Title: Multi-stage water turbine of turbodrills
Inventor: BRUDNY-CELYADINOV SERGEI JULIE
IPC: F03B13/02
Filed: 1984-03-12
Abstract: In the multi-stage water turbine of turbodrills, each stage contains a stator (6) and a rotor (7) which have rims (8, 9) with flow passages (12, 13) and bosses (14, 15) which in each case carry blading (16, 17). There are stages in which blades (22, 23) of the blading are constructed with an angle  alpha  of curvature of the profile median line which is greater than the angle  beta  which is formed by a tangent (25) to this line at the outlet of the blading (16, 17) and by an axis S of the operating fluid flow. In the stage in which the rim (8 and/or 9) has such blades, it is constructed according to the invention with transfer passages (33, 34, 31, 32) which lie hydraulically parallel to the flow passage of the rim (8 and/or 9) and connect the space between this rim (8 and/or 9) and the rim (8 and/or 9) preceding in the flow direction of the operating fluid to the space between this preceding rim (8 and/or 9) and the following rim (8 and/or 9) to divert a portion of the operating fluid from the flow passage (12 and/or 13). The invention increases the service life of the turbine. <IMAGE>

Title: Drive head for video and audio cassettes
Inventor: KARGES FRANZ-PETER
IPC: G11B23/00
Filed: 1984-03-15
Abstract: This drive head has been developed for the purpose of simplifying repairs and the rewinding or winding on of video and audio cassettes of the Video 2000, VHS, Beta and compact cassette systems. It is very useful as a tool for manual rewinding and winding on in repairs and visual inspections of the tapes, and can also be used on tape-cleaning and rewinding machines. Since this for the first time provides the possibility of using one machine to work on the most popular video and audio tapes, the conclusion is that machine expenditure is reduced decisively (one machine instead of three or four). In addition, to my knowledge there has never before been a universal tool for the manual transporting of video and audio cassettes during repair and inspection work.

Title: Oxygen measuring probe
Inventor: DENZER ALWIN
IPC: G01N27/407
Filed: 1984-06-19
Abstract: An oxygen measuring probe comprises an oxygen ion-conducting solid electrolyte in the form of a tube closed on one side. This tube, on which the test gas acts on the outside and a reference gas acts on the inside, is provided both with an outer and an inner electrode. Said electrodes can be used to take off a voltage dependent on the oxygen partial pressure. The solid electrolyte is surrounded by a jacket tube which has at least one orifice providing communication between the test gas atmosphere and the solid electrolyte. Into said orifice a porous body preferably consisting of a ceramic composition is inserted, which is provided with a finely dispersed substance having a catalytic action with respect to hydrocarbon compounds, preferably with platinum. Said body expediently forms part of an exhaust gas catalyst used for the exhaust gases of internal combustion engines. Said body prevents the outer electrode from entering into chemical compounds with the test gas and thus prevents this electrode from being consumed. The finely dispersed, catalytically active substance is not attacked or consumed in the process.

Patent DE-3447903-A1 (DE)
Title: Electrical vacuum switch
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/18
Filed: 1984-12-31
Abstract: It is intended to produce a relatively homogeneous magnetic field in the switching chamber of a vacuum switch, the lines of force of which magnetic field run essentially parallel to the switching arc and thus hold said arc in the diffuse state. For this purpose, flat-cylindrical circular rings 14, 15, which surround the current-conductor bolts 12, 13 and consist of a material having a high magnetic permeability, are arranged on each of the two switching pieces 10, 11, behind the contact bodies 16, 17. The special feature of these rings is that their heights change in a complementary manner along their circumference; the increasing height of the ring on the one switching piece is thus located opposite the decreasing height of the ring on the other switching piece, and vice versa. The current flowing through the current-conductor bolts produces magnetic fluxes in the rings. As a result of the way in which the ring heights change in a complementary manner such that their sum is approximately constant, a relatively homogeneous stray flux is produced which, as intended, passes across the switching chamber, parallel to the switching arc. <IMAGE>

Title: Method of determining the behaviour of refractory material
Inventor: EVERTZ EGON
IPC: G01N33/38
Filed: 1986-02-15
Abstract: The invention relates to a method of testing refractory materials having oxidic and/or siliceous bodies, as exist in the system Al2O3-SiO2. The test should make possible a prediction of the behaviour of the refractory materials under operating conditions. While the test methods hitherto are very complicated and numerous, the invention is intended to reduce the effort of tests. The invention achieves this by the determination of the oxygen isotope distribution, which is familiar from geochemistry, of the refractory material in two states, of which one state is the as-delivered state or the state of a sample which has been found to be good in operation, while the second state is that after a test firing or otherwise that of a further delivery of the same type from the same manufacturer. This leads to the determination of  delta <18>O values, the difference between which is significant for the quality and thus the behaviour of the refractory bricks under operational use conditions.
