Title: Improvements in pyrotechnic devices, and electrical dischargers for use therewith
Inventor: SCHERMULY ALFRED JAMES
IPC: F41A19/69
Filed: 1958-11-27
Abstract: 863,477. Pyrotechnic devices. SHERMULY PISTOL ROCKET APPARATUS Ltd. Nov. 26,1959 [Nov. 27, 1958], No. 38270/58. Class 9(2). A pyrotechnic device 1 comprises a tubular casing 3 of electrically conductive light alloy, an explosive charge 10, a plug 5 of electrically insulating synthetic resin and an electrical contact ring 6 of light alloy mounted on the plug and axially spaced from the end of the casing. The outer surface of the casing is coated with a layer 22 of electrically insulating material e.g. stove enamelling, except for a band 23, which forms the second electrical contact of the device. Each contact 6, 23, is respectively aligned with a member 25 of the discharge tube, Fig. 2 (not shown), prior to discharge. An electrical igniter 13, adjacent a delay fuze 12, is connected between the casing and the contact ring 6 by leads 16 and 14 respectively. Circumferential grooves 4 and 7 in the plug 5 secure the ends of the casing and contact ring respectively and the shoulder 8 of the plug ensures electrical insulation between them. A synthetic resin closing cap 20, with a pressure relieving aperture 21 therethrough, is screwed into the plug, and a parachute flare 2 is contained in the casing by a removable closure 18. In operation, a sufficient voltsage is applied across the contact 6, 23 to fire the igniter 13 which burns the delay fuze 12 and so the charge 10, which initiates the fuze (not shown) of the flare 2 and also ejects the flare by removing the closure 18. An openended discharger, as in Specification 863,476, is used.

A process for the wet treatment of loose fibrous material comprises floating the material in a circulated treatment liquid and forming the loose fibrous material into a fleece on the outside of a perforated drum partly immersed in the liquid, by applying suction to the inside of the drum, the loose fibrous material floating freely in the liquid and being carried along by it. Apparatus for carrying out the process comprises a container I with eccentrically mounted perforated rollers 4 assisting the movement of the loose fibrous material through a bath of treating liquid 2 towards a partially immersed, centrically mounted perforated drum 6 to which suction is applied, and a squeezing device 5 removing excess liquid from the fleece formed on the drum 6. The treating liquid drawn into the drum 6 is wholly or partially recirculated to the bath. An alternative embodiment comprises two centrically mounted suction drums partially immersed in treating liquid. Several baths may be arranged successively, partition walls being provided directly below the pairs of squeezing rollers. In one embodiment, a perforated intermediate bottom is provided for the recirculation of liquid.

Title: Improvements relating to colour television receivers
Inventor: GARGINI ERIC JOHN
IPC: H04N9/22
Filed: 1956-12-19
Abstract: 880,517. Colour television. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 6, 1957 [Dec. 19, 1956; Feb. 27, 1957], No. 38627/56 and 6575/57. Addition to 871,367. Drawings to Specification. Class 40(3). A colour television receiver according to Claim 2 of the parent Specification is characterised in that the means for producing the indexing signal comprises means for causing the cathod-ray tube screen to emit secondary electrons in response to excitation by the beam more readily when the beam is directed at selected cycles (i.e. groups of three, red, green and blue) of the phosphor strips for substantially the entire cycle than when directed at other cycles of the phospor strips, the indexing signal being derived in response to secondary electron emission caused by the electron beam of said tube. A first embodiment of the invention, Figs. 1-3 (not shown), is in substance identical with that shown in Figs. 1-3 of the parent Specification. The indexing signal strips are deposited completely over every alternate group of three phosphors (as illustrated in Fig. 2 of the parent Specification) or over every third group of three phosphors. A second embodiment, Fig. 4 (not shown), differs only in that a pilot oscillation of 30 Mc/s is applied to modulate the tube beam and the indexing signal circuit is arranged to respond to a side band resulting from the modulation of the pilot oscillation by the indexing strips.

Title: Improvements in or relating to Devices for Producing Stereophonic Signals.
IPC: H04H1/00
Filed: 1966-08-31
Abstract: 1,152,733. Testing radio receivers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 31 Aug., 1966 [3 Sept., 1965], No. 38879/66. Heading H4L. A signal generator for testing stereophonic radio receivers includes a semi-conductor switch operated by a 38 KHz signal for generating the composite time-division multiplexed test signal and means are provided to compensate for the finite resistance of the switch. In the basic circuit, Fig. 1, an audio-frequency input is supplied to the base of a transistor 1 and appears in opposite phase at point 2. The signal at point 2 is supplied via a resistor 3 to the semi-conductor switch 4 controlled by the 38 KHz oscillations to periodically shortcircuit the output and the output at 5 is supplied to the stereo demodulator of the receiver under test. As shown, only the left-hand signal is to appear at output 5 but due to the resistance of the switch a residual voltage is present when the switch is closed which would appear as cross-talk in the right-hand channel. In accordance with the invention a voltage is derived from the emitter resistor 8 to balance out this residual voltage. If the tapping on resistor 8 is adjusted upwardly both the left and right-hand signals appear in phase opposition at the output 5. In a modification, Fig. 3, the two channels may be tested separately, a left-hand signal L and a right-hand signal R being supplied to the bases of transistors 11,12 respectively. When the switch 17 is open the left-hand signal appears at output 18 and the small residual part of the right-hand signal at output 18 due to the " open " resistance of the switch 17 and parallel resistor 24 is balanced out by a voltage derived from point 23 via resistor 22. When the switch 17 is closed substantially all the left-hand signal is dropped across resistor 19 since the resistance due to resistor 20 and switch 17 is relatively low, the small residual voltage being compensated by a part of the left-hand signal being supplied via resistor 22 and transistor 12. The resistor 24 is adjusted so that the compensation is correct for both the open and closed positions of the switch. In a detailed circuit, Fig. 4 (not shown), the switch consists of a pair of transistors.
