Title: Door closing mechanism with sprung piston
Inventor: SCHECK GEORG
IPC: E05F3/10
Filed: 1986-11-10
Abstract: The door closer housing contains a piston working with a closer spring and hydraulic damper and geared to a closer shaft by a pinion whose lever arms vary in length round the pinion circumference. The pinion side (25) gearing and/or the complementary toothing (27) for the pinion (25) should vary in profile displacement via their roll curve (26,28) and/or this should vary their modulus and/or vary their flank angle using one or more asymmetrical teeth having a more acute flank angle on the pressure side than on the non-pressure side. Pref. the profile displacement of the pinion (25) is negative in one sector of the roll curve (26), thus ensuring a small door opening angle. It can instead be positive in one sector (26), thus ensuring a large door opening angle.

Title: Dry multi-plate friction clutch
Inventor: HUNECKE JOSEF
IPC: F16D13/52
Filed: 1987-01-20
Abstract: Outer plates rotating with the input shaft of a dry multi-plate friction clutch have a tendency to execute vibrations in the disengaged condition of the clutch and these make themselves heard as a troublesome jangling noise. This source of noise is to be eliminated by the new multi-plate friction clutch. In order to deprive the outer plates 5 of any opportunity to move and thereby generate noise, they are divided into a plurality of plate segments 5c. By virtue of this division, the individual plate segments 5c are pressed firmly into their mounting by the centrifugal force which arises when they rotate, so that they no longer have any opportunity to perform uncontrolled movements and generate noise. The multi-plate friction clutch is suitable, in particular, for drives in which the operating time with the clutch engaged is relatively short in comparison with the operating time with the clutch disengaged. <IMAGE>

Filed: 1987-05-06
Abstract: A method and apparatus for manufacturing an otoplastic. An otoplastic is manufactured directly in the ear of a hearing-impaired person in that a deformable envelope is pulled over a die or over a shell or over an overlayed over-shell. This apparatus is then supplied with flowing otoplastic material between the die and the envelope, being supplied therewith in the ear. The envelope expands and assumes the shape of the auditory canal. After hardening or curing of the otoplastic material in the ear of the hearing-impaired person, the envelope and the die are removed and a module of either an in-the-ear or of a behind-the-ear hearing aid is integrated therewith.
Patent DE-3715726-A1 (DE)
Title: Hand-lever-operated incremental control mechanism for forwards and backwards swivelling steps in a variable sequence
Inventor: SCHNEIDER FRITZ ING GRAD
IPC: B60N2/90
Filed: 1987-05-12
Abstract: The intention is to make adequate provision against the development from an incomplete swivelling step of intrinsic dynamics in which the segment gear, connected rigidly to the output shaft of the incremental control mechanism, beginning with the slipping through of a tooth cuts across to another path limitation. In addition, deficiencies are to be avoided when the incremental control mechanism is to return into its neutral position after a swivelling step has been discontinued. The drivers on the hand lever of the incremental control mechanism are therefore equipped with a control pin which is assigned a fixed restraining dog with a separate return section for incomplete swivelling steps. At the same time, the entire disengagement in each case of one of two pawls is restricted to a minimum part of the swivelling-step backlash. The incremental control mechanism is particularly suitable for seat adjustment in motor vehicles.

Title: Process for producing iron-neodymium-dysprosium-boron alloys
Inventor: FERNENGEL WILHELM DR
IPC: C22C1/02
Filed: 1987-10-01
Abstract: By means of the addition of dysprosium oxide to Fe-Nd-B base alloys, the coercive field strength of magnets produced on this basis can be very considerably improved. The addition has hitherto been carried out purely powder metallurgically. This has the disadvantage that losses in residual magnetism have to be accepted. The invention provides a solution by the addition of dysprosium oxide powder being carried out by melt metallurgy. Preferably, a granular material of pressed dysprosium oxide powder is mixed into the melt. Nd-Dy-(Fe) pre-alloys can also be produced in the melt by the same process.

Title: Grinding machine and process carried out thereby
Inventor: ZUERN DIETER DIPL-ING
IPC: B24B49/18
Filed: 1987-10-28
Abstract: The grinding machine with a rotating grinding wheel (9) and a worktable displaceable to and fro relative to the latter is equipped with a dressing device (2) fixed on the worktable, with the aid of which dressing device the grinding wheel (9) can be dressed and, if appropriate, also shaped. The grinding and dressing are effected via a control (12, 13) in particular a programmed control. The precise position of the tip (6) of the or each dressing element (4, 5) is determined with the aid of a measuring device (7) using a feeler which works with or without contact. In the event of a deviation of the actual value from the desired value, this deviation is set off against the value in the programme. If this grinding machine is now equipped with an additional measuring device (14), it is possible to determine the precise dimensions of the workpiece (11), in particular after grinding. If also a deviation of the actual value from the desired value is found, this difference can also be set off against the values in the programme and taken into account via a new input of the desired value or desired values during the subsequent grinding, on the one hand, and dressing of the grinding wheel, on the other hand. <IMAGE>

Title: Circuit arrangement for telecommunication switching systems, particularly telephone switching systems, with facilities for detecting individual switching events arriving in a sequence
Inventor: DAISENBERGER GEORG DIPL ING
IPC: H04Q3/00
Filed: 1987-10-30
Abstract: A dividing device for an irregular sequence of individual switching events in several subsets, which can be detected in total sets, consists of a cascade of counters which are fewer by 1 than intended subsets. Each of these counters which can be incremented by these events, selects and signals the individual switching events in each case allocated to one of the subsets and only forwards the in each case remaining ones of these to the next counter in each case following in the cascade. The totality of these events is only supplied to the first counter. The last counter signals the events allocated to two subsets. Each counter is incremented cyclically and, with each event supplied to it, in each case by a number of steps which corresponds to a quota relating to the respective subset. With each overflow, each counter signals a corresponding event as allocated to the relevant subset. Each counter can be set - in the quantitative sense - to a counter-individual counting cycle which results from the sum of a proportion, graded in steps, of corresponding quotas. <IMAGE>
