Title: Centrally controlled lighting installation for public buildings - has switches for individual lights allowing their operation independently of central switch
Inventor: CHRISTIANSEN DIETER
IPC: H05B39/04
Filed: 1980-11-12
Abstract: The lighting installation includes a normally-closed central switch (2) which can be opened against the action of a spring, to break the circuit to the lights (3,5,7). A first individual light switch (4) for the light (3) can be operated locally by an operating lever (12) in addition to being operable by attraction of a lever arm (11) by an electromagnet (11). If the central switch is opened briefly, the interruption of the magnetic field of the electromagnet causes the switch (4) to open due to gravitational force on the arm (11). Once the central switch is closed again, the switch contact (10) is opened so the switch (4) does not close again unless the lever (12) is used to close the contact (10). On the other hand, the switch (4) can be opened, even if the central switch is closed, by operating the operating lever (12) to pivot the arm (11) away from the electromagnet. A second individual switch (6) for lights (5) acts similarly to the first but uses an external lever arm (15) and a spring-urged normally-closed switch element (17) connected in series with the electromagnet (14).

Filed: 1980-12-19
Abstract: Two-part cover for a washing machine drum with a peripheral charging opening has both cover parts hinged and spring loaded in the outward swinging position. The first part of the cover is smaller than the charge opening and can be swung through it. The second part is broader than the opening and has an elongated eye which snaps over a hooked rocker on the first part. Ledges along the underside of the second part are arranged close to the edges of the charge opening and prevents clothes from squeezing through the gap during the spin operation. This prevents inadvertent opening of the cover and facilitates its manual operation.
Patent DE-3105517-A1 (DE)
Title: Composite superconductor
Inventor: ANDO TOSHINARI
IPC: H01F6/06
Filed: 1981-02-11
Abstract: A novel composite superconductor is disclosed which is formed from a superconductive material and a normal conductive material. The composite superconductor has a number of closely adjacent grooves on one surface which is in contact with a coolant and a number of ridge-like elevations which are spaced apart by the grooves and have pointed ends. The surface of the grooves and of the ridge-like elevations is coated with a thin film of a metal or of its compounds which have a higher thermal resistance than the surface of the composite superconductor. Consequently, a highly critical heat flow can be achieved during film boiling and a high cooling capacity can be achieved, and the cross-sectional area of the normal conductive material can be reduced, the effective current density increased and the dimensions of a magnet reduced.

Filed: 1981-03-06
Abstract: The invention relates to internal mould-release agents containing aqueous isocyanate emulsions comprising     A) 80-20% by weight, based on the entire emulsion, of water, B) 18-79% by weight, based on the entire emulsion, of an organic polyisocyanate, and optionally, C) 1-10% by weight, based on the polyisocyanate, of a nonionic surfactant as emulsifier,  which are characterised in that they contain D)0.5-5% by weight, based on the entire emulsion, of a diester of o-phosphoric acid, of the formula <IMAGE> in which R denotes identical or different aliphatic, straight-chain and/or branched hydrocarbon radicals, each having 1 to 7 carbon atoms.   The polyisocyanates used are principally aromatic polyisocyanates or NCO prepolymers derived therefrom, but in particular polyisocyanates which are the product of the phosgenation of the undistilled bottom fraction after removal of diaminodiphenylmethane components from an aniline-formaldehyde condensate or the undistilled bottom fraction after removal of diisocyanatodiphenylmethane components from the crude product of the phosgenation of an aniline-formaldehyde condensate. The di(C1-C7-alkyl) orthophosphate, preferably di-n-butyl phosphate, acts as mould-release agent. The isocyanate emulsions are used as binders, preferably in a process for the production of chipboard from lignocellulose-containing materials, and allow repeated use of the moulds without cleaning.

Patent DE-3110082-A1 (DE)
Title: Convector
Inventor: MOEHLENHOFF ANDREAS
IPC: F24D3/14
Filed: 1981-03-16
Abstract: The invention relates to a convector having a heater (8) for an arbitrary heating medium. The heater (8) is accommodated in a groove (5) which in the base region has an interspace (13) in which air to be heated is blown by a fan. The air can escape from the interspace (13) only through a gap (17) situated at the upper rim of the groove (5), and is blown in the manner of an injection below the heater (8) and through the latter. Because of this forced flow, the convector is particularly suitable for low-temperature operation. <IMAGE>
Patent DE-3122124-A1 (DE)
Inventor: FRANK SIMON DIPL ING
IPC: B60N2/90
Filed: 1981-06-04
Abstract: A device for supporting a moveable seat, for example a seat in a motor vehicle, by means of sliding rails which can be displaced in their longitudinal direction on roller facilities situated between the sliding rails and stationary alignment rails, the position of the seat being set by a mechanism which arrests the movement of the seat and involves, if desired, notches on at least one alignment rail, made such that it can withstand excessive loading, at the same time being simple and inexpensive to manufacture and install. This is achieved by having both the sliding rail and the related alignment rail feature at least one flange projecting out at the side, such that the flange on the sliding rail lies a short distance below the flange on the alignment rail resulting in flanges coming into contact under overload conditions. The facing flanges feature surface projections which interlock when under load.

Title: Solar cell generator, particularly in plate form
Inventor: CUEVAS FERNANDEZ ANDRES
IPC: H01L31/048
Filed: 1981-07-25
Abstract: The invention relates to a solar cell generator in which the cells, which are electrically connected to one another, are combined to form one plate in a carrier. The cells are constructed with two ends and are located between two transparent plates held by the carrier so that light can be incident on both ends of the cells. Instead of one transparent plate, a reflecting plate or a reflecting store can also be provided which throws reflected light onto the cells. The efficiency of such a solar cell generator is improved in comparison with a solar cell generator having cells which are only light-receptive from one side.

Title: Method and device for monitoring the oxygen saturation of the blood in vivo
Inventor: SCHULZ HANSRICHARD PROF DIPL P
IPC: A61B5/00
Filed: 1981-08-28
Abstract: In a method and a device operating according to this method for monitoring the oxygen saturation of the blood in vivo, the differing wavelength dependency of the absorption of light by the haemoglobin and by the oxyhaemoglobin is utilised. The ear lobe of the subject is transirradiated using time-division multiplex in an alternating fashion with red and green light. The transmitted intensity of the red and of the green light is determined by a photoelectric transducer whose output signal is tapped capacititively in order to eliminate the DC voltage component depending on the noise. The AC voltage signal is demodulated synchronously and displayed optically and/or acoustically. The result is a light, handy, battery-operated device which displays the instantaneous blood oxygen saturation relative to the stored initial value, and permits continuous monitoring of the oxygen saturation over a lengthy period.

Title: Expanding dowel for anchoring in bores which are produced such that they widen conically inwards
Inventor: FISCHER ARTUR DR
IPC: F16B13/00
Filed: 1981-09-03
Abstract: The invention relates to an expanding dowel which is suitable for anchoring in bores which are produced such that they widen conically inwards. The expanding dowel comprises a stay bolt which is supported on the base of the bore, and has an expansion cone and an external thread, onto the expansion cone of which an expansion sleeve can be driven, the expandable part of which comprises expansion lamellae formed by longitudinal slots. In order, on the one hand, to reduce the drive-in resistance and, on the other hand, to avoid slitting open of the dowel sleeve by the greater expansion of the expansion lamellae, the latter are delimited in the longitudinal direction by a peripheral groove arranged in the inner bore of the expansion sleeve.

Title: Set of structural elements for building a stairway, in particular from prefabricated concrete compound units
Inventor: HEIBGES BRUNO
IPC: E04F11/035
Filed: 1981-09-09
Abstract: The invention relates to a set of structural elements for forming a stairway (1), in particular from prefabricated concrete compound units, having treadboards (2) and supporting elements (3) for the treadboards which are approximately in the form of half-moons in plan view. By means of said set of structural elements, it is to be made possible to manufacture, from individual elements, stairways (1) which run in any progression, in particular outdoor stairways, which are simple to mount and easy to process, it being possible to produce the individual structural elements easily and cost-effectively, i.e. they are made up of geometrically very simple parts. This object of the invention is achieved in that the supporting elements (3) are designed as cylinder wall cutouts, having a bearing means on one end side (9) for a treadboard (2) and a bearing means (6) on the periphery of the outer wall (8) for the neighbouring treadboard (2) lying therebeneath. <IMAGE>

The axial longitudinal displacement of the coupling half takes place by means of a displacement of the bearing (21) or the axial displacement of the coupling shaft (19) in the bearing (21). The coupling operation can thereby be automated. <IMAGE>
Patent DE-3201386-A1 (DE)
Title: Steam motor operated with a refrigerant
Inventor: DIETZ GUSTAV
IPC: F01B29/12
Filed: 1982-01-19
Abstract: The steam motor has the task of converting the heat energy, in the form of a refrigerant vapour, obtained by the Rankine process into kinetic energy and of driving machines. Hitherto known steam motors have the disadvantage that they make insufficient use of the vapour energy, are too costly or are unsuitable for relatively high vapour pressures or relatively large temperature differences in the cold vapour region. The object was achieved by virtue of the fact that all the moving parts in the steam motor, as in a refrigerant compressor, are accommodated in a gastight crankcase with cylinders, that the cylinder cavities are assigned on the gas side to a gas exchange device which is arranged as a rotary slide valve control with easily replaceable rotary slides and a secondary drive in a control head which closes off the cylinder cavities on the side facing away from the crankcase, and that the secondary drive is in rotary connection with the crankshaft via an inverted tooth chain which is guided in a gastight well connecting the crankcase and the gas exchange device. <IMAGE>

Title: High-temperature oxygen probe
Inventor: KOERTVELYESSY LASZLO DIPL PHYS
IPC: G01N27/409
Filed: 1982-05-27
Abstract: In an oxygen probe, one of the two electrodes is constantly exposed to mechanical and chemical corrosion, the service life thereby often being substantially shortened. It is expensive to replace said electrode because it is made of noble metal. In the novel oxygen probe, said electrode is produced with the aid of a ceramic matrix in whose pores the desired electrode metal is incorporated. The novel electrode is cheaper, more durable, completely insensitive to pressure and chemically neutral, and it can also be used near the melting point of said electrode metal.

Title: Method and device for removing the slag and the burr from the edges of flame-cut flat workpieces, in particular sheet-metal parts
Inventor: RUNGGER HELMUT
IPC: B23P9/04
Filed: 1982-09-11
Abstract: The invention relates to a method and a device for removing the flame-cutting burr on the edges of flame-cut flat workpieces (e.g. sheet-metal parts), in which the slag beads projecting above the workpiece plane are broken off in a revolving movement parallel to the workpiece plane, and in addition the sharp edges are broken by striking in order to remove the remaining burr, the striking likewise being carried out simultaneously in a revolving movement. A method and in particular a suitable device for carrying out the method are provided by the invention, in which device the design cost is reduced compared with the known prior art, wear phenomena and operating faults due to jamming of the striking bodies are avoided and the performance is increased. This is effected by virtue of the fact that an oscillating movement directed parallel to the workpiece plane approximately at right angles to the feed direction of the workpiece is superimposed on the revolving movement for the striking and the removal of the burr, and the striking is effected by converting the rotary energy into work of deformation while utilising the centrifugal force acting on the striking bodies. <IMAGE>

Title: Apparatus for welding studs to a workpiece
Inventor: HEBERLE MANFRED
IPC: B23K9/20
Filed: 1982-09-22
Abstract: In an apparatus for welding studs to a workpiece, the problem occurs that the ignition tip available for striking a proper arc at the stud can be deformed or even destroyed when the welding current is switched on and the arc thereby struck. This is because the welding current is switched on in a conventional apparatus when a striking pin hits the piston of the apparatus with considerable momentum, at the front end of which piston the stud is pressed with the ignition tip onto the workpiece. According to the invention, the welding current is switched on before the striking pin hits the piston, and in fact with the aid of an appropriate control device which switches on the welding current by a sufficient time interval in advance and thus strikes the arc.

Title: Process for producing moulded concrete bricks
Inventor: PETER ROLF DIPL ING
IPC: B06B1/16
Filed: 1982-10-19
Abstract: In order, in the production of concrete products, to make it possible to reduce substantially the vibrating time or cycle time in relation to the respective consistency of a blank to be produced, without having to stop the machine and readjust it appropriately by hand for the necessary respective resetting of the optimum vibrating-force/ frequency ratio, it is to be possible to adjust the vibrating force continuously during the operation of the vibrator in order to set the particular optimum vibrating-force/frequency ratio. This can be carried out here by hand or else by computer control by means of an appropriate actuator. For this purpose, action is taken from outside by adjustment means on an unbalance flywheel in such a way that a centre of gravity can be adjusted continuously, during the rotation of the unbalance flywheel between a neutral position and a maximum unbalanced position within an adjustment travel X.

Title: Axle body for motor vehicle axles with bent-out portions bounded by wedge cut-outs
Inventor: NEUMANN BERTRAM
IPC: B21D53/90
Filed: 1982-11-04
Abstract: The invention relates to the field of motor vehicle technology. The object of the invention is an axle body which can be manufactured with a low degree of expenditure in terms of energy and which is economical in terms of material. The objective of the invention is to design an axle body with a wedge cut-out contour, in the region of which the extensions admissible for the respective material are not exceeded during bending out. The essential aspect of the invention consists in the fact that the box-shaped axle body contains cut-out shapes before bending out, the straight contours of which shapes extend parallel to one another in the region of the zones which are drawn during bending out and extend equidistantly to the junction radius r after bending out. The field of application of the invention is the design of axle bodies with a bent-out portion for receiving the axle drive.

Inventor: KLEIN HORST
IPC: A61C17/34
Filed: 1982-11-30
Abstract: The invention relates to an electrically operated toothbrush with oscillating motion, whose angle of oscillation can be adjusted. This is a easily achieved by the fact that the rotation of the electric motor producing the motion can be reversed by pole changing, and thereby the radius of the circular orbit of the bolt of a rotating shaft connected to the holder taking up the slip-on brush in a curve-like opening of a free disc is changed in its dimension, thus producing a variation of the angular deflection of the rotating shaft.
