IPC: F03B3/18
Filed: 1964-03-24
Abstract: 1,042,424. Hydraulic turbines. T. Z. LITOSTROJ. Feb. 26, 1964 [March 29, 1963], No. 8037/64. Heading F1F. [Also in Division G3 and El] A closure 1 in the lateral outlet of a water turbine, comprises parallel closures 2 connected by links 5 to a rod 6, the rod being connected to pistons 7 of servomotors 8. The closures 2 are pivoted such that flow through the closures acts to provide a force tending to open the closures. The turbine is provided with a blade setting ring 13 connected to pistons 12 of servomotors 11. A pump 17 provides control fluid through a line 16, having a relief valve 20 and through throttle 18 to a line 10 which leads to the servomotors 8 and 11. The opposite ends of the servomotors 11 are connected by a line 23 to an electrically actuated control valve 21 which can connect the line 23 to a reservoir 25 or the line 16. Under normal condition, the valve 22 is actuated in response to changes in load to cause actuation of the blade ring 13, the throttle 18 allowing sufficient flow to prevent a lowering of pressure in the conduit 10. With a sudden increase in load, the line 23 is connected to exhaust to the reservoir 25 and the fluid acting on the closures 2 opens these closures and actuates piston 7 to transfer control fluid to the pistons of servomotors 11 to close the blade ring 12. With decrease in load, control fluid flows to line 23 to open the blade ring 12 and the control fluid is exhausted through non-return valve 18 by actuation of the pistons of servomotors 11. In a modification the servomotor 8 are actuated directly by the valve 22 and are not hydraulically connected to the servomotors of the blade ring.

Patent YU-42936-B (YU)
Title: Arrangement for controlling a system for information transfer with light wave conductors
Inventor: CHRISSTIANSEN H
IPC: H04B10/00
Filed: 1978-11-17
Abstract: In the transmission of messages on lightwave conductors, upon the rupture of such lightwave conductors, dangerous rays can occur that cause eye damage. Therefore, an installation is proposed that, upon the rupture of a lightwave conductor, communicates this rupture to the transmitting station via an auxiliary or return line. This communication causes the transmitter to transmit only pulsed messages in the direction of the rupture location, so that the radiation occurring is harmless. Further, the installation sees to it that upon reception of the pulsed message in the receiver following the rupture location, a return notice is transmitted to the transmitter concerned, so that the transmitter is caused to again switch the full signal output through.

Title: Method for the preparation of melamine
Inventor: HINSBERG J
IPC: C07D251/60
Filed: 1980-04-22
Abstract: An improved method for the preparation of melamine by the conversion of urea and/or thermal decomposition products thereof. The urea and/or thermal decomposition products are converted to melamine in the presence of a gas mixture containing ammonia and carbon dioxide in a reaction zone containing a fluidized bed of catalytically active material. Melamine is desublimated from the melamine containing gas mixture in a desublimation zone by a dry-capture method leaving a desublimator off-gas mixture of ammonia, carbon dioxide and gaseous impurities. A major portion of this desublimator off-gas mixture is compressed and recirculated to the reaction zone as fluidizing gas for the bed of catalytically active material, without intervening treatment to remove gaseous impurities from the desublimator off-gas.

Title: Apparatus for joining profile sections
Inventor: DRAGON HORST
IPC: B29C65/50
Filed: 2000-05-24
Granted: 2004-04-21
Abstract: A method and apparatus for joining the ends of two profile sections ( 5, 6 ) such as two sealing, trimming or finishing strips for use in motor vehicle body construction, is shown. The two profile sections ( 5, 6 ) are clamped in respective retaining devices ( 18, 20 ) and a length of heat-responsive foil-like material ( 24 ) is unwound from a roll ( 22 ) into a position between the facing ends of the profile sections. Heaters ( 26-32 ) carried by a heater unit ( 34 ) are then moved into position between the ends of the profile sections ( 5, 6 ) and the foil ( 24 ). The outermost heaters ( 26, 30 ) heat the ends of the profile sections, and the innermost heaters ( 28, 32 ) heat the foil. The heaters ( 26 to 32 ) are then withdrawn, and the two retaining devices ( 18, 20 ) are then moved towards each other so as to move the ends of the two profile sections into contact with opposite sides of the heated foil ( 24 ) which thus heat-bonds the ends of the profile sections together. The retaining devices ( 18, 20 ) are then opened to release the joined profile sections. The heaters ( 26 to 32 ) are non-contact type heaters to avoid contaminating the foil or the ends of the profile sections. The use of the separate heaters allows the foil ( 24 ) to be heated to a temperature which is different from that of the ends of the profile sections, to achieve optimum bonding.
