Filed: 1958-01-08
Abstract: 822,220. Nuclear reactors. ALLMANNA SVENSKA ELEKTRISKA A.B. Jan. 8, 1958 [Jan. 10, 1957], No. 716/58. Class 39(4). A nuclear fuel element cooled by high pressure fluid comprises rods 1 of uranium or thorium contained in a thin pipe 8 and is located within a pressure-resisting pipe 3 of the reactor, there being a heatinsulating space between the rods 1 and the pipe 3. The coolant, CO 2  at 30-100 atmospheres pressure, flows in at 13, down between thin pipes 9 and 10 and up over the rods 1 within the pipe 8. The pipes 8, 9 are joined at one end only and thus contain stagnant coolant forming one heatinsulating space. The pipe 10 is provided with one or more fine holes so that the space between this pipe and the pipe 3 also contains stagnant coolant and forms a second heatinsulating space. In this way the pipe 3 can be of magnesium protected by a layer of aluminium 12 as the water moderator 5 with which it is in contact is maintained at a low temperature. The pipes 8, 9 and 10 are of steel but are thin and absorb few neutrons. Specification 754,183 is referred to.

Title: Improvements in and relating to explosives
IPC: F42B3/087
Filed: 1959-01-09
Abstract: 866,620. Blasting devices and explosive compositions therefor. UNION CARBIDE CORPORATION. Jan. 9, 1959 [Jan. 13, 1958], No. 867/59. Classes 9(1), 9(2) and 68(1). A blasting device comprises a water-impervious flexible plastic tube 21 containing ammonium nitrate coated with a waterproofing agent and enclosed by an outer plastic tube 22, which is weighted at the bottom. The explosive is fed into the tube after the tube has been lowered into a borehole. To facilitate charging of the casing the tubing assembly is provided with an inner tube 20 which is used to inflate the tube 21. The composite tube, made from material such as polyethylene, polyethylene terephthalate, or polyvinylidene chloride, may be made up in uniform lengths or wound on a reel for shipment. To use the tubing, 1 - 2 ft. of the outer tube 22 is turned back to expose the tube 21, the exposed length of tubes 20 and 21 being then cut off near the fold. Notches 26 are made near the end of tube 20 before heat-sealing the cut ends of tubes 20, 21 together. The outer tube 22 is then straightened and a seal 28 is made below the seal 27 to form a pocket 29 in which ballast 32 or a soluble material is placed before the pocket is closed by a cord 33. Preferably a cord 34 is placed around the seal 28 and its ends 35 used to lower the tubes into a borehole after the tubing has been folded along its length and secured by bands of paper, or tape or by adhesive. Excess water is removed from the borehole or if the hole is dry a limited quantity of water may be introduced to obviate air pockets. The upper edges of tubes 21, 22 are drawn together around a plug 37 and clamped by a ring 38, which may have support legs 39. The inner tube 20 extends through a hole 41 in the plug, a relief valve 44 is fitted into a hole 45 and a charging funnel 42 is placed in a hole 43. Compressed gas forced into the tube 20 escapes through the notches 26 and inflates the tubes 21, 22 until they are fully expanded. The explosive 47 is then fed in through funnel 42, primer cartridges 48, which may be provided with fuzes 49 engaging notches in the plug 37, being introduced at intervals during the charging process. The inner tube 20 may be pulled out and the upper part of the tubes 21, 22 tied off as in Fig. 9 before the borehole is stemmed. The ammonium nitrate is coated with a liquid hydro-carbon in which a metallic soap is dissolved. In an example, an aluminium soap of 2-hexoic acid compound was dissolved in kerosene in the proportions of 7¢ parts by weight of soap to 100 parts kerosene, 1 gallon of the solution being added to about 80 1bs. of ammonium nitrate. Instead of aluminium soap, colloidal carbon blacks, colloidal silicas and mineral waxes may be used as gelling agents. The pocket 29 may be punctured to allow water to seep between the ballast granules or, if a water-soluble ballast such as a metal salt is used, to dissolve the salt, so that the explosive sinks to the bottom of the borehole.

Title: Instrument for inspecting surface of substrate and method thereof
Inventor: TAKAHASHI MASAYASU
IPC: G01N21/84
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To enable judgement of foul on the surface of a substrate by making steam hit the surface of the substrate as generated by the combustion of pure oxygen and pure hydrogen to generate a dew condensation image on the surface of the substrate. SOLUTION: The surface of a substrate 11 is inclined being depressed by 30-40 from verticality and the distance is maintained properly, for example, at about 20cm between a flame and the substrate 11 to make steam rising from a combustion nozzle 1 hit the substrate 11. The diameter of a water drop to the surface of the substrate 11 is almost below 30m, which is appropriate for the inspection of the surface. A dew condensation image pattern 12 as caused by a fine water drop condensed on the surface of the substrate 11 is recognized visually or with a camera to judge the presence of foul.  This eliminates dripping of water and a part where high humidity air current is led, thereby getting rid of possible breeding bed for mill dews and bacteria and also, a higher temperature of generated steam causes a larger temperature difference between the steam and the substrate 11, thereby causing a dew condensation on the surface of the substrate 11 especially without cooling the substrate 11.

Title: Base band two-way simultaneous transmission circuit
Inventor: HOSODA NAOKI
IPC: H04L5/14
Filed: 1980-01-08
Abstract: PURPOSE:To realize a full double communication via a piece of transmission line, by securing a connection among two pairs of opposing transmission/reception circuits via a piece of transmission line and then performing a logic decision by receiving the transmission signal of the remote side. CONSTITUTION:The output of the transmission circuit 1 in the communication device 4 is sent to the opposite communication device 4 via the resistance 8 and the transmission line 3. The output of the circuit 1 is also compounded with the reference voltage 7 via the partial pressure resistances 9 and 10 to be then supplied to the reference input of the comparator 6. Then the reception signal supplied from the remote side is led into the +input of the comparator 6. Thus the comparator 6 detects the level variation of the reception signal given from the remote side regardless of the transmission signal of the own device.

Title: Image processing unit and image processing method
Inventor: SUZUKI YUZURU
IPC: H04N1/409
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To reproduce an image in which line drawing characters and medium tone photographs are in existence in mixture with high image quality. SOLUTION: An image area separate discrimination section 30 identifies whether received image data are a character area or a photographic area and generates a 1st area data signal S1 to identify whether the data are a black character or a color area. Compression sections 25a-25d compress the image data and the resulting data are stored in image memories 26a-26d. On the other hand, a compression section 31 compresses the resolution of the 1st area data signal S1 and stores the result to an area memory 32. Image area separate discrimination sections 34a-34d generates again a 2nd area data signal S2 by a different system from the image separate discrimination section 30 based on expanded image data. Again the 2nd area data signal S2 is generated.  Tone correction sections 28a-28d and SG sections 29a-29d apply prescribed image processing to the image data expanded based on the 1st area data signal S1 and the 2nd area data signal S2.

Title: Sequential supervisory control device
Inventor: HAYAKAWA MITSUMASA
IPC: G05B19/02
Filed: 1985-01-08
Abstract: PURPOSE:To attain start/stop in a series of sequences by forming a storage device for storing the current value of a sequence advancing timing and advancing the sequence on the basis of the formation of the current value and the succeeding sequence advancing timing. CONSTITUTION:A counter K is used as the storage device. The counter K is turned to the using state at the formation of a sequence timing signal Z-1, and when AND logic 10 between the signal Z-1 and the initial value '0' of the counter K is formed, the counting value of the counter K is turned to '1' through an OR logic 20. The counting value is turned to '2' at the formation of a sequence timing signal Z-2, and similarly, the counting value is turned to '3' at the formation of a sequence timing signal Z-3. Even if the sequence timing signal is returned from Z-2 to Z-1, the counting value is not counted up. A condition for counting up the counter K is obtained by AND between the formation of the sequence timing and the contents of the counter K at the prestage of the timing formation in addition to the formation of the sequence timing.
