Abstract: 1,274,487. Measuring angles electrically. JUNGNER INSTRUMENT A.B. July 8, 1969 [July 19, 1968], No.34269/69. Heading G1N. A system for measuring angular displacement comprises an angular resolver having two-phase stator windings fed with alternating voltages V S1 , V S2  in phase quadrature, that V S1  also being fed to a reference pulse unit 7 to generate reference pulses at zero transitions of V S1 , and a singlephase rotor winding the voltage induced in which is shifted in phase by # radians from V S1 , which phase shift represents the angular diaplacement of the rotor relative to the stator, and is fed to a pulse signal unit 6 to generate signal pulses for positive half-cycles of the rotor voltage. The signal and reference pulses are fed to a detector circuit 8 which produces a measuring pulse only when a reference pulse level "1" and a signal pulse level "0" are coincident. Thus the duration of the measuring pulse is proportional to the angular displacement of the rotor. The system is applied to indicating the angular disposition of valves in a ship's fuel tanks. Visual signals may be given of open and closed dispositions of the valves, where an unlit lamp indicates valve closed, intermittent lighting indicates partly open and a continuously lit lamp indicates valve fully open.

Title: Improvements in automatic brake control means for vehicles
IPC: B60T7/12
Filed: 1961-09-25
Abstract: 929,106. Automatic brake control. BENDIX CORPORATION. Sept. 25, 1961 [Nov. 7, 1960], No. 34310/61. Class 103 (1). [Also in Group XXXI] A vehicle brake-actuating mechanism is provided with biasing means in the form of a spring A for applying the brakes and a fluidpressure operated motor B for releasing the brakes; a solenoid operated valve C controls the motor B and is adapted to be automatically set to permit communication of the fluid pressure motor C with a fluid pressure source, such as vacuum reservoir 32 supplied with vacuum from engine inlet manifold 14, by a device responsive to an emergency condition. Fig. 1 shows the arrangements of a brake on a vehicle wherein the spring A is extended and brake-actuating lever 16 is moved to its inoperative position where it is returned into abutment with stop 22 on lever 18. The solenoid operated valve C is actuated by means of a control limit switch 44 positioned under the vehicle operator's seat such that the weight of the operator upon seat 42 operates the limit switch and should the operator fall from the seat the switch 44 will open and de-energize the solenoid-operated valve C to close off the vacuum connection to the motor B and permit spring A to actuate the brake pedal lever 16 and thereby apply the brakes of the vehicle through an hydraulic master cylinder 10. The invention may also be applied to a vehicle having a central hydraulic system wherein an hydraulic reservoir will replace the vacuum reservoir 32 and a check valve is provided between the pump and the accumulator to prevent loss from the latter during stoppage of the pump. In such a case an hydraulicallyactuated pressure switch supplied with pressure from the pump may be used to de-energize the solenoid valve C on pressure failure so as to apply the brakes when the propelling engine stops. Fig. 3 shows an arrangement for use in a driverless vehicle wherein the brakes are applied when the vehicle departs from its intended track such as a painted strip 58 which is applied to the surface over which the vehicle operates. A light positioned on the vehicle supplies reflected light from the strip to a photoelectric cell 60 which actuates a relay switch connected to the solenoid valve C. So long as the vehicle passes over the intended track the brakes of the vehicle will be released but should the vehicle depart from the intended track over the painted strip 58 insufficient light reaches the photo-cell 60 to energize the solenoid 42 and the brakes of the vehicle are applied. The present invention can also be used in systems where the vehicle is remotely controlled either by radar or by engagement with the wire on the floor over which the vehicle travels. The ignition switch of the automotive vehicle may also be substituted for the switch 44 so that the system automatically applies the brakes of the vehicle when the ignition switch is turned off.

Title: Improvements in or relating to subscribers line circuits for use in telephone systems
Inventor: ALLEN LESLIE JOHN
IPC: H04Q3/52
Filed: 1954-11-30
Abstract: 811,994. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Oct. 27, 1955 [Nov. 30, 1954], No. 34604/54. Class40 (4). A subscriber's line circuit, having a resistor over which the calling subscriber's loop develops a calling potential, comprises a transistor responsive to this potential. A further transistor is used for repeating ringing current to the line. Completion of the calling subscriber's loop lowers the potential across resistor R1  thereby rendering transistor TX2 conducting. The consequent rise in potential of the point X enables tube VK11. Tens and units scanning pulses are applied to leads TL, UL, as described in Specification 735,635 and when VK1 is enabled, units pulses are passed to tube VK12 which also fires when the appropriate tens pulse is present on lead TL. The resulting pulse is fed to lead LFS to stop the scanning. The striking of VK12 also fires tube VK16 in a preselected link circuit, the rise in cathode potential thereof striking VG4. A voice circuit is now established from the link to the calling subscriber by means not shown and V.F. tone is passed via rectifier MR, which is rendered conducting by the rise in potential of point X, gas diode VG 4 and tube VK16. The link thereupon reverts dial tone. During dial interruptions transistor TX2 becomes non- conducting and the potential of point X falls to cut off rectifier MR, so that the dial impulses are repeated to the link as interruptions of the V.F. tone. In the case where the subscriber is to be rung, tube VK18 is fired, thereby firing the triggering gap of tube VK10. Intermittent current IR of ringing frequency is applied to the anode of VK10 which thus fires on alternate half-cycles, the resulting pulses derived from the cathode resistor being applied to the base of transistor TX1 to cause it to conduct. The resulting collector current pulses are fed to line via transformer TR1 as ringing current. When the called subscriber answers, the rise in potential across R2 cuts of the transistor TX1 to stop the ringing current.

Title: Improvements in or relating to sound records and systems for recording the same
IPC: G11B7/00
Filed: 1931-12-16
Abstract: 394,328. Optical sound-recording. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, and ROUND, H. J., Westfield, Muswell Hill, both in London. Dec. 16, 1931, No. 34894. [Class 40 (ii).] A process for recording sound is characterized in that the sound record is divided between a plurality of component tracks of fixed predetermined widths in such manner that sound amplitudes exceeding a predetermined amount are recorded in part upon one track and in part upon another. In the system shown, one or more microphones (not shown) are connected to. an amplifier, the output of which actuates, through a transformer T, two oscillographs W<1>, W2 which, when operative, record two sound tracks T<1>, T<2> side-by-side on a film F. The oscillograph windings are arranged to be energized in such manner that only the oscillograph W<1> is effective to record sound below a certain amplitude, whilst both oscillographs operate when the sound exceeds that predetermined amplitude, the record then being made on the two tracks T<1>, T<2> together. Current through the .device W<1> is reduced correspondingly with that passing through the device W<2> when both are in operation, so that the total volume recorded is correct. The switching over from one to two tracks may be effected automatically by providing relays R<1>, R<2> which are operated by rectified and smoothed audio-currents when the predetermined amplitude is reached.- The purpose of the relay R<2> is to control a shutter K which normally interrupts light from the mirror of the oscillograph W<2>. The apparatus may be modified to record on more than two tracks, the third track being employed when a second amplitude limit is reached, and so on. The tracks may be of either equal or unequal widths. Instead of automatically switching over from one to a plurality of tracks, manual means may be employed ; for this purpose, the operator may be guided by a suitable meter indicating the microphone output. A multi-track film made in accordance with the invention may be derived from a single track record made in the ordinary manner.
