Patent CA-2018207-A1 (CA)
IPC: F04C27/00
Filed: 1990-06-04
Abstract: This invention discloses an axial sealing mechanism for axially sealing an orbiting scroll and a fixed scroll of a scroll type compressor. The com-pressor includes a driving mechanism for driving the orbiting scroll in an orbital motion and a block member fixedly attached to the housing of the scroll compressor to support the driving mechanism. The block member and the fixed scroll define an intermediate chamber in which the orbiting scroll is disposed. The intermediate chamber is divided into a first and second chamber by an end plate of the orbiting scroll. At least one first conduit sized to produce a pressure throttling effect, links the second chamber and the discharge chamber of the compressor to increase the pressure in the intermediate chamber. At least one second conduit, which also is sized to produce a pressure throttling effect, links the second chamber to the suction chamber of the compressor. During operation of the compressor, the second chamber is maintained at an intermediate pressure without pressure fluctua-tion due to the presence of the at least one first and second conduits. This intermediate pressure provides a constant urging force against the orbiting scroll to urge it against the fixed scroll to obtain a good axial seal between both scrolls without decreasing the durability of the driving mechanism and the rotation preventing mechanism or the life of the compressor.

Abstract: A remote control modification (11) for a hydraulic steering system (13) of the type used to steer underground loaders and the like is disclosed. The remote control modification comprises a bidirectional, spring-loaded remote control valve (51) connected in parallel with the bidirectional, spring-loaded control valve (19) that normally responds to steering inputs created by the manual movement of a steering arm (25). The remote control valve (51) has outlet ports (75 and 77) that are smaller than the outlet ports (39 and 41) of the manual control valve (19). Movement of the piston of the remote control valve (51) is controlled by a slave hydraulic actuator (53). The flow of hydraulic fluid to the slave hydraulic actuator (53) is controlled by a solenoid-actuated valve (59).  The solenoid (61) of the solenoid-operated valve (59), in turn, is controlled by a receiver (63) that responds to radio frequency control signals (105) generated by a remotely located transmitter (65). Located in the hydraulic lines between the solenoid-operated valve (59) and the slave hydraulic actuator (53) are restrictor/reverse bypass pressure relief valve combinations (55 and 57).  Finally, preferably, the hydraulic line running to the larger capacity chamber of the slave hydraulic actuator (53), i.e., the non-shaft chamber, is coupled to the hydraulic return tank via a relief line that contains a manually adjustable restrictor valve (67).

Title: Height adjustable plant hanging device
IPC: A47G7/04
Filed: 1990-07-13
Abstract: ABSTRACT         A height adjustable device for suspending a planter  comprises  a  locking  member  adapted to be mounted above the planter,   a handle member and a cable attached at a first end thereof to the planter. The cable passes through the locking member and is wound around a reel biasedly mounted in the handle member with a second end of the cable being attached to the reel.    The cable is partly wound around the reel.    A disengageable brake is provided for the reel.   The locking member comprises a pair of fixed wheels  which  guide  the  cable  therethrough.     The locking  member  further comprises  a  locking  arm pivotally mounted therein and comprising a series of teeth.  The locking arm is biased towards a first one of  the  wheels,   whereby the cable can be secured between the locking arm and the first wheel.  Tension provided in the cable by the handle member forces the locking arm away from the cable thereby releasing the same and allowing free movement thereof through the locking member and thus permitting the planter to be raised and lowered.   To secure the cable between the teeth of  the  locking arm and the first wheel, a sudden  slack  is  provided in  the cable  using  the handle member in order to reduce the forces exerted by the cable on the locking arm in such a way that the  locking  arm  is  urged  towards  the  wheel  to imprison the cable therebetween.   The disengageable brake allows the handle member to be positioned at various  distances  from  the  locking  member  by counterbalancing  the  forces  of  the  biased  reel provided in the handle member.

Title: Polyamines and their preparation
Inventor: FRIEDLI FLOYD E
IPC: C09K23/16
Filed: 1991-01-11
Abstract: ABSTRACT     The present invention is directed to polyamines re-presented by the following general structure:             where R is an organic group, R' is H or CH3, and x=0 -3. Tri, tetra, penta and hexa amines, accordingly, are dis-closed.     The method for making the novel polyamines comprises a multi-step reaction that commences in step (a) with the cyanoethylation of a primary amine, R-NH2, with acryloni-trile under cyanoethylation conditions to form an aminoni-trile of the structure R-NH-CH2-CH2-CN. The aminonitrile in step (b) is methylated by reaction with formic acid and formaldehyde under Leuckart reaction conditions to form a monomethyl aminonitrile of the structure R-N(CH3)-CH2-CH2-CN. The monomethyl aminonitrile then in step (c) is reduced, preferably by hydrogenation under hydrogenation conditions, to form a monomethyl diamine of the structure R-N(CH3)-CH2-CH2-CH2-NH2. The monomethyl diamine then in step (d) is chain extended again by cyanoethylation with acrylonitrile under cyanoethylation conditions to form a monomethyl dia-minonitrile of the structure R-N(CH3)-CH2-CH2-CH2-NH-CH2-CH2-CN. Finally, the monomethyl diaminonitrile in step (e) is reduced, preferably by hydrogenation under hydrogenation conditions to form the novel polyamine. Repeating step (b) results in R' being a methyl group. Repeating steps (d) and (e) extends x up to 4.

Abstract: PRODUCING A COPOLYESTER FROM A LOWER DIALKYL ESTER          OF TEREPHTHALIC ACID, A GLYCOL AND                  A DICARBOXYLIC ACID                 Abstract of the Invention A process for producing a copolyester by copolymerizing the monomers from the ester interchange of a lower dialkyl ester of terephthalic acid and glycol and the direct esterification of a dicarboxylic acid and glycol using a novel catalyst system.  The novel catalyst composition includes from about 20 ppm to about 150 ppm manganese; from about 50 ppm to about 350 ppm lithium; preferably from about 10 ppm to about 70 ppm cobalt: and from about 200 ppm to about 400 ppm antimony, all amounts being based upon the expected yield of the copolyester.  The novel process to make copolyester includes the step of employing an effective catalytic amount of manganese and lithium in an ester interchange reaction where the lower dialkyl ester and glycol produce a first monomer; to the monomer adding a slurry of dicarboxylic acid and glycol and employing an effective catalytic amount of lithium and cobalt in a direct esterification reaction where the dicarboxylic acid and glycol produce a second monomer; and using an effective catalytic amount antimony in a copolycondensation reaction of the monomers.  Using the catalyst system allows for the combination of the ester interchange reaction with the direct esterification reaction to produce a copolyester.
