Patent FI-982390-A (FI)
Inventor: RAUTAKORPI TIMO
IPC: B65H23/195
Filed: 1998-11-04
Abstract: In the method for controlling the structure of a reel, a continuous paper web (W) is reeled around a reel spool (2) to form a reel (R), and one or more variables are measured from the web (W). When a particular, predetermined change occurs in the variable, the lateral oscillation of the web is changed, by means of which the web is guided to different locations in the reel (R) in the axial direction of the reel spool (2). The change can be implemented by starting the oscillation or by changing the oscillation in progress. The change can be implemented on the basis of the changes in the transverse profile of the web (W).
Patent FI-990133-A (FI)
Inventor: KURKELA ESA
IPC: C10J3/54
Filed: 1999-01-25
Abstract: The invention relates to a process for the gasification of a carbonaceous fuel in a fluidized bed gasifier (1). In the process, a fuel (5), such as coal or peat, and a primary gasification gas (6, 7), such as air, are fed into the gasifier, and a product gas (10) is removed from the gasifier, the product gas being purified by separating fine-grained solid ingredients (16) therefrom. The solids fraction (16) which is separated from the product gas (16) and which contains unreacted carbon is fed together with a stoichiometric excess of air (27) into another fluidized bed reactor (20), which serves as an oxidizer, and the oxygen-containing gas (34) exiting from the oxidizer is directed to the fluidized bed gasifier (1) as a secondary gasification gas. By the increased oxidation, the carbon conversion in the process is increased and a residual ash with a low carbon content is produced.

Title: Improvements in pattern card saving devices for machines having rotating pattern card cylinders
IPC: D03C1/36
Filed: 1935-01-12
Abstract: 450,404. Pattern - mechanism. PERCIVAL, S., 40, Chancery Lane, London.- (Soc. A. Lehembre & Cie ; 1, Rue du Fort, Roubaix, France) Jan. 12, 1935, No. 1142. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 15, 1935.] [Class 142 (iii)] The pattern cards, which are provided with the usual perforations for controlling the bell. cranks 2 operating a loom shuttle box motion for example are also provided with other perforations. These control the rotation of notched discs 25 acting on feeler levers 14, whereby the driving pawl 16 of the cylinder carrying the pattern cards may be moved into inoperative position. Each pattern card thus controls the number of times it is repeated. The pawl 16 is carried by a lever 5, which is periodically raised by a member 27 and carries a pivot 7 and a stop 9 for levers 8 furnished with pins 19 and with pawls 21 for rotating ratchet wheels 12 attached to the discs 25. When the operative pattern card has blanks opposite to the pins 19, the levers 8 do not fall with the lever 5, and the levers 14 being engaged with notched parts of the discs 25, do not engage the pawl 16, which consequently turns the pattern cylinder. When however a hole is positioned below a pin 19, the corresponding lever 8 is allowed to fall, so that on rising its pawl turns the corresponding ratchet wheel and disc 25, which thereupon rocks the corresponding feeler lever 14 into the position shown in dotted lines. The driving pawl 16 is thereby moved into inoperative position and remains in this position until the disc has been rotated sufficiently to bring another notch into position beneath the rocked feeler lever 14. The cylinder thus remains stationary until the card has been repeated a number of times varying according to the spacing of the notches on the disc that has been operated. With three discs having notches every 2, 5 and 9 ratchet teeth respectively, the cards can be repeated 2, 5 or 9 times with one perforation situated below the pins 19, whilst with two and three perforations it can be repeated 2x5, 2x9, 5x9, or 2 x 5 x 9 = 90 times. Intermediate gearing may be arranged so that a disc rotates when the corresponding pin is opposite a solid part of the card, or plates carrying contact pieces, keys or pegs may govern the rotation of the notched discs. The Specification as open to inspection under Sect. 91 refers to an arrangement wherein the toothed wheels are controlled by gears. It also states that the contact pieces &c. act on levers. This subject-matter does not appear in the Specification as accepted.
