Abstract: 1,260,861. Railway vehicle brakes. GIRLING Ltd. 24 Jan., 1969 [8 March, 1968], No. 11516/68. Heading F2E. A railway vehicle brake arrangement comprises disc and tread brakes arranged to act on the same wheel and a single actuator mechanically coupled directly to the disc brake and through the disc brake structure to the tread brake in such a manner that upon operation of the actuator the tread brake and then the disc brake are sequentially applied. Floating levers 17, 19 connected by a link 27 carry at one end disc pads and have pivot pins 16, 20 at their other ends guided in slot 18. A tread brake having a shoe 26 is coupled to lever 19 by a bellcrank 22 and levers 25, 21. The other floating lever 17 is coupled to the actuator via lever 15. On actuation the levers are moved upwards together and crank 22 rotates until the tread brake shoe 26 engages the wheel. Further upward movement of pin 16 causes lever 17 to pivot about link 27 until its pad is applied and the link 27 to move lever 19 up pivoting about pin 20 until its pad is applied. When all of the brakes are firmly engaged braking force can be applied, the forces applied by the disc brake being proportional to the thrust applied by the tread brake. The actuator 2 is coupled to link 15 and to a corresponding link of another brake arrangement on the other side of the vehicle through an automatic slack adjuster 7 having a body 8 which can abut a stop 9 adjustably mounted on a rod 10 fixed to the link 15. Drag members may support the brake shoe and maintain it in the off position, means for preventing vibration being provided.

Abstract: 675,099. Air-conditioning. KING INDUSTRIES, Ltd., S., JAMES, L. H., and JAMES, H. N. July 29, 1950 [April 29, 1949], No. 11542/49. Class 137 Air-conditioning means are enclosed in a cabinet 10 which is divided by partitions into two duct systems, shown diagrammatically in Fig. 2; air from the room being admitted at 14 for recirculation, mixed with fresh air from the inlet 28, passed through a filter 21 and a cooling element 22, to collect dust and to remove humidity. and then past heaters 23 to the fan 24 which delivers the air through the grille 12 to the room. The air may be treated with ultra-violet light at 32, and a humidifier 25 may be provided at the outlet. The fan 24 is co-axial with a fan 43 in the second duct system by which air is abstracted from the room and, with outside air, is circulated for cooling the refrigerating apparatus which operates the cooling unit 22. Room air is drawn in through the opening 14 and flows past an adjustable damper 33, through a filter 34, mixes with fresh air admitted at 36, passes over and cools the compressor 38 and motor 39 of the refrigerating apparatus, and passes through the condenser 41 of the refrigerator before being exhausted through the duct 45 by the fan 43. The arrangement of the components in the casing 10 is shown in Fig. 3, the fan motor 64 being connected to the fans 24, 43 by a coupling 63, the refrigerator unit 38, 39, being supported on cushioning-springs 53 by a base 50 which also supports the casing 10.by springs 51; and the condensate from the cooler being led by a pipe 58 to a porous body 42 which is swept by the air passing from the condenser 41 to the outlet 45. The apparatus is controlled automatically to maintain the desired temperature and humidity by manually adjustable means 47.disposed at the air inlet 14. The means 47 comprise a thermostatic switch 77 set by a knob 77a, and a humidity-responsive switch 78 set by a knob 72a, which operate through a relay 79 to switch on the heaters 23 if the air temperature falls, to bring the refrigeration apparatus 38, 39, and hence the cooler 22 into action if the temperature rises unduly, to switch on the humidifier 25, which is of the electric-steam type, when the humidity falls; or to bring into operation both the cooler 22 and the heaters 23 when the humidity needs to be reduced. A thermostatic safety switch is placed over the heaters 23 and is normally kept inoperative by the cooling effect of the air flow. If the air flow stops for any reason, the switch operates to cut off the electricity. The air delivery duct 266 is flared outwardly at the outlet, and an infra-red lamp is situated, one on each side of the flared mouth.

Abstract: 529,441. Valve-amplifying circuits. HADFIELD, B. M. April 17, 1939, No. 11581 [Class 40 (v)] Direct-coupled thermionic amplifiers for giving a balanced output from an unbalanced input comprise a pair of valves having a common cathode resistance, the anode of one valve having a D.C. connection to the grid of the second through a resistance potentiometer of such value that the gain of the first valve at the grid of the second is unity. The input is applied across a potentiometer R, G1 to the grid of a valve VI the anode of which is coupled by a potentiometer P1, P2 to the grid of a second valve V2 in such a way that the voltage swings on the two anodes are equal and opposite. Grid bias is provided by separate resistance r1, r2 in the cathode leads and by a common variable resistance r3. Resistances R1, R2 are provided in the anode circuits and a central sliding contact D connects these to the positive bus-bar, to which the valve screens (when pentode valves are used) are also connected through a resistance S. Feedback effects due to the resistances r<SP>1</SP>, r<SP>2</SP> may be reduced by closing a switch SW connecting the cathodes through a resistance r4 ; or a condenser may be connected between the cathodes for the same purpose. , Small inductance coils may be placed in the anode leads to raise the upper frequency limit response. The grid lead of the valve V2 may include a resistance G2 of such value as to neutralize interference voltages induced in the grid circuit of the first valve. Gain control may be effected by varying the series input resistance R. When the circuit is used for supplying cathode-ray tube deflecting- voltages, the deflecting-plates X are connected to the anodes, while the initial spot position is adjusted by varying the tapping adjustment D. Deflection coils may replace the anode resistances or a part thereof.

Title: Improvements in and relating to process and apparatus for separating solid granular materials
IPC: B03B5/40
Filed: 1963-03-25
Abstract: 1,012,098. Washing granular materials. K. F. TROMP. March 25, 1963, No. 11770/63. Heading B2H. Granular material, such as coal, fed into a washing tank 1 by a shoot 15 is separated according to its specific gravities by creating two or more superimposed layers of different densities in the tank by supplying at the front end of the tank at the level of the top of each layer a suspension of the density corresponding with that of the said layer, and then discharging each layer near its top to discharge the floating solids and near its bottom to discharge the sinking solids ; a common discharge opening is provided between two adjacent layers and the side walls of the tank are arranged to converge towards the discharge openings. As shown, the tank 1 operates at two different densities, a low-density suspension being supplied through perforated distribution-pipes 16, 17 and a high-density suspension through a perforated distribution pipe 18. The top layer is discharged with the aid of a paddle wheel 23 over a weir 13 on to a screen 21 and through a siphon 9 on to a screen 30 while the bottom layer at its top also discharges through the siphon and at its lower end through a hopper 7 whence it is lifted through a pipe 8 by suspension delivered from a pump 24 and discharged through a screen 26 to a sump 27; a rim 28 at the upper end of the pipe 8 is adjusted in height depending on the level in the sump 27. The suspension which falls through the screens 21, 30 is collected in a tank 22 and then returned by a pump 35 to the distribution-pipes 16, 17 and 18; the suspension which is supplied to the pipe 18 has its specific gravity raised to the correct level by thickening or, as shown, by use of a magnetic separator 36 when the suspension medium employed consists of magnetizable material. The siphon 29 has an overflow-rim 32 which is adjustable in height and controlled manually or automatically when the tank 33, which is disposed under the screen 30 and provided with an orifice plate 34, stops overflowing. In a modification, the floats may be discharged mechanically by scrapers and the heaviest products by drag conveyer or bucket wheel. In a further modification, the tank is arranged to operate at three different densities by injecting suspensions of corresponding densities and discharging through simple outlets instead of a siphon arrangement. The invention may also be embodied in the bucket-wheel trough described in Specification 804,616.
