pipe line, made by welding together pipe sections on board a ship, is gradually slipped on to the bottom of the sea and a yoke, carrying a number of nozzles supplied with water under pressure, is placed, straddle-legged, over the pipeline and drawn along it, the sea-bottom underlying the pipe being removed by the jet action of the nozzles which are directed downwardly. The rear end of the yoke carries outlets for the trench filling liquid comprising a gel made of 6% by weight bentonite and water, which is pumped into the trench. As the yoke proceeds along the pipeline the latter is gradually lowered into the gel-filled trench. The bentonite has gel qualities which assist in preventing the collapse of the trench side walls and plastering qualities which help to seal the surfaces of the trench. The gel liquid, which may incorporate gel breaking agents, gradually breaks down after a time so that the trench collapses over the pipeline. If desired, the pipeline can be buried deeper by running the yoke for a second time, and the gel may eventually be removed by pumping action. In another method, e.g. for laying a pipeline across a river, the pipeline is floated into position and then lowered into a previously dredged trench filled with gelled liquid. Suitable filling liquids are water with guar gum, floc gel, and polymers, e.g. polyacril compounds, the liquids if necessary being suitably loaded with grains, e.g. sand.

Title: Improvements in labelling machines
Inventor: ROSE ALFRED GERMAN
IPC: B65C3/12
Filed: 1955-09-02
Abstract: 814,529. Labelling machines. ROSE BROS (GAINSBOROUGH) Ltd. Nov. 22, 1956 [Sept. 2, 1955], No. 25238/55. Class 73 Articles such as bottles 29 are labelled by a machine comprising a label carrier 11 rotating about a horizontal axis and arranged above a conveyer 28 upon which the bottles lie in a horizontal position, the carrier being arranged to receive labels in succession from a magazine 18, and the labels which are made adhesive at 27 being applied to the bottles by rotating the latter whilst still on the conveyer; the conveyer is moved in time relationship with the label carrier. In the construction shown the bottles 29 in shoot 52 are fed by a rotatable member 53 to cradles 33 fitted to the conveyer 28. The conveyer is driven intermittently to bring each bottle in turn to a rest position beneath the continuously rotating label carrier 24. Beneath the bottle, at this position, is a roller 37 which is driven by a chain 46 from a shaft 45 and which is carried by a pivotally mounted arm 41 actuated by a cam 44 on the shaft 45. The timing of the mechanism is such that when a label 17 on the carrier 11 reaches the applying position the cam 44 raises the roller 37 to bring the bottle into contact with the label, whereby the bottle, in contact with moving label and roller, is rotated to effect transfer of the label to the bottle. The transfer is assisted by a pressure roller 38 on an arm 39 and by rollers 36 on each cradle 33, and to enable the rollers 36 to remain in contact with the bottle when the latter is lifted portions 48 of the guides 47 of the chain conveyer 28 are slidably mounted on plungers 49 and are urged upwardly by springs 51. The labels from a stack 18 are fed to the carrier through rollers 16 by a pivoted suction nozzle 19, and are held on the carrier partly by suction and partly by a cam-operated gripper 21 which holds the leading edge of the label. Before reaching the applying station each label is gummed at 27, or is rendered adhesive by heating, and at the applying station the suction is cut off and air under pressure is applied to assist the transfer.
