Appl. No.:

09/658871

Inventors:

Richard D. Schlude - York PA
Daniel L. DeMarco - York PA

Assignee:

FKI Industries Inc. - Fairfield CT

International Classification:

G05G 506

US Classification:

74527, 74528, 74545, 464 32, 464 34, 464 38, 254352

Abstract:

An overload protection device for a manual hoist lever including a pressure hub, an outer hub, a brake nut, and a dowel pin. The pressure hub includes a radially extending flange and a cantilevered boss having a threaded outer surface with an axial groove. The outer hub includes a central opening, a tapered inner surface, and a flange contact surface which frictionally contacts the radially extending flange of the pressure hub. The brake nut is disposed in the central opening of the outer hub between the outer hub and the boss of the pressure hub, and includes a frusto-conical outer surface that frictionally contacts the tapered inner surface of the outer hub, as well as a threaded inner opening with a corresponding axial groove, the threaded inner opening being sized to threadingly engage the boss. The dowel pin is received within a receiving hole formed upon alignment of the axial groove of the boss and the corresponding axial groove of the brake nut. The outer hub preferably includes a plurality of ratchet gear teeth and the frictional resistance of the overload protection device adjustable by tightening or loosening the brake nut.

International Classification:

C12Q 1/68

US Classification:

536 2432

Abstract:

This invention relates to a rapid method for detection and characterization of STEC bacteria based on the presence of nucleic acid sequences, in particular, to a PCR-based method for detection, and to oligonucleotide molecules and reagents and kits useful therefore. This method is preferably employed to detect STEC bacteria in a food or water sample, such as a beef enrichment. The present invention further relates to isolated polynucleotides, replication compositions, kits, and reagent tablets for carrying out the method of the present invention.
