Title: Two-pulse invertor having a device for tolerance-band control
Inventor: GOOD PAUL DIPL ING
IPC: H02M7/5387
Filed: 1982-08-27
Abstract: A two-pulse invertor (1) having a device for tolerance-band control with two partial invertors (2, 3) between which a load (4) is connected, and having comparison of the desired value currents (is) and the actual value currents (ii) in order to achieve a predetermined current response is designed such that each of the two partial invertors (2, 3) is connected to a dedicated comparator (6, 7), and such that the switching levels of the individual comparators (6, 7) are mutually offset by the associated hysteresis setting for both partial invertors (2, 3). This allows the switching frequency of the individual parts to be held lower or the ripple on the output current to be reduced. <IMAGE>

Title: Counterflow heat exchanger with spiral surfaces
Inventor: PESCHKE RUDOLF
IPC: F28D9/04
Filed: 1982-09-21
Abstract: In this drum-like heat exchanger having spiral surfaces, two media flow through mutually separated ducts in opposing directions 2. The direction of flow extends parallel to the drum axis. Glued in on both end faces of the drum 11 are spacer segments 5 and 6 which simultaneously form the closing points of the ducts. They are arranged such that all the closing points of one and the same duct come to lie one above another, so that it is possible by means of a mounted distributor rim 3 and 4 shaped like a toothed wheel to discharge the two media separately from one another into an internal header 7 and 8 and into an external header 9 and 10. This wound drum renders the heat exchanger easy and economic to produce. <IMAGE>

The chain wheels are arranged on the dividers in such a way that the chains converge approximately in the same way as the drawing-in channel and run towards one another in a V-shaped manner and, in the region of the counter-cutter, mesh in one another with a slight play corresponding, for example, to the stalk thickness.
Patent DE-3300948-A1 (DE)
Title: Improved support post for vines and the like
Inventor: WAUGH CHARLES JUNIOR
IPC: A01G17/14
Filed: 1983-01-13
Abstract: Metal support post with W-shaped cross-section, the main legs of the W not being sharply canted into the flanges on the outer edges of the legs but merging via transition sections which are relatively weakly bent so that the edges of the flanges lie lowered approximately 60 DEG  out of a plane which extends via the crowns formed by the connection sections, these edges not being notched but knurled. Furthermore, longitudinally extending ribs are formed into the main legs. A post is thus obtained, with superior torsional and bending strength, which is suitable for use of harvesting machines without damaging these machines. It makes it possible securely to fix wires of any thickness at any distance and at any height without them being weakened in time by wear against the support points on the post. <IMAGE>

Title: Dry razor
Inventor: RIEDEL ERICH O DIPL ING
IPC: B26B19/42
Filed: 1983-01-22
Abstract: As is shown in Figure 1, the invention relates to a dry razor for aligning and cutting the hairs which are to be cut off. In this case, a voltage field is applied to the cutting surface 25, the guide strips (10, 15, 16) being pole supports. As a rule, furthermore, a guide strip (10) which acts as a hair lifter is arranged centrally between two cutting-foil surfaces (20). On the side close to the cutter, the individual guide strip has a guide edge which can be constructed at an acute angle, in a concave-conical manner, or like a comb. As a result of these measures, a limited electrical field is produced on the skin, which field has the effect of aligning the hairs and leads to a favourable cutting angle, which means the same as a considerably improved shave. <IMAGE>
Patent DE-3305364-A1 (DE)
Title: Terminal for lightning protection installations
Inventor: PROEPSTER JOHANN
IPC: H01R4/66
Filed: 1983-02-17
Abstract: There is a terminal for conductors consisting of different metals, in which a compression piece (1) and a further compression piece (2) are drawn together by means of a screw connection (6) and in which a contact plate (3) is arranged between the two compression pieces. In this case, it is desired to enable contact to be made by conductors of two different metals with terminal parts consisting of suitable metals in a simplified manner, while retaining the compression pieces which consist in each case of only one metal. This is achieved in that the two compression pieces (1, 2) consist of different metals adapted to the metals of the conductors, to be precise, layers (4, 5), which consist in each case of these two metals and are internally connected to one another and form the contact plate (3). In this terminal, only the contact plate is produced from different metals and the compression pieces are produced in each case from only one metal, so that they can optionally be paired with compression pieces of the same or a different metal. <IMAGE>

Title: Circuit arrangement for reducing the stimulus resistance of telephone sets
Inventor: SCHMIDT KLAUS DIETER DIPL ING
IPC: H04M1/738
Filed: 1983-04-12
Abstract: A circuit arrangement for reducing the stimulus resistance of telephone sets is indicated which has a stimulus arm in parallel with circuit components of the telephone set carrying loop current. To ensure that the stimulus response is adequately low during the stimulus interval, but is adequately high during a speech connection even in spite of variances in the characteristic data of the components, at least three self-conducting field-effect transistors are provided in series in the stimulus arm, where the middle field-effect transistor is of the opposite conductance type to the two outer field-effect transistors. The gate of the middle field-effect transistor taps a control voltage which is dependent on the loop current irrespective of the polarity, and the gate of the two outer field-effect transistors taps at least the drain source voltage of the middle field-effect transistor from the stimulus arm as a control voltage.

Title: Device for the removal of renal calculi
Inventor: KORTH KNUT DR
IPC: A61B17/22
Filed: 1983-04-16
Abstract: A device (1) (Fig. 1) forms a loop catheter for the removal of renal calculi. It has a guide tube (4) in which a loop wire (5) is mounted so as to be longitudinally movable to and fro. On the inner end (7) of the guide tube (4) this wire (5) emerges from the guide tube (4) and is fixed with its free end to the guide tube (4) with a small distance from the outside of the point of emergence (8). This results in the formation of a loop (9) which can be varied by longitudinal displacement of the wire (5) from the outer end (11). The guide tube (4) thus essentially has a guiding function, whereas the wire (5) forms an active, easily manipulated loop (9) from the point of emergence (8) to the fixing point (10). This active loop permits, in particular, removal of renal calculi from renal calices in which the space available is correspondingly restricted without any danger of injuries to the surrounding tissue and the like. <IMAGE>

Patent DE-3321463-A1 (DE)
Title: Apparatus for separating items which can be supplied as bulk goods
Inventor: BELZNER WERNER
IPC: B65G47/14
Filed: 1983-06-14
Abstract: The apparatus has a conveying track (Fb) which is mounted such that it is capable of vibration and can be set into vibratory motion due to at least one vibration promoter (Se) such that, owing to a vibration component which is normal relative to the conveying track, the frictional force (R) between the items (T) to be conveyed and the conveying track (Fb) is reduced. In order now to be able to achieve narrow band widths for the apparatus, while dispensing with the hitherto necessary chicanes for producing an orderly arrangement, the vibration amplitude of the normal vibration component, seen in the conveying direction (Ri) of the conveying track, is to increase, the vibration time remaining the same. This results in different friction conditions with an increase in the conveying rate in the conveying direction (Ri). The desired separation of the bulk goods is obtained owing to the increasing conveying rate. <IMAGE>

Title: Reusable formwork for the composite supports and back-filling method
Inventor: MUELLER JOACHIM DIPL ING
IPC: E21D11/04
Filed: 1983-07-22
Abstract: In underground mining and tunnelling, the roadways are secured with rigid or yielding steel supports. The hollow space remaining between the support arches and the rock is filled with back-filling material which can be moved up, preferably via pumps, even over relatively large distances. The intermediate space remaining between the support arches is sealed off by means of formwork elements which consist of individual supporting pads overlapping one another or sealed off from one another in the peripheral direction of the roadway. These supporting pads in turn are formed from several hollow bodies which bear tightly against one another and against the support arches. The use of tubular hollow bodies provides a uniform and even surface. The hollow bodies are compressed-air spaces which are connected to one another or are even separate from one another and which are braced by passing air in between the support arches as well as the lagging mats and the strutting or corresponding holders. <IMAGE>

Title: Pump as accessory for hand drills
Inventor: TAAKE BERTHOLD
IPC: F04C15/00
Filed: 1983-11-09
Abstract: In the pump shown in Figure 2, the cover 9 positioned inside the pump housing 6 is arranged to be axially movable on the drive shaft 3 and is secured on the drive shaft 3 by a screw cap 10. After start-up of the pump and the resulting internal pressure on the vanes of the vane rotor 1, the external pressure of the cover 9 on the vanes is no longer required. To this end, the screw cap 10 is loosened by a predefined distance, as a result of which the cover 9 can move axially outwards, and as a result the friction of the vanes is reduced, as is the loading of the hand drill. The necessary sealing effect is achieved by the internal pressure caused by the flowing medium. <IMAGE>

Title: Apparatus for machining welded areas of butt-welded, cylindrical bodies
Inventor: FRERKER JOHANNES
IPC: B23D79/02
Filed: 1983-11-14
Abstract: The apparatus serves to machine welded areas of butt-welded, cylindrical bodies and is provided with a clamping device holding the bodies in position coaxially to a clamping axis. So that the welded area can be machined exactly concentrically to the clamping axis, provision is made for three cutters (14) to be arranged in an axially symmetric manner around the clamping axis (5) and to be displaceable at right angles towards and away from the clamping axis (5). Each cutter (14) is mounted with its axis (12) of rotation in a bearing (11) in such a way that it can be rotated and driven essentially parallel to the clamping axis (5), each bearing (11) being pivotable about a pivot axis (10). The pivot axes (10) lie in a plane intersecting the clamping axis (5) at right angles and are orientated at right angles to the displacement path of the allocated cutter (14). Furthermore, each cutter (14) is closed off at the ends by a freely rotating roller (13) and has an increasing diameter towards its longitudinal centre. In this arrangement, the maximum cutter diameter (15) is at least equal to the diameter of the rollers (13). In addition, the cutters (14) together with their bearings (11) can be rotated about the clamping axis (5). <IMAGE>

Title: Cone crusher
Inventor: MEYER JOSEF
IPC: B02C2/04
Filed: 1983-11-14
Abstract: In cone crushers with a cone brake arranged between the crusher cone and the eccentric bushing and consisting of a torsion element fixed in the neck portion of the supporting and crushing cone and connected to an overrunning clutch arranged on the displacement piston in the cone shaft, the torsion element, when constructed as a wire cable, can be broken because of the high torsional and bending loads on the torsion element of the cone brake. On the other hand, the conventional torsion elements consisting of steel rods are relatively secure against breakages but are difficult to produce, insufficiently flexible, and entail high costs. These disadvantages are, however, eliminated according to the invention, where the torsion element, arranged between the neck portion (1) of the supporting and crushing cone (2,14) and the overrunning clutch, consists of a cable (3) which is externally surrounded at least partially by a reinforcing element (17). <IMAGE>

Patent DE-3346366-A1 (DE)
Inventor: HERR KLAUS-DIETER DIPL ING
IPC: E05F15/00
Filed: 1983-12-22
Abstract: A safety circuit for a window lift driven by an electric motor is described which causes a reversal in the direction of rotation of the drive motor when the window pane impinges on an impedance in its upward motion. The reversal criterion used is the motor current surge familiar to the state of the art. The circuit of the invention is characterized in that upon actuation of the "close" window key, the drive motor first rotates briefly in the direction of opening and thereby displaces the window pane downwardly, whereupon it is automatically reversed and only then does the pane motion toward the closed position begin. Consequently, the motor start-up peak current decays in that range of displacement of the window pane which is below its initial position, whereby an increase in current (di/dt) after resuming the initial position of the window pane at once causes motor reversal. Thereby, an already wedged hand or the like is prevented from being pressed with the full motor force briefly immediately upon the actuation of the "close" window key.
