Title: Bottle teat for babies - comprises head with aperture, narrowest cross=section of which has cylindrical channel section
Inventor: KESSELRING MICHAEL
IPC: A61J11/00
Filed: 1990-02-21
Abstract: The foremost end of the test has a channel shaped aperture with a narrow cross section (5) in the area between its ends. The transition between the narrow cross section and the inflow and outflow sections of the channel shaped aperture is continuous or discontinuous. The narrowest cross section of the aperture is formed by an extent in the flow direction of a channel section (5) with constant dia. which can evolve discontinuously into the widened parts (4) for inflow and outflow.  Flow resistance is thus reduced, and the conicity can have a somewhat larger opening angle, so that also a larger ridge which may form remains ineffective. USE/ADVANTAGE - As a teat for a bottle employed for feeding fluids to babies, with a suction aperture of defined cross section which is not prejudiced by ridge formation at the inflow and outflow sides.

Title: Aq. ozone preparations for ozone therapy and microbicidal use - contain dissolved ozone and are prepd. by bubbling an oxygen@-ozone mixt. through aq. soln.
Inventor: VIEBAHN-HAENSLER GEB HAENSLER
IPC: A61K33/40
Filed: 1991-01-12
Abstract: Aq. prepns. contg. dissolved ozone are new. The solns. contain clathrate forming substances. The solns. are physiological infusion solns., esp. dextran solns. or dextrin or starch solns. The aq. ozone prepns. can be prepd. by bubbling an oxygen ozone mixt. through an aq. soln. USE/ADVANTAGE - The aq. ozone prepns. are suitable for therapeutic (intravenous ozone therapy) and hygienic (e.g. algicidal, bactericidal, fungicidal, sporicidal, parasiticidal and viricidal) purposes. The solns. do not have the disadvantages associated with prepns. previously used in ozone therapy as they contain ozone itself (not a reaction prod. of ozone) and the smallest possible amt. of gaseous oxygen as the ozone is selectively dissolved. The solns. are suitable for ozone therapy for circulatory disorders and viral diseases. In an example, in order to achieve an ozone conc. of 10 micro g/ml soln., a phosphate buffer soln. of pH 6.9 (0.023 mol Na2HPO4, 0.042 mol NaH2PO4) was treated for 10 min. at room temp. with an ozone/oxygen mixt. contg. 60 micro g/ml ozone. The amt. of soln. was 200 ml (height of water column 15 cm). For a dextran soln. (m. wt. 40000, 10%) the ozoning time was 5 min. A standard dose of 1000 micro g ozone per treatment required 100 ml of an ozone infusion soln. of ozone concn. 10 micro g/ml.

Patent DE-4117745-A1 (DE)
Inventor: WILL GUENTHER DR
IPC: B28B1/26
Filed: 1991-05-30
Abstract: The invention relates to porous, water-absorbent plastics mould material for use in the forming of ceramic castings from ceramic moulding materials. According to the invention they contain short fibres of length 1-6 mm in a quantity of up to 4 weight% with respect to the weight of the plastics content, as filler. The invention also relates to a process for producing these mould materials and their use in the forming of ceramic castings. Shrinkage and mechanical properties are considerably improved by the addition of short fibres, even in a very small added quantity. By producing the mould materials from water-in-oil emulsions the permeability of the mould materials can be adjusted within a wide range by controlling the degree of dispersion of the emulsion, so that both pressure-less and pressurized ceramic body formation and controlled release of the ceramic body from the mould by compressed air without the use of an aid become possible.
