Abstract: A page of paper or other suitable writing material having parallel long edges and parallel short edges as a first and a second fold which are not parallel to each other but connect the short edges of the page. The page further has a third and fourth fold parallel to the short edges. When the page is folded along the first and second folds, the distance between the first and second folds along the first short edge is greater than the distance between the first and second folds along the second short edge. When thereafter the page is folded along the third and fourth folds, the second short edge can be fitted within the first short edge to configure the page as an envelope.

Abstract: A channel letter has a rear surface for mounting against a raceway, wall, or a structure for supporting the signage, and sides defining the figuration of the letter or shape to be depicted. A lighting element is positioned against the rear surface of the enclosure. To retain the lens to the open front of the enclosure, a shoulder is provided along the inner surface of the sides thereof where the shoulder defines a plane parallel to the outer ends of the sides but is recessed therefrom. A planar transparent lens having an outer edge which is in the shape of the letter and sized to fit within the sides of the enclosure is retained against the shoulder by a suitable retaining means such as screws.

Abstract: An excavating tool has a tungsten carbide insert which is more wear resistant and not subject to breakage because of bring too brittle. The insert has a semispherical tip, a divergent midsection and a base with a conical rear surface. The insert is made with tungsten carbide particles sized between 1 and 8 microns and averaging between 2 and 5 microns, blended with particles of a binder of which the binder comprises 5.5 to 6.5 percent of the blend by weight, and the insert is sintered to a hardness of 89.5 Ra or more.

Abstract: An attachment is provided for interchangeably converting a ski simulating machine into a rowing machine, the ski simulating machine having a frame, a pair of skis slidably mounted on the frame to move in forward and rearward directions on the frame and means mounted on the frame for providing resistance to the pair of skis during at least one of forward and rearward movement. The attachment includes a seat mounted for guided sliding movement with respect to the frame, foot support means mounted on the frame for bracing a user's feet when the user is sitting on the seat, and means for coupling the resistance providing means for application to a user's arm movement during a rowing exercise.

Abstract: A tool mounting block for a cutting machine has a forward surface and an aperture in the forward surface for receiving the cylindrical mounting portion of a tool. To extend the useful life of the mounting block, an annular insert is fitted around the aperture such that the forward surface of the insert provides a bearing surface to facilitate rotation of the tool within the mounting block.

Abstract: The housing of a refrigeration expansion valve has a port which is in communication with the pressure feed back chamber of the valve. A pressure gauge may be attached to the port to read the pressure of the refrigerant discharged from the evaporator.

Abstract: A step knife for use in eye surgery has a blade which extends a predetermined length beyond a footplate. The blade has a sharpened lower edge and each of the sides have a sharpened portion near the lower edge and an unsharpened portion near the footplate.

Abstract: A machine for printing a plurality of colored patterns on the surface of a contact lens has a plurality of parallel oriented print stations each of which has an image die and an ink cup for applying ink into the image in the die. A slide is moveable between a plurality of the print stations such that a contact lens on the slide can receive printing at each of the stations. The slide also carries a vertically moveable print pad for applying printing to a lens and an indexing cleaning tape for cleaning the print pad.

Abstract: The invention relates to a fire-extinguishing device and a valve block for a fire-extinguishing device. In order to create a fire-extinguishing device which has a short reaction time up to the quenching of sparks, there is provided, in a fire-extinguishing device which has an extinguishant pipe (14) which leads from an extinguishant reservoir to at least one quenching site and there terminates in an extinguishant outlet nozzle (16), an extinguishant container (20) in the region of the extinguishant outlet nozzle (16). From the container extinguishant flows into the extinguishant pipe upon a pressure drop in the extinguishant pipe (14). A valve block proposed according to the invention for a fire-extinguishing device facilitates the fitting of such an extinguishant container.

Abstract: A squaring machine has an elongate housing with a rotatable spindle extending from one end thereof and attached to which is a tool for squaring the end of work piece. At the opposite end of the housing are first and second feed members, the first feed member in the form of a screw which is locked against axial movement within the housing, and the second feed member in the form a nut which is locked against rotation with respect to the housing. The feed nut is rotatably connected to an end of the spindle such that rotation of the feed screw will cause axial movement of the spindle. Also, the machine includes a first and second removable retainers, each of which has a pair of opposing jaws for clamping around a cylindrical work piece, however, the jaws of the first retainer are for grasping a work piece of a different size than the jaws of the second retainer.

Abstract: An ostomy pouch has a first and second panels of flexible material sealed to each around the edges to form a bag, and a aperture for receiving waste product from a stoma. A seal i provided on the inner surfaces of the two panels to seal waste products in the pouch before the pouch is removed from the side of a wearer.

Abstract: A doweling hole drilling machine includes a vehicle such as a tractor having a frame pivotally mounted to the side of the tractor. The frame is moveable around an axis parallel to the longitudinal axis of the vehicle from a first horizontal orientation to a second vertical orientation, and the raising or lowering of the frame is powered by hydraulic cylinders. Positioned on the frame are a plurality of parallel mounted spaced drilling machines, each of which is positioned for drilling a hole perpendicular to the longitudinal axis of the vehicle. Each of the drilling machines is mounted on a drive assembly for moving the machine axially to thereby force a drill bit in the machine to drill a hole. The frame is also laterally adjustable in a horizontal direction perpendicular to the longitudinal axis of the tractor and the lateral adjustment is also hydraulically powered.

Abstract: A door controlling device for opening and closing a door in a wall has a first arm, one end of which is mounted to the wall and the other end of which is pivotally attached to the second end of a second arm. The first end of the second arm is pivotally attached to the top of a door and is adapted for rotation about a horizontal axis at the first end thereof. An electric motor attached to the device has a shaft which drives a gear train, and an output shaft of the gear train is connected to the input end of an electrically operated clutch. The output shaft of the clutch is connected to the first end of one of the arms such that upon the simultaneous engagement of the clutch and the energizing of the motor, that arm will be rotated about the horizontal axis at the first end and will cause the door to be opened or closed.
