Patent MX-9804088-A (MX)
Title: Spray nozzle.
Inventor: TSCHUMI OTTO
IPC: E04F21/08
Filed: 1998-05-22
Abstract: A spray nozzle of the type adapted to feed a liquid to a material being sprayed therefrom comprises a tubular spray conduit around which is arranged an annular feed port, this feed port being closed in a liquid-tight manner by resilient material openable by liquid pressure and whose degree of opening, and therefore the quantity of liquid fed to the material, rises linearly with increasing liquid pressure. Preferably, the resilient material is provided by a membrane ring (7) which is a flat ring with inwardly-tapering radial ridges (8b) raised thereon, the gaps between the ridges being filled with an elastomeric material, such that a series of resilient segments (9) is created. Under liquid pressure, the segments are compressed equally, giving a nearly completely annular flow of liquid into the material. The nozzle is particularly useful for the spraying of concrete, especially by the dry method.

Title: A physical layer authentication method for edge device Combining threshold and machine learning
Inventor: HONG WEN
IPC: H04L29/06
Filed: 2020-05-22
Abstract: The invention discloses a physical layer authentication method based on edge devices, which takes the advantages of the threshold and the machine learning. Firstly, the maximum repetitive authentication number and the authentication threshold of physical layer information packet are set. Then several terminals perform authentication shaking hands with the edge device. After the identity of terminals is confirmed, they access the edge computing system. Every terminal continuously sends packets to the edge device. When the edge device receives the packet sent by the jth terminal at the ith time slot, it extracts the current channel information matrix as the basis of packet authentication. The edge device adopts the threshold method to perform the physical layer information package authentication, while it carries out the machine learning of the physical layer information package authentication at the same time. After the machine learning authentication method is completed, this machine learning method is used for authentication by the edge device. The novel method improves the authentication rate of physical layer information package and avoids long-term training.

Patent NL-7217341-A (NL)
IPC: C10G69/06
Filed: 1972-12-20
Abstract: 1419260 Hydrocarbons; hydrocracking PIERREFITTE-AUBY 19 Dec 1972 [21 Dec 1971 24 Oct 1972] 58514/72 Heading C5E A hydrocarbon feed is cracked to olefines in the presence of hydrogen and in the absence of bromine at a pressure between 10 and 70 bars, a molar concentration of hydrogen not less than 20%, a reactor outlet temperature between 625‹ and 1000‹ C., and a residence time between 0À01 and 0À5 second. The feed may be a C 3  fraction, a C 4  fraction or a steam-cracked gasoline but is preferably low in aromatics. The hydrogen need not be pure, so long as the contaminants are inert or do not cause undesirable reactions. Steam may also be present as diluent. As shown, the feed is compressed at 1, mixed at 11 with hydrogen and cracked at 2. The products are separated at 3 into gas 4 and liquid 5, which are fractionated separately at 6 and 7. Methane, ethane, ethylene, propane and propylene are recovered as products from 6, or the ethane and propane fractions may go to an additional steam-cracker 8, the products from which are returned to the fractionator 6. Hydrogen from fractionator 6 is recycled. Heavy fractions from 6 are transferred to fractionator 7, whereas light fractions of the liquid 5 are transferred in the opposite direction. Fractions from the fractionator 7 may be taken off as products, e.g. for gasoline, used as quench at 15, recycled by line 13 or recracked at 14. Small proportions of sulphur in the feed as organic compounds or as H 2 S reduce coke formation. A build-up of aromatics should be avoided by taking off a suitable fraction, similar to coke-oven benzol at 7.

Title: Membrane filtration unit - with rigid membrane supporting tubes between end plates, flexible cylindrical seal between tube and end plate with rigid retaining sleeve
IPC: B01D63/06
Filed: 1977-10-27
Abstract: A membrane filtration unit consists of an outer cylindrical shell with end plates and dished end covers. The membranes are cylindrical and supported by rigid tubes which are perforated to permit the passage of liq. The membranes and tube assemblies fit between the end plates, holes in the plates providing communication between the end chambers and the inside of each tube. Fluid feed and discharges are in the dished ends of the unit whilst the permeate discharge is in the shell. An elastic sleeve (esp. of PVC) inside the tube ends effects a seal between tube and end plate and a rigid tube with an outer dia. pref. slightly greater than the inside dia. of the sleeve is pushed into the tube ends to retain the seal. Lips punched out of the wall of each retaining sleeve prevent it from moving. This form of construction is simple and economic using readily obtainable components for the sleeve assembly.

A recess is formed in the housing at the height of the axis of rotation, and a bearing supporting the roller is inserted between housing and flanges. This is enclosed between one end of the ridge and a stop fixed to the bearing block.
Patent NL-8103919-A (NL)
Title: Steel converter tilted via gears by motors with brakes - has resilient couplings between gear pinions and brakes to prevent tooth fracture
IPC: C21C5/50
Filed: 1981-08-24
Abstract: The drive system is intended for tilting a vessel such as a steel converter and comprises at least one (usually one either side) gear wheel on a stub shaft on the vessel meshing with a number of (e.g. four) drive pinions. Each pinion is driven by a motor whose shaft carries a brake drum. A resilient coupling is arranged between each pinion and the respective brake, e.g. between a rearward extension of the motor shaft and the brake drum. The arrangement gradually takes up the tooth play at successive pinions in the event that the tilted vessel is caused to tilt further through external circumstances so that the force resulting from this tilting moment acts on teeth of all rather than one pinion. The arrangement prevents tooth fracture of drive gearing if the vessel is caused to tip beyond its tilted position, e.g. because a scrap loader is placed roughly on the rim of the converter.

Title: Geophone with stationary coil and moving permanent magnet - mounted on spring bushes and polarisable according to direction of vibrations expected
IPC: G01H11/02
Filed: 1983-10-24
Abstract: Conventional geophones, i.e. seismometers for geophysical research, have a fixed permanent magnet inside a pick-up coil which is vibrated by the seismic shock. The movable coil can produce harmonic distortion and its connections can be damaged by excessive vibrations. The present geophone has a movable, hollow, cylindrical, permanent magnet (116), mounted on spring bushes to the outer housing (114) of the geophone. The pick-up coil (110) passes through the hollow body of the magnet in a cylindrical housing (112). The magnetic body (116) may be radially or axially polarised, dependent on the direction of the vibrations it is required to detect. The present geophone is more robust than conventional geophones and less likely to produce harmonic distortion.

Title: Machine determining oxygenation factor in living tissue - measures extraction ratio between oxygen in blood and oxygen use
IPC: G01N33/84
Filed: 1990-04-09
Abstract: The system determines the level of tissue oxygenation by calculating the balance, or 'extraction ratio' - ER- between available oxygen or 'oxygen flux' and the oxygen use by the tissues - VO2. The techniques involves the measurement of the strong binding between haemoglobin and oxygen. The oxygen flux is calculated by multiplying the heart output rate, or 'heart minute volume' by the proportion - CACO2- of oxygen in arterial blood. The extraction ratio, ER is then calculated by dividing the oxygen use figure - VO2 by the oxygen flux. The application contains no technical details of the construction or operation of the machine.
