Abstract: A cutting device includes a body. A mouth is formed in the front end of the body for receiving a pipe to be cut. A cutter is received in the body and is movable toward the mouth. A gear and an upper end of a handle are pivotally coupled to the body. The gear is engaged with the cutter and is caused to rotate when the handle is pulled so that the cutter can be caused to move forward by the rotation of the gear in order to cut the pipe. The pipe can be cut neatly and efficiently when the handle is repeatedly pulled and released.

Abstract: A spoon or other like hand held implement or utensil comprises a spoon bowl (10) or other load carrying formation fixed to an inner stem (12) which also carries a pendulum weight (22). The inner stem rotates freely within a hollow outer stem (24) which is held in the user's hand and which preferably encloses the weight. In this way the spoon or the like can be used in a self-levelling mode; when the bowl is loaded and with the handle stem held horizontally or approaching horizontal the load will be retained despite any lack of mobility or skill or the part of the user (e.g. a blind or disabled person or young child) or disturbance e.g. when used on a moving ship or vehicle. A brake or other locking device (30,32) can be selectively applied to prevent said rotation and the device may also serve to open the outer stem when shifted to another position.

Abstract: A blow-molded notebook binder provides protection from mechanical shock and abuse. When antistatic and/or conductive agents are blended into the polymeric material to make up the parison for the notebook binder, protection from electrostatic discharge is also provided. This invention finds special use in clean room environments.

Abstract: For convenient packaging of plastic bookbinding strips, cassettes are provided. The end edges of each strip are received in channels formed in opposed side rails. The rails engage adjacent either end the depending legs of transverse spacer bars. The spacer bars have plural sockets to engage projections on the upper ends of the legs so that the spacing between side rails may be varied to accommodate strips of different lengths--e.g., 81/2 inches, 11 inches, etc. Different length legs may be used to accommodate different length studs formed on the strips. By eliminating the legs entirely, flat female binding strips may be packaged in the cassette. A detent is provided in the ends of the rails preventing removal of strips until the detent is bent out of position. The cassette is especially useful in equipment which mechanically assembles punched sheets and strips preparatory to binding a book in a binding machine.

Abstract: A card (20) has a recording surface (36) with three aligned horizontal rows (40,42,44) of boxes. The first row (40) is in the middle with the second row (42) above it and the third row (44) below it. An initial odometer reading of a vehicle is recorded in the first row (40). At the same time, a base fuel gauge reading is taken and is recorded by positioning a pivotable pointer (50) mounted on the card (20) above the first row (40). The vehicle is driven to consume fuel, and ten gallons of fuel are added to bring the fuel gauge reading above the base reading. When the fuel gauge again reaches the base reading, a second odometer reading is taken and recorded in the second row (42) of boxes. The reading in the first row (40) is subtracted from the reading in the second row (42), and the result is written in the third row (44) of boxes. A decimal point (46) is positioned between the two rightmost boxes of the third row (44) to automatically convert the subtraction results into miles per gallon.
