Title: Improvements in or relating to synchronisation circuit arrangements for use in television receivers
IPC: H04N5/12
Filed: 1953-09-09
Abstract: 756,678. Automatic frequency and phase control. COVILL, D. H. Aug. 12, 1954 [Sept. 9, 1953], No. 24910/53. Class 38 (4). The voltage controlling the frequency and phase of a line time-base oscillator, in a television receiver, is derived from a capacitor one terminal of which is connected to a point of fixed potential during each received sync. pulse and its other terminal being at a potential dependent upon the generator output voltage. The control voltage is derived from said one terminal through a low-pass filter and is of such sense that the sync. pulses occur at a predetermined point in the fly-back. The time-base generator 2 is coupled to a cathode follower 3, the cathode of which is connected to one terminal of the capacitor 4. The anode of pentode 1, which becomes conducting during the line sync. period of the television signal applied to its grid, is connected to the other terminal of capacitor 4. A resistance 5 shunting capacitor 4 completes the D.C. anode supply circuit of pentode 1 through valve 3. The control voltage developed across the capacitor 4 is fed to the generator 2 through a low-pass filter 6 ... 9. Frame sync. pulses are developed at terminal 10 of the screen-grid circuit of pentode 1 by the time-constant circuit 12, 13.

Title: Crease- and wrinkle-resistant fabrics
IPC: D06M13/52
Filed: 1964-06-17
Abstract: A crease- and wrinkle-resistant fabric comprising fibres of polyvinyl chloride or a copolymer which predominantly contains vinyl chloride monomer units, is obtained by holding the fabric under tension and maintaining it at an elevated temperature.  The polyvinyl chloride is preferably of a high syndiotactic index obtained by catalysed low-temperature polymerisation between -10 DEG C. and -60 DEG C.  As well as polyvinyl chloride fibres the fabric may contain natural or synthetic fibres, e.g. wool.  The process may be carried out either under dry or humid conditions and the heat may be transmitted to the fabric by hot air, steam, nitrogen or radiation under infra-red rays. The temperatures used for polyvinyl chloride fibres of a high syndiotactic index are from 110 DEG C - 140 DEG C, preferably from 130 DEG C - 135 DEG C.  The processing time may be from 10 seconds to 30 minutes, preferably from 1 - 10 minutes.  The treatment may be continuous, e.g. performed on a stenter, or intermittent, i.e. carried out batchwise.  The fabric to be processed may be unbleached or dyed. In the Example, a polyvinyl chloride fabric is darned, scoured, washed, centrifuged, dried at 90 DEG C. in a stenter, humidified, sheared, steamed to a free shrinkage and subjected to steam decatising.

Title: Lasers
IPC: H01S3/23
Filed: 1963-06-25
Abstract: 1,040,393. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 25, 1963 [June 27, 1962], No. 25155/63. Heading. H3B. The active element of a solid state laser is in the form of an elongated rod which is surrounded by a layer of cladding material, the latter being coupled to cooling means and also forming a lens for concentrating the radiation from a pumping source on to the active element. As shown in Fig. 5, the laser element 35 comprises a rod 38 of laser material, e.g. calcium fluoride doped with samarium or uranium ions and has its length and diameter so dimensioned that only one or a very small number of modes will be propagated when stimulated emission occurs. The cladding material 39 having a lower refractive index than the rod 38 is formed by dipping the latter in a solution of synthetic plastic. Alternatively the cladding material may be of glass. In the laser system of Fig. 5 the laser element 38 and filament 40 are positioned at the foci of the ellipse defined by members 41 and broken lines 42 so that an image of the filament is focused on the rod 38 of the laser element 35. The cladding material 39 has an enlarged semi-cylindrical portion 44 and a smaller semi-cylindrical portion 45, the latter being received in recess 46 of a copper heat sink 47 connected to a source of coolant 50. The portion 44 of the cladding material acts as a lens so that incoming light rays are accurately focused on the rod 38. In the embodiment of Fig. 6 (not shown), the rod of the laser element and the filament are disposed at the foci of two inwardly facing and spaced parabolic reflectors having highly polished interior surfaces. Filters may be inserted between the element and the filament to remove portions of the light from the filament which do not cause stimulated emissions to take place. The system of Fig. 8 uses a cylindrical lens for focusing the filament image on the laser element. In the amplifier system of Fig. 8 means are provided to stabilize the output. The intensity of light source 69 is controlled by and responsive to the input signals which it is desired to amplify, the light output from the laser element 35 passing through lens 71 and filter 72 to detector 73 which provides an electrical output. The pumping light from filament 40 maintains the laser element just below the threshold for stimulated emission in the absence of input signals to be amplified. To stabilize the amplifier the electrical output on conductor 74 is fed back over a loop comprising switching means 75, a compensating network 76 and a motor 77 to adjust the potential applied to filament 40 and hence the intensity of the pumping radiation.
