Title: Improvements in processes of and apparatus for obtaining volatilizable metal oxides
IPC: C01B13/32
Filed: 1920-07-08
Abstract: 147,470. Robertson, F. D. S. Dec. 16, 1918, [Convention date]. Molybdenum, vanadium, arsenic, and other volatile oxides.-A volatile oxide is obtained by treating material capable of yielding it with a current of heated gas and subsequently cooling the gas to extract the oxide, the remaining gas being preferably heated and returned to take up more oxide from the initial material. The invention is described with particular reference to the production of molybdic acid from molybdenite. Molybdenite is fed through a hopper 10 into a rotary furnace 11 heated by a fire-box 13. Heated air is admitted from openings 15 in a pipe 14 within the furaace. The furnace may be provided with ribs 16 to pick up and shower down the material. The gas stream carrying the oxide passes through a chamber 17 in which it is partly cooled, and thence by a pipe 18 to a tower 19 and bag-house 20. The gas issuing from the bag-house through a pipe 21 is passed by a fan 22 through a pipe 23 and coil 25 back to the pipe 14. In order to maintain the oxidizing character of the gas stream, air is admitted by a pipe 26 on the suction side of a fan 24, and a corresponding quantity of gas is withdrawn at 27 and discharged. The cooling of the gas and the addition of oxygen may be effected simultaneously by admitting a quantity of liquid oxygen or liquid air. The process may be effected under pressure or reduced pressure, but the step of volatilizing the oxide is preferably effected under reduced pressure.

Title: A warning signal for use with ships telegraphs
IPC: B63H21/22
Filed: 1922-07-18
Abstract: 197,238. Mair, T. W. July 18, 1922. Signalling disagreement of controlling gear and the like with order telegraphs. - A mechanical alarm-bell is rung when the controlling gear of a ship's engine is in disagreement with the bridge telegraph while the engine is running. A plate C is arranged over a plate B on a base plate A, the plates B and C being adapted to slide independently to right or left, Fig. 1, guided by slots in the plate A. These sliding motions are respectively derived from enclosed cams F and F<1> which are turned by the wheels O, O<1>, geared respectively to the order telegraph and to some part of the engine controlling gear, such as the weigh shaft, valve motion, or reversing gear. When the plates B and U move together, no signal is given, but when an order is wrongly executed, the plates move relatively to one another, and one of the projections H, H', Fig. 1, belonging to striking mechanisms carried by the plate B, comes into the path of projections U, U, or U<1>, U<1> on a centre piece L, which is carried by the plate C and is reciprocated by the running engine through a spindle K. The projections H, H<1> when struck by the projections U or U<1>, operate spring-controlled hammers G, G<1>, one of which continues to the bell J carried by the plate C so long as the disagreement persists.

Title: Improvements in or relating to the production of starch pastes
Inventor: SCHINK NORBERT FREDERIC
IPC: C12P19/14
Filed: 1963-05-21
Abstract: <PICT:0991778/C3/1> <PICT:0991778/C3/2> <PICT:0991778/C3/3> <PICT:0991778/C3/4> Starch paste is made by injecting an aqueous slurry of starch incorporating an amylase preparation with steam at such a pressure that the starch is gelatinized substantially instantaneously without deactivating the enzyme.  After steam injection, the gelatinized starch and amylase may be passed through a conversion zone to effect enzymic hydrolysis, and the resulting starch paste passed through an enzyme deactivating zone, wherein the temperature of the paste is raised by further injection of steam. The process may be continuous.  In one embodiment (Fig. 1), corn starch, water, calcium carbonate and amylase 0.01-0.07% by weight on dry starch basis is mixed in tank 11 to form a slurry with starch solid content of 10-38% dry substance.  The slurry is transferred by pump 12 to direct steam injection heater 14, and after gelatinization at 195-200 DEG  F., is discharged on to perforated baffle 16 in heated conversion tank 15, where enzymic hydrolysis takes place.  The paste moves slowly down tank 15 and is discharged to a second steam injection heater 24 and holding pipe 25 whereby the temperature is raised to 240-280 DEG  F. for, e.g., 10 seconds to deactivate the amylase.  The paste may be diluted with water from 26 or steam may be flashed off in chamber 28.  In one form of heater (Fig. 2) steam enters passage 32 in bronze block 31, travels along ports 34 and impinges tangentially on a stream of starch slurry or paste entering at 36 and flowing round solid rod 36a to exit at 33. In a second form of heater (Fig. 4) steam, entering at 143, travels along inner pipe 125 and flows through cut-out area 135 therein, and thence through orifices 128 in an injector pipe 114, to impinge on a stream of starch slurry or paste flowing inside casing 110.  The starch is fed in at inlet 138, which is tangential to the cylindrical casing 110. The inner pipe 125 may be turned relative to the injector pipe 114 so that the cut-out area 135 may register with a varying number of holes thereby permitting a variable flow of steam into space 115 containing the starch slurry or paste.  The pipe 125 may be positioned so that all the orifices 128 are covered, thus cutting off supply of steam to the starch. Gelatinized starch exits through 142.  The starch traverses a helical path in space 115.

Abstract: 1501242 Battery plate paster GATES RUBBER CO 21 April 1975 [23 April 1974] 20221/77 Divided out of 1501241 Heading D1L A battery pasting apparatus for pasting lead-acid battery plates in a continuous manner by application of a thixotropic lead paste on to a foraminous lead substrate which is moved substantially horizontally comprises. a supply of the lead substrate, a supply of the lead paste, a nozzle adapted to be positioned above the substrate for discharging the paste at a predetermined rate of flow on to the substrate without substantially deforming the substrate, a set of opposed driven rolls spaced from the nozzle to receive within its nip the pasted substrate and to compress the paste within the interstices of the substrate and a cutter for severing individual plates from the continuous length of pasted substrate. In the apparatus shown the substrate 16 is supplied from the spool 18 and delivered beneath the nozzle 10. The nozzle 10 does not bear with any appreciable downward force upon the moving grid 16 and may be able to pivot freely about its inlet position 12. A thin ribbon of paste 20 deposited upon the grid is of sufficient viscosity to prevent appreciable permeation downwardly through the interstices of the grid. As the thus pasted grid 20 is moved to the left it encounters the nip 22 of juxtaposed pasting rolls 24, 26. The two rolls are preferably driven at essentially the same speed although they may be driven at different individual speeds. The rolls may be of steel and may be prevented from adhering to the grid by interposed layers of a thick flexible, stick-resistant material 28 and 30. This may be of paper. This material may be omitted if the rolls are rendered sufficiently non-adherent. The substrate is then passed to a plate slitter 40 and plate cutter 38 for fabrication of the final electrode structures 42.
