Abstract: A boat transom and method of constructing same utilizing the outer skin of the hull and transom while still in the hull mold. A bulkhead is disposed in forwardly spaced relation to the outer skin of the transom and the space therebetween is filled with high tensile strength synthetic resin which may be of the polyester type blended with a suitable hardener. The resin includes entrained microspheres evenly dispersed throughout the transom body and ground fiberglass reinforced plastic scrap. The transom body is cast in a series of merging layers containing fiberglass reinforcing which extends in zig zag fashion from edge to edge of the transom body cavity and additional strands which extend in a skewed pattern. The bulkhead may be removed after the casting operation or may be allowed to remain in place. A further aspect of the invention involves the casting of a fiberglass reinforced synthetic resin transom body in a generally horizontal mold, or an upright mold, separate from the hull mold.

Abstract: An adjustable drill jig for drilling holes in an overhead work surface such as a ceiling by an operator standing on the floor. The device is portable and easily moved from one work area to another by one person. It may readily be adjusted from the floor to accommodate ceilings of different heights; to vary the depth of penetration by the drill; and to control the application of power to the drill.

Abstract: A knock-down lever assembly which enables the driver of a disabled automotive vehicle to move it manually for relatively short distances without assistance from others. The device permits the vehicle to be moved manually away from a lost traction area such as a pavement covered with snow, ice, mud, oil or other slippery substances, or from a traffic lane to the shoulder of the road.

Abstract: An improved lumbosacral backrest having a back engaging contour which is adjustable under power or manual operation to accommodate users' backs which vary widely in configuration and dimension. It has a contour defined by a segmented regulator spindle inserted between a foundation frame and resilient back support, the regulator spindle being adjustable along the back support and adapted to define a transverse plane of rigidity at the proper level and shape to provide comfortable support for the individual user's back.The backrest includes appropriate power means for actuating the regulator spindle to effect massaging action on the lumbosacral region of the back.It further includes manual means for adjusting the regulator spindle and which is operable when the power means for effecting massaging action has been deenergized.

Abstract: An energy efficient heat pump dryer for clothes and other washables having a sealed rotatable clothes tumbling drum and means for circulating a stream of heated drying air in a substantially closed path through the tumbling drum. The drum is journaled upon a combined bearing and air seal means at each end. A heat pump is incorporated as the source of heat for the drying air, as a means for recirculating heat from the drying air exhausted from the tumbling drum, and as a means for removing entrained moisture from the exhausted drying air. The dryer is adapted to operate from a 110 volt household power supply and requires no air vent to the outside.

Abstract: An improved injection gun system for lawn treatment adapted to permit selective application of a treating fluid by the operator as an incident to application of a main stream fluid through a hand held injection gun. The system comprises a pressurized source of main stream fluid, a pressurized source of treating fluid, a reach of hose including a large diameter conduit connected to the main stream fluid source and a small diameter conduit connected to the treating fluid source, an injection gun connected to the large diameter conduit of the concentric hose, and a fail safe cut-off valve interposed between the small diameter treatment fluid conduit and the injection gun for controlling the injection of treatment fluid into the main stream passing therethrough.

Abstract: A heavy duty tractor drawn lift deck trailer for transporting load holding pallet frame units each having a ground engaging support structure enabling it to be picked up for transport or dropped off for storage without need for additional equipment or personnel. The trailer features an over-center mechanical lock for the lift deck which will be power engaged as the lift deck is elevated into raised transport position and power released as the lift deck is permitted to descend to lowered loading position on the trailer support frame. The lock is connected between a point on the lift deck and a point on one of the trailer hinge panels and remains engaged when the lift deck is tilted for dumping.

Abstract: A two axis numerically controlled contour boring machine adapted for interior and exterior machining operations such as boring, facing, grooving, turning and back-facing. The machine comprises a headstock slidably driven along a first axis by a feed motor. The headstock supports a rotatable contouring head having a radial slide which is driven along a second axis perpendicular to the first axis. The radial slide is spindle actuated and includes adjustment means for removing backlash in the drive. The radial slide is adapted to hold quick disconnect type tools selected for the particular machining operation or operations called for by the machining program. The desired contours are generated in the workpiece by the combined motion of the headstock and radial slide along their respective axes under numerical control.

The latter is formed of natural rubber having good resistance to a wide range of aggressive chemical wastes.

Abstract: A lumbosacral backrest for use with chairs, beds and various other furniture, vehicle seats, and wheelchairs. The device, which may be portable or built-in, has an upstanding foundation frame of generally rectangular form, a yieldable back support on that frame, and a regulator spindle interposed between the frame and the yieldable back support. The regulator spindle is journalled for rotation longitudinally of the yieldable back support and may be stopped at any selected position within its range of rotational adjustment. This provides a transverse plane of rigidity across the back support at such selected position and thereby effects an adjustment in the contour of the back support. Adjustment of the regulator spindle may be accomplished manually or by power means.
