Abstract: 533,155. Wetting &c. agents. SOC. OF CHEMICAL INDUSTRY IN BASLE. Aug. 2, 1939, Nos. 22399 and 22400. Convention dates, Aug. 13, 1938 and July 21, 1939. Samples furnished. [Classes 2 (iii) and 15 (ii)] [Also in Group III] Cyclic amidines are condensed with N- methylolcarboxylicamides in the presence of acids, to give products useful in the textile, leather and paper industries. The starting materials may contain a group which causes or increases the water solubility of the product namely a sulphonic, thiosulphuric ester, sulphuric ester or quaternary ammonium group, a polyglycol residue or an amino or imino group in salt form. Alternatively a halogen atom may be present, and may be converted into a neutralized sulphonic or thiosulphuric ester group or into an amino or imino group in salt form or a quaternary ammonium group. Also a hydroxy group may be converted into a sulphuric ester group or etherified with ethyleneoxide to introduce a polyglycol residue. The soluble products have wetting, washing, emulsifying, foaming, levelling and softening properties when they contain an aliphatic or cycloaliphatic radicle of high molecular weight. The products may be used alone or in association with sodium acetate, solvents, soaps, colloids and loading, softening and wetting agents. In examples : (1) Á- heptadecylbenzimidazol is condensed with methylolchloracetamide and pyridine or with the addition compound of methylolchloracetamide and trimethylamine : (2) Á-heptadecylbenzimidazol and N-methyl-Á-heptadecylbenzimidazol hydrochloride are condensed with sodium methylolacetamidesulphonate: (3) Á- heptadecylimidazoline is condensed with sodium methylolacetamidesulphonate and with the addition product of methylolchloracetamide and trimethylamine. Glacialacetic acid and sulphuric acid are used as acid condensing agents. α-Methylglyoxaline, Á-methyl-, butyl,- and heptadecenyl-benzimidazol, benzimidazol-Á- methylenebenzylether, benzimidazol-Á-methyleneamylthioether, Á-naphthenylbenzimidazol, Á-undecyl-1:2-naphthimidazol and Á-undecylperimidine are specified starting materials, and also methylolcompounds of aliphatic, aromatic, aliphatic-aromatic, cycloaliphatic and heterocyclic amides, urethanes, urea and melamine. The following acids from which starting materials may be derived are mentioned: acetic, acrylic, caprylic, capric, myristic, benzoic, naphthoic, hexahydrobenzoic, resin, naphthenic, chlormethylbenzoic, chlorpropionic and salicyclic acid. The methylol compounds are prepared by treating with formaldehyde the acid amides in the presence of basic or acid catalysts such as trimethylamine, potassium carbonate, barium hydroxide, hydrogen chloride, sulphuric acid or zinc chloride. The reaction with the cyclic amidine may be effected in the presence of a solvent such as methanol, dioxane, acetone, benzene, toluene or pyridine. Samples have been furnished under Sect. 2 (5) of products obtained by condensing Á- heptadecylbenzimidazole with methylolbenzamide, phenylacetic acid methylolamide and also with nicotinic acid methylolamide. Specification 460,858 is referred to.

Title: Discharge lamp supply arrangement
IPC: H05B41/18
Filed: 1971-11-18
Abstract: 1331821 Discharge lamp supply PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Nov 1971 [21 Nov 1970] 53604/71 Heading H2H A starting and operating circuit for a discharge lamp 7 which may be a low pressure mercury vapour lamp having preheated electrodes 8, 9 comprises a capacitor 4 and an inductance 3 in series with the lamp and with a branch comprising a diode 5 and a resistor 6 having a positive temperature characteristic. The lamp is further shunted by a glow discharge switch 10 and in operation, after the first half cycle of a supply connected at 1, 2, capacitor 4 is charged to double the peak input voltage which causes the glow at 10 to ignite. At this time the current in the branch 5, 6 is small and merely balances the discharging effect of the glow discharge. Heat produced by this discharge causes bimetal electrodes 11, 12 in the switch 10 to close together and produce a preheating current through the electrodes. The discharge is terminated upon switch closure and the electrodes cool and come apart, whereupon a pulse of high voltage inites the lamp. The increased current through the lamp and diode branch after ignition causes the resistance to heat up and attach a value such that its resistance is large to effectively render the diode branch inoperative. In a modification, two or more lamps each shunted by a glow switch are employed in series. Component values are chosen such that the resistance 6 prior to lamp ignition has a value not exceeding twice that of the operating value of the lamp, and about 20 times this resistance after lamp ignition. The ignition voltage of the discharge switch should be more than 90% of the supply R.M.S. voltage.

Abstract: 1443223 Valves APPLICATION DES GAZ 26 Nov 1973 [24 Nov 1972] 54794/73 Heading F2V [Also in Division F4] Gas burning apparatus comprises a burner 2 and a pipe 8 connected to the burner and to a container 1 for gas or liquefied gas under pressure, a pressure-reducing valve 3 in the pipe comprising a valve closure 5 open to the upstream side of the valve, and a diaphragm 4 open to the downstream side, and biased to the valve-open position, movement of the closure being controlled by the diaphragm, the ratio of the effective surface areas of the closure and diaphragm being arranged so that if the pressure in the container exceeds a predetermined value, the rate of gas flow to the burner is significantly decreased. In operation, if container 1 is heated by, e.g. burner 2, the liquefied gas pressure increases upstream of valve 3 which latter reduces the downstream pressure of gas being supplied to the burner. In extreme conditions the gas pressure may be insufficient to maintain a flame at the burner. The burner and gas container are incorporated in a portable stove Fig. 1. A vapourizing loop 8a or 8b may be provided in pipe 8, this loop being heated by the burner. To provide for an additional manual control of the burner, a rotatable control button 13 having a helical cam path 16, 16a which coacts with pegs 17, 17a is provided. This button is used to vary the tension in a spring 14 which varies the pressure applied by the diaphragm on the closure member 5.

Abstract: 1396434 Hoses; making GOODYEAR TIRE & RUBBER CO 1 Dec 1972 [22 Dec 1971] 55517/72 Headings F2P and F2G A process of making a hose assembly comprising a hose having therewithin a previously wound helical coil of stiff resilient metal wire, includes the steps of gripping only a portion of a single turn of said coil, then engaging respective surfaces of said hose and of said coil in frictional contact and rotating either the hose or the coil relative to the other while pulling the coil longitudinally into the hose so as to elastically reduce the diameter of the coil one turn at a time relative to the inside diameter of the hose and then releasing said portion of the coil after the coil is in place in the hose. As shown apparatus 100 for making such a hose assembly comprises a flexible shaft 102 having at the outer unsupported end 104 a head 112 for releasable gripping therein one end of a coil W the other end of the shaft being connected to a collet 128 by means of which it can be rotated, e.g. manually. In use the hose 100 previously placed about the shaft is moved manually toward the head 112 to engage the coil whilst the shaft 102 is rotated. As each successive turn of the coil W comes in to engagement with the inner surface of the hose 100 its diameter is reduced so that the coil can be moved longitudinally into axial registry with the hose. After the coil is within the hose it is released from the head 112 so that it expands into engagement with the hose. Alternatively the coil W can be placed about the shaft and the hose fed on to it in a manner similar to the above. The hose can be in the form of a bend and/or of corrugated form (Fig. 3, not shown) and can be of rubber or rubber like material in a cured or uncured state when applied to the coil, in the latter case it is subsequently cured with the coil in place. The hose can also have incorporated therein a fabric reinforcement.
