Title: Improvements in the production of ethylenediamine carboxylic acid compounds
IPC: C05D9/02
Filed: 1964-11-26
Abstract: A mixture of ethylene diamine bis (o-hydroxyphenylacetic acid) and ethylene diamine bis (o-hydroxyphenylacetic acid)- monoamide is obtained by hydrolysing ethylenediamine bis (o-hydroxy-phenylacetonitrile) with hydrochloric acid with a concentration greater than 40%. The starting nitrile may be obtained by reacting one mole of ethylenediamine with two moles of salicylaldehyde to give the corresponding Schiff base which is then reacted with 2 moles of hydrogen cyanide.  Hydrochloric acid of the required concentration may be obtained by mixing concentrated hydrochloric acid with anhydrous hydrogen chloride or concentrated sulphuric acid.

Filed: 1975-12-01
Abstract: 1505580 Address translation FUJITSU Ltd 1 Dec 1975 [30 Nov 1974] 49305/75 Heading G4A An address translation system for converting logical addresses representing the page and line of a program to a physical address representing the location of the addressed item in main memory comprises a first (page map) address converter 7 (Fig. 2) and a second (page table) address converter 8, the second converter only being used for pages which are shared between two or more programs. The system also includes an associative memory 6 in which the logical addresses of the most frequently used items are stored with their real page address, at comparison between the logical address of a desired item held in register 5 and a stored logical address the real page address being read out to register 12 where it is combined with the line number (from register 5) to derive the address to access the main memory. If it is not in the associative memory (or if the data is invalid, represented by a "0" bit in Section A) map pointer registers 14 are accessed, one being selected by section PN of the logical address to read out an address designation which is used in conjunction with the page number LPN 0 to address page maps 16 in the main store to read out the physical page address RPA, validity data A and control data X, Y. The data Y indicates whether the information is in the main  store or whether transfer from an auxiliary memory is necessary. The data X when set to "1" indicates that the page is shared with another program and that the page table converter 8 must be accessed using the address read out from the page map 16 to index an address in a table pointer register 24 holding the address of the page table 26. The address RPA read from the table is combined with the line number of the logical address to derive the complete physical address. Consequently when the physical addresses of pages shared between several programs are changed only the table 26 has to be altered.

Abstract: 1,119,420. Centrifugal separators. M. CHRIST [trading as FIRMA MARTIN CHRIST FABRIK ELEKTRO - MEDIZINISCHER - APPARATE]. 25 Nov., 1965 [25 Nov., 1964], No. 50115/65. Heading B2P. In an ultracentrifuge for analysing liquid substances by sedimentation in a liquid having a density gradient and contained in centrifuging vessels which are swung into a horizontal position during operation, mixing of the liquid layers of different densities is prevented by imparting a relatively slow acceleration to the driving motor upon starting and until the vessels have attained a horizontal position whereupon the motor is accelerated to full speed. In Fig. 1, only one centrifuging vessel 6 is shown pivotally attached at 5 to the edge of a disc 8 carried by a shaft 4 driven by an electric motor M. A resistor R is mounted in series between the motor and a single phase or d.c. supply and is shunted by a switch S which is opened and closed by a timing device Z. At the start of an operation, the switch S is open until the motor has slowly gathered speed and the vessel 6 haas reached the horizontal position 6". The switch is then closed and the motor attains its maximum speed. The interior of the housing enclosing the disc 8 and vessel 6 may be evacuated. In a modification, Fig. 2, the motor M is coupled by way of a centrifugal friction of magnetic coupling K to a transmission G which operates the movable arm A of a rheostat P in series with the motor in accordance with the motor speed, the coupling causing separation of the transmission from, the motor when the latter attains a predetermined speed corresponding to the horizontal position of the vessels. Alternatively, the rheostat is controlled by means of a revolution indicator mounted on the centrifuge.

Apparatus for feeding sheets 1 and aligning them laterally before they enter a processing machine, comprises two endless conveyer belts 10, 11 arranged one above the other to grip and feed the sheets past a photo-electric sensing means 22, 23, the pulleys 12 . . . 16 supporting the belts being mounted in a frame which has slides 18, 19 engaging in recesses in the main frame 20, 21, and means is provided for shifting the belts transversely under the control of the sensing means 22, 23. As described, the sheets 1 are fed sequentially to a suction drum 5, and are placed between the belts 10, 11 by a suction drum 3. If two superposed sheets are received by the drum 5, a roller (4, not shown) cooperating therewith is urged away from the drum to operate a switch and cause suction to be maintained on the drum 5 so that the sheet is not released to the drum 3, but is released later and discharged through a shoot. The sensing means comprises two photo-electric means 22, 23 adjustably spaced apart so that their beams are not cut off by a correctly aligned sheet: a displaced sheet cuts the beam of one or the other means 22, 23, and causes an appropriate transverse movement of the belt system. A second photo-electric means 24, 25 and, where necessary, as succession of such means may be provided along the sheet path L, the space a between such means being equal to or less than the width of the sheets. The aligned sheets are further conveyed by opposed belts 26, 27 between a pair of belts of the processing machine, assisted by an endless chain having abutments thereon and arranged between the belts. The abutments travel at a speed which is slower than that of the belts 26, 27, so that the sheets are urged by the belts against the abutments.
