Abstract: Chip card reader (3) comprising an entry opening (4) for accommodating a chip card (2). An approach is to be demonstrated by means of which the removal of the chip card (2) from the chip card reader (3) is impeded during the reading state. This is done by providing in the area of the entry opening (4) thickenings (9, 10), the free end areas of which point away from boundary areas (5, 6) of the entry opening (4), arranged parallel to one another, and extend spaced apart from these. <IMAGE>

Abstract: The invention relates to a method and/or a device for demodulating a binary coded phase-modulated signal (biphase signal). It is provided to determine the period of time (T) passing between each two successive level jumps of an incoming biphase signal, to generate or extract a clock frequency (B) approximately corresponding to the bit rate of the biphase signal with the aid of a clock generator, the clock period (1/B) of which clock frequency is compared with the period of time (T) between each two level jumps, and to determine the logical value of the biphase signal with the aid of an interrogating circuit controlled by the clock frequency (B), and to output a signal corresponding to the logical value, whenever a value of between 1/4 and 3/4 of 1/B was determined twice in succession for the period of time (T) immediately before, or whenever a value of between 3/4 and 5/4 of 1/B has been determined for the period of time (T) immediately before. In addition, a signal identifying a disturbance can be output or the output can be muted if a value of less than 1/4 of 1/B or greater than 5/4 of 1/B has been determined as the period of time (T). The invention makes it possible to recover the original data with sufficient reliability in a relatively simple manner when a biphase signal is present.

Abstract: Thermoplastic compositions and composites are produced which have fewer and smaller voids with more consistent dimensions compared to conventional unreinforced and fiber reinforced thermoplastics. The high modulus thermoplastic contains silicone semi-interpenetrating polymer networks which are formed by vulcanization within the thermoplastic and initiated during melt processing. Parts molded from the compositions are more homogeneous, with evenly distributed voids, thus reducing the possibility of stress fractures. The compositions are particularly useful in the molding in thick cross-section and variable thickness parts and have been found to have increased thermal stability.

Abstract: A combination weighing apparatus (10) and method are provided particularly adapted for, utilization with difficult to handle product. A series of in-line transfer conveyors (12) form product feed lanes with individual volumetric cups (22) designed to receive and hold a product charge (C). A scale (S) and weighing hopper (38) is associated with each transfer conveyor (12). The transfer conveyors (12) are each advanced in stepped fashion so as to deliver a product charge (C) from one volumetric cup (22) at any single time to the associated weighing hopper (38). A washer unit (40) cleans residue and the product buildup from the cups (22) after delivery of the product charge (C). Once the product charge (C) is delivered to the weighing hopper (38), the weight of the charge is registered by a control unit (44). The control unit (44) scans various combinations of scales (S), calculates the total weight of product in the combination and selects the first combination that falls within an acceptable range above the target weight. The product charges (C) are then delivered in timed relation to a plate (P) as it advances along a conveyor (46) beneath the scale hoppers (38). In accordance with an important aspect of the present invention a feedback mechanism (86,88) is provided for indicating the weight trend of product charges (C) being delivered to the volumetric cups (22). As long as the charge weights fall within a preselected range, the quality of charges from which the control unit (44) selects is maintained at a high level so as to allow maximum operating efficiency.

Abstract: A logic circuit improves a marginal voltage of a p-channel metal oxide semiconductor (MOS) transistor which is driven through a bipolar complementary metal oxide semiconductor (CMOS) gate. The logic circuit has a bipolar CMOS gate (50) having a CMOS gate (51) and output stage bipolar transistors (Tr41, Tr42) for receiving an input signal through the CMOS gate, where the CMOS gate and the output stage bipolar transistors are driven by first and second power source voltages (V CC , V EE ), where the first power source voltage is higher than the second power source voltage and the output stage bipolar transistors output a signal as an output signal of the bipolar CMOS gate, and a p-channel MOS transistor (Q61) having a gate supplied with the output signal of the bipolar CMOS gate, a source supplied with a third power source voltage (V CC ′), and a drain from which an output signal of the logic circuit is outputted. The third power source voltage is a predetermined value lower than the first power source voltage and higher than the second power source voltage, thereby able to guarantee a turning OFF of the p-channel MOS transistor due to the improved marginal voltage.

Abstract: The invention relates to a process for producing epitaxially and/or highly texturally grown, high Tc oxide superconductors fibres, with a low foreign phase on substrates, in which process an ablation process is initiated and maintained on a donor target by means of pulsed particle beams or laser beams and small droplets having diameters in the  mu m range produced in this process reach the heated substrate, and also to an apparatus for carrying out the process. The object of the invention is to replace the EXIMER laser hitherto used for coating by less expensive and more effective lasers or electron beams. According to the invention, the object is achieved in that the substrate is held at a temperature at which the droplets wet the substrate on impact and solidify to form a uniform, smooth film. An apparatus particularly suitable for carrying out this process comprises an electron source which produces a pulsed electron beam with an electron energy of about 10-20 keV and a current density in the range from 10<3> to 10<4> A/cm<2>.

Abstract: A device serves for stacking flat workpieces provided with stacking holes on stacking pins or stacking fingers of an endless flexible conveyor means which runs over deflecting rollers at the ends, or an endless conveyor chain which runs over deflecting chain wheels, which are advanced intermittently by a step after the formation of a stack having a predetermined number of pieces. The device comprises a conveying means for the successive feeding of the workpieces to be stacked and a means for pushing the workpieces onto the stacking pins or stacking fingers. So that stacks can be formed on the stacking pins or stacking fingers without the feeding of the workpieces to be stacked having to be interrupted during the advancing of the conveyor means after formation of a stack, the stacking fingers (9) are arranged on elongate pedestals (12) fixed on the conveyor means (10) or on the conveyor chain, whose width is smaller and whose length is greater than the diameter of the stacking holes. At least one essentially U-shaped supporting piece (18) is provided which forms an intermediate stacking finger, is fixed on a carrier (17) and can be slid in or swivelled in, the profile cross-section of this supporting piece being smaller than the diameter of the stacking holes. In its engagement position, the supporting piece (18) surrounds the stacking finger (9). The height of the supporting piece (18) corresponds approximately to the height of the pedestal (12). The supporting piece (18) is vertically displaceable relative to the pedestal (12) and the stacking finger (9) which forms an upward extension of said pedestal. …<IMAGE>…

Abstract: An ornamental heat activated transfer, which is especially adapted for application to nylon fabrics, includes an upper layer (13,18,23) which is generally a thermoset layer or cloth such as twill or flock and which is bonded to a lower layer (12,15,22). The lower layer (12,15,22) is an uncured linear saturated polyester film which includes a heat activated isocyanate curing agent. Upon application of the transfer to nylon the transfer is heated which melts the uncured saturated polyester and activates the curing agent. Thus while the linear saturated polyester is in a molten state the curing agent causes the polyester to cure in tight confinement with the nylon fabric.
