Title: Digital data processing systems
IPC: G06F13/12
Filed: 1972-05-02
Abstract: 1391996 Digital data processing systems COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 2 May 1972 [7 May 1971] 20295/72 Heading G4A A micro programmed digital data processing system includes a central store MC and processors, UT, each processor including a zone arranged micro programme control store MD, a zone arranged word processing store HT, each store having an associated zone address register T, J and a read/write register U, V through which a plurality of peripheral devices Po-Pn are connected by coupling units Co-Cn to the read/ write register U of the store MT. To transfer data from, e.g. a magnetic disc in a peripheral unit P i  via processor UT j  to central store MC, an instruction word, indicating the number of words to be transferred and the address at which the words are to be entered, is read from the store MC into processor register M. The data is held in this register until control store MD ends a micro programme when it permits interruption of its current programme and allots a zone Z k  of store MT to the exchange operation, the number of words to be transferred being stored in the allotted zone. The address at which data is to be stored in memory MC is held in a store S. The address of the section of the disc from which data is to be read out is entered into register U, this address being either contained in the instruction word from store MC or on request by the processor. A coupling unit C i  receives the address and decodes it to select the required section of the drum. When a comparator receiving both the address code and the read out address of the drum is triggered it delivers a signal S i . If this has higher priority than the interrupted programme a gate H i  is enabled by the output of priority control circuit CH, the address currently stored in registers T, J being entered into registers GT, GJ. Other data relating to the interrupted programme is held in registers of store MT. Encoder K i  encodes the signal from coupling unit C i  and feeds the addresses corresponding to the exchange micro-programme and the zone Z to registers T, J. The micro-programme is then executed with a word being entered via unit C i  to register U from which it is transferred via register M to the address in store MC determined by the content of register S. Register S is then incremented and the count of the number of words to be transferred decreased, this process being repeated until the count is reduced to zero when an instruction is fed to de-activate the coupling unit. The interrupted programme is then resumed, the appropriate data being recalled by the final instruction of the executed microprogramme.

To lessen friction the arms 41 may be provided with recesses housing balls or rollers to engage the surfaces 27, and in an alternative embodiment an auxiliary inertia disc coupled to the disc 23 may be provided, the increased inertia lessening the effects of friction and thus the dependency of the sensitivity of the reel to its attitude when, installed in a vehicle. To remove this dependency completely in a further described embodiment the auxiliary inertia disc is provided with a control cam which pivots a spring loaded pawl into engagement with teeth on the reel housing to provide positive relative rotation between the disc 23 and shaft 17. A pendulum may also be associated with the reel and arranged such that changes in acceleration of the vehicle will cause a locking pawl to prevent rotation of the inertia disc 23 thus causing a locking the reel as described above.

When a carrier 22 is on the track 14, it is halted by a stop 74 movable to depress only the leading driving dog 70, the pushers clearing the halted dog 76 because of a rise in the track 18. Interlocking blocking devices 78, 80 prevent a carrier from moving off the end of any of the track sections 10, 12, 14 when the track 14 is not aligned with the sections 10, 12.

Abstract: 1352971 Teleprinters SIEMENS AG 19 April 1971 [5 Feb 1970] 20602/71 Heading H4P A teleprinter receiver includes a shift register into which multi-element start/stop character signals are fed and from which a printer is controlled and to avoid false printing at end of a connection the printer is inhibited by a signal generated from the continuous stop signal present on the line at the end of a connection or by a termination, or so-called erase, signal sent by a central switching unit. A 5-bit character signal enters register stages K5-K1 by clock pulses ST, the start signal on reaching KAn opens gate G1 to stop further shifting, transfers the character to print stores A5-A1 and initiates printing via gate U and control AF. At the end of transmission the "32" (no print) signal is present in the register. When KSp is set by the start bit in KAn it provides an S signal to one input of gate G2, the other input being generated by the continuous start signal on the line which resets bi-stable KT. The output of gate G2 resets bi-stable KS to provide a blocking signal DS to print control gate U. In another arrangement logic ZS is removed and a line carrying the termination or erase signal leads via an inverter direct to gate U (Fig. 1, not shown).

An incombustible, foamed siliceous material is made by forming an intimate mixture of 100 parts by weight of an aqueous silica sol containing 10 to 15% w./w. silica and having an initial pH within the range 0.8 to 2.0, 3 to 15 parts by weight of an inorganic compound capable of reacting with the silica sol to release carbon dioxide and 0.4 to 115 parts by weight of a filler. The inorganic compound may be an ammonium, alkali metal or alkaline earth metal carbonate or bicarbonate or an alkaline earth metal basic carbonate. The structure of the foamed material may be controlled by the addition of a silicone-polymer preferably silicone-glycol copolymer or a non-ionic surface-active agent to produce a buoyant foamed material with small uniform pores. An effective filler is fly ash and other suitable fillers include kaolinite clays, fine silica sand, plaster of Paris, perlite or vermiculite, and preferably includes 0.4 to 5 parts by weight of a fibrous product such as asbestos, glass or ceramic material to bind the above mentioned fillers together. A silica sol having a pH of 1.0 to 1.4 is preferably aged for a time depending on its concentration before the formation of the intimate mixture to control the polymerization of the silica and to permit better control of the final foam structure.
