Abstract: 651,117. Making turbine blades. PACKARD MOTOR CAR CO. Nov. 29, 1948, No. 30951. Convention date, Dec. 10, 1947. [Class 83 (ii)] A gas-turbine blade is made from a strip 13 of uniform thickness by removing metal from one face thereof, except along its longitudinal edges 15, in order to provide a varying thickness substantially throughout the full length of the strip, folding the strip about a longitudinal line and shaping it, welding together the longitudinal edges of the strip and removing metal 16 from the welded joint to form the desired edge contour. Metal is preferably milled from one surface of the strip 13, Fig. 4, from a point at or' adjacent one end to the other end so as to produce a wall whose thickness decreases gradually. The strip is then formed around a mandrel 17, Fig. 5, and, after being removed therefrom, has its free longitudinal edges joined by a continuous, spot, or stitch electric-resistance, weld. The seamed edges of the strip are then ground to remove the excess metal 16 and produce the desired profile, after which the surface of the blade is polished.

Title: Improvements in amusement or race game apparatus
IPC: A63F9/14
Filed: 1922-11-13
Abstract: 203,956. Higuchi, M. Nov. 13, 1922. Race games, mechanical.-Appliances for playing a race game comprise a number of objects adapted to be moved along tracks by a driving mechanism which is actuated by a ball being thrown into a visible pocket. Imitation rabbits 15, Fig. 1, are caused to move up a sloping platform 14 by repeatedly projecting a ball 72 through a pocket 75. Each rabbit is mounted on a wheeled carriage 16, Fig. 2, adapted to run on a track 21 and connected through belts 38, 34 to a wheel 25 mounted on a pivoted support 26 and located adjacent to a wheel 22 driven by a motor 23. The support 26 acts as an armature to an electromagnet 28 so that when the magnet is energized, the support 26 is attracted and the wheel 25 engages the wheel 22, causing the rabbit to move up the track. Corresponding to each rabbit is a ball-throwing mechanism, Fig. 4, comprising a pivoted arm 73 which is connected through links to a lever 90 in such a manner that when the lever 90 is pressed down the arm 73 rises and projects the ball 72 through the ring 75. As the ball passes through the ring it tenporarily displaces a pivoted member 76 thus closing an electric circuit including the magnet 28 and a battery, and causing the rabbit to move up the track. The rabbit which approaches the top of the track first, automatically breaks the circuits for all the other rabbits, and is carried forward automatically to the top when a lamp 105 indicates the winning rabbit. The rabbits are returned to their starting positions by a main switch which causes all the rabbits to finish the course and return along the underside of the track 21. As each rabbit arrives at the starting position it automatically breaks its circuit and comes to rest.

Abstract: 720,076. Insulation for dynamo-electric machines. MASCHINENFABRIK OERLIKON. Dec. 8, 1952 [Dec. 13, 1951], No. 31099/52. Class 35. Slot conductors are insulated by pouring or moulding a layer of thermosetting resin, e.g. polyester or ethylene resins, around the bundle in an evacuated mould. As shown in Fig. 2, the part conductors 1 are separated by sheets 2 of paper or mica, the layers being secured by synthetic resin. The main insulation 3 is then cast around the bundle of conductors. To reduce the coefficient of thermal expansion of the resin, the conductors may be wrapped in fabric or fibrous material, e.g. raw mica, paper, or glass or asbestos cloth, before the application of the resin. Alternatively the resin may be weighted with inorganic substances, e.g. quartz powder or ground mica. The insulation may be covered with a metal coating 5, e.g. of wound on foil or sprayed metal, protected by an insulating covering 6, e.g. of wound fabric or moulded plastic, to ensure uniformity of electric field. Alternatively a semi-conducting layer may be used. The conductor is shielded where it emerges from the core by extending the metal coating 5 as shown in Fig. 3 and terminating it in a beading 8. Alternatively the metal coating may extend for only a short distance into the iron core, as shown. The coating 5 is earthed to the core by a connection, not shown, and is gapped at 9 to prevent circulating currents.

Abstract: 505,632. Cathode-ray tubes. DEHN, F. B. (Hygrade Sylvania Corporation) Nov. 12, 1937, No. 31145. [Class 39 (i)] In a hard cathode-ray tube provided with a fluorescent screen, a thermionic cathode and magnetic deflecting means, the beam is directed away from the screen and a magnetic field, which extends at right-angles to the beam axis, causes deflection of the elec. tron beam, before or at the same time as it is magnetically deflected to scan the screen, so that it impinges upon the screen while the direction of the beam of negative ions remains substantially unaffected. The tube neck may be bent or may be inclined to the axis of the enlarged end of the tube so that the negative ions do not reach the screen. In one form, a cathode 22, Fig. 3, control grid 23 and anode 26 are mounted on a ceramic disc 25; a mica disc 27 may support the anode 26 from the tube neck. The anode is bent so that the electrons are deflected by the field through the aperture 36 and the ions are caught by the diaphragm 30. The final anode may consist of a graphite coating to which connection may be made through a contact 9, Fig. 4. Scanning may be effected by two magnets 45,46 and the magnet 46 is additionally excited by current supplied from a battery 48 through a variable resistance 49 to produce a deflection of the beam. In a further form, the beam is deflected within the second anode 26a, Fig. 5, which is registered with respect to the first anode 26 by glass beads 26b. The graphite coating on the end of the tube may be connected to the anode 26a. Specification 442,511 is referred to.
