Title: A machine for removing and replacing lids of charging openings into coking plants
Inventor: NEPOMNIASHTSHY IGOR LAZAREVICH
IPC: C10B25/20
Filed: 1961-07-17
Abstract: A machine for removing and replacing the lids 19b of the charging openings in vertical coke ovens and for clearing charge from around and into the openings, comprises a scraper mechanism 7, lid-gripping mechanism 6, means including a vertically movable hollow bar 18 for swinging the mechanism 6 into and from a position over a charging opening, the bar 18 being attached to transmission gearing 5, means including a pin 41 on the bar 18 and a slot 42 for rotating the bar 18 during vertical <PICT:0999673/C4-C5/1> movement thereof, and blowing nozzles 28 for clearing the charge. An electric motor rotates a horizontal shaft 31 and a vertical shaft 14 through worm gearing 10, rotary motion of the shaft 14 being transmitted via a shaft 16 and splined connection 17 to the gearing 5 which continuously rotates the mechanism 6.  Rotation of the shaft 31 causes vertical reciprocatory motion of the bar 18 through linkage 33 . . . 39, and thus of the parts 5 . . . 7, a slot 34 permitting a dwell at the bottom of the stroke.  A clutch 43 on the bar 18 engages a clutch 44 resiliently mounted on the shaft 16 when the bar 18 is at the top position, rotary motion being thus transmitted momentarily to the bar 18 to cause the pin 41 to move into the appropriate branch 421, 4211 of the slot 42 as the bar 18 begins to descend, to cause a swinging through 60 degrees of the parts 6, 7 with the part 5 as radius. The machine appears to operate as follows: The parts 6, 7 are swung and simultaneously lowered, the mechanism 6 being rotated as explained above, till lowering is arrested by a buffer 30 engaging a lever 38 during the dwell, the mechanism 6 being aligned with a lid 19b which it grips bayonet-joint fashion and rotates to loosen.  Further rotation of shaft 31 raises the parts 18, 5, 6, 7 to lift the lid and swing it away from the charging hole. The motor is switched off until the oven is charged, and switched on in reverse direction to lower the bar 18 and swing the parts 6, 7 in the other direction so that the mechanism 7 clears charge into the hole with scrapers 27 and nozzles 28, the mechanism 7 being automatically energized by a lever 46 contacting an abutment, until the parts 18, 5, 6, 7 are raised. Finally, the motor is energized in its original direction to lower and replace the lid, and is automatically reversed to release the lid when it has been positioned.

[Also in Division H2] In television or other equipment using valves and transistors, the valve filaments and/or heaters are used as part of the smoothing filter for the transistors. In Fig. 3, the A.C. mains voltage is rectified at 3 to provide a D.C. voltage across capacitor 4 for use as H.T. supply to valve circuits 5. This voltage is reduced and smoothed by valve heaters 6, resistor 17 and capacitors 18, 23, 7 before being used as supply voltage in the audio amplifier comprising transistors 20, 19, 8 and in other transistor circuits 9. Resistor 24 is adjusted so that the D.C. voltage developed across the load 10 is equal to half the voltage across capacitor 7. The nipple across capacitor 21 is amplified and inserted by the first audio amplifier 20 so that it neutralizes the nipple fed in from capacitor 7. A fusible resistor 2 and a surge-suppressing capacitor 29 are connected to the mains input terminals 1. Modifications.-In Fig. 2 (not shown) a separate rectifier provides a negative supply which is smoothed by valve heaters and two capacitors before being fed to the audio output transistor. The negative supply for other transistor circuits is obtained by smoothing the D.C. voltage developed across the loudspeaker. In Fig. 4 (not shown) the valve heaters are fed with unsmoothed half cycles of alternating current.

Patent GB-262421-A (GB)
Abstract: 262,421. Siemens & Halske Akt.-Ges. Dec. 2, 1925, [Convention date]. Factory and like time-recorders, card-type; impression mechanism. - In a workmen's timerecorder wherein the times of arrival and depar. ture are printed on different parts of the card, the portion cut out from the edge of the card is removed in two lateral steps, this stepping controlling the lateral shifting of the platen mechanism or of the type wheels. The card 1 is inserted between platen levers 10, 11 and clockwork-driven time type-wheels 6, 7, 8, of which 6 is the day wheel, 7 the hour wheels for arrival and 8 the hour wheels for departure. When an operating-handle shaft 28 is rotated a hammer 13 moves a frame 14 so that one of two lugs 15, 16 thereon co-acts with its platen lever 10, 11 according to the lateral position of this frame, which co-operates with the head 17 of a frame 32 controlled through a lever 24 by a cam 27 rigid with the shaft 28. This head 17 also carries the knife 18 which has a lug 21 adapted to co-act with the lateral edge of the card. On arrival the card is inserted until arrested by a fixed stop 4 and the lug 21 contacts with the card as at E, Fig. 5 and in this position the lug 15 co-acts with its platen lever 10 to print the arrival time when the knife 18 cuts out the first portion of the card. On departure the card is held at the same position by the pin 4 but the lug 21 moves further in as at A, Fig. 5. Thus the head 17 moves to the left and displaces the frame 14 so that the lug 16 effects printing from the type wheels 8 on a different part of the card while the knife cuts the second portion, laterally, out of the card. The knife-anvil 20 is struck bv a second hammer simultaneously with the action of the platen-hammer 13. On the next arrival the card moves further into the apparatus before reaching the stop pin 4. Instead of printing the time, it may be recorded by punched holes.

Abstract: 1,077,912. V.T.O.L. aircraft. GENERAL ELECTRIC CO. June 23, 1965 [June 25, 1964], No. 26573/65. Heading B7G. [Also in Division F1] A control fan for a V.T.O.L. aircraft is provided in a wing 10 and comprises a rotor disc 13 carrying fan blades 16 and turbine blades 20. Compressed air or hot exhaust gas is supplied to a scroll 21 and is directed by a nozzle structure 22 on to the blades 20 to rotate the rotor disc. Guide vanes 18, 19 are pivotable from a position in which the air flows downwardly through the fan to a position in which the air flows upwardly. The fan rotor blades 16 are of impulse, i.e. symmetrical, form so that they are equally suited to both directions of flow. The guide vanes 18, 19 may be pivoted in unison so that air flow through the fan is uniform over its circumference. Alternatively, they may be controllable in groups of two or more vanes whereby the reversal of direction of flow does not occur simultaneously over the whole circumference of the fan but instead occurs progressively and sequentially over separate sectors. In the neutral condition in which there is no net upward or downward thrust exerted by the fan, there is then an upward flow over half the fan circumference and a downward flow over the other half. The fan therefore consumes the same power under all conditions and does not tend to overspeed in the neutral condition. The means 26 for pivoting each guide vane may comprise a vane (29), Fig. 4 (not shown), which can be moved from one position to the other by supplying air through ports such as (28) under the control of a valve (27). The individual valves (27) can be connected by a link 30 so as to operate either in unison or sequentially in groups.
