Title: Improvements in or relating to blade adjusting means for controllable pitch propellers
IPC: B64C11/38
Filed: 1943-01-06
Abstract: 594,396. Variable - pitch propellers. UNITED AIRCRAFT CORPORATION. Jan. 6, 1943, No. 282. Convention date, Oct. 17, 1940. [Class 114] In a variable-pitch propeller the pitch of all the blades is changed simultaneously by an annular rotatable member having means for adjustably connecting it to each of a number of concentric arcuate sectional members connected to the blades so that the pitch angles of the blades can be adjusted with respect to each other. In the form shown, a gear element 22 on the root of each blade 12 meshes with one section of a gear 26 which is common to all the blades and has its sections slightly spaced apart. The gear 26 is rotatably supported in a bearing 28 which is retained against axial movement by a pair of annular pitch limit stops 34, 36 which are splined at 70 into the hub 10, a hub closure member 38 and a nut 40. The assembly also includes an annular member 44 with an enlarged portion 48 within the stops 34, 36, and a reduced portion 46 between the shaft 16 and a reduced portion 53 of the gear 26. The inner and outer surfaces of the portions 53, 46 are serrated to receive connecting elements 52, 54, 56 which are serrated on both sides in such a manner as to provide a vernier adjustment of each of them. The portion 48 of the member 44 has lugs 58, 60, 62, 64 which co-operate with lugs 66, 68 on the stops 34, 36 to positively limit the pitch-changing movements. The latter may be effected by means of a hydraulic vane motor, or by means of a cam operated by a single electric or hydraulic motor as described in Specifications 505,077, 505,168 and 505,169.

Patent GB-723548-A (GB)
Title: Improvements in or relating to method for converting oxygenated organic chemicals inhydrocarbon synthesis
Filed: 1952-01-08
Abstract: Carbonyl compounds and alcohols are converted to alcohols and carbonyl compounds respectively in a hydrocarbon synthesis reaction zone wherein synthesis gas composed chiefly of CO and H2 is partially converted to hydrocarbons by introducing into the reaction zone at a point above the level at which the synthesis gas is fed to the reaction zone, a carbonyl compound or an alcohol and contacting the latter in the zone with an active iron hydrocarbon synthesis catalyst substantially free from silica whereby the desired conversion is effected simultaneously with the formation of hydrocarbons. Oxygenated products obtained during hydrocarbon synthesis may be treated.  When carbonyls are converted it is preferable to inject them above the zone in which the principal conversion of CO to hydrocarbons occurs.  The compounds may be injected in the aqueous or anhydrous state. Conventional synthesis conditions are applied those preferred being H/CO mol. ratios of 1.5/1 to 2.0/1 at 600-700 DEG  F. and 325-425 p.s.i.g. with recycle ratios of about 1.2 to about 1.7 volumes of recycle gas per volume of fresh feed.  Mill scale is a preferred catalyst: catalysts of silica content not greater than 1 or 2 per cent are satisfactory.  The rate of introduction of the compound introduced to the reaction zone may be 20 weight per cent of the CO in the feed.  Liquid or vaporous carbonyls may be added.  In an example, propionaldehyde or 1-propanol obtained in a hydrocarbon synthesis from CO and H2 in the presence of a fluidized bed of mill scale catalyst is returned to the reaction zone and increased yields of 1-propanol or propionaldehyde respectively obtained. Specifications 682,833 and 684,968, [Group III], are referred to.

Title: Improvements in and relating to coin freed delivery apparatus
IPC: G07F17/42
Filed: 1919-01-09
Abstract: 141,135. Brooker, H. Jan. 9, 1919. Delivery of stamps from strips; coin action, thrust and multiple-coin; fraud, preventing.-The delivery mechanism of an apparatus suitable for vending postage stamps or tickets is wound up or set, step by step, by the insertion of successive coins which may be of more than one denomination, the last coin inserted actuating a release mechanism. The delivery mechanism, which may be of the type described in Specification 114,476, is actuated by a lever 9 controlled by a spring 37 and carrying a pivoted pawl 30 engaging teeth 29 on a lever 25 projecting into the coinshoot 4. The lower end of the lever 9 engages teeth 12 on a spring-controlled detent 110 carrying a coin-tray 12<A>. A coin of smaller denomination inserted in the shoot raises the lever 25 and thereby moves' the lever 9 through the space of one tooth 12, the coin passing to a pivoted tray 18 and dropping thence down a vertical part 5 of the shoot on to the tray 12A. The weight of the last requisite coin to be inserted depresses the detent 110 and releases the lever. A coin of a larger denomination will move the lever 9 through the space of two teeth, release taking place when the requisite value is inserted. According to the Provisional Specification, the pawl 30 may have a projecting wire for engagement with a tooth and released by the fall of a coin, which is adapted to prevent the engagement of the pawl with the next tooth on the lever 25 till the coin has fallen. Also, according to the Provisional Specification, the stamp to be delivered is cut off on the upward movement of the lever and retained on a delivery flap until discharge.

Abstract: PURPOSE:To detect the single operation of a generator in a fault on the side of a system inside a private installation. CONSTITUTION:In a system-linkage system, a private powergeneration installation is linked by a dedicated linkage line when a reverse power flow exists in a high-voltage distribution system. The system-linkage system is provided with reactive-power detection circuits 21, 22, 23 which detect the reactive power of a generator 2 and private loads 6, 7, with a reactive-power setter which sets reactive power supplied from a system bus 1, with a reactive-power control circuit 25 which uses the output of a reactive-power detector and the signal of the reactive-power setter as inputs and with a comparison circuit which controls the voltage of an AC generator and to which a control deviation signal for the reactive-power control circuit is input. Although normal-load reactive power is supplied from the generator and the system, the reactive power from the system in the power failure of the system becomes zero, the reactive power of the generator coincides with load reactive power, the deviation signal for control of the reactive power becomes large, and a breaker 5 which connects the system bus to a private system is cut off by detecting the signal.

IPC: G11B20/10
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To execute optimum equalization processing to a reproduction signal from each recording medium by controlling a group delay characteristic depending on a kind of the recording medium. SOLUTION: An input video signal is compressed by DCT and quantization or the like in a recording signal processing circuit 1 and the result is fed to a modulation circuit 2. The circuit 2 applies digital modulation processing to the compressed digital video signal to convert the signal into a signal with a form suitable for recording and the converted signal is fed to an amplifier 3. An output of the amplifier 3 is fed to a head 5 via a switch 4 and recorded on a tape 6. In the case of reproduction, original digital data are detected and converted into 1/0 signal and fed to a reproduction signal processing circuit 10. The circuit 10 applies nearly inverse processing to that at recording to obtain the original digital video signal.  An equalization circuit 8 of the reproduction system is provided with an amplitude correction section, a group delay correction section and a tape discrimination device and selects a group delay characteristic of plural all pass filters being components of the group delay correction section.

Abstract: PURPOSE:To keep air ratio proper by preventing the leak of air from dormant burners as much as possible during the startup period of a combustor by using a system in which combustion air is supplied independently to each of burners and air ports arranged in a plural stage. CONSTITUTION:In the actuation of a combustor having a system in which combustion air can be supplied independently through ducts 11-14, air is supplied from the air port and burners 4, 5, and 6 for two-stage combustion, and combustible gas is purged. Then, the burner 3 as a drive burner is ignited, and as the internal temperature of an oven rises, the supply of air is stopped in the order of the air port and burners 6, 5, and 4. Since the leak of air is negligible, the emission of NOx during the ignition of the drive burner can be greatly reduced.
