Inventor: VIITANEN MARKKU
IPC: D21H25/08
Filed: 1998-05-25
Abstract: The present invention relates to a method and arrangement for feeding a treating agent to an apparatus (1, 2) employed in the treating of a paper or board web for applying the treating agent to the surface of the web being treated. In the method treating agent is prepared and then supplied to the apparatus used for applying the treating agent, into the applicator chamber thereof, wherefrom the treating agent is further applied to a moving surface. The treating agent is first supplied into a feed chamber (2) communicating with said applicator chamber, and the feed chamber (2) is provided with a shunt line (10, 11) serving to remove the excess amount of the treating agent supplied to said feed chamber (2) that is not adhered to said moving surface. A pressure measurement signal at a point (22) representing the internal pressure of said feed chamber is obtained, and the feed pressure of the treating agent is adjusted to a value causing the internal pressure of the feed chamber to attain its desired set value. <IMAGE>

Title: Ultrasonic transducer for e.g. submarine projectiles - has improved electrical contact using metal film electrodes with oil filled cavities to improve sonic transmission
IPC: B06B1/06
Filed: 1964-10-29
Granted: 1979-06-29
Abstract: The ultrasonic transducer with improved mechanical resistance comprises a support which is bored out to receive a piezo-electric cylinder. The support is heated to allow the cylinder to be inverted. After cooling the cylinder is securely gripped. The temperature is maintained below the piezo-electric curie point. Before insertion of the piezo-electric cylinder the bore is coated with a thin metal layer, which forms the piezo-electric outer electrode, for example by electrolytic deposit. To ensure a perfect mechanical contact with the support the bore is evacuated and a neutral liquid such as oil forced in under atmospheric pressure to fill cavities between the cylinder and the bore wall. The liquid is retained by capillary action, with excess being drained away.
Patent GB-606258-A (GB)
Title: A process for the extraction and treatment of the blood of marine animals
IPC: A23J1/06
Filed: 1945-01-12
Abstract: The blood of marine animals, e.g. whales, is sucked out and conducted to one or more containers in a whaling vessel, while being mixed with an anti-coagulant sodium citrate, the containers then being removed to a floating factory or land station where the blood is centrifuged to separate the plasma from the red corpuscles.  Since the latter usually causes a dark colour when blood is used in sausages, meat meal, etc., the separated plasma only is used to give a lighter colour to the food product.  A whale, which has been killed, e.g. by electric harpoon, is pumped up with air and floats on its back.  A tubular spear is inserted into its aorta and the blood is sucked out into containers with baffles to minimize its swishing about. Hermetically sealed containers are preferably used and put under a vacuum so that the blood does not pass through a pump.  The containers should have water jackets or refrigerating coils to cool the blood quickly. The anti-coagulant is added either in the pipe line from the whale to the container or in the container itself.

Title: Esterification process
IPC: C07C69/76
Filed: 1961-01-10
Abstract: A benzene dicarboxylic acid, or a mixture of such acids, is esterified with an alkylene oxide containing 2-6 carbon atoms by suspending the acid in 2-6 times its weight of one or more inert organic liquid media consisting solely of one or more ketones, ethers, or alkyl benzenes, or a mixture of such compounds, these liquids being non-solvents for the acid and having boiling points not higher than 150 DEG C. and not lower than 50 DEG C., providing in the suspension 1.7-2.1 moles of alkylene oxide per mole of acid and a tertiary amine catalyst amounting to 0.5-5% by weight of the acid, this catalyst forming a salt with the dicarboxylic acid which is soluble in the organic liquid medium, and stirring the suspension at 80-145 DEG C. for 1-3 hours under inert gas pressure sufficient to maintain the medium in the liquid phase.  Pyridine, tri-n-propylamine, or N,N1-dimethyl aniline may be used as catalyst. Ethylene oxide, propylene oxide, or butylene oxide may be used for the esterification.  Examples describe the production of bis(beta-hydroxyethyl)terephthalate and the corresponding isophthalate and hydroxypropyl ester.  The esters so obtained may be subjected to polymerization to produce fibre-forming polymers.

Abstract: 682,788. Turning-gear. LAWSON, C. F. Jan. 22, 1951 [Jan. 23, 1950], No. 1701/50. Class 7 (v). In a spring-powered starter for small engines comprising an elongated tubular case 5 rotatably supporting a shaft 7 extending lengthwise of the case and project:ing at one end therefrom, a driving spring 8 in the case, the ends of which are secured to the case 5 and the shaft 7 respectively, elements, such as arms 17, on the shaft whereby the latter is brought into driving engagement with the engine by the manual application of the starter to the engine with the case 5 in line with the engine output shaft, and retaining means,'for example a unidirectional drive formed by a ring 10 and small coil spring 9, to hold the shaft during and after loading of the spring 8, such loading being performed by manipulation of the shaft end with the starter removed from the engine, there is provided means, such as a lever 14, to release the unidirectional drive so that the energy in the loaded spring rotates the engine shaft; the projecting shaft end may also embody a bell-mouthed member 18 fixed thereto, a cross-piece 15, incorporating the forwardly directed arms 17, rotable on the shaft behind the bell-mouthed member 18, a pin on the cross-piece 15 engageable with an annular-stepped cam surface in the member 18 to provide a one-way clutch connection 21 between these parts and an auxiliary spring 19 surrounding the shaft 7 to urge the cross-piece toward the bell-mouthed member 18. The metal ring 10 which is freely rotatable upon the shaft 7 has square recesses 11 into one of which normally extends a plunger 12 that is joined to a blade spring 13 on the exterior of the case 5 and lever 14. Forward of the main spring 8 on the shaft 7 is the coil spring 9 one end of which is fixed to the ring 10 so forming the unidirectional drive, the spring being wound in such a direction as to permit rotation of the shaft 7 in the direction which tensions the driving spring 8 and prevents the shaft from rotating in the opposite direction until the lever 14 is actuated. The arms 17 of the cross-piece are rubber covered and engage an aircraft propeller whilst the member 18 fits over the "spinner" so that the propeller may be rotated by expansion of the spring 8 upon actuation of the lever 14. The spring 8 is tensioned by rotating the cross-piece by hand or otherwise in a direction opposite to that in which the engine is turned for starting. In a modification, the metal ring is fixed to the shaft and the recesses therein are of ratchet form; the plunger is similarly shaped so that the small coil spring may be dispensed with since the unidirectional drive is effected by the ratchet action of the ring and plunger. The starter may be also used to start model motor car engines.

Three bars 87 are at the same time actuated to form inwardly-projecting spurs. 4 on the tube. The movements are then reversed and the carriage withdrawn, the tube being replaced automatically by an untreated tube, the cycle of operations then being repeated.
