Abstract: A delay circuit includes a memory (4) addresses of which is designated by a counter (6) incremented in response to each clock signal from an initial value set by an initial value setting circuit (7) to an end value. A digital signal is written into an address as designated and read and converted into an analog signal to be outputted at an output terminal through a buffer amplifier (13). A delay time is determined by the writing timing and the reading timing of the digital signal. If the delay time is to be varied in the course of a delaying operation, a further initial value is set in the counter. A control signal for returning the counter to the initial value is generated by a first signal generating circuit (9) when the end value is reached and a setting completion signal is generated by a second signal generating circuit (11) when a setting of the further initial value is completed, and in response to both the signals, a muting signal is generated by a muting signal generating circuit, whereby the buffer amplifier mutes the output signal in response to the muting signal to prevent a noise due to random data from occurring at the output terminal.

Abstract: 2.1 The axle load of the mechanically sprung drive axle of running gear comprising a lift-axle can be described by the spring deflection of the suspension spring and the pressure of the lifting bellows. A previously described device has a signal body which can be displaced axially by the pressure and rotated by the spring deflection. A three-dimensional characteristic diagram is arranged on the signal body and determines for each constellation of rotational position and axial position the position of the one end of ram representing the axle load signal to be obtained. 2.2 In order to simplify the previously described device, the invention proposes the replacement of the three-dimensional characteristic by a two-dimensional contour (20, 21) and the arrangement in the slide (22, 24, 26) of a cylinder unit (24) which can be subjected to the pressure of lift bellows (1), which unit adjusts the slide length in a pressure-dependent manner. As a result, an adjustment of the position as a function of the slide length is superimposed on the adjustment of the position of the end (26) or the ram (22, 24, 26) by the contour (20,21). 2.3 The preferred area of application is vehicle technology. <IMAGE>

Abstract: The invention relates to an offset printing machine having a damping unit and an inking unit which has an ink metering device for adjusting an ink profile, the inking unit and the damping unit having in each case at least one application roller which can be displaced in the contact position relative to a printing forme. In order to produce an ink profile which approximates to running-on and to reduce waste paper, it is proposed that, to produce an ink profile, which approximates to running-on, permanently or temporarily during the inlet of the ink taking place prior to the commencement of printing or during a stoppage or blanket washing process interrupting the running-on process, the application rollers (34) are displaced by a control device (35) into the contact position on the printing forme (32). A corresponding method is also described.

Abstract: The installation for trailer identification in articulated trucks whose power unit is equipped with an antiblocking device serves to signal to the vehicle driver whether the trailer vehicle also has an antiblocking device (10) and whether its cable coupling (9) is correctly coupled. For this purpose, the installation has an electronic, logic switching device (7) in which at least a first and a second signal are processed. The first signal is only produced when the trailer vehicle is present, the second signal is formed in a test line (11, 11') of the trailer antiblocking device (10) by means of a ground potential connection and is stored as an information signal in the switching device (7). When the first signal is present and at the same time the information signal is absent, an information lamp (4) is actuated which indicates to the vehicle driver the absence or an inadequate coupling of a trailer antiblocking device (10). By virtue of the fact that the second signal is produced from a ground potential connection of the test line (11), it is not necessary to install elements in the power supply line (8, 8') for the trailer antiblocking device (10), the power supply and failure rate of which are therefore not unfavourably influenced by the installation. <IMAGE>

Abstract: A multimode ionization source (106) includes a resistive filament (136) aligned with an exit cone orifice (134). The filament generates electrons that bombard molecules near the orifice. In electron impact mode, a pressure regulator (138) selects a low pressure within an ionization chamber (126) and gaseous analyte is injected through a gas inlet (132) and ionized by electron bombardment. In chemical ionization mode, an intermediate pressure of reagent gas is established; electrons ionize the reagent gas. Gaseous analyte is introduced is ionized by the reagent gas through chemical interaction. In thermospray mode, a high pressure is established and heated liquid analyte is introduced into the chamber as a spray which is ionized by ion evaporation; in a thermospray/chemical ionization submode, filament activation supplements ion evaporation. Ions produced in all modes can be directed to a mass analyzer (120) for analysis.

Abstract: An acceleration sensor comprises a tube (14) formed of an electrically-conductive non-magnetic material; a magnetically-permeable element, such as a iron washer (32), proximate with the passage (24); and a sensing mass (34) in the passage (24) comprising a pair of permanent magnets (36) and a spacer (38) whose magnetic permeability increases with increasing temperature, with the magnets (36) being secured to the opposite sides of the spacer (38) so as to place a pair of like magnetic poles in opposition. In operation, the sensing mass (34) interacts with the iron washer (32) so as to be magnetically biased to a first position in the passage (24), while the magnetic-permeability of the spacer (38) and, hence, the magnetic flux generated by the sensing mass (34) adjusts to maintain a nearly constant threshold magnetic bias irrespective of variations in sensor temperature. The sensing mass (34) is displaced in response to acceleration of the housing (12) from its first position in the passage (24) towards a second position therein when such acceleration overcomes the threshold magnetic bias, while the tube (14) itself interacts with the sensing mass (34) to provide magnetic damping therefor. Upon reaching the second position in the tube (14), the sensing mass (34) electrically bridges a pair of contacts (60) to indicate that a threshold level of acceleration has been achieved. An electrical coil (70) is secured proximate with the iron washer (38) which, when energized, reversibly magnetizes the latter, whereby the sensing mass (34) is either repelled to the second position in the tube (14) or more strongly biased towards the first position therein.

Abstract: The disclosed arrangement controls how client data processing systems in a distributed networking environment can efficiently extend files and write into regions of the files previously unoccupied by data. The server data processing system manages the distributed allocation of new file blocks by sending nascent zeros in addition to real bytes that have been requested by the client data processing system. Nascent zeros are logically zero bytes that have never been stored to or written to, and may be outside the current extent of the file. The server determines whether or not this additional range of nascent zeros will be sent to a client depending upon the amount of physical storage available at the server, and whether or not other client data processing systems require access to this range of blocks. Likewise, the client data processing system has the option of writing to this additional range of nascent zeros. By writing to the additional range of nascent zeros, a client data processing system can minimise the network traffic overhead used in sending messages to the server data processing system requesting a range of bytes.

Abstract: In computer-controlled adjustment of grinding machine settings, one single ball screw (8) is operative to move a lower table (5) and an upper table (6), mutually locked together, to a terminal position in which locking engagement is released and the direction of table move­ment reversed. The tables move together from their starting position, as a result of the friction acting there between, to a predetermined upper-table position in which an engagement means (25a) engages and holds the upper table (6). The lower table (5) then continues to move to a position in which reference points located on the tables are spaced at a predetermined distance apart. The tables are then reconnected mechanically by means of the locking device. This procedure enables the entire grinding cycle to be computer-controlled, including the machine-setup operation. The device which locks the tables together comprises excentric shafts (31) jour­naled in the upper table and provided with locking shoulders (35) which engage or grip an elongated straight edge mounted on the lower table on mutually opposite sides of the straight edge. Oblique forces liable to jeopardize grinding accuracy can therewith be avoided. The invention also relates to a computer-con­trolled grinding machine provided with a work head and a center-point tailstock (16, 17) operating in the manner stated.

Abstract: A stopper for deformable containers, comprising a dispensing device in the form of an elastic diaphragm (21) having at least one cross cut forming a self-closing orifice which opens to dispense out a product present within the container as a predetermined pressure is applied to the container from outside, and closes to automatically cut off the delivery of the product on removal of said pressure. 
     The diaphragm (21) is attached permanently and tightly in an irreversible manner to an inner flange (12) of the tubular wall (2) of the stopper intended for engagement with the container and merely laid on, without adhering to, the convex surface (16) of the top wall (1) of the stopper which is connected detachably to the tubular wall (2) and constitutes a temporary covering element. 
     The elastic diaphragm (2) is formed by a molding process performed directly within the stopper cavity using a predetermined metered amount of a thermoplastic elastomer material which is compressed against the inner surfaces of the caity to thereby permanently and tightly attach the edge (20) of the diaphragm (21)to just the flange (12) of the tubular wall (2) and make it detachable from the top wall (1) of the stopper, and then performing at least one through cut in the area corresponding to said top wall of the stopper. 
     The advantage is thus provided of making the stopper and self-closing dispensing device a unitary construction, and forming the elastic diaphragm from a thermoplastic elastomer material.

Abstract: In a memory access controller, request data is received from a selected request source, specifying the mode of access to a main memory (30), and is supplied to a first pipeline (50) in which it is periodically shifted along its stages. A second pipeline (51) is connected to the output stage of the first pipeline if request data at that stage indicates partial-write mode. Store data is also received during full-write or partial-write mode and stored into a source data register (21) and a buffer (22). A first controller (10) receives request data from the input stage of the first pipeline (50) for accessing the memory in a read mode if it indicates read or partial-write mode or accessing it in a write mode if it indicates full-write mode. The first controller (10) further receives request data from the input stage of the second pipeline (51) and accesses the memory (30) in a write mode if it indicates partial-write mode. A second controller (31) examines request data from all stages of the pipelines (50, 51) to cause data read out of the memory (30) to be supplied to the request source if request data appearing at the output stage of the first pipeline (50) indicates the read mode. The data stored in the source data register (21) is supplied to the memory if request data appearing at the output stage of the first pipeline (50) indicates the full-write mode. If request data appearing at the output stage of the first pipeline indicates the partial-write mode, data read out of the memory and data waiting in the buffer (22) are merged and the second pipeline (51) is enabled to start periodically shifting request data along its stages. When this request data appears at the output stage of the second pipeline, the merged data is applied to the main memory.

Abstract: A method of making a hollow article, for example, a hollow airfoil, from first (10) and second (12) preformed sections involves first forming a precursor fluid impermeable (seal) diffusion bond between opposing bonding surfaces. The precursor bond is formed by subjecting the assembled sections to coordinated pressure-time-temperature conditions where a first high external pressure is applied to reduce any gaps between the opposing bonding surfaces (P) and then a second lower external pressure is applied to actually form the precursor diffusion bond with only limited distortion of one of the sections and no distortion of the other section. In a second step of the method, the precursor bonded sections are subjected to coordinated pressure-time-temperature conditions where a high external and high internal pressure are utilized to form a complete parent metal diffusion bond between the bonding surfaces without distortion of either section. An inflation step may be conducted concurrently or subsequently to the second diffusion bonding step where, during the inflation step, a high external and high internal pressure are utilized to remove any limited distortion of the affected section.
