Title: Improvements in or relating to the recording and reproduction of sound on photographic films
IPC: G11B7/00
Filed: 1931-03-04
Abstract: 367,574. Photographic sound records; optical apparatus. KODAK, Ltd., Kodak House, Kingsway, London.-(Assignees of Capstaff, J. G. ; Kodak Park, Rochester, New York, U.S.A.) March 4, 1931, No. 6696. Convention date, March 5, 1930. [Class 40 (ii).] Sound is recorded on lenticulated photographic films by transmitting through the lenticulations or lens elements of a moving film 5 light radiations which vary in accordance with the sounds to be recorded, and such record extends over a part or substantially the whole width of the film. The film 5, Fig. 1, which is provided with a sensitized layer 6 on one surface and transversely disposed lens elements 9a, 9b on the other surface, is moved over a curved plate 8 having a transverse slot 10. A source of light 13, which may be adapted to produce either variable width or variable density records, is disposed at the centre of curvature of the plate 8 so that the lens elements successively record on sections or strips 11a, 11b, 11c. A discontinuous picture record may be provided on interspersed sections 12a, 12b, 12c, or a second sound record may be recorded on the interspersed strips by a second light source 14. Reproduction from such a film may be effected by passing the film 15, Fig. 6, continuously over a curved plate 16 having a slot 17 through which light is projected from a source 18 through a lens 25. A photo-electric cell 19, in circuit with a loud-speaker 21, is arranged either at the centre of curvature of plate 16 or other position corresponding to that of the recording light source. To record on a film having longitudinal lens elements 9a, 9b, 9c, as shown in Fig. 5, an objective 30, which is furnished with a mask 31 having an aperture 32 therein, is disposed adjacent the lenticulated side of the film, and light is projected through a slit 34 adapted to be varied in width in accordance with the sound variations. The light passing through the aperture 32 illuminates only a portion of the object field of the lens elements 9a, 9b, 9c, so as to record the sound records 27a, 27b, 27c. By moving the mask 31 so that the aperture 32 is in the position 36 the records 26a, 26b, 26c are recorded. If desired, three records may be made behind each lens element. Instead of an objective and mask, a light source may be disposed at various positions transversely of the film so as to produce a corresponding number of records.

Title: Method and apparatus for the measurement of the thickness of metallic and other conducting coatings on backings of conducting materials
Inventor: HEATH ALFRED RUSSELL
IPC: G01B7/06
Filed: 1954-03-08
Abstract: 768,448. Electric tests. BRITISH NON- FERROUS METALS RESEARCH ASSOCIATION. June 2, 1955 [March 8, 1954], No. 6707/54. Class 37. The thickness of a conducting coating on a conducting backing is determined by applying heat to, or abstracting heat from, a point on the coated surface and observing the thermo-electric potential so generated by connecting this point through a sensitive potential-measuring device to a second point on the coated surface. The invention is illustrated as for measuring the thickness of a nickel coating on steel and using hot and cold nickel probes. In Fig. 1 the two probes 1, 2 contact coated surface 13 and the potential shown by measuring device 7 is compared with a calibration curve obtained with the same apparatus applied to a series of standard pieces of known thicknesses of coating. Each probe 1, 2 is a stout nickel rod formed to a ball point and embedded in a lead cylinder 3 or 4. The hot probe 2 has a transformer-fed heating element 10 embedded in plaster 9; probe 1 is also surrounded by plaster 8. In a unit twoprobe assembly, Fig. 2, the hot nickel probe 14 heated by winding 15 has a ball point 23 of diameter 0.02 inch pressed against the test surface by a spring 21. Insulating tube 17 surrounding probe 14 screws into a perforated insulating disc 18 which in turn screws into a conical brass casing 19 having nickel contact pins 20 which form the cold probe. The probe unit of Fig. 2 may be supported by a swinging arm counter-balanced or spring controlled so that by applying a suitable weight the probes are pressed into contact with the test surface. The probe points may be rotatable and maintained in contact with workpieces arranged on a conveyer belt and by a suitable relay system actuated by amplified probe signals faulty workpieces giving readings higher or lower than a pre-selected tolerance can be automatically removed from the conveyer belt.

Title: Controlling the signal frequencies in television systems
IPC: H04N7/12
Filed: 1935-03-05
Abstract: 451,610. Television. MAGUIRE, I. L., 12, Thackeray Street, Elwood, Victoria, Australia. March 5, 1935, No. 6885. Convention date, March 6, 1934. [Class 40 (iii)] The reproducing light is modulated by a single signal derived from the differential effects of two signals which are separately derived from the simultaneous scanning of similar areas A1, A2, identically located on separate similar images I1, I2, but one scanning area A1 including an elementary area l additional to those included in the other scanning area. The differential signal thus represents the additional elementary area. The width of each scanning area increases along its length according to a sine law, and the maximum width h is equal to the width of a scanning-line. The light passing the respective scanning areas falls on separate cells connected in differential circuits, or the two signals may be transmitted separately and a differential circuit used at the receiver, or the two signals modulate two light beams in opposite senses, Figs. 7a and 7b (not shown). The scanning may be performed by a mirror drum, Fig. 4 (not shown), or by cathode-rays, Fig. 6 (not shown). The scanning areas may be equal, with one leading the other by the length of an elementary area, Fig. 5a (not shown).

Title: Sewing machine motor speed controllers with illumination means
IPC: D05B69/18
Filed: 1953-03-12
Abstract: 724,444. Controllers. FAIRWEATHER, W. C. (Singer Manufacturing Co.). March 12, 1953, No. 6902/53. Class 38 (3). A foot-operated carbon compression rheostat for an electrically driven sewing machine is contained in a control unit which has a transparent pedal slide block 22 illuminated from a neon glow lamp 69 within the casing of the unit for indicating the position thereof. The rheostat comprises stacks 37 of carbon discs connected to terminal 38 and to a compression head 39. A pull on rod 41 first closes a circuit through the rheostat and applies an increasing pressure to the stacks 37 which gradually 'lowers the electrical resistance. Greater pressure is applied to the rheostat at the later stages of movement of the pull-rod by means of a backing spring 42 which co-operates with a weak bow spring 40 and a coil recovery spring 43. The pull-rod 41 is actuated by means of a cross bar 52 carried on a pivoted member 47. which is coupled to the pullrod by strap 45 and nut 44. As the cross bar 52 is depressed the effect of recovery springs 53 is weakened to compensate for the cumulative mechanical resistance of the springs 40, 42, 43. The pedal 22 straddles the lever 47 and rests upon the cross bar 52. A plate 67 and strips 66 constitute a short-circuiting switch for the rheostat when it is fully compressed. The lamp 69 is illuminated whenever the foot controller is connected to the supply source, and, as shown, is connected in parallel with the carbon piles so that it will be shunted out of circuit as the resistance of the rheostat is reduced. When the machine is employed in a cabinet the motor and the control unit are wired to the same socket member. With a portable machine, there is a plug-andsocket connection betweenthe motor and the controller. The indicating lamp may be arranged directly across the supply source so that it will be unaffected by the actuation of the carbon piles.

Title: Improvements in apparatus for drawing tubes of glasses, for example quartz, of high silica content
IPC: C03B17/04
Filed: 1938-03-08
Abstract: 490,503. Drawing glass and silica tubes. GENERAL ELECTRIC CO., Ltd. March 8, 1938, No. 7245. Convention date, March 12, 1937. [Class 56] Relates to apparatus for drawing tubes of quartz, or of glass having a high silica con. tent, and of the type in which the molten material flows through an annular aperture or die in the bottom of a heated container. According to the invention, the container and die are made of a refractory oxidizable metal, the container is heated by an electric furnace closely surrounding it, and streams of gas are used to protect the metal from oxidization and to prevent the deposit of silica on the surface of the drawn tube. The container 1 is made of molybdenum sheet, although tantalum or tungsten may be used, and its lower end is fitted with a plate 2 with a central aperture. A molybdenum tube 3 has a thickened end 4 which is supported. in the aperture, and the silica flows through the annular space around the tube and is drawn away by suitable mechanism 20, 21. The furnace consists of a cylinder 7 of refractory insulating material, such as zirconia, provided with a molybdenum heating-resistance 9 on its interior surface and a water jacket 8 on its outer surface. The ends of the furnace are closed by water-cooled metal covers 10, 11 which serve as terminals for the resistance 9. The top of the tube 3 is connected by a threeway cock 16 to a gas supply pipe 17 and to a pipe 18 leading to the atmosphere. In operation, a gas which is neutral or reducing and does not attack heated quartz is introduced into and around the container to protect the molybdenum. At the start of the operation, gas is forced through the interior of the drawn tube and issues from its open end. When a sufficient length of the tube is cooled, a pipe 23 is attached to its open end and gas is blown upwards through the tube and through the pipe 18 into the atmosphere. Specification 372,848 is referred to.

Filed: 1966-10-07
Abstract: 1,171,627. Character recognition. H.M. POSTMASTER GENERAL. 10 Oct., 1967 [7 Oct., 1966; 16 Feb., 1967], Nos. 45045/66 and 7560/67. Heading G4R. In a character recognition machine, the character is stored in a matrix of storage cells which are then scanned from a predetermined one of the cells, examining the cells adjacent to it in a predetermined order, moving to the first storing a portion of the character, examining the cells adjacent to this cell, and so on, whereby the character is expressed as a sequence of movement directions. The character is scanned and copied into a first matrix of storage cells. The size of the character is determined to fix a parameter D. Under computer control the cells of the matrix are considered in turn starting at the top left corner and moving along each row in turn to locate the character. When a point of the character is reached each character branch of length greater than D therefrom is followed in turn, gaps of a size determined by D being filled in and the resulting smoothed character being established in a second storage matrix with progressive clearing of the first matrix. Both matrices are consulted during the process. When all branches from a given character point have been followed the row-by-row search continues. A chain code representing the character as a sequence of 1 out of 8 equally-spaced directions together with node indicators is developed. For each node, an identifying number is assigned and the co-ordinates of the node and the number of branches at the node are specified. The contents of the second matrix are now transferred to the first matrix (since cleared). A starting point on the character (in the first matrix) is obtained as before except that the row-by-row search only extends halfway across the width of the character, and when a character point is found the computer hunts in a 3 x 3 square of cells around it for a node having a higher number of branches than the starting point this node, if found, being taken as the starting point instead. Ceriphs &c. at the starting point are eliminated in this way. The ignoring of branches shorter than D eliminates them elsewhere. The character is followed and transferred to the second matrix with line thinning (except at nodes), the second matrix being consulted before a given branch is transferred to ensure that no branch from the same point in the same direction has already been transferred. A chain code for the character now in the second matrix is derived as before and simplified by eliminating fluctuations from average directions to some extent and then by eliminating all but one of each sequence of identical direction indicators. The reduced chain code is compared with reference codes to identify the character, allowance being made for variants, including alteration of the chain code in a mechanical way (described) to compensate for angular misorientation of the character.
