Abstract: An improved hand tool for removing shingles and accompanying roofing material from skip sheeting roof boards. The tool has a handle shank 11 with a drop leg 20 extending down from its front end. A prong 21 extends forwardly from the lower end of drop leg 20. A U-shaped structure 3 has its bight 30 connected to the drop leg 20 with its legs 31 and 32 extending forwardly parallel to and above the prong 21 which is positioned centrally beneath legs 31 and 32. A cross bar 4 connects the forward ends of legs 31, 32, and a brace 12 connects the center of cross bar 4 to the front of handle shank 11. The prong 21 is inserted into the gap between adjacent roof boards and advanced forwardly. The shingles are lifted and trapped between prong 21 and legs 31, 32. As the handle shank is lifted and worked upwardly and downwardly while advancing, the shingles and accompanying material are thus removed from the roof boards.

Abstract: A post-and-beam mechanism easily connectable to a standard car dolly carries on its beams a standard boat trailer, loaded with boat and outboard motor, above the front end of a towed vehicle on the dolly, with the rear, heavy end of the trailer and boat located forward most. A motor home may tow, to the destination site, the dolly thus loaded with towed vehicle, boat trailer, boat and motor. The post-and-beam mechanism is pivotably swingable from a low position for loading the loaded boat trailer thereon; to a high position for carrying the loaded boat trailer. The towing is safely done, with advantageous forward weight distribution of the carried trailer, boat and motor, and with short combined overall length of towing vehicle and towed vehicle, for easy driving and parking. When the destination site is reached, the towed vehicle is unloaded from the car dolly, and the mechanism may be lowered from the high position to the low position for unloading the boat trailer.

Abstract: Disclosed is a hand held, cordless electric, coping saw, which has a "U"-frame with a handle at one end of the "U". A battery and motor power the saw. The blade of the saw is endless and is round cylinder-type flexible blade trained in a generally rectangular loop about four wheels, one mounted in each corner of the "U", three of them idle wheels and one of them functioning as the drive wheel. The drive wheel is located at the handle end corner of the "U". At the other end of the "U", the frame has a "floating" corner piece housing one of the idler wheels and being spring biased away from the main part of the frame to provide saw blade tensioning.

Abstract: Disclosed is a method of and apparatus for remotely time setting a ballistic fuzing device from an off-board setting device non-conductively coupled to the fuzing device. The fuzing device has a free running or astable multivibrator with non specific frequency tolerance specifications In the practice of the invention, the fuzing device contains a means of generating a time base from a conventionally designed multivibrator circuit, such as an R/C circuit, but not one that utilizes a quartz crystal as its time base. Said multivibrator is set into oscillation during a programming time, at which time the frequency or period of oscillation is measured, and via proper electronic circuits said period is transmitted from the fuzing device to a setting device via a nonconductive link.

The assembly may be swung on its pivot from fishing position to a storage position in the center portion. The lids may be swung across one side of the center portion and locked to cover part of the assembly, and the flagpole may be swung and locked in position with the flag on the other side of the center portion covering the rest of the assembly.

Abstract: A floating tip-up fishing rig is provided having a float body, a flagpole, a spring means mounted atop said body at the rear end thereof and connected to the bottom portion of the flagpole urging it to an upright position. An opening vertically through the float body is disposed near the forward end thereof, and has a flared out widened bottom end. A fishline bobbin is swivel-mounted to the bottom of the body centrally thereof within a conically flared out cavity therein. A fishline is coiled about the bobbin. Extending down from near the free end of the flagpole is a cotter pin connected to the flagpole at the eye end of the pin. The cotter pin extends through the opening when the flagpole is in a horizontal or slightly raised position, and the fishline may be pulled from its coiled up portion on the bobbin and set in the closed portion of the cotter pin between its eye end and flared open end.

Abstract: A combination summer-and-winter tip-up fishing rig is provided which may be used on the ice in winter weather and on open water in summer weather. The rig has an inverted dish-like body of light weight insulating and floating material, a flagpole, a spring means on said body at one edge thereof urging the flagpole to an upright position. The body has a top deck and a perimeter side wall extending down from the top deck, to form a hollow interior, divided by walls into a large cavity and a small cavity. A fishline reel spool is rotatably mounted in the large cavity with its vertical shaft extending through the top deck. The shaft has a horizontal arm above the deck which extends over the flagpole to hold the flagpole nearly horizontal in the fishing mode, and which turns to release the flagpole to the upright tipped-up mode when a fish strikes. A cotter pin may be swivel-mounted to the underside of the top deck centrally thereof extending down therefrom.

Abstract: Disclosed is a cabinet for storing containers of volatile hazardous liquids, the cabinet having therein, in a place out of the way of the containers stored therein, a vapor trap for adsorbing and/or neutralizing vapors of said liquids. The vapor trap may be fastened in the cabinet to be easily removed, and replaced, or to be chemically or mechanically recharged and then replaced. The trap has an outer perforate shell containing therewithin vapor trapping material such as a vapor adsorbing and/or a vapor neutralizing material. The material may be in loose, particulate form or may be carried in one or more fiber sheets. The shell may be of rectangular box shape or of right-triangular box shape, to enhance positioning the vapor trap in the cabinet in a place out of the way of the containers. The vapor trapping material may be activated carbon, impregnated or unimpregnated, and/or may be slaked lime or activated alumina.

Abstract: A floating tip-up fishing rig is provided having a float body, a flagpole, and spring means mounted atop said body at one end thereof and connected to the bottom portion of the flagpole urging it to an upright position. A tube is disposed vertically through the float body substantially centrally thereof, and extends below and above the body. The tube has a reduced wall or groove portion immediately below the body and above the bottom of the tube, and a fishline is coiled about the tube in that groove portion. Extending down from the central portion of the flagpole is a string, the bottom end of which is connected to the eye end of a cotter pin. The cotter pin has a flared open end opposite the eye end and an elongated closed portion in between those ends. The string and cotter pin extend down into the tube when the flagpole is in a horizontal or slightly raised position. The tube has a J-slot in its top end into which the flagpole is placed for holding it in horizontal position.

Abstract: Disclosed is a one-piece thermoformed plastic package blank having complementary first and second portions connected by a hinge, with a flange in one plane surrounding the portions and the hinge. The hinge in its central zone is at its maximum height above the flange plane, but is at a lower height in its end zones, tapering off to zero height at its ends, blending into the flange plane. The sidewalls of the hinge are of a negative draft slant undercut in the central zone, but are of a positive draft slant in the end zones of the hinge. To produce the finished package, the blank is die-cut to trim the flange and cut two "V"-shaped notches therein, each notch extending from the flange edge slightly into an end of the hinge, at the point of the "V". The resulting package has smooth hinge end edges and corners, without any sharp protrusions, and it folds properly and easily from open-mode to closed-mode, without application of considerable or excessive force.
