Abstract: A reinforcing web has two elongated reinforcing layers. Each reinforcing layer consists of parallel fiber segments which are inclined to the longitudinal axis of the respective layer at an angle of 30 to 85 degrees. To make the web, adhesive with a protective covering is applied to one surface of an elongated band. The band consists of fibers which run parallel to the longitudinal axis of the band. The coated band is wound onto a take-off reel which travels along an endless track. The track is located next to a pair of supports and can rotate 90 degrees to either side of a middle position in which the track is parallel to the supports. The track is swivelled from the middle position through an angle which is a function of the desired orientations of the fiber segments. The take-off reel then begins to move along the track, and the band is deposited on the supports as the reel moves. A take-up reel which travels with the take-off reel winds up the protective covering of the adhesive.

Abstract: A lamp processing machine for separating glass, powder and metal lamp components placed within the machine. The machine may include two generally cylindrical, concentrically mounted screens and a tube concentrically mounted between the screens. The screens may be mounted within an enclosure having separate outlets for the powder, glass and metal.

Abstract: A protective sheath for a pulse oximetry sensor. The sheath covers the sensor and inhibits contamination thereof during use. The sheath obviates the need to clean the pulse oximetry sensor after each use while reducing the likelihood of cross-patient contamination. The sheath allows the use of reusable pulse oximetry sensors and thus significantly reduces the overall costs of such sensors per use.

Abstract: An apparatus for vertically aligning a given point on a pressure transducer unit with a desired point an a patient, the apparatus comprising: (a) a light source; (b) a housing adapted to contain the light source; (c) at least one leveling tube having a leveling axis that is substantially parallel to the light beam, the leveling tube comprising (i) a closed transparent envelope containing a liquid and a bubble of gas, and (ii) lines formed on the envelope, where the leveling axis is substantially horizontally aligned when the bubble of gas is located between the two lines; (d) an indicating mark formed on the housing means, where the beam of light is vertically aligned with the given point on the transducer unit when the indicating means is vertically aligned with the given point on the transducer unit; and (e) a locking system for selectively locking the housing means to prevent movement thereof relative to the transducer unit when the beam of light is both horizontally aligned and vertically aligned with the

Abstract: A volatile semiconductor memory module (RAM) is combined with a permanent memory based on an electrically polarizable, preferably ferroelectric, layer within an integrated monolithic module in such a manner that, as a result of a STORE command, the information present in the semiconductor memory is permanently stored by polarization of selected regions of the electrically polarizable layer. In the same way the permanently stored information can be read out again as a result of a RECALL command and returned to the semiconductor memory. Preferably, a ferroelectrically polarizable layer 11 is applied to the semiconductor memory, which layer, in the same way as the semiconductor memory, is provided on its upper side and underside with word and bit lines in the form of strip electrodes, 9,12. The strip electrode system 9 on the underside of the ferroelectric layer 11 simultaneously forms the word or bit line system of the semiconductor memory facing the surface.

Abstract: A method of manufacturing a shape from a composite material by applying laminations impregnated with plastic resin to a positive mold. At least one cellular, cellular-core layer is applied into the neutral zone of the laminations and embedded into them while the laminations are being built up. The cellular layer is a rigid foam. The cellular-core or honeycomb layer has the axis of each cell radial to that of the shape and can be single, double, or multiple. If double or multiple it may have an interior connective layer consisting of plastic, foil, glass cloth, non-woven carbon-fiber fabric, polyimide, or woven or non-woven fabric impregnated with plastic resin. The cellular-core or honeycomb layer is intended to make the shape more stable and flexurally strong.

Abstract: A method and an apparatus are described for making a filamentary web. One or more strands of roving, each composed of multiple filaments, are spread out to increasing extents until the filaments form a band in which they extend unidirectionally and generally parallel to each other, but are not connected with one another. Adhesive strips, threads or other connecting elements are then transported on a carrier into a working station so as to be positioned transverse to the elongation of the band. In the working station, they are transferred to the band and joined to the filaments under application of contact pressure in the nip between cooperating nip rollers. This converts the band into a unitary filamentary web structure in which the filaments are all unidirectionally oriented.

Abstract: The invention relates to a laminate reinforcement for fibre-reinforced sunthetic resins and has for its object to provide a laminate reinforcement of highly resistant and high elasticity modulus fibres for extremely heavy-duty, yet light-weight and indent-resistent floating bodies and provides to that purpose such a reinforcement in which the laminate reinforcement is obtained by means of at least two parallel tissue tapes forming by their tissue seams a paunch gap, which is covered with a similar, but narrower covering tape, doubling of the reinforcing fibres in the area of the paunch gap in parallel relationship producing a Stringer effect, in which the warp and weft yarns of the tissue tape are made from reinforcing fibres having a higher elasticity modulus and a higher specific tensile strength than glass fibres, said fibres consisting of carbon, aramid, boron fibres or the like, the warp yarns of carbon and aramid being in intimate contact with one another and the weft yarns of aramid or carbon being spa

Abstract: A rubber scraper is slidably received in a guide frame. A horizontal cross member supports the bottom edge of the scraper. Counterweight assemblies are attached to the ends of the cross member and function to raise the scraper through the frame toward the underside of the conveyor belt to be scraped. The counterweight assemblies each include a counterweight running in a downwardly curved guide so that, as the weight of the scraper diminishes due to wear, friction and the support of the curved guide acting on the weight gradually decreases the force with which the counterweight pulls on the cross member, thereby ensuring that the scraper applies a generally constant pressure against the belt.
