Title: Digital multipliers
IPC: H03H17/04
Filed: 1975-08-27
Abstract: 1476603 Digital calculating STANDARD TELEPHONES & CABLES Ltd 27 Aug 1975 35345/75 Heading G4A [Also in Division H3] A digital multiplier comprises an adder, an accumulator in which the adder output is stored and shifted one bit for each addition operation, and input means for applying simultaneously a plurality of serial data words to the adder cells, the input means being arranged so that each serial word so applied may be applied to one or more adder cell input lines simultaneously but no two serial words are applied to the same adder cell input line. Fig. 1, with adder ADD and accumulator ACC, uses a matrix for applying the serial data words D1, D2, which are binary, to form a weighted sum of these words, the weights determining the matrix connections established. Fig. 2 (not shown) shows a modification in which each matrix column can receive any one of three serial input words in either true or inverse (complemented) form (effectively ternary scale). Fig. 3 (not shown) shows another modification which is a fourth order recursive digital filter section and in which all but one of the serial data words used as input are obtained from the output of the multiplier via taps on a chain of one-word delays, the tap outputs being taken variously in true and inverse form, singly and combined (in serial adders). Also provided is a transfer register, loaded in parallel from the accumulator, to feed the (serial) output of the multiplier. The most significant four stages of the transfer register are sensed to determine if the allowable range has been exceeded: if it has, the multiplier output is adjusted to the positive or negative range maximum in an overflow correction circuit. Fig. 4 (not shown) shows a modification of Fig. 2 (not shown), having another adder between the matrix and the firstmentioned adder, this other adder receiving two columns of the matrix to each cell and having an add-subtract control line. Code conversion may be incorporated by appropriate choice of the matrix connections. The least significant carry input of each adder is grounded but may alternatively be used for extra data inputs, rounding, or automatic clearing of the accumulator. Fig. 5 shows a carrysave embodiment, with two (there could be more) adders, each having two data inputs plus a carry input to each cell, the right-hand output being the sum output and the left-hand output being the carry output. A sum accumulator A0-A6, a carry accumulator B0-B7, a sum transfer register S0-S6 and a carry transfer register C0-C7 are connected as shown, the contents of the two transfer registers being added serially at 50. Overflow detection and correction are shown, and also automatic clearing by feedback from 50. The error introduced by inverting for negative sign in the case of twos-complement data can be avoided using a compensation signal or replacing the inverters with suitable subtract-from-zero circuits. Application to digital filters for telecommunica. tions systems is also mentioned generally.

Title: Production of titanium
Inventor: GERNES DONALD CONSTANT
IPC: C22B34/12
Filed: 1954-12-08
Abstract: Titanium trichloride is formed by heating the tetrachloride, e.g. at 750-950 DEG C., in the presence of a reducing metal, such as titanium, aluminium or zinc, whose chloride is volatile at the reduction temperature and has a lower condensation point than titanium trichloride.  The trichloride is recovered from the gaseous reaction mixture by cooling to a temperature at which the trichloride is deposited, e.g. 450-600 DEG C.  The trichloride, preferably in the form of briquettes, is then disproportionated to form the di-and tetrachloride by heating to 550-650 DEG C. in the presence of a stream of inert gas such as argon containing not over 10 m.m. partial pressure of titanium tetrachloride.ALSO:Ductile titanium is produced by heating titanium trichloride in the presence of a stream of inert gas such as argon at a temperature of 550 DEG -650 DEG C. to form the tetrachloride and dichloride, separately recovering the dichloride, heating it in the presence of a stream of inert gas at from 700 DEG -1100 DEG C. to form titanium metal and the tetrachloride, and separately recovering the titanium.  The argon used in the disproportionation steps preferably contains not over 10 m.m. partial pressure of titanium tetrachloride for the heating of the trichloride and not over 2 m.m. partial pressure of tetrachloride for heating of the dichloride.  Titanium trichloride may be formed by heating the tetrachloride in the presence of a metal whose chloride is volatile at the reduction temperature e.g. 750 DEG -950 DEG C. and has a lower condensation temperature than titanium trichloride.  Such a metal as titanium, aluminium or zinc.  Titanium trichloride is separated from the gaseous reaction mixture by cooling to 450 DEG -600 DEG C. to deposit trichloride.  The trichloride, which may contain some dichloride may be agglomerated before being subjected to disproportionation.  The dichloride may also be agglomerated prior to the second disproportionation. Alternatively the trichloride may be introduced into a heating zone and heated up through the first disproportionation temperature range to the maximum temperature of 1100 DEG C. while passing inert gas through the zone.
