Inventor: MATSCHE NORBERT
IPC: C02F3/12
Filed: 1992-08-05
Abstract: In a two-stage activation plant, part of the activated sludge (sludge circuit (1)) from the first stage (11) is transferred to the second stage (12) and part of the activated sludge (sludge circuit (2)) from the second stage (12) is transferred to the first stage (11), so that mixed biocenoses are formed in both stages (11 and 12).

Title: Oil-body proteins as carriers of high-value peptides in plants
Inventor: MOLONEY MAURICE M
IPC: A01H5/00
Filed: 1992-04-15
Abstract: Methods and compositions for use therein are described for expressing a polypeptide of interest in a seed cell as a fusion protein with an oil body protein. By this means, the fusion protein is targeted to the oil bodies of a seed cell. The oil body is easily separated from other cellular material following lysis of the seed cell, for example by using the partitioning/surface properties of the oil body. The fusion protein may be isolated for example by affinity chromatography using antibodies directed to the oil body protein. Where desired, the polypeptide of interest can be recovered by treatment of the fusion protein with for example a pro-tease capable of recognizing a proteolytic recognition site in the oil body protein proximal to the N-terminus of the polypeptide of interest.

Title: Pressure relief valve with thermal trigger and movable seal plug
Inventor: WASS LLOYD G
IPC: F16K17/40
Filed: 1992-12-11
Abstract: A thermally activated pressure relief valve (10) includes a valve housing (12) with an opening (28) communicating with an interior of a pressure vessel, and a passage (78) from the opening (28), through a cavity (20) of the housing (12), to an outlet (26).

Title: Method and apparatus for controlled biological treatment of waste water
Inventor: WICKENS DENYS
IPC: C02F3/00
Filed: 1994-06-23
Abstract: ABSTRACT           A method and apparatus (1) for the control of biological treatment of waste water in which waste water is fed to a substantially air tight supported growth biological filter unit (2) that includes an exhaust gas vent (5). Dissolved oxygen is supplied to the filter unit and the oxygen consumption rate across the filter is measured by comparing the flow rate of oxygen into the filter (2) to the flow rate of oxygen exiting the filter through the gas vent (5). The feed rate of waste water is adjusted to maintain a predetermined oxygen consumption, thereby controlling the effluent quality.    The appropriate oxygen consumption rate to give a desired effluent quality is determined empirically for each system and type of waste water to be processed.

IPC: A47H13/00
Filed: 1994-07-18
Abstract: An outerlining fabric woven of warp threads and a weft thread and including at least two fastener portions composed of a male or a female member of a surface-type separable fastener, and a mesh portion of a predetermined width disposed between the fastener portions to separate them in the widthwise direction of the outerlining fabric, the weft thread being composed of a synthetic resin monofilament having a rigidity greater than that of any of the warp threads.  The outerlining fabric is attached to and along the top edge of a curtain, and when the curtain is to be attached to a curtain rail, a series of curtain attachment connector members each having a fastener surface are attached to either of the fastener portions of the outerlining fabric.  With the outerlining fabric, the vertical position of the curtain relative to the curtain rail can be changed among at least two positions.  Due to the rigidity of the monofilament in the outer-lining fabric, the top edge of the curtain is always held in an upstanding position even when the curtain attachment connector is attached to the lower fastener portion.

Patent CA-2130471-A1 (CA)
Title: Method of Bovine Herd Management
Inventor: EVERETT ROBERT W
IPC: A01K29/00
Filed: 1994-02-15
Abstract: A method of bovine herd management based upon a dynamic mathematical model. The method gathers data on milk production on a periodic or routine basis for each cow in the herd. The data includes factors denoting both the quantity and the quality of the milk being produced. A database for each cow is established and continuously updated. A mathematical herd management model is used to establish the database, wherein the gathered data is then modified and used to interpret and determine the actual productivity of each cow in the herd for that test day. Using this data, a manager of the herd can then breed those cows having a capability superior to their associates in the herd. Likewise, the less productive members of the herd can be culled or eliminated from the herd. Another aspect of the invention includes the use of the database to quantitatively assess the effect of change, including changes made in formulas, in environmental conditions and in breeding practices. Thus, for the first time, herd management can be scientifically controlled on a quantitative basis. Genetic evaluations can be made from the databases of many herds in order to select primary A-1, bulls capable of siring daughters in many herds. For maximum efficiency, databases of many herds can be combined or linked across the entire nation.

IPC: B25F1/04
Filed: 1995-01-06
Abstract: In order to enhance the availability of tools, a multi-function tool includes a handle having first and second ends with the first end having an opening for receiving a screwdriver tip, and the second end having an opening for receiving a tube which is releasably retained in relation to the handle by a collet. The handle has opposed side openings extending from the second end to a point near the collet. The tube is mounted for limited axial sliding movement relative to the handle from a position where one of its ends is retained by the collet to position where it is no longer retained by the collet to position the tube in alignment with the side openings in the handle. The tube is also mounted for pivoting movement when it is in alignment with the side openings to a generally transversely extending position. The tube cooperates with the handle in the generally transversely extending position to define a T-shaped handled for applying increased torque to the first handle end. With this construction, a screwdriver tip is also operatively associated with each of the ends of the tube to project outwardly of the second end of the handle when the other of the ends of the tube is retained by the collet.

IPC: A01B49/06
Filed: 1995-05-16
Abstract: A rig assembly on a combination row crop cultivator and chemical applicator includes a knife or other applicator device supported in front of the cultivator sweep and behind the disk coulter blade.  The sweep helps seal the chemical in the ground in certain soil conditions to prevent chemical loss, particularly when additional closing structure is not in use.  A selectively attachable, shank-mounted closing mechanism, preferably a press wheel, may be mounted directly behind the sweep to assure a good chemical seal.  Disk coulter support straps have flanges that provide a conveniently accessed mount for the applicator device and present minimal interference to trash and soil flow.   A simple bracket connects an arm on the closing wheel mechanism to a central portion of the sweep standard.  Numerous combinations of tools and tool mounting arrangements and adjustments are facilitated by the rig construction.
