Abstract: 562,835. Brazing cycle &c. frames. COVENTRY-EAGLE CYCLE & MOTOR CO., Ltd., and WOODMAN, A. C. April 5, 1943, No. 5391. [Classes 83 (ii) and 83 (iv)] In making tubular structures such as cycle and motor cycle frames, the ends of the members are first loaded with brazing material, then assembled in their relative positions by lugs or brackets and structure pivotally mounted and the joints are then passed in succession through a brazing furnace or muffle by rotating the structure on its mounting. The tubes b, c, d at the ends which fit in the bottom bracket h are provided with inner and outer flanged plugging discs k between which the brazing material is contained. The end of each member is drilled at i to enable the brazing material to find its way into the joint. The tube a is provided with a single plugging disc k at the end which is inserted in the lug e at the top of the seat pillar tube. The parts after assembly are clamped between pairs of bars or plates q. arranged so that the clamping bolt r is equidistant from the several joints of the frame. The frame may then be rotated by hand or power about the axis r in a bracket arranged near a brazing furnace so as to braze the joints in turn. In a modification, brackets s in which the clamping plates q are mounted are secured at intervals on an endless conveyer t so that the frames can be passed through a series of furnaces u. As one frame leaves a furnace it is turned on the axis r to present another joint to,the next furnace. The turning may be effected automatically by fixed projections arranged alongside the conveyer and engaging the frames. The plugs may be replaced by cartridges m containing brazing material and closed at the open end by caps n, the cylinders having an annular groove formed with holes o at opposite sides thereof.

Abstract: 167,799. Marks, E. C. R., (Landers, Frary, & Clark). Feb. 23, 1920. No Patent granted (Sealing fee not paid). Electric hand-irons. -A thermally - released circuit-breaker for controlling the current to an electrically heated device such as a laundry iron consists of a pair of fixed contacts in the heating circuit normally bridged by a contact carried by a spring contactmember provided with inclined lateral shoulders which engage with correspondingly inclined shoulders on a pair of bimetallic spring-strips whereby the contactmember is held in the closed position against its return action until the overheating of the device causes the deflection of the bimetallic strips out of the retaining position. The circuit-breaker as a whole is mounted upon a plate detachably secured to the device so that it may be electrically adjusted independently of the device. As applied to a laundry iron, Figs. 7 and 8, the spring contact member 54 carries an inclined steel plate which co-operates with a similarly inclined set screw 63 on the bimetallic bar 60. The free end of the member 54 carries a roller contact 57 having some free movement in a slot so that when the contact member is released by the bimetallic strip it strikes the roller and withdraws it rapidly from bridging engagement with the contacts 52.

Inventor: LINDLEY PETER ARNOLD
IPC: G21C15/08
Filed: 1958-02-20
Abstract: 859,799. Nuclear reactors. GENERAL ELECTRIC CO. Ltd. Feb. 19, 1959 [Feb. 20, 1958], No. 5551/58. Drawings to Specification. Class 39(4). In a graphite-moderated gas cooled nuclear reactor, periodic annealing of the graphite core to release the Wigner energy is avoided by maintaining the core at a temperature above that at which self-annealing takes place. A fraction of the hot gases leaving the reactor fuel channels is reintroduced into the core structure, through which it passes by means of the Wigner gaps between the graphite blocks. The temperature of the core is controlled by regulating the rate of flow of the reintroduced hot gases, which may be introduced at the control rod channels or into similar channels between the control rods.

Title: Improvements in or relating to rotary cutters
IPC: B23C5/06
Filed: 1945-03-08
Abstract: 589,928. Securing milling-cutters &c. on shafts. DEFIANCE MACHINE WORKS, Inc. March 8, 1945, No. 5740. Convention date, Oct 18, 1944. [Class 80 (ii)] [Also in Group XXII] Relates to cutters and boring heads having a shank for connection to the machine spindle and consists in mounting the cutter body for limited rotation on the shank with interposed resilient means for suppressing rotational vibration. Cutters 7, Fig. 3, are secured by screws to a circular body 6 flexibly mounted with limited rotation on a stub-shaft 11 provided with a tapershank 10 for attachment to the spindle of the machine. Radial arms 9, Fig. 2, transmit the drive to hydraulic buffers 8 secured to the body 6 wherein pistons 21, Fig. 4, are disposed either side of the arms 9 in cylinders with springs 24 and 25 placed between the pistons and the arms, and the pistons and the end-covers respectively, the arms projecting into the cylinders through slots permitting limited relative movement. The enclosed spaces housing springs 25 are connected by a channel 27 and the whole filled with a hydraulic fluid, an adjustable screw 28 regulating the flow of fluid displaced by movement of the pistons. The springs transmit the drive through to the body 6 whilst torsional vibrations set up by the cutters engaging the work are minimised by the hydraulic buffers. In a modification the springs 24 are dispensed with and projections on the back of the pistons abut the arms 9, the channel 27 being enlarged at one end to accommodate a check-valve, a secondary adjustable port connecting the channel 27 with the rear of the check-valve. This arrangement provides extra facilities for damping vibration. A further modification employs pistons with split skirts urged open by internal springs to damp out vibration by frictional contact between the pistons and cylinder walls, thus obviating the hydraulic system. In the Specification as open to inspection under Sect 91, two alternative methods of providing resilient driving and damping means to replace the radial arms and buffer system are also described. In one method, the stub-shaft and body each have a sleeve concentrically mounted with a rubber-like ring bonded to both sleeves. In the second method, the back face of the body is provided with a friction ring against which a brake-shoe splined to the stubshaft is pressed by a series of springs, a torsion spring between the body and the shaft securing the resilient drive. The subject-matter does not appear in the Specification as accepted.

Title: Arrangement for short-time switching
IPC: H01H9/54
Filed: 1938-02-23
Abstract: 511,702. Switching systems. ZIEGENBEIN, W. Feb. 23, 1938, No. 5798. Convention date, Feb. 23, 1937. [Class 38 (iv)] [Also in Group XXXVII] In an arrangement for closing or opening an A.C. circuit for a definite number of half cycles, a rectifier is placed in series with a switch and the switch is operated during the blocking time of the rectifier. Fig. 1 shows two switches 5, 6 and two rectifiers 3, 4 controlling the A.C. supply to a consuming device 2. The valves are oppositely arranged so that " forward " current goes through the one branch 4, 6 and " backward " current goes through branch 3, 5. Switches 7, 8 may also be arranged as shown and are coupled with the switches 5, 6 so that they open just before the switches 5, 6. By this means the rectifiers 3, 4 only have to carry current just before the " break." Fig. 6 shows one form that the switches 5, 6 may take. A contact 42 urged in the direction of the arrow engages an insulating ring 41 with a gap 44. The ring 41 surrounds a gapped conducting ring 43 and both rings are rotated together so that at a predetermined time the contact 42 slips through the gap 44 and engages 43 and at a later time slips through the gap 45 and breaks the circuit just made. In a modified form, Fig. 7 (not shown), a contact is reciprocated into and out of engagement with the periphery of a rotating insulating disc carrying a contact sector on its periphery. In a modified arrangement, Fig. 3, the switches 5, 6 of Fig. 1 are each operated by the current flowing in the other branch of the circuit. On closing a switch 20, a circuit is completed to a coil 21 through the valve 4 causing contact arm 22 to be moved into the position shown and contacts 23, 24 to engageeach other to complete a circuit through the valve 3. The closure of the switch 20 also operates a time lag relay 26 which after a time interval connects lines 27 to a coil 28 which pulls the contact arm 22 back into its original position, breaking the circuit through the rectifier 3. A similar switch to 23, 24 may also be applied to control the branch 4 by current flowing in the branch 3, Fig. 4, (not shown).

Abstract: 1,046,148. Fluid-pressure servomotor systems. ROBERT SHAW CONTROLS CO. Feb. 10, 1965 [Feb. 12, 1964], No. 5833/65. Heading G3P. A valve controlling the flow of fuel to a burner comprises a housing having an inlet 12A an outlet 13A and a diaphragm 15A controlling flow through the housing when a cock 20A is opened. Inlet pressure also flows through conduit 22A and restriction 34A to a conduit 26A which is connected to a chamber 19A to act on the back of the diaphragm 15A. The pressure in conduit 26A is controlled by a reducing valve 30A, when an on-off valve 28 is opened, the fluid flowing through the valve 30A to the outlet 13A. The outlet pressure is sensed by an orifice 43 located in a fin 41 and since the pressure sensed is inversely proportional to the velocity of the fluid, the back pressure measured at 43 is less than the pressure normally which is measured at the circumference of the outlet and thus the loading on the diaphragm is reduced over known devices.
