Abstract: The inert gas, particularly He, is cooled in a heat exchanger as in DT 1751090. The most efficient type of heat exchanger is a liquid metal bath, particularly liquid Pb. Specifically the gas is circulated from the heat source to the heat exchanger and back to the heat source.
Patent DE-1928033-A1 (DE)
Title: Plastic skis with a malleable metal upper - edge of magnesium
Inventor: HAMMER HEINRICH
IPC: A63C5/12
Filed: 1969-06-02
Abstract: Plastic skins usually have an upper-edge of metal as well as an under-edge which protects the ski, however, whereas the average E module of the plastic is about 400,000 kg/cm2 the comparable value for the metal edges is much higher, this difference can badly effect the quality of the skiing. Therefore these skis are provided with an upper-edge of a material with an E-module of less than 500,000 kg/cm2 this material is magnesium, the upper edges are made in an angle or T shaped profile.

Abstract: Tags for attachment to mothers and infants are made by superposing on an oriented non-distensible foil of e.g. PVC a norrow Web of e.g. PVC which may be distensible and whose centre line coincides with the centre line of the first web, overlapping the edges of the second web with respective third webs of e.g. PVC whose other longitudinal edges coincide with the longitudinal edges of the first web, welding the latter edges and passing the web assembly under a device which thermowelds and partially cuts the web assembly along spaced transverse lines such that two oppositely disposed longitudinally extending sets of identifications tags are produced which are severable in pair along transverse lines of weakness. Each pair of tags is again severable into individual tabs each of which is provides with a pocket defined by the overlapping edges between the second and third webs.
Patent DE-1943067-A1 (DE)
Title: Cooling tower secondary condensation - prevention
Inventor: MOSKAU GERHARD
IPC: F28C1/14
Filed: 1969-08-23
Abstract: Reduction of the secondary condensation in the surroundings of cooling towers is ensured by feeding outer air in the upstream of the tower for mixing with the exhaust. Instead of the outside air, another gas may be used when its enthalpy and/or water content are smaller than the corresponding values of the cooling tower exhaust air. The method also ensures the recovery of evaporation water, and a reduction in icing at the air inlet, as well as the control of the cooling tower output.

Patent DE-2127295-A1 (DE)
Title: Perforated plastic tubes - with slits opened by drawing
IPC: B29C48/30
Filed: 1971-06-02
Abstract: A perforated, weldless plastic plane tube having slits, cuts or lines of weakness is drawn so that the edges of the slits are separated so as to form orifices. The slits may be parallel, perpendicular or at an angle to the axis of the tube, as may the direction of drawing. The slits are formed during extrusion by cutting, and so that there ae no residual stresses in the tube. Opening of the slits may be by a template, pref. of larger diameter than the tube, or of increasing diameter. The slits may be formed by a tool with knives its inner surface which is given an alternating motion in the extruder head. The process gives tubes of constant wall thickness and the drawing of the tube increases its mechanical properties.

Title: Coating articles with plastics in a fluidised - bed
Inventor: BLACK JOHN W
IPC: B05C19/02
Filed: 1971-07-10
Abstract: Articles, e.g. wire rod shelving, are fed on a first endless chain conveyor into a first oven mounted above a fluidised bed of plastics material.

The third conveyor feeds the articles through the fluidised bed and onto a fourth chain conveyor which feeds the articles through a second-oven above the fluidised bed and subsequently through coolant in a tank disposed adjacent the fourth chain conveyor. A control system controls and synchronises the operation of the conveyors.
