Title: Golf training device
IPC: A63B69/00
Filed: 1975-06-10
Abstract: 1472795 Golf training device M DE KREMER and P DE KREMER 10 June 1975 [1 April 1974] 14252/74 Heading A6D A golf training device comprises a guide 1, Fig. 1, along which a slide 10 is movable in response to a golf ball 23 being hit away from the device, the slide including a clamp gripping a portion of the guide to provide a frictional resistance to the sliding movement. In the Fig. 1 embodiment, the guide comprises two inverted L-shaped rails 2 and 3, the horizontal parts of which are gripped between upper and lower spring-urged plates (Fig. 2), which consitute part of the slide 10. The force exerted by the springs may be adjustable A string 22 connected to the ball 23 extends through hole 9 in lug 8, around a pulley 21 carried by the slide, to a fixed part of the guide, e.g. end member 6. The guide may bear a scale (not shown) over which the slide moves to indicate the range which would have been achieved but for the string 22. A lever 18 is manually operable to move the clamp plates apart and return the slide to its starting position (adjacent end member 5) after each shot. In use, the device is pivotally connected to the ground or a calibrated base (Fig. 5) by a pin through hole 7. The golfer attempts to hit the ball away from the device along the line of guide 1. Hooking or slicing the shot results in pivotal displacement of the device about the pin through hole 7. In the Fig. 4 embodiment, the guide comprises a channel-section bar 1' against which slide plates 11', 12' are urged by springs 27 acting through slide casing 24. Screwed caps 26 permit adjustment of spring pressure.

Title: Improvements in or relating to regulating systems for dynamo-electric machines
IPC: H02P9/32
Filed: 1948-05-27
Abstract: 671,646. Exciting dynamo-electric machines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 27, 1948 [June 2, 1947], No. 14339/48. Addition to 671,645. Classes 35 and 38 (iv). In a modification of the generator regulating system described in the parent Specification in which the exciter of the generator has two field windings, one controlled in dependence on the load voltage and the other on the generator output and its excitation voltage, a single field control winding, whose excitation is dependent on the load voltage is used, with additional regulation by a saturable reactor excited in dependence on the generator output and its excitation voltage so as to maintain the minimum value of excitation. The pilot exciter 30 of the A.C. generator 10 is selfexcited by a series winding 32, small adjustments being made on an adjustable shunt winding 34. The exciter control winding 36 is energized in accordance with the voltage of the load circuit through a reference network 42 fed through a transformer, this control being modified to maintain a minimum value of excitation by the saturable reactor 64. The network 42 comprises a non-linear impedance circuit 46 and a linear impedance circuit 48 connected through rectifiers 54, 56 to the winding. At a predetermined line voltage the rectifier outputs are equal and balance each other, but any departure from the required voltage is reflected as a current of an appropriate direction in winding 36. The saturable reactor 64 is connected across the supply to the network 42 and is controlled by a D.C. current which is derived from the rectified resultant of the generator voltage and current derived from transformers 44 and 88, 90, in opposition to the voltage tapped off from a potentiometer 26 across the generator field winding 20. When the generator field falls below a certain value, current flows such that the reactor 64 suitably modifies the action of the network 42 to sustain the field excitation. In modified forms the reactor may influence only the bridge 46 or 48.

Title: Improvements in photographic relief images
IPC: G03C5/315
Filed: 1944-07-28
Abstract: 581,479. Photographic emulsions containing developing agents. KODAK, Ltd., DAVEY, E. P., and SOPER, A. K. July 28, 1944, No. 14413. [Class 98 (ii)] A relief image is formed in a silver-salt emulsion layer by incorporating in such layer the necessary developing agent and developing the exposed material by immersing in a solution of an alkali or, in the case of a waterproofed support, by using a roller to apply the alkaline solution. The method is particularly applicable in the production of templates in which the metal sheet is sensitized by transfer from another support of a layer of a gelatino-silver halide emulsion containing, for example, hydroquinone or catechol, exposed, immersed in dilute sodium carbonate or hydroxide solution, the unhardened areas washed off in warm water and the template cut to shape. Diffuse oxidation of the developing agent is avoided by making the emulsion with a pH value of between 5 and 7. A sulphite or metabisulphite may be added to the emulsion and, if desired, to the alkaline bath. A cold solution of an alkali thiocyanate may be used in place of hot water to wash away the unhardened parts of the emulsion layer. The emulsion may be of silver bromide or bromiodide or silver chloride in gelatin or other similar colloid. In an example, 5000 grams of a contrasty gelatino - silver bromide emulsion with a pH value of 6 is mixed with 50-grams of hydroquinone in alcohol and 10 grams of potassium metabisulphite in water and coated to a thickness of 5-7.5 Á on to a waterproofed paper support. After exposure, it is immersed for 10-15 seconds in a 6 per cent solution of anhydrous sodium carbonate in water,. The emulsion containing the developing agent can be transferred from a temporary support either before or after exposure, e.g. as described in Specifications 554,292, 554,298-, 554,300 and 554,301. Specification 555,949 also is referred to.

Title: Normally open valve construction having a deformable bladder
IPC: F16K17/40
Filed: 1975-04-11
Abstract: 1485201 Valves C R OLSEN 11 April 1975 14958/75 Heading F2V [Also in Division E1] A normally open valve for one-time operation, e.g. in an oil-well drilling rig, comprises a metallic bladder 20 folded back upon itself in a crushed valve-open condition so that obstruction to flow is at a minimum. When uncrushed, the bladder is of tubular form sealing the flow passageways. To close the valve a piston 30 is driven along the tube by electrically igniting a squib 40 which in turn ignites an inhibited propellant 50. This drives the piston at a controlled slow rate to prevent shock waves in the controlled fluid. The squib may produce all the propellant gas without the inhibited propellant 50. Alternatively the bladder may be operated from a fluid pressure source. Fig. 9 (not shown) discloses an embodiment in which in the valve-open condition the folded bladder lies to one side of the fluid passageway.

Patent GB-154348-A (GB)
Abstract: 154,348. Kidner, H. R. Sept. 2, 1919. Actions: @pression-controlling; tune-sheets; winding-mechanism; cases.-The strength of current operating the electro-magnet for each note of an instrument is controlled by means of a variable resistance in connexion with a toothed lever which enters perforations in the tune-sheet to an extent determined by the width of the perforations. The Figure shows the apparatus for the control of one note-actuating means only. The wooden lever P, pivoted at Q and carrying the tooth R of wood, bone, &c. bevelled on three sides, carries also a lead which runs from the terminal to a metal wheel O on the end of the lever P. The wheel 0 bears, according to the movement of the lever P and against the action of a flat supporting spring attached to the bar N, on different turns of the coil exposed at the edge B of the rheostat. When the lever P is depressed by an unperforated portion of the sheet the wheel 0 is carried out of contact with the coil. When the tooth enters a wide perforation, causing maximum current to flow, the wheel also contacts with a rubber or felt-lined stop EF. To save current a long perforation in the tunesheet is gradually narrowed to the minimum width. The tune-sheet in passing over the slotted plate S is closely pressed thereagainst by a grooved roller. During re-winding of the sheet the levers P and teeth R are depressed by a plate T hinged to the plate S and actuated by the rewind lever. The cabinet containing the apparatus may be lined with thick felt to deaden noise, and may be some distance from the keyboard.
