Title: Improvements in or relating to hydraulic governors for engines
IPC: B27K5/02
Filed: 1930-05-06
Abstract: 357,083. Engine governors. SIEMENSSCHUCKERTWERKE AKT. - GES., Siemensstadt, Berlin. May 6, 1930, No. 13923, Convention date, May 7, 1929. Addition to 314,809 and 336,517, [both in Class 57. Governors &c.]. [Classes 57 and 110 (iii).] A hydraulic governor for engines as described in the parent Specification in which a supplementary adjusting member is arranged and which, on fluctuations in the load on the engine, acting upon the stream of governing fluid in the sense of adapting it to the altered load, before the fluctuation of load has had its effect in a variation of speed. The Figure shows the invention applied to a turbine generator in which the hydraulic governor comprises a quantity member 5 and a pressure member B which maintains constant pressure behind the quantity member. The governing fluid from the pump passes through the opening c and divides into two paths, one, through the ports 1, 4 controlled by the valves 9, 10. And the other through the quantity member 5 which adjusts itself to allow sufficient area at f for the flow of fluid and simultaneously adjusts the throttle valve of the turbine 16. Arranged on the rod 11 connecting the valves 9, 10 is a solenoid 13 connected to a current transformer 14 in the output of the generator 15. Variations in the load causes the valves 9, 10 to be adjusted and varies the flow of fluid through the quantity member before the fluctuation in load has had its effect on the speed of the turbine. A dashpot arrangement 20 is mounted on an extension of the rod 11 in order that small fluctuations in load shall not affect the governor setting. A resistance 21 is also arranged in the solenoid circuit in order that the governor may be set by hand.

Abstract: 284,519. Hedgeman, L. C. May 25, 1927. No Patent granted (Sealing fee not paid). Road-traffic signals on vehicles.-A signalling hand, &c., A is mounted on a road vehicle so that it may be given independent movements in planes at right angles. The boss B of the hand is carried by a drum pivoted in a housing C, and movement in one plane is imparted by a pair of flexible wires D, E secured to the periphery of the drum. Movement in the other plane is imparted by a similar pair of wires secured to a drum T to which the casing C is attached by an arm S. Ball bearings are provided in a grease-containing casing, and spring-pressed locking balls Z are fitted. Fig. 6 shows the device for actuating the wires. A drum 0 to which the wires D, E, are secured is actuated by a lever R, and the casing N of this drum is carried by an arm U of a drum V to which the ends of the other pair of wires are attached.

Abstract: 1,159,303. Thermionic cathodes. SIEMENS A.G. 28 March, 1967 [29 March. 1966], No. 14008/67. Heading H1D. An electron beam generating system, e.g. for travelling wave tubes, comprises at one end of a hollow support 2 a porous emission substance carrier plate 1 which forms the main emissive surface and which is heated by the impact of the discharge from a secondary dispenser cathode 11, which is housed in the other end of the support 2 and which is raised to its operating temperature by a supplementary heater 5, which is subsequently switched off, the heat generated at the main carrier plate 1 being sufficient, when fed back to the secondary cathode via support 2, to maintain the secondary cathode at its operating temperature. As shown in Fig. 1, the supplementary heater may be an insulated coil of tungsten wire which is cemented to cylindrical portion 4 of support 2 by beryllium oxide, to improve the heat transfer. The supplementary heater may be automatically switched off at a preset temperature, e.g. by reference to its own resistance value,  and may be connected in parallel to the discharge section between porous plates 1 and 12. Alternatively, Fig. 2 (not shown), the supplementary heater may be an H.F. induction coil. In a further embodiment, Fig. 3 (not shown), the secondary cathode, comprising a cylindrical charge store closed at each end by a porous plate, may be housed enclosed within the main cathode which similarly comprises a porous plate closing each end of a hollow support. The auxiliary discharge from the other end of the main cathode may be used to activate a getter, e.g. Mo or C coated with Zr. The main cathode need not have its own store of emissive material but may instead be supplied by the secondary cathode. The porous emission substance carrier plates may be of carbon.

Abstract: 1535679 Radar SELENIAINDUSTRIE ELETTRONICHE ASSOCIATE SpA 5 April 1977 [16 Sept 1976] 14385/77 Heading H4D Radar R, Fig. 1, range and direction tracking a low height target B over a reflecting surface SR receives echoes via the reflected RR as well as the direct RD path. This causes an error in the tracking elevation of the radar which varies with range as shown at a, Fig. 2. It is found that the amplitude of the echo signal also varies with range as shown at b, the rapid variations being due to the radar being frequency agile. The slow varying component b' and the rapid variations are thus filtered out and the result signal c combined with the elevation error signal a to give a reduced elevation error signal d. The a.g.c. voltage for the I.F. circuit is used as the source of the amplitude.

Abstract: 199,572. Johnson, J. Y., (Wood, W.). May 23, 1922. Charging.-Relates to fuel-feeding apparatus of the rotary drum type, and comprises means for supplying liquid to the clearance space between the drum and its housing for preventing escape of gas through the feeding-apparatus. The apparatus shown consists of a rotary drum 6 mounted in a housing 3 carrying at one side a fiat-bottomed shoot 14 having an adjustable gate 18 for controlling the feed of fuel to the pockets 10 of the drum. The housing is fitted with an inspection opening 21, and the vanes 9 forming the pockets in the drum have Ranges 22, which hold back some of the fuel while the contents of the pocket are being discharged into the producer. A clearance of, say, one-sixteenth of an inch is allowed between the drum and the housing, and escape of gas is prevented by supplying water or other liquid through passages 12 to the space between the housing and the periphery of each end wall 8 of the drum, and through spraying nozzles 24, 26 into the pockets. The spray condenses on the machined surfaces of the housing and thus to a Jarge extent seals the clearance spaces. The peripheral portions of the end walls of the drum may be grooved. In a modification the drum consists of a cylindrical shell with a single compartment.

[Also in Divisions F2 and F4] A method of forming a lenticular tube 1 (see Division F2) comprises passing a tube 1a through successive pairs of peripherally grooved rolls 6, 7, 8, the sections in which the wall thickness is greater passing generally in the regions of the rolls where the grooves have their least depth. The tube la may according to a further method, be passed through pairs of grooved rolls and die surfaces which may be fixed or peripheral surfaces of rolls, the rolls and die surfaces being in the same plane (Fig. 9, not shown). The two longitudinal projections of the circular crosssection tube 1a co-operate with guides of the roll assembly. The tube may be heated locally at the portion of increasing wall thickness, this heating being effected by applying heat to only the required area or otherwise to the whole tube and subsequently cooling the appropriate sections. A lenticular tube of uniform wall thickness may be provided with a wall of varying thickness by passing a die through its bore. If the grooves of the rolls are deep distortion of the tube may occur. The distortion, however, may be eliminated by forming the grooves as the collective peripheries of a plurality of independently rotating discs.
