Title: Magic game
IPC: A63F3/00
Filed: 1975-11-12
Abstract: 1458930 Board game; toys MARVIN GLASS & ASSOCIATES 12 Nov 1975 [18 April 1975] 46722/75 Headings A6H and A6S [Also in Division E2] A game comprises a board defining a track having marked spaces indicating that certain magic tricks should be attempted and the apparatus for attempting such tricks. The game includes playing pieces, instruction cards, a dice and play money. One trick consists of applying a toothed saw to a pinion 72, Fig. 7, and simulating sawing a woman in half. When a player has finished sawing, he attempts to pull the halves 54, 56 of the apparatus apart. If a tab 78 on the pinion is in a downward position the halves separate and the trick is successful. Spring clips normally hold the halves together. In the second trick, a body 140, Fig. 10, to be "levitated" is supported on a table 106 pivoted on an axis 110 and resting on a trestle 142. If a knob 132 is turned so that a tab 134 engages a projection 118 on the table, the body remains horizontal when the trestle is removed. Otherwise, the table tips about the pivot axis and the trick is unsuccessful. In the third trick, a body 158, Fig. 12 vanishes if a cover 150 has been positioned so that a magnet 160 on the head engages a washer 156 in the roof 152. If unsuccessful, removal of the cover 150 reveals the body still in place. The cards can be bought and sold.

The detector is carried by a centrifugal rotor 17. When a projectile fitted with the fuze is fired, the detonator becomes aligned with the firing pin; and a centrifugal band 22 unwinds to release a plurality of segments 21 blocking the hammer body. The hammer sleeve is then only held still by the action of centrifugal balls 23 which bear against a conical surface 25. Upon impact of the projectile, the hammer sleeve 15 and the inertia body 26 are forwardly accelerated and supplement the action of the spring 20 in driving the firing pin into the detonator. The inertia body 26 may have various shapes, Figs. 2 and 3 (not shown).

The total organic matter in an aqueous liquor is determined by oxidizing a sample of the liquor by bringing it into contact with a solid oxidizing agent which is insoluble in the liquor, reducing the carbon dioxide so formed to methane by mixing it with hydrogen and bringing the mixture into contact with a suitable catalyst and quantitatively measuring the methane formed by means of a flame ionization detector. In the arrangement shown in Fig. 1, the sample is injected from a syringe (not shown) inserted through a silicone rubber seal D and extending into the oxidizing agent B, which may be copper oxide at 850-900‹ C. A stream of nitrogen carrier gas is admitted at E. The catalyst K for the reduction comprises firebrick having a layer of adsorbed nickel at 300-350‹ C. Hydrogen for the reduction is a 1:1 v/v mixture of hydrogen and nitrogen admitted at I. A drying tube L contains self-indicating silica gel and a further drying tube M contains silica gel. Burner gas for the flame ionization detector is a 1:1 v/v mixture of hydrogen and nitrogen admitted at P. Air is supplied at S. Known samples of methane may be injected through a silicone rubber seal H for calibration purposes. Also, if the liquor contains a significant amount of carbon dioxide, this can be determined by injecting a sample through seal H. An auxiliary heater G ensures vapourization of the sample.

Abstract: 1,159,456. Testing bonded joints. INTERNATIONAL BUSINESS MACHINES CORP. Nov. 9, 1966 [Nov. 15, 1965(2); April 25, 1966], No. 50092/66. Heading G1S. An apparatus and method for testing a bonded joint between an electrical component and a substrate comprises subjecting the bonded joint to a blast of a fluid medium and monitoring the bonded joint for changes in electrical resistance during said blast. In the embodiments described the components under test are micro-miniature electronic devices attached to a printed circuit board. In one embodiment Fig. 3 the modules 411 under test are placed on firing sticks 419 which are fed sequentially between rollers 432N, 432S, 433N, 433S, 434N and 434S. While passing between the rollers the modules are subjected to a blast of air under pressure so that a weak bond can be detected. The module is placed in circuit with a source of current so that if the bond is broken the break is detected since no current will flow in the circuit or if the bond is just weakened the resistance of the circuit will be decreased. In a second embodiment Fig. 11 the modules 11 are placed on firing sticks 12 and fed along conveyors 41 at the end of which they are placed on sprockett wheel 52 which convey them to a carrier table 24. At the carrier table 24 the modules are removed from the firing sticks and placed in recesses in the table 24. As the table 24 rotates the modules are moved through various stations, at one of which the module is subjected to a blast of air from a nozzle mounted on the table 36. If the module is not faulty it is removed from the table 24 at the next station and placed on a firing stick which has been moved into place by conveyors parallel to the first conveyors and further sprocket wheels. If the module is faulty, detected as described above in connection with first embodiment it passes the next station and at the next after that it is removed from the table and placed in a disposal chute. The functions of the apparatus are controlled electrically in such a way that if a faulty module is detected, the means which removes the modules on to the firing sticks after testing is not actuated and also the firing stick is not progressed.
