Title: Semiconductor surface polishing medium - prepd. by two-stage counterflow elutriation and agglomerant admixture
Inventor: JENTZSCH JOACHIM
IPC: H01L21/306
Filed: 1973-07-19
Abstract: A polishing medium for semiconductor surfaces is produced by continuous addition of a polishing powder to a sedimentation liquid, to form a suspension. A counterflow elutriation separates the coarse fraction above a certain particle size. An agent which is soluble in the remaining fine grained suspension and acts as an agglomerant for the solids content is mixed with it. A final elutriation results in a solids concn. of the polishing suspension. This process can be carried out continuously and the elutriation, carried out as a counterflow sedimentation, considerably reduces the time required.

Title: Rheological drilling fluid props - measured in actual well by apparatus with temp pressure and pressure differential meters
Inventor: MEGYERI MOIHALY DR
IPC: E21B21/08
Filed: 1973-11-20
Abstract: The rheological properties of drilling fluids are measured by fitting the appts. at the end of the drill string, with the drilling fluid passing down in the bore of the drill string and up in the annulus between drill string and well walls. The appts. has a smaller passage area than the drill string and the pressure loss caused thereby is measured continuously. This provides truer results because the conditions are not those simulated in a pure laboratory test but field conditions. The tests can be arranged to ensure a laminar flow for the drilling fluids.

Title: Medical use electroacoustic transducer - for electrical signals from scraper on renal calculus, with threshold switch and amplifier
Inventor: WILK KLAUS
IPC: A61B5/06
Filed: 1973-11-21
Abstract: Electroacoustic transducer for signals produced by an electromechanical converter when a scraper scratches on a hard object such as a kidney or urinary bladder calculus has a signal amplifier and loudspeaker. The sound generator has a circuit with a threshold value switch with a fixed, preset response threshold, above which it switches to an excitation current source with adjustable current amplitude. The amplifier has means for altering the gain so that preset signal fractions lying above a desired amplitude threshold of the amplifier input signal exceed, after amplification, the fixed response threshold of the threshold switch. Power requirements are min., and annoying permanent acoustic noise is eliminated, selectively retaining diagnostically valuable amplitude fractions of the electrical signals.

Title: Glass inlay for concrete slabs - uses mould with surface indentations for glass beads set in concrete and plastics
Inventor: WOLF ARND DIPL ING DR ING
IPC: E01F9/04
Filed: 1974-12-06
Abstract: The glass beads are put into a mould with an uneven pitted surface and a mixture of concrete and molten plastic is added to form the surface layer. The mould is then filled with a filler concrete which is rammed in. The uneven surface of the top layer of the slab or stone ensures that the beads protruding from the concrete are all at slightly different levels, thus improving the reflective effects. The setting of the glass components also improves its resistance to frost, which could cause cracking.

Title: Chain conveyor tensioner - has semicircular guide plate pivoted by drive on axis clear of curve centre
Inventor: SORG HANSPETER DIPL ING
IPC: B65G23/44
Filed: 1975-03-15
Abstract: At the return end of the chain is a semicircular guide plate, equipped with an adjusting drive. The plate (4) pivots on an axis (5) clear of the centre of the chain curve, and the drive (10, 11) acts on the plate at a point clear of this axis, being typically a ram (11), a weight acting via a guide pulley, or a spring-loaded screwed spindle. The design is simple in construction and subject to very little wear. Only a relatively small amount of force is required to produce the necessary tensioning effect and if required this force can be further reduced by increasing the distance between the swivel axis and the contact point between the drive and the plate.
