Abstract: A forensic sample and tracking system includes a computer system (11) which operates a data base (25) and a read/write station (15). The assignment of an identifier in the data base (15) and an identification code to be printed on a sample bottle label (51) are coordinated by the computer (11). An identification code can then be read for verification after it is written. This permits automated verifying of identification codes in a heretofore unavailable manner. The read/write station (15) makes use of an inexpensive, reliable and compact thermal ink jet print head (39) so that a field computer (26) and read/write station (21) can be taken to sample collection sites.

Abstract: This variable speed drive comprises two elements (1, 2) - driven and driving respectively - mounted so as to rotate about two parallel axes, one of which can be displaced relative to the other. These elements are connected to each other by unidirectional coupling members, each consisting of a block (16) capable of being jammed over a circular track (17), or in a likewise circular groove, provided on one of the rotary transmission elements (2). This block is mounted in articulated fashion on a slide (18) which is itself mounted slidably in a diametral slot or groove (19) formed in the other rotary transmission element (1). The arrangement is such that, under the effect of the rotation of the driving element, the coupling blocks (16) assume one after the other, in turns, a jamming position. By modifying the off-centring of the axes of the two rotary elements (1 and 2), it is possible to vary the mechanical transmission ratio continuously. This variable speed drive can be used in numerous mechanical force-transmission devices, in particular on bicycles, motor-driven vehicles, machines etc. <IMAGE>

Abstract: Roll hearth heat-treating furnace, especially one suitable for small metal and ceramic parts. …<??>The exchange of rolls, which are mounted in the side walls, leads to difficulties in known roll hearth heat-treating furnace constructions in the case of narrow separation. Due to the carrying capacity, the roll diameter cannot be selected as small as required either. …<??>It is thus envisaged that the roll bed be constructed of roll table components which each consist of a number of rolls with very small diameters and of two bearing beams which receive the ends of these rolls. By means of this arrangement, the bearing of the rolls is independent of the side walls, because the rolls are received in separate bearing beams which, together with the rolls, form modular elements for the production of the roll bed. …<??>Use for roll hearth heat-treating furnaces for the treatment of small parts. …<IMAGE>…

Abstract: Die bisher als Haftvermittler weitgehend eingesetzten "Tetrasulfane" haben den Nachteil, daß sie hochdispersen Kieselsäuren in erheblichen Mengen zugesetzt werden müssen, um zu Vulkanisaten mit guten gummitechnologischen Eigenschaften zu führen. Außerdem ist die Herstellung dieser Haftvermittler nicht unproblematisch. Die erfindungsgemäßen Haftvermittler führen bei niedrigerer Dosierung als die "Tetrasulfane" unter Verwendung der in der Kautschukverarbeitung üblichen Zusatzstoffen zu vergleichbaren gummitechnologischen Werten, beim Einsatz gleicher Mengen werden teilweise bessere gummitechnologische Ergebnisse erzielt. Hergestellt werden diese Haftvermittler auf sicherheitstechnisch weniger anspruchsvollem Wege. Eingearbeitet werden die erfindungsgemäßen Haftvermittler in helle oder farbige Vulkanisate.

Abstract: The invention relates to an electric heteropolar machine rotor that is premagnetisable by a homopolar magnetic field. The field weakening effect is optimised in that the rotor is divided on the inside into predominantly radially directed magnetic flux paths (5, 10, 18), in which induced and homopolar magnetic fluxes (arrows 7 and 6) extend superimposed on one another in parallel and the magnetic flux paths (5, 10, 18) constructed preferably with parallel edges are provided with such cross-sections that, due to the induced magnetic fluxes (arrows 7) alone, they are already solely magnetised to the onset of saturation. <IMAGE>

Abstract: A fittable pipette tip consists of a vessel which is designed to fit a particularly conical fitting head of a pipette and which may be conical and has a fitting top opening and a bottom opening for receiving and discharging a pipette. A sealing portion with which the pipette tip is adapted to contact the fitting head is spaced from the top end of the pipette tip and is formed with a smooth inside seating surface and has a smaller wall thickness than other portions of the pipette tip so that the sealing portion of the pipette tip is yieldable for adaptation to the fitting head. The pipette tip is reduced in wall thickness at least in the sealing portion by a provision of recesses in the outside and inside surfaces of the wall of the pipette tip.

Abstract: In a multi-processing computer system including a plurality of central processing units (CPUs) and input/output (I/O) units, a system memory including a plurality of independently accessible DRAM-based memory units, and a system control unit (SCU) for operating the CPUs in a parallel fashion and allowing the CPUs and other system units to controllably access addressable segments of memory, dedicated interface means are provided for regulating the transfer of memory commands and associated data between the SCU and the various addressable segments comprising the main memory. The interfacing action is provided by accepting memory commands from the appropriate logic portion of the SCU, processing the commands to determine the availability of addressed memory segments, relaying executable memory commands, at synchronized intervals, to the segments of memory which need to be accessed, and transferring data, in the appropriate direction, as required by the memory commands. The dedicated interface is based on a modular macrocell-based array control unit (ACU) which processes memory commands from the system processors and other units by regulating timed addressing of valid memory segments and bi-directional on-the-fly data transfer to and from addressed segments in main memory under the control of command signals passing to and from the ACU.

Abstract: A furnace for producing oxides of lead includes an enclosure defining a furnace chamber, a feed inlet for feeding particulate lead into the chamber, and a discharge outlet for discharging the particulate lead outside the chamber. An array of horizontally disposed serially communicating tubes are arranged vertically within the chamber, communicating between the feed inlet and the discharge outlet. A rotating valve is associated with the feed inlet, for continuously feeding particulate lead into the number of tubes. Variable drive chain and sprocket combinations are associated with each of the tubes to convey the particulate lead serially along the tubes. The furnace includes electric heat tapes surrounding the tubes, for heating the particulate lead within the tubes while the lead is being conveyed along the tubes. The furnace can be used to produce red lead from leady-oxide or litharge by first supplying air or pure oxygen into the tubes. Leady-oxide is supplied at feed inlet and heated in the first tube to 1250°F to initiate the exothermic conversion of leady-oxide to litharge. Heat from the exothermic reaction occurring in the remaining tubes of the array is used to pre-heat the first tube. Litharge formed from the exothermic reaction is exposed to a lower temperature of 850° in the lowermost tubes of the array for formation of red lead. The travel rate of the litharge determines the percentage of red lead in the final product exiting the discharge outlet.

Abstract: During an active phase of operation of the circuit (70), a gate (38) of a transistor (14) is boosted to a first voltage level that is substantially above the voltage supply level (V dd ). After the gate (38) is boosted, the signal node (12) is boosted by transmitting current through the current path of the transistor (14) from a first electrode (16) of a boosting capacitor (18). During a reset phase of operation of the circuit (70), a second electrode (26) of the capacitor (18) is discharged. This causes the withdrawal of charge from the signal node (12) through the current path of the transistor (14) to the first electrode (16) of the boosting capacitor (18). A predetermined voltage level near the voltage supply level is established across the electrodes (16, 26) of the boosting capacitor (18) in response to this. Finally, the transistor gate (38) is discharged to isolate the boosting capacitor (18) from the node (12), such that the desired voltage level is maintained across the boosting capacitor (18) for an extended length of time.
