Title: Photoelectric Detector
IPC: H01J40/16
Filed: 1967-05-26
Abstract: 1,183,255. Photo-electric detectors. INTERNATIONAL STANDARD ELECTRIC CORP. 26 May, 1967 [2 June, 1966], No. 24577/67. Heading H1D. A photo-electric detector comprises an elongated member 1 of radiation transmissive material with concave internally reflective end 4 which may be a silvered mirror, and hollow elongated anode 5 with internal, reflective surface 6. Rod 1 and anode 5, e.g. of glass and silver respectively, may be hermetically sealed together by ceramic rings 7 and 8 to provide a tubular evacuated space 9. A radiation transmissive coating 3 of photo-electronemissive material on the outer surface of member 1 which may be cylindrical may be upon an electrically conductive coating of stannous oxide for applying an accelerating field between anode and cathode. The arrangement is such that radiation (visible or other light) is repeatedly reflected between the inner and outer surfaces of member 1 and anode 5 causing corresponding repetitive excitation of the electron-emissive material. Anode 5 and cathode 3 may be closely spaced to minimize electron transit times. A series of these devices may be arranged in parallel arrays.

Title: Organic phosphoric acid triamides
Inventor: MEYER FRIEDRICH
IPC: C07F9/6558
Filed: 1956-08-10
Abstract: Compounds of the formula <FORM:0808638/IV (a)/1> wherein the radical <FORM:0808638/IV (a)/2> is a dialkylamino, alkylarylamino, diarylamino, pyrrolidino, hexamethyleneimino, morpholino, or piperidino radical, and X is oxygen or sulphur (see Group IV (b)) may be polymerized to form new plastics.ALSO:The invention comprises compounds of the formula <FORM:0808638/IV (b)/1> wherein the radical <FORM:0808638/IV (b)/2> is a dialkylamino, alkyl-aryl-amino, diarylamino, pyrrolidino, hexamethyleneimino-, morpholino or piperidino radical, and X is oxygen or sulphur.  They may be obtained by reacting in the presence of an acid binding agent a compound of the formula <FORM:0808638/IV (b)/3> with ethyleneimine, the radical <FORM:0808638/IV (b)/4> and X being as defined above and Hal being chlorine or bromine. The reaction may be carried out in an inert solvent, e.g. benzene, ligroin, petroleum ether, carbon tetrachloride, ether, or dioxane, and suitable acid binding agents are tertiary amines, e.g. triethylamine, dimethylaniline, and pyridine, also ammonia or primary or secondary amines.  The amines may serve simultaneously as solvents.  Some of the halogeno phosphorus compounds may also be reacted in an aqueous or alcoholic medium in which case alkali metal hydroxides or carbonates may be used as acid binding agents. If the reaction is carried out in aqueous solution the product is preferably recovered from the aqueous medium by extraction with an organic solvent.  Examples are given for the production of (1) N-dimethylene-N1,N1,N11,N11-tetraethyl phosphoric triamide; (2) N-dimethylene-N1,N11-bis - pentamethylene - phosphoric triamide; (3) N - dimethylene - N1 - pentamethylene - N11-3 - oxapentamethylenephosphoric triamide; (4) N - dimethylene - N1,N1,N11,N11 - tetramethylthiophosphoric triamide; and (5) N-dimethylene - N1,N11 - di - 3 - oxapentamethylene phosphoric triamide.  The phosphoric acid derivatives dissolve or mix easily with water and hydroxylated solvents and with the usual organic solvents but the thiophosphoric derivatives are generally miscible only with hydrocarbons, ethers and dimethylformamide. The products may be used for treating textile materials, as therapeutic agents since they show the capacity to prevent the growth of malignant tumours in animals and may also be polymerized to yield new plastics.

Title: Moulding press
IPC: B27N5/02
Filed: 1971-04-19
Abstract: 1347745 Moulding wooden boxes SOC ANON D'EXPLOITATION DES ETABS E BOFFET 19 April 1971 [16 March 1970] 24637/71 Heading B5A [Also in Division B8] A box 1 (Fig. 12) is made of agglomerated wood in a press having more than two plungers, part of the mould cavity being formed by a carrier A1 (Fig. 2) removable from the press with the box after moulding. The box for storing fruit comprises planar side walls 3 (Fig. 12), corrugated side walls 4 and a contoured base 2; the corrugations provide rigidity for stacking. As described, wood chips or shavings and binder resins 9 (Fig. 2) from a hopper 8 are pushed into the moulding cavity B by movement to the left of a plunger 12. A plunger 35 slidable inside the carrier A1 is moved to the right by the driving rod 36 of a double acting jack, to compress the material 9 against an opposing contoured plunger 16. Simultaneously, plungers 23, 24 and (19), (20) (Fig. 8, not reproduced) are moved vertically and horizontally respectively to force moulding material 9 around the plunger 35, and to compress and shape the box walls (see Figs. 5, 8, not reproduced). Plungers 35 and 16 are then moved to the left to transfer the box into the carrier A1, and shape the upper surfaces of the box walls against a contoured sleeve 34 (see Figs. 6, 7, not reproduced). Trunnions 37 (Fig. 9) on the carrier A1 are engaged by hooks 38, and the carrier A1 and box 1 lifted from the press and transferred to a contoured conveyer 39, the carrier A1 being rotated to place the box base down on the conveyer 39. Simultaneously, feet 5 projecting from the box parallel to the side walls are turned horizontally (as in Fig. 9) by the weight of the plunger 35 and carrier A1. The carrier A1 is held in position on the conveyer 39 by latches 45, until an unloading position is reached, where the latches 45 are moved laterally, and the carrier A1 raised by the hooks 38. The plunger 35 remains stationary to hold the box on the conveyer (see Fig. 10, not reproduced), until attached pins 42 co-operate with notches 43 in carrier A1, whereupon the plunger 35 is raised with the carrier. The box is meanwhile held on the conveyer 39 by stops (44) (Fig. 11, not reproduced) engaging the upper surfaces of the box walls.

Title: Improvements in systems of reception for modulated wave telegraphy and telephony
IPC: H04B1/30
Filed: 1930-08-18
Abstract: 357,345. Valve amplifying circuits. ROBINSON, E. Y., Garvary, Dryden Road, Bush Hill Park, Enfield, Middlesex, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Aug. 18, 1930, No. 24708. [Class 40 (v).] In a receiver of the type described in Specification 201,591, [Class 40 (v), Wireless signalling &c.], in which the carrier and sidebands are separately amplified the sideband amplifier comprises a number of flatly-tuned circuits with a ganged tuning control mechanically coupled to the tuning condenser of the carrier wave amplifier. The Figure shows a high frequency amplifier A, B, C, which is flatly tuned and amplifies both carrier and sidebands, the output being applied through variometer 12 to detector valves E, F, in push-pull. The carrier is also amplified by valve D the output circuit 15 of which is oscillating feebly or is of very low decrement due to the back-coupled valve G. This carrier oscillation is applied to valves E, F in parallel and causes demodulation while the effects of the demodulation produced by the carrier applied through valve C is cancelled out in transformer 17. The sideband amplifier may be tuned by variometers or by a filter type coupling to obtain broad tuning. If the circuit 15 is oscillating feebly a heterodyne whistle is produced which on completing the tuning disappears since the local oscillation, if feeble, will be locked into phase with the carrier. To obtain a smooth reaction control free of " backlash " a resistance condenser combination 18, 19 may be employed. In a modification control of oscillation is effected by a variable shunt resistance to the tuned circuit 15 and the carrier oscillation is applied to additional grids in the detector valves. The oscillator may have a grid condenser and an adjustable leak to obviate " backlash " and in addition the filament temperature may be controlled.
