Title: Helicopter rotor
Inventor: FLINT JOHN AVERY
IPC: B64C27/18
Filed: 1964-10-20
Abstract: 1,073,418. Helicopter rotors. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Oct. 14, 1965 [Oct. 20, 1964], No. 42707/64. Headings B7G and B7W. [Also in Division F2] A helicopter rotor has blades on which circulation is induced by the discharge of fluid from spanwise extending slots, and has means for differentially varying the flow on separate spanwise sections of the blades. As described, each blade has three sections and air flows to them through an annular duct surrounding a duct (14) through which gas flows to a tip jet propulsion nozzle. The annular duct has three radial partitions (19a, 19b, 19c, Fig. 4, not shown) dividing it into three portions (20, 21, 22), which communicate with the three sections of the blade, and with vertically extending passages, radially separated by partitions (45, 46, Fig. 2, not shown), which communicate with stationary groups of concentrically arranged passages (51a, 51b, 51c) separated by concentric partitions (55) and radial partitions (50, Fig. 9, not shown). Thus, as the rotor rotates, the vertically extending passages on the blades sweep over the passages (51a, 51b, 51c), which contain butterfly valves (56) by which the flow may be adjusted, and the flow to the three sections of each blade may be varied differentially, to compensate for compressibility effects on the advancing blades and reverse flow on the retreating blade and to prevent stalling of the retreating blade. The valves (56) may be adjusted during flight, through rod, cable or synchronous motor, for example, automatically in accordance with flight conditions. The air supply passage (53) also contains valves (52) operated by a swashplate (63) for cyclic and collective control. The rotor may alternatively be driven by mechanical drive, and the blades may be circular or elliptical in section.

Title: Improvements in or relating to the mechanical cleaning of liquid fuels
IPC: B04B5/10
Filed: 1960-12-12
Abstract: 976,871. Fuel systems. T. RACZ. Dec. 12, 1960 [Dec. 12, 1959], No. 42762/60. Heading FIB. [Also in Division B2] In liquid fuel system, the quantity of fuel passing through a centrifugal separator is controlled by the fuel consumption. Fuel is pumped from a tank 1 through a restrictor 10, the pressure drop across which is inversely proportional to the level of fuel in a tank 2. The fuel passing through the restrictor is discharged through an elbow 11, falls down a conduit 30 to a heater 31, and passes through centrifuges 32, 33 before entering a tank 34 connected to the tank 2. Fuel from the tank 34 is pumped through a heater 41 to the distributer 43 leading to fuel pumps 45 on an engine 3, surplus fuel being returned to the tank 34. If more or less fuel than is necessary reaches the distributer, the level in the tanks 34, 2 rises or falls so that the pressure drop over the restrictor decreases or increases so that the quantity of fuel passing through the centrifuges is dependent on fuel consumption. Instead of the pressure drop across the restrictor being dependent on the level in the tanks 34, 2 only, it may also be dependent on the setting of the pump control.

Title: Improvements in detection of individual airborne particles
IPC: G01N15/06
Filed: 1966-09-27
Abstract: 1,107,683. Gas analysis. GENERAL ELECTRIC CO. Sept. 27, 1966 [Sept. 28, 1965], No.43029/66. Heading G1B. In a method of detecting bacteria in air the bacteria are pyrolyzed to form ammonia gas, the produced ammonia molecules being kept clustered together, and then converted to ammonium chloride by reaction with hydrogen chloride, water vapour being condensed on the clustered ammonium chloride molecules in a condensation nuclei detector 10 which also incorporates a scattered light measuring device 12 for detection of the produced condensation nuclei. The air stream under test enters an inlet 1 and strikes an impactor plate 3 which removes e.g. pollen particles. The air passes to a pyrolser 4 heated by a radiant heater 5 and including a portion 13 of converging diameter to provide a laminar air flow. Ammonia is produced from the protein in the bacteria and remains unmixed with the air in the laminar flow. The air then enters a chamber 7 wherein it reacts with a saturated hydrogen chloride and water vapour mixture from a source 8 under the action of a corona discharge between electrodes 9. Finally the air saturated with water vapour and containing the clustered ammonium chloride particles enters a chamber 11 in which it is mixed with ambient air at 100% relative humidity thus cooling the pyrolyzed air and causing condensation of water vapour on the solid ammonium chloride particles.

Title: Automatic Phase Correction of Digital Signals
Inventor: HAVEL JOHN FRANCIS
IPC: H04J3/06
Filed: 1968-09-24
Abstract: 1,192,892. Multipled pulse code signalling; automatic phase control. RAYTHEON CO. 24 Sept., 1968 [2 Oct., 1967], No. 45338/68. Headings H3A and H4L. An automatic phase correction circuit for interleaving digital data trains having the same bit rate, one train having an arbitrary phase relationship and the other train having a fixed phase relationship with a clock signal, comprises means for sampling said one data train with a narrow pulse at the bit rate as derived from the clock signal, means for storing the sampled data, control means for determining when the sampling pulse coincides with a data transition of said one train and for shifting the sampling pulse away from such a transition and means for interleaving the other data train and said one data train as recovered from the storing means. In an alternative arrangement both digital data trains have an arbitrary phase relationship with the clock signal and are each treated in the manner specified above before interleaving. Circuit details.-The data signal having an arbitrary phase relationship with the clock signal is designated DATA 2 and that having a fixed phase relationship is DATA 1. Bit rate signals D, a clock signal A comprising pulses at four times the bit rate, and data transitions X of the signal DATA 2 are supplied to a NAND gate 12. The output Y of gate 12 is applied to a bi-stable device 20 having feedback 22, 24 so that its condition is inverted on reception of a pulse Y, bi-stable 20 supplying an output 1 or 0 to NAND gates 28, 32 respectively. A signal B at twice the bit rate is supplied to NAND gate 28 and this signal inverted, B, is supplied to NAND gate 32. Gates 28, 32 supply an AND gate 38 whose output C = B or B (according to the state of bi-stable 20) is supplied to a NAND gate 42 and is also fed back to the gate 12. Pulses A and D and the signal DATA 2 are supplied to a gate 42 whose output G consisting of sampled data is supplied to a bi-stable 50 acting as a store. The bi-stable 50 is reset by bit rate pulses D and supplies a signal to a NAND gate 58 also controlled by pulses D. The other signal DATA 1 is fed in inverted form to a NAND gate 62 controlled by pulses D and the outputs of gates 58, 62 are combined in interleaved form at 68. Operation.-If the resultant narrow pulse E (A.C.D) sampling DATA 2 in gate 42 coincides with a data transition as represented by signal X, this is detected by NAND gate 12 which reverses the condition of bi-stable 20 to activate a different one of the NAND gates 28, 32 so that the output C= twice the bit rate square waves B or B, is inverted. This shifts the sampling point a quarter period of the bit rate away from the transition X of DATA 2.
