Patent CA-2075143-A1 (CA)
Title: Process for surface treatment of granules
Inventor: PALCHER FRANK J
IPC: C05G3/20
Filed: 1992-07-31
Abstract: ABSTRACT        A process for surface treating granules, as well as the granule product and surface treatment apparatus thereof.         Granules, such as ammonium sulfate or potassium sulfate for use in commercial fertilizers, are surface coated with a solvent such as water, and then dried to remove excess solvent.  In so doing, the particle surface is slightly softened and then recrystallized in order to enhance its strength.  A gentle agitation means like a slowly rotating, cylindrical drum may be used to allow a predetermined amount of time for recrystallization of the granules, as well as to remove sharp corners of the product.  The solvent may also include a small amount of solid additive such as starch in order to lend time-release and weather resistance properties to the product.

Title: Modular clarifier with integral flocculator
Inventor: SCHMID LAWRENCE A
IPC: C02F3/22
Filed: 1991-02-07
Abstract: A waste treatment module (10) designed for placement within an aeration basin (12) is provided which performs all of the desirable functions of aeration, flocculation, sedimentation, sludge return, effluent collection and skimming. The module (10) includes walls (20) defining an upright chamber (22); the latter is provided with a pair of side marginal, slotted inlets (28, 30) with corresponding flocculators (24, 26) below the respec-tive inlets (28, 30). Each flocculator (24; 26) is equipped with a plurality of vertically spaced baffle plates (86, 88, 90) having offset openings (92, 94, 96, 98) so as to cause solids within the wastewater to traverse a tortuous descending flow path which promotes flocculation. An agglomerated flocculent is collected within a lower sedimentation zone (34) and then passes into a central collector (108) of inverted V-shaped configuration. Suc-tion airlift pumping devices (118, 122) communicating with the collector (108) serve to elevate the flocculent to a trough (120), whereupon the flocculent is returned to basin (12). Clarified li-quid passes through intake pipes (124, 126) and thence into spe-cialized weir devices (132, 134) for discharge to a stream or the like. The module (10) is also equipped with exterior aerators (160), floating skimmers (152) and optional devices (174, 176) for introduction of chemical treating agent into the wastewater adjacent the module inlets (62, 64).

Patent CA-2083089-A1 (CA)
Inventor: YAMAZAKI NOBUO
IPC: F23Q2/16
Filed: 1992-11-17
Abstract: A gas lighter with a safety device has a lock member pivotal between a locked position, where it prevents depression of an ignition, and a released position, where it allows depression of an actuating lever.  The lock member is constantly urged to the locked position by means of a spring.  The lock member has also a finger board extending outside a lighter body and being positioned where it can be depressed with the same finger as is used in depressing the actuating lever, and a stopper being movable between the locked position, in response to movement of the lock member in one direction, and the released position, in response to movement of the lock member in the other direction.  When the lighter is not in use, the lock member is urged to the locked position to make an abutment against an abutment portion on the lighter body, thereby preventing depression of the actuating lever.  When the lighter is in use, depressing the finger board causes pivotal movement of the lock member, thereby resulting in the lock member held in the released position by an engagement of engaging portions.       Dpressing the actuating lever permits the return of the lock member to the initial position.

Title: Seam for fabrics
IPC: D21F1/00
Filed: 1992-02-28
Abstract: Joints for industrial fabrics are made such that the end edge of each part of the fabric is formed with projecting loops (5), which are formed by bending the warp threads of each part backwards, the return parts of these threads being woven into the fa-bric for a given length. The loops of one part are inserted between the loops in the opposite part for being fixed in this position. It is desirable that all warp threads in the fabric can coact in the jjoint, even if their collective width is greater than 100 % of the fa-bric width. The individual loops (5) along at least some portion of the end edges (3, 4) of the parts (1, 2) are therefore formed from at least two juxtaposed threads (7, 8; 11, 12) crossing each other at least once (at 9) before the point of return into the fabric.

Abstract: REFRIGERATION SYSTEM UTILIZING AN EXPANSION DEVICE IN THE EVAPORATOR            ABSTRACT   A closed loop refrigeration system utilizing an expansion device in the evaporation system is disclosed. In one embodiment (Fig. 1), an expansion engine(170) is connected to the evaporator inlet (164) while a compressor (175) is connected to the evaporator outlet (172). Liquid refrigerant flows through the expansion engine (170) wherein it expands and drives the expansion engine. The compressor (175) may be driven by the expansion engine (170) or by a separate motor. A control circuit adjusts the refrigerant through the control valve (174) in a manner which maintains a desired degree of superheat of the refrigerant leaving the compressor. In an alternate embodiment (Fig. 4), the evaporator system has two evaporators (54, 204). An expansion device (180) is disposed between the inlet of the first evaporator (54) and the outlet (184) of the second evaporator(204). Partially subcooled liquid refrigerant from the first evaporator (54) is passed into the second evaporator (204) through an expansion valve (186) wherein it evaporates into a gas refrigerant. Liquid refrigerant is discharged into the expansion device (180) wherein it expands and raises the energy of the gas refrigerant arriving from the second evaporator (204) into the expansion device.Liquid refrigerant from the expansion device is fed to the first evaporator (54) while the gas refrigerant is passed on to a compressor. A control circuit adjusts the flow of the refrigerant into the expansion device (180).

Title: Fingerprinting bacterial strains using repetitive dna sequence amplification
Inventor: LUPSKI JAMES R
IPC: C12N1/11
Filed: 1992-10-21
Abstract: Oligonucleotide primers and methods for indentifying strains of bacteria by genomic fingerprinting are described. The methods are applicable to a variety of samples. The tasting procedure includes amplifying the bacterial DNA in the sample to be tested by adding a pair of outwardly-directed primers to the sample. The primers are capable of hybridizing to repetitive DNA sequences in the bacterial DNA and extending outwardly from one hybridizable repetitive sequence to another hybridizable re-petitive sequence. After amplification the extension products are separated by size and the specific strain of bacteria is deter-mined by measuring the pattern of sized extension products. The procedure to identify strains of bacteria by fingerprinting has a variety of uses including: identifying bacteria in infections, agriculture and horticulture plots, bioremediation, food monitoring, production monitoring, quality assurance and quality control.
