Title: Cutting tool of a can opener
Inventor: DABUI HUSCHANG
IPC: B67B7/46
Filed: 1982-11-22
Abstract: Cutting tool of a can opener, which is cut out, recessed, bent and curved from a piece of steel sheet or other materials so that all of the elements necessary for cutting, shearing and pressing of the cutting operation, such as cutting knife (1) with initial-cutting tip (1c) and cutting edge (1a), guide faces (2b), slide face (2c) and lever support point of the leverage (2a), and also fastening-body part (3) necessary for fastening the cutting tool to or on a handle or appliance, are accommodated on three planes situated perpendicularly to one another, or two which are parallel. A can opener constructed with this cutting tool cuts the can base of a can closed by overfolding, with a small force and without deformation, so that the cutting line made is maintained and lies close to the folded edge, and the cut-out part of the can base is easily removable. In addition, this can opener can be cleaned very easily and thoroughly after use and is inexpensive to manufacture. <IMAGE>
Patent DE-3244199-A1 (DE)
Title: Conversion rig
Inventor: JUNG OTTO DR MED
IPC: B63B35/79
Filed: 1982-11-30
Abstract: The known conversion rigs have in common the disadvantage that the shaping of the handle strips cannot be optimally adapted to the intended dual purpose both as a V-shaped control frame and as a boom.   This disadvantage can be avoided by a variable geometry of the handle strips. To solve the technical problem, according to Figs. 1 and 2 the two handle strips 1, 2 are split in the centre third and are provided with lockable joints 8, 9 or interchangeable push-in connections. A joint at the tip of the handle strips 1, 2 can be dispensed with here. The handle strips 1, 2 can serve as a V-shaped control frame for a wing rig when the front ends are spread apart and as a boom for a Schweitzer rig when the front ends are folded. Main use is flying with a windsurfing board. <IMAGE>

Title: Process for preparing domestic refuse and bulky refuse for incineration, and plant for carrying out the process
Inventor: ROESE KARL
IPC: B03B9/06
Filed: 1982-12-29
Abstract: In order to obtain, in a process for preparing domestic refuse and bulky refuse for incineration, at the same time the highest possible calorific value, good burning behaviour and low flue gas pollution, the domestic refuse is passed through a manual sorting station and a screening drum before it is combined with the comminuted bulky refuse. The overflow from the screening drum is then passed together with the comminuted bulky refuse through an Fe selector and the screenings are passed through a further Fe selector. With insertion of a composting station in the screenings path, the material streams thus prepared are homogenised in a mixer located upstream of the actual combustion chamber.

Title: Suspending ceiling covering
Inventor: MERKWITZ GUENTHER
IPC: E04B9/06
Filed: 1983-03-04
Abstract: The invention relates to a suspending ceiling covering made of visible T-shaped metal sections arranged in the form of a square or rectangle. Before mounting the metal strips on the ceiling, wooden strips are slid onto their lower transverse webs. In addition, the outer edges of the wooden strips are in each case interrupted at the intended crossing points to enable the transverse strips abutting on the main strip at right angles to be hooked in. The object of the invention is to provide a ceiling covering in which even already existing ceiling structures can be retrospectively provided with the wooden strips and the panels carried by them. The object of the invention is achieved in that grooved wooden strips are put, mutually opposite, onto the horizontal edges of the T-shaped sections already laid, and in that these wooden strips form a square or rectangular frame for each individual ceiling bay, the frames being separated from one another by concealed joints. <IMAGE>
Patent DE-3312124-A1 (DE)
Title: Transductor-controlled voltage stabiliser
Inventor: TSCHIRNER ERNST
IPC: G05F1/30
Filed: 1983-04-02
Abstract: On the three legs of a three-leg magnetic core (three-phase core), an exciter winding (18) and two secondary windings (32, 34) are located. The secondary windings (32, 34) are connected in opposite directions in series between an input and an output terminal (10, 14) so that their induced voltages have opposite phases with respect to one another. On the legs (24, 26) carrying the secondary windings (32, 34), control windings (36, 38), through which direct current flows, for generating a premagnetisation of the legs (24, 26) are arranged by means of which the magnetic flux generated by the exciter winding (18) can be displaced towards one or the other leg (24 or 26) so that an alternating voltage is generated predominantly in one or the other secondary winding (32 or 34). The currents through the control windings (36, 38) are controlled via a control error signal. The resultant voltage across the secondary windings (32, 34) corrects the input voltage. In another embodiment, two exciter windings similarly interact with a secondary winding. <IMAGE>
Patent DE-3318585-A1 (DE)
Title: Process for making a vacuum-tight bond, and a composite produced thereby
Inventor: BEISLER WALTER
IPC: C04B37/02
Filed: 1983-05-21
Abstract: The invention relates to a process for making a vacuum-tight bond between oxide ceramic and an electric conductor, and to a composite produced by such a process. Vacuum-tight bonds between oxide ceramic and metals have hitherto been made by soldering of metallised oxide ceramic or else by using active solders. For soldering, a defined atmosphere must be provided, and metallising of small bores is fairly involved; on the other hand, active solders are comparatively brittle. To avoid these difficulties, and for making a vacuum-tight bond inexpensively, it is therefore proposed that the electric conductor consist of platinum or a platinum alloy and be preferably inserted as a wire into the moulding of oxide ceramic and, moreover, be sintered in during the sintering of the oxide ceramic. In a composite produced in this way, the electric conductor is surrounded in a vacuum-tight manner by the oxide ceramic, high mechanical strength also being achieved.

Title: Single-phase annular rotary transformer
Inventor: OGANIAN USIK ARTASESOVIC
IPC: H01F38/18
Filed: 1983-09-27
Abstract: The transformer contains a stationary magnetic conductor and a rotating magnetic conductor, which are separated from one another by air gaps (IO, II) at the ends. A stationary annular winding (3) and a rotating annular winding (4) are arranged in the mutually facing end annular grooves of the magnetic conductors. The magnetic conductors are formed in layers from identical L-shaped core laminates. The long limb and the short limb of the core laminates (1) of the stationary magnetic conductor are located opposite the short limb and the long limb respectively of the core laminates (2) of the rotating magnetic conductor, as a result of which radial air gaps (8, 9) having a high magnetic conductivity are formed at various distances from the rotation axis. <IMAGE>
Patent DE-3339058-A1 (DE)
Title: Exposed tightenable tension member comprising one or more tension elements, such as steel rods, wires or strands
IPC: E04C5/12
Filed: 1983-10-28
Abstract: In the case of a tension member (1), in which the tension elements (2) are arranged inside a sheathing (5) and are surrounded by hardening material (12), such as cement mortar or the like, introduced into the sheathing, the sheathing (5) is designed on its inner side in such a way as to prevent a bond with the hardening material. The hollow space between the tension elements (2) and the sheathing is filled with a plastically deformable anti-corrosive material in an area directly adjoining the anchor plate (4). In addition, the sheathing (5) is telescopically joined to a further sheathing (7), which is firmly connected to the anchor plate (4). In the joining area of the two sheathings (5, 7) there is arranged a piece of pipe (9) and the annular space formed between the latter and the sheathing (5) is filled with a plastically deformable anti-corrosive material. As a result, a bond between the hardening material and the inner side of the sheathing is prevented and the hardening material is given the chance to expand, so that when the tension member is retightened it can stretch with the hardening material without causing compulsive forces to be transferred to the sheathing. <IMAGE>

Patent DE-3346990-A1 (DE)
Title: Filter arrangement in front of the lens of enlargers
Inventor: JAHN KARL
IPC: G03B27/73
Filed: 1983-12-24
Abstract: In order to avoid disadvantages which arise in the use of individual filters when controlling the contrast of gradation-changing papers and when filtering colour pictures, filter selection discs are mounted rotatably and in an easily exchangeable fashion on the lens of the enlarger. This facilitates quick and convenient change of filter. A high convenience is achieved, in operation for low outlay. A further saving in material can be achieved, in conjunction with a flexible filter assignment matched to the respective conditions, when the filter selection discs are assigned round or rectangular, or possibly framed filters. When three filter selection discs are assigned density filters in the subtractive primary colours together with one white light spot each, any black and white enlarger can be converted to a colour enlarger.

Patent DE-3412417-A1 (DE)
Title: Circuit arrangement for converting sound signals into electrical signals in a two-terminal network
Inventor: HOPP ACHIM PROF
IPC: H04R3/06
Filed: 1984-04-03
Abstract: An electrical two-terminal network in a microphone/loudspeaker arrangement is described which contains a microphone (3) with variable capacitance and a differential amplifier (4) controlled by it. A voltage which consists of a constant voltage independent of the feed voltage of the two-terminal network and a superimposed alternating signal voltage is applied to the inverting input (9) of the differential amplifier. The constant voltage is derived from the forward voltage of a diode (17). The differential amplifier is provided with feedback in such a manner that a voltage which is proportional to the voltage at the inverting signal input is dropped across a resistor (11) connected to its output. The direct current flowing via this resistor forms the majority of the quiescent current of the two-terminal network. The quiescent current, which also flows through the connected loudspeaker is thus largely independent of fluctuations of the feed voltage. <IMAGE>
