Abstract: A mechanism for clamping a tool (e.g. a probe) and a shank together comprises a clamping pin (144), which bears against an annular lip (142) in the rear face of the probe. A shaft (148) of the pin (144) extends into the shank (150), and two diametrically opposite, radially extending clamping bolts (160) supported by the shank (150), bear against a frusto-conical clamping surface (158). The action of the bolts (160) on the surfaces (158) urges the probe and shank together. The probe and shank are adjusted laterally relative to each other by four adjusting bolts (166) supported in the annular lip (142) which bear against a flange (152). The flange (152) is provided on the shank (150) and extends into the probe (140).

Abstract: A removable tape cartridge (14) for insertion into a carrier (12) in order to form a two-piece videocassette (10) comprises a housing (30) with a tape reel assembly (32) therein. The tape reel assembly (32) includes a length of tape (64) with a connector (68) at one end which, upon insertion of the cartridge (14), mates with an associated connector (16) in the carrier (12) to establish connection with a take-up reel (20). The tape reel assembly (32) is normally biased downwardly by a spring (56) and is normally constrained against rotation by an internal brake assembly (70-74) responsive to insertion of the cartridge (14) into the carrier (12). The tape connector (68) is releasably secured in proper position for mating engagement with the corresponding connector (16) by one end of an arm (78), the other end of which functions to interlock the tape cartridge (14) and carrier (12) against separation upon withdrawal of the tape.

Abstract: A scalable and relatively easily manufacturable heterojunction bipolar transistor (HBT) comprises a thin (exemplarily 5-25 nm) emitter layer (15) that serves as an etch stop layer and that furthermore passivates the extrinsic base region. The portion of the emitter layer that overlies the extrinsic base region is essentially fully depleted at all bias voltages in the normal operating range of the transistor. Base contact is established through the emitter layer, exemplarily by means of a metallized region (16) on the emitter layer. A novel technique for carbon doping is also disclosed. Use of the novel technique makes possible a further embodiment of the inventive HBT, wherein base contact is made by means of Be implantation into the emitter layer.

Abstract: A method of operating data processing apparatus whereby a programmer or user enters both application code and windowing directives, the latter being expressed in natural language. A parser analyzes such input and produces, in response to the directives, one or more case frames defining various functions and associated parameters. A translator converts the case frames into the specific programming language used by the windowing system, and combines such code with the application code. The result is then converted into machine code in order to run the application program on the window system.

IPC: G06F3/038

Abstract: A pen-down sense switch for electronic styli is based on three geometric principles. The first is that a regular convex surface contacts any other surface possessing a larger (or a relative negative) radius of curvature at a single point. The second principle is that rigid bodies may be translated (within limits) without changing their size or shape. The third is that given a plane with a constant radius of curvature, three points which can contact its surface will uniquely determine its position. Within the physical environment and subject to the forces which typically act on stylus switches, machined, solid metal components can be made to be a better than first-order approximation to ideal geometric objects.

Abstract: A vented cap (14) and capillary tube (12) assembly is disclosed together with a method of use of such assembly. The assembly includes a capillary tube (12) having a bore extending therethrough and a cap (14) slidably mounted to one end of the tube. The cap includes one or more vent grooves (20) therein which allow air to escape therethrough when the cap (14) is in a first slidable position. The walls of the capillary tube prevent air from escaping through the vent (20) when the cap (14) is more fully inserted within the tube (12). The method provided herein includes the steps of providing such a pre-assembled capillary tube (12) and vented cap (14) assembly, maintaining the cap (14) in the first position while the opposite end of the capillary tube (12) is inserted within a liquid sample, allowing the liquid to enter the tube through capillary action, thereby displacing air within the tube through the vent (20), and sliding the cap (14) to the fully inserted position, thereby sealing the vent (20). The cap (14) used in conjunction with the capillary tube is made of an elastomeric material, and has a slippery surface. It includes an enlarged head (16) having a cylindrical plug (18) extending therefrom. The plug (18) includes a sealing ring (24) for engaging the inner wall of the capillary tube (12). It also includes an annular groove (22) adjacent the enlarged head (16) which facilitates the seating of the head (16) on the end of the capillary tube (12).

Abstract: Method for monitoring the transportation of goods to predetermined removal stations by means of transport vehicles within a spatially extended region, for example a state, with automatic determination of the distance travelled in each case and detection of this distance in an on-board computer. In a monitoring station, an individual route, containing removal stations, is stored as tour schedule with regard to the relevant route segments, travelling and standstill times for each transport vehicle in a central computer, which schedule is transmitted to the respective on-board computer, stored in it as nominal tour and compared with the actual values forming the actual tour, which are determined as actual route segments and actual times by means of the travel of the transport vehicle and a clock, a difference value being determined from the continuous comparison of the nominal values of the nominal tour with the actual values, which difference value, when a particular limit value is exceeded, conveys to the central computer via a radio data link between the transport vehicle and central station a limit value signal which contains the location established in the transport vehicle and the relevant time, whereupon the central computer, using the relevant tour schedule as a basis, modifies the latter into a replacement tour schedule and transmits it via the radio data link to the on-board computer, which replacement tour schedule is monitored with respect to nominal and actual values in the same manner as the original tour schedule. <IMAGE>
