Title: Improvements in data transfer apparatus
Inventor: IRWIN JOHN WILLIAM
IPC: G11B20/16
Filed: 1971-04-19
Abstract: 1282393 Digital data transfer INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [5 March 1970] 22478/71 Heading G4C A digital electric data transfer apparatus in which a byte of data comprises a number of bits transferred in parallel, comprises a deskewing means 12 for assembling bytes, a byte assembly counter 15 for counting the number of bytes assembled, a byte output counter 16 for counting the number of bytes transferred, and means for initiating transfer when the counter 15 holds a greater count than counter 16. Apparatus.-Data is stored on magnetic tape 10 or other means, transferred to the deskewing means 12 (SKB) and thence to a data channel 17. The SKB is a modification of the SKB in British Patent No. 902,164 and has a plurality of read in counters 13 (RIC), one for each bit of a data byte being transferred. The byte assembly counter 15 (BAC) is responsive to the RIC and counts the number of assembled bytes, and the byte output counter 16 (BOC) counts the number of bytes transferred from the SKB to channel 17 via buffer 18. A clock 20 controls operations. Operation.-Every time channel 17 is ready to receive data and compare circuit 22 indicates that the BOC count is less than the BAC count (i.e. there is a byte ready for transfer) the clock 20 is activated. Firstly buffer 18 is cleared then a byte is transferred from the SKB to the buffer. The byte is the oldest in the SKB and is determined by the tally in BOC 16. BOC 16 is then incremented and line 31 activated to determine if BAC 15 is zero. Skew check (Fig. 2, not shown).-Circuit 40 receives the counts from the respective RIC's and, if there is too great a difference between the tallies, there is excessive skew. Overrun check.-Circuit 41 indicates overrun (i.e. more bytes entering the apparatus than leaving so that it is overfull) when the BOC has a predetermined relationship with the leading RIC. The overrun and skew checks do not take part simultaneously and if overrun or excessive skew is detected a diagnostic routine is entered.
Patent GB-663089-A (GB)
Title: Improvements in or relating to the production of diethylketone
Filed: 1948-08-26
Abstract: Diethylketone is made by reacting ethylene, carbon monoxide and hydrogen in the gaseous phase at 100-300 DEG  F. and 100-1500 p.s.i. in a reaction zone containing as a catalyst iron, cobalt or nickel or a mixture of two or more of these metals, the mol. ratios of ethylene to carbon monoxide and to hydrogen being at least 1.5 and 0.67 respectively.  Optimum conversion is obtained using 2 to 4 mols. of ethylene per mol. of carbon monoxide and 1 to 4 mols. of ethylene per mol. of hydrogen.  Preferred pressures are 200-700 p.s.i., optimum results being obtained at 500 p.s.i. when a diluent, e.g. methane, ethane, propane or nitrogen, is present, and 300 p.s.i. when diluents are absent.  Preferred temperatures are 125-225 DEG  F.  Cobalt is the preferred catalyst and catalyst supports and/or promoters may be used.  Advantageously when cobalt is used it is reduced at 450-750 DEG  F., preferably 500-600 DEG  F., with an optimum at 660 DEG  F., the reduction comprising treatment of the oxide or carbonate with hydrogen.  Any form of catalyst technique may be used, e.g. fixed or fluid beds.  With fixed beds space velocities of 50-150 are specified with an optimum at about 100.  Illustrations and examples are provided of the use of fixed bed reduced cobalt catalysts on uncalcined diatomaceous earth containing magnesia and thoria promoters, small quantities of propionaldehyde being obtained with the diethylketone.ALSO:In the preparation of diethyl-ketone from carbon monoxide, hydrogen and ethylene in the presence of a catalyst containing iron, cobalt or nickel or mixtures thereof it is advantageous to reduce the catalyst within the range 450-750 DEG F. preferably 500-660 DEG F. before reaction.  The optimum temperature is 660 DEG F. Thus the catalyst as its oxide or carbonate may be treated with hydrogen for about 24 hours at a space velocity of about 100 within the defined temperature range.  Any catalytic technique, fixed or fluid, may be adopted and conventional supports and promoters used.  Uncalcined diatomaceous earth and silicon-stabilised alumina are typical supports and promoters specified are the oxides of Mg, Th, V, Ti, Zr, Mn and Ca.  In an illustration a catalyst containing 32 pts. Co, 3 pts. Mg, 1 pt. Th and 64 pts. uncalcined diatomaceous earth is prepared from a solution of the metallic nitrates by precipitating with sodium carbonate, filtering, washing, drying, pelleting and treating with hydrogen as described above at 660 DEG F.
