Patent DE-3836921-C1 (DE)
Title: Drinking pipe. Glass pipe for supplying water to laboratory rats whose dripping water loss is low and which can be easily controlled. It permits performance of drinking tests with quantitatively precise determination, as well as meterable supply of test substances dissolved in the drinking water
IPC: A61D7/00
Filed: 1988-10-29
Granted: 1990-02-22
Abstract: A glass pipe was developed for supplying water to laboratory rats whose dripping water loss is low and which can be easily controlled. In contrast to the previously conventional drinking systems it permits performance of drinking tests with quantitatively precise determination as well as meterable supply of test substances dissolved in the drinking water. Due to the fact that it is made from hard glass pipes it offers a high degree of breaking strength, is cost-effective and uncomplicated. In the region of the upper inflow orifice the outer pipe diameter (8 mm) was reduced by half (to 4 mm); a double, pipe-shaped glass insert secures the lower outflow end against unwanted dripping water losses. Approximately 5 cm above the outflow orifice the small pipe is bent at an angle of about 117 degrees and after cooling its inflow orifice is pushed into a rubber stopper. The connection of the novel drinking pipe with a commercially available 250 ml polyethylene bottle guarantees reliable supply of water to the animals.
Patent DE-3843478-C1 (DE)
Title: Electrical switching device having a contact cable
IPC: E05F15/44
Filed: 1988-12-23
Granted: 1990-02-08
Abstract: The known closing-edge safety devices operate with a component in the form of a flexible tube bending in order in consequence to achieve separation of the contact rollers. This closing-edge safety device would not react to a surface pressure acting over the entire length of the closing-edge safety device. In order to create contact cables which can also react to surface pressure, an elastic body is proposed in whose accommodation space the contact cable is arranged, the accommodation space having projections on its inside which project beyond its inner circumference, have a gap with respect to one another and thus produce the separation of the contact cable.

Granted: 1996-02-29
Abstract: Known processes for producing 2-hydroxy-4-methylthiobutyric acid (MHA) use a liquid-liquid extraction or a combined liquid/liquid and solid/liquid phase separation to isolate MHA from a reaction mixture produced by hydrolysing MMP-cyanhydrine. These processes are either costly or produce waste that is difficult to dispose of. These disadvantages are eliminated by isolating MHA by solid/liquid separation. The reaction mixture is evaporated until a MHA-containing salt residue with little or no residual water is obtained, the MHA-containing salt residue is treated with an organic solvent to produce a suspension, solid components are separated from the thus obtained suspension until a MHA-containing solution is obtained, the organic solvent is removed from the MHA-containing solution until a MHA residue is obtained and if required the MHA residue is then conditioned by water admixture. Besides high quality MHA, this process produces marketable crystalline ammonium sulphate and/or hydrogenated ammonium sulphate. This process is useful for producing feedstuff supplements.
