Abstract: 1281022 Enamelling metals G. SCHAUMBURG 25 June 1969 [25 June 1968] 31985/69 Heading C1M A rolled metal product, particularly of steel, is coated with an enamel, as it emerges from a stand of a rolling mill sufficiently hot to fuse the enamel, and, with or after the enamel, a corrosion-resisting medium. The enamel may contain SiO 2 , Al 2 O 3 , CaO, MgO, Na 2 O, K 2 O and B 2 O 3 , and may be applied as the enamel frit or as a mixture of the oxides. The corrosion-resisting medium is preferably zinc borate, which produces a zinc layer. The enamel may be removed from the metal before applying the corrosion-resisting medium, in which case a conventional coating of lacquer or plastics material may then be applied. The enamel is said to preserve the descaled state of the rolled metal. A reducing agent, e.g. a reducing gas or finely-divided metal, may be applied before or with the enamel. In the embodiment shown, rolled metal 3 emerges from a stand 1 of a rolling mill and is enamelled in chamber 4, wherein powdered enamel is blown as a dispersion on to the metal, the enamel being removed subsequently after cooling, by rollers 6, after which the corrosion-resisting medium is applied by sprayers 7. Specifications 1,277,755 and 1,281,021 are referred to.

Abstract: 1,175,872. Control of D.C. motors. WESTINGHOUSE ELECTRIC CORP. 17 July, 1967 [3 Aug., 1966], No. 32674/67. Heading H2J.  When work rolls 12 of a mill are to be replaced, the mill is shut down and motor 19 is operated to place spindles 16, 18, in a predetermined angular position. A selector circuit 36 sends a signal to circuit 40 whereby the motor is operated at a creep speed until slug 48 initiates operation of switch 44. A feedback signal is accordingly sent to selector circuit 36 for operation of pulse generator circuit 38 after the drive train has rotated sufficiently to enable friction to be reduced by lubrication. The motor is then moved in steps until slug 48 reaches stop switch 46, whereupon the pulse generator is turned off. Braking resistors 58, 60, are connected into the armature circuit during the positioning operation. The motor has a double armature 20, 22, and, during normal mill operation, the armature supply circuit 32 is controlled by signals representing the speed, armature voltage, and armature current of the motor, these signals being cascaded to determine the thyristor firing angle in the circuit 32. Supply circuit 30 provides maximum field up to base speed, and then reduced flux at constant back E.M.F. A speed reference voltage on line 35 is varied to provide acceleration, steady running, and deceleration operations of the mill motor. A digital computer may be programmed to determine the speed reference.

Abstract: 1279511 Measuring altitude rate BENDIX CORP 8 July 1970 [16 Sept 1969] 33123/70 Headings G4A and G4H A function generator includes a counter 11a (Fig. 7) pulsed at a frequency dependent on its count. As described for computing altitude rate, each input pulse at terminal 26 representing a 100 foot increment results in the state of the counter 11a being read out to a memory 220 and reset to a count of 100 (representing a maximum altitude rate of 10,000 feet per minute. Counters 70-77 (Fig. 6) and 110-117 are also reset by each incremental signal after a delay of 600 milliseconds, counter 70-77 then being pulsed by signals on terminal 64 at 7À5 milliseconds intervals. Initially with all the stages of counter 110- 117 reset a gate 120 is enabled to allow the signals on terminal 54 to increment via OR gate 81 counter 11a (Fig. 7). When this counter reaches a count of 74 decoder 11b sets stage 110  to disable gate 120 and enable a gate 90 so that the counter 11a is pulsed at half the frequency. The pulse rate of the counter is periodically halved (at counts of 53, 37, 26, 19, 13, 9, 7) until the next incremental pulse at terminal 26 results in its state being read out. The output of memory 220 thus approximates to the function Z = 100/t. Apparatus (Fig. 4, not shown) for determining whether the altitude is increasing or decreasing operates by examining at each incremental pulse the least significant bit and the next to least significant bit and the previous value of the next to least most significant bit.
