Patent GB-1353135-A (GB)
Title: Data processing system
IPC: G06F11/22
Filed: 1972-11-10
Abstract: 1353135 Data processing INTERNATIONAL BUSINESS MACHINES CORP 10 Nov 1972 [25 Nov 1971] 51962/72 Heading G4A Processing modules connected in series with each other and with a control unit by a bus having address lines L1 (Fig. 3) and data lines RB<SP>1</SP> each include a comparator COMP comparing the module address from an address generator in the module with the address on the address lines, a parity check circuit PCH1 for the transmitted address signal, a parity bit generator PCH2 for the data on the data line and means for transmitting to the control unit the module address together with the signal from the parity check circuit PCH1 and/or the signal from the parity bit generator PCH2. The system performs tests to determine (1) whether the addressed module replies, (2) whether the address bus is operating correctly and (3) whether the data bus is operating correctly. (1) If a module receives its correct address, comprising unit address bits UADR and detailed address bits DADR, its comparator is triggered to enable OR gate 02, a decoder DEC enabling OR gate 01 so that AND gates A3 are enabled to transmit a reply byte from reply register REP-REG, the byte including the module address. AND gates A1 are inhibited by the inverted output of OR gate 02 to prevent the address being transmitted to the next module, a pattern generator being enabled to send the zero address (with its correct parity). (2) If there is a fault in the address line, parity check circuit PCH1 in the first module detects a parity error and triggers both OR gates 01, 02 so that the address of this module is transmitted back together with a bit (inserted in position 4 of the reply register) indicating the parity fault. (3) The data bus is tested in a closed ring and to each unit. The former is effected by applying an invalid address to the address line and a sequence of test patterns to the data line. At each module the test pattern is entered into a register RB<SP>1</SP>-REG and fed via gates A2 (enabled since the module is not addressed) to the next module and output data lines RB<SP>1</SP>. This tests for "open", "earthed" and "shunted" lines. Each module is then addressed in turn. The parity circuit PCH2 in each module computes a parity bit for each test pattern and feeds it to position 5 of the reply register. Parity check circuit PCH1 is also tested at this time since it feeds a bit corresponding to the parity of the input address to position 4 of the reply register. The address bits and bits representing a module error or module request are also entered into the reply register. AND gates A3 in the addressed module are enabled to transmit the reply byte to the output data line.

Abstract: 1,099,660. Control of A.C. motors. GENERAL ELECTRIC CO. Nov. 28, 1966 [April 27, 1966], No. 53200/66. Heading H2J. A reversible two-phase induction motor 100 has a control winding supplied sinusoidally from A.C. source 90 through power transistors Q5- Q 8  which are pulse-controlled by transistors Q 1 -Q 4 . A source 10 responds to a servo command and a feedback signal from transformer T 9  to provide a variable amplitude, bi-polarity, D.C. signal to saturable transformers T 1 -T 4  whose cores have matched square-loop hysterisis characteristics to provide integration. Square-wave signals are applied to the transformers, synchronized with the A.C. power, and having the same frequency. A D.C. bias is also applied to the transformers. Transformers T 1 , T 2  provide control action for a first half-cycle, and transformers T 3 , T 4 , control the second half-cycle, diodes CR 1 -CR 4  affording this division of control. As the signal from source 10 deviates from zero, a voltage is developed across resistor R 5  connected to summing resistors R 1 , R 2 , and is applied to the bases of transistors Q 1 , Q 2  to render one of the power transistors Q 5 , Q 7  conductive. When a negative signal is produced at resistor R 6  by summing resistors R 3 , R 4 , transistor Q 4  conducts and transistor Q 6  is driven to connect power to the motor during the second halfcycle for a set period. Diodes CR 5 -R 8  are poled to permit the desired current-flow.

Heading C1A. Alkalimetal and ammonium phosphates are extracted, in a proportion greater than 90% of the phosphoric acid present, from impure solutions resulting from sulphuric acid attack on natural rocks, by treating these solutions with a substantially water-immiscible organic solvent in a first series of countercurrent extraction apparatuses, adding a strong acid at one or several stages, then washing -and partially extracting with water in a second series, and with aqueous solutions of phosphate and alkali metal or ammonium ions in a third series, the water from the second series being recycled to the first series as part of the impure feed and the solvent issuing from the third series being at least partially purified and recycled to the first series. Solutions depleted in phosphoric acid, but containing the added strong acid, are collected from the first series of apparatuses, and a pure concentrated soltuion of phosphates is collected from the third series. The preferred organic solvents are tributyl phosphate and triisobutyl phosphate. Formation of emulsions may be avoided by alkaline and acid washing of the solvent issuing from the second series, and by ensuring that the final washing solution is acid.
