Title: Improvements in or relating to electric signal transmission systems
IPC: H03G7/02
Filed: 1942-10-12
Abstract: 560,702. Automatic volume control. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 12, 1942, No. 14281. Convention date, Oct. 13, 1941. [Class 40 (v)] A compressor circuit comprises a balanced amplifier circuit, connected to a rectifier so that the output of the rectifier will control the gain of the amplifier circuit, and a feed-back circuit independent of the gain-varying rectifier circuit for neutralising spurious frequency components introduced from the rectifier circuit without reducing the gain for the desired signals. Fig. 3 shows the invention applied to a compressor unit of a sound recording system in which an audio-frequency input is fed to the primary of transformer 30 the secondary of which feeds push-pull amplifiers 34, 35 coupled to a second pair 50, 51 feeding an output transformer 53. Part of the output is fed over leads 69, transformer 68 and potentiometer 70 to an amplifier 73 feeding a full-wave rectifier 76 which supplies an A.V.C. voltage over lead 87 and resistance 88 to the grids of valves 34, 35 to effect volume compression. The degree of compression is determined by the setting of potentiometer 70 while the level at which compression begins is determined by the setting of potentiometer 83 providing a delay bias for rectifier 76. Conductors 90, 91 provide a negative feed-back path from the common grid return circuit of valves 50, 51 to the corresponding point of valves 34, 35. This neutralises spurious frequencies which are introduced by the A.V.C. line due to inefficient filtering at low frequencies and which would be present in the output in the event of any unbalance of the circuits. U.S.A. Specification 2,255,683 is referred to.

IPC: B25B27/20
Filed: 1960-04-25
Abstract: 920,877. Inserting spring rings. AUTOMOTIVE ENGINEERING Ltd. April 25, 1961 [April 25, 1960], No. 14446/60. Class 61. A magazine hand tool for applying circlips to spindles, pins and the like, wherein an end circlip of the stack is disposed opposite an opening in a slide slidable in a slideway, has hand grip means for imparting reciprocable movement to the slide in a direction transversely to the stack whereby the slide moves the end circlip into a position where it is engaged with the spindle, pin &c. and in so doing the slide blocks the movement of the circlip then at the end of the stack but permits such movement when the slide is returned to its initial position. As shown, the tool comprises a two-part hollow casing 10 shaped to provide a hand grip and on one side of which is an opening through which extends a hand lever 12. One end of the lever 12 pivots about a pin 13 encircled by a helical spring 16 which tends to move the lever out from the opening. A peg 23 fixed to the hand lever 12 extends through a longitudinal slot 22 in a second lever 21 which is pivoted at 20 to the casing. A slideway 24 projects beyond the two-part casing, there being mounted within the slideway a relatively thin slide 25 having fixed to it a pin 26 which projects between the arms of a fork formed at the extremity of the second lever 21. The other end of the slide is formed with a circular slot 28 slightly greater than a semicircle and having diverging ends 29. The slide is slotted at 30 to provide resilient fingers which lightly grip the circumference of a circlip. The slideway 24 is formed with a channel in which the slide 25 is guided and across which a wall 31 extends outside the casing, the wall 31 together with the bottom of the channel forming a slot through which the slide may extend. The part of the slideway 24 immediately opposite the wall 31 is provided with a circlip receiving hole 33. Fixed to the face of the slideway 24 on the opposite side thereof to the wall 31 is a bracket member comprising a plate 34 extending at right angles to the slideway and having fixed thereto two angle section strips 35 which provide a holder for a stack of circlips which are threaded over them. The lowermost clip may pass through the hole 33 in the slideway and rest on the plate 31. The plate 31 is provided with a small hole in which is disposed a ball 36 which is spring pressed into the channel of the slideway through the hole in the circlip to prevent the circlip from passing out through the slot 28 until the hand lever is operated. A spring loading device applies downward force to the uppermost circlip of the stack.

Title: Improvements in and relating to the production of bulked yarns
Inventor: STARKIE DAVID
IPC: D02J1/22
Filed: 1960-04-26
Abstract: 970,157. Finishing yarns. ENGLISH ROSE Ltd. April 7, 1961 [April 26, 1960], No. 14507/60. Heading D1F. Multifilament thermoplastic yarn is bulked by a continuous two-stage process. In the first (crimping) treatment, the running yarn is stretched longitudinally to a predetermined extent and a greater proportion of the elongation at one side of each filament than at the other side is rendered permanent by passing the stretched yarn through a heating zone and establishing a temperature gradient across each filament between relatively hot and cool sides thereof so that the hot side retains a greater proportion of the applied elongation than does the cool side and each filament tends to assume a helically crimped formation. In the second (bulking) treatment, the length difference between the two sides of each filament is accentuated and the bulk effects thereby enhanced: the cool side of each filament is shrunk by feeding or overfeeding the running yarn, under such longitudinal restraint as prevents the full formation of "in-phase" helical crimps in the individual filaments thereof but with these filaments under minimum tension, through a zone in which the yarn is heated uniformly, there by resulting in an "out-ofphase" formation of crimps in the filaments. In the latter heating zone, the yarn may contact the surface of e.g. run in a groove in, a heated roller the peripheral speed of which may be higher than the speed of the yarn (in order to increase the "out of phase" effect and filament separation). In the illustrated apparatus for carrying out the bulking treatment (following a first treatment using apparatus described in Specification 890, 110) the tensioned yarn 1 with the crimp therein not fully developed at the roller 2 (the grooved roller described in the prior specification) passes over a small arc of a smooth roller 3, then recover a large arc of the periphery of roller 6 within a groove, Fig. 2 (not shown) therein, and is delivered from the apparatus by rollers 4 and 5 at aspeed less than the input speed. The roller 6 is heated e.g. by an internal electrical element, and is maintained at a constant elevated temperature. A freerunning pulley 8 carried on a pivotable arm 7 enables the yarn to be withheld from contact with roller 6 e.g. while the roller is being heated to the required temperature or if crimped but unbulked yarn is required to be produced and the rollers 4, 5, may also be opened and closed in synchronism with movements of the arm 7.

Title: Improvements in and relating to the production of ethylenediamine and its derivatives
IPC: C07C209/48
Filed: 1945-06-08
Abstract: Ethylenediamine or N.N1 - diacylethylenediamine is prepared by hydrogenating amino acetonitrile under pressure in the presence respectively of at least 15 mols. of an inert diluent per mole. of amino acetonitrile or of at least 4 moles. of a saturated aliphatic carboxylic acid ester per mole. of amino acetonitrile and in the presence of a proportion of hydrogenating catalyst amounting to at least 25 per cent by weight of the amino acetonitrile.  Suitable diluents are ammonia, methanol, ethanol or other aliphatic alcohols. Esters which may be present are the methyl-, ethyl-, propyl-, butyl-and higher alkyl esters of formic-, acetic, propionic, hydroxy-acetic acids or the higher esters of the aliphatic mono- or polycarboxylic acids.  Specified catalysts include nickel alloy, copper chromite, nickel or cobalt catalysts supported on kieselguhr, silica gel or similar inert support.  Hydrogenation may be conducted at 25-300 DEG  C. and at pressures above 1000 atmospheres and preferably between 200 and 1000 atmospheres.  The reaction may be carried out continuously and when conducted in the liquid phase the catalyst volume is preferably at least as great as the solution volume.  When N.N1-diacylethylenediamine is produced it may be hydrolysed to ethylenediamine.  In examples, aminoacetonitrile is hydrogenated, using ammonia as diluent and a cobalt catalyst prepared by reduction of cobalt oxide or a nickel-aluminium alloy catalyst of the Raney nickel type to give ethylene diamine and in the presence of methyl formate instead of ammonia using the same cobalt catalyst, to give N.N1-diformyl ethylene - diamine. Specifications 439,274 and 458,454 are referred to.  The Specification as open to inspection under Sect. 91 states that the aminoacetonitrile is hydrogenated in dilute solution or in dilute solution with an aliphatic organic acid ester present, in the presence of a hydrogenation catalyst.  This subject-matter does not appear in the Specification as accepted.
