Title: Mica fragmentations process
Inventor: RUZICKA JOSEF
IPC: B03B1/00
Filed: 1969-03-20
Abstract: Ultra delamination of a crystalline, laminated material such as mica into thin plates of flocks, is carried out by (i) pressing a liquid medium through openings in the bottom of a circular converter, perpendicular to the height so that the liquid forms a system of gyrating flows with an orientation approaching the circular path of the conversion zone, (ii) introducing relatively course particles of the solids into this system of gyrating liquid flows, thus disintegrating the particles mainly in planes corresponding with the two main axes of the solid crystal lattice, (iii) bringing the liquid suspension contng the finely divided solid from the bottom area upward to a higher part of the peripheral zone, (iv) recirculating insufficiently divided solid particles from the upward flowing suspension back to the bottom area for further disintegration in the gyrating flows, and (v) removing solids of required fineness from the conversion zone.

Title: Rolling mill fault position and shape detec- - tor
Inventor: BLASER REINHARD DIPL-PHYS DR
IPC: G01B11/04
Filed: 1969-12-12
Abstract: The faults associated with departures from width tolerance esp. for sheet, show up as differences in brightness relative to the surroundings. Two conventional photoelectrically derived partial width signals are summed to give the total measured width and this is compared with a nominal value set on the equipment. The position is derived from the total width, with the two separate partial widths. This stage is not carried out when information on the centre line is available from a supplementary detector on the roller table.

Patent DE-2053165-A1 (DE)
Title: Air fractionation
IPC: F25J5/00
Filed: 1970-10-16
Abstract: The air containing CO2 as an impurity is fed under a first pressure to a hot end (at a first temp) of a heat exchanger for a passage to its cold end at a second temp; alternately through two heat exchanger passages with resultant cooling and CO2 deposition within the cold end region as a solid matter. Rectification is carried out at a third temp. lower than the second one dividing the air stream into a product and a waste stream. The latter is fed back through the heat exchanger, at a pressure lower than the first one from cold to hot end, alternately through the other passage of the exchanger; effecting heat exchange with the air passing through this exchanger, the waste stream entraining the CO2 in the previous cycle. A coolant is fed at a first temp. point into a third passage of the cold end, for flow to the hot end, effecting heat exchange with air and being withdrawn at a second temp. point, higher than the first one. At their temp. point(s) intermediate to the first two temp points the coolant is withdrawn.

Title: Moulding beakers from film - mechanised process for mouldings of any height
Inventor: KLEIN THEODOR
IPC: B29C51/32

Title: Wire rolling mill - with harmetal ring rolls
Inventor: KUERBIS WOLFGANG DIPL ING
IPC: B21B27/02
Filed: 1973-04-12
Abstract: Wire rolling mill comprises two high roll units displaced at 90 degrees relative to each other with hard metal or similar ring shape rolls, which are supported on one end only, the rings being clamped accurately onto their drive shafts against locating stops. The rings have a number of round (bastard round)-oval grooves. On maintaining a minimum rolling ring width for large grooves, >=1 of the adjacent round (bastard round) and one oval groove provided for a fixed deformation sequence on each ring, while for smaller grooves >=2 each of directly adjoining round (bastard round) and oval grooves and/or two adjacent round (bastard round) and oval grooves separated by an intermediate oval groove are provided on each ring. Moreover a fixed deformation sequence is adhered to on the rings and each roll unit is fitted with a compensating spacer, which assures a constant distance between the roll groove centre lines and the plane against which the rings are mounted. The system permits the use of rings with excess number of grooves, which are taken into use as grooves are worn out. It thereby permits maximum utilization of the expensive hard metal rings.

Title: Selector wiper fixed contact with electrostatic screening - has mushroom shaped overlapping hollow electrodes conveying current through walls
Inventor: HEINZ RUDOLF
IPC: H01H1/62
Filed: 1973-09-07
Abstract: The fixed contact for the wiper has two electrodes overlapping the contact nose, one above and one below. They are hollow and shaped like mushrooms. The nose is clamped by a double prong wiper contact, which means that the current divides and flows in opposite directions through the walls of the hollow electrodes to the cable. This produces opposite polarity field as the contact surfaces and hence an attractive force between the two prongs. The result is an improved surface contact and a reduction in contact resistance. The insulator is connected to the base of the cylindrical body and the joint has facility for passing a cooling medium.

Title: Regenerative thermal engine - works on two stroke principal with rotary valve and uses internal combustion
Inventor: MUELLER WILLI
IPC: F02B25/06
Filed: 1973-10-05
Abstract: The regenerator is rotated at engine speed in the cylinder head and parallel to the crankshaft axis. The gas exchange takes place in two cycles, on one side by the piston close to its lower bottom dead centre as it uncovers transfer ports in the cylinder walls and on the other side by the rotary valve which contains the regenerator with its hot side and cold side. A compressor driven by the engine forces scavenging air through the transfer ports when they are uncovered by the piston to press the exhaust gases through the opening in the regenerator hot side, give up most of their heat, and leave by the cold side. A fuel injector sprays fuel at a tangent to the incoming hot gases at top dead centre of the expansion stroke.
