Patent CA-2616148-A1 (CA)
Inventor: LEONARD WAYNE ARTHUR
IPC: F16K1/32
Filed: 2006-07-28
Abstract: Apparatus (10) for use with a valve (11) to perform a grinding operation on the valve. The valve (11) has a valve body (13) defining a valve seat (19) and a valve member (21) moveable into and out of engagement with the valve seat (19). The valve member (21) comprises a valve disc (25) and a valve stem (23).  The valve (11) also has a bush (29) through which the valve stem (23) extends in threaded engagement therewith whereby relative rotation between the bush (29) and the valve stem (23) causes axial displacement of the valve stem (23) relative to the bush (29). The apparatus (10) comprises a drive transmission means (55) for providing a driving connection to the bush (29) and the valve stem (23). The drive transmission means (55) has first and second modes of operation, wherein in the first mode of operation the drive transmission means causes the bush (29) to rotate with the valve stem (23) such that the valve stem rotates without undergoing axial movement and wherein in the second mode of operation the drive transmission means (55) causes relative rotation between the bush (29) and the valve stem (23) such that the valve stem undergoes axial movement while rotating. The apparatus (10) has means including hand wheel (245) for selectively causing the drive transmission means (55) to operate in either one of the first and second modes of operation during rotation of the valve stem (23).

Inventor: MORONG WILLIAM H
IPC: H03F3/45
Filed: 2006-11-06
Abstract: A power-conversion regulator comprising an inductive reactor, an output filter reactor, and a switch for admitting energy to the inductive reactor, additionally comprises computation circuitry responsive to the flux in the inductive reactor, to a reference signal, to an output voltage, and sometimes to an output load current, for computing the quantity of energy that must be supplied to a load and to the output filter reactor to regulate the output voltage or current to a desired relationship with the reference signal during each chopping waveform cycle driving the switch. As the inductive reactor is charged from an input energy source, the computation circuitry predicts whether the energy in the inductive reactor has become adequate for the regulation.

Patent CA-2651161-A1 (CA)
Title: Magnetron
Inventor: SOBIERADZKI EDWARD STANLEY
IPC: H01J25/58
Filed: 2009-01-22
Abstract: A magnetron has a first set of vanes which connect by legs to a coaxial output coupler and a second set of vanes which (in one example) alternate with the vanes of the first set and are not connected to the output coupler. The vanes of each set are held, for example, by strap rings which may be distributed along the length of the anode, at the same potential as each other, and the polarity of the vanes of one set is opposite to that of the other set. A  problem with such a magnetron is that there is capacitive coupling between the cathode and the output coupler, which can lead to the coaxial TEM mode propagating along the cathode. According to the invention, additional capacitive coupling is introduced by means of axial extensions on the ends of the set of vanes which are not connected to the output coupler, and by choice of dimensions, the cathode is substantially decoupled from the output coupler because of the opposite polarity of the two sets of vanes.

Title: Process for preparing 2,3-dimethylbutane and uses of the resulting product
Inventor: BASSET JEAN-MARIE
IPC: C07C9/16
Filed: 2007-06-12
Abstract: The present invention relates to a process for preparing 2,3-dimethylbutane which comprises contacting in a reaction zone isobutane with a supported catalyst comprising a tungsten hydride and a support comprising an aluminium oxide, so as to form a reaction mixture comprising 2,3-dimethylbutane. The contacting essentially leads to performing a metathesis reaction of the isobutane, with a very high specificity in the formation of 2,3- dimethylbutane. The catalyst is preferably a tungsten hydride grafted onto a support based on aluminium oxide. The support can be chosen from aluminium oxides, mixed aluminium oxides and modified aluminium oxides. The reaction mixture can be isolated and preferably subjected to one or more fractionating operations in order to recover 2,3- dimethylbutane and optionally one or more other components of the reaction mixture, such as C5+ alkanes. The process can comprise isolating from the reaction mixture the C5+ alkanes including 2,3-dimethylbutane as a single component, which can be blended with gasoline to enhance the gasoline octane number, or be used as a gasoline blendstock. At least one separated fraction containing 2,3-dimethylbutane can be isolated from the single component, which can be blended with gasoline to enhance the gasoline octane number, or be used as a gasoline blendstock.
