Title: Improvements in and relating to typographical composing and distributing machines
IPC: B41B11/18
Filed: 1938-12-16
Abstract: 522,785. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd., SCOTT, R. H., GORSE, W. F., and HAYWARD, A. S. Dec. 16. 1938, No. 36657. [Class 100 (iii)] Magazines. - In machines having poweroperated mechanism for shifting the magazines, an electrically controlled mechanical relay is provided for preventing operation of the shiftmechanism when matrices are in the distributers or at the magazine-entrances. The relaymechanism, by the action of which the magazines are shifted, comprises a vertically movable striker-rod 1, Fig. 1, which is normally held out of the path of a reciprocating bar 2 by a triplever 3 controlled by an electromagnet 22. When, by the operation of a switch 21, the striker-rod is permitted to swing into the path of the bar 2, it acts through ratchet-mechanism to rotate two cams 11, 12 through an angle of 90 degrees. One cam acts on a locking-bar to unlock the magazines. and the second cam then moves the column up or down, in order to bring, for example, different pairs of magazines into operative relation with two distributers and two assembler-entrances. The electromagnet 22 is not directly operated, but is under the control of a second magnet 25, Fig. 1a, the circuit of which is made by the closing of the switch 21. The magnet 25 acts through levermechanism 26 to project towards the distributers two feelers 27 27a, which are arrested by any matrices on the distributers. If the feelers are unobstructed, the lever-mechanism moves farther and carries another feeler 32 across the upper end of the upper magazine in use. If there are no matrices projecting from the magazine, so that the feeler is unobstructed, the magnet 25 completes the circuit of the magnet 22, and the magazines are shifted. In modifications, the magnet 22 is controlled by a circuit which is completed through matrices on the distributers. In one arrangement, these close the circuit of a magnet 41, Fig. 2, which then holds up a spring-, pressed bar 42. When all matrices have left the distributers, the bar 42 falls and closes contacts 43, which make the circuit of a magnet 44. This magnet moves a feeler 46 over the upper end of the magazine, and, if the feeler is unobstructed, closes the circuit of the magnet 22. The lower magazine entrance and the upper section of the assembler-entrance are swung away by the action of the magazine locking-bar, in order to prevent interference by matrices therein.

Title: Improvements in derivatives of 2-amino pyrimidine and its nuclear substitution products and processes for producing the same
Filed: 1946-12-16
Abstract: N-Substituted 2-aminopyrimidines are manufactured by reacting 2-aminopyrimidine or a nuclear substitution product thereof (e.g. one containing in one or more of the 4-, 5- or 6-positions a halogen atom, a nitro group or an alkyl group of 1-4 carbon atoms) with an aromatic aldehyde (which may be unsubstituted or substituted, e.g. by alkyl or alkoxy groups) in the presence of formic acid.  The process may be carried out by refluxing the reaction mixture, and then rendering it alkaline before isolating the product formed.  Examples describe the reaction of 2-aminopyrimidine and its 4-methyl derivative with benzaldehyde and aminoaldehyde, of 2-aminopyrimidine with 2-ethoxy-1-naphthaldehyde, and of 4-chloro-, 5-nitro- and 4 : 6-dimethyl-2-aminopyrimidine with benzaldehyde.

Title: Improvements in or relating to telephone exchange systems
IPC: H04Q3/00
Filed: 1929-12-05
Abstract: 344,787. Automatic and semi-automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. and WRIGHT, E. P. G., Columbia House, Aldwych, London. Dec. 5, 1929, No. 37311. [Class 40 (iv).] In a conversational circuit comprising a bridge for feeding battery to the called party for calls from an automatic subscriber and also from a manual exchange, means are provided for discriminating between the two kinds of call so that, in response to the answering supervisory relay, the usual current reversal occurs in an automatic call, but in the case of a call from manual, battery is connected to the a wire of the junction, the connection being held by battery fed forward over the b wire. The invention is described as a modification of the penultimate (battery feed) selector shown in Fig. 3 of Specification 324,982, [Class 40 (iv), Telephones &c.], and renders unnecessary any further repeater for supervisory signals to the manual exchange. The Figure shows only a part of the conversational switch circuit equipped with discriminating relays OS, ES, the byepass control circuit being omitted. The circuit is tested over wire T in both kinds of calls, but the operator's first selector connects ground to W instead of to H to operate OS which connects ES to the b wire, disconnects this wire from the byepass, and connects ground on W to H to mark the conversational switch in the banks of the byepass associating switch. For calls from a manual exchange the complete byepass route is maintained until all the digits have been sent, and the speaking connection to the penultimate selector is not completed until this occurs. Relay ES connects ground at es1 to hold the impulse relay in the byepass circuit (22-volt battery in the operator's cord circuit would be unsuitable if the impulse relay remained connected to the b wire as in the prior Specification). When the called line has been tested and rung, the ring-tripping relay (FS) in the byepass circuit connects up the answering relay DS, and a further relay (BS) in the byepass connects ground over AS to the a wire, the battery connected winding of AS being disconnected at os3 from the b wire. When the call party replies, DS connects battery over AS to the a wire and connects ground over AS instead of over ES to the b wire. As relay AS comprises two windings on the same core, unbalance due to the fact that one winding is energized by 22-volt battery and the other by 48-volt battery in the case of manual calls is avoided.

In automatic arc welding with a continuous metal electrode, the electrode 6 is passed through an orifice 16 in the base 17 of a container 13 holding a powder having a magnetic component, e.g. 50 per cent iron, and the powder is continuously mechanically thrust towards the electrode and forms a coating having the same diameter as the orifice 16 and adhering to the electrode due to the magnetic effect of the welding current. The electrode 6 is fed into the container by feed rollers and drives a pair of rolls 28, 29 geared to a rotor 22 carrying blades 18. The powder is dropped through a tube to a point near the outer ends of the blades 18 which thrust it towards the electrode. The inner ends of the blades 18 coincide with the edge of the orifice 16. The base 17 of the container may slope down towards the orifice 16. Specification 608,270 is referred to.

Abstract: 1,200,226. Making hollow-ware; stamping; rolling discs. ROTARY PROFILES ANSTALT. 15 Aug., 1967 [19 Aug., 1966], No. 37506/67. Headings B3A, B3M and B3Q. A method of drawing a hollow article from a metal sheet 54 comprises applying pressure to the central zone of the sheet and forcing rollers against at least one surface of the sheet in the peripheral zone to urge material from the peripheral zone towards the centre. Apparatus for performing the method comprises cages 24, 48 containing rollers 26, 46 which need not be pinned to the cages and the axes of which are inclined to radial lines passing through the rollers. As a punch 44 draws the sheet into a die 10, the cates are rotated in opposite directions by worm gears 21, 40 to reduce, or maintain constant, the thickness of the clamped margin. Roller bearings 20, 38 facilitate rotation of the cages. The process obviates the need for annealing, or reduces the number of annealings required. In a modification, the bore of the die, or the bore of the die and the surface of the punch or, Fig. 3, only the surface of the punch may be additionally lined with skewed rollers 62 which rotate with the punch for urging the material downwardly. These rollers 62 are in a cage fixed to the punch and assist in producing a wall of uniform thickness or of different thicknesses. An end pad 70 is supported by a thrust bearing 72.

Abstract: 1479697 Production of preplasticized vinyl or vinylidene halide polymers B F GOODRICH CO 28 Aug 1974 [29 Aug 1973 1 April 1974] 37519/74 Heading C3P A process for forming preplasticized vinyl-, or vinylidene halide homo- or copolymers comprises forming a monomer premix by mixing the monomer or monomers to be polymerized, a plasticizer for the finished polymer in an amount 5-100 parts by weight of plasticizer based on 100 parts by weight of monomer and the aqueous reaction medium, homogenizing the premix to form an emulsion in which the solids have a particle size of 0À5-15 microns, passing the homogenized premix to a reaction zone, emulsion polymerizing the homogenized premix in the presence of a suitable catalyst therefor and at a temperature below the glass transition temperature of the polymer being produced, and thereafter recovering the plasticized vinyl resin. Conventional plasticizers may be used, e.g. phosphates and phthalates. Further plasticizer may be incorporated in the vinyl polymer product. The aqueous medium usually contains an emulsifier, e.g. in an amount up to 6% by weight of the monomer charge, and it may be added either prior to polymerization, e.g. when the premix is homogenized, or during the reaction. Temperatures of polymerization in the range 15-75 C. are preferred. Freeradical initiators may be used to initiate the polymerization process. Any convenient means of homogenization may be used. The pH of the reaction system may be adjusted by the use of ammonium hydroxide. In the specific examples a pre-mix of vinyl chloride and dioctyl phthalate at various pHs (3À3, 7À1, 11À3) is homogenized and then polymerized using batch polymerization and proportioning the premixes containing as emulsifier: sodium lauryl sulphate, dodecyl benzene sodium sulphonate, and lauryl alcohol.
