Title: Process for air purification
Inventor: HOELTER HEINZ DIPL ING
IPC: F24F3/16
Filed: 1985-01-16
Abstract: It is known to carry out purification of air either by a chemisorption method or alternatively by a so-called air scrubbing method. In order to produce air as fresh for breathing as for example is available in high mountain regions, according to the invention it is proposed that a multi-stage process is used in which the first stage used is a chemisorption filter method (1), to which, as second stage, is connected downstream a moistening by an electrical cold scrubbing device (2), downstream of which the air, by means of a room temperature apparatus (3) is brought to the desired temperature and moisture. <IMAGE>

Title: Method for the production by forming of annular pressed parts, in particular inner races of rolling bearings
Inventor: EBERLEIN LUDWIG DIPL ING
IPC: B21K1/04
Filed: 1985-10-08
Abstract: The invention relates to a method for the production by forming of annular pressed parts, in particular inner races for rolling bearings or similar annular profiled parts made from high-strength materials. The aim of the invention is to provide a method which ensures effective utilisation of the material used with a high degree of deformation, short production time and a large number of pieces per dye. The object of the invention is to design the process stages in such a way that abrasive annular parts are produced in an effective manner in two forming stages from solid material. According to the invention, the object is achieved by the fact that the cup-shaped intermediate shape is pierced, expanded and calibrated in one process stage, the spigot diameter/internal diameter ratio of the cup-shaped intermediate shape produced in a preliminary stage by known combined extrusion being 1.3:1 or even less. The area of application of the invention is primarily in machine construction for the industrial production of undercut annular parts with high accuracy by cold forming, especially for relatively small dimensions. The method is especially suited to the production of rolling bearings. <IMAGE>

Patent DE-3613503-A1 (DE)
Title: Stationary dust and dirt suction-extraction system for fibre-processing machines, especially looms
Inventor: ZUBLER KURT DIPL ING
IPC: D01H11/00
Filed: 1986-04-22
Abstract: In fibre-processing machines, a large quantity of dust and fibre fly occurs as a result of fibre abrasion and, in weaving machines, is additionally laden with tacky size. The disadvantage of previous stationary suction-extraction systems is that suction extraction takes place constantly at all the orifices and therefore a large amount of energy is required. Mobile suction-extraction systems are not so effective, since they usually do not touch all the points where dust is generated. In this invention, two systems are installed, one for suction and one for blowing. However, not all the orifices are constantly subjected to suction or pressure, but only ever a small number, since the individual orifices can, as desired, be connected to the suction source or, in the case of the blowing system, to the pressure source. Suction extraction takes place for a predetermined time through each suction orifice. Blowing is carried out via the associated blowing orifice at the same time, and the suction is assisted. After the predetermined time has elapsed, suction and blowing are terminated here, and the operation is recommenced at other orifices, until all the orifices have been treated, and the circuit begins again.

Filed: 1986-06-14
Abstract: The invention relates to a process for producing high-strength gypsum construction elements, in particular gypsum construction panels, which can be used for new construction and reconstruction in the field of residential, communal and industrial building. Using a new production process, the aim is to produce an inexpensive, easily worked gypsum-bound construction element in which fine wood particles, which are produced in large amounts as waste product, can be used to improve the properties. The aim is to produce large surface-area, thin-walled high-strength gypsum construction elements with a dry bulk density of between 1.3 and 1.8 kg/dm<3>. With the use of known process steps in the production of gypsum construction elements in which according to the invention wood particles with a size ratio of length: width: thickness = 1:1:0.1-0.2 in the millimetre range and the gypsum in a weight ratio of 0.1-0.3 based on their dry weights, the wood particles being impregnated with water such that a water/gypsum value of 0.2-0.3 is achieved, are mixed with one another in a free-flowing form and subsequently pressed.

Title: Heading machine for a winning gallery
Inventor: PAURAT FRIEDRICH WILHELM
IPC: E21D9/10
Filed: 1986-08-06
Abstract: Heading machine for a winning gallery in an underground mining operation, comprising a machine frame, crawler unit, conveying device and winning unit with cutting and loading drum as well as a shearer drum, the shearer drum extending over the entire length of a boom up to the front area of the machine frame. The boom is pivotable merely about a horizontal axis pointing in the driving direction. The cutting and loading drum can be moved up and down on pivoted arms projecting from the machine frame and works under the shearer drum in a projection to the horizontal. During the pivoting movement of the boom, the shearer drum leaves a frustoconical cut-out in the face. During the movement of the pivoted arms, the cutting and loading drum wins the frustoconical cut-out in the area in front of the machine frame. A dust shield is arranged in the area behind the shearer drum and to the side of the machine frame. The dust shield is attached to the heading machine and extends up to the limit of the gallery. It has an air door at least on one side next to the machine frame. The dust shield can be provided with at least one fresh-air supply duct which in the area of the limit of the gallery leads into the space in front of the dust shield. The fresh air as well as dust-laden air can be fed or drawn off through ducts in the machine frame. <IMAGE>

Inventor: BRUEGMANN DIRK
IPC: B29C48/92
Filed: 1986-08-19
Abstract: The gauged profile of an emerging extrusion is monitored and any change is detected. In the process any deviation from the desired dimensions of the profile, or any deviation from the desired pressure at one point, is recorded and a corresponding change is made in the speed of a traction device or in the speed or heating of the extruder. ADVANTAGE - The process makes no actual contact when measuring the extruded dimensions but any change in the proportions of the extrusion is detected immediately and corrected.
