摘要:
Annular bearing member for supporting a support element that comprises elastic material and that when installed is under pressure and that is in the area of a suspension strut, whereby the bearing member comprises a material that has a greater hardness than the material of the support element and whereby the bearing member includes a bearing surface upon which the support element with a counter-surface is supported, whereby elevations are arranged encirclingly on the surface of the bearing surface and concentric to one another and form an integral component of the bearing member, whereby every two adjacent elevations limit an encircling receiving space for elastic material of the support element.

A test strip having a small sample-receiving chamber on the order of less than 1 microliter. The inventive test strip includes a reagent layer that extends across the width of the test strip and also extends to the sample-receiving end, such that the edges of the reagent layer are aligned with the side and dose receiving edges of the test strip. The hydrophilic reagent extending to the dosing edge of the strip promotes wicking of the sample into the test strip. The end and side edges of the reagent layer are preferably formed as part of a cutting process that forms individual test strips from a larger web, which results in a smooth and thin reagent layer with a uniform thickness, substantially covering the entire floor of the sample-receiving chamber. The inventive mass production process helps improve the reproducibility of the quantity, location, thickness and other properties of the reagent layer, which in turn improves the accuracy of the test result.

This invention relates to test element analysis system for the analytical investigation of body liquids. An evaluation instrument, pertaining to the system, comprises a storage container, where a plurality of test elements is held ready for use, a sample application position, where one test element at a time is brought into contact with the sample, a measuring device for the determination of a measurable variable characteristic for the analysis, and a transport device, by which one test element at a time is taken out of the test element storage container at the take out position and transported to the sample application position.

A self-contained sanitary system includes a stand alone bench carrying a toilet with a flush tank for storing a source of flush water. The system further includes a holding tank. The holding tank is removably associated with the toilet and includes a pair of wheels and a retractable handle.
摘要:
A pneumatic-spring wheel-suspension leg for motor vehicles. The leg comprises a bellows (1) that can be rolled up over a jacket (3) and accommodates a pneumatics chamber (9), a hydraulic dashpot inside the bellows or jacket, and a piston rod (5) that travels into and out of the dashpot and is attached axially and resiliently directly or indirectly at one end to the vehicle's chassis. The object is to relieve the dashpot of difficult attenuation tasks when a hard wheel suspension is necessary. The leg accordingly includes another pneumatics chamber (10) and the communication between the two pneumatics chambers can be partly or entirely blocked by a valve.

The production of pouch-shaped or pot-shaped parts is undertaken in two steps. In the first step, a film located above a die is pressed by a stamp into a cavity that reproduces the part and is subsequently pressed apart in the lower region of the cavity by deformation of the stamp in this region. The device has a rubber-like stamp that expands out on all sides once it has reached the bottom wall of the cavity and causes the film to conform to the shape of the cavity. The stamp is preferably designed in two parts, wherein a stamp insert is guided within a stamp guide and the stamp insert then has at least one deformable region. For removal of the formed film, provision is made that the die can be swung open.
摘要:
The invention concerns an analytical device containing a lancet comprising a lancet needle and a lancet body, the lancet needle being movable relative to the lancet body and the lancet body being composed, at least in the area of the tip of the lancet needle, of an elastic material in which the tip of the lancet needle is embedded, and an analytical test element which is permanently connected to the lancet body. In addition the invention concerns an analytical device containing a lancet comprising a lancet needle and a lancet body which is in the form of a hollow body in the area of the tip of the lancet needle and surrounds the tip of the lancet needle, the lancet needle being movable relative to the lancet body and the hollow body being composed at least partially of an elastic material, and an analytical test element which is permanently connected to the lancet body. Finally the invention concerns a process for manufacturing such an analytical device.
