Patent DE-3046156-A1 (DE)
Inventor: ZIMMER ERNST
IPC: F16D55/228
Filed: 1980-12-06
Abstract: A brake effective between a rotating part and a non-rotating part has a substantially nondeformable brake disk secured to one of the parts, centered on an axis, and having a pair of axially oppositely directed brake-disk faces. A housing is secured to the other of the parts, at least partially surrounds the brake disk, and has a pair of end walls having wall faces axially confronting the respective disk faces. Respective brake elements are limitedly axially displaceable between the wall faces and the respective disk faces and engageable with the respective disk faces. Formations on the elements and housing prevent the elements from rotating relative to the housing. Spring packs between the brake elements and the respective wall face urge the elements with a substantially constant force axially together into braking engagement with the disk. Seals between the brake elements and housing define a pressurizable chamber between the brake elements. The chamber can be pressurized to move the elements axially apart and out of braking engagement with the disk.

Title: Auxiliary bladed stirrer for liq. manure - is rotated by air blast from rotating nozzle in storage tank
Inventor: BOEDECKER KNUTH
IPC: B01F7/02
Filed: 1980-12-09
Abstract: Liq. such as liq. manure which contains suspended solids is stored in large containers and to prevent settling is periodically stirred by an air nozzle rotating about its axis. The stirring effect is increased by an auxiliary rotary stirrer located radially outwards from the nozzle. The auxiliary stirrer is provided with blades and is inclined to the air jet from the nozzle which therefore rotates the blades. The rotary stirrer is of circular or plate shape, and at its periphery can have fingers projecting radially outwards to provide still further stirring. The auxiliary stirrer rotates about an axis inclined from the main stirrer axis and may be driven by a flexible shaft. The effective stirring range is increased, so the main stirrer is less likely to need moving or the provision of further stirrers. No motor is needed for the auxiliary stirrer, which is rotated by the air nozzle.

Title: Control device for load-independent feed control for pressure-medium-operated consumers
Inventor: STAMMER ARNO DIPL ING
IPC: F15B13/04
Filed: 1981-01-31
Abstract: The invention relates to a control device for load-independent feed control for at least two pressure-medium operated consumers connected in parallel, in which a directional control valve is allocated to each consumer, and a pressure-difference valve is provided between feed line and discharge line. The invention is to eliminate impairment of the control sensitivity and the operating reliability of the directional control valves and at the same time ensure trouble-free operation of several consumers with different loading. The object of the invention is to create such a control device in which no unfavourable effect of transverse forces on the spools of the directional control valves occurs and in which it is ensured that, when a second consumer is connected to an already connected consumer, the undiminished pressure of the consumer subjected to the higher load is always applied in the spring space of the pressure-difference valve and sensitive control of the consumer in each case subjected to the low load is also possible. This is achieved by the connection according to the invention between the spring space and the discharge line or in each case one of the two allocated consumer lines via the centre annular control passage of three annular control passages arranged next to one another in each directional control valve. <IMAGE>

Title: >>Arrangement for obtaining a clock signal<<
Inventor: FRIEDRICHS BERND
IPC: H04L7/02
Filed: 1981-06-20
Abstract: The invention relates to an arrangement for obtaining a clock signal which controls an equaliser in baseband data transmission, redundancy-added multistage codes being used as line codes. In the equalisation of multi-valued communications signals transmitted at high bit rates, it has become evident in the use of specific equaliser structures that the control signal for a clock generation device can be obtained in simple fashion from the signals occurring in the equaliser and from the received distorted signal. It is particularly advantageous that synchronisation is possible with no preamble phase or other additional synchronisation signals.

Title: Method for controlling the output current of a converter, and a circuit arrangement for carrying out the method
Inventor: HEINLE GEORG DIPL ING
IPC: H02P27/06
Filed: 1981-08-03
Abstract: In the case of the method according to the invention, the phase angle of the output current is adjusted by switching over between two discrete vectors (I0-I5) which are in each case predetermined by a switching combination of the switches of the associated invertor, the vector having a smaller associated phase angle, which is separated from the required value by the angle  phi , being selected for the portion <IMAGE> of the cycle duration T, and the second vector for the remainder of the cycle duration. The required value for the magnitude of the output current (/I/req) is fed to a current regulator for the intermediate-circuit current via a correction element, which multiplies the required value by the correction factor <IMAGE> It is thus possible to adjust the output current of the converter at will in terms of magnitude and phase angle or to vary the phase angle at a constant angular velocity, so that a sinusoidal output voltage is obtained.

Title: Process and apparatus for measuring the recombination time of thermal neutrons with materials in and in the region of boreholes
Inventor: SCHULTZ WARD EDWARD
IPC: G01V5/10
Filed: 1981-08-21
Abstract: The present invention relates to a process and an apparatus for simultaneously measuring the formation component and the borehole component of the lifetime or decay time of thermal neutrons. Borehole and formation are irradiated with 14 MeV neutrons. During the period between neutron pulses, the capture gamma radiation is measured in at least four non-overlapping, successively following time intervals. The background radiation is likewise measured periodically. The capture radiation measurements corrected by the background are combined in order to derive simultaneously the formation component and borehole component of the neutron lifetime, which are then recorded as a function of the depth of the borehole. <IMAGE>

Title: Process for producing cross-country skis and device for carrying out the process
Inventor: PLENK KLAUS
IPC: A63C5/12
Filed: 1981-09-18
Abstract: The process for producing cross-country skis concerns a foam injection process in which, after the final surface treatment, for example after the screen printing and coating process and/or after the running surface forming and after the final shaping, the compression member and/or tensile member are laid in a mould consisting of an upper mould and lower mould and are pressed, by sub-atmospheric pressure on the inner surfaces of the upper mould and lower mould, onto a surrounding seal. After the foam-filling of the ski, no further processing operations are required on the foam-filled ski, resulting in a very low proportion of rejects, a low proportion of labour costs, a high raw material saving and a low energy consumption with a simultaneous improvement of the ski quality. In the process according to the invention, the cover laminate or the compression member and/or the tensile member or the running surface can be very inexpensively processed or printed and coated as roll goods, by the running meter, before the foaming operation. A device for carrying out the process for producing cross-country skis is described.
