Abstract: An assembly of parts which form a stud for construction use. This stud assembly greatly reduces the material content of the stud assembly and reduces heat transfer and noise transmission over the known prior art and comprises two parallely arranged U-shaped channels interconnected by a novel mesh connector which interconnects the channels at one or more points along their length and is expandable only in a direction transverse to the longitudinal axes of the channels.

Abstract: A beverage dispenser is disclosed which controls of the delivery and mix of a liquid from its source with an ingredient. The dispenser comprises a mixer which mixes the liquid and the ingredient, the mixer being in electrical isolation from the source of the liquid. The liquid is delivered from the source to the mixer thereby providing electrical continuity between the source and the mixer. A sensor in electrical communication with a control board detects the electrical continuity between the source and the mixer. The ingredient is delivered to the mixer upon activation by the control board after the sensor detects the electrical continuity.

Abstract: A truck containing air cylinders and associated pressure control and delivery apparatus for use in supplying breathing air and air for tool operation in remote rescue operations. The truck is shielded for protection of its equipment against damage due to impact. Separate breathing air and tool air regulation and delivery channels are incorporated.

Abstract: An air conditioning system is disclosed for cooling a cabin of a vehicle. The vehicle has combustion chambers and a cooling system which circulates vehicle coolant. The cooling system also includes a radiator and an intake manifold. The air conditioning system includes a source of a liquid gas which is connected to the combustion chambers with a first heat exchanger positioned between the source and the combustion chambers. A coolant line also extends through the first heat exchanger whereby a coolant passing therethrough is cooled via vaporization of the liquid fuel. A pump is connected to the coolant line and circulates the coolant through the air conditioning system. The coolant line is also connected to a second heat exchanger whereby coolant passing through the second heat exchanger is heated and thereby cools the air. The now heated coolant circulates back to the first heat exchanger.

Abstract: A vest and harness combination is disclosed comprising a sleeveless vest formed of a fabric material for covering the shoulders, front and back of a wearer. A harness comprising two pairs of spaced webs is secured to said vest. The first pair of spaced webs is attached to and extends longitudinally along the front of said vest. The second pair of spaced webs is attached to said vest and extends laterally of said first pair of webs at least partially around the vest. The first pair of webs extends over the shoulders of said vest, criss crosses the back of said vest and is fastened to opposite sides thereof. The first pair of webs at the point of criss crossing is provided with a slotted ring-like frame through which each of the first pair of webs extends. One of the pair of webs is provided with a second slotted ring-like frame at a point midway of the back of the vest. The other of said second pair of webs is provided with a slotted buckle at one end and a clasp at its other end for engaging said buckle.

Abstract: A snow ski or runner on which the user stands with both feet juxtapositioned and parallelly arranged with the longitudinally axis of the ski. Both hands of the user grasps and manipulates in a cyclic manner a movable handle. Each foot of the user controls a foot pad for causing a portion of the foot pad to penetrate and extend from the bottom of the ski for steering purposes when foot pressure is applied to the foot pads.

Abstract: A liquid fillable transparent doll formed of a plurality of hollow relatively movable body parts that are interconnected to form a common reservoir wherein a liquid filling the reservoir provides the color of the outer appearance of the doll.

Abstract: A swimmer's hand paddle in the form of a rigid planar member has a mitten-shaped surface area, larger than the human hand and wider in the palm area than in the area of the middle finger, and has an irregularly-shaped aperture of a width approaching the width of the hand positioned at a location on the paddle so as to be covered by the most sensitive area of the palm when the hand is properly positioned on the paddle. From one end of a proximal curved wrist edge to a point beyond the end of the thumb, the thumb side edge closely approaches the outer edge of the thumb and then curves inwardly and merges with a sharply curved distal end, whereas the little finger side edge extends with flared curvature from the distal end to the other end of the curved wrist edge.

Abstract: A door locking mechanism employing an internally mounted solenoid for providing both fail secure and fail safe operations employing a pivotally mounted keeper for selectively opening and closing a strike block with keeper being controlled by a locking yoke which is selectively movable by the solenoid.

Abstract: A practice device comprising a simulated golf club that is swung by a practicing golfer under the control of a sling that is anchored to a vertical wall. A proper swing is achieved when the sling is maintained in a taut condition throughout the course of the swing.

Abstract: A method and apparatus is disclosed for enhancing the combustion efficiency of an internal combustion engine having one or more combustion chambers. The apparatus comprises an electrical power source having a voltage output, a power supply in electrical communication with output of the electrical power source, and an electrolytic cell having a cathode and an anode immersed in an aqueous electrolytic solution. The anode and the cathode are in electrical communication with the power supply output. The power supply optimizes the voltage output of the power source for use with the electrolytic cell. In turn, the electrolytic cell breaks down the aqueous solution into a mixture of hydrogen and oxygen gases which is conveyed to the combustion chamber of the engine.

Abstract: A vehicular window cleaning apparatus having a wiper arm, wiper blade and drive means therefor in combination with a scrubber for intensifying the cleaning effort of the wiper blade. The scrubber is detachably connected to the wiper blade. A cam means is provided for rotating the wiper blade relative to the wiper arm for selectively and sequentially locking the wiper arm and scrubber against an associated windshield.
