Patent CA-2230045-A1 (CA)
Inventor: JARMAN PHILIP
IPC: B64D1/22
Filed: 1998-02-19
Abstract: A method of logging a tree includes the steps of cutting the tree part way through the trunk with a cut near the bottom thereof, leaving a connecting portion of the trunk connecting an upper portion of the trunk above the cut to a lower portion of the trunk below the cut. A helicopter above the tree is connected to a point near the top of the trunk.  The helicopter is moved away from the tree, thereby brewing the connecting portion and allowing the upper portion of the tree to be carried away by the helicopter. The method utilizes a helicopter logging tool comprising a body having a connection for a lifting device. There is an elongated guide connected to the body by a hinge. The guide extends vertically downwards away from the body when the tool is connected only to the lifting device. There is a pooh on the body to one side of the guide for engaging an object. When tile pooh engages an object and the body is lifted by the lifting device, the body rotates and the guide rotates about the hinge so that the guide continues to extend vertically. There is also a jig apparatus for cutting the tree. There are two guide bars, at least one of which has a stop mechanism. Spikes allow the guide bars to be connected to the trunk of the tree in horizontal, parallel positions on opposite sides thereof. A chain saw mount is slidingly received on each of the guide bars.  When a chain saw is placed on the chain saw mount and moved towards the trunk of the tree along the guide bars, the tree is cut to a position determined by the stop mechanism on the guide bars.

Title: Heat exchanger fin with efficient material utilization
Inventor: LIM ALEXANDER T
IPC: F28F1/32
Filed: 1996-09-26
Abstract: A heat exchanger (10) including a heat exchanger conduit and fins arranged on the conduit tubes (12, 12') to further heat transfer between the external fluid flowing over the fins (22, 22') and the fluid flowing within the conduit. The fins (22, 22') include a row of apertures through which tubes (12, 12') of the heat exchanger conduit extend. The leading (4, 6) and trailing (48) edges of the fins (22, 22') are contoured to substantially conform to isotherms around the circulating fluid flowing within the tubes (12, 12'). To achieve this edge configuration while also allowing for a dense packing of fins and tubes in a multi-row heat exchanger, the leading and trailing edges are wave-shaped such that adjacent fins can interfit together.

Patent CA-2240284-A1 (CA)
Inventor: LINDSAY ALEXANDER D
IPC: C05G3/90
Filed: 1996-12-10
Abstract: Improved solvent systems for the formulation of N-alkyl thiophosphoric triamide urease inhibitors. These formulations enable the preparation of stable concentrated solutions of N-alkyl thiophosphoric triamides for storage, transportation, and eventual impregnation onto solid urea containing fertilizers and incorporation into liquid urea containing fertilizer compositions. These formulations are comprised primarily of a solvent selected from the group consisting of glycols and glycol derivatives. Optionally, in addition to the glycol base solvent, the formulations can contain a co-solvent selected from the group consisting of liquid amides, 2-pyrrolidone and N-alkyl 2-pyrrolidones, and/or a nonionic surfactant selected from the group consisting of alkylaryl polyether alcohols. The presence of the co-solvent and/or surfactant has been found to impart desirable properties to the formulations under certain conditions. N-alkyl thiophosphoric triamides have been known for some time to be effective inhibitors of the activity of urease enzymes, however, commercial use has been inhibited by the lack of an acceptable carrier. They are often thermally and hydrolytically unstable and difficult to handle. The use of the solvent systems offers many advantages including: (1) improved stability of the active ingredient urease inhibitor, (2) excellent solubility characteristics; (3) extremely low flammability and toxicity of the solvents; (4) excellent cold temperature storage and handling characteristics with the addition of the liquid amide co-solvent; and (5) good adsorption characteristics onto solid urea containing fertilizers and excellent miscibility with liquid urea containing fertilizer formulations.

Filed: 1998-08-20
Abstract: A portable putting surface is formed of a plurality of separate panels each having opposite left and right side rails removably secured thereto. The side rails in turn have mating ends which are used to assemble the panels into a continuous surface. A continuous length of artificial grass or turf material (e. g., Astroturf, tm) is used to cover the panels to form a reasonably realistic putting surface. The side rails each include a slope adjusting screw, thus enabling the left and right sides of the surface, and different panels of the surface, to be adjusted independently of one another in infinitesimally small increments as desired. The present putting surface may be used to simulate side hill lies on a sloping green, and/or may be used to duplicate very closely the slope of any particular green, from any approach direction. The surface assembles and disassembles easily in a matter of a minute or so, and may be packed into an extremely small package for shipment or storage.

Title: Parathyroid hormone analogues for the treatment of osteoporosis
Inventor: MORLEY PAUL
IPC: C07K14/635
Filed: 1997-08-01
Abstract: This invention describes analogues of human parathyroid hormone which have increased activities in bone restoration, and increased bioavailabilities. The peptides described are derivatives of hPTH-(1-31) which are cyclized for example, by formation of Lactams between either Glu22 and Lys26 or Lys26 and Asp30. In addition, the natural Lys27 may be substituted by either a Leu or other hydrophobic residues, such as Ile, norleucine, Met, Val, Ala, Trp, or Phe. Typically, these analogues have enhanced abilities to stimulate adenylyl cyclase in rat osteosarcoma cells, and show increased activities in bone restoration, using the ovariectomized rat model. The analogues also show enhanced activities and bioavailabilities, as demonstrated by their hypotensive effects in the rat. An assay which correlates hypotensive activity with osteogenic activity is also described.

Abstract: The comminution and distribution device according to the invention can be used to crush comminutable, pumpable materials, in particular mechanically dewatered slurry, into roughly the same sized pieces, and feed them in controllable quantities to a downstream device, e.g., a dryer. To this end, the slurry is conveyed through a gap formed by two oppositely rotatable parts. In preferred embodiments of the device according to the invention, both parts exhibit recesses on the side facing the gap, which are designed in such a way that, when the two parts are turned opposite each other in the preset rotational direction, slurry strands with periodically alternating areas with smaller and larger cross sections are formed, transported outside and split at locations exhibiting smaller cross sections.
