Patent DE-3048391-A1 (DE)
Title: Doser for molten metal, for filling foundry moulds or dies - where tilting scoop is located on pair of swivel arms moved between crucible and casting machine
Inventor: DOBE WILFRIED ING GRAD
IPC: B22D39/02
Filed: 1980-12-22
Abstract: This is an addn. to 2804381, which described a doser using a scoop to lift molten metal out of a melt with a variable height in a crucible. The scoop is then moved so it is above a mould or die in a casting machine. The novelty in the present invention is that the scoop is located on the bottom end of an arm(1) provided with a motor for tilting the scoop. Arm(1) is located on one end of a lever (II), which is swivelled by another motor to move the scoop between the crucible and the casting machine. A chain drive is used to keep arm(I) at a desired angle while arm(II) is being swivelled; and a second chain drive is used to tilt the scoop. The swivel unit described in the main patent was complicated and unreliable; these disadvantages are eliminated by the present invention.

Title: Butt welding of steel pipes with internal polymer lining - which is removed from pipe bores near joint, and replaced by polymer bush
Inventor: MATTHIAE SIEGFRIED
IPC: F16L58/18
Filed: 1980-12-30
Abstract: The lining is removed from both pipe ends to be joined together, for a distance (d) which depends on the welding process. The two pipe ends are then aligned, and a bush, made of the same polymer as the pipe lining, and provided with a heat sink, is placed inside the two pipes to bridge over the two bare zones. When the two pipes are welded together, the temp. produced at the two points which are each located at distance (d) from the butt weld in the steel causes the bush to weld with the lining in each pipe. An economic process, which can be employed on a site; and the process time is not significantly greater than that required for the butt welding of unlined steel pipes.

Patent DE-3123280-A1 (DE)
Title: Copier
Inventor: NISHIMOTO KANICHI
IPC: G03B27/80
Filed: 1981-06-12
Abstract: The invention relates to an improved copier for exposing a colour copier paper and for producing copies. The copying process is carried out with a specific colour balance which is obtained by means of an intersection filter arrangement consisting of three intersection filters, namely a yellow filter, magenta filter and cyan filter, each of which is actuated by signals which are supplied by numerous colour photosensors. During the copying process, two light-beam flux reducing filters which are contained in the intersection filter arrangement are activated in an operating state in which the intensity of a light beam coming up from a light source is previously amplified to a specific value such that it corresponds to a negative colour film which has been overexposed during a photographic exposure. One of the light-beam flux reducing filters is moved into a light beam channel before a closure shutter is opened if it proves that the negative colour film has been normally exposed whilst the other light-beam flux reducing filter is moved into the light beam channel at the same time as the first if it proves that the negative colour film has been underexposed. As a result, rapid copying with minimum fluctuation of copying time is ensured and an extremely good colour balance is maintained irrespective of whether the negative colour film has been overexposed or underexposed during the photographic exposure.

Patent DE-3131931-A1 (DE)
Title: Method for superplastic forming
Inventor: HAMILTON C HOWARD
IPC: B21D26/055
Filed: 1981-08-12
Abstract: The invention provides a method for the elimination of internal cavities in superplastically deformed or superplastically deforming components. Use is made of a workpiece made from a material capable of being deformed superplastically. This workpiece is inserted into a die, in particular opposite a forming surface. The workpiece is heated to the superplastic forming temperature and both sides of the workpiece are subjected to pressure. This pressure is sufficient to prevent the formation of cavities and pores. The pressure on the side of the die furthest away from the forming surface is then increased, deforming the material superplastically and causing it to bear against the forming surface. In a second embodiment, pressurisation is performed after the workpiece has been formed, either by maintaining the pressure and compressing the material between the forming pressure and the reaction force of the die or by pressurizing both sides of the component with a pressure medium, in which case the cavities are eliminated by a process of plastic deformation and diffusion.

Patent DE-3146431-A1 (DE)
Inventor: OPPITZ PETER
IPC: D06B15/02
Filed: 1981-11-24
Abstract: The very economical padding methods for applying liquid treatment agents and which have largely become established for flat-lying material are also interesting for dyeing and finishing tubular textile material. In the latter case, the use of this technique is however opposed by the finding that on impregnating circular-knitted goods on a pad mangle the squeeze edges are marked on both sides of the tube, which gives rise, for example, to undesirable color differences. According to the invention, this adverse phenomenon and the problems arising therefrom can be avoided if, through maintaining a relatively high liquor pick-up by the textile material and through mechanical shifting of the edges, the liquor is enabled to level out any unevenness produced on squeezing.

Patent DE-3151700-A1 (DE)
Title: Method for facilitating repair work on a valve timing mechanism of an internal combustion engine with overhead valves and a tool for carrying out the method
Inventor: BIELING ALFONS
IPC: F02B1/04
Filed: 1981-12-29
Abstract: The invention relates to a method for facilitating repair work on a valve timing mechanism of an internal combustion engine with overhead valves. The method according to the invention is characterised in that compressed air is injected into one cylinder space via a spark plug hole and in that the valve plates are pressed against their sealing seat in the cylinder head from inside by the resulting pressure in the cylinder space and are held there during the repair work. This results in the advantage that valves are pressed against their seat by the compressed air and that, during repairs to the valve gear, the valve stem is held in such a way by the valve stem guide on the cylinder head that it projects freely outwards. Repair work on the valve gear can thus be carried out without having to remove the cylinder head. The invention also relates to a tool which can be used in carrying out the method and can be screwed into a spark plug hole and via which compressed air can be injected.
