Title: Domestic clothes drying machine - directs cooling air from front port into condenser and around drum to rear exit
Inventor: BOCK HELMUT DIPL ING
IPC: D06F58/24
Filed: 1980-02-05
Abstract: A domestic clothes drying machine with a revolving drum uses hot air, circulated by a fan, to release its entrained moisture in a condenser in the base of the machine. The coil air is drawn in by another fan from a port in the front of the machine housing at the bottom and is directed, after it has passed through the condenser, inside the machine and around the drum. It finally leaves at the top rear of the machine. The cooling air is thus not heated before it enters the condenser and enters at the hot end of the container. This results in a 30% improvement in heat exchange.

Title: Commutator for electrical machines
Inventor: SCHWERDTLE MARTIN
IPC: H01R39/32
Filed: 1981-05-26
Abstract: A commutator (3) is proposed for electrical machines, especially for starter motors of internal-combustion engines, which commutator (3) conforms with the particularly stringent requirements, for rugged operation in motor vehicles, for the strength of the mechanical and electrical connection between the commutator segment (2) and the connecting tab (12). The segments (2) each have a V-shaped slot (6) in their end (5) on the armature side, in which slot (6) the V-shaped base (15) of the connecting tab (12) (which has parallel limbs) is inserted. The V-shaped construction of the slot (6) and of the base (15) of the connecting tab (12) results in a large-area contact between the connecting tab (12) and the segment (2), with high mechanical strength and a good electrically conductive connection between these two parts (2 and 12). <IMAGE>

Title: Device for the automatic opening and closing of pivotably mounted forcing-frame windows and the like
Inventor: WEBER LUDWIG
IPC: E05F15/71
Filed: 1981-07-07
Abstract: The invention relates to a device for the automatic opening and closing of pivotably mounted forcing-frame windows and the like, having a pressure-applying unit comprising a fluid container and a pressure-applying rod which can extend owing to the temperature-related change in volume of the fluid, the pressure-applying unit, on the one hand, making contact in an articulated manner, at a fixed articulation point, with a lifting member arranged pivotably beneath the window and, on the other hand, being mounted pivotably on a carrying arm which carries the pin for the lifting member and starts from a securing means which can be bonded on the window such that it is stationary. In the case of a known device, the lifting member is a rigid arm, whose end, remote from the articulation point on the carrying arm, bears on the window, to be opened, from beneath, to be precise on the end thereof which is to be lifted. On opening, window and lifting members have to slide along one another. In order, in the case of the consequently changing point of contact of the lifting member on the window, to secure a specific, temperature-dependent opening width, the size ratios have to be coordinated with one another. The object of the invention is to avoid the abovementioned disadvantages and to permit attachment without taking the size ratios into account and without specialist knowledge of the person carrying out the attachment. The object is achieved in that the carrying arm has an articulation between the securing means and the articulation point of the pressure-applying unit, that the lifting member makes contact with the pivotable window by means of an articulation connection, and that all the articulation axes of the device run parallel to one another. Consequently, this makes it possible for window and lifting member no longer to slide one upon the other, for the lifting point not to change and for size ratios no longer to have any role. The window is, then, largely secured, by means of the weight of the device, against being caused to move by the wind.
Patent DE-3132668-A1 (DE)
Title: Process for producing alkali-free manganese raw material from cryptomelane
Inventor: GOCK EBERHARD
IPC: C22B47/00
Filed: 1981-08-14
Abstract: The direct use of cryptomelane ores (K</=2Mn8O16) in metallurgical furnaces for producing manganese metal or manganese alloys is uncommon because of reactions of the potassium with the furnace brake linings and the charge, which cause a reduction in the service life of the reactor and lead to interference with the reaction process. Since so far no process is known which permits a complete extraction of potassium from cryptomelane ores on an industrial scale, this ore type represents a potential raw material reserve. It has now been found that a complete selective extraction of potassium from cryptomelane ores with dilute sulphuric acid in a stoichiometric ratio to the potassium content of the ore at ambient temperature (15 to 35 DEG C) is possible if, by prior heat treatment in an air stream between 900 and 1200 DEG C, the crystal lattice structure of cryptomelane is disturbed to such an extent that the ratio, determinable by X-ray defraction analysis, of the X-ray defraction intensities at the lattice planes 410/211 of the disturbed material (I) relative to the undisturbed starting material (I0) is less than 0.1. In the presence of at most 5% by weight of carbon, the temperature for the heat treatment of cryptomelane ores in the air stream as a prerequisite for subsequent complete potassium extraction can be lowered to 600-800 DEG C. In addition to the recovery of potassium-free manganese raw material, the extraction process allows, owing to its selectivity, the additional recovery of potassium sulphate, potassium hydrogen sulphate and/or potassium sulphate fertiliser.
