Title: Protected membrane roof system for high traffic roof areas
Inventor: RILEY ELIZABETH
IPC: E04D5/06
Filed: 1987-04-06
Granted: 1991-10-08
Abstract: ABSTRACT     An insulated roofing system is provided in which a waterproof membrane is applied to the roof deck.  Extruded panels of closed cell polystyrene foam are provided on top of the membrane, thus protecting the membrane from thermal cycling, ultraviolet rays, and physical damage.  The foam panels provide excellent insulation and are resistant to water.  A waterproof plastic film is bonded to the undersurface of each panel positively to exclude water.  The foam panels are cut mechanically or are grooved to provide on the upper surface integral ribs spaced by channels.  Concrete panels are said directly on top of the polystyrene foam and rest gravitationally on the ribs.  The ribs provide for ventilation and moisture removal on hot, dry days.        Removal of water vapor is enhanced by the increased area exposed to the ambient environment and derived from the cratered surfaces generated by cutting sections out of the foamed plastic panels.  The composition, texture, and the physical contour or configuration of the cut surfaces bounding the cut grooves or channels formed in the foam plastic panels enhance the dissipation and dispersion of moisture, as compared with surfaces covered with a dense skin such as is produced upon generating the channels in an extrusion process.

Patent CA-1330350-C (CA)
Inventor: SCHMITT THOMAS M
IPC: C07C29/76
Filed: 1987-09-17
Granted: 1994-06-21
Abstract: METHOD FOR PURIFICATION OF ETHYLENE GLYCOL                 Abstract of the Disclosure The invention discloses a method for purifying ethylene glycol by using an ion exchange resin.  The anion exchange resin adsorbs aldehyde impurities from the ethylene glycol. A basic anion exchange resin is prepared in a bisulfite or a hydroxyl form.  The ethylene glycol passed through the column under air or nitrogen gas atmospheric conditions.  As a result, aldehydes are absorbed as their bisulfite adducts.  Subsequently, the ethylene glycol may be treated by carbon adsorption to improve the UV/visible absorbance.  A weakly basic resin such as Amberlte? IR-45 is preferred, but other anion exchange resins are also expected to be effective.

Title: Process for producing ethylene dichloride
Inventor: BUHS CHRISTOPH
IPC: C07C17/156
Filed: 1987-12-16
Granted: 1992-04-21
Abstract: ABSTRACT     PROCESS FOR PRODUCING ETHYLENE DICHLORIDE     The oxychlorination process for producing ethylene dichloride is carried out by reacting ethylene with hydrogen chloride and oxygen in an oxychlorination reactor.  Thereby, ethyl chloride and perhaps vinyl chloride are produced as by-products.  The effluent from the reactor is at least fractionated into an ethylene dichloride-rich fraction (I) and an ethyl chloride-rich fraction (II) so that fraction (I) contains less than 50 percent of the total weight of ethyl chloride produced in step a) and the sum of the weight of ethylene dichloride and vinyl chloride in fraction (II) is less than 30 percent of weight of ethyl chloride in fraction (II).  The ethyl chloride-rich fraction (II) is subjected to a cracking reaction in the presence or absence of an inert diluent wherein ethyl chloride is converted into ethylene and hydrogen chloride in the presence of a catalyst.  The total weight of ethylene dichloride and vinyl chloride is less than 5 percent, based on the combined weight of ethyl chloride and any inert diluent.  This process  provides an improved means for handling by-products of ethylene dichloride production.

Abstract: ABSTRACT OF THE DISCLOSURE      A material handling vehicle is provided which is capable of operation on the highway, off-road and on railroad tracks.  The vehicle includes a lower truck chassis having an engine and a first operator's cab and an upper structure which includes an upper structure operator's cab and a material handling implement.  In the travel mode of operation, the engine is directly connected to the torque converter of a powershift transmission to provide a rotational output to the drive wheels.          In the off-road or remote operating mode of the excavator, the transmission is controlled so as to prohibit the connection between the torque converter and the transmission gears.          However, a power take-off on the transmission is coupled to a hydraulic pump which provides hydraulic fluid under pressure to a hydraulic motor which, in turn, may provide rotational power to a secondary input to the transmission to provide drive power.          In the railroad operating mode of the present invention, the engine is coupled by means of the torque converter to the transmission to provide driving power.  In addition, the engine is coupled to the hydraulic pump to provide hydraulic fluid under pressure to power the excavator functions.  The upper structure cab includes two throttle controls for controlling engine speed while operating in the remote operating mode.
