  • Patent number: 5138823
    Abstract: An insertion device is used to introduce foil-like material, in particular paper or synthetic segments, between the slices cut by a cutting machine. Such slices are produced in particular in the food industry in the form of sausage, cheese or other food slices with cutting machines. In the insertion device a paper path is unwound from a paper roller and is carried into the cutting range of the circular knife of the cutting machine through an intermittently driven feed device. The insertion device of the cutting machine is arraged on the machine frame so that it can be moved and secured in order to be able to readily clean the insertion device and also to make the corresponding intake area of the cutting machine readily accessible.

  • Patent number: 5139904
    Abstract: A method of producing high-resolution and reproducible patterns, typically polysilicon ultra-fine lines. According to a preferred embodiment of the method, a layer of a standard radiation-sensitive resist is applied over a polysilicon layer formed on a substrate. The photoresist is delineated as is standard in conventional UV lithography equipment to produce a first resist pattern. The structure is then placed in reactive ion etching (RIE) equipment and the resist pattern is isotropically eroded to reduce overall dimensions. The etched thickness (dTH) is accurately measured by interferometric techniques, so that the corresponding lateral dimension reduction (dW) is continuously monitored. The etching is terminated when the appropriate lateral dimension reduction has been obtained to produce a second resist pattern of the desired final width (LWf). The second resist pattern (17a') is then anisotropically transferred to the underlying polysilicon layer by reactive ion etching.

  • Patent number: 5138642
    Abstract: A detector arrangement is disclosed for an industrial CT x-ray system which uses a three dimensional cone beam to irradiate the specimen and a large two dimensional scintillation screen to develop a light image corresponding to the energy of the attenuated radiation beams. The light image is focused by a special lens arrangement with zoom capability onto the photocathode of an intensifier. The intensified light image developed is transmitted by fiberoptics to a plurality of CCD chips, each chip developing electrical signals corresponding to a segment of the image developed in the intensifier. The chips are clocked in a predetermined manner based on a prior information developed in an initial scan to produce a high resolution image of large industrial objects in a short time.

  • Patent number: 5134877
    Abstract: A portable counterflow helium leak detector has only one pump. The pump is a secondary vacuum pump including an inlet and an outlet. A gas analyzer is connected to the inlet of the pump. The outlet is connected via an inlet valve to a correction orifice for connection to an installation to be tested, the installation being evacuated or being capable of being connected to a primary pump. The detector further includes electronic power supply and control circuit, a power supply, and a display. The detector further includes a first pressure gauge situated between the inlet valve and the connection orifice and an ON/OFF control switch for controlling detector operation. The electronic control circuits cause the inlet valve to open and the secondary vacuum pump to start whenever the detector is powered. The control switch is in the ON position and the pressure measured by the first gauge is below a determined value.

  • Patent number: 5136235
    Abstract: A fiber-optical current transformer including a sensor coil, operated in reflection mode, with a sensor fiber (5) for detecting a current utilizing of the Faraday effect. A light source (1) couples light into an incoming first HB fiber (2a). At the end of the first HB fiber (2a), a fiber-optical polarizer (4) is preferably located which ensures a direction of polarization in parallel with a given birefringence axis of the first HB fiber (2a). A Y splitter (3) couples, on the one hand, the supplied light of the first HB fiber (2a) into the sensor fiber (5) and, on the other hand, the light coming from the sensor fiber (5) into an outgoing second HB fiber (2b). The second HB fiber (2b) is rotated with its birefringence axes by 45.degree. with respect to the birefringence axes of the first HB fiber (2a).

  • Patent number: 5135859
    Abstract: This invention relates to a process for producing polyester biopolymers by culturing Pseudomonas oleovorans bacteria on substrates comprising certain nutrients. The nature of the polyesters can be varied by varying the nature of the carbon source used. In this way polyesters with unsaturated double bonds can be produced, too. From the polyesters, optically active carboxylic acids or esters are produced. The polymers can be used for making articles of manufacture, such as sutures, films, skin and bone grafts.

  • Patent number: 5136535
    Abstract: A hybrid CMOS-bipolar memory cell for a high speed memory includes a CMOS latch which has two storage nodes (104) and (106) for storing two logic states. The CMOS latch is disposed between a high voltage node (110) and a low voltage node (114). The two nodes are maintained at a predetermined voltage to maintain a static state. A bipolar current drive transistor (120) is provided which is connected to one of the storage nodes (106) to provide a low source impedance for output from the memory cell. A work line (44) is connected to the high voltage node (110) for selection thereof by varying between two predetermined voltages. The cell is written to be selectively discharging either node (104) or (106) to a low voltage node (114) through bipolar transistors (122) and (124). The bipolar transistor (122) and (124) provide high transconductance switches for selectively discharging the storage nodes (104) and (106).

  • Patent number: 5134340
    Abstract: A printhead for a light emitting diode printer has a transparent substrate with a row of LED dice mounted on the substrate with their light emitting junctions adjacent to the substrate so as to emit light through the substrate. Each die has a row of LEDs along its length and a row of connection pads at known locations for making electrical connection to the LED anodes. Metal lines are deposited on the transparent substrate at known locations. Solder bumps between the connection pads and metal lines precisely position the dice by reason of surface tension. The dice are positioned in parallel rows with alternate dice staggered from each other for electrical isolation and to avoid mechanical interference at the ends of adjacent dice. In the event placement by way of the solder bumps is insufficiently precise, an opaque layer may be deposited on the substrate with a row of windows adjacent a row of LEDs. The windows are smaller than the LEDs so as to mask edge portions and alleviate alignment requirements.
