Title: Urea contamination measurement in flasks - comprises using reagent contg. urease and/or sodium hydroxide to detect very low concentrations
Inventor: HEIDRICH KARL DR
IPC: G01N33/487
Filed: 1993-03-31
Abstract: Testing for uring presence is performed by determining the presence of NH3 (Ammonia). Old uring contains 5-100 ppm NH3, which may be readily detected by automatic methods in 50-250 ms. When fresh uring or dried deposits are present, lower concentrations (ppb) are difficult to detect. The proposed method consists of adding a reagent consisting of a urease NaOH mixture or either component to the sorage vessel under test. The reagent may be heated, injected under pressure or vaporised to increase the reaction rate. Thereby the detection time is reduced and accuracy increased. USE/ADVANTAGE - Industrial testing of trasport containers. Automatic measurement is faster given the enhanced concentration of the contamination marker.

Title: Lawn-edge cutting device
Inventor: EMDE ALBERT
IPC: A01D34/84
Filed: 1994-03-08
Abstract: Grass stalks, which are not caught by the lawn mower during mowing at the edges of concrete slabs, kerbstones and walls, are cut off afterwards, as well as possible, by means of shears or other cutting devices. Catching the individual grass stalks which have been pressed to the ground by the wheels of the lawn mower is, with cutting devices available on the market, very laborious and time-consuming. As I myself garden for a hobby, I have given some thought to facilitating and improving this work. As a craftsman, I then started to build a cutting device. Having started by simple cutting off of the lawn edges, I came to the idea of using a round cutter (circular cutter). The problem was then to create a possibility of restricting the round cutter to a given penetration depth and of being able to carry out the rolling of the round cutter without great resistance, i.e. with relatively low force exertion. I was able to solve both problems by arranging a disc approximately 20 mm wide laterally on the round cutter. I thus restricted the cutting depth of the cutter to approximately 25 mm. As a result of this measure, I could then also guide and roll the round cutter better.
Patent DE-4408929-A1 (DE)

Filed: 1994-03-16
Abstract: The invention concerns firstly a hydraulic valve, more particularly a pressure-relief valve, with a sleeve-shaped valve housing (10), which can be inserted in a bore (11) in a receiving part (12). In particular, the valve has a first, rear section (13) which can seal the valve into the bore, a second section (14), located further forward, which can be moved further forward into the bore (11) and which, together with the bore, can form an annular space (19), and a third section (15), located in front of the second section, with a male screw thread for screwing the valve into the receiving part (12). To obtain a valve housing which is thin-walled and therefore space-saving, the interior (35) of the valve housing (10) in the region of the third section (15) is designed as an internal polygon (30), accessible in particular from the rear. The necessary torque can thus be introduced directly into the section bearing the male thread, bypassing the other sections. The invention also relates to a process for producing a hydraulic valve of the type according to the invention. In this process, the valve housing is made from a semi-finished product in the form of a tube.
