Title: Improvements in Telegraphy and Apparatus therefor.
Inventor: FULLER ALGERNON CLEMENT
IPC: H04M11/06
Filed: 1916-02-16
Abstract: 124,504. Fuller, A. C. Feb. 16, 1916. Simultaneous telegraphy and telephony; telegraph and telephone calling apparatus.-In a combined telegraph and telephone system the telegraph signal currents are received as impulses in a telephone receiver; an inductance is placed between the line and the signal current interrupter, and a condenser is connected to a point between the inductance and the interrupter and to earth in order that the interruptions may not affect the current in the line. A condenser is connected to earth on the line side of the inductance to provide a free path for the telephone current. The inductance placed between the line and the interrupter prevents induced currents on the line from affecting the telephonic telegraph receiver; while the effects of stray earth currents are avoided by impressing, by means of a potentiometer and a reversing switch, a potential equal and opposite to that of the stray current. When calling, an extra battery is inserted in the circuit of the primary of the telephone transformer and the interrupter. The arrangement at each station on the line is shown in Fig. 3, and is connected to line at the terminal a and to earth at the terminal b. Telephonic currents pass through the receiver m, the secondary winding k of a transformer l, and the condenser e to earth; while telegraph signal currents pass through an inductance d, interrupter h<1>, and a telephone receiver i to earth. A condenser f is connected to a point between the inductance d and the interrupter h<1>, and to earth, so that, when the interrupter breaks the signal current, the condenser f is charged, and, when the interrupter again makes the signal circuit, the condenser f is discharged to augment the normal signalling current. To eliminate the effects of stray currents in the receiver i, a battery v', a reversing.switch w<1>, w<2>, and a potentiometer n are provided, by means of which a potential equal and opposite to that of the stray current is applied to the line. When the station is receiving messages, a switch-arm t is placed in contact with a terminal t<1>, and, when a station is calling, the switch-arm t is placed in contact with a terminal t<2> and a push q is depressed thereby connecting an auxiliary battery s in series with the main battery v, interrupter h' and the primary winding n of the transformer l.

Abstract: 1512935 Inertia-controlled brake valves TOYOTA JIDOSHA KOGYO KK 24 Jan 1977 [12 July 1976] 02857/77 Heading F2F Twin circuit inertia-controlled brake valve has first and second inlets 31A, 31B, and corresponding outlets 32A, 32B. At a predetermined deceleration, balls 50A, 50B contact valve seats 51A, 51B to isolate each outlet from its respective inlet. If a line fails downstream of outlet 32A, the pressure in the other circuit, at V 2 , urges a differential piston 60A to the right to press the ball 50A against valve seat 51A, so isolating the failed sections. A further inlet 34 is connected to the same source as the inlet 31A, so that on failure of a line downstream of outlet 32B, the ball 50B is similarly pressed against seat 51B by the differential piston 60B. The balls may be spring-loaded. In a modification (Fig. 2, not shown) one differential piston is located around the hollow stem of the piston 60A and another around a tube containing the bore 700a. After the balls 50A, 50B have closed on to valve seats 51A, 51B, these pistons have the effect of transmitting to the outlets 32A, 32B, proportionate increases in the inlet pressures.

Abstract: 1504401 Television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 Jan 1975 [30 Jan 1974] 3402/75 Heading H4F A black and white test pattern a, Fig. 1, is used to obtain registration of three rasters LG, LR, LB in a colour television camera which comprises three pick up tubes 1, 2, 3. The resulting component signals derived from each raster scan are sampled at predetermined points Mb, Mw, Mh, Mv, Ms and compared against reference values, adjustments to the registration and peak to peak values of the signals being effected in accordance therewith. The signal from raster LG is processed first. The signal at Mb is compared with a zero or earth potential reference, adjustments being made to a black level clamping circuit as appropriate. The signal at Mu is compared with a 1 volt peak white level reference and appropriate adjustments are made to a diaphragm aperture of the camera. The signal at Mh is compared with a 0À5 volt 50% grey level reference and an appropriate horizontal shift of the raster is effected if necessary. The signal at Mv is also compared with the 0À5 volt reference but in this case a vertical raster shift is effected in accordance therewith. Finally for the raster LG the signal at Ms is compared with the 0À5 volt reference and a skew correction is effected if necessary. This process is repeated for each of the remaining rasters LR, LB, differing only that the peak white level corrections are effected by means of respective variable gain amplifiers. In a second embodiment all corrections are performed simultaneously. The process is carried out with the test pattern in the ambient light of the scene to be televised so that the correct peak-to-peak adjustment of the resulting video signal is automatically performed.
