Abstract: A plastic cup is provided of the thin wall variety having inner and outer spaced walls with an insulating air space therebetween. Successive cups in a telescoped stack seal effectively together so that a food concentrate or the like placed in the bottom of each cup will be protected against contamination and spoilage. To this end, the cups are provided with stacking rings and cylindrical sealing surfaces whereby a certain degree of movement between adjacent telescoped cups is permissible without allowing the entrance of air into the space between such adjacent cups. The inner and outer walls of each cup are spaced apart in the stacking and sealing ring area to allow pivotal movement of an inner cup wall with regard to its corresponding outer cup wall, whereby a telescoped stack of nested cups can flex, i.e., the axis of the stack can go from straight to arcuate, without breaking the seal between adjacent telescope cups which would lead to contamination or spoilage of the food ingredient therein.

Abstract: A thread-forming screw has a work-entering section for forming a thread in a workpiece and a work-holding section adjacent thereto. Both sections are of an arcuate, polygonal lobular configuration in cross-section. The amount of lobulation on the holding section is considerably less than the lobulation on the work-entering section, which is of such magnitude as to insure effective thread-forming at low torque. The lobulation on the holding section is preferably just sufficient to effect a locking action with the thread of the workpiece and also to improve the stripping torque of the screw from the workpiece. The work-entering end of the fastener also has a pilot thread of about one turn and with a uniform width over 360.degree. and sized approximately the same as the pilot hole in the workpiece to prevent cocking of the fastener as it is initially inserted into the pilot hole. Thread-rolling dies for forming the fastener have a die section with grooves of equal depth to roll the pilot thread.

Abstract: In accordance with the present invention an apparatus and process are disclosed wherein coal or peat or lignite is first transmitted to a devolatilizer from which tar and fuel gas are removed for transmission to a separator and recovery system, from which by-products are obtained and sulphur-free fuel gas is transmitted to the steam boiler. Char is recirculated between the devolatilizer and a heat generator. In one form of the invention a fraction of the char discharge from the devolatilizer is transmitted to a gasifier for gasification and complete sulphur extraction, and another fraction in readily combustible form is transmitted to the steam boiler for use. In another form of the invention the complete output of the devolatilizer is transmitted to the gasifier wherein a fraction is gasified and another fraction is transmitted to the steam boiler. The proportion of the fractions may be controlled to thereby control the overall sulphur emission of the system.
