Title: Improvements in or relating to game apparatus
IPC: A63F7/06
Filed: 1929-11-15
Abstract: 347,197. Games. WITHERS, J. S., 51, Chancery Lane, London.-(Putt-Well Golf Corporation ; Portsmouth, Virginia, U.S.A.) Nov. 15, 1929, No. 35013. [Class 132 (ii).] Apparatus for a golf putting game comprises a play board having a plurality of holes therein; means to indicate when a ball has passed therethrough, runways leading from the holes, ball return mechanism for receiving the balls from the runways, means for ejecting the balls from the return mechanism and means operatively connecting the ejecting and indicating means for resetting the indicating means upon ejection of the balls. The player stands on a platform 16, Fig. 1, and putts the ball up an incline terminating in holes 14 and in a rear trough 9 leading by means of runways and by a diagonallydisposed passage to a coin-controlled compartment 78 wherein the balls come to rest on an inclined floor 57, Fig. 13. In falling through a hole the ball displaces a weighted catch and permits a flag 36, adjacent the hole, to rotate under spring action and thereby indicate the success of the stroke. To obtain the balls, the player inserts a coin c into a slide 85, Fig. 21, and pushes in the slide to the position shown, by pressure on the button 91, thereby causing the coin to push back a pivoted latch bar 102 into the inclined position shown. The slide is retained by a spring-pressed detent 103. The lower end of the latch bar liberates a crank arm 67, Fig. 13, carried on a shaft 50 extending across the apparatus. The player now turns a hand-lever and thereby rotates the crank 67. The crank, operating through a resilient connection and through parallel arms 63, raises the ball-supporting floor 57 and discharges the balls on to the playing board down an incline 58. At the same time, the crank shaft 50 imparts a rotation to a disc beneath the board, and the disc acting through a number of connecting-rods resets the displaced flags 36 in engagement with their catches. The initial movement of the crank 67 also further displaces the latch bar 102 and liberates the coin which drops through the slide into the bottom of the box. The return movement of the latch bar, under the action of a spring, displaces the catch 103 and the coin slide may then be drawn out to permit of the insertion of another coin.

Title: Improvements in or relating to methods and apparatus for applying electron-emissive coatings to cathode cores of indirectly heated thermionic cathodes
IPC: H01J9/06
Filed: 1957-11-11
Abstract: <PICT:0823900/III/1> An indirectly heated cathode core 4 is coated with emissive material conveyed to it by rotating it against a coated roller 12 which passes through a reservoir 2 of the coating substance; the coating process is terminated by blowing a stream of air through a duct 5, which strips the coating from the roller, thus avoiding the formation of a "seam" on the cathode coating.  The roller 12 rotates in an opposite sense to that of the cathode core, and at a greater peripheral speed.  The coating paste which may be, e.g. a suspension of an alkaline earth carbonate mixture in a solution of nitrocellulose, is continuously circulated through a system 9, 8, 6 to maintain a constant concentration.  The cathode coating is also effected cataphoretically by applying a suitable potential difference between roller and cathode.

Patent GB-912690-A (GB)
Title: Tufting machine
IPC: D05C15/08
Filed: 1961-09-29
Abstract: 912,690. Tufting machines. CABIN CRAFTS Inc. Sept. 29, 1961 [Oct. 24, 1960], No. 35210/61. Class 112. A tufting machine comprises means for feeding yarn variably to a tufting needle for developing long and short tuft loops, patterncontrolled means governing the yarn-feeding means, a yarn guide movable to different positions corresponding to the development of long and short loops, and means acting on the yarn adjacent the movable yarn guide in one position thereof to develop a short loop by shortening the currently-formed loop. In Fig. 1, needles N carried by a vertically reciprocating needle bar 10 co-operate with loopers L fixed to an oscillating shaft 14 to produce tufts from yarns Y in a base fabric C. Each yarn is selectively fed to the machine at one of two speeds for producing either long or short tufts by pattern-controlled means, as described in Specification 853,943, and passes between loosely-meshing fluted rollers 20, 22, driven at the speed for producing the long tufts. The yarn then passes to the machine through successive fixed guides 16, 17 and 18. Between the guides 16 and 17 each yarn passes through a movable guide 30 connected to a piston 36 in a vertical cylinder 34. A spring 38 biases piston 36 upwardly, and a solenoidcontrolled valve 39 can admit compressed air to cylinders 34 for moving piston 36 to a lowered position. An L-shaped loop-shortening member 40 is fixed at the end of its longer limb to a shaft 42 adapted to be so oscillated that member 40 descends rapidly and rises again rapidly during each ascent of the needle. The shorter limb of member 40 can thereby engage the yarn between guides 30 and 17 to draw back a portion of the tuft in the process of formation. As shown, guide 30, the movements of which are also pattern-controlled, is in the lowered position and a long tuft will be formed, member 40 drawing back only a little yarn to ensure uniformity of tuft length. Alternatively, guide 30 when lowered positions the yarn outside the range of movement of member 40. To produce a short tuft guide 30 is raised, whereby member 40 is engaged with the yam during a greater portion of its downward movement. The fluted rollers 20, 22 ensure that member 40 draws yarn from the tuft and not from the feed. The loose mesh of the rollers allows slippage to occur between the yarn and the rollers when short tufts are being produced. In a modification, Fig. 4, the fixed guide 17 is omitted and a movable guide 30<1> has an upstanding limb providing a second movable guide 33<1>. For the production of short tufts, member 40 engages the yarn between the guides 30<1>, 33<1> in their raised position. For long tufts, guides 30<1>, 33<1> are lowered to position the yam beyond the range of movement of member 40. In Fig. 5, movable guides 30<3>, 33<2> carry two yarns Y<1> and Y<2> which pass respectively upwardly and downwardly from guide 30<2> to guide 33<3>.

Abstract: 1405293 Skis T P GALICH 27 July 1972 [30 July 1971 30 June 1972] 35230/72 Heading A6D [Also in Division F2] Two elongate planar members, e.g. sections of a collapsible ski, are. joined together in alignment by relative sliding between interlocking formations on the adjacent ends of the members in a direction normal to the planar surfaces of the members, the joint then being locked by passing a removable planar insert through aligned slots in the adjacent ends of the members, the slots being in a plane parallel to and intermediate the planar surfaces whereby the planar insert overlaps the interlocking portions so as to prevent the members from being slid apart in the normal direction, the ends of the members being of similar cross-sectional dimensions and the joint structure in its assembled condition having no protruding portions. In the embodiment of Fig 1, a dovetail slot 25 in one ski section 12 receives a dovetail tongue 48 on another ski section 14, and an insert 16 is then slid transversely into aligned slots 22, 42 in the respective sections to prevent sliding movement of the tongue normal to the upper and lower planar faces of the ski sections and thus lock it in engaged position in the slot 25. Screws engaging aligned threaded aperture portions 24, 44, 62, 64 secure the insert in position. The single dovetail tongue and slot may be replaced by multiple interlocking formations. Instead of a single insert 16, a pair of inserts may be slid into slots at opposite sides of the ski sections, each extending over less than half of the width of the ski (Fig 8, not shown). In the embodiment of Fig 10, metal plates 202, 204 having multiple dovetail formations adapted to interlock with one another are adapted to be embedded, by means of extensions 220, within the adjacent end of the ski sections, insert 210 being retained within slots 211 by at least one spring-loaded ball catch 216 the casing 212 of which is fitted within a bore in an associated one of the plates 202, 204 so that the ball engages in one of a set of notches 214 in the front and rear edges of the insert. The underside of the ski is made smooth by the provision of rebated portions 225, 226. The extensions 220 may provide anchorages for screws or equivalent hardware for fastening ski bindings to the ski.
