Title: Centrifugal caster, in particular for dental uses
Inventor: KREBSER WERNER ING
IPC: B22D13/06
Filed: 1982-09-29
Abstract: The invention relates to a centrifugal caster, in particular for dental uses, and to an automatic centrifugal casting machine, equipped therewith, which has a device for compensating the unbalance in the case of different sizes of casting muffle, the device comprising a centrifuging arm secured at the end of a drive shaft, an essentially vertically arranged muffle holder at one end of the centrifuging arm, a balance weight arranged displaceably along the other end of the centrifuging arm, and a melting crucible. The centrifugal caster according to the invention has the advantage that unbalances during the centrifuging operation can be largely avoided and, furthermore, the automatic centrifugal casting machine has the advantage that access to the rotating centrifuging arm is prevented. The centrifugal caster is distinguished by the fact that the muffle holder and the balance weight are in mutual drive connection in such a way that, as the muffle holder is set to the size of the attached casting muffle, the balance weight is displaced synchronously to the corresponding position on the centrifuging arm to balance the weight of the muffle.

Title: Arrangement of a return path in a magnet system
Inventor: GRUTZECK ACHIM
IPC: H01F3/10
Filed: 1982-12-07
Abstract: The purpose of the present arrangement is to reduce the strong capability which external magnetic shunt circuits have to influence open magnet systems, and to achieve an increased magnetic flux in the air gap, and at the same time to produce a space-saving shape, matched to normal housing shapes for these applications, which results in a corresponding saving in space. This arrangement can advantageously be used in conjunction with known semiconductors which are sensitive to magnetic flux, such as magnetoresistors, as potentiometers without contacts.

Title: Process for producing In Sn oxide layers
Inventor: LEIDICH DIETER DIPL ING
IPC: H01L31/0216
Filed: 1983-03-19
Abstract: The invention relates to a process for producing In Sn oxide layers by cathode sputtering alloys of the metals indium and tin. Such layers are optically transparent and metallically conducting, and they are used, for example, as antireflection layers in solar cells and on heatable window panes. While retaining transparency in the visible range, the electrical conductivity hitherto achieved in such In Sn oxide layers is increased, according to the invention, by choosing, as the substrate temperature at which deposition is carried out, the maximum still permissible temperature of the substrate material in question and matching this maximum possible substrate temperature to the partial pressure of oxygen.

Title: Metal-coating process and device, in particular for copper-plating cylindrical bodies
Inventor: ETTL ERNST DR
IPC: C25D17/00
Filed: 1983-07-13
Abstract: To simplify the construction of copper-plating plants for impression cylinders used, in particular, in gravure printing, the invention provides for the use of an accelerating anode (4) between an anodically connected copper material (5) and the surface of the rotationally driven cylinder (1) to be copper-plated. The accelerating anode (4) is preferably of grid-type and is composed of an insoluble metal, in particular an alloy containing high proportions of titanium, niobium and/or tantalum. With the cylinder (1) rotating, a desired turbulent flow is achieved as a result of the grid structure of the accelerating anode (4), as a result of which the current density can additionally be increased to values of 100 A/dm<2> and over. Copper-plating times are achieved which can otherwise only be achieved with full immersion. <IMAGE>

Title: Plastic wall bottle
Inventor: HAUSHAHN ERWIN
IPC: A47K5/03
Filed: 1983-10-28
Abstract: For easier handling and disposal of a plastic bottle after use, in the sphere of the application, the plastic wall bottle is provided with a suction holder, which can be separated from the bottle, and can thus be pressed onto any desired point of a wall with a smooth surface, i.e. can be attached without auxiliaries, such as hooks, nails, screws or the like. If, in the plastic wall bottle in the attachment state described, the closure and dispensing device is arranged at the bottom of the bottle, there is the possibility of removing the contents from the bottle without the plastic wall bottle needing to be taken from the wall. Removal of the plastic wall bottle from the wall with the intention of returning the bottle back to this place after use takes place without great effort, in that the plastic wall bottle is pulled upwards from the suction holder. If it is to assume the previous place again, the plastic wall bottle is again pushed onto the suction holder which remained on the wall. The place on the wall or other smooth surface, at which the bottle has been pressed on, is its storage place when the plastic wall bottle is not in use. In this manner, space for other things in cabinets or on shelves and tidiness is provided. In use, the plastic wall bottle saves time and effort.

Title: Apparatus for the spinning of spinnable fibres round a spun-fibre string
Inventor: SCHIMINSKI HERBERT
IPC: D01H1/11
Filed: 1983-11-17
Abstract: An apparatus for the spinning of spinnable fibres round a spun-fibre string consists of a friction false twister and of a preceding ballooning device which positively guides the spun-fibre string. The ballooning device preferably consists of rotary-driven discs having parallel drive shafts which have especially a non-round circumference. Their axes lie at the corners of an equilateral triangle, and the discs, which touch and drive the spun-fibre string with part of their circumference, overlap one another. By phase shift of the regions of the disc circumference, for a uniform direction of rotation the rotary direction of the balloon can be adjusted and even reversed. Various twist components act on the spun-fibre string delivered by a drawing unit. The main portion is generated by friction false twister. In addition to this, a false-twist portion arises from the ballooning movement as a result of the mechanical positive guidance and a portion arises from the action of the discs on the circumference of the spun-fibre string. The apparatus is preferably operated in such a way that the twist running back in the spun-fibre string from the clamping point of the friction false twister is directed opposite the remaining twist components. This, as a result of the centrifugal forces, causes individual fibre ends in the region of the yarn balloon to come out of the spun-fibre string and project laterally. During passage through the clamping point of the ... Original abstract incomplete.

Title: Vehicle wheel with inner emergency running wheel
Inventor: ORDU ARMIN DIPL ING
IPC: B60C17/04
Filed: 1984-02-18
Abstract: The invention relates to a vehicle wheel with inner emergency running wheel which is composed of a plurality of, preferably four, segments. The segments having an essentially double T-shaped cross-section are each clamped into the groove of the full-drop centre by means of two clamping screws. In order to improve the mounting properties of the emergency running wheel, a free space which is kept completely free of installations is provided between the foot of the segment and the tyre beads, which space permits movability and easy alignment of the segment pieces in the circumferential direction. Axial grooves on the sole of the segment foot at a distance corresponding approximately to the diameter of the clamping screws facilitate the alignment, in terms of circumference, of the segments during mounting. Attachment of the segments with two screws in each case, all the screws being uniformly distributed over the circumference when the emergency running wheel is completely mounted, reduces the displacement paths of the segments in the circumferential direction in order to be able to screw them tight. An undercut hollow at the threaded holes permits a round cord ring to be held securely in a mechanical fashion for the sake of sealing the screws and permits the said ring to be inserted conveniently and without causing damage into the sealing point before the segments are mounted.
