Title: A process for the production of alcohols
IPC: C07C29/149
Filed: 1932-03-17
Abstract: Alcohols are prepared by heating any salt of a fatty acid in a solvent with calcium formate or the salt of another fatty acid and simultaneously reducing the carbonyl compound formed by means of hydrogen under pressure in the presence of a hydrogenating catalyst. The fatty acid salts may be those of barium, strontium, magnesium, the alkali metals, and the heavy metals, e.g. zinc, nickel and copper.  According to the examples, octodecyl alcohol is obtained by forcing hydrogen into an autoclave containing a solution of sodium stearate and calcium formate in water or cyclohexane to which copper carbonate precipitated on kieselguhr has been added and maintaining the autoclave at an elevated temperature for some time; similar treatment of a mixture of the calcium salts of acetic acid and the fatty acids of coconut oil yields a mixture of the secondary alcohols C11H21.CHOH.CH3 and C13H25.CHOH.CH3.

Abstract: The invention comprises copper complexes of dyestuffs of formula <FORM:0796397/IV (b)/1> where X may be H or SO3H and R is the residue of an aminonaphthol mono- or di-sulphonic acid with OH o to -N=N-. They may be made by coupling anthranilic acid or a sulpho derivative thereof with an appropriate amino pyrazolone, diazotizing the product and coupling with 2 - ethoxy - 1 - naphthylamine or a sulphonic acid thereof, diazotizing the diazo dyestuff thus obtained and coupling with the requisite aminonaphthol sulphonic acid and coppering the product by a known method.  The dyestuffs dye vegetable fibres in green shades.  In examples, copper complexes of the following dyestuffs are made (1) 2-amino-4- or -5-sulphobenzoic acid --> 1-(41-aminophenyl)-3-methyl-5 - pyrazolone --> 2 - ethoxy - 1 - naphthylamine - 6 - sulphonic acid --> 2 - (phenylamino-) or -(31 - sulpho- or -carboxyphenylamino) - 5 - naphthol - 7 - sulphonic acid; (2) anthranilic acid --> 1-(41-aminophenyl)-3-methyl - 5 - pyrazolone --> 2 - ethoxy - 1 - naphthylamine 6-sulphonic acid --> 1-amino-8-naphthol-2,4-disulphonic acid; (3) anthranilic acid --> 1 - (41 - amino - 31 - sulphophenyl) - 3-methyl - 5 - pyrazolone --> 2 - ethoxy - 1-naphthylamine 6-sulphonic acid --> 2-(31-carboxyphenylamino) - 5 - naphthol - 7 - sulphonic acid and (4) 2-amino-5-sulphobenzoic acid --> 1 - (41 - aminophenyl) - 3 - methyl - 5 - pyrazolone --> 2 - ethoxy - 1 - naphthylamine --> 1 - amino - 8 - naphthol - 2,4 - disulphonic acid and the products used to dye cotton.

Title: Aluminium chloride catalyzed reaction of chloretone
IPC: C07C17/26
Filed: 1953-03-24
Abstract: Aryl-dichloro-methylpropenes of the general formula <FORM:0724818/IV (b)/1> where R is a chlorine, bromine or hydrogen atom or an alkyl or alkoxy radical of 1-4 carbon atoms are prepared by reacting chloretone with a benzenoid compound of the formula <FORM:0724818/IV (b)/2> in the presence of anhydrous aluminium chloride.  Suitably the reaction is carried out at 60-150 DEG C., preferably in the range 80-125 DEG  C. using 0.25 to 0.75 mole of aluminium chloride per mole of chloretone.  The reaction products may be separated by adding the reaction mixture to a mixture of crushed ice and strong mineral acid, separating the oily organic layer, extracting the aqueous layer with ether, combining the ether extracts with the organic layer, evaporating to remove the ether, and separating the products by fractional distillation under reduced pressure.  The reaction mixture contains a -chloroisobutyric acid formed as a by-product, which is also separated by fractional distillation. In examples there are prepared (1) 3 - (4 - chlorophenyl) - 1 : 1 - dichloro - 2-methylpropene-1; (2) 3-(4-bromophenyl-1 : 1-dichloro-2-methylpropene-1; (3) 3-phenyl-1 : 1-dichloro-2-methylpropene-1; (4) 3-tolyl-1 : 1-dichloro-2-methylpropene-1 (mixed isomers), and (5) 3-(4-methoxyphenyl)-1 : 1-dichloro-2-methylpropene-1.

Title: Improvements in fire and other alarm systems
IPC: G08B29/02
Filed: 1951-04-10
Abstract: 698,358. Fire alarm systems. C-O-TWO FIRE EQUIPMENT CO. April 10, 1951 [June 17, 1950]. No. 8327/51. Class 118 (i). [Also in Group XXXVI]. In an electric fire or other alarm system in which a decrease of the current from below a normal level operates a fault alarm, and an increase of the current operates the alarm signal, the detector unit is mounted on a base having terminals which co-operate with contacts in a mounting bracket, so that removal or displacement of the detector unit will operate the fault alarm. Fig. 1 shows an alarm system in which a plurality of detector units are mounted in holders 16. The base connections of the detector unit are such that when inserted in the holder, terminals 45 and 46 are shorted and if rendered operative by the conditions to be detected, terminals 47 and 48 are effectively connected together. When the detectors are in position, a normal current from source 12 flows through relay 15, resistance 104, through the shorted connections in the detector, to earth. This normal current through relay 15 is sufficient to maintain its movable contacts in the non-operative intermediate position. Should the current rise, due to a detector operating and effectively shunting out resistance 104, contacts 39 and 91 are operated, which respectively energize zone indicator lamps 87 and operate alarm relay 95 to operate alarms at a central station or initiate discharge of a fire extinguishing system. Should the current fall, owing to failure of the supply, removal of a detector unit or other circuit interruption, contacts 38 and 97 are operated which respectively operate zone indicator lamps 87 and fault buzzer 100. The detectors and relay 15 and zone indicator 87 shown are associated with a particular locality, and other zones may similarly be protected by providing additional apparatus of a similar type connected to lead wires 105. Fig. 2 shows a suitable detector unit of ionization type, in which the electrical resistance of a standard body of air in chamber 55 is compared with that of air flowing into a test chamber 56. A small hole 57 is provided to equalize pressure in chamber 55, while a large hole 59 in chamber 56 allows air circulation. Each chamber is subjected to the action of radioactive material 66. Electrodes 70 and 71 are positioned in the chambers, and connected together and to the control electrode of a cold cathode tube 74. If ionized particles are present in the air being tested, due to either flame or smoke the potential of the control electrode is changed causing the cold cathode tube to conduct and so operate the alarm relay 15.

Abstract: 231,523. Kucharski, S. March 29, 1924, [Convention date]. Players for keyboard instruments; actions; tune-sheets; winding-mechanism.-In an apparatus for playing keyboard instruments, depression of an auxiliary key or keys simultaneously advances the tune-sheet step by step and depresses the playing-keys by means of fingers which are drawn under a movable plate by electric means. The tune-sheet apertures and the tracker contacts are arranged in, say, four rows enabling the apparatus to be made narrow. The sheet 8 is of celluloid, paper, &c. about 35 mm. wide, and on contact of a pin 20 with a wire 31 taking place through an aperture, an electromagnet 26 is energized to draw an armature 4, formed as a vertical finger, under a spring-controlled plate 3. Depression of an auxiliary spring-controlled key 2 depresses the plate 3 and thereby also the fingers 4 resting on the playing-keys 5. The plate 3 also carries a lug 12 which, engaging a spring 11 attached to a cranked lever 7, advances the tune-sheet a step by means of grippers 9 engaging in feed holes at the side of the sheet, excess motion of the plate 3, after the grippers engage a stop 17, being taken up by the spring 11. The plate 3 may be divided and the parts placed under the control of different auxiliary keys 2, so that the expression of the melody and accompaniment may be separately controlled. The sheet as it is fed forward is received in a curved spring 32. The fingers 4 may be returned after depression by horizontal springs. The apparatus is provided with positioning-plates which engage between and behind non-playing black keys 5 at the ends of the keyboard. The Specification as open to inspection under Sect. 91 (3) (a) states that mechanical means, consisting of falling levers directly connected to the fingers 4 may be used instead of the contacts 20 and electromagnets; also that the tune-sheet may be of metal. This subject-matter does not appear in the Specification as accepted.
