Title: Improvements in or relating to control circuits,e.g.for automatic telephone exchanges
IPC: H04Q3/545
Filed: 1966-07-11
Abstract: 1,111,018. Automatic exchange systems. TELEF0NAKTIEBOLAGET L.M. ERICSSON. 11 July, 1966 [15 July, 1965], No. 31119/66. Heading H4K. In an exchange controlled by a computer P, a single wire x serves to effect energization and release of a selected magnet RX in a switching network XV and also to supervise its condition. The computer receives selecting signals from lines L1 ... Ln and controls a fast operating unit SMR to send address and operating signals to a relay unit RMR which includes a marker ADR. Pulses T1 . . . T3 control contacts S1 . . . S3 and also render selecting contacts al . . . an effective at the proper time to select the magnet RX through the marker ADR. When RX is to be energized, circuits are made by relay K8 through both windings of differential relay K7 so that this relay pulls up if the wire x proves to be faulty. When RX is to be released, a test is made first to ensure that it is actually operative. Relay K1 responds when connection is made to RX, followed by K6 if it is up. Relay K5 indicates its definite release. These relays control supervisory circuits leading through a matrix XT to the computer. During the process of release the computer runs through all the addresses to correct its memory, if necessary, regarding the conditions existing in the switching network.

Title: Improvements in train control systems
IPC: B61L3/02
Filed: 1925-12-09
Abstract: 266,485. Automatic Telephone Manufacturing Co., Ltd., and Hudd, A. E. Dec. 9, 1925. Electrical systems, non-automatic; track apparatus for actuating signals on and for stopping trains.-In circuit with an electromagnet 18 which controls the brake apparatus on a train and is energized by current collected from track ramps 1, there are arranged large capacity condensers, such as electrolytic cells 17, whereby very brief contact at short track ramps is sufficient to effectually control the electromagnet. The collector shoe 3 slides vertically and by the tapering portion of the spindle 4 slides the piston 8<a> and causes the ball 43 to rise and open the normally closed valve 44 and allow air pressure from the chamber 8 to escape by a pipe 10 and a valve 20 when the electromagnet 18 is deenergized. Reduction of pressure in chamber 8 permits the diaphragm valve 13 to open and pressure passes from pipe 50 to cylinder 14, the piston of which thrusts the driver's valve handle to service position. Positive and negative energization of the magnet 18 causes its armature 19 to rock in opposite directions, both of which force the valve 20 on to its seating and thus prevent a brake application. At an energized ramp the condensers 17 are charged as the shoe 3 passes. and the magnet. 18 is excited, it may be after the ramp has been cleared. If the ramp is positively charged, as for a clear signal, the armature 19 rotates counterclockwise and merely closes the valve 20, thereby causing air pressure in the pipe 10 to move the piston 8<a> to normal position and allowing the valve 44 to reclose. At a negatively energized ramp as at, a caution signal. if the apparatus is in normal position, as shown, the armature 19 rocks clockwise and in addition to closing the valve 20, deflects the stop 26' and allows the latch 25 to drop and the valve 54 to open. The stop 26<1> also carries a quadrant 24 which is put in gear with the pinion 27, driven by a turbine 20<a> fitted with an escapement gear, by means of which the stop 26<1> can only be replaced bv the air pressure on the diaphragm 26 when a predetermined time interval has elapsed after the tripping of the stop 26<1>. If a second ramp, negatively energized, is passed during this interval the armature is locked against movement by the latch 25, and consequently the valve 20 remains open, and a brake application is initiated. By selection of the distance between ramps, the permissible speed of the train between these ramps is determined. 'To cancel a brake application, the lever 34 is rocked and by means of the lug 30 on the sliding bar, which is raised by spring 33 when the pressure above the diaphragm 32 is reduced, rocks the armature 19 and closes the valve 20. In order to economise energy, if a train stops over an energized ramp, the magnet 36, of high resistance, opens contacts 37 and inserts a resistance 38 in series with the condensers and magnet 18. Specifications 266,605, 266,611, and 267,388 are referred to.

Filed: 1922-11-15
Abstract: 202,562. Shannon, E. F. Nov. 15, 1922. Drawers and drawer fittings. -Drawers adapted to be pulled fully out of their casings and supported in that position by slides, carry one slide f attached to each drawer side g, a bearer bar a attached to each side of the drawer casing, and a middle slide d provided with rollers e arranged to travel between each pair of slides a, f. On pulling out the drawer, the slides f run on rollers e until the stops f<4> on the former engage stops d<4> on the slides d, when the latter move with the drawer until engaged by stops. At the front end of each slide d is pivoted a cam-shaped member x which normally bears upon the top edge of the slide f so that the catches d<4>, f<4> engage. When the members x are turned 'by hand into the position shown in Fig. 4, one catch may be lifted over the other and the drawer totally removed. When the drawer is replaced and pushed fully in, side extensions of the drawer front g<4> engage the cam curves of the members x and move them into operative position, so that the drawer cannot be removed until the stiffly working members x are moved by hand into inoperative position.

Title: Improvements in or relating to metal vapour jet ejectors
IPC: F04F9/00
Filed: 1924-12-30
Abstract: 233,653. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. May 8, 1924, [Convention date]. Aspirating-apparatus, ejector.-The jets in a multi-stage mercury or similar metal - vapour jet exhausting apparatus are all annular. Mercury 32 is vaporized by an electric heating resistance contained within a recess 33 in a heat - insulated chamber 31 and flows through a vapour supply tube 35. The vapour passes from the tube through openings 38, 39 leading to annular jets 36, 37. The size of the apertures 39 may be regulated. The jet 36 is formed by the outer wall of the tube 35 and the inner wall of a hood 41 resting on a shoulder 42 on the tube 35. The jet 37 is formed by the outer wall of the hood 41 and the inner wall of a hood 43 secured by means of a screw 44 to a cover 45 of the tube 35. The parts forming the annular jets may thus be readily removed for cleaning. A tube 46 in communication with the high vacuum conduit and arranged round the jets is cooled by liquid circulating through a jacketing vessel 47. The low vacuum conduit communicates with the outlet 50 of a pipe arranged in a helical coil 51 in the vessel 47 and at its other end being connected to a chamber 52 into which the lower end of the pipe 46 opens. The condensed mercury flows from the chamber back to the receptacle 31 through pipes 53. The provision of the coil 51 prevents mercury being sucked out of the ejector should a leak in the high vacuum conduit occur. In a modification the chamber 52 and the coil 51 are omitted. Lead, tin, bismuth, cadmium, zinc or the like may be used instead of mercury. The ejector may be made of metal or glass.

Title: A process for the manufacture of thermosetting resinous materials
Filed: 1950-12-22
Abstract: A thermosetting resinous material is made by reacting a polysiloxane containing 0.9 to 2.1 silicon bonded monovalent hydrocarbon radicals per silicon atom, the radicals being saturated aliphatic radicals containing less than seven carbon atoms or monocyclic aryl radicals and the siloxane containing 0.05 to 2 silicon bonded functional groups, viz. alkoxy and/or acyloxy radicals, per silicon atom, the remainder of the valencies of the silicon being satisfied by oxygen atoms, with glycerine in such an amount that the ratio of siloxane functional groups to hydroxyl groups is from 0.1 to 1, and thereafter reacting the siloxane-glycerine ester so formed with an acid ester formed by reacting a dicarboxylic acid or anhydride thereof with glycerine in such an amount that the molecular ratio of acidic compound to glycerine is from 1.33 to 2, the siloxane-glycerine ester and acid-ester being reacted in such an amount that the ratio of the total glycerine-hydroxyl groups to the sum of the siloxane functional groups plus the acid groups is from 0.9 to 1.2.  The alkoxypolysiloxanes used may be made according to the process of Specification 685,173, and the acyloxy-polysiloxanes may be made by reacting the alkoxypolysiloxanes with monocarboxylic acids. The specified radicals of the polysiloxanes are: hydrocarbon radicals such as methyl, ethyl, propyl, butyl, cyclohexyl, cyclopentyl, phenyl, tolyl, chlorophenyl and xylyl, alkoxy radicals such as methoxy, ethoxy, butoxy and stearyloxy, and acyloxy radicals such as benzoyloxy, 2-ethyl-hexoyloxy, stearoyloxy and linoleoyloxy. Dicarboxylic acids specified are phthalic, malonic, fumaric and maleic.  The reaction of the polysiloxane and glycerine may be effected at 30 DEG  to 300 DEG  C., and that of the resulting ester with the acid ester is preferably effected at 90 DEG  to 250 DEG  C. These reactions may be effected in the presence of solvents such as aromatic hydrocarbons, alcohols and ketones.  The resins may be thermoset by heating at temperatures up to 250 DEG  C.  In examples: (1,2) an isopropoxy-polysiloxane, prepared by reacting a mixture of phenylmethyldichloro-, phenyltrichloro- and methyltrichlorosilanes with isopropyl alcohol and hydrolysing the resulting alkoxy-chlorosilane with water, was heated with glycerine and the resulting ester was heated with glyceryl phthalate.  The resulting material was then dissolved in cyclohexanol or cyclohexanone; (3, 4, 5, 6) an isopropoxypolysiloxane, prepared from phenylmethyldichloro- and phenyltrichloro-silanes, was reacted as in example (1); (7) an isopropoxypolysiloxane, derived from phenylmethyldichloro- and phenyltrichloro-silanes, was reacted with benzoic acid and the resulting acyloxy-polysiloxane was reacted as in example (1). Metal panels may be coated with the resins.  Specifications 663,599, 691,014 and 691,015 also are referred to.

Abstract: 938,016. Shaping grinding wheels. A. A. JONES & SHIPMAN Ltd., and J. HOULDSWORTH. Aug. 16, 1961 [Sept. 12, 1960], No. 31342/60. Class 60. A grinding wheel profiling apparatus is mounted to one side of the wheel-head housing 2 and is swingable as a unit about a fixed axis so that the forming tool 21 moves into and out of contact with the grinding wheel 1 along an arcuate path. In the embodiment described the invention is applied to a moving-table horizontal surface grinder, the fixed axis of swing of the profiling apparatus being that of a bar 5, parallel to the axis of the grinding wheel spindle, the bar being extended to form trunnions 6 on either side of a bracket 4 which extends from the wheel head housing 2 and may be heat-insulated therefrom ; two bosses 8, on the body 7 of the forming apparatus, pivot about the trunnions 6 to allow the apparatus to swing in a plane normal to the surface of the work-table. 3. The weight of the apparatus may thus be applied to the forming tool 21, or it may be counterbalanced by a weight or springs. - A pantograph mechanism of the form described in Specification 924,393 enables a stylus 17 to transmit to the tool 21 the profile of a template 18, the mechanism being coupled to the body 7 by pivots 23; the tool arm 20 is rotatable about its axis 24 by a lever 25, the tool itself being mounted in a turret 26 of the type disclosed in Specification 916,294. Preliminary setting of the profiling tool relative to the work is made by a hand-wheel 15 which effects rela. tive movement between the pivoted body portion 7 of the forming apparatus and the wheelhead 2 through a screwed rod 10 pivoted at 9 to the body 7 and engaged by a worm-rotated nut 11a carried in a swivelling housing 12 attached to the bracket 4; sideways movement during the swinging of the body portion 7 is prevented by an arcuate slide 16, Fig. 4, on the body engaging a corresponding groove 16a in the bracket. Fig. 4 also shows the rocking arm 45 of a dial indicator 47 checking the setting of the tool 21, the indicator unit being pivoted at 43 so that it may be swung into and out of its operative position, a hinged wheelguard 41 giving access to the tool-holder. A shoot 27 is connected by a flexible pipe 29 and by a sliding joint 32 in a junction box 30 to a dust extraction system, the mouth 35 of the shoot being vertically adjustable to suit the diameter of the grinding wheel. A further exhaust shoot 37 is connected to the box 30 to collect dust from the wheel-forming operation, a baffle plate 40 in the box 30 enabling the operator to select by a lever 39a the required exhaust system.
