Abstract: A flushing means for drilling tools comprises a guide member (10) carrying a drill bit (20) and being rotatably centered by the mouth of a casing tube (11) which is adapted to follow the drilling tool downhole during drilling. The drill bit (20) has a bit portion (22) that projects laterally beyond and is spaced axially in front of the casing tube (11) so as to drill a hole larger than the casing tube (11). There are external flushing grooves (70,71) on the guide member (10) adapted to lead the outflow of flushing medium and debris from the hole during drilling into the casing tube (11). At least one of these grooves (70) extends from front to rear of the guide member (10). One or more further grooves (71) are open towards said rear while ending blindly into the peri­phery of the guide member (10) spaced from its front. By re­traction of the guide member (10) its front enters the casing tube (11). That closes the blind grooves (71) and an intensi­fied flushing is thus possible via the remaining open grooves (70) that extends from front to rear of the guide member (10). The cutting front (40) of the bit portion (22) is flushed rotatively in counter flow to the rotational drilling direc­tion (8) towards the full length groove (70).

Abstract: Items are identified and tracked by attaching radio transceiver tags to the items and sending signals between the tags and one or more interrogation subsystems. The tags are normally in low-power standby mode unless signalled by an interrogator. The interrogator broadcasts a signal to all of the tags within reception range, and the tags respond after pseudo-random delays. When the interrogator has identified a tag, it signals that fact back to the tag and the tag returns to standby mode. The tags that were not identified by the interrogator retransmit their identification signals, and the process continues until all tags within range of the interrogator have been identified.

Abstract: Marks such as patterns, designs, numbers, or the like are cut out of a mark sheet (20) or mark sheets placed on a glass base by a thermal cutter (30) having a heated cutting bit (32). The thermal cutter (30) is movable two-dimensionally over the mark sheet (20), and is also vertically movable between an upper position in which the thermal cutter (30) is lifted off the mark sheet (20) supported on the base and a lower position in which the thermal cutter is lowered in contact with the mark sheet (10) supported on the base. The thermal cutter is angularly movably supported on an eccentric shaft (102) that is rotatable by a stepping motor (112). The thermal cutter (30) has a cutting bit (34) resiliently urged by a spring (118) for stable positioning. A range or ranges in which desired marks are to be cut out of a mark sheet or mark sheets can be confirmed by being traced by the thermal cutter (30) before the marks are actually cut out. When mark numerals indicative of desired numbers are to be cut out, such mark numerals are rearranged and displayed for the operator's information. The thermal cutter can be cleaned by a cutter cleaner (38) in a different cleaning pattern each time the thermal cutter (30) has moved a predetermined distance in contact with the mark sheet (20) or mark sheets. The thermal (30) cutter moves to the cutter cleaner (38) and also to a position to start cutting out desired marks, at a higher speed than the speed at which it cuts out the desired marks.

Abstract: The invention relates to a detecting apparatus with a laser unit for producing a radiation spot on the workpiece surface, with a sensor unit in which the laser light coming from the radiation spot is absorbed via an interposed filter and is imaged on an observation plane inclined relative to the workpiece surface, and with detectors by means of which the image in the observation plane is converted into signals, on the basis of which changes in the distance between the observation plane and the radiation spot can be discovered. With the invention, the proposal is made to arrange two optical waveguide units (16, 17) in the observation plane (14d) in such a way that, with the increase or decrease in the distance in relation to a desired distance, the top or bottom optical waveguide unit (16 or 17) is acted upon by laser light to a greater extent than the other respective optical waveguide unit. For detecting the distance or for adjusting the sensor unit (14), the outputs (16b, 17b) of the optical waveguide units (16, 17) can be changed in such a way that they can be attached either to the detectors (21, 22) or to light-transmissive connecting elements (24) which can be illuminated by means of an adjusting light source (25) which can be switched on separately. The outputs of the detectors (20, 21) are combined via a differential circuit (26) which produces the differential signal DS "zero" if the actual position of the workpiece surface (2a) coincides with its desired position. <IMAGE>

Abstract: The apparatus for cyclically actuating an actuation member has a hollow shaft (12) rotatable about an axis (14) of rotation and having a cam opening (34) therethrough, an inner shaft (16) rotatably carried within the hollow shaft, camlobe members (36 and 28), respectively fixed to the hollow shaft (12) adjacent the cam opening (34) and to the inner shaft and projecting through the cam opening (34). A variable transmission (38) has a reference element (40, 42) connected to one of the shafts (12), an output element (52, 54) connected to the other of the shafts (16), and an input element (58); a pulley wheel (50) is connected to the shafts for rotating same about the axis (14), and an electric motor (72) is drivingly connected to the input element (58), and is controlled by an electronic control unit (84) which can include one or more microprocessor units. The apparatus can be utilized to actuate and deactuate one or both of the intake valve and exhaust valve of an internal combustion engine. 
     A method of attaining a desired engine performance comprises the steps of changing the angular position of a variable camlobe (or cam) member (28) relative to a fixed camlobe (or cam) member (36) from a first angular position to a second angular position, by a movement of the former in a predetermined direction relative to the direction of rotation of a camshaft. The predetermined direction and the magnitude of the angular movement of the variable camlobe (or cam) member (28) is dependent at least in part upon at least one desired operating condition of the engine. Both camlobe (or cam) members (28, 36) may be moved relative to a reference point of a drive pulley. 
     A method is provided for reducing pumping losses in an internal combustion engine, comprising the steps of inducting a charge of fluid into the engine's combustion chamber, holding the intake valve of the combustion chamber open during a portion of the compression stroke of the piston in the combustion chamber, expelling a portion of the inducted charge from the combustion chamber by movement of the piston in its compression stroke while the intake valve is held open, preventing the expelled portion of the inducted charge from communicating with the atmosphere by a check valve between the induction manifold and the atmosphere, and closing the intake valve during the remainder of the compression stroke and after the portion of the induction charge is expelled.

Abstract: A rim-fitted tire with a weight unbalance corrected in which a plurality of balance weights for correcting static unbalance are attached on an outer peripheral surface of the rim thereof at a substantially central position with respect to the widthwise dimension of the rim. Balance weights (W₁, W₂) are attached at widthwise opposite ends of the rim to correct an amount of static unbalance on the basis of an amount of dynamic unbalance measured in the static-unbalance corrected state. Since the balance weights are attached on the rim in a distributed manner, the weight of each balance weight is made light, thereby reducing the centrifugal force occurring when the tire is actually used on a vehicle.
