Patent SE-7910025-L (SE)
Inventor: WALKER P J
IPC: D21F7/00
Filed: 1979-12-05
Abstract: In a method and apparatus for the uniform drying of a continuous web, such as a sheet of paper or paperboard, a newly formed web of paper of wet cellulosic fibers and the necessary additives is initially directed through a press section where excessive water is squeezed from the web to reduce its moisture content to about 50-80 percent, by weight, for subsequent passage through a dryer section wherein the moisture content is further reduced to between 3 and 15 percent, depending on the quality of the paper being processed. The moisture content profile of the nearly dry web of paper is constantly monitored adjacent the discharge end of the dryer section for dry streaks which occasionally occur in the web. Moisture is added to the web upstream from and longitudinally aligned with the dry streaks when the web is relatively wet and has a moisture content of at least 25 percent to eliminate further dry streaks.

Abstract: A triangle waveform having substantially linearly sloped, gradually increasing and decreasing edges and having a frequency nf is generated from an n-phase sine wave signal, each phase having a fundamental frequency f. A segment of any of the n-phases of the sine wave is detected when that segment is within a predetermined angular amount from a reference crossing level, such as the zero crossing of the sine wave signal. Successive ones of the detected segments are selected to synthesize the triangle waveform. In the preferred use of this invention, the triangle waveform is compared to a reference signal, such as the sine wave signal from which the triangle waveform is generated, this reference signal having a controllable frequency and amplitude. Pulse transitions are generated at the intersection of the triangle waveform and each of the respective phases of the reference signal. In one embodiment of this invention, the frequency of the triangle waveform is increased by an amplitude- folding technique wherein the triangle waveform (of frequency nf) is folded about a pair of equal but opposite folding levels whenever the triangle waveform reaches either of these levels, so as to produce an amplitude-folded triangle waveform of frequency mf and of peak levels determined by the folding levels.

Abstract: An adsorbent, characterized by a carrier with covalently bound ligands consisting of a solid phase which is completely or partially penetrated by or surface coated with a hydrophilic, molecular, polymeric netting. The bound ligands consist of atom or atomic group Y and a group X located terminally from Y in the ligand, wherein Y and X are separated from each other by two consecutively bonded carbon atoms and wherein X is SO2, SO, S or Se, and wherein Y is S, N, NR or NR2, where R is hydrogen or alkyl. The solid phase is formed of particles preferably of smaller diameter than 1 mm, and the polymeric lattice is formed of a polyhydroxy polymer such as a polygalactane, e.g. agar or agarose, or a polyamide such as a cross-linked polyacryl amide or a derivative thereof. The ligand has the structure R1-X-CH2-CH2-S- where R1 is an arbitrary aliphatic, aromatic or heterocyclic group having for example the structure -(CH2)m-(CHQ)n-H wherein Q is H, OH or SH and wherein n = 1, 2 or a higher number and m = 0, 1 or a higher number. The adsorbent is prepared by first introducing thiol groups into the polymeric netting for subsequent alkylization with vinyl- beta -haloethyl sulfone, -sulfoxide or sulfide. The adsorbent can be used, with an excellent result, for the fractionation of biopolymers such as proteins, for example.

Abstract: A fluid pressure sensitive releasing device comprising a body (20) of a material which has a certain strength in a condition in which it is affected by fluid and which strength is considerably reduced with exposure of the material to fluid. The body is used in its non-influenced condition to maintain a release member (21) in a secure position whilst the member is arranged to be displaced to a released position, preferably by the action of a spring (28), when the material of the body reduces its strength due to the influence of fluid. According to the invention the body is kept separated from the surrounding atmosphere, whose possible humidity could influence the body to reduce its strength, by means of a valve arrangement (5, 32). This is arranged to separate the body from the surroundings by means of a sleeve (32) of sealing material which is arranged to be penetrated by parts (34) which are arranged to be displaced when the device is subjected to a certain pressure. Once penetrated, the body is exposed to the surroundings. When the device is submerged in liquid to a certain depth, the valve arrangement (5, 32) is influenced by the generated pressure to thereby open and let in liquid to the body (20) so that releasing takes place and releasing of the mechanism for which the releasing device is designed, occurs.
