Patent DE-2022419-A1 (DE)
Title: Porous granules and shaped articles from mineral powders
Inventor: JOSEF KRAUSE HEINZ
IPC: C04B38/00
Filed: 1970-05-08
Abstract: Porous granules or shaped articles are produced from mineral powders, such as clay or combustion duct, by (a) mixing the powder with water to form a deformable paste, (b) adding a foam mass to the paste, and (c) hardening the mixture by baking or adding a hydraulic binder. The density and strength of the porous granules or articles can be controlled accurately. The granules become consolidated during baking, so that better one can be made of a rotating furnace during baking. Articles such as tiles can be produced cheaply. The viscosity of the paste is pref. lowered by adding a liquefying agent, e.g. an electrolyte, pref. sodium carbonate or sodium silicate.

When the container is empty both machines are switched off at the same time by the current supervising device.
Patent DE-2361564-A1 (DE)
Title: Soldering difficult metals to copper - esp tungsten for applications on semiconductor components
Inventor: WAHL GEORG DIPL PHYS DR
IPC: B23K1/20
Filed: 1973-12-11
Abstract: This is a process for joining two metals (I, II) where >=1 metal (II) is unsolderable or can only be soldered with difficulty. The surfaces of both metals or at least metal (II) is roughened to form open pores and projections and a thin, intermediate layer of solder is deposited in the pores, the layer being so thin that the rough surface remains virtually unaltered; the "wettable" layer of solder bonded mechanically to metal (II) is then used for a soldered joint. The depth of roughness should be min. 1 mu and can be achieved by depositing metal (II) from the gas phase onto a substrate of the same material, i.e. metal (II); alternatively, the roughness may be obtd. by plasma spraying. The intermediate layer can be obtd. by deposition from the gas phase and the pref. joint is W to Cu, where W is deposited onto W from the gas phase and Cu 1-5 mu thick applied to the rough surface before soft-soldering. The process makes possible the formation of joints hitherto regarded as impossible, e.g. for use in microelectronics.

Title: Starting aid for single-phase sync. motor - has helical spring linking rotor for momentum gain before full loading
Inventor: SCHEMMANN HUGO DIPL ING DR
IPC: H02K7/118
Filed: 1974-02-14
Abstract: The starting aid, for a single-phase synchronous motor with a permanently magnetic rotor, consists of a flat spring wound into a helix around a former, enclosed in an elastic sleeve and linking the motor's load with the rotor. The load and the rotor are otherwise not connected together. The shaft passes axially through the spring's former. When the motor is started the helical spring allows the rotor time to gain momentum before the full inertia of the load is experienced. This initial momentum allows greater initial turning moments to be produced compared to motors whose rotors are rigidly linked to their loads.
