Abstract: Crosslinking agent used in positive resist is an N-(N'-2-hydroxyethyl)-aminoethyl-amide cpd. (I) of formula R-CO-NH-CH2CH2-NH(CH2)2OH (in which R is alkyl). Positive resist is used to make negative of a mask by exposing a sealed layer of the resist contg.

Process is specified for use in prodn. of lift-off masks, esp. for use in metallisation. It is relatively simple, and suitable for large scale operation. Good resolution is obtd. and the negative is very true to the original, with very small tolerances and very few flaws. (I), which is the hydrolysis prod. of 1-hydroxyethyl-2-alkylimidazoline (II), gives better results than (II) itself and also promotes adhesion of the resist to the substrate.

Title: Bonding insulation to conductors after extrusion - involves heating surface layers of insulation with oxygen enriched flame
Inventor: DAENEKAS FRANZ
IPC: B29C48/06
Filed: 1979-08-23
Abstract: The insulation is extruded onto the conductor with a binding material to form a watertight close bonded seal to the conductor. The insulation is extruded onto the conductor and afterwards is given an activating oxygen heat treatment. The e.g. co-polymer ethylene insulation material with close binding aggregate is fed into the cone (1) hopper of the extruder (2) for mixing. The binding silene and ethylene insulation materials are fed through the extruder (3) into an applicator section (4). The conductor (6) is fed past the extruder nozzle (5) so that the insulator is applied. After extrusion the temperature of the outer insulant is raised by 120 to 180 deg.C by an oxygen enriched flame oven which enhances the outer oxidation of the insulator. The temp. is above the insulator extrusion and m.pt. level. The final temp. of the outer is 250 to 350 deg.C when it leaves the oven zone (7).

Title: Solar cell battery charging circuit - includes shunt with parallel sets of cells, one in series with bimetal switch
Inventor: KOETHE HANS KURT DR ING
IPC: H02J7/35
Filed: 1980-03-12
Abstract: The charging circuit uses photo voltaic converters such as solar cells and includes two sets of cells (1,2) in parallel, with one set (2) in series with a thermally operated bimetallic strip (5). These are in series with a blocking diode (3) connected to the accumulator (4). Also in parallel with the cells is a shunt controller (9). This has one path formed by a shunt resistance (8) in series with a transistor (7), preceding the diode and a parallel path formed by the controller (6), following the diode. The shunt controller bypasses current from the battery as it becomes charged, and the temperature of the shunt resistance (8) increases as the current flow through it increases. This temperature increase operates the bimetallic switch (5) so that the current flow in the circuit is regulated.
