Abstract: Disclosed embodiments include an open cell, molded polyurethane foam comprising the reaction product of a reaction mixture comprising: an isocyanate mixture; and a polyol formulation, comprising a glycerin-initiated, alkylene-oxide capped natural oil polyol having a molecular weight of between 3,000 and 8,000 and a polydispersity index (PDI) of between approximately 1.5 and 2.5, wherein the PDI is defined as the ratio of the weight-average molecular weight, Mw, to the number-average molecular weight, Mn.

Abstract: A cutting machine for cutting metal, comprising: an understructure, rails (8), a driving trolley (2), a driven trolley (3), a cross beam (1), a transverse driving device (4), a hoisting device (6), a tow chain (9), a rail cleaning device (11), a torch support (10) and a software control system. The rails (8) with a circular cross section are parallel mounted on the understructure, and the driving trolley (2) and the driven trolley (3) move synchronously on the rails (8). An automatic longitudinal adjusting device (7) is provided at the driving trolley (2) and at one end of the drawn cross beam (1), and the driven trolley (3) is rigidly connected to the other end of the cross beam (1). Longitudinal driving devices (5) are installed symmetrically at the lower parts of the driving trolley (2) and the driven trolley (3). The longitudinal driving devices (5) comprise rack and pinion and guiding mechanisms for adjusting the distance between the rack and the gear by elastically sliding.

Abstract: A method for configuring a service and a method and apparatus for rate matching in a TD-SCDMA system, this method for configuring the service includes: taking that a check bit puncturing ratio should be more than 7i+a or less than 7i?a as a newly added constraint condition, and the check bit puncturing ratios of each configured service being outside a range of [7i+a, 7i?a], the method for rate matching includes: when puncturing each path of check bits of the current data block, if a difference between a position Pk of kth reserved check bit calculated according to a method defined by the service and a previously determined position NPk?1 of k?1th reserved check bit is a positive integral multiple of 7, determining a position NPk of kth reserved check bit as Pk plus 1 or Pk minus 1, and Pk plus 1 and Pk minus 1 requiring carrying out alternately.

Abstract: A transverse-longitudinal perpendicular automatic adjusting apparatus used for a cutting machine is disclosed. The automatic adjusting apparatus comprises a cross beam (8), a driving trolley (5), a driven trolley (7), a rotating shaft (1), a rolling bearing (2), a driving connecting plate (3) and a disc spring (4). The cross beam (8) is a drawn cross beam. The driving connecting plate (3) is connected to a bottom surface of the cross beam (8). A bottom surface of the cross beam is rigidly connected with a driven connecting plate (6), which is connected with the driven trolley (7). The apparatus ensures stable operation and is inexpensive. The apparatus is easy to adjust, install and manufacture.

Abstract: A paving material suitable for pedestrian and bicycle trails combines an asphalt-rubber binder and crumb rubber aggregate. The binder is approximately 15%-30% finely divided recycled tire rubber and approximately 70%-85% asphalt by weight. Additives can be included to increase chemical bonding between the asphalt and rubber. The crumb rubber aggregate can be ground tire rubber. In the preferred embodiment, the asphalt-rubber binder and crumb rubber aggregate are combined in a roughly even ratio by weight, although the proportion of binder could vary from approximately 40% to 60%.
