Title: Induction heating of metal objects - where inductor contains core cooled by liq. gas so heating power can be increased, esp. in mfg. seam welded pipe or tube
Inventor: SILLAT DIETER
IPC: B23K13/00
Filed: 1978-10-04
Abstract: The process employs a heating inductor, plus a magnet core which is cooled by a cold liq. which is a gas at normal temps. The liq. is heated in cooling the core and evaporates to form a gas which is removed from the vicinity of the core. Alternatively, the liq. gas may be evaporated to form a cold gas which is then used to cool the core. The liq. is pref. N2, a noble gas, or CO2. The pref. appts. includes a protective sheath surrounding the magnet core to form an annular gap into which the cold fluid is fed so ice forms on the outside surface of the sheath. The process is pref. used for induction-welding, -brazing, and -soldering. Due to the efficient cooling of the core, the output of an induction welding plant employed in the mfr. of seam welded steel pipe or tube can be increased by 20%.

Title: Solid state element construction process - using EM, electron or ion beams directed onto selected regions of layer to change their crystalline state
Inventor: SCHAUMBURG HANNO DR
IPC: H01L21/268
Filed: 1978-11-08
Abstract: A semiconductor construction element is produced with little or no masking or heat treatment. The solid-state body has several bounded regions of various crystalline states. Selected regions of a solid-state material layer have their crystalline state changed by energy conveyed by a wave or particle type beam. Electro-magnetic, electron or ion rays can be used to transmit this transforming energy. The beam can be controlled so that it is deflected exclusively onto the regions to be changed. The solid-state material layer can be mounted on a substrate. Several solid-state material layers can be mounted on top of each other, each having selected regions changed after mounting. The layer can consist of amorphous material changed to polycrystalline and/monocrystalline material.

Title: Contact free position sensing of semiconductor elements - using a raster scan the signal from which is processed
Inventor: DOEMENS GUENTER DR
IPC: G06T7/70
Filed: 1979-02-28
Abstract: Position of a semiconductor element is determined from its cut edge, or a system edge on its surface, by scanning the surface in a raster fashion in zones which extend partly over the element and partly over its surround, the raster lines being parallel the element edge. The instantaneous intensities of the brightness values are integrated in each line or in each of a number of line sections the resultant values being stored and differences derived between the results of consecutive line scans, that polarity which corresponds to the investigated edge is selected for further analysis, and the selected results are weighted with respective factors corresp. to the local roughness of the particular position in the image, so that differences in a rough zone are weakened and those in a smooth zone emphasised. An additional electronic width evaluation is performed to emphasise sharp edged lines relative to wide regions so that, by row counting, a signal for correcting the position of the chip is formed, to be used to automatically correct the element position. Used in positioning integrated circuit elements in automatic wiring equipment, or automatic alloying or adhesive fixing equipment. Method provides a position sensing system which is independent of type, contrast, or surface conditions of the semiconductor elements and which can be implemented with low equipment outlay.

Patent DE-2939154-A1 (DE)
Inventor: MCLUSKIE ALBERT
IPC: D01G1/04
Filed: 1979-09-27
Abstract: A machine for cutting a travelling tow of synthetic plastic filaments to produce staple fibers has a blade carrier from which cutting blades project and have their free ends secured to a concentric surrounding ring. The facing annular surfaces of ring and carrier are shaped to resemble portions of a hollow and of a solid sphere, respectively, and together define an annular cutting channel. A tow pressing ring is arranged skew to the axis of this channel, so that it enters into the channel at one side but is spaced from and defines with the inlet to the channel a gap at the opposite side. One or the other of the carrier and ring is positively rotated. When tow is fed through the gap into the channel it forms on the carrier one or more convolutions which are progressively pressed deeper into the channel by the pressing ring until they reach and are cut by the cutting blades.
