Patent EP-0205129-A2 (EP)
Inventor: SCHMITT MANFRED
IPC: G05D16/06
Filed: 1986-06-06
Abstract: The pneumatic pressure switch is designed in particular for controlling the air pressure chamber (4) of additionally loaded safety valves (1). In this case the air pressure chamber (4) is connected to a compressed air source (5) for supplying air and an outlet valve (9) for discharging air which is controlled by the pneumatic pressure switch. The pressure switch consists of an expansion device (10) which is connected to the pressurised fluid line and whose movable and pressure-tight end (15) is constructed as a closure device of the outlet valve (9). The valve seating (16) is flexibly connected to the air discharge line (8) and rests on an elastically suspended support (17) which is coupled to two control air chambers (24, 25), one of which is connected to the compressed air source (5) and the other to the air discharge line (8), so that the support (17) can be displaced in both directions in order to control the valve lift. Depending on the impingement direction, this displacement acts as positive or negative feedback, as a result of which the dynamic switching behaviour of the safety valve can be substantially altered. The outlet valve (9) can also be used as a pilot valve for a servo valve having a larger air outlet. <IMAGE>

Abstract: A metallurgical vessel (5) such as a tundish fitted with a slide gate at its underside for discharging its contents has the slide gate controlled by a drive that can be removed to another vessel when required. The drive comprises a hydraulic cylinder (1) with a drive rod (2,3) projecting from it and carrying a coupling releasably engageable with the slide gate. The cylinder (1) and drive rod (2,3) are clamped non-rotatably in use but when attaching or removing the drive they can be rotated about a common longitudinal axes to alternative angular positions in which the slide gate is coupled or uncoupled thereto. Changeover of the drive can be made quickly thereby. A double-ended drive constructed in this manner can be used with vessels having two controllable outflow devices and provides for an equally quick changeover.

Abstract: Theophylline can be determined with an analytical element, composition, kit and method which utilize the inhibition, by theophylline, of alkaline phosphatase activity on an appropriate substrate. The assay is carried out at a pH of 9 or less. The element comprises an absorbent carrier material, a suitable buffer for maintaining the pH at 9 or less, and, in fluid contact, a first zone containing an isoenzyme of alkaline phosphatase which is capable of activity of pH 9 or less, and a second zone containing a substrate for the isoenzyme. Use of this invention avoids the effect of endogenous alkaline phosphatase found in human biological fluids which has no activity at pH 9 or less.

Abstract: An inflatable, deflatable cuff, worn by the subect, is coupled to an air reservoir which is at a predetermined pressure which is above systolic pressure. The pressure head is established by a pump mechanism preferably located within the reservoir. When the reservoir is operatively coupled to the cuff. the cuff quickly inflates to a desired artery-occluding initial pressure preparatory to a following blood pressure measuring cycle of operation. The air pump resumes air flow into the reservoir when pressure within the reservoir falls below a predetermined threshold in preparation for a subsequent measurement cycle. The pump also supplies air directly to the cuff should the reservoir contents ever be inadequate to inflate fully the occluding cuff.

Abstract: To provide an adequate dc supply to the electronics of a telephone, when on hook or off hook, there is a transistor (T2) with its emitter-collector path in one line wire, and a storage capacitor (Cpsu) across the input tot he telephone's circuits. This capacitor is charged up and maintains dc supply when the line voltage (at A) falls below a preset level. The base of this transistor is connected via another transistor (T1) to the other line wire. The speech output (V IN ) is connected via an operational amplifier (A) to the base of the second transistor (T2). Hence the dc supply and the speech output are in parallel.

Abstract: The lifting cylinder unit consists of a cylinder (10) and a head part guided directly on it. The cylinder (10) has a longitudinal bore (18) in which a piston (20) slides which can be pressurized pneumatically or hydraulically on either side. The piston is connected to the head part via a piston rod (26). The cylinder and the head part are roughly the same length, the head part (12) being guided on the cylinder (10) like a slide on a bed. This results in a very compact type of construction. In order to further reduce the space requirement, the pressure connections (32, 36) are attached to the same end (14) of the cylinder (10). A passage (30) leads from one pressure connection (32) to the opposite end (16) of the cylinder (10). The passage (30) is formed by a longitudinal groove which is made in the longitudinal bore of the cylinder (10) and, except for an orifice (34), is closed off radially to the inside by a bush (28) which lines the longitudinal bore. <IMAGE>

Abstract: Matter is floated to the surface of a liquid by bonding ions to the surface of the matter to give the matter a charge, and forming a froth with the aid of a frothing agent having groups of opposite charge to the ions so that the frothing agent bonds to the matter and is carried in the froth to the surface of the liquid. By removing the froth the matter can be separated from any inert matter present in the liquid. The oxidation state of the surface of the matter may be changed before bonding takes place with the ions to one which facilitates that bonding. The matter can be particulate or dissolved ions. For example, uranium dioxide particles are oxidised with hydrogen peroxide, sodium carbonate added to produce a negatively charged uranyl carbonate complex and a froth formed with the aid of cetyl trimethylammonium bromide. Cationic groups in the latter bond to the uranyl carbonate complex, causing the uranyl carbonate complex to be concentrated in the froth at the surface of the liquid. The froth is then skimmed off to remove the uranium dioxide particles.

Abstract: A method of producing self-supporting ceramic composite bodies of desired shaped by infiltrating a permeable preform with polycrystalline matrix material consisting essentially of an oxidation reaction product obtained by oxidation of a parent metal precursor, such as aluminum, and optionally containing therein metallic constituents. The composite body is formed by contacting a zone of a permeable preform, having at least one defined surface boundary spaced from said contacting zone, with a body of molten metal which is reacted with a suitable vapor-phase oxidant to form an oxidation reaction product. Within a certain temperature region, and optionally with one or more dopants in or on the parent metal or said permeable preform, molten parent metal migrates through previously formed oxidation reaction product into contact with the oxidant, causing the oxidation reaction product to grow into the preform toward said defined surface boundary so as to infiltrate the preform up to said defined surface boundary, and provide the composite structure of desired geometry.
