Title: Improvements in or relating to sound-record duplicating devices
IPC: G11B7/28
Filed: 1925-11-20
Abstract: 243,375. Roux, B. Nov. 21, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Records, duplicating; optical apparatus; electric sound-boxes; electric circuit applications.- Relates to apparatus for reproducing one record from another whereby the reproduced record may be of different size or type and have different characteristics, for example a zigzag, hill-anddale or photographic record may be reproduced in any of these forms and any undesired characteristics may be suppressed. As shown, an original record C of hill-and-dale type actuates a stylus S<1> to cause a flunctuating current, corresponding to the record, in a coil E. This current operates through a transformer t<1>, is amplified by one or more thermionic valves R and passes through transformer t<2> and one or more filters F<1>, F<2> &c. to a coil E<2> on a permanent magnet A<2> actuating a stylus S<2> to cut a zigzag type of record on a disc D<2>. A telephone T connected in series, shunt or inductively in the circuit of the coil E<2> enables the supervisor to adjust the filters and valves to modify the characteristics as desired so that undesired harmonics may be suppressed. The filters may be arranged in front of the valves ; and the reproducer shown may be replaced by a microphone of the granulated carbon or condenser type. Arrangements are described and illustrated in which the original or duplicated record is a photographic record.

A limit switch comprises a bridging contact plate 4 loosely carried by a plunger 3 which has a slidable sleeve 10 arranged to act on the plate 4 through a spring 8 if the contacts stick in the normal position shown. Depression of the plunger normally causes compression of a return spring 7 so that spring 8 can expand and move contact 4 to engage contacts 5a. If the contacts stick, plunger 3 at first moves relatively to the sleeve 10 which is then operated by the actuating means so as to cause spring 8 to become solid and separate the contacts. The fixed contacts 5, 5a are carried by L-shaped members 11 as in Specification 731,050. Several switches may be arranged in endwise disposition in a box with the outward end of the plunger of one switch in a recess 40a in the next switch so that all switches are operated in sequence (Fig. 5, not shown).

Abstract: A thickened lubricating oil composition, particularly a lubricating grease, comprises a lubricating oil, sufficient inorganic gel to thicken the oil and minor proportions of a cationic surface-active agent and a water-soluble inorganic nitrite.  The lubricating oil may be a mineral or synthetic lubricating oil or mixtures thereof. Specific synthetic lubricating oils mentioned are oxyalkylene polymers (e.g. propylene oxide polymers, ethylene oxide-propylene oxide copolymers, trimethylene glycol polymers and ethylene glycol-trimethylene glycol polymers), silicone fluids, organic phosphates (e.g. tricresyl, trioctyl, diphenylcresyl or diphenyloctyl phosphate), polymerized olefins, polyvinyl caprylate, octyl caprylate and esters of dicarboxylic acids (e.g. di (2-ethylhexyl) sebacate and di (3-methylhepty) adipate.  The inorganic gel may be silica, alumina, magnesia, the oxides of calcium, copper, barium and strontium and mixtures thereof, synthetic zeolites, saponite, hectorite, montmorillonite, bentonite, mixed silicate-silica gels and mixed silicate-hydroxide gels.  The inorganic gel may be an aerogel and the inorganic gel may be first treated with the cationic surface-active agent, where this is a quaternary ammonium salt.  Thus bentonite may be treated with dimethyldicetyl-ammonium chloride to form the aliphatic ammonium bentonite complex.  Nitrates mentioned are those of ammonium, sodium, potassium, lithium, barium, calcium, magnesium, copper, iron, lead, aluminium and zinc.  The cationic surface-active agents are discussed under the following headings:-(a) quaternary ammonium salts, (b) amine salts of organic or inorganic acids and (c) miscellaneous organic nitrogen compounds such as oleic acid salt of 2-heptadecylimidazoline, acrolein ammonia condensation products, diallylamine-H2S condensation products and partial fatty acid amides of epichlorhydrin-ammonia condensation products.

Title: Improvements in and relating to processes for manufacturing substances having wetting, washing, emulsifying and like properties, and the products obtained thereby
IPC: C07F5/04
Filed: 1933-10-27
Abstract: Sulphonated boric acid esters of alcohols having at least eight carbon atoms, which may be used in the textile and leather industries as wetting, emulsifying, frothing, washing and permeating agents are prepared by heating the alcohols with boric acid to a temperature above 100 DEG  C. while removing the liberated water by distillation and sulphonating the resulting esters with oleum, concentrated sulphuric acid or other water free sulphonating agent.  Any unesterified alcohol is removed before the sulphonation is effected. In an example, sperm oil alcohols are esterified with boric acid by heating in vacuo and oleum is used for the sulphonation.  With unsaturated alcohols the sulphonation may be stopped when sulphuric esters are obtained or the sulphonation may be continued so as to produce true sulphonic acids.  The Specification as open to inspection under Sect. 91 comprises also additional examples in which cetyl alcohol, cholesterin-free wool fat alcohols, monochlorhexadecyl alcohol and olein alcohol are first esterified with boric acid to give the esters of meta or ortho boric acid, and are then sulphonated.  Solubility may be improved by passing chlorine into the sulphonation mixture.  The products may be used alone or mixed with waxes, fats, oils, cholesterin substances or fatty acid amides for removing the shine of artificial fabrics especially viscose.  The use of the products in the paper and cosmetic industries, for the manufacture of spinning lubricants and as hair washes or bath salts is mentioned.  This subject-matter does not appear in the Specification as accepted.ALSO:Sulphonated boric acid esters of alcohols having at least eight carbon atoms in the molecule are stated to be emulsifying and dispersing agents.  The sulphuric esters obtained by sulphonating boric acid esters of the unsaturated higher alcohols form milky, stable emulsions with water.  A sulphonated product derived from sperm oil alcohols and boric acid is mentioned. The Specification as open to inspection under Sect. 91 comprises also the use of the products for emulsifying fats, waxes and resins, and the manufacture of spinning lubricants.  Products derived from cetyl and olein alcohol, monochlorhexadecyl alcohol and cholesterin-free wool fat alcohols are mentioned.  This subject-matter does not appear in the Specification as accepted.
