Title: Heated and drawn inter. prod. for supercondddducting coooomponents - contg. copper tubes contg. an inner concentric tube of niobium
Inventor: MAIER RICHARD DR
IPC: H01B12/12
Filed: 1973-07-03
Abstract: A Nb tube is inserted in a Cu tube and the assembly is heated in a vacuum chamber to below the m.pt. of the Cu but high enough to form a diffusion cpds., pref. at 900-1050 degrees C. The Nb tube is then forced outwards while cooling to 200-350 degrees C. so that it meets the Cu, and the assembly is reheated to form the diffusion cpd., pref. for 10-110 min. at 900-1050 degrees C. An intimate bond is thus formed between the two metals, the Cu being able to carry (part of) the current if the Nb reverts from the superconducting to the normal state at the temp. of liq. helium. Prod. is used as an inter. prod. for mfr. of resonators, particle accelerators and superconducting cables.
Patent DE-2347857-A1 (DE)
Title: Composite press.-die castings of light metal - plus wear-resistant inner layer transferred from die-core
Inventor: MEYER-RAESSLER ERICH DIPL ING
IPC: C25D1/10
Filed: 1973-09-22
Abstract: A process where the inner layer required is first deposited on the core used in the die and, after casting, a temp. drop is produced between the cast part and the core so that the layer is detached from the core and is bonded to the cast part. The novelty is that the wear-resistant layer is deposited on the core by electroplating and, during the final stage of deposition, the current density is raised so that a very rough surface is obtd. on the deposit. Pref. conditions include the use of a final current density of min. 25% higher than that at which a smooth deposit is obtd., the surface can be further roughened by etching, the use of a shaped anode with indentations on its surface, or a perforated mask between anode and core; and the core can be coated with a sepg. agent prior to plating i.e. to reduce the adhesion of the layer. Used to obtain e.g. nickel layers contg. SiC particles on the inside faces of cylinders on conventional internal combustion engines and combustion housings on rotary i.e. epitrochoidal engine. The process avoids the slowness, and porosity, obtd. by spraying.

Title: Heat-insulating filler gases - having lower thermal conductivity coefft than air and used e.g. in double glazing
Inventor: BROSE WERNER JOHANN HEINRICH
IPC: E06B3/67
Filed: 1974-08-15
Abstract: Pores or cavities of building materials or components are filled with heat-insulating filler gases which have a smaller thermal conductivity coefft. lambda than air, i.e. 0.0210 kcal/m.Hr. degrees C. The filler gas is e.g. ethylene oxide, propylene buta-1,3-diene, 1,3-dimethylbenzene.
