Abstract: A synthesis color photographic map, on a predetermined scale, covering a wide geographic area. It is formed of a number of color photographic base maps each covering a selective portion of the wide geographic area and on the predetermined scale. These photographic base maps are assembled together to form the synthesis map. Each of the photographic base maps is a photography of a forestry base map which covers one of the selective portions of the above-mentioned area on a scale which is larger than the said predetermined scale. These forestry base maps are colored according to a given identification color code and then color photographed and scale reduced to the aforesaid predetermined scale.

Abstract: A tree harvesting machine is disclosed which is of the type having a wheel-mounted frame, a tree harvesting mechanism at the front and a berth at the rear for accumulated felled trees. An inverted tree grapple is provided forwardly of the berth and is mounted to the berth so that it can be slid to and from the berth whereby the grapple may be held close to the berth during accumulation of felled trees and moved away from the berth when loaded. In this last position, the center of gravity of the load has thus been shifted forwardly. The berth itself is pivoted to the frame to allow loading to take place in rearwardly inclined position. Once loaded, the berth may then be uprighted easily since the center of gravity of the load has shifted forwardly.

Abstract: A method for cleaning a septic tank provided with at least two successive fermentation and decantation compartments connected to each other by a lateral opening. According to this method, the light and/or heavy sludges contained in each compartment are pumped and discharged in a waste tank whereas the bacteriological liquid medium of both compartments is pumped out and stored in a storage tank. The liquid medium kept in the storage tank is reintroduced into the septic tank after the same has been cleaned, to reactivate said tank thereby making it immediately operative. A tanker especially designed for carrying out this method is also disclosed.

Abstract: A safety valve for automatically stopping the flow of a fluid brought by a conduit into a reservoir when the level of fluid in the reservoir reaches a maximum predetermined height. This valve is of the type comprising an obturation plate pivotally mounted in a housing provided in the supply conduit proximate the outlet of the conduit, and a control device including a float mounted at the end of a rod arranged to rock the obturation plate from an open position where it allows the fluid to flow freely to a closed position where it obturates the conduit to thereby stop the flow of fluid and consequently its arrival into the reservoir when the level of the fluid has reached the predetermined maximum level aforesaid. The pivot on which the obturation plate is mounted is provided on the outside of the housing and of the supply conduit, and is preferably made up of two aligned stub axles respectively seating into two small bearings made solid with two opposed external surfaces of the housing of the obturation plate.

Abstract: A six port network for use in determining a complex reflection coefficient associated with a microwave network. A directional coupler is connected between first and second ports of the six port network for transmitting microwave energy from a microwave source connected to the first port, to the microwave network connected to the second port. This coupler provides two signals respectively representative of the microwave energy supplied to the first port, and of the transmitted microwave energy reflected at the microwave network. The six port network further comprises a microwave circuit for producing from the two representative signals, four microwave power readings respectively associated with third, fourth, fifth and sixth ports of the six port network and proportional to .vertline.a.vertline..sup.2, .vertline.1+.alpha.e.sup.j.phi. .GAMMA..vertline..sup.2, .vertline.1+.alpha.e.sup.j(.phi.+120.degree.) .GAMMA..vertline..sup.2 and .vertline.1+.alpha.e.sup.j(.phi.-120.degree.) .GAMMA..vertline..sup.

Abstract: A structural log-like member for use in constructing walls, having an outer wooden wall and an inner wooden wall. Wooden spacer members connect the inner and outer walls together in spaced-apart parallel fashion. The spaces between the walls and spacer members can be filled with an insulation material. In use, the structural members can be stacked one on top of the other to form a wall.

Abstract: A fluid flow sensor, comprising a tubular element having a greater diameter than and vertically mounted on a pipe for serially interconnecting two portions of this pipe. One portion is connected to the upper end of the tubular element while the other portion is connected to its lower end. A magnetic piston is slidably mounted within the tubular element and is therefore free to move along it. A by-pass conduit interconnects the lower portion of the pipe with the upper portion of the pipe. The piston moves upwardly in the tubular element when the fluid flows. Fluid flows from the portion of the pipe connected at the lower end of the tubular element to the one connected at its upper end through the by-pass. The piston moves downwardly by gravity to the lower end of the tubular element when the fluid stops flowing. A coil wound around a portion of the tubular element produces in electrical signal when the piston moves in the tubular element.
