Title: Coating conductors with non-metallic powder applied by electrophoresi
IPC: C25D15/00
Filed: 1970-03-13
Abstract: In process for applying adherent crack-free hard wear-resistant layers of powdered non-metallic materials, such as carbides, nitrides, borides, silicides and oxides of metals such as W, Mo, Ta, Nb, Ti, Zr; carbides and oxides of Si and B, diamond powder and Al2O3, by electrophoresis on to an electrically conductive support of desired shape, the electrophoretically applied layer is anchored by electrodepositing a metal or metal alloy first on the support and then in the pores of the powder layer. Before start of electrodeposition the pores of the powder layer are kept free from air or gas by means of left over suspension agent of electrophoresis or advantageously by means of electrolyte introduced into the pores by means of a wetting agent or vacuum and if necessary pressure. For applying porous layers, the powdered materials are provided, before electrophoretic separation, with a covering layer, advantageously an organic layer for example a lacquer or paraffin soluble in a solvent, which is removed after electroplating, advantageously by dissolving with a solvent.

Title: Injection and blow moulding
IPC: B29C49/64
Filed: 1971-02-08
Abstract: A method for making hollow objects from hot deformable plastic such as PVC, using an injection-moulded parison which is then blown in a blow mould to the finished size, and which is transported with its longitudinal axis horizontal from one position to the next, is carried out by influencing the temp. of the premoulding or parison in such a way as to compensate it for the subsequent uneven cooling during this transport. Specif., the parison is unequally cooled in the injection mould. In the preferred appts., coolant is introduced opposite the part of the parison which will become uppermost during transport, the coolant leaving at approximately half height.
Patent DE-2118707-A1 (DE)
Title: Liquid separator - for sepn of liquids from gases comprising cylindrical filter in permeable elastic tube
IPC: B01D53/26
Filed: 1971-04-17
Abstract: Appts. consists of a hollow cylindrical filter body surrounded by a macroporous tube of elastic permeable material e.g. foam, and connected to a hemispherical liquid reservoir at the bottom. The gas contg. water or oil enters and flows in a radial direction through the filter medium on to the side of the macroporous tube. The purified gas goes through the circular holes at the bottom to the outlet. The filtrate liquid drops coalesce to form bigger drops and are thrown out through the radial flow action of the gas and go down through gravity and interfacial tension. A conical unit in the path of the gas minimizes the turbulence.

Title: Self-extinguishing polyamide compsns - contg oligomeric or polymeric halogenated cpds,remaining fire-resistant after exposure
Inventor: TACKE PETER DR
IPC: C08L77/00
Filed: 1972-01-27
Abstract: Permanently self-extinguishing polyamide moulding compsns. contain 6-30 wt.% of an oligomeric or polymeric halogenated cpd. with 10-80 wt.% halogen content, 0-25 wt.% of >=1 metal cpd. with a synergistic action and 0-50 wt.% of a filler. The self-extinguishing property is retained on prolonged exposure to increased temp. The halogenated additives are not toxic. there is only a slight adverse effect on the mechanical props, even with the oligomeric additives. A standard degree of flame-resistance can be achieved with a lower halogen content when using an additive of relatively high mol. wt. The compsns. are esp. suitable for injection casting. The incorporation of the halogenated additive in the polyamide compsn. by means of an extruder is claimed.

It may consist of several parallel slit diaphragms whose lengths are independently adjustable. In order to obtain a symmetrical test curve, the diaphragm aperture form corresponds to the actual distribution of the tested sample, or to a standard distribution, or to a function derive from both by unfolding and/or folding with symmetrical curves. It may consist of several partial apertures behind each other and movable relative to each other. Only two partial apertures may be used, with the distance between their axes adjustable to the distance of the doublet during X-ray diffraction patterns recording.

Title: Retarded action furniture stay arm - has piston and cylinder unit with throttled by-pass in cylinder body
Inventor: HAENISCH ROBERT
IPC: E05F3/02

Abstract: The arrangement is intended to prevent a sudden sagging down of folding tops on furniture. The cylinder end of the assembly is fitted in a pivoting manner inside the furniture body, the other part i.e. the piston rod to the folding top. The retarding action is limited to the folding down movement of the top by the throttling action of a narrow channel in the piston allowing a restricted escape of air from bottom to the top of the cylinder. Movement in the opposite direction is facilitated by a conventiently shaped lip section of the piston seal.

Title: Water-cooled electric furnace cable - has strain-removing, flexible riser tube between transformer and furnace on latter tilting
Inventor: GOODMAN DANIEL J
IPC: H01B9/00

Title: Air heating with heat pump unit - utilising expansion, removal of condensed natural moisture content, and recompression
Inventor: BSCHORR OSKAR DR RER NAT
IPC: F24H3/02
Filed: 1973-11-26
Abstract: Air is heated by heat pump, for space heating, drying plant, or fog dispersal; the air with a natural moisture content is expanded, and the condensate water or ice formed is sepd. from it, then air then being compressed back to the initial press. Preferably the expansion of the air is in a convergent nozzle part and the compression in a divergent diffusor, while a fan maintains the flow and supplied the process work. The expansion may be in a turbine or motor and compression in a fan, with both these machines fixed on a common shaft through which the power is also supplied. No heat transitions occur through fixed partitions, and the air itself serves as a heat reservoir.
