Abstract: A printer in which a single pinch roller (18) serves the dual function of a pinch roller cooperating with the drive roller (14) to feed paper to the printing zone, and a carriage guide to guide movement of the printhead carriage (20). This roller automatically properly references the printhead to the printing surface, regardless of paper thickness. The printhead carriage (20), which is pivotally mounted to a carriage guide rod (16), rests in contact with and rides along the roller(18). Preferably, the center of gravity of the printhead carriage is spaced from the carriage guide rod and is disposed above the pinch roller, and the pinch roller is spaced from the carriage guide rod, so that the printhead carriage is preloaded into continual contact with the carriage guide rod. The carriage guide rod may be disposed either on the same side of the printhead carriage as the pinch roller, or on the opposite side of the carriage from the pinch roller.

Abstract: The compress contains a depot layer (1) for the storage of fluids. That side of the depot layer (1) which is directed towards the front side of the compress is assigned a control layer (2), which is designed in such a way that the secretion which reaches the latter can spread predominantly along this layer (2) before it reaches the depot layer (1). In order to achieve this effect, channels (3) are made in that surface of the control layer (2) which is directed towards the front side of the compress. These channels (3) extend in the planar direction of the control layer (2). The two layers (1, 2) are arranged between a surface covering (10) and a lower closure layer (15), the edges (16, 17) of which are welded. 
<??>Fluids, which reach the surface layer, spread over the whole area of the compress quickly and uniformly.

Abstract: The functionalisation of rubbers or thermoplastics by means of maleic anhydride (MA) is associated with considerable emission and metering problems which can only be overcome to a limited extent even using conventional MA masterbatches. By contrast, it has now been found that masterbatches of MA and a polystyrene resin are not only easy to prepare by mixing the melts, but are also easy to handle and have a significantly improved emission behaviour due to the homogeneous distribution of the MA. These mixtures are particularly suitable for the functionalisation of polyphenylene ethers or polystyrene.

Abstract: Data input from a key switch (3) is displayed on a liquid crystal display (2), and whether to store the data in a RAM (6) or an EEPROM (7) is selected by a selection switch. If the EEPROM (7) is selected, a CPU (4) turns on a power switch (10) to apply a high voltage to the EEPROM (7) to write the input data therein. Data stored in the RAM (6) and the EEPROM (7) are read out upon operation of a search switch and are sequentially displayed on the liquid crystal display (2). It is clearly informed whether the currently displayed data is read out from the RAM (6) or the EEPROM (7). With this operation, if data which is required to be protected against disconnection of a power supply voltage or a drop in power supply voltage is stored in the RAM (6), the data can be stored in the EEPROM (7).

Abstract: A downhole perforating tool (20) includes a perforating gun container (47) and at least one eccentrically mounted rotatable weight member (36,56). The weight members and the gun can be releasably coupled at any desired angular orientation by releasable coupling means (40,55). The tool further includes at least two spaced circumferential sleeves (30,60) to contact the borehole wall. Upon lowering the tool into a deviated well with the gun and weight member coupled at a predetermined angle, the weight member turns under the influence of gravity to adopt a lowermost position, so also rotating the perforating gun. The gun is thus positioned at the desired angle in the well borehole.

Abstract: For inspecting a transparent or translucent article especially a bottle to determine the presence or absence of a defect, particularly of a check, light is irradiated upon an inspection area of a bottle (1) being rotated or moved by drive means (5) and reflected light is photographed through an inspection table (3) by means of a two-dimensional camera (9) which includes solid-state image pickup elements. Picture element data for a first frame are fetched at a first point of time from the camera (9) and stored into a memory, and then picture element data for a second frame are fetched at a second point of time after a fixed interval of time after the first point of time. Then, differences of the picture element data for the second frame from the picture element data for the first frame from the memory are taken and binary digitized with reference to a predetermined brightness threshold level, the number of those of the differences which have one of two binary values is counted, and this number is compared with a predetermined number to accurately determine the presence or absence of a defect. 
     The apparatus includes a light projector (6), a CCD camera (9), a camera controller and processing unit (14) and electronic means (see Fig. 1) for processing the camera data so as to make the counts and comparisons.

The first electronic device also tran- simits a second authentication data, which is used for determining the legitimacy of the first electronic device, to the second electronic device. When the second electronic device is not determined to be legitimate by the first electronic device, the first electronic device does not transmit the second authentication data to the second electronic device.

Abstract: An RF antenna (201) and an associated receiver (207) are proximately located in an integrated antenna/receiver unit (200) thereby eliminating the need for baluns and inter-component cabling characteristic of prior designs. Integration of the receiver (207) with the antenna (201) provides for improved sensitivity as the need for utilizing signal dissipating and noise introducing cables and baluns to transmit the signal received by the antenna to the receiver is eliminated. Direct coupling of the antenna and receiver on a single gallium arsenide integrated circuit (243) maintains balanced impedance from the antenna to the receiver.
