Title: Improvements in or relating to exothermic mixtures
Inventor: ANDREW ALFRED TRESHAM
IPC: B22D27/06
Filed: 1958-09-24
Abstract: An exothermic composition is produced by mixing finely divided aluminium, magnesium or alloys of either with a substantially stoichiometric amount of oxidising agent and a binder, granulating the product to size not less than 200 B.S. mesh and thereafter adding a further amount of aluminium &c. and a refractory filler.  Other ingredients, e.g. fluorides, may be added before the granulating step and the aluminium may be in the form of ball mill dust.

Patent GB-619077-A (GB)
Title: Electrical control system
IPC: H04Q1/18
Filed: 1946-10-18
Abstract: 619,077. Electric correspondence control. STANDARD TELEPHONES & CABLES, Ltd. Oct. 18, 1946, No. 31054. Convention date, Nov. 3, 1945. [Class 40 (i)] [Also in Group XXXIX] An electrical control system comprises a brush engaging successively a plurality of contacts at different potentials, and means for applying a firing potential to the electrode of a gas tube when the brush engages a contact with a potential of predetermined value, and means for preventing the firing of the gas tube except when that contact is engaged, including a condenser between the firing electrode and earth. As shown, a register wiper RB and a selector wiper T each connect one of a number of potentials to a rectifier bridge network S1-S4, the positive output of which feeds the grid and the negative the cathode of a tube V. While the potentials differ, the tube conducts, but when the potentials match, the output of the bridge is nil and the tube cuts off, raising the potential of the control grid of a gas-filled tube GV to firing point to energize a relay GVR which cuts the circuit to the usual clutch magnet P to halt the selector wiper. To prevent firing of the gas tube due to momentary accidental matching while the selector wiper is passing from one terminal to another, the control grid and cathode of the gas tube are connected by a condenser C and resistance R7 which impose a slight delay on the response of the gas tube. Specifications 579,011, [Group XXXIX], and 592,846 are referred to.
Patent GB-393185-A (GB)
Title: Improvements in cop winding machines
IPC: B65H63/02
Filed: 1932-11-04
Abstract: 393,185. Winding-machines. LAMBERT, O., 6, Cauwerberg, Tamise, Belgium. Nov. 4, 1932, No. 31107. [Class 120 (ii).] In a cop-winding machine of the type in which the spindle is rotatable with and slides through a sleeve driven by a clutch controlled by a stop-motion, actuated upon completion of winding or yarn breakage, the clutch comprises a circumferentially expansible and contractible member. The spindle 1 carrying the cone 30 is slidably mounted in the sleeve 2 which carries a friction clutch member 10. The driving wheel 5 rotates the pinion 4, freely mounted on the sleeve 2. Slidably mounted on the hub of the pinion 4 is a collar 46 carrying a pin 12, which enters a graduated slot in the expansible clutch member 11, and transmits the drive to the clutch member 10 when the clutch assembly 6, 46, 12 is moved to the right by the rod 7. The clutch-operating rod 7 is urged to the left by the spring 9, but is held in the clutched position by an arm 15 on the rod being held by a catch 44. When winding is completed, the spindle 1 has moved axially in the guide tube 16 until the projection 18 engages the lever 23, thereby slightly rotating the rod 7, which frees the arm 15 from the catch 44 and allows the spring 9 to effect declutching. The drive is also disconnected if the yarn Y breaks and allows the pulley 52 to drop, whereby the finger 56 actuates a tappet which moves the arm 15 free from the catch 44. The spindle is restarted by moving the handle 13, which is pivoted at 13a and connected to the rod 7 at 50, to the right. The traverse rod 27, carrying a thread guide 29 which rests on the cone 30, is reciprocated by an eccentric 36 mounted on an eccentric ring 35 secured to the shaft 34. The driving wheels are rotated by pins 57 engaging in slots 58 in the eccentrics 36. The eccentricity of the latter is adjustable, for varying the traverse, by altering the relation between the eccentric 36 and the eccentric ring 35. To facilitate this adjustment, screws 38 in the collars 37 are engaged by box spanners 39 and loosened, the shaft 34 is then rotated the desired amount, carrying with it the eccentric rings 35, but not the eccentrics 36 which are held by the pins 57 on the members 5a, the latter being in engagement with the collars 37 and so prevented from rotating by the box spanners 39. The screws 38 are then tightened. The spindles 1, Fig. 5, are preferably driven in pairs, each pair having a common traverse rod 27. The driving and traverse mechanism is housed in an oil-box 14.

Two gaseous discharge devices, e.g. fluorescent lamps 24, 25, are connected to a starting and operating transformer 10 or 10<SP>1</SP> which comprises an elongated shell-type magnetic iron core 14, 15 which forms a single magnetic circuit, a primary winding 11 connected across an A.C. source 31 of voltage insufficient to ignite either device, and first and second secondary windings 12, 13 magnetically coupled to the primary winding and series connected end to end in the order stated with the first secondary winding 12 connected between the other two windings 11, 13, the second secondary winding 13 being mounted at one end of the core, the primary winding 11 at the centre of the core, and the first secondary winding 12 at the other end of the core and spaced, e.g. with the interposition of shunts 16 and air gaps 17, from the other two windings to give it a very high leakage reactance; the first device is connected across at least the first secondary winding 12 but not the second secondary winding 13, the second device is connected across at least both the secondary windings 12, 13, which latter are connected in voltage opposition at open circuit, and the first secondary winding 12 provides a high initial voltage to start the first device whereafter it provides a component in phase with the second secondary winding 13 to start the second device, and presents a high impedance during running to force the major flow of current through the series circuit of the two devices and the second secondary winding 13. Alternatively to the lamp connections shown, the first lamp may be connected across only the first secondary winding and the second lamp across all three windings, and in both cases a condenser 26 may be serially connected with the first device to correct the P.F. and to assist the voltage phase shift of the first secondary winding.

Abstract: 262,818. I. G. Farbenindustrie Akt.- Ges. Dec. 14, 1925, [Convention date]. Plastic compositions containing cellulose esters, ethers, &c.-Lacquers, and the like are made by adding to urea formaldehyde condensation products, preferably in an organic solvent, one or more non-volatile or difficultly volatile substances capable of forming solid solutions with the condensation products, in amounts equal to or greater than the condensaton product. Suitable substances are cellulose esters or ethers, with or without plasticizing or softening agents and natural or artificial resins. Solvents specified include methanol, diohlorhydrin, formamide, ethers of glycol, lactic acid esters. When insoluble colouring matters are added, they should be very finely ground to prevent them from separating out. According to an example, 10 parts of a 50 per cent solution of a condensation product of urea formaldehyde in methanol are dissolved in 40 parts of a 20 per cent solution of collodion; 20 parts of ethylene glycol mono-ethyl ether, 24 parts of cyclohexanol, 8 parts of butyl alcohol, and 8 parts of propyl alcohol are added to produce a glossy lacquer. The Specification as open to inspection under Sect. 91 (3) (a) includes also the manufacture of plastic masses. This subject-matter does not appear in the Specification as accepted .
