Patent GB-107783-A (GB)
Title: Improvements in Telegraphy.
Inventor: HEURTLEY ERNEST SYDNEY
IPC: H04L5/02
Filed: 1916-06-06
Abstract: 107,783. Heurtley, E. S. June 6, 1916. Diplex and multiplex telegraphs; receiving systems and apparatus.-In a system of diplex or multiplex telegraphy employing signal impulses having different wave forms as described in Specification 7579/15, the transmitters are geared together in order to obtain different speeds of transmission on the various channels. A device is employed at the receiving end to delay to relative time of action of the impulses on the receivers; while, to correct overcurbing and to shape the signals, a current from a local source is employed. The impulses arriving over the cable i, Fig. 3, are arranged to operate a recorder 8 controlled by impulses having a quickly rising wave front and a recorder 9 controlled by impulses, having a slowly rising wave front. The first brush k' of a commutator delav device l is connected to the cable i through a resistance j across which a compensating winding r, the circuit of which contains resistance s, capacity t, and inductance u, is connected. The delay device consists of four brushes k<1>, k<2>, k<3>, k<4>, the relative positions of which may be varied, and a commutator m, the segments of which are connected to condenser plates. The other plates of the condensers are joined together and connected to earth and to the brush k<4>. As a segment of the commutator passes under the brush k<1>, its condenser receives a charge from the cable and passes on to discharge partly by way of the brush k<2> and the primary winding o of a transformer o, p, the secondary winding p of which is connected to the operating coil q of a non-circuit-closing relay 7 which controls the receiver 8. A further movement of the commutator causes the segment connected to the charged condenser to contact with the brush k<3> connected through resistance, capacity, and inductance v, w, x, y, and z or any combination of these to the operating coil 4 of a non-cirenit-closing relay 7<1> controlling the recorder 9. This non-circuit-closing relay is provided with a compensating winding 5. A further movement of the commutator causes a complete discharge of the condenser when its segment comes under the brush k<4>. If the impulse charging the condenser has a quickly rising wave front it affects the relay 7 more readily than the relay 7<1> and any effect it may produce on the latter relay is neutralized by the energization of the winding 5. Conversely if the impulse has a slowly rising wave front it affects the relay 7<1> more readily than the relay 7 and any effect it may have on the latter relay is neutralized by the winding r. Effects produced by overcurbing are neutralized by passing a current, obtained by a resistance shunt 10, through the coil q. More than two receiving instruments may be employed.

Patent GB-690595-A (GB)
Title: A process for the manufacture of polysiloxane resins
IPC: C08G77/00
Filed: 1951-04-13
Abstract: In making polysiloxane resins from a mixture of silanes containing 1.0 to 1.8 organic radicals per silicon atom, the individual members having the formula RnSiX4-n, wherein each R is an alkyl or monocyclic aryl radical n is 1 or 2 and X is chlorine or an alkoxy radical, the silane mixture is hydrolysed in contact with methylene chloride in amount sufficient to form a solution of less than 60 per cent by weight of the polysiloxane resin formed.  The methylene chloride may be used in admixture with the silanes and this solution added to the water, or it may be mixed with the water and the silanes added thereto or a portion of the methylene chloride may be used to dilute the silanes and the remainder mixed with the water.  An aliphatic monohydric alcohol containing 2, 3 or 4 carbon atoms is preferably used in the hydrolysis medium, in amount of not more than 1/5 mol. per gram atom of chlorine in the silane mixture, when the silane mixture contains a substantial proportion of a diphenyl substituted silane or an average of less than 1.25 hydrocarbon radicals per silicon atom.  The alcohol may either be added to the silane mixture and the resulting partially alkoxylated silane mixture may then be hydrolysed, or to the hydrolysis medium.  Water is employed in amount at least sufficient for complete hydrolysis of the silane mixture. The preferred silanes are methyltrichloro-, ethyltrichloro-, phenyltrichloro-, chlorophenyltrichloro-, trifluoromethyl-, phenyltrichloro-, diphenyldichloro-, phenylmethyldichloro-, and dimethyldichloro-silanes, and the corresponding alkoxy derivatives, particularly the ethoxy and propoxy derivatives. Resin solutions capable of being spray dried and those derived from silane mixtures comprising (a) 25 to 75 mol. per cent of CH3SiX3, (2) 10 to 45 mol. per cent of C6H5SiX3, (3) 0 to 33 mol. per cent of (CH3)2SiX2, (4) 0 to 15 mol. per cent of C6H5 CH3.SiX2, and (5) 0 to 20 mol. per cent of (C6H5)2, where X is chlorine or an alkoxy radical, the sum of (1) and (2) being at least 65 mol. per cent of the mixtures.  The spray-drying is effected in known manner at a temperature above the boiling point of methylene chloride, e.g. at 120-190 DEG  F.  Details of the hydrolysis are given in numerous examples, in some of which the products are diluted with toluene or xylene, and in one (6) the resins are further polymerized by heating at 150 DEG  to 180 DEG  C. The resins may be used for making mouldings by heating under pressure, preferably with a filler, and for protective coatings.

Title: Improvements in electric systems for automatic regulation of the temperature in railway vehicles
IPC: B60L1/02
Filed: 1936-03-24
Abstract: 471,378. Automatic control systems. MOREAU, H. March 24, 1936, No. 8815. Convention date, March 25, 1935. [Class 38 (iv)] Temperature.-In a system for controlling the heating of railway carriages, relays are selectively energized by a galvanometer connected with a Wheatstone bridge and one arm of this bridge comprises a series connection of temperature - sensitive resistances as follows : one at each end of a carriage exposed to external temperature and to wind, one in the conduit 28, Fig. 2, supplying the heated air, and in each compartment, a resistance 32 in contact with the ceiling and subject to its temperature and also to the temperature of the air circulating over it, one 26 subject to the air leaving the ceiling and others 33, subject to the air in the compartment, for example, placed on the rail of the luggage rack. The connections of the galvanometer coil 12, Fig. 1, are adapted to be reversed each time it closes contacts 14, that is to say alternately on excessive and insufficient temperature. This closure connects a coil 16 across one of the members of the bridge and increases the action of the coil 12. The coil 16 actuates contacts 16a, 16b in series respectively with coils 23a, 23b which operate three mercury-in-glass change-over switches 17, 17a, 17b, as shown, to effect the required circuit changes, including the selective operation of the temperature controlling relays 24, 25. The Specification as open to inspection under Sect. 91 describes also a system for heating electrically and alternatively by steam and shown in Fig. 3 (Cancelled). Three control systems C, C<1>, C<2> operate respectively to regulate the temperature of the air, to prevent the temperature of heating air falling below a desired value and to control electric heating resistances 46 under the floor. Locomotive steam when available operates at 41 to close contacts 34 and 40. A relav 38 in series with the controllers C, C<1> is energized to open a steam valve on an air heater and a fan 39 is operated to circulate the air heated. When the carriage is in motion and the generator is operative, contacts 42, 42a close. The former, with contact 44 render air heating resistances 43 operative when no steam is available and the latter energizes the fan at such times; the controllers C, C<1> are then operative on the resistances 43 and a relay 47 opens a contact 47a to de-energize the floor heating resistances 46 when the resistances 43 are active. When the carriage is in service on electrified track a relay 48 is energized and special resistances supplied from the track are placed under the controllers C, C<1>. This subject-matter does not appear in the Specification as accepted.

Abstract: 417,124. Bricks &c. BERRY, A. F., 125, Strand, London. March 23, 1933, No. 8828. [Class 87 (i).] In the manufacture of bricks from a mixture of crushed burnt clay and raw or unburnt clay, the main bulk of clay used is broken up, burnt, and crushed to a suitable degree of fineness before being mixed with a relatively minute percentage, e.g. 5 to 7 per cent, or less than 5 per cent, of unburnt clay. A small proportion of Portland cement or equivalent cementitious material may be added to the mixture of clays or to the burnt clay before it is mixed with the unburnt clay. To impart a colour of the desired kind to the bricks, a small amount of coloured clay or coloured pigment or a mixture thereof may be added to the main bulk of broken up clay before it is burned or to the mixture of burnt and unburnt clays. The plant used for making the bricks is of known type, the main bulk of clay used being fed in a broken up condition into the upper end of a kiln and burned therein, the burnt clay being conveyed to milling apparatus where it is crushed to the desired degree of fineness and mixed with the small amount of unburnt clay, the mixture being then delivered to a moulding press or presses and formed into bricks. The bricks are fed from a drying tunnel to a second kiln where they are burnt, the burnt bricks passing through a cooling tunnel. The bricks while passing from the moulding press or presses to the drying tunnel may be coated with a slurry consisting of a mixture of a suitable colouring material and water, as described in Specification 417,125. The bricks may be pressed to shape between suitable dies so as to contain tapering holes, recesses, or cavities.

Abstract: 663,102. Tapping &c. attachments. MOTOR CAR WORKS NATIONAL CORPORATION, and HUDIK, J. April 1, 1949 [April 1, 1948], No. 8982/49. Class 83 (iii). In a chuck for holding screwcutting tools, more particularly for use on multiple - spindle machine-tools, of the kind in which the outer chuck body 4 is spring - cushioned axially with respect to the spindle 1, which may be either the machine spindle or an attachment thereto, and a friction coupling is interposed between the spindle and the chuck body, the axial spring- cushioning is effected in both directions by means of a helical spring 15 which is interposed between the flanges of a two-piece bush 7, 8 which are clamped in their middle, or rest, position on the spindle and inside the chuck body. The axial feed motion of the chuck body with respect to the spindle 1 away from the mid-position is confined in both directions by the two parts of the two-piece bush fitting against one another. The friction coupling is in the form of a disc clutch, the outer discs 12 engaging grooves in the chuck body and the inner discs 11 engaging grooves in the spindle so as to permit relative axial movement of the chuck body and spindle. The clutch discs are pressed against each other by a helical spring 10, the tension of which is adjustable by means of a nut 9.
