PURPOSE:To obtain a package having good unwinding performance in high speed longitudinal taking by using a cylindrical coreless carbon fiber having a specified apparent winding density and a specified twill angle in the innermost layer. CONSTITUTION:The winding density is within the range of 0.3-1.0g/cm<3>. With a lower density, a little vibration will cause a package to get out of shape. On the c...

A transport cart for material carriers such as bobbins or drums having threads or other elongated material wound thereon, has a cart frame with wheels and a tilting frame journalled in said cart frame. The tilting frame carries two parallel skids for supporting a material carrier on its rollers. The tilting frame is tiltable between a first position in which the skids extend horizontally for loadi...

A quick connect fitting for tubing which can be inserted into a pre-assembled fitting where it will become sealed and locked against pull-out. A main fitting body has an open-ended recess in which is located a movable piston to seal against the body and an inserted tube. The piston wedges over a conical extension on a sealing gland retained by a snap-on cap, the gland and the cap having complement...

A solid-state electrosurgical generator is disclosed which provides output waveforms that are optimized for electrosurgical fulguration. The fulguration output circuitry consists of a radio-frequency tank circuit which is periodically pulsed to produce a periodic damped-sinusoidal output waveform. However, the damping factor is sufficiently low so that many cycles of the waveform occur between per...

An electronic ski binding including orthogonal, obliquely mounted transducers for detecting oblique components of skiing forces applied to the binding. The binding may include isolation means for structure the transducers from the effects of ski bending. A means of mechanical compensation for the forces applied to the binding by the leaning of a skier may be included. A pivoted linkage between a s...

A method for altering the surface appearance or texture of a textile or other substrate comprises impinging the surface of the substrate (25) with a high velocity fluid jet (18) with water being a preferred fluid. The substrate is placed against a support (20), and a fluid stream having a peak dynamic pressure in excess of about 2068 kPa (300 p.s.i.g) is directed onto the fabric surface. Various m...

In the manufacture of bodies of foamed plastic material, a polymeric synthetic resin base material is mixed with a cross-linking agent, a foaming agent and at least one further additive. The resulting mixture is shaped without a decomposition of the cross-linking and foaming agent and is subsequently heated to effect cross-linking and foaming. In order to obtain bodies of foamed plastic materials ...

A laminate comprises an adherent in-mold thermoset coating composition on a thermoset polyester glass fiber substrate, the coating composition comprising essentially the reaction product of an unsaturated aliphatic fumarate polyester diol, a saturated polyester diol flexibilizer, a cross-linking aliphatic polyol having from 3 to 6 OH groups, a diisocyanate in an amount by weight sufficient to prov...

A coating composition for polyolefinic products, particularly films, which consists essentially of a solution of a three-component polymeric system comprising: (a) a vinyl or vinylidene copolymer; (b) a polymer or copolymer of acrylic esters; and (c) a polyester resin obtained by condensation. The coated products and the coating process are also described.

An improved expandable polymeric styrene particle is provided containing a blowing agent, a minor amount of pentaerythritol tetrastearate, overcoated with a minor amount of glyceryl monostearate. The improved particle results in a significantly reduced final mold cooling cycle in producing the finished molded article.
