Patent DE-3019277-A1 (DE)
Title: Gold alloy contg. no copper, and used for dental applications - contain gold, silver, palladium, zinc and germanium, providing optimum combination of properties and cost
Inventor: EURICH KLAUS
IPC: A61K6/04
Filed: 1980-05-21
Abstract: The alloy contains by wt. 60-80% gold, 3-5% zinc, 1-3% germanium and unspecified amts. of silver and palladium; but no copper is present. When the alloy possesses the max. permissible amt. of zinc, vis. 5% the amt.of Ge present is 2%. The alloy is pref. used as either a casting or a forging. Copper causes the discoloration of dental prosthesis, so alloys contg. no Cu are required. A suitable alloy is described in 2509476 and contains 2-5% Zn to increase its hardness; but a Zn content of over ca. 3% causes a loss of ductility. It has now been discovered that an addn. of Ge improves the ductility of relatively hard alloys contg. up to 5% Zn. The results in an optimum combination of hardness, ductility and cost.

Inventor: IMAI TETSUICHI
IPC: H01F7/00
Filed: 1980-07-18
Abstract: The actuator is typically applied to the operating of a valve where conditions do not favour the use of an electromagnetic design. The permanent magnet, normally in the form of a ring (6), is movable axially over the outside of a cylindrical sleeve (1) which is made of non-magnetic material. Inside the sleeve is an armature (3) attached to a plunger (5). The armature is magnetic, the plunger may be non-magnetic. The plunger typically drives the moving part (7) of a valve. At the closed end of the sleeve is a fixed insert (2) of magnetic material joined by a spring (4) to the armature. The spring acts to hold the valve closed. Opening occurs when the permanent magnet (6) is moved, by mechanical means, to a position where its flux links with the armature and moves the plunger against the action of the spring.

Title: Crucibleless zone melting - using heating circuit frequency tuned from half to twice the HF generator frequency
Inventor: KELLER WOLFGANG DR RER NAT
IPC: C30B13/20
Filed: 1980-09-18
Abstract: Crucibleless, zone melting system for a vertical semiconductor rod, esp. a silicon rod, uses an induction heating coil to produce a melting zone which is moved along the rod centre line. The heating circuit is supplied with a.c. from a multi-stage high-frequency generator. It consists of the induction heating coil and a capacitor in parallel to the coil, tuned to a frequency which is less than 2 times (1-1.5) greater or smaller than the frequency of the HF generator. This simplifies the output control and the filtration. It permits large fusion inputs to the rod under greatly different load conditions. The compensation of the watt-less current results in a better efficiency.
Patent DE-3046388-A1 (DE)
Title: Edge filter e.g. for internal combustion engine - having rotary scraper to remove dirt, enclosed by spring-loaded collector
Inventor: HAMM HANS-PETER ING GRAD
IPC: B01D29/19
Filed: 1980-12-09
Abstract: Soiled liq. is fed into the wall of an edge filter contg. a hollow cylindrical filter body made of laminae or wire coils and divided by a stellate core into compartments for filtrate. The core is rotatable by an external ratchet. Movable round the filter body is a scraper blade for removing deposited dirt. This scraper is surrounded by a U-shaped collector channel with spring-loaded sides which normally allows soiled liq. to pass through a gap, but closes this gap when one side of the U shapes into the recess(es) of one or more guide rings at the ends of the filter. The liq. flow then removes the accumulated dirt for discharge through a valve-controlled outlet. For filtration e.g. of lubricants in IC engines, wherein soil tends to cling to the scraper, and provides adequate flow to remove this soil. The filter may be in any position e.g. horizontal.

Patent DE-3100006-A1 (DE)
Title: Telescopic supporting element
Inventor: KNAUER DIETER
IPC: B25J9/00
Filed: 1981-01-02
Abstract: The invention relates to a "telescopic supporting element" which, in the extended state, is stiff in one mode direction and consists of individual elements which are connected to one another in a jointed manner. In this case, the rotational mobility of the two respectively directly adjacent stops of two pairs of stops is limited in both the clockwise direction and the anti-clockwise direction by additional limiting parts. These limiting parts are in this case preferably constructed as transverse connecting elements of the two external attachment elements (see Fig. 1). In this way, a telescopic supporting element can be used primarily even where retraction and extension of the supporting element must take place in very short time periods, as is the case, for example, with manipulators. <IMAGE>
Patent DE-3100057-A1 (DE)
Title: Temperature-compensated electrical moisture transducer
Inventor: MUELLER JOHANNES
IPC: G01N27/22
Filed: 1981-01-02
Abstract: The field of application of the electrical moisture transducer having temperature compensation is that of analytical measurements. In the electrical moisture transducer according to the invention, the effect of temperature of the object to be measured on the measured moisture value is compensated for faultlessly, without having to employ a temperature-measuring element with its known drawbacks. This is achieved by inserting one or more dielectric moisture-measuring elements in the circuitry of a phase-shift oscillator. As a result, a moisture-dependent, frequency-analog electrical signal is produced in the oscillator. When the temperature of the object to be measured changes, the latter's reactance and resistance change in the same direction. This identical-direction effect of the temperature on these two types of resistance is converted in the phase-shift oscillator into an effect in the opposite direction on the oscillator frequency.

Filed: 1981-02-18
Abstract: A container arrangement, for example a heat exchanger with a storage function, has an outside container and an inside container arranged therein. In order to provide a simple construction, the two containers (1, 2) have longitudinal edges (14, 15; 16, 17) bent outwards from their container walls (3, 8), and the longitudinal edges (16, 17) of the inside container (2) lie between those of the outside container (1). The longitudinal edges (14, 15; 16, 17) are connected tightly to one another. Additionally, a method for producing such a container arrangement is proposed. <IMAGE>
Patent DE-3109482-A1 (DE)
Inventor: BRAJDER ANTONIO DIPL ING
IPC: H02H7/08
Filed: 1981-03-12
Abstract: A short-circuit protection device for a DC control element has at least one transistor which is addressed by timing pulses obtained by comparison of a triangular voltage with a control voltage. Each such transistor is provided with a separate overcurrent protection device which, after a short circuit, blocks the associated transistor until the beginning of a new switching-on pulse. The control voltage assumes values which are above the maximum value of the triangular voltage. In the event of a short circuit, the transistor concerned is switched off very fast, but is switched on again by the next succeeding switching-on pulse and a determination is made as to whether the short circuit is still present. If the control voltage rises to values which are above the maximum value of the triangular voltage because the actual value of the load current deviates heavily from the reference value due to the disconnection of the transistors, the transistors remain switched off until the DC control element is restored to operation by external intervention.
Patent DE-3110431-A1 (DE)
Title: Wood-working machine, in particular for sanding profiled surfaces of strip-shaped and/or panel-shaped workpieces
Inventor: FRIED JOHANNES
IPC: B24B35/00
Filed: 1981-03-18
Abstract: The sanding assembly, having sanding blocks which oscillate to and fro in the advancement direction of the bars or strips to be sanded, is mounted in a floating manner transversely to the advancement direction, with the result that it can follow parts of the workpiece which deviate from a completely straight line (that is to say curved workpieces). This also gives rise to the possibility of designing the wood-working machine as an edge sander, in which sanding can also be carried out by a side surface of the sanding block. <IMAGE>

Title: Wick lamp
Inventor: CAMPHAUSEN HANS
IPC: F21S13/00
Filed: 1981-03-13
Abstract: A description is given of a wick lamp for liquid fuel and for the use, in particular, of thin wicks. Since because it burns down the wick has to be drawn up in specific time intervals it is provided for the purpose of achieving the object of producing a wick lamp of simple and inexpensive design in which the wick can be drawn up from the fuel container without any problem that the wick tube has a sleeve which can be displaced in the longitudinal direction of the tube and has an outwardly projecting handle. The outwardly projecting handle can be used to displace the sleeve downwards, that is to say in the direction of the combustion chamber, for the purpose of drawing the wick up. This action uncovers a sufficiently long wick end which can be gripped without difficulty by hand, by means of pincers/tweezers etc. and drawn further upwards. The sleeve is subsequently pushed upwards again using the handle.

Title: Process for producing a socket or socket interior lining with elastic sealing ring for pipe plug-in connections
Inventor: WOLF FRANZ-JOSEF
IPC: B28B21/56
Filed: 1981-05-12
Abstract: The invention relates to a process for producing a socket or socket interior lining with elastic sealing ring for pipe plug-in connections, in which process the socket or the socket interior lining is formed around a forming core provided with a sealing ring. The process is characterised by the exclusive use of a single, one-part forming core onto which the elastomeric sealing ring is braced, with significant radial expansion, in the configuration in which it also carries out its sealing effect when in operational use on the outer wall of the spigot end. After hardening of the material of the socket or socket interior lining, formed around the forming core provided with the sealing ring, the forming core is drawn out of the socket, and the sealing ring, retained by the resulting socket and stripped away from the forming core, then resumes, owing to the elastomeric restoring forces effective in it, at least to a large extent the configuration which it also exhibits when it is relieved of pressure. The sealing ring, relieved of pressure, is retained in the annular groove, formed by the ring itself in the socket material, either by obstructing the recovery movement owing to the insufficiently large radius of the groove formed, that is to say by radial ring compression, or by annular anchoring members which are integrally formed on the sealing ring such that they project radially outwards. The process is preferably used for producing bell-type sockets, provided with integrated sealing, of concrete pipes and also for producing plastic sealing linings in prefabricated bell-type sockets consisting of mineral materials, in particular fired clay.
