Abstract: 397,689. Drinking-appliances for animals. NEWLANDS, J., Mid Dalziel, Dalcross, Inverness. Oct. 7, 1932, No. 27906. [Class 5 (ii).] The bowl 5 of aluminium or aluminium alloy or other light metal is secured by a pivot pin 7 to a lug 9 at the lower end of a water delivery nozzle 6. The nozzle 6 is preferably integral with a valve casing 10 enclosing a single valve 11 carried at the upper end of a spindle 12 extending through the casing into contact with an adjustable stop 14 in a rearward extension of the bowl 5. A spring 15 normally holds the valve on its seat 16 and an adjustable stop 18 is adapted to engage a tail 17 extending upwardly to limit its lift. The valve casing 10 may be attached in an ordinary way to a water supply pipe or, as shown, may be integral with a water connection having a wall plate 21 attached to or integral with it. A stop 22 is provided to prevent the bowl 5 being tilted upwardly too far. In operation, on the bowl being depressed, the valve is lifted permitting water to flow into the bowl: the spring 15, acting through the valve stem 12 and the stop 14 on the bowl, returns it to its original position when the depressing pressure is removed.

Clutches, friction. -Asbestos compound or other friction material is applied to clutch or brake discs in the form of segments or studs cast or forced into apertures formed in the disc, the anea of the friction material at a given radius being in accordance with the wearing effect at that radius. As shown in Fig. 1, segments of friction material are attached to both sides of the disc by casting, pressure, and heat treatment, the material extending through holes or notches 20, 25 in the disc. The straight edges of the segments form a more open angle than the radii of the disc whereby the area of the friction material at a given distance from the centre of the disc is in accordance with the wear at that distance taking into account the speed at that distance. The discs may be cut out as at 19 to compensate for inequalities in the metal of which the disc is made. Figs. 6 and 7 show a disc provided with studs 26, 26a, 26<b> of friction material, the number or area of which at a given distance from the centre is in accordance with the wear at that distance.

In a further form, studs or segments are attached in the manner described to segmental cores of sheet metal riveted to a central frame to form a complete disc.
Patent GB-427036-A (GB)
Title: Improvements in the manufacture and production of vinyl ethers
IPC: C07C43/16
Filed: 1933-10-16
Abstract: Vinyl ethers are manufactured by causing acetylene to act in the gaseous phase on a volatile organic compound containing one free alcoholic hydroxyl group in the presence of a non-volatile catalyst having a strongly alkaline action.  Suitable catalysts are alkali metal oxides, hydroxides and cyanides, e.g. those of sodium, potassium, lithium, rubidium and caesium, alkali metal zincates and the alcoholates, phenolates and naphtholates of the alkali metals. The corresponding alkaline earth metal compounds are usually not sufficiently active, but the oxides may be employed as carriers for the catalysts, e.g. soda lime may be used as the catalyst.  Other carriers may be used, especially those having a large surface, e.g. active carbon.  Suitable alcoholic compounds are volatile monohydric aliphatic and cyclic (hydroaromatic and aliphatic-aromatic) alcohols and volatile partially etherified or esterified polyhydric alcohols, e.g. methanol, ethanol, n- and isopropanol, butanols, hexanols, octanol, decanol, benzyl alcohol, 1-phenyl-3-propanol, cyclohexanol, the monomethyl, -ethyl, -butyl and -phenyl ethers of glycols and the dialkyl ethers of glycerol, also aminoalcohols, e.g. ethanol- or propanolamine or monoalkyl alkylolamines, e.g. N-methylethanolamine or N-cyclohexylethanolamine.  The reaction may be carried out at 150--350 DEG  C., preferably at 250--300 DEG  C. The acetylene may be diluted with inert gases, e.g. nitrogen. Increased pressure may be employed in the case of alcohols of very low boiling point, e.g. methanol.  In an example, a mixture of n-butanol vapour and acetylene is passed over soda lime at 265 DEG  C. to produce vinyl n-butyl ether.  The soda lime may be replaced by carbon impregnated with potassium hydroxide or sodium zincate.  In a similar manner vinyl methyl, n-propyl, isopropyl, amyl, cyclohexyl and benzyl ethers may be obtained from the appropriate alcohols.  Specification 182,112, [Class 2 (iii)], is referred to.
