Title: Process for manufacturing briquettes
IPC: C10L5/04
Filed: 1955-04-18
Abstract: 768,910. Fuel briquettes. STAMICARBON N.V. April 18, 1955 [April 22, 1954], No. 11175/55. Class 50. In a process for forming briquettes from a mixture of a material which softens on being heated to a certain temperature, e.g. bituminous coal, and particles of a material which does not soften at that temperature, e.g. coke breeze, by pressing the mixed particles together while the softening particles are in a softened condition, the softening and inert particles are fed into and intimately mixed in a carrier gas stream and then separated from the gas and pressed together for forming the briquette, the carrier gas and/or at least some of the inert particles having been preheated to such an extent that the temperature of the softening particles is rapidly raised by heat exchange. In Fig. 1 a hot carrier gas is formed in a combustion chamber 4 by burning gas with air and the hot gases, e.g. at 900‹ C., pass along an insulated pipe 1 into which coke breeze and bituminous fuel coal (temperature of maximum softening about 420‹ C.) are fed from bunkers 5 and 6 respectively so that a mixture is obtained in the cyclone separator 2 containing 70-80 per cent by weight of coke breeze and 20-30 per cent by weight of bituminous fine coal. The mixture passes out of cyclone 2 through a briquetting press 3. In the modification shown in Fig. 2 an inert carrier gas is passed along the pipe 1 and heated coke breeze is fed into the carrier from a bunker 8 in which the breeze is partially combusted as a fluidized bed. In further modifications a mixture of coke breeze and bituminous fine coal is fed into a hot carrier gas and a quantity of heated coke breeze is added adjacent the point of entry to the cyclone separator. In another arrangement heated coke breeze is fed into a carrier gas in two stages, one preceding and one following the feeding in of the bituminous fine coal. The flow rate of the carrier gas is preferably about 20 m./sec.

Abstract: 1,038,902. Feeding webs. TUDOR, A.B. March 18, 1964, No. 11391/64. Heading B6B. [Also in Division C3] A web 3 is guided and fed through a treatment zone defined by a tube I of rectangular crosssection open at both ends, by the treatment medium, of gas or liquid, which enters the tube 1 via a conduit 2 with sufficient velocity and pressure to substantially fill the tube 1. An oscillating pressure develops between the walls of the tube 1 and the web of material 3, so that the web is supported, i.e. guided along a central path within the tube, as shown. The conduit 2 enters the tube 1 nearer to one end of the tube than the other end, and the web of material is advanced in the direction of the longer length of tube. The apparatus may be used to dissolve a soluble filling material in a synthetic plastic web, thereby providing the web with a degree of porosity. The treatment medium in this case is water.

Title: Buttonhole sewing machine
IPC: D05B3/08
Filed: 1941-09-06
Abstract: 549,563. Sewing-machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.). Sept. 6, 1941. No. 11420. [Class 112] In a button-hole sewing-machine such as that described in Specification 549,425 a moving cutter 191 co-operates with a fixed cutter 189 to cut the needle thread above the work and with a cover plate 200 to grip the supply end of the cut thread. The devices are carried on a sleeve 203 mounted in the end of a lever 204 with a fixed pivot 205. The sleeve 203 also carries a plate lever 210 having a cam-slot 211 in which rides a fixed pin 212. Accordingly, the cutters are tilted as the lever 204 moves and the operating point traverses an upwardly convex curved path. The cutter 191 is coupled at 196 to a slide 194 urged by a spring to closed-cutter position. The slide is moved to open the cutters by a lever 214 on a shaft 213 within the sleeve 203 and an arm 216 on the shaft carries a latch 221 of which the tail 217 on the upward movement passes a fixed projection 218 but on the downward movement is used to force the lever 216 anti-clockwise and through the lever 214 depress the slide 194 and momentarily open the cutters. The lever 204 is operated by a cam on the pattern shaft at the close of the stitching operation and before the movement to the initial or button-hole cutting position. The return movement of the lever 204 brings the lever 214 into contact with a stop 223 and a slight further upward movement produced by the actuating cam before the initial stitch of a new button-hole causes release of the thread. The needle thread tension is taken off by the pattern cam at the completion of one button-hole and a thread pull-off is actuated by the clamp-closing lever before the release of the thread end at the commencement of another.

Title: Pressure cycle for molecular sieve separation of normal paraffins from hydrocarbon mixtures
IPC: C07C7/13
Filed: 1960-04-01
Abstract: Normal paraffins are separated from hydrocarbon mixtures containing four or more carbon atoms by adsorption on a crystalline, zeolitic molecular sieve at 120-455  DEG C. followed by desorption of the normal paraffins without any introduction of external heat by reducing the total pressure in such a manner that the desorbed hydrocarbons flow in a direction countercurrent to the feed stream flow.  The feed may boil in the range -25-150  DEG C. and is treated at a pressure of 150 mm. Hg to 5 atmospheres.  The sieve may be a calcium zeolite A, strontium zeolite A, magnesium zeolite A, zeolite D, calcium zeolite D, zinc zeolite D, zeolite T, calcium rich chabazite or erionite rich in sodium, calcium, magnesium or zinc, and should have a pore size of about 5  . Desorption may be effected by reducing the pressure to 10-250 mm. Hg.  In treating C6+ streams the presence of n-pentane or n-butane in the feed prevents breakthrough of n-hexane and similarly with n-butane in C5+ streams.  Sieves may be periodically regenerated by oxidation at 400-565  DEG C. as described in Specification 954,852.  Specifications 777,232, 868,846 and 912,936 also are referred to.

Tilting or inverting vessel apparatus. - A container 1 for liquid fuels, lubricating oils &c. is divided into two chambers by a partition 2 communicating only by a tube 10, a spout 6 leading from the lower chamber at a point opposite to the tube 10 and terminating in a nozzle 7 and cap 8. A vent tube 12 leads from the tube 10 out through the wall of the spout. The lower compartment fills from the upper compartment through an aperture 9, the displaced air escaping through a tube 11. The container can only be filled to the end of a tube 5 which can be closed by a cap 13. When the container is tilted for pouring, the liquid in the vent tube 12 having to leave that tube before vent air can enter, allows time for the tilting without wasting liquid ; further, the aperture 9 being above the surface of the liquid when the container is in the tilted position, only the liquid from the lower chamber can be emptied at one tilting, the apparatus thus serving for delivering measured quantities. To stop the flow before the lower chamber is emptied, the spout is immersed in liquid so as to cover the exit of the vent tube 12.
