Abstract: A perforated multiweb product in the form of a folded display product or insert has a width greater than the width of any single web forming a part thereof. Gutterless joints are used to allow the display to lay flat when opened. Perforations allow the insert to be removably bound within a book or magazine. In several embodiments, the displays have widths exceeding commercially available web widths. Alternatively, two or more webs are combined to yield web printed single or double magazine inserts or displays having an active viewing width in excess of seventy inches.

Abstract: Apparatus for grinding material which enters the grinder in a wet condition and is subject to drying heat at the grinder to leave moisture in the ground material directed for independently material separation so the propelling initially hot gases looses its temperature level before returning to the grinder. A portion of the returning gases carrying ground fine with moisture therein is directed into a bag house to recover the fines and a portion of the drying heat is directed into the bag house to independently maintain a temperature level above the dew point temperature level in the bag house to prevent moisture from plugging the bag house. The apparatus provides two circulation loops, each with its independent moisture control, and a common transport for collecting product from each loop.

A first cover strip is integrally secured to each of the first and second core strips holding the first and second core strips in side by side position. The first cover strip only partially covers the second major planar side of the core and at least partially covers each of the first and second core strips while extending completely across the second major side of the core and the first and second core strips.

Abstract: A method of removing fractional components from earthen material, including processes for removing precious carbon jewels from soil, precious metals from low grade ores, lead pellets from contaminated soil, and free sulphur from coal, is initiated with a pulverizing of the earthen material bearing the fractional component to be removed therefrom. Subsequent process steps vary, but include the washing of the pulverized material and then removing the fractional component through electromagnetic extraction, chemical dissolution and sieving. Since no contaminate is added to the residue remaining after removal of the fractional component, the residue can be returned to the ground from which the original material was obtained without effecting any additional pollution to the ground or water.

Abstract: A hydraulic control system for a gyratory crusher has a hydraulically supported main shaft. An inlet line to the cylinder is provided with a pressure relief valve. When the pressure in the cylinder, e.g. because of a disturbance, exceeds the opening pressure of the relief valve, fluid flows from the cylinder through the pressure relief valve to the lubricating circuit of the crusher and further to the return line. The safety system of the crusher is simple, reliable, and quick.

A hydraulic drive mechanism, including a hydraulic motor and a rotary hydraulic connector, distribution lines and ports, for distributing pressurized hydraulic fluid to the hydraulic motor, is provided for rotating the outer race relative to the eccentric member about the third axis.

Abstract: A condiment mill has a catcher device installed on the bottom thereof opposite the grinder to catch and prevent the dropping of condiment grindings left over after the mill has been used. The catcher device is in the form of a receptacle and cover which is pivotally mounted on the mill. This cover is resiliently urged towards a closed position by a leaf spring and can be manually placed in retention in the closed position.

Abstract: A concrete crusher has cutting shears with a first cutting arm forming an additional arm on one of the jaws of the breaker tongs and a second cutting arm rigidly joined to the frame of the concrete crusher. An hydraulic piston/cylinder unit drives the jaws such that the first cutting arm is in an open position relative to the second cutting arm when the jaws are in an open position.

Abstract: A discharge mechanism for meat-comminuting machine is disclosed, which comprises a housing structure and a discharge rotor. The housing structure defines a discharge chamber adapted to receive meat comminuted by the meat-comminuting machine, through a front mouth of the discharge chamber, and defines a back wall of the discharge chamber and a cylindrical wall thereof. The discharge rotor is arranged to be rotatably driven in the discharge chamber for discharging the comminuted meat from the discharge chamber, through an outlet of the cylindrical wall, via centrifugal force.

Abstract: A security improved credit, debit, pass, or cash card is a colorless and transparent semirigid plastic card member with non reflective faces, with no permanent imprinting on the card member to visually identify an issuer, an owner or a card number, but with temporary identification that can be removed by the owner of the card and can be visually read only when backed by an opaque sheet. The card has a bending line across a face of the card member that is a slit through the card with a hinge of flexible plastic film attached over the slit. The card has an opening cut through the card member to allow a person's finger nail to engage the opening to pull the card from a wallet or to attach the card on a shirt button.

Abstract: A ring binder mechanism has a base plate that may be mounted in a binder or the like and preferably two spring closure mechanisms that each comprise a filing pin and a tube perpendicularly secured to the base plate. A longitudinally sliding and rotary closing bow is mounted in the tube to open and close the mechanism. A pressure spring is mounted between a disk-shaped bulge of the closing bow and a closed end of the robe to generate a closing force in the direction of the filing pin.

Abstract: A modular ice crusher assembly for use in conjunction with an ice storage unit can be easily removed for cleaning or maintenance. Two parallel brackets are used to mount and support the ice crusher below the discharge opening for the ice storage unit. A release mechanism allows the ice crusher to slide relative to the brackets between a first position in which the inlet chute of the ice crusher is in vertical alignment with the opening of the ice storage unit for receiving ice to be chipped, and a second position in which the ice crusher can be removed for cleaning or service. For example, the release mechanism can consist of a series of pins extending laterally outward from the ice crusher housing that slideably engage a corresponding series of inverted L-shaped slots in the brackets. During normal operation, the ice crusher is held in position below the ice storage unit because the pins are supported in the horizontal portions of the slots.

The pressurized fluid propels the marking particles about the periphery of the chamber. The mill further includes a plug cooperable with the nozzle. The plug is in engagement the nozzle when the pressure within the grinding chamber is substantially greater than the pressure at the inlet of the nozzle.
