Title: Improvements in or relating to looms operating with two weft threads
IPC: D03J5/06
Filed: 1924-10-21
Abstract: 236,149. Carriol, L., and Mullor, A. June 28, 1924, [Convention date]. W e f t inserters not carrying bobbins, cops, and the like; looms with -A shuttle for use with two weft threads has at each end a steel point 2 notched at 4 and axially perforated for a thread-locking bolt 6. The bolts 6 are secured to the ends of a U-spring 7 and are retracted when the curved middle part 11 of the spring contacts with a roller 19 and is in consequence straightened. The roller 19 and a second roller 18 are carried by a spring-controlled lever 17 pivoted on the breast beam 14 in such a position that, on the beat-up, the roller 19 enters a recess 10 in the shuttle and the roller 18 engages an adjustable cam 23 on the side of the shuttle box. The shuttle is thus first moved to bring the weft to the selvedge, and when the roller 18 reaches the end of the cam 23 the roller 19 enters farther into the recess 10 and straightens the U-spring 7 to retract the bolts 6, thus allowing the shot weft to slip out of the notch at one end of the shuttle and the weft at the other end to slip in, ready to be locked. The weft 25 passes through a hole 27 in one side of the shuttle box diagonally across the box ready to be caught by the notched point of the shuttle.

Title: Improvements in electrical signalling systems
IPC: H02J13/00
Filed: 1939-09-07
Abstract: 532,514. Selective signalling. GENERAL ELECTRIC CO., Ltd., and SCOWCROFT, J. Sept. 7, 1939, No. 25236. [Class 40 (i)] [Also in Group XXXIX] A power sub-station is connected to a telephone exchange by a two-party line, and ringing over one leg initiates the sending back of supervisory signals, while ringing over the other leg operates the telephone bell. Ringing current over the positive wire energizes relay L, which starts the rotation of a switch S under the control of cyclically-operating relays X, Y, Z. Relay AR pulls up at the first step and loops the line, thus tripping the ringing. Relay HL operates over the positive wire and holds AR. The supervisory signals consist of trains of one, two, three &c. impulses, corresponding to the numbers of the circuit-breakers, of high or low tone current according to their positions. The signals are sent during successive rotations of the switch S, relay SA operating in position 6 to start the impulse train and SZ operating in a position determined by a sequence switch SS to terminate the train. The switch SS, which advances one step after each signal, brings a relay OP under the control of the circuitbreakers A-K in succession to connect high or low tone to the impulsing circuit. The signals are repeated until the calling party hangs up, when the relapse of HL restores the circuits to normal. In another arrangement, the rotation of a switch sends three trains of impulses of tone current to indicate the position of a voltageregulator.

Title: Improvements in or relating to preparation of benzylmalononitrile
IPC: C07C255/32
Filed: 1954-09-01
Abstract: Benzylmalonitrile is prepared by a process which comprises reacting benzene with 1,1-dicyanoethylene in the presence of an aluminium halide catalyst.  The reaction is preferably carried out in the presence of a hydrogen halide activator, e.g. hydrogen chloride and a non-reactive organic diluent.  A reactive organic diluent, e.g. benzene or other aromatic or heterocyclic liquid may be employed and where such a diluent other than benzene is employed a mixture of benzylmalonitrile and methylene malonitrile substituted diluent results.  Non-reactive solvents mentioned include sym-tetrachloroethane, nitrobenzene and orthodichlorobenzene.  The hydrogen halide may be produced externally and added to the reaction mixture or may be produced in situ by heating aluminium chloride with sym-tetrachloroethane or by a chlorine substitution of benzene whereby chlorobenzene and hydrogen chloride are produced.  In examples: benzene and 1,1-dicyanoethylene are added to aluminium chloride suspended in the same solvent and the reaction mixture is cooled, the reaction product is hydrolysed with hydrochloric acid and crushed ice and the benzylmalonitrile is isolated by extraction and fractionation and recrystallized from ethanol (I); in a similar process hydrogen chloride is bubbled through the reaction mixture as the reactants are mixed with the catalyst II; and in a similar process to (I) the hydrogen halide is generated in situ by pre-heating the aluminium chloride in sym-tetrachloroethane (III). Specification 795,107 is referred to.
