Patent GB-223927-A (GB)
Abstract: 223,927. Grewin, F. Oct. 24, 1924. Drying.-To facilitate drying in paper, cardboard, pulp, and like machines, currents of air, which may be heated, are blown with great velocity through the confined spaces formed by the different parts of the machine together with the paper web or the like and the drier felts, the pressure, velocity, and direction of the jets being such that the air currents do not come in contact' with the material being treated. The moisture is thus abstracted by suction effect and carried off. Compressed-air piping 1 is laid along both sides of the machine, and successive nozzles 3 are alternated on both sides of the machine, thus setting up the currents in opposite directions.

Title: Method of and apparatus for treating fur or felt hat bats
IPC: D04H17/12
Filed: 1924-06-02
Abstract: 240,779. Marks, E. C. R., (United States Hat Machinery Corporation). June 2, 1924. Bodies, felting.-Hat bats are " crozed " by progressively shifting one ply of the substantially flat or unrolled bat relatively to the other ply during the shrinking and felting operation. The bats B are placed on an endless belt 10 the outer surface of which consists of a multiplicity of rubber pyramids forming elastic kneading projections. The belt passes around end rollers and over supporting rollers 13. Deflecting rollers 14 force the belt into a sinuous or wavy form. All these rollers are driven by gearing at the same peripheral speed. Pressure rollers 15 are provided between the deflecting rollers and are driven either frictionally by contact with the belt or bat, or by gearing at a less peripheral speed than the other rollers. The effect of the lag of the pressure rollers and the bending of the belt is to cause waves to be formed in the upper ply of the bat behind the upper rollers as the bat is passed through the apparatus, thus relatively shifting the two plies, or " crozing " the bat. Each bat is passed through the machine a number of times with different parts of its periphery foremost, at the discretion of the operator, while hot water is showered on the work.

Title: A method for recovering oil and meatmeal from whale meat
IPC: A23K1/10
Filed: 1939-08-09
Abstract: 533,300. Treatment of whale meat. AKTIEBOLAGET SEPARATOR, LEVER BROS. & UNILEVER, Ltd., and BOSTOCK, B. R. Aug. 9, 1939, No. 22973. Convention date, May 20. [Class 91] Oil and meatmeal are recovered from whale meat by boiling or digestion in a rotary digester, subjecting the product to a purification in a centrifuge with an imperforate drum wall, and centrifuging the remaining liquid for recovery of the oil. It is preferred that after the digestion the majority of the oil should be separated in a gravity separation tank and the residue should be separated from the bulk of solid matters by straining, advantageously in a revolving or vibrating strainer or both, before submitting to the first centrifuging operation. The frequent stoppage of the centrifuge to remove solid matters is thus avoided. The second centrifugal treatment of the materials from the digestion is largely a treatment of a mixture of oil and glue water. There is, however, some solid matter present and for this reason the second centrifuge is preferably provided with a device for intermittent discharge of the separated solid matters. The Specification as open to inspection under Sect. 91 includes the treatment of any animal material to separate the oil and meatmeal. The use of a particular type of centrifugal apparatus is not essential, but after the boiling operation the products are subjected to a repeated purifying for removing and recovering solid matters. This subject-matter does not appear in the Specification as accepted.

Abstract: 989,059. Rolling. UNITED ENGINEERING & FOUNDRY CO. June 26, 1961 [July 6, 1960], No. 23006/61. Heading B3M. ]Also in Division G3] In an arrangement in which a roller, carried by an arm angularly displaceable, by a link of fixed length, about a first pivot deflects strip material passing between successive units, an extensible strut is connected at one end to the link of fixed length and pivoted at its other end about a second pivot, the triangles formed by the strut and link and by the deflected strip and its pass line being dissimilar but so dimensioned that the strip tension bears a substantially constant relationship to the force within the strut. In Fig. 3, strip material S passing from a rolling mill 12 to a rolling mill 13 is deflected upwards by an idle roller 14 supported by an apron 15 which is adjustable about a pivot 16 by a strut 21 pivoted at 22 to a jack 23. The other end of jack 23 is pivoted about a point which may be fixed as shown or on a bell-crank lever for vertical adjustment by operation of a hand wheel controlling a worm drive. Formulas are given to facilitate the dimensioning above referred to and, as a result, roller 14 exerts a constant pressure on the strip S if a constant hydraulic pressure is applied to jack 23. A further jack 41 which serves to balance out the weight of apron 15, roller 14, and the strip, may also serve as a stop to determine the lowest position of roller 14. An electrical signal representative of strip thickness, produced by an X-ray gauge 45 is compared with a signal from a potentiometer 47 representative of desired thickness and any error is effective to control jack 23 through an electro-hydraulic system so that strip tension is varied to restore strip thickness to the desired value. A transducer 92 associated with jack 23 supplies a voltmeter 91 which, like setting voltmeter 50, is calibrated to read strip tension. Use of the system to maintain a strip tension corresponding to the setting of potentiometer 47 without employing gauge 45 is referred to. If desired, the system may be operated so that voltmeter 91 indicates variations in tension of the strip as it passes through the mill. Under these conditions reduction of hydraulic pressure due to excessive slackness of the strip operates a switch 66b to raise roller 14 into contact with the strip. Operation of a limit switch 98 effects restoration of the system to indicate tension again. The output of transducer 92 may also control the speed of the electric drive of mill 13 to assist in maintaining constant tension. The speed of this mill may alternatively be controlled as shown by a potentiometer 97 adjusted by movements of roller 14 to maintain a substantially constant size of loop. Application to a multi-stand mill involving a plurality of the above control systems for controlling tension, thickness and/or indicating variations in tension is described.
