Title: Improvements relating to television transmitters and receivers or the like
IPC: H04N7/084
Filed: 1947-01-27
Abstract: 624,740. Diplex pulse signalling; pulse modulation. STILLWELL, P. F. T. C. Jan. 27, 1947, No. 2417. [Class 40 (v)] In a modulated pulse transmission system, audio signals are divided into a band below half the pulse repetition frequency, and a band above that frequency which is mixed with local oscillations to produce a second band of frequencies below half the pulse repetition frequency, both resulting bands being transmitted separately. As applied to a 605-line television system in which the synchronizing pulses are modulated by the audio signals, said signals are passed to both a 0-6 kc/s. filter 8, Fig. 2, and a 6-10 kc/s. filter 9. The output of filter 8 modulates the width of the synchronizing pulses. The output of filter 9 modulates the output of an 11 kc/s. oscillator 12, the resultant lower sideband being selected by the filter 13 and used to width modulate further pulses arranged to follow the synchronizing pulses during the blanking interval. Alternatively, the synchronizing pulses may be modulated both in width and amplitude to carry both parts of the audio signal. At the receiver, Fig. 3, the two sets of pulses are separated by gating, the synchronizing pulses are demodulated by a filter 14, whilst the further pulses are demodulated by a filter 16 before being mixed with 11 kc/s. oscillations from an oscillator 18, the lower sideband being passed by filter 19 and added to the other band of signals. For a low fidelity receiver only the 0-6 kc/s. band of signals need be demodulated. Specification 613,857 is referred to.

Title: Improvements in and relating to oil burners
IPC: F23D5/14
Filed: 1964-01-21
Abstract: 1,005,553. Vaporization oil burner. G. FUCHS. Jan. 21, 1964 [Jan. 23, 1963], No. 2556/64. Heading F4T. A vaporization oil burner has a blower 7, Fig. 1, supplying air to a combustion chamber 1 through orifices 2, the supply of oil through conduit 18 being regulated in dependence on the air pressure in space 4. The air pressure acts through a pipe 20 on a diaphragm 14 in a regulator 13, Fig. 2, the diaphragm carrying a valve stem 15 with a conical head 16 controlling the flow of oil from inlet 22 to conduit 18. The relative positions of the chamber 1 and regulator 13, and weight of diaphragm etc. are such that valve 16, 17 closes just before oil flows on to floor of chamber 1. When the blower is operated, the diaphragm 14 opens valve 16, 17 with a greater opening for increased air pressure. In Fig. 3, the burner housing 3a has an end cap 11a which is adjustable to vary the gap 12a and hence the inlet orifice for air to blower 7a. Oil is supplied to a pan 23 in the chamber 1a from a regulator 28 having a float 30 controlling a valve 16a biased to the closed position by leaf spring 32. Outflow nozzle 29 is just filled by capillary action. With blower 7a operative, the air pressure builds up, the oil level 27 in regulator 28 drops as does float 30 to open valve 16a producing a corresponding flow through nozzle 29. Should the oil level 27 rise beyond a certain height due for example to leakage past valve 16a, then float spindle 31 closes contacts 33 to operate a valve cutting off the oil inflow. In Fig. 2, a ventilation pipe 19 may be omitted if pipe 18 starts just below diaphragm 14.

Title: Improved polyoxypropylene-polyoxyalkylene surface-active agents
Inventor: LUNSTED LESTER GORDON
IPC: C11D1/44
Filed: 1954-01-28
Abstract: A surface-active agent is made by reacting propylene oxide or a polyoxypropylene glycol with a nitrogen-containing compound containing a plurality of active-hydrogen atoms to produce a polyoxypropylene polymer with a molecular weight of at least 900 and reacting this polymer with ethylene oxide or a polyoxyethylene glycol to produce a polymer containing 20 to 90 per cent by weight of oxyethylene groups.  The nitrogen-containing compound may be (a) ammonia or hydrazine, (b) an organic compound containing at least one hydrogen atom connected to nitrogen (e.g. methylamine, butylamine, amylamine, aniline, ethylhydrazine, phenylhydrazine, N.N-dimethylhydrazine, N.N1-dibutylhydrazine, ethylene diamine, phenylene diamine, hexamethylene diamine, triethylene tetramine, tetraethylene pentamine, imidazimidazoles, pyrazolones, pyrazolidines, hydantoins, amides, imines or guanidines) or (c) a condensate of ammonia or an alkyl amine with an alkylene oxide (e.g. tri-2-propanolamine, N - butyl - di - 2 - propanolamine or triethanolamine).  The reaction between propylene oxide and the nitrogen-containing compound may be effected in presence of an acid catalyst or an alkaline catalyst (e.g. sodium hydroxide, a sodium alkoxide or a quaternary ammonium base).  If the nitrogen containing compound is gaseous it may be first dissolved in an organic solvent. Prior to reaction with the ethylene oxide, the polyoxypropylene polymer may be reacted with a difunctional organic compound (e.g. a dibasic acid or a di-isocyanate).  The propylene oxide used may contain up to 10 per cent of ethylene oxide and the ethylene oxide used may contain up to 10 per cent of propylene oxide.  The surface-active agents may be added to fatty acid soaps to prevent scum formation (see Group III). Specification 731,603 is referred to.ALSO:In order to prevent the formation of insoluble salts when a fatty acid soap is used in hard water, there is added to the soap 4-25 per cent by weight of a non-ionic surface-active agent which is made by reacting propylene oxide or a polyoxypropylene glycol with a nitrogen-containing compound to produce a polyoxypropylene polymer with a molecular weight of at least 900 and reacting this polymer with ethylene oxide or a polyoxyethylene glycol.  In an example the surface-active agent is added to a soap composition comprising 60 per cent medium titer soap, 30 per cent builders (phosphates, silicates and soda ash) and 10 per cent moisture.  Specification 731,603 [Group IV(a)] is referred to.

Title: Fatty acyl derivatives of amino acids
IPC: A01N37/46
Filed: 1952-01-31
Abstract: Fatty acid amides of aliphatic amino carboxylic acids are prepared by condensing a higher fatty acid halide with a salt of a lower aliphatic amino carboxylic acid having a free amino group with a hydrogen atom directly attached to the nitrogen atom, in an aqueous medium at a pH between 9 and 12.5 and in the presence of an acceptor for the hydrogen halide liberated, thereby forming an amide of the amino acid salt, and acidifying to a pH of not more than 4.5, preferably between 2 and 4, and recovering the resulting free acylated amino acid.  The term "higher" is used to mean that the radical has at least 8 carbon atoms and "lower" to mean having up to 6 carbon atoms.  The amino carboxylic acid salt is preferably used in excess in the condensation.  Temperatures up to the refluxing temperature of the mixture may be used.  An inert solvent such as a hydrocarbon or halogenated hydrocarbon, e.g. ethylene dichloride may be present.  Specified acid acceptors which may be added before or during the condensation include sodium, potassium and lithium hydroxides and carbonates, sodium bicarbonate, magnesium and calcium hydroxides, amines having no replaceable hydrogen atoms, e.g. pyridine or trimethylamine and excess of the amino acid.  Any alkalizing agent may be used to establish the required pH, and may be the same as the acid acceptor; examples include sodium metal, sodium hydride, sodium hydroxide-carbonate mix and barium hydroxide.  The acidification may be effected with sulphuric or hydrochloric acid preferably after a heat treatment at 50 DEG -100 DEG C. which prevents foaming in later working up.  The free acylated amino acid may be isolated by extracting with an organic solvent, e.g. ethyl ether or by heating the acidified mixture whereupon the acylated amino acid separates out as an oily layer on the aqueous phase.  The product may be converted into salts by means of, for example, alkali and alkaline earth bases and ammonium hydroxide.  The products have use as wetting, dispersing and textile-treating agents.  Examples describe the production of lauroyl sarcosine, myristoyl glycine and palmitoyl sarcosine from the fatty acid chloride and sodium or potassium salt of the amino acid.  Other reactants mentioned are the salts of alanine, valine and leucine and the chlorides or bromides of caprylic, stearic, oleic and linoleic acids and mixtures of such acids as occur in coconut, palm kernel, palm, olive, and cotton seed oils, tallow and hydrogenated derivatives thereof; the acids in general have 8-24 carbon atoms, preferably 12-18.

Title: Gasoline fuels for internal combustion engines
IPC: C07C51/567
Filed: 1960-01-26
Abstract: Alkenyl succinamic acids, having 10-25 carbon atoms in the alkenyl radical, and suitable for use in gasoline compositions (see Group III), may be prepared by reacting the appropriate alkenyl succinic acid anhydride in a 1 : 1 molar ratio with ammonia or with ammonium hydroxide.  Thus, ammonia gas may be bubbled through a solution of the anhydride in a hydrocarbon solvent, such as benzene, toluene or xylene, preferably at about 60-80 DEG C.  Alternatively, ammonium hydroxide solution may be added to the anhydride (preferably in the presence of an organic solvent such as petroleum ether, benzene xylene or toluene) at about 5-30 DEG C., and the ammonium succinamate thus formed may be converted to the free acid by the addition of a dilute aqueous acid such as hydrochloric or sulphuric acid.  In Examples, (1) tetrapropenyl succinamic acid is formed by reaction between ammonium hydroxide and tetrapropenyl succinic anhydride, with subsequent addition of hydrochloric acid and (2) 11-tricosenyl succinamic acid is formed by reaction between ammonia gas and 11-tricosenyl succinic anhydride.ALSO:The formation of ice in the carburetter of an internal combustion engine is inhibited by adding to the gasoline fuel a small amount of an alkenyl succinamic acid having 10-25 carbon atoms in its alkenyl radicle.  The gasoline fuel may also contain anti-knock agents, pre-ignition inhibitors, anti-rust agents, metal deactivators, dyes, antioxidants, detergents and solvent oils.  Examples of solvent oils are mineral oils, diester oils, polyalkylene glycols, silicones, phosphate esters, polypropylenes and polybutylenes.  In examples, 0.01, 0.02 or 0.05% by weight of tetrapropenyl succinomic acid is added to a gasoline composition consisting of catalytically cracked gasoline, natural gasoline, benzene, toluene and butane.
