Title: Improvements in or relating to telephone systems
IPC: H04M15/10
Filed: 1931-01-19
Abstract: 371,355. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., (formerly AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd.), Strowger Works, and TAYLOR, R., 30, Oulton Road, Wavertree, both in Liverpool. Jan. 19, 1931, No. 1804. [Class 40 (iv).] A final selector controlled by multipled common equipment, in the event of a busy condition, steps to the eleventh position, in which the common equipment is dissociated and a busy signal is transmitted over cam springs, while in the event of an unequipped line being called, the connection is switched through to number unobtainable tone apparatus and the common equipment is dissociated. Another feature of the final selector described is claimed in Specification 371,358. Normal operation. Assuming the switch is seized over the lower set of wires, relay WS energizes in series with line relay AC in the control equipment, locks and connects up the associating relay K. Release relay BC and dialling relay C (right winding) energize, and the first series of impulses are repeated to the vertical magnet VM and relay C (left winding). The latter relay then falls back and connects up change-over relay E which re-energizes relay C. The second series of impulses are repeated to the rotary magnet RM and relays RN, C, and relays C, E then relapse in turn, connecting test relay H momentarily to the test wiper. If the wanted line is free, relay H energizes, locks and closes a preliminary continuous ringing circuit which is replaced by the usual intermittent ringing circuit through ring-trip relay F when relay J pulls up due to the relapse of relay E. A metal rectifier MRC in series with relay H prevents false operation by booster metering battery on the test terminal. Alternatively relay H could be replaced by a polarized relay. The reply of the called party energizes relay F which locks and connects up back-bridge relay DC in the control equipment, applying booster metering battery to the incoming test wire. Relays J, RN fall back and relay. B energizes and completes the connection in the final selector, whereupon feed relays A, D operate, the former locking relay B which serves to control release and the latter reversing the current on the calling side in the usual manner. The disconnection of relay AC initiates release of the control equipment. Unallotted numbers. The upper line terminal is connected to battery, so that relay F pulls up immediately after the operation of relays H, J, releasing relays J, RN and connecting up relay B to complete the connection to unallotted number equipment which gives a tone to the calling party. Wanted line busy. Relay H is inoperative, and when relay J pulls up, a fresh circuit is closed for the rotary magnet RM under the control of relay DC for stepping the switch to the extreme position in which cam springs S are operated. Since relay DC now holds, relays J, RN fall back and connect up relay B, and busy tone and flash are applied through feed relay A, relay B being held during the flash periods over its left winding.

Patent GB-785174-A (GB)
Title: A process for the production of emulsions
IPC: C08G77/00
Filed: 1956-01-19
Abstract: An emulsion is made by polymerizing or copolymerizing one or more organosiloxanes of the general formula RnSiO 4-n/2 , wherein each R is a monovalent hydrocarbon or halogenated hydrocarbon radical, some of which may be replaced by H atoms, and n has an average value from 1 to below 3, while the siloxane(s) is dispersed in a finely-divided state in an aqueous medium by reacting the dispersed siloxane(s) with a catalyst which is a strong mineral acid or a strongly alkaline compound.  The process may be effected either by dispersing the siloxane in water, preferably by using an emulsifying agent, adding the catalyst thereto and allowing the emulsion to stand, with or without agitation, at the desired temperature until the siloxane has reached the desired size of molecular aggregation, or by adding the catalyst to the siloxane prior to or simultaneously with dispersion. Preferably an emulsifying agent is dispersed in the siloxane and the mixture is then added with agitation to water to give the desired emulsion and the catalyst is then added and polymerization allowed to proceed. Polymerization may be effected at room temperature, or at above 100 DEG  C. in a closed system, but preferably at 25 DEG  to 80 DEG  C.  The siloxane may be recovered from the emulsion merely by breaking the latter, e.g. by adding salts such as NaCl or by evaporating the water.  If the viscosity of the initial siloxane is too high for adequate dispersion, a little solvent may be used. Siloxanes specified contain saturated, unsaturated, cyclic or halogenated aliphatic or aromatic or halogenated aromatic hydrocarbon radicals or H atoms.  The final siloxanes may contain hydroxyl terminal groups.  Catalysts specified are HCl, HBr, HI, H2SO4, HNO3, H3PO4 NaOH, CsOH, LiOH and quaternary ammonium hydroxides of the formula R14NOH, where each R1 is an alkyl, aralkyl or hydroxyalkyl radical, or their salts, and are used in amount, e.g. of 1 alkali mol. per 100 to 50,000 Si atoms, or 15 to 80 per cent of acid based on the weight of the aqueous phase of the emulsion.  Where quaternary ammonium salts are used, acids or alkaline materials must be added to effect polymerization.  Many cationic, anionic and non-ionic emulsifying agents are specified. The emulsions may be used for release agents or for coating compositions, particularly latex paints.  Examples are given.

Title: Improvements in tapering and copying attachments for lathes
Inventor: LAYTON DUDLEY AUSTIC
IPC: B23Q35/26
Filed: 1954-01-26
Abstract: 766,662. Copy-turning. LAYTON, D. A. Jan. 25, 1955 [Jan. 26, 1954], No. 2348/54. Class 83 (3). Stylus means for a copying and tapering attachment, of the kind adapted for mounting on a lathe carriage and including a toolcarrier slidable transversely to a work surface whilst the attachment is traversed therealong under the action of the stylus mounted on the carrier and directed away from the work surface to co-operate with a relatively stationary copy-bar towards which the carrier is urged by a spring, comprises a pivoted stylus adapted for retraction in relation to the toolcarrier under the influence of the carrier spring to permit the carrier to withdraw from the work-surface for the non-operative return traverse of the attachment. A mounting block 4, Fig. 2, of the stylus is secured to the end of the tool-carrier 5 and is recessed to take the pivoted stylus 1, Fig. 3. The recess carries an adjustable stop 11 against which the stylus is held by a latch 8, Fig. 2, during operative traverse of the tool-carrier. One latch bears against the forward face 1f, Fig. 3, of the stylus. A spring-pressed plunger 10 also bears in a recess 1h of the forward side of the stylus to urge the latter into the operative position. On the return movement of the tool-carrier the latch 8, Fig. 2, is lifted by a handle 9 and the pressure of the tool-carrier forcing the stylus against the copying bar (not shown), deflects the stylus against the action of the plunger 10, thus relieving the tool for its non-operative return movement. Operation of the latch at the end of this movement locks the stylus again and restores the tool-carrier to a position for a fresh cutting operation. Specification 698,662 is referred to.

Patent GB-690002-A (GB)
Title: Improvements in or relating to recording instruments
IPC: G01D15/20
Filed: 1951-02-07
Abstract: 690,002. Electric indicating systems. BRISTOL'S INSTRUMENT CO., Ltd. Feb. 7, 1951, No. 3031/51. Class 40 (i) [Also in Group XIX] In an instrument for recording a plurality of variables, wherein voltages proportional thereto are sequentially balanced automatically in a potentiometer, the recording member is moved by an electric motor responsive to unbalance of the potentiometer and a second motor moves the recording member to effect a marking on a chart, the second motor being delayed in operation until the potentiometer balancing motor is de-energized. As shown, thermocouples 86-88 are connected in turn by a rotary switch 78 to a self-balancing potentiometer 12, 18. The outof balance potential is applied at 32 to a modulator-amplifier 28 the output 33 of which is an A.C., of power frequency, varying in magnitude and phase sense relative to the A.C. input 31 according to the magnitude and sense of the out-of-balance input potential. The modulator output energizes a two-phase induction motor 27 coupled to the slide 15 of the potentiometer resistor 12 which is thereby driven to the balance position. The angular position of the slide is then a measure of the thermo-couple voltage and produces through shaft 16, drum 46 and a cord 47, a corresponding linear position of a carriage 50 along an extended pinion 52. The carriage has a recording type wheel 56 mounted therein. A shaft 65 driven by a two-phase induction motor 72 periodically rocks, through a cam 66, a frame 61 which rocks the carriage 50 about the pinion 52 to bring the operative type 55 of the recording type wheel 56 into contact with the record sheet 41 which is advanced at constant speed. The shaft 65 also periodically steps a shaft 77 through a cam actuated ratchet wheel 93, which advances the switch arm to connect the next thermocouple into the measuring circuit, and by way of gearing 75 rotates the type wheel to bring a new type member 55 into operative position. Shaft 65 also periodically closes contacts 101 connected in series with the contacts of a relay 105 across the phase-shifting capacitor 92 associated with one winding of the motor 72. Relay 105 is energized to close its contacts while the measuring system is unbalanced, and consequently if balance has not been attained when contacts 101 close, motor 72 is stopped until balance is achieved. Alternatively, the motor 72 may be caused to "creep" instead of stopping, thus identifying the thermocouple circuit concerned but not holding up recording indefinitely. Specification 602,460 is referred to.
