Patent DE-3100491-A1 (DE)
Title: Erection aid
Inventor: BRUECHLE BERNHARD
IPC: A61F5/41
Filed: 1981-01-09
Abstract: The erection aid serves to improve or restore the capacity to have sexual intercourse of men with inadequate or missing erectility, especially due to organic causes. The problem of previous erection aids of similar design in the form of a penis sleeve of an elastic, sufficiently stiff material open on both sides and with a longitudinal slot on the ventral side, namely the attachment of the sleeve permanently on the penis, is solved, according to the invention, by a special device with which the prepuce is pushed back over the upper edge of the sleeve and is stuck on the outside. This device may comprise a strip of an elastic skin-adhering tape, a separate cuff provided with an adhesive strip, or several lips provided on the penis sleeve. An arched extension on the lower, ventral end of the penis sleeve through which the scrotum is pulled on application additionally ensures, according to the invention, the natural erected position of the penis. <IMAGE>

Title: Toy which can be wheeled up and down on a spring and emits light signals
Inventor: MODEREGGER GEB NEUHOFER
IPC: A63H1/30
Filed: 1981-02-13
Abstract: A toy which can be wheeled up and down on a spring consists of two hollow bodies which are connected at the centre by means of screws or the like and which are at a distance apart which permits the winding-up of the spring, whereby the toy can be rolled up and unrolled. The cavities of the hollow bodies each have a light source which, during play, is actuated and deactuated by a switch and, as a consequence of the transparency of the hollow bodies, radiates light outwards.
Patent DE-3105444-A1 (DE)
Title: Single-phase asynchronous motor for a split-pole-motor pump, especially a heating circulation pump
Inventor: BANDI PAUL DIPL ING
IPC: H02P1/44
Filed: 1981-02-14
Abstract: The electric motor has two windings (1, 2) from which in each case one connection is connected to one of two power supply connecting terminals (7, 8). There is furthermore a power changeover switch (3) which has two operating positions, the motor emitting full power in the first operating position and reduced power in the second operating position. In the first operating position, the full power supply voltage is supplied to the first winding (1) and a series circuit, formed from the second winding (2) and a capacitor (4), is connected in parallel with the first winding. When the power changeover switch is in the second operating position the series circuit formed from the two windings (1, 2) is connected to the power supply voltage, and the said capacitor (4) is connected in parallel with the first winding (1). In order to increase the starting torque of the motor when the power changeover switch is in the second operating position, there is a series circuit which is formed from a further capacitor (5) and a PTC thermistor (6). When the power changeover switch is in the first operating position, the last-mentioned series circuit is ineffective and, in the second operating position, this series circuit is connected in parallel with the first-mentioned capacitor and the first winding. During the starting phase of the motor, both capacitors are effective and, after starting, the resistance of the PTC thermistor increases so greatly that the further capacitor becomes ineffective. <IMAGE>

Title: Service life test device for electromechanical components such as, in particular, motor vehicle switches of all types
Inventor: MOHR EBERHARD
IPC: G01M13/00
Filed: 1981-02-14
Abstract: The invention relates to an automatic tester for electromechanical components such as, in particular, motor vehicle switches of all types, by means of which it is possible for such components to be tested extremely reliably and accurately under practical conditions for their mechanical and electrical service life. Each specimen is assigned an electric stepping motor with a digital controller. It is possible to carry out system inspections. Optimum use is produced by simultaneous operation of a plurality of stepping motors with a corresponding number of specimens in the multidrive with only a single controller. In the event of the overshooting of maximum permissible mechanical or electrical values of a specimen, only the appropriate stepping motor is switched off, and this is noticeable, in particular, in the case of night-time or weekend running of such automatic testers. Because of the few moving parts, there is extremely low, practically negligible wear, and this has a correspondingly advantageous effect on the reliability and on the long service life of such automatic testers. <IMAGE>

Title: Luminaire
IPC: F21V19/00
Filed: 1981-02-26
Abstract: The invention relates to a luminaire having a concave mirror reflector in the sealed interior of which there is arranged a luminous element having a transparent housing, preferably an incandescent lamp. In order that when the incandescent lamp is inserted or exchanged the interior of the concave mirror reflector should remain tightly closed, provision is made of transparent means with the aid of which the interior is isolated from a receiver chamber for the incandescent lamp and thus always remains sealed against the environment. It is also advantageous to use a sealing element to seal against the environment the receiving chamber for the luminous element together with its housing and the bulb of the incandescent lamp. In order that only incandescent lamps having prescribed lighting and electrical values can be inserted into the luminaire, it is advantageous to provide an adaptor having mating faces, the luminaire itself having assigned mating faces. <IMAGE>

Patent DE-3125210-A1 (DE)
Title: Shaft coupling
Inventor: KOTTE JAN JACOB
IPC: F16D11/10
Filed: 1981-06-26
Abstract: The invention proposes a shaft coupling, the two coupling halves of which can be connected to one another in a positive-locking manner under axial preload without a locating twist and consist of two coupling gear wheels (5, 12), each of which have on the mutually opposite side symmetric crown gearing with radially directed teeth. According to the invention, the number of teeth of one coupling gear wheel differs from that of the other by one. One coupling gear wheel (12) can be tilted against spring force by about 8 DEG  relative to the front face of the other gear wheel (5) to be coupled. For this purpose, coupling gear wheel (12) has an outer circumferential surface in the shape of spherical cap via which this gear wheel (12) is supported and axially centred on the inner circumferential surface of a bush (8) which surrounds gear wheel (12) radially is connected to the input shaft (6) in a manner which prevents rotation relative to and allows axial displacement on the latter. Via driver pins (13) which project from the outer circumferential surface of gear wheel (12) and engage in longitudinally displaceable fashion in axial longitudinal slots (30) in the bush (8), coupling gear wheel (12) is connected rotationally to the input shaft (6) via the bush (8). Positive engagement between the two coupling gear wheels (5, 12) is produced by longitudinal displacement of a sleeve (10) surrounding the bush (8), with flank engagement which increases and decreases again in relation to diametrically situated points on the circumference. <IMAGE>

Title: Protection device for an externally excited DC machine
Inventor: KAHLEN HANS DR ING
IPC: H02H7/06
Filed: 1981-10-03
Abstract: The invention relates to a protection device for an externally excited DC machine. The first connection of the field winding (12) of the machine is in this case connected via a first relay contact (18a) to a field current adjuster (4), which is connected on the other side to the negative terminal (2) of a supply voltage source. The second connection of the field winding (12) is connected via a second relay contact (17a) and a transistor (9) to the positive terminal (1) of the supply voltage source. A first capacitor (7) is connected between the positive terminal and the negative terminal as a field energy store in the event of a disturbance. A second capacitor (6), which is connected to the positive terminal (1) and has a resistor (5) connected in parallel, is likewise connected to the second relay contact (17a) via a diode (16). The control connection of the transistor (9) is likewise connected to the positive terminal (1), via a third relay contact (8a). The field winding (12) is connected via in each case one diode (11 and 15) to the supply voltage source. In the event of a disturbance, the third relay contact (8a) opens first, so that the energy of the field winding (12) is partially stored in the capacitor (6). Subsequently, the further relay contacts (17a, 18a) also open, and the remaining energy of the field is stored in the capacitor (7). <IMAGE>

Patent DE-3234814-A1 (DE)
Title: Process for the dephosphorising and desulphurisation of molten steel with simultaneous reduction of the iron and manganese in the slag
Inventor: LIPPE WOLFGANG DIPL ING
IPC: C21C5/28
Filed: 1982-09-20
Abstract: In the basic steel manufacturing processes, it is well known from the refining process that silicon burns off before the carbon and that the dephosphorisation is somewhere in between, that is to say reference is occasionally made in the literature to a dephosphorisation even before the start of the carbon combustion, although it is generally true that the dephosphorisation starts only with the onset of carbon combustion. According to statements in the literature, the combustion of silicon has been investigated only to a small extent - not at all in the opinion of the author. Precisely very small contents of burning silicon and the silicates SiO2 resulting from the combustion are capable of binding considerable quantities of ferrous and manganous oxides as metal lower-oxide silicates, so that, on the one hand, considerable quantities of iron and manganese pass into the slag and, on the other hand, the ferrous oxide necessary for the dephosphorisation is virtually absent and is thus available only after the silicon combustion has ended. The destruction of the silicates, when the silicon combustion subsides, due to compounds of fluorine and/or alkalis, thus suppresses the formation of metal lower-oxide silicates, so that fewer lower metal oxides go into the slag, and, on the other hand, the ferrous oxides necessary for the dephosphorisation are already available in the region of the subsiding silicon combustion. When alkalis are used or added, their outstanding desulphurisation properties are utilised at the same time.

Patent DE-3238805-A1 (DE)
Title: Collection container for solids, in particular used glass
IPC: B65F1/02
Filed: 1982-10-20
Abstract: The collection container 1 is provided with an upper insertion opening 5 and, below the latter, with built-in components for influencing the dropping speed of the inserted solids. The built-in components are constructed as two opposite web-shaped apron sections 13 and 14 which are elastically flexible, enclose between them the cross-section of the insertion opening 5 and hang down from the latter in the longitudinal direction approximately down to the bottom wall 6. The apron section 14 is fitted in the longitudinal direction with spaced-apart elastically flexible tongues 17 and 20 which are connected at one end to the apron section 14 and are inclined with the free end towards the bottom wall 6. The solids inserted in the insertion opening 5 are decelerated gradually whilst dropping through the gap 21 and into the corresponding subsequent gap chambers so that they impact with reduced energy and thus only cause a small amount of noise. <IMAGE>

Title: Process for the solidification of aqueous radioactive waste
Inventor: KADNER MARTIN DIPL CHEM
IPC: G21F9/16
Filed: 1982-10-21
Abstract: To solidify aqueous, nitrate-containing radioactive waste solutions by evaporation with phosphoric acid and conversion of the resulting phosphates into a sparingly-soluble solid, a process is required which permits the preparation of anhydrous final-storage products having good acceptability to known embedding agents and high loading capacity. By mixing the alkali metal phosphate residue (remaining after evaporation) with alkaline earth oxides and/or alkaline earth hydroxides and heating to incandescence at 500 to 950 DEG C, alkali metal/alkaline earth metal phosphates of the rhenanite type are obtained, which are virtually insoluble and which can be embedded in large amounts and with good acceptability in known binders.
