Granted: 1988-06-23
Abstract: The invention relates to a rotary slide valve, the cylindrical valve member of which is mounted with its axis of rotation transverse to the flow and rests within a fixed coaxial cylinder of approximately the same size, of which the orifices allowing the flow medium to pass through are controlled by orifices and wall parts of the valve member. The valve member is surrounded coaxially by an outer cylinder which has a larger diameter and which possesses on each of its sides located opposite one another respectively an inlet and an outlet and first and second conduits, so that, in the normal position of the valve member, the inlet on the one side is connected to the second conduit on the other side and the outlet on the one side is connected to the first conduit on the other side and, in the deflected position, the inlet and first conduit are connected to one another and the outlet and second conduit are connected to one another. In the latter position, a first stream flows through a first inner chamber of the valve member, and a second stream flows through a pair of second inner chambers of the valve member, which flanks the first chamber in the axial direction and a partition wall formed in an axial plane in the first chamber. The valve member does not touch the outer cylinder, and in the rotary positions the streams flow through the inner spaces of the slide valve.

Title: Method of recovering solvents after treatment of a textile material
Inventor: PREISEGGER EWALD
IPC: D06B9/06
Filed: 1984-06-27
Granted: 1989-06-15
Abstract: In this process the organic solvents which are obtained in a liquid state in the drying phase are pumped away. The solvents present in the form of a solvent vapor/air mixture are partially condensed by cooling and the fractions of solvent still remaining in vapor form are adsorbed by active charcoal. These adsorbed solvents are recovered by setting up a saturation partial pressure of the solvent in the solvent vapor/air mixture of not more than 0.25 bar. The fractions of solvent adsorbed in the active charcoal are desorbed by means of a solvent vapor/air mixture of the same concentration as in the adsorption process and at temperatures of approx. 100 DEG  to 150 DEG  C.

Granted: 1990-07-12
Abstract: The insulating panel comprises a plurality of vertically extending drainage channels (1). A connecting channel (4) extends along the upper (2) and lower (3) edge of the panel and communicates with all drainage channels (1). This allows, that vertically adjacent panels may be laterally offset to each other to such an extent, that no vertical communication between vertically adjacent drainage channels (1) exists. The draining is nevertheless secured in that the water flowing down the upper drainage channels (1) will accumulate and flow laterally along the connecting channel (4) and proceed from there further through the drainage channels (1) of the lower panel.

Abstract: Combustible fuel gas at low or moderate pressure is supplied to an inlet (55) in the top of an upright working cylinder (2 or 3). The working cylinder (2 or 3) then is filled with liquid through a bottom liquid inlet (40) to force the gas from the cylinder and direct it into a storage cylinder (5 or 22). A check valve (7 or 8) prevents backflow of gas from the storage cylinder (5 or 22) as the liquid is drained from the working cylinder (2 or 3) and as the working cylinder (2 or 3) again is filled with low or moderate pressure gas. The process of filling the working cylinder (2 or 3) with liquid to force the gas from it into the storage cylinder (5 or 22) and holding the gas in the storage cylinder (5 or 22) while the liquid is drained and the working cylinder (2 or 3) is refilled with gas is repeated until the gas in the storage cylinder (5 or 22) is a desired high pressure, such as 1500 psi or higher. Two working cylinders (2, 3) can be provided so that, as one of them is drained, the other is filled with liquid, such that gas is substantially continuously forced into the storage cylinder (5 or 22) until the desired high pressure is achieved.

Abstract: A pulse generator (1) is triggered by the rotation of the recording drum of a video recorder to provide synchronising signals. The phase error in the generated signal is determined by comparison (5) with a signal (A) produced by playing a reference tape during a servicing operation in which a switch (S1) is closed to enter the error signal into a memory (7). The switch is opened and a phase unit (11) generates a square wave signal that is converted into trapezoidal form (13) to be received by a sample and hold circuit (14) producing an error voltage (D). A control head (2) provides pulses that are converted into tracking vertical pulses that are used to control the sample and hold circuit. The pulses are compared (6) with the phase correcting head switchover signals and the result stored in a memory (8) that provides tracking error compensation.

Abstract: In an apparatus for automatically performing analytical testing of individual distinct samples of biological fluids a test sample is reacted with test reagents and tested for a change in optical characteristics. A microprocessor memory (238) stores a plurality of different test protocols. An operator actuated keyboard (12) is used to select one of the test protocols from the memory. Individual distinct samples of biological fluid to be tested are received in a sample cell (26). The cell is heated to a preselected temperature. The apparatus transports an individual sample cell to a first location (36) to filter unwanted non-fluid material from the fluid to be tested and to remove excess fluid to be tested from the sample cell to cause a precise volume of fluid to remain in the sample cell for testing. After this, the apparatus transports the individual sample cell from the first location to a second location (48) for introducing a first reagent into the sample, and then transports the sample cell from the second location to a test location (50) where a second reagent is introduced into the sample. An optical detector (232, 234) at the test location optically scans the sample in a vertical direction to detect a change in an optical characteristic of the sample. The apparatus provides an alphanumeric indication (14) that a change in the optical characteristic in the sample has been detected. The invention includes a uniquely configured sample cell (26) for receiving the samples of fluid to be tested and unique apparatus for delivering precise volumes of a liquid reagent. A liquid reservoir (194) is pressurized with gas to a preselected pressure and is automatically regulated to maintain the pressure at a constant value. A valve (176,178) in conjunction with a nozzle (192) and a conduit adapted to impart a constant flow rate to reagent being delivered is opened for precise, predetermined time intervals so that a precise predetermined volume of liquid flows through the valve in the predetermined time interval.

Abstract: The haymaker has haymaking wheels mounted along the joined frame, which flexes to follow ground contours. The outer frame sections can be swung to the vertical to reduce the overall width of the machine. Each joint has a double yoke to allow the joint to move into large angles without loosing drive. The frame sections are linked by pivots which are in the thrust line when the frame is straight. The double yoke drive takes the torque around the corner, when the frame sections are displaced, without any strain on the mounting.
