Title: Improvements in or relating to the Carbonisation of Fuel by Vertical Coke-ovens and the like.
Inventor: DAVIES WILLIAM EVERARD
IPC: C10B5/10
Filed: 1918-12-19
Abstract: 136,880. Davies, W. E. Dec. 19, 1918 Coke ovens etc.; discharging; casings.-Consists mainly of improvements in the heating walls of coke-ovens and the like for carbonizing or distilling solid materials such as coal, shale, peat, wood, lignite, cannel, or refuse, and either intermittent or continuous in action. The heating wall, shown in horizontal section in Fig. 1, comprises alternate combustion flues 1 and waste heat flues 2, behind which is a second set of waste heat flues 3, the arrangement being such that hot gases from the top of each combustion flue 1 are divided between two waste heat flues 2, 3 in proportions determined by a valve (adjustable through a poke-hole) between the top ends of the flues 2, 3 and by the draught in the respective flues. The reverse direction of flow may be adopted with suitable alterations of the supply and exhaust connexions. The flues 1, 2 are of triangular, oval, or heart section, and the flues 3 rectangular and either open or filled with chequer work. A burner 21 is placed at the bottom of each flue 1, Fig. 3. Air from a branch pipe 17 and gas from a branch pipe 18 are mixed by a revolving mixer 19, and the mixer passes into the oven main 4<11> and thence to the burner pipe 16, secondary air entering through a hit-and-miss valve 4<1>. A valve 20 prevents backfiring. To direct the heat towards the inner wall of the flue the burner may be perforated only towards that side, and the flue may contain similarly perforated diaphragms 22, either cup-shaped, as shown, or flat. Gases on leaving the flues 3 enter a flue 25, Fig. 4, extending around one half of the oven, and traverse a similar flue 26 beneath it in the opposite direction before reaching the chimney. As shown at the right-hand side of Fig. 4, the heating wall may be built in stages or stories each having its own burners and exhaust flues 25, 26, the vertical flues of successive stages being in staggered relation. To prevent leakage when the oven is worked under vacuum or pressure, metal sheets 25<a>, 1<a>, Fig. 9a, are built in between the stages and between the two parts of the double inner wall. The heating wall is surrounded by an asbestos or like jacket 6 and a water jacket 7. The oven is charged at the top and discharged through a door 32, Fig. 4, carried by arms 35 and operated by a rack 33, which may be actuated by a modified coke oven pusher. For continuous discharge, like adaptations of known discharge means may be utilized in multiple along the length of the retort. Specifications 5464/90, 22274/07, 3197/10, 7049/10, 111,871, and 127,940 are referred to.

[Classes 39 (i) and 40 (iii)] A device for producing radiation of infra-red or longer wave length, which may be used for signalling, comprises an evacuated chamber containing a layer of material capable of producing such radiation when excited by electron or ionic bombardment, by X-rays or by a glow discharge, such as a selenide or telluride of zinc, cadmium, or mercury or a mixture of these substances, and exciting means of such nature within the chamber. A mercury telluride produces radiation up to several thousands of a millimetre in wave length. Activating metals such as copper, silver, platinum or yttrium are added to influence the sensitivity of the substances and the wave length produced. The layers of the infra red luminescent substance may be mounted on the inner wall of an evacuated glass or quartz envelope G. An accelerating electrode B, a control grid if desired, and an indirectly heated cathode K are mounted inside the envelope. Instead of the grid B, metallic particles may be embedded in the layer S and connected to a source of positive voltage. Applications to glow discharge tubes and envelopes made mainly of metal are also described. Further, electrons emerging from a, cathode can be used first for producing X-rays and these then employed for exciting the layer. The device may be used as a transmitter for telegraphy or telephony on infra-red waves by fitting it with radiation control means, e.g., by controlling its energization, and placing it at the focus of a parabolic reflector. At the receiving end the radiation may be picked up by a bolometer or ultra short wave demodulator also placed in a reflector.

Title: Power drive systems for gas turbine engines
IPC: F16H47/04
Filed: 1974-05-16
Abstract: 1426979 Variable-speed gear GENERAL MOTORS CORP 16 May 1974 [20 July 1973] 21774/74 Heading F2D A variable-speed hydromechanical drive system for a vehicle powered by a gas turbine engine of the kind having a free turbine constituting the output means, which delivers maximum torque when stalled, comprises a hydrostatic transmission of which at least the pump 26 is of variable displacement, first continuous drive means 28, 20 between the turbine 14 and the pump, a planetary gear set comprising a sun gear 46 connected by second continuous drive means 34 with the motor 30, a ring gear 48 connected to the output shaft 54, and planets 50 meshing with the sun and ring gears and mounted on a carrier 42 which is connectible by selectively engageable clutches 22, 36 with the first and second continuous drive means. The arrangement allows use of hydrostatic units with relatively low torque handling capacity by enabling power to be transmitted solely mechanically at low speeds, when torque is highest. As shown, both pump and motor are of variable capacity, having servo adjusting means 28, 32, and the carrier 42 may be held by a brake 40 for reversing. When starting, both pump and motor are set to the same displacement, the brake 40 is released, and clutches 22, 36 are engaged, so that drive is transmitted from the turbine, which may start from a stalled condition, direct to the output shaft 54, the planetary train being locked by the clutch 36, and the pump and motor rotating idly in unison. When the turbine reaches its maximum speed the clutch 36 may be disengaged whereupon the planets will attempt to drive the sun and motor at increased speed so that the pump acts as reaction means. The pump displacement may now be reduced to slow down the motor and sun so that output speed is increased. Further increase of output speed is obtained by adjusting the pump displacement through zero to maximum displacement in the opposite sense, followed by reduction of the motor displacement. For reverse drive the pump is set initially at zero displacement, clutches 32, 36 are disengaged, and the brake 40 is applied. The motor and sun will then drive the ring gear through the non- orbiting planets as the pump displacement is increased. As operation in this mode is limited by the torque handling capacity of the pump and motor means may be provided for limiting the hydraulic system pressure. Various alternative modes of operating the drive system are described. To enable full torque to be transmitted in reverse a modification is described having a reversing gear between the turbine and the clutch 22.
