Patent DE-3808076-A1 (DE)
Title: Traversing arrangement
Inventor: WEBER KLAUS
IPC: F16H19/06
Filed: 1988-03-11
Abstract: The traversing arrangement is driven by two belt strands (1) which are moved in opposite directions and has a carriage (5) which is movable parallel to the belt strands on a straight guide (6). The carriage has clamping mechanisms with grippers (12) which are actuated by stationary stops (23) and are held in the clamping position by a spring which passes their dead centre position. By self-locking design of the traversing arrangement, it is possible to keep the spring force low. To this end, the gripper consists of two eccentric discs (66) which are interconnected in a geared manner. On contact against the respective belt strand, a rotary movement with an increasing radius is imposed on the eccentric disc while the other eccentric disc carries out a rotary movement with a decreasing radius. The eccentric discs are braced together with one another in the same direction of rotation by the spring. <IMAGE>

Title: Superfinishing head, in particular for crankshafts
Inventor: STREJC JOSEF DIPL ING
IPC: B24B35/00
Filed: 1988-06-20
Abstract: The invention relates to a superfinishing head for journals, in particular of crankshafts. The aim of the invention is, during the finishing of journals, also to finish their ring grooves, in the case of crankshafts, by means of superfinishing. The object of the invention is to provide a simple way of finishing the crankshaft journals and the ring grooves at the transition to the crank arms in a highly precise and simultaneous manner and to design a finishing head suitable for this purpose. The essence of the invention consists in that the superfinishing head is fixed by its housing to the output shaft of the air vibrator in a guidable manner and is equipped, at the sides, with pivotable arms which are also provided for receiving ring-groove stones. It is advantageous here if the pivotable arms are fixed to a flat spring, the centre of which is secured in the housing of the superfinishing head. Holders for surface stones are fixed to the body of the superfinishing head, sideways on the springs.

Title: Automatic film-loading device for sheet-film cassettes
Inventor: SCHEUFLER GERT DIPL ING
IPC: G03B42/04
Filed: 1988-08-22
Abstract: An automatic film-loading device (1) for sheet-film cassettes (5) has a supply magazine (10) and a sheet-film cassette (5), arranged below said supply magazine, and a sheet-film holder (12) assigned to their removal sides. The sheet-film holder (12) forms a guide channel, open towards the supply magazine (10), for the complete accommodation of a sheet film (6). The guide channel is formed by a stationary upper part (13) and a lower part (14) which can be pivotably disconnected downwards. The lower part (14) pivots a sheet film (6) which is located in the sheet-film holder (12) downwards so that due to gravity the sheet film (6) slides downwards and is transported into the open sheet-film cassette (5) via transport rollers (22). A stop (11, 11a) assigned to the free end of the lower part (14) and extending over its entire pivoting region prevents the sheet film (6) from prematurely sliding out of the sheet-film holder (12), but on the other hand it leaves free the upper inlet region of the closed sheet-film holder (12) and the release region of the lower part (14) which is in the pivoted-down position, so that the sheet film (6) can slide down. <IMAGE>

Title: Ventilating device
Inventor: KODERER MANFRED
IPC: F24F7/013
Filed: 1988-08-27
Abstract: Axial fans for fitting in walls, glass panes and the like have the disadvantage that, particularly when they are used in window and facade construction, the connecting conditions as regards the profiles are not provided. Particularly when a plurality of such fans have to be installed, the mechanical fitting is problematical and the electrical wiring of individual units disadvantageous. A solution to the problem is achieved in that axial fans are mounted into an extruded housing, serving both for mechanical reception and heat insulation, and are wired and produce a ventilation device which is ready for connection and is simple to mount into the window profiles. The ventilating apparatus is used chiefly in window and facade construction. <IMAGE>

Title: Method for rotational speed measurement on electric motors
Inventor: BOHN HEINZ DIPL PHYS
IPC: F04D27/00
Filed: 1988-09-05
Abstract: The invention relates to a method for rotational speed measurement on electric motors, in particular squirrel-cage motors for driving pumps, fans (ventilators) or the like, in which for the purpose of measurement short motor shutdowns of approx. 20 to 100 ms are permissible, and aims to provide a simple and accurate method for determining the motor speed using purely electrical means. The invention proposes for this purpose to interrupt the power supply to the motor at the start of the rotational speed measurement at the instant of a power zero crossing, to measure the voltage generated in this case by the motor as a consequence of the residual magnetisation of the motor, which continues to run because of its inertia, and finally to reestablish the power supply.
