IPC: F02K1/74
Filed: 1959-01-28
Abstract: 879,969. Jet propulsion engine thrust reversing means. ROLLS-ROYCE Ltd. Jan. 4, 1960 [Jan. 28, 1959], No. 3137/59. Class 4. [Also in Group XXVI] A by-pass or ducted fan gas turbine engine has the by-pass or fan air passage divided into two ducts situated along the sides of the engine, and flaps interconnected with the engine thrust reverser and situated on the sides of the engine downstream of the open ends of.the ducts, so that when the thrust reverser is operative, the flaps move to positions in which they reverse the flow of by pass or fan air. In the Figure, air from the upstream stages 10a of a low pressure compressor 10 driven by a low pressure turbine 15 is divided between a by-pass passage 13 and the downstream stages 10b. A high pressure compressor 14 is driven by a high pressure turbine 11. The passage 13 is split into two ducts 19. The turbine exhaust gases thrust reverser 21, which may be as in Specification 745,649, comprises valve members 22 which in the reversal position divert the turbine exhaust to parts 24 in the fairing, normally fixed by flaps 23. During reversal, flaps 23 are moved to the broken line position, opening the ports and also reversing the by pass flow from ducts 19. The ducts may alternatively derive air from a ducted fan comprising blades at the periphery of turbine 15, or a third free turbine. If the ducts 19 are short, one pair of flaps 19 is used downstream of the ducts for reversal of the air flow and another pair of flaps is used to cover and uncover ports 24, see Fig. 10 (not shown).

Patent GB-1077335-A (GB)
Title: A device for measuring out doses of liquids by weight
IPC: G01F9/00
Filed: 1966-01-26
Abstract: 1,077,335. Automatic-feed weighers. H. LIST. Jan.26, 1966 [Feb. 2, 1965], No.3421/66. Heading G1W. In apparatus for metering successive doses by weight of fuel being supplied to an I. C. engine (or oil burner), the engine is supplied entirely from a measuring bowl 5 (through a pipe 14) attached to an arm 3 of a balance beam 1 whose other arm 4 carries a counterpoise 7 for the bowl 5 and, while a dose is being consumed, also carries a detachable counterpoise 8 corresponding to the predetermined weight of a dose, then when the engine has consumed the dose a fixed support detaches the counterpoise 8 breaking the electrical connection between its knife-edge and the earthed beam 1 so that feed voltage U B  is supplied to a motor 18 to drive a pump 17 to deliver fuel from a tank 19 to the bowl 5 and when the bowl 5 has received the full dose the beam 1 picks up the counterpoise 8 and the pump motor is switched off. An electronic control system includes three bi-stable switch steps 26, 27 and 28 connected to the weigh-beam-operated switches 9, 11 and 12 by leads 23, 24 and 25 connected through respective resistors with the feed voltage V B . The switch steps control the pump switch 34 and a gate 32 which when opened releases a pulse to a counter. A starter button 30 and a repeat switch 31 enable the system to operate in three ways. Normally with 30 and 31 open merely to check that the level of fuel in the bowl 5 alternates between two limiting conditions "empty" and "full". Secondly a measuring operation is started by pressing button 30, and this causes switch 34 to start the pump 17 and refill the bowl 5 irrespective of its condition. As soon as an overflow level is attained switches 11 and 12 make the circuit and when the overflow is absorbed switch 11 breaks the circuit and a gate pulse 33 is released to the counter. Normal operation follows without further gate pulses until another measuring process is initiated by actuating the button 30. Thirdly for the automatic repetition of the measuring process the switch 31 is permanently closed and with each emptying process a gate-pulse 33 is allowed to pass to the counter. The pump 17 may be replaced by a solenoid valve controlling the delivery of fuel to the bowl 5 from a container.

In a process for manufacturing combustible gas from liquid hydrocarbons by contacting them with a hot catalytic contact mass and in which plant-heating phases alternate with gasmaking phases, a lean-gas is produced in a gasproducing chamber 10 and is passed upwardly through a heat-storage mass 12 before passing downwardly through a gas-producing chamber 11 which is producing a rich-gas. The apparatus employed also comprises heat regenerators 13 and 14 and during a gas-making phase steam for the process is admitted at 21 and is preheated by downward passage through regenerator 13. Mixed gas from both chambers leaves at 24. During a heating-phase air for burning carbon deposited on the catalytic contact masses is admitted at 22 or 25. Chamber 10 which is operated at a higher temperature than chamber 11 has means 17 for supplying fuel and air for supplementary heating, the direction of gaseous flow being in this case from the rich-gas producing chamber to the lean-gas producing chamber. When the gaseous flow is in the opposite direction non-preheated air may be supplied to the gas-producing chamber 11 through a connection 26 in accordance with Specification 759,785. Similarly during a gasmaking phase the connection 26 may be used to introduce cooled or non-preheated gasification medium into the chamber 11. Heavy fuel oil is preferably used in the lean-gas chamber and gas oil in the rich-gas chamber. Specification 701,594 also is referred to.
