Title: Railway track mitre joint
Inventor: LI MARK J
IPC: E01B11/04
Filed: 1994-02-07
Abstract: The noise and vibration generated by the train rolling on the railway tracks greatly restrict the increase of the train speed. Although there have been numerous technological improvements to reduce the noise and vibration, one principal factor of the discontinuities of tracks due to the track joints has not yet been resolved completely. The said invention redesigns the shape of the railway track joint; changing the conventional right angle cut track joint to a 45° angle cut mitre joint. This new design allows a total elimination of the vibration and bump caused by the wheel contacting the conventional track joint. As a result, the said invention is able to provide a great potential for the development of the high speed train, with a smooth and comfortable ride.

Title: Composition containing body activated fragrance for contacting the skin and method of use
Inventor: BARR MORTON LAWRENCE
IPC: A61K8/37
Filed: 1993-09-22
Abstract: Described is a fragrancing composition having fragrancing components that are not activated until, e.g., application to the skin of a human. The composition is akaline or (if anhydrous) capable of producing an alkaline pH when in contact with water, prior to application, and includes (I) a vehicle for application of the composition, and (2) at least one potential fragrance that is at least one compound having little or no odor in the alkaline composition but which, e.g., is hydrolyzed in a lower pH environment to produce compounds having a relatively strong aroma. Upon application of the alkaline composition to the skin surface, the strong buffering capacity of the skin (the surface of which has a normal pH of 5.5-7.0) neutralizes alkalinity of the composition (lowers pH) so as to restore normal skin surface pH; the potential fragrance is then hydrolyzed at the lower pH to release the compound having relatively strong aroma.

Title: Continuous process for making a dialkyltin thiocarboxylic acid ester
Inventor: KOLIN KEVIN S
IPC: C07F7/22
Filed: 1995-05-10
Abstract: This invention provides a method for reducing fifty-fold the size of equipment required for making a given volume of alkyltin thioglycolic acid esters.      In said method, an alkyltin thiocarboxylic acid ester is made from the corresponding alkyltin halide and thiocarboxylic ester  in  a  continuous  process  that  requires  but  one agitated reaction vessel.   The organic reactants and an acid acceptor are added simultaneously to a reaction vessel equipped  with  agitator  impellers  and  containing  a sufficient level of water to provide an agitatable medium. Extremely vigorous agitation (at least about 75, preferably at  least  about  90,  turnovers  per  minute,  which  is sufficient  to  achieve  a  fluid  velocity  across  the impeller(s)  of at least about 50 feet per minute)  is employed to avoid side reactions which often cause the formation of a tenacious, stringy emulsion, the breaking of which requires a rather difficult and wasteful filtration. Continuous withdrawal of the reaction mixture from said reactor is commenced promptly after commencement of the additions and said mixture is continuously separated into an aqueous phase and an organic phase as it is withdrawn without the need of demulsification means.  The pH of the reaction mixture is greater than 7 but the maximum is about 8.2 and the temperature is from about 40 to about 80°C.
