Abstract: 756,431. Supply systems for space-discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 8, 1952 [Dec. 8, 1951], No. 31066/52. Class 38 (4). A starting and operating circuit for a pair of gaseous electric discharge tubes, e.g. fluorescent lamps D1, D2, comprises a transformer 11 having a primary winding P with connections to an A.C. source, a high leakage reactance secondary winding S and a low current capacity auxiliary winding A, a ballast capacitor C1, a leading current lamp operating circuit comprising in series at least the secondary winding S, the ballast capacitor C1 and connections for including both lamps, a coupling capacitor C2, and a leading current lamp starting loop circuit comprising connections for including only one D1 of the lamps both of the capacitors C1, C2 and all the windings in series, all the windings being in voltage aiding relationship within the loop circuit. The coupling capacitor C2 is to prevent the circulation of direct current by either lamp acting as a rectifier on failure of one electrode thereof, and thereby permits the low current capacity of the auxiliary winding A. In Figs. la and 3a, not shown, the operating circuit includes the primary winding P which is arranged in such circuit in voltage aiding relationship with the secondary winding S. To reduce shock hazard, as shown, one, or in Fig. 3a, both, connections from the primary winding P to the source terminals 15, 16 are made through contact pairs 17, 18 and 20, 21, each short circuited by one of the respective contact pins 2<SP>1</SP> and 2 of each lamp, whereby removal of either lamp open-circuits or disconnects respectively the primary winding from the source. In Fig. 1a a magnetic shunt provides a loose coupling between the primary and auxiliary windings.

Title: Monitoring device for anti-lock control system
IPC: B60T8/82
Filed: 1973-06-29
Abstract: 1397033 Antiskid braking systems TELDIX GmbH 29 June 1973 [30 June 1972] 31146/73 Heading F2F In a device 14 for monitoring an antiskid brake control system the duration of response of a brake pressure controlling element such as a valve is monitored and a signal generated if the said duration exceeds a predetermined time limit, the signal being received by means which prevents the system being made ineffective if in addition a slip signal is received from a wheel or wheel group. Response durations of valves 15, 16 are monitored by timing circuits in device 14 via lines 24, 25 and if the predetermined time limits are exceeded the energizing current for a relay 20, which is normally energized via the vehicle ignition switch, is blocked unless signals received from wheel sensors 3, 4 justify an extension of the limit and the valves which are controlled by logic circuitry 23 via gates 21, 22 are returned to their starting position since contacts 20<SP>1</SP> of relay 20 are opened. A warning device such as a lamp 26 indicates that the control has beeen rendered ineffective. If an acceleration signal is present the monitoring is ineffective and the non-driven wheels are separately controlled. In another embodiment, Fig. 4, rotary speed signals from the two front wheels and from the driven axle are fed to a logic circuit 110 and control signals for valve arrangements 112-114 are obtained in circuit 110 using a slip measurement and/or rotary deceleration and/or acceleration. The response time of valves 112, 114 is monitored by timing circuits 115-117. Particular road conditions can cause larger response time as well as a fault so that the vehicle brakes are actuated for a further time in pulsed fashion until things become normal or the extension time expires, a timing element 127 responding through an OR gate 124 to cause monitoring device 125 to respond and switch off the control and/or generate a warning.

Abstract: 732,528. Friction ratchet jacks. Lever loadhandling machines. UTZ, H. Nov. 11, 1953 [Nov. 11, 1952], No. 31278/53. Class 78 (3). A friction ratchet lifting mechanism has, in addition to the normal lifting plate C and holding plate D, a returning plate E which permits the load-supporting member B to be lowered, step by step, on the column A. Member B is lifted in the usual manner by oscillation of lever P, whilst lowering is effected by oscillation of a further lever F pivoted to plate E at R and connected to plate D by a link G. With the member B held in its raised position by the tilted plate D engaging the column A, initial anticlockwise movement of lever F takes place about pivot L and tilts plate E to cause it to engage the column, whereafter further movement of the lever in the same direction takes place about pivot R so releasing plate D and allowing this plate and member B to move downwardly. Movement of lever F in the reverse direction first locks plate D to the column and then releases plate E, so allowing it to be returned to its released position by a spring Q. Anti-clockwise movement of lever F is limited by the engagement of a stop M thereon with link G.
