Abstract: A live Salmonella vaccine having an increased stability is disclosed. Further, immunization methods of a host such as chickens against Salmonella diseases are carried out by the use of the vaccine. The vaccine may be administered orally or parenterally and includes one or more of the live vaccines disclosed herein. The live vaccine is produced from one or more live vaccine strains with metabolic drift attenuation via an increased generation time. The vaccine is an immunogenic, stable and single or multiple marker live vaccine strain with or without envelope mutation; and the live vaccine is a suppressor mutant of an original live vaccine strain still having the attenuation marker(s) of the original live vaccine strain but a shortened generation time and having macrolide tolerance.

Abstract: Improvements in devices for receiving, hanging and supporting purses, handbags and other strap carried containers on the edge of a table, desk or other support; portable hanger devices for purses, handbags and the like able to engage the periphery of a table, desk or other support and receive therewithin the straps of a purse or handbag in such a manner as to support it in at least two optional positions, thus enabling free support of the container, handbag or purse in either crowded or open conditions around the table or desk.

Abstract: Containers for receiving, holding and transporting a pair of drummer's cymbals from a hi-hat stand; containers for receiving, holding and transporting large diameter circular, sectionally arcuate objects in pairs such as musical cymbals of identical diameter taken from a hi-hat stand; receiving, containing and carrying containers for two paired, opposed cymbals taken from a hi-hat cymbal stand; containers adapted to receive, hold, contain and protect a pair of opposed, equal diameter cymbals actually mounted on a hi-hat cymbal stand, the containers not only holding and carrying the cymbals therewithin, but also transportable and carryable with the hi-hat stand, per se.

Abstract: A golf club shaft is provided with a training head that, when the club is swung, strikes a movable, upright target composed of a yieldable, light-weight material. The target presents a relatively broad, laterally facing target surface and, when struck, becomes attached to the head and is carried thereby through the remainder of the swing. The addition of the target to the head provides increased resistance to train the player to increase club head speed at impact and beyond. The training head provides visual feedback at the finish so that the player will know whether a proper swing was executed.
