Patent number: 4015832Abstract: A plasticating extruder screw is provided with a wave section in which the depth of the material conveying channel varies cyclically over a plurality of cycles. The wave section as a whole provides good pumping performance for metering the extrudate at a uniform rate. The deep valley portions of the wave section minimize heat inputs to the material being fed, and the shallow ridge portions of the wave section assure repeated intensive mixing of the material for providing high quality polymer melts. The minimum channel depth portions are in a balanced relationship about the axis of the screw to avoid lateral thrust problems. Such balance may be achieved in successive cycles of a single channel or as between adjacent channels of a multiple channel screw. The wave may be in the metering section of a single stage screw or in any of the pumping sections of a multiple stage screw.Type: GrantFiled: January 31, 1975Date of Patent: April 5, 1977Assignee: Koehring CompanyInventor: George A.

Patent number: 4006677Abstract: A machine for repitting peach halves which have previously been subjected to a pitting operation, but wherein the peach halves are not completely pitted because of split or fragmented pits remaining attached to the fruit. The machine automatically feeds the peach halves, centers them relative to a pitting knife, and re-pits the halves to remove any pit fragments which have escaped the initial pitting operation. Since the initial pitting is done by first cutting whole peaches in half along their entire planes and the resulting peach halves cannot be repitted in the same machine, the present peach repitting machine provides a recovery system for the primary pitting operation in order to increase the overall yield without hand-pitting.Type: GrantFiled: June 23, 1975Date of Patent: February 8, 1977Assignee: FMC CorporationInventor: Leslie Vadas

Patent number: 3989228Abstract: A static mixing chamber for mixing multi-component compositions has the provision of having the mixing chamber at the outlet of the feed lines. A valve is at the outlet end of the chamber. By having the chamber near the outlet end, a large pressure drop across the chamber is insured. Moreover, the valve at the end of the chamber insures that the large pressure drop will be maintained even during start-up of dispensing. By increasing the pressure drop over the chamber, mixing therethrough has been greatly enhanced. Therefore, a smaller mixture is required for effective mixing. The result in small size makes the static mixer capable of being hand held, in the form of a dispensing gun and the valve actuator is part of the dispensing gun so that the valve can be operated by the same hand that is holding the gun.Type: GrantFiled: August 26, 1975Date of Patent: November 2, 1976Assignee: Products Research & Chemical CorporationInventors: Lester Morris, Dennis Perkins

Patent number: 3989230Abstract: A plurality of spaced and parallel auger assemblies are supported in cantilever fashion and extend rearwardly from a bearing housing. These auger assemblies in conjunction with a packing chamber and concrete hopper, extrude a longitudinally apertured slab behind a machine which is moved along rails by the compression and extrusion of the slab. The bearing housing is resiliently supported upon the main frame and is vibrated by one or more vibration generators or motors operatively connected to the bearing housing which in turn transmits the vibration to the individual auger assemblies thus assisting in the flowing and compacting of the concrete being augered by the auger assemblies. This permits auger assemblies of relatively small diameters to be used so that a relatively thin slab can be manufactured by the device.Type: GrantFiled: January 28, 1975Date of Patent: November 2, 1976Assignee: Spiroll Corporation Ltd.Inventor: Ernst Martens
