Filed: 1933-03-23
Abstract: 421,534. Colour photography. GASPAR, B., 38, Innsbruckerstrasse, Schoneberg, Berlin. March 23, 1933, No. 8847. Convention date, March 24, 1932. [Class 98 (ii)] A multipack recording material for colour films consists of silver halide layers, one or more layers being colourless and one or more layers coloured with a dyestuff which acts both as filter dyestuff for a colourless layer and for the formation of a coloured image in the dyestuffcontaining layer. The colourless layer or layers may contain colourless dye-forming substances which are converted into dyestuffs by subsequent treatment. A bipack comprises front and rear films sensitive respectively to blue and red, the front film being uncoloured and the rear film coloured red or yellow. For a tripack, a film sensitized on both sides is combined with a single film. The front side of the double film is sensitized to blue and is uncoloured, and the rear side is sensitive to green or red and contains a yellow dyestuff; the single film is sensitive to red or green and contains a red or a yellow dyestuff. The bluesensitive layer of both bipack and tripack may contain a colourless dye-forming substance, e.g. a leuco ester. After exposure and development, the coloured layers may be converted to dyestuff images as in Specifications 395,718, 397,159, and 397,188. The layers containing colourless dye-forming substances may be treated as in Specification 379,679, 416,566, or 416,660; alternatively, the colourless layer may be dyed after development. Specifications 397,170 and 408,991 also are referred to.

Title: An electrode holder for use in electric cutting and welding
IPC: B23K9/28
Filed: 1919-04-08
Abstract: 143,685. Marks, E. C. R., (Electric Arc Cutting & Welding Co.). April 8, 1919. Pliers.-In an apparatus for electric arc welding, repairing, or cutting of the type in which the arc is struck between the work and a metal electrode, the electrode is held between jaws at one end of two pivoted members, the other ends of which are automatically forced apart and adapted to receive electrical conductors. Two members 1, 2 of the metal such as manganese bronze, which are pivoted together at 5, have jaws 6, 7 to hold the electrode 19, the jaw 7 or both jaws being serrated to provide a good gripping surface. The other ends are forced apart by a V-spring 10 mounted on channels therein and the sockets 17, 18 carry the ends of a split conductor, the sockets being staggered as shown in Fig. 4 to eliminate breaking of the strands. The pivot is formed so that there is a clearance 22 between the ears 3 on the member 1 and the member 2, and a clearance 21 between the lug 4 on the member 2 and the member 1, and the pivot pin is secured in the ears and passes loosely through a straight or double tapered hole 23 in the lug as shown in Fig. 6, so that a slight transverse rocking motion between the members may be effected to grip electrodes of uneven shape to compensate the wear of the jaws, and also to give a maximum area of contact at whatever angle the electrode is placed in the jaws. The jaws have a tapering space between them so as to grip different sized electrodes with the same opening of the jaws. The members have longitudinal strengthening ribs in their outer sides and are provided with insulating strips 13, 14 secured by screws 15, which are covered by insulating material 16.

Title: Improvements in or relating to brake apparatus for railway and like vehicles
IPC: B60T13/46
Filed: 1927-03-31
Abstract: 290,415. McDermid, W. F., Spencer, A., and Glascodine, R. T. March 31, 1927. fluid-pressure.-Railway &c. brakes in which the vehicles are fitted with compressed-air brakes and the locomotive with vacuum brakes are provided with a valve device, comprising a valve 1 subject on part of its area to compressed air train-pipe pressure and the other part to vacuum train-pipe pressure, the other side of the valve being subject to spring and atmospheric pressure so that on a reduction in the pressure in the compressed-air trainpipe the valve is opened by the spring and atmospheric pressure to admit atmospheric air to the vacuum train-pipe. When the pressure in the vacuum train-pipe balances the loss in the compressed air train-pipe the valve is reclosed and graduated brake applications are thereby made. The pressures acting on the valve just balance when the valve is closed. The valve 1 is arranged in the vacuum train-pipe 2 just below the vacuum brake ejector and is cylindrical and a ground fit on a grooved spindle 15 having an axial bore 17 communicating by radial holes 18 with a connection 20 leading to the compressed air train-pipe so that the pressure in this pipe acts on the closed end of the valve 1. The seating of the valve 1 is provided in a cover 5 having a tubular extension 8, perforated to allow ingress of atmospheric air, and containing the spring 12 bearing on the valve 1. A screw plug 9 closes the outer end of the tubular extension and is provided with a pin 10 on which is mounted an abutment ring 11 for the spring 12. Hat, leather rings 2'1 and a spacing ring 23 ensure fluid tightness of the spindle 15. The spindle 15 is screw threaded at 24 in the valve casing so that it may be screwed inwardly by means of a handle on its squared end 25, to hold the valve 1 closed and out of action. A flange 26 limits its outward movement. The connection 20 may communicate with the pipe leading from the drivers' valve to the equalizing- reservoir to bring the valve device more quickly into action also for this purpose the valve 1 is provided with an internal vein 1<a>, which brings into action the pop-valve principle.

Title: Stepped grate
IPC: F23H7/06
Filed: 1927-03-31
Abstract: 268,809. Lomshakoff, A. S. March 31, 1927. Addition to 257,960. [A Specification was laid open to inspection under Sect. 91 of the Acts dated April 11, 1929]. Grates.-In stepped grates having the grate bars arranged alternately in two groups which make oscillatory movements longitudinally of the grate, as described in the parent Specification, the frames of the grate bars are driven by bellcrank lever mechanism from a transmission shaft or an electromotor in such a manner that they make oscillations which are divided up into smaller successive partial oscillations. As shown diagrammatically in Fig. 3, a crank 3 of variable length drives through a connecting-rod 4 a bellcrank lever 5, 6, 7 connected by rods 8 with the grate frames. The axis 6 of the bell-crank lever is made to trace out the circle 10 continuously so that the frames make successive partial oscillations such as 9, 11 which together make up the whole oscillation 12. By varying the speed of rotation of the axis 6 the length and number of the partial oscillations can be varied. The driving shaft 1 drives through gearing 14 a spur-wheel 15 in which is eccentrically set a coned crank disc 18, Fig. 4, integral with the crank-pin 3, the hub 16 of the wheel 15 being mounted in a bearing of the box 17. A spindle 20 integral with the crank disc 18 passes through a cover 21 bolted to the hub 16 so that by a nut on the screwed end of the spindle 20 the cone of the disc 18 can be forced into the spur-wheel 15 to fix the crank disc to the spur-wheel. The throw of the crank 3 is equal to the eccentricity e of the crank disc in the spur-wheel so that by turning the crank disc relatively to the spur-wheel the throw can be varied between the limits 2e and zero. The shaft 1 also drives through a variable-speed shaft 30 and gear-wheels 32. 33 a shaft 31 having a worm 29 driving a worm-wheel 28 mounted on a fixed shaft 27 and integral with an eccentric 26 which forms the pivot 6 of the bell-crank levers 5, 6, 7. Fig. 8 shows the variable-speed gearing giving three speeds of the worm-shaft 31 and comprising the shaft 30 on which are mounted the gear-wheel 32 and two toothed clutches 34, 35, the clutch 35 being double and the clutches being adapted to engage any one of three driven gear wheels loosely mounted on the shaft. To prevent two clutches being put into action at once the hand lever 36 of the clutch 34 has pivoted to it a bolt 38 having an eye 39 through which the hand lever 37 of the clutch 35 passes. When the clutch 34 is in action, as shown, the bolt 38 engages an aperture 40 in the lever 37 to keep the clutch 35 in the neutral position. The connecting-rod 8 pivoted to the bell-crank lever at 7 is connected by a pin 22 with the frame 23 of the grate and is guided by a piston 24 in a cylinder 25. The phase difference between the groups of grate bars may be adjusted. To facilitate the adjustment of the throw of the crank a scale may be engraved on the cover 21 and the spindle 20 provided with a pointer. Specification 258,294 is referred to.

Title: Improvements in or relating to circuit arrangements for repeating or amplifying electrical signals
IPC: H04N5/14
Filed: 1946-03-25
Abstract: 610,107. Valve amplifying circuits. NIND, E. A., and WHITE, E. L. C. March 25, 1946, No. 9082. [Class 40 (vi)] . A cathode follower amplifier circuit has separate cathode circuit and anode circuit supplies 17, 18 which are energized from a common source, variations arising from the common supply source are prevented from appearing in the amplified output in a substantial degree by relating the effective electromotive forces of the separate supplies to their internal resistance 19, 20 to the effective cathode load resistance 16 and to the differential anode resistance of the valve. The cathode and anode supplies preferably have a constant internal resistance in value proportional to their effective electro-motive forces and the ratio of their effective electro-motive forces is made equal to the ratio of the cathode load resistance to the differential anode resistance of the valve; so that variations in the common supply source do not appear at the output terminal 15. The supplies are preferably so constructed that the transit time through each of a disturbance originating in their common source is the same. In a modification, Fig. 2 (not shown), the sources are connected to ground through a further source which only carries the output current to enable the output steady potential to be set at. any desired value independently of the cathode supply. The further source since it can be of low current and voltage rating is easily highly stabilised.
