Title: Process for the preparation of alkyl glycosides and alkyloligoglycosides
Inventor: OBERHOLZ ALFRED
IPC: C07H15/04
Filed: 1991-10-25
Abstract: ABSTRACT            A process for preparing alkyl glycosides and alkyl oligoglycosides by acid-catalysed reaction of saccharides in an aqueous solution with short-chain alcohols at elevated temperature is disclosed.  According to the invention, the reaction is car-ried out in a counter-current reaction column, preferably at atmospheric pressure.  The process requires an equipment simpler than the equipment used for similar known processes and provides products of improved colour.  The products of the process are useful as intermediates in the preparation of long-chain alkyl polyglycosides, which have surfactant properties.

Abstract: INTEGRATED CIRCUIT TRANSPONDER WITH COIL ANTENNA IN A PNEUMATIC TIRE FOR USE IN TIRE IDENTIFICATION                 Abstract of the Invention A pneumatic tire has an integrated circuit transponder which, upon interrogation by an external RF signal, transmits tire identification and/or other data in digitally-coded form.  The transponder has a coil antenna of small enclosed area as compared to the area enclosed by an annular tensile member comprising a bead of the tire.  The annular tensile member, during transponder interrogation, acts as the primary winding of a transformer.  The coil antenna is loosely coupled to the primary winding and is the secondary winding of the transformer.  The coil antenna is substantially planar in shape, and, when positioned between the innerliner of the tire and its carcass ply, the transponder may include a pressure sensor responsive to tire inflation pressure.

Title: Drying of finely divided, expandable styrene polymers
Inventor: HAHN KLAUS
IPC: B29B13/06
Filed: 1992-02-13
Abstract: O.Z. 0050/42214 Abstract  of  the  Disclosure:  In order  to dry  finely divided, expandable styrene polymers having a particle size of from 0.02 to 3 mm, the bead polymers, in the form of a slurry in water, are freed from the majority of the water and subsequently exposed to a gaseous medium. The drying is carried out in two steps, by jointly conveying the bead polymer and a first gas  stream, warmed to from about 45° to 120°C,  through a flow dryer,  the ratio between the gas and the bead polymer being from 2 to 40 kg/kg, separating the bead polymer from the first gas stream, immediately transferring the bead polymer into a fluidized bed and treating the polymer with a second gas stream at from about 0° to 75°C. Styrene polymers ob-tained in this way are free-flowing and can be foamed without difficulty in commercially available prefoaming units. They are used, inter alia, in the construction industry,  for  example  as  aggregate  for  insulation plaster.

Title: Gas isolated disconnecting switch and gas isolated switching device
Inventor: OZAWA JUN
IPC: H01H31/32
Filed: 1992-05-07
Abstract: A gas isolated disconnecting switch provides a sufficient restriking surge suppressing function with no adverse effect on the operation of a circuit breaker in the system, enabling the circuit breaker to reliably interrupt a fault current.  In the closed condition of the switch, a main stationary member engages a main movable member, and an auxiliary movable member 17 engages an auxiliary stationary member.  A portion of an auxiliary conductor which passes through a cylindrical magnetic body is short-circuited by the main stationary member and the main movable member and there is no influence on the operation of the circuit breaker.  During an opening operation of the switch, the auxiliary movable member disengages with a time delay, whereupon the current flows through the portion of the auxiliary conductor that passes through the cylindrical magnetic body 9 whereby to achieve a sufficient restriking surge suppressing function.

Title: Prolonged occlusion treatment system
Inventor: SHORE RONALD N
IPC: A61F13/00
Filed: 1992-07-31
Abstract: ABSTRACT OF THE DISCLOSURE           The  healing  of  the  number  of  skin  disorders  is effectively enhanced by prolonged  continuous  occlusion and/or hydration.     Treating  these  disorders,  e.g.  psoriasis,   is significantly facilitated by occluding affected skin areas with a suitable barrier for a prolonged and continuous period of time.          Such occlusion is effective by itself, but is materially improved by concurrent topical administration of medicament useful  for treating the disorder.   In such cases, the prolonged continuous occlusion markedly  increases hydration which has  the  further therapeutic benefit of tremendously facilitating penetration of medicament.  The provided barrier is one with low water-vapor transmission or one which is water impermeable.   Within such framework, a treatment system has been devised which includes the application  of medication,  adhesive  or adhesion  enhancer and waterproof occlusive cover, and the removal of the occlusive cover, such as with an adhesive remover, after a prolonged period of at least three days.  Special kits having key components have also been prepared for this treatment system.

Abstract: A method and apparatus for distinctively and proportionally displaying windows on a computer display screen is disclosed.  The amount of time each of the windows presented to the display screen is active (also known as "in focus") is monitored. Upon receipt of a command from the user, the windows that were active a longer length of time are displayed more distinctively than windows that were active a shorter length of time.  More specifically, windows are displayed on the display screen having a window size proportional to the length of time each of the window were active.  For example, a window that was active 40% of the time will have a size that is 40% of the specified window tiling area. Windows that have not been active long enough to exceed a minimum window tiling threshold are displayed as icons outside of or under the specified window tiling area and are not included in the calculations of percentage of activity of the windows.

IPC: A61F13/26
Filed: 1993-07-14
Abstract: Abstract The invention relates to a sleeve (120) for use as an outer sleeve and/or inner sleeve for a telescopic applicator. The sleeve consists of a blank composed of a  plane-surface,  rectangular  length  portion  of  a flexible, cellulose-containing material. The two ends of the blank are connected to one another to form a joining  seam  (132)  extending  in  the  longitudinal direction of the sleeve  (120),  the two longitudinal sides  of  the blank  forming the  ends  of  the  sleeve (120).  At  least  fore-edges  (142,  144)  of  the  two interconnected ends of the blank which are located on the outside of the sleeve (120) are arranged parallel and close against one another and together are aligned with the circumferential surface  (140) of the sleeve (120),  so that the joining seam (132)  is essentially smooth  and  invisible  on  the  outside  of  the  sleeve (120).  As  a  result  of  this  design,  an  economical production of the sleeve  (120) is achieved and, when the sleeve is used for an applicator for introducing articles into a human or animal body cavity, the danger of  irritation or injury to  skin tissue  is reliably prevented.
