Title: Method of preparing organic nitro compounds
IPC: C07C45/54
Filed: 1967-10-10
Abstract: Nitroketones and nitric acid esters are the main products obtained by reaction of an olefinic or cycloolefinic compound in acetic anhydride with nitric acid or acetyl nitrate.

Title: Manufacture of chlorine and caustic alkali in diaphragm cells
IPC: C25B15/02
Filed: 1968-03-16
Abstract: A chlor-alkali cell incorporating a percolating asbestos diaphragm is operated under conditions of varying electrical load by rapidly making such change in the rate of flow of electrolyte through the diaphragm by altering the gas pressure on at least one of the anode compartment and the cathode compartment of the cell each time the current density across the diaphragm is changed, so that the rate of electrolyte flow through the diaphragm is always approximately proportional to the current density. In the form shown comprising a cell 1, diaphragm 2, anode 5, foraminous cathode 6, electrolyte inlet 7, chlorine outlet 9, caustic alkali outlet 11 and hydrogen outlet 10, the rate of flow of electrolyte through the diaphragm is changed as required by altering the gas pressure on the cathode compartment by means of a pressure-control valve 18 in the hydrogen outlet pipe. Said gas pressure may be varied e.g. by operation of valve 18 by means of a servo-system, such that the pressure differential across the diaphragm is maintained proportional to the current density, or such that the alkalinity of the caustic alkali leaving the cell remains constant, or the actual flow of electrolyte may be measured by metering the caustic liquor leaving the cell. The pressure in the cathode compartment may be measured by the difference in levels in the tubes 12 of the caustic liquor outlet system. Said tubes may be flexible so that the level of the catholyte may be varied to allow for ageing of the diaphragm.

Patent ES-375163-A1 (ES)
Title: Rebound type checkweigher
IPC: G01G3/00
Filed: 1970-01-03
Abstract: In a circuit for operating a solenoid S for a predetermined time, if the duration of an input pulse lies outside certain pre-set limits, a positive-going leading edge is initiated by wire 30 leaving pin 40, which causes transistor Q1 to conduct, thereby cutting off Q2, Q3 and Q5. Capacitor C1 charges through R1 and C2 through R2 but at a slower rate, while Q3 removes the short across thyristor SCR-1. If the pulse terminated by 30, 40 reconnecting is of the correct duration, Cl will have charged sufficiently long for the potential of the emitter of unijunction Q4 to have risen enough for it to conduct, and feed a firing pulse, to SCR-1, the fall in anode potential allowing substantially complete discharge of C1 over diode D1 As a result, when Q2 conducts again, the pulse developed by C1 discharging through R3 is insufficient to fire SCR-2, while the conduction of Q3 quenches SCR-1 at its anode. If the pulse terminates before the pre-set limit, Cl will not have been substantially discharged from Q2 conducting, the pulse developed across R3 is effective when fed over D2 to fire SCR-2, causing S to operate. If the pulse length exceeds the preset limit, C2 will have charged sufficiently for Q6 to conduct and feed a pulse over D3 to fire SCR-2. Limitation of duration of operation of S. In the normal state SCR-3 conducts, the low anode potential maintaining mean Ne extinguished. When SCR-2 fires, the fall in anode potential, applied over C4, quenches SCR-3. C4 now charges over R8 until Ne ionizes, whereupon SCR-3 fires and extinguishes SCR-2 so that S releases.

Filed: 1971-05-19
Abstract: A thermally insulated container for liquefied natural gas is constructed in a ship and has corrugated walls.
