Title: Modulator-demodulator
IPC: H04L27/10
Filed: 1973-04-10
Abstract: 1429265 Data transmission; FSK systems INTERNATIONAL STANDARD ELECTRIC CORP 10 April 1973 [11 April 1972] 17128/73 Headings H4P and H4L A F.S.K. transceiver has a combined modulator-demodulator comprising a fully integrated common circuit to perform conversion of binary coded to frequency modulated signals reversely, which circuit comprises an oscillator, a frequency divider with reset device, a code to determine the ratio of the frequencies transmitted or received, and a comparator connected to the divider and encoder. The transmitting part of a F.S.K. transceiver comprises oscillator 1, frequency divider 2, comparator 3, encoder 4, signal transmitter, e.g. teleprinter 5 and a flip-flop 6 interconnected as shown and controlled by a switch CA. The frequency divider ratio is determined by decoder 4. When the nth condition of divider 2 is identical to the output condition of encoder 4, comparator 3 delivers a pulse which resets divider 2 to one of a pair of ratios, selected by switch 8 the output from which passes through filter 7 to line.  In a receiving condition zero crossings of incoming signals are detected at 31 and encoder 4 sends to comparator 3 a code corresponding to the central frequency. When coincidence occurs, comparator 3 delivers a pulse to flipflop 28 turning it on and at the following reset the condition is transferred to flip-flop 29 which stores the information until the next cycle; flip-flop 28 is reset via delay circuit 30.  If the signal/noise ratio is low compensation is made by applying the output to a shift register set at the rate of zero crossings and on which a two out of three majority decision is made. The arrangement is stated to provide signals without phase discontinuity provided that binary signals occur at the end of each division cycle which may be achieved by flip-flop 6.

Abstract: 834,010. Electric tests. VARIAN ASSOCIATES. June 4, 1956 [July 22, 1955], No. 17204/56. Class 37. The magnetic properties of matter are investigated by determining the absorption of radio-frequency energy in a varying magnetic field. In the arrangement of Fig. 2, the dotted lines enclose an oscillation detector which feeds radio frequency energy to a coil surrounding the specimen 9 under test and at the same time feeds anoutput to amplifier 6 and thence to the vertical plates of oscilloscope 7. A sweep generator 5 provides a low-frequency signal to sweep coils 3, 4 to alter the magnetization of the specimen under test and to control the horizontal sweep of the oscilloscope. The output to amplifier 6 is the envelope of the high-frequency modulated by the sweep frequency. In the absence of a specimen the waveform of Fig. 1A results. When the specimen is inserted or the arrangement brought near the ground the waveform of Fig. 1B is obtained. The arrangement described with reference to Fig. 2 may be used for detecting ferromagnetic materials in the sides of boreholes (Fig. 3, not shown).

Filed: 1951-07-20
Abstract: 701,756. Wind motors. OVIEDO, F. F. DE. July 20, 1951 [June 23, 1951], No. 17314/51. Class 110 (3) A wind motor comprising a vaned rotor mounted to rotate about a vertical axis and a surrounding series of screens acting so as to increase the velocity of the air passing through them and to direct the air so that the thrust on the vanes acts to turn the rotor in one direction, has the screens, which are of symmetrical faired section,: made hollow. The wind motor shown, Figs. 4 and 5, has eight screens 1, the direction of which corresponds to the continuation of the sides of an octagon inscribed in a circle on which their ends lie. The screens have a symmetrical faired section and a length P sufficient to obstruct the entry of the wind into the inactive zone or the rotor and may be arranged on the ground or on pillars which raise them to a convenient height. The number and direction of the screens is not an essential feature of the invention. For example the direction of the screens may be made the continuation of the sides of two squares the corners of which coincide with the apices of the octagon. The screens are hollow and adjustable but for high power motors they are preferably fixed to a cement structure. The walls of the screens may be formed of prefabricated material, of iron plate or fibre cement. The rotor consists of a square section framework 2 reinforced by bracing members 3 and struts 4 having vanes 16. Each vane 16 is made up of ten small vanes 17 which slide on T-members of the framework and are adjustable from the handwheels by means of chains. The vanes 17 are formed of a metal framework covered with hard aluminium sheet. The framework 2 is rotationally supported on the tower 9 by a plate 5, Fig. 6; mounted on a shaft 6 provided with bearings 7, 8. The rotor is centred and levelled by means of rubber rollers 12 acting on a toothed wheel 10 mounted on the lower end of the rotor. The friction of the rollers 12 is adjustable by means of screw gear 13, so that they may be used as a brake. The rollers 12 are used to transmit the power of the rotor to dynamos. The toothed wheel 10 may also be used to transmit energy to an additional dynamo 15.

Title: Improvements in testing extensible threads
IPC: G01N3/08
Filed: 1932-06-21
Abstract: 404,680. Testing extensible threads. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, MURPHY, E. A., and JAMES, R. G., Fort Dunlop, Birmingham. June 21, 1932, No. 17505. [Class 106 (ii).] Threads composed wholly or partly of vulcanised rubber are continuously tested by drawing the thread between successive pairs of traction rolls having grooved surfaces between which the thread is extended under a load the displacement of which releases the tractive effort of one of the pairs of rolls by deflecting the thread to pass through one or other of the grooves recessed into the roll surfaces. One of the lower pair of rolls 3 is driven by hand or power, the drive being continued through a reduction gear to one of the upper rolls so that the lower pair 3, 4 receive more quickly than the upper pair 1, 2 which determine the rate of supply. The diameter of the roller may be arranged to give this effect and several pairs of rolls used so that several threads may be simultaneously tested. The diameter of one or both of the lower pair of rolls is reduced preferably gradually at first and then more rapidly to provide a groove 5 by which the grip of the roller on the thread may be reduced or completely released. The thread 6 is passed between rolls 1, 2 and then carried horizontally on a pulley 7 running on guides 11 and then downwardly between rolls 3, 4. The pulley 7 is attached by a flexible connection 13 passing over a pulley 14 to an adjustable weight 15. The latter is connected by a system of levers and links 16, 18, 20 to a fork 22 which moves transversely across the path of the lower member 9 of the loop. If the thread is of uniform texture and tensils strength, the floating pulley will settle to a position from which it will make no appreciable forward or backward movement. If now a weak portion moves into the test bight, the pulley will retreat from the rolls. This causes the link and lever motion to move the fork so that the thread is gripped between the lower pair of rolls which being faster than the upper pair reduce the length of the bight and cause the weight to move upwards and the deflector fork to move the thread to a position of less grip. Stops 12 prevent the pulley receding too far on breakage. The incoming free end is then guided to the groove 5 and the thread re-engaged with the pulley.
