Title: Improvements in or relating to devices for automatically starting and stopping steam or gas turbines
Inventor: SIROKORAD JURIJ
IPC: F01D21/00
Filed: 1969-04-09
Abstract: 1,270,303. Programmed control of turbines. PRVNI BRNENSKA STROJIRNA NARODNI PODNIK. April 9, 1969, No. 18147/69. Heading G3N. [Also in Division F1] A device, for automatically starting and stopping a steam or gas turbine, comprises sensors, monitoring the state of auxiliary controls of the turbine, which are connected through relays so that a main control for the turbine is operated only when each relay is in a state indicating the normal operation of the respective auxiliary control. As shown, the device for automatically starting a turbine 33 is initiated by closure of a switch 1 which energizes an oil pump 2, opens drain valves 3 for the casing, a primer valve 25, the live steam piping, and a condenser cooling water valve 32. On completion of these operations their serially connected sensors, and those for thrust protection 20 and axial travel 21, energize a relay 5 which engages a barring motor 19. Rotation of the motor 19, through a sensor 6, connects a turbine backpressure heating sub-programmer 8, controlling a by-pass valve 9, responsive to turbine casing temperature. At a predetermined temperature valve 9 is fully open and a sensor 11 energizes a relay 12 controlling a main back-pressure slide valve 10. When valve 10 is fully open a sensor 13 energizes a relay 14 operating a switch 15 which increases the oil pressure in the turbine protective system and fully open control valves 22. A sensor 16 is closed by the valves 22 and the switch 15 and energizes a relay 17 initiating a sub-programmer 18 for the sequential increase of turbine speed, as sensed by a tachometric generator, through a valve 25. At the operational speed of the turbine the primer valve 25 opens completely, and a speed control, not shown, automatically takes over control by adjustment of throttle valves 22. A sensor 26 is closed by the valve 25 and, through a relay 27, shuts down the starting device. Turbine shut down by a sub-programmer 31 is initiated by a switch 28, which closes control valves 25, 22, drain valves 3, by-pass valves 9, 10 cooling water valves 32, and shuts-down the barring motor 19 and the auxiliary oil-pump 2. Sensors 29 then energize a relay 30 which actuates a switch 28 closing down the stopping device.

Title: Improvements in or relating to the removal of selenium from unsaturated aldehydes obtained by selenium catalyzed oxidation of olefines
Filed: 1949-07-14
Abstract: In the manufacture of unsaturated aldehydes by the oxidation of olefines in the gaseous phase with molecular oxygen over heavy metal compounds containing contact materials in the presence in the reaction zone of elementary selenium, the gaseous reaction mixture issuing from the reactor is passed over gas adsorption charcoal for removal of selenium and selenium compounds from the reaction mixture before it is released to the atmosphere. Preferably, the unsaturated aldehyde is removed from the gaseous mixture before bringing the latter into contact with the charcoal. If desired, the selenium content of the gas mixture may be reduced by cooling the mixture, thereby depositing crystalline selenium prior to the charcoal treatment.  Increased adsorption results when deposition of water on the charcoal is prevented by warming the charcoal.  The adsorped selenium may be recovered by heating the charcoal to volatilize the selenium, by passing fresh gas reaction mixture over the charcoal at elevated temperature prior to the mixture entering the reactor, or by converting the selenium into a soluble compound and extracting with a suitable solvent, e.g. by treating with chlorine in presence of steam and then washing with water.  In examples, a gaseous mixture of air, propylene and selenium is passed over copper-oxide/alumina at 320 DEG C., the issuing gaseous products washed free of acrolein and then passed through an adsorbent and data is given showing the superiority of activated coconut charcoal over silica gel and activated alumina in the retention of residual selenium.  The oxidation of isobutene to methacrolein is also mentioned. Specifications 625,330, 648,386, 655,210, 658,179, 678,557, 694,353, 694,354 and 694,362 are referred to.

Abstract: 813,664. Feeding sheets. ZEUTHEN & AAGAARD, A. S. June 13, 1957 [June 19, 1956], No. 18734/57. Class 100(1) In apparatus for feeding and registering sheets in a duplicating or other machine which includes at least one driven feed roller 1, there is associated with the roller 1 a co-operating drop-roller 3 and a register roller 2, the roller 2 being yieldable relative to the roller 1, and the arrangement is such that first the roller 2 contacts the stationary roller 1, a sheet 4 is fed so that its front edge is engaged and registered by the rollers 1, 2, the roller 3 then presses the sheet on the roller 1, and the roller 1 is driven to feed the sheet towards th machine. As shown, the rollers 2, 3 are carried on one arm 6 of a bellcrank 5, 6 pivoted at 11 and provided with a roller 12 in engagement with a rotating cam 13. The shaft 7 of the roller 2 can move in a slot in the arm 6 against the action of a spring 10. The two arms 5, 6 may be connected by spring or other resilient means to ensure that the rollers contact under suitable pressure and allow the arms 5, 6 to yield relatively to each other. The feed roller 1 is driven clockwise from the machine by means of a cam-actuated lever having a toothed segment thereon which engages a pinion on the shaft of the roller 1. The toothed segment rotates the roller 1 in timed sequence with the machine and for a specified period: when the roller is released it is rotated reversely to its starting position by means of a spring which is wound up during the positive drive of the roll. The shape of the cam which rocks the toothed segment may be such that the roller 1 is rotated slowly at first, and gradually accelerated to maximum speed. The starting position of the roller 1 may be determined by a member thereon which abuts an adjustable stop member. This will cause printing to be effected in different positions on the sheet.
