Abstract: A door set assembly for use with a door having a latch portion and a magnetized strike plate, comprising a top face, a bottom face, and a protrusion extending below said bottom face of said strike plate. The protrusion is formed by two side walls and a far wall extending from said top face of strike plate and a graded floor angled away from said top face of said strike plate, the combination of said walls and said floors forming a latch receiving channel, such that when the door is swung into the closed position the magnetized strike plate gradually actuates the latch of said latch portion along the entire length of said channel, from a fully retracted position to a fully extended position until said far wall of said strike plate channel holds the latch in place to keep the door in the closed position.

Abstract: Disclosed herein is a sheet feeder for a printer. The sheet feeding device feeds a single sheet into an infeeder of a printer without communicating with the printer. The sheet feeder is equipped with a sensor for detecting when the printer is able to accept a sheet. The sheet feeder is equipped with a programmable timing device that causes the sheet feeder to wait a predetermined amount of time before inserting another sheet into the printer. The predetermined amount of time corresponds to the amount of time needed for the printer to complete printing on a sheet after the sensor has detected that the printer is able to accept a sheet into the infeeder of the printer. The sheet feeder is configured with a gate having an adjustable gap in close proximity to a tray containing a stack of sheets. The gate permits only a single sheet to be fed into the infeeder of the printer at a time. The gate has a guide post having a radius of curvature curving toward the gap to urge the stack of sheets toward the gap in the gate. The sheet feeder has an adjustable tray designed to compensate for non-uniform profiles of a stack of sheets. The adjustable tray urges the stack of sheets into the gap in an upward motion to prevent jamming of the sheets in the sheet feeding device.

Abstract translation: 这里公开了一种用于打印机的片材进给器。 纸张馈送装置将单张纸馈送到打印机的进料器，而不与打印机通信。 送纸器配备有用于检测打印机何时能够接受纸张的传感器。 送纸器配备有可编程定时装置，其使片材进给器在将另一张纸插入打印机之前等待预定的时间量。 预定的时间量对应于在传感器检测到打印机能够将纸张接收到打印机的进料器中之后打印机完成在纸上打印所需的时间量。 片材进给器配置有具有可调节间隙的门，该门可接近包含一叠片材的托盘。 门只允许一张纸一次送入打印机的进纸器。 门具有向间隙弯曲的曲率半径的引导柱，以朝着门的间隙推动片堆。 片材进给器具有可调整的托盘，其设计用于补偿一叠片材的不均匀轮廓。 可调节托盘向上推动片材堆叠到间隙中，以防止片材在片材进给装置中的卡纸。

Abstract: A non-rotating wedge-shaped ink agitator which reciprocates within an ink fountain along the length of an ink fountain roller. The ink agitator has a substantially flat bottom surface, side surfaces extending upwardly and outwardly from the bottom surface and a top surface which slopes toward the end of the agitator adjacent the ink fountain roller.

Abstract: A system for mixing concentrate and water continuously and automatically including a water supply system and a concentrate system which systems feed into a common conduit to mix the concentrate and water to form a fountain solution. The water supply system has a water motor and is interconnected with valves for controlling the flow of water to and from the water motor. The concentrate system includes a concentrate pump and a concentrate supply valve for controlling the flow of concentrate to and from the concentrate pump.The water motor is interconnected with the concentrate pump to thereby drive the concentrate pump and the stroke of the concentrate pump is variable to permit variations in the concentrate and water mixture.The operation of the water system and the concentrate system is controlled by a pneumatic system which is activated by the water motor.
