Title: Sand moulding machine
Inventor: WOSNITZA WERNER
IPC: B22C11/04
Filed: 1995-12-07
Abstract: Sand moulding machine consists of a downwardly movable pressing head (2) which compacts the sand at the same time as it pushes down the filling frame (KFR), mould box (FK) and counter pressing frame (GPR). The force applied is such that the bottom edge of the frame (FK) is equal with the support surface. After pressing, the press and mould box are pulled upwardly by arms (20a,20b), and spring devices (10,11) push the counter press frame back into its starting position. The spring pressure (10,11) is hydraulic, gas pressure or mechanical spring pressure. The model is held on the support by vacuum pressure and air nozzles in the model can be activated after pressing to facilitate the easy movement of the model from the sand moulding.
Patent DE-19546614-A1 (DE)
Inventor: QUADAKKERS WILLEM J
IPC: H01M8/0208
Filed: 1995-12-13
Abstract: The invention concerns a chromium-oxide-forming alloy with reactive elements added to the alloy and with reactive elements additionally implanted in the alloy surface or applied thereto. The term "reactive elements" includes chemical elements such as, for example, Y, Ce, Hf and La which have greater affinity for oxygen than does chromium. The material is intended for use at high temperatures since it is more corrosion-resistant than prior art materials. This alloy can in particular be used for bipolar plates for high-temperature fuel cells.

Patent DE-19613351-A1 (DE)
Title: Shaft-nave connection
IPC: F16D1/08
Filed: 1996-04-03
Abstract: The shaft-nave connection is achieved through the use of deforming elastic elements between the shaft and nave.

Patent DE-19614842-A1 (DE)
Title: X=ray diagnostic device with filter arrangement
Inventor: SEISL JOHANN DIPL ING
IPC: H05G1/26
Filed: 1996-04-15
Abstract: The filter arrangement includes at least two different filters which can be brought into the beam input of the x-ray generator. The filters are moved automatically depending on the load of the x-ray tube. The filter currently being used can be displayed. If the user has a voltage plateau of 63 kV and a filter with a thickness of 0.2 mm is selected, that filter is used until the peak load of the x-ray tube is reached. Once the peak is reached, the next filter with a smaller thickness is automatically selected. The contrast is thereby reduced.

Title: X=ray computer tomograph for human body investigation
Inventor: HELL ERICH DR
IPC: A61B6/03
Filed: 1996-05-09
Abstract: The x-ray computer tomograph includes an x-ray generator with a long anode. X-rays are deflected by a variable magnetic field so that a vol. of the object under investigation (e.g. a patient) can be sampled. The electron beam from the x-ray source is deflected by 10 to 180 deg.  The focal point is shifted in sync with a primary beam shutter which forms a pyramid-shaped x-ray bundle so that the detector receives all of the x-radiation emitted from the patient. The detector is composed of a matrix of detector elements so that the vol. can be sampled without moving the patient.

Patent DE-19628102-A1 (DE)
Inventor: MIELSCH GOETZ
IPC: C23C14/28
Filed: 1996-07-12
Abstract: The invention relates to a device, in particular for a laser-induced vacuum arc discharge evaporator for depositing of multiple layers with a high level of purity and high deposition rates on large-area components. According to the invention, the material source for the coating material is in a source chamber which can be evacuated and can be separated in a vacuum-tight manner from the actual coating chamber in which the substrate to be coated is located. The evaporator can, in particular, be used for deposition of amorphous carbon layers which are hydrogen-free and superhard and/or which contain hydrogen, in conjunction with high-purity metal layers or for the reactive plasma-enhanced deposition of, for example, oxidic, carbide, nitride hard material layers or ceramic layers or a combination thereof. The corresponding plasma sources can be flange-mounted on any suitable coating chambers and, consequently, also combined with conventional coating processes, for example magnetron sputtering.

Patent DE-19639084-A1 (DE)
Inventor: HENIG HANS
IPC: C25D21/18
Filed: 1996-09-24
Abstract: In the direct recovery of residual quantities of an aqueous solution adhering to pourable mass parts following an electrolytic and/or chemical surface treatment on the parts the parts are carried in a perforated immersion barrel 2 supported on a movable carriage 6 of a barrel treatment installation. A compressed-air chamber is provided on the carriage, into which the barrel is moved, the chamber being provided with a compressed air source to cause a current of air to flow transversely through the chamber. The compressed-air chamber essentially comprises a horizontal, upwardly cylindrically convex upper half-shell 7 which is fixed on the carriage and which encompasses in a substantially air-tight manner the upper half of the immersion barrel when the barrel has been positioned within the chamber, and a pair of horizontal, lateral, lower, outwardly cylindrically convex quarter-shells 8 which are capable of movement towards and away from one another. When moved together, the quarter-shells encompass the lower half of the immersion barrel in a substantially air-tight manner, except that the two quarter-shells leave open a relatively narrow longitudinal slot between their two lowermost long edges. The current of air passes into the chamber and after passing through the barrel and over its contents, leaves the chamber downwardly, entraining any dragged-out solution in the air stream. Water may be injected into the air stream, to assist removal from the parts of the dragged-out solution.

Patent DE-19648691-A1 (DE)
Title: Electrodynamic field energy production in chemo-electrical converter
Inventor: RADEBOLD REINHART DR
IPC: H01M8/06
Filed: 1996-11-18
Abstract: Conversion of the free enthalpy stored in hydrogen-containing materials (especially glucose and other chemical 2 H sources) together with atmospheric oxygen into the energy of an electrodynamic field is effected in a chemo-electrical converter (i.e. fuel cell) based on the reaction 2H + O ?> H2O. The 2-stage reaction uses the free reaction enthalpy of both stages. The free reaction enthalpy of the first stage, yielding hydrogen peroxide and subsequently the actual acceptor O, is released by reaction of the O2 with hydrogen-containing compounds (preferably of halogens or pseudo-halogens) and transferred via the reaction product(s) to the reaction sequence for breaking the glucose into (4H + CO2) pairs. The reaction enthalpy of the second stage (based on H2O2) is used for the chemo-electrical reaction. The actual acceptor O is removed from the H2O2 (preferably via a carrier based on acids capable of peroxide bonding) and transferred to the positive electrode of the converter.
