    摘要: A system for automatically adjusting the print head gap of an impact printer, particularly for paper stocks of differing thicknesses and multi-layer forms, provides for measurement of an absolute distance between an undeflected platen position and a home position of the print head. Paper stock thickness is measured by measuring the distance to the home position from a position of the print head when a predetermined force is exerted by the print head against the platen. Since a similar measurement is made when paper stock is not present in the printer and using the same force against the platen, platen flexure is removed as a source of error and a standardized force is available for compression of the paper stock during measurement. Improved accuracy is achieved at high speed while avoiding the use of position encoder/decoder arrangements. A wider range of manufacturing variations in printer geometry and rigidity can be accommodated with uniformly improved print quality.

    摘要: A vacuum air exhaust system (8) employs a venturi vacuum pump (10) that is fed pressurized air through a control valve unit (18) rigidly mounted on a vacuum pump housing (24) of the vacuum air exhaust system. By manipulating a movable valve of the control valve unit, an operator can control a vacuum applied by the vacuum pump. The vacuum air exhaust system is rigidly attached to a pipe-type mount unit (16) for being rigidly attached to a wall at a hole in the wall so that ventilation suction is applied through the pipe and the wall. In one embodiment the exhaust adapter is attached to a flexible hose (41) and in another embodiment it is rigidly screwed to a pipe (42), such as a filter pipe.

    摘要: An evacuator housing ( 14) of a gas tank evacuator (10) receives a gas tank (12). A valve seal of a movable seal head (34) and a puncture seal (66) of the evacuator housing are clamped onto the gas tank at opposite ends by a hollow threaded shaft (32) to form a sealed test space (58) exteriorly of the gas tank at a valve (22) and a sealed evacuation space (68) exteriorly of the gas tank at a puncture spot (24). A pressure gauge (60) coupled to the test space rides on the seal head and a valve actuator in the form of a rod (40), passes through the hollow threaded shaft into the sealed test space. A puncturing mechanism (18) punctures the gas tank at the puncture spot. The sealed evacuation space is positioned vertically below the puncture spot and communicates with a carbon filter positioned vertically above the evacuation space so as to form a U-shaped trap (90).

    摘要: A puncturing device (10) for pressurized containers (12) comprises an elongated housing member (16) defining an elongated cavity (24) with openings (26, 28) at first and second ends (30, 32) thereof for receiving an inverted pressurized container at the first end, the housing member including a selective attachment member (36) for securing the second end of the housing member to a collection receptacle (38). A non-sparking puncturing apparatus (18), with a lever (44) having a built-in stop (48, 50), is movably mounted on the housing member with a pivot-link (54)-driven puncture pin (56) extending through an intermediate aperture (34) into the cavity for piercing a nozzle-end of the pressurized container below an internal shoulder (40) thereof with a seal (42). Thus, gases and residual contents are released into the receptacle through the opening in the second end. An auxiliary support member (22) is rotatably mounted on the housing member for stabilizing relative movement between the housing member and the receptacle. A force-applying apparatus (20 ) is mounted on the housing member for engaging the pressurized container and holding it on the seal.

    摘要: A gaseous-material evacuation system includes a filter assembly (44) with a housing (56) containing filter material (58) with a downstream porous filter member (60) at a downstream side of the filter material. The filter assembly includes a valve (64) with a movable valve member (66) for moving in a direction of gas flow and having a breadth area dimension that is at least as great as that of the downstream surface of the downstream porous filter member. In a preferred embodiment, a spring member (68) presses the movable valve member (66) against the porous filter member (60), thereby stopping gaseous flow, but yields when gaseous materials are driven through the filter at a predetermined pressure. The valve member is mounted in a sub-compartment (72) of the housing, which is of a single-piece housing member.

    摘要: A gas tank evacuator (10) comprises an evacuator housing (12) into which a neck (80) of a gas tank (82) can be screwed and an elongated valve-removal rod (14) for slidably passing through the evacuator housing and engaging and unscrewing a stem-actuated valve (88) of the gas tank. An elongated valve actuator pin (18) slidably passes through the valve-removal rod to extend from lower and upper ends of the valve-removal rod for independently actuating the stem-actuated valve. The valve-removal rod is moved longitudinally by a valve-removal-rod lever (16) which is pivotally attached to the evacuator housing and valve-removal rod by pivot links (60). The valve-removal-rod lever is pivoted on the evacuator housing to drive a valve-engaging device at a lower end of the valve-removal rod into engagement with the-stem-actuated valve of the gas tank for its removal from the gas tank.
