Title: Multiprocessing complexes
IPC: G06F12/10
Filed: 1974-10-29
Abstract: 1452843 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 29 Oct 1974 [26 Dec 1973] 46685/74 Heading G4A In a multiprocessing system, each processor includes AAB registers 10-40 holding the main store page frame address or addresses relevant to the instruction in course of execution in order to maintain addressability of the page frame or frames until completion of the instruction execution even though a page invalidation interrupt has been initiated in respect of that (or those) page frame or frames by another processor. The AAB registers are arranged in pairs 10, 20 and 30, 40 to allow crossing of page frame boundaries by individual operands. When a virtual address VA has been loaded into a register 100, the low order page address bit P L  is used to select the even or odd register 10, 30 or 20, 40 of a pair and virtual to real address translation is performed by a unit DATM using segment and page tables ST, PT, the translated page frame address PF being loaded into the selected register 10-40 and, together with the real part D of the virtual address, into a storage address register 110. The AAB registers are not used for non-operand storage access, e.g. for instruction fetch operations. Throughout the remainder of an instruction execution cycle, storage accesses are made via the AAB registers and the segment and page tables ST, PT and translation look aside table TLB are not referred to. When a processor initiates invalidation of a page frame it purges its own TLB so that it can no longer be referred to, sets a co-ordination count field CCF in main store to N-1, where N is the number of processors, and transmits the invalidated PT entry and an interrupt request to all other processors, the interrupts only being sensed after the respective current instruction execution cycles have been completed. Each processor handles the interrupt by attempting to decrement the CCF, the attempt being temporarily blocked if another processor is in the course of decrementing the CCF. The last processor to complete its current instruction execution finds CCF=0 and this processor is assigned the task of transferring an invalidated page frame to an I/O device if a change bit in the key for the relevant storage block indicates that the page has been modified. Each processor, after handling the interrupt, returns to its interrupted programme, and if a processor requires the moved-out page it can be obtained by a page demand interrupt procedure which places the page in another allocated page frame. Since the PT entry and TLB in a processor may be invalidated at any time during instruction execution, the arrangement outlined above ensures predictable results from execution of instructions during which PF invalidation occurs and avoids the need to suppress and repeat execution of any instruction because of the invalidation.

Abstract: 1,217,226. Crimped yams. KLINGER MFG. CO. Ltd. 7 Oct., 1968 [9 Oct., 1967], No. 47444/68. Headings D1F and D1W. A method of producing multifilament yarn composed at least partially of thermoplastics material comprises heating a least two thermoplastic yarns differently to produce differing latent crimp development characteristics, simultaneously crimping the yarns in a stuffer box, combining the yarns and then further treating the combined yarn to develop the differing latent crimp development characteristics. In developing the crimp, the filaments of lesser crimp development lie generally toward the outside of the yarn. Apparatus for producing the yarn comprises a heated godet 17 around which the two ends of yarn Y1, Y2 are wound a different number of turns respectively, a further godet 19 which may be heated and which is driven at a faster speed than the godet 17 to draw the yarns, a stuffer box crimper 33 and means for combining the two yarns. The means for combining the yarns may be a fluid interlacer or twisting means. The yarn Y2 which passes a greater number of turns around the godet 17 is heated to a higher temperature than the yarn Y1 and on subsequent crimping has a higher crimp memory. The yarn may be used for the tufts of pile carpets so that on subsequent development of crimp, e.g. by dyeing, the tufts assume a random configuration due to the crimp.

Abstract: 1494993 Conveying apparatus in a sintering machine STEIRONEL Ltd 13 Jan 1975 [20 Oct 1973] 48962/73 Heading F4B [Also in Division B8] A sintering machine comprises pallets 4 which are coupled together by chains (not shown). The pallets pass around an endless track having superposed upper and lower straight runs and fixed feed and discharge curved end portions therebetween. The track comprises pairs of rails. The pallets are driven at the feed end of the machine by a sprocket 5. The total length of the endless track is greater than the length of abutted pallets to allow for expansion thereof. Thus expansion gaps occur between the pallets on the track, the chains joining the pallets being long enough to allow for such expansion. To ensure that these expansion gaps occur at the lower track run near the drive sprocket and not in the upper track run, restraint is applied to a sprocket 9 which is at the discharge end of the machine and is similar to the sprocket 5. To apply the restraint the sprocket 9 drives a D.C. generator (12), drawing 3 (not shown), having variable resistors across its output. The arrangement is such that a null point (a point at which there are no driving forces acting on the pallets) occurs in the lower run of the endless track so that the coupling chains are in tension only between the null point and the driving sprocket 5. The chains between pallets may be connected to wheel stubs (16), drawing 4 (not shown), by collars (13). The sintering is performed at the upper run of the track. Below this run of the track are wind boxes (6), drawings 1 and 2 (not shown), for sucking air during sintering. In a modification, the means for restraining the movement of the pallets from the upper run to the lower run of the endless track are provided at least in part by the tractive resistance to movement of the pallets (i.e. the friction between the pallets and the track) along the lower run.
