Abstract: 1,041,203. Printers. HITACHI Ltd. June 19, 1963 [June 19, 1962], No. 24413/63. Heading G4H. In a matrix dot printer, the type elements are arranged on a rotary member, e.g. drum or belt, A type drum has n identical circumferential columns of elementary types (Fig. 4, not shown), each column being for one character position and containing seven types each consisting of a dot in a respective lateral position, and also two types for characters not easily divided up into dots (e.g. marks to be affixed to voiced and unvoiced Japanese Katakana). A pulse train for each of the m possible printed characters which may be built out of dots is produced by sensing a drum rotating with the type drum. Selected pulse trains are routed to the appropriate electrostatic printing heads by a relay matrix in accordance with character and column selecting signals from a computer. The m character rows of the matrix may be pulsed in turn by these signals, in each case all the columns in which that character is to be printed being pulsed simultaneously. Alternatively, each column-row intersection of the matrix may be selected or not (alone) in turn. With the above arrangement, printing speed is limited by the operating speed of the relays in the matrix. Fig. 9 (not shown), shows a modification in which two matrices are used alternately.

Abstract: 426,632. Spray carburetters. SOC. GENERALE DES CARBURATEURS ZENITH, 10, Rue Petitot, Geneva, Switzerland. Sept. 7, 1933, No. 24848. Convention date, Sept. 8, 1932. [Class 7 (iii)] A spiral spring 15 or a weight rotates the throttle spindle 6 and valve 5 towards the open position to an amount determined by the engagement of a screw 11 on the spindle with the end of a slot 10 in the hub of a loosely mounted control lever 8 by which the valve may be closed positively. Adjacent the spring 15, there is secured to the spindle a vane 22 dividing a sector shaped chamber 19 in two compartments 20, 21 communicating respectively through a port 27 with the induction pipe beyond the throttle valve and through a port 26 with the atmosphere or carburetter side of the throttle valve. The spring 15 and port 27 are so proportioned that excessive engine speed causes sufficient suction on the vane to close the throttle valve and this closure is rendered independent of the throttle valve position by varying the ratio of the cross-sections of the passages connecting the compartments 20, 21 with the induction pipe on the one hand and with the atmosphere or carburetter side of the throttle valve on the other hand. A passage 28 connects the suction chamber 20 through the spindle 6 to a slot 29 of varying width in the wall of the chamber 19 or the port 27, Fig. 6, communicates with a chamber 31 communicating by a series of ports 34 adjacent the throttle valve with the induction pipe, the position of the valve determining the number of ports affected by suction behind it. The Specification as open to inspection under Sect. 91 describes also a construction in which a piston controlling the vent of the float chamber is actuated by the suction beyond the throttle as modified by the suction in front thereof, this latter suction being controlled by the co-operation of a tapering slot in the throttle spindle with a passage communicating with the suction side of the piston. In other constructions, the piston controls a fuel valve between the float chamber and the nozzle or varies the suction in fuel passages leading to the nozzle. This subject-matter does not appear in the Specification as accepted.

Title: Boron-containing compounds
IPC: C22C1/00
Filed: 1959-07-21
Abstract: Two forms of crystalline boron arsenide are prepared by contacting the vapour of a volatilized boron compound with arsenic vapour at 700 DEG -1200 DEG C. in the presence of hydrogen.  At 700 DEG - below 900 DEG C. black empirical formula BAS in cubic crystals of unit cell length 4,78  is obtained, and at 900 DEG -1200 DEG C. the product is tan empirical formula B6As in orthorhombic crystals of unit cell dimensions a=9,710 , b=4,343 , and c=3,066 , although orthorhombic crystals are stated to be B5As to B7As.  The cubic form is converted to the orthorhombic form by heating at 900 DEG -1200 DEG C.  Boron halides, e.g. BCl3, may be reacted with excess As in the presence of 10% H2, preferably in an inert gas atmosphere, e.g. N2, A, or He. The arsenic may be vaporized from solid, or from decomposable As compounds.  Shaped refractory articles, e.g. crucibles, nose cones, turbine blades, deflectors, and nozzles may be prepared from orthorhombic boron arsenide.  Thus, pressed bodies may be sintered, with, or without, organic resinous polymer binders, at 1300 DEG -2500 DEG C., and hot pressing a moulded boron arsenide body at 1000 DEG -2000 DEG C. gives a refractory body where part of the arsenide has been decomposed to boron.  Both forms of the arsenide may be used as semiconductor materials, with or without other crystalline materals e.g. Si or Ge, and modifier impurities, e.g. Zn or Se.  Optical windows for test instruments, guided missiles, or space ships may be made of the arsenides, or may consist of a layer of the arsenide on quartz.  The orthorhombic arsenide has a characteristic wavelength transmission which permits its use for windows for furnaces, or nuclear reactors.ALSO:Shaped refractory articles, e.g. crucibles, nose cones, turbine blades, deflectors, and nozzles, may be prepared from orthorhombic crystalline boron arsenide.
