Title: Gauge control for multistand rolling mill
Inventor: DORNBUSCH PAUL EDGAR
IPC: B21B37/16
Filed: 1969-11-21
Abstract: 1282573 Automatic control of rolling GENERAL ELECTRIC CO 21 Nov 1969 [21 Nov 1968] 57195/69 Heading G3R In a rolling mill, a signal corresponding to a measurement, between successive stands, of deviation in the thickness of the rolled material, is delayed in dependence on a measurement of roll speed and utilized to control the speed of one or other of the stands after division and multiplication by further signals so that the thickness is maintained constant. In Fig. 1, deviation from a desired value of the thickness of metal strip 15 being rolled is detected by an X-ray gauge 19 the output of which is applied to an analogue to-digital converter 27. This error signal is then subject to a delay at 29 equal to the time taken for the strip to travel from gauge 19 to the next roll stand 12. The delay is obtained by applying the signal from a tachometer generator 21 associated with the previous roll stand 11 to an integrator-amplifier 23 having capacitive feedback so that, after a time dependent on mill speed, the integrator output is sufficient to transfer the signal from analogue-to-digital converter 27 to a digital-to-analogue converter 31. The ratio of the error signal to a signal 35 representing desired thickness is formed at 33 and multiplied by a signal 43 representing the speed of roll stand 11 so that a correction signal is produced at 37 representative of the amount by which the speed of roll stand 11 needs to be adjusted to remove the thickness error by varying tension. This correction is effected automatically by applying to correction signal to a speed controller 39. Integrator 23 is adjustable to allow for the delay inherent in the control system. Controller 39 may, alternatively, adjust the speed of roll stand 12.

Preferably the composition contains both virus-like particles and free double-stranded ribonucleic acid or a salt thereof, said RNA being obtained from the virus-like particles of the mould Penicillium stoloniferum. The compositions may be administered topically or by systemic injection to the animal before it becomes infected with the infective virus and may be administered on repeated occasions during the period when the animal is susceptible to infection. Protection has been achieved in a variety of animals, e.g. against Coxsackie B1 virus, Semliki Forest virus, vaccinia virus, foot and mouth disease virus, vesicular stomatitis virus, rabies virus and influenza virus. Virus-like particles having antiviral activity can be extracted from a medium in which the mould Penicillium stoloniferum has been grown by separating the mycelium of the mould from a culture medium in which it has been grown, treating the culture medium with RNA or a salt thereof, adjusting the pH of the resulting liquor to a pH of 3 to 6, separating the resulting precipitate from the supernatant, concentrating and purifying a suspension of the precipitate, e.g. by ultrafiltration and differential sedimentation, to yield the virus-like particles. Double-stranded RNA can be extracted from the virus-like particles so obtained by deproteinisation.

Abstract: 695,996. Sparking plugs. THIES, A. April 5, 1951 [Nov. 27, 1950], No. 7916/51. Class 7 (iv). In a sparking plug having a suppressor resistance element 8 resiliently mounted between the inner end of the central electrode 6, which is surrounded by an insulating jacket 5, and a contact piece 10, the latter is resiliently and slidably guided in the plug, and the ignition lead, not shown, is connected thereto so that hightension voltage is conducted directly from the contact piece 10 to the resistance 8. The electrode 6 is fastened and hermetically sealed to an inner wall of the plug body 2 by pressed-in metal rings 7 whilst the resistance of 10,000 ohms or more is arranged between a nut 9 on the electrode 6 and contact piece 10. The latter is secured to the walls of the main tubular insulator 12, which lines the interior of the body 1, by a ring 11. A tension or compression spring 14, which is located between a flange on the top or bottom of the contact piece 10 and the ring 11, combats the effects of vibration and temperature, the ring 11 being secured by pressing it inside the main insulator so that the ring, body 1 and insulator 12 constitute a condenser by which the normal capacity between the ignition cable and earth is considerably increased. A further increase in capacitance is obtained by disposing between the ring and the insulator a metal sleeve 15, which latter may be replaced by spraying metal on the inside of the insulator. The resistance 8 is slidably mounted and centrally disposed in the insulator by insulating rings 16, 17, whilst the plug is screened by extending the walls of the plug body beyond the contact piece 10. In a modification, the ring is in two parts in order to facilitate ready exchange of the resistance, one part comprising a split nut with an internally threaded conical-portion that receives the conical thread of the other part, in which latter the contact piece is slidable. The ring may either be made of vulcanized fibre with a conductive coating or of metal such as copper.
