Filed: 1968-02-15
Abstract: 1,190,511. Coumarinyl-v-triazole oxides. J. R. GEIGY A.G. 15 Feb., 1968 [16 Feb., 1967], No. 7483/68. Heading C2C. [Also in Divisions C3 and C4] Novel coumarinyl-v-triazole oxides of the general Formula (I) wherein V and W independently represent hydrogen or an optionally non-chromogenically substituted (i.e. substituted only by groups that do not themselves impart colour to the compound) alkyl, aryl, alkyl sulphonyl, alkenyl, aralkyl, cycloalkyl group, or a carbocyclic or heterocyclic aryl group consisting of at most 3 rings having 5-6 members, or a saturated heterocycle, or the sulphonic acid group or derivatives thereof, a secondary or tertiary acylamide group optionally non-chromogenically substituted, containing an aliphatic, carbocyclic or heterocyclic acyl radical, an alkoxy carbonyl or carbamoyl radical, a secondary or tertiary di- or tri-azirylamino group non- chromogenically substituted as defined, or V and W together represent a tetramethylene group optionally substituted by alkyl groups (C 1 -C 4 ), or a C 5 -C 5 -cycloalkyl ring condensed with a benzene ring optionally substituted by alkyl groups (C 1 -C 4 ), the benzene ring of which may also be nonchromogenically substituted, Y represents an optionally substituted mononuclear carboxyclic or heterocyclic aryl group conjugated with the coumarin ion, R 1  and R 4  independently represent hydrogen or alkyl (C 1 -C 4 ) and R 2  and R 3  independently represent hydrogen, alkyl (C 1 -C 4 ), alkoxy (C 1 -C 4 ) are prepared by oxidizing oxime hydrozanes of the general Formulµ (IIa, IIb) Generally this oxidative ring closure is effected by using copper sulphate in pyridine/water. These oxime hydrazones are themselves prepared by reacting, in any order, α-diketones, hydroxylamine and 7-hydrazino-3-arylcoumarin of the general Formula IV wherein R 1 , R 2 , R 3 , R 4  and Y have the same meanings as above. In the examples several oxime hydrazones are prepared. Other intermediates isolated are methylphenyl glyoxal-[3-phenyl-coumarinyl-(7)]-hydrazone prepared from benzylmethyl ketone and the diazonium salt derived from 3-phenyl-7- amino coumarin and 1-(p-chlorophenyl)-oximinopropane-2-one prepared from the diazonium salt produced from p-chloroaniline and the reaction product of nitrous acid and saponified acetoacetic ester. The latter product is then reacted with 3-phenyl-7-hydrazino coumarin to form 1-(p-chlorophenyl)-1-oximino-propane-2- one-[3-phenyl-coumarinyl-(7)]-hydrazone. 1-[3- Phenylcoumarinyl-(7)-hydrazono]-propan-2-one is prepared from diazotized 3-phenyl-7-aminocoumarin and saponified acetoacetic ester.

Title: Improvements relating to photographic apparatus
IPC: G03B17/52
Filed: 1962-02-27
Abstract: 940,103. Processing photographic sheets. INTERNATIONAL POLAROID CORPORATION. Feb. 27,1962 [March 6, 1961] No.7615/62. Heading G2A. In photographic apparatus having pressureapplying members for guiding two sheets into juxtaposition and pressing them together, a tube of photographic processing composition is movable lengthwise against a cutter so that the tube is slit open lengthwise, and the composition is ejected through the slit and fed between the sheets by means of a nozzle. As shown, the apparatus is embodied in a camera (Fig. 1), the two sheets being a photosensitive sheet 16, on which a latent image is formed by exposure, and a second sheet 18 on which the final positive print is made. The two sheets, superimposed, are unwound from reel 14 and then separated as they pass round roller 26. Sheet 16 is passed over a support plate 22 in the focal plane of the camera, where the exposure is made. The light enters the camera through a lens (not shown) and is reflected at right-angles by a mirror 36 on to the sensitive sheet on plate 22, thus affording a more compact camera structure. After exposure, the two sheets come together again between pressure rollers 32, 34, a device 40 feeding a supply of processing fluid between the sheets as they converge, so that a positive print is formed on sheet 18. The sheets are then pulled out through an opening 38 in the camera. One form of the feeding device 40 is shown in more detail in Figs. 3 and 5. The processing fluid, which may be quite viscous, is provided in a thin-walled flexible tube 42, closed at the rear end 44. This is drawn forward by drive rollers 60, 62, and as it moves along it is slit down its length by engagement against a fixed cutter blade 58. The fluid is distributed by a nozzle 50 which has a narrow divergent passage 52. Opening into the rear of this passage is a conduit 56, which curves round as shown to enter the slit into the tube 42, just fitting therein. As tube 42 is drawn along, the fluid it holds is thus forced through the conduit into the passage 52, the fixed nozzle 50 having lips 54 which extend closely into the nip between rollers 32, 34 (Fig. 5) so that the fluid is applied just as the two sheets come into contact. The slit and emptied tube 42 is pressed flat between rollers 60, 62 and passes to a take-up spool. A further form of the fluid-feeding device is shown in Fig. 7. As the fluid-containing tube 42 is drawn forward by roller 86, and slit by the cutter 82, the fluid comes against the end of a fixed rod 92, and is diverted directly into the passage 72 leading to the application nozzle. The rod 92 can, if required, be moved across the opening of the passage 72 to act as a cut-off valve. Specifications 684, 592, 714, 412 and 940, 104 are referred to.

Title: Improvements in or relating to electric signal pulse controlling circuits
IPC: H04N5/067
Filed: 1937-03-18
Abstract: 497,637. Television; wireless receiving apparatus ; thermionic distributers. PERCIVAL, W. S., and WHITE, E. L. C. March 18, 1937, No. 7941. [Classes 40 (iii) and 40 (v)] Controlling signals applied to one of two unidirectional conductors 1 with a common electrode 9 allow or prevent the passage of signals through the other. Normally, current through the diode 9, 4 makes the cathode 9 positive so that no current flows to the other anode 13 when signals are applied to terminals 6, 7. When signals are to be passed, a negative pulse is applied through terminals 2, 3 to the anode 4 and stops the current to it. Current is then able to flow to the anode 13 and the output is taken at terminals 11, 12. At the other times the terminals 2, 3 may be used as the output for the signal. According to modifications: the biassing potential of battery 5 is negative, and a pulse of greater positive magnitude applied to the terminals 2, 3 ; the resistance 8 is omitted, a resistance is inserted in the lead to the anode 13, the signal is applied to the terminals 11, 12, and the output taken from the terminals 6, 7, Fig. 2 (not shown). The circuit is used for obtaining an automatic gain controlling potential from the synchronizing signals in a television signal, Fig. 3 (not shown), in a thermionic distributer for multiple signalling as described in Specification 470,495, or for providing synchronizing signals in television. Specification 491,728 is referred to.

Title: Improvements in or relating to brakes for colliery wagons and other vehicles
IPC: B61H1/00
Filed: 1927-03-28
Abstract: 289,612. Naylor, G. J. W., and Sheppard, J. March 28, 1927. Actuated or applied .by backward pressure of tractor or relaxation of pull or push; locking by positive or frictional detects.-An axle of a colliery wagon or other vehicle is so mounted as to be capable of movement longitudinally in relation to the body of the vehicle whereby in the event of backward movement on an incline the wheel or a part rotatable therewith engages a positive detent or a brake block. As shown in Figs. 1 and 2, the axle 1 which is capable of limited horizontal sliding movement in the .elongated pedestal 2 assumes the position shown when the vehicle is being hauled in the direction of the arrow but if the vehicle runs back the axle moves to the right hand in the pedestal and brings projections 4 thereon into engagement with fixed detents 7. To ensure that the axle shall remain in the position shown when the vehicle is being pulled forwardly, and to prevent it from sliding therefrom when the vehicle is being lowered down an incline, the coupling hook 14 is attached to a lever 10 capable of slight pivotal movement on a pin 11 on the body 3, the lower end of this lever pressing the ends of a slidable U-shaped bar 8 against the axle as long as a pull is exerted on the hook 14. To render the device entirely inoperative, the lever 10 may be raised by the provision of a slot through which the pin 11 passes, so as to engage the lower end of the lever with the bar 8, the vehicle being then hauled by a hook 13 connected to the pin 11. Alternatively the device may be rendered inoperative by dropping a vertical U-shaped bar slidable in a slot 16 in front of the bar 8. According to Fig. 6, a longitudinally slidable member 20 carries two projections 21, one or the other of which can be brought into position for engagement with the projection 4 on the slidable axle according to the direction of the movement of the vehicle that it is desired to prevent. The member 20 can also be placed in an intermediate position in which neither projection is operative. The member 20 is actuated by a bell-crank 23 and a sliding rod 25 connected to a transverse lever 28 pivoted on the end of the body. The movement of the rod 25 in either direction from the central is opposed by springs 27. A further construction comprises a pair of pins arranged parallel to the axle on a common lever, actuation of which projects one or the other into the path of the projections 4. According to the Provisional Specification instead of the projections 4, 21, there may be provided a pair of brake blocks adapted to engage the wheel and interconnected so that one or the other may be placed in operative position according to the direction of movement of the vehicle that it is desired to prevent.

Title: Improvements in or relating to variable-speed motion-transmitting devices
IPC: H03J1/18
Filed: 1946-03-19
Abstract: 609,651. Variable-speed gearing. P.R.T. LABORATORIES, Ltd., and BYFORD, M. S. March 19, 1946, No. 8554. [Class 80 (ii)] [Also in Group XL (c)] In a variable-speed device suitable for the tuning control of radio apparatus giving a large and relatively small speed-reduction ratio, a shaft 10 has secured to it a disc 17 with a V-section groove 18 of involute spiral shape formed in its forward face, and a gear-wheel 14 loosely mounted upon it. A driven shaft 11 has fixed thereto a gear-wheel 13 meshing with the wheel 14 and a cord pulley 22, which serves for transmitting motion to the driven device, e.g. variable condenser. A ball 19, carried in the free end of a rocking arm member 20, engages the V-groove 18. The member 20 is loosely mounted upon the driven shaft 11, and is kept in frictional engagement with the pulley 22 by a spring washer 21. A pin 15 on the gear-wheel 14 is positioned so as to lie in the path of a pin 16 projecting radially from the shaft 10. On rotation of the shaft 10, the shaft 11 is rotated at a high reduction ratio by the movement of the ball 19 in the V-groove 18, until the pin 16 engages the pin 15, whereupon the drive is effected at a low reduction ratio through the gear-wheels 14, 13. In a modification, the driving and driven shafts are nearly coaxial and a direct drive is effected by a pin on the driven pulley engaging a radially-projecting pin on the driving shaft.
