In the shield body are arranged a cutter head for excavating the face, a mechanism for rotating the cutter head and a plurality of position-maintaining mechanisms making the natural ground a reaction body to advance the shield body and having press bodies capable of projecting outward of the shield body. The machine, during the excavation has the head portion advanced relative to the tail portion by the thrusting jack and the tail portion next attracted to the head portion by the thrusting jack.

Abstract: An air dryer unit includes an air storage tank including an elongated hollow body of a one-piece construction having a partition wall disposed therewithin to divide the interior of the tank body into a first chamber and a second chamber in an air-tight manner. The second chamber has an outlet connectable to a pneumatic circuit. An opening is formed through that portion of the tank body defining the first chamber. An air dryer device includes a dryer including a tubular housing containing a desiccant and extending through the opening into the first chamber, and a hollow cover member detachably coupled to the dryer housing to cover that portion of the dryer housing extending outwardly through the opening. The cover member is detachably coupled to outer surface of the tank body and has an inlet connectable to an air compressor. One end of the dryer housing disposed in the first chamber communicates with the first chamber while the other end communicates with the cover member.

Abstract: A pull-type pneumatic booster comprises an elongated plunger received in a body for sliding movement along an axis thereof. A movable member is slidably received in the body and defines a low and a high pressure chamber therein. The high pressure chamber is controlled by a valve device to communicate with either of the low pressure chamber and a high pressure source in accordance with the movement of the plunger. One end portion of the plunger extends beyond the movable member into the low pressure chamber. The plunger has the other end portion of a tubular configuration. The front and rear end portions of the plunger are snugly fitted in and disposed in sliding contact with an inner surface of a tubular portion the movable member for guiding the movement of the plunger along the axis of the body. A load-transmitting means is received in the tubular rear end portion of the plunger for transmitting a reaction force applied to the output member to the input member via the plunger.

Abstract: A penile implant includes a hollow elastomeric internal cylinder that is coaxial with an external cylinder both of which are rounded at the distal end and suitably secured to one another at this location. The space between the cylinders is designed to receive fluid through a laterally extending port for pressurizing the implant to achieve the erectile state. A root section is adapted to be fastened to the proximal end of the outer cylinder.When it is desired to implant the prosthesis, the root section is disassociated from the coaxial cylinders and a tool, in rod form, is inserted into the internal cylinder for facilitating the placement of the prosthesis into the dilated corpus cavernosum. When the distal end of the prosthesis is properly located, the surgeon holds the distal end of the prosthesis through the wall of the penis and then removes the tool from the internal cylinder.

Abstract: Piles of sheets (S5) consisting of sheets of security papers (10), which comprise security paper imprints arranged in the form of a matrix, are cut automatically, with step-wise feed, first of all into layers of strips (18) and then into bundles of security papers (19). The lengths of the feed movements of the feed device (26), which moves the piles of sheets forwards step-wise when cutting strips, are controlled by a reading unit (28) provided on the strip-cutting unit (27), respectively on reading an edge mark, which was printed during printing of the sheets in the printing machine (20) by the printing plate on a side edge of the sheet cut off at a later time and orientated parallel to the feed direction of the pile of sheets, when cutting strips.

Abstract: A seam for joining the ends of a fabric to form an endless belt which can be used for papermaking, is created by attaching a continuous coil to each fabric end, the loops of the coils being preformed so that when the loops are intermeshed each loop of one coil engages or creates an interference fit, with two loops of the opposite coil. To strengthen the seam, a pin is inserted in the tube formed by the intermeshed loops.The loops are joined by using a tool which has two channels through which the ends are brought together. The channels are formed between two plates attached to the ends of scissor arms.
