Expendable blades for use in tire buffing machines are disclosed having teeth with an outer edge and outwardly diverging leading and trailing side edges which form sharp prongs with the outer tooth edge for deep attack into the tire carcass; these teeth also having secondary or fine cutting edges comprised by the converging side edges of a cut-out, e.g., circular, in the outer edge of said teeth a...

Parallelepipedic packing containers are made and filled in succession by passing a continuous web of packaging material over a forming device which converts the web into tubular form with an overlapped longitudinal seam. The tube is then filled with the intended contents, e.g., a liquid and is then divided off into individual packing containers by first pressing the tube transversely at longitudin...

The power stroke of the within punch press results from the electrical interaction of an armature, attached in depending relation from a superposed positioned die set, and a solenoid coil located in the supporting base of the press. In assembling each component of the sub-assemblies consisting of the supported die set and of the supporting base, a positional relation is achieved for each component...

A ribbon drive and motor control system in which the instantaneous speed and torque output of a pair of motors are controlled interdependently to bidirectionally transfer ribbon or other web material between a pair of storage reels mechanically coupled to the motors at a uniform ribbon velocity and tension. The motors are electrically excited in series to rotate in the same direction with the back...

PURPOSE:To utilize a wind energy effectively and thus to increase output by rotating a wind mill to drive a generator with a strong ascending current. CONSTITUTION:A suction pipe 2 is arranged with its blowoff port 2b facing in a lower side opening 1c of a spiral cylinder 1, and a suction port 2a of the suction pipe 2 is provided against the wind together with a rewind port 1a of the spiral cylind...

A rotary die cutter for die-cutting blanks one after another has a blank feed unit, a pair of cylinders for die-cutting the blanks, and an endless member running synchronized with the cylinders. The blanks are gripped by grippers mounted at equal spacings on the endless member. The cylinders are adapted to allow the grippers to pass between the cylinders while gripping the blanks.

The invention is concerned with a ski boot structure particularly intended for downhill skiing, which comprises a boot shell (2), a boot sole (3), and an inclinable boot quarter (4) oscillably associated with the shell (2) for oscillation relatively thereto; the sole (3) has members (5) for binding the ski boot (1) to the body of a ski (13), which include at least three small plungers (6,7,8) arra...

A transferable enamel sheet and the process for producing it is disclosed, which consists of a carrier film, a release layer applied thereon, a paint or enamel layer and an adhesive layer whereby a neutralization layer of wax-type consistency, preferably carnauba wax is applied to the release layer which is of the dimethyl-siloxane type (silicone). It is possible to preform two types of transferab...

An apparatus and method for the comminution of plant matter, particularly of moist plant matter, for the production of corn cob mix, for example, provides that a rotor is rotationally mounted in a housing and provided with a drive, the rotor carrying movable blades and the housing carrying stationary blades so that there is a mutual interaction of the blades for comminution. The moving blades are ...

A device for the positive feeding of a yarn, particularly for knitting machines, having a rotatable storage drum adapted to have a yarn supply wound thereonto and withdrawn therefrom over a rim thereof, a stationary yarn guide element located below the rim and outwards of the periphery of the rim in a center plane extending through the axis of rotation of the storage drum, a yarn guiding element l...

A cutting tool having a high wear resistance is disclosed. The cutting tool consists of a plate-shaped body comprising a sintered cermet layer and a sintered body layer containing high density boron nitride or diamond, said sintered cermet layer constituting the center portion of the plate-shaped body and being surrounded and adhered at the side surface or at the side surface and upper and lower s...

A high capacity continuous solid bowl centrifuge is disclosed having longitudinal vanes which cooperate with helical flights to form longitudinal channels. The longitudinal vanes may be curved vanes or they may be planar vanes disposed either radially or at an acute angle relative to a radius from the longitudinal axis of the centrifuge. In operation, the solids/liquid mixture fed into the centrif...

A continuous flow device for separation of particles of differing densities in a centrifugal force field. Very small particles of differing densities that are normally very difficult or impossible to separate in the useful commercial gravity separation devices can be separated because of the increased settling force due to the centrifugal force field and also the buoyant force on the particles of ...

At least part of the residual water can be removed from azeotropes such as alcohol-water, ethylacetate-water, methyl ethyl ketone-water and acetonitrile-water mixtures by passing the azeotrope in contact with a substantially immiscible stream comprising a dessicant such as sodium sulphate or calcium chloride. The feedstock freed of at least a portion of its water and the hydrated dessicant are sep...

A connecting method and a container wherein a connecting tube of a blood pump or humor circulating circuit is connected to a tube such as a cannula mounted on a circulatory system organ in such a way that no bubbles enter the tubes, in order to pour blood or humor substitution fluid into the circulatory system organ.

The specification relates to a supporting arm capable of being turned freely itno different positions, which is made up of at least two straight sections articulated to each other, such a section containing a parallelogram formed by articulated arms in such a way that the ends of the same description of the two long parallel articulated arms (8, 6) of the parallelogram are articulated to a common ...

A plate stack clamping element is formed of adjacent leaf springs preformed to diverge where they extend beyond the plate stack. Compression of the diverging portions creates large area contact clamping force against the plate stack.

A high capacity continuous solid bowl centrifuge is disclosed having longitudinal vanes which cooperate with helical flights to form longitudinal channels. The longitudinal vanes may be curved vanes or they may be planar vanes disposed either radially or at an acute angle relative to a radius from the longitudinal axis of the centrifuge. In operation, the solids/liquid mixture fed into the centrif...
