Title: Improvements in or relating to processes for the manufacture of beryllium or alloys thereof
IPC: C22B35/00
Filed: 1936-12-03
Abstract: Beryllium is produced by first forming beryllium sulphide by heating beryllium chloride with a carbonaceous material such as low temperature carbonization coke in sulphur vapours and/or a gaseous or vaporized non-metallic sulphur compound, e.g. carbon bisulphide or sulphuretted hydrogen, and then reducing the beryllium sulphide to the metal.  Equal weights of beryllium chloride and carbonaceous matter may be heated to about 1200 DEG  C. or preferably to about 1250 DEG  C., or, according to the Provisional Specification, to about 900-1200 DEG  C.  Reduction of the sulphide may be effected by heating it in a stream of hydrogen at 1350 DEG  C. or more, hydrogen sulphide being evolved, or in admixture with powdered aluminium in a current of hydrogen, aluminium sulphide and beryllium being obtained. The beryllium sulphide may be mixed in both of the above reducing operations with a flux such as beryllium fluoride or barium fluoride or a mixture thereof.  The beryllium may be distilled, there being present in the condensing chamber, if desired, molten metal such as copper, nickel, aluminium, magnesium, lithium, or the alkaline earth metals, whereby alloys are obtained.ALSO:Beryllium is produced by first forming beryllium sulphide from beryllium chloride and then reducing the beryllium sulphide to the metal.

Title: Data processing system timing
IPC: G06F3/09
Filed: 1965-10-26
Abstract: 1,134,004. Selective signalling. SCM CORP. 26 Oct., 1965 [26 Oct., 1964], No. 33175/68. Divided out of 1,134,003. Heading G4H. In a data processing system comprising means for reading a first record medium and means for re-recording information read by said reader on to a second record medium, the reader being operable in an automatic or a single-step-at-atime mode, a key which is provided for advancing the second record medium continuously as long as the key is operated functions to advance said second record medium through a distance sufficient for only a single item of information regardless of the duration of operation of the key when said single-step-at-a-time mode is selected. In the embodiment described, the record media are paper tapes and the invention is applied to the accurate preparation of field control tapes for securing to the carriage of a typewriter in a data processing system as described in the parent Specification. Automatic operation of the paper tape reader is controlled step-by-step by a source of constant frequency pulses (multivibrator 113, Fig. 6, not shown.) A " punch feed " key is provided operating a switch whereby pulses from said source may be gated to a solenoid controlling the step-by-step advance of the paper tape in the punch. A " single step " key is provided, depression of which to a first position closes a switch contact (1122) to select a single-step-at-a-time mode of operation for the reader wherein said source is disabled through first gating means (AND-gate 1106). On further depression of the " singlestep " key to a second position, a switch (1135) is momentarily closed, whereby a second gating means (AND-gate 1125) is operated to enable said source of pulses, a monostable multivibrator (114) is operated by a pulse gate (1138) armed by closure of the momentary contact switch (1135) and triggered by clock pulse generating means responsive to pulses from said source, and third gating means (OR-gate 1126) responsive to the operated state of said monostable multivibrator operates to disable said second gating means. Each successive depression of the single-step key to said second position thus enables said source to generate only a single pulse. The monostable multivibrator and said second gating means are alternatively responsive to the " punch feed " key if the " single-step " key is already depressed to its first position, whereby the single-step-at-a-time mode is made to apply to the punch instead of the reader.

Title: Improvements in or relating to ferraris electric meters
IPC: G01R11/36
Filed: 1937-12-03
Abstract: 493,242. Supply meters. SIEMENSSCHUCKERTWERKE AKT.-GES. Dec. 3, 1937, Nos. 33540, 33541, and 33542. Convention dates, Dec. 3, 1936, Dec. 10, 1936, and Oct. 6, 1937. [Class 37] A magnetic shunt for the driving flux of the current magnet of a Ferraris meter is provided with a magnetic member displaceably arranged in the neighbourhood of a point at which the reluctance of the shunt varies, so that it may be moved from the part of the shunt of lower reluctance to the part of higher reluctance in order to adjust the fault curve at high loads. In the construction shown in Fig. 1, the inner pole tips 3, 4 of the current magnet core have between them a shunt N having a part 2 of smaller cross-section than the part 1. A member P of magnetic material is adjustable along the shunt N. When the member P is moved in the direction of the arrow the length of the part 2 that becomes saturated at high loads is shortened. The members P,N may be of materials having different magnetization curves, in which case the fault curve is varied both at high and low loads by adjustment of the member P. In a modification, Fig. 2, the thicker part 1 is in the centre of the shunt N, the adjustment being effected by two iron vanes 8 pivoted at 7. The vanes 8 may be replaced by a single vane pivoted at its centre or by two sliding members fitting over a shunt of dovetail section. In the construction shown in Fig. 5, double vanes F are pivoted on the shunt N, the parts 5 being of larger crosssection than the parts 6. The vanes F may be pivoted on the edge of the shunt, or a single vane may be pivoted so as to be parallel to the plane of the shunt. In a further modification, Fig. 8, a regulating member 8 shaped as shown is pivoted at 7 to the tongue 5 of the return member 4 attached to the potential magnet. The magnetic shunt between the series magnet poles has its central portion of reduced cross-section. The smaller dimension d of the member 8 is substantially'equal to the width b of the tongue 5, the larger dimension D being substantially equal to the length of the constricted central part of the shunt.
