Patent DE-3238641-A1 (DE)
Title: Refuge receptacle
Inventor: WESTERFELD MANFRED
IPC: B30B9/30
Filed: 1982-10-19
Abstract: In refuge receptacles having their own filling press, particular design difficulties arise when the filling press is to be arranged at the tail side, i.e. in the region of the tail flap (emptying flap). However, this arrangement is advantageous for charging a receptacle from ramps or conveyors since the receptacle can be set down directly by a transport vehicle with the filling press towards the charging site. Difficulties such as inadequate pressing action and unfavourable (tail-heavy) weight distribution which conventionally occur in such presses are eliminated by dividing up the region at the rear of the press with a predominantly horizontal partition wall over which the filling press is arranged and under which, in consequence of the elasticity of the refuge, a useable storage space is provided.

Title: Method for fixing windings by means of pretensioned slot closure parts, and a device for carrying out the method
Inventor: PIUR ARMIN
IPC: H02K3/48
Filed: 1982-11-09
Abstract: In the case of fixing, which is known per se, of windings (6) which consist of individual coils and are laid in slots (5), the slot closure parts, which consist of a slot closure wedge (43) or of an intermediate layer, a spring element (11) and a spring support (21), are connected to one another to form a stack, and are pretensioned, before installation in the machine by means of a temperature-dependent fixing according to the invention, for example by means of plastic screws with a loss of combined tension and shear strength between 50 and 80 DEG C, or by means of adhesive coatings (7) with a loss of adhesion capability between 50 and 80 DEG C, in order subsequently to be inserted or pushed into the slots of the machine and to be attached by means of slot closure wedges. The apparatus, preferably an electrical machine, is heated to a predetermined temperature at which the additional fixing looses its strength, and the full spring force of the spring elements (11) thus becomes free and the slots (5) are closed under stress. <IMAGE>

Title: Process for producing semiconductor devices
Inventor: SCHWARZL SIEGFRIED DR
IPC: H01L21/311
Filed: 1983-02-25
Abstract: The invention relates to a process for the defined etching of vias by means of plasma etching through an SiO2 layer produced on a semiconductor substrate which accommodates the doping structure of the semiconductor device to be produced, in which process underetching of the photoresist etching mask responsible for dimensioning the vias is avoided. For this purpose, according to the invention, the reaction gas used to produce the etching plasma takes the form of a mixture of trifluoroethylene and hexafluoroethylene. In addition, the gas flow in the treatment vessel used to carry out the etching operation and the other conditions are adjusted in such a way that the reaction gas mixture converted into a plasma extends parallel to the surface of the semiconductor substrate wafer and, consequently, parallel to the surface of the two electrode plates producing the plasma.

Title: Tool for manufacturing ribbed sheet-metal casings
Inventor: LINHARDT PETER DIPL ING
IPC: B21D13/02
Filed: 1983-03-24
Abstract: On a tool for manufacturing sheet-metal ribbed casings by progressive bending and pressing together of the walls of individual ribs in two forming and calibrating jaw pairs displaceable in opposite directions on a plate, the object to be achieved is to provide such a tool by means of which the consolidation of the foot of the formed ribs of the ribbed part can be performed directly in the forming tool in a simple manner and the life of the welding electrodes can be increased. The invention achieves this object by the fact that the first welding electrode is accommodated in the lower forming jaw and the second welding electrode is accommodated in the lower calibrating jaw. By virtue of the fact that the welding electrodes are accommodated in the lower calibrating jaw and the lower forming jaw, the supply of welding current is fed into the area of the resistance projection welding and the welding of the foot of the formed ribs of the ribbed part is thus ensured.

Patent DE-3314751-A1 (DE)
Inventor: KLEIN KLAUS WALTER
IPC: F42B14/06
Filed: 1983-04-23
Abstract: An improved nose construction for a subcaliber inertial projectile which is fired with the aid of a sabot. A hood or body is mounted on the nose portion of the projectile. The hood is made of synthetic material and includes longitudinally extending fracture zones and is of substantially cylindrical shape. The frontal portion of the hood is recessed and forms an air flow receiving surface. In lieu of a hood a body, made of a thermoplastic material or the like, may be mounted on the nose portion. This body is adapted to disintegrate as result of air friction. The presence of the hood or body on the nose portion of the projectile, as it exits from a non-illustrated gun barrel, avoids or at least reduces unfavorable air-streaming forces which destabilize the flight characteristics of the projectile and thereby favors a uniform separation of the sabot segments from the projectile. Such uniform separation reduces or completely eliminates undesirable oscillations during flight of the projectile. After the hood or body have disintegrated the projectile acquires a more favorable cw value (drag coefficient during flight.

Title: Process for the production of a divided chain guard which is composed of plastic material and is intended for bicycles or the like, and chain guard produced by the process
Inventor: SCHOOTSTRA RENZE
IPC: B62J13/04
Filed: 1983-06-08
Abstract: Divided chain guards produced from stiff plastic material are injection-moulded, for which a relatively expensive mould is required. A plurality of moulds are required for various bicycle sizes. The invention makes it possible to produce chain guards of this type cheaply without using expensive moulds, to be precise by virtue of the fact that starting from relatively thin plastic plates the chain guard halves or parts of these halves are produced by vacuum deformation.
Patent DE-3321240-A1 (DE)
Title: Hydraulic unit with at least two pumps
Inventor: ALTMANN UWE ING GRAD
IPC: F15B11/17
Filed: 1983-06-11
Abstract: A hydraulic unit (10) with two fixed-displacement pumps (11, 12) driven by an internal combustion engine (14) is proposed which delivers into a common consumer circuit (13). The first pump (11) is connected to the consumer (13) via a main line (15) kept free of restrictor elements, while the second pump (12) delivers to the consumer (13) or can be relieved to the tank (18) via a restriction point (26) with allocated cut-off valve (21). From the accumulated flow conducted to the consumer (13), a secondary-flow line (19) branches off to the tank (18) via an adjustable flow-control device (28), as a result of which the size of the accumulated flow to the consumer (13) can be adjusted. With inexpensive fixed-displacement pumps (11, 12), a consumer (13) can thus be controlled in an energy-saving manner at greatly fluctuating drive speeds, as is desired, for example, in thermostatically controlled fan drives in vehicles. <IMAGE>

The disclosed process permits the production of negative copies with the aid of a material which yields positive copies when it is processed in a conventional manner.
Patent DE-3333099-A1 (DE)
Title: Feeding device for the continuous conveying of a pile of sheets
Inventor: GRUEGER CHRISTIAN DR ING
IPC: B65H1/18
Filed: 1983-09-14
Abstract: The invention relates to a feeding device for the continuous conveying of a pile of sheets, preferably for use in flat pile sheet feeders. The aim of the invention is to ensure continuous conveying of piles in flat pile sheet feeders, with elimination of the disadvantages occurring in known intermittently operating feed devices. To this end, the accelerations or delays during the conveying process must be minimised with simultaneous guaranteeing a constant feed of sheets into the separation region. According to the invention, this is achieved by carrying out signal processing preferably in time with the suction device and providing adjustable resistances which can be switched on or off via a shift register as an adjusting element for regulation of the number of rotations of the pile-conveying motor. The advantage is that the feed is not corrected abruptly with harsh acceleration of the motor, but that this process is damped as a result of the dependence on the cycle. <IMAGE>

The deaeration container 7 has a pressure switch 13, a level switch 14 and a deaeration valve 16. The control of the deaeration valve takes place through an evaluation unit 20 which is connected via a duct 19 to the deaeration valve and via ducts 17 and 18 to the pressure switch 13 and to the level switch 14.   <IMAGE>
Patent DE-3348028-A1 (DE)
Title: Terminal block for printed circuit card
Filed: 1983-12-20
Abstract: Inside the insulation housing (2) of the terminal block is a leaf spring contact (6). The spring is bent round upon itself by more than 360 deg., typically 540 deg., to give an outer limb (7) which acts as a contact face, and an inner limb (8) which presses an inserted conductor (5) against the contact face (7). The conductor enters through a hole (4) in the casing and a hole (9) in the leaf spring. The shape of the spring and position of the entry hole (9) ensure that, even with quite considerable force, the conductor cannot be pulled out. The one piece housing (2) is hinged (21) and clipped together such that it too will not open due to tensile force applied to the conductor.

Title: Apparatus for Kerr effect analyses
Inventor: KUSS EDUARD PROF DR
IPC: G01N21/23
Filed: 1984-02-28
Abstract: According to the geometrical shape of a molecule, the polarisability - i.e. the electric dipole moment induced by a field intensity of 1 - differs in the three main axis directions of a molecule. In the absence of a permanent dipole moment, a molecule in a high voltage field is therefore rotated towards the field direction about the axis of the largest polarisability. The consequence of the partial orientation of the molecules is a slight difference in the refractive indices of light components which are linearly polarised in the field direction and vertically thereto. In studying molecular structures, the two refractive indices only differ from the 9th decimal place onwards, and the path differences to be measured of the two components of the light are between one hundredth and one thousandth of a wavelength of the light. In the conventional measuring method, the path difference is cancelled by one of equal size and of opposite direction. In contrast thereto, the measurement method claimed, using a quarter-wave plate, first converts the elliptically polarised light into linearly polarised light but with an appropriately rotated polarisation direction. The rotation of the plane of polarisation is then measured with a Faraday compensator and a Faraday modulator. That current strength in the Faraday compensator, at which the indication in the photometric device passes through zero, is recorded, possibly automatically, a path difference of 1.7 ...

Title: Method for triggering Wiegand pulses
Inventor: KUERS GUENTER DR
IPC: H02N11/00
Filed: 1984-07-26
Abstract: The method for triggering Wiegand pulses by the time-variable action of a permanent magnetic field on Wiegand wires or bistable magnetic elements (BMEs) behaving in a magnetically similar manner, is characterised by the fact that in cases, in which the deviation in the magnetic field strength caused by the time-variable action of the permanent magnetic field on the BME is insufficient for triggering Wiegand pulses, an electrically generated periodically fluctuating additional magnetic field is superimposed on the permanent magnetic field, the alternating frequency of which additional field is high compared with the frequency with which the action of the permanent magnetic field on the BME is varying, and the field strength deviation of which does not drop below the sum of the amounts of the restoring field strength and the saturation field strength of the BME used, the direct field component (the offset) of the electrically generated magnetic field being selected in such a manner that the resultant magnetic field only produces the values of the saturation field strength and the restoring field strength required for the symmetric or asymmetric excitation of the BME in a part-range of the deviation of the permanent magnetic field.

Title: Electric alternating-field, high-frequency therapy device
Inventor: KOZIOL JOHANNES CHR
IPC: A61N1/40
Filed: 1984-10-09
Abstract: The resting potential of cell membranes arises because sodium and potassium ions occur on both sides of the membrane in different concentrations and because in the resting state the membrane is very permeable to potassium ions, whereas it is almost impermeable to sodium ions. If this bioelectrical equilibrium is disturbed by "stress factors" (adrenaline, noradrenaline, serotonin) the differences in tension lead to the following symptoms: MIGRAINE, HEADACHE, AUTONOMIC DISORDERS, SLEEP DISTURBANCES AND BLOOD FLOW DISTURBANCES. However, since the sodium and potassium ions contained in the cell and in the cell interstices are "charge carriers" they can be quickly moved to and fro by electric alternating fields, and, in addition, the cell membrane becomes "conducting". This leads to equilibration of the tension on the disturbed membrane and achieves a considerable alleviation of the above-mentioned, chronic disorders. Objective results can be achieved by clinical tests. Prototype available.
