Title: Memory access control in data processing systems
IPC: G06F9/28
Filed: 1975-09-12
Abstract: 1493448 Accessing data stores FUJITSU Ltd 12 Sept 1975 [12 Sept 1974] 37682/75 Heading G4A In a data storage system including a plurality of memory banks (in the embodiment of Fig. 2 there being two banks 1-0, 1-1), cycle designation means 9 designates the banks in succession in successive access cycles, a detector 7 detecting for each cycle non-coincidence between the designated bank and the bank specified by address data supplied for the cycle, any data access being invalidated in the event of non- coincidence. As described, for two banks the cycle designation is a latch but if more banks are included it is replaced by a counter. Micro-instructions read out from the banks (control stores) to a register 4 may be of two types, type 1 having a portion NA 0  specifying a module address and a portion NA 1  specifying the address within a module, in each module addresses 0000 to 0111 lying in bank 1-0 and addresses 1000 to 1111 lying in bank 1-1, and type 2 having only a portion NA 1 , the module address being unchanged from the preceding instruction. Generally address portion NA 1  alternates between banks so that microinstructions accessed in cycles t 0 , t 1  ... are read out sequentially in cycle t 2 , t 3  ... to decoder 22 and address assembler 6 which receives its module address from a holding register 5-0 and address part NA 1  from register 4. When however a change of module occurs decoder 22 recognizes a type 1 instruction and enables a gate 23-2 (Fig. 5, not shown) so the module address on bus 16-0 is fed to the address assembler. When the same bank should be accessed twice, for example during a jump routine, the resulting signal from non- coincidence detector 7 results in (1) gates (23-3, 23-6, Fig. 5, not shown) being enabled to cause the contents NA 0  and NA 1  of holding registers 5-0 to be read to address assembler 6 and (2) the setting of a latch 19 so that in the next cycle the accessed erroneous microinstruction is not clocked into register 4.

Title: Apparatus for producing graphical data descriptive of an  integrated circuit design
IPC: G03F1/00
Filed: 1974-08-30
Abstract: 1445914 Integrated circuit design INTERNATIONAL BUSINESS MACHINES CORP 30 Aug 1974 [27 Sept 1973] 37953/74 Heading G4A Apparatus for producing graphical data descriptive of an integrated circuit design includes means for storing graphical description of free form designs, means for storing topological data and electrical characteristics of rules restricted designs, means for entering information for correlating a free form design with a rules restricted design and means for merging the generated graphical description of the rules restricted design with the stored free form design. Initially the designer produces a lay-out in block form of the logical functions to be included in the chip. Next he selects a chip image (as in Fig. 3, not shown) and assigns logic functions to different areas of the chip (by using X, Y co-ordinates). From this, information in the form of the required logic and possible placement of it is fed in to an FET automated design system 16 (Fig. 2), this comprising a series of programs for execution on a general purpose computer. From the input information and information from a library 18 (which is a file describing the electrical characteristics of circircuits, topology thereof and images) the system generates a chip image (38, Fig. 4, not shown). Next the device sizes required for each circuit to meet its specified performance are calculated (42), information relating to (1) the input wave form and/or loading present at input/output pads (44) (in the form given in Fig. 5d, not shown), (2) the connections necessary to implement the logic (48) (in the form given in Fig. 5c, not shown), (3) circuit data information (46) (in the form given in Fig. 5a, not shown) and (4) free from data (50) (in the form given in Fig. 5b, not shown) being fed in. The next step (52) is the calculation of the circuit locations from the output of the previous step (42) and circuit data with relative co-ordinates included (54). From this information a wire list (56) is produced indicating the co-ordinates for each LST from which the designer derives data (of the form given in Fig. 5e, not shown), a wire routing operation being effected using this data and the output of the previous step (52) to interconnect all the circuit LSTs and I/O pads. A check is made on for example critical spacing and net continuity. The output of the system 16 is used to obtain from the library 18 the free form description with which it is merged to form a total chip description (11) from which photographic masks may be made to produce a LSI device.

Patent GB-941567-A (GB)
Title: Hydrolysis of aluminium alkoxides
IPC: B01F27/91
Filed: 1961-10-25
Abstract: Aluminium alkoxides are hydrolysed by contacting the alkoxide with a hydrolyzing agent, with agitation in counter-current flow, in a series of contacting zones, accumulating the alcohol product at one end of the series of zones and the aluminium hydrolysis product (aluminium salts or hydrated alumina) at the other end and recovering primary alcohols and aluminium hydrolysis product. The process may be performed at 25 to 150 DEG C. at atmospheric pressure or above with at least a stoichiometric amount, and usually a 2 to 200% excess based upon the alkoxide, of hydrolysis agent. The alkyl groups of the alkoxides contain from 1 to 30 carbon atoms, specific examples of alkoxides given <PICT:0941567/C2/1> being aluminium-ethoxide, -isopropoxide, -butoxide, -hexoxide, -decoxide, -tetradecoxide, -octadecoxide, and eicosoxide, and the hydrolyzing agents may be water, steam, certain bases, e.g. sodium or potassium hydroxide, or, preferably, mineral acids.  Whilst individual alkoxides may be used it is usual to utilize mixtures of alkoxides and in particular those mixtures obtained by the oxidation, by air at 20 to 50 DEG C. and 10 to 60 p.s.i.g., of aluminium trialkyl growth product obtained by the reaction of aluminium trialkyl with a C2 to C4 mono-1-olefin at 65 to 155 DEG C. and 200 to 2,000 p.s.i.g.  In a preferred embodiment the aluminium alkoxides enter, via conduit 8, a vertical hydrolysis column 2 containing a series of horizontal baffles 4, open in the centre to accommodate the propellers 6 being driven by motor 7, and being surrounded by a cooling jacket 18, in which cooling fluid, e.g. water, circulates from inlet 16 to outlet 20.  The alkoxide flows counter-current to the hydrolysing agent entering via conduit 14, the alkoxide being dispersed in the aqueous phase, and the alcohol product, accumulated in settling zone 11, is withdrawn via conduit 10, whilst the aluminium hydrolysis product, accumulated in settling zone 13, is withdrawn via conduit 12.  In the examples aluminium alkoxides are hydrolysed with sulphuric acid.

A ram 7 extends the section 2 and has its cylinder end pinned near the inner end of section 1 and its rod pinned near the outer end of section 2. A ram 8 for .extending the section 3 is pinned at the inner end of section 2 and at the outer end of section 3 while a ram 9 for extending the section 4 is similarly arranged with respect to sections 3 and 4. A bar 10 at the outer end of section 2 supports the underside of section 3 while a bar 1 similarly supports section 4. The section 3 is provided at its inner end with downwardly extending feet 12 which straddle the ram 7 while riding along the floor of the section 2. The section 4 is similarly provided with feet 13 which slide on the floor of section 3. The rams 7, 8, 9 are extended by fluid pressure from a pump P under the control of flowdivider valves 20, 23 the former of which sends one third of the fluid to the ram 7 and twothirds of the fluid to valve 23 which divides the entering fluid equally between the rams 8, 9 thus ensuring synchronized extension of the jib sections 2, 3, 4. Retraction of the sections 2, 3, 4 is by a cable 14 from an hydraulically driven winch 15, the flow divider valves 20, 23 acting to re-combine the fluid flows to synchronize the retraction of the sections. If the rams 7, 8, 9 become desynchronized due, for example, to leakage then pressure relief valves 31 enable all the rams to be bottomed-out to resynchronize their operation.
