Title: Improvements in or relating to Rotary Engines
Inventor: ANDREW THOMAS WILLIAM
IPC: F01C1/00
Filed: 1966-01-14
Abstract: 1,156,441. Turbines; gas turbine plant. T. W. ANDREW and J. D. YANDLE. Sept. 14, 1966 [Jan. 14, 1966], No.1975/66. Headings F1G and F1T. A gas turbine engine including a rotor disc having peripheral depressions to receive power impulses from combustion gases has a circumferentially extending resilient sealing ring mounted on the rotor disc to provide a seal between the disc and the surrounding stator housing, the ends of the ring engaging in a further depression in the disc so as to limit circumferential movement of the ring. The rotor disc 27 is splined on a shaft 10 and contained in a horizontally split housing 16 having upper and lower parts 16a, 16b. The disc 27 has a series of peripheral depressions 37a to 37e inter-connected by passages 39a and an exhaust port 38 connected to depression 37a by a passage 39b. A resilient sealing ring 30 having apertures in registration with the depressions 37, port 38 and a closed depression 40 is mounted on the periphery of the disc 27 by engagement of turned-in edges 31 of the ring 30 in annular grooves 32, circumferential movement of the ring being prevented by engagement of the ends 34 of the ring in a further depression 33. The shaft 10 also carries a centrifugal compressor 54 which draws in air through an inlet 56 and feeds it to an annular chamber 58, the latter communicating with a passage 52 in a plate 22. A rotary valve disc 48 mounted on shaft 10 adjacent plate 22 has ports 49, 51 to control the flow of combustion and scavenging air from passage 52 to passages 41, 42 leading to a combustion chamber (59, Fig.2, not shown). Petrol is injected into the combustion chamber and ignited at the instant that depression 40 in the disc 27 is in communication with the outlet port 61 of the chamber so as to give the disc a driving pulse. When depression 37e passes under the port 61, port 51 in valve disc 48 permits scavenging air to flow to the combustion chamber and thence through port 61, depression 37e and passages 39a, 39b to the exhaust port 38 of the disc 27, the latter port communicating with an exhaust outlet 43 in housing 16. Cooling of the engine is effected by an air blast produced by a fan 29a at the end of shaft 10, the air passing over fins on the combustion chamber (59) and also through hollow bolts 29 holding the assembly of stator parts together. The sealing ring 30 is lubricated by oil supplied though a passage 35 in the housing 16 to the depression 33, the oil returning to a pump throughapassage36. In modifications, the compressor 54 may be driven from shaft 10 through step-up gearing, and braking may be effected when the fuel supply is cut-off by directing a reverse air jet onto a suitable depression in the rotor disc periphery via a control valve. Several rotor dics may be mounted on a single shaft.

Title: Improvements in lid supporting means for cabinets or boxes
IPC: E05C17/08
Filed: 1928-01-23
Abstract: 311,837. Stone, J. A. Jan. 23, 1928. Stays.-The hinged lids of cabinets and boxes are held in an open position by a stay 1 which embodies a pivotally-mounted guide member 25 and an arm 21 with a pin 20 adapted to engage a recess 17 in a block 9 secured to the stay-arm when the lid has been lifted into the open position and then slightly lowered, as shown, the arrangement being such that to close the lid it is first lifted until the pin contacts with the incline 34 of a block 10 and then lowered, the pin 20 then travelling through the passage 12 until it travels up the incline 19 of the block 8. With the pin 20 in this position, it engages with the incline 18 of the block 9 when the lid is being opened from the closed position, and by travelling along the passageway 11 it comes into contact with the incline 15 and rests in a recess 33; by then lowering the lid a little it is guided by the straight edge 16 of the block 10 into the recess 17, the cycle of operations being then completed. The guide block 25 is mounted on a pin 22 which is attached to the box 7 and engages with the slot 27 in the stay-bar 1, the guide block sliding between flanges 2 as the lid is being moved. A friction washer 28 is mounted between the members 21, 25. In a modification the guide blocks for the pin 20 are arranged at the lower end of the stay-bar, which slides in a box-guide positioned near the upper part of the stay-bar when the lid is closed. The stay-bar may also be pivotally attached to the box and the guide member secured to the lid.

Title: Improvements in or relating to the production of liquid hydrocarbons by the thermal treatment of carbonaceous materials
IPC: C10G1/00
Filed: 1934-01-22
Abstract: In the production of valuable hydrocarbons by the heat treatment of solid carbonaceous materials, the basic constituents of the materials are neutralized wholly or in part prior to the heat treatment and then subsequently at any stage during the treatment substances having an acid reaction under the reaction conditions are added.  The heat treatment includes such processes as destructive hydrogenation, low temperature carbonization, coking, &c.  The initial materials, e.g. bituminous coal, brown coal, peat, &c., are neutralized by treatment in a finely divided state with inorganic or organic acids, the acids being preferably sprayed onto the carbonaceous material soaked with catalysts. Surface-tension reducing agents may be added.  The acids may also be added to carriers, e.g. activated coke, carbon, silica, &c., which have been previously treated with steam or hydrogen at 300--900 DEG  C.  The acid reacting substances added during the reaction include organic halogen compounds which yield halogen halide under the reaction conditions, e.g. carbon tetrachloride, chloroform, methylene chloride, and halides of arsenic, phosphorus, antimony, ammonium chloride &c.  Chlorine, sulphur dioxide, hydrogen chloride, &c. may be injected into the reaction chamber.  Finely ground bituminous coal containing 12 per cent ash is treated with dilute sulphuric acid containing 0,1 per cent di-isopropylnaphthalenesulphonic acid and 0,03 per cent ammonium molybdate and then dried and made into a paste with an equal amount of heavy oil, 0,75 per cent chloride in the form of carbon tetrachloride is added to the mixture which is passed through a preheater heated to 450 DEG  C. 97 per cent of the carbon content of the coal is converted.  Specifications 406,006, 407,034, 407,992, 408,004, and 408,255 are referred to.

Title: Improved variable pitch propeller
IPC: B64C11/40
Filed: 1956-01-24
Abstract: 779,116. Variable pitch propellers. GENERAL MOTORS CORPORATION. Jan. 24, 1956 [Feb. 3, 1955], No. 2276/56. Class 114. In a variable pitch propeller, hydraulically actuated, a heat exchange reservoir attached to and rotatable with the propeller is subjected to a flow of air over its exterior periphery during rotation of the propeller, and liquid from the actuating system is conducted to the reservoir to be cooled thereby, cooled liquid being conducted back to the system. A hub 20, Fig. 2, splined to the engine shaft 24 mounts blades 22 rotatable axially in ball bearings 23 when a piston 51 and cylinder 45 are axially displaced relatively to one another, the piston and cylinder and a stationary sleeve within the piston being connected by helical splines. The liquid is pumped from a chamber 79 formed by a stationary sleeve 78 coaxial with the shaft 24, and a cover. 77 secured to a back plate 76 disposed behind the blade sockets. Oil from this chamber, heated by operation of the control system is delivered to a chamber 180 at the front of the hub 20 entering between the wall of the chamber and an annular baffle 213 which directs it along the wall. The chamber 180 and a shroud 183 constitute a heat exchanger 30, fins 182 on the chamber 180 providing a pump by which air drawn in through the apertured nose 40 of the front section 36 of the propeller spinner and a tube 41 associated therewith is guided over the surface of the chamber 180 to cool it. The spinner comprises front, middle and rear sections 36, 34, 32, the blades projecting through apertures between the sections 34, 32. Bulkheads 43, 35 and 33 support the sections. The chamber 180 houses a feathering motor 220 adapted to drive a gear pump 235 supplied from a reservoir 219 in a back plate 197 to which the motor and the casing 180 are bolted. Electrically the motor is connected through terminals 227, 228, 229 and straps 230 to slip rings 171 mounted on the cover 77 and on energization drives the pump to deliver oil at about 400 lbs. pressure to feather the blades. The remainder of the system operates at a minimum pressure of 20 lbs. per square inch, this being the pressure required to operate a restrictor valve 95, Fig. 8, mounted on the back plate 76 which carries gear pumps 87, 88, 89, for supplying the pressure liquid, and the control valve assemblies and has cast in it liquid passageways for serving them. If the speed of rotation of the propeller is too low to actuate the gear pumps 87, 88 and 89 effectively, the feathering pump may be used to rotate the blades. Specifications 713,280 [Group XXXV] and 724,855 are referred to.

Title: Method and system for measuring doppler frequency shift of an echo
IPC: B60R21/00
Filed: 1975-01-20
Abstract: 1482816 Radar MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 20 Jan 1975 [18 Jan 1974] 2310/75 Heading H4D A radar system for measuring the Doppler shift of frequency of an echo due to relative movement of a target and a point of reception of the echo comprises transmitting a diverging beam of electromagnetic radiation in a direction such that the moving target traverses the beam, receiving reflected signal from the target, and developing an oscillatory Doppler signal which varies as a function of the Doppler component of the received signal which varies in frequency as the target traverses the beam, counting, after initial deflection a predetermined number of cycles of the Doppler signal, and then measuring the maximum frequency of the Doppler signal thereafter which frequency is representative of the velocity of the moving object. When a target 1 enters the detectable range of beam 5, an echo is produced with a Doppler frequency proportional to the relative velocity radial component. The Doppler signal is detected at 11 conventionally, and passed through Schmidt trigger 13 where it is converted to a train of positive going pulses (Fig. 4b, not shown) which are counted separately by counters 15 and 16. Measurement of the Doppler frequency takes place during the period between the end of the pulse count in counter 15 and the end of the pulse count in counter 16, over a fixed number of Doppler frequency cycles, confined to a selected narrow region of echo. An enable signal corresponding to this period appears at the output of AND gate 23, which opens gate 25, allowing passage of a signal from unit 24, which converts the value of the detected Doppler frequency into a variable voltage, to the input of peak detect and hold unit 26, which stores the peak value of Doppler frequency in the selected region until reset by signal f from reset circuit 10. The signal from the peak detector 26 is displayed at 18. When the end of the Doppler echo signal at the output of Schmidt trigger 13 is detected by reset circuit 10, (corresponding to the exit of the target 1 from beam 5), monostable 31 produces a reset signal f, which clears counters 15 and 16 and resets hold circuit 26. In a modification to the measuring circuit (Fig. 3, not shown) an AND gate (32) is connected to Schmidt trigger circuit 13 and AND gate 23 to pass the output from 13 to a pulse interval detection circuit (33) which converts the detected Doppler signal to a digital quantity the minimum period of which is detected by a minimum value detecting and hold circuit (34), which value is cleared by a signal from reset circuit 17. A converter (35) inverts the above minimum value to yield a signal proportional to the Doppler signal frequency.
