Title: Improvements in and relating to electric induction heaters
IPC: H05B6/02
Filed: 1955-10-19
Abstract: 787,874. Heating by induction. DEUTSCHE EDELSTAHLWERKE AKT.- GES. Oct. 19, 1955 [Oct 20, 1954], No. 29902/55. Class 39(3) [Also in Group XXX] An induction heater comprises a non- metallic work chamber 3 preferably of silicon carbide, the chamber being surrounded by a work coil 1 which may be of copper tubing and water-cooled. The reduced thickness of the wall of the chamber at 5 and the gap between this portion and the faces 2a of the workpiece permit a heat loss of a similar order to that resulting from the contact of the thicker portion 4 of the chamber with the workpiece, and more even general heating of the workpiece results. In a modification, Fig. 2 (not shown), the thickness of the chamber wall is further reduced such that the heat loss in this region corresponds to additional heat loss by a liquid-cooled conveyer or a conveyer formed of ceramic. Alternatively, cooling means may be provided in the chamber wall opposite the conveyer. In a further construction, Fig. 6, a chamber shell 3 may be made of mica or asbestos and have liner portions 19 of silicon carbide on which the workpiece is supported. Fig. 7 shows a portion of a reciprocating conveyer of ceramic which has apertures 21 to allow scale from the workpiece to fall through on to the shell from where it is swept out of the chamber by ribs 20 on the return stroke of the conveyer.

Title: Improvements in hydraulic servo-mechanism for a reheat-type steam turbine intercept valve
IPC: F01K7/24
Filed: 1957-09-25
Abstract: 832,648. Turbines. GENERAL ELECTRIC CO. Sept. 25, 1957 [Oct. 22, 1956], No. 30074/57. Class 110 (3). [Also in Group XXIX] In a re-heat-type steam turbine power plant 1, 2 having an emergency speed control system 8, 8a, 8b, controlling main and re-heat stop valves 1b and 10 respectively, and a preemergency speed control system 12-15 controlling the intercept valve 9, the latter system has a control arrangement which does not effect operation of the intercept valve by the pre-emergency system during intercept valve movements below a preselected rate corresponding to a preselected rate of turbine acceleration, but which rapidly closes the intercept valve for accelerations above the preselected rate. Water from condenser 4 is pumped at 5 to a primary boiler 6a and steam passes the main stop valve 1b and a main control valve 1a controlled by governor 7 to a high pressure turbine 1. The steam then passes to a re-heat boiler 6b, the re-heat stop valve 10 and the intercept valve 9 to a low pressure turbine 2 connected to the condenser. Should the speed increase slowly to 101% of rated speed, a governor 11 moves piston valve 24 downward to shut-off oil pressure at 17 and open drain port 18 so that spring 23 moves piston 21, piston valve 15a and dashpot piston 13b downward, the latter moving at a speed below the maximum permitted by the dashpot needle valve 13j, so that piston valve 14a abuts stop 14h and oil acts on piston 14d to keep a drain valve 14g closed. Downward movement of valve 15a releases oil pressure from piston 15c so that it closes the intercept valve 9 at a 105% of rated speed. Should the turbine accelerate at a rate greater than the permitted rate of descent of the dashpot piston, downward movement of piston 21 rocks lever 30 about fulcrum 30b on the dashpot piston and lifts valve 14a to drain oil from piston 14d and open drain valve 14g whereby piston 15c quickly closes the intercept valve 9. If the speed exceeds about 110%, the emergency speed governor 8 trips and closes valves 8a, 8b, 1b and 10 to shut down the turbine.

Title: Process and apparatus for the thermal treatment of threads
IPC: D02J13/00
Filed: 1977-07-18
Abstract: Compression-crimped synthetic silk consisting of thermoplastic is subjected in thread-plug form to thermal aftertreatment. For this purpose, an aftertreatment drum (14) of adjustable rotational speed and at least one compression chamber (10) are used. A delivery unit (11) of adjustable rotational speed, arranged between the compression chamber or compression chambers and the aftertreatment drum, serves for conveying the thread plug or thread plugs of crimped multifilament synthetic silk, formed in each compression chamber, out of the compression chamber or compression chambers and, after passage through a free zone, towards the aftertreatment drum. Once arrived there, each continuously delivered thread plug runs in an approximately tangential direction onto the gas-permeable casing of the rotating aftertreatment drum cylinder and is transported through the aftertreatment zone by the latter in the form of helical thread-plug turns lying closely to one another and free of radial pressure. The thread material is either heated or cooled. The gaseous treatment medium flows through the helical thread plug turns of the treatment material in the radial direction. The opening of the thread plug or thread plugs to form crimped synthetic threads takes place at the end of the aftertreatment drum. A tension-free, uniform thermal treatment of the synthetic silk delivered at a high feed speed, along with a sufficient dwell time, is made possible in this way. <IMAGE>
