Filed: 1935-04-06
Abstract: 431,930. Road - traffic signals on vehicles. JOHNSON, J. B., 17, Selbourne Street, and WOOD, F., The Gables, Feniscliffe, both in Blackburn. April 6, 1935, No. 10666. [Class 118 (ii)] Direction arrows at the front and rear of a vehicle are rotated by means of a handle through mechanical gearing to point to left or right to indicate a proposed turn, are locked in indicating position and are released by movement of the steering mechanism to allow them to be spring-returned to normal. The arrows are illuminated by lamps which are switched on automatically when the arrows are in signalling position and may also be switched on by a hand switch. As shown, when the handle 17 is turned to left or right, the shaft 1 is rotated by gearing 11, 12 to rotate arrows 4, 5 at the front and rear of the vehicles, the shaft being held in indicating position by projection 20 or 21 engaging the recess in arm 22 and the lamps in the arrows being switched on by contact 44 or 45 engaging contact blade 50.

Title: Improvements in or relating to electrical measuring instruments
IPC: G01R23/00
Filed: 1932-04-14
Abstract: 399,867. Frequency measurements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, PARKIN, T. D., The Haven, Mill Lane, Broomfield, near Chelmsford, and WEBB, K. S., 8, Effingham House, Larkhall Estate, London. April 14, 1932, No. 10747. [Class 37.] A wave meter comprises a calibrated variably tunable input circuit connected to the input terminals of a thermionic valve the internal impedance of which forms one arm of a Wheatstone bridge. As shown in Fig. 1, a calibrated tuned circuit including an inductance L and variable condenser C is coupled through a condenser K to the control grid of a screened grid valve V. The other end of the tuned circuit is connected to the cathode of the valve V, a resistance R being connected between the grid and cathode. The internal impedance of the valve V forms one arm of a Wheatstone bridge, of which a resistance Rf<1> forms a second arm and a potentiometer resistance Rv<1> forms the other two arms. In the diagonal of the bridge is connected a milliammeter MA protected by a key K1 and shunt resistance R1. The bridge is balanced when no potential is applied to the grid of the valve V. When a signal frequency to be measured is applied to the grid the impedance of the valve changes, the bridge is unbalanced, and a reading is given on the instrument MA. In order to obtain greater sensitivity than by making observations at the maximum point A, Fig. 4, of the resonance curve, a detuning condenser Ca may be connected in parallel with the main condenser C by a key K2. The resonance curve is thereby shifted to the position shown in dotted lines. By varying the setting of the main condenser C until no change occurs when the key K2 is depressed, observation is effected at the point X of maximum slope of the resonance curve. The moving vanes of the condensers C, Ca are mounted on a common shaft S and electrically connected, the fixed vanes being insulated. Alternatively the fixed vanes may be connected and the moving vanes normally insulated, but adapted to be connected by a key. In order to provide a number of ranges the condenser C may be subdivided into two portions, a number of co-operating plug-in inductances being arranged to short-circuit one or other portion or connect both portions in parallel, as described in Specification 352,929. In this case the detuning condenser Ca is similarly subdivided and the key K2 is so arranged that the portions are connected similarly to those of the main condenser. Detuning inductances may be employed instead of detuning condensers. A single detuning inductance may be arranged to cooperate with a number of main inductances to give a number of operating ranges, and may consist of a single fixed turn surrounding the main inductance and adapted to be shortcircuited by a key. The frequency to be measured may be applied to the calibrated tuned circuit by means of a small aperiodic circuit coupled thereto, the whole instrument and the leads connecting the aperiodic coil being screened.

An electric motor driving a lubricating oil pump, e.g. in a motor vehicle, is stopped after a predetermined number of revolutions by a camoperated switch geared to the motor shaft. Provided a switch 39, e.g. the vehicle ignition switch, is closed the motor 10 is started by the momentary closing of either 41, e.g. contacts in a mileage recorder, or manual switch 40. An indicator lamp 44 lights up until an oil pressure switch 37 opens, the motor continuing to run until contacts 28 are opened by the motor-driven cam 27. The circuit provides that the motor completes its cycle even if the switch 39 is opened, that the cycle will not be repeated in the event of the starting switch 40 or 41 remaining closed, and that, if a desired oil pressure is not reached, the lamp 44 remains on but the motor will not restart until opening of the switch 39 resets the circuits to the initial condition shown. The motor 10, the pump (not shown), the cam switch 27, 28 and electromagnetic switches 32, 33 are all contained in a single unit (Figs. 1 and 2, not shown).
