Abstract: 769,094. Coating cables. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Jan. 19,1955 [Jan. 20, 1954], No. 1712/54. Class 140. A marking head is fitted with one or more centrifugally operated valves for controlling the admission of compressed air or other gaseous pressure medium to one or more marking fluid reservoirs to exert pressure on the marking fluid to feed it to one or more applicators during rotation of the head at or above a given speed. As shown; a bracket 2 supports a spindle 1 having a central bore 3 through which the cable to be striped passes. Mounted to rotate on the spindle 1 is a tubular member 6 having a driving gear 7. The bore 3 passes upwardly to a tube 9 extending into an aperture in a container 8 mounted on the member 6 and housing reservoirs 10 and 11 for marking fluid. Compressed air is supplied to the reservoir from an opening 33 in the bracket 2 leading to passages 34, 35 controlled by a centrifugally operated valve 36 through passages 43, 44, and flexible tubing to a passage in a cover-plate 12 opening into the reservoirs. Two or more valves 36 for supplying compressed air to the reservoirs may be provided. The flexible tubing may be dispensed with and a passage made in the container 8. The valves 36 are operated by weighted levers 40 which open the valves at a predetermined speed of the tubular member 6. An air vent 51 is provided. The marking fluid is driven by the compressed air along pipes 25 to a marking applicator 17 mounted above the cover-plate 12 and having the number of outlets according to the number of stripes desired. Several applicators may be combined, one being mounted above the other. Each reservoir may be divided into compartments each containing a pipe conveying marking fluid to the applicator. A guard 60 surrounds the members 6 and 8. To prevent operating the device when the cover-plate is not secured, a circuit breaker controlling the driving motor is opened by a relay in a circuit with the securing bolts for the cover-plate. Compressed air may be supplied to reservoirs at different pressures to supply fluids having different viscosities.

Abstract: 524,033. Control of D.C. motors. STOTHERT & PITT, Ltd., and COOMBES, R. W. J. Jan. 19, 1939, No. 1948. [Class 38 (iii)] Non-regenerative braking ; field control. - A winch motor 2, having a shunt field winding 3 and main and auxiliary series field windings 4, 5, is controlled by a system including two relays 10, 12 the former operating when the controller is in a full speed lowering position and the load is less than a predetermined value, to reduce the series field upon the attainment of a predetermined speed, and the latter operating when the controller is in a lowering position and the load exceeds a lower predetermined value to establish a dynamic braking circuit. The relay 10 is connected across the motor armature in series with contacts 20 closed when the controller is in its full speed lowering position, and contacts 21 closed unless the load is in excess of the higher predetermined value. This relay 10 operates to energize the main field 4 which opposes the auxiliary field 5. The relay 12 is energized from the mains in series with contacts 26 closed in all lowering positions of the controller, and contacts 25 closed when the load is in excess of the lower predetermined value. With zero load,'the series field is weakened when a predetermined speed is reached at the high speed lowering position of the controller. For loads between say “ -1 ton, the dynamic braking circuit may be established with a connection from the supply through the auxiliary field 5 and a resistance 8 to the armature. For loads in excess of a ton, the contacts 11 of the relay 10 are not closed, and the main series field 4 remains fully effective for braking. When the controller is returned from its full " on " position, the relay 10 remains connected for an interval over contacts 27.

Title: Improvements in or relating to electrical signalling systems
IPC: H04N5/202
Filed: 1935-01-21
Abstract: 437,997. Automatic volume control. ETABLISSEMENTS E. BELIN, 56, Faubourg St. Honore, Paris.-(Assignees of Constant, R. ; 296, Avenue Paul Doumer, La Malmaison, Rueil, France. Jan. 21, 1935, No. 2010. Convention date, Jan. 19, 1934. [Class 40 (iv)] [See also Group XL] Automatic variation of signal volume in accordance with signal level is effected by connecting the anode - cathode path of one or more thermionic valves in shunt of the signal circuit, the signal voltage being the sole source of anode potential. Compression or expansion of the volume range is effected according to bias applied to the grid of the valves. The arrangement shown in Fig. 3 effects compression since the impedance of the valves decreases as signal level increases. In the modification shown in Fig. 4, a transformer E has a third winding shunted by a pair of valves in push-pull, whereas in Fig. 5 (not shown) the push-pull shunt is applied across the secondary of a transformer in the transmission circuit. The shunt may also be applied at an intervalve coupling. In the expansion arrangement shown in Fig. 7, increase in signal level increases anode current which increases the valve impedance due to increase of biassing potential over resistance R. The compression arrangements are particularly applicable to picture telegraph transmission for compensating the relatively weak response of a photo-electric cell to dark shades, whereas the expansion arrangement, Fig. 7, may be used when the picture currents are inverted at the transmitter.

Title: Improvements in Electrical-Discharge-Gap Apparatus.
IPC: H01T4/14
Filed: 1919-01-28
Abstract: 123,064. British Westinghouse Electric & Manufacturing Co., (Assignees of Allcutt, C. T.). Feb. 8, 1918, [Convention date]. Condensers.-To allow high-frequency currents such as switching surges and lightning disturbances to pass through electric discharge-gap apparatus at or below the normal voltage, one or more auxiliary electrodes are arranged in the main discharge gap and are connected to the main arcing- horns through impedances of dissimilar character; the relative impedances of these connexions at normal frequency are proportional to the distances of the auxiliary electrodes from the horns, so as not to disturb the main gap under ordinary conditions. On a disturbance of high frequency, the impedances become unbalanced, and the gap between the auxiliary electrode and one horn is broken down thereby starting an arc across the main gap. In the example shown in Fig. 8, the horn 12 is mounted on an insulator 28 carried by a pillar formed of alternate insulators 30 and conductors 31. The auxiliary electrode 15 lies between rounded terminals 32, 34 and is connected to the middle of the pillar, which thus forms two condensers. Rods 40, 41 electrically connect the lower condenser to the support 45 for the terminal 34, the support 45, pin 41, and insulator 33 acting as a condenser. The horn 36 carried by the insulator 35 is connected to the support 45 through the ohmic resistance 38 and thence to earth through the electrolytic device 39.

Filed: 1944-02-08
Abstract: 576,778. Optical sound recording and reproduction. BUCKLE, C. C. Feb. 8, 1944, No. 2278. [Class 40 (ii)] [Also in Group XX] The sound track on a sound-film is in the form of a series of wavy lines. The record may be made in a system including light source 1, Fig. 3, lens 1a, oscillograph mirror 3, and slotted mask 4, producing point images on the track 5 which move in response to currents in the oscillograph. In reproduction, the track 10, Fig. 4, is scanned obliquely, for example, by imaging the trace formed on the screen of a cathode-ray oscillograph 6 on the track, the light passing through the track falling on a photoelectric cell 9. The output obtained from the cell is a frequency-modulated carrier wave the speech modulation of which can be detected in the usual way by use of a frequency discriminator circuit. The frequency of the unmodulated carrier, which is generated when the track lines are straight, may be of the order of 1.5 megacycle for example. The track may also be scanned by a beam of light projected through apertures in a scanning disc, or the film image may be projected onto a mosaic screen which is scanned by a cathode-ray beam. Where cathode-ray scanning is employed in reproduction, film flutter in recording or reproduction may be corrected for by making a record of a constant frequency tone in the ordinary way, this record being reproduced to afford an output for controlling the position of the cathoderay trace to effect the necessary correction.
