Title: Aperture correction circuits
IPC: H04N5/208
Filed: 1970-01-09
Abstract: 1299842 Television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 9 Jan 1970 [14 Jan 1969] 1171/70 Heading H4F Vertical aperture correction of a picture signal from vidicon 1 in which interlaced scanning is employed, is effected by passing the signal via one line delay circuits 11 and 12, phase inverters 13 and 15, and divide by two circuits 14 and 16 to an adder 17 as shown. The output L n  from adder 17 comprises l n -¢(l n-2 +l n+2 ), where l n  represents the picture signal of the nth line, it being assumed that the [n+ 2) line is applied at input 10 (l n  and l n-2  are derived therefrom due to the interlaced scanning). Output L n  is applied (optionally through amplifier 18 having an amplification factor of α) to adder 19 to which the picture signal l n  delayed by one line is applied, the resulting aperture-corrected picture signal l n  + αL n  being only a rough correction since adjacent picture elements are not compared, i.e. the nth line is compared with the (n-2) and (n+2) lines. To obtain a finer correction signal, L n  is applied to a memory tube 21, e.g. a flooded camera tube, which effectively operates as a circuit having a delay approximately equal to one field period and an output voltage C n  which corresponds to the difference which occurs in L n  from field to field. This signal C n  is applied through amplifier 29 having an amplification factor of # and added to l n  to form vertical aperture-corrected signal l n +#C n  (the connection between adders 17 and 19 being removed). Fine correction signal C n  may alternatively be derived from L n  by means of a delay line having a delay of one field period minus half a line period and a one line period delay line in series arranged similar to the first correction circuit 11-17 so that C n  = L n  - ¢(L n-1  + L n+1 ). A fine aperture correction is obtained using signal C n  for scenes without moving components, but if the scene has moving components production of a dark area behind a moving bright component is avoided by using coarser correction signal L n . A combined correction signal αL n  + #C n  may be used.

Title: Textile-like nonwoven fabric
IPC: D04H1/62
Filed: 1957-01-11
Abstract: 833,697. Agglutinated fibrous fabrics; paper. DRELICH, A. H., and GRISWOLD, H. W. Jan. 11, 1957 [Jan. 11, 1956], No. 1185/57. Drawings to Specification. Classes 96 and 140. A washable non-woven fabric, e.g. paper, comprising a layer of overlapping, intersecting fibres and a water-resistant binder material distributed in a multiplicity of very small areas of the layer in accordance with a predetermined pattern and bonding together fibres passing through the areas, the average size of the areas being at least 0.000012 square inches and not more than 0.0028 square inches, and the distance between adjacent areas being not less than 0.01 inches and not more than 0.06 inches and the proportions of binder to fabric being such that the fabric is washable and has a degree of softness and absorbency not substantially inferior to that of the fibre layer without the binder material. Natural fibres of animal or vegetable origin and artificial fibres may be used. Specified fibres are viscose rayon, cotton, nylon, cellulose acetate and woodpulp. Specified binders are polyvinylacetate, -chloride, -butyral, -formal, polyvinyl alcohol, together with formaldehyde- or dimethylol-urea and a catalyst, co-polymers of butadiene with acrylonitrile and/or styrene, co-polymers of polyvinyl acetate with lower alkyl acrylates, polymethane, polyethylene, ethyl cellulose, nylon and cellulose acetate. The fabric of the invention is made by depositing the binder in small areas on the layer of fibres and then treating the binding material to bond together the fibres. The binder in the binder areas may be particulate or solid or in the form of partially solid porous masses; it may be deposited by printing a resin in melt form or an adhesive in solution or an aqueous dispersion of a resinous adhesive, or by depositing dry binder particles in spaced areas and then fusing them under controlled conditions of temperature and pressure. The fibrous layer itself may be formed by carding, gametting, air-laying or paper-making methods. Individual layers formed by one or more of these techniques may be laminated to provide a thicker layer for conversion into the fabric of the invention. Specification 804,852 is referred to.

Title: Electric clocks
IPC: G04C21/08
Filed: 1932-01-16
Abstract: 387,108. Electric clocks. ENGLISH CLOCK & WATCH MANUFACTURERS, Ltd. and WALFORD, H. N., 11, Holyhead Road, Coventry. Jan. 16, 1932, No. 1347. [Class 139.] Striking-mechanism. - In a clock driven directly by a synchronous motor, the striking- mechanism is driven at the appropriate times by being moved into gear with the main driving mechanism. The motor comprises the usual stator and notched rotor, the latter driving the hands through suitable gearing and also rotating a wheel continuously. The striking gear comprises the hour snail 9 coacting with the rack 6, 11 normally held in the raised position shown by a pin 8 mounted on a rack hook z. The latter is pivoted at P and carries further pins 2, 7. The pin 7 normally locks the pallet disc 4 mounted on a shaft q, while the pin 2 engages the extension 3 of an arm t pivoted at q and carrying a wheel s meshing with a wheel r mounted on shaft q. The half-hour cam v coacts with a pivoted lever w which engages the extension x of the hook z. A pin 14 on the arm 3 engages the periphery of a cam 12 pivoted to the casing at 121 and carrying a pin 13 engaging in a slot in the lever w. The striking hammer l is carried by a shaft m and is operated at each rotation of shaft q by a cam p on the latter rocking an arm n, rigid with the shaft m and biased by a spring o. In operation, as the half-hour is approached, cam v lifts lever w which rocks the hook z sufficiently for the pin 8 to slip past the bottom or the rack 6 and engage the first tooth thereof, the pin 7 at the same time releasing the disc 4. At the halfhour the lever w, biased by a spring 17, drops ; the cam 12 then allows the pin 14 to drop whereupon the arm t rocks until wheels s and j mesh to drive the shaft q through one revolution during which the hammer operates and the gathering pallet 5 on the disc 4 lifts the rack whereupon the spring y rocks the hook z clockwise ; the pin 8 moves to its normal position as the pin 2 rocks the gear s out of mesh and pin 7 locks the disc 4. At the hour, the larger projection on cam v causes an increased movement of the hook z so that the pin 8 moves to free the rack 6 which falls until a projection 10 thereon engages the hour snail 9. The subsequent operation is as before, the number of revolutions of shaft q however depending on the number of rack teeth to be gathered by the pin 5. The angular movement of the arm t is limited by a projection 15 thereon engaging in a hole 16 in the frame.
