Filed: 1932-06-10
Abstract: 402,486. Mowing-machines. WILDER, H. H., Cattle Market, Reading. June 10, 1932, No. 16500. [Class 6 (iii).] A mowing-machine is provided with an elevator for collecting the cut crop, the elevator being arranged behind, and being drawn by the mowing machine the cutter bar of which is yieldingly connected to the front end of the elevator. The main frame 3 of the mower is carried upon wheels 1, 2, and has detachably secured to it two spaced bars 5, 6, to which a transverse draw bar 12 is adjustably secured, the draw bar carrying two rearwardly extending bars 10, 11, on which bearings 18, 19, for an axle 17 are arranged. The axle is supported by wheels 30, 31 and supports by bearings 20, 23, bearers 21, 22, carrying an elevator frame comprising vertical members 25 and inclined members 24. The elevator trough comprises wooden sides 26, 27 and a wooden bottom 28 : the cut crop is moved up the trough by tines 56 projecting from bars 55 that are secured to endless chains 52 passing over sprockets 51, 53 the shaft of the sprockets 51 being driven by a chain 47 from a sprocket 46 on the axle 17. Adjustable jockey sprockets 59 maintain the tension of the chains and plates 57 extending rearwardly from the bars 55 prevent the tines from tilting backwards. The front end of the elevator is supported by rollers 41, projecting from the members 24, engaging in slots 40 in members 35 carried at their rear ends by wheels 33 and detachably secured at their forward ends to the rear of the cutter bar by pivot pins 70.

Title: Improvements in or relating to coke oven batteries
IPC: C10B27/06
Filed: 1962-05-01
Abstract: <PICT:0939719/III/1> A coke oven battery comprises side-by-side coking chambers, a collector main 15 disposed along the length of the battery, an uptake pipe 13 leading from the top of each chamber into the main 15 (through a goose-neck 16), a pivoted valve 17 in each pipe 13 for controlling the gas flow therethrough, and means for actuating the valve 17, the means comprising an arm 21 for pivoting the valve 17, a continuously rotatable shaft 32, a disc 35 on the shaft and rotatable therewith, and a fluxible connection, e.g. a spring 26, between the disc 35 and the arm 21.  The valve 17 comprises a pan 18 which is filled with liquid from sprays 28, 31 when in its closed position E.  The apparatus operates as follows:-An electric motor 39 drives the shaft 32 uniformly to make one revolution per coking cycle, a disc 35 being provided for each chamber.  When a valve is in the open position A, an operator connects one end 37 of the appropriate spring 26 to a peripheral hole 36 in the disc 35 at position F.  For the first 200 degrees rotation of the shaft, the spring 26 exerts no downward pull on the arm 21. Thereafter, rotation of the disc 35 through a further 70 degrees pulls the lever 21, which has a counter weight 24 which balances the empty pan 18, down about a shaft 19 to raise the pan 18 successively through positions B...E.  The operator disconnects the spring 26 from the disc 35 to allow the disc to rotate unhindered through the last 90 degrees.  The valve 17 is opened manually for the cycle to be restarted.

Title: Improvements in or relating to the desulfurization of gaseous mixtures particularly synthesis gases
IPC: C10K1/32
Filed: 1950-07-06
Abstract: 672,500. Gas-purifying process. STANDARD OIL DEVELOPMENT CO. July 6, 1950 [March 23, 1950], No. 16946/50. Class 55 (ii). Sulphur compounds in water gas produced by gasifying solid carbonaceous materials with steam, are removed by bringing the gas into contact with a highly absorptive char of high surface area which has been withdrawn from the gasification zone. In the apparatus shown, finely-divided coal is fed from a hopper 1 into a first stage generator 5 and formed into a dense bed fluidized by a mixture of steam and oxygen admitted through lines 3 and 4. Water gas discharges through lines 10 and 11. The coke or char remains in generator 5 until its carbon content is between 45 and 75 per cent, when.its surface area is found to be a maximum, usually exceeding 500 square metres per gram. It is then withdrawn through lines 12 and 20 and is carried forward by the made water-gas from line 11, through a heat-exchanger 21, where the temperature of the suspension is lowered to between 75‹ and 400‹ F., to a desulphurizer 23, 1 to 2 per cent of air being added to the suspension through a line 22. A fluidized bed of the char is maintained in chamber 23, the organic sulphur compounds in the gas being adsorbed by the char and the H 2 S being oxidized by the air with the formation of free sulphur which deposits on the char. A cooling coil 34 maintains the bed at the correct temperature. Purified gas is led off through a line 24 and the sulphurized char through line 25, an air current from line 27 fluidizing the char in a regenerator vessel 28, so that the sulphur burns to SO 2  which discharges through line 29. The cleaned char leaves vessel 28 by line 30 and is taken up by a steam-oxygen mixture and fluidized in a second stage generator 16, the water-gas produced being added to that from generator 5, whilst ash is discharged through a line 19. If more char is produced in generator 5 than is required for desulphurization, it can be fed direct to generator 16 via line 14.

Abstract: 1276789 Television NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP 10 April 1970 [10 April 1969] 17086/70 Heading H4F In a television-telephone communication system comprising a plurality of televisiontelephone sets each comprising a television transmitter and receiver, and a transmitting means for providing a video/audio signal reproducable at a selected one of the sets, a light pen is provided at said one set for positioning against a desired point in the displayed image of the received video signal to produce signals indicating the position of the point, these signals being added to reference sync pulses separated from the received video signal to give a composite position indicating signal and the composite signal being transmitted to the transmitting means for reproduction or use thereof. In the arrangement of Fig. 1 the user of the television-telephone set interrogates and uses a computer 100 via the exchange 20 to book a seat in a train (seat diagram 32) or a seat at a theatre (seat diagram Fig. 7, not shown). To receive the seat plan &c. the user punches out the necessary code to the computer on pushbutton set 12. This is routed to the computer via the exchange and computer input terminal 90 and the computer replies at output 80 with video signals giving the display 31 of the seat plan and line/frame sync pulses which are separated out by means 62. In the display already booked seats are in black. To book a seat the light pen is removed from its cradle which causes switches 43 and 44 to move from the dotted positions (pen not in use) to the solid positions, and is pointed at the seat 34 to be booked. A photo-detector in the pen detects the scanning spot as it sweeps point 34 and produces a pulse (sharpened by pulse shaper 64) representing the position of point 34, which pulse is added at mixer 54 with the sync pulse from separated 62. The composite position signal fed to the computer causes it to resend the seat plan with seat 34 now black. With the pen back on its cradle, television camera 51 with its sync oscillator 50 can be used for video transmission to other sets. The computer may send voice information using a tape recorder and video information using a video tape recorder. The co-ordinates of seat 34 are determined by bistable circuits, set by the sync pulses and reset by the pen produced pulses, the bi-stable circuit output enabling a pulse counter such that the count therein indicates a co-ordinate. Instead of a computer, the user can communicate with a second user of a second televisiontelephone set (Fig. 5, not shown). A graph may be viewed by the second television camera and displayed at the first set and the light pen used to select a point on the graph which brightens up on the display at the second set and thence at the first set.
