Title: Perfume composition with deodorizing or antiperspirant action
Inventor: HOLZNER GUNTER
IPC: A61K8/11
Filed: 1990-01-25
Abstract: Case 3580 MIG/BLD/21.12.89 PERFUME COMPOSITION WITH DEODORISING OR ANTIPERSPIRANT ACTION                             ABSTRACT Personal care composition having deodorant or antiperspirant activity and containing, in addition to an active deodorant or antiperspirant base, a perfuming base, either in the form of an aqueous emulsion, or in microencapsulated form. The perfume base is combined with a film-forming substrate and an emulsifying agent.       The film-forming substrate contains either essentially polyvinyl-pyrrolidone, or a mixture of the latter with one or several compounds chosen from polyvinylacetate, polyvinylalcohol, dextrins, natural or modified starch, vegetable gums, pectins, xanthanes, carboxymethylcellulose, methylcellulose, hydroxyethyl-cellulose and lipoheteropolysaccharides. The emulsifying agent is chosen from mono- or diglycerides of fatty acids, esters derived from the combination OI fatty acids with sorbitol or with a saccharide, or their alkoxylated derivatives, or an ester of tartaric, citric, ascorbic or lactic acid.       The said composition has the advantage of releasing the volatile constituents of the perfume at the appropriate moment by the action of a source of moisture, in particular sweat. It also has the advantage that it gives rise to a re-encapsulation in situ, for example on the skin itself, of active constituents in the drying phase. It is suitable in particular for the manufacture of articles for personal care, such as deodorants and antiperspirants in the form of sticks, roll-on devices, smooth-ons or aerosols and pressure vaporisers.

Title: Mesa fabrication in semiconductor structures
Inventor: SWINDAL JAMES L
IPC: H01L29/84
Filed: 1990-01-29
Abstract: Abstract MESA FABRICATION In SEMICONDUCTOR STRUCTURES      Semiconductor structures for electronic use, such as for example a silicon-glass-silicon pressure sensor (Fig. 3), include mesa or pedestal structures (12A) extending up from silicon substrates (12).   In the invention the mesa structures are fabricated in an oxidation process applied in a cyclical fashion (steps 1-3 through 1-5 of Fig. 1). Each  cycle  includes  a  photolithographic  operation  to protect  the  previously  grown  oxide  on  the mesas  from etching.    During  each  cycle  less  oxide  is  grown  (or conversely silicon consumed)  on the mesas  than  in the preceding  cycle,  while  equivalent  amounts  of oxide are grown on non-mesa areas in each cycle.   As a result, the tops of the mesas get higher and higher above the surround-ing areas in each cycle.  In order to prevent the leaving of  any  oxide  "scraps"  in  a  non-mesa  area  during  the oxidation steps,  resulting from a  flaw in the mask,  a double exposure process is used, utilizing two completely independent masks, with a positive working photo-resist.

Title: Electronically controlled wheelchair
Inventor: ENZINGMULLER HANS-JOACHIM
IPC: A61G5/04
Filed: 1990-08-16
Abstract: Abstract of Disclosure:            The present invention relates to an electronically controlled wheelchair, comprising electric motors for driving the wheelchair wheels; electrically operable parking brakes for the wheels of the wheelchair; an electronic control circuit for the electric drive motors; and a manually operable control switch for conditioning the electronic control circuit, inclusive of interruption of the power supply to the electric drive motors and activation of the parking brakes in a neutral position of the control switch. In order that occurence of uncontrollable states of operation of the wheelchair, as may be caused in the control circuit by e.g. external electromagnetic alternating field, may be ended in a short time, according to the invention there is provided a neutral position detector detecting the neutral position of the manually operable control switch, which detector provides a motor stop signal while bypassing the electronic control circuit, when the control switch is in the neutral position, the stop signal interrupting the power supply to the electric drive motors. These advantages are ensured by a neutral position detector which in its various embodiments distinguishes itself from the conventional detectors of this kind by being principally constructed from a smaller number of component parts and/or more wear-resistant component parts. This structure enhances the reliability and permits detection of a narrower neutral position range.
