Abstract: A tree slasher in which the entire trunk of a tree may be simultaneously cut into a plurality of selected lengths to meet subsequent processing requirements. The slasher, while large, is mobile and may, if desired, be taken to the vicinity of the tree-cutting areas thereby to minimize the distances the tree trunks must be hauled prior to cutting.

Abstract: The invention comprises a hollow self-supporting ball, in the form of a football, basketball, volleyball, etc. made of translucent plastic material and having an internal source of illumination of such intensity that the ball may be used in the dark. A battery powered light source is mounted within the ball in a novel manner which permits ready removal from and re-insertion into the ball for actuating the light switch and replacement of batteries when necessary.

Abstract: Means for automatically extinguishing a cigarette when it has burned to a pre-determined position along its length. The means comprises a small sack of liquid, ordinarily water, positioned at the required location within the tobacco and the paper tube. The sack will be ruptured by the advancing heat of the burning tobacco and the released water will be in sufficient quantity to quench the flame.

Abstract: A machine for driving a spring pin into a work piece. The pins are automatically fed from a supply to the pin driving means. Pins of varying lengths and diameters can be accommodated by changing a few parts. The work piece to receive the pin is placed at a correct location below the driving means. The machine, when actuated, goes through one complete cycle of driving a pin into the work piece and reloading itself for the next cycle.

Abstract: Steam generation means utilizing first and second boilers, the first of which is a high pressure boiler located within or in very intimate heat transfer contact with the second boiler. The steam generated in the high pressure boiler is used to drive continuously or intermittently, a turbine and an associated electrical generator whose output activates electrical resistance units located in the boilers. These heating units supplement an external heat source to maintain steam pressure in the high pressure boiler. The exhaust steam from the turbine at reduced pressure is used to supply heat in any closed steam consuming device such as a space heating system. The condensate is returned to the second boiler which acts as a preheater for water to be pumped from said second boiler to said first boiler as needed.

Abstract: The invention is an article of manufacture in the form of specially shaped weight bearing units which are placed under the outer part of the user's feet. The units may be removably or permanently secured to the user's shoes. Through the use of the invention, the foot muscles can be developed and strengthened to overcome so-called flat feet caused by fallen arches.

Abstract: Means for connecting together sections of a radio frequency transmission line. The connection is electrically correct, waterproof and substantially self-aligning so that even under adverse assembly conditions proper connection of the ends of the sections can be readily made.

Abstract: The invention comprises an article of manfacture made principally of two lengths of chain in which the lengths, arranged either circularly or semi-circularly, have had their links welded together to form a pair of diverging units connected together at their upper ends by welding either to the under side of a top plate or to other connecting elements. Legs have been welded to the bottom portions to support the unit on a floor or other under surface. The units may be utilized to hold a quantity of logs adjacent a fireplace or if of proper size might be used as magazine racks or as holders of any other kind of relatively rigid material that could be placed thereon.

Abstract: Supplementary means for heating liquid in a steam producing boiler comprising an electrical heating unit located in the boiler, the current for which is produced by an electric generator driven by a steam operated turbine. The turbine may utilize all or only part of the steam output of the boiler. Where the turbine uses substantially all of the steam, the generator driven by the turbine will have excess capacity to be used to drive a motor. Where the turbine uses only enough steam to drive a generator sized to meet the needs of the heating unit, the balance of the steam will ordinarily be used to drive some major prime mover or to supply heat to a heating system.
