Title: Improvements in or relating to ultra high frequency systems
IPC: H03F3/54
Filed: 1938-06-20
Abstract: 516,067. Valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 20, 1938, No. 18199. Convention date, June 19, 1937. [Class 40 (v)] In a high frequency amplifier having the anode grounded through a capacity, a network having 'characteristics to simulate the valve is provided and the signals to be amplified are applied to the valve grid and to the corresponding element of the network in push-pull and the output taken between the cathode and ground. Fig. 1 shows a circuit arranged with the network 8,9,10 forming a dummy valve and co-operating in push-pull with valve 1. The tank circuit comprises the capacity between plate 4 connected to the anode and the container 2 and a path of distributed inductance comprising the inner surface of the container 2 and the outer surface of the tube 5, tuning being effected by slides 12, 13. The input circuit 7 applies push-pull potentials to the leads 15, 16, which are tuned by strap 6. A strap 11 arranged substantially one-half of the operating wavelength along the tube tunes the leads 15, 16 in push-pull to zero impedance or to give inductive or capacitive reactance so that controllable regeneration or degeneration is obtained. Fig. 2 shows a modification in which the valve and network are placed on opposite sides of the tube 5 and within the container 2. With this arrangement filament heating is applied through the top portion of the tube and the input is applied through the lower portion of the tube. The filament is capacitively connected to the tube 5 by oppositely disposed half cylindrical plates 17 separated from the tube by mica spacers. With this arrangement the tank circuit comprises two sections connected in parallel. Fig. 3 shows an arrangement in which the leads 15, 16 are replaced by tubes 15<11>, 16<11> so that the input loop has substantially 100 per cent. coupling. A number of valves may be connected in parallel and co-operate with a single network which has a characteristic to simulate the valves, Fig. 4 (not shown).

Title: Improvements in or relating to the Manufacture of Collars
Inventor: LEE PHILIP GRAHAM
IPC: A41B3/00
Filed: 1966-04-27
Abstract: 1,155,693. Collars. P. G. LEE. 27 April, 1966, No. 18376/66. Heading A3V. A temporary stiffness for display purposes is imparted to a shirt or blouse collar having a top and bottom layer of non-iron top fabric and a cotton interlining with wet and/or dry crushproof properties by applying to the interlining, at least on the surface adjacent the top layer in the under collar region, an acrylic resin which is caused to adhere to the top fabric by the dry application of heat and pressure and which will be removed at the first wash. Many substances e.g. epoxy resins, carbamic acid esters and pre-condensates of ammino plastics e.g. methylol melamines, are suggested for rendering cotton top fabric non-iron; top fabrics of synthetic fibres e.g. polyamides or polyesters are dressed only by washing, bleaching, dyeing or possibly using softeners or hardeners. The cotton interlining is rendered crushproof by treatment with reactant resins, e.g. methyl compounds of triazine derivatives, or with N-free linking agents e.g. trialkyl sulphone derivatives. The acrylic resin may be a copolymer of methyl and ethyl esters of acrylic and methacrylic acid and is applied to fabric for interlinings by brushing and to pre-cut interlinings by screen printing. The interlining is preferably cut on the cross and may be bonded to the top fabric at areas not treated with acrylic resin by a permanent adhesive. As shown, Fig. 2, acrylic resin is applied to the top collar and under collar regions 8a and 8b of the interlining 3 on the surface adjacent the top layer 1 and permanent adhesive is applied at regions 4a, 4b on the surface adjacent the bottom layer 2. The interlining 3 is first sewn to layers 1 and 2, layer 1 and the interlining are turned back and the edge 11 of the garment is inserted between the inturned edges for the seam 12. The collar fold region 7 and button and button hole regions at the collar ends are not coated with acrylic resin.

Title: Improvements relating to the manufacture of artificial silk
IPC: D01F2/06
Filed: 1931-06-25
Abstract: In a process for the production of artificial silk of high tensile strength and high extensibility from viscose, by spinning into a sulphuric acid bath such as is known to produce a thread of tensile strength exceeding 2 grams per denier, the operation is conducted in two distinct zones, in the first of which the thread is stretched, and in the second of which it is relieved from some or all of the tension and treated for the first time with a washing agent, for example, water, or an aqueous solution of a salt, acid, or alkali. The stretching may be applied in any known manner, e.g. by means of rollers or rods, either driven or not, or by the use of a long bath, or by using a speed of draught which is higher than the speed of delivery of the spinning liquid.  By subsequently passing the thread over a roller rotating at a speed lower than that of a preceding roller, the tension on the thread is relieved, and the thread may then be washed by passing through a bath placed between the two rollers, or by applying the washing liquid to the more slowly rotating of the two rollers, or to the thread after leaving this roller.  Preferably the viscose used has a common salt ripeness of from 3 to 6.  In examples, (1) viscose of ripeness 5 is spun into a bath comprising 36,5 per cent sulphuric acid and also ammonium bisulphate and sodium bisulphate, drawn out at a speed of 32 metres per minute, passed through a washing liquid, and collected on a roller having a peripheral velocity of 25 metres per minute; (2) viscose of ripeness 6 is spun into a bath comprising 80 parts of sulphuric acid and 20 parts methanol, and subsequently treated as in (1); viscose as in (1) is spun into 72 per cent sulphuric acid, and the thread drawn by a draught roller at a speed of 33 metres per minute, passed through a washing bath and over a second roller at a speed of 25 metres per minute, and finally collected in a spinning box. Specifications 317,912, 323,731, [both in Class 2 (ii), Cellulose &c.], and 379,791 are referred to.

Abstract: 416,302. High-frequency transformers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. June 21, 1934, No. 18429. Convention date, Aug. 23, 1933. [Class 38 (ii).] A high-frequency coupling element operating over two or more wavebands comprises two very closely coupled coils one of which can be partially short-circuited and an auxiliary winding which induces a voltage in the coil coupled to the short-circuited coil to prevent current flow therein. The auxiliary winding may consist of a few turns connected in series with L3 and be so coupled to L2 that no current flows through this coil, the high frequency path being through the capacity between L1, L3 and the switch S. The tight coupling may be obtained by using stranded wires and employing part of the strands on the coil L1 and the remainder as the coil L3.

Title: Improvements in or relating to dustbin tipping devices
IPC: B65F3/12
Filed: 1957-06-17
Abstract: 820,471. Refuse vehicles; tipping bins. ZOLLER, H. June 17, 1957 [June 18, 1956], No. 19073/57. Class 78 (4). Damage commonly occurs to the swinging arms 10 (Fig. 6), by which dustbins are tipped into a refuse vehicle, when the swinging arms strike an obstruction on the ground as the vehicle moves. To avoid this, according to the invention, the arms have a hinge 11 which yields when the arms strike an obstruction as the vehicle is driven forwardly against the direction of the arrow (Fig. 6) and the lower part 13 of the arms is carried by a hinge 28 which yields if the lower end of the arm strikes an obstruction while the vehicle is being driven rearwardly. Movement about the hinge 28 may be constrained by a frangeable pin, by ball locks, or by a torsion bar spring, while the hinge 11 may be left free or may be controlled by a torsion bar spring. When the tipping apparatus is not in use the arm 10 may be held in the position shown in Fig. 2 by a line 17. The lower portion 13 of the arms has elastic buffers 14 engaging the lower end of a bin carried on a hook 4 (Fig. 2) on the closure 2 of the charging aperture. An elastic pad 27 on the lower portion 13 of the arms 10 bears against the abutment 29 on the arms 10. Movement of the arms 10 about the hinge 11 is limited by an elastic pad 22 (Fig. 4) which engages a fixed abutment plate 21. The tipping arms are driven from the shaft 7 and the initial shock of the bin striking the closure 2 may be reduced by engagement of a horn 6 (Fig. 2) fast on the shaft 7 with a shock-absorbing member 5 on the closure 2.
