Abstract: The invention relates to a method of producing scaffolds, especially ladders. In order to provide a construction solely made of an insulant material, the rails (5) and the rungs (1) of a ladder according to the invention are wholly made of reinforced plastic and are joined to each other by means of a polymeric cold junction method. Thereby a hole (18) is provided on the side of the rail (5) and a suitable amount of a mineral or fiber reinforced monomer mixture (2) is added therein, whereafter the rung (1) is positioned thereto and the resultant whole Is turned upside down, the monomer mixture being polymerized by means of heat, a catalyst and/or an accelerator. So the monomer mixture flows around the junction of the rung (1) and the rail (5), polymerizing therein and forming a tight joint between the rung and the rail.

Title: Corner construction for log home
Inventor: WRIGHTMAN RONALD
IPC: E04B2/70
Filed: 1989-11-23
Granted: 1991-12-31
Abstract: An elongated log is formed substantially rectangular in cross section and is provided with a reduced portion where two logs intersect one with the other at right angles. The reduced portion has a double angled sloping upper surface and a similar sloping lower surface at right angles to said upper surface so that water or moisture sheds easily and towards the outside. When two logs intersect, impaction is not necessary as a sealant is used to seal the joint. This makes manufacture easier and less critical and appearance is improved by the provision of relieved side edges which hide any imperfections of fit when the logs are assembled. Beveled side faces eliminate any end play when the logs are assembled even although the logs do not have a tight fitting interlocking relationship insofar as the major portion of the junctions between logs is concerned.

Abstract: A spray nozzle to discharge liquid material in a pattern which has the same quantity of liquid material in each increment of the pattern. The nozzle may be used in various orientations in which a supply of pressurized liquid is available, with the liquid being discharged generally in a lateral direction in relation to the path of movement of the nozzle thereby rendering the nozzle quite effective for use in discharging liquid fertilizer, growth retardant, insect sprays, orchard spray material and the like in an effective manner. In one embodiment of the invention, a nozzle is provided with a discharge passageway, a downwardly-opening, inverted U-shaped extension of the passageway, and a curved blade diffuser in the inverted U-shaped extension of the passageway to break up the liquid flow into droplets and to cause the droplets to be discharged in a lateral pattern so that a substantially equal quantity of liquid material is discharged in each increment of the path being traversed by the nozzle. In another embodiment of the invention, an additive injector is incorporated into the nozzle which enables a controlled quantity of liquid material to be injected into the main flow of liquid being discharged, with the diffuser effectively serving as a mixer for the additive and the liquid being discharged from the nozzle.

Title: Method and apparatus for culturing autotrophic plants from heterotrophic plant material
Inventor: TIMMIS ROGER
IPC: C12N5/04
Filed: 1990-09-28
Granted: 1996-08-20
Abstract: A method and apparatus is disclosed for growing embryonic or other undeveloped plant material in a controlled, biologically sterile environment to produce plants capable of surviving in soil in an uncontrolled environment. Cloned somatic embryos of a particular plant are individually embedded in separate sterile plugs comprised of a soil-like particulate medium.  A volume of aqueous medium comprising a source of carbon and energy for the somatic embryos, and plant growth regulating substances, if required, is added to each plug.  The sterile plugs are then isolated from the ambient environment while permitting exposure to light and atmospheric gases sufficient to effect development of photosynthesis in the developing embryos in the plugs. While in such isolation, the resulting plantlets develop roots and shoots.  The resulting autotrophic plants are then removed from isolation and the growth medium is altered to remove the carbon and energy source to limit the capacity of the medium to support plant harming microbes.  The plants are then transplanted.  Several embodiments are disclosed involving compartmentalized trays and covering films or bags by which embryo-containing plugs are kept isolated from each other and from the environment during development of the embryos.
