Title: Soaking pit furnace and method of controlling it
IPC: C21D9/70
Filed: 1939-03-09
Abstract: 527,765. Ingot-heating furnaces. DEHN, F. B. (Amsler Morton International, Inc.). March 9, 1939, No. 7721. [Classes 51 (i) and 51 (ii)] In an ingot heating furnace of the kind described in Specification 491,814, the thermal input to the furnace is controlled by regulating the fuel supply during the initial stages of the heating cycle in accordance with the temperature prevailing at the top of the furnace and thereafter regulating the fuel supply in accordance with the temperature prevailing at the bottom of the furnace. The thermal input is first manually set at a predetermined rate and when the thermocouple 71 at the top of the furnace reaches the control point a recording potentiometer 51 energizes an electromagnet power unit 49 to actuate a valve 48 in the fuel supply pipe 46 to reduce the fuel supply. When the thermocouples 75, 76 at the bottom of the furnace indicate a predetermined temperature on the controller 52, a switch 77 is operated to connect this controller to the power unit 49 so that the fuel supply is controlled in accordance with the temperature at the bottom of the furnace. The correct ratio of the fuel supply through the pipe 46 and air supply by a blower 30 through pipe 31 is maintained by a regulator 45 which is operated by the differential pressures on opposite sides of orifice plates 60, 63 in the air and fuel supply pipes to control fluid pressure from pumps 56, 57 and pipe line 58 leading to the regulator 45 and from the regulator through pipes 43, 44 to a power cylinder 42 for actuating a valve 41 in the inlet to the blower 30. A regulator 39 is provided for maintaining a constant pressure in the furnace. This regulator is operated by pressure differentials in the furnace pressure sampling tube 67 and in a tube 69 connected to atmosphere and controls fluid pressure from the pumps 56, 57 and main 58 to pipes 37, 38 connected to the power cylinder 36 for adjusting the damper 35 in the stack flue.

Title: Rotary planographic printing unit
IPC: B41F7/30
Filed: 1978-02-27
Abstract: In the printing unit which has been converted from letterpress printing to lithoprinting, the damping medium is applied to a plate cylinder (1) via damping units (15, 25). Each one of the damping units (15, 25) consists of a damping medium dispenser (19, 27) in the form of a damping medium spraying source, by means of which very small droplets of damping medium are projected without contact onto the outer surfaces of forme damping rollers (17, 23). The forme damping rollers (17, 23) consist of a solid steel core with a rubber or synthetic coating which accepts damping medium and repels ink and has a storage effect. The forme damping roller (23) is arranged in the lithoprinting operation at the point where the forme inking roller was located in the letterpress printing operation. <IMAGE>

Abstract: 862,783. Mine-roof supports. VANWERSCH, P., VANWERSCH, L., and VANWERSCH, A. March 6, 1959 [March 6, 1958], No. 7948/59. Class 20(2) A connection for tongue-and-fork roof support bars 1, 2 which are symmetrical about a horizontal mid-section, is erected by inserting a pivot pin 3 into holes in the fork and into a slot 5 in the tongue and by engaging one of the wedging surfaces 6 on a non-rotating slide 4 with the tongue. When the slide is in 'mid' position, the region 8 provides clearance for the tongue to enable the bar 1 to be swung into or down from a near-horizontal position. A modified arrangement (Figs. 6, 7, 8, not shown) uses a plain hole for the pin 3 in the tongue and an auxiliary pivot pin to assist in aligning the bars to insert the main pin 3; the arrangement also allows a continuous straight line to be maintained over the upper surfaces on the bars and their joint.

Abstract: 660,911. Glass composition. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FILS. March 24, 1949 [April 23, 1948], No. 8037/49. Class 56 A glass consists of 45-50 per cent SiO 2 , 8-12 per cent K 2 O, 30-36 per cent CaO+ SrO+BaO, 0-3 per cent MgO, 4-7 per cent B 2 O 3 , and 0-1 per cent various, with the complete absence of Na 2 O, Al 2 O 3 , ZnO, and PbO. The dielectric losses of the glasses decrease when the frequency increases, and the glasses may therefore be used in most radio applications where very high frequency currents are involved, and are particularly intended for high frequency valves. An example containing 48.3 per cent SiO 2 , 9 per cent K 2 O, 3 per cent CaO, 32 per cent BaO, 2 per cent MgO, 5.1 per cent B 2 O 3 , 0.6 per cent As 2 O 3  has a resistivity at 200‹ C. of 10" ohms per sq. cm. per cm., a volume resistivity of 100 megohms per sq. cm. per cm. at 452‹ C., dielectric loss coefficient (tan #) for 1 megacycle 12x10<SP>-4</SP> and for 10 megocycles 7x10<SP>-4</SP>, coefficient of expansion 95x10<SP>-7</SP>, and solubility in water (powder method) 28 mgm.

Title: Method of distributing particles over a surface
IPC: B24D18/00
Filed: 1953-03-24
Abstract: 720,844. Particle-coated paper and fabric. BOART PRODUCTS, SOUTH AFRICA, Ltd. March 24, 1953 [Oct. 15, 1952], No. 8140/53. Class 140. [Also in Groups XV, XXIII and XL (a)] A method of coating a surface with a single layer of particles comprises the steps of coating the surface with an adhesive, making a mixture of the particles with auxiliary particles which are convertible into a fluid state, covering the adhesive coated surface with the mixture, removing any excess mixture, allowing the adhesive to set sufficiently to hold all the particles in contact with it, and removing the auxiliary particles by selectively converting them into a fluid state. Uniform spacing and controlled density of coverage are thus obtained. The main particles may be abrasive, e.g. diamond boart, or luminescent. The auxiliary particles may be of approximately the same size as the main particles or, where a high percentage of coverage is desired, of smaller size. The two powders are mixed in the desired proportions, the auxiliary particles may be coloured, e.g. by a dye so that a visual indication of the thoroughness of mixing is obtained. The auxiliary particles may be water soluble, e.g. rock salt, and removed by solution in water. The auxiliary particles may be crushed ice or " dry ice " (CO 2 ), the mixing and application of the particles being carried out at reduced temperatures; the auxiliary particles are removed by raising the temperature, thus causing the ice to melt or the dry ice to sublimate. The method may be used for securing abrasive grains 15, Fig. 2, to a backing 18 of paper or fabric.

Complex formation is effected either by dehydrating before adding the dicarboxylic acid and/or by adding the Li base stepwise. In one embodiment the Li soap (a) is formed in situ in the lubricating oil and then dehydrated before adding the dicarboxylic acid. The final composition is dehydrated (e.g. at 280-300‹ F.) and may then be heated at 380- 400‹ F. for 15-60 mins. to ensure optimum soap dispersion.

Abstract: 728,455. Cemented pile fabrics. BIGELOWSANFORD CARPET CO., Inc. April 7, 1952, No. 8808/52. Class 142(4). Pile material is formed into corrugations and fed to a backing covered with adhesive, each alternate bight of the corrugations being secured to the backing by pressure and heat supplied by an electrode. The backing 1 is fed through a bath of adhesive 68 and over a lower electrode 7. Pile material is fed between upper and lower grippers 45, 43 respectively which advance the pile against an upper electrode 8 to form a corrugation. The electrode is raised and the backing is simultaneously drawn forward by a spiked roller 3. The electrode is then lowered and presses the pile on to the adhesive. The electrode is moved by a linkage comprising members 70 ... 78 and a cam 69 on the main shaft 12. The grippers are moved to advance the pile material by an eccentric 29 on the shaft 12 and by members 31 ...35, the member 35 being connected to a block 38 carrying the grippers. A cam 46 and linkage 49 ... 53 opens the grippers. The roller 3 is rotated by a pawl and ratchet 17, 18, the pawl being moved by a cam 11 and a linkage 13-16. A roller 20 with a rubber covering 21 presses the fabric on to the roller 3. The backing may be of burlap or paper ; the pile may be of felt, sliver or yarns and may be of wool. The lower end of the electrode 8 may be grooved to form a ridge of adhesive. The adhesive may be thermoplastic or thermosetting or may be a plastisol paste; it may be a compound of polyvinyl acetate, urea-formaldehyde, or phenol formaldehyde resin. A thermoplastic-thermosetting resin adhesive may be used. The adhesive may also be in powder form.
