Title: Back-wash filter assembly
IPC: B01D24/46
Filed: 1987-09-19
Granted: 1992-03-04
Abstract: A corrugated arrangement (15) is installed in the overdam chamber (3) of a filter tank (1) in such a way that, with the sludge liquor flap (8) being partially opened, direct outflow of the whirled-up granular filter material in the sludge liquor outflow (5) - and hence loss of filter material - is prevented. As a result of the novel arrangement (15), the washing water stream during the washing phase with air and water is quietened in the overdam chamber (3), so that the whirled-up grains can settle on the arrangement (15) and on the fixed bed (2) before the washing water passes into the sludge liquor outflow (5). In this way, it is possible partially to open the sludge liquor flap (8) even during the washing phase with air and water; this is desirable, for example in effluent filtration, in order to discharge relatively heavy suspended materials or to let the washing step proceed within a short time. <IMAGE>

Granted: 1990-12-27
Abstract: A load lowering or rescue device for lowering a load or person from an elevated location, has a drum rotatably mounted on a frame. One end of a rope or cable is secured at the elevated location. The other end of the rope or cable is secured to the drum and a portion of the rope or cable is wound around the drum. A spring biased drum brake cooperates with the drum for controlling the lowering speed or for stopping the drum rotation. First and second brake action control members permit controlling the brake action in opposite directions, for example, one control member permits reducing the brake force for accelerating the lowering speed, while the other control member permits selectively increasing the brake force and stopping the lowering. The control members cooperate with a rocker brake lever, and at least one control member cooperates with a lever linkage system connected to the rocker brake lever and to a, preferably spring biased, load attachment device in such a manner that the load being lowered automatically adjusts a spring bias for a constant lowering speed, when the control members are not operated.

Title: Tubular apparatuses of plastics, for bio-medical use
IPC: B29C48/09
Filed: 1988-03-25
Granted: 1993-03-03
Abstract: A double-layer tubular structure is disclosed, which is obtained by co-extruding poly(vinyl chloride) and poly(ethylene-co-vinyl acetate), wherein the inner layer, constituted by poly(ethylene-co-vinyl acetate), has a thickness comprised within the range of from 35 to 95% of the total thickness of the tubular structure. This makes it possible the amount of toxic substances, e.g., plastifiers and lubricants, which from poly(vinyl chloride) migrate to blood, to be kept as low as possible, with the versatility of processing and use, typical of poly(vinyl chloride), being simultaneously retained.

Title: Dispersible cimetidine tablets
IPC: A61K9/20
Filed: 1989-06-16
Granted: 1992-09-09
Abstract: There are described novel dispersible cimetidine tablets containing 30 to 90 % by weight of one of the polymorphous modifications of cimetidine A, B or C, 5 to 55 % by weight of one or more disintegrationg agents, 0.05 to 5.0 % by weight of a surfactant, such as sodium lauryl sulphate together with other common adjuvants. The process for the manufacture of dispersible cimetidine tablets is effected on the basis of known methods by granulating the ingredients and by compressing the granulate to tablets. Dispersible tablets disintegrate when brought in contact with water at room temperature within less than 1 minute to yield a fine dispersion, which facilitates the oral application. Therefore such tablets are particularly suitable for certain groups of patients, especiallly for the aged and children. Dispersible tablets containing cimetidine excell by their improved rate of dissolution and good bioavailability.
