Patent NO-158593-C (NO)
Inventor: BRODEN GERT
IPC: F23D14/42
Filed: 1986-02-13
Abstract: A device in a cutting torch which comprises a torch body with a valve housing and a nozzle and with a cutting oxygen duct, a heating oxygen duct and a combustion gas duct disposed in the torch, there being disposed in the torch a connection line which contains a throttling member between the heating oxygen duct and the cutting oxygen duct and wherein disposed in the cutting oxygen duct before the connection line is a valve member which permits a flow of heating oxygen to pass through the cutting oxygen duct only in the direction towards the orifice of the nozzle.The connection line between the heating oxygen duct and the cutting oxygen duct comprises at least one cooling oxygen duct (7) disposed in the nozzle which is elaborated with three sealing surfaces towards the torch body. The cooling oxygen duct (7) has a diameter which is so adapted in relation to the orifice diameter in the cutting oxygen duct of the nozzle and to the size of the heating flame that during heating of the workpiece a cooling oxygen pressure is rapidly built up in the cooling oxygen duct which prevents hot combustion gases from penetrating into the cutting oxygen ducts and that in the case of short nozzle distances to the workpiece the flow of cooling oxygen is prevented from becoming so great that the surface of the workpiece which is situated below the orifice of the cutting oxygen duct is cooled so rapidly that hole-piercing is rendered more difficult.

Filed: 1990-09-20
Abstract: A method and an apparatus for plant flaming, while using liquefied petroleum gas as fuel, the liquefied petroleum gas (1.4) being evaporated in an evaporator (1.5) intended therefor, the evaporator (1.5) being a plate heat exchanger (2), and heating of (supply of energy to) the evaporator (1.5) being effected in that the cooling water via couplings (1.7, 1.8) from a vehicle (1.1) is connectible to the flaming apparatus (1.2) and conducted past the heat exchanger (2) and back to the vehicle. For reasons of security, the evaporator (1.5) is provided with thermostats (3.5, 3.10) which via valves (3.6, 3.9) ensure that excess temperatures or insufficient temperatures do not arise in the operating evaporator. This prevents the liquid from emerging and the containers from exploding.

Granted: 1994-09-13
Abstract: A digital binarization circuit for image data includes a background level detecting circuit which uses a video signal as a reference input for determining the background level of an image represented by the video signal, and outputs the background level as a first address signal.  A character level detecting circuit compares the video signal with a character level in a load decision comparator and loads the video signal as a character level when the signal is less than the reference level, and outputs the character level as a second address signal.  A memory circuit outputs a threshold value stored at an address designated by the first and second address signals to a comparator.  The optimum threshold value is outputted among prescribed threshold values stored in the memory circuit.  The comparator compares the digitized video signal with the optimum threshold value and outputs a binary signal corresponding to the comparison result.  Even for original documents with a dark background, noise is not liable to occur in the transmitted video signal, and a light character can appear clearly on the transmitted video signal.

Title: Spring loaded locking system for box spring assemblies
Inventor: DABNEY UPTON R
IPC: A47C27/07
Filed: 1991-05-07
Granted: 1995-03-21
Abstract: A spring loaded locking system for a box  spring assembly having a generally rectangular frame, a plurality of spring modules and a grid type wire support deck disposed a predetermined distance above the frame.  The locking system provides an interference fit which secures the spring modules to the support deck.  Each spring has a pair of outwardly open V-shaped sections integrally formed with the upper portion of the spring.   The vertices of the V-shaped sections commonly contact one wire of the support deck.  A pair of legs extends from each vertex and straddle the common wire and either cross one of a pair of parallel brace wires of the support deck.          The V-shaped sections are biased apart from each other by the shape of the upper portion of the spring module itself.  The interaction between the vertices and the common wire, between the legs and the brace wires,  and the outward bias of the upper portion of the spring module provides an interference lock fit which secures the support deck to the spring module.

Title: Anti-oxidation agent for continuous annealing of stainless steel strip and anti-oxidation method using the same
Inventor: SATO KUNIAKI
IPC: C21D1/70
Filed: 1991-07-09
Granted: 1999-04-06
Abstract: An anti-oxidation agent for preventing oxidation of a stainless steel strip during continuous annealing comprising a colloidal inorganic substance which can be crystallized at a temperature not higher than 1300°C at least one compound having a melting point not higher than 1300°C, selected from the group consisting of silicates, borates and phosphates, a dispersion agent, and the balance substantially water.  The anti-oxidation agent is applied to the surface of the stainless steel strip.  During the annealing, the anti-oxidation agent enhances the heat absorption so that the stainless steel strip temperature is elevated to the annealing temperature in a short time.  The anti-oxidation agent on the strip surface forms a film of a fine structure which keeps the strip surface away from oxidizing components of the annealing atmosphere so as to suppress generation of oxide scale.  The film is easily separated due to thermal contraction in the course of the cooling after the annealing.
