Title: Machine for the fabrication of hardenable foamy plastic
IPC: B29B7/74
Filed: 1954-03-05
Abstract: 752,121. Mixing appliances. SPUMALITANSTALT. March 5, 1954 [March 12, 1953], No. 6591/54. Class 86. [Also in Group XXI] A machine for the continuous production of hardenable foamy plastic consists of a coarse foam producer 24, Fig. 1, wherein compressed air from a pipe 25 passes upwardly through a horizontal fine mesh sieve 27, Fig. 5, to combine with a foam forming liquid possessing catalytic properties which is continuously supplied through a duct 26 to form a thin layer over the sieve 27, the coarse foam produced thereby passing into a horizontally elongated agitator unit 1, wherein a plurality of rotating horizontally elongated wire bristle rollers 8 closely spaced from each other and from the wall of the agitator unit reduce the coarse foam to fine foam and mix the fine foam with liquid synthetic resin forced through a pipe 32, which resin immediately begins to harden under the catalytic action of the foam. The foamy plastic is removed from the agitator unit while it is still not fully hardened by a rotating impeller 37 which delivers through a pipe 38. The rollers 8 consist of diametrically split tubes 12, Fig. 3, attached in pairs to shafts 11 by clamp rings 13 and the bristles 14 are formed in pairs bent from lengths of wire which are inserted from the interior through holes in the tubes and are secured by welding or screwing their connecting pieces 15 to the inside of the tubes. As described four wire bristle rollers are provided which are driven by means of a belt, Fig. 4 (not shown) and pulleys such as 19, 20 on the outer ends of the shafts 11 so that each roller rotates in the same direction as its diagonally opposed roller which is opposite to the direction of rotation of the pair of adjacent rollers. Each roller rotates at the same speed as its diagonally opposed roller which is different from the speed of rotation of the pair of adjacent rollers. The rear section of the agitator unit into which the liquid synthetic resin is added to the foam, is separated from the preceding portion of the agitator unit by discs 5 on the rollers and a baffle plate 6 on the container wall closely spaced from the discs 5, or by a rigid transverse wall with one or several openings therein. The liquid synthetic resin is supplied through a rapid action needle valve, Fig. 6 (not shown), which can be closed to prevent the foam from entering the feed line 32 of the liquid synthetic resin. In an alternative arrangement the rollers may be driven through a train of gears. The rollers may rotate at different speeds from each other.

Title: Improvements in and relating to heavy-current electric switches
IPC: H01H1/54
Filed: 1942-05-16
Abstract: 551,432. Switches partly electromagnetic. BRITISH THOMSON-HOUSTON CO., Ltd. May 16, 1942, No. 6661. Convention date, May 20, 1941. [Class 38 (v)] A heavy-current switch, suitable for on-load, transformer-tap changing, is so arranged that the electrodynamic effect of the current-loop reinforces the contact-pressure instead of tending to throw the switch open. The arm 8 is pivoted by a pin and slot connection to a bracket 7 and operated by a member 12 separated from the pivot and contact 9 by distances A, B, respectively, such that A is greater than B. The effect of the loop on the part of the arm between 12 and the pivot is thus greater than that between 12 and the contact 9 and assists the wear-accommodating spring 13 in reinforcing the contact-pressure. In a modification, Fig. 2 (not shown), the'spring acts between a fixed abutment and a point on the arm in line with and behind the contact. The later is connected to the bracket 7 directly by a braid 10 and conductor 11.

Abstract: 987,264. Steam turbine plant. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Feb. 23, 1962 [Feb. 23, 1961], No. 7160/62. Heading F1T. [Also in Division G3] A control system for a steam turbine 23 fed through a control valve 13 and quick-acting cut-off valve 27 from a steam generator 12 of boiling-water reactor type comprises servopistons 20, 28 for the valves 13, 27, a servopiston 24 for actuating a valve 14 which by-passes steam to an injection cooler 29 and condenser 30, a valve actuated by a governor 22 for controlling the servopiston 20 and for applying a signal to the upper side of a piston 18 which actuates a valve controlling the servopiston 24, and a valve actuated by a bellows 16 responsive to steam pressure and controlling the servopiston 20 and, through a spring 17, influencing the valve that controls the servopiston 24. A by-pass control 26 and a starting control 25 are adjustable by remotely controlled motors M to control the servopistons 24, 20 independently of each other before the working pressure of the system has been reached. If the installation is started up with the controls 25, 26 closed the turbine valve 13 does not open until the working pressure has been reached to open the valve operated by the bellows 16. Thereafter,. the turbine valve 13 is controlled by the governor 22 which also controls the valve 14 through the piston 18 in such a manner that when the valve 13 is moved towards closure due, e.g., to decreased load on the turbine, the opening of the by-pass valve 14 is increased. The by-pass valve is also opened in response to operation of the control 31 of the quick-acting cut-off valve 27. Any tendency for the steam pressure to exceed its working value causes the bellows 16 to open the by-pass valve 14. The control valves for the servopistons are connected downstream of restrictions 32, 33, 34, 35 in conduits supplied from a pressure source pi v , and control discharge to outlets O. The governor 22 and bellows 16 are adjustable by remotely controlled electric motors M. The pressure that actuates the servopiston 24 may also control the reactor.
