Inventor: GOELL JAMES EMANUEL
IPC: H04L27/12
Filed: 1967-09-19
Abstract: 1,195,216. Frequency modulation; digital transmission systems. WESTERN ELECTRIC CO. Inc. 19 Sept., 1967 [28 Sept., 1966], No. 42567/67. Headings H3R and H4P. Digital data is transmitted by means of a voltage-controlled relaxation oscillator fed by D.C. pulses from an encoder via a low-pass filter. The frequency-modulated output passes via a band-pass filter to the transmitter output. The band-pass filter is tuned to the base frequency of the oscillator, the modulated frequency varying above and below this frequency in dependence on the pulses fed to the oscillator. The output of the oscillator is substantially shorted to bit-rate frequency by an inductor. The low-pass filter prevents the oscillator frequency feeding back to the encoder.

Abstract: 1,268,150. Moulding closures. CONTINENTAL CAN CO. Inc. 7 Sept., 1970 [27 Oct. 1969], No. 42694/70. Heading B5A., [Also in Division B8] In a method of moulding a plastics closure 10 including a thin web 18 defining a weakening line whereby the central area 19 may be easily torn from the remainder, the plastics material is injected at 46 into a mould cavity provided between mould assemblies 26, 28 movable between open and closed positions. The web is formed between ribs 42, 54 of rings 41, 53. respectively, which surround plates 31 and 49 of the mould assemblies. In the mould closed position the formed web is made thicker than that required in the finished closure, but when the mould is opened the rib 42 moves upwardly relative to the rib 54 to narrow the web thickness and, simultaneously, a stripper ring 34 is moved downwardly by springs 37 to retain the closure on the assembly 28. An ejector ring 51 is finally raised to eject the closure, during which the rib 54 acts on the opposite face of the web and may further reduce its thickness. Coolant channels 47, 48 and 50 are located in the mould parts and heat transfer from the rings 41, 53 is minimized by recesses 40, 55 so that when the mould is opened the material of the web remains workable.

Abstract: 1,237,287. Rolling mills. KAISER ALUMINUM & CHEMICAL CORP. 9 Sept., 1968, No. 42872/68. Heading B3M. [Also in Division G3] A desired roll gap is maintained in a rolling mill by the operation of separate hydraulic prestressing and roll bending systems, the systems being interlocked for interdependent operation. In a 4-high arrangement, cylinders 33 urge the lower backing roll 14 upwardly with a constant force. The force is held constant by a feedback system incorporating, for each side of the mill, a load cell 76 which measures the force on the roll, using rods 74, a potentiometer 72 for setting a desired force, and an amplifier 70 which controls a valve 66 to reduce any difference between the measured and desired values of force. A similar feedback system controls the pressure exerted in bending cylinders 42, a potentiometer 74<SP>1</SP> setting a desired pressure, and a sensor 82 measuring the actual load. The amplifier 76<SP>1</SP> which controls the bending pressure has a further, adjustable, input from an auxiliary summing amplifier 86. The amplifier 86 is provided with pressure signals from both the feedback systems and serves to make the systems interdependent. In an alternative control system (Fig. 3, not shown), the measuring rods 74 and load cells 76 are dispensed with, and the operation of the prestressing control valves 66 is dependent on the pressures in the prestressing cylinders 33 and on the bending pressures in the cylinders 42. The work rolls of a 2-high mill may be controllably bowed using the invention.

As described, the processor is preferably a contractility unit for measuring a signal derived from the heart which may represent e.g. the left ventricle pressure or the apex beat. In order to calibrate the processor, an exponential wave, Fig. 2, is produced when the circuit shown in Fig. 4 is switched to the input of the processor. Fig. 4 comprises an operational amplifier 9 having positive and negative feedback paths via resistors R. Its operation is explained mathematically. When switch 8 is closed, capacitor Cl discharges and the action of amplifier 9 provides the negative going exponential curve of Fig. 2. The positive-going exponential curve is produced by opening switch 8 and closing switch 7. A flat top to the waveform shown in Fig. 2 is produced by leaving switches 7 and 8 both open. During the negative-going slope of Fig. 2, the processor provides a negative-going pulse of magnitude 1/RC and a corresponding positive-going pulse during the rise in the waveform shown in Fig. 2. A calibration source only producing an exponential in one direction may alternatively be used.

Abstract: 1,165,870. Cracking by regenerative furnaces. UNION CARBIDE CORP. 14 Sept., 1968, No. 43847/68. Heading C5E. In an otherwise conventional process for cracking hydrocarbons to produce, for example, ethylene and/or acetylene by means of a cyclically operated regenerative furnace having 2, 3 or more regenerative masses spaced apart to form 1, 2 or more (respectively) combustion spaces into which fuel gas injection means lead, a cool purge gas (e.g. steam, H2, N 2 or CO 2 ) is injected through said injection means to cool the same at all times when fuel gas is not being injected therethrough. The nozzles of the injection means are thereby made less susceptible to thermal damage and attain longer life. The supply of purge gas is controlled by reducing pressure valves which open when the fuel gas pressure drops below a predetermined value and close when it exceeds said value. The pressure of purge gas is desirably maintained above the furnace pressure to prevent back-flow of reaction gases into the injection means which would otherwise cause coking or clogging.
