Title: Improvements in or relating to railway signalling apparatus
IPC: B61L3/02
Filed: 1920-03-23
Abstract: 168,085. Sykes Interlocking Signal Co., Ltd., W. R., Tiddeman, E. S., and Russell, F. V. March 23, 1920. Track apparatus actuating signals on trains and for stopping trains.-In railway signalling apparatus, a notched plunger actuated by track ramps controls devices for the application of the brakes and audible signals : it is normally locked in its set position by a bolt or detent adapted to be withdrawn when a trip device or auxiliary plunger is displaced by an auxiliary track ramp or by a wider ramp than is necessary to operate the main plungers. The notched plunger 11, the controlled lever 17 and its associated lovers, with the electromagnet 31, are constructed and operated in the manner described in Specification 138,208. While the projection 19 on the lever 17 abuts against the lever 20, the toggle levers 24, 25 are held in the position shown; when the electromagnet 31 is energized by the passage of the plunger over an electrically live ramp, it attracts its armature 30 and assists in maintaining the straight position of the toggle levers. The valve 39, normally held closed by the lever 17, controls the pressure in the pipe 42 which contains a two-way valve controlling the air-pressure brakes and the alarm signal. When a track ramp 16<a> of a home signal in the " on " position is overrun, the control lever 17 is operated and a locking-finger is moved out of a notch in the resetting-plunger 51; the spring- pressed bolt 46 and plunger 51 move simultaneously and oppositely, the bolt 46 entering an aperture in the raised plunger 11 to prevent the driver from releasing the brakes until he has descended to the track and pressed the resetting- plunger 51, as described in Specification 138,208. The plunger 51 has a second notch 81 engaged by a bolt 82, which is an extension of the piston-rod 64 of the two-way valve. The lower end of the rod 64 carries a sleeve 83 engaged by the bifurcated end 84 of a lever 85 on a pivot 86. The lever 85 has a pin 88 which projects into a longitudinal slot in each of a pair of bars 90 pivoted on the arms 92 of a Y-shaped lever 93 supported on a pivot 94. The auxiliary track ramp 16<b> is secured by a bracket 16<c> to the insulated base of the main ramp 16<a>. Normally the two-way valve is in position to connect the valve 39 to the pipe 61 and the a.udible signal, and when the plunger 11 is operated by the ramp of a distant signal the detent or bolt 46 cannot enter the aperture 50 in the plunger owing to the engagement of the piston-rod extension 82 in the notch in the plunger 51. When the plunger 11 is operated by the ramp of a home signal, the arm 93 is operated by the auxiliary ramp, the bolt 82 is withdrawn and the two-way valve is actuated to connect the valve 39 to the pipe 60 with the different sounding alarm. If the notched plunger is also unlocked bv the projection 19 of the controlled lever 17, the detent 46 enters the aperture 50, the brakes are applied and can only be released by the driver descending to the track. Specifications 6499/15 and 112,191 are referred to.

Abstract: 166,639. Ford, A. March 24, 1920. Ploughs; power cultivation of land.-A motorplough of the type in which the implement hauls itself along a cable anchored at the headlands is provided with automatic means for reversing and moving into position for the next set of furrows after arriving at each headland. The cable A is secured to carriages having anchor discs J and provided with horizontal wheels over which chains or the like anchored at FG, F'G' pass. The middle wheel of each carriage is adapted to be turned by a ratchet lever H, H' to cause the anchor carriage to move along the chain and thus take up the position for the new set of furrows, the ratchet lever being attached to the cable A and retracted by a spring. The implement frame is supported by wheels K, K, K<1> and provided with a hauling-pulley secured to a pinion N<1> driven by a pinion N on a countershaft rotated from the engine L through a reverse gear M controlled by a compressed-air-actuated cylinder P. The shares B are keyed to shafts C which are connected by chain and sprocket gear with a shaft R adapted to be driven by the pinion N'. A pinion S is keyed to the shaft Rand meshes with a pinion pivoted on a stud on the pinion N' the second pinion being connected through another pinion with a gear wheel S' integral with a brake drum loose on the shaft R. During the traverse of the plough the shaft R remains at rest, the drum and pinion -S' rotating around it. On tightening the brake band of the drum, the drum is held stationary and the pinion S and the shaft R are driven by the rotation of the pinion N'. The movement of the shaft R lifts the one share and lowers the other through the sprocket-and-chain connection with the shafts C and through a lever E<2> driven by a crank-pin on the end of the shaft and connected by links to the stub axles of the wheels K, K sets over the plough in position for the next furrow. One of the sprocket wheels of the plough-lifting gear is formed with a slot D' in which a pin engages, this pin being connected by a link to a bell-crank lever controlling mechanism for freeing the brake band from the drum and for moving the piston in the reversegear cylinder P and being operated when the shares have been swung into position for the reverse movement. The brake band is tightened when the plough approaches the headlands by one or other of the rods W, W<1> engaging and being lifted by an obstruction on the cable A, thus turning a shaft T' and operating a face cam T<3> to close the band S<2>.

Title: Improvements in or relating to signal-receiving systems
IPC: H03G3/26
Filed: 1942-06-26
Abstract: 559,780. Wireless receiving circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 26, 1942, No. 8769. Convention date, June 26, 1941. [Class 40 (v)] The output stage of a receiver is arranged to be muted in the absence of a received carrier of adequate strength by means of rectified noise obtained from the output of the signal detector. On the reception of an adequate signal, the gain of the early stages is reduced so that insufficient noise is transmitted to effect muting of the output. The Figure shows the later stages of a superheterodyne receiver including a frequency modulation channel 5 and an amplitude modulation channel 6. The frequency modulation channel comprises an I.F. amplifier 7, limiter 9 and discriminator circuit including rectifiers 10 and output resistances 11, 12. The amplitude modulation channel comprises an I.F. amplifier 8, A.V.C. circuit 20 and signal detector 21 with output resistance 22. Signals are selected from one circuit or the other by a switch 25 and fed through volume control potentiometer 30 to the first audio frequency amplifier 26 A second switch 43 coupled to switch 25 allows the detected output from the two channels to be selectively applied to a control rectifier 40 through a filter 42, 41, 34 which is responsive to noise frequencies above the useful range of the receiver. The negative output voltage from resistor 33 is applied through a smoothing circuit 32, 31 as bias to amplifier 26 and is arranged to bias this valve to cut-off in the absence of a desired carrier signal thus reducing the transmission of noise. On the occurrence of a desired carrier signal, the sensitivity of channel 5 or 6 is reduced by the respective limiter 9 or A.V.C. circuit 20. This reduces the noise voltage available at 33 and so restores amplifier 26 to a condition for transmitting a signal.

Abstract: 1,215,511. Vehicle washing apparatus. J. KRONSEDER. 23 Feb., 1968 [28 Feb., 1967], No. 8842/68. Heading B7J. A truck 1, Fig. 2, movable on ground rails provides a universal joint 8 mounting an arm 7 rotatable about an axis 9 or a vertically rotatable bush 10. A lockable joint 6 connects the arm 7 with an arm 4 supporting a sleeve 3 and an electric motor 5 rotating a brush 2, and the brush may be positioned as in either A or B axial rotation and pivoting about joint 8. An electric motor 20, Fig. 4, drives the truck 1 through a wheel 23 provided with pins 22 engaging in holes in the rails 13, and the truck has rollers 11, 12, 19 which hold it to the rails. The bush 10 of the universal joint contains a plate 30 in which there is screwed a tube 31 slidably supporting an inner tube 32. The tube 32 carries a stop ring 33 at its top, and a plate 34 connected to a ram 35 so that the tube 32 may be raised against the action of a compression spring 36 adjustable by means of a nut 37. The bush 10 is helically grooved at its top, Fig. 7, and a cable 38 passes around the bush and is connected via fixed pulleys and spring pulleys to counterweights within the tube 32. When the brush is swung out by the contours of a vehicle, the bush 10 is turned and one counterweight is raised whilst the other counterweight is lowered so that one of the springs 45, 46 is tensioned to effect return swinging of the brush. Raising of the tube 32 by the ram moves both weights away from the ring 33 and prevents return movement of the brush. If the tube 32 is lowered then the ring 33 pulls both weights downwards and the universal joint 8 is prevented from turning. The arm 7 may be prevented from turning on the pivot 9 by a card and pulley arrangement (49), (50) connected to the ring 33, Fig. 5 (not shown), and a feeler (51), Fig. 1 (not shown), engages a rail and keeps the brush at the same distance from the track.

[Class 87 (ii).] Thermoplastic m a - terials are moulded by heating the solid material until it becomes plastic, injecting it under pressure into a mould and subsequently, whilst still plastic, subjecting it to a second pressing operation whilst it is hardening in a closed mould without the application of heat. The plastic mass in the space b is injected into the mould by the piston c and is then subjected to a second pressure by the plunger e which moves in a direction substantially at rightangles to that of the plunger c. The bottom plunger f is supported by a spring g so that on the application of pressure the two plungers e, f move downwards and close the inlet opening whereby any irregularities on the surface of the article are removed and subsequent polishing is rendered unnecessary. An injection pressure of about 50 atmospheres is preferably used whilst the second pressure may vary from 100 to 200 atmospheres. The injection pressure may be produced mechanically by a piston or by water, air, or like pressure. Asphalt, cellulose esters, artificial horn, artificial resins, and vulcanite are mentioned as suitable materials.

Abstract: A liquid coating composition contains a plurality of pre-formed particles of organic polymeric multi-celled foam dispersed in a liquid vehicle containing a film-forming adhesive which acts as a binder for the foam particles.  The foam particles, which are preferably pigmented, may be, for example, polyvinyl chloride or polyurethane foams.  The liquid vehicle is suitably an oil-in-water emulsion of a vulcanizable natural or synthetic rubber used in admixture with a vulcanizing agent, and is preferably colourless. The composition may also contain flock or short fibres.  The foam particles are preferably less than 3/32 of an inch long, and may be produced by mechanical shredding, or by foaming small droplets of a pre-foam plastisol to obtain spherical droplets. Shredding may be aided by incorporating salt or steam into the foam when it is polymerized, residual salt being leached out after shredding. The coatings thus produced have acoustical and thermal insulating properties, and may be decoratively useful if pigmented foam particles are used.  The binder may be an acrylic copolymer, e.g. a copolymer of methyl methacrylate with 2-ethyl-hexyl acrylate or butyl methacrylate, or a styrene/butylacrylate copolymer, or a rubber, e.g. a styrene-butadiene copolymer or neoprene.ALSO:Cloth or metal is coated with a liquid coating composition containing a plurality of preformed particles of organic polymeric multicelled foam dispersed in a liquid vehicle containing a film-forming adhesive which acts as a binder for the foam particles.
