Title: Brittle material cutting mechanism - has grooved pulleys on axes inclined to each other guiding moving cutting wire
Inventor: MECH HAROLD WALTER
IPC: B26D1/48
Filed: 1973-12-03
Abstract: The mechanism is particularly for cutting materials for semiconductors, crystals etc. using a wire continuously delivered by a feed mechanism and removed after use.

Title: Continuous billet casting method - billets are reheated for further shaping by DC flow
Inventor: BREUER ERICH
IPC: C21D1/40
Filed: 1974-02-09
Abstract: In the continuous casting process every second billet is turned around its longitudinal axis before reaching the tempering furnace. Then the billets are left in the tempering furnace next to each other, until they have the same temperature along their whole length. They are then consecutively applied to a conduction heating device. The billets in the tempering furnace are heated to a temperature below that reached in the conduction heating device. The turning device and furnace are placed in the billet path from the cutting station behind the casting station, and the conduction heating device.

Title: Capacitance variation diodes prodn. - is based on mask application and diffusion of small area zones in opposite conductivity epitaxial layer
Inventor: WILKE HANS
IPC: H01L29/93
Filed: 1974-02-27
Abstract: Each diode forms a pn-junction on a semiconductor substrate with an epitactic deposited layer, both of the same conductivity. In the epitactic layer is formed a small number of small zones of a second conductivity by diffusion to a low depth, forming the pn-junctions for test diodes. Their capacity is measured and related to the desired diode capacitance, using mask with different aperture cross sections. Finally the mask with optimum apertures is selected for adjusting the desired diode capacitance. The final zone of the second conductivity is then diffused using this mask. Preferably the capacitance relation are graphically plotted for precise selection of the mask. The test diodes pn-junctions surface may be smaller than the surface of the capacitance diodes junctions.

Title: Crimping method for electric terminal attachment - employs small deformable aluminium tube to link terminal lugs with twisted wire
Inventor: EDWARDS SEN JOSEPH R
IPC: H01R4/62
Filed: 1974-04-01
Abstract: The crimping system for attaching a terminal (12) to an electrical wire or cable (6) uses an aluminium tubular member (10) with the wire end (8) crimped by a deforming tool which plastically deforms the tube to press it into firm engagement with the wire.

Title: Fastening for sheet metal edges - uses undercut in the profiled section and synthetic cement
Inventor: GMOEHLING WALTER
IPC: F16B13/00
Filed: 1974-04-06
Abstract: The profiled section has an undercut in the area, where the metal sheet, angled section, etc. is to be fastened. The metal sheet contains perforations, or similar deformations, at the fastening point. A synthetic cement is applied at the joint, to effect a fastening.

Title: Optimisation of adsorption process for sepn. of mixts. - by varying inlet concn. according to adsorption isotherm
Inventor: SILVIU TILENSCHI PROF DR
IPC: B01D15/00
Filed: 1974-05-15
Abstract: The technology of sepg. liq. or gaseous mixts. by adsorption is improved by not only selecting the required quantity of adsorbent but also by selecting or changing the initial concn. of the mixt. according to its actual adsorption isotherm, so that the resultant loading of thead-adsorbent (with adsorbed components) is as high as possible. For example, the initial concn. of a liq. whose absorption isotherm exhibits maxima is reduced, using the same solvent, to a value lying below the close to the appropriate maximum before the liq. is treated with adsorbent. This reduction can be achieved also using a small quantity of the adsorbent. In processes employing multistage counter flow adsorption, the quantity of adsorbent used in each stage is determined from the appropriate adsorption isotherm so that each stage uses an individually suitable quantity. The technique is applicable to all adsorption processes for sepn. of liq. and gaseous mixts. (1) the size and cost of the plant and the quantity of adsorbent required are reduced. (2) Adsorbent losses due to friction and attention are reduced.

Title: Dumping skip lifting tackle - has locking mechanism automatically securing to frame during tipping operation
Inventor: WUERTELE RAINER
IPC: B66C1/16
Filed: 1974-09-27
Abstract: The skip has a protruding portion, typically a bent-over edge, by means of which it is supported in a lifting and tipping frame.
