Title: Preparing cold-rolled steel strip
IPC: C21D1/70
Filed: 1964-12-01
Abstract: A strip of steel, cold-rolled in the full-hard state (Rockwell hardness at least 80), is prepared by treating it with a phosphating solution, collecting the phosphated strip as a coil, annealing the coil of phosphated strip in a non-oxidizing atmosphere at 900-2400 DEG F, uncoiling the annealed coiled strip while under tension e.g. by drawing it off from the coil held in an expansible mandrel around a working roll, and then temper-rolling the strip.  The temper-rolled strip may be cut to length and lubricated with a borax-soap mixture for cold-forming e.g. into bumpers and subsequent finishing, particularly chromium plating.  The cold-rolled strip is preferably cleaned by an alkaline detergent spray prior to phosphating e.g. in a solution containing 1.5 to 8% Zn ion, 3.5 to 20% PO4 ion, 5 to 26% NO3 ion, 1 to 4.5% Ca ion, and optionally 0.4 to 2% NH4 ion and/or 0.5 to 3.5% Cl ion; supplementary ions such as bromide, (per) chlorate, nitrite or perborate ions may also be present.  The phosphate coating e.g. exhibiting scholzite crystal structure is preferably sealed by a chromic acid or borax rinse.

Abstract: 1521757 Underwater breathing apparatus WESTINGHOUSE ELECTRIC CORP 11 Dec 1975 [11 Dec 1974 (2)] 50810/75 Heading A5T [Also in Division F2] In a push-pull system for supplying air to a diver headgear, there is, in series, in the outlet line 43, 45, 47 a normally open failsafe valve 108 and an exhaust control valve 109, each valve having inlet and outlet chambers 110, 111, and a third chamber 116 forming a pressure sensing chamber out of the flow path and in direct communication with the interior of the head gear. In the failsafe valve, Fig. 8B, the pressure in chamber 116 acts with a spring 123 on an actuator 114 and diaphragm 125 which is acted upon from the other side by ambient water pressure. The weight of the actuator 114 also influences valve operation in dependence upon the valve's  orientation. The exhaust valve is identical with the failsafe valve except that the spring 123 acts on the other side of the actuator 114. Should the exhaust valve fail in an open position the pressure in the headgear will fall and the failsafe valve will close. The pressure will then rise to a level permitted by a vent valve 51. Should the failure of the exhaust valve by rectified the failsafe valve will automatically reopen. In a modification, Figs. 12A, 12B (not shown) the failsafe valve requires resetting after closure. Air is supplied from a remote source 12 by a pump 14 and withdrawn by a pump 20.

The reduction is effected conventionally with H2, coke, coal or CO. The carbonylation may be effected at 100- 200‹ C. and 1-200 atm. pressure. The product is Fe(CO)5 which is decomposed to iron and CO at 280-350‹ C., the CO being recycled. The ilmenite may initially be heated in air at 500- 1000‹ C. to convert Fe<2+> to Fe<3+>. Comparative examples use NH3 or S as catalyst for the carbonylation.

Abstract: 1,255,828. Rolling mills. HITACHI Ltd. 29 Oct., 1969 [30 Oct., 1968], No. 53069/69. Heading B3M. A rolling mill is provided with spacers for maintaining the work rolls of the mill in a spaced condition during a roll changing operation. The spacers are permanently incorporated in the mill and are automatically brought into operation during roll changing. Rods 40 extend vertically through the chocks 34 of a lower roll, the rods normally being supported as shown in Fig. 7 by upper flanges 43. When the two rolls are to be moved from the mill, the lower chocks are dropped until rollers 45 on the rods contact fixed rails 39 within the mill windows and the chocks rest on surfaces 42 of the rods, Fig. 8. The upper roll is then spaced from the lower one, and the two roll assemblies can be removed from the mill on the rails. The work rolls of a four-high mill can be changed in a similar manner but the rails in this case are vertically movable and are located adjacent the lower work roll chocks. In an alternative form of the rods, the rollers can be separate from the rods and provided on a trolley.

Monogrammic display means comprises for each colour to be displayed: a plurality of light sensitive means (e.g. photo-resistors 4(1), 4(2) ..., Fig. 1); an equal number of lamp bulbs 14 of that colour; a pair of switching devices 12 connected in back-to-back relationship in series with each lamp bulb and a source (a) of alternating voltage, Fig. 2; pulse generating means 11 to switch on in alternating sequence the switching means 12 of each pair; and means for controlling the brilliance of each lamp 14 in proportion to the light energy falling on its corresponding light sensitive means, by determining at what point in each half-cycle of the A.C. source (a) the switching means 12 is activated by the pulse generator 11. As described, the device is controlled either by projectors (18) one for each colour, each of which shines a light image on to a screen (17) covered with an array of light sensitive means corresponding in spatial configuration to the display lamps, Fig. 4 (not shown); or by a single projector (18), the screen (17) being covered by an array of groups of light sensitive means (4) each member of the group having a different colour filter in front of it, Fig. 5 (not shown). Fig. 1 illustrates a first control circuit. A plurality of bridge arms are connected across the A.C. source (a). Point e on the first bridge presents a reference voltage; its level may be determined by varying resistor 2, e.g. resistor 2 may be sensitive to the ambient light. The voltages at points f, g, h ... on the other bridges are determined by the intensity of light falling on photoresistors 4(1), 4(2), 4(3) . . . The devices 10 are measuring amplifiers; according to the " error voltage " received, e.g. the difference between voltages e and f, so the time taken to charge up a capacitor (not shown) varies and so the exact instant of pulse generation by the device 11 varies, hence controlling the brightness of lamp 14. In a second control circuit, Fig. 3, the device 13 is a D.C. generator having a light-sensitive component, e.g. a photo-diode or -transistor. Reference has been directed by the Comptroller to Specification 1,052,372.

Title: Apparatus for calculating the standard deviation of a property of articles

Filed: 1971-11-17
Abstract: 1406218 Measuring standard deviation MOLINS Ltd 16 Nov 1972 [17 Nov 1971] 53337/71 Heading H3H Apparatus for measuring the standard deviation of, for example, the mass of tobacco in cigarettes comprises a comparator 2, a divider 4 which produces a succession of pulses in synchronism with the cigarette lengths fed past a measuring device, a digital counter 5 and a digital to analogue converter 6. The mass of tobacco in successive portions of a moving cigarette rod is determined by an ionization chamber which measures the attenuation of #-rays by the rod to supply a mass dependent signal to an input terminal 1. The comparator includes an integrator which integrates the difference between a desired reference mass signal and the actual mass signal for successive portions of the cigarette rod. A threshold device (24), Fig. 3 (not shown), supplies a pulse to increase the count in the counter 5 whenever the actual mass is less than the reference mass whereas the count is decreased by unity by the divider 4 which produces one pulse for sixteen cigarette length portions of the rod. It can be shown that, for a Gaussian distribution, if the difference between the mean value and the reference value is 1À53 times the standard deviation then one sixteenth of the cigarettes have a mass below the reference value. Hence when the circuit 2, 5, 6 is stabilized the reference output voltage from the converter 6 is proportional to the standard deviation plus the difference between the actual and desired mean mass. A similar circuit which allows for variation of the mean mass includes a comparator/integrator 12, a relay 13, an up/down counter 15 and a digital to analogue converter 16. When this circuit is stabilized, the reference output voltage from the converter 16 is proportional to the difference between the actual and desired mean mass. By subtracting the two reference voltages a signal proportional to the standard deviation of the tobacco mass in a cigarette is obtained and may be used for monitoring a cigarette making machine.
