Title: Data storage apparatus
IPC: G11C11/408
Filed: 1973-05-14
Abstract: 1427156 Data store INTERNATIONAL BUSINESS MACHINES CORP 14 May 1973 [30 June 1972] 22759/73 Heading G4C A data store includes drive lines 48-54 each associated with a respective group of storage cells 90-98, driver circuits 56-62 for selectively applying drive pulses to the lines, and switching circuits 68-74 for responding to drive pulses on the lines to disconnect the lines from a source of reference potential, e.g. ground. A restore pulse at 80 charges node E to turn on FET's A in the latches 68-74 to ground all the word lines 48-54. An address pulse, coinciding with the termination of the address pulse, enables FET's 56-62 and a drive pulse is applied to a selected one of the drive lines, say 48, via the corresponding FET 56 to turn on transistor B in the corresponding latch 68 and discharge node E, the non-selected drive lines 50-54 being grounded via the corresponding transistors 58-62. The discharging of node E turns off the transistors A in the remaining latches 70-74 so that all the drive lines are disconnected from ground. However all the the drive lines except the selected one 48, which is charged by the drive pulse, are grounded via their transistors 58-62. A selected cell associated with the charged drive line may then be accessed for a read or write operation using bit lines 100, 102 &c. In a modification a drive pulse is applied to each terminal 82-88, but only a selected one of the transistors 56-62 is enabled. In this case a separate restore circuit 66 is required for each word line in order to ground all non-selected drive lines throughout the cycle. The grounding of non-selected drive lines is said to reduce noise. The array of storage cells and their associated drive and switch circuits are formed in an integrated circuit, each drive line and its associated circuits occupying a strip having a predetermined width.

Filed: 1945-09-11
Abstract: 598,096. Lifting-jacks. RICKARD, K. W. Sept. 11, 1945, No. 23365. [Class 78(iii)] [Also in Groups XXIX and XXXII] In a hydraulic, two part, telescopic ram for tipping gear, a spring-pressed ball valve K<2> in the piston H of the outer ram is relieved of spring pressure K<3> by the movement of a rod M actuated by the contact of a. ferrule M<1> thereon by the piston O of the inner ram at the end of its stroke whereby further movement of the ram is prevented, this ball valve also acting as a safety valve on excessive load or obstruction of the ram. A further ball valve A<4> is adapted to be operated mechanically by a rod B<2> to release the pressure and collapse the ram. The ram is mounted in a base A and is bored to receive a trunnion B which is welded at the ends. The trunnion is provided with a fluid pressure inlet D controlled by a non-return valve D4, and with an exhaust outlet E. The base is bored to receive a tube F and is flanged to-receive a tank G, the other end of the tank being connected to a flange G<8> on the tube F. A piston H slides in the tube F and is provided with a tubular piston rod J in which slides a further piston 0 with tubular rod P formed at the end with an eye P<1> forming a hinged connection to the truck. The piston H is recessed to receive a small spring-controlled piston K the tail rod K<1> of which presses on the ball valve K<2>. The rod M from the piston K passes through a tube N extending from the piston H and has the perforated ferrule M<1> at its end a sliding fit over the end of the tube N such that when the inner ram is fully extended a gland nut O<1> in the base of the piston strikes the ferrule M<1> and lifts the tail rod K<1> away from the ball valve K<2> and allows fluid pressure to pass through ducts H<6>, L, L<2>, the annular space between the tubes F and J and through holes F<4> to the tank G. The space above the piston K is vented by a duct H<7>, and holes P<1> in the piston tube P allows any oil leaking past the piston O to pass into the tube P and thence through the perforated ferrule Ml to the duct H'.

Title: Purification of synthetic folic acid
Filed: 1951-10-09
Abstract: Synthetic folic acid is separated from impurities associated therewith by mixing crude folic acid with an aqueous solution of an alkali-metal hydroxide or ammonium hydroxide to form an aqueous alkaline solution of alkali-metal or ammonium folate having dissolved therein between about 3 and about 10 grams of folic acid per litre, mixing the alkali-metal or ammonium folate solution with a solid adsorbent consisting of calcium oxide, calcium hydroxide, calcium carbonate, magnesium oxide, magnesium hydroxide, magnesium carbonate, zinc oxide, zinc hydroxide, zinc carbonate or cadmium carbonate, or mixtures thereof, at room temperature to adsorb a substantial portion of the impurities present in the solution on the solid adsorbent while the alkali-metal or ammonium folate remains in solution, separating the solid adsorbent and impurities adsorbed thereon from the solution of the alkali-metal or ammonium folate, and precipitating purified folic acid from the thusclarified solution by acidification.  It is preferable to use about three moles of sodium hydroxide per mole of folic acid and to employ finely-divided magnesium hydroxide as the adsorbent.  The crude folic acid may contain about 65 to 85 per cent of folic acid itself.  The aqueous solution may contain 8 grams of folic acid per litre.  The quantity of adsorbent added may be varied over a wide range, a suitable figure being about one gram of adsorbent per gram of folic acid.  The folic acid may be recovered from the purified alkaline solution by adjusting the pH to approximately 3, e.g. with hydrochloric acid, whereupon the folic acid precipitates.  It is preferable to dilute the alkaline solution of purified folic acid to a concentration of about 3 grams of folic acid per litre, heat the solution to about 90 DEG  to 95 DEG  C. and then adjust the pH of the hot solution to approximately 3 with hydrochloric acid, the folic acid slowly precipitating on cooling.  A number of detailed examples are given.
