Abstract: A toy has a housing in which is rotatably supported at least one disc having a plurality of object members on it. The object members are fixed to the disc and therefore movable with it. The toy includes a motor which drives the discs via a clutch. The clutch has two positions, one an engagement position wherein the disc is driven and the other a non-engagement position wherein the motor is no longer capable of driving the disc. A movable member is mounted on the housing and positioned in association with the disc. By moving over the surface of the disc, the movable member is capable of individually contacting each of the obstacles on the disc and upon such contact, the movable member is capable of interlocking with each of the obstacles to stop the rotation of the disc and shift the clutch into the non-engagement position where it remains until otherwise acted on.

Abstract: A guide used in teaching where to hit an object ball with a cue ball such that the object ball is deposited in a pocket of a pool table includes a marker which dispenses a small spot of a marker substance on the felt surface of the pool table. The marker substance leaves a spot on the felt which indicates the exact point at which the cue ball must be aimed in order to have the cue ball correctly strike the object ball to propel the object ball into the pocket. The marking substance is such that it will not leave a stain. The marker includes a reservoir for retaining a supply of the marking substance and an orifice which is capable of dispensing a small quantity of marking substance. The marker is supported above the surface of the felt by a support which has at least one surface capable of fitting next to the object ball and this surface is located precisely a radius distance away from the orifice on the marker.

Abstract: A game of the type having a playing surface enclosed in a housing and including a launching mechanism for propelling an object across the playing surface is improved by locating a target on the playing surface distal from the object launcher and interspacing between the target and the object launcher an interference member. The game includes an actuation device which continually moves the interference member reciprocally back and forth in the path of the object. The interference member is capable of assuming at least one position wherein it can interfere with the movement of the object and at least one position wherein it does not interfere with movement of the object rendering it possible for the object to travel from the object launcher to the target.The interference member includes a first sliding member having a plurality of projections which move through channels in the playing surface as the first sliding member slides in the housing.

Abstract: The invention relates to a hydraulic engine with radial pistons, comprising girders which transmit the thrusts of the pistons and rest against strips secured to the cylinder block.The surface of the cylinder block has a degree of roughness at least equal to the following values given in reference to the currently applied norms 0.25 .mu.RA; 15 .mu.Rt; and 8 .mu.Rp.The invention finds its application in the production of a reliable engine.

Abstract: A toy game includes a housing having a plurality of target members positioned in a side by side manner near one end of the housing. An attack object can move from a central position in the housing toward the target members and if correctly positioned it can interact with the target members. The attack member is capable of two modes of movement, however, it can only move in one mode at a time. One of the modes of movement is a transverse movement essentially across the width of the target members. The other mode of movement is from a starting point near the central portion of the housing toward one of the objects. If the two movements are coordinated the attack object is capable of interacting with one of the targets. A drive motor moves the attack object in each of the modes of movement via a motion diverting mechanism which is capable of converting motion of the motor into one or the other of the modes of movement at any specific instance of time.

Abstract: The invention relates to a fluid mechanism supplied with pressurized fluid by means of a "dis-engageable" valve-seat. Such mechanism further comprises a controlled and independent device for re-engaging the said valve-seat. The invention finds an application in the production of a hydraulic relief engine for use on a trailer pulled by a tractor.

Abstract: A toy steam locomotive is described which includes a small electric motor which drives an apparatus for producing a sound simulating a steam locomotive, an apparatus for producing a sound simulating a steam locomotive whistle, and an apparatus for producing a visual simulation of a fire in a steam locomotive firebox. The apparatus for producing a simulated steam locomotive sound includes a resonator and a vibrating spring. A cycling member is attached to the spring and concurrently tenses and relaxes, lengthens and shortens and associates and disassociates said spring with a sound activating member. The apparatus for producing the sound simulating a steam locomotive whistle includes a housing having a fan located therein and an air inlet and air outlet. The air outlet is associated with a whistle and a sealing member seals the air inlet, but allows air to be drawn into the housing when the sealing member moves away from the air inlet.

Abstract: A bed structure which is primarily intended for use in an extension of the body of a motorhome extending over the cab of the motorhome can be constructed so as to utilize a support holding a mattress pad so that they are capable of being manipulated between normal use positions in which the support and the pad serve as a normal part of the bed to another non-use position in which both the support and the pad are located above another second support of the bed. This second support holds a second pad which is constructed so as to coact with the first pad on the first support so as to fit on top of the first pad when the first support and pad are shifted to the non-use position above the second support. A strap is provided for returning the second pad to its normal position when the first support and the first pad are moved back to their normal positions.
