Filed: 1936-11-18
Abstract: 485,375. Type-bar-making machines. MERGENTHALER LINOTYPE CO. Nov. 18, 1936, No. 31572. Convention date, Dec. 14, 1935. [Class 100 (iii)] Magazines.-In machines in which the magazines are carried in a pivoted supporting- frame D, which can be raised to permit the removal of a magazine over the assembler entrance I, the pivoted arms L, on which the magazine is supported during removal and replacement, are automatically moved into operative position by the adjustment of the frame D. The base-frames B of the magazines A are, as heretofore, fixed to side-plates C, so as to form a shift-frame, which is adjustable in the supporting-frame D, to effect the positioning of a magazine. The arms L, which are connected together by a rod L<3>, are connected by an arm L<5> and a link L<5> to the supporting- frame, so as to be actuated thereby. Each magazine is retained on its base-frame by the usual lugs B<1>, Fig. 3, which are engaged by a cross-bar A<1> on the underside of the magazine, and, in addition, by a cross-bar M engaging behind a pair of spaced members M<1> on the base-frame, the members having interlocking tongue-and-groove parts, to prevent upward movement of the magazine. The arms L have guideways L<4>, to receive plates N projecting from the sides of the magazine, and retaining- plates L<7>, which overlie the guideways for a part of their length, co-operate with the plates N to prevent tilting of the magazine. When the plates N have cleared the retaining-plates, the magazine can be tilted into the vertical position and suspended by the plates N from lugs L9 on the arms L.

Title: Semiconductor bodies and their manufacture
IPC: H01B1/18
Filed: 1966-07-14
Abstract: 1,088,734. Semi-conductor resistor. GENERAL MOTORS CORPORATION. July 14, 1966 [Aug. 16, 1965], No. 31608/66. Heading H1K. [Also in Division F1] A semi-conductor body consists of 50-80 wt. per cent SiC finer than 400 mesh (U.S. standard sieve), 15-35 wt. per cent metal silicate and 0-15 wt. per cent metal oxide, the metal silicate and oxide forming a non- conductive matrix which bonds the SiC. The silicate is preferably of Al, Zr, Mg, La, Be or Y, whilst the oxide is of Al, Zr, Mg, Be, La, Y, Ca, Sr or Ba. The SiC can be finer than 600 or even 800 mesh whilst it is preferable that the other materials are finer than 400 mesh. The body may be made by grinding together SiC and materials which will form a metal silicate on firing to which may be added fluxing agents such as talc, kaolin, SrCO 3 , BeO, MgO, CaO, SrO or BaO and an organic binder, e.g. wax, to facilitate handling. The ground mixture is moulded into the desired shape then embedded in SiC and fired at 2600-3150‹ F., however if a metal oxide is present it is essential to preheat the moulded body in air to 1800-2400‹ F. so that some of the carbide is oxidized and is thus able to form a silicate in the consequent firing step. The preheating step also changes the crystalline structure of some of the carbide from hexagonal to cubic. The body may be used as a sparking plug.
