Patent DE-4304758-A1 (DE)
Title: Double layer fourdrinier for paper-making machine - has structured weave to give equal warp use in both layers for supply from a common beam
Inventor: JAALA ERKKI
IPC: D03D11/00
Filed: 1993-02-17
Abstract: The fourdrinier for a papermaking machine, of two woven layers, uses equal warp wires throughout with a flat cross section. The cross section surface and shape of the weft wires for the lower layer are structured so that the warp wires have an equal length deployment, per length unit of the fourdrinier, in the upper and the lower layers. The warp wires pref. have an oval or elliptical cross section. The weft wires for the lower layer are in the same location between the warp wires as the weft wires in the upper layer, for the warps to be moved to bond both layers together. The weft wires for the lower layer, during weaving, remain between all warps of the lower layer and warps of the upper layer, to form a weave without holding the upper layer. The upper layer is of a single layer of weft wires woven with warp wires, and the bonding is through warps from the lower layer passing through the gap between two warps in the upper layer, or between the warps and wefts of the upper layer. The lower layer has only one layer of weft wires. USE/ADVANTAGE - The fourdrinier, for the drying section of a papermaking machine, is in two woven layers bonded together. The structure gives no visible irregularities in the surface and, as the warp consumption is taken from the same length, a common warping beam can supply the warp wires for both layers.

Title: Breast pad that can be boiled and tumble-dried
Inventor: SPORMANN ANNA
IPC: A61F13/14
Filed: 1993-03-23
Abstract: The invention describes a breast pad for the brassiere of nursing mothers, which differs from conventional breast pads in that it can be boiled and dried in a tumble-drier. When washed in this way with the baby's laundry without any additional effort the breast pad can be hygienically reused and is comparatively inexpensive. The need to keep a stock of disposable breast pads is dispensed with and refuse is reduced. The breast pad is made of at least two mutually connected layers one of which has a high liquid-absorbing capacity and the other is skin-compatible and lint-free.

Title: Method for the production of flat polarising interference-layer components, and components produced in this way
Inventor: BIEDERMANN ANDREAS
IPC: G02B5/30
Filed: 1993-05-18
Abstract: The invention teaches a method for the production of flat polarising interference-layer components and specifies flat components produced in this way. By folding coated planar substrates and by the simultaneous formation of edges, production according to the invention avoids the necessity of coating complicated formed bodies (mouldings). At the same time, components having very good optical properties are produced, in particular when transmission-impeding (transmission-restraining) arrangements are used at the edges.

Patent DE-4341160-A1 (DE)
Inventor: HUMS ERICH DIPL CHEM DR
IPC: B01D53/56
Filed: 1993-12-02
Abstract: In the production of a catalyst containing a catalytically active Mo-V-O phase, the problem exists of keeping the Mo-V-O phase and/or an Mo-V-Ti-O phase substantially free of other catalytically active impurities in order not to catalyze competing reactions at the same time. For this purpose, the invention provides that vanadium oxide and molybdenum oxide are mixed in a ratio of 0.7 to 1% by weight based on V2O5 and MoO3, the mixture is heated to a temperature above 500 DEG  C., the Mo-V-O phase is cooled, ground and then subjected to a reducing treatment, and dispersed on a heated oxidic support, the dispersed material is then ground, and then applied to a suitable macroscopic support, optionally with further additives, and calcined. Alternatively, the material dispersed on the oxidic support can be kneaded with additives to form an extrudable compound, and the compound can be extruded and then calcined so that the honeycomb bodies produced from the compound have crosspiece widths in a range of from 0.1 to 0.6 mm and cell densities of 50 to 1200 cells per square inch.

Abstract: Apparatus for detecting carrier signal cycle slip errors occurring at a receiver (200) in a satellite-based navigation system, such as NAVSTAR GPS, includes means for computing a first velocity of the receiver (200) along a vector between the receiver (200) and a satellite (102), based on the received carrier wave, inertial means (318) for measuring a second velocity of the receiver (200), comparison means (324) for comparing the first velocity with a component of the second velocity along the vector, and flag means (324) for generating a cycle slip error flag when a difference between the first velocity and the component of the second velocity along the vector exceeds a predetermined value. The cycles of the carrier wave of the navigation signal from satellite (102) are counted over a time  DELTA t, to give the first velocity. If a cycle slip is detected a Kalman filter can be "opened up" to reduce the "inertia" of the system. <IMAGE>

Title: Quick process for repairing leaking socket connections in pipelines upon which it is possible to drive
Inventor: GRIESER ALOIS
IPC: F16L21/02
Filed: 1994-10-12
Abstract: The pipe-joint seals, used for prestressed-concrete pipes, in the spigot and socket connections with a roll-on joint have not satisfied the stringent operational requirements everywhere and began to leak. The supply and disposal lines in question can often only be taken out of operation for a short period of time for the necessary repair work. In comparison with the known repair methods for leaking socket connections by means of pipe sleeves which involve a high degree of outlay and narrow the line cross-section, the novel process ensures the following advantage: the repair work takes place exclusively in the socket gap with a relatively low degree of outlay in terms of time and material and an accompanying, extremely short period of time during which the line is out of operation. In order to repair the leaking socket connection (1) from the inside, a rubber hose (2) is inserted into the socket gap between the bell and the spigot end of the pipe projecting into the socket, and is injected (grouted) under pressure with a two-component material (3). This quick process is particularly suitable for repairing leaking socket-pipe connections in pressure pipelines. This seal permits movements in the longitudinal direction and in the transverse direction and is equally suitable at subatmospheric pressure in pipelines. <IMAGE>
