Patent number: 11821151Abstract: When spreading aggregate material onto a layer of bitumen/wet bitumen, when forming a road surface, the aggregate is commonly spread from a truck in reverse, potentially causing accidents and injuries. Safety is improved by providing a spreading vehicle that can be driven in the direction in which it is spreading the aggregate material. This is achieved by providing a second driving cab and driver controls at a location that would normally be considered the rearward end of the vehicle. The second driver cab is above a conveyor system conveying aggregate material from a hopper of the vehicle to a spreader box. The second driver cab allows the vehicle to be driven in the direction it is spreading material, by a driver who is facing the direction of travel, and who can see if the vehicle is about to hit anything or run into a worker in the surrounding area.Type: GrantFiled: June 24, 2020Date of Patent: November 21, 2023Assignee: QFE HOLDINGS PTY. LTD.Inventors: Graham Laycock, Glenn Francis Hardiman, David Redfern Taylor

Patent number: 7779655Abstract: The invention provides a method for knitting fabric with bare spandex comprising: providing bare spandex yarn; providing hard yarn; drafting the bare spandex; knitting fabric from the hard yarn and the drafted bare spandex with the hard yarn and the drafted bare spandex plated in every course; and contacting the knit fabric with a continuous phase aqueous solution under conditions of temperature and pressure for a time sufficient to set the bare spandex without heating the knit fabric on a tenter frame above 160° C. in air having a relative humidity of less than 50%. The invention further provides a bare spandex-containing knit fabric containing spandex in every knit course that has been exposed to manufacturing process temperature no higher than 160° C. as shown by molecular weight analysis of the spandex and that exhibits wash shrinkage of less than about 14%.Type: GrantFiled: December 16, 2005Date of Patent: August 24, 2010Assignee: INVISTA North America S.á r.l.Inventors: Cheng-Yuan Chuang, Graham Laycock, Raymond S.

Publication number: 20070259583Abstract: Methods for making stretch fabric having stretch between 10% to 45% in the weft and/or warp direction are disclosed. A corespun composite elastomeric yarn is produced either (a) by low draft (2.7× or below) core-spinning of the elastomeric yarn, or (b) by pretreating the corespun composite yarn in steam or heated water at temperatures of at least 110° C. to reduce yarn power before dyeing or weaving. The fabric with such corespun composite elastomeric yarn in the weft meets end-use specifications without heat-setting.Type: ApplicationFiled: April 27, 2007Publication date: November 8, 2007Applicant: INVISTA NORTH AMERICA S.A R.L.Inventors: Graham Laycock, Raymond Leung, Tianyi Liao, Federica Stoppa

Publication number: 20070000066Abstract: The invention includes a dyed knit, elastic fabric comprising polyethylene terephthalate and spandex. The fabric has staining grade numbers of 4.0 or higher, as measured by staining of multifiber test fabrics in AATCC Test Method 61-1996-2A, and is dyed with disperse dyes comprising azo or anthraquinone molecular groups. The invention further includes a method for making the knit fabric.Type: ApplicationFiled: June 29, 2005Publication date: January 4, 2007Applicant: Invista North America S.a r.I.Inventors: Cheng-Yuan Chuang, Graham Laycock, Raymond Leung

Publication number: 20060021387Abstract: Circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece are disclosed that include a bare elastomeric material plated with spun and/or continuous filament hard yarns. The circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece are manufactured by a method that does not require a dry heat setting step. The method requires drafting the bare elastomeric material no more than about 7× its original length when knitting to form the circular knit, elastic, single jersey, French terry, or fleece fabric. The method includes contacting the knit fabric with an aqueous solution under very low tension and under conditions of temperature and pressure for a period of time sufficient to substantially set the elastomeric material.Type: ApplicationFiled: August 12, 2005Publication date: February 2, 2006Applicant: INVISTA NORTH AMERICA S. A R.L.Inventors: Cheng-Yuan Chuang, Graham Laycock, Raymond Leung, Peter Szanto, Fred Wynegar

The circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece are manufactured by a method that does not require a dry heat setting step. The method requires drafting the bare elastomeric material no more than about 2.5× its original length when knitting to form the circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece.Type: ApplicationFiled: August 12, 2005Publication date: January 19, 2006Applicant: INVISTA NORTH AMERICA S.

Publication number: 20050183463Abstract: Circular-knit, elastic, single-knit jersey fabric, of spun and/or continuous filament hard yarns with bare spandex plated in every course, has a cover factor in the range of 1.3 to 1.9, a basis weight from 140 to 240 g/m2, an elongation of 60% or more and low shrinkage. The circular knit, single-knit jersey fabric is produced by maintaining the draft of the spandex at or below 2× (100% elongation) and maintaining the finishing and drying temperature(s) below the spandex heat set temperature. The knit fabric meets the end-use specifications without heat setting.Type: ApplicationFiled: March 8, 2005Publication date: August 25, 2005Inventors: Graham Laycock, Raymond Leung, Elizabeth Singewald
