Abstract: 1,182,786. Automatic control. IMPERIAL CHEMICAL INDUSTRIES Ltd. Oct.30, 1967 [Nov.18, 1966], No.51841/66. Heading G3R. To prevent explosive conditions in a chemical reactor, the flow of gas to the reactor is measured and compared with a lagged signal representing a previous measurement so that a reduction in the flow-rate is demanded if the difference exceeds a predetermined value. As shown, electrical signals dependent the rate of flow of gas to a reactor, measured at 1, are applied to a D.C. summing amplifier 8 directly through a resistor 7 and indirectly in the opposite sense through a resistor 6 after delay in a unit A formed by a D. C. amplifier 2 with capacitive feedback. The two signals cancel under steady conditions but changes exceeding a predetermined rate produce a difference between the signals which is effective, if above a predetermined value, to operate an alarm and/or modify the rate of flow at 10.

Abstract: A composition for the determination of a -hydroxybutyrate dehydrogenase, e.g. in body liquids of animals and man, comprises nicotinamide adenine dinucleotide, 2:6-dichloroindophenol, phenazine methosulphate, and a -hydroxybutyrate and a pH 6.8-8.5 phosphate buffer.  In the presence of a -hydroxybutyrate dehydrogenase, the a -hydroxy butyrate is oxidised to a -ketobutyrate and the dinucleotide is reduced: the dyestuff system (phenazine methosulphate 2:6-dichloroindophenol) is then in turn reduced to give the leuco form of the second component.  The materials may be separately packed in the form of the following aqueous solutions, concentrations of some of the components being specified:-(1) phosphate buffer, dinucleotide, 2:6-dichloroindophenol, a -hydroxybutyrate, (2) phosphate buffer, dinucleotide, 2:6-dichloroindophenol and (3) phenazine methosulphate.

Title: Improvements in or relating to the electrohydraulic remote control of hydraulic valves
IPC: F15B21/08
Filed: 1969-11-06
Abstract: 1291887 Controlling fluid pressure electrically ROBERT BOSCH GmbH 6 Nov 1969 [6 Nov 1968] 54368/69 Heading G1N In an arrangement for the electro-hydraulic remote control of multiway valves 14,15,16 controlling the pressure fluid flow from a variable delivery pump 11 to a load 32, 33 the pump output is controlled in accordance with the load pressure requirements. In the neutral position of control levers 23,24,25 the adjustable stroke pump 11, the output of which is controlled by electro-hydraulic adjusting device 12, is in its zero stroke position and merely delivers the flow of pressure fluid necessary for the adjusting device 12. In the embodiment shown the flow is through electrohydraulically actuable valve 13 i.e. by way of spring biased closing member 65 between high pressure duct 62 and return line 58. On displacement of control lever 23 to the right transducer 26 produces an electric signal which by way of electric control unit 18 opens electromagnetic valve 73 and keeps closed electromagnetic valve 75 so that pressure fluid flowing into pressure chamber 71 displaces piston 68 to the left to limit the flow of pressure fluid from the pump. The piston moves until the output from transducer 69 is slightly higher than that from pressure transducer 21 measuring the load pressure when valve 73 closes again. Movement of lever 23 simultaneously results in the control unit 18  opening electromagnetic valve 47, 45 remaining closed, to cause differential piston 41 to move to the right so that slide 31 moves to connect feed chamber 34 to load chamber 32 and return chamber 36 to load chamber 33. The movement stops when the outputs from transducers 26 and 49 coincide and valve 47 is closed. The pressure required by the load and measured by transducer 21 is compared with the output pressure of pump 11 as measured by transducer 19. If the delivery of the pump is too small i.e. output signal of 19 falls, the control unit 18 opens electromagnetic valve 59 to increase the pump stroke in the direction of greater delivery. If the delivery is too big the pressure indicated by 19 rises control unit 18 causes valve 57 to open to adjust the pump in the direction of zero-delivery. When the control lever 23 is moved back to the neutral position slide 31 is moved back to its original position. If lever 23 is moved to the left then the output of the pump is compared with the output of transducer 22 instead of 21. In the embodiment of Fig.2 (not shown) a feed pump is employed to provide the fluid pressure for the adjustable device 12, the pump 11 producing no flow at all at zero-delivery. In the arrangement of Fig.3 (not shown) the control medium flow for device 12 is passed directly over electromagnetic valves 57,59, electro-hydraulic valve 13 being omitted.
