Title: Shaft power output gas turbine plant
IPC: F02C9/18
Filed: 1974-07-25
Abstract: 1433467 Gas turbine engines-control GENERAL MOTORS CORP 25 July 1974 [6 Aug 1973] 32821/74 Heading F1G The invention relates to a gas turbine plant comprising a compressor 3, an air pre-heater 6, combustion equipments 8, and a turbine 12 which drives the compressor and an output shaft 15, the arrangement being such that the compressor may alternatively be driven by the output shaft. A valve 34 is disposed in the line 4 between the compressor and the air pre-heater, the valve being normally closed but being openable so that air passes directly from the compressor to the combustion equipment. The valve 34 is opened when the fuel supply is reduced so that unheated air passes to the combustion equipment and turbine. Alternatively or in addition a similar valve 36 is connected in line 37 leading to atmosphere whereby upon opening of the valve 36 air from the compressor is discharged directly to atmosphere. The plant shown is suitable for use in a road vehicle, the fuel supply being controlled by pedal 30; thus when the pedal is released and the turbine speed is above a predetermined value, the link 32 acts to close a contact 43, the contact 44 also being closed by a speed-responsive device 47 whereby the solenoids 39, 40 are energized to open the valves 34, 36. The power shaft may alternatively be driven by a separate power turbine but means are then provided to connect the power turbine to the compressor so that the compressor acts as a brake for example when the vehicle is descending an incline and the output shaft is being driven by the road wheels. The object of the invention is to reduce immediately the power of the turbine when the fuel supply is reduced to idling power since normally air would continue to flow through the air pre-heater and the heated air passing to the turbine would continue to generate power.

Title: Anti-glare device
IPC: B60J3/04
Filed: 1961-09-14
Abstract: 982,680. Double glazing. G. BECKMANN, and T. FAULHABER. Sept. 14, 1961, No. 32987/61. Heading E1R. [Also in Divisions Fl and G2] An antiglare device comprises, Fig. 2, at least two transparent panes 1 having a variable gap between them for receiving a liquid or gaseous light filtering medium and a suction pump 7 capable of effecting a reduction of pressure within the gap to withdraw the medium from between the panes and to reduce the distance between the panes. The pump in Fig. 2 is a diaphragm pump. The pump shown in Fig. 5 is a piston pump normally held by spring 32 in a position in which the panes are pressed together and the liquid is in chamber 34. When a current is passed through coil 27 the piston moves to the left forcing the liquid between the panes. The piston stroke may be limited by means of screw 35 and the operative parts of the panes by means of clamps 36 to produce a liquid line at 37. When the invention is applied to a large window the panes are inserted into a frame with their upper edges straight or only slightly curved and their lower edge considerably curved to increase their resistance to further bending when liquid enters the gap. A third pane may be provided behind the others and the intermediate gap filled with a suitable gas to act as a heat insulator. For smaller and horizontally installed windows the panes of glass are thickened to withstand the weight of the liquid. The transparent panes may be mounted on either side of a spacer, with a sealing pad on the outside of each pane between it and a frame; with a sealing pad round the edges of the frames; in a W-shaped or V-shaped, or T-shaped gasket; with a tubular gasket arranged in grooves in the inner surfaces of the frames. The edges of the panes may be bent outwards at their edges. The panes may also be fixed in a U- shaped frame by means of a liquid which is forced between the frame and the panes and then set. The light absorbing characteristics of the liquid may also be changed by means of an electric current or a magnetic field if a suitable liquid is chosen. The liquid may also be coloured. The panes may be polarisers or filters. Metal particles can be added to the liquid which have the property of becoming regularly aligned when subjected to ultrasonic radiation to decrease dazzling when used in a car. The ultrasonic radiation may be controlled automatically by light from oncoming cars &c. An aromatic substance may be placed between the panes to detect for leaks.

Record cards or the like in a stack V are separated sequentially from the bottom of the stack by a friction roller 1 in staggered overlapping relationship and fed through a throat S to a pair of feed rollers 2 which have a higher peripheral speed than the roller 1, and the rollers 2 feed the cord to a second pair of rollers 3 which have a higher peripheral speed than the rollers 2. The cards may be fed at higher speeds by further sets of rollers. Preferably, the roller 1 is spaced from the trailing edge of the lowest card by a distance of one quarter of the card length. The distance between rollers 1 and 2 is equal to one card length, and the distance between the rollers 2 and 3 is three quarters of a card length. Thus, the rollers 3 are spaced a card length from the throat S. Preferably the rollers 2 rotate three times faster than the roller 1, and the rollers 3 more than four times faster than the roller 1. The separator roller 1 engages the bottom card through an opening in the base of the card magazine, and the throat S below the front wall is equal to the thickness of two cards. In operation, before the first card has left the magazine it is gripped by the faster moving rollers 2, and assists the withdrawal of the next card by frictional engagement therewith.

Title: Improvements in the purification of gases obtained by cracking
IPC: C10K1/18
Filed: 1957-10-28
Abstract: <PICT:0818127/IV (b)/1> A process for purifying gases, and in particular acetylene, which have been obtained by cracking hydrocarbons in the liquid phase; from carbon black, hydrocarbon mist, and unsaturated polymerizable compounds, especially higher acetylenes by scrubbing in a plurality of consecutive washers according to the parent Specification, comprises separating the bulk of the carbon black at a temperature lying above the dewpoint of the water vapour contained in the cracked gas and removing the water vapour by condensation by means of indirect cooling prior to the following scrubbing.  In a preferred embodiment a crude hydrocarbon oil of a boiling-range of 50 DEG  to 400 DEG  C. is cracked in the plant described in Specification 364,418, [Group IV], represented as vessel 1 and the cracking gas leaves this vessel at a temperature of 150 DEG  C., the dewpoint of the steam contained therein amounting to 67 DEG  C.  In the first scrubber 2, the gas is cooled to a temperature of 70 DEG  C. and the carbon black content reduced to 75 milligrams per cubic metre.  The liquid hydrocarbon laden with carbon black which is used as washing liquid is centrifuged out from the gas together with the condensed constituents of the hydrocarbon vapour contained in the cracking gas in cyclone separator 3 and supplied to the pump receiver 4, whence it passes through the pump 5 and the cooler 6 back to the scrubber 2.  The cracking gas freed from the bulk of the carbon black is led from cyclone 3 into the indirect water cooler 9 where it is cooled to 21 DEG  C., about one-quarter of the remaining carbon black is precipitated, and the mixture is forced by a gear pump 11 through a Scheibler filter 10 where the carbon is retained.  Water is separated in vessel 12 and removed through pipe 13, and the hydrocarbons returned via pump 14 to the reaction vessel. The cracking gas then enters a venturi washer 16 and column 17 where it is washed with hydrocarbons which are to be cracked, which enter through pipe 22.  The cracked product leaves through the line 23 at a temperature of 21 DEG  C. and contains 6.8 per cent by volume of acetylene.  Specification 655,038, [Group XII], also is referred to.

Abstract: 1385198 Testing ferromagnetic material BRITISH IRON & STEEL RESEARCH ASSOCIATION 14 July 1972 [16 July 1971]  33552/71 Heading G1N The metallurgical phase, and/or temperature of a ferromagnetic material is detected by passing an alternating magnetic flux through the material and measuring the flux as modified by the material indicative of the magnetic properties of the material. The testing apparatus 8 is disposed below a steel strip 5 from a hot strip mill and includes an H-shaped magnetic core 10 mounted in a chamber 12 through which cooling water flows. A field winding 18 energized from A.C. source 30 produces an alternating flux passing through strip 5 via feet 38. The flux is modified by the magnetic properties of the metal strip 5 and causes a voltage VI to be generated across coils 22, 24 wound so that equal fluxes passing through the parts of the upright 26 from cross bar 20 produce a zero voltage across terminals 29. V 1  is integrated in box 40 to produce a signal representative of the magnetic induction B and a signal V 2  represented of the field H produced by coil 18 is developed across resistor 34. B, H, Hc, Br, Bm and Á are obtained from the computer 40 and the hysteresis loops calculated, they may be displayed on an oscilloscope. Various graphs of Bm, Br, dBm/dt dBr/dt versus temperature, H, B versus time and phase diagrams for various cooling rates are described Figs. 4-8 (not shown) from which phase transformation and temperature of the strip 5 can be deduced and signals obtained to control the cooling of the strip to produce a particular phase of the material of the metal strip.

Title: Method and apparatus for maintaining the edge of a moving birefringent transparent or translucent film in a predetermined position
IPC: B65H23/02
Filed: 1956-11-02
Abstract: 801,303. Automatic strip position control systems. CELLOPHANE INVESTMENT CO., Ltd. Nov. 2, 1956 [Nov. 4, 1955], No. 33554/56. Class 38 (4). The lateral position of a birefringent film (i.e. one which affects the polarization of the light passing through it) is maintained by monitoring the intensity of a polarized light beam projected across the edge of the film and providing means by which the variations control the position. In one embodiment, Fig. 3, a lamp 15, having a special compact filament 16, projects a light beam across the edge 22 of the film 21 on to a photo-electric cell 23. It passes through an infra-red filter 18, is polarized by a sheet of " Polaroid " (Registered Trade Mark) 19 then passes through aperture 17 to the film's edge. A further sheet of polaroid 20 acts as an analyser, its output passing through to the photo-cell. Although the planes of polarization of the sheets 19 and 20 may be at any angle, they are preferably either parallel or at right angles. The photocell output depends on the luminous flux affected by the film and therefore on the film position relative to aperture 17. Control of the film position may be by a reversible motor driving an endless screw to produce lateral motion of the film spool carriage, the motor being switched by a relay energized by the amplified photo-cell output. In a further embodiment, Fig. 1, instead of the polaroid sheets two plates of black glass are arranged at angles to the light beam to behave as polarizer and analyser.
