Title: Data processing apparatus
IPC: G06F9/46
Filed: 1968-12-09
Abstract: 1,209,970. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 9 Dec., 1968 [15 Jan., 1968], No. 58363/68. Heading G4A. . In data processing apparatus, each operand word has a data flag field capable of indicating one of a plurality of different programmes and which is decoded to control the progress of the current programme. In a first multi-processor embodiment using a 2-bit flag in each operand word, a processor decodes the flag field of the operand word fetched from an address (in a common memory) specified by its current instruction. If the flag is 00; execution of the instruction proceeds. If it is 01, the first flag bit is changed to 1, the first flag bit of another operand word is changed to 0, and the instruction proceeds. The " other" operand word referred to is that at an address obtained from the address of the current operand word by subtracting the contents of an index register. If the flag of the current operand word is 11, the programme waits until the flag is changed by another programme. The processor occupied by the waiting programme is released, possibly after a predetermined time, for use by another programme. Thus in a matrix calculation, for example, in which an array of operand words is divided up into sub-arrays each representing a row of the matrix and no more than one processor may work on a given row at a time, the first word in each sub-array has a flag of 01, the other words having flags 00, so when a processor finishes with one sub-array, it responds to the flag 01 of the first word of the next sub-array to set it to 11 to prevent another programme using this sub-array and sets the flag of the first word of the previous sub-array to 01 to permit it to be used, the index register holding the difference in the addresses of the first words of two consecutive sub-arrays. A second embodiment uses a 3-bit flag in each operand word, flags 000, 111 acting like flags 00, 11 respectively in the first embodiment. The other flag values cause the address of the current instruction to be saved, and operation to branch to a subroutine, the address of the first instruction of which is contained at an address obtained by adding the flag to the contents of a flag interrupt base register. When the sub-routine has been executed, operation returns to the interrupted programme at the saved address, this programme then proceeding.

Abstract: 1300660 Centrifugal pumps NIKKISO CO Ltd 14 Dec 1970 [6 Aug 1970] 59337/70 Heading F1C A motor-driven pump comprises an impeller mounted on a shaft 14 having a pair of main thrust bearings 22, 24 and co-operating thurst plates 18, 20, and also incorporates hydraulic thrust balancing means defining with the impeller at least one fixed orifice 34, variable orifice 36 and pressure chamber 40. Moreover, one of the side walls defining the variable orifice is constituted by a releasably-mounted auxiliary thrust bearing 38. The bearings are of a material which wears smoothly, e.g. graphite, plastics, ceramic or copper alloy, so that if the variable orifice gap becomes excessive, then the consequent wear at bearing 22 will have a corrective effect. Conversely, if the gap becomes closed then corrective wear occurs at bearings 24, 38. In other embodiments, the auxiliary thrust bearing is attached by a metal clamping ring, functions additionally as a journal bearing for the shaft, is carried by the impeller, is fixed to the wall of the pump housing adjacent the suction inlet, or co-operates with a special thrust ring provided on the impeller. Hydraulic thrust balancing means with respective auxiliary thrust bearings may be arranged at both sides of the impeller. Thrust plates 18, 20 may be subjected, during manufacture, to surface treatment such as metal plating or grinding to facilitate the smooth wear. All bearings are replaceable.

Title: Control of the concentration of dissolved solids in evaporator  systems

Filed: 1970-12-17
Abstract: 1368067 Blowdown apparatus for boiler NALFLOC Ltd 3 Dec 1971 [17 Dec 1970] 60072/70 Heading F4A [Also in Division B1] An automatic blow down apparatus is used to control the concentration of dissolved solids in boiler water. The water is blown down for a predetermined duration at predetermined intervals until a means, which peri odically samples the boiler water, detects a concentration of dissolved solids above a predetermined level; the frequency of blowdown and/or the duration of each discharge is then increased until the concentration has fallen below a second predetermined level, when the original blowdown rate is resumed. In the embodiment shown a boiler 1 has water inlet 2, steam outlet 3, manual blowdown line 4 and automatic blow down line 7. An automatic blowdown valve 9 is controlled by a timing means to periodically discharge line 7 via line 10 to drain line 6, and a valve 22 is controlled to allow a sample of blown down water to pass via condenser 21, to a conductivity cell 23 at a frequency probably the same or lower than the blow down frequency. The conductivity measured by cell 23 is proportional to the concentration of dissolved solids and when the concentration is detected above a first level the cell 23 acts through a relay to short out a duration timer which normally imposes a short discharge time on each blowdown. Cam mechanisms, driven by a common motor, are employed to control the frequencies of blowdown and sampling, and the mechanism for blowdown, in the absence of the duration timer, allows a longer discharge duration. When the concentration has fallen below a second level, which may or may not be coincident with the first, the duration timer is cut back in and the original blowdown rate is resumed.
