Title: Manual soldering device with storage chambers
Inventor: FEINLER SIEGFRIED
IPC: B23K3/06
Filed: 1995-09-27
Abstract: There are prior art manual soldering tools (1) consisting of a heat-insulating handle (2), a soldering tip (4) and a heating device (3) generating the soldering temperature. Here, in order to allow single-handed operation, there are acceptance chambers (12, 27, 48) from which both solder and flux may be supplied to the soldering point for soldering components. Damaged components must first be removed in order to exchange electronic components and subsequently replaced by new ones. These two processes cannot be undertaken with the prior art manual soldering tools. The invention provides a manual soldering tool in which it is possible both to solder components and draw superfluous solder or flux. This is achieved in that in the handle (2) and/or near the heating device (3) there is at least one acceptance chamber (27, 48) for solder and/or flux from which solder and/or flux can be metered to the soldering tip (4) and there is an extraction chamber (12) into which superfluous solder or flux can be drawn.

Title: Heated die lips system
Inventor: BENTIVOGLIO ALFREDO
IPC: B29C48/10
Filed: 1997-05-06
Abstract: This invention of Heated Die Lips System is specifically designed for use in Film Extrusion Dies. Use of such a system allows Film Extruders to be run at higher production rates with narrower die gaps, while eliminating the melt fracture properties. This Heated Die Lips System, is installed in the final die land area of the extrusion die, on each side of the die gap. It applies direct heat to the polymer melt as it exits the die lips, and reduces the melt viscosity. Thus the 'Critical shear stress' value of the melt is reduced. This results in postponement of the melt fracture property of the film and higher production rates are achieved without melt fracture. Furthermore, this system has been designed so as to insulate it from the main block of the die, minimizing heat dissipation and providing an enclosed system for uniform heating of the die lips.

Title: Planting assembly for a seed drill
Inventor: ZIMMERMAN ROBERT
IPC: A01C5/06
Filed: 1997-05-27
Abstract: A seed drill includes a novel planting assembly combining press wheels for packing angular sides of a furrow and a runner immediately behind and longitudinally aligned with the press wheel. The runner includes an arcuate front edge that is juxtaposed immediately behind the coulter, thereby preventing accumulation of field trash between them. The runner extends rearwardly from beneath the press wheel and is transversely guided on the supporting vehicle frame of the drill to maintain it in longitudinal alignment within an open longitudinal slot cut through the soil and intersecting the base of the packed furrow. Seed is dropped into the open slot prior to being covered with soil. Moist soil can be packed along the sides of the furrow to maintain the furrow in an open condition during seed germination and plant emergence. Highly accurate planting depth control can be achieved, with provision for upward relative movement of the runner as required by encountered field conditions.

Title: Method for recycling of rubber products
Inventor: RYAZANOV ALEXANDER VASILIEVICH
IPC: C08J11/10
Filed: 1995-03-16
Abstract: The aims of the present invention are: to reduce energy consumption during the reprocessing of rubber-containing articles, simplify the separation of nonrubber materials, improve the separation of different materials, improve the reprocessing quality and the quality of the secondary raw material produced, and reduce equipment wear and running costs. To that end, deformed industrial rubber articles undergo treatment with ozone-containing gas which results in splitting in the rubber and a breakdown in the physical integrity of the article and facilitates the removal of strengthening elements without mechanical cutting or crushing. During the deformation of the rubber fragments thus formed in an ozone-containing environment, they can be reduced to particles of the requisite size (0.01-5 mm). The basis of the process is the physico-chemical method of breaking down rubber under the action of ozone. Placing the rubber material under tension substantially accelerates disintegration.

Inventor: LIVINGSTON ARTHUR H
IPC: B31B15/00
Filed: 1998-05-28
Abstract: Containers are conveyed through an oven on a conveyor to cause a foamable material on each container to foam and become a heat insulative layer. The containers are supported on respective holders of the conveyor, which prevent the containers from contacting one another. Preferably, the holders support the containers loosely, to enable the containers to wobble relative to the holders under the influence of oven air currents and conveyor vibration. The holders thus do not make contact with any given point on their respective containers for a time period that is sufficient to enable the holders to draw enough heat away from the container to adversely affect the foaming operation. The containers are conveyed in single file, along a serpentine path through the oven.
