Filed: 1965-05-31
Abstract: 1,079,538. Cine projector. FRANCEECRANS SOC. ANON. May 31, 1965 [Oct. 9, 1964; April 1, 1965], No.23016/65. Heading G2E. In a cine projector, optionally of cabinet form with a built-in projection screen, two films of equal length are alternately projected, while continuously moving in synchronism with a rotating lens ring type of optical compensator, the previously projected film being simultaneously rewound. On completing the rewinding of film 8a on to supply spool 9a, notches in the film may operate micro-switches (not shown) or, alternatively, feeler arms (106b, b' Figs.11 and 22, (not shown) co-operate with the peripheries of film coils on the spools 8b and 9b to operate micro-switches (108, 108') Figs.20 and 21 (not shown). The micro-switches stop drive motor 29 and prepare it for reverse operation. On starting the projector, by means of start buttons 43 or by remote control or by means of a time switch, motor 29 is energized and drives the supply and take-up spools by means of belt (60) and film drive sprockets 26a, 26b directly through reduction gears Figs. 3, 7 and 8 (not shown). A further drive belt (54) Fig. 7 (not shown) drives sprocket 13. A centrifugal governor mechanism, driven from sprocket 13 ensures that microswitch (99) Fig. 14 (not shown), in the projection lamp circuit, is not closed until the film speed reaches the normal running level. Two projection lamps, in houses 19a and 19b, are cooled by a forced air draught. For film 8a, the preheating circuit of the lamp in housing 19a, is energized by switch (99) to light the lamp after a short delay and begin projection. An optical compensator in the form of a ring of projection lenses 7 Figs. 3-6 (not shown) is rotatably mounted on base-plate 1. The continuously moving films 8a and 8b drive sprockets 21a and 21b, respectively, whence the drive is transmitted through gearing or belts and pulleys to ring 7 Figs. 7-10, 18 and 19 (not shown). A further belt drive is provided from the film to an anti-flicker shutter (76) Figs. 3 and 4 (not shown) which is driven in the opposite direction to, and at ten times the speed of, ring 7. Mirrors (5a and 5b) Fig.3 (not shown) reflect the light from double width film gates 18a and 18b, upwardly, to mirror (4) and back-projection screen (3) Fig.1 (not shown). Sound heads 24a and 24b may be used. Film breakage during running is detected by arms (30a, 30b and 31b) (carrying sprockets 15a, 15b, 28a and 28b) which operate micro-switches (32a, 32b and 33b) Figs.7 and 8 (not shown) in the motor circuit. Sprockets 21a, b may be formed with the teeth of one now broader than those of the other Figs.15, 15a and 15b (not shown). The projector may be used to provide an image on the photo-cathode of a television camera image conversion tube (104a, b) Figs.23, 24a and 24b (not shown).

Abstract: 1,190,942. Oxychlorination of hydrocarbons in presence of a copper exchanged zeolite. MARATHON OIL CO. 18 May, 1967 [8 June, 1966], No. 23233/67. Heading C2C. [Also in Division Cl] Oxidative chlorination of hydrocarbons is effected by passing gaseous reactants comprising hydrocarbon, hydrogen chloride and oxygen at elevated temperature through a bed containing a catalyst consisting essentially of a zeolite conically bonded by ion-exchange to from 0À1-5% by weight of Cu and contacting the gaseous reactants with the catalyst for a time sufficient to enhance their reaction. Specified hydrocarbons are methane, ethane, propane, ethylene and propylene. In the oxychlorination of ethylene, at low temperatures, the principal product is 1 : 2 dichlorethane. At increased temperatures dehydrochlorination to vinyl chloride results. Thereafter vinyl chloride may compete with unchanged ethylene so that sequentially trichlorethane, dichlorethylene, tetrachlorethane, trichlorethylene, pentachlorethane, tetrachloethylene, are formed. Examples describe the oxychlorination of ethylene. Reference has been directed by the Comptroller to Specification 1,138,889.

Abstract: 925,398. Semi-conductor devices. SIEMENS & HALSKE A.G. July 7, 1959 [July 10, 1958], No. 23317/59. Class 37. A switching device comprises a semi-conductor body including four successive zones the inner pair of which are of opposite conductivity types and have lower resistivities than the adjacent outer zones. At least one of the outer zones has the same conductivity type as the adjacent inner zone but contains impurity of the opposite conductivity type sufficient to cause injection of minority carriers when the junction with the inner zone is forward biased but ineffective to render the junction non-conductive when reverse biased. The outer junctions 1, 3 of one PN+P+N diode (Fig. 3) according to the invention are formed by alloying and the central junction 2 by a diffusion technique. In another embodiment, of the PN+P+P type, the central junction is formed by diffusion and the P zone adjacent the P+ zone by alloying to the latter an indium tin alloy containing 2% by weight of arsenic. The resulting zone contains both donor and acceptor impurities, the former being essential if the device is to perform a switching function. Devices of the NN+P+P structure are also envisaged. When the externally applied voltage reverse biases the central junction all the devices exhibit high impedance below a critical voltage at which triggering to a low impedance state occurs. With the applied voltage reversed the PN+P+N device alone exhibits a high impedance, the others being conductive. The underlying theory of the switching mechanism is discussed. Specification 925,397 is referred to.

Patent GB-234765-A (GB)
Abstract: 234,765. Moore & Avery (Blackburn), Ltd., and Moore, J. E. Feb. 27, 1924. Healds and reeds, threading. - Relates to apparatus for selecting and separating warp threads of the type wherein a carriage A having a selector B with a hook at one side is caused to travel past the warp threads, which are suspended in tension between top and bottom clamping-members, the selector moving forwardly to engage a warp thread and then transferring it with a diagonal movement to a separator comprising two ratchet wheels D, along which the selected threads are spaced in position for enabling them to be drawn through the healds and reed by the operator. To prevent any thread that the selector fails to transfer to the seperator from springing past in front of the remaining threads and therefore out of its correct order for selection, the foremost warp threads are pressed inwardly by a plate G or like guide adjustably mounted in front of the warp threads on an arm g attached to the carriage. If the selector should take a thread towards the separator and then drop it, the thread does not spring past the unselected threads, but against the rear end of the plate G or returns to its original position. The selector transfers a thread on to the separator whilst this is making its forward or spacing movement, and commences its return stroke before such forward movement is completed, the selector B being mounted in a holder b<2> pivoted on a lever b<1> controlled by a cam b, whilst the separating-wheels D are operated by a spring-controlled pawl d<2> on a lever d<1> operated by an adjusbable eccentric d. The holder b<2> is spring-controlled and bears against an inclined guide b<4> whereby as the slotted arm b<1> oscillates a rocking-motion is also imparted to the selector B. An eccentric a operates lever-mechanism and a toothed rod for turning a ratchet wheel and gearing for traversing the carriage step by step, the engagement of the toothed rod with the ratchet wheel being controlled by a spring-controlled lever mechanism from a feeler C. The warp threads are deflected over the edge of the rail on which the carriage runs as described in Specification 7780/15. When threads accumulate on the separating wheels, a feeler F is turned and operates mechanism for breaking an electric circuit and thus stopping the machine.

Abstract: 1414016 Aerials; radio signalling STANDARD TELEPHONES & CABLES Ltd 17 May 1973 23528/73 Headings H4A and H4L A radiating cable arrangement, which may be installed along a roadway for broadcasting radio signals to drivers, comprises two closely spaced parallel cables A, B of the same kind, e.g. slotted co-axial type, and of equal overall lengths. The cable A, however, is sub-divided into two (or more) equal sections. R.F. signals are fed to the cables at one end of the arrangement, directly in the case of the cable A, and through means, such as length of fully screened cable K, in the case of the cable B, whereby a predetermined phase shift is introduced. Lengths of fully screened cable K<1> connect each adjacent pair of sections of the cable A, and provide a total phase shift which is equal to the aforesaid predetermined phase shift. The effect is, that at the beginning of each section of the cable A the signals in the two cables are brought more nearly into phase, so stepping up the magnitude of their resultant and compensating for attenuation over the previous section (Fig. 3, not shown). A typical value for the pre-determined phase shift provided by the cable K is 168 degrees (Fig. 2, not shown). Impedance matching between the cables and the signal source may be necessary.
