Patent number: 8852380Abstract: A method of manufacturing a lightweight multilayer heat reflective concrete cure blanket having a moisture-impervious top outer layer, a moisture-impervious bottom outer layer, and the top and bottom layers sealingly connected to each other at the boundaries of the layers to form a moisture-impervious chamber between the first and second layers. The chamber includes at least one bubble type insulative layer therein, and the bottom surface of the blanket comprises a heat reflective material to reflect heat emanating from the concrete when the blanket is placed over the concrete. In a further embodiment, heat reflective material is applied to at least one inner bubble type layer to reflect additional heat which radiates from the concrete through the insulative layer and back towards the concrete.Type: GrantFiled: March 19, 2013Date of Patent: October 7, 2014Assignee: Midwest Canvas CorporationInventor: Gary Handwerker

Patent number: 7726710Abstract: Embodiments described herein provide a cover, and a method for using the cover with a surface. One embodiment of the cover comprises a flexible, substantially planar member. A plurality of reinforcing members is attached to the flexible, substantially planar member. The plurality of reinforcing members is arranged on the flexible, substantially planar member so that the flexible, substantially planar member can reliably support a load. A plurality of manipulation members is operatively associated with the plurality of reinforcing members. The plurality of manipulation members is accessible to a lifter so that the lifter can apply force to the plurality of reinforcing members and can move the load reliably supported by the flexible, substantially planar member.Type: GrantFiled: January 7, 2008Date of Patent: June 1, 2010Assignee: Midwest Canvas CorporationInventor: Gary Handwerker

Patent number: 6317902Abstract: An improved lightweight, multi-layer, reflective swimming pool cover containing two thermoplastic layers. The top layer has a dark-colored polyethylene film and the lower layer has a polyethylene film with a aluminum concentrate, or other suitable reflecting material, deposited thereon along the entire layer, thereby becoming a reflective surface. The layers are suitably bonded together to form a water and air tight seal so as to provide the cover with a reflective surface on which are integral reflective solar heating and insulative pockets configured in a predetermined spatial relationship to each other. The cover acts to continually reflect radiating heat back into the pool and provides an effective and enhanced insulation barrier against radiant heat loss from the pool.Type: GrantFiled: May 23, 2001Date of Patent: November 20, 2001Assignee: Midwest Canvas CorporationInventor: Gary Handwerker
