Patent DE-19608361-A1 (DE)
Title: Perforated mat for generating air bubbles
Inventor: FRENKEL WALTER
IPC: A61H33/02
Filed: 1996-03-05
Abstract: A bed of nails is pressed into a sheet of elastic or semi-elastic material which is supported on a layer of felt in order to manufacture the mat. The material used can be polyvinyl chloride, rubber, leather, metal, glass fibre and some ceramics. The nails make microscopic tears in the material. The material round the holes partly springs back when the nails are removed. When the holes in the sheet are subjected to air pressure, the holes open up again to a degree depending on the air pressure.

Title: Adjusting natural frequency of double axis oscillatory construction
Inventor: LEE KI-BANG
IPC: G01C19/5755
Filed: 1996-05-23
Abstract: The method relates to a construction (32) which has a first sprung element (36) with a longitudinal axis which coincides with a first axial direction along which an electrostatic force is applied and a second sprung element (34) with a longitudinal axis at 90 deg  to the first axis. The width of the second sprung element is smaller than that of the first and the construction has a solid section (37). The natural frequency of the construction in the first axial direction is measured and that of a third axial direction at 90 deg  to the plane extending from the first and second axes. The thickness of the first element is altered to adjust the natural frequency relative to the third axial direction whilst maintaining the frequency relative to the first axial direction. The measurement steps and the alteration to the thickness are repeated until the natural frequencies relative to the first and third axial directions lie within a permitted tolerance band.

Patent DE-19718726-A1 (DE)
Title: Valve for vacuum sluices for powdered or fluid materials
Inventor: GOTTSMANN LUTZ DIPL ING
IPC: B65D90/58
Filed: 1997-05-02
Abstract: The valve plate (4) acts as sealing flange and collecting container for the granular or fluid material. The shape and size of the container is such that as the valve plate moves the sealing surface cannot be soiled by the material. The valve plate has two concentric sealing edges whose diameter and height are matched so that as the inner sealing edge adjoins the valve housing the outer sealing edge deforms the elastic seal in the valve housing to produce a sufficiently slight leakage rate. The valve has a guide tube (7) for the flow passing through the valve with a setting member independent of the drive of the valve plate. When the valve is opened the guide tube adjoins the valve housing with a metal seal. The diameter of the guide tube is smaller than the diameter of the adjoining outflow tube. The valve housing has a cleaning flange (3).

Patent DE-19733324-A1 (DE)
Title: Electrophotographic photoconductor with roughened substrate
Inventor: SENBA NAOYUKI
IPC: G03G5/10
Filed: 1997-08-01
Abstract: A process for roughening the substrate (1) of photoconductors for electrophotographic machine such as copiers or laser printers consists of sandblasting the surface using a medium with a grain size of not more than 25 microns. This is delivered from a nozzle (7) held at a predetermined distance from the substrate, which is mounted on a revolving table (8) turning at a predetermined speed, along the axial direction (PQ) at a fixed speed under air pressure (6). This gives a roughness to the surface of 5 microns or less. The roughened surface holds the photoconducting layer with even film thickness and quality. This ensures pictures without defects such as black flecks or empty patches and minimises risks of irregular loading and poor reproducibility. The process of roughening the substrate surface is inexpensive.

Title: Preparing active growth factor dimers from inclusion bodies in high yield

IPC: C12P21/02
Filed: 1997-11-05
Abstract: Preparation of biologically active dimers (I) of recombinant human growth factors (II) of the cysteine knot family is new starting from cellular inclusion bodies (IB). IB are solubilized in an aqueous alkaline, urea-containing medium in the presence of a reducing agent, applied to an ion-exchange column, renatured, (e.g. refolded, dimerized) and re-oxidized aerobically, by washing with a decreasing urea gradient. The product is then eluted with a gradient of an inorganic salt, and the product is further purified by conventional methods of protein purification. Alternatively IB's are dissolved in aqueous medium containing solubilizing agent and reducing agent, are optionally gel filtered under denaturing conditions, then refolded to association-competent monomers in the presence of a redox agent (and optionally of solubilizing agent), by gel filtration. The product, present in the gel filtration eluate, is then converted to active dimer using a redox agent.

Title: Procedure for impedance matching during coating of uncoated glass substrate with silicon dioxide
Inventor: KIM SA-HYUK
IPC: H01J37/32
Filed: 1997-12-22
Abstract: A procedure for impedance matching during the coating of an uncoated glass substrate with silicon dioxide has the following steps: matching an impedance of an oscillator and an impedance of a coating unit to output a matched voltage; transforming an amplitude of the matched voltage into a previously established amplitude to output a transformed voltage; stabilising the transformed voltage; evaluating a phase of the transformed voltage; and controlling the phase of the matched voltage corresponding to the phase of the transformed voltage. In the step for transforming the amplitude of the matched voltage, the matched voltage is carried by several condensers in series.
