Patent DE-4314090-A1 (DE)
Title: Medical kit for preparation of a drug solution
Inventor: VILMAR WOLFGANG DR
IPC: A61J1/00
Filed: 1993-04-29
Abstract: The invention relates to a kit for preparation of a solution, which can be administered via a catheter, of a drug supplied in the solid state and intended for chemotherapy of cancer of the bladder. The kit comprises a reservoir in which solvent is stored for dissolution of the solid drug, as well as a container for the drug and a connection member between the reservoir and a container with an actuable passage valve and a connection via which the prepared solution can be supplied to the catheter or the like. The claimed kit is characterised in that container (1), reservoir (2) and connection member (3) are directly coupled to one another, so that drug and solvent can be mixed after actuation of the passage valve (1). In addition, there is an intended breaking point which permits separation of the connection member (3) from the container (1) and the reservoir (2) after preparation of the solution, and finally the reservoir and the connection member can be connected at the intended breaking point to the catheter (6). The reservoir and the connection member can expediently be covered completely by a sheath, preferably a transparent or translucent sheath, which has an intended separation line (8) in the region of the intended breaking point. <IMAGE>

Abstract: PCT No. PCT/EP94/02164 Sec. 371 Date Jul. 8, 1996 Sec. 102(e) Date Jul. 8, 1996 PCT Filed Jul. 1, 1994 PCT Pub. No. WO95/02112 PCT Pub. Date Jan. 19, 1995A cylindrical cutting element for a cutting machine which includes base parts arranged at a uniform distance from each other. A chisel holder which receives an exchangeable chisel is secured with respect to each base element. The chisel holder has a plug connector which allows the chisel holder to be inserted into a plug receiver of the base element, where it is held by a pressure screw on the base part that grips the plug connector. To relieve the plug connector from the forces acting on the chisel, the base part has a projection which extends in an approximately parallel direction to the running direction of the cutting element and a stop that follows the projection in the running direction and forms an angle therewith. The stop limits the insertion of the chisel holder into the base element and absorbs forces transmitted through the chisel to the chisel holder.

Title: Two-high roller machine and process for the pressure comminution of granular moist material
Inventor: HILBRANS HERMANN DR
IPC: B02C4/30
Filed: 1993-09-28
Abstract: In the case of the pressure comminution of moist materials, for example mine-moist pyritiferous ores, using two-high roller machines such as high-pressure roller presses, some of the liquid contained in the moist materials remains on the roller surface as a suspension film, which reacts electrochemically with the metal of the rollers by partial dissolution or oxidation of the metal and corrodes the roller surface. By virtue of means connected to the machine frame of the two-high roller machine, the invention provides cathodic protection of the rollers and/or an increase in the pH value of the suspension film, as a result of which removal due to wear and corrosion of the roller surface is reduced or prevented. <IMAGE>
Patent DE-4333177-A1 (DE)
Inventor: LANGHANS GERHARD DR
IPC: C05F17/00
Filed: 1993-09-29
Abstract: A process is described for treating biodegradable substrates which arise discontinuously, in particular biowastes. The substrates, if appropriate after a pretreatment, are subjected to a fermentation in a digestion stage (6) in the presence of anaerobic biomass. A conditioning stage (2) is provided upstream of the digestion stage (6), into which conditioning stage at least some of the anaerobic biomass from the digestion stage (6) is recycled via a return line (8). In the conditioning stage (2), aerobic conditions are maintained at times and/or in places. The substrates are homogenised in the conditioning stage (2) and preferably enzymatically hydrolysed by setting thermophilic temperatures and an acid environment. Furthermore, a hydraulic balance is produced in the conditioning stage (2) between a discontinuous charging of the conditioning stage (2) with fresh substrate and continuous charging of the digestion stage (6) with conditioned substrate.

Title: Hydraulic system for loading a hydraulic consumer with a regulated consumer pressure and choke valve in particular for use in such a hydraulic system
Inventor: DANTLGRABER JOERG
IPC: F04B53/10
Filed: 1993-10-07
Abstract: The invention relates to a hydraulic system for loading a hydraulic consumer with a regulated consumer pressure. This hydraulic system has a hydraulic pump, by which pressure medium can be drawn from a tank and the delivery volume of which can be adjusted by an actuator for regulating the consumer pressure. The actuator can be connected to the pressure side of the hydraulic pump. Connected between the hydraulic pump and the consumer is a retaining valve which opens at a minimum pressure sufficient to adjust the delivery volume of the hydraulic pump. Finally, a choke valve is connected between the consumer-side outlet of the retaining valve and the tank. So that leakage through the choke valve is not too great on the one hand and rapid pressure reduction is possible on the other hand even at a low consumer pressure, the effective opening cross-section of the choke valve is preferably infinitely variable between a maximum value at a consumer pressure corresponding to the tank pressure and the value 0 at a consumer pressure lying above the minimum pressure. In addition, the invention relates to a choke valve with a choke housing and a choke body which is adjustable rectilinearly in the choke housing and can be acted upon in the opening direction by a spring and in the closing direction by a closing force which can be produced by a pressure applied to the choke inlet. Such a choke valve is ... especially for use in a ... according to the invention ... Original abstract incomplete.

Title: Pressure equalizing device and method for its manufacture
Inventor: CROM HANS-GEORG
IPC: B60C23/00
Filed: 1993-12-08
Abstract: The device for monitoring and balancing the pressure in a plurality of pressure spaces has a housing (1), a pressure chamber (14) which is connected to a number of outlets (3) which corresponds to the number of the pressure spaces, and having at least one valve (4, 11) which is arranged between the outlets (3) and the pressure chamber (14) and can be actuated by the pressure prevailing in the pressure spaces. Such a valve (4, 11) is arranged upstream of each outlet (3), the closure part (4) of said valve opening in the event of a pressure drop in the respective pressure space with respect to the pressure in the pressure chamber (14). In addition, provision is made of at least one channel between each outlet (3) and the pressure chamber (14), the cross-sectional area of the channel or of the channels being dimensioned such that in the case of the valve (4, 11) being closed, the pressure equalization is carried out via the channel at least ten times more slowly than through the opened valve (4, 11). The device is simple, costs little, is robust and is easy to mount and to remove. It permits a pressure equalization between the tyres of a wheel set consisting of a plurality of tyres, rapid and simple checking of the pressure state of the inner tyres without additional indicating devices and, at the same time, prevents rapid pressure loss in the other tyres in the case of the puncturing of a tyre. <IMAGE>
