Title: Improvements in or relating to teleprinters
IPC: H04L17/16
Filed: 1955-01-28
Abstract: 764,057. Printing-telegraph receivers. SIEMENS & HALSKE AKT.-GES. Jan. 28, 1955 [Jan. 28, 1954], No. 2714/55. Class 40 (3). In a teleprinter in which an intermittently. driven shaft sets selector elements and during the final portion of each revolution actuates a member for controlling the printing operation, a retarding device is included between the control member and a member which initiates the printing operation to ensure that the drive for the printing mechanism is not started until the setting of the selector elements is complete. As shown, a projection 4 on a cam 3 on the printing shaft 2 is normally engaged by a tooth 5 on a lever 6 pivoted at 7 and connected by a pivot stud 8 to a release bar 9. A control arm 14 has an end 12 engaging a cam 10 on the receiver shaft 1 which during the second half of its revolution rocks a shaft 13 so that a member 16 extends a spring 17 connected to a latching lever 19. The sudden movement of the arm 12 on disengagement with the nose 11 of the cam 10 causes the member 16 to rotate beyond its normal position so that a lateral extension 18 engages and depresses the lever 19 to remove its tooth 21 from latching engagement with a lateral extension 20 on the bar 9 which is pulled to the left by a spring 22. The lever 6 is rocked and projection 5 raised so that the printing shaft 2 is rotated. The lever 6, returned to its normal position by the engagement of its extension 23 with the nose 4 of the cam, moves the bar 9 to the right in which position it is retained by the tooth 21 on the lever 19.

Title: Improved polymerisation process
Inventor: SMITH RONALD PHILIP
IPC: C08F14/26
Filed: 1958-02-03
Abstract: Aqueous colloidal dispersions of tetrafluoroethylene polymers are obtained by polymerizing tetrafluoroethylene in the presence of water containing a water-soluble catalyst and, as an ionizable dispersing agent, a water-soluble polyfluorinated sulphonic acid or salt having the formula RSO3X where R is either a radical CnF2n+1 or a radical having 4, 5 or 6 carbon atoms in a ring and the formula CnF2n-1, n being an integer from 4 to 18, and X is hydrogen, a metal ion, or ammonium or a substituted ammonium ion.  Catalysts mentioned are peroxy compounds (e.g. ammonium and alkali metal persulphates, and disuccinic acid peroxide) and azo compounds, e.g. disodium gamma, gamma1 - azobis (gamma - cyanovalerate); suitable amounts being 0.001 to 0.5% by weight of the water.  Dispersing agents specified are perfluoro n-pentane sulphonic acid, ammonium and potassium perfluoro-n-hexanesulphonates; sodium and potassium perfluoro-n-octanesulphonates; sodium perfluorocyclohexane-sulphonate; and sodium, potassium and ammonium perfluoro-4-methylcyclohexanesulphonates.  The polymers may be tetrafluoroethylene homopolymers, or copolymers with up to 25 wt. per cent of another ethylenically unsaturated compound, e.g. vinyl or vinylidene fluoride, monochlorotrifluoroethylene, hexafluoropropylene, hexafluorocyclobutylene, ethylene or styrene. The dispersing agent may be added, preferably in amounts of 0.01 to 0.5% by weight of the water, before initiation of, or during the course of, the polymerization; in the latter case the first addition should be made before the polymer formed exceeds 10% by weight of the aqueous phase plus polymer.  A stabilizer, e.g. 0.1 to 12 wt. per cent of a C12 or higher saturated hydrocarbon which is liquid under the polymerization conditions, e.g. octadecane, eicosane, tetradecane, cetane or paraffin wax, may be added before initiating the polymerization.  The dispersions, prior to use for film-forming, coating or impregnation, may be concentrated by electrodecantation and may subsequently be baked above the sintering temperature (327 DEG  C.).

Abstract: 1,163,806. Operating car and landings doors in lifts. DEWHURST & PARTNER Ltd. 29 Aug., 1968 [30 Aug., 1967; 23 Jan., 1968], Nos. 39583/67 and 3545/68. Heading B8L. A coupling device, for coupling a lift car door to a landing door for opening and closing, comprises a guide 11, Fig. 1, on the car door, and a pivoted member 14 on the landing door which normally clears the guides but which is latched in the position shown by latches 19, 22 on the landing door when the doors are opened. The doors are shown latched together and nearly closed. As they close a roller 23 runs up a ramp 27, thus raising the latch 22 and allowing the latch 19 to pivot downwards. This pivots the member 14 into a vertical position with the rollers 16, 17 out of contact with the guide 11 and engages a hook 26 on latch 19 to engage a projection 25 thus holding the landing door closed. When the car door opens the side 12 of the guide 11 engages roller 16, pivots member 14 and brings the roller 17 into engagement with the side 13. This raises the latch 19 to release the landing door and as the two doors open the latch 22 drops down off the ramp 27 locking the doors together by holding the latch 19 in the raised position shown. The links 28 may be replaced by a threaded rod to provide finer adjustment. In a second embodiment the fixed guide is replaced by hinged guides 30, Figs. 2, 5, which are spring-loaded into the erected position by springs 36. This arrangement facillitates recoupling the doors should one be opened manually for servicing. Fig. 7 shows similar hinged guides 42, 43 with retracting mechanism 49-54 which retracts the guides when the lift door is closed by moving the rod 49 to the left.

Abstract: 1536723 Automatic telephone exchanges TEL-TONE CORP 29 Jan 1976 [17 March 1975] 3566/76 Heading H4K A port selector comprises at least one port and a plurality of links, the links being connectible to the port for seizing said port, each link including make-busy means for creating a busy signal when one of the other links seizes the port. The selector is only used during the setting up operation of a call; the selecting achieves a more efficient use of the port and thus the number of ports required is reduced. In the embodiment, Fig. 2, the selector has three ports 17, three groups of links 23, connecting respective ones of three groups of line finders 15 and first selectors 19; each group has a scanning switch 13. A clock 24 and an address generator 25, common to all the links, is used for addressing the links cyclically. The scanning switch 13 scans its associated line finders and when it finds one connected to a link 23 with an available port 17, it "points" to it so that when a telephone connected to one of the incoming lines 11 goes OFF HOOK it is connected via that line finder to its first selector 19 through the associated port 17. When the associated first selector receives loop current across associated tip and ring leads it returns a ground to the linefinder 15 via link 23 to complete the connection. Signals generated by the OFF HOOK telephone are then applied to the port 17 which diverts these signals, to a signal processor, if necessary. Processed signals are then applied to the first selector through port 17. When a link and its associated port are "seized" the link produces an ACTIVE signal, all ACTIVE signals for links served by the same port are ORed to produce a PAVAIL signal which forces all the other links to produce a busy signal which informs their associated line finders that the port is busy. This causes the scanning switch connected to these line finders to scan for another line finder connected to a link with an available port. The link is the subject of the divisional Specification 1,536,724.
