Patent CA-2081325-A1 (CA)
Title: Flux control techniques for magnetic bearing
Inventor: HARRIS TIMOTHY A
IPC: F16C39/06
Filed: 1991-03-07
Abstract: FLUX CONTROL TECHNIQUES FOR MAGNETIC BEARING                  Abstract of the Disclosure A magnetic bearing has a number of pole pieces disposed about the circumference of the shaft supported by the bearing. To inhibit magnetic flux migration within the bearing, magnetic barriers of non-magnetic material are interposed between pole pieces at selected locations.  The magnetic guides prevent magnetic saturation of the bridging portion of the pole pieces prior to the poles saturating.     The invention may suitably be employed to improve the operation of magnetic bearings.  Magnetic bearings are used, for example, in rotating electrical machines such as compressors.

IPC: B65B5/06
Filed: 1991-05-10
Abstract: Apparatus and process in which one plate, or several ac-curately superimposed plates (10, 16) carry items (12, 18) to be packaged. On inversion of the plates, items either fall directly in-to the voids of a partitioned box (26) or fall into individual pack-ages held by a plate, which packaged items are then ejected by pushrods, etc. into a single box. A plate may have cut-away por-tions (e.g. V-shaped grooves) which receive upstanding edges or partition walls of a box to accurately register box with plate (and contents) and nest the box into the plate to achieve configura-tion-accurate inversion of the items to be packaged.

Title: Pipe ring crimping tool
Inventor: CLELAND JOHN G
IPC: B25B27/14
Filed: 1992-12-24
Abstract: A pipe ring crimping tool providing significant mechanical advantage for applying force with a sufficient jaw opening and minimal external dimensions, minimal handle span and minimal handle length throughout the operational cycle. The tool is compact and lightweight to allow reach and access of the jaws into confined spaces. The tool utilizes a link and pin mechanism to translate the operator hand force in a manner which allows for smooth application of operator hand force while increasing the crimping force as the pipe ring is compressed. The tool configuration, by minimizing the handle spread, allows for single-handed operation of the tool or closely held two-handed operation. The tool includes a link mechanism designed to provide smooth crimping force and to preclude tool locking up and excess friction. The handles move laterally in opening the jaws to their maximum spread and are closed rotationally when crimping the pipe ring.

Patent CA-2087304-A1 (CA)
Inventor: JOHNSTON DAVID E
IPC: F16J15/3244
Filed: 1993-01-14
Abstract: An annular radial seal has a sealing axis and a sealing lip of polymeric material for the engagement of the circumference of a shaft to be sealed. The sealing lip has circumferentially evenly distributed radially protruding ribs and is radially inwardly defined by a frustoconical inner surface, the diameter of which increases away from the space to be sealed. At that side of the sealing lip remote from the sealed space the inner surface defines a first angle with the sealing axis direction, which is 0.02 to 0.5 times as large the magnitude of a second angle defined by the inner surface and the sealing axis direction at the side of the sealing lip adjacent the sealed space. The ribs are formed by an undulation of the inner surface which extends only in circumferential direction along a circumferential line. The seal has excellent operating characteristics over a long service period, provides improved sealing results and reliably prevents leakage of the liquid present in the space to be sealed whether the shaft is stationary or rotating and independently of the direction of rotation of the shaft.

Title: Switchable dual mode directional filter system
Inventor: KICH ROLF
IPC: H01P1/213
Filed: 1993-01-22
Abstract: ABSTRACT       A switchable dual mode directional filter system (10) includes two identical filters (16, 18) coupled to input and output waveguides (12, 14) at the same plane in phase quadrature. Each waveguide has two ports (34, 36, 38, 40) through which the signal enters and exists. One of the filters has a switching device (42) incorporated therein for selecting the desired output port. One embodiment of the switching device includes a pair of coupling members (48, 50) that extend radially inward within the cavity of the filter toward a central axis. These coupling members define two coupling positions for the system. Solenoids (44, 46) move the two coupling members into and out of the cavity of the filters. Only one coupling member is used at a given time. This switching device is designed to change the polarity of one of the components of the signalwave to change its wave characteristics in the output waveguide. As a result, the desired port of the output waveguide can be selected easily.

Abstract: The invention relates to a process for the exploitation of oil shales wherein the two main contituents threreof, organic and inorganic moieties, are transformed into valuable products, It was found that oil shales which possess a high amount of inorganic constituents, as well as than mineral part resulted from the combustion of oil shales, have a catalytic effect on the cracking of ~ heavy fraction of fuel, producing valuable fractions of hydrocarbon fuel. According to the process, a mixture of oil shales which possess a low portion of organic moiety, is cracked at a temperature in the range of 350 to 600°C with a fraction of heavy fuel having a boiling point of above 350°C. From the gases going out from the cracking reactor, a hydrocarbon fuel having a boiling point of up to 350°C is recovered. The residue resulted in said crac-king is useful as a raw material in the chemical industry.
