Title: Improvements in or relating to electric switches
IPC: H01H71/02
Filed: 1925-12-16
Abstract: 264,986. Brookhirst Switchgear, Ltd., and Hirst, J. A. Dec. 16, 1925. Controllers with automatic release devices; vices; controlling interlocking with auxiliary switches. - In motor controllers or switches provided with automatic release devices, the automatic devices are mounted on a hinged frame which, when the apparatus is in working condition, lies parallel to and in front of the main controller or switch gear; the frame can be swung back for inspection and is arranged to break the circuit connections in so doing. For an enclosed three-phase change-over motor starter having a switch drum B and stationary contacts E<1> - - E', a flat frame D attached to the casing by hinges d' inside the hinged cover a<1> carries overload devices o', 0<SP>2>, a no-volt device N, and plug or blade terminals e<1> - - e<5> arranged to make connection with the respective contacts E<1> - - E<5> when the apparatus is closed up from the position shown. The closing-up action also brings the tripping member of the no-volt device within range of the catch which holds the controller drum in the running position. The tripping member is so shaped that the catch is necessarily freed when the hinged frame is swung back. The cover carries a spring push T for tripping the catch manually when required. A mechanical interlock P prevents the reclosure of the drum controller while the frame with the automatic devices is in the swung-out position. Specifications 223,960 and 242,730 are referred to.

Title: Improvements in noise limiting circuit arrangements for radio receivers
IPC: H03G11/04
Filed: 1948-12-15
Abstract: 649,074. Radio interference suppression circuits. FITTON, Ltd., R. N., and BEAUMONT, F. H. Dec. 15, 1948, No. 32442. [Class 40 (v)] A noise limiting arrangement for radio receivers comprises a first diode and a load circuit, and a second diode, the cathodes being connected together and the second diode being negatively biassed by the output of the first, so that it conducts only during noise impulses to attenuate the demodulated output. In Fig. 1, carrier frequency is applied to tuned circuit 1 and detected by diode 4, 5 to provide a demodulated output from load circuit 2, 3. A second diode 7, 5 which is biassed by the output from load circuit 2, 3 smoothing being effected by a large condenser 10, is also fed with carrier frequency by means of a coil 8 which is coupled to tuned circuit 1. When the percentage modulation exceeds a predetermined value, depending on the degree of coupling of coil 8, diode 7, 5 becomes conducting, and the resultant heavy loading of tuned circuit 1 reduces the demodulated output from the first diode. In a modification, a further coil is introduced which is in series with coil 8 and is coupled to the primary of an input transformer, the secondary of which is constituted by the tuned circuit 1 coupled to coil 8. Fig. 3 shows an alternative arrangement in which the first diode 14, 15 is effectively in shunt with the tuned circuit, and the second diode 20, 15 is fed from a tapping on the tuned circuit 1.

An apparatus for supporting a heavy wheel and tyre assembly 18, for tread re-grooving, comprises a stand 11, 12 providing horizontally aligned rests 15 for the ends of a mandrel 21 to which the wheel 18 may be coaxially secured, the stand having a lever 17 pivoted thereto for lifting the wheel assembly, by the mandrel, to allow the mandrel to roll on to its rests 15, and coacting means 26, 23 on the stand and mandrel providing for location of the wheel in different angular positions for re-grooving operation on corresponding arcs of the tread. As shown, the rests 15 are formed by concavities on the tops of a pair of spaced, inverted V-shaped stanchions 11, 12, and the lever 17 is a U-shaped member pivoted near the free ends of its limbs to the two stanchions. The extreme ends 24 of the lever limbs extend beyond the pivots 16 and are formed with depressions into which the ends of the mandrel will roll on raising of the lever, the depressions being positioned relative to the pivots 16 so that the mandrel is lowered on to the rests 15 on further raising of the lever. The mandrel has a head 22 at one end, and a ratchet wheel 23 at the other, the ratchet wheel 23 cooperating with a spring-pressed plunger 26 on the stanchion 12 for stepped rotation of the mandrel. The wheel assembly may be bolted to a radial flange 20 on the mandrel. As an alternative to the ratchet wheel 23, a disc having a recessed periphery may be used.

Abstract: 1311119 Valves ACF INDUSTRIES Inc 6 July 1970 [29 Sept 1969] 32647/70 Heading F2V Sealing of a valve spindle 50 with respect to a valve housing 12, is effected by means of two resilient sealing members 64, 66 one disposed on each side of an annular flange 58 which projects inwardly into the spindle-accommodating bore in the valve housing. Sealing member 64 is retained against the flange 58 and is forced into engagement with the screw thread on the spindle by means of a gasket 72 which is screwthreaded on the spindle. Sealing member 66 is retained against the flange 58 by means of a flange 68 carried by the spindle. The seals, when assembled, are deformed to have differing inner and outer peripheral widths thereby enhancing the sealing effect by utilizing differential pressure forces. The seal-contacting surface of gasket 72 is made with a plurality of projections or grooves; (Fig. 7, not shown), to so ensure that the adjoining sealing member 64 moves with the gasket 72 upon the spindle being turned. The spindle may be used to operate a ball valve, (Fig. 1, not shown) in which case the ball is accommodated in a pipe-like housing into the ends of which fit seat-carrying threaded pipes.

Abstract: 358,757. Transformers. WESTING- HOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Hyde, H. G. ; 20, 2nd Street, Masury, Ohio, U.S.A.) Nov. 1, 1930, No. 32891. Convention date, Nov. 1, 1929. [Class 38 (ii).] In a constant current transformer of the type in which the primary and secondary windings are relatively movable under the influence of the repulsive forces developed between them, guiding means are provided for maintaining the axis of the movable winding parallel to the axis of the core leg along which it moves. In one arrangement, Fig. 1, the movable winding 4 is supported in a cradle 19 suspended at one end by members 21 from a pivoted beam structure 27 carrying an adjustable counterweight 28. The cradle is rigidly secured to the members 21 and is caused to move in an arcuate path so that the axis of the winding remains parallel to that of the core leg 11 by means of a roller 8 co-operating with an arcuate guide 9 having a radius of curvature equal to the distance between the pivotal point of the beam structure and the point at which the members 21 are attached. In another arrangement, the guiding means comprises a pair of links pivotally secured to the members 21 and to the core frame so as to provide a parallel motion arrangement. In a further arrangement, Fig. 4, in which both windings 42, 46 are adapted to move, the lower winding is suspended at one end from a pair of rocking levers 54 pivoted at 52 and at the other end from a rocking lever 56 pivoted at 53. The upper winding is similarly suspended from the opposite ends of the levers 54, 56, and its movement is guided by a link 73 pivotally secured to the cradle carrying the winding and to a bracket 72 provided on the core frame.

Abstract: 1365050 Non-spill battery vents TELEDYNE Inc 10 July 1973 [6 Oct 1972] 32929/73 Heading H1B A non-spill vent plug (e.g., for lead-acid aircraft batteries) has a threaded body portion divided into upper and lower chambers 16, 18, by a stepped shoulder 14 and provided with a snap-fit vented cover 20. A frusto-conical weight 32 normally rests on the shoulder and is adapted to pivot about its edge 34 when the plug reaches a certain tilt angle. As it pivots it raises the attached stem 40 and pulls the frusto-conical valve surface 46 against the sharp-edged seating. The valve stem is unitary and has a rigid lower portion 45 (achieved by the provision of three integral equispaced ribs 48) and a more flexible middle portion 43; this ensures that the stem moves cleanly through the aperture 24. The upper end of the stem has integrated collars 44, 42 to lock the stem to the weight when the stem is pushed and snapped into the base 38. The underside of the weight may be grooved to assist venting in the normal operative position. In case the gas pressure rises dangerously when the valve is closed the widened head is made of such shape and flexibility that it may be squeezed through the aperture 24 by the gas pressure and the stem and attached weight and the cover 20 blown out of the plug. The stem 40 may be of butyl rubber and the size of the head made such that it acts as a spray barrier during normal venting.
