Abstract: A first cylinder chamber of a hydraulic cylinder is connected to a pair of variable displacement pumps of which the first one is connected to a reservoir and second one is connected to the second cylinder chamber. This allows to bias the piston by a hydraulic force acting on either side of the piston corresponding to the direction of motion. This is obtained by adjusting the delivery volume of both the pumps such that the volume supplied is larger than the volume drained. Metering the difference of both the delivery volumes results in the desired biasing counter-pressure.

Abstract: The invention refers to a hydraulic system comprising at least a variable displacement pump and at least a consumer. Means are provided to generate electrical limit signals when at least one of the consumers, preferably a load leading consumer indicates the need for an increased delivery rate or when the variable displacement pump indicates a hydraulic under-supply. In response to the limit signals generated by the consumer need or the pump are varied in a control circuit to adjust the control signals delivered to the servo devices of the hydraulic systems such that the pump control is optimized and that the flow rates to the consumers are decreased in the mode of under-supply. In addition very simple electrical circuits are disclosed to substantially reduce the expenditure of the system.

Abstract: A guide member is slidably mounted on a rod, and a resilient seal bag around the rod is secured to the guide member. The rod is inserted in a heat conductive cylinder secured to the guide member, and wax is provided in the heat conductive cylinder. The seal bag has a base portion having an opening, and a bag portion, and is engaged with the rod only at the opening to form a gap between the bag portion and the rod. The gap is charged with lubricating oil. The pressure of the lubricating oil is built up to a value equivalent to the pressure of the wax, thereby holding the bag portion in a floating state. The rod is lifted by the pressure of the lubricating oil.

Abstract: A fluid pump has a rotary pressure generator means rotatingly driven by a power unit, such as an automotive engine, and variable of output pressure depending upon rotation speed of the power unit. The pressurized fluid output from the pressure generator means is supplied to a high pressure chamber which is connected to an external hydraulic device, such as an automotive steering device, via a high pressure path and a supply line. The supply line is connected to a high pressure path via a pressure regulating path. The pressure regulating path is so designed as to provide flow resistance which increases according to increasing of the fluid pressure supplied to the supply line from the high pressure path. This makes pressure variation gradient at the supply line smaller than that in the high pressure path.

Abstract: A fluid-driven working cylinder without a piston rod is provided with a cylinder housing (4) which in cross-section is fully closed, and along which a force takeaway (1) is guided without turning.

The band (7) is externally guided over two reversing wheels. To avoid leaks of the cylinder housing (4) during pressurization the interior of the cylinder housing (4) is divided into a piston space (8), in which the working piston is moved back and forth, and a band space (9), which is separated from piston space (8), but which is connected with the piston space (8) by means of a longitudional slit (10) which is sealed off by a sealing strip (5). Band (7) runs in the band space (9) and is connected to the piston by means of linkage (6) which projects through the longitudinal slit (10).

Abstract: To ensure accurately aligned handling of a plurality of superposed webs (3, 4) forming a composite web, which is to be folded longitudinally twice, particularly to maintain alignment of the individual folded web portions for subsequent application of indices, month, or other date identification and the like, particularly for book and calendar printing, two longitudinally located folding triangle or formers (22, 40) are located, one immediately behind the other, in the path or stream of flow of the webs, in which the first one receives the webs, after lateral alignment and the like, from the printing machine, and the second one is rotated 90.degree. with respect to the incoming web to the first folding former, and applies a second fold. This ensures that the web is always processed in a linear path without twist or lateral offset, thus ensuring alignment of the individual elements of the composite folded web (8).

Abstract: Printed products are stapled by guiding them between a stapling-head arrangement and a staple-closing arrangement. The stapling-head arrangement comprises a number of stapling heads revolvingly moved along a closed revolving path. A section of this closed revolving path thereby extends substantially parallel to the travel path of the printed products. The staple-closing arrangement comprises a number of countersupports likewise moved along a closed revolving path also having a section extending substantially parallel to the travel path of the printed products. A countersupport co-acts in each case with a stapling head to close the respective inserted staple. Consequently, during the stapling operation, the stapling heads and the countersupports run along and cover a certain distance together with the respective printed products to be stapled.

Abstract: The present invention relates to an electrically actuated and controlled auxiliary hydraulic system for controlling the flow of hydraulic fluid under pressure to mounted attachments on a skid steer loader. In one embodiment, an electrically actuated auxiliary control valve is coupled to the front and rear mounted attachments through an electrically actuated diverter valve. In a second embodiment, a front and a rear auxiliary control valve is coupled to the front and rear mounted attachments. An operator can select between control of either the front or rear attachments by selectively actuating the forward, reverse and latch switches on the control handles. A mode control switch electrically coupled to an auxiliary mode control circuit allows the cyclical selection between the disable mode, the momentary mode, and the latch mode. In the disable mode, the actuation of the forward, reverse or latch switches has no effect.

In a second region, the staple is brought onto the side of the stapling heads facing the supports. In a third region, the stapling heads are lowered onto the printed sheets, which are deposited onto the supports, and stapled together.

Therefore, newspapers containing inserts for readers having particular characteristics can be formed and indicia corresponding to addresses along a delivery route printed on the newspapers in a sequence which is the same as the sequence in which the newspapers are delivered to the different addresses along the delivery route. During the forming of the newspapers, collating spaces are moved past hoppers from which inserts are fed. The completed newspapers are transferred from the collating spaces to a discharge conveyor in a sequence which corresponds to the sequence in which newspapers are to be delivered to different addresses along a delivery route.
