Title: Process for growing sprouts
Inventor: STEWART WILLIAM F
IPC: A01G31/02
Filed: 1979-10-11
Granted: 1981-09-15
Abstract: Abstract Process for growing sprouts from seeds comprises circulating the water in which the seeds are germinated continuously for 8 hours so that the seeds are continually germinating in fresh water.  The germinated sprouts are then repeatedly allowed to drain and stand fox approximately 4 - 8 hours and then soaked for approximately 15 minutes.  For the first 48 hours the sprouts are lightly worked during the soakings by being separated by the user's fingers.  Between 48 and 72 hours the sprouts are heavily worked and are submerged during the soaking cycle, and the floating husks are removed from the container in which the sprouts are soaked by skimming the container while the sprouts are sub-merged.  Between 72 and 144 hours, in addition to the skimming, after each soaking the sprouts are removed from the container and the container cleaned.  Also after 72 hours and 96 hours the sprouts in each container are split in approximately equal portions and each of the portions are placed in separate containers.  Therefore, the sprouts germinated in a single container ultimately fills four containers by the time the sprouts are ready for harvesting so that the depth of the sprouts growing in a container remains relatively constant.

Abstract: ABSTRACT OF THE DISCLOSURE           An injection-molding machine has a fixed and a movable outer platen bracketing amovable intermediate platen, the latter having a runner system conducted via an extensible or flexible conduit to a source of molten plastic material to be injected into cavities defined by respective pairs of mold portions supported by the three platens, the cavities being formed in part by cores carried on the outer mold portions.  A stripper plate inserted between each pair of mold portions is articulated via a spring-loaded lost-motion link to a respective eccentric pin on a pinion which is rotatably mounted on the intermediate platen and meshes with a pair of racks respectively secured to the two outer platens; this linkage is duplicated on opposite sides of the mold.  In an initial phase of a mold-opening stroke, the stripper plates move outwardly under spring pressure while remaining in contact with their respective outer mold portions whose cores still retain the freshly molded articles.  When the limit of the lost-motion travel is reached, the stripper plates are slowly lifted off their adjoining mold portions to detach the molded articles from the cores.
