Patent DE-3115765-A1 (DE)
Title: Combined battery-dynamo lighting system on a bicycle
Inventor: UEBERDICK ALTFRIED
IPC: B62J6/00
Filed: 1981-04-18
Abstract: The combined battery-dynamo lighting system consists of the commercially available dynamo lighting system which is present on the bicycle and is complemented by the battery system. The battery system includes a battery box with two parallel 4.5 V pocket lamp flat batteries, a switch-off element, an SH B 1280-BY 250 7K diode and two 3.8 V pocket lamp bulbs. The diode which is positioned in the lamp between the dynamo and pocket lamp bulb prevents the battery flow to the dynamo which flows via the rear light into the existing lighting system when the battery system is switched on in order to be weakened or produced there. The dynamo acts at the same time as a resistor which reduces the alternating dynamo current of 6V 3W to a pulsating direct current of 3.8 V. It is thus ensured that the pocket lamp bulbs in the back light and in the lamp are not burnt out in dynamo mode and/or battery mode.

Title: Method and device for recovering heat from exhaust air of driers which contains water vapour
Inventor: KREMER ROBERT
IPC: F28D21/00
Filed: 1981-06-06
Abstract: In the recovery of heat from exhaust air of driers which contains water vapour, in particular in the chemical (synthetic, man-made) fibre and textile industries, a colder medium is heated with the aid of the exhaust air by means of heat exchange. In order to achieve a substantial improvement in the efficiency of the recovery of heat, use is made as the colder medium of continuously running service water which is trickled in an absorber container (1). In order to provide an extremely large surface, the amount passed through is repeatedly and continuously recirculated by a pump and the trickling process is carried out in at least two stages (3, 4). The exhaust air coming from the drier (2a) is cooled by direct contact with the trickled water vapour, and the water vapour contained in the exhaust air is condensed on the surfaces of the strands of water. The cooled and dried exhaust air can subsequently be fed again to the drier. <IMAGE>

Title: Rotor drive
Inventor: KLIMASCHKA MARTIN
IPC: H02K53/00
Filed: 1981-06-12
Abstract: Two rows of magnets are provided on a wheel or on a drum and are arranged such that the magnets of the second row are chronologically between two magnets of the first row. All the magnets have the same polarity. A magnet of opposing polarity is fitted in front of the wheel and can be displaced or can swing from one row of magnets of the wheel to the other so that it first attracts a magnet in the one row and subsequently a magnet in the other row. As soon as the magnet of opposing polarity has attracted a magnet in one row of the wheel, it is given a displacement to the other row by means of lever control, the same attraction process always taking place and the wheel being caused to rotate. The displacement can be effected, for example, by means of a cam disc. In order that the wheel does not rebound or stop, it is provided for a number of such rotors to be arranged on one wheel shaft (axis), the operating cycles of which rotors differ from one another in time.

Patent DE-3139426-A1 (DE)
Title: Device for the automatic stitching of the selvedges of cuffs, collars and similar sewing material
Inventor: SCHIPS HELMUT
IPC: D05B35/10
Filed: 1981-10-03
Abstract: For the automatic stitching of the selvedges of cuffs, collars and similar sewing material by means of a sewing machine, according to the invention the sewing material is sensed in front of the needle in order to determine the approach to a corner of the sewing material. The sewing machine is stopped at the start of the corners, and the sewing material is grasped by a turning device and turned in a plurality of angular steps in the direction of the next straight selvedge seam. At each part turn, a number of stitches are made. The control is carried out by means of a microcomputer, to which the number of part turns and the number of stitches to be made for each part turn are entered, with the result that the radius of curvature of the seam at the corner is determined. The microcomputer calculates the angle of the part turns. To achieve an exact position of the start of the seam curvature at the corners, the sewing speed is reduced before the corner is reached, and the stitch length can be varied in order to achieve a positioning down to a fraction of a stitch length.

Title: Three-part central control valve for water treatment plants with separate channel and regenerator stock container refilling valve
Inventor: DESCH KURT MICHAEL
IPC: F16K11/07
Filed: 1981-12-03
Abstract: The central control valve comprises an operating valve (13) which has the connection cross sections throughout and a regeneration or channel valve (14). On either side, the operating valve has two outlets (15) which can be shut off and lead to the top (24) and bottom (23) of the treatment container. Situated between these outlets (15) are the untreated water connection (4) and the process water connection (5) which are separated from one another by the third shut-off valve (17) during the treatment operation. The channel valve (14) is connected (24-22, 23-21) to the operating valve (13) on either side behind the two outlets (15) of the latter which can be shut off. In the operating valve body (13) no rinsing and refilling water is, therefore, fed to the treatment container from one side to the other side of the outlets (23, 24), that is to say not even via the untreated water and process water connections (4, 5). As a result of dividing the valve body into channel valve (14), operating valve (13) and treatment container connection (10) consisting of treatment container attachment (11) and water conduit channel (12), a water meter housing for a commercial water meter insert can be integrated into the valve as a whole in place of the water conduit channel (12).   <IMAGE>

Patent DE-3206149-A1 (DE)
Title: Multi-stage turbine rotor
Inventor: GLASS BENJAMIN GORDON
IPC: F01D1/36
Filed: 1982-02-20
Abstract: A multi-stage turbine has an inlet disc assembly which feeds the working medium to an outlet disc assembly mounted on the same shaft. The assemblies are fitted between web plates which pass through the interior of a turbine casing, and the medium enters the casing and passes to the inlet assembly via nozzles in a nozzle ring arrangement connected to the casing. Each disc assembly comprises spaced discs with webs which guide the working medium first of all through the inlet assembly and then the outlet assembly. A central flow channel in the assemblies and in the region of the shaft carries the medium from the inlet to the outlet assembly. The medium flows out via outlets on the underside of the casing. In one version, the disc assemblies are conical and, as viewed from the side, the assemblies with the web plates have an X-shaped cross-section. In another embodiment, the inlet assembly is flat and the outlet assembly is conical and the casing of both embodiments is shaped in such a way that low losses and a maximum of strength are obtained. The nozzles can be arranged convergently/divergently and in an accumulation space situated adjoining the circumference of the inlet assembly.

Patent DE-3218570-A1 (DE)
Title: Electric toaster with an integrated roll grate
Inventor: KAISER HELMUT
IPC: A47J37/08
Filed: 1982-05-17
Abstract: The invention relates to an electric toaster with a housing, in which a toasting chamber is arranged and which has above the latter in its top side a bread insertion slot, there being articulated pivotably about horizontal axes on the top side of the housing a roll grate which is adjustable between a rest position folded onto the top side and a folded-up operating position. The aim consists in producing such a toaster which, with low manufacturing outlay, has an integrated roll grate which is easy to operate and can in particular be designed as a narrow single-slot toaster. This aim is achieved according to the invention in that the pivoting axes of the articulation points of the roll grate run transversely to the longitudinal direction of the bread insertion slot. The folded-down roll grate then projects if need be on the end side of the device and does not prevent the device being set up with its wide side along a wall. <IMAGE>

Patent DE-3219338-A1 (DE)
Title: Device for measuring the level of bulk materials in a container
Inventor: VELLING GUENTHER DIPL CHEM DR
IPC: G01F23/28
Filed: 1982-05-22
Abstract: In a device for measuring the level of bulk materials in a container, which is subject to overpressure and a raised internal temperature, with the aid of a transmitter arranged on one side of the container and a receiver arranged at a distance from the transmitter, the wall of the container is provided with at least two mutually opposite openings, one of which is provided for the transmitter and the other for the receiver. Both openings are in each case closed by a wall part of lower thickness, which has an annular cross-section. Expediently the wall parts of lower thickness are designed as cylindrical sleeves which are closed by a universal ball joint-shaped section. On the condition that transmitter, receiver and the wall parts of lower thickness are arranged flush with one another, the strength of the signals transmitted by the transmitter can be so weak that, even in the case of use of radioactive substances as transmitter, danger to the environment is excluded or avoidable by inexpensive screens. Moreover, transmitter and/or receiver can also be arranged outside the container, which is thick-walled apart from the openings, at a distance from the same if this is necessary, for example because of the temperature-sensitivity of the parts.

Title: New type of device and new type of control principle for the purpose of obtaining energy from moving air and moving water and other applications
Inventor: HISSEN PAUL DR
IPC: F03D3/06
Filed: 1982-08-14
Abstract: Device for obtaining energy from wind or water flow and the inversions of this principle, characterised in that resistance surfaces in a multi-armed rotor are pivotably mounted and when this rotor turns are constantly adjusted by way of a gear fixed on its static axis and a gear twice as large on the rotating axis of the resistance surface and connecting chain rotating in a ratio of 2 to 1, so that on the one side of the system a resistance surface rotated transversely to the flow always presents a high resistance to this and is therefore rotated, whilst on the other side an equal surface turned longitudinally to the direction of flow is directed against this without any resistance. All forms of transmission of the rotary movements are to be included, as are speed ratios, all types and forms of resistance surface, all forms of transmitting the rotary energy, all possible control devices and the use of the inversions of the principle for the purpose of movement of gases or liquids and of vehicles of all types.
Patent DE-3230330-A1 (DE)
Title: Process and device for controlling a machine assembly which can be pivotably attached to a vehicle
Inventor: REICHHARDT ANDREAS
IPC: A01D41/14
Filed: 1982-08-14
Abstract: Known processes and devices for controlling a machine assembly which can be pivotably attached to a vehicle usually permit only one largely non-continuous control and are characterised in that the machine assembly moves relatively freely over the floor at a height which cannot be precisely defined, for example in the case of a cutting mechanism of a combine harvester. In addition, the response speed is delayed by using mainly mechanical switching and transmission elements which require a considerable amount of space and in which friction losses unavoidably occur. In the control according to the invention, the number of mechanical switching elements is reduced to a minimum so that friction influences are negligible. The essential difference with respect to known controls consists however in the fact that a desired value/actual value comparison is carried out, the tolerance or sensitivity of said comparison being adjustable, and that a continuous control of the height adjustment of the machine assembly above the floor and a rapid and automatic matching to the floor conditions are possible.

Patent DE-3302855-A1 (DE)
Title: Inner fin tube for heating boilers heated by compressed gas or compressed oil
Inventor: HEIM KURT
IPC: F28F1/40
Filed: 1983-01-28
Abstract: The inner fin tube consists of one-piece shell strips (2) which are multiply finned in the longitudinal direction and welded to one another on the longitudinal sides, each shell strip (2) having a lateral limb (4) on each longitudinal side. The shell strips, which are cut to length from a strand, are bent at right angles to their longitudinal direction to form a circular segment having the desired outside diameter of the inner fin tube, so that the mutually adjacent fins (3) converge towards one another. In order that the lateral limbs (4) can also be bent as perfectly as possible, their width is expanded to the fin spacing at the foot of the fins and each shell strip, which has so far had, e.g. five fins, is provided from now on only with four fins or one fin less. In the weld gap (5) between the two shell strips (2), a fin (7) which seals the weld gap is welded in from outside by means of a special pressing device (9), so that two shell strips and, at the same time, the pressed-in fin (7) are welded to one another in a liquid-tight fashion from outside in one welding operation. <IMAGE>
