Abstract: The invention relates to a drive train (1; 52) between a power take-off shaft (27) of a tractor unit (26) and the gearbox (34) of a trailer vehicle (33), the drawbar of which is coupled in a bottom hitching arrangement to the hitch (28) of the tractor unit (26), wherein the drive train (1; 52) extends above the drawbar beam. Depending on the rotational speed and length of the propeller shaft, a long propeller shaft may result problems in revolution that is agitated and vibratory. The novel drive exhibits smooth running properties and allows for easy handling.

Abstract: A stove for burning wood, coal and other fuels comprised of flammable solids that among other things produce one or more flammable gases when heating or burning. The preferred form of the stove has three modes of operation--a rapid burning mode, a normal or medium burning mode and a banked mode. The user makes a preliminary decision as to whether the stove is to be operated in its normal mode or banked mode. Thereafter, controlled by temperature responsive means, the stove moves itself fully automatically back and forth from the rapid burning mode to whichever one of the other two modes of operation has been preselected by the user.

Abstract: A stove for burning solid fuel such as firewood. a lower level air inlet opening is provided for so-called "primary air," and another air inlet opening is provided at a higher level for so-called "secondary air." The volume of air introduced into the stove from each inlet opening is separately controlled. An air metering means controls the amount of secondary air introduced into the stove through the higher level air inlet opening. The lower level air inlet opening and the air metering means both have a finite number of predetermined, fixed air transmitting conditions and no other air transmitting conditions. The lower level air inlet opening has preferably two predetermined, fixed air transmitting conditions--a maximum and a minimum. The air metering means has at least a predetermined, fixed maximum air transmitting condition and preferably also a predetermined, fixed minimum, transmitting condition. The level at which the two air inlet openings are located is specified.

Abstract: A knock down tapered pole for a power-line wherein the pole is comprised of a series of superimposed pole sections with each section including a series of U-shaped bent-corner plates of uniform cross-sectional thickness and a plurality of trapezoidal-shaped flat plates positioned between the bent-corner plates and where the corner plates and the flat plates are secured together by means of fasteners.

Abstract: Restraining device intends to protect the workman from falling while working at higher environments. The device consists of a fixed cable stretched along the area of interest. A gripping clamp which slides along the cable is attached permanently to the workman's belt. Clamp consists of a pivotal arm which, when a downward load is applied at the point of attachment of the belt, exerts a frictional force on the cable, sufficient to immediately terminate workman's fall.
