Abstract: 1,230,052. Magnetic disc stores. NATIONAL CASH REGISTER CO. 7 Jan., 1970 [31 Jan., 1969], No. 792/70. Heading G5R. The magnetic surface of a rotary disc interchangeably mounted on a spindle carries a non- magnetic calibration pattern which causes a radially-adjustably reading head to produce signals which indicate when it is passing over a particular track. As described, the pattern consists of sets of holes of various sizes and radial distances (Fig. 4) etched through the magnetic surface to the non-magnetic substrate. The disc is rotated and the head unit is adjusted radially until the signal pattern seen on an oscilloscope conforms to that required.

Abstract: 1,232,282. Composite filaments. SMITH & NEPHEW RESEARCH Ltd. 27 Aug., 1969 [27 May, 1968], No. 25287/68. Heading B5B. A filament formed by extruding a mixture of polymers, comprises a plurality of radially successive and axially disposed generally arcuate layers. The filament may be formed by mixing polymers in particulate form, for example highdensity polyethylene and polypropylene; heating the heterogeneous mixture to a temperature high enough to melt both polymers, and extruding the mixture by ram extrusion through an orifice or die. The preferred ratio of polyethylene to polypropylene in the mixture is in the range of from 20: 80 by weight to 80: 20 by weight, desirably 20: 80. The filament is suitably quenched in water which is at a temperature between 0‹ and 40‹ C., and then colddrawn out under tension; this has a tendency to produce a central void in the filament. This can also be produced by using a higher extrusion rate followed by drawing. In the drawn filament the layers tend to separate, the spaces between the layers being periodically bridged by fibrils. The orifice used in extruding the mixture preferably has a diameter between 2 mm. and “ inch (6À35 mm.), and the die has a length preferably between 5 mm. and 100 mm., such that the polymer material undergoes laminar flow when extruded through it.

Abstract: 1,257,525. Thermal storage; central heating systems; liquid heaters. ELECTRICITY SUPPLY BOARD and W. J. CAMPBELL. 13 Feb., 1969 [14 Feb., 1968], No. 7861/69. Headings F4A and F4U. A central heating system receives its heat from a liquid thermal storage reservoir provided with a liquid circulation system for maintaining a desired temperature at the output point of the reservoir. As illustrated, the central heating system includes a pump 18 and an atmospheric connection 16, and draws its heat from a heat exchanger 15 located near the bottom of a water reservoir 11 which is heated by a heating element 12. A pump 14 is under the control of a thermostat 21 and, by returning water from the bottom of the reservoir to higher points, causes a downward migration of hot water in the reservoir to maintain a required temperature at the exchanger 15. Part of the water from the pump 14 is returned through a sparge pipe 24 which includes a thermostatic valve 25. The heating element is controlled by a thermostat 22 which is overridden by a pressure limiting switch 23. All but the lower part of the reservoir 11 is provided with thermal insulation 26. Omission of the insulation from the bottom of the reservoir ensures that, under static conditions, the temperature of the heat exchanger 15 does not rise to an excessive level. In a modification, Fig. 2 (not shown), the single reservoir is replaced by an upper and a lower reservoir connected by a pipe, the lower reservoir containing the sparge pipe and the heat exchanger. In another embodiment, Fig. 3 (not shown), water moving from the reservoir to the feedback pump passes through a heat exchanger which is located in a tank forming part of the central heating system.

Abstract: 1,266,579. Digital data storage. INTERNATIONAL COMPUTERS Ltd. 21 Aug., 1970 [26 Aug., 1969], No. 42337/69. Heading G4C. A digitaldata storage system comprises a bulk store 1 and an associative memory 9 holding address information relating to the store so that a request for data in the store is dealt with by interrogating the addresses in memory 9. The bulk store may be magnetic discs, a drum or a core matrix, and in the former case each disc has a plurality of data tracks, each divided into addressable sectors. To record data, a central processor 3 sends the data to an intermediate store 2 (e.g. core matrix, thin film or semi-conductor) and its address to selector 5 which positions the write heads and records the data from store 2. The position of a data item in store 1 may be specified by the first and last sector addresses which it covers by a relative address or by chain addressing, and this address information is simultaneously sent to associative memory 9 with item identification data. To access a data item, the item identification data is fed from processor 3 to memory 9 and compared in parallel with the data therein, corresponding data being marked. The marked entries are read out in turn to test unit 12, which also receives the identification data, and the particular address in the disc is calculated whence unit 5 accesses the requested data. The test unit (Fig. 2, not shown) may add or subtract &c. depending on the address notation used. The memory 9 may be accessed by several processors in a multiplex mode.
