Patent DE-2931106-A1 (DE)
Title: Recovering premium oil from slurry produced by hydrogenation of coal - by countercurrent contact with a non-polar solvent in a column
Inventor: MOLL NORMAN GLENN
IPC: C10G1/00
Filed: 1979-07-31
Abstract: A feed slurry produced from a solid carbonaceous fuel (esp. coal) is sepd. into a premium liq. oil fraction (I) and fire solids and polar liquids -contg. fraction (II) by contact with a non-polar liq. solvent, chosen from (a) 5-9C alicyclic hydrocarbons, (b) 5-9C aliphatic hydrocarbons and (c) a naphthenic or paraffinic fraction of a coal liquefaction prod. contg. 10wt.% aromatic cpds. in a vertical column having a lower collection zone whose wall temp. is >=20 degrees C higher than that of the wall defining a contacting zone. The column has an upper setting zone which, along with the contacting zone, is operated at 100-250 degrees C and at a pressure sufficient to keep the feed and the solven liq. but 450 psi. The feed is introduced at the top and the solvent at the bottom of the contacting zone, the solvent:feed wt. ratio being >=0.5:1 (pref. 0.6-5:1). The solvent passes up the column, the feed passing down, and is in intimate contact with the feed and extracts (I) from it. (I) is then recovered as an overflow from the settling zone and (II) is recovered as a viscous slurry underflow from the collection zone. A solids-free overflow of premium oil is recovered from the column. Unconverter fuel, polar molecules rich in heteroatoms (O, N, S) etc. are also removed.

Title: Removing gold from silicon surfaces esp. in semiconductor mfr. - using iodine soln. contg. ammonium iodide and fluoride, which dissolves gold but not silicon
Inventor: KUISL MAX DR RER NAT
IPC: C22B7/00
Filed: 1979-08-30
Abstract: The gold is dissolved by using an aq. soln. contg. at least 5-10 g/l elementary iodine, 5-10 g/l iodide, pref. ammonium iodide, and 10-30 g/l fluoride, pref. ammonium fluoride; and the pH as the soln. is pref. adjusted to 6-7. Gold is a highly undesirable impurity in semiconductor mfr., esp. when using very large scale integration, and the invention provides a soln. which dissolves gold while hardly attacking the silicon.
Patent DE-2939613-A1 (DE)
Title: Insulating metal double skinned hangar profile roof - has upper skin sliding above lower one to compensate for heat expansion
IPC: E04D3/36
Filed: 1979-09-29
Abstract: Spacing components separate an upper and a lower shell made of profile sheet metal plates, to provide a space for heat and/or sound insulation and a ventilation area, in a profile roof for laying on a substructure, esp. in a hangar- type building. The upper shell (4) is mounted on the lower one (1) so as to be displaceable, providing compensation for expansion effects lengthways and crossways. Use can be made of spaced sliding connections (10), with play in the upper profiles lengthways and crossways directions, to limit the upper shells movement and to support it on the lower shell. There is pref. greater play lengthways. This successively combats heat expansion and shrinkage, and provides adequate stability under wind loading.

Title: Jet-dyeing machine for endless-rope fabric - having variable capacity dwell chamber with wall of adjustable curvature
Inventor: FRIEDRICHS KURT ING GRAD
IPC: D06B3/28
Filed: 1979-11-14
Abstract: A machine for the wet-treatment, partic. dyeing of fabric in endless-rope form has a cylindrical vessel enclosing an arc-shaped dwell chamber, at the inlet end of which is a jet-tube for circulating the fabric through the chamber. The inner arcuate wall of the chamber is formed of at least two overlapping plates whose positions can be altered to vary the cross-sectional area of the dwell chamber. The plates are adjusted by means of levers which are connected to handwheels outside the vessel. This construction allows a wide variety of fabrics to be treated under optimum conditions by matching the capacity of the dwell chamber to the type of fabric being treated - from low capacity for lightweight, sensitive fabrics to a high capacity for heavyweight and bulky fabrics.

Title: Magnetic securing of thermometer to steel surface - has holder for permanent magnet attached to housing with shaft tube and centering surface
Inventor: KACHEL PHILIPP
IPC: G01K1/12
Filed: 1980-05-13
Abstract: The magnetic securing system is for a heat measuring instrument attached to a steel surface. The measuring instrument consists of an indicator thermometer for registering high temperatures. The magnet is mounted on a holder and can be replaced. The holder is made from a ferromagnetic material.

Title: Space-filling between components - involves insertion of foaming and setting material after shutting off on one side
Inventor: KOLBE KLAUS
IPC: E06B3/267
Filed: 1980-09-25
Abstract: The method fills the spaces between body components such as profiled rails, these spaces being interrupted at regular intervals by clamping pieces securing the components together. The spaces are shut off along one side by engagement of a strip of material with the two components outside the clamping pieces, after which the outlets of a filling machine are positioned above the spaces, at intervals equal to the clamping piece centre distance. A predetermined quantity of material, foaming and setting on contact with air, is then delivered into each space, and a further strip of material is then engaged with the components clear of the clamping pieces, sealing the spaces off.

Title: Compression type heating system - has motor-driven compressor delivering ambient air to heat exchanger
Inventor: JAKOB LUDWIG ING GRAD
IPC: F24J3/00
Filed: 1980-11-29
Abstract: The heating system comprises a compressor (B) driven by a motor (A), converting the ambient air from a first (1) to a second (2) state, raising the temp. in the process. Heat is extracted from the air in the second state by a heat exchanger (C), and delivered to the heating circuit, the air being converted to a third state (3), in which it can be used to drive a motor (D), which helps drive the compressor via a clutch or gearbox. The heat losses from the motor and the compressor can be absorbed by the ambient air, which is drawn into the compressor.

Title: Motor car brake valve
Inventor: STUMPE WERNER
IPC: B60T8/18
Filed: 1981-01-22
Abstract: A motor car brake valve (1) is proposed, which is equipped with a second control device (7), operable by its pedal (4), for a so-called "third" vehicle brake. In addition to mechanical operation from the brake valve this control device (7) can also be influenced by a pressure which may be either constant or variable. In the latter case the pressure is varied, preferably as a function of the load. The control device (7) may be designed as a pressure control device or as a relay valve device. By special means a constant or a variable rate of the inlet pressure can be contained in the outlet pressure. The brake valve is particularly suitable for the additional control of a retarder for heavy commercial vehicles. <IMAGE>
