Patent DE-3101595-A1 (DE)
Title: Power supply
Inventor: BARK DIETER
IPC: H02M7/06
Filed: 1981-01-20
Abstract: The present invention relates to a power supply for supplying voltage to a load (which is operated with a pulse sequence of identical polarity) and at the same time to a further DC-voltage operated load using a full-wave rectifier. In this case, full-wave rectifiers may be both two-path rectifiers or bridge circuits. The object frequently exists of supplying a plurality of DC-voltage supplied loads using such a power supply, it then being found in a suitable experiment that not all the loads require a well-filtered DC voltage. The invention makes use of this fact in that it proposes to use the full-wave rectifier in a double manner to the extent that only the more sensitive portion of the loads has the full-wave rectified and filtered voltage made available to it, while the loads with the less critical behaviour are supplied with only a pulse sequence of identical polarity. For this purpose, the invention is for one supply lead of each load to be jointly connected to the DC voltage connection of the full-wave rectifier and for the other supply lead to the DC-voltage operated load to be connected to the second DC voltage connection, while the second supply lead to the load which is operated by a pulse sequence is connected to the AC voltage connection of the full-wave rectifier. This arrangement has the advantage of the rectifier being lower rated and in the capacitance of the capacitors required for filtering being reduced.

Title: Apparatus for continuously carrying out heterogeneous reactions on solids containing activated carbon
Inventor: OESTE FRANZ D ING GRAD
IPC: B01J20/28
Filed: 1981-01-24
Abstract: The appliance consists of a reaction chamber (1) and at least one regeneration chamber (2, 3), through which a multiplicity of reactive endless elements (4) containing fibres of activated carbon spaced at preferably less than 10 mm are passed in countercurrent to the fluid in question. The endless elements (4) are fanned out in the reaction cavity and are thus distributed uniformly across the cross-section. The chambers (1, 2, 3) are sealed at the feed-through points (6) of the endless elements (4). Outside the chambers, they are driven as a rope via a speed-controlled motor (9) which, like the metering appliance (10) for the regenerative fluid, is controlled by a detector (10) for measuring the reaction parameters in the fluid outlet of the reaction chamber (1). <IMAGE>

Title: Heat exchangers for pourable material
Inventor: RUESSEMEYER HANS DIPL ING
IPC: F28D11/02
Filed: 1981-05-14
Abstract: Heat exchangers in the form of rotary drums, rotary tubes or cooling tubes of satellite coolers, such as are used in multiple ways to cool, heat or dry pourable materials, are fitted in their rotating cylinders with so-called pouring inserts (baffles) in the form of scattering blades with the aid of which the material to be treated is intended to be exposed to the treating medium with as large as possible a surface in order to effect an intimate and intensive heat exchange. The formation of the veil in the cylinder, which in turn is dependent on the scattering characteristic of the scattering blades, is decisive for the heat exchange process. The veils of material which are subjected to the treating medium are intended to extend over the entire cylinder cross-section and to have the same thickness and density everywhere. In order to achieve a formation of the veil which is as ideal as possible, as well as to achieve an even more intensive heat exchanger, a new form is proposed for the scattering blades of such heat exchangers. This novel form of scattering blade is characterised by a special construction of at least one of its scattering edges (3, 4), specifically as an undulating curve (7) which extends from one (5) to the other (6) side of the blade and has a wave trough (8) and a wave crest (9). <IMAGE>

Patent DE-3135284-A1 (DE)
Title: Integrated dust-free transport, intermediate storage and positioning of straw bales
Inventor: COST KARLFRIED
IPC: A01D87/12
Filed: 1981-09-05
Abstract: The previous methods for straw handling and straw transport have been unsatisfactory in terms of the time required for loading and unloading, pollution of the environment by loose straw particles and the risk of fire. The large straw bales are loaded onto a slide-like mount at the storage point. This mount is then picked up by the transport vehicle and transported in a closed container. The unloading station is designed for unloading by means of the slide. The figure shows this diagrammatically. The loading operation and unloading operation take up only a very short time, because the entire slide together with straw is moved once each time. Such a method is expedient when relatively large quantities of straw are to be delivered to a consumption point, for example to a central straw-fired plant of relatively high capacity. <IMAGE>

Title: System for the remote location of regenerative intermediate points
Inventor: JEANDOT JEAN-LOUIS
IPC: H04B17/40
Filed: 1981-09-15
Abstract: Regenerative intermediate points are accommodated in a transmission path between two terminal points for transmission (at a given clock rate) of digital information signals in one direction via a forward path and in the other direction via a return path. A system for the remote location of these intermediate points contains a transmitter (in one of the terminal points) for transmitting remote locating commands to the intermediate points via the forward path, carrier signals at the said clock rate being modulated in/detected in this transmitter with the aid of an amplitude modulator, and output signals of a command sequence generator and, furthermore, in each intermediate point, a loop circuit between the forward path and return path in a corresponding manner, having an associated control circuit which interacts with a detector for the presence of carrier signals in the forward path, for receiving remote locating commands. Without using addresses allocated to the intermediate points, a reliably acting control circuit of simple structure is obtained in such a remote locating system in that the command sequence generator is set up to supply command sequences which are formed by in each case one pulse series having at least one pulse, which pulses are transmitted by interrupting the carrier signals with the aid of the amplitude modulator. <IMAGE>

Title: Method and apparatus for the contour machining of a workpiece
Inventor: INOUE KIYOSHI
IPC: B23H7/06
Filed: 1982-03-23
Abstract: Method and apparatus for the contour machining of a workpiece by axial conveyance of an electrode wire through the workpiece, while simultaneously feeding the workpiece relative to the axis of movement of the electrode wire in a plane essentially perpendicular to the axis of movement, for the progressive electro-erosive cutting of a recess along a programmed path closed upon itself and having a given contour, as a result of which the workpiece is if necessary separated into a centre part and a peripheral part relative to the contour-cut recess. The workpiece and the wire-holding and guide members are positioned in such a way that the workpiece can move relative to the moving electrode wire in a perpendicular plane with a two-dimensional coordinate system. The programmed path closed upon itself is located on the positioned workpiece in the two-dimensional coordinate system and is subdivided into a top path and a bottom path. The positioned workpiece and the wire-holding and guide members are fed relative to one another for the continuous feed of the moving electrode wire along the programmed cutting path in the coordinate system, and in fact at first along a part of the top path, then along the entire bottom path and finally along the remaining part of the top path. If the resulting centre part is cut off from the peripheral part, it falls within the peripheral part and rests on it without striking the electrode wire and without squeezing the electrode wire against the walls of the peripheral part.

Title: Polyhedral playing die
Inventor: SCHWEISFURTH GUENTER
IPC: A63F9/04
Filed: 1982-08-20
Abstract: A polyhedral playing die for party games, games of chance or other types of games for entertainment is to be provided with the largest possible number of side surfaces. On a spherical body, planar and regular trapezium surfaces are thus formed, between two pole-side sphere caps, over a plurality of length zones and width zones which are symmetrical with respect to a great circle. In this arrangement, in each case the two trapezium surfaces located in two mutually symmetrical width zones are configured with the same surfaces. In contrast, the trapezium surfaces provided in mutually unsymmetrical width zones have different configuration. The trapezium surfaces located in the outer width zones are provided, towards the sphere caps, with arcuate delimitation edges. On the spherical body, the trapezium surfaces are preferably designed in four width zones which are symmetrical with respect to the great circle, to be precise such that such trapezium surfaces are distributed over ten length zones.
