Patent GB-346753-A (GB)
IPC: C10C1/04
Filed: 1930-01-10
Abstract: <PICT:0346753/III/1> <PICT:0346753/III/2> Hydrocarbons, distilling.--Tar is distilled by direct contact with a stream of highlyheated gases, e.g. hot coal-gas from a coke oven battery to give a high melting point pitch, and the hot gases are then passed into indirect contact with a second supply of tar, the tar being thereby distilled to give a low melting point pitch and the oil content of the hot gases condensed to give a light distillate.  A battery of coke ovens 3 of usual construction is provided with up-take pipes N leading into an insulated still 10 continuously supplied with tar from a pipe 15 and provided with a rotating roll 12 at one side of the still which sprays the tar into intimate contact with the hot gases entering through the up-take pipes 11.  The pitch produced is continuously removed through a drawoff 16 and is granulated by spraying with water. The hot gases and vapours pass off through a settling chamber 19 into a heat-exchanger 21 containing coiled tubing 24 through which the second supply of tar is passed, the heated tar being flashed in a chamber 34 and the vapours evolved condensed in a condenser 38, while the low melting pitch collecting in the base of the chamber 34 is passed through a pipe 35 to a receiver 36.  The condensate formed by the cooling of the gases in the chamber 21 is passed to a receiver 26 while the gases are led to a scrubber 28 where residual vapours are condensed by spraying with water.  In the modification shown in Fig. 5 the gases from the coke ovens are first passed to an insulated header 61 where they are well mixed before entering the still, and the tar to be distilled is sprayed into the separating chamber 58 and thence through an insulated pipe 53 to the still 52.  The hot gases and vapours leaving the still pass through two heat exchangers where they heat tar passing through the coils 64, 65 in series, the tar finally being led through an insulated pipe 73 to a flushing chamber 74 and the vapours formed being condensed in a condenser 75.  In this modification the flushing chamber 74 is kept under reduced pressure by a vacuum pump 76 and is provided with a barometric column 78 through which the low melting point pitch is withdrawn. In the first still a pitch of melting point about 400 DEG  F. is obtained and the gases leaving this still at about 250-400 DEG  C. distil the tar in the heat exchanger to give a pitch of melting point 110-150 DEG  F. Specification 347,240 is referred to.

Title: Improvements in or relating to heat exchange devices
IPC: B23K1/00

Abstract: 577,979. Making heat exchangers. COLTMAN, J. L., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 19, 1943, No. 986. [Classes 83 (ii) and 83 (iv)] Soldering.-In making heat exchange devices, such as intercoolers, radiators or oil coolers for internal-combustion engines, of the kind having primary and secondary heat exchange surfaces formed of thin-walled copper or copper alloy sheet, strip or tubular elements by coating the parts with silver and heating in a non-oxidising or reducing atmosphere above 780‹ C. so as to form a silver-copper eutectic which solders the parts together, only one of each pair of contacting surfaces is so coated and the coating is limited to a thickness not exceeding 0.0002" and the surfaces are held in mutual contact under pressure during the soldering operation. The silver coating, which may be 0.0001"- 0.00015" and preferably not less than 0.000075" thick may be applied by coating a copper billet on one or both sides with a thin sheet of silver, rolling to sheet or strip form and then forming into heat-exchange elements, or by electro-depositing the silver on a sheet or strip or applying a paste of silver powder in collodion, or the coating may be effected during or subsequent to formation of the elements. Elements left uncoated or only coated on one side should be formed of deoxidised or oxygen-free copper or copper alloy. For a heat exchanger comprising alternate plain and corrugated platelike elements, the plain elements may be coated on both sides and the corrugated elements left uncoated. For a finned tube heat exchanger, the tubes, which extend through flanged apertures in the fins and are reinforced internally by stiffening members, may be coated internally and externally or. only internally, in which latter case the fin elements are also coated on one side. The parts are held in mutual contact when joining plain and corrugated elements by an earthenware tile or like. When elements are sufficiently resilient they may be assembled under initial compression in a jig. When joining fins to flattened tubes threaded therethrough, the flanges of the apertures in the fin elements may be radiused so as to exert resilient pressure on the walls of the tube. Soldering may be effected in a furnace containing an atmosphere of nitrogen or hydrogen or a mixture thereof formed by admixing the gases or by employing dissociated or cracked or cracked and burnt ammonia. Alternatively, the atmosphere may comprise carbon dioxide or burnt coal gas or like hydrogen gases. In joining flattened tubes to corrugated strips of deoxidised copper, the tubes may be coated on both sides with a layer of silver 0.00015" in thickness and the parts assembled in a jig and soldered at 820‹ C. in an atmosphere of cracked ammonia. Specifications 540,961 and 548,515 are referred to.

Title: Electric coffee percolator
Inventor: PANDOLFI ALBERTO
IPC: G01F1/06
Filed: 1980-04-02
Abstract: A primary component (MV) rotated by the water flow, converts a series of angular offsets into an electronic pulse train (TR). The pulses are added in a summing circuit. An electronic comparator circuit, with a programmable and adjustable threshold, transmits an analog signal when a preset threshold has been attained in the summing circuit. - The analog signal actuates an electric three-way valve (EL) in such manner that it moves from a first position supplying the coffee brewing water, into a second position interrupting the flow and connecting the machine to ambient air. Pref. an opto-electronic paddle wheel forms the primary component. Alternately, it is in the form of a proximity switch. A resetting feedback may be used for automatic zeroing of the summing circuit after a finished coffee machine cycle.

IPC: F16L1/00
Filed: 1991-01-07
Abstract: PURPOSE:To expand the diameter of a spiral pipe smoothly by increasing the detaching speed of a wire rod from the spiral pipe when driving force given to a beltlike body reaches a preset ceiling value when the diameter of the spiral pipe is expanded. CONSTITUTION:When the diameter of a spiral pipe is expanded and fast stuck onto the inner circumferential surface of a sewer pipe 81 and a beltlike wire rod 30 is detached positively from the spiral pipe, a beltlike wire-rod detaching tool 40 disposed into the spiral pipe is used. The beltlike wire-rod detaching tool 40 is abutted against the inner circumferential surface of the spiral pipe and draws the beltlike wire rod 30 in the detaching direction of the beltlike wire rod 30. The beltlike wire rod 30 detached is wound by a winder 50 arranged on the ground through a roller 51 disposed into a manhole. When a beltlike body 10 is propelled while the beltlike wire rod 30 is separated from the spiral pipe, the outside diameter of the spiral pipe is brought to the state, in which the spiral pipe is formed to a truncated cone shape in succession and brought into contact with the inner circumferential surface of the sewer pipe 81, from the state sufficiently small to the sewer pipe 1.

Title: Mis-convergence correction coil for deflection yoke
Inventor: YAMAZAKI KOICHI
IPC: H01J29/76
Filed: 1994-01-06
Abstract: PURPOSE:To provide two kinds of functions of correction coils by using a PQH- PQV correction coil so as to generate a local magnetic field on four diagonals of a deflection yoke, leaving mis-convergence nearly as it is in the midpoint and correcting the mis-convergence for surrounding corners in PQV positive cross and PQH under directions. CONSTITUTION:A middle FC coil 8 is operated in a direction to pull up a magnetic field vertically similarly to the case with a conventional FC coil and horizontal end winding PQH, PQV correction coils 1, 2, 3, 4 are acted in a direction of pushing back the magnetic field. Thus, one set of mis-convergence correction coils comprising the upper and lower FC coils 8 and the left and right PQH, PQV correction coils 1, 2, 3, 4 has both functions of the FC coil and the PQH, PQV coils. Thus, correction effect is caused only to a circumferential part of the screen and reactive current is cut off to improve the correction efficiency.
