Patent GB-974877-A (GB)
Title: Purification of hecogenin
IPC: C07J75/00
Filed: 1962-11-08
Abstract: Hecogenin is prepared from a crude product obtained from agave leaves by hydrolysis of the heconin contained in the leaves by producing from the crude product a solution of hecogenin in a solvent mixture containing at least one organic polar solvent for hecogenin, at least one organic non-polar non-solvent for hecogenin and a controlled amount of water to induce separation of the solution into two phases and recovering hecogenin from the upper phase. When the moisture content of the crude hecogenin is relatively high, the extraction may be carried out with the solvent and non-solvent direct. A suitable polar solvent is methanol and a suitable non-polar solvent is a saturated or unsaturated aliphatic hydrocarbon which is liquid at room temperature. The above process may be modified in any of the following ways: (a) the crude hecogenin is extracted with the solvent for hecogenin, the resulting extract is mixed with the non-solvent for hecogenin and water in such proportions that two phases are formed, and the upper phase is withdrawn for hecogenin recovery; (b) the crude hecogenin is extracted with a mixture of the solvent and the non-solvent for hecogenin, the resulting extract is mixed with so much water than two phases are formed and the upper phase is withdrawn for hecogenin recovery; (c) the crude hecogenin is extracted with a mixture of the solvent for hecogenin and water, and the resulting aqueous extract is mixed with the non-solvent for hecogenin to form two phases, and hecogenin is recovered from the withdrawn upper phase; and (d) the crude hecogenin is extracted with the mixture of the solvent and non-solvent for hecogenin and water at a temperature at which the said mixture forms a homogenous phase, the extract is cooled to cause phase separation, and the hecogenin is recovered from the withdrawn upper phase.  The latter modified method is suitable for a process carried out in a continuous manner. The hecogenin extracted by the above process may be further purified, for example, by boiling a methanolic solution of the purified hecogenin in the presence of charcoal. Specifications 974,876 and 974,878 are referred to.

Title: Computer with probability means to transfer pages from large memory to fast memory
IPC: G06F12/08
Filed: 1971-09-22
Abstract: 1354800 Data processing systems RCA CORPORATION 22 Sept 1971 [1 Oct 1970] 44155/71 Heading G4A An addressing system is operable to directly address a relatively fast, small random access memory 12 when it is determined that the desired word is located in that memory, and, if the desired word is in a large, relatively slow random access memory 14, to directly address the memory 14, there being a relatively small probability that instead of addressing memory 14, the system transfers a page of words including the desired word from memory 14 to memory 12. The arrangement allows up to 80% of the memory references to be made to fast memory 12. A processor 10 supplies virtual addresses via register 18 to a translator 20 which contains a table for converting the virtual addresses to real or actual addresses. A comparator 30, supplied with an input A representing the dividing line between the locations in memory 12 and those in memory 14, either passes the real address from register 22 via gate 32 to the address register of memory 12 or enables a gate 34 to pass the output of a random number generator 36 to a register 38 if the real address is in memory 14. A comparator 40 is supplied with an input P such that normally a gate 44 is enabled to pass the real address to the address register of memory 14 and only once in several thousand times is the output 43 of comparator 40 energized. The output 43 operates an interrupt generator 24 which initiates transfer of a page of words from memory 14 to memory 12, the particular page being that containing the word identified by the real address passed to register 26. After the transfer, processor 10 modifies the table in translator 20 to reflect the changed real address of the transferred page. A counter 48 and a comparator 50 supplied with an input K may be included to limit the number of pages which may be transferred to memory 12, e.g. to 50 or 60% of the pages in memory 14. The comparators 30, 40, 50 may each be formed by a register and decoder, inputs A, P, K being fixed, or by comparison circuits if the inputs A, P, K are variable by the programmer. Memories 12, 14 may be semi-conductor and core memories respectively.

Abstract: 1,088,359. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Oct. 22, 1965 [Oct. 23, 1964], No. 44761/65. Heading H4K. In an exchange system, having a reed relay switching network and a route simulating network, the guide wires between each node of the latter are threaded through unique combinations of magnetic cores which are so arranged that a route-seeking signal causing saturation in one of them leads to saturation in the opposite sense of the remainder, in the manner of a lock-out circuit. As shown, the simulating network, for a threestage full-availability switching network, consists of a plurality of nodes corresponding to each matrix of the switching network which are linked by diode-decoupled guide wires. The availability of interstage and outlet links is indicated by the condition of contacts b, c and d. Each guide wire is threaded through a set of cores M1 to M8 or M9 to M16 utilizing any coding procedure of binary code may be adopted. In operation, a signal generator JG connects an offering signal via a selected outlet e to the network whereby all free paths are marked. If one or more of the inlets a is in a calling condition, the signal passes to another signal generator J which then selects one of the inlets only and reverts an acceptance signal over the network. In addition J successively triggers transistorized selection circuits St B and St C, which are more fully described in Specification 1,060,525, whereby at each stage that combination of cores through which the acceptance signal is passing and which has the highest priority saturates and locks out the remainder. The identity of the unique path so obtained is determined from the conditions of the cores whereafter the corresponding path through the switching network is set up.

Abstract: 1,187,197. Winding bobbins. ATELIERS ROANNAIS DE CONSTRUCTIONS TEXTILES. 20 Sept., 1968 [21 Sept., 1967], No. 44860/68. Headings DID and D1J. Apparatus for driving the friction roll 3 of a drum winding machine comprises a drive shaft 1 on which the roll 3 is mounted to be rotatable and axially slidable, co-operating toothed annuli 6 of the shew-dog type on the roll and shaft and magnetic means such as a permanent magnet 10 on the shaft and a washer 7 on the roll for maintaining the annuli in contact. The roll can be declutched and linked by a fork comprising fingers 17a, 17b mounted on a square rod 16 slidable parallel to shaft 1. Rod 16 is biassed to the right by a spring 19 but is normally prevented from moving by a pin 21 thereon engaging in a slot in a lever 22 so that in normal operation fingers 17a, 17b have a small clearance from the end surfaces of the roll. Lever 22 is held in position by a linkage mechanism 24, 25, 28 which has a lever latch 24 engaging a notch 30 in a pivoted lever 31. Should a yarn break upstream of the take up package a stop motion causes an electromagnet 34 to be energised thus rotating lever 31 anticlockwise. This allows latch lever 24 to fall and therefore rod 16 to move to the right, the finger 17a engaging the end of the roll and moving the roll to separate the annuli 6 and move the other end of the roll into contact with a braking surface 37. To re-establish drive to the roll a cam 43 is operated by a handle 42c to lift lever 22 thus moving rod 16 to the left and re-engaging the annuli. Simultaneously the latch lever 24 is brought into engagement with notch 30 on lever 31 which has moved to the right under the influence of a spring 33, the electromagnet 34 having been de-energised by the restitution of the yarn upstream of the package.
