Title: Improvements in or relating to measuring instruments
IPC: G01P3/495
Filed: 1932-07-28
Abstract: 389,001. Damping vibrations. ETABLISSEMENTS E. JAEGER, 2, Rue Baudin, Levallois-Perret, Seine, France. July 28, 1932, No. 21319. Convention date, April 25. [Class 108 (iii).] A spiral spring has its outer turn 14 curved so as to pass across the spring close to its axis. The spring is used as a combined damping and restoring spring for a measuring instrument. The inner end 7 of the spring is attached to the spindle 2 which carries the instrument pointer, while the outer end is secured to a fixed post 8. The turn 14 of the spring thus acts on the spindle 2 to provide a damping force which increases with the deflection of the instrument pointer.

Title: Means for cleansing empty oil or like bottles
IPC: B08B9/34
Filed: 1952-08-26
Abstract: 717,299. Cleaning bottles. EVANS, R. R. June 29, 1953 [Aug. 26, 1952], No. 21381/52. Class 138 (1) Means for cleansing empty oil and like bottles when a source of compressed air is available include a main, open-topped container 11 for a cleansing liquid 12 (e.g. paraffin or petrol), a closed container 15 therein, having a stand pipe 16 which extends down to near the bottom of the container 15 and the upper end 17 of which terminates in a spray nozzle or the like (not shown) to extend into an inserted bottle 35 when placed thereover, and valve means for placing the lower end of the container 15 in communication with the liquid 12 and for placing the upper end of the container 15 in communication with the compressed air whereby, when the container 15 is charged but no longer in communication with the liquid in the container 11, the liquid in the container 15 will be sprayed from the nozzle to fall back into the container 11 for re-use. When the apparatus is inoperative a combined lever 20 and abutment 34 pivoted at 25 in a fixed bracket 24, is urged by a spring 21 to open the valve 18, biased in the opposite direction by a spring 19, to allow liquid to pass through passages 22 to the interior of the container 15. At the same time a cam 26 of the lever co-operating with the spring-urged movable member 27 of a known type of air valve 28 is so positioned as to allow the valve to close-off the supply of compressed air delivered to the valve through a known connection 31. The upper end of the container 15 at this time, is vented to atmosphere through a pipe 23 connected to the air valve. When a bottle 35 is applied to the nozzle on the upper end of the extension 17 of the pipe 16, the abutment 34 is depressed whereby the valve 18 is closed by the spring 19 against the bias of the spring 21, and the air valve 28 is opened by the cam 26, the atmospheric vent then being closed. After the liquid in the container 15 has been ejected through the nozzle by the compressed air, air alone will be supplied to the nozzle to remove liquid from the interior of the bottle. When the bottle is removed, the container 15 will be recharged with liquid in readiness for a further cleansing operation. Specification 670,136, [Group XIV], is referred to.

Title: A semiconductor device
IPC: H01L23/48
Filed: 1966-05-13
Abstract: 1,110,267. Semi-conductor devices. SIEMENS - SCHUCKERTWERKE A.G. 13 May, 1966 [5 June, 1965], No. 21492/66. Heading H1K. A semi-conductor device 5 in an air-tight housing is held by spring or like resilient means 18 between two terminals (one of which may be a part of the housing) and the spring or equivalent acts between a support carried by an insulated housing part 8 and one of the terminals. As shown, one terminal is the housing base 1 and the other is the connector 6. The spring is a stack of separate spring members surrounding the connector 6 and located between rings 19, 20 one of which rests on the enlarged head 7 of the connector 6 while the other engages a support 17 carried by the insulated housing portion 8. Although the support 17 is shown as a ledge cut into the portion 8, it is in fact constituted by a separate support member which is secured, e.g. by brazing, to the interior of the portion 8. The insulated housing portion 8 fits in a groove 3 in the base 1 and is surmounted by a metal cap 9 carrying a tube which accommodates the connector 6 and the external lead associated with it. The housing is sealed by brazing the portion 8 both to this cap 9 and to a metal ring 10 fixed on the base. The labyrinthine path from the exterior to the interior of the housing around the ring 10 and the lower end of the portion 8 prevents contaminants entering the housing during the sealing process.

Title: Electric remote control system
IPC: B61L7/06
Filed: 1960-06-21
Abstract: 893,420. Control of A.C. motors. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. June 21, 1960 [July 31, 1959], No. 21664/60. Addition to 866,175. Class 38 (3). [Also in Group XXX] The two-phase motor control system for railway switch points described in the parent Specification is modified so that the centre point, instead of one end, of each phase is earthed, thereby increasing the safety of the equipment in relation to the phase voltage. The supply is connected to terminals P1a P1b and P2a, P2b, across which are auto transformers I and II, whose centre points are connected to the earthed neutral N. Consequently, it is now the centres of the windings M1, M2 of the motor M which are interconnected by switches N and R during changeover. Reversal of the motor is now achieved by reversing the connections to winding M1 by contacts G3, G4 while keeping those to M2 unchanged. As shown, supervisory current from S reaches rectifier V, via L4 and half of M2, where alternate half-waves are blocked and so return to earth through a circuit which includes the other half of M2, the whole of M1, leads LI ... L3 relay coil H and indicating relay NR, operation of which indicates continuity. Change-over of the points is effected by the energization of relays E, F and G, when the windings M1, M2 are connected to respective phases of the supply and supervisory current is cut off, so isolating the indicating relays NR, RR by the consequent opening of contacts H1. A polarized relay B3, energized in the appropriate direction when the driven element T operates switch R at the end of its travel, de-energizes relays E, F, G to restore the circuits to the inactive state shown and receives its supply from a transformer B5. One side UV of this transformer has opposed half-windings to cancel voltages induced from the other side XY which is across phase II, but a voltage from P1 and neutral, applied to UV, induces a voltage at O relative to X and Y so that current for relay B3 flows from O back to X and Y through a circuit which includes the two halves of transformer I and the rectifier V. An alternative path through transformer II is blocked by choke B4; this is double wound so that it does not impede the motor current which flows in opposite directions in each half.

Title: Organic phosphine oxides and method of preparing same
IPC: C22B3/38
Filed: 1960-06-22
Abstract: The invention comprises primary organophosphine oxides having the formula:-RP(O)H2 wherein R is a substituted or unsubstituted alkyl, alkenyl, cycloalkyl, aralkyl, alkaryl, or aryl group, the radical R when alkyl being branched or straight chain.  They may be obtained by treating a primary phosphine RPH2 with hydrogen peroxide, an organic hydroperoxide or peroxide, or dinitrogen tetroxide, in an inert atmosphere, e.g. of nitrogen or carbon dioxide.  Specified substituents which may be present are nitrile, alkoxy, halogen, hydroxy and carbalkoxy. The reaction is advantageously carried out in an inert organic solvent medium such as a monohydric alcohol, chloroform, ether, ethyl acetate, hexane or benzene.  Specified primary phosphine starting materials are phenyl-, p-methyl phenyl-, cyclohexyl-, dodecyl-, n-octyl-, isopropyl, allyl-, 2-hydroxyethyl-, 2-cyanoethyl-, benzyl, p-chlorophenyl-, benzyl-, methyl-, isobutyl-, and 2 - carboethoxyethyl - phosphine.  Specified oxidising agents are hydrogen peroxide, tertiary-butyl hydroperoxide, dinitrogen tetroxide and benzoyl peroxide.  The reaction may be effected at between -50 DEG  and 60 DEG C. and preferably at between -10 DEG  and 20 DEG C. and atmospheric or higher or lower pressures may be employed.  The process may be carried out batchwise, continuously, or semi-continuously, and the oxidising agent is preferably introduced into the phosphine reactant.  The products are useful as sequestering agents for selectively removing metal ions from mixtures containing them, e.g. uranyl values can be selectively leached from mineral ores containing such values.
