Title: Improvements in flexible shafts for passing through drains, conduits or the like
IPC: F16C1/08
Filed: 1922-05-04
Abstract: 200,278. Ward, E. A. May 4, 1922. Cleaning internally, non- rotary appliances for; piillthrough rods.-The sections of flexible shafts or rods for passing through drains, pipes or other conduits are formed from a number of straight resilient steel wires held clustered together in parallel relation by coating them with, or dipping them in, molten metal. The wires 1 are arranged around a central wire 2, which is preferably of larger diameter, and are dipped in molten solder or other metal which penetrates the interstices between the wires and binds them together to form a single rod which is approximately circular in cross-section. The rod is then sheathed, either for a short distance near its ends, or along its whole length, with a helically-wound flexible metal strip 3, the space between the sheathings in the former case being sheathed by winding string 4 thereon. An outer sheathing 5 of helicallywound spring metal strip completes the rod which may be then varnished and provided with bands or collars at intervals along its length. Alternatively, the rod may be finished to circular cross-sec. tion after coating with the metal, or a sheathing of adhesive insulating tape may be applied. The sections are connected together in any known manner, male and female coupling members 10 and 9 respectively being attached at the ends for this purpose. The inner ends of the coupling members are shaped as shown in Fig. 2, the cone part 13 holding a hollow cone 14 integral with, or formed from a metal blank and inserted into, the coupling member. The ends of the central wire 2 of the rod is inserted into the hollow blank 14, the wires 1, which are free at their ends, being simultaneously spread by the outer face of the blank 14, and molten metal 15 poured into the space 13 to secure the coupling member to the rod.

Patent GB-1521296-A (GB)
Title: Circuit arrangements for demodulating chrominance television signals
IPC: H04N9/455
Filed: 1975-07-16
Abstract: 1521296 Television receivers INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 16 July 1975 [25 Oct 1974] 12903/78 Divided out of 1521295 Heading H4F A receiver for a PAL or S.E.C.A.M. television signal includes a single synchronous demodulator which is fed with the chrominance signal. When a PAL signal is received the demodulator is also fed with a reference subcarrier switched in phase at line frequency. When a S.E.C.A.M. signal is received the demodulator is fed with a modified form of the chrominance signal. In both cases the demodulator output consists of the two colour difference signals, alternately at line frequency. In the embodiment illustrated (Fig. 4) when a PAL signal is present at C' colour bursts separated by gate 54 cause generator 58 to provide a subcarrier in phase with the -(B-Y) signal. The subcarrier is fed via a half line frequency switch 59 direct or via 90 degree shifter 61 to demodulator 55, which provides R-Y and -(B-Y) signals alternatively. These signals pass, via resistor 63, switch 62, and amplifier 67, both directly and via a oneline delay 76 to a switch 75 which outputs the R-Y and -(B-Y) signals simultaneously to a PAL matrix. When a S.E.C.A.M. signal is received the bursts fed to gate 58 are not of the frequency necessary to operate the generator 58. The lack of an output from 58 is detected (60), causing a switch 53 to close. This allows the received signal to pass to unit 56 whose output phase-varies linearly with frequency and is fed to the demodulator 55, which operates now as a frequency discriminator. The demodulator output passes to a de-emphasis circuit 64-66, slected by switch 62, and D.C. clamp 68, 70, 73, and on to the amplifier 67, &c. Switch 62 is controlled in the same way as switch 53. To ensure that the ratio of the amplitudes of the signals at the output of the circuit is correct the signal fed to the demodulator 55 passes via a limiter 52 whose threshold is switched at half line frequency between limiting values in the ratio 1:1À16. The limiter has no effect upon the PAL signal since the a.g.c. operative when PAL is received maintains the signal below the lower limiting value. Whichever type of signal is received a frequency selective amplifier 79 selects the half line frequency component resulting from the demodulated bursts. This component controls the phase of bi-stable 72 which, in response to line frequency pulses H, generates a half line frequency signal. If the component disappears unit 80 generates a colour killer signal to control amplifier 67.

Abstract: 1362477 Cathode-ray tube displays; generating scanning waves SINGER CO 21 March 1972 [1 April 1971] 13113/72 Headings H4T and H3P The beam spot 19 (Fig. 1) of cathode-ray tube 15 is scanned across the screen in such manner that it appears to trace a predetermined path as viewed from eyepoint 11 via beam splitter 17 and spherical mirror 13 at the centre of curvature of which the point 11 is located. Fig. 2 shows a desired, predetermined path comprising a raster each horizontal line 31 of which is an equal angular segment of a line of latitude and must be scanned in equal time intervals. Point 33 is the centre of the display and corresponds to the intersection with the display of the line 35 (Fig. 1) so that every point on the display, the dimensions 37 and 39 being known, may be defined by an azimuthal (horizontal) and elevation (vertical) parameter with reference to the axes of Fig. 1. Thus the voltages (provided by a computer 27) controlling the deflection Vx, Vy are each a function of azimuthal angle (X scan) # and of elevation angle (Y scan) # and are assumed to be represented by the polynomials Vx = K 1 # + K 2 #<SP>2</SP># + higher order terms Vy = K 3 # = + K 4 #<SP>2</SP># + higher order terms Voltages corresponding to # and # may be produced by integrating a constant voltage periodically (e.g. producing normal scan waveforms) in 43, 45 (Fig. 3) and known techniques employed to produce the power terms and the cross multiplied valves which are then combined in scanning amplifiers 55 and 57, the multiplications by the constants K1 ... K4 being provided by the resistors 59 and 61 the values of which are determined by the polynomial coefficients. The latter values may be determined by the "method of least squares" which involves the development of three dimensional ray trace data for a matrix of points (as viewed from position 11) such as the X's of Fig. 2 and then finding the values of #, #, Vx and Vy for each such point and employing a digital computer to evaluate the polynomial coefficients by the method of least squares. Other methods of determining such coefficients are described.
