Patent DE-3605507-A1 (DE)
Title: Apparatus for gas-liquid mass transfer in the counter-current contact process
Inventor: MERSMANN ALFONS PROF DR ING
IPC: B01J8/10
Filed: 1986-02-20
Abstract: In an apparatus for the gas-liquid mass transfer in the counter-current contact process, in which a gaseous phase flows through a liquid phase in the centrifugal field of a sieve drum radially from the exterior to the interior through a sieve surface, an equalisation of the residence time of all gaseous, liquid and/or solid reaction partners is to be produced. For this purpose it is proposed to arrange concentrically at radial distances a plurality of preferably cylindrical sieve surfaces which are closed in alternating sequence at one end of the sieve drum and are provided at the opposite end of the sieve drum with an annular overflow weir which is connected to an overflow duct which leads to the nearest radially outer sieve surface, in which case the gas can be fed from the concentrically arranged sieve surfaces at least to the radially outermost sieve surface through a closed gas duct and flows from the exterior to the interior through the sieve surfaces and the liquid layers lying thereon.

Title: Machine tool for machining workpieces
Inventor: SCHMID SIEGFRIED ING GRAD
IPC: B23Q11/08
Filed: 1986-04-22
Abstract: A machine tool (11) for machining workpieces has a table, arranged on a machine frame, for clamping the workpieces, a column (21) which is traversable in the X- and Y-coordinate axis and on which a tool spindle (27) traversable in the Z-coordinate axis is arranged, and furthermore a telescopically arranged cover (31), having movable cover parts (34), for the guideway of the X-coordinate axis, and a protective-wall arrangement (40) for the working space, which has front, side and rear protective-wall sections (41-44). A machine tool (11) of this type is to be provided with a less complicated, but just as reliable and tight protective-wall arrangement (40) for the working space. This is achieved by the rear protective-wall section (44) of the working-space protective-wall arrangement (40) being arranged perpendicularly and on the guideway cover (31) and having wall parts (56) which are arranged telescopically relative to one another and can be moved telescopically together with the telescopically arranged cover parts (34) of the guideway cover (31). Here, the rear protective-wall section (44) is arranged on both sides of the traversable column (21). <IMAGE>

Title: Shearer loader with cutting drums rotating about vertical or horizontal axes
Inventor: KNORR VOLKER
IPC: E21C27/02
Filed: 1986-10-10
Abstract: The invention deals with a shearer loader (1), the cutting drums (6) of which rotate about a vertical or horizontal axis (11). Each of the cutting drums (6) is mounted on a supporting arm (10) rigidly or pivotably connected to the machine body and is connected to the drive motor in the machine body via a gear train (13) arranged in the supporting arm (10). A cutting wheel (16) lies concentrically with respect to the cutting-drum axis (11) in a supporting-arm plane (A) running at right angles to this axis (11). It transmits the rotary movement of the drive motor to the cutting drum (6). The peripheral surface of this cutting wheel (16) is fitted with a tooth system, meshing with the supporting-arm gear train (13), and with cutting tools (18). The latter lie in the peripheral plane of the teeth and project beyond their tip circle diameter. In each case one cutting-tool pair is arranged between two teeth each, and the gear (13) meshing with the cutting wheel (16) has a pocket (17) between two teeth each. The pocket (17) receives the heads of the cutting tools (18) during the rotation of the wheel (16). The cutting wheel (16) and gear (13) are subdivided by the horizontal supporting-arm plane (A) into two discs (13a, 13b, 16a, 16b) of the same height. One row each of cutting tools (18) is located on both the top disc (16a) and the bottom disc (16b) of the cutting wheel (16). In addition, both discs (13a, 13b, 16a, 16b) of the cutting wheel (16) and of the ... Original abstract incomplete. <IMAGE>

Title: Method for heat recovery in a dryer for cereals or similar products
Inventor: FISCHER RUDOLF
IPC: F26B23/00
Filed: 1987-04-23
Abstract: The invention relates to a method for heat recovery in a dryer for cereals or similar products, in which the cereals to be dried run through, according to the circulating or the continuous flow method, a silo-like container of perforated design while at the same time a preheated drying-air flow is blown through this container. According to the invention, a closed housing (1) likewise designed in a silo-like manner is put over the perforated silo-like container (2), the drying air flow (17) enriched with moisture is sucked off via one or more openings (8) of the housing (1) and this sucked off air flow is conducted via a heat exchanger (11, 16), via which the drying air flow supplied to the silo-like container (2) is also conducted. <IMAGE>

Title: Miniature electric motor, in particular for miniature models of railway tractive units, operated with direct current
Inventor: REGAZZOLI GIANFRANCO
IPC: A63H29/22
Filed: 1987-05-04
Abstract: The invention relates to a miniature electric motor which is operated with direct current and contains a rotor (10) and an inductor (stator)(11) which are combined with a housing body (12), the rotor (10) being equipped with inertial masses (20) attached to the core (15) of the rotor and with metallic blocks (20'), and the inductor (stator) (11) being formed from two induction poles (21) which are connected to two induction coils (22, 23) with windings which are opposed to one another and are optionally fed via two corresponding diodes (24, 25) so that the magnetic polarity of the two induction poles can be inverted and the rotation of the motor in opposite directions can be made possible, the induction poles becoming demagnetized in the stopping phase of the motor so that a braking effect is not exerted on the rotor. The miniature motor is particularly suitable for driving miniature models of railway tractive units and the like and the high degree of inertia of its motor permits the respective vehicle to be started up and stopped gradually and realistically. <IMAGE>

Title: Filter for the purification of a gaseous medium
Inventor: BENZEL MARTIN DIPL ING
IPC: B01D53/08
Filed: 1987-06-16
Abstract: For the purification of a gaseous medium, this is passed horizontally through a moving bed of pourable or flowable filter material. The moving bed is situated within a chamber 4, which is subdivided by a partition 7 into an upper and lower chamber 8 and 9 respectively. The lower chamber 9 is additionally divided by a vertically arranged partition 10 into a front and back lower chamber section 12 and 13, respectively. Each lower chamber section 12, 13 is furnished with its own draining connection branch and shut-off valve 14 and 15. This design makes it possible to empty the pollutant-laden filter material from the front lower chamber section 12 and to replace it by partially-laden filter material from the upper chamber 8, before a similar exchange takes place in the rear lower chamber section 13, since the filter material situated therein remains completely free from certain pollutants and is only adequately loaded with the remaining pollutants after relatively long periods of time. <IMAGE>

Title: Fitting for a tiltable, sidetrackable and laterally slidable wing of windows, doors or the like
Inventor: LAHMANN ERNST
IPC: E05D15/10
Filed: 1987-07-03
Abstract: What is provided is a fitting for a tiltable, sidetrackable and laterally slidable wing of windows, doors or the like, which allows an easy dismounting of the wing and, at the same time, a safeguard against unauthorised dismounting at its wing-side articulation points located in front of the wing plane, and in which the two swivel arms are coupled by means of a link mounted in an articulated manner between the points of articulation of the swivel arms located at the ends. At the same time, the link is expediently arranged in such a way that it always remains in the contour region of a wing-side screw-on plate. The articulation points on the fixed-frame side are provided on sliding pieces which are dimensioned and coordinated with the inner cross-section of a running rail located on the fixed-frame side and with its orifice width, in such a way that the movable unit of the fitting can be introduced into the rail and removed from the latter easily merely by setting it obliquely and can be secured in the running rail by pivoting into the operating plane.
