Abstract: ABSTRACT OF THE DISCLOSURE      There is provided a shearing machine in which the ram can be accurately and smoothly moved up and down with a simple arrangement without need of troublesome adjustment.          The shearing machine is so arranged that the ram, when vertically moved, is resiliently guided by spring means and is driven by driving means in such a manner as to be kept urged into contact with the guide means.  The shearing machine also has hold-down means which can firmly hold the work-sheet being sheared without producing large noises and damaging the work-sheet.  To attain this a hydraulic pump means for the hold-down means is provided with a large diameter piston which will supply a large amount of flow under low pressure and damp the surge and a small diameter piston which will supply a small amount of flow under high pressure.  The shearing machine also can perform shearing operations to produce fine workpieces without bending and curling.  For this purpose, the shearing machine is provided with hold-up means which will upwardly hold the work-sheet being sheared to prevent the work-sheet from bending and curling.  The shearing machine also has a back guage means which can be used to set the widths or lengths into which the work-sheet is to be sheared but which can be moved out of the way to enable a work-sheet to be sheared into a different size.

Abstract: ABSTRACT OF THE DISCLOSURE                  The present invention relates to a process for drying coated workpieces, particularly workpieces of irregular shape, by infrared radiation and to an apparatus for carrying out this process.  The present invention can be used for drying castings, particularly those having an irregular shape, thin-walled sheet-metal products as well as ceramic and glass products which have been coated with a powder or an electro-dipping varnish or water-soluble or solvent-containing varnishes. According to said pro-cess the workpieces are dried by infrared radiation in several zones at a specific temperature, an air flow being provided in the zones and the air being drawn off from one zone.  According to the present invention the workpieces are preheated in the first preheating zone.  In the second rest zone the infrared radiation is interrupted so that the temperature of the workpieces slightly decreases.  In the third reheating zone the workpieces are completely dried by subjecting them once more to infrared radiation while the air is circulated and heat is addi-tionally supplied to the workpieces by convection.  The apparatus comprises a casing, wherein infrared emitters having reflectors are disposed in several zones at intervals from the casing walls, the emitters encompassing an irradiation space.  The apparatus also has inlet and outlet openings and a means for conveying the workpieces through the casing and a suction device.  According to the present invention a rest zone without any infrared emitters is disposed between a preheating zone and a reheating zone.  The suction device in the rest zone is so disposed that the air is circulated within the casing.

Abstract: EXPANDABLE PRESSURIZED BARRIER CONTAINER     ABSTRACT OF THE DISCLOSURE        A pressurized thin walled expandable can from which a fluent pressurized product is dispensed is made from an expandable can wall and a barrier, which may be a fully evertable bag having uniform thickness and flexi-bility and shaped to fit within the can wall.  The open end of the bag is mounted to the can wall by means which maintain a seal as the can wall expands and returns to its unexpanded condition.  As product to be dispensed is introduced into the product chamber, the flexible bag is extended down into the lower end of the can.  As the pro-duct is later expelled through a discharge opening, the flexible bag, which may be plastic, is fully everted into the upper end of the can to expel all the product.  The can is thin walled, so that when pressurized, the can di-ameter expands by at least one-thousandth (1/1000) of its unexpanded value.  In one embodiment, the bag is mount-ed by a ring inside the can.  The ring includes a portion which expands to maintain the seal with the expanding can side wall.  In another embodiment the ring is rigid, but of slightly larger diameter than the can.  This ring stretches the can, so as to maintain the sealing contact with the can as the can expands.  In other embodiments, the bag may be mounted by a stretchable adhesive and, if the bag is slightly elastic, it may be mounted by an ad-hesive or by a melt seal process such as heat sealing.

The caches are coupled to the system bus as well as to the micro-processor.   A  primary main memory  is  coupled  to  the system bus for selectively storing and outputting digital information.  The instruction and data caches are coupled to the primary memory via the system bus for indepen-dently and selectively managing and accessing the primary memory  for  selectively  storing  and  outputting  digital information to respective mapped addressable very high-speed cache memory.  The system bus provides a high-speed bus coupled to the primary memory, instruction cache, and data cache, and other system elements, for communicating the information therebetween at a high rate.  The micro-processor is coupled via separate and independent very high-speed  instruction  and  data  buses  to  each of  the instruction  cache  and  data  cache,  respectively,  for processing data received from the data cache responsive to instructions received from the instruction cache.  The instruction bus and data bus are exclusive and indepen-dent of one another.  This provides for very high speed instruction transfer from the instruction cache to the microprocessor via the  instruction  bus  and allows for simultaneous very high-speed transfer of data between the data cache and the microprocessor via the data bus.  The data  cache  and  instruction  cache  each  have  separate dedicated system bus interfaces for coupling to the main memory and to other peripheral devices which are coupled to the system bus.   Numerous other system elements can also be coupled to the system bus, including an interrupt controller,  an I/O processor,  a bus arbiter,  an array processor, and other peripheral controller devices.
