Patent GB-1029939-A (GB)
Title: Improvements in or relating to data processing apparatus
IPC: H04L12/54
Filed: 1963-09-30
Abstract: 1,029,939. Telegraphy. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 30, 1963 [Oct. 15, 1962], No. 38359/63. Heading H4P. In a telegraph exchange a control word is associated with each line for holding data bits and control information. The lines, and hence the stored control words, are scanned sequentially. As described, the scan rate is so fast that an operation on the control word (e.g. removal of one bit forming a character and replacing it with the next bit) takes longer than the relevant control word is available, and the new bit is thus added to the wrong control word. Each control word comprises a number of " correct " and a number of " wrong " bit places, and the invention provides an apparatus wherein a bit entered in the wrong word (i.e. in a " wrong " bit place) is gradually transferred to the " correct " place in the right word. The transference of such a bit from one word to the next takes place direct, whereas the remaining part of the word is passed through the logic section of the exchange and read in to the store in the time-position assigned to that word. In Fig. 1, thirty outgoing lines LA, LB, LC feed remote printers and are scanned in the order A1, A2, A3; B4, B5, B6; C7 &c., but bits are sent only on the first line in each group, i.e. on A1, B4, C7 &c. Whenever a bit is sent to line a new bit is requested from source 1. By the time the new bit arrives on source output 2 the line being scanned will be two ahead of the one for which the new bit was requested. This new bit will therefore be fed in to the wrong control word. Each of the three units MCA comprises a circulating delay line store, this store containing nine ten-bit control words and one bit of the tenth word, the remaining bits of the tenth word being held in a logic unit; the ten words circulate through the store and logic. Whenever bit positions 6, 8 or 10 are read from the store the bits by-pass the logic, which introduces an 8-bit delay, and are read into the store direct. Thus, bit 8 in one word is written into bit-place 10, and on the next circulation passes to bitposition 2. Bit-positions 6, 8, 10 are " wrong " bit-positions. The timing of the arrangement is such that new bits read in to the wrong control word eventually arrive at the right word in position 2. Transference to the right word takes place before the associated line is next required to transmit.

Abstract: 1,131,910. Radioactive isotopes. UNION CARBIDE CORP. 22 Aug., 1967 [17 Jan., 1967], No. 38525/67. Heading G6R. Technetium-99m (Tc-99m) is produced by extracting an aqueous solution containing Mo-99 and Tc-99m with an organic solvent, separating and drying the organic phase with a dehydrating agent, evaporating the organic solvent leaving Tc-99m as a residue, and taking up the residue in a liquid. An irradiated or fission product Mo compound, e.g. MoO 3 , is dissolved in an aqueous solution containing a salt, acid, or alkali, e.g. a concentrated solution of K 2 CO 3 ; hydrogen peroxide or bromine may be added to bring the Tc to its highest oxidation state. The Tc is preferentially extracted with methyl ethyl ketone, and the organic layer is washed with Na 2 CO 3  solution and dried with anhydrous K 2 CO 3 . The solvent is removed by evaporation and the residue dissolved in a pharmaceutically acceptable saline solution for use in medical research or diagnosis. The isotope may also be used in measurement of flow rates, process control, and radiometric chemistry. Other specified Mo compounds, salts, acids, and alkalies, organic solvents, and dehydrating agents may be used.

Title: Salts of polymers having repeating lactone rings substituted by carboxylic groups and the use of said salts as antistatic agents
IPC: G03C1/835
Filed: 1962-10-16
Abstract: The invention comprises salts of polymers having repeating lactone rings substituted by carboxylic groups as claimed in any of Claims 1 to 3 and 13 of the parent Specification (as amended Feb. 5, 1965). Preferred salts are alkali metal and ammonium salts.  The salts may be prepared by adding an aqueous solution of a base to a solution or dispersion of the polymer in an inert liquid so that the pH of the mixture during addition does not exceed 7. The resulting salt may be recovered by precipitation with a non-solvent such as acetone. The polymer salts may be used to give anti-static castings on film base, e.g. of cellulose acetate, and other substrates.  Examples describe the preparation of sodium, ammonium and lithium salts of polymers according to the parent Specification and prepared by reacting vinyl acetate/maleic anhydride copolymers with glycolic acid and n-butanol.

Abstract: 995,775. Transistor oscillators; automatic exchange equipment. GENERAL ELECTRIC CO. Ltd. Oct. 17, 1963 [Oct. 17, 1962], No. 39297/62. Headings H3T and H4K. A ringing-tone generator comprises two multivibrators 1 and 2 arranged to operate at relatively low and high frequencies (50 c/s. and 400 c/s.) respectively, the arrangement being such that the higher-frequency multivibrator 2 can oscillate only when a predetermined one of the active elements of the other multivibrator 1 (i.e. transistor 7) is conductive so that, in operation, the circuit generates bursts of oscillation of the higher frequency which recur at the lower frequency. In the circuit illustrated the energizing current for multivibrator 2 is supplied through transistor 7 so that multivibrator 2 only operates when transistor 7 is conducting. The production of ringing tone is controlled by switching signals applied between terminals 21 and 22, the signal applied comprising positive-going inhibiting pulses alternately of 200 milliseconds and 2 seconds duration spaced at intervals of 400 milliseconds. The keying may alternatively be effected by a relay whose winding is supplied from terminals 21, 22 and having a contact connected in line 20. Output is taken from emitter follower 25. Thermionic valves may be used instead of transistors.

Title: Improvements in alarm annunciators
Inventor: ROSS WILLIAM ANDERSON
IPC: G08B23/00
Filed: 1960-11-16
Abstract: 999,757. Transistor switching circuits. COURTAULDS Ltd. Nov. 15, 1961 [Nov. 16, 1960], No. 39305/60. Heading H3T. [Also in Division G4] An alarm annunciator is actuated when a normally-closed switch C 2  and a normally-open switch C 3  simultaneously open and close, respectively. An alarm is given by a lamp flashing due to a transistor T3 being rendered intermittently conducting by a generator 2 producing negative square-pulses. When a push-button switch C i  is opened to interrupt the circuit of a transistor T 2 , transistor T 3  conducts continuously owing to the potential of point B becoming that of a line L 2  which provides a smoothed negative h.t. Thus, a transistor T 1  also becomes conducting and reduces the potential of point C to that of a line L 4  which is maintained at zero potential, whereby release of switch C 1  does not cause transistor T g  to become conducting again. When transistor T 3  is continuously conducting lamp 1 produces a steady light. Restoration of switches C 2 , C 3  to their normal state returns the annunciator to its original condition and extinguishes lamp 1. The alarm annunciator may be actuated by only one or other of switches C 2 , C 3 , terminals 3, 4 being opencircuited or short-circuited accordingly. An audible-warning device may be provided in place of lamp 1.

Aug.29, 1967 [Aug.27, 1966], No.39530/67. Heading G3R. [Also in Division B1] The rate of formation of layers of crystallization of metal or semi-conductor from a melt is measured and compared with a desired rate so that any error is effective to vary the rate of supply or removal of heat and thus correct the rate automatically. As applied to the formation of metal rod by continuous electro-slag melting of an electrode or to the formation of semi-conductor rod by continuous crystal growing as the rod is withdrawn from a bath of molten material, measurements are made of voltage, current and frequency of an electrical supply to the crystallization zone and the rate of electrode feed or crystal withdrawal. The frequency of variations of current, being indicative of the rate of production of crystal layers, is compared with a desired rate so that any difference is effective to correct the rate by varying the rate of supply or removal of heat. Variations of resistance, computed from values of current and voltage and being indicative of the thickness of the crystal layers, are automatically corrected by variation of the rate of withdrawal through a control system involving differential and integral components of control. Automatic control of the electrical supply is also referred to.
