Abstract: Self aligning sled apparatus for spraying herbicide to the ground surface of the top of the crop row and under the low growing foliage of row crops. Alignment of the plurality of shield sled apparatus is accomplished by the trunks of the crop plants guiding the shield sleds spaning the furrow between rows. Each of the plurality of shield sleds is attached by parallel linkages to a horizontal tool bar secured to the self-propelled sprayer or tractor. The connecting parallel linkages allow each sled to move vertically, horizontally, and rotationally as needed independent of the tractor and of the other shield sleds. As the apparatus moves forward, shields affixed to the shield sleds engage the low crop foliage and lift it upwards in order that spraying mechanism near the rear of each shield sled may apply herbicide to the ground and weeds under the crop foliage.

Abstract: An improvement to a pair of locking pliers comprising an extension to the locking pliers handle having an elongated brace for holding and turning, said brace attached in an off-set manner to a collar which in turn holds the handle of the pair of locking pliers. The collar is so off-set from the longitudinal axis of the brace extension to provide alignment of a held tool in the jaws of the locking pliers with the longitudinal axis of the brace extension in order that by rotation of the brace extension, direct rotation of the tool, such as a screw or bolt, held in the jaws of the locking pliers, is accomplished, and such may be done at a relatively long distance from the locking pliers and tool so held, additionally being accomplished with added torque and speed over use of the locking pliers without the improvement.

Abstract: An intravenous fluid warmer includes an electrically heated warmer module receiving a low volume (10 ml.) disposable cartridge through which the fluid being heated flows. The module is configured as two spaced concentric elongated metallic heating elements having attached electric heaters and defining therebetween an elongated plenum adapted to receive the disposable cartridge. The temperature of the heating elements is individually monitored by separate sensors and an electronic temperature control module maintains the inner heating element at a slightly higher temperature (36.degree. C.) than the temperature (34.degree. C.) at which the outer heating element is maintained. The inner heating element is free floating through a limited range to accommodate manufacturing differences is the disposable cartridge. The cartridge, made of polystyrene or polycarbonate plastic, nests in the plenum in contact with the heating elements.

Abstract: A take apart wooden toy puzzle which, when assembled resembles a San Francisco cable car. The toy comprises a number of pieces, the majority of which comprise pairs of mirror image constructed pieces which align and are mutually interacting. Two key element pieces must be detected and removed from the puzzle in the correct order in order to disassemble the puzzle. The first set of these elements, the brake posts, must be removed. At this point, the cable car is able to roll upon its wheels without falling apart. Since this initial procedure leaves the toy intact, the next element to be removed is not easily ascertained. The next step consists of disengaging the second step of key elements, the tie posts, which are fitted top to bottom through the puzzle. Once the tie posts are removed, the toy is easily and quickly disassembled. When it is desired to assemble the toy, it is conducted in the reverse order of disassemblage. The pieces of the puzzle are held in place until the tie posts are inserted.

Abstract: A superior yo-yo toy exhibiting characteristics of a lengthened spinning time for performing tricks while retaining characteristic of returning to the hand of the operator when desired; and automatic return to the operator when the yo-yo rotational rate has slowed to a predetermined rate. The yo-yo string is attached to a free-spinning bearing surrounding the axle, the bearing operably connected to a centrifugal actuated spring loaded clutch mechanism so that when the yo-yo rotational rate slows to a pre-determined rate, the clutch mechanism engages the bearing, coupling the free-spinning bearing to the yo-yo and causing the yo-yo to return to the operator.
