Title: An improved arrangement for protecting a thermionic valve against excessive current
IPC: H01J19/82
Filed: 1945-05-07
Abstract: 591,385. Valve circuits. BRITISH INSULATED CABLES, Ltd.:, QUAYLE, J.C., and JONES, P. May 7, 1945, No. 11557. [Class 40 (v)] An arrangement for protecting a thermionic valve against excess current comprises a shunted self-restoring relay in the anodecathode circuit which when operated by excessive current increases negative bias in the grid circuit and removes the shunt from the relay winding. In the Figure, an oscillator circuit for radio frequency heating, is shown as an example incorporating the arrangement. When relay RL, shunted .by resistance R2, operates from excessive anode current, the contact RLC1. opens and connects the relay coil and its shunt in series with the grid bias resistance R1, so increasing the negative grid bias. The simultaneous removal of the shunt R2 renders the relay more sensitive so that it is retained until the anode current falls below a certain small amount. Resistance R3 is a permanent shunt to adjust operating conditions for the particular relay.

Title: Improvements in the production of polymeric materials
IPC: C08G73/08
Filed: 1945-05-10
Abstract: Fibre-forming polymers containing 4-amino-1.2.4-triazole rings are made by (1) heating a dicarboxylic acid dihydrazide in presence of hydrazine until a polymer is produced, or (2) heating a dicarboxylic diester with more than two molecular proportions of hydrazine until a polymer is produced.  The excess of hydrazine, combined and uncombined, over two mols. may amount to 10 per cent of the total reagents, and up to one mol. thereof may be replaced by the hydrazide of a monobasic acid.  Water may be present during the reaction which may be carried out at temperatures of 200-300 DEG  C., preferably 230-280 DEG  C., in a closed vessel under superatmospheric pressure, though the pressure may be reduced below atmospheric towards the end of the reaction.  Dicarboxylic acids specified are succinic, glutaric, adipic, pimelic, suberic, azelaic, sebacic, diphenic, phenylene-1.4-diacetic, diglycollic, N-methylimino-diacetic, esters specified are the methyl, ethyl and phenyl esters, and monobasic acid hydrazides specified are acetyl and lauryl hydrazides.  The viscosity of the polymer may be stabilized by hydrolysing the terminal hydrazide groups, e.g. with hydrochloric or other mineral acid.  The polymers are soluble in phenols, cresols and xylenol.  The polymers may be made into filaments by melt-spinning at 10-30 DEG  C. above the melting-point of the polymer, mixed with sulphonamide, phenolic, urea and thiourea plasticizers, or by wet or dry spinning from solutions in formic or acetic acids.  The filaments may be cold-drawn.  The polymers may be used for softening or coating and may be mixed with plasticizers, softening agents, dyestuffs, or pigments.  In examples, sebacic dihydrazide is heated with (1) acetic hydrazide, and (2), (3) and (4) with different amounts of hydrazine hydrate; in (5) suberic dihydrazide is heated with hydrazine hydrate, and in (6) the polymer formed in (3) is dissolved in o-phenylphenol and m-cresol, the m-cresol boiled off and the residue melted and spun.

Title: Improvements in filing cabinets
IPC: G06K17/00
Filed: 1942-08-31
Abstract: 559,255. Filing papers. NICHOLSON, J. N. Aug. 31, 1942, No. 12239. [Class 146 (i)] In a card-index filing-cabinet of the kind comprising trays 18, Fig. 1, mounted on one or more endless conveyers and adapted to receive cards stacked on edge, the conveyers, which are driven by an electromotor, are arrested by automatic selectormechanism controlled by press-buttons, in order to present any tray at an opening 19 in the cabinet for inspection or removal of the cards, the selection being effected by stoppage of the motor. Each conveyer comprises two chains 12 passing over sprockets 13, one pair of which is driven by a motor 15. The trays are removably secured to the chains by slotted brackets 22, Fig. 7, which engage pins on triangular plates 20 attached to the chains. The trays have wheels 28 running on fixed rails. When the trays are on the bottom run of the conveyer, the cards are retained by a pair of rods 77, Fig. 8, which engage T-shaped slots therein. At the inspection position the rods 77 are moved together by tonglevers 75, 76, which are operated by stationary rails 84. In an arrangement comprising two conveyers, each of which carries twenty trays and is driven by a separate motor, the selector-mechanism is operated from a dial 31, Fig. 1, of pressbuttons comprising four Tens and ten Units buttons. Depression of a button in each set starts one of the motors, which is automatically arrested when the selected tray is in position. Numbered rotatable rings 36 indicate the selected trays. The motor circuits are controlled by two distributerdiscs 39, Fig. 9, corresponding to the two conveyers and bearing outer and inner rings of contact-studs 40, 41, over which move two switch-arms 44a, 44b geared to the motors. The press-buttons 57, 58 serve to make the circuits of four Tens relays 43 and ten Units relays 45, which receive current from a transformer 61. Each of the Tens relays is connected to a group of ten inner studs 41 on the distributerdiscs, and each Units relay is connected to four individual studs 40 of the outer series. When a Tens and a Units button are depressed simultaneously, a circuit is completed through the two associated relays. The armatures of the relays close the switches 47, 55 of holding-circuits, which cause the relays to remain energized when the buttons are released. The Tens relay also closes a switch 68 in the circuit of one of the motors, and the corresponding switcharm rotates until it bridges the designated pair of contact-studs. A path of lower resistance is thereby completed through a coil 71, so that the relays are de-energized and the motor stops. The motor may be braked to ensure prompt stopping.
