Each storage cell 69, 72 may comprise a bi-stable circuit or a shift register, Figs. 8, 9 (not shown), for example the fast access section may comprise an array of bi-stables or 4-bit shift-registers while the slow access section comprises much longer shift registers. In a typical I-M byte storage system there are 64 modules plus further modules for identification; control and error detection/correction purposes, each module being as shown in Fig. 10 and comprising a 16 Î 8 array of chips 35 (addressed by bits C0- C5), each chip comprising a 16 x 64 array of storage cells (addressed by bits b0-b3 and W0-W5). Thus the 16 high speed cells in each chip 35 provide 16K bytes of high speed storage and by selecting one cell from each chip 35 in each module, a "page" containing 1-K bytes can be transferred between the high speed buffer 56 and the low speed backing store 55. The backing store may be considered as storing 128 books each of eight 1-K byte pages. The high speed buffer may then be notionally divided into eight pairs of page sections, the sections in each pair storing corresponding pages from different books. A directory is maintained in one of the additional storage modules to control data transfer between the backing store and buffer and a suitable replacement algorithm is used to insert a page from the backing store into the buffer if the data requested is not in the buffer. The individual cells may be of the type which require periodical regeneration.

Abstract: 1338381 Pneumatic conveyers DIALLED DESPATCHES Ltd 6 Jan 1971 [18 Nov 1969] 56417/69 Heading B8A A pneumatic conveyer system comprises a main tube 1 with a plurality of branch lines 3 each with a receiving and a dispatch station, each branch line having a diverter switch 5, 6 associated therewith and controlled from a central memory. As each carrier is dispatched from a station, its destination is fed by an operator, to said central memory and as the carrier progresses from one zone to the next zone 21, 22 around the system its address is transferred from that part of the memory for the zone the carrier is leaving to that part of the memory the carrier is entering. When the address of a carrier agrees with the address of a receiving station in the zone a carrier is entering, a switch 7 is actuated whereby on passage of the carrier there past it acts to operate the respective divider switch to discharge the carrier to the receiving station. A switch 16 in the branch line is engaged by the discharged carrier to return the diverter switch to its original position. If a carrier is due for dispatch from the said station the switch 16 is overridden and the air deflected into the branch line by the switch 5 acts to feed the carrier into the main tube whereupon a switch 8 is engaged to return the deflector switch 5, 6 to their original position. Control circuits are described to prevent dispatch of carrrier from a station if there is a carrier present in adjacent zones of the main tube and should the situation arise wherein two carriers are present in the same zone, then provision is made to reject the leading carrier.

Filed: 1969-11-20
Abstract: 1,248,648. Milking machines. ALFA-LAVAL A.B. 20 Nov., 1969 [20 Nov., 1968], No. 56839/69. Heading AIM.  A milking machine is provided with a flowrate sensing device 15 in a pipeline between the teat cup liners of the rear cups 12 and a milk receiver 3 held under partial vacuum such that the device 15 operates a control means for varying the degree of vacuum between a working high vacuum and an idling low vacuum. Vacuum lines 1 and 2 having different pressures (250 mms Hg and 550 mms Hg as given) are connected through hose pincher means 38 and- 39 to the milk receiver and through pulsators 43 and 44 of differing frequency to the teat cups 12. When no milk flows through the device 15 the control valve 19, having one connection 21 to vacuum and another 20 to the atmosphere, causes pistons 28 and 29 to operate the pincher means 38-41 such that the milk receiver and teat cup liners are connected to the lower vacuum 550 mms Hg and the pulsator of lower frequency is connected to the teat cups, while during a flow of milk, impulses from the milk sensing device 15 transmitted pneumatically to the control valve 19 cause the pistons 28 and 29 to move to change the positions of pincher means 38-41 thereby connecting the higher vacuum to the milk receiver and the faster pulsator to the teat cups. Instead of pulsators 43 and 44 there can be used one pulsator 45 (dashed lines) of the type whose frequency depends upon the degree of vacuum and instead of pneumatic transmission of the impulses from sensing device 15, hydraulic or electric impulses can be used. In a further arrangement one vacuum pipeline is used having a reduction valve 46 (not shown) such that the milk receiver can be connected to vacuum either directly or through the reduction valve in dependence on the milk flow rate.

These first and intermediate storage devices enables a screen forme on a continuously rotating cylinder to be produced continuously without the preparation of mounting on a scanning cylinder of masters of the required dimensions and in the desired layout plan. The masters are photoelectrically scanned and the resulting analoque values quantized, binary coded and stored as screen dot data relating to complete image lines. Identification data is also produced for each character or picture to be reproduced and stored therewith in the first storage devices. Upon reproduction on to the printing cylinder the data for the page lines of the pages (e.g. three) in a run (e.g. three runs, thus nine pages are reproduced on the cylinder by three engraving units of exposing lamps) and which correspond to a circumferential line of the printing cylinder is successively called up from the intermediate storage device of devices. The same sequence of operations occurs simultaneously for all the runs on the cylinder and is repeated on each revolution of the cylinder. The first storage devices may comprise core stores or drums stores for character data, which data has eight values of density and is stored using threefigure binary numbers, and magnetic tape or disc stores for half-tone picture data which data for example is coded into 64 or 128 graduations. The identification data comprises address and control data. The intermediate storage devices preferably comprise magnetic disc or tape stores.
