Title: Process allowing the conversion of a high frequency current modulated at low frequency into very short current impulses, and particularly applicable to direct-reading radiogoniometers and to the transmission of measurements
IPC: G01S1/02
Filed: 1935-01-05
Abstract: 435,674. Electric signalling systems. BERTRAND, A., and PARISIER, M., 17, Rue Desnouettes, Paris. Jan. 5, 1935, No. 415. Convention date, Jan. 5, 1934. [Class 40 (i)] [See also Group XL] In direct-reading radio-goniometer systems for transmission to a distance of the indications of measuring apparatus involving a stroboscopic effect, the periodic variations of current due to rotation of the receiving member are converted into sharp pulses by rectifying and passing through a resistance in the grid circuit of a triode. By this means very brief flashes of the neon lamp of the stroboscopic apparatus can be obtained. Fig. 1 shows a radiogoniometer comprising a frame aerial 1 rotated conjointly with the pointer 2 associated with a transparent dial 3. The current maxima produce flashes in the neon tube 4 behind the dial 3 and the direction of the transmitting station is shown by the apparently stationary pointer 2. According to the invention the received currents modulated by the rotation frequency of the receiving member are rectified by a double diode Al, Fig. 5, the resulting voltage drop across the common load resistance R increasing the negative grid bias of the triode A2 until only the peaks of the pulsations alpha, o, #, Fig. 4, produce sharp pulses i of anode current. The valves A1, A2 may be combined as a double-diode triode, and the voltage across resistance R may also be used for automatic gain control, Figs. 6 and 7, (not shown). Fig. 8 shows an arrangement for transmitting the indications of a meter 6 to a distance, in which the meter pointer 5 carries a coil 7, fed with high frequency currents from a source 8. The currents periodically induced in a rotating search coil 9 from the coil 7 are amplified at 10 and passed to the receiving apparatus, for example, over a line 12. The receiving system 11 is constituted by a disc rotating synchronously with the coil 9 and carrying a lamp 13 fed from circuits such as described.

Straight-bar machines.-Rotary-rib and like frames are provided with pattern-controlled mechanism for automatically making patterned tuck-work and royal rib and for draw or slip courses, i.e. performing the ordinary knitting movements while withholding yarn. Notched tuck-pressers a<2> are mounted in independently adjustable and changeable sections on a slide a<4> carried by an oscillating member a.

The disk g<7> is mounted on the member a and is operated at the forward movement of the pressers by a pawl g<15> the pivot of which is held stationary by a strut g<16>. The pawl may be held out of action by means of link-work h, h<1>, h<2>, h<4> operated from screws b<2> on the sides of the welting-wheel b. The royal-rib and draw-course tackle is controlled through levers j, j<1> by camblocks on a disk i<14> intermittently advanced through connexions i<10>, i<6> from a cam i<9> on the top cam shaft C. The bell-crank i<6> can be put out of action at intervals by an arm i<3> the upper notched end i<4> of which engages a pin i<5> when pushed forward by connexions i, r under control of the wheel b.

Title: Compact electric apparatus powered by solar cells,in particular a solar watch
Inventor: GANTER WOLFGANG
IPC: H02J7/35
Filed: 1990-10-18
Abstract: A small electric device powered by solar cells and by a capacitive charge storage element has stable actuation assured during startup with an as yet uncharged capacitor. Startup problems are avoided by control of the power supply with a threshold value circuit that allows power to be supplied to device components when the components' minimum actuating voltage level has been attained at the capacitor. A deactuating voltage value of the threshold value circuit that is lower than the actuating voltage level prevents interruptions of operation similar to relaxation oscillation behavior due to temporarily increased actuating power requirements by causing deactivation of the components only if the capacitor voltage has dropped below a predetermined operational minimum. In this manner additional functions (such as radio watches with automatic hands setting devices or directional antennas, or ornamental pendulums or alarm or striking watches) which have components with higher acutating power requirements may be supplied without batteries by solar cells without having to overdimension the storage capacitor for the high startup load and thereby unnecessarily delay actuation of the device upon the exposure to radiation of the solar cells.
