Abstract: Portable association croquet wicket practice assembly of three-point playing surface contact, defining a simulated target wicket wherein upright legs are fixedly spaced apart in regulation measure by a topmost transverse crown, the free ends of the legs being supported by surface contact, the target wicket being ballasted and balanced rearwardly by two interconnected weights, a first weight being elevated and fixed relative to the crown to apply vertical and horizontal moments to the wicket, a second weight being in slope declination relative to the first weight to apply target aligned and anchoring moments to the wicket. The wicket, per se, is white in the assembly foreground and neutral or dark in its background.

Abstract: A portable and collapsible hand tool is disclosed wherein successive small samples of suspected contaminated earth soil may be directly deposited in a sampler bottle, following selective penetrations and extractions of the soil. The sampler is characterized by a substantial balanced mass which is vertically disposed above the sampler tool head, the head having in extension thereof a soil probe column which forms a tube of reverse draft, the same being interconnected to an inverted sampler bottle which is retained within the head where it is shock protected.

Abstract: A yarn delivery device is provided for textile machines, particularly for air jet looms. A knotcatcher is provided with a measuring drum that reduces frictional drag on the yarn thus reducing the air requirements for pulling the yarn off the drum, reduces the wear on the yarn contact points, has longer life, and is easier to repair than conventional knotcatchers. The knotcatcher includes a circular plate having a circular axially upstanding circular rim, with a plurality of smooth-surfaced hardened steel cylindrical pins upstanding from the rim. The pins are press fit into holes formed in the rim, and if damaged may be readily replaced.
