Although the pins 10, 12 are press fits in the holes 6, 8 they may be axially movable therein when subjected to the forces used to draw the bearing parts together. The pin 10 has a frusto-conical end 14, but the pin 12 has plane surfaces 16 and tapered surfaces 18, Fig. 6 so that it aligns the two machine parts when they are pushed together by moving them relatively in an arc about a linear axis A-A through the pin 10 but does not permit appreciable opposing forces to be created between itself and the pin 10. In Fig. 7B for example the tapered pin 12 shown shaded will cause the hole 26 to swing about the other pin 10 but will not cause the holes to try to increase or decrease their spacing distance. When the pins have been engaged in the parts 2, 20 as in Fig. 3, then further forcing together of the parts will cause the knurled ends of the pins to push into their upper holes so that the parts may come together as in Fig. 4.

Title: Process for producing carbon black
IPC: C09C1/50
Filed: 1950-04-27
Abstract: In the production of furnace carbon black by thermal decomposition of a gaseous hydrocarbon with oxygen enriched air or pure oxygen in an elongated uncooled and unobstructed reaction chamber, an inert gas at a temperature below 100 DEG C. and in a proportion of 0.5-8 volumes per volume of combustion mixture, is injected into the combustion mixture when 80-95 per cent of the hydrocarbon has been burnt or decomposed, so as to cool the mixture effluent from the reaction chamber to a temperature of 250 to 800 DEG C.  A formula relates the effluent temperature with the temperature of the combustion mixture prior to the injection of the inert gas, the temperature of the inert gas and the volume thereof required.  25-30 per cent of the oxygen required for complete combustion is employed, at least 20 per cent of this being provided by pure oxygen.  The hydrocarbon and oxygen containing gas are preferably injected into one end of the reaction chamber in contiguous alternate thin streams.  The inert gas is preferably nitrogen, but hydrogen, carbon monoxide or cooled combustion gases containing less than 30 per cent of carbon dioxide and water may also be employed.

Abstract: 969,632. Superconductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 27, 1961 [March 30, 1960]; No. 10121/61. Heading H3B. Two superconductor circuits each having two parallel branches are coupled by cryotrons to form a bi-stable arrangement which may be set by control signals to either of its stable conditions. Thin film cryotons may be used. The arrangement facilitates testing for faulty insulation between cryotron control and gate conductors. Bi-stable circuit arrangement.-In circuit 61, Fig. 2, current from source 63 flows either in path 60 or in path 64. In circuit 90, current from source 93 flows either in path 92 or in path 94. The two circuits are linked by cryotrons 70, 72, 74, 76. The circuits are set by signals on terminals 100, 102 and the state of the circuit 61 is detected by cryotrons 78, 80. The output may be taken from circuit 90. The ratio of the supply current to the actual current required  for a control conductor to drive a gate conductor resistive (the supply current factor) is critical if circuit 90 is to follow circuit 61 and latch it in a stable condition. Suitable factors are prescribed. AND gate, Fig. 3.-Separate sets of input terminals 100, 102 and 100a, 102a are provided for the two circuits 61, 90. The operation is speeded up if a signal is applied to two terurinals 100, 100a and 102, 102a.
