Title: High temp. insulation for control cables - involves wrapping aramid paper longitudinally around cable core
Inventor: STERNER RICHARD
IPC: H01B7/18
Filed: 1979-11-29
Abstract: A paper made of an aramid material (4) is applied to the conductor core (2) so that the edges (5,6) of the paper tape form an overlapped joint (7) running parallel with the core axis. The aramid paper lends itself readily to this form of application, and thus eliminates the need for a revolving taping head. The overlapped strip is held in position by threads of the same material applied as a braid (8). The braiding may then be impregnated and covered by a sheath (9). The cable insulation is typically suited for applications where the temp. does not exceed, but is in the neighbourhood, of 180 deg.C. It has high resistance to crushing and abrasion. Useful for insulating ovens or boilers etc. The wrapping process is simplified.

Title: Worn roller compensating system - has cutting tool on lathe bed beside rollers with separate motor turning rollers during machining
Inventor: WYSS KURT
IPC: B23B5/00
Filed: 1980-01-25
Abstract: A movable device (19) truing the rollers (2,3) by means of a cutting tool is located near the rollers. Screws are welded to the spindles to allow the bed of the device to be aligned with precision with the axes of the rollers. The screws pass through plates fixed to the bed. The bed can therefore be set with precision w.r.t the axes of the rollers. A separate motor (31) is connected via a drive belt (32) to an extra wheel (33) fixed to the output shaft of the main motor (11). The separate motor is used to turn the rollers during machining. The main motor used during normal operation is not excited but is rotated as well whilst the roller is being cut.. The device (19) allows rollers to be adjusted, quickly, simply and rationally. The rolling mill is therefore only out of action for a short while for the adjustment.

Title: Optical volume control - has plate with increasing opacity moving between light source and receiver
Inventor: WEISS WERNER ING GRAD
IPC: H03G1/00
Filed: 1980-05-28
Abstract: Normal optical volume controls employ a control element consisting of a thin metal plate with a wedge-shaped cut-out moved between a light source and receiver. This requires great precision but is avoided by using a transparent plate with increasing opacity in the direction of movement. Alternatively, a plate with increasing reflective power may be used. In this case light source and receiver are placed on the same side of the moving reflecting surface. The transparent plate (8) is moved via a rack (9) and pinion (9) between a photodiode (11) and phototransistor (12). Instead of the flat plate an evenly toned wedge-shaped prism may be used.

Title: Gas cooled high temp. reactor having structural side shield - built of courses of segments, esp. of cast iron
Inventor: ELTER CLAUS DR
IPC: G21C1/07
Filed: 1980-07-19
Abstract: Gas-cooled, high-temp. reactor has a core composed of spherical fuel elements (pebble bed reactor), and absorber rods which can be introduced directly into the core. The core is surrounded by top, bottom and cylindrical side reflectors built up of graphite blocks. The side reflector is radially supported across an annular gap from the thermal side shield which surrounds it. The shield is a self-supporting cylinder, standing on the bottom plate of the reactor and composed of a series of courses, each of which is made up of segments, which are firmly connected together with one another at their butt joints. Pref., the butt joints between segments are located in zones of the side shield where little or no bending moment occurs as the result of symmetrically distributed radial loads. The side reflector is a structurally stable and firm unit, capable of accepting the horizontal radial forces from the reactor even where a local failure of the side shield occurs. The resultant forces are reliably transmitted down through the bottom plate to the pressure vessel without thermal stresses occurring.

Title: Apparatus for the embossing of sheet-metal parts
Inventor: LANGE FRITZ
IPC: B44B5/00
Filed: 1981-02-07
Abstract: For the embossing of number-plates, embossing blocks, each consisting of a pair of plates held parallel to one another, are used. The plates can be pressed against one another and, at the same time, are guided in parallel by guide pins. Since the plates of the embossing blocks can be guided on one side only, a desired exact parallel guidance cannot be achieved. Tilting and pronounced wear in the region of the guide pins easily occur. To prevent this, the embossing positives consist of a magnetisable material. They can be inserted, together with the dies, into one of two plates which are connected to one another in a hinge-like manner, can be pressed against one another, whilst maintaining a parallel position, and receive the sheet-metal part to be embossed. The upper plate is designed with its inward-pointing face made of magnetisable material.

Title: Pipe of fibre-reinforced metal
Inventor: LEIS HANS DIPL PHYS DR
IPC: C22C47/06
Filed: 1981-12-24
Abstract: To produce a high-strength light-weight pipe, a prefabricated strip of fibre-reinforced metal is wound in several plies around a mandrel provided with a separating layer and consisting of a material having a high thermal expansion. During winding, plies are applied in the longitudinal direction of the fibre and transversely thereto. The plies are wound on up to a thickness of about 1 mm more than the thickness of the pipe to be fabricated, radial plies being used at the end. Subsequently, plies of a fibre material, which has almost no thermal and elastic expansion, are wound on radially in approximately half the thickness of the pipe wall. After the winding process, the entire wound package is introduced into a vacuum oven and, after evacuation and heating, exposed to a temperature appropriate to the materials used. Due to the high thermal expansion of the winding mandrel and due to the low thermal expansion of the fibre covering, a compaction and bonding by fusion or diffusion of the wound plies of the fibre-reinforced material takes place. After cooling and flooding of the vacuum oven, the wound package is taken out and, after removal of the winding mandrel and of the fibre covering, the finished pipe is available ready for use.
