Title: Method and apparatus for permanently recording intelligence
IPC: G03G17/00
Filed: 1961-08-29
Abstract: 1,004,084. Ionic beam recording; televisions. MINNESOTA MINING & MANUFACTURING CO. Aug. 29, 1961 [Aug. 29, 1960], No. 31080/61. Heading G5R. [Also in Divisions H1, H4 and H5] A latent image is formed by bombarding a surface with a modulated beam of metallic ions and a permanent visible image produced by the subsequent step of vapour-depositing on the surface a coating of another metal. The ion beam formed in the demountable housing 10 by means of a metallic-vapour producing furnace 29 and an electron gun 25, 26, 27 is modulated by grid 30, accelerated by anodes 32, 33 and deflected by plates 35, 36 to impinge on recording tape 15. An electrostatic lens is provided at 37 and 40, 41, 42 are screens for stray particles. The vapour deposition step takes place in a chamber held at a lower pressure than the main housing, the vapour being produced in heated crucible 49. The tape 15 can be advanced continuously or step-by-step or a stationary sheet can be used which is removed from the apparatus and developed later. The beam need not be scanned over the recording surface, but may be directed on to the surface through a modulating plate, e.g. charged grid or master pattern. Suitable metals for the ion beam are copper, silver, beryllium, chromium and nickel and for the metal vapour copper, zinc, cadmium, barium, magnesium, lead or antimony. The developed image may be thickened by electroplating. Suitable material for the recording surface is barium sulphate-filled paper or a synthetic resin such as cellulose acetate, polystyrene, polyethylene terephthalate, ethylcellulose, polyvinyl chloride, methyl methacrylate or cellulose acetate butyrate either in sheet form or as a coating on e.g. paper, cloth, metal or glass plates. Metals or semi-conductors, such as cadmium sulphide or zinc oxide can also be used. Also mentioned are a fabric-reinforced phenol formaldehyde resin, polychlorotrifluorethylene, polyethylene and silicone rubber. The ion beam gun may contain oxygen which combines with the metallic ions produced so that a portion at least of the latent image may be formed by metallic oxides. The ions may be produced without the use of an electron gun, e.g. by means of an arc discharge.

Title: Pinsetter strike detector
IPC: A63D5/04
Filed: 1962-08-14
Abstract: 989,971. Bowling alleys. BRUNSWICK CORPORATION. Aug. 14, 1962 [Aug. 14, 1961], No. 31099/62. Heading A6D. A device for incorporation in a bowling alley installation to indicate a strike, comprises a switch in circuit with an indicator and mounted in the pinsetter control mechanism so as to be closed only when the pinsetter is operated after a strike has been bowled, and not when it operates after the second ball of a frame has been bowled. As particularly described, the device is incorporated in the pinsetter control mechanism disclosed in Specification 870,039, said control mechanism comprising firstly, a cam 17 which is arranged to rotate once each time a ball is rolled down the alley; secondly a lever 25 keyed to a rotatable shaft 26 and spring- urged to move towards the cam 17 but prevented from doing so by a latch except when the second ball of the frame is bowled; and thirdly a lever 13 and cam follower 15 normally prevented from co-operating with the cam 17 by a latch 21, 22 (not shown), said latch being released to permit such co-operation when the pinsetter mechanism is required to position a new set of pins on the playing deck, either after a strike, or after the second ball of the frame. Such co-operation results in the cam follower 15 dropping on to the lower region 20 of the cam 17, with the resultant pivoting of the lever 13. The strike indicating device comprises a mercury switch 39 mounted on a bracket 36 pivoted to the frame of the pinsetter control mechanism at 37, and restrained to move in coordination with the lever 13 by a pin 42 mounted on the said lever. Thus as the lever 13 drops to its pinsetting position, the bracket 36 drops to the position indicated in broken lines in Fig. 3 to allow the switch 39 to complete the circuit to the strike indicator. In order to prevent the switch from operating after the second ball of a frame has been bowled, a lever 43 is provided on the shaft 26, so that as the latter rotates after the said second ball has been bowled, the lever moves an arm 45 pivoted at 46 to prevent the switch 39 from dropping to its lowermost, operative position.

Title: Improvements in or relating to abrasive feed device for lens grinding and like machines
IPC: B24B57/00
Filed: 1950-12-21
Abstract: 732,103. Grinding lenses. THOMAS, R. E. and RODWAY, Ltd., G. Dec. 21, 1951 [Dec. 21, 1950], No. 31132/50. Class 60. A device for feeding abrasive to a lens-grinding machine comprises a splash bowl 2 surrounding the work with clearance, a rotary container 8 for abrasive-carrying liquid located below an opening 4 in the bottom of the bowl, a feed pipe 17 which is fixed in the bowl with its upper end directed towards the work and its lower end opening within the container, and means for rotating the container at such a speed that abrasive is flung by centrifugal force against the inner periphery of the latter and caused to travel up the feed pipe on to the work. The bowl 2 is supported on brackets 6 on the machine frame in surrounding relation to the driving spindle 5 of the lap 1. The container 8, which is preferably of greater diameter than the opening 4 in the bowl, is mounted on the spindle 5 and partially closed by an annular lid 9; the inner edge of the lid has a rim 11 which is provided with drain slots 13 and a series of superposed and inwardly-directed baffles 12. The feed pipe 17 is carried by a bracket 16 which is secured by a detachable clip 14 to a transverse bracket 15 mounted on the inside of the bowl. The pipe 17 has a swan-neck outlet at its upper end to direct the abrasive on to the lap, and a nozzle 18 at its lower end located close to the inner periphery of the container. An openended scoop 19 of flattened tubular section is disposed on that portion of the feed pipe disposed in the container, to provide for an intimate mixing of the abrasive particles in the carrying liquid. A seal in the form of a rubber thimble 23 is fitted on the spindle 5 to prevent the leakage of abrasive-carrying liquid into the machine bearings. The container 8 is removable, after detaching the bowl 2 and lap 1, and so may readily be replaced by another containing a different grade of abrasive, when such is required. The change from a lap requiring a continuous feed of abrasive to a diamondbonded lap requiring only a continuous supply of water may be effected by replacing the container 8 and feed pipe 17 by a fixed trough which is fitted with its upper open side in register with the outlet from the bowl 2, and a circular thrower plate is secured to the lap spindle so as to rotate therewith; a downward flange on the outer edge of the thrower plate dips into the trough so that any water or detritus falling on to the plate is deflected outwardly and into the trough.

Title: Improvements in and relating to overload cut-outs
IPC: H01H71/58
Filed: 1924-12-30
Abstract: 254,348. Marks, E. C. R., (Voigt & Hµffner Akt.-Ges.). Dec. 30, 1924. Automatic circuit-breakers are actuated on overload by a solenoid having a core h which strikes a detent g pivoted to a bridging contact arm f, releasing the detent from engagement with a disc k and allowing the arm f to rotate to the open position. According to the construction shown in Fig. 2, the members f, k are connected by a helical spring i and are held in the closed position by a spring l engaging a notch in the disc k. When the detent g is released, the disc k remains stationary and the arm f rotates into the open position under the action of the spring i. To reset, the handle c, connected to the disc k, is turned against the spring l, till the spring i is strained again and the members f, k are again locked by the detent g. The handle is then turned back to bring the parts into the closed position. In a modification, Fig. 4, the spring i is fixed at one end to the casing, and the disc k has two diametrically-opposed shoulders either of which can engage the detent g and a further two diametrically-opposed shoulders either of which can engage an additional detent n. In this case, to reset, the handle c and disc k are rotated in a direction opposite to that in which the arm f has moved when opening, till the previously disengaged shoulder engages the contact g and carries it and the arm f back into the closed position, where they are held by the latch n engaging the other previously disengaged shoulder. Release by hand is effected by pressing a rod o. In another modification, Fig. 6, release may be effected by turning backwards the handle c, a finger r attached thereto, engaging the detent g and unlocking the arm f which moves to the open position under the action of a spring i between the members f, k. The disc k is held stationary during this movement by a catch p till the latter is moved aside by a pin f<1> on the arm f. The disc k then follows the arm f under the influence of a spring q. The automatic release action is similar. The switch is reset by turning the handle c which is connected to the disc k by a spring t and shaft s. This flexible connection allows the handle to be turned back to release the switch, but, during resetting, a positive drive is obtained by a pin u engaging a slot in the sleeve attached to the handle. Fig. 7 shows another modification in which release may be effected by depressing a button v in the handle c and so causing abutments w on the disc k to move out of engagement with fixed projections x.
