Title: Improvements in and relating to driver's brake valves for railway trains, engine cars, and the like
IPC: B60T15/04
Filed: 1922-02-09
Abstract: 178,074. Drolshammer, I. O. G. Feb 9, 1922. Fluid-pressure.-A driver's valve for a fluid pressure brakes system comprises a pressure-regulator a, Fig. 1, and a controlling-valve c. The regulator c is set to maintain the desired pressure by the lever d, and the valve e is rocked by moving the same lever d in a plane at rightangles. The valve e< >has< >two channels o. z, Fig. 2, giving two open positions and one closed position. Figs. 5 and 6 show a construction of regulator, the controlling-valve c being mounted. on the regulator housing a, and both valves being operated by a lever d. The pressure regulator comprises a piston g sliding on a rod b within a ported sleeve l. The rod b carries an abutment k for a spring i, and a piston h, and the valve g is under the influence of the spring i and of pressure fluid passing through a channel x to its upper end. The rod b is moved to set the valve by the handle d acting through the connections t, s, r. The handle d has a locking-pin 7 engaging a rack 6, and adjustable stop pins 9, 10 may be provided. The handle d and its connections are mounted on a rotary head 3, a segmental rack 5 on which is arranged to engage with a spurwheel 1 on the spindle of the controlling-valve e. The handle d thus serves to control the valve e and to set the pressure regulator. The inlet chamber v of the pressure regulator connects with the outlet of the valve c, and the inlet ports are controlled by the piston g. The ports o in the sleeve permit of discharge to the outlet connection c, and ports p are uncovered upon excessive downward movement of the piston g in order to reduce the pressure in the train-pipe connected with the outlet c. A stop q is provided on the rod b and arranged to move the piston g positively in the event of extreme upward movement of the handle d. Upon extreme downward movement of the handle d, the piston h contacts with the piston g. In this way the pressure in the train-pipe may be increased or reduced suddenly. The area of the inlet and outlet openings to the driver's valve may be adjusted by hand in accordance with the nature ot the train to be braked.

Abstract: 854,944. Clothes driers. ROBERTSHAWFULTON CONTROLS CO. Feb. 4, 1959 [March 28, 1958], No. 3984/59. Class 34(2) In a tumbler drier having a closed air circulation system in which the hot moistuure-laden exhaust air passes through a curtain of cooling condenser water, the electric heater 34, Fig. 1, in the recirculating duct 26 is controlled by means within a box 66 dependent upon the temperature differential between the incoming condenser water and the discharging water and lint mixture. Temperature sensing element 88, 134 transmit temperature changes via expanding and contracting liquid in piping 86, 132 respectively, to elements 82, 126, the accumulative motion of which causes actuation of a lever 186 which, through a further lever 182 and a spring-loaded apertured plate 170, effects snap-over action of a spring-loaded arm 156 carrying a contact 146 between contacts 142, 144. A timer 196 is used to control the drier such that on starting up the switches 198, 200, 202, 204 are made and contacts 146, 144 are together. The heater 34, recirculation fan 32 and drum motor 18 are thus energized until a temperature difference exists between the elements 88, 134 when the elements 82, 126 combine to move the lever 186 to effect snap-over of the arm 156 such that contacts 146, 142 are closed. Once sufficient time has elapsed to ensure stable drying conditions the timer opens the switch 198 but the heater remains energized through the closed contacts 146, 142. The switch 202 opens next to break the timer circuit so stopping the latter. Drying continues until the temperature difference between the elements 88, 134 drops to a predetermined value when the contacts 142, 146 are opened and 144, 146 closed. The heater is then de-energized but the timer restarts until it breaks switches 200, 204 to de-energize the fan, the drum motor and itself to thus switch off the drier. The actuating temperature difference between the sensing elements may be predetermined by a pre-set knob 102.

Filed: 1953-02-16
Abstract: 767,396. Frequency changing circuits. PHILCO CORPORATION. Feb. 16. 1953 [Feb. 14, 1952], No. 4261/53. Class 40(6) A circuit for mixing a first frequency F1 with a relatively high frequency F2 comprises a velocity modulation type valve to which both frequencies are applied and an output resonator from which is derived a frequency equal to F2 Œ nF1 (where n is an integer) and a frequency F2 which is used to provide the first frequency input. A modulated intermediate frequency signal (F1) from the intermediate frequency amplifier of a radio repeater is applied to the grid 22 of a Klyston valve biased so that current-flows only during a small portion of the intermediate frequency cycle. A high frequency (F2) is applied to the first resonator and the second resonator is tuned to a sum or difference frequency (F2ŒF1) which is extracted through a filter 54. The transmission line 52 is resonant at the frequency F1 and serves, together with the filter, to reflect a high impedance into the resonator at this frequency. Energy can therefore be extracted at this frequency and passed through a temperature compensated stabilizing resonator 56 to supply the high frequency input. The stabilizing resonator may be omitted or replaced by a bridge circuit which is unbalanced only at the frequency F2, and the frequency F1 may - be applied to the cathode instead of the grid (Fig. 4 not shown). Specification 675,952 is referred to.
