Abstract: The present invention pertains a replacement liner (10) for insertion in a conveyor pan (100) of a chain type conveyor (200), comprising a floor part (12) having a left connection surface (14) and a right connection surface (16), a left side part (18) having a left side part connection surface (20) connectable to the left connection surface (14), and a right side part (22) having a right side part connection surface (24) connectable to the right connection surface (16). The connection surfaces (14, 20, 16, 24) are configured to form, in a connected state, a form-fitted connection with their complementary connection surface (14, 20; 16, 24). The present invention further pertains to a conveyor pan (100), a chain type conveyor (200) comprising such, a liner replacement method and a liner sheet.

Abstract: A sprocket adapted to be used in a drive unit of a chain conveyor for underground mining applications is disclosed. The sprocket may have a cylindrical body. The cylindrical body may have a front face, an axis of rotation (A-A?), and a lateral surface. The sprocket may also have a scraping member provided on the front face. The scraping member may scrape off deposits during rotation of the sprocket.

Abstract: A marker insertion apparatus automatically removes a marker from a roll of marker material and applies the marker to an applicator. The markers mount to a backing sheet and are peeled from the sheet by passing over a peel bar. Jaws are positioned near the peel bar and configured for gripping an end marker. An applicator member inserts intermediate the jaws and has the end marker pressed onto the applicator and torn from the roll. In a first embodiment, the applicator is a paddle applicator for inserting markers between opposing pages, and in a second embodiment the applicator is a bayonet applicator for inserting markers into the spine of a book.

Abstract: The present re/desensitizer is an apparatus for changing the status of a magnetic marker of an electronic article surveillance system. The markers are attached to or otherwise associated with an object to be protected, such has a book, CD, etc. The device can be set up as a resensitizer, a desensitizer, or with the inclusion of a mode switch, a combination re/desensitizer. The apparatus includes a magnetic field generator for generating a marker status changing magnetic field, detection means for detecting presence of an object, a control means for controlling the activation time of the magnetic field generator such that the marker status changing magnetic field is generated when an object is present. The magnetic field generator includes an offset core designed for continuous operation without excessive heat build up.

Abstract: The repair of holes in walls constructed of plaster core wallboard accomplished by installing clips around the periphery of the holes to retain patches as plaster is being applied. The clips having points pressed into the back surface of the wallboard at a distance from the edge of the holes determined by positioning lugs and patch locating lugs which project into the holes to position the patches in relation to the front surface of the wallboard.

Abstract: A swinging gate operating mechanism having a crank and links which withdraw and insert the locking bolt as the linkages pass over center, and aligning linkage centers to allow the mechanism to rotate freely with a pair of indexing links to prevent the gate from rebounding out of the latch as the bolt impacts the jam post.

Abstract: A device to aid in the tying of dental floss having a compartment to retain the dental floss which can be withdrawn, doubled back, wound around a conical member, passed through a groove and slot and threaded back through, and slipped off of the conical member forming a convenient loop used to more easily floss the teeth.

Abstract: A specialized lock picking set for opening lever tumbler locks. The set consists of a special pick and tension wrench. The pick lifts all the levers simultaneously to allow the bolt stop to move into the lever tumbler gates as the tension wrench exerts pressure on the bolt in the unlock direction.

Abstract: A hydraulic cushioning device, hereinafter called cushion device, improvement in which a spring loaded piston, with an axial orifice, is slidably installed in the expansion chamber, and when return pressure from a hydraulic actuator, hereinafter called actuator is routed to the expansion chamber, by the cushion device, the piston, responding to this pressure moves slowly compressing a spring until it hits a stop at which time the remaining fluid from the actuator must pass through the cushion device restriction thus slowing the actuator rod speed and as the actuator bottoms the cushion device will cease routing actuator fluid under pressure to the expansion chamber and will open the expansion chamber to drain at which time the spring, in the expansion chamber, will force the piston toward the starting end of the expansion chamber, hastening the emptying thereof.

Abstract: A device for cushioning hydraulic actuators at the end of travel including a unique valve responsive to hydraulic pressure which, one when under system return pressure ports fluid to a chamber of less volume than the actuator cylinder and then through a line restriction for reduced fluid flow and the consequential slowing of the actuator and two when system pressure is off, drains the chamber for use during the next cycle.
