Title: Improvements in Circuit Breakers for Ignition Apparatus.
Filed: 1917-10-08
Abstract: 129,309. Remy Electric Co., (Assignees of Kennington, W. O.). Nov. 10, 1916, [Convention date]. Rotary interrupters, for ignition apparatus of the kind having spring-closed cam-opened contactarms, are provided with a number of breaker devices adapted to operate in predetermined order so as to reduce the effective extent of contact opening to a minimum. As shown, two contact-arms 20, 21 are pivoted on a common axis 22 and are operated alternately by cams 12, 13 mounted in opposite phase on the shaft 11. The contacts 20<a>, 21<a>, co-operating with fixed contacts 16, 17 are arranged in parallel in the primary circuit, the terminals of a condenser 15 being connected by conductors 32, 33 to the fixed and movable contacts. In operation, one set of contacts is opening while the other set is closing, both sets being open simultaneously for a short period, and one of the sets of contacts being closed at all other times. By the use of two six-pointed cams, the interrupter is adapted for the ignition of a twelvecylinder engine, each contact-arm making six vibrations per revolution of the shaft 11. Reference has been directed by the Comptroller to Specification 101,980.

Title: Improvements in or relating to contact brushes for wire wound variable resistances or rheostats and other electrical apparatus
IPC: H01C1/12
Filed: 1941-11-17
Abstract: 551,747. Variable resistances. CURTIS MANUFACTURING CO., Ltd., and CURTIS, F. C. Nov. 17, 1941, No. 14772. [Class 37] The slider contact brush comprises a metal contact brush formed with a slot in which is disposed a carbon or other self-lubricating contact member which moves with the contact brush as a whole, in a direction parallel to the contact surface,'but is also movable independently of the metal part of the brush in a direction towards and away from the contact surface. Resistance wire 1, Fig. 2, is wound on an insulating carrier and a slider 2 carrying the brush 3 is adjustable along a guide rod 4. The brush 3 is formed of a number of metal strips shown in Figs. 4; 5 and 6. The top lamination consists of a spring metal strip 5 turned over at its end 6 and having slots 7, 8 with an intermediate bridge 9, which is indented so as to be of semicircular cross-section. three intermediate laminations 10, 11, 12 are shaped as shown in Fig. 5 with the ends 13 turned over and slotted at 14. The bottom lamination 15 is shorter than the others and has its end 16 turned over. A carbon block 17 is shaped as shown in Fig. 3 with a curved contact surface conforming to the curvature of the rheostat 1, and is of a width to fit into the slots 7, 8, 14. The spring lamination 5 engages the top of the block so that the bridge 9 engages the depression 18, the parts 19, 20 project through the slots 7, 8, and the downturned end 6 engages over the end of the carbon block 17. A direct connection to the carbon block may be made through a flexible metallic cord. The contact brush may be so designed as to have a substantially constant contact resistance under varying working temperatures, since the metal laminations have a positive temperature coefficient while the carbon block has a negative coefficient. The brush may alternatively be carried at the end of a rotary arm so as to engage a resistance wound on an arcuate or part annular carrier.

Title: Improvements in or relating to colour photography
Inventor: BOSSARD WERNER
IPC: G03C7/29
Filed: 1957-05-09
Abstract: There are described yellow dyestuffs of the formula: <FORM:0841300/IV (c)/1> where X is an unsaturated aliphatic, aromatic or heterocyclic divalent radical and the benzene rings may be symmetrically substituted about X with non-ionogenic substituents or alternatively the terminal rings may each have a carboxylic or hydroxy group.  The products are used in photographic elements (see Group XX).  In general, the dyestuffs are prepared by coupling a diazotised amino benzene sulphonic acid with an amino benzene to produce a monoazo dyestuff which is acylated with an acid dichloride or dibasic acid anhydride.  In the first group of examples the amino sulphonic acid or the methyl, dimethyl, methoxy, chloro or hydroxy carboxylic acid substituted amino sulphonic acid is diazotised and coupled with methyl, methoxy, methoxy-methyl, acetylamino or carbomethoxyamino amino benzene and the monoazo dyestuff thus obtained is reacted with benzene 1,3 or 1,4 dicarboxylic acid dichloride or benzene 2,5 dichloro 1,4 dicarboxylic acid dichloride. In a second group of examples, monoazo dyestuffs of the first group are reacted with a pyridine, thiophene furan or pyrrole dicarboxylic acid dichloride. In a third group of examples monoazo dyestuffs of the first group are reacted with fumaric or methyl, bromo or chloro fumaric or butadiene 1,4 dicarboxylic, maleic or methyl maleic acid dichloride.  In a fourth group of examples the amino sulphonic acid or the methoxy ethoxy or hydroxy carboxylic acid substituted amino sulphonic acid is diazotised and coupled with methoxy-methyl or acetylamino amino benzene and the monoazo dyestuff thus obtained is reacted with benzene 1,4 or pyridine 1,5 dicarboxylic acid dichloride.

A low-speed drive for a roller 22, as used on a rolling mill table, is obtained by coupling two separate induction machine stator windings 11, 13 of differing pole numbers to a supply, the rotors 15, 16 being coupled mechanically, and the stator 13 being free to rotate and coupled to the roller. Either machine can be wound for the lower or higher number of poles and the connections are arranged so that the roller speed is the difference between the two machine speeds. Either or both machines can be arranged for pole changing for different speeds, or reversal. The machine 13, 16 may be accommodated within the roller 22. As a small change in the slip of either machine will bring the combination to a standstill, stalling will. not cause serious overload of either stator winding. The housings of both machines can be arranged not to exceed the diameter of the roller.

Title: Improvements relating to cyclic adsorptive separation processes
Inventor: TURNBULL JOHN NEIL
IPC: B01D53/047
Filed: 1966-04-06
Abstract: In a cyclic vapour phase adsorption-desorption separation process using a fixed bed of solid selective adsorbent, the desorption is effected by forming a partial vacuum on the adsorption bed by directly condensing, with a quench liquid, the affluent vapours from the bed during the desorptive step.  A purge step may be interposed between adsorption and desorption which is also effected by forming a partial vacuum by condensation of effluent from the purge step wherein the pressure is reduced to a level intermediate the adsorption and desorption stage pressures.  The process is particularly suitable for separation of n-hydrocarbons from iso- and cyclo-hydrocarbons by application to the process of Specification 1,026,116.  The selective adsorbent may be molecular seive.
