IPC: H02K5/00
Filed: 1929-10-18
Abstract: 341,127. Dynamo-electric machines. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin.-(Assignees of Oesterreichische Siemens-Schuckertwerke ; 150, Engerthstrasse, Vienna.) Oct. 18, 1929, No. 31734. Convention date, Oct. 19, 1928. [Class 35.] Frames and supp o r t s .-A transportable dynamo electric machine is constructed as a rolling body in such a manner that the shaft bearings serve as the bearings of the rolling body. As shown; two angle-iron rings 1 are connected by straight angle-irons 2, 3 and bolts 4 with each other and a motor 5 is built into this frame. Below the motor, the fuse, switch and starter apparatus 6 is secured and a supply cable 13 is rolled around the bolts 4. For transportation purposes, a fork 7 provided with a handle 11 is secured to the motor shaft by blocks 8, 9. The pole has a support 10 by which the motor can be raised for uncoiling the cable 13. In addition, the member 7, 11 can serve as an anchoring means during operation of the machine and for this purpose it is detached from the shaft and secured to an auxiliary bolt 14. In order to reduce the diameter of the assembly, the starter or other apparatus 6 may be fitted outside one of the bearings in which case an arm or bridge thereon is provided with an eye or pin to engage with a corresponding pin or eye on the fork 7. The angle-iron 1 maybe dispensed with if the bearing brackets of the motor are constructed as runner discs.

Title: System for positioning a floating vessel
IPC: G05D1/02
Filed: 1962-08-20
Abstract: 994,996. Automatic position control. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Aug. 20,1962 [Aug. 22, 1961], No.31904/62. Heading G3R. The position of a vessel, e.g. for offshore drilling operations, is maintained constant relative to an anchor 14 by determining the error in angle between a tie line 13 and each of two planes XX and YY, and also the error in the vessels heading, and combining these vectorially in an electric circuit to produce correcting signals for controlling the magnitude and direction of thrust of independant stern and bow propellers 11, 12. The angles are measured by potentiometers operated by a gimbalmounted pendulum, their outputs being compared with a reference in separate controllers which position the sliders of further potentiometers in accordance either with the error, its differential or its integral (Fig. 2, not shown). It is stated that, if integral of error is used, correction for wind or waves is applied even when the actual error is zero. Two more potentiometers, gauged together, are controlled in accordance with the difference between the desired and actual heading, determined by gyrocompass, and yet another pair may be set manually to provide a bias. The arrangement is such that the heading error is both added to and subtracted from the vector sum of the two angular errors to produce two outputs, for stern and bow propellers respectively, which by their magnitude represent the correcting thrust required and by their phase angle (the relevent potentiometers being supplied with A.C. from various secondary windings on a common transformer) the direction of the thrust. The bias is added and subtracted in the same way as the heading error, but at 90 degrees thereto, and it prevents radical changes in the direction of thrust when the vessel is hunting over the desired position in calm conditions, the vector sum of the bias components being zero. The correcting signals control the propellers by closed loop servo systems, and provision is made for manual control. It is mentioned that there may be more than two propulsion units, and that synchronous induction devices may be used instead of the potentiometer circuits described. Specification 994,995 is referred to.

Title: Valve for liquid filling apparatus
IPC: B67C3/26
Filed: 1957-10-14
Abstract: 878,489. Bottling. HORIX MANUFACTURING CO. Oct. 14, 1957 [Oct. 15, 1956], No. 31994/57. Class 125(2). In a filling machine having a vertically reciprocable bottle rest and a filling head having a liquid tube the liquid outlet of which is at the lower end, upward movement of the bottle unlocks the filling tube which can then be lowered into the container. By altering the lowering means, filling may be whooly effected at the bottom of the bottle or the tube may be slowly raised during filling so that the liquid outlet keeps just under the surface of the liquid in the bottle. As shown, the invention is embodied in a rotating machine having a liquid tank 22 provided with valves 42 each comprising a fixed nozzle 43 in which is slidable a sleeve 44, 48 urged downwards by a spring 59 and carrying a bottle-engaging gasket 63. The lower end of the sleeve closes the liquid and vent openings of a combined liquid and vent tube 49, 57. This combined tube is supported by spring-loaded plungers 67 taking into slots 71 and by cam rollers 74 running on a cam 76 stationary within the rotating tank 22. By raising the bottle from the position shown, sleeve 44, 48 is lifted so that the liquid and vent openings are opened and filling takes place from the top until the liquid level occludes the vent opening. However by lowering the tank 22 relative to the bottle rests or by fitting thicker gaskets 63, the raising of sleeve 44, 48 will not only open the vent and liquid openings but will also, by means of the bevelled top 82 of the sleeve, retract plungers 67 so that combined tube 49, 57 is under control of cam 76 only. During further rotation, this cam lowers the tube 49, 57 quickly till its bottom is at the bottle bottom and then either maintains it there till the end of filling and raises it again or raises it gradually till the container is full to give under-surface filling, depending on the shape of the cam 76. When the bottle is removed, plungers 67 relock the combined tube in raised position.

Abstract: 968,713. Waveguide resonant elements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 10, 1962 [Sept. 11, 1961], No. 32527/61. Headings H1K and H1W. A variable reactive element for a waveguide comprises a wafer of semi-conductor material having on one side a conductive layer in ohmic contact with the material, the layer having at least one aperture affording reactive or resonant slots, the opposite face of the wafer being provided with carrier-injecting electrodes in the vicinity of the periphery of the aperture. The aperture 3 shown is of dumb-bell configuration and is formed in a conductive layer 2 which may consist of a metallic foil or a coating. An injecting contact 6 on the other side of the wafer runs around the periphery of the aperture and extends as far as the edge of the wafer. The effective size of the aperture depends upon the lifetimes and number of the carriers in the wafer. Hence, the resonant frequency may be varied by changing the potential across the electrodes. A different configuration may be used for the aperture; e.g. three parallel rectangular apertures may be used (Fig. 6, not shown).

Abstract: 1444281 Haymakers C VAN DER LELY NV 9 July 1973 13 July 19721 32639/73 Heading A1F A rotary rake head haymaker has tines Whose angles relative to radii of the rake head are continuously altered as the head rotates. A guide 93 mounted eccentrically of the rake head shaft 27 contains rollers 92 which are attached to the tines 46 through rods 80 and links 70 pivoted on a pulley 43. The rods are slidably supported on the hub 41 by bearers 86. The guide 93 can be adjusted relative to the shaft 27 both linearly and rotationally. A slot 103 in the guide (see Fig. 5) allows relative movement between the guide and a plate 98 secured to shaft 27 upon rotation of crank 110. The plate 98 slides between strips 97 rigidly secured to the guide and thus controls the angle through which the tines are moved as the head rotates. In order to alter the position, relative to the direction of travel, at which the tines are extended crank 106 moves pin 102, which is secured to the guide, around slot 101 in plate 100 rigidly fixed to the rake head shaft 27. The rake head is supported by a wheel 115 which can be adjusted about a horizontal and a vertical axis or iby an annular or dish-shaped supporting member fixed to shaft 27 or freely rotatable relative thereto, (see copending Specification 1444282). The rake heads shown in Figure 1 are rotated in opposite directions by means of a gear box 15 mounted on coupling frame 6. A drive connection 22 for shaft 40 enables the heads to be rotated in the same direction. The distance apart of the rake heads is adjustable by crank 35 (Figure 1) moving telescopic frame parts 29, 32. The tines are secured to link 70 by shaft 60 (Figure 4) supporting a plate 53 to which the tine holding plate 52 is secured by wing nut 56. The plate 52 can be inverted when the rotation of the rake head is reversed and enables the tines to project through windows 69 in a cylindrical plate 68. In embodiments the guide 93 is replaced by a ring, conical or like member pivotable about an axis perpendicular to the rake head shaft 27, the ring also being movable axially of the shaft (see copending Specilfication No. 1444283). In a further embodiment the tines are curved so that in their inoperative postions they lie along the surface of cylinder 68. By adjustment of the tines two rake heads can be made to ted or to form different thicknesses of swath. By rotating both heads in the same directions side delivery or swath turning is accomplished.

Filed: 1973-07-10
Abstract: 1440226 Centrifugal pumps L A HUETTNER 10 July 1973 32750/73 Heading F1C [ Also in Division F4] In a liquid heating device a ring of the liquid (e.g. water) is maintained by centrifugal action on the inside of a drum 10 which is rotated by a pulley 26 and is heated directly by flames discharging from a burner 34 against the inner surface 60 of the liquid ring. Liquid is admitted to the ring through the periphery of an inlet stator 56 and is discharged from the ring through the periphery of a discharge stator 58 the peripheries of both stators being immersed in the liquid ring and liquid flow via the ring being produced by having the periphery of the discharge stator 58 closer to the drum wall than that of the inlet stator 56. Each stator comprises a pair of spaced-apart circular plates with curved vanes extending between them. In use, cold liquid is admitted at an inlet 40 leading to the stator 56 and heated liquid discharged from the stator 58 passes via tubes 62 and a chamber 64 to an outlet 66. The flow of heated liquid may be controlled by a valve (not shown) at said outlet the relative pressure changes in the apparatus caused by the operation of this valve producing corresponding changes in the rate of inlet water flow at 40. The drum 10 is provided internally with longitudinal baffles 12 and tranverse perforated baffles 14, these effecting mixing of the hotter and cooler layers in the liquid ring. When the apparatus is shut down, liquid collects in the space 54 as the liquid ring collapses. On restarting, most of this liquid is sucked back into the drum 10 by the action of ridges 50 on a rotating conical pump member 44 extending downwardly from the drum 10 and having slots 46 therein. Vanes 48 on this member act to discharge the burner combustion gas via chambers 54 and 74 to a flue 76.
