Patent DE-2358719-A1 (DE)
Title: Vacuum/pressure quality casting prodn. - by tiltable ladle and mould in sealed chamber at vacuum followed by pressure
Inventor: VITANOV JORDAN IVANOV
IPC: B22D23/00
Filed: 1973-11-26
Abstract: In a metal and metal alloy casting system, the ladle with the prepd. melt and the mould are moved into a common room of a sealed chamber which is then evaluated for 5 to 30 seconds. The ladle is then tilted to pour the metal in the mould. When the melt begins to solidify the vacuum is replaced by a pressure of 20-250 kgf/cm2 (50-120 kgf/cm2). This accelerates the casting operation. The castings produced have superior strength properties and a better crystal lattice without any micropores.

Title: Tank container accessory equipment - has folding feet allowing lorry platform to be driven underneath and pick it up
Inventor: WOLF GUENTER
IPC: B65D88/12
Filed: 1974-02-07
Abstract: The equipment is for use with a tank-container for road, rail, sea and air transport, allowing it to be set down from the carrying vehicle. Four or more support feet on the container frame are movable between the transit and setting-down position, and the container and frame rest on them on setting down, while in transit they are retracted so as not to increase the frame dimensions. The length of the feet, and their mounting points on the frame, are so selected as to allow transport by a standard lorry adapted to take interchangeable bodies, and which drives under the container and temporarily raises it by means of its hydraulically-operated body supporting surface, to allow the feet to be folded into retracted position.

Title: Packing case for skiing outfit - has slotted foam plastic location for retention of correct ski form
Inventor: MCLEOD WINFORD N
IPC: A63C11/02
Filed: 1974-04-23
Abstract: A transport case for skis has a rectangular cross section. It is made from two half shells which are linked by a hinge extending over its full length. Each half is filled with foamed plastic with location slots so that the skis are held in position with the correct amount of pre-stressing. Further recesses in the foamed plastic provide locations for ski sticks and boots. One half of the case has a tapered edge which engages in a matching groove in the opposite half thus producing a water tight seal. The stressing of the skis when being packed, provides the case with enough rigidity which allows a light weight case construction.

Title: Carbon dioxide absorption from gas with alkanolamine soln - in butanol, for low energy requirement in hydrogen purifcn for fuel cells
Inventor: HENKEL HANS-JOACHIM DR
IPC: B01D53/14
Filed: 1974-09-09
Abstract: In the absorptive removal of CO2 from bases using a soln. of an alkanolamine (I), BuOH is used as solvent for (I). (I) pref. is HOCH2CH2NH2. The process is used esp. in the prodn. of pure H2 from synthesis gas fro the operation of fuel elements with alkaline electrolytes; and also in the purificn. of natural gas etc. The process has a low energy requirement. Since BuOH has a lower surface tension than water, it can be sprayed very much more finely, giving a greater surface area and hence a higher absorption rate, which allows the use of a smaller absorber.

Title: Transportation of suspended rail vehicles - includes recognition of gaps at junction points for engagement of auxiliary carrying system
Inventor: ANKE DIETER DR ING
IPC: B61B13/08
Filed: 1974-09-24
Abstract: The suspended vehicle travels along the main rail elements until it reaches junction points where additional main rail elements and auxiliary rail elements are required to effect smooth transition without the rails moving as by signal-box points control. For this purpose sensors are installed. A collection of spacing sensors (100, 101, 110, 111) is assigned to each vehicle to reveal its position at any given moment by means of a logic arrangement. This is realised by decoding the binary signal patterns generated. This accurate positioning enables the vehicle to switch the auxiliary rail system in and out, on one or both sides, as it crosses the points.

Title: Extraction of samples from thin layer chromatography - having sample tubes with gas flow agitation
Inventor: MUELLER RUDOLF DIPL CHEM DR
IPC: G01N30/90
Filed: 1975-07-03
Abstract: Process for gentle mixing and/or extraction in sample tubes is carried out by gas flows. The mounting plate for the tubes is provided with several gas injection tubes, which are connected to each other and to a common feed branch by hoses or pipes. The mounting plate has >=2 guide rods joined to collars on the mounting frame. The gas flow is controlled by a valve, esp. a solenoid valve. The leaf sample from the thin layer chromatogram is mounted either vertically or inclined to vertical by means of a mounting clamp. The sample glasses can have grooves or slots in them for holding the leaf sample vertically or inclined to the vertical. For treating small samples in test tubes esp. leaf samples from thin layer chromatography. Generally the silica gel used for this is extracted with a solvent and the concn. determined by colorimetry. Agitation can cause the adsorption layer of the silica gel sheet to be dissolved and interfere with the determination. Filtration is not practical because of solvent and component losses. The system described allows simple and economic extraction which can be done on a routine basis.
