Title: Improvements in electric switches
IPC: H01H13/60
Filed: 1920-11-15
Abstract: 155,813. Essen, A. von, (Assignee of Wahlstrom, R.). Dec. 23, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Switches, quickaction; handles.- Quick-action mechanism for a press-button switch comprises a guideway 10 secured to the base and serving to guide a rectangular contact-member 9<a> which carries the contact 23 for bridging engagement with fixed contacts and is recessed, centrally, to accommodate a doublearmed spring 19 one arm or other of which is compressed by a spring tongue 22 on the operating button to produce a quick action at the completion of the operating stroke. The closed position of the switch is shown in Fig. 3, the fixed clip contacts not being shown. To open the switch, the button 11 fixed on the end of a pair of parallel rods 13 moving in grooves in the guide 9<a> is depressed against the action of springs surrounding the rods; the spring plate 22 secured to the press-button engages the right-hand inclined channel 20 in the contact member and compresses the right-hand arm of the spring 19. The contact-member is locked against movement, however, until the inturned ends 14 of the rods are pressed out of a recess 16 in the contact-member, which takes place only when the button is fully depressed. The switching-on movement is similar, a second depression causing the plate spring 22 to ride down the other channel 21 and compress the other arm of the spring until, finally, the inturned ends of the rods are removed from channels 15 into which they passed to lock the switch in the off position. By providing contacts at both ends of the contact-member, a change-over switch is produced. The pressbutton may be enlarged to constitute a cover for the switch.

Title: A new or improved method for producing hydrogen and apparatus for carrying out the said method
Inventor: GREGORY SYDNEY ABSELL
IPC: C01B3/04
Filed: 1959-09-25
Abstract: In a method of producing hydrogen in which ammonia is vaporized and then dissociated into a H2/N2 mixture, the mixture is passed through at least one bed of a "molecular sieve" which is capable, when maintained at a predetermined temperature within the range - 20 to - 100 DEG C. of adsorbing N2 whilst letting through the H2, the bed being cooled to and -maintained at the predetermined temperature by vaporizing ammonia.  Nitrogen may be produced as a by-product by saturating the bed of molecular sieve with nitrogen at the predetermined temperature and thereafter allowing or causing the temperature of the bed to rise to a value at which the nitrogen is released by the bed. Preferably the gases are made using a three-bed system such that at any given time during continuous operation, one bed is being saturated with N2, another bed is being purged of adsorbed N2 and a further bed is being pre-cooled in preparation for N2 adsorption.

An earth leakage protective system comprises an impedance 17, 18 and an A.C. source 20, 15, having a frequency which is relatively high with respect to the mains frequency, connected between earth 19 and an artificial neutral point 11 provided by inductors 12 star-connected to the phase conductors ] 3. The point 11 is also connected to earth 14 through a capacitor 13 so that under normal conditions the H.F. current flows in the circuit 14... 19 and biases a transistor 22 so that it produces a highfrequency output which is amplified at 23. transformed at 24, rectified at 28 and energizes a relay 27 which at contacts 29 completes the energizing circuit of a contactor 4, 5. In the event of an earth fault, current of mains frequency flowing to earth through the impedance 17, 18 causes the transistor 22 to be altemately cut-off and overdriven so suppressing the H.F component from the output of the transistor 22. The transformer 24 presents a lower impedance to the mains frequency current and relay 27 releases causing the contactor to open.

Abstract: 363,463. Current transformers. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 31, 1930, No. 32779. Convention date, Oct. 31, 1929. [Class 38 (ii).] Relates to a method of producing current transformers conforming to desired limits of accuracy in conditions in which the available core material varies considerably in permeability, and consists in designing a transformer on the assumption that all the core laminations have the lowest value of permeability likely to be met with in the material available, then building up a core with an average number of laminations, subjecting it to a test and adjusting the number of laminations in accordance with the test result, thus arriving at a core cross section which will, with standard windings, produce a transformer capable of working within the desired limits of accuracy. To facilitate testing in the case of transformers with closed ring cores, a divided auxiliary winding is employed. Spaces due to the available core cross section not being completely occupied by laminations are filled with non- magnetic material such as presspan, wood, &c.

Title: Improved graft polymerization process
IPC: C08F279/02
Filed: 1964-08-13
Abstract: A graft polymerization process comprises prepolymerizing with agitation a feed mixture comprising a monovinyl aromatic compound and a synthetic or natural rubber dissolved therein until substantially all of the rubber phase is out of solution and the rubber particles have an average size of less than 10 microns, and then subjecting the resulting reaction product mixture to further polymerization to obtain a higher level of conversion to polymeric material.  Monovinyl aromatic compounds specified are styrene, a -methyl styrene, vinyl toluene, vinyl xylene, vinyl ethyl benzene, vinyl chlorobenzene, and mixtures thereof.  The rubber is dissolved in the monovinyl aromatic compound and prepolymerized in bulk using heat or oil-soluble organic peroxides as reaction initiators. The prepolymerized mixture is then either suspended in an aqueous solution containing a suspending agent such as hydroxyethyl cellulose and further polymerized with the addition of an organic peroxide catalyst, or suspended in an inert organic solvent such as ethyl benzene and further polymerized at a higher temperature. A number of other suspending agents and solvents are listed.  The usual additives such as lubricants, antioxidants, chain regulators and inert fillers may be incorporated in the prepolymerization reaction mixture.  The prepolymerization is effected under high shear conditions.
