Title: Improvements in or relating to processes for the protection of metals against corrosion at high temperature
Inventor: SCHEIN FRANCIS
IPC: C23F13/02
Filed: 1962-05-25
Abstract: Metals and alloys at high temperatures are protected against corrosion by gases if the metal to be protected constitutes the negative electrode and is superficially coated with a solid corrosion product formed on the metal with the solid positive electrode in contact with the outer surface of said corrosion product; and the conductivity of the solid electrode exceeds that of the corrosion product.  The corrosion product, stable at high temperatures, is an oxide, a sulphide or an inorganic salt of the protected metal and the positive electrode is formed by a metal, e.g. Pt, which is infusible and non-corrodible at the high temperature of operation. Alternatively the positive electrode can be an oxide or other compound infusible at the high temperature of operation, inert to the corrosive gases and of higher conductivity than the corrosion product. The current density is at least egual to 0.01 mA/cm.2 and for certain metals or alloys, e.g. stainless steels, the current may be wholly interrupted for protracted periods without observing resumption of corrosion. The positive electrode may take the form of a grid, a wound spiral or metal plated over the corrosion product. The invention caters for temperatures exceeding 500  DEG C. and more, generally exceeding 800  DEG C.  Gases mentioned are O2, air, CO2, water vapour, SO2, H2S, and combustion gases in general; but vapours formed by the decomposition and vaporization of solids or liquids, such as nitrates, chlorates, perchlorates, hydrogen peroxide, may also be corrosive.  The invention may be applied to Fe, Ni, Co, Cr, Mo, W, V, Zr, Ti, Ta, Al, Mg, Cu, and Zn, and their alloys.

Abstract: 1,075,036. Electric selective signalling. DEMAG-ZUG G.m.b.H. May 13, 1965 [July 24, 1964], No. 20328/65. Addition to 1,074,336. Heading G4H. In a digital control device, a counter with five two-state stages supplies actual value signals to AND gates which also receive desired value signals via diodes, the outputs of half the AND gates being connected to a " forward " output and half to a " reverse " output, the "reverse" AND gates being closed to all actual value 1-states corresponding to a numerical value less than or equal to the desired value and the " forward " AND gates being closed to all desired value 1-states corresponding to a numerical value less than or equal to the actual value. A feedback positioning system incorporates the above arrangement for one decimal order, similar arrangements being provided for the other orders. The direction of the positioning motor is controlled by the " forward " and " reverse " outputs of the highest decimal order in which the desired and actual value digits are unequal, by means of inverters and OR gates (e.g. Fig. 2, not shown). Triggers (T1, T2, T3, Figs. 1A, 1B, not shown) respond to the number of AND gates producing a 1- output, and, together with " forward " and " reverse " signals, control logic circuitry (e.g. Fig. 3, not shown) to allow the positioning motor as the end-point is approached.

Title: Improvements in or relating to means for regulating and synchronizing electric motors and the like
IPC: H04N1/36
Filed: 1926-08-18
Abstract: 257,272. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Ranger, R. H.). Aug. 19, 1925, [Convention date]. Copying and writing telegraphs.-To maintain constant speed of electric motors or the like for transmitting or receiving facsimile messages by wireless telegraphy, the motor 2 is automatically and periodically corrected by impulses from two separate constant-frequency vibrators, one giving coarse adjustment and the other fine adjustment. In the arrangement shown the coarse adjustment vibrator is an electrically maintained tuning- fork 4 in series with a rotary brush switch 20 driven by the motor and having its alternate segments connected to the motor armature and field so that a normal balance between speeding- up impulses and slowing-down impulses is disturbed when the motor speed varies from the fork speed. The fine adjustment vibrator is a clock pendulum 29 in circuit with a motor-driven contact-breaker 32 arranged to start or stop an auxiliary motor 39 whenever the contactbreaker falls out of synchronism with the pendulum, the auxiliary motor acting through a worm drive 44 to superpose a slow movement on the normal rotation of the rotary switch 20. Similar arrangements including vibrators of the same frequency may be used at the transmitting and receiving ends independently, thus replacing systems in which one motor sends out synchronizing impulses to the other motor over the path of transmission. A neon lamp 45 mounted eccentrically on the motor shaft may be used to indicate constancy of speed and departures therefrom.

Filed: 1971-04-19
Abstract: 1285165 Sealing film cassettes AGFA. GEVAERT AG 19 April 1971 [21 Feb 1970] 20432/71 Heading B8C A loaded film cassette of plastics material is sealed by spraying the cassette body and U- shaped cover at the joins with a predetermined amount of solvent. As shown in Fig. 3, the lowest of a stack of cassettes 10 in a magazine 15 is thrust by a piston 16 into a receiver 19 on a stepwise rotatable disc 18 from which it is thrust into a spraying station 21 by a piston 22. As shown in Fig. 5, the spraying station 21 comprises a receiver 24 supplied with solvent through a plurality of plug connectors 37, small bore tubes 35 and bores in discs 32, 34 and a packing 33 from piston and cylinder devices 27, 28, 29. The piston-rods 27 are held on a disc 26 which is movable vertically by means of a piston 40 acting through a lever 41, pawl (42), and ratchet-wheel (43). The quantity of solvent dispensed can be adjusted by adjusting the position of the pivot point 44 by which the piston 40 and lever 41 are connected. The cylinders 29 are refilled by means of the packing 33 which in one angular position allows solvent to pass from the cylinders 29 to the tubes 35, and in a second angular position allows solvent to flow from a reservoir into the cylinders 29. The solvent on the cassette dries, or further treatment may be carried out, as the cassette travels around the angle α in the disc 18 before being ejected by a piston 57. The operation of disc 18 is controlled by feeler devices 20 and 25 in receivers 19 and 24 respectively. In a modification (Fig. 8, not shown), one double measuring cylinder (52) replaces the plurality of piston and cylinder devices 27, 28, 29, the cylinder being supplied with solvent from a reservoir (50) under constant pressure and being discharged into a connection piece (56) through offset bores (55) when both bores are freed by the double piston (53). The quantity of solvent sprayed can be adjusted by varying the speed of the piston (53) or the liquid pressure.

Title: Improvements in or relating to the purification of substantially anhydrous normally liquid distillable halides of metals of group iv of the periodic table
IPC: C01G1/06
Filed: 1943-12-08
Abstract: A substantially anhydrous stable distillable halide of a metal of Group IV of the Periodic Table, e.g. titanium tetrachloride containing vanadium as impurity, is purified by contact with elemental sulphur with or without the application of heat.  The sulphur may be dissolved or dispersed in the halide and the mixture allowed to stand.  The rate of reaction may be increased by heating the mixture under reflux, the impurities being separated by subsequent distillation.  The effectiveness of the purification is enhanced by the presence of a free halogen in the halide, or by the addition of sulphur halides or heavy metal soaps such as the stearates, laurates, oleates, linoleates, palmitates, &c. of iron, nickel and cobalt.  In a modification, purification may be effected in vapour phase using sulphur halides.  Metal halides specified are the tetrachlorides of titanium, tin and germanium and the tetrafluoride and tetrabromide of titanium.  The Specification as open to inspection under Sect. 91 comprises also the purification of arsenic chloride and the liquid bromides, fluorides and iodides of silicon, tin and germanium.  This subject-matter does not appear in the Specification as accepted.
