IPC: H04N9/45
Filed: 1966-08-25
Abstract: 1,187,387. Colour television. MARCONI CO. Ltd. 25 May, 1967 [25 Aug., 1966], No. 38206/66. Heading H4F. Relates to a frequency generating arrangement in a PAL colour television system for producing a predetermined relationship between the colour sub-carrier frequency F sc  and the scanning-line frequency FL, where frequency FSC is of the form FSC = (n Œ “FL Œ ¢KF F , in which FF is the field scanning frequency, K = 2m + 1 and n and m are integers. For example, in the 625 line system with F F  = 50 c/s., n = 284 and K = 1, F sc  = (284 - “) 15625 + 25 = 4433618À75 c/s., i.e. i.e. In a first embodiment, Fig. 1, a source A of the required sub-carrier frequency F sc  is fed as one input to a non-linear detector B the output from which is fed to a band-pass filter C which separates out (F SC  - F<SP>1</SP>), where and to a multiplier-divider chain D of ratio a -. The frequency F 1  appearing at the output b of chain D is applied as the second input to the non-linear detector B. The line frequency FL may be obtained by dividing F 1  by 22. Chain D comprises 10 stages (Fig. 3, not shown), since a = 5<SP>4</SP> Î 2<SP>3</SP> = 5000 and b = 19 x 31 x 101 = 59489. In a second embodiment, Fig. 2, the frequencies F SC  and F 1  are derived from a source AA of frequency F a  = F SC  - F 1 . Frequency F a  is fed directly as one input to a non-linear detector 13 and via a multiplier-divider chain D of ratio (a/b) as the second input. The second   input frequency F 1  = (a/b)-F a  =(a/a+b) F SC  which also equals 22F L . The output from the non- linear detector B is fed to the band-pass filter C which separates out the required colour subcarrier frequency F SC  = F a  + F 1 .

Abstract: 935,895. Heel seat lasting machines. BRITISH UNITED SHOE MACHINERY CO. Ltd. Nov. 25, 1959 [Nov. 26, 1958], No. 38210/58. Class 17 (1). A heel seat lasting machine has a jack-supported last movable between a loading position remote from the lasting and tacking area of the machine and an operative position, a U-shaped heel clamp 2 for clamping the heel end portion of an untacked upper against the last prior to movement to the operative position being mounted on the jack post 4. The heel clamp 2, which has a flexible work-engaging portion, is pivotally secured on trunnions 24 to a pair of levers 12 mounted on a supporting bracket 6 carried by the jack post 4. Pivot pins 16 on either side of the bracket 6 engage in slots in the levers 12 which at their other ends are pivotally connected to a crossbar attached by a rod 22 to a piston in an hydraulic cylinder 10. The piston is hydraulically operated by the depression of a foot treadle (not shown) which controls an hydraulic reversing valve (not shown) connected to the cylinder 10. For the purpose of wiping the marginal portions of the upper inwardly near the breast-line, rockers 40 are mounted one on each side on pivots carried by brackets 44 which are in turn pivotally mounted on the clamp 2. Heel clamp closing arms 48 on the machine have rearwardly extending guide channels 52 into which slidingly fit tongues 36 secured to the sides of the clamp 2 as the jack post 4 is moved to carry the last towards the operative position, thus pressing the sides of the clamp 2 against the last. Simultaneously, the upper surfaces of the arms 48 which are rounded at their forward ends to form cam faces engage the tail portions of the rockers 40 which are thus caused to move inwardly and draw the lasted margins of the upper against the last. The engagement of the tongues 36 with the guide channels 52 ensures the correct positioning of the sides of the clamp 2 while the rear end of the clamp 2 is correctly positioned by the engagement of a conical projection with a corresponding hole suitably positioned in the machine frame. Specifications 473,197 and 510,177 are referred to.

Abstract: The invention comprises chromium and cobalt complex compounds containing one molecule of an azo or azomethine compound and one molecule of a formazane compound both bicyclically bound to one chromium or cobalt atom and mixtures of such Cr or Co complex compounds.  They may be obtained by treating at least one azo or azomethine compound forming bicyclic heavy metal complexes and at least one formazane compound forming bicyclic heavy metal complexes with an agent giving off Cr or Co.  Specified azo compounds are those of the formula <FORM:1046649/C4-C5/1> wherein D represents a radical of the benzene or naphthalene series containing X in a position ortho to the azo bond, E represents the radical of a coupling component coupled in a position ortho to X1, X represents -OH or -COOH or a group which can be converted into such a group, and X1 represents -OH or a primary or secondary amino group.  D and E may contain substituents such as electron-donating or electron-attracting substituents.  Specified azomethine compounds are those of the formula <FORM:1046649/C4-C5/2> wherein D and E1 each represent a radical of the benzene or naphthalene series containing X11 or the hydroxyl group in a position ortho to the azomethine bond, and X11 represents -COOH or -OH.  The azomethine dyes can contain substituents. Specified formazane compounds are those of the formula <FORM:1046649/C4-C5/3> wherein A and B each represent the radical of the benzene or naphthalene series wherein A contains the substituent X111 in a position ortho to the azo bond, R represents an alkyl or alkenyl radical which may contain non-ionogenic substituents, a cycloalkyl group, a carbocyclic radical, an unsaturated heterocyclic radical, and X111 represents a metallizable group, e.g. -OH or -COOH. The rings A and B may contain substituents.  Suitable agents giving off chromium and cobalt are chromic fluoride, acetate, formate or sulphate or potassium or ammonium chromic sulphate; and cobalt acetate, formate or sulphate.  The reaction of azo, azomethine and formazane dyes with agents giving off cobalt is preferably performed simultaneously whereas the reaction with agents giving off chromium is preferably performed in steps.  Mixtures of metal-containing mixed complex compounds can be obtained by treating two or more of the mixtures of dyestuff reactants of Formulae I, II and III with suitable proportions of agents giving off Cr or Co.  The dyestuffs may be used for dyeing plastics, lacquers, varnishes or spinning masses obtained from acetyl cellulose or polyamides.  Azomethine compounds are obtained by condensing an o-aminophenol or o-aminonaphthol or o-aminobenzoic acid compound with an o-hydroxyaldehyde of the benzene or naphthalene series.  Formazanes used in the above processes are obtained by coupling the appropriate diazotized substituted benzene with the appropriate aldehyde phenylhydrazone.
