Title: Continuous casting  apparatus
IPC: B22D11/06
Filed: 1971-01-06
Abstract: 1341784 Continuous casting I PROPERZI 6 Jan 1971 [14 Jan 1970] 680/71 Heading B3F In a wheel-and-belt continuous casting machine, idle rollers 19, 20, Fig. 5 (for guiding the belt 4 at the periphery of the wheel 2) and a casting-withdrawal unit 21 are supported on a frame 22 which can be swung about the wheel shaft 26, Fig. 6, to a selected angular position before securement (by bolts 24a) relative to the machine base 1; correspondingly a pulley 5, Fig. 10, for the belt 4 can be set at a number of angular positions about the shaft 26 while a tundish 10 can be mounted in a number of positions around the wheel 2 to determine the direction A of pouring. The direction A, since the tundish nozzle 11 can be moved, may thus be varied from horizontal, Fig. 10, to the vertical, Fig. 5, with corresponding adjustment of the position of the rollers 19, 20 and withdrawal unit 21 and of the length of the belt 4. The withdrawal unit 21 is mounted on the adjustable frame 22 to move with it and has a motor (30) which can move the unit 21 to or from the casting wheel. The roller 20 can be swung away from the wheel 2 on an arm 31, on the adjustable frame 22, by a cylinder 33. The roller 19 is also mounted on an arm 38, on a slide 35 movable by a fluid-operated motor 36 on the frame 22 along guides on the frame. The arm 38 is adjusted by a fluid-operated motor or cylinder or by a handwheel 40 by way of a spring-loaded rod 44.  The pulley 5 can be mounted in a number of positions along a beam 7 which itself can be mounted at different positions along its length on a pillar 9. Two cooling assemblies 47 with nozzles 47a, 47b for the belt 4 and wheel 2 are mounted on the adjustable frame 22 for positioning thereby and may also be radially moved by cylinders 51, Fig. 6, on the frame. A manifold 29b (with nozzles 29 for cooling the rim of wheel 2 from inside) can be swung about the wheel axis for adjustment when a water conduit 28 in the wheel shaft 26 is released for manual rotation (and then re-secured) by the loosening (and then tightening) of screws 28a threaded in the machine frame. The tundish 10 could be connected to the adjustable frame 22 but is shown mounted in a yoke 12 movable by motor (14) vertically along a bracket 13 which is movable parallel to the wheel axis by motor (17) along a slide 15 in turn movable normal to the axis along horizontal guides (16) by motor 18.

Title: Improvements in or relating to absorption refrigerating systems
IPC: F25B15/10
Filed: 1928-01-09
Abstract: 283,473. Electrolux, Ltd., (Assignees of Lenning, A.). Jan. 8, 1927, [Convention date]. Refrigerating, absorption machines and systems for.-In continuous-cycle systems containing a pressure-equalizing inert gas, a circulation of the refrigerant and inert gas mixture upwards through the absorber, and of the inert gas upwards through the evaporator, both in counterflow to the respective liquids, is effected automatically after a short starting period during which the circulation is the reverse of the desired counterflow direction. In the arrangement shown, the evaporator 20 is located at a higher level than the absorber 27 and these vessels are connected by conduits 19 and 24, 26 formed into a heat exchanger 25 for the gases. The generator 10 is divided by a partition 11 into two parts 12, 13 connected by a riser pipe 16, and is provided with a central flue 14 for the heating means 15. The strong liquor flows from the absorber through a pipe 34 and interchanger 36 to the lower compartment 13 of the generator and the weak liquor is returned from the upper compartment 12 through a pipe 35, 37 which makes one turn within the cooling-jacket 29 of the absorber before entering the latter at the top. The ammonia or other refrigerant gas rises from the generator through a pipe 17, down which any condensed water vapour may return, and passes through a water-cooled condenser 18 and a pipe 17<1> leading through the conduit 19 to the upper part of the evaporator. A vent pipe 41 for gas is provided at the condenser outlet. The absorber and evaporator are fitted with plates 21 having staggered openings 22 with upstanding rims 23, and a pipe 38 formed into a seal extends from the bottom cf the evaporator to the conduit 19. At starting, the refrigerant and inert gas mixture formed in the evaporator flows downwards through the passage 24, exchanger 25 and pipe 26 to the absorber, and the inert gas (hydrogen) flows upwards through the conduit 19 to the top of the evaporator. Owing to incomplete diffusion of the inert gas into the refrigerant, the latter tends to reach the bottom of the evaporator still in a liquefied condition, and eventually flows through the seal 38 into the conduit 10, where it first creates a resistance to upward flow and then evaporates. The mixture thus formed descends owing to its density, and flows upwards through the absorber, while the inert gas passes from the absorber through the conduit 26, exchanger 23 and conduit 24 and upwards through the evaporator. This direction of flow will persist, and any liquefied refrigerant passing through pipe 38 will in conduit 19 and serve as a cooling medium for the gases in the exchanger. Any liquid carried from the absorber to the exchanger 25 passes back through a small hole 40 in the pipe 19. A modifed gas heat exchanger is described wherein a conduit open to the space 25 extends through the pipe 19.

Title: A process for the separation of the crude resin obtained by extraction from kauri timber into light and dark coloured resinous products and apparatus therefor
IPC: C09F1/00
Filed: 1933-02-09
Abstract: Crude resin obtained by extraction from Kauri timber with a solvent such as alcohol is purified by heating with a mixture of ethyl acetate and benzol or benzene.  The crude resin, preferably powdered, is introduced into a tank 1, the solvent mixture run in from a tank 7 through a pipe 8, and heat is applied by means of a steam jacket 2 while stirring mechanism 5 is operated.  When extraction is completed and the stirrer stopped, the clear solution is led off by pipes 17 through a cooler 18 to a tank 19 where the solution is agitated with a dilute alkali such as ammonia introduced through a pipe 26 from a tank 27.  The alkali-treated solution flows through pipes 30 to a vessel 31 where it is treated with water introduced through a pipe 36 and perforated plate 35 while stirring.  The washed solution is passed through a filter 43 to a still 44 where the solvent is distilled off.  The molten, purified resin is blown with air in the still to raise the melting point.  The sludge left in tank 1 is passed through a steam-jacketted pipe 15 to a still 16, to which also is led the precipitate produced in the alkali treatment tank 19, and, if desired, the washings from the vessel 31.  Solvent distilled off in still 44 is condensed in condenser 12 and returned to tank 7 through pipe 13.  The solvent distilled off in still 16, evaporated in tank 1, or driven fff from tank 19 when empty by the admission of steam at 23, is condensed in condenser 11 and returned to tank 7 by way of a water separator 10.  The alkali-treatment tank 19, and washing vessel 31 may be <PICT:0414716/III/1> replaced by a single vessel into which first alkali, then water, are admitted through a distributing spray; a reflux condenser may be introduced into the vapour pipe 52 from still 16 having an outlet leading to the alkali tank 27 for the purpose of recovering ammonia before the solvent vapours are condensed in condenser 11; in the treatment of crude resin from hill timber, the treatment with alkali may be omitted, the washing with water may take place in the extraction vessel 1 instead of in a separate tank, and two or more extraction vessels may be employed to obtain continuous operation of the plant.  The apparatus, or parts thereof, are made of stainless steel, aluminium, or other material unaffected by the resin.  The Specification as open to inspection under Sect. 91 describes also the use of benzol alone as the treating liquid.  This subject-matter does not appear in the Specification as accepted.

Title: Continuous hot dip galvanizing of metal strip
IPC: C23C2/22
Filed: 1956-01-10
Abstract: 785.265. Coating by dipping. WHEELING STEEL CORPORATION. Jan. 10 1956 [Aug. 19, 1955], No. 810/56. Class 82(2) Metal strip is hot dip galvanized and the coating thickness controlled and maintained uniform by controlling the speed of the exit rolls so that the exit rolls slip against the strip. In an embodiment as shown in the Figure the strip (6) is passed vertically out of the molten bath between exit rolls (4) whose axes are parallel and lie approximately in the surface (3) of the coating metal (spelter). The speed of the exit rolls is regulated to inhibit the movement of spelter upwardly between the rolls, particularly by running the rolls at a speed such that their peripheral velocity next to the strip is less than the velocity of the strip. For very high speeds, when a thin coating is applied, the. exit rolls may be driven in reverse or maintained stationary. The strip may be engaged by other rolls (7), (8), before the strip reaches the exit rolls, to inhibit the tendency of the spelter to cling to the strip by capillary action. One of the rolls (7) may have its axis positively located and the other (8) be resiliently urged towards it, e.g. by mounting on a swinging arm (9) attached to a weight (13) (which may be movable) and pivoting at (10). The faces of the rolls may be resistant to wetting by the spelter. The spelter may be all zinc or have additions of any of the aluminium. lead, antimony, cadmium and tin.

Abstract: 538,598. Copying documents. KORESKA, W. Jan. 15, 1940, No. 904. Convention date, Jan. 17, 1939. [Class 100 (ii)] [Also m Group III] In a rotary duplicating machine, the damping roller is moistened by an absorbent strip extending into a container supplied with excess liquid to keep the strip saturated the excess flowing over an overflow edge into a reservoir. In one form, Fig. 1, the absorbent strip 25 is carried by a chamber 26 having a false bottom 27 which with end walls 28, 29 and the side walls of the chamber 26 forms a shallow liquid container. Excess liquid flows over the edge 28 into a reservoir 31. The liquid is supplied to the container from the reservoir 31 by an endless wick 33 passing between a freely mounted roller 32 and a driven roller 34 which squeezes liquid from the wick through slots 37 in the roller 32.' A conical extension 35 of the roller 32 and an internal conical projection 36 are formed with grooves to conduct liquid pressed out from the wick into the container. When the machine is stopped the liquid in the container flows through an outlet in the end wall 29 on to the bottom of the chamber 26 and thence into the reservoir. In a second form, Fig. 5, liquid flows directly from a reservoir 48 through a tube 49 to a container 42 having an overflow edge at one end above tank 51. A second absorbent strip 44 pressed into contact with the damping roller by an adjustable spring 47 and bar 46, regulates the amount of liquid applied by the roller to the copy sheets. The Specification, as open to inspection under Sect: 91 comprises also an improved means for driving the duplicator and operating the master sheet gripping device. This subject-matter does not appear in the Specification as accepted but forms the subject-matter of Specification 538,114.

Title: Heat pump
IPC: F24D3/18
Filed: 1959-01-10
Abstract: 894,011. Refrigerating; heat pumps. WISEMAN, A. R. A. April 8, 1960 [Jan. 10, 1959], No. 982/59. Class 29. In a heat pump of the compression type for heating domestic air or water, the evaporator, at normal ambient temperature, is heated by ambient air but, at reduced ambient temperatures, a second stage operating at lower temperature levels is brought into operation by a thermostat responsive to ambient temperature, and heats the first stage evaporator. As shown in Fig. 1, two compression systems are in cascade, the condenser R1 of the upper stage being located within the building, the compressor C2 of the lower stage being controlled by ambient temperature, and the heat exchanger constituted by the evaporator El and the condenser R2 being so constructed that the former can receive heat either from the latter or from ambient air. In a modification, evaporator El comprises two sections in series in heat exchange respectively with ambient air and condenser R2. The low temperature evaporator may be defrosted by water, hot gas, electric heating, vibration or mechanical deformation. More than two stages may be provided. The compressors may be driven by J.C. engines, the waste heat of which augments the heat pump effect. According to the Provisional Specification, at high ambient temperatures, refrigerant is evaporated in a high temperature evaporator heated by ambient air and compressed by a first compressor; at low ambient temperatures, a second compressor is also energized and liquid refrigerant not evaporated in the high temperature evaporator is evaporated in a second evaporator operating at lower pressure and is compressed by the two compressors in series. Superheat is removed from the vapour compressed by the second compressor in interstage coils by bleeding liquid refrigerant from the condenser through an auxiliary expansion valve.
