Title: Superplastically formed, diffusion bonded metal structure - obtd. using a stop-off compsn. comprising yttria and an organic vehicle
Inventor: WEISERT EDWARD DONALD
IPC: C10M103/06
Filed: 1980-01-18
Abstract: A structure formed of >=2 reactive metallic workpieces is obtd. by treating the workpieces at selected areas with a stop-off compsn. to prevent bonding at these areas, contacting the workpieces under coordinated temp-pressure time duration conditions to produce diffusion bonding at preselected areas, and applying gas press. between the contacting surfaces to cause breakthrough at the selected areas and superplastic forming of >=1 of the workpieces to stretch in excess of its original surface area. The stop-off compsn. comprises yttria of particle size >5 mu and an inert organic liq. vehicle comprising a binder capable of volatilising and leaving no organic residue at elevated temps. below the diffusion bonding temp. of the reactive metal. The vehicle is e.g. acrylic resin. The yttria is inert to reactive metals at the high diffusion bonding temps. and permits a relatively low break-through pressure-time prod. during superplastic forming, thereby preventing excessive strain or rupture of the metal through non-superplastic deformation.
Patent DE-3003580-A1 (DE)
Title: Drain valve for washing machines - closed by impeller of waste pump to prevent loss of wash liquor
Inventor: BOCHMANN HENRY
IPC: A47L15/42
Filed: 1980-02-01
Abstract: An outlet valve for household washing or washing-up machines has a small-dia. intake which can be firmly closed immediately behind the washing chamber, to prevent ingress of liquor into the drainage system before the washing process is completed. The closure is effected by the impeller of the waste pump which is pressed against the intake aperture by an external force acting on the other end of the shaft on which the impeller is mounted, which decentralises the rotor of the motor w.r.t. the stator. When the motor is switched on, electromagnetic forces centralise the rotor, thereby opening the valve. The wash liquor is fully utilised, with no wastage due to static pooling in the drainage system. The arrangement is cheap and simple to construct, and eliminates the need for extra conduits between washing chamber and waste pump.

Title: Wire joining to metallised surface - by heat and pressure using die with notched contacting face
Inventor: BAESSLER GERD
IPC: B23K3/047
Filed: 1980-05-07
Abstract: A device to join at least one wire by welding or soldering to a metallised surface, e.g. during the mfr. of capacitors, uses an indirectly heated contacting die which is applied under pressure. The contacting face of the die is shaped to suit the parts to be joined; it has, eg. a U-shaped groove if one wire is to be connected. A split electrode holder (10), sepd. by an insulating foil (12) 50-500 microns thick is joined by screws (18) to a contacting die (14). A notch-shaped groove (13) ensures that the wire (16), to be joined by embedding (17) in the metallised surface (15) on the substrate, is not damaged. The die is heated by high-frequency, heating elements or resistance heating. The preferred material for the die is an Ni-Cr-Co alloy with titanium and aluminium or a Cr-Ni-Si alloy. This embeds the wire or wires firmly in the metallised surface without damaging the fine wire by the contacting pressure.

Title: Monitor for brake condition on individual wheels - gives display of assessed state or defect warning signal on dashboard
Inventor: ANDRES RUDOLF
IPC: B60T17/22
Filed: 1980-05-13
Abstract: The braking torque applied to each wheel, for every application of the brakes, is assessed by an electronic processor. The torque is evaluated against applied pedal pressure and the result classified as 'brakes operational' or 'brakes defective'. If desired the latter classification can be subdivided into excessive pedal pressure required, and a condition where the pedal pressure is lower than normal for the braking effort obtained. The output from the processor can be displayed on a small screen on the vehicle dashboard. The screen can be divided into three zones, the centre one showing brakes normal and the adjacent ones indicating a defect. Alternatively, the information can be given by warning lamps. As all wheels are measured separately and compared against a set reference the result for each wheel can be displayed if so desired.

Patent DE-3102567-A1 (DE)
Title: Grinding or polishing paste
Inventor: OESZUET MUEMIN
IPC: C09G1/02
Filed: 1981-01-27
Abstract: The invention relates to a grinding or polishing paste for grinding or polishing metal surfaces, which is distributed on the metal surface to be ground or polished by means of a grinding or polishing tool. In such a grinding or polishing process it is a constant occurrence that the rolling movement of the grinding particles in the melt of the paste is prevented, which leads to scratches in the metal surface. To avoid this, the rolling movement of the grinding particles in the melt is improved by additionally incorporating in the melt uniformly dispersed powder particles, the hardness of the powder particles being less than the hardness of the grinding particles but greater than the hardness of the melt.
Patent DE-3104342-A1 (DE)
Title: Device for connecting two pipe ends in the case of a pipeline which is assembled from a multiplicity of individual pipeline parts
Inventor: WEINHOLD KARL DIPL ING
IPC: F16L27/12
Filed: 1981-02-07
Abstract: The invention relates to a device for connecting two pipe ends in the case of a pipeline which is assembled from a multiplicity of individual pipeline parts. It is frequently necessary to guide such a pipeline along a machine installation which is divided in its longitudinal direction into installation parts which can move with respect to one another. In this case, the length of a pipeline part will approximately correspond to that of an installation part, the connecting regions having to be constructed such that the pipe ends which are connected in them have the necessary relative mobility with respect to one another. In addition to the capability to pivot, this also includes a longitudinal displacement capability of the pipeline parts relative to one another. While previous devices produced these two movement functions within one sleeve part which, together with a plug-in part, produces the direct line connection between the pipe ends, according to the invention, the axial displacement capability is now intended to be limited to an extent which is required in the context of the capability to pivot within the sleeve part. The displacement movement which is furthermore required and is essentially larger is intended to be provided between an attachment part of the device and a retaining part which is connected to the respective part of the machine installation.
