Abstract: A reciprocating slat conveyor for loading and unloading a bulk cargo from a stationary or movable receptacle includes a plurality of elongate slats arranged side-by-side along the bottom of the receptacle and grouped into three slat sets each set movable along the bottom of the receptacle. The conveyor includes three cross members each attached to a respective slat set. The cross members and slats are moved by a slat drive which simultaneously moves all slats and cross members in a first direction and then moves the slat sets and cross members in a second direction, opposite the first direction, one cross member and slat set at a time. An angled bulkhead overlies the cross members and drive and shields the member and drive from the contents of the receptacle.

Abstract: A system for indicating whether a hydraulic--pneumatic cushioning unit mounted on a railway car to cushion impacts contains sufficient hydraulic fluid to cushion impacts includes a signal assembly mounted on the body of the cushioning device, the signal assembly unit including a pressure indicator and a signal unit which is removably mounted on the pressure indicator. A cable connects the signal unit to a radio mounted on the railway car. An actuator in the pressure indicator moves when sufficient hydraulic fluid is lost from the cushioning device to impair the ability of the device to cushion shocks. Movement of the actuator operates a switch or load cell in the assembly to send a signal through the cable to the radio which then broad-casts a signal indicating that the cushioning unit is inoperative.

Abstract: A shielded ribbon cable electrical connector assembly includes a shielded cable connector with an overmolded body mounted on the end of the shielded cable and a shielded pin header adapted to be mounted on a circuit board and to mate with the connector. The connector includes a cable clamp on the end of the cable, a premolded connector block containing a row of disconnect terminals and a circuit board forming electrical connections between conductors in the cable and terminals in the connector block. A ground shield plate overlies the circuit board and includes a contact tongue which extends into the cable clamp and is held against the cable shield and a contact finger which overlies the connector block and forms a ground connection with a ground shield on the header. An overmolded plastic body surrounds the cable clamp, circuit board, connector ground shield and part of the connector block.

Abstract: A molding assembly including an elongate crown molding member having a trim mounting groove on the outer surface extending along the bottom of the member opposite a mounting surface on the inner surface, and a trim molding member mounted on the crown molding member in the groove. A fastening member extending from the bottom of the groove through the crown molding member secures the assembly to a vertical wall.

Abstract: A bone or dental cement mixing method and preform body are disclosed. An elongate rod is inserted into a cement mixing chamber. Cement powder is poured into the mixing chamber and around the rod to form a preform body in the chamber. The rod is moved laterally through the powder to form a channel in the body. Cement liquid is poured on top of the body, flows down the channel and is absorbed into the body. The body and liquid are then physically mixed by a conventional cement mixing device to form a cement with cement liquid uniformly distributed throughout the cement.

Abstract: A solid fuel burning stove includes a firebox having front side and rear walls, a top and a bottom, and a secondary combustion unit formed from high temperature insulative refractive material mounted on the top and rear wall of the firebox. The unit is connected to the firebox by a mouth located in the rear wall adjacent the floor of the firebox and by a perforated plate on the firebox top wall. A vertical combustion passage extends from the mouth up to a mixing and combustion chamber located in the unit above the top wall of the firebox. The secondary combustion unit efficiently burns secondary combustion gases flowing into the unit through the mouth and plate during different stages of burning solid fuel, particularly wood.

Abstract: A solder terminal strip stamp formed from thin metal stock includes a carrier strip, a plurality of solder terminals extending to one side of the carrier strip and reverse bend the contact arms on the ends of the terminals away from the strip. A thin solder layer is integrally bonded to contact arm and is joined to solder reservoirs located on the sides of the arms.

Abstract: A reciprocating slat conveyor for loading and unloading a bulk cargo from a stationary or movable receptacle includes a plurality of elongate slats arranged side-by-side along the bottom of the receptacle and grouped into three slat sets each set movable along the bottom of the receptacle. The conveyor includes three cross members each attached to a respective slat set. The cross members and slats are moved by a two-cylinder slat drive which simultaneously moves all slats and cross members in a first direction and then moves the slat sets and cross members in a second direction, opposite the first direction, one cross member and slat set at a time.

Abstract: A system for mixing bone cement is disclosed. Dry PMMA powder and MMA liquid are mixed in a vacuum chamber by a rotary mixer having a pair of spaced mixing arms. The rotary mixer is manually rotated by a gear drive. The arms of the rotary mixer follow continuous paths, each path having a plurality of loops at the wall of the chamber and curved portions extending across the chamber between loops. The arms move through the cement, break bubbles and thoroughly mix the PMMA and MMA. Gas from broken bubbles is vacuum drawn from the mixer by a vacuum source through a vacuum tube which extends between the mixer and a vacuum source. The vacuum source is automatically deactivated when the vacuum tube is detached from the mixer.

Abstract: A concrete beam connector sleeve has a tubular plastic body with a large dimensional end portion, a funnel portion joining the end portion, a rod guide portion joining the funnel portion, a bolting step joining the rod guide portion and a large dimension portion at the end of the sleeve away from the opposite end of the sleeve. The sleeve is cast in a cement column with the large dimension portion opening into a spandrel-supporting recess and the other large dimension portion opening into the opposite side of the column. A threaded rod mounted in a spandrel seated in the recess extends through the interior of the sleeve and past the bolting step. A nut threaded onto the end of the rod secure the spandrel in place on the column.

Abstract: The invention relates to a removable filter for buried catch basins. The filter includes a bag located below grade level in the catch basin and looped flaps which extend above grade level and aid in removal of the filter from the catch basin. The filter is held in place in the basin by a heavy grate which rests on the flaps. The flaps extend at grade level away from the grate. The filter is removed from the catch basin for dumping by inserting a lift rod in each flap loop and hooking lift chains to the rods at openings in the loops.

Abstract: An apparatus and method for winding stiffened coreless rolls which include a spiral wound roll formed from this product paper, conventionally paper having a printed pattern or design on one side, and a spiral stiffener sheet extending completely around the roll to stiffen the roll. The apparatus receives continuous webs of product paper and stiffening paper, severs the stiffening paper into short lengths for winding into the roll of product paper and automatically feeds the stiffening sheet onto a length of product paper which is wound into a roll. The two webs are fed to either side of a continuous rotating cutter roll. Anvil assemblies are moved into engagement with a knife carried on the cutter roll for selectively severing the webs as required.
