Patent CA-2185338-A1 (CA)
Title: Refrigerated cargo container
Inventor: CLATERBOS JOHN K
IPC: F25D3/12
Filed: 1995-03-21
Abstract: A system for maintaining a cargo in a refriger-ated condition over an extended duration employs an insulated enclosure having both a cargo-enclosing por-tion (25) and a carbon dioxide-enclosing portion (28) separated by an insulated barrier (32). A finite amount of solid carbon dioxide is placed in the carbon dioxide-enclosing portion (28) at the beginning of the dura-tion. By properly insulating the barrier to provide a rate of heat transfer within a predetermined range the cargo is maintained in a refrigerated condition with-out replenishing the solid carbon dioxide for uniquely lengthy durations. Such durations are especially max-imized by employing such enclosures in the form of cargo-carrying containers of generally rectangular shape stackable vertically atop one another and or in close side-by-side relation to one another.

Abstract: The present invention provides a process for recovering a basic amine compound which comprises the steps of (a) supplying a CO2-containing gas to a carbon dioxide absorption unit in which an absorbing solution, which contains a basic amine compound, absorbs carbon dioxide; (b) bringing the gas, from which carbon dioxide has been removed, into vapor-liquid contact with a washing water at a temperature from 20 to 60°C in an amine recovering unit of a carbon dioxide removal tower, recovering part of the basic amine compound accompanying the gas into the water phase and discharging the gas as an exhaust gas of the carbon dioxide removal tower; and (c) collecting the basic amine compound which remains in the exhaust gas of the carbon dioxide removal tower by passing the exhaust gas pass through a demister at a temperature from 20 to 60°C. The basic amine compound can be recovered efficiently from the gas of the carbon dioxide removal tower by using the above process.

Title: Attenuated human immunodeficiency virus vaccine
Inventor: WAINBERG MARK A
IPC: A61K39/00
Filed: 1997-06-26
Abstract: Reverse transcription of retroviruses is initiated from a 18 nucleotide primer binding site (PBS), located within the 5' region of viral genomic RNA, to which the host cell-derived tRNA primer is annealed and also involves viral genomic sequences outside the PBS.  Significantly lower levels of viral DNA were detected in cells infected with proviral DNA clones of human immunodeficiency virus (HIV) selectively deleted in regard to a segment found immediately downstream of the PBS.  This segment is involved in efficient expression of each of viral DNA, mRNA, and infectious virus.  The deleted DNA clones are useful for the preparation of an HIV vaccine.

Abstract: An animal feed containing 1 .alpha.-hydroxylated vitamin D compounds. The vitamin D compounds cause improved utilization of phosphorus, calcium, potassium, magnesium, zinc, iron and manganese in animal feed so as to minimize, or perhaps eliminate, the need for supplemental quantities of these minerals in an animal diet. In addition, low phosphorus containing animal feeds reduce the polluting effects on the environment since less phosphorus is excreted in the animal's feces which are then spread on agricultural land.

Abstract: An injection-molded, low-cost unitary screw cap sealing closure for medical specimen containers has a flip-up pouring spout which may be closed down to reseal the container. The spout enables pouring dispensation of the liquid contents, and subsequent resealing. The pouring spout and its attached lid are housed in a rectangular recess in the top of the screw cap, and fit flush therewith when closed. The cap recess provides access for the entry of a finger-nail of a user, or other opening device beneath the lid edge, to pry open the spout. The spout lid is attached by way of a molded flexible "live" hinge. The pouring spout is molded to the front, underside of the lid. The lower front edge of the spout is sealed to the cap by a flexible sealing diaphragm. A small transverse bridge is in the cap recess, against which the pouring spout seals, when closed. The bridge carries a pair of latches which lockingly engage the spout sides. The spout is divided laterally into a liquid transfer portion and an adjoining small atmospheric vent tube portion, both of which passages are sealed closed when the spout is in its closed position. The spout and the free-end portion of its lid are sized to enter the mouth of a laboratory test-tube, while the cross-section of the spout liquid transfer portion permits the insertion of a urine dip-stick, an inoculation loop or a transfer pipette into the container contents.

IPC: A01K1/01
Filed: 1997-09-12
Abstract: An improvement that enhances the functioning and efficiency of hay rakes or hay forks of the type used in the cleaning of horse stables and the like, includes a wall assembly having a rear wall element and two spaced-apart side wall elements extending from the rear wall element, that are positioned relative to a hay fork of conventional design so as to restrict unintended transverse displacement of hay/manure mixtures over the rear and lateral peripheral edges of the hay fork. The bottom edge of the rear wall element has a U-shaped indentation formed therein and further includes a mounting flange of U-shaped cross section aligned with and extending from the indentation for straddling the handle of a conventional hay fork so that the wall assembly is retained and positioned properly relative to the fork portion of the hay fork. The rear wall element and the side wall elements are formed with interlocking rails and slots so that the side wall elements may be readily attached to and detached from the rear wall element by a sliding motion. An opening through the mounting flange receives a fastener to secure the wall assembly to the handle of a hay fork. A resilient latch near the forward end of each side wall is capable of engaging a tine of a hay fork to further secure the wall assembly to the fork. The wall assembly may be provided entirely independently of a hay fork for attachment to an existing fork structure, or it may be integral with the fork structure.
