Abstract: A pad (16) of open celled fully reticulated polyurethane foam which is substantially hydrophobic serves as a bed for growing sprouts (14) from seeds (12). A high percentage of interconnected voids in the pad (16) provide a high degree of permeability to air flow and the material has surface properties, which retain adhered droplets of moisture providing humid environment without holding localized moisture which might prevent the free flow of air through the pad. The bulk of any applied water or mist is drained through or away from the pad, thus flushing impurities from it. A loose cover sheet of film (15) helps retain a humid atmosphere and pad (16) may be wrapped in such a sheet (18) to package the sprouts (14). The pad (16) may be transferred to a shipping tray (34) after the seeds are sprouted or may be originally placed in it. The pad (16) and tray (34) may have an extended lip (38) for collecting moisture when the package is inclined on end to provide optimum conditions during storage.

The seeds are uniformly spread across the bottom of the container with the aid of an upwardly directed light source. The bottom of the container is porous and a flow of air maintained through it during sprouting. The sprouts are entangled by growing in a porous hydrophobic foam or tilting the bottom of the container to several angles for the sprouts to mature. After maturing, the entangled sprouts are dumped from the container and wrapped under tension to provide a strong compact resilient package in a wrapper sheet which is folded over itself and sealed by heat sealing, twisting or crimping.

Abstract: An improved grinding method and apparatus is advantageously used to sequentially grind the pins of a crankshaft. During the grinding of each crankpin, the pin is supported by a steadyrest. During an initial grinding operation, the crankpins are measured or gauged to determine if they are out-of-round by an amount which is greater than the tolerances for the finished crankshaft and less than a maximum amount. If a crankpin is out-of-round by an amount which is equal to or greater than a maximum amount, the crankshaft is rejected. However, if a crankpin is out-of-round by an amount which is less than the maximum amount and more than the tolerance for a finished pin, a second grinding operation is initiated after the initial grinding operation has been completed. During the initial and second grinding operations, a main drive motor is effective to press the steadyrest against the crankpins.

Abstract: A strand break-out device for preventing the formation of the fault yarns due to strand breakage when two unspun fibrous strands are spun on a common twisting spindle. A member (24) has pins (38) forming a passage means to which the strands converge during travel to the spindle and on which the strands may bear to apply force to the member. The member is pivotally mounted on a support (28) so that it may move freely on the support between limits of displacement from a mean, stable disposition.
