Patent CA-2015140-A1 (CA)
Inventor: GREENE JAMES L
IPC: H02J7/00
Filed: 1990-04-23
Abstract: Abstract of the Invention A sump pump (86) powered by a rechargeable battery (10) has a circuit for monitoring the battery voltage and con-trolling charging of the battery (10).  Four compara-tors (16-22) monitor the battery (10) and control two flip flops (52, 74) one of which (52) operates the pump in cooperation with a float switch (54) and the other of which (74) turns the battery charging circuit (114, 116 on and off.  The circuitry is arranged so that when the battery (10) is in its discharge cycle, the float switch (54) controls the pump (86) and the charging cir-cuit (114, 116) comes on only when the battery voltage is in a low range.  In the charging cycle, the pump (86) is locked out in a low voltage range of the battery (10) and is controlled by the float switch (54) only in a high vol-tage range.
Patent CA-2015387-A1 (CA)
Title: Ziegler-natta-catalyst component, its preparation and use
Inventor: SORMUNEN PEKKA
IPC: C08F4/60
Filed: 1990-04-25
Abstract: Abstract The invention relates to a procatalyst composition of a catalyst system intended for the polymerization of olefins consisting of magnesium halide particles, to the surface of which has been attached a titanium compound and optionally an electron donor. Moreover, the invention relates to a method for the preparation of the procatalyst composition of this kind and its use. A draw-back in the procatalyst compositions according to the prior art is the disadvantageous morphology of the components, the small amount of the so-called active centers and the sensitivity of the titanium compounds to impurities. These problems have been over-come in the present invention by forming substantially amorphous and spherical magnesium particles, which have been activated with a titanium compound like titanium alcoxide. The magnesium partic-les are prepared by spray-crystallization of the mixture of mag-nesium halide and alcohol and optionally a donor, whereby the produced complex particles after the treatment with an organome-tallic compound are easily and efficiently activated by tita-nium alcoxide which is more durable to impurities.

Title: Ultra-drawn polyethylene fiber reinforced composite material
Inventor: TOKURA KUNIHIKO
IPC: C08G59/14
Filed: 1990-07-12
Abstract: ABSTRACT    The present invention resides in an ultra-drawn polyethylene fiber reinforced composite material having the ultra-drawn polyethylene fibers as the reinforcement material and the epoxy resin as the matrix resin, wherein the epoxy resin is modified with an elastomer to improve adhesivity with the ultra-drawn polyethylene fibers.  Such improvement in adhesivity is ascribable to that low polarity portions are formed in the epoxy resin by introducing the elastomer to raise affinity with ultra-drawn polyethylene fibers, and that the low polarity portions are formed into domains with a specific shape according to types of elastomer employed to effect intercation by a shape effect with the surface micro-structure of the fibers.

Abstract: "MIXING HEAD FOR SOIL TILLAGE"                     ABSTRACT OF THE DISCLOSURE    The mixing head comprises a pair of opposed, spaced apart, generally vertical discs that are generally aligned with the direction of travel, although they are slightly angled so as to be wider apart at their front ends than at their rear ends.  The discs are rotatably mounted to a free floating frame.  Each disc has a plurality of radially extending, elongated, broad, rigid, chisel-like teeth which extend from the disc central portion out beyond its circumferential rim.  The discs are driven to rotate against the direction of travel.  When rotating, the disc and teeth formations operate to cut down into the soil and excavate it in portions carried by the teeth.   The portions are moved inwardly by the angled formations and then thrown  and dropped to  the  rear.  The  furrow  formed  has  a  flat-topped  ridge overtopped with a loose mix of excavated soil and humus.   The furrow is a good growing site for implanted seedlings.
