Patent DE-3010845-A1 (DE)
Title: Ignition of sinter mixt. on travelling grate - below furnace hood contg. burners aligned at specific angles to reduce fuel consumption
Inventor: BONNEKAMP HORST DR ING
IPC: F27B21/06
Filed: 1980-03-21
Abstract: A mixt. of raw material and solid fuel travels along a grate or belt below a furnace hood, with closed side and end walls, and a closed roof. In the inlet end wall of the hood are burners fed with a stoichiometric mixt. of fuel and O2 to provide hot combustion gases low in O2 content in the upper part of the hood. In the exit end wall of the hood are other burners fed with excess O2 so the combustion gases in the lower part of the hood are cooler and have a higher O2 content, pref. above 5% free O2 obtd. using an air ratio of 2-5. The pref. hood contains inlet burners directed upwards at max. 30 and pref. 5-10 deg. from the horizontal, whereas the exit end burners are aligned downwards at max. 50 and pref. 20-35 deg. In the hood, the combustion gases travel in a closed loop, reducing fuel costs. The initial capital cost of the hood is also reduced.

Title: Remote controlled transistor inverter - has starter with relay cutting off stabilised starting voltage to control unit after time delay
Inventor: MANCHEN JOACHIM DIPL ING
IPC: H02M7/53846
Filed: 1980-03-21
Abstract: The remote controlled transistor inverter designed for a stable output while receiving an unstable input, has a transformer with a set of secondary windings with two windings connected to a control unit and acting as a source of actual value control signals. The unit has further connections for pulse control signals for the transistors. Connected to the input of the inverter is a starter unit with a resistance connected in a line to the control unit, and also to a Zener diode and capacitor to obtain a stabilised starting voltage. The line between the resistance and the diode also passes through a contact operated by a relay, so that after a delay, the starting current to the control unit is cut off. This line is also connected to a thyristor and trigger diode arrangement in the path of the relay.

Title: Brush mfr.machine with accurate positioning of drum holder - has precision coupling ensuring workpiece holder moves accurately to next processing station
Inventor: ZAHORANSKY HEINZ DR
IPC: A46D3/04
Filed: 1980-03-26
Abstract: The workpiece holders (9) for the brush bodies (8) are supported on a rotatable drum (3) or the like which executes both a positioning movement for the processing steps and an advance motion from one processing station to the next. A precision coupling (10) for the drum is provided at least for the first processing position following an advancing movement. This coupling can be formed by two interengaging mutually centering parts. One part is connected to the drum and the other to the machine frame (2) or similar fixed element. This coupling holds the drum in the precise processing position to prevent mechanical breakdowns through faulty positioning.

Title: Rotary inductor for electrical machine - has permanent magnet rotors with magnets arranged radially with intermediate tapered pole pieces
Inventor: POPOV ENTSCHO NIKOLOV DIPL ING
IPC: H02K1/27
Filed: 1980-04-29
Abstract: The rotor comprises a shaft on which laminated pole pieces (2) are assembled, on suitable keys. In the interpolar space the permanent magnets (4) are located. The axis of magnetisation is tangential to the rotational axis of the rotor. The magnets are held in position by an axial strip (5) with a T-head at each end. The strip bears against a lip (3) on each pole and thus supports the magnet against radial forces. The method of construction eliminates the need for attaching support brackets to the poles. Thus both manufacturing time and space in the machine are saved, the latter allowing greater output from a given rotor size. There is also a reduction in the number of components.

Title: Shortened cam assembly for flat-bed knitting machines - with dual-function tuck-loop and stitch cams
Inventor: BEYER GUNTER
IPC: D04B15/36
Filed: 1980-05-19
Abstract: In a cam assembly for use, partic. on dual flat-bed knitting machines with circulating carriages, for the formation of tuck-loop structures, the tuck-loop cam forms part of the transfer cam and a section of the return cam forms a stitch cam. The transfer cam is situated above the tuck-loop cam, and a switching cam is provided before the tuck-loop cam and the transfer cam. This arrangement enables a shorter cam carriage to be used, which increases the machine productivity.

Title: H.F. screening for electrical systems - has connectors with mu-metal screen to reduce magnetic reluctance between inner and outer surfaces of screen
Inventor: FOWLER ELIOT PARICK
IPC: H01R13/646
Filed: 1980-08-14
Abstract: The device provides an interconnection between two parts of an annular electrically conductive screen and incorporates an arrangement for reducing the magnetic reluctance of the magnetic path between the inner and outer surfaces of the screen in the region of the interconnection. Improvement in connector screening is possible by separation of the two contact rings combined with a reasonable length of separate conducting paths. Further improvements can be made by insertion of a high permeability magnet material such as a small toroid of laminated mu-metal between the conducting paths.

Title: Controlled braking system for rail vehicle - uses markers along track with lengths corresponding to square of distance to target stopping point
Inventor: BETZER HELMUT
IPC: B61L3/00
Filed: 1980-11-28
Abstract: The controlled braking system compares signals obtained from alongside the track with signals representing the train retardation. A series of markers are arranged at spaced points along the track preceding the required stopping point, the length of each being proportional to the square root of the distance between the marker and the target stopping point. The braking system is released when the time taken to travel past a marker is less than the duration of a timer which is proportional to the square root of the reciprocal of the retardation. The braking system is robust and is not affected by climatic variations.

Title: Flow regulator for air conditioning plant - has in-line configuration for duct insertion with solenoid setting facility
Inventor: SOETHOUT FREDDI ING GRAD
IPC: G05D7/01
Filed: 1980-12-18
Abstract: The flow regulating valve for installation in air ducts has a facility for setting using an electromagnetic element and is designed for ease of serving. Flow passes from inlet (11) through the inserted regulator (2) to an outlet. The flow is fixed by the gap (14) between a moving poppet (7) and the body (2) of the unit. The poppet is supported on a diaphragm (8) that is capable of deflection up to a maximum (x). The position of the poppet may be adjusted by supplying power (30) to a solenoid (20) to set the position of the threaded (25) insert.

Title: Device for unlocking and locking doors
Inventor: RATHMANN KLAUS DIPL ING
IPC: E05B65/38
Filed: 1981-05-29
Abstract: A device for unlocking and locking doors has a motor (22) controlled by direction of rotation for the purpose of generating underpressure or overpressure for the actuators and a change-over switch (11) dependent on the system pressure. The motor (22) can be activated by at least one door switch (2).
