Filed: 1997-12-29
Abstract: Biologically active O-substituted azabicyclo oximes having the Z configuration may be isolated simply, without chromatographic separation, and in high yield and Z/E purity through the coupling of a 1-azabicyclo-3-one with an Osubstituted hydroxylamine in acidic aqueous solution and conversion of Econfigured isomer to Z-isomer without requiring purification or separation. Neutralization and subsequent isolation of the free base followed by precipitation of the salt allows separation of the Z-isomer with high Z/E purity.
Patent CA-2271403-A1 (CA)
Inventor: GOCEVSKI VLADIMIR
IPC: E04C3/04
Filed: 1999-04-22
Abstract: A bolted metal joist (in general made out of structural steel and than called steel joists) is a light truss-girder that is resisting solicited bending moments and shear forces by appropriately designed top and bottom cords and web (diagonals and verticals) members. It is assembled with prefabricated members in a shop or at site. The main characteristic separating the proposed steel joist from the steel joists used today is that the elements instead of being welded between themselves at the nodes are connected by bolting. Another distinct characteristic separating the bolted steel joists from the other bolted truss-beams, truss-girders or truss-columns is that at the nodes the elements are connected with a single bolt instead of multitudes of bolts or rivets. The bolted steel joist comprises a pair of horizontal elongated chord members having a "hat" type cross-section for short and intermediate spans (Fig's. l and 2) or two buck to buck angles for relatively long spans (Fig.3). The chord members have bolt-holes through the flat bottom. The holes are spaced along their length. The joist's web comprises of diagonals in tension and verticals in compression or diagonals in tension and diagonals in compression connected to the top and bottom chords. The bolts extend trough the registering holes (single bolt per connection) to secure the chords and truss's web members together. The steel joist may support concrete floor. In such a situation the joist may be designed to have composite action with the concrete slab in resisting the loads. The top chord bolts extend trough the registering holes into the concrete slab and act as studs. The top chord of the joists in the case of concrete slab is positioned to accommodate steel deck serving as a form during the poring of the concrete mix.

Abstract: A lightweight aerosol dispenser enclosing a first component of an explosive nature is filled at a factory.      A second component is supplied in a smaller container, separate from the dispenser, containing a predetermined amount of propellant. By providing separate containers for each of the explosive and propellant components, both components retain their classification as a flammable substance for transportation and storage purposes.       However, in the field, the propellant is injected into the solution container immediately before use. Only after the two substance components have been mixed can an explosive composition be produced. If, for any reason, the explosive composition comprising a foam is not used, it can be washed away with water or will dissipate itself within a few hours.

IPC: H01P7/06
Filed: 1999-10-19
Abstract: A ceramic resonator element having high Q, high dielectric constant, and a low temperature coefficient of resonant frequent:y is enclosed within a cavity to form a composite microwave resonator having reduced dimensions and weight as compared to a simple cavity resonator. In an exemplary embodiment, a pair of tuning screws extend into the cavity along orthogonal axes to tune: the structure to resonance along these axes at frequencies near the fundamental resonance of the ceramic element. Several such cavities can be formed in a short length of waveguide by the use of transverse partitions at spaced intervals and coupling between cavities can be accomplished by using simple slot, cross or circular irises. In each cavity, a mode-perturbing screw is positioned along an axis 45° from each of the orthogonal tuning screws, such that resonance along either of the orthogonal axes is coupled to excite resonance also along the other. The input and output coupling devices are disposed at locations that are angularly separated from the corresponding tuning devices by a selectable angle that varies between 0 degrees and ~180 degrees. This variability in location of the input and output coupling devices provides for a filter having adjustable input/output coupling. The realization of complex filter functions requiring cross couplings is feasible by means of coupling separately to only one of the two orthogonal resonant-modes in the cavities.

Title: Mecanisme de butee d'arret
Inventor: LEVESQUE MARIO M L
IPC: E01H5/04
Filed: 1999-11-18
Abstract: Pour toute souffleuse à neige à tambour rotatif, il y a un risque de déplacement du tambour rotatif, malgré que l'on ait bloqué celui-ci à la position voulue. Le tambour rotatif reçoit des chocs lorsque la neige s'entasse dans le fond du tambour et que l'éventail tourne, ce qui crée une pression sur le tambour qui se déplace sous l'effet de la neige. Aussi, un cylindre hydraulique peut avoir une fuite ce qui empêcherait un mécanisme hydraulique de faire le travail de retenue de tambour rotatif. Dans la présente invention, le mécanisme de butée d'arrêt qui est fixée près du tambour insère un pointeau dans une butée fixée au tambour. Ce qui bloque le tambour rotatif à l'endroit voulu sans aucune possibilité de déplacement par choc, par neige ou par fuite hydraulique. La seule façon de pouvoir déplacer a nouveau le tambour rotatif c'est par l'opérateur de la souffleuse à neige tel que souhaité.
