Title: Improvements in the manufacture of resistors
Inventor: CHEETHAM REGINALD JAMES
IPC: H01C3/02
Filed: 1952-02-14
Abstract: 721,366. Wire-wound resistors. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Feb. 13, 1953 (Feb. 14, 1952], No. 4001/52. Class 37. A bifilar resistor comprises two resistance wires held together in a skin of lacquer which embraces them. The invention is particularly concerned with very fine resistance wires. The term lacquer is used in its broadest sense and includes enamels and similar coating compositions. In Fig. 1 two loop wire lengths 9 are stretched side by side from copper terminal strips 2, 3 secured to glass tube former 2. The wires 9 are coated with insulating enamel which is hardened by passing a red-hot iron slowly along close to the wires. The process is repeated and coatings join together and by surface tension draw the wires into close proximity to form a skin of enamel embracing the wires. A layer of wax is then applied around the tube 1 and terminal strips 2, 3 and the loop 9 wound loosely over the wax layer. The terminal strips 2, 3 attached to tube 1 by soldered and enamelled bindings 4, 5 leading to terminal wires 6, 7 are separated at their overlapping ends by a mica strip 8 so that a small inductance neutralizing capacity is introduced. In Fig. 2 the loop 14 is wound around a flat core consisting of resin-bonded paper 13 and terminal strips 11, 12 covered by Cellophane (Registered Trade Mark) adhesive tape 19. The resistors may be sealed in wax or in a glass or fibre tube which can be filled with an inert gas. Details of suitable lacquers and enamels are given in the Specification.

Patent GB-772635-A (GB)
Title: A process for preparing a phthalic acid by oxidizing di-isopropylbenzene
IPC: C07C51/265
Filed: 1955-02-14
Abstract: Phthalic acids such as terephthalic acid are prepared by oxidizing the corresponding diisopropylbenzene with oxygen or an oxygencontaining gas in a liquid medium consisting mainly of an aliphatic carboxylic acid or mixture of such acids in which the di-isopropyl-benzene is soluble, water being removed from the reaction mixture during the reaction to maintain the water content of the reaction mixture below 5 per cent by weight.  Catalysts such as compounds of heavy metals which can exist in different valency states such as manganese or cobalt or mixtures of such compounds with or without barium compounds may be present. Aliphatic acids mentioned are acetic, propionic and butyric acids. The methods described to maintain the water content below 5 per cent are (i) passing more oxygen or oxygen-containing gas through the reaction mixture than is necessary to effect oxidation, thus removing water vapour in the surplus gas, (ii) adding to the reaction mixture either at the commencement or during the reaction, a water-binding reagent which does not interfere with the course of the reaction, (iii) adding to the reaction mixture a component which at reaction temperatures distils off as an azeotropic mixture with the water to be removed, or (iv) withdrawing reaction mixture continuously or intermittently from the reaction vessel, isolating the desired reaction product and recycling the remaining liquid after reduction of the water content (a) by addition of a water-binding reagent or (b) by distillation with or without use of an azeotroping liquid. Waterbinding reagents used in methods (ii) and (iva) above are anhydrides or mixed anhydrides of those aliphatic carboxylic acids having 2 to 4 carbon atoms per molecule such as acetic anhydride or mixtures of such anhydrides.  An apparatus for conducting the process of method (ivb) without an azeotroping liquid is described.  Examples illustrate the oxidation of p-di-isopropylbenzene in acetic acid as solvent with air in the presence of cobalt acetate and manganese acetate as catalyst under pressure and at elevated temperature, (1) wherein acetic anhydride is added to the mixture at the beginning of the reaction, and after reaction terephthalic acid is filtered from the mixture, further p-di-isopropylbenzene, catalyst, solvent and acetic anhydride being added to the filtrate and the oxidation being repeated several times, the results being compared with a series of similar oxidations in which no acetic anhydride is used; (2) wherein reaction mixture is continuously withdrawn from the reaction vessel, terephthalic acid is filtered therefrom and water is removed from the filtrate by distillation, the distillation bottoms being recycled to the reaction and fresh p-di-isopropylbenzene, solvent and catalyst being added intermittently.  Specification 737,439 is referred to.

Title: Improvements in Apparatus for Signalling Under Water.
Inventor: CARNEGIE ALFRED QUINTIN
IPC: G10K7/06
Filed: 1918-03-14
Abstract: 130,688. Carnegie, A. Q. March 14, 1918 Subaqucous audible signals.-In a siren apparatus for signalling under water the signals are pro duced by relative axial movement between the rotor and stator. In the construction shown in Fig. 3, the rotor 2 is driven by a water turbine 3 on the spindle 4, the operating water also being used to produce the sound. The spindle carries a valve 5 adapted to close the holes in the stator 1 when the rotor is depressed. The spindle is reciprocated either directly from a signalling key 19 or, as shown, by operating the valve 14 controlling the piston 12 fixed on the spindle. A number of hollow indiarubber balls 20 are provided for cushioning purposes. As applied to a surface ship, an outer tube is secured over an aperture in the ship's bottom which extends inboard to a level above the sea. The siren apparatus is mounted in this tube so that it can be withdrawn or protruded as desired. Fig. 7 shows the apparatus adapted for use in a submarine vessel. When the siren is withdrawn within the outer tube 23, communication with the open water is cut off by a stop valve 33 operated by means of a screw 37. In a modification, the siren is fitted to a hand or power pump which by delivering whole or half-strokes produces dash or dot signals. The siren may be attached to the lower end of a tube adapted to be slung overboard, this tube being connected to a. water supply. A damping-plate or disk may be fitted to the siren to prevent excessive jumping.

Title: Control of internal combustion engines
IPC: F02D9/00
Filed: 1936-02-14
Abstract: 456,098. Regulating. MULLER, E. L., 215, Kurf³rstendamm, Berlin. Feb. 14, 1936, No. 4542. Convention date, April 17, 1935. [Class 7 (vi)] In engines in which liquid fuel supplied by a pump, together with air, is admitted to the cylinder during the compression stroke, the quantity of fuel delivered by the pump is regulated by hand simultaneously with the regulation of the air supply, and also automatically by the vacuum in the induction pipe so that increasing suction diminishes the fuel supply. A yielding connection is provided in the hand control of the air throttle so that the throttle movement lags behinds the fuel-pump control, causing the mixture to be momentarily enriched during acceleration. Fig. 1 shows the air throttle 5 controlled from the accelerator pedal 1 by linkages 2, 3, 4 with a yielding connection provided by a spring 10, the fuel pump 8 being adjusted through an arm 24 and a rod 7 having a device 15 which contracts lengthwise under the suction of the induction pipe, to which it is connected by a pipe 16. The device 15 comprises an elastic vessel 17 connected to a container 18 through a plug 25 having a narrow orifice, the vessel 17 being filled, and the container 18 partly filled with a non-volatile liquid. A cover 19 of the container is connected to the arm 24 and has a helical extension closely fitting the container, which serves to prevent air from reaching the plug 25 during jolting of the vehicle. The narrow passage in the plug 25 acts as a dash-pot to slow down the action of the vacuum on the elastic vessel 17 in lengthening or shortening the rod 7.

Abstract: 539,492. Radio-gramophones. PHILIPS LAMPS, Ltd. March 11, 1940, No. 4565. Convention date, March 14, 1939. [Class 40 (v)] [Also in Group <SP>XXXVIII]</SP> The casing 10, Fig. 1 of a radio-gramophone is provided with a slit 14 near one side for the insertion of a sound record disc 15, which is then clamped to a vertical turntable on an horizontal axis by means of an external side knob 16, part of the disc remaining outside the casing. The knob 16 is attached to two cylindrical bushes 17, 18, Fig. 2, and is urged outwards by a spring 37. When a record disc 14 has been inserted as shown between the turntable 29 and the knob device, the knob 16 is pressed in. Inward pressure is applied through spring 20 to thimble 19 which pushes rod 22 inwards. The conical head 26 of the pin 22 seats itself in the conical recess 27 in the turntable spindle 28, and a conical collar 31 loosely mounted on the pin 22 against a spring 32 grips the periphery of the central hole 30 of the record disc and centres the disc relatively to the spindle. The pin 22 is guided in a conical collar 25 which is normally seated in a conical seat on a sleeve 23. When the spring 32 is compressed by the engagement of the conical shoulder 31 with the record and the continued inward movement of the pin 22, the loose fit between the pin and the thimble 19 and between the collar 26 and its seat allow the lateral deflection of the pin necessary to centre the record. This arrangement does not need accurate alignment of the knob 16 with the spindle 28. When the knob has been pushed in, it is turned slightly to engage a bayonet joint 36 to retain the knob in the inward position gripping the record for playing.
