Abstract: The present invention describes a method of organic synthesis for N-homocysteine thiolactonyl retinamide, a compound that has anticancer and antiatherogenic properties.

Abstract: An apparatus for clearing and cleaning of engine cylinder exhaust ports wherein access is gained through the spark plug receiving bore. The apparatus consists of a unitary cleaning tool having a handle end and a bent tool end extending at approximately 90.degree. from said handle end, the tool end of the implement having a terminus of selected diameter and posteriorly extending lip formed thereon. In addition, the device utilizes a template which is readily affixed to the engine cylinder head to provide manipulative direction in cleaning selected ones of the exhaust ports of the engine.

Abstract: A crane device having a track supported main frame with a trolley rollable on the main frame at right angles to the direction of travel of the main frame and with a carriage rotatable on the trolley. The trolley may consist of a single load trolley or it may consist of a load trolley and a trolley for carrying an operator's cab with each of the trolleys being provided with a rotatable carriage. The load trolley is adapted, via cables connected to the carriage, to engage a load such as a ladle. The ladle has a stopper which can be retracted by remote control from the operator's cab and is, likewise, tiltable for discharging slag and residue therefrom.

Abstract: A mobile, abrasive, surface treating device in which an impeller fan is disposed within a circular housing to direct a stream of abrasive material from a hopper against the treated surface in a blasting fashion. A movable frame assembly supports the open face of the housing in abutment with the treated surface, and a resilient element on the housing prevents dispersal of the abrasive material. The spent abrasive material is recovered and recycled by a continuous bucket conveyor system. Fluid motors cooperate with a system of winches and cables to control movement of the device over the treated surface.
