Title: Hot coke transfer system
IPC: C10B33/00
Filed: 1973-07-03
Abstract: 1437391 Hopper wagons; transporting special loads KOPPERS CO Inc 3 July 1973 [13 Aug 1972] 31718/73 Heading B7L [Also in Division F4] For handling hot coke from a coke oven there is provided a transfer car 11 having a refractory lined hopper 19 with an opening in its top for entry of the hot coke, a stainless steel wire mesh curtain 89 to close the opening when the hopper has been filled, and means for conducting gases away from the hopper interior and cleaning them; the gas cleaning apparatus being carried by a traction car 13 coupled to the transfer car at 15. The coke enters the hopper through an opening in a sloping surface at the top of a hood 29, Fig. 2. The curtain 89 is drawn over the opening from a reel 43. Gases extracted from the hopper interior pass through a duct 39, duct 127 provided with water spray nozzles (129) Fig. 6, (not shown), and then through venturi or wet scrubbers (128), cyclone separator 119, duct 139, exhaust fan 121 and stack 141. The stainless steel wire mesh curtain 89, Fig. 2, is carried by chains 67 at its sides which pass around toothed end plates 61, 63 of the reel 43 at one side of the hopper opening and around sprockets 69, 71 at the other side. The chains 67 carry the curtain 89 by being fastened to bars 91 which are secured to the curtain by U bolts (95), Fig. 4, (not shown) and bars (93). Regulation of the travel of the curtain is controlled by a mechanism (105) Figs, 2 and 5, (not shown). The bottom of the hopper has hinged pivotal gates 23, 25. On the traction car 13 there is an operator's cab 143. Electrified collector rails 35 and shoes 33 form part of an electrical interlock system between the coke guide hood at the coke oven and the hot coke transfer car 11.

Abstract: 814,027. Mixing fluids in flow. SHELL RESEARCH Ltd. July 23, 1957 [Oct. 18, 1956], No. 31753/56. Class 86 In apparatus for filling liquid gas containers, in which the gas is fed through a discharge line controlled by a valve, means are provided for substantially instantaneously injecting a predetermined quantity of a second liquid into the line, on opening the valve, this means being automatically recharged when the valve is again closed. In the form described a gas cylinder 1 is filled through a valve 7 and is supported on a weighing machine provided with a device such that, when the correct weight of gas has been admitted, a vane 26c is lowered between nozzles 26a, 26b to cause a back pressure in a chamber 32d and raise a diaphragm 32a. This closes a valve 32b and opens a valve 32c which allows gas from line 27 to reach a line 35 and actuate a pneumatic relay 33 which controls a metering pump to inject the correct quantity of additive into the supply line. When the cylinder has been removed a bleed valve 37 is actuated to exhaust the chamber 32d to cause valve 32b to open and 32c to close while line 35 is also exhausted, through a bleed line 36, so that the relay 33 returns to its original state, thereby causing recharging of the metering pump.

Title: Record card feeding and handling device
IPC: G06K13/14
Filed: 1957-10-11
Abstract: 855,815. Feeding sheets. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 11, 1957 [Oct. 12, 1956], No. 31842/57. Class 100(1) In apparatus for maintaining a card hopper replenished with cards, cards are fed from a magazine to the hopper by means under the control of an oscillating member which serves to align the cards in the hopper and is responsive to the height of the pile of cards in the hopper. The apparatus is described and shown for use with a high speed record card machine. the cards being separated from the bottom of a hopper 16 by a pusher separator 146 of the kind described in Specification 770.244, and fed by rollers 148 into the machine. A stack of cards 13 in a magazine 12 rests on rollers 112, 118 geared to a shaft 111 connected by a belt and pulley means to a shaft 80. When the shaft 80 is driven from a shaft 36, cards 13 are separated sequentially from the magazine 12 by the rollers 112, 118 and delivered into the hopper 16. The shaft 36 is constantly driven and a gear 82 which meshes with a gear 85 secured on the shaft 80, is rotatably mounted on the shaft 36 but can be clutched to the latter when detents on the clutch are released by latches under the control of a bell-crank lever 51 pivoted at 53. One end of the lever 51 has a roller 52 co-ooerating with a cam 39 on the rotating shaft 36, and the other end 54 is always in contact with a stop 130 on a frame 15 which is pivoted at 135 and urged towards the hopper 16 by springs 137. When there are sufficient cards in the hopper 16, the roller 50 is only engaged by the high part of the cam 39 whereby the frame 15 is constantly rocked away from the hopper by the lever 51, and returned by the springs 137: during these movements, pads 15c on the frame 15 abut the top cards in the hopper and align them. When, however, the height of the pile of cards in the hopper falls below the pads 15c, the stop 130 on the frame 15 can then move the lever 51 so that the roller 50 follows also the lower part of the cam 39, and the lever 51 can release the clutch latches to enable the shaft 80 to be driven. The feed rollers 112, 118 are now rotated to deposit cards into the hopper. A further cam-operated lever similar to the bellcrank 51 is disposed at the opposite side of the hopper. A cam-operated pad is also adapted to engage the side edge of the pile in the hopper 16, so that the pile is aligned along two adjacent sides.

Abstract: 640,534. Display cases. JANTSCH, H. Dec. 3, 1947, No. 31930. Convention date, Aug. 10, 1942. [Class 116] A sales display case consists of a baseboard in conjunction with a sliding frame by which goods on the base-board can be drawn forward, the sliding frame being operated manually. The base-board 1 fits into grooves 4 in the frame 2 and has battens 6 which fit over the shelf supporting the display case. The front board 5 of the frame serves as a handle by which the frame can be drawn forward and may carry a label or nameplate. The frame is drawn forward when the front row of goods has been sold and the back board 8 of the frame then pushes forward the goods on the base-board so that the second row of goods takes the place of the first row and the third row that of the second. The Specification as open to inspection under Sect. 91 comprises also filling the display cases by the use of U members in which goods are packed in the store room and which are then placed in the cases and suspending goods from straps fixed across the tops of the sliding frames. This subjectmatter does not appear in the Specification as accepted.

Abstract: 804,541. Light-sensitive mist detectors. GRAVINER MANUFACTURING CO. Ltd. Oct. 31, 1955 [Nov. 5, 1954], No. 32037/54. Class 40 (3). An arrangement for detecting excessive concentrations of oil mists in engine crank-cases (e.g. due to overheated bearings &c.) comprises a hollow louvred probe 10 adapted to be inserted into the crank-case and inside which is positioned a photo-electric cell 14 secured to and spaced a predetermined distance from (by means of hollow rods 20) a unitary structure including an electric lamp 13 the structure being arranged to be clamped between a flange 11, attached to the probe and secured to the outside of the crankcase, and a housing 12 the hinged portion 12a of which is secured, in the closed position by means of wing nuts 18. To prevent oil mist from entering the lamp housing 12 and the photo-electric cell housing 17 both housings are sealed by means of translucent windows 15 and 17b respectively. In an alternative construction the positions of the photo-electric cell and light source may be interchanged (Fig. 4, not shown) and in each arrangement supply leads to the element which is positioned inside the probe are brought out through one of the hollow rods 20 to a plug 31 to which the supply leads to the lamp are also connected and which connects with an external control and warning circuit arrangement via a plug and socket 31, 32. The latter circuit arrangement (Fig. 3, not shown) includes an indicating meter and a moving-coil relay, connected in series, and operated directly by the signal generated by the photo-electric cell. The meter is calibrated in terms of the obscuration of the photo-electric cell which is produced by the oil mist present in the probe (and therefore in the crank-case) and the relay is connected in a warning and indicating circuit arrangement which gives a visible indication of normal operation, with the concentration of oil mist at a safe level, and both a visible indication and audible warning when the oil mist concentration exceeds a predetermined level.
