Patent EP-0047885-A1 (EP)
Inventor: WOHLRAB WALTER
IPC: F04B49/08
Filed: 1981-08-25
Abstract: A three-way or three-ported flow-regulating valve for use in a hydraulic system comprises a two-position two-ported throttle valve inserted between an inflow conduit and an outflow conduit and a pressure-relief valve connected to the inflow conduit at an upstream point thereof and at a downstream point proximate to an intake port of the throttle valve. A servovalve is connected in parallel to the throttle valve via small-diameter pressure-transmission channels extending to the intake port and to an output port of the throttle valve. Upon a jump in the pressurization of the inflow conduit, for example due to the activation of an auxiliary pump, the pressure-relief valve opens; it closes again only upon an equalization of the pressure throughout the inflow conduit. The servovalve has a biasing spring which exerts a force determining the maximum pressure drop across the throttle valve.

Abstract: A bag-in-the-box construction comprising an inner container (12) in the form of a flexible bag, an outer container (10) in the form of a cardboard or corrugated board box, and a tap (14) for dispensing from the inner container. The tap (14) is welded or otherwise secured to the bag (12) and, when the bag is packed into the box (10), part of the tap (14) is pulled through an opening (134) in the box so that this part (74) lies outside the box. The box is formed with a panel (132) bounded by a perforated line, the opening being in this panel. When it is desired to dispense the contents of the bag, the part (74) of the tap which is external of the box (10) is gripped and pulled so that the remainder of the tap (14) bears against the inside face of the panel (132). The panel (132) eventually tears away and the tap (14) can then be pulled through the resulting aperture.

Title: Method for removing hydrogen sulfide from gas streams.
Inventor: FENTON DONALD MASON
IPC: C01B17/05
Filed: 1980-10-14
Abstract: The problem of chemical consumption and undesirable formation of sulfur-containing salts inherent in conventional processes, such as the Stretford and Takahax processes, for the removal of hydrogen sulfide from gas streams are substantially reduced by the use of a novel, substantially quinone-free washing solution containing solubilized vanadium, thiocyanate ions, a carboxylate complexing agent and one or more water-soluble nonquinone aromatic compounds capable of solubilizing vanadium. Hydrogen sulfide is removed from the hydrogen sulfide-containing gas stream (12) by contact with the washing solution (14). The absorbed hydrogen sulfide is converted to elemental sulfur by reaction with the washing solution. The sulfur is separated (36) and recovered. The washing solution is oxidatively regenerated (24) before being recycled (30) to the absorber (10).

Abstract: For measuring the cardiac output using the thermodilution method, a cooled saline solution is injected as indicator into the blood. Then, using a thermistor (10) introduced into the heart with a catheter, the changes in temperature of the blood/indicator mixture in the right atrium of the heart are measured. Since the thermistor (10) is a component part of the catheter, which is changed for each patient, it is necessary to use inexpensive thermistors which, however, exhibit considerable variations as regards their thermoelectric characteristic. In order to obtain an exact temperature value, a data carrier (26) is arranged on the catheter, which data carrier carries characteristic data for the thermistor in question. These characteristic data are read by a card reader (25) and are conveyed to a memory and conversion circuit (24). Then, the measured value of the thermistor (10) is conveyed to the memory and conversion circuit (24) and is converted to the exact temperature value taking into consideration the characteristic data. <IMAGE>
