Title: Vibratory machine
IPC: F26B17/26
Filed: 1974-02-11
Abstract: 1449966 Vibratory mills; coating apparatus OXY METAL FINISHING CORP 11 Feb 1974 [9 Feb 1973] 06161/74 Headings B2A and B2L [Also in Divisions B3 and F4] A vibratory treating and drying machine comprises a processing tank I connected to a vibration generator 6, and a radiant heater 13 stationarily mounted below the tank and facing a wall of the tank, heat supplied to the wall being transmitted to the contents of the tank by conduction. The treatment may consist of the crushing of granulates or pulverulent material, or finishing, polishing, grinding, trimming, burnishing, painting, coating or other surface treatment of parts. During drying, usually following the treating, a drying agent such as sawdust or vegetable granulate is poured into the tank. The tank may be annular and either circular or polygonal and is mounted by springs 5 on a frame 3. The base 2 of the tank carries a vibration generator consisting of a motor 6 and weights 7, 8. As described, three infra-red radiant heaters 13 are fixed below the base of the tank to effect drying of the contents. A skirt 14 extends downwardly from the tank to ensure absorption of the radiation. The heaters may be arranged along the inner and/or outer vertical walls of the tank. In another embodiment, the tank is in the form of a straight semi-cylindrical trough and several infra-red heaters are arranged transversely or longitudinally beneath the tank. A screen (15, Fig. 1, not shown) may be provided for effecting sorting, screening or separation.

Title: Process of refining zinc oxides
IPC: C09C1/04
Filed: 1944-04-03
Abstract: <PICT:0581840/III/1> Zinc oxide is refined by heating at 650-950 DEG C. for, e.g., 15-30 minutes in a clean reducing atmosphere free of soot or solid carbon.  The gases preferably move in countercurrent at not less than 50ft. per minute and may be diluted with steam or inert gas. The colour may be improved by an oxidising treatment at the same temperatures or by alternating the two treatments at regular, preferably 5 minute, intervals.  The residual sulphur is present as sulphide or sulphate according as the oxide is cooled in a non-oxidising or oxidising atmosphere.  Cadmium is recovered as metal, oxide, or sulphate.  Sulphur, arsenic, antimony and lead are removed.  As shown the oxide is charged by a conveyer 6 into a brick lined rotary kiln 1, and discharged after about 15-30 minutes treatment by a water cooled conveyer 10 which may be supplied with inert gas at 32, to an air sealed receptacle 12. Butane, water, producer, or natural gas supplied at 17 and 18 is mixed with air from a blower 19 in mixers 20 and 21 to supply the burner 14.  Gas mixtures having 40 per cent. excess or 30 per cent. deficiency of air are produced according to which of valves 22 and 23, alternately opened and closed by a time controlled switch operated solenoid 24, is open.  The temperature of the combustion chamber 14a is reduced from 1,500 DEG C. and the gas volume and velocity increased, preferably to 50-200ft. per minute, by steam or inert gas fed at 31. The ejector fan 8, bye-passed by a stack 9, draws the exit gases through a collector 7 where dust and cadmium compounds deposit. Direct fired or muffle type furnaces and two furnaces operated in tandem may be used.

Title: Improvements in or relating to automatic cop changing devices for looms having a drum-shaped cop magazine
IPC: D03D45/20
Filed: 1952-03-11
Abstract: 719,649. Automatic weft-replenishing looms. FISCHER AKT.-GES., G. March 11, 1952 [March 12, 1951], No. 6325/52. Class 142(2) A disc on the end of a drum-type cop magazine has groves engaged by a locking lever which is moved by a second lever through a resilient linkage from a weft stop motion. When a rod 7, Fig. 5, is moved by the weft stop-motion, it turns a shaft 5 through a spring-load clutch and a roller 14 on an arm 15 moves along a curved edge 12' on a locking lever 12 pivoted at11 and moves a pin 16 to engage a groove 4<SP>1</SP> on a disc 4 on the magazine. Movement of the lever 12 causes a rod 17 to remove a spring-loaded shuttle top plate. When the shaft is turned, a lever 26, Fig. 1, on the shaft also turns and a roller 24 swings clear of a cam 21<SP>1</SP> and a spring-loaded finger 21 lifts in readiness for engagement with a member 23 on the slay 22 to operate the transfer hammer 19. A shuttle protector moves the finger down again if weft replenishment is to be revoked. A roller 27, Fig. 3, on a spring- loaded ratchet lever 28 engages the weft hammer, and when the hammer swings down, it swings the lever 28 and a spring- loaded pawl 31 thereon moves out of a groove 4<SP>1</SP>. When the hammer swings up and the pin 16 moves clear of one of the grooves 4<SP>1</SP>, the pawl 31 turns the disc 4 until a new cop A touches a stop 34. The grooves 4<SP>1</SP> may or may not be the usual grooves that engage the ends of the cops.

Title: Improvements in or relating to fabric take-up motions of weaving looms
IPC: D03D49/20
Filed: 1923-03-05
Abstract: 194,319. Oehlschlõgel, G., and Eilhauer, F. March 4, 1922, [Convention date]. Take-up motions.- In regulators of the type wherein the fabric is tensioned by means of a weight c', the actuating lever h connected to the pitman i of the " lifting device " actuates the fabric roller shaft a through a pawl k engaging a ratchet wheel g fixed to a bevel wheel f geared to a bevel wheel e, which is geared to a bevel wheel b fixed to the shaft a. Back motion of the ratchet wheel g is prevented by a pawl n and the pivot d of the wheel e is carried by a lever c loosely mounted on the shaft a and carrying the fabric-tensioning weight c<1>. An obturating member m is rigidly connected by a bar l to the lever c so as to cover the teeth of the ratchet wheel g to a varying extent and thus vary the amount of rotation of this wheel and consequently the take-up according to the position of the lever c. In a modification, the effective length of the actuating-lever is varied, by means of a rod connected to the weighted lever and to an extension of the pitman, so as to displace a pin carried by the pitman in a slot in the actuating lever.

Filed: 1963-02-21
Abstract: 997,058. Electromedical apparatus. DYNAPOWER SYSTEMS CORPORATION. Feb. 21, 1963 [July 2, 1962], No. 7001/63. Heading A5R. Electrotherapeutic apparatus comprises a radiating treatment head and a circuit for applying high-frequency pulses to the head including an oscillator, an amplifier, a vibrator to interrupt the amplified signal at predetermined intervals determined by a first step switch, a power amplifier transmitting the pulses to the treatment head and second step switch means connected to the power amplifier to control the amplitude of the pulses. High frequency oscillations generated and doubled by an oscillator 14 which includes a crystal 24 are transmitted to a frequency doubling amplifier 16, a power amplifier 17 and a pi network 19 to a treatment head comprising a tank circuit which includes a variable capacitor 13 and a secondary coil 10. Transmission of oscillations by the amplifier 16 is intermittently interrupted by a switching input provided by a multivibrator 33 connected at 30 to the amplifier, the pulse interval being controlled by a step resistance selector 45 in the grid input of the multivibrator. The amplitude of the output pulses is adjusted by a second step resistance selector 72 connected at 67 to a pulse amplitude control 60 which is connected at 63 to screen grids 86 of the valves 56 of the power amplifier. The second step resistance selector 72 is arranged in series with an auxiliary step resistance selector 76 which is mechanically connected to be operated simultaneously with the step resistance selector 45 controlling the pulse intervals so that an adjustment to vary the pulse interval does not result in an undesirable change in pulse amplitude. A feedback coupling 64 from a point 87 between the pi network and the radiating head to the grid 65 and plate 66 of one tube 61b of the pulse amplitude control 60 causes a drop in voltage applied to the grids of the power amplifier valves, to compensate for any undesirable increase in output amplitude. The reading on a meter 96 connected between the first and second step resistance selectors varies in response to operation of either or both selectors.
