Title: Improvements relating to strapping machines
IPC: B65B13/02
Filed: 1939-08-24
Abstract: 536,797. Bundling machines. WILLCOX, T. W. J. Aug. 24, 1939, No. 15826/40. Divided out of 536,762. [Class 94 (i)] Apparatus for stopping boxes or other suitable' packages on a bundling machine, particularly in association with the device described in Specification 536,762, comprises a member carrying a stop which is moved away from the package by means synchronized with the device that trains a wire around the package, the stop being returned to a position that permits discharge of the package. The front of the package 32, is supported during the tying operation by rollers 11 which form a bridge between the table of the bundling machine and a conveyer by which the package is removed. As a package moves on to the rollers, it is arresed by a stop 27 carried by a rod 26 which is free to slide longitudinally, in a frame 10 that carries the rollers, against the pressure of a spring 29 that yields when the stop is struck by the package 32. There are two of the frames 10, and they are swung to one side in succession to allow a wire to pass around the package, as described in the Specification referred to. When this occurs the stop is returned to its initial position by the spring 29. The return of the frame 10 brings the stop below the package, a resilient connection between the stop and the rod 26 permitting the rollers 11 to return to their normal position. Another stop 28 similarly arranged and connected by a rod 25, arrests the package in a second tying-position, the stop successively engaging an end and then a side of the package as the frame 10 swings outwards and inwards. The longitudinal movement of the rods 25, 26 may be transmitted by means of a Bowden cable to a device which sets in motion the tying- mechanism, so that the mechanism is set in operation each time a packet makes contact with a stop.

Title: Nuclear Power Plant
Inventor: KAIPAINEN ARTO
IPC: G21D3/10
Filed: 1967-04-06
Abstract: 1,173,800. Nuclear power plant. ALLMANNA SVENSKA ELEKTRISKA A.B. 6 April, 1967 [7 April, 1966], No. 15865/67. Heading G6C. In a boiling light water reactor, excess steam is transferred from the reactor, through highspeed valves, to a water basin within the concrete enclosure vessel. The reactor supplies steam to the turbine of an electric generator and the valves are operated automatically, for an interval, in the event of a rapid fall of the generator load. The water basin also collects steam and water from the reactor in the event of a tube rupture within the reactor pressure vessel. The reactor output is controlled by absorber rods and by the adjustment of the rate of water flow through the core by a variable speed pump. Upon fall of generator load, the turbine speed rises and a corresponding signal is produced which opens the high speed valves, closes the steam supply valve to the turbine and opens a dumping valve which releases steam and water into the turbine condenser. Simultaneously, the rate of water flow through the core is decreased thereby reducing the reactor power.

Title: Improvements in and relating to electric traction control systems
Inventor: CARTER HOWARD FREDERICK
IPC: H01H35/14
Filed: 1954-05-28
Abstract: 777,467. Controllers. BRITISH THOMSON-HOUSTON CO., Ltd. May 26, 1955 [May 28, 1954], No. 15889/54. Class 38(3) [Also in Group XIX]  In a traction system, the rate of advance of a master controller is regulated so as to prevent excessive acceleration of the vehicle, two sensing devices being provided responsive to lower and higher acceleration values. respectively. The first device operates at a low value of acceleration when the vehicle starts, and may serve to close a circuit providing normal excitation of an eddy current brake which limits the rate of advance of the controller, as described in Specification 696,244. The device will open the excitation circuit of the brake durng coasting so that, when motive power is re-applied, the controller is advanced rapidly until its position corresponds with the speed of the vehicle. When the second device responds at a higher rate of acceleration, the controller is stopped completely by over-excitation of the eddy current brake. As shown, the first sensing device comprises an inverted pendulum with forward and reverse stops S<SP>1</SP>f, S<SP>1</SP>r, on either side of the vertical phase V<SP>1</SP> through the pivot axis r<SP>1</SP>. The extreme front position P<SP>1</SP>f in the direction of vehicle motion is the normal rest position of the pendulum. The second sensing device has both its front and rear stops. S<SP>2</SP>f, S<SP>2</SP>r, forward of the vertical plane V<SP>2</SP>. The force operating the sensing devices is a combination of forces due to vehicle acceleration and gravity, so that automatic compensation is afforded when the vehicle is on a slope. Specification 775,184 also is referred to.

Title: Improvements relating to machines for treating textile fabrics
IPC: D06C23/00
Filed: 1930-05-23
Abstract: 347,034. Feeding webs. MILHOMME, A., Ridgefield Park, New Jersey, U.S.A. May 23, 1930, No. 15977. Convention date, April 4. [Class 100 (i).] In a machine for producing moirÚ effects on fabrics, the moirÚ patterns are produced as the fabric is fed from a feed roll to a take-up roll and variable speed transmission mechanisms are provided to maintain a constant surface speed thereof and to control the speed of the pattern-making mechanism, the former mechanism being controlled by the varying size of the take-up roll. A roll 22, Fig. 6, draws fabric 21 past a tensioning roller 25 from a supply roll 20, the draw roll being driven by a motor 33, Fig. 3, variable speed gears 34, 36 and chains 41, 42, 44. Each variable speed gear comprises parallel shafts such as 51, 52, Fig. 5, carrying coned discs displaceable away from or towards each other by rotation of an oppositely-threaded rod 56 to vary the drive ratio. The gear 34 is manually controlled by a hand-wheel disposed outside the machine and associated with a pointer and scale to facilitate repetition of its settings, but the gear 36 is controlled automatically by a segment 38, Fig. 6, provided with a roller which is pressed against the fabric 21 on the draw roll 22 by a spring 69. As the fabric is wound upon the roll 22 the segment 38 is rotated and reduces the gear ratio of the gear 36 to keep the speed of the fabric constant. The tension roller 25, about which the fabric passes on leaving the roller 20, is mounted upon an arm 26 secured to a shaft 27 rigid with an arm 29, to which one end of a brake strap 28, passing around a drum 126 rotating with the roll 20, is secured, and with an arm 128 linked by a spring 127 and bar 129 to a screw adjustment controlled by handwheels 132, 133 at either end of the machine. When the draw roller 22 stops, the lever 26 is no longer urged forwards and the spring 127 applies the brake 28 stopping the roll 20.
