Abstract: Flexible   concrete   structures   resemble elongated rope-like articles having an outer textile casing in the form of a mono-tubular body with a continuous inner bore filled with dry cementitious material.  The concrete ropes are naturally permeable to water for controlled chemical hydration for maximizing structural values and load bearing properties.  The flexible concrete ropes may be employed in a wide range of applications in masonry and cement construction,   such  as  caulk  filler  between foundations and roadways; as convenient mortar ropes in the reinforcement and stabilization of stone, rock, brick and block structures, like culvert bridges, drainage ditches, railroad  roadbeds;  temporary  templates  for  A-frame structures, and as chocks for dry foundations.  Flexible concrete rope articles can be wetted and woven into grids and lattice structures for use as fencing, gates, grids for fireplaces  and grills or  fabricated  into  subterranean anchoring supports for posts and signs for the elimination of large amounts of pourable concrete normally required.

Patent CA-2145109-A1 (CA)
Inventor: WELHOUSE HAROLD L
IPC: A47J37/10
Filed: 1995-03-21
Abstract: An improved one-sided embossing process for manufacturing low-fat non-stick frying cookware is provided.  The process provides a textured cooking surface free of sharp edges which increases the useful life of a non-stick coating applied thereto.          The embossed cooking surface of the resulting frying device comprises a series of wave-like grooves embossed in the surface of the pan.  The wave-like pattern of each groove is one-half cycle out of phase with its neighboring adjacent grooves to form an alternating pattern of outwardly extending lands and inwardly extending roots.  A raised portion or elevated surface is provided on the cooking surface disposed between the outwardly extending lands.  The elevated surface is the primary cooking surface and is further the location of the inevitable initial wearing of the non-stick material.  The remaining non-stick material, disposed in the grooves and between the roots is not subject to abrasive action and wears at a substantially slower rate.  The raised portions or elevated cooking surfaces disposed between the lands comprise less than 30 percent of the upper cooking surface and therefore less than 30 percent of the non-stick coating disposed on the upper cooking surface is exposed to the abrasive action of cooking utensils or cleaning utensils.
