Title: Improvements in or relating to circuit breakers
IPC: H01H71/52
Filed: 1965-03-30
Abstract: 1,082,126. Automatic circuit - breakers. MURRAY MANUFACTURING CORPORATION. March 30, 1965 [Aug. 7, 1964], No. 13439/65. Heading H2B. An overload-responsive circuit-breaker has a toggle assembly 57, 59, 67 connected to a pivoted handle 19 and extending towards a movable contact 31 pivoted at 32 and biased towards the open position by a spring 34<SP>1</SP>. The link 59 is slotted to receive the pivot c of the link 67 and is surrounded by a compression spring 69. When overload occurs, an electromagnet 23, 47 attracts its armature 51 to release a trip lever 55 which is turned anticlockwise by a spring 34 to release the " knee " of the toggle assembly. The end of the link 67 slides off the contact 31 which moves to its open position and a spring 56 is able to restore the handle 19 to its " off " position to automatically reset the lever 55. In the off position there is no spring force in the toggle assembly which is over-set to the left by a projection 61 on the link 59 engaging a fixed abutment 63. When the handle is moved to the " on " position shown, the link 67 is initially moved downwardly until a projection 71 on the link engages an abutment 73 on the casing. This prevents downward movement of the link 67 so that the spring 69 is compressed until the toggle 59, 67 is cammed over-centre into the position shown and the projection 71 is released from the abutment 73. When this occurs the link 67 is thrust rectilinearly downwards to close the contacts.

Title: Improvements in distributing apparatus for the control of two or more distinct and concomitant devices
IPC: F16K11/07
Filed: 1937-05-13
Abstract: 495,711. Controlling aircraft and endless track vehicles. MERCIER, J. May 13, 1937, No. 13525. [Class 4] [Also in Group XXXI] Means for maintaining in step fluid-pressure operated concomitant-devices such as aircraft flaps, surfaces and landing-wheel brakes and brakes on endless-track vehicles, includes a slide-valve laterally and longitudinally balanced and connected with the control members of, e.g. the aircraft, so that movement of the member consequent upon the effect on the aircraft of lack of symmetry in the motion of the devices effects movement of the valve to bring the devices again into step. In one form, movement of a balanced valve 22 connects orifices 24, 241 to supply or exhaust respectively. The orifices 24, 24<1> are connected, respectively, to orifices 3, 5 of a valve-housing 1 in which the slide-valve 2 moves. Passages through the valve and grooves in the housing effect balancing of the valve. The valve 2 is grooved so that orifices 4, 4<1> connected to the operating- elements for the devices, on movement of the valve, are connected to supply or exhaust through ports 7, 7<1>, 11, 11<1>. Non-return valves are provided at the orifices 3, 5. In a modification, the port 7 is omitted, the valve being provided with two additional grooves which are connected. In a further modification, a grooved valve co-operates with a grooved housing so that without moving the valve, fluid may be supplied or exhausted merely by regulating the supply or exhaust. In this form leakage of fluid past the ends of the valve is recovered. In a still further modification, the valve is completely balanced in its mid-position and always tends, when moved, to return to that position. The valve may be fixed and the casing movable.

Abstract: 127,819. Leumann, R. June 1, 1918, [Convention date]. Packeting by wrapping-up. - A machine for wrapping-up sweets &c. into packages with twisted ends comprises means for feeding a sweet and a tubular wrapper to a holding- device adapted to carry the package to the twisting-mechanism and to hold the package stationary while the ends are being twisted. In the machine shown in Figs. 1 and 2, the sweets 84 are placed in holes 4 in an intermittingly rotated table 5 and drop through a hole 6 in a table 7 into a shoot 8. A web 14 of paper is formed into a tube 15 by a folder 12 arranged coaxially with the end of the shoot. The sweet is arrested by a constriction formed in the tube by levers 17, 19 which engage the tube each time a sweet passes into the shoot. The sweet is moved up to the constriction by a swinging pusher 11. Fig. 2, which can pass through a slot 9 in the shoot. The tube and the sweet are then gripped by fingers 39 on the feeding-mechanism 32 and moved to a position slightly to the right of that shown in Fig. 1, whereupon scissors 26, 28 sever the tube. The feeding-mechanism then moves to the position shown in Fig. 1, the holding-device 32a advances, and fingers 50 thereon grip the package. The fingers 39 then open, and the holding-device is retracted to carry the ends of the wrapper into engagement with fingers 59 on the twisting-devices 54, the fingers being thereupon closed and the devices rotated simultaneously in opposite directions. Finally, the fingers 59 open, the holding-device is retracted a short distance, the fingers 50 open, and the package is stripped by pins 86 and falls through an aperture 85. The feeding-mechanism 32 comprises a sleeve 34 which is mounted in a guide 33 and reciprocated by a link 36, the fingers 39 being pivoted on the sleeve and connected by springs 40. The fingers are controlled by a sliding spindle 41 which is connected by links 43 to the fingers. The holding- device 32<a> is of similar construction to the feeding-mechanism and comprises the fingers 50, reciprocating sleeve 47, and spindle 51. The twisting-devices 54, Fig. 1, each consist of a sleeve 56, which can slide or rotate in a guide 55 and carries the pivoted fingers 59, which are drawn together by a spring and are controlled by a spindle 63.
