Abstract: An artificial bait of the type of a hollow, transparent body having a front, blunt portion, wherein the front or head portion of the bait is of a color distinct from that of the rest of the bait. The main body color of the bait is provided by a sheet-like insert in the body extending from the rear end to a point spaced from the end wall of the head portion. The front end wall is preferably concave and is provided with a paint layer, preferably applied to the exterior. Since both the front wall and the rest of the body is moulded from a transparent plastics material, the color of the paint applied to the front wall is also displayed at the side wall of the body. Accordingly, the color of the front portion, preferably red, is visible not only in front view but also at virtually any angle of viewing of the bait, except the exact rear view.

The taper of the body is selected so that the center of gravity is approximately at the longitudinal center line.

Abstract: An animal toss trap includes an enclosure having openings for animal entry therethrough. A generally elongated gate displaced from these openings and positioned within the enclosure presents an animal capture compartment therebeyond. In a normal gate position, the horizontally disposed spikes project from one end of the gate towards a wall of the enclosure so as to present a means of entry or path into the animal capture compartment. An animal on initial progression through this path pushes against the spike tips causing the gate to swing in response thereto. During subsequent animal movement the discomfort of the spiked tips upon the side of the animal further urges the animal through the forward path and into the capture compartment. The gate, being spring biased, returns to a normal position after the above animal entry. A lock, released by an animal upon entry into the path is provided to prevent the gate from being opened by a previously captured animal.

Abstract: The automatic trap for catching cockroach mainly includes an automatic control mechanism. As cockroaches enter into the trap, they will inevitably touch a switch of said automatic control mechanism to drive a slipping plate forward and further to automatically sweep these cockroaches into a confinement cell. After that, the slipping plate will be also automatically back to its original position, restoring the control function of the automatic control mechanism, which is the particularly advantageous feature of the present invention.

Abstract: Apparatus by which a steel leg-hold trap is rendered humane so that the trapped animal is recovered alive and uninjured. A resilient material, such as vulcanized rubber, is removably affixed to the opposed jaws of the trap so that the animal's leg is uninjured when the jaws are closed thereon. The first reaction of any animal caught in the leg-hold trap is to bite and chew on the trap. A nipple extends from the resilient material and contains a substance, such as a tranquilizer, which subdues the animal when the substance is orally ingested. The nipple is a hollow chamber which extends away from the trap jaws so that the animal, when trapped, inherently attacks and bites the nipple, whereupon the chemical substance is released from the chamber and enters the oral cavity of the animal, causing the animal to become subdued. A tranquilizer is preferably placed within the nipple so that should the incorrect animal be trapped, he can subsequently be released unharmed.

Abstract: A toy telephone has a handpiece and a cradle for the handpiece. The cradle is spring urged upwardly at a controlled rate when the handpiece is lifted. A motor driven phonograph reproduces recorded sound only when the cradle is in its upper position. When the handpiece is placed on the cradle, it moves to its lower position and in doing so causes the phonograph motor to rotate intermittently in a reverse direction. Upon reverse rotation of the motor a clapper on the motor shaft moves outwardly to ring a bell located near the motor. Movement of the cradle actuates switches to control the direction of motor rotation.

Abstract: An articulated doll including an internal arrangement for allowing the doll to sit down from a standing position without the assistance of the doll user. With the doll in a standing position and the arms upright, the user rotates the arms to a down position and then releases the arms. After a predetermined time interval, the internal arrangement of the doll causes the doll to move from the standing position to a sitting position. When the doll is returned to a standing position, a control mechanism located on the doll torso is actuated to lock the legs of the doll to a standing position. The doll is also capable of being walked by the user holding the doll by the arms and alternately lifting one leg and then the other off the walking surface. The leg lifted from the walking surface pivots and the doll takes a step.

Abstract: Packing machines for the manufacture of packing containers frequently produce these from web-like material, which is supplied to the machine in the form of a roll. During the production the material web is advanced through the machine along a path defined by guiding rollers, guiding rails and similar elements.

This difficulty is eliminated in accordance with the invention in that a front and a back part of the material web are advanced alternately. In accordance with the invention, moreover, an arrangement is proposed with first and second web-advancing elements, which operate with alternating working strokes.

Abstract: A turbine wheel is encased in a closely fitting cylindrical housing filled with water. The circumference of the wheel is fitted with a plurality of chambers defined by axially extending vanes, each of which may have a radially flat portion tending to propel water tangentially following the direction of rotation of the wheel. Each chamber communicates to a respective radial conduit, and through the conduit to a central manifold.

Water displaced downwardly out of the bottom chambers is diverted into a bypass conduit running outside the closely fitting housing and travels upwardly to be reintroduced into the chambers as they near the top dead center position. The water is preferably introduced over a fraction of the chambers' axial dimension so that the air may be quickly displaced to the side (axially).
