Patent CA-2041082-A1 (CA)
Title: Apparatus and method of water culture and plant handling method
Inventor: KOIDE KOSHI
IPC: A01G9/02
Filed: 1991-04-24
Abstract: ABSTRACT OF THE DISCLOSURE A water culture apparatus wherein air space sections are  formed  between  plant  containers  and  a  nutrient solution when rafts are floated in a water culture tank filled with the nutrient solution.  The plant containers are inserted in vertically oriented channels provided in the raft.  The air space sections are formed in order that the plant containers do not get submerged in the nutrient solution.  The plants are cultivated by: gradually moving the raft from one end to another end of the water culture tank, movement of the raft corresponding to a state of growth of the plants so that the plants supported by the plant  containers  reach the  other end by the time the plants have grown as a result of having absorbed nutrients from the nutrient solution; and harvesting the plants when each of  the rafts reaches  the other end of the water culture tank.  The plants are handled by: sowing several seeds into each of the plant containers, the seeds in each of  the plant  containers  corresponding  in number  to  a shipping  unit  of  the  plants;  and preparing  the  plant containers along with the plants  contained therein  for shipping once the plants have grown.

Title: Oxidation-resistant cation-exchange resins
Inventor: DHINGRA YOG R
IPC: C08F212/34
Filed: 1992-03-06
Abstract: ABSTRACT       Cation-exchange resins are provided which have improved resistance to copolymer degradation caused by oxidizing agents like molecular oxygen.  The resins are prepared by functionalizing a plurality of certain cross-linked copolymer beads with cation-exchange groups.  The cross-linked copolymer beads are prepared from a para-substituted monovinyl aromatic monomer comprising an aromatic ring substituted with an oxidation-stabilizing moiety in a position para to a polymerizable vinyl moiety.  The oxidation-stabilizing moiety is substantially inert during substitution of the copolymer beads with the cation-exchange functional groups, which avoids substitution at the para position. Exemplary of such para-substituted monovinyl aromatic monomers are para-methylstyrene, para-ethylstyrene, and para-chlorostyrene.  The cation-exchange resins are capable of being used in a separation process for longer periods of time without detrimental increases in bed pressure drops, loss of operating capacity, and leaching of organic contaminants.     37,528-F

Inventor: KAWADA MASAKI
IPC: B23K11/31
Filed: 1992-03-10
Abstract: In a DC type C-shaped welding gun apparatus having a transformer mounted thereon, a center tap of the transformer is communicated to a movable gun arm via an ounce metal plate.  A rear end portion of a stationary gun arm is pressingly held between a pair of terminal plates via rectifiers.  Both terminal plates are disposed such that their center line is offset to one widthwise side of the transformer.  The stationary gun arm is thus disposed to one widthwise side of a projected area of the transformer.  The ounce metal plate for supplying electric power to the movable gun arm is disposed to the other side of the projected area.          In an X-shaped welding gun apparatus, a first gun arm is rotatably supported by a supporting shaft provided on a gun bracket.  A second gun arm is directly connected to one of feeder terminals of a transformer to constitute the second gun arm and the transformer into a unit.  This unit is rotatably supported by the supporting shaft via a supporting arm, and the other of the feeder terminals is connected to the first gun arm via the supporting arm.  The supporting arm is used as a feeder member.  The feeder member can thus be disposed within the width of the gun bracket.  A pressurizing cylinder is supported on the supporting arm along the transformer.  The vacant space around the transformer is utilized as a space for disposing the cylinder to thereby minimize the size of the welding gun.

Abstract: A nut for use in a bolt assembly having an adhesive anchoring capsule for attaching roof or wall supports to the rock structure of a mine. The nut has deformities in its continuous internal thread that cause the continuous internal thread to bulge inwardly toward the axis of the bore. The deformities limit the advance of the nut upon a bolt and are formed by stamping dimples into one face of the nut. When an overcoming torque is applied, the deformities in the continuous internal thread are pushed radially outwardly and the nut is allowed to further advance upon the bolt. Because the deformities do not form a break in the thread, which remains continuous, no fragments are formed to damage the bolting tool, and the bolt thread remains undamaged so that a second nut can be threaded on it to hold a screen or the like.
