This invention relates to a remote controlled apparatus and method for training retrieving and other hunting dogs and replaces all functions field assistants would normally perform during training. These functions include throwing multiple birds and retrieving dummies from different locations, in various directions and at various heights and angles, a gun shot sound, visual and audible assistance for the dog and protecting stored birds and retrieving dummies from the inexperienced dog. The appar...

A tappet made of Al alloy is used in a valve operating mechanism of an internal combustion engine of a vehicle. On the whole outer circumferential surface of the tappet, a helical projection and a helical groove are formed alternately to form an uneven surface. A plurality of uneven surfaces are formed on a ridge of the projection at regular intervals. The outer circumferential surface is coated with a wear resistant Fe film by thermal spraying. The uneven surfaces on the projection provide high...

A sports training device has a base to hold the ball. Straps are attached to the base and secure the ball to the base. Mating fasteners allow the straps to join to one another and result in the easy set up and disassembly of the training device.

A method of playing a game on a rink including a center planar playing surface surrounded by a ramped area which in turn is surrounded by an upper platform area. Two goals are provided opposite to one another on the planar playing surface. Each player utilizes a modified lacrosse stick used to manipulate a ball into the opponent's goal. Unlike, lacrosse, the ball may be rolled on the ground as in hockey, although the main movement of the ball will be airborne from net to net. Passing maneuvers a...

An arched metal-ceramic substrate with one ceramic layer and with a metal coating provided on the top and bottom of the ceramic layer which is curved around at least one axis parallel to the plane of the substrate such that it forms a convexly curved surface on the bottom. The thickness of the metal coatings on the top and bottom of the arched ceramic layer is the same.

A method for preventing bulges in liquid packaging. Disclosed is a mechanical process for squeezing the carton during the carton sealing process. When sealed, a partial vacuum is created, thus making the filled and sealed carton side walls concave. Over an extended period of time, the vacuum will release to the point of having a straight wall carton.

The invention relates to novel laser optics for shaping at least one laser eam which has a linear or strip-shaped cross section which extends in the first axial direction (X-axis) perpendicular to the beam axis (Z-axis), with at least two optical shaping elements which are located in succession in the beam path, and of which at least one is an element through which a laser beam has passed, and which form an optical arrangement, in which at least one laser beam is fanned out in one plane (Y-Z pla...

An apparatus for stamping skins including a plurality of stamping units of thermal transfer type, positioned side by side trasverse to a direction of advancement of the skin. Each stamping unit is provided with at least one skin presence sensor which enables the corresponding stamping unit to operate, and further includes a skin advancement sensing element.

A microcooler with channels through which coolant flows. The channels are formed by individual cooler layers having a region which is structured in the manner of a screen and having a plurality of openings with edge lines closed and with material bridges or material regions remaining between these openings. None of the openings on any of the cooler layers form a continuous channel which extends from a collection space for feed of the coolant to a collection space for drainage of the coolant. The...

A unitary composite abrasive disc for one-pass grinding and finishing of a workpiece comprising a flexible epoxy rim bonded to a rigid core.
