Title: Method and apparatus for side band limitation of modulated oscillations
IPC: H04B1/68
Filed: 1932-02-29
Abstract: 384,492. Wireless transmitting and receiving systems ; valve modulating circuits. DITSCHE, W., 26, Kratkestrasse, Friedrichsfelde, Germany. Feb. 29, 1932, No. 6085. [Class 40 (v).] In a modulating system, the modulating wave is given a stepped form with the object of eliminating or reducing the side-bands. The modulating wave from a source LF is applied to the grid circuit of the modulating valve V, through a rotary switch S1 operating at a frequency higher than that of the modulation. When contact is momentarily made, the conductor C is charged and owing to the high value of the leak W, its voltage remains substantially constant until the next contact. A stepped voltage is thus applied to the grid of the valve V1, which modulates the wave generated by the valve V2 in the normal manner. This wave may be directly radiated, or it may pass through a second rotary switch S2 arranged to cut off the radiation at the moments when the modulating voltage is changing. When no radiation is taking place, the carrier wave energy may be absorbed by a circuit T2. The switches S, S2 may be replaced by valves opened and blocked by varying their grid voltage. The Specification states that one of the interacting waves in a superheterodyne receiver may be given a stepped form.

Abstract: 234,567. Clayton, J. W. March 13, 1924. Clipping, cropping, and shearing.-A scray for use with a single-cylinder perpetual shearing machine comprises a framework having two sides 1 stayed together, and an inclined platform 24 with horizontal portions at either end. A narrow rectangular turntable 21, forming one of the horizontal portions, is mounted at the rear end of the scray, on which the cuttled cloth is delivered from the machine. The turntable 21 is then given a quarter of a revolution and the cuttled pile slid down the inclined plane 24 to the other end of the platform to facilitate re-cuttling. In the Figure, a second piece D of material is shown which is operated upon successively after the piece C has passed through the machine, the two pieces being attached temporarily to one another. In this case the pile 4, before being operated upon again, is only slid partially down the incline until the other end is clear. The platform 24 comprises a number of boards of suitable length to pass between the sides 1 of the framework which are mounted thereon at the front end and on the inclined portion. A crossbar is provided at the rear end with a central bearing for the turntable. Stop-pins are provided on the under side of the turntable which engage recesses in the cross-bar when the table is transversely disposed to the platform.

Title: Corrector for a measured volume meter
IPC: G01F15/04
Filed: 1975-02-15
Abstract: 1529224 Measuring volume electrically UNITED GAS INDUSTRIES Ltd 4 Feb 1976 [15 Feb 1975] 6516/76 Heading G1N A volume corrector for a gas volume meter is mounted in a flameproof container. The output from a turbine meter 16 is fed via a pulse shaper 30 to a bi-stable circuit 14 so that the leading edge of each pulse switches 14 whereby a gate 13 is opened to allow pulses from a crystal oscillator 12 to pass to counter 18 via divider 19. At the same time the output of 14 open circuits transistor 16 to allow a gas temperature signal on line 21 to be integrated by 15. The integrated signal is compared in comparator 25 with a gas pressure signal obtained from a strain gauge resistance bridge and when the integrated signal is equal to the pressure signal the comparator output switches 14 which closes the gate 13 and resets the integrator 15. Thus the number of pulses counted at 18 is a function of meter pulse frequency as modified by the gas temperature and pressure. All of the signal lines entering the corrector include Zener diodes 36, 37, 38, 39 and 40 to limit the signal energies to a safe amount. Gas law deviation coefficient can be corrected for by changing the oscillator frequency. Counter 31 gives an uncorrected meter reading and meter 35 indicates the value of the correction factor. Housing. Fig. 2. A cast iron box 41 is divided into three compartments, the front compartment 42 provided with a window 44 housing the circuitry and indicators. The former being mounted on boards 46 and the Zener diodes are mounted at 47. The rear of the box is divided into two compartments one of which 50 houses the terminals and circuitry for the input lines 11, 28, 21 and the strain gauge. The other rear box is the mains terminal compartment. In use the box 41 is mounted on to a high-pressure gas meter.

Title: Connection for co-relating or combining several variables

Abstract: 655,765. Electric indicating systems. KLASEK, V. March 3, 1948, No. 6654. Convention date, March 3, 1947. [Class 40 (i)] [Also in Group XIX] In apparatus for combining or co-relating the values of several variables (e.g. in the regulation of steam boilers in response to water level and the quantities of steam produced and water supplied) the sliders of potentiometers 2, 3, 4, 5 (Fig. 1), are deflected in accordance with the respective values of four variables. The sliders of the potentiometers 2, 3 are connected to an A.C. source 1 and the sliders of potentiometers 4, 5 are connected together through a centrezero D.C. measuring instrument 7. The ends of the pairs of potentiometers 2, 4 and 3, 5 are respectively connected together through reversely-connected dry or thermionic rectifiers 6. Negative half-cycles pass through the upper, and positive half-cycles through the lower, rectifiers of each pair, and their amplitudes are respectively proportional to the total resistance values of the lower and upper portions of the potentiometers. Thus the measuring instrument will read zero when the sliders are all at the potentiometer midpoints and at other deflections its reading will be proportional to the mean of the values deflecting the sliders, taking the midpoint as zero in each case. For less than four variables, one or more sliders may be fixed at the midpoint. Contacts operated by the instrument 7 may control, e.g., the supply of boiler feed-water.

The polymer or prepolymer may be a polyurethane polymer containing free isocyanate groups, an epoxy resin, a halogen-containing hydrocarbon polymer, a chlorosulphonated polymer, a polymer containing acid halide groups, a polymer containing anhydride groups or an organopolysiloxane. Most preferably the complex is derived from 4,41-methylene dianiline and lithium chloride or sodium chloride. The inert carrier liquid must not promote rapid decomposition of the complex, must be unreactive toward the polymer or prepolymer and must be readily miscible therewith. Suitable inert liquids are di-(2-ethylhexyl)phthalate, a commercial aromatic process oil, and tetraethylene glycol bis-(2-ethylhexanoate). A surface active agent, e.g. lecithin may be included in the dispersion. Curing takes place by heating the reaction mixture to a temperature above the temperature at which the complex dissociates.
