Patent FI-874336-A (FI)
Inventor: RANTANEN ISTO
IPC: F24F13/08
Filed: 1987-10-02
Abstract: The invention relates to a flow lattice 10, which comprises a frame 11 and bars 12, which guide the air flow and are fixed to the frame 11, the flow lattice furthermore containing heat transmission elements 15 for melting snow flakes and similar particles. The flow lattice, in relation to the flow, comprises front first bars 13 and, in relation to the flow, rear second bars 14, each bar 14 comprising a collecting channel 18 and heat transmission elements 15, which are arranged in connection with the collecting channel 18 in question. When the air reaches the flow lattice 10, it first runs between the two first bars 13 (arrow L1) connected to a second bar 14 (arrow L2) to its collecting channel 18. In so doing the heat transfer elements 15 in the collecting channel 18 melt the snow flakes and similar particles arriving with the air as they strike the collecting channel 18 after having reached the heated parts of the collecting channel 18. In the flow lattice 10, the air is then moved from the collecting channel 18 from the space between (d2) a first bar 13 and a second bar 14 to the area (d3) between a second bar 14 and another second bar 14, which lies alongside this parallel thereto and away from the flow lattice 10. <IMAGE>

Abstract: The invention relates to a press roll in the press section of a paper machine or the like, which roll has a fixed body 1 and a shell 2 rotating on the body, the shell under the action of a separate counter-roll being compressed and sliding towards a concave slide shoe. At the ends of the roll there are elastic ends 4 rotating with the shell, changes in the shape of which ends compensate for the fact that the moving path and shape of the shell do not coincide with the rotational moving path and shape of the ends. This permits the use of relatively rigid shells 2. The shell may be shorter than the slide shoe. <IMAGE>

IPC: H04B1/707
Filed: 1995-12-18
Abstract: A system for determining the rate at which data has been encoded in the receiver (12) of a variable-rate communications system. The data is received in symbols that are grouped in frames. When data is transmitted at full rate, the frame is filled with symbols. When the data is transmitted at less than full rate, symbols are repeated within a frame until the frame is full or the symbols are spaced apart within a frame. At an encoding rate of one fourth the full rate, for example, each symbol in the frame is repeated four times or data is transmitted one quarter of the time. The incoming frames are decoded, for example by decoder (48), and re-encoded, for example by encoder (76), at each possible data rate. A comparator, for example comparator (84), compares the re-encoded symbols with the originally received symbols and a counter, for example counter (100), counts the number of symbol errors. Each decoding process produces an indication of the quality of the decoding process which may include Cyclic Redundancy Check (CRC) results, for example CRC (120), or Yamamoto Quality Metrics. The counted errors and the quality indication comprise an error metric which is passed to a processor, for example microprocessor (56). The processor analyzes the error metric for each data rate and determines the most probable rate at which the incoming symbols were encoded.

Title: A process for the removal of the oxide or salts of iron from zirconium compounds
IPC: C01G25/06
Filed: 1946-01-11
Abstract: Iron is removed from aqueous zirconium sulphate solutions having a pH below 7 by admixing with calcium ferrocyanide, preferably in solution, and removing the resulting precipitate. Calcium sulphate formed during precipitation helps to carry down silica and other insoluble matter.  The purified solution may be treated by the process of Specification 610,549 to produce basic zirconium sulphate which may be calcined to zirconium oxide.  The sulphate solution may be produced by calcining zirconium minerals or used refractories with lime and a little calcium halide, e.g. chloride in e.g. a muffle or rotary furnace at 1100-1250 DEG  C. for at least one hour, leaching with dilute hydrochloric acid and water, heating with strong sulphuric acid up to 250 DEG  C., and forming a slurry with water. Calcium silico-zirconate 3CaO.ZrO2.SiO2 is formed during the calcination.

Filed: 1921-01-10
Abstract: 157,261. Lundgaard, I. Sept. 21, 1915, [Convention date]. Refrigerating, cold-air machines for.-A coldair machine comprises a compressor-piston 13 and a displacement piston 11 arranged within a common cylinder 1, 3 communicating at each end with tubes 34 cooled externally, regenerator passages 36, and tubes 37 surrounded by the medium to be cooled, the air being circulated through these passages alternately in opposite directions. The compressor-piston is driven from a crankshaft 18 by a connecting-rod 22 in the form of arms mounted on bearings 23 carried by the piston, while the displacement piston 11, which is made of heat-insulating material such as rubber, celluloid, or fibre, is provided with a rod 16 passing through a stuffing-box 17 in the compressorpiston and connected to a lever 26 having a roller 28 engaged by a cam 29 on the crank-pin 21. The lever 26 carries a plate 32 bearing against a spring 30, which serves to return the displacement piston to its uppermost position, while yielding against resistance due to the formation of ice in the expansion-chamber 9 at the top of the cylinder. The air in the cylinder is compressed on the up-stroke of the piston 13, until the displacement piston 11 descends quickly under the action of the cam 29 and forces the air through a narrow channel 33 into the tubes 34. These are of flattened crosssection and are cooled by air, water, or other medium. The regenerating chamber is made of heat-insulating material such as fibre, and the narrow channel in it through which the circulating air flows is filled with a continuous coiled metal plate 39, Fig. 5, having overlapping slots, whereby the temperature of the air is lowered nearly to that of the upper set of tubes 37. The cooled compressed air passes through these upper tubes 37 and through a narrow channel 38 into the expansion chamber 9 and undergoes expansion while the two pistons move downwards together. On the quick return of the displacement piston the air is forced back through the tubes and regenerator passages to the compression-chamber. The cylinder 1 may be grooved as at 42 to prevent the entrance of moist air. One of the grooves may communicate with a receptacle containing calcium chloride or other drying-agent. The part 3 of the cylinder may be crimped over a flange 60 of the part 1, and the upper part 5 of the cylinder may be similarly attached to a flange 56 of the wall of the regenerator. The cover 6 may be welded to a flange of the part 5.

Title: Improvements in or relating to corrugated rubber hose
Inventor: WOODS EDGAR CHARLES
IPC: F16F9/04
Filed: 1957-01-14
Abstract: 825,084. Pneumatic springs. JOHN BULL RUBBER CO. Ltd. Jan. 13, 1958 [Jan. 14, 1957], No. 1347/57. Class 108(3) [Also in Group XXVIII] A rubber hose for a pneumatic suspension for road vehicles having circumferential corrugations comprises as a reinforcement at least two layers of a cord fabric applied to a vulvanizable rubber tube, the fabric having been so cut on the bias and applied with opposing bias to the tube that the layers are stretched during formation of the corrugations when manufacturing the hose (see also Group XXVIII). The circumferential corrugations may be normal to the axis of the hose or may be helically disposed A greater number of layers of cord fabric than two provided in pairs may be used. The cord fabric is similar to the fabric used in the construction of pneumatic tyres and consists of warp cords with very weak weft threads lightly to hold the warp cords together. Preferably the fabric is calendered on both sides with a rubber sheet and is then cut on the bias and the two plies of composite fabric are applied with opposite bias to the vulcanizable inner tube. Instead of the above cord fabric there may be used a weftless cord fabric produced by passing a number of single warp cords in parallel relationship through a calendar to form a sheet of material comprising the cords between two layers of rubber. The warp and/or weft may be of natural or synthetic fibres or admixtures thereof e.g. of cotton, linen, rayon, nylon and so on. The vulcanizable inner tube may be wound or applied on the mandrel or a strip of vulcanizable rubber may be shaped around the mandrel to form the tube The bias angle may be about 25 degrees or about 30 degrees. In Fig. 3 the inner vulcanizable tube is shown at 11 and the cord fabric layers at 12, 13. Around the layers 12, 13 is an outer vulcanizable rubber tube 14 having regions of greater wall thickness as at 15. The inner tube may be provided with thicker regions instead of or in addition to those shown at 15. The inflatable tube of Fig. 1 is stretched axially so that its diameter is reduced and thereafter it is inserted into the inner tube 11 and the ridges 21 are brought to lie beneath the regions 15. The inflatable tube is then blown up to a pressure of say 10 lbs./ sq.-in. The valley portions between the regions 15 are held against diameteral expansion Thus the regions 15 are increased in diameter. Thereafter the assembly is introduced into a curing mould 25, Fig. 5. While in this mould the inflatable tube is subjected to a pressure of about 100 lbs./ sq. in. so that the tube is corrugated as indicated at 26. While the tube is subjected to pressure it is vulcanized in the usual manner. The corrugated hose may be reinforced by providing a plurality of rings which closely lie within the valleys between the corrugations.
