Title: Electromotor has condensed water removed from inside housing - by porous wick that soaks up water and deposits it outside
Inventor: LARSEN HANS ANDREAS
IPC: H02K5/10
Filed: 1975-02-12
Abstract: The electric motor has a porous wick inside its housing to remove condensed water. The wick passes through the bottom of the housing where it soaks up the condensed water, transfers it to the outside of the housing and allows it to drip harmlessly from its dangling end. The wick can be built through the housing almost anywhere and, because of its flexibility, can be led to the required spot inside the housing. This avoids the disadvantages of porous plugs which can only be fitted to the housing in places that may not be where the most water is.

Title: Sensor for proximity fuse of antiaircraft projectile - has variable elevation angle to ensure high fragment density projection
Inventor: HELD MANFRED DIPL PHYS DR
IPC: F42C13/02
Filed: 1975-06-19
Abstract: The sensor for a proximity fuse for detonating a projectile and spreading fragments against an aerial target has variable elevation angle. This angle can be varied relative to the longitudinal axis of the effective explosive charge. The projectile disperses the fragments in a region with limited angl efor ensuring high fragment density. This increases the hit and destruction probability of aerial target. The elevation angle of the sensor is varied in relation to the interception velocity between the target and the projectile, and the average scattering speed of the fragments produced. The elevation angle is determined by the elevation angle of the main effective direction of the fragments relative to the projectile longitudinal axis.

Title: Solid wall centrifuge bowl - in which tug end plates form a lip and the wall has smaller diameter
Inventor: PAUSE KURT
IPC: B04B7/08
Filed: 1976-03-04
Abstract: Solid bowl centrifuge has base and top and plates of uniform thickness. The outer edges are the same. The contracted offset of the jacket corresponds to 1-15 times the jacket projection at highest loading plus the projection of the original end plate. In the contracted form the bowl is stress relieved by an annealing process. The cross section of the base plate is so arranged that the moment of inertia of the plate corresponds to an adequate disc of uniform thickness. The area of cross section is however only half or less than this adequate plate. This plate is centred on the hub. This however operates from the nature of the shape and independent of the state of deformation of both parts. Esp. for use in sepg. crude sugar residues at speeds of 1500 rpm. in batch centrifuges. The system allows the bowl to use a raw material of the same thickness as the final prod.; the end plate has a moment of inertia of a plate of larger dia.; the bowl dia. is smaller than that of the end plates; and the base plate fits into a slot on the hub.

Title: Diazonium salt test strips for detecting bilirubin in urine - contain buffer selected to suppress interference
Inventor: HIRSCH WOLFGANG DR
IPC: G01N33/72
Filed: 1976-05-22
Abstract: Test strips for detecting bilirubin in urine comprise an absorbent carrier impregnated with one or more diazonium cpds., buffer substances and optional additives such as stabilisers, optical brighteners and/or thickeners. The improvement lies in the use of a buffer with a pH such that the reaction of the diazonium cpd. with natural constituents of urine is suppressed sufficiently not to interfere with the colour reaction with bilirubin. The strips can be used in the diagnosis of liver and biliary disorders. Interference by indoxylacetic acid and indoxyl sulphate is suppressed, since many diazonium salts have a pH range in which these substances only give at most a pale yellow colour reaction. In an example, 2-trifluoromethyl-benzenediazonium tetrafluoroborate is used at pH 3.5.
