摘要： A vinyl structure is made by a specific technique which yields an embossed top layer and a foam base. The embossed top layer is made of a material which fuses and which is embossable at a lower temperature than the base foam. After the two layers are formed, the product is heated to a point which will soften the top layer, but not the foam base and consequently embossing will affect only the top layer.
摘要翻译：乙烯基结构通过产生压花顶层和泡沫基材的特定技术制成。压花顶层由熔化的材料制成，并且在比基底泡沫更低的温度下可压花。在形成两层之后，将产品加热至软化顶层的点，而不是泡沫基底，因此压花仅影响顶层。

摘要： Manufacture of expandable styrene polymers which on expansion provide oval saddle-shaped discs suitable for use as bulk cushioning material. In the process, cylindrical extrudates of expandable styrene polymers are deformed at form 70* to 90*C by means of rollers to form strands of oval cross-section, which strands are then sliced to form discs by cutting in the direction of the short axis of said oval cross-section.

摘要： A METHOD OF FORMING A CAST FOR A PORTION OF A LIVING BODY COMPRISES BRINGING A SHEET OF A FOAMED, AT LEAST PARTIALLY CORSS-LINKED, THERMOPLASTICS MATERIAL, SUCH AS POLYETHYLENE, TO A TEMPERATURE WHICH PLASTICIZES IT AND RENDERS IT PLIABLE WITHOUT DESTRUCTION OF ITS FOAMED, CELLULAR CHARACTER. THE PLIABLE THERMOPLASTICS MATERIAL CAN BE SHAPED DIRECTLY ONTO A LIVING BODY. AFTER COOLING THE MATERIAL CAN BE SHAPED DIRECTLY ONTO A LIVING BODY. AFTER COOLING THE MATERIAL SETS IN THE CONFIGURATION OF THE BODY. THE TECHNIQUE CAN BE USED IN THE FORMATION OF ORTHOPAEDIC SUPPORTS. THE MATERIAL MAY HAVE A REINFORCING MEMBER EMBEDDED WITHIN IT.

摘要： This disclosure relates to a molding process and the plastic sheet produced by said process. The process is characterized by a calender pressing a sheet of thermoplastic foam against a heated roll mold having a multiplicity of close-spaced needle like holes in its surface, pressure-molding the outer layer of the base foam-plastic material sheet into the needle like holes, by strongly applied external pressure an internal foaming pressure and removing said formed plastic sheet by cooling the sheet just prior to removal and removing the sheet in a hot surrounding atmosphere, thereby stretching the needle-like molded piles to from 3 to 5 times the depth of the needle-like holes.

摘要： A plate blank adapted to be selectively etched by radiant energy to form a desired relief pattern thereon for forming a relief printing plate or for decorative or artistic purposes consists of a sheet of thermoplastic material having voids therein that collapses within its own volume when heated to its softening temperature by applying a particular type of radiant energy, such as infrared radiation. A template of the desired pattern, made of material which reflects the type of radiant energy to be applied for collapsing the sheet material, is placed or formed on the surface of the sheet. The radiant energy thereafter heats and collapses the exposed areas of the sheet but is reflected from the areas that are shielded by the reflective template patterns which are therefore left in relief.
摘要翻译：适于通过辐射能选择性蚀刻以形成凸版印刷板或用于装饰或艺术目的的所需浮雕图案的板坯由其中具有空隙的热塑性材料片组成，其中当其被加热到其中时，其在其自身体积内塌陷通过应用特定类型的辐射能（例如红外辐射）来软化温度。在片材的表面上放置或形成由反射要用于塌陷片材的辐射能的类型的材料制成的所需图案的模板。此后，辐射能量加热并折叠片材的暴露区域，但是从被反射模板图案屏蔽的区域反射，因此这些区域因此被释放。

摘要： AN APPARATUS FOR MAKING THERMOPLASTIC CELLULAR PLASTIC PRODUCTS AND WHICH HAS PREFORM AND FINAL FORMING STATIONS. THE APPARATUS FEATURES THE USE OF A PAIR OF FRAMES WHICH ARE INTERCHANGED AT THE SAID PREFORM AND FINAL FORM STATIONS BY A TRANSFER MECHANISM. EACH FRAME IS CHARGED WITH THERMOPLASTIC BEADS WHILE HELD BETWEEN PLATENS AT THE PREFORM STATION FOR THE INTRODUCTION OF HEAT TO FORM A CELLULAR PREFORM BLANK AND IS THEN MOVED TO THE FINAL FORM STATION WHERE THE BLANK IS GIVEN A FINAL SHAPE BETWEEN ANOTHER PAIR OF PLATENS.
