Abstract: A sheet feeder includes a feed roller and pressure rollers for feeding a sheet of paper through the nips each between the feed roller and one of the pressure rollers. The feeder also includes a sheet passage for feeding a sheet of paper through it with an edge of the sheet guided along a side edge of the passage. Each of the pressure rollers is urged against the feed roller by an urging member. The guide edge of the passage is spaced from the adjacent end of the feed roller. Fitted between the edge and the end is a detector for detecting the presence of a sheet of paper. The urging member nearest to the guide edge of the passage is greater in urging force than any other urging member. Therefore, the feeder can feed a sheet of paper without inclining it.

Abstract: An apparatus has a main conveyor and feed conveyors. The main conveyor is provided with elongate receiving elements that are arranged transversely with respect to their movement path. At feed locations, the circulatory paths of the feed conveyors run over the main conveyor. The feed conveyors have clamps that are spaced apart one behind the other and are driven in circulation in a feed direction. The clamps are adapted to feed the products to the receiving elements and to discharge them to these receiving elements at the feed locations. The clamps are arranged obliquely with respect to their circulatory path. As a result, a straight line running parallel to a clamp-mouth plane and a receiving-element plane, and perpendicular to a longitudinal direction of the clamp mouth, forms an acute angle with the circulatory path.

Abstract: A staple sorter comprising a large-capacity non-sort tray. Sheets are stacked one by one on a plurality of bins so as to make collated sets of sheets (sort mode), and each set is stapled by a staple unit. A sheet conveyer gate has rollers and is capable of moving vertically. The sheet conveyer gate takes a stapled stack of sheets out of a bin with the rollers when lowered, and ejects the stack onto the non-sort tray after elevated. When ejecting, the gate is elevated to a position which is higher than the uppermost surface of the sheets stacked on the non-sort tray.

Abstract: When a pick-up roller is lowered to contact with a sheet, a control means stops a tray drive motor to prohibit a lifting movement of a sheet stacking tray to thereby minimize bounding of the pick-up roller when the pick-up roller abuts against the sheet and preventing delay in sheet supply and occurrence of sheet jam.

A one piece unit with an opening at one end only, therefore reducing the sports balls exposure, to ball depleting weather, and offers security, by allowing the open end to be locked by a transverse rod across the open end. Balls are contained in storage unit by protrusions located internally, at the open end, positioned at the greatest apex of the ball allowing sports balls to be completely enclosed within the storage unit. Protrusions hold the ball at a distal position within storage unit allowing balls to be loaded and unloaded easily with a single hand.

Abstract: An apparatus for detecting the passage of superposed sheets, e.g. currency notes, along a feed path (76) includes a mechanism which has a pair of cooperating rollers (12, 14) and which is arranged to generate an output voltage whose magnitude varies in response to the passage of an item (single or multiple sheet) between the rollers (12, 14). This output voltage is applied to an A/D converter whose outputs are sampled at regular intervals while an item is passing between the rollers (12, 14). A data processing means generates a first digital value representative of the sum of these outputs. From this digital value is subtracted a value representative of the sum of the outputs of the A/D converter over the corresponding part of the cycle of the rollers while no sheet is passing between them. A determination is thereby made as to whether or not said item comprises a single sheet.

Abstract: A system (10) controls the dispensing of valuable commodities, such as beers. The system (10) includes a controller (36), sensors (26, 34), and solenoid-activated valves (24). The dispensing of a commodity begins when an operator identifies himself or herself to the controller (36) after selecting a commodity and quantity. A record of this transaction is recorded in a memory (40) of the controller (36). The controller (36) continues dispensing the selected commodity, determines when the selected quantity has been dispensed, then automatically ceases dispensing the commodity. Reports (178) are generated summarizing dispensing transactions. A variety of operational parameters may be established by a manager. Parameters relevant to the preservation and flow of the commodity, such as temperature and pressure, are monitored, and warnings annunciated (164, 170) if out-of-range conditions are detected.

Abstract: A load zone area of a conveyor system which includes a continuous belt which carries bulk materials such as stone, ore, grain, etc. to a discharge point where the material leaves the belt as the belt wraps around a head pulley and returns along the under side of the conveyor system to a tail pulley which brings the belt back to a point which it can be loaded again. The load zone area typically has multiple support rollers closely spaced together to minimize the effect of the material impacting the belt which deflects the belt downward, thus creating a gap between the belt and the skirt seal causing leakage.
