Patent DE-3041029-A1 (DE)
Title: Bottom pour sliding stopper, esp. for arc melting furnaces - where guide rails force stopper plate upwards against bottom end of outlet nozzle
Inventor: LOTHMANN JOSEF
IPC: C21C5/52
Filed: 1980-10-31
Abstract: In the base of a melting furnace is an outlet nozzle, the bottom end of which is closed by a mobile stopper plate made of a refractory material. The plate is located on the free end of the piston rod of a work-cylinder, which is employed to retract the plate, thus opening the nozzle. The work cylinder is located on a pivot mounting, and an inclined guide rail is located below the nozzle and on each side of the outlet hole. When the plate is moved forward to close the outlet hole, the inclined guide rails force the plate upwards against the nozzle. The plate is pref. located via pivots in a two-pronged fork mounted on the end of the piston rod. An arc furnace with a bottom pour outlet nozzle needs no tilting mechanism. The invention provides a simple and reliable stopper for such furnaces. The stopper has a small size, and is easily opened and closed, e.g. when filling ladles.

Patent DE-3042552-A1 (DE)
Title: Pebble bed reactor side reflector - has block arranged to give uneven inner face thus reducing retarding effect
Inventor: ELTER CLAUS DR
IPC: G21C1/07
Filed: 1980-11-12
Abstract: A side reflector for a gas-cooled nuclear reactor is in the form of a hollow cylinder built up of graphite blocks; outward thrust from this cylinder resulting from the internal pressure of the pebble bed core is resisted by supports or props bearing against the surrounding thermal shield and liner. The faces of the reflector blocks which are towards the inside and thus constitute the inner face of the side reflector are at varying distances from the central axis of the reactor. Used for a gas-cooled pebble-bed reactor. It is found that the retarding effect exerted by the side reflector upon the descent of the fuel elements during the life of the core is highly attributable to the orderly arrangement of fuel elements in the outer layers of the core which becomes established after a certain period. By arranging for different blocks to project into the core space by slightly differing amounts, this orderly effect is broken up and thus the retarding effect upon the descent of the fuel elements is considerably reduced.

Patent DE-3047733-A1 (DE)
Title: Metering chute for silos - with linkage and cam disc coupling sliding inlet to hinged outlet cover
Inventor: BROECKER HEINRICH
IPC: B65D90/62
Filed: 1980-12-18
Abstract: A metering chute for the discharge of measured batches of mixed animal fodder (silage) from silos is fitted with a sliding cover at the inlet end and a hinged cover at the outlet end. An articulated linkage with a cam disc and a manual lever ensures that the outlet cover is closed when the inlet cover is to be opened and remains locked in the closed position until the sliding inlet cover is fully open. It is only opened by gravity when the inlet cover has been shut. This is a simple and robust device which meters accurate fodder quantities and functions reliably.

Title: Device for severing extruded profiles, in particular continuously produced pipes
Inventor: SCHNEIDER WERNER
IPC: B23D21/04
Filed: 1981-02-07
Abstract: In the case of a device for severing extruded profiles, in particular continuously produced pipes, there are severing tools in a frame, which accommodates the severing device, can be clamped onto the profile leaving the extruder and run along with the said profile in the axial direction during the severing operation, which severing tools rotate about the profile and are moved by means of a thrust ring radially against the profile circumference, the guiding of the thrust ring being performed with the aid of feed rollers which are held on a rocking lever and act laterally on the circumference of the said thrust ring. In order to bring about a uniform circumferential speed, with little wear and least possible generation of noise, over the entire width of the running surfaces of the feed rollers on the thrust ring, where there occurs a rotation accelerated from a standstill to the final speed and a loading of the feed rollers, the feed rollers acting laterally on the circumference of the thrust ring are conically shaped and the running surfaces of the thrust ring are bevelled off at an angle corresponding to their conicity.

Title: Fuel injection nozzle for internal combustion engines
Inventor: FUESSNER PAUL DIPL ING
IPC: F02M61/20
Filed: 1981-10-08
Abstract: A fuel injection nozzle for internal combustion engines is proposed, which has a valve needle (14) opening outwards and in which a throttle gap controlled by the lift of the valve needle (14) is associated with the injection aperture, which gap during a first partial lift of the valve needle (14) limits the quantity of fuel delivered. The injection nozzle is also provided with means (50, 70, 72) for generating a closing spring force with non-linear spring characteristic, which at the point corresponding to the end of the first partial lift of the valve needle (14) has a distinct bend. These means may advantageously be formed by a truncated cone spring (50) with rectangular, upright spring cross section or by one or two sets of disc springs (70, 72). In addition to these means a damping device (42, 46) is provided, which acts only during the opening lift of the valve needle (14) and is inoperative during its closing stroke. In this way the time curve for the opening lift of the valve needle (14) can be made largely independent of the quantity of fuel delivered. <IMAGE>

Patent DE-3143382-A1 (DE)
Title: Wooden block for a surface covering formed from wooden blocks capable of being laid by being put together individually, preferably for a floor covering
Inventor: SCHWARZ HEINZ
IPC: E04F15/04
Filed: 1981-11-02
Abstract: The invention relates to a wooden block for a surface covering formed from wooden blocks capable of being laid by being put together individually, preferably for a floor covering. A floor covering, in particular a wooden-block paving, consists of solid wooden blocks which are cut so as to be sharp-edged and are laid to form individually paved surfaces. Owing to the hygroscopic behaviour of wood, the floor covering is subject to fluctuations in expansion. The compressive stresses produced thereby in the wooden-block paving can lead to wooden blocks situated in the edge region being sheared off from their adhesive bond. To avoid this, a tight laying of the wooden blocks is to be striven for, i.e. the wooden blocks should extend as far as possible from one wall to another in an interior room. However, this has the disadvantage that the wooden floor covering is hindered in its free "working", resulting in compressive stresses which can even lead to displacement of the room walls. To avoid this displacement of the room walls and nevertheless permit a "tight" laying of the wooden paving blocks, provision is made according to the invention for a wooden paving block to have a recess which reduces its cross-section. This has the advantage that the wooden block can break if strong compressive stresses occur within the wooden-block paving, as a result of which the compressive stresses are reduced and building damage avoided.

Title: Control circuit for an electric motor
Inventor: ZEITVOGEL HEINRICH ING GRAD
IPC: H02P25/14
Filed: 1982-06-30
Abstract: A controllable rectifier (21) which reduces the conducting period in the event of a motor (20) being overloaded is connected in the circuit of the motor (20). In order to make it possible for the current flow control to be carried out using simple, commercially-available purely electrical means, a measuring resistor (22) is connected in series with the motor (20) and the controllable rectifier (21). The measured voltage present on the measuring resistor (22) is supplied to a threshold value switch (23) whose threshold value is set such that, if a predetermined rated load of the motor (20) is exceeded, a downstream-connected current flow actuator (25) sets a reduced conducting period on the controllable rectifier (21). <IMAGE>

Filed: 1982-09-23
Abstract: A device for warning of drivers driving in the wrong direction can be switched in such a way that a vehicle which goes into a (motorway) exit in the wrong direction is perceived by two corresponding reflex photoelectric beams or similar sensors, whereas vehicles driving correctly are ignored. The device can be implemented with discrete elements or with corresponding equivalent circuits and is to be battery-operated for reasons of economy. In each case an unmistakable audible and a visual warning signal must be agreed for this.
