Title: Improvements in or relating to magnetic shunts for use in watthour meters or other electro-magnetic measuring instruments of the induction type
IPC: G01R11/36
Filed: 1939-04-14
Abstract: 527,539. Supply meters. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. April 14, 1939, No. 11354. Convention date, April 28, 1938. [Class 37] A magnetic shunt for an induction meter comprises a plurality of parallel magnetic elements which are magnetically insulated from each other and from the pole faces and are designed to saturate at different flux values, the element that saturates first being nearest to the axis of the armature. As shown, the magnetic shunt comprises two or more parallel elements 12, 15, the element 12 which is nearest the axis of the disc 6 being designed to saturate first. The shunt element portions may be arranged to saturate progressively in a gradually enlarging section as the magnetic flux increases, this being achieved by extensions 10 of the poles 11 by-passing the shunt to a limited extent. A spacer 13 of non-magnetic material separates the shunt elements from the poles. To fix the shunt elements 12, 15 to the spacer 13 rivets 18 may be used or the elements may be in one piece with tie 16 as shown in Fig. 5. In the latter case the elements may be fixed to the spacer by tabs 20 and, if required, a rivet 19. Notches 21 may be provided in the spacer 13 to receive the tabs 20.

Filed: 1922-04-22
Abstract: 185,709. Etchells, Congdon, & Muir, Ltd., and Muir, F. April 22, 1922. Controlling reversing-gearing.-A lift is reversed without changing the direction of rotation of the engine by the following mechanism, which comprises means for braking the driven shaft during change of direction. An extension shaft C coupled to the engine shaft a carries a gear D and a sprocket-wheel D<1>. The gear D meshes with a gear d connected to the free member f<1> of a friction clutch F and a chain d<2> connects the sprocket D' and a sprocket d' formed integrally with the free member g' of a friction clutch G. The members f, g of the clutches are keyed to a slidable shaft E which is connected to a driven worm shaft b<1> by a sliding coupling K preferably forming part of a brake drum M. The shaft E is moved longitudinally by a lever N attached to a sliding rod n which is connected by a rod n<1> to a crank p on the shaft of the handrope controlling pulley P. A spring n<2> maintains the lever N in central position. The brakeshoes, which are applied automatically to the drum M, are released by a lever R, which is also connected to the crank p.

Title: The preparation of polymers containing vinyl chloride
IPC: C08F14/06
Filed: 1966-03-16
Abstract: In a process for making vinyl chloride polymers the polymerization reaction is stopped at a desired degree of conversion by adding at least one of the following compounds, ascorbic acid, dihydroxy-maleic acid, their anhydrides, and the oxidation products of carbohydrates, e.g. glucose, saccharose, or fructose when oxidized with H2O2 and ferrous salts. The process is preferably effected at low-temperature and in the presence of a catalyst comprising a tetravalent cerium salt and an organometallic compound of germanium, tin or lead, and the reaction mixture is generally at a pH below 4 when the stopping compound is added.  The polymers are highly crystalline with a syndiotactic configuration.

[Also in Division B3] In a shear equipment comprising two shears separately driven by two motors a shiftable clutch in the transmission is arranged so that one shear can be disengaged from its drive means and at the same time both motors geared together for driving the other shear. Two rotary shears 7 and 8 are mounted on baseplates 5 and 6, the upper blade-carrying arms 9, 10 are mounted on shafts 11 and 12 and the lower blade-carrying arms are mounted on shafts 15 and 16. The upper and lower shafts of each shear are connected by gearing. The motor 4 drives the shaft 12 through reduction gearing 36, 37 and 39, and the motor 3 drives the shaft 11 through reduction gearing 28, 30 and 32. The first pinion 28 of the drive to shaft 11 is free on the shaft 19 and is coupled to it by a dog clutch 26 splined to the shaft. A fixed shaft 46 is mounted between the two upper shafts and carries the freely rotatable gears 30 and 31 which form part of the reduction gear trains of each shear. The gear 31 also meshes with pinion 46 which rotates freely on the shaft 19 and is coupled to it by the dog clutch 26 when the clutch is moved to its alternative position. Operation.-With the clutch in the position shown in Fig. 1 the motor 3 drives the shear 7 and the motor 4 drives the shear 8. With the clutch 26 in the alternative position the shear 7 is at rest and the shear 8 is driven directly by the motor 4 and also by the motor 3.

Title: Improvements in and relating to aeronautical photography
IPC: G03B15/00
Filed: 1926-05-05
Abstract: 251,999. Hyden, C. May 8, 1925, [Convention date]. Aeronautical surveying apparatus. - A camera is so mounted on an aircraft that it may be oscillated about a substantially horizontal axis parallel to the direction of flight, and means are provided for operating the shutter to make exposures when the camera assumes predetermined inclinations to the vertical, for holding the camera stationary relative to the aircraft during an exposure, and for winding the film and resetting the shutter on the completion of an exposure. The inclinations are so chosen that a succession of overlapping pictures of the ground is obtained, which may be assembled to form a complete picture of the area photographed. In the form shown, the camera is carried by a frame 2, Fig. 1, mounted on an horizontal axis in a base 1 held above the floor of the fuselage as by straps 43 secured with the interposition of shockabsorbing buffers 44, or a gyroscopically stabilized frame, to beams of the aircraft. Fast with the frame 2 is a slotted arm 9, Fig. 2, engaging an adjustable pin 11 on an arm 13 which is pivoted at 14 to the base 1, and is provided with a closed cam-groove 15 engaging a pin 16 on a wheel 17 pivoted at 18 to the base 1. A motor 22, driving the wheel 17 through gearing 21, 20, produces the desired oscillation of the frame 2, and its circuit includes a rheostat for regulating the speed of oscillation of the frame. The camgroove 15 is so shaped that the camera is allowed to remain momentarily stationary at certain inclinations, and it is positively held in these positions by a spring locking-device in the hub 6 on the axis of the frame 2. At each arrest of the camera, a stud 27 on the wheel 17 bridges electrical contacts 26, thereby closing a circuit including an electromagnet which actuates a trip to release the camera shutter. The movement of the trip also closes contacts to complete the circuit of a motor which winds the film and resets the shutter. The electrical equipment includes a manually-operable switch in order that the trip controlling the shutter may be actuated to make an exposure at any desired inclination of the camera, independently of the exposures which are made automatically when the contacts 26 are closed.

Abstract: 917,797. Magnetic storage devices. AMP Inc. April 4, 1961 [April 13, 1960], No. 11998/61. Class 38 (2). [Also in Group XXXIX] A transfluxor type device for storing any one of a series of discrete signal levels comprises a core 12 of rectangular hysteresis loop material, transformer action between A.C. energized read winding 24 and output winding 26 linking aperture 16 being permitted when a signal applied to set winding 22 reverses all or an appropriate part of the flux in the material between apertures 16 and 14, reversal of the flux around the outer half of the core by the short signal pulses being prevented by the low resistance closed winding 28. The A.C. output then depends on the amount of flux switched which depends on the signal level stored. The clearing pulse applied to winding 20 when the core is to be cleared is relatively long so that winding 28 does not prevent switching of the flux in the core portion it links during clearing. The core may be of ferrite or steel ribbon.
