Patent CA-1112541-A (CA)
Inventor: CONNOLLY JOSEPH R
IPC: F16K47/08
Filed: 1979-04-24
Granted: 1981-11-17
Abstract: APPLICATION OF:  JOSEPH R. CONNOLLY               FOR:  ADJUSTABLE FLOW CONTROL                      A B S T R A C T           An adjustable flow control valve having a rectan-gular flow control member selectively positionable within a fluid passageway.  The flow control member is mounted trans-versely to the flow passageway in a guide slot integrally formed in the valve housing with the longitudinal edges of the control member extending outwardly from the slot.  A closed end cylindrical adjustment nut having a tubular por-tion surrounding one end of the mounted control member is guided for rotation in a housing bore.  The internal diam-eter of the adjustment nut is threaded and engages corres-ponding external threads located on the longitudinal edges of the rectangular flow control member.  Selective rotation of the adjustment nut is effective for positioning the flow control member into the fluid passageway transversely to the direction of fluid flow therethrough, thereby varying the effective fluid flow area.  The adjustment nut is fluidly sealed to the valve by a seal ring provided between the outer diameter of the adjustment nut and the guide bore in the valve housing.

Abstract: IN THE CANADIAN PATENT OFFICE                   Application for Patent and Offer of Disclosure for Public Dissemination Inventor:  Robert M. Stepanek Owner:     Pettibone Corppration Title:     CAPS FOR HAMMERMILL ROTORS SECURED BY NON-PROTRUDING            INDIVIDUALLY-REMOVABIE PIN ASSEMBLIES     ABSTRACT OF DISCLOSURE Leading edges of rotor plates which carry the swing hammers of hammermills are protected from wear by removable caps, each secured by paired-pin assemblies.  Each pin assembly includes a pair of tubular pins which may be axially abutting one another. During rotor operation, each pin assembly is reliably secure in a pinning position without protrusion into the space between the caps in which the hammers swing.  For removal of a cap, the paired pins may be separated, and each part maneuvered to permit the cap  to be slipped off, without removal of the rotor or its rotor plates. In the illustrated form, the two pins are secured together by a tie bolt through them and countersunk into the pins; and the pins have heads on one end countersunk into the side wall of the cap.

Granted: 1985-03-26
Abstract: Pour traiter des organismes vivants ou des produits biologiques provenant de ceux-ci, on utilise un flux magnétique "modifie" par traversée d'une épaisseur d'une substance non-magnétique à structure cristalline orientée, telle qu'un verre polaroïde ou un métal fortement laminé. Le flux d'un électro-aimant traverse le dispositif interposé (p. ex. un verre polaroïde). Après cette "modification" il ne peut plus traverser ni l'embout métallique ni la gaine métallique; il est donc canalisé par le cordon central fait en fibres naturelles et il arrive à la sonde faite d'un tube métallique terminé par une pointe en bois. Sur le trajet du câble l'on peut interposer des électrodes ou des solénoîdes pour agir sur le flux modifié.
