Title: Improvements in or relating to devices for fixing forme saddles on forme cylinders of rotary presses
IPC: B41F27/10
Filed: 1968-05-29
Abstract: 1,204,572. Printing surfaces. SCHNELLPRESSENFABRIK FRANKENTHAL ALBERT & CIE A.G. 29 May, 1968 [19 June, 1967], No. 25619/68. Heading B6C. Forme-bearing saddle 2 fits over two locating pins 3, projecting one behind the other from the surface of printing cylinder 1, and is held by engagement of eccentric-operated hooks 6 with co-operating abutments 5. Each hook 6 has a circular bore 24, which surrounds an eccentrically mounted spindle 7 with some free play, and is rotatable about the spindle 7, within limits imposed by a stop 25 on hook 6 and a projection 26 from the spindle 7 beside the hook 6. During attachment of a saddle the hook 7 first moves over abutment 5, turning with the spindle 7, then is drawn radially inwards by continued movement of the spindle 7. If the hook 7 does not engage abutment 5 correctly, but instead contacts its edge, premature engagement of stop 25 and projection 26 stops the operation before the spindle 7 has turned through its full normal travel. Within each hook 6 a spring 19 presses a movable plate 23 against the spindle 7. Two spindles 7, controlling hooks 6 engaging a single saddle, may be coupled by spur gears and rotated by a hand lever 14, click-stopped at the limits 16, 16<SP>1</SP> of its travel.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T17/18
Filed: 1924-10-28
Abstract: 230,414. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Thomas, T. H.). March 10, 1924, [Convention date]. Fluid - pressure.- The control of the feed valve used for charging the train pipe is effected by the pressure conditions at a point remote from the point in the train pipe at which fluid is supplied thereto through the feed valve, whereby the regulating-diaphragm of the latter is subject more nearly to the actual train pipe pressure, so that the charging ports of the feed valve may be made larger than usual. In the form shown, the diaphragm 13 of the feed valve is subject through a pipe and passage 17 to the pressure in the train pipe 3 at the driver's valve, when the latter is in charging position, through a cavity 21 in the rotary valve 6. If this pressure is less than that corresponding to the setting of a spring 14, the diaphragm is depressed to open a valve 15, whereby a chamber 9 above a piston 10 is vented to the pipes 17, 3. The piston is therefore raised by main reservoir pressure supplied by a pipe 22 to a chamber 11, and the supply pipe and passage 18 is fed through ports 19 in a slide valve 12. Pressure fluid is thus supplied to the chamber 5 of the driver's valve, and thence through a port 20 to the train pipe 3 until the pressure in the chamber 16 raises the diaphragm to allow the valve 15 to close. The pressures on the two sides of the piston 9 then equalize through a passage 23 and a restricted port 24, so that the piston and slide valve are moved to their lower position by a spring 25, and the supply to the train pipe is cut off. The control and supply pipes 17, 18 are permanently connected through a restricted port 26, so that in the event of leakage from the pipe 18 and chamber 5 when the driver's valve is not in charging position, the fall of pressure is communicated through the pipe 17 to the chamber 16, whereby the valve 15 is opened to restore the pressure in the pipe 18 and chamber 5. The possibility of the valve 6 being lifted off its seat by the pressure in the train pipe in the event of leakage from the chamber 5 is thus obviated. The stem 27 of the piston 10 may be provided with a cylindrical portion 28 at its lower end which is guided in a bushing 29.

Filed: 1929-08-23
Abstract: 317,833. British Thomson-Houston Co., Ltd., (Assignees of Severin, C.). Aug. 23, 1928, [Convention date]. Multiple-filament lamps; making lamps.-Two filaments 20, 21 of high candle-power are arranged at equal distances from the base of the bulb and a third filament 22 of low candle-power is placed nearer to the base and approximately in the plane of one of the main filaments, with which it may be connected electrically in series. The main filaments may be in parallel planes, as shown. Also, in a bulb having at least three filaments, they are supported by two pairs of leading-in conductors 12 sealed into the stem and arranged parallel and equally spaced from each other in the pinch. The parts may be assembled in a stem-making machine of the kind described in Specification 223,204, the pinching-jaws 13, 14, Fig. 4, being shaped to form a cruciform pinch about the four wires 12, as shown in Fig. 2. The position of the exhaust aperture through the pinch, in a stem of the kind described in Specification 147,293, is determined by a lug 16 on the jaw 14. Since the filaments 20, 21 lie on opposite sides of the axis of the bulb, the bulb socket 42 of the lamp reflector 41, Fig. 12, is made eccentric with respect to the axis thereof to enable the filament 21 to lie at the focus and in the axis of the reflector. Three unequallyspaced cap pins are provided on the base to ensure the correct positioning of the filaments. Specification 303,114 also is referred to.

Abstract: 389,828. Controlling motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and POOL, W. J., Chelmsley, Barby Lane, Hillmorton, near Rugby. Sept. 22, 1931, Nos. 26483 and 26579. [Class 35.] A Schrage motor 1 is controlled to run at a speed proportional to that of a master motor 3 by means of a differential device 7 acting upon brush-shifting gear of the motor 1, and upon disconnection of the motors from the supply the motor 3 is brought to rest before the motor 1 so as to ensure that the differential device returns the brush-gear to its low-speed position in readiness for restarting. Upon closure of contactors 13, 15 the motors are energized and a spring-applied brake 10 is released front the motor 3. If the motor 1 fails to start, the differential device 7 moves the brush-gear towards the high-speed position, but movement is arrested by engagement of a projection 24 on the brush-ring with a pawl 25. Subsequently a time-delay relay, or a speed-responsive contact on the motor, causes electromagnetic withdrawal of the pawl from the path of the projection. Upon opening of the contactors 13, 15 the brake 10 is applied to the motor 3. In a modification, instead of limiting the movement of the brush-gear by a pawl 25, the starting of the motor 3 is delayed by a timedelay relay.
