Abstract: 1528089 Unloading loose particulate material SCANIAINVENTOR AB 8 Dec 1976 [17 Dec 1975] 51246/76 Headings B8H and B8S Apparatus for unloading loose particulate solid material 38 into a supply 39 includes a supply pipe 10 with positive discharge device 16, illustrated as a conveyer screw 18, driven by a motor 20. As shown in the embodiment illustrated in Fig. 4 the pipe 10 is telescopic and the pressure of material at outlet end 17 is sensed by a diaphragm device 35 to control the vertical positioning of the outlet end 17, to keep the pressure on the conveyer screw relatively constant, through a motor 25 driving a drum 24 on which is wound a hoist rope 23 attached to a beam 22. The arrangement results in the material 38 being forced out below the level of the supply 39 so that the material already in the supply 39 acts as a dust trap. In the embodiment shown in Fig. 3 the discharge pipe 10 is mounted on a crane structure being connected at 50 to a feed conveyer 51 pivoted at its opposite end to a gantry crane 52. The pressure of the material at the discharge end of the positive discharge device 16 is sensed by a device sensing the load on the motor 20 driving a conveyer screw 18 as in Fig. 4. The load sensing device controls the positioning of the discharge end 16 of the pipe 10 vertically and/or laterally through motors 25, 25a, 25b, 25c respectively acting to luff the conveyer 51 through rope 53, to drive the gantry crane 52 along rails (not shown), to regulate the angle between the pipe 10 and the conveyer 51 and to slew the upper parts of the apparatus through a turntable 56.

Abstract: A screen printing machine has a conveyor which is preferably an endless conveyor belt (2) for conveying a material (3) to be printed, the conveyor being drivable over a printing table in a manner such that the belt (2) can be stopped in a first position for registering the material (3), e.g. by front stops 8, 9 and side lays 6, 7, whilst pressurised air is applied beneath the material, and then driven to convey the material (3) to a printing position (3'). Subsequently to the material (3) being registered in the first position the friction between the material (3) and the conveyor is increased by subjecting the undersurface of the material (3) to a negative pressure which is maintained during the conveyance of the material to the printing position (3'). The printing table is conveniently divided into sections of limited longitudinal and lateral extent. Means can then be provided for controlling those sections at which the negative pressure is created during transportation of the material (3) so that only in those sections on which the material sits is a negative pressure created. <IMAGE>

Abstract: An opto-electronic focussing-error detection arrangement is described for the detection of a deviation between a radiation reflecting surface and the plane of focussing of an objective system. In the path of the beam which is reflected by the surface a beam-splitting element is disposed and behind said element two radiation-sensitive detectors are arranged which are each associated with one of the subbeams formed by the beam-splitting element. The detectors are grating-shaped detectors and are effectively divided into two detector sections by selection devices, the bounding line being adjustable. A focussing error signal is obtained which is highly independent of a positional error of the radiation-sensitive detection system relative to the beam axis.

Abstract: A coin detecting device is described comprising a coin chute of the gravity type defining a path down which a coin travels, a delayed-reset microswitch having an actuating arm which is tripped by the passage of the coin down the path, and a plurality of unidirectional coin passing gates located along the path for preventing a cheating operation known as stringing. Stringing involves dropping a coin with a string attached past such a detecting device and manipulating the coin with the string in a manner to make it appear that several coins have passed. The coin detecting device is effective in preventing stringing with coins having slotted and unslotted bodies.

Abstract: Fastener assemblies for mounting a workpiece such as a hub centered wheel rim include a threaded fastener and a clamp washer. The fastener includes a body having a thread structure and a structure engageable by a tool for tightening of a threaded joint to urge the fastener assembly against the workpiece. The clamp washer includes a central aperture surrounding the thread structure and interposed between the fastener body and the workpiece. A pair of cooperating bearing surfaces are formed on the inner end of the workpiece and the outer side of the clamp washer, and a clamp surface is defined on the inner side of the clamp washer. When the fastener assembly is tightened against the workpiece, the bearing surfaces comprise continuous annular spherical zones having common centers and radii of curvature to the end that the bearing surfaces are in intimate wide area face-to-face contact and the clamp surface is in flat area contact with the workpiece regardless of the squareness condition of the threaded joint. The clamp washer may be resiliently deformable during tightening and the clamp surface may initially be of a truncated cone shape in initial circular line contact at its outer periphery with the workpiece. The clamp washer bearing surface may initially be in circular line contact only with the fastener body bearing surface to prevent rotation of the clamp washer against the workpiece. A body of low friction plastic material may be interposed between the bearing surfaces to prevent large frictional forces at the bearing surfaces, and the clamp surface may be scored or roughened to prevent low friction forces at the workpiece.

Abstract: A reversible feeder shoe and door system for the magazine of a staple driving tool enabling set-up of the tool for right or left handed loading. The tool magazine comprises an elongated rail terminating at its forward end at the guide body of the tool. A row of staples is slidably mounted in straddling fashion on the rail. A feeder shoe, having a substantially symmetrical inverted U-shaped body, is slidably mounted on the rail in straddling fashion behind the row of staples. A resilient member constantly urges the feeder shoe forwardly so that the forwardmost staple of the row is located in the guide body drive track. The magazine may include a U-shaped elongated body in which the track is mounted. An elongated door is provided, swingable between an open position exposing the rail top and a closed position overlying the rail top to prevent inadvertent dislodgement of the staples from the rail. The feeder shoe has an operating handle extending laterally from one of its sides and a lug extending laterally from the other of its sides. When the shoe is shifted to its rearwardmost position on the rail by the operating handle, the lug engages a portion of the door, opening the door and releasibly locking the door in its open position, the feeder shoe being also releasibly locked in its rearwardmost position for loading. The feeder shoe is reversible on the rail so that its operating handle can be grasped by the left or right hand of the operator. The door is reversible, being mountable in parallel spaced relationship to either side of the rail.

Abstract: A continuous press is provided wherein the elastic forces are conducted centrically from the centering bolts into the vertical Y-Y axis and the longitudinal center of the guide chain. An accumulation of unilateral forces on the brackets of the guide chain is thereby avoided. The elastic forces, which are set up in the bearing bolts by the linear displacements of the rolling bars and are at times considerable, are thus conducted centrically into the guide sleeves and thus as a force centrically into the guide chain. The forces thus do not occur as an eccentric load on the guide chains and, consequently, are incapable of causing the destruction of the guide chains even with a relatively high load.
