Title: Process for the manufacture of new depolymerisation products from carbohydrates of high molecular weight
IPC: C08B37/00
Filed: 1927-02-15
Abstract: 290,377. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). Feb. 15, 1927 Starch depolymerization products.-Starch is depolymerized or degraded by heating with ethylene glycol or monochlorhydrin or mixtures thereof. The heating is conveniently carried out in reflux apparatus. The starch readily dissolves, giving products which are soluble in alcohol and water, which no longer exert a reducing action and do not give the iodine coloration, and which on hydrolysis with acids yield sugar. The glycol &c. is removed by distillation in vacuo or at comparatively low temperatures. In examples, starch is boiled with ethylene glycol, the latter eventually distilled off in vacuo leaving a syrup which possesses a sweet taste; starch is first boiled with ethylene glycol, and boiling continued after the addition of monochlorhydrin.

Title: Computer system
IPC: G06F9/30
Filed: 1966-02-01
Abstract: 1,093,499. Digital electric computer. RADIO CORPORATION OF AMERICA. Feb. 1, 1966 [Feb. 15, 1965], No. 4385/66. Heading C4A. A digital electric computer having a random access memory and a staticizing register, has a number of instruction execution units each capable of executing solely the individual instructions classified in one of a group of similar instructions, and an operation group decoder to determine the group to which a staticized instruction belongs and to enable a respective one of said instruction execution units to receive the staticized instruction and to execute the instruction. As described (Fig. 1, not shown) seven bit words are taken from memory as addressed by a programme counter and entered into an instruction register. The instruction register holds a four word A address, a four word B address, a one word Operation Code and a one word character operation option. The Operation Code word is applied to a decoder which enables the appropriate execution unit. An execution unit for performing the operations AND, OR, EXCLUSIVE OR and COMPARE is shown in Fig. 4. If any of these operations are to be performed line G2 is enabled and the instruction word fed via AND gate 22 into an instruction register in the unit. The Operation Code is decoded and a signal defining the operation is applied to a matrix arrangement, Fig. 5, whch acts to perform the operations. A counter is connected to appropriate points on the matrix, the horizontal lines of which act as AND gates so that a line will not be enabled unless all inputs connected to it are present. For an AND operation the Operation Decoder, Fig. 4, sends an AND signal. This enables the first seven lines of the matrix. The counter is set on 0 so a line SET F A  is enabled to set flip-flop F A , Fig. 5. This enables a flipflop 24<SP>1</SP> to send the A<SP>1</SP> Address to a Memory Address Register (Fig. 1, not shown). The word in the specified address is read out and passed via gate 27<SP>1</SP> to be stored in part A of the instruction register. At the same time a marker flipflop DPA is set. A new line of the matrix is now enabled which Resets F A  and DPA and sets F B . This allows the B<SP>1</SP> Address to be supplied to the memory, and a second word read out to part B of the register. F B  is then reset as in DPB, Do is set and the count is increased to 1. This enables the A and B data to be supplied to the logic unit 42 and the result applied to register A which sets DPA. Do is then Reset and SA Set to transfer the result to Memory. Registers A<SP>1</SP> and B<SP>1</SP> are then incremented by 1 and N<SP>1</SP> is decremented. N<SP>1</SP> allows the procedure to be repeated as long as N<SP>1</SP>> 0. A similar system described for the grouped operations Locate Symbol Left, Locate Symbol Right, Transfer Data Left, Transfer Data Right allow data words to be shifted in the memory.

Abstract: 391,935. Step-bystep conveyers. PORTER, W. J. H., 122, Queen Street, Cardiff. Feb. 15, 1932, Nos. 4445 and 18105. [Class 78 (i).] Relates to a reciprocating conveyer with pivoted scrapers for moving furnace ash along a trough into which the ash is delivered through a water-sealed shoot. The construction permits of the conveyer working past the end of the shoot, and the scrapers are pivoted independently so that any scraper which jams may be readily released. The apparatus comprises a reciprocating frame 4 above the trough 2, U-shaped bars 5 connecting the side members of the frame, and scrapers consisting of side members 7 pivoted to the frame 4 at 8 and connected at their lower ends by blades 6, the members 7 resting against the bars 5 and extending upwardly as at 9 for engagement with rollers 19 on actuating bars 17. The bars 17 are carried by parallel links 18 pivoted on the frame 4 and are moved relatively to the frame by the engagement of levers 20 with ramps 24. In operation the frame 4 is moved to and fro by a crosshead 13. In moving to the right, the scrapers are held in the position shown by the bars 5 and push the ash along the trough. On the return stroke the rollers 23 on the levers 20 ride up the ramps 24 so that the bars 17 move further to the left and raise the scrapers. On the next stroke to the right the rollers 23 pass beneath the ramps 24 which are pivoted at 25, and the scrapers are free to take up their original position. The weight of the ramps ensures resetting of the bars 17. The ends 9 of the scraper members may be weighted to facilitate tilting. The bars 5 serve to level the ash in the trough. The frame 4 is supported and guided by wheels 10 running on rails along the trough and by rollers 12 or runners engaging beneath a flange on the trough. The conveyer may follow a broken, curved, or inclined path. The ash shoot may be provided with a crushing roller.
