Title: Improvement in Automatic Shutter Trippers for Cameras.
Inventor: WEBSTER EDGAR EMER
IPC: G03B9/58
Filed: 1916-03-17
Abstract: 101,311. Webster, E. E. March 17, 1916. Shutters.-A device for actuating a shutter automatically after a predetermined time-interval comprises a cylinder 5 containing a piston 7 actuated by a spring 12 under the control of air escaping from an adjustable port in the cylinder. The device is primarily for use in connexion with a flexible cable release 1 and has fingers 15 which engage the stationary flange 17. In the form shown in Fig. 2. the piston 7 is carried by a barrel 8 having slots to accommodate screws 10, which project from the cylinder 5 and carry a cross-piece 10<a> which forms an abutment for the spring 12 and carries a screw 10<b>. As shown, the device is set, and when released, the spring 12 forces the cross-piece 10<a> &c. upwards until the screw 10<b> engages the head 3 of the cable and releases the shutter. In the modification shown in Fig. 5, the piston 7 is secured to a rod 19 on which is loosely carried a rectangular frame 21. When a catch 13 is released, the cylinder 5 is forced upwards and engages and lifts the frame 21 to bring it into contact with the head 3 and release the shutter. The air port is regulated by a screw 6.

Title: Improvements relating to apparatus for controlling the drive of a conveyor belt or other driven belt
IPC: B65G43/04
Filed: 1955-02-10
Abstract: 805,121. Endless belt conveyers. NILOS G.m.b.H., FORDERBAND - AUSRUSTUNG. Feb. 10, 1955 [Feb. 10, 1954; July 30, 1954], No. 4070/55. Class 78 (1). The drive to a conveyer belt is cut off if its speed falls below a predetermined level owing to slip between the belt and its drive by apparatus, including a speed-responsive roller driven by the belt which operates hydraulic means to supply fluid in accordance with the speed of the roller to a ram cylinder at least partly accommodated in the roller, the fluid acting on a spring-loaded piston within the cylinder which acts on means for cutting off the drive when the speed of the roller drops below a predetermined level. As shown, the speed-responsive roller 1 is one of the outer rollers of a set of troughing rollers 1, 33, 34 supported in a carrier frame 32 which is constructed such that these rollers lie higher than those of adjacent sets of troughing rollers to ensure continuous engagement of roller 1 with the belt. A cam 2 secured to the inside of the roller operates a pump 3 having inlet and outlet valves 4, 5 and supplying fluid from the interior of the roller to a ram cylinder 6 connected externally with the frame 32 and a control box 22. Piston 7 has a bore through it whose exit is adjusted in size by a needle valve 10 threaded in the piston rod allowing some of the fluid to return under the pressure of a spring 8 acting on the piston. Normally the spring is compressed until another bore 9 in the cylinder wall is uncovered, allowing the fluid to escape also through this bore. At this position a switch 13, linked by a push-rod 12 and bell-crank 11 to the piston-rod, is in the ON position. When the belt slows owing to slip between it and its driving drum, the bore 9 is first covered and then the piston slides inwardly, a pointer 15 on rod 12 indicating the rate of slip on a scale 16 while a rack 19 connected by lever 17 to rod 12 actuates a counter 20 whereby successive slippages are counted. When the belt speed falls to a value determined by valve 10, switch 13 is switched off, de-energizing the conveyer driving motor. The motor is restarted through a relay 14 which is adapted to maintain its contacts closed until the normal time for the conveyer belt to run up to speed, whereupon in the absence of further slip the contacts 13 will have re-closed.

Title: Carburettor, particularly for aircraft engines
IPC: F02M7/18
Filed: 1925-02-16
Abstract: 230,043. Bayerische Motoren Werke Akt.-Ges. Feb. 25,1924, [Convention date]. Spray carburettors -To enable super. dimensioned aero-engines to be run for short periods on the ground with throttle fully open, as e.g. at starting, or in emer. gencies, the passage leading from the floal chamber a to the nozzle c<1> is fitted with a rotatable plug d having bores e, f, of different diameters. The bore f is comparatively small and serves to supply fuel during normal running at all altitudes. The larger bore e is brought into use for the special running conditions referred to above i.e. with the greatest possible output on or near the ground. The cock is retained in its seating by a spring and is rotated to vary the bores in action either by the hand direct, or from a distance through a Bowden wire attached to the handle g. The invention is particularly applicable to multi-chamber carburettors as described in Specification 145,648. Reference has been directed by the Comptroller to Specifications 177,197 and 196,197.

Abstract: 634,556. Labelling-machines. HESSON, C. M. Feb. 19, 1948, No. 4962. Convention date, July 1, 1939. [Class 73]  In a labelling-machine of the kind in which cans or other containers are rolled through the machine to pick up a label, means are provided for positioning a can having lugs or handles so that the lugs will pass through corresponding holes in the label as the can rolls by. The cans are rolled along spaced apart tracks 16, 17 by means of belts 22. Situated on each track is a positioning member 45, 46 each of which comprises a frame 51 having two wheels 52, 55 projecting through the tracks. As the can rolls along, a ramp member 63 on each positioning member 45, 46 raises the can above the track and allows it to be supported by the wheels 52, 55. The wheel 62 is freely rotatable whilst the wheel 55 is toothed and rotatable only in a clockwise direction, Fig. 4, so that in this position the can is rotated without rolling. The positioning member 45 is provided with a spring-pressed stop 76 which engages a lug or handle 44 on the can, as the can rotates. On engagement of the lug with the stop, continued movement of the belts 22 tilts the can into the position shown at D, Fig. 4, from which position the can rolls down an inclined ramp 69 on to the tracks 16, 17 correctly positioned, after which the can passes over the label pile, the lugs 44 passing through holes provided in the label. The positioning members are adjustable along the tracks. Means are provided for pasting the cans and for applying a transverse strip of adhesive to each label. U.S.A.

Abstract: 758,212. Igniters for rocket motors. ENGLISH ELECTRIC CO., Ltd. Feb. 18, 1955 [Feb. 19, 1954], No. 5036/54. Class 9(2) An igniter 1 for a rocket motor 3 comprises a case 2 containing the ignition mechanism and having an end closure 4 on which is mounted the arming mechan- .ism 5. Within the other end of the case is a cap 6 held in place by a circlip 7 and a spring 8 which urges a piston to the armed position. The hollow stem 14 of the piston houses a tube 10 containing the ignition substance, the tube acting as a core along which the piston can slide. An annular channel for the flow of gas from one side of the piston to the other is provided by a recess 11 in the wall of the case 2. Vents 12 are provided in the closure 4. Lead wires for electric current passing through sealing screws 13 are used to ignite the substance in the tube 10 and the hot gases liberated pass through vents 16 in the stem 14 into the case 2. Before the igniter is armed, the piston is depressed by a pin 21 so that a plug 15 which terminates the stem 14 is pressed into an aperture in the cap 6, the plug 15 and the cap together forming a valve. In this position of the plug, the gases entering the case 2 pass through the recess 11 to discharge through the vents 12. Sealing rings 17, 18, 19, 20 prevent undesired leakage of gas. The arming mechanism 5 comprises a locking member 24 which locks a pivoted arm 22 carrying an adustable screw 26 in engagement with the pin 21. To arm the igniter, the locking member 24 is withdrawn, whereupon the arm 22 swings on its pivot and allows the pin 21 to move outwards releasing the piston, which is then moved bv its spring 8, so that the plug 15 is withdrawn from its seating. The hot gases from the tube 10 then pass to the rocket motor to ignite the fuel.
