Title: Improvements in or relating to growth methods for single crystals of zinc oxide
IPC: H01L41/39
Filed: 1961-01-16
Abstract: Hexagonal plate-like zinc oxide crystals are grown by dissolving zinc oxide in a solvent consisting substantially wholly of lead fluoride by heating to a temperature within the range 1030 DEG  to 1300 DEG C., the amount of zinc oxide introduced being sufficient to produce saturation of the lead fluoride at a temperature within said range, and cooling the resultant solution to cause growth of the crystals, cooling of the solution within the range 1300 DEG  to 1030 DEG  C. being at a maximum rate of 5 degrees per hour. Baths containing 1% or greater of impurities such as iron, cobalt, nickel, manganese, copper or lithium, do not affect the crystal habit, but antimony, bismuth and arsenic should be avoided. The amounts of zinc oxide and lead fluoride to be used are dependent upon the desired temperature of initial nucleation; from the graph the maximum amounts of zinc oxide tolerable for given maximum temperatures can <PICT:0959294/C1/1> be obtained.  The preferred flux composition corresponds with saturation over the range 1030 DEG  to 1300 DEG  C. (from 21 to 48 mol. per cent zinc oxide based on the entire bath).  The initial ingredients, i.e. ZnO and PbF2, are placed in a crucible which is then covered and heated in a furnace to the desired temperature in the range 1030 DEG to 1300 DEG  C., a partially sealed system being used.  The contents are allowed to cool at a maximum rate of 5 DEG  C. per hour until a temperature of 1030 DEG  C. is reached when the entire flux is quenched by removing the crucible from the furnace and allowing the contents to cool to room temperature. Alternatively, on termination of crystallization at 1030 DEG  C., the liquid flux may be removed by pouring.  Specification 959,293 is referred to.

Abstract: 292,872. Fairweather, W., (Singer Manufacturing Co.). Jan. 21, 1928. Multiple-needle machines; chain-stitching.-A chain-stitching machine of a similar kind to that described in Specification 270,174 has a loop holder and a looper for each needle, operating in substantially coincident planes at the same side of the needle path parallel to the line of feed, such loop-holder and looper having simple oscillatorv movements. The invention is illustrated as applied to a three needle machine. At the moment the needles 10 begin their upward stroke, loop holders 13 are timed to advance their points 14 into the needle loops. As the needles continue the upward stroke, the points 14 engage the needle loops and hold them without spreading while the loopers 17 advance into position for entering the loops, Fig. 6. At the limit of the upward stroke of the needle, both loop holder and looper are engaged in the loop. As the needle descends again, the loop-holders retire from the loops and the loopers 17 present the loops for entry by the needle, on its down stroke, Fig. 8. The cycle is repeated as the needle re-ascends. The loopholders 13 are mounted on a shaft 11 and are driven by a crank 23, pitman 21 and eccentric 19 on the main shaft 6. The loopers are mounted on a pin 16 secured by a strap 15 in parallel rotation to a hollow shaft 12, coaxial with the shaft 11 and driven by a crank 24 and pitman 22 from the eccentric 20 on the main shaft. The needle holes 42 have shelves 43 with inclined edges 44 to assist the looper thread to bow away from the blade of the looper and open for the needle. Governing needle-thread. - The needle threads are governed by a rotary take-up and a thread nipper. The take-up comprises spaced parallel discs 7 between which is located a fixed plate 45, Fig. 3, having a thread slot 46. A bent wire guide 47 positions the thread for the action of the discs. The thread-nipper comprises a seat 48, yieldingly mounted in a recess 50 in the arm 4, and a head 49. As the shaft 6 rotates, an eccentric 56 actuates a follower 55 and yoke 54 to reciprocate the rod 53 to release and nip the thread between the parts 48, 49. A multiple threadtensioning device is provided comprising the spring-pressed tension discs 57 mounted on the plate 58 which is held spaced from and fixed relatively to the supporting plate 59 by corner posts 60, the plate 59 being coaxial by a bracket 61 on the gooseneck 4.

Title: Improvements in method of reclaiming lubricating oil and devices therefor
IPC: F16N39/06
Filed: 1922-01-24
Abstract: 198,002. Gross, E. L. Jan. 24, 1922. Recovering waste lubricants.-In the continuous purification of the lubricating oil of internal-combustion engines by heating, filtering, and submission to reduced pressure, the vacuum is repeatedly made and broken, the oil is positively cooled before being returned to the crank case, and the discharge of the oil from the purifier is controlled by two automatically operated check valves. In the apparatus illustrated suction in a pipe 76 draws the oil from the crank case through a pipe 75, heater 71, and filter 30 to a purifier 1; the oil is periodically discharged through a cooler 63. The pipe 76 is connected to a pump, a cylinder, or to the intake manifold, preferably through a non-return valve 80 so that fluctuations of pressure in the manifold are not transmitted beyond the valve; the impurities vaporized from the oil pass to and are consumed in the engine cylinders. As the oil fills the purifier 1 a float 18 rises, and through an arm 12 on a pivot 13, a link 11, and arms 10, 8 on a pin 9 and connected by a spring 17, lifts valves 7, 6 to cut off the pipe 76 and open the purifier to the atmosphere. The vacuum being broken the check valves 54, 54<1> fall and the oil flows through the cooler 63 and pipe 62 to the crank case. When the float 18 has fallen sufficiently the arms 8, 10 are snapped back and the valves 6, 7 depressed, cutting off the air and opening the suction pipe so that the purifier fills and the process is repeated. The cooler 63 comprises compartments 57, 60 connected by tubes 58 having cooling fins 59. It is placed behind the radiator fan. The heater 71 comprises a bore 82 which is screwed into exhaust manifold 72, and which is fitted with an inlet tube 73 having a spiral groove 74, an outlet 76, and a shell or thimble 79. The filter comprises a vessel 30 provided with a closely fitting plate 43 which supports a perforated tube 39, surrounded by a strainer 40, and a central tube 38 that is formed with a series of inlet tubes 42 at its lower end and is threaded into the opening 37 formed in the removable cover 31. Radial passages 33 connect the opening 37 with a circular passage 34 connected by a hole 36 to the purifier 1. Some sediment may be run off through cock 50. All is removed by withdrawing the cover 31 and the attached plate 43 and strainer 39, 40. In a modified apparatus the filter 30 and purifier 1 are combined. The heater 71 may be replaced by a coiled tube having its inlet and its outlet in a plug adapted to be screwed into the exhaust or other heated part of the engine; or it may comprise a jacket on the exhaust pipe.
