Title: Game practice means
IPC: A63B69/36
Filed: 1963-07-04
Abstract: 1,002,524. Electric selective signalling. J. M. SCHINE. July 4, 1963 [July 31, 1962], No. 26475/63. Heading G4H. [Also in Division A6] In apparatus for practizing golf a ball is propelled from a tee 10, Fig. 1, towards a target 19, the tee having a photo-cell responsive to the departure of the ball and the target being flexible and having 4 inertia switches 21 responsive to the shock of the ball reaching the target, there being means for measuring the time between the actuation of the photo-cell and the target switches. The tee 10, Fig. 2, consists of a flexible tube 36 having the photo-cell 35 at the bottom. Set slightly forward of the tee are transducers 43, 44. These respond to defective strokes of the club, the transducer 43 on the right detecting " slice " and that 44 on the left detecting " hook " when struck by the club the inertia switches 21 each consist of a housing 20, Fig. 5, and a contact 28 mounted on a spring 25. The time period is measured by discharging a capacitor from the time photocell 35 is exposed to the time one of the switches 21 operates. The faster the ball is travelling, therefore, the shorter the discharge time and the higher the remaining voltage on the capacitor. This voltage is transformed into an approximate indication of the distance the ball would have travelled if it had not been stopped by the target. For this purpose a rising stair-case voltage is generated by a stepping-switch potentiometer stepped by a relay flip-flop circuit. The charge on the capacitor is applied to the guide of a gas-tube and the staircase voltage is applied to the cathode. The gas-tube accordingly acts as a comparator, firing as soon as the change on the capacitor is exceeded by the stair-case voltage. The output from the gas-tube interrupts the stepping. Other banks of the stepping switch are connected to a display board of lamps indicating the distance the ball would have travelled. The " slice " and " hook " detectors 43, 44, if actuated, cause the indication to be transferred through other stepping switch banks to another display board together with " slice " or " hook " indication.

Alkali &c. metal may be driven off from the coated member during operation of the cell by heating. A silver bead, not shown, is mounted on a filament 7 and is vaporized by heating the filament so as to form a deposit on the envelope, the anode 8 preventing deposition on the window 11, and a glass disc 12 prevents deposition on the neck. The silver coating is oxidized by admitting oxygen at a pressure of 1 to 2 mm. of mercury and heating the bulb in an exhaust oven to 360‹ C.; or a high voltage, high frequency potential may be applied between the cathode and anode. Caesium, rubidium, or potassium is admitted through an extension 14, and the coated disc 6 is heated to prevent absorption of caesium. &c. thereby. Instead of silver, the foundation metals deposited on the envelope, or on plates or cylinders may consist of magnesium, calcium, copper, nickel, tungsten, or barium.

Abstract: 1399521 Laminating plastics films MOLECULAR DESIGN Inc 9 June 1972 [11 June 1971 2 June 1972] 27062/72 Headings B5N and B5B A method of laminating at least two chemically dissimilar plastics films one to another by binding surfaces of the films together to form a laminated sheet, comprises subjecting each of said film surfaces to an electric corona discharge treatment and bringing said film surfaces together under pressure, the intensity of the electrical corona discharge treatment applied to each surface being predetermined such that the laminated sheet has a peel strength based on a one-inch wide strip of laminated sheet, tested at 72 F. of at least 200 gms. The method may be used for bonding a polyolefine film, e.g. a film of polyethylene, polypropylene or an ethylenepropylene copolymer to a film of an olefinic nitrile polymer, e.g. an acrylonitrile polymer, a an acrylonitrile polymer, a polyamide, e.g. nylon 6, a polyester, e.g. polyethylene or polytetramethylene terephthalate or a polymer obtained by polymerizing a major proportion of an olefinically unsaturated nitrile, e.g. acrylonitrile, with a minor proportion of an olefinically unsaturated carboxylic acid ester, e.g. ethyl acrylate, in the presence of a nitrile rubber, e.g. an acrylonitrile-butadiene copolymer. The films used in the method of the invention may be freshly extruded or may have been stored prior to or subsequent to the corona discharge treatment. Contact of the films is preferably effected at elevated temperature, a minimum amount of pressure, e.g. the force required to draw the films together over a roller being used. Each film may be treated by separate electrodes; alternatively, a single electrode pair is used. Many suitable arrangements of apparatus for use in the method are disclosed.

Abstract: 1,261,785. Welding by fusion. OSAKA TRANSFORMER CO. Ltd. 29 May, 1969 [3 June, 1968], No. 27169/69. Heading B3R. [Also in Divisions G3 and H2]  Arc welding apparatus of the type employing short-circuit transfer between an electrode 3 and the workpiece 4, is provided with an electrode feed control system which uses the arc voltage to supply the electrode feed motor 8 and so regulate the feed speed to maintain the arcing period substantially constant. The motor 8 is connected to members 3, 4 through a silicon controlled rectifier 7 whose firing signal is derived from a trigger circuit 9 supplied via terminals c, d from the voltage across members 3, 4. Thus the appearance of the arc voltage fires the rectifier 7 to energize the motor 8, whose speed is dependent on the duration of each arc period so that a tendency for this period to increase or decrease will respectively increase or decrease the feed speed to compensate the period variation. To prevent the motor 8 receiving the fluctuating arc voltage occurring immediately after the commencement of the arc period, the circuit 9 delays the firing of the rectifier 7 until the arc voltage has attained a relatively stabilized value, Fig. 2 (not shown). The arrangement shown in Fig. 4 provides this time delay and also provides a stabilized voltage for the motor PM, which voltage is independent of the minor fluctuations of arc voltage occurring during the relatively stabilized period. The time delay is provided by members R2, C1 which fire a unijunction transistor UJT to produce a firing pulse for rectifier SCR via windings PT, S of a pulse transformer. The feed motor PM receives a stable voltage determined by Zener diodes VRD1, VRD2. Typical characteristics relating arc voltage, feed speed and time delay are discussed, Fig. 5 (not shown).
