Title: Improvements in motion transforming mechanism
IPC: F16H27/02
Filed: 1929-11-06
Abstract: 334,778. Florisson, C. L., and Soc. de Condensation et d'Applications MÚcaniques. Nov. 8, 1928, [Convention date]. Echo distance-measuring apparatus.-A device for converting continuous rotary into reciprocating or oscillating motion, applicable to echo sounding- apparatus &c. comprises a driving wheel A, which may be of cam form, having a number of ratchet teeth C, or indentations disposed equidistantly or otherwise, such teeth engaging intermittently with a bar M carried on a flexible strip or wire E, F stretched between springs G, H, spring G being sufficient to overcome spring II plus the frictional resistance of the wire. As shown in Fig. 1, the wire carries a body N to be reciprocated, and in Fig. 3, movement of the wire is used to oscillate a shaft carrying a wheel Q which may be of cam form, as also may be wheel A. In operation, the bar M is moved to the right by a ratchet tooth until either it reaches the end of the driving are or is freed by a fork P, whereupon it is rapidly returned by spring G. Return movement may be limited by a stop so arranged that in the absence of a tooth from the driving arc, the bar M lies near the point K. The ratchet wheel is grooved to receive the wire, movement of which may be guided or deviated by grooves in fixed members or rollers. The wire and bar M may be replaced by a flat strip having a tooth-engaging hole, and a number of members may be reciprocated or oscillated from a single shaft. The ratchet wheel may be driven at a speed which varies according to a predetermined law. As applied to apparatus for sounding by echo, the member N sets free the acoustic signal by passing over an electric contact, detects it either visually or graphically and later the echo from the sea bed. The body N moves at a constant speed in front of a scale upon which the time interval between the release of the signal and its echo is measured from which the depth of the sea is calculated.

Title: Improvements in or relating to steadying device for rolling of ships
IPC: B63B39/06
Filed: 1921-12-16
Abstract: 194,788. Motora, S., and Mitsubishi Zosen Kabushiki Kaisha. Dec. 16, 1921. Planes for preventing rolling.-In apparatus for preventing ships from rolling of the kind in which fins projecting from the ships side are controlled by gyroscopes so that they are automatically turned into positions to check rolling when such motion is initiated, the precession oi the gyroscopes is used to operate contacts which control electrical circuits actuating motors which operate the fins. Where a single gyroscope 11, Fig. 2, is employed, the spinning axis is athwart ship, and when precessing, the gyroscope rotates about a vertical axis against the constraint of spring-loaded stops 16 which finally are pressed back on contacts 17 which energize the solenoids actuating the valves or the switches of the controlling motor which operate the fins. In another form, a second, less sensitive gyroscope is brought into action and controls another circuit which operates the fins to an extent further than that allowed by the first gyroscope. A third and other gyroscope may be similarly employed. A suitable arrangement is shown in Fig. 3. A lever h controlling the valve or switch of the operating-gear at one end engages with a collar fixed on the shaft j. The lever is swung in the appropriate direction about the pivot i when either of the solenoids d, c is energized owing to the gyroscope a coming against one of the contacts f. The amount of swing of the lever is limited by stops k associated with the armature of a solenoid o. When the first gyroscope fails to control the roll, the second less sensitive gyroscope b effects the closure of a circuit including the solenoid o thus swinging the stops k out of the way and leaving the lever h free to swing over to open fully the valve. The hunting gear controlling the valve comprises a worm wheel w on a shaft x which is thus moved in one direction under the control of the lever h and is returned after a certain number of revolutions of the engine.

Title: Improvements in or relating to machines for winding yarn thread and the like
IPC: B65H57/14
Filed: 1930-11-15
Abstract: 367,032. Winding a number of yarns in close formation. LANGSTRETH, M., of Dunlop Cotton Mills, Osnaburgh Street, London, NASMITH, F., of Universal Winding Co., Saville Street, Oxford Road, Manchester, and DUNLOP COTTON MILLS, Ltd., Osnaburgh Street, London. Nov. 15, 1930, No. 34440. [Class 120 (ii).] In a machine for winding a number of yarns or threads side by side in closely related formation on a spindle 11, Fig. 1, a yarnguiding or tensiondistributing device 20 is provided between the yarn supplies and the spindle 11, the strands being led under tension in separated formation from their separate supplies to the device 20 and being caused to traverse the latter so that they take up a closely related formation in which they pass to the spindle 11. The device 20 affords a circular or conical surface for the strands which are given a complete or substantially complete turn therearound. The yarns pass from the supplies through breakage levers or stop-motion feelers 17 to the device 20 and over this range are separated and individually tensioned. In passage round the concave surface of the device 20 the strands take up a " tape " formation and from thence to the winding spindle 11 the strands support each other against the tension so that any breakage will occur before the strands leave the roller 20. After leaving the roller 20 the yarns pass over a guide roller 22, down to a second guide roller 15, through the traversing yarnguide 12 on to the winding spindle 11. The members 15, 20, 22 are adjustably supported on a bracket 13 carried at the top of the machine frame 10, the roller 20 being mounted on an adjustable spindle-extension 19 carried by an angularly-adjustable arm 18. In Fig. 1 two sets of yarns are shown passing over two rollers 20, two guide rollers 22, 220 thence down to the guide roller 15 and to separate yarn packages. The roller 20 is formed with a concave 'barrel 24, Fig. 3, supported by internal flanges 25 running on ball bearings 26 on a central spindle 27, stationary cheeks 31, shaped at 32 to overlie the ends of the barrel and flared at 33, abutting against collars 28, 29 on the spindle 27. In a modification, the barrel 24 is supported by flanges 34 carried by a selflubricating or like bush 35 on the spindle 27, Fig. 4.

Title: Improvements in or relating to casting apparatus
IPC: B22D17/14
Filed: 1958-10-29
Abstract: 855,156. Casting-machines. SAUTER, H., and HAHN, W., [trading as HAHN & KOLB]. Oct. 29, 1958 [Oct. 30, 1957], No. 34607/58. Class 83 (1). A casting-apparatus comprises means for connecting a mould cavity 3 to, or sealing it from, a source of vacuum, the connecting means 16, 17, 20, 26, being partly in the mould but out of the path of movement of the casting from the mould. Metal may be injected through a passage 8 into mould parts 1, 2, co-operating with a core 4. Air may be exhausted from the mould cavity by a connection 27, the passage 20 and the passage 16, which can be closed by the plunger 17 operated by a fluid-pressure piston 23 acting against a spring 18, or hydraulic pressure. The casting shrinks on to the ends of tubes 30 so that it is carried upwardly with the mould part 2 when casting is complete. The casting is then ejected by rods 31, 32. The cylinder for the plunger 17 is provided with air-cooling passages 37 to dissipate heat transferred from the mould. In operation, the mould parts are closed and a valve 55, Fig. 7, is opened, mechanically or electrically, to connect the mould with a vacuum chamber 54. A molten-metal reservoir 49 is then filled and a valve 41 operated causing the plunger 17 to be advanced to cutoff the vacuum connection and a plunger 57 to be advanced to inject the metal into the cavity, an opposing plunger being operated to open a connection 50 leading to the cavity. The end of the plunger 17 lies flush with the side of the mould cavity, its movement relatively to that of the injection plunger 47 being controlled by valves 51, 52. In a modification, the piston 57 is advanced by pressure from a pressure accumulator, and the piston 17 is moved to closed position in the opposite direction as shown in Fig. 5. The machine may be modified to load the reservoir 49 by vacuum suction. If the side of the mould cavity is steeply inclined, the plunger 17 may project slightly into the cavity as shown in Fig. 9, the arrangement being such, however, that upward movement of the casting is not hindered. In a further modification, several cavities 3, Fig. 4, are contained in the mould parts, each cavity having a core 4. The casting shrinks around rods 28, 30, which are moved upwardly relatively to the part 2 to free the casting. A single vacuum-connection is provided, but several connections which may be fitted in the movable mould part may be provided.
