Title: Process for the production of higher alcohols
IPC: C07C29/34
Filed: 1931-06-25
Abstract: Higher alcohols are prepared by passing a mixture of hydrogen with the vapour of both methyl and ethyl alcohols over catalysts comprising an alkaline-earth metal oxide, particularly magnesia, activated by the presence of less than 10 per cent of one or more of the oxides of the metals lead, thorium, silver, uranium, tungsten, cadmium, tin, chromium, manganese, zinc, iron, nickel, cobalt, and copper.  The reaction is effected below 400 DEG  C., preferably between 200 and 350 DEG  C., at ordinary or increased pressure, and using one-half to three molecular proportions of hydrogen (a molecule being regarded as H2) per molecular proportion of alcohol mixture. The catalyst may be stabilized by the addition of aluminium oxide or hydroxide, titanium oxide or hydroxide, stannic acid gel, silica gel or wood charcoal; the influence of the latter is stated to persist even after the usual regenerative treatment with oxidizing gases or steam at temperatures of 300-500 DEG  C.  Pretreatment of the catalysts with moist gases containing oxygen is advantageous. Examples are given of the preparation of (1) a product comprising n-propyl alcohol, isobutyl alcohol, n-butyl alcohol, methylethylcarbin carbinol, hexyl, heptyl, octyl and nonyl alcohols by use of a catalytic mixture of magnesium, aluminium and copper oxides, the pressure conditions being atmospheric; unchanged methyl and ethyl alcohols, as well as the small quantities of acetaldehyde and butyraldehyde formed, are returned to the reaction; (2) a mixture of n-propyl, isobutyl, n-butyl and higher alcohols with methylethylcarbin carbinol, using the same catalyst as in (1), but at a higher temperature and the gases under a pressure of 30 atmospheres.  Specification 364,134 is referred to.ALSO:Catalytic materials for the preparation of higher alcohols from a mixture of methyl and ethyl alcohols in the presence of hydrogen comprise an alkaline earth metal oxide, particularly magnesia, activated by the presence of less than 10 per cent of one or more of the oxides of the metals lead, thorium, silver, uranium, tungsten, cadmium, tin, chromium, manganese, zinc, iron, nickel, cobalt and copper.

Title: Automatic starting system for engines
Filed: 1931-06-27
Abstract: 381,173. Starting prime movers. BRETTELL, F. G., 59, Chancery Lane, London.-(Startomatic Corporation ; 1627, West Pico Street, Los Angeles, U.S.A.) June 27, 1931, No. 18652. [Class 38 (iv).] A prime-mover is automatically restarted when stalled, provided that a manually controlled starting switch is closed. An electromagnetic switch in the starting motor circuit is held open so long as the engine is running, but closes under dashpot retardation when the engine stops. The circuit arrangement is shown in Fig. 10, and the switch construction in section in Fig. 2. The engine 11 drives a generator 23 which charges a battery 17. The circuit of the starting motor 15 includes a switch 26 closed by a solenoid 27 in a circuit controlled by the ignition switch 19 and a switch 30 held in closed position by the spring 127. When the switch 19 is closed the starting motor is operated and a coil 31 in series with it maintains the switch 30 in closed position in opposition to the pull of a coil 36 in shunt with the starting motor. The fall of current in the coil 31 which occurs when the motor 15 speeds up allows the coil 36 to draw the core 100 into contact with a fixed core 96, opening the switch 30. The pull of the coil 31 is adjustable by a screw 109 which varies the air gap 111, Fig. 2. Reclosing of the starting motor circuit by the switch 30 is prevented by the saturation of the cores 100, 96 and by the energization of coil 36 by the back E.M.F. of the motor 15 during its deceleration. The generator 23 now energizes a coil 37 and maintains the switch 30 open against the pull of the spring 127 so long as the engine is running, so that, until the ignition switch 19 is opened, the starting motor will come into operation when the engine stops. A demagnetizing coil 139 may be provided, energized through the ignition switch. The switch 26 is closed by the solenoid 27 against a spring 56 and a dashpot 60 which introduces an adjustable time element. An extension of the core of the solenoid carries a cup leather 62 between two washers ; these are perforated and cooperate with a pliable valve disc and a plate adjustably pressed against them by a spring and nuts. The terminal 108 to which the starting motor is connected comprises two members united by fusible alloy 116 so that the starting motor circuit is interrupted by the separation of the members if the motor fails to function when its circuit is closed.

Title: Improvements relating to the finishing of textile materials composed of or containing animal fibres
IPC: D06M23/00
Filed: 1943-11-11
Abstract: 573,322. Finishing textile fibres and fabrics. FULLERS' EARTH UNION, Ltd., SPEAKMAN, J. B., and WHEWELL, E. Nov. 11, 1943, No. 18770. [Class 42 (i)] [Also in Group IX] A process for the treatment of textile materials, including animal fibres and fabrics composed of or containing such fibres, consists in mechanically working the material with an abrasive powder, e.g., Fullers' Earth, silica, kaolin, " Carborundum " (Registered Trade Mark), or mixtures thereof, in the presence of a non-aqueous medium, e.g., olive oil, in which the powder is not soluble, for a sufficient time to wear away the surface scales of the fibres and thus render the material substantially unshrinkable during subsequent laundering, the non-aqueous medium and the powder being then removed by scouring. A woollen fabric in the dry condition may be first filled with the abrasive powder, then impregnated with the oil and subsequently milled. In an example, 170 parts by weight of all-wool flannel were filled with 50 parts of powder, then impregnated with 250 parts of olive oil and worked, for one hour, in a milling machine. Depending upon the abrasive powder used, and its grain size, the reduction of the percentage shrinking in area as between an untreated and a treated fabric is stated to be of the order 49.3 to 19 per cent.

Title: Improvements in or relating to directional aerials
IPC: H01Q11/18
Filed: 1932-07-02
Abstract: 403,949. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and FRANKLIN, C. S., Marconi House, Strand, London. July 2, 1932, No. 18779. [Class 40 (v).] A short - wave aerial, designed to radiate a concentrated field in one direction only, without the use of a reflector, comprises a series of open-ended loops ABCD, EFGH, &c. arranged at an angle to the general line A to Z of the aerial, and connected in series by spacing elements DE, HI, &c. The arrangement is such that the radiation from the elements AB, CD, EF, GH, &c. is additive in one direction, and zero in the opposite direction, whilst the radiation from the remaining wire elements is substantially nil. The aerial is energized at S through a line L1, and may be earthed at the opposite end through a line L2 and surge-impedance R. The wires AB, CD, EF &c. are each a quarter wavelength, the wires BC, FG, &c. are a small fraction, say onetwentieth of a wavelength, whilst the wires DE, HI, &c. are each a quarter wavelength less the length of the wire BC or FG. In effect each loop ABCD, EFGH, &c. acts as a quarterwave aerial, radiating additively in the direction from Z to A and cancelling out in the opposite direction. The radiation from the wires DE, HI, &c. is substantially zero. The points B and C or F and G &c. may coincide, making each loop into an inverted V. By changing the spacing of the loops along the line, the aerial will be effectively unidirectional over a wide band of frequencies. The main direction of radiation may be reversed or given any desired angle by varying the disposition of the loops. In Fig. 3 the loops are set at an angle. Several such aerials may be supported from a single mast.
