Patent CA-2036064-A1 (CA)
IPC: B65G33/18
Filed: 1991-02-11
Abstract: ABSTRACT OF THE DISCLOSURE TELESCOPIC AUGER           A telescopic auger includes a first drive tube and a second drive member coaxial with the drive tube and slidable inside the drive tube in telescopic manner.   A flight is attached to the drive tube in helical arrangement.  A second flight section is-attached to the drive member at an outer end only of the drive member with the second flight being threaded into the end of the first flight so that rotation of one relative  to  the  other  causes  the  length  of  the  threaded engagement to increase or decrease to allow telescopic adjust-ment of the length of the total auger flight.  This arrange-ment can be used in a bin sweep which allows the sweep to be adjusted in length to accommodate bins of different diameter. The sweep section is driven across the ground by a drive track at an outer end of the auger section.   The auger section is coupled to a main auger section which extends from the centre Or the bin outwardly to the exterior of the bin by a flexible or rotary joint which allows the  sweep section to rotate through 360° during operation.   The rotary joint is provided by a flexible auger core to which is attached a plurality of separate collars each carrying a helical flight section.  The total drive for the system can therefore be provided by a motor at an outer end of the main auger section.

Title: Automatic transfer switch
Inventor: CASTENSCHIOLD RENE
IPC: H01H71/00
Filed: 1991-03-18
Abstract: AUTOMATIC TRANSFER SWITCH An automatic transfer switch having two sets of phase switches, one set for connection between a normal source of power and a load, and the other set for connection between an emergency power source and the load. The transfer switch also includes two pairs of neutral switches, one pair for connection in parallel between the normal source neutral and the load neutral, and the other pair for connection in parallel between the emergency source neutral and the load neutral. The phase switches can operate to provide an "open transition" transfer, wherein the phase switches connecting the load to one source open before closing of the phase switches which connect the load to the other source, or a "closed transition" transfer, wherein the phase switches connecting the load to one source open after closing of the phase switches which connect the load to the other source. Prior to a transfer operation, the pair of neutral switches corresponding to the closed set of phase switches are closed and the pair of neutral switches corresponding to the open set of phase switches are open. During transfer of the load, whether by open transition or closed transition transfer, one neutral switch of each pair are closed before the open set of phase switches close and those neutral switches remain closed until after the closed set of phase switches opens. Thereafter, the pair of neutral switches which had originally been open are both closed, and the pair of neutral switches which had originally been closed are both opened.

Abstract: Part of a melt vessel is formed from a porous member which is permeable to gas and impermeable to melts.  Alternatively, a bottomed cylindrical partitioning member immersed in a melt in the melt vessel, or part of a circulating vessel through which the melt circulates, or a dam disposed in the course of circulation of the melt in the melt circulating vessel is formed from the porous member.    Vacuum pump is used to suck gas from the melt or gas produced by a reaction at the interface between the melt and the porous member through the porous member, to the side of that surface of the porous member which is not in contact with the melt and kept at a vacuum or at reduced pressure.    Then, the pressure at the interface between the melt and the porous member is lowered, and a space which is in a vacuum or at reduced pressure can be easily created in the melt.  Thus, solute ingredients of the melt nucleate easily to form gaseous substances, so that the gaseous substances are sucked into said space and removed from the melt.
