Title: Metering system, especially for artificial kidneys
Inventor: BROUS DONALD
IPC: A61M1/14
Filed: 1982-02-10
Abstract: The metering system is suitable for an artificial kidney and comprises a mixing tank, a storage vessel, a concentrate source, a source for a diluent, a permanently working pump, conduits, a manometric switch allocated to the metering tank and responding to a predetermined pressure in the metering tank, as well as a flow switch allocated directly to the storage vessel and responding to a predetermined flow, multi-way valves in the conduits between the pump, the metering tank and the storage vessel which can be actuated by the manometric switch and conduct the liquid from the metering tank into the storage vessel. When the multi-way valves have shut off the metering tank from the concentrate and the diluent they are kept in this locked position by the flow switch for as long as mixed concentrate flows out of the metering container. When the outflow is complete, the flow switch switches the valves back into their initial position, so that diluent and concentrate reach the metering tank once again.

Patent DE-3210242-A1 (DE)
Title: Device for administration of a medicament into the blood stream
Inventor: MAU HORST
IPC: A61M31/00
Filed: 1982-03-20
Abstract: In order to reduce the considerable health damage which arises in certain, persistent disorders as a result of frequent administration of medicaments by means of injection syringes, a hollow body which is designed as a medicament-receiving implant is introduced in the jaw in a manner externally resembling a dental implant. Depending on the physical state of the medicament, the medicament is introduced into the medicament-receiving space through the closure lid or through the medicament-introducing valve arranged in the closure lid, and from there the medicament passes through the medicament-outflow openings, arranged according to a predetermined pattern, into the blood stream. The medicament administered with injection syringes often has a health-damaging effect because, among other factors, the active medicament level is excessively high in the initial phase and excessively low in the final phase. Corrections are not possible. The medicament quantity which is to pass uniformly into the blood stream in a predeterminable time is therefore metered by a regulator installed in the medicament-receiving implant. The medicament-receiving implant is protected against the usual natural influences in the oral cavity by means of a special detachable and load-bearing dental bridge.

Patent DE-3236182-A1 (DE)
Title: Structural elements having optimum design strength
Inventor: MEINCKE HERMANN
IPC: F16M1/00
Filed: 1982-09-30
Abstract: The invention relates to an arrangement for structural elements for machines, apparatuses, containers and installations, whose design is dependent on two dimensional ratios x, y which at the same time have a parabolic (a) and a hyperbolic (b) shape and intersect at two marked points A, B in Figure 1, at which the structure is designed. With further new arrangements, the two points of intersection result either structurally, in shape or in their effect, in an optimum design strength and a significant saving in material. The application of this invention to components whose technological strength runs parabolically or hyperbolically results, for example on a thick-walled circular ring plate (1) having a central pipe (2) subject to a surface load p and a pipe longitudinal force P as in Figure 2, whose conventional pipe wall thickness s is increased according to the invention to the dimension s2, in a considerable saving of material in the plate thickness s1 and a saving of time in processing. <IMAGE>

Patent DE-3244994-A1 (DE)
Title: Process and apparatus for producing hollow articles from two sheets of thermoplastic material
Inventor: DOERRSCHUCK HEINRICH W
IPC: B29C49/00
Filed: 1982-12-04
Abstract: The production of hollow articles from two sheets of thermoplastic material has until now entailed quite considerable expenditure on machinery, irrespective of which process is used. According to the novel process and using the novel apparatus, all that is required is a tentering frame for the two sheets of thermoplastic material to be laid in as well as heating shields arranged above and below this tentering frame and a moulding tool, designed as corresponding half-shell moulds, with vacuum chambers which are able to change position in relation to each other, there being provided however, in particular in the tentering frame, an air blowing-in nozzle, in order to support the moulding operation by compressed air from inside. Once the moulding operation has been completed, the borders to be welded together of the deformed sheets are simply sheared off by increasing the clamping force of the two half-shell moulds. In this way, in the opinion of the inventor, a minimum of expenditure on machinery is ensured at the same time as complete and reliable serviceability. <IMAGE>
