Title: 3-hydroxy-3,7,11-trimethyl-4,6,10-dodecatrienoic acid and salts thereof
IPC: C07C59/42
Filed: 1958-02-19
Abstract: The invention comprises 3-hydroxy-3,7,11, trimethyl - 4,6,10 - dodecatrienoic acid, its alkali and alkaline-earth metal salts, and the preparation thereof by reacting pseudoionone with an a -haloacetate in the presence of zinc, saponifying the ester thus formed to the corresponding salt and, if desired, hydrolysing the salt to produce the free acid; additionally, if desired, the free acid is reacted with a base derived from an alkali metal to produce an alkali metal salt and again, if desired, a solution of the latter salt is reacted with a water-soluble alkaline earth metal salt to form an alkaline earth metal salt of the acid.  In examples, pseudoionone is reacted with zinc and ethyl bromoacetate to form, after decomposition of the complex, ethyl 3-hydroxy,3,7,11-trimethyl-4,6,10-dodecatrienoate which is saponified by alcoholic potash and acidified to give the free acid; the free acid is neutralized by caustic soda to give the sodium salt; and, the sodium salt treated with calcium chloride to give the calcium salt.

Patent GB-877391-A (GB)
Title: Improvements in and relating to thermoplastic resinous compositions
IPC: C08F18/08
Filed: 1960-02-17
Abstract: A thermoplastic resinous composition, capable of polymerization to a thermoset resin, comprises a partially polymerized diallylic ester of a phthalic acid, a peroxide polymerization catalyst and a fatty acid having 8-18 carbon atoms in the chain or a mixture of such fatty acids, the fatty acid or mixture thereof being present in an amount from 0,5%-5% of the ester.  The diallylic ester may be derived from allyl or methallyl alcohols and from ortho-, iso-, tere-, tetrahydro-ortho- or hexahydro-ortho-phthalic acids or from mixtures of these and the polymers may be modified by copolymerization with other allyl or vinyl compounds.  The diallylic ester is first polymerized to a low molecular weight prepolymer where the reaction is stopped by quenching, lowering the temperature or use of chain-transfer agents.  In the final polymerization the prepolymer may be mixed with, besides the peroxide catalyst and fatty acid, a monomer, e.g. further diallylic ester, filler, e.g. calcium carbonate, calcium sulphate, titanium or silicon dioxide, colorant, e.g. chromeyellow and phthalocyanin blue inhibitor or reinforcing agent.  The fatty acid may be lauric, caprylic, myristic, palmitic or coconut fatty acids.  The peroxide is preferably an organic peroxide, e.g. benzoyl peroxide, t-butyl hydroperoxide or t-butyl perbenzoate. The compositions may be used in laminating or may be moulded at 120 DEG -180 DEG C. under pressure.  In laminating applications, the resin composition is applied in solution, e.g. in methyl isobutyl ketone or acetone and dried prior to cure.  U.S.A. Specification 2,273,891 is referred to.

Abstract: 926,416. Microfilm cameras. PHOTOCOPIE G.m.b.H. Feb. 15, 1961 [March 30, 1960], No. 5602/61. Drawings to Specification. Class 98 (1). In a microfilm flow camera in which movement of the film is initiated by the document to be photographed, means are provided to maintain the film movement for a fixed time after it starts, so that irrespective of document size the resulting used area of film is the same. The film movement is maintained by the use of a switching disc or drum having a variable conducting circumferential length over which a contact moves, the time chosen being variable by adjustment of the disc or drum and/or of the contact; or the time of film movement may be controlled by a time delay relay. The switching of the means controlling film movement may be indicated by a visible and/or audible signal. As applied to cameras in which the film feed ceases on completion of the document exposure the normal cut-out provided is rendered inoperative.

Title: Electric control arrangement for motor drive system of tap changers for regulating transformers
Inventor: STENZEL KARL
IPC: H02P13/06
Filed: 1970-02-06
Abstract: 1278196 Control of AC motors E SCHEUBECK 6 Feb 1970 [27 Feb 1969] 5779/70 Heading H2J The drive motor M of the tap changer mechanism of a transformer is provided with a control system, which ensures that only one tap change is made irrespective of the duration of the control command and which comprises motor contactors Cl, C2, a brake contactor d2, a control relay d1 and two cams driven by the motor, these cams respectively actuating one microswitch b3, Fig. 2 (not shown), and a pair of microswitches b4, b5, Fig. 3 (not shown). In a typical "tap-up" operation, a press button switch b1 is closed to energize contactor Cl and brake contactor d2, so starting the motor M. Switch b3 provides a self-holding circuit until switch b4 is closed to maintain Cl energized. Further motor movement changes over b3 to energize the relay d1 which has self-holding contacts in a circuit including contacts of C1. Further motor movement restores b3 and then opens b4 to de-energize members C1, d1, d2 and so complete the tap change, all the components having returned to their original conditions. Continuous closure of the switch b1 prevents deenergization of d1 at the end of the tap change and thus the initiation of another tap change. Operation of switch b2 to tap down produces a similar sequence of events involving members C2, d2, dl. The control system also provides the following features:-(1) Automatic re-starting after a mains voltage failure during a tap change, all the relays and contactors assuming their conditions prior to failure when the voltage is restored. (2) Automatic travel over one or more dead stages if present in the tap sequence. A contact b9 corresponding to the stage(s) prevents operation of b4 or b5 to terminate the tap change, until the stage(s) is/are traversed. (3) Prevention of a tap change if the motor M is connected to a supply of incorrect phase sequence. Closure of b1 or b2 causes the motor to rotate until b4 or b5 is actuated which, with the connections of the other components, causes the motor to reverse, return to its original position and stop.

Title: Improvements in or relating to four wheel brakes for vehicles
IPC: B60T7/06
Filed: 1925-03-06
Abstract: 230,482. Siemens - Schuckertwerke Ges. March 8, 1924, [Convention date]. Brakes, arrangement and disposition of, and braking.-Application of the front wheel brakes of a motor vehicle is prevented unless the rear wheel brakes have been first applied. A sleeve 16, Fig 1, is slidably but non-rotatably mounted upon the fixed shaft 15 upon which turn the foot levers 11, 12 controlling respectively the front and rear wheel brakes. With the lever 12 in the normal position shown, lateral movement of the sleeve 16 is prevented by a projection 20 on the boss of the lever 12 and as a consequence movement of the lever 11 is prevented by engagement of a projection 19 thereon in a recess in the sleeve. When, however, the lever 12 is moved to apply the rear wheel brakes, the projection 20 comes opposite to a recess 18 in the sleeve, which can thus slide laterally to permit movement of the lever 11 to apply the front wheel brakes. In another construction, movement of the lever 12 causes a sleeve to be positively moved laterally so as to displace a projection on the sleeve from engagement with a projection on the boss of the lever 11. According to a further construction, Fig. 3, the lever 12 when moved to apply the rear wheel brakes is arranged to engage a bellcrank lever 26 and thereby to withdraw a bolt 28, which normally prevents movement of the lever 11 of the front wheel brakes.
