Title: Colour television receiver
IPC: H04N11/16
Filed: 1972-03-10
Abstract: 1345295 Colour television GENERAL CORP 10 March 1972 [18 March 1971] 11187/72 Heading H4F A demodulating circuit for a PAL colour television signal operates to reduce relative phase errors between the reference subcarriers by altering the phase of one of the reference subcarriers if the reference subcarriers are not in quadrature. A B-Y oscillator 6 and an offset R-Y oscillator 8 are provided, phase modulator 9 being fed with a phase correcting voltage from the junction of resistors 17, 18 and a saw-tooth voltage from 10. The signal from 9 is passed to demodulators 13, 14 to which are also fed signals from B-Y oscillator 6 via +45 degrees phase shifter 11 and - 45 degrees phase shifter 12. If the signals from 6 and 9 are in quadrature the outputs from 13 and 14 are square waves of equal amplitude and opposite phase, which run to zero, but if the signals from 6 and 9 are not in quadrature the outputs from 13 and 14 are not equal in amplitude and their sum is passed via an integrator to 9. Alternatively the correction signal may control the signal passed from the input to oscillator 8. In an alternative embodiment (Fig. 5, not shown) the signal from 9 is demodulated using two demodulators operating in antiphase fed by a signal from 6 via a 90 degrees phase shifter, the signal from 9 also being demodulated using the signal from 6 directly, the three resulting outputs being matrixed before being passed as the correction signal to 9.

The heating is preferably continued until the product has an acid value below 50, the proportions of reagents being such that the hydroxy value is then 50-250.  The preferred major acid component is phthalic acid with a -substituted alkanoic acids, e.g. 2-methylnonanoic acid, or benzoic acid as monocarboxylic acids; suitable minor acid components (i.e. those limited to 30 wt. per cent) are castor, dehydrated castor, perilla, coconut, cottonseed, train, soybean and tall oil fatty acids, stearin, succinic, adipic, maleic, acrylic, isophthalic and trimellitic acids.  Suitable polyols are ethylene-, diethylene-, propylene- and polypropylene-glycols, butane-1:4-, pentane-1:5-, butene-1:3- and 2-methylpentane-2:4-diols, glycerol, hexane-1:2:6-triol, trimethylol propane, trimethylolethane and pentaerythritol dipentaerythritol and sorbitol.  Monohydric alcohols that may be used include amyl, cyclohexyl, decyl, lauryl and stearyl alcohols and oxo or natural oil alcohols.

In examples polyesters are prepared from phthalic anhydride and a mixture of trimethylolpropane and hexane-1:2:6-triol or of pentaerythritol and ethylene glycol, and isodecyl alcohol or a synthetic mixture of alcohols.  They are mixed with a methylated or butylated methylol melamine resin, rutile TiO2 and a xylene/n-butanol mixture, to give a varnish.ALSO:Tinplate or steel is coated with a varnish comprising a volatile organic solvent, an aminoplast resin, and a polyester derived from a benzene-o-dicarboxylic acid, a mono hydric alcohol of 5 or more C atoms, and a mixture of polyols (see Division C3).

Patent GB-606665-A (GB)
Title: Improvements in or relating to the preparation of ditertiary diamines derived from aniline
Filed: 1945-05-07
Abstract: Ditertiary diamines of the general formula <FORM:0606665/IV(b)/1> (wherein R represents an alkyl group of at least 2 carbon atoms or an aralkyl group, and the benzene ring may be substituted by one or more alkyl groups) are manufactured by condensing dimethylamine in the presence of a reducing agent (e.g. zinc and acid, formic acid or hydrogen in the presence of a hydrogenation catalyst) with an aldehyde of the general formula <FORM:0606665/IV(b)/2> (wherein R is as above defined and the benzene ring may be substituted by one or more alkyl groups).  In examples: (1) N-phenyl-N-benzyl-2-aminoacetaldehyde diethyl acetal is hydrolysed with aqueous hydrochloric acid in the cold, the product is neutralized with sodium bicarbonate and extracted with ether, the ether is distilled off and the aldehyde obtained is dissolved in alcohol and treated in an autoclave with dimethylamine and hydrogen in the presence of Raney nickel, producing N-benzyl-N-dimethylaminoethylaniline; (2) N-phenyl-N-ethyl-2-aminoacetaldehyde (prepared similarly from its acetal, except that the hydrolysis is effected at 45 DEG  C. and the neutralization with caustic soda) similarly yields N-ethyl-N-dimethylaminoethylaniline.  Specification 604,675 is referred to.  N - Phenyl - N - benzyl- and -ethyl-2-aminoacetaldehyde diethyl acetals are obtainable by condensing chloroacetal with benzylaniline and ethylaniline respectively, in the form of their sodio derivatives made by treating the bases with sodamide.  The Specification as open to inspection under Sect. 91 comprises also the use of acetals in place of the aldehydes in the condensation, and the manufacture of other similar diamines in which the alkylene chain in of the form -(CR1R2)n-1CH2-, where R1 and R2 represent hydrogen atoms or alkyl groups and n is an integer equal to or greater than 2.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in emergency governors
IPC: G05D13/00
Filed: 1922-04-27
Abstract: 179,922. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Davis, D. C.). May 10, 1921, [Convention date]. Stop-gear; automatic gear. - An emergency governing device comprises a vibratory member adapted, when the governed unit attains a certain excessive speed, to vibrate in unison with the motor unit and thereby through certain agencies to effect the governing of the unit. Fig. 1 shows one application of this principle comprising a hollow reed 13 attached to a portion 14 of the motor unit driving a rotating shaft 10 and having a throttle valve 24 to the spindle 23 of which is attached a piston 21 pressed downwards by a spring 22 and upwards by oil supplied under pressure from the pipe 18 in communication with the hollow interior of the reed closed at the lower end by the spring-controlled cap 12. When the motor unit attains a speed of periodicity equal to that of the reed, the latter is caused to vibrate in unison until, when the amplitude is sufficiently large, the cap 12 is struck and opened by projections 11 on the shaft, thus releasing the oil pressure and permitting the piston 21 to reduce or close the throttle. A weight 16 adjustable along the reed permits variation of the natural period of the latter. In the event of the vibration of the member 14 being small and ineffective, the reed can be vibrated by puffs of fluid emitted from an opening in a housing surrounding the shaft in which a blade is made to rotate. Fig. 5 shows a modification in which the reed 13 is directly attached to a piston valve 30 controlling release of the oil, which valve is operated by the projections 11 engaging the vibrating end of the reed, a dash-pot 35 and a spring 34 serving to restore the valve slowly to its original position. To avoid possible damage to the reed it can be replaced by a rigid member and mounted to control, through a flexible connection, operation of the member by the projections.
