Title: Improvements in or relating to fluid pressure braking systems
IPC: B60T11/32
Filed: 1951-04-10
Abstract: 683,364. Fluid-pressure braking systems. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. April 10, 1951 [April 14, 1950], No. 8332/51. Addition to 681,590. Class 103 (i). A fluid-pressure brake system for a tractortrailer unit is arranged to automatically isolate the service line from the tractor to the trailer should the pressure difference between two spaced points thereon exceed a certain value, so that the leakage due to breakage of lines on the trailer may not become so great as to render ineffective the brake service on the tractor. As shown in the drawing, the system includes the usual compressor 10, reservoirs 14, 16 on the tractor and 62 on the trailer, driver's control valve 40, service lines 44, 60 and emergency lines 42, 58. A ball valve 72 comprising a ball 80 raised to close same by a piston 82 is interposed in the service line on the tractor. Pipes 96 and 100 lead off two spaced points A and B in the line 44 to a valve device 88 having a time delay operating characteristic. The pipe 96 leads to a chamber 94 above a piston 92 urged upwardly by a spring 152. The pipe 100 leads by a ball-valve 102 and a passage adjustable in area by a needle valve 106 to chamber 98 below the piston 92. During normal brake operation the fall of pressure between the points A and B is insufficient to cause a pressure differential across the piston 92 large enough to depress it against the resistance of spring 152. If, however, there is severe leakage such as through a broken pipe, the piston 92 is moved down so as to engage the centre of a diaphragm 108 which, when depressed, opens a ball-valve 142. This allows air to pass from the reservoir 16 into the chamber 124 and to pass by pipe 133 to operate the piston of valve device 72 and thus isolate the defective trailer end of the service line 44. A manual valve cock 148 is inserted in a pipe-line 146, 147 between the chamber 144 above diaphragm 108 and chamber 124 so that, if desired, the ball-valve 142 may be maintained open so as to keep the valve 72 shut and thus preserve the isolation. The brake valve 40 may be such as that described in Specification 488,208, [Group XXIX].

March 19, 1935, No. 8570. [Class 40 (v)] In a superheterodyne receiver having automatic correction of tuning and a muting system, the muting is removed by a voltage produced by the error detector which is inoperative as regards action on the tuning system during manual tuning. The error detector comprises two tuned circuits 10, 11, tuned above and below the intermediate frequency, coupled to the output of the I.F. stage 4 and feeding two diodes 12, 13, the load resistances 14, 15, of which are arranged in opposing sense in the suppressor grid biassing circuit, of the automatic tuning valve 16 acting as a variable reactance across the tuned circuit of the local oscillator 3. Muting bias is applied to the low frequency pentode 6 by resistances 21 and also by resistance 22 in the suppressor grid circuit. With the signal 6 is biassed to cut-off; during manual tuning the switch 23 is closed to prevent action of the automatic tuning, the switch being interlocked with the tuning knob. As a station is tuned in, energization of circuit 10 or 11 by a station of adequate strength causes a rectified p.d. across resistance 14 or 15 which diminishes the negative bias on the suppressor grid of 6 and removes the muting. The switch 23 is then opened and the final tuning is automatic. Specifications 407,057 and 443,423 are referred to.
