Patent CA-2081378-A1 (CA)
Inventor: HOERMANSDOERFER GERD
IPC: C09K5/06
Filed: 1991-12-31
Abstract: (57) Abstract The invention relates to lalent heat storage agents for storing thermal energy, The proposal is for the use of mixtures or var-ious perchlorates or perchlorates-hydrates with other organic substances or inorganic salts or hydrate salts. As is known, pure lithium perchlorate trihydrate melts at a temperature of 94.3 °C and, with a value of 306 J/g, has a markedly high melting en-thalpy. Its density of 1.89 also gives the very high volume-specific figure of 578 J/cm3. Because, however, its melting point is close to the boiling point of water it is not of practicable use in upressurised systems in which water is the heat conveyor. However, the various mixtures proposes by the invention have lower melting points in a broad temperature range, also with very considerable melting enthalpies which are almost the same or not very much lower than that of the pure initial sub-stances.

Title: Sodium borohydride catalyzed disproportionation of cycloorganosilanes
Inventor: BANK HOWARD M
IPC: B01J31/26
Filed: 1992-12-01
Abstract: SODIUM BOROHYDRIDE CATALYZED DISPROPORTIONATION            OF CYCLOORGANOSILANES                           ABSTRACT           The present invention is a process for the disproportionation of cycloorganosilanes using sodium borohydride as a catalyst.  The process requires the presence of a hydrogen and a cycloorgano-substituent bonded to a single silicon atom, where the cycloorgano-substituent is a radical selected from a group consisting of aryls, substituted aryls, cycloalkyls and substituted cycloalkyls. The present process is especially useful as a continuous process for the disproportionation of phenyldichlorosilane to diphenyldichlorosilane and dichlorosilane.

Title: Wheel construction for vacuum cleaner
Inventor: SOVIS JOHN F
IPC: A47L9/00
Filed: 1992-12-22
Abstract: WHEEL CONSTRUCTION FOR VACUUM CLEANER                 Abstract of the Disclosure A wheel assembly for a vacuum cleaner includes an axle, a collar, and a wheel.  The axle is cylindrical and has inward and outward ends.  The inward end is attached to a housing of an associated vacuum cleaner and the outward end has locking projections extending radially outwardly from an axial centerline.  The collar has an outward end which includes collar gaps.  When the axle is fitted within the collar, the locking projections fit into the collar gaps preventing rotational movement between the collar and the axle.  The wheel has a wheel bore therethrough.  When the wheel is fitted over the collar and axle, so that the collar and axle fit within the wheel bore, the locking projections snap radially outwardly against an outer surface of the wheel, thereby holding the wheel, collar, and axle together and permitting rotational movement between the wheel and the collar.

Abstract: A  combined  stability  cane  and  device  for assisting a handicapped person in traveling up and down a flight  of  stairs  having  vertically  spaced  steps  is disclosed.   A rectangular block member or platform has a flat upper surface within which a connector mechanism is provided  at  its  central  area,  and  a  second  connector mechanism is provided in the upper surface adjacent one of the sides of the block member and opposite the central area. A  walking  cane  having  a  cooperative  connector mechanism  adjacent   its lower   end   is   provided  to alternatively rigidly connect the same to one of the two connector mechanisms  in the upper surface of  the block member.   When  the  cane  is  connected  to  the  connector mechanism  at  the  central  area  of  block  member,  the combination  functions  as  an  excellent  stability cane. When  the  cane  is  connected  to  the connector mechanism adjacent  one  side  of  the  block  member,  the  latter functions as a half-step which the handicapped person may utilize to  facilitate  travel up and down the steps by taking only a half-step at a time, at first on the block member and then upon the next step, thereby reducing the elevation change required through a series of half-steps. Alternatively, the walking cane may be disconnected from the block member  so  as  to use the same  in  its  normal manner.

Title: Surface friction enhanced geosynthetic clay liner
Inventor: CARRIKER RICHARD
IPC: E02B3/12
Filed: 1994-03-23
Abstract: ABSTRACT    A friction enhancing material is applied to at least one surface of the geosynthetic clay liner.   The placement of friction enhancing material on the surface of the liner that engages a slope or embankment of a landfill helps the liner maintain  its  position during and after  installation.   The improved frictional contact between the liner and the slope or embankment permits use of bentonite liners on steeper slopes or embankments and therefore enables more efficient construction of landfills. The friction enhancement material may also be applied to the surface to improve contact between the upper surface of the geosynthetic clay liner and the cover soil.  The friction enhancement material may be high density polyethylene,  EVA, rubbers and other polymeric materials.
