Abstract: 491,933. Electromagnetic switches. BRISTOL AEROPLANE CO., Ltd., FEDDEN, A. H. R., and KLEYNOT, E. March 11, 1937, No. 7221. [Class 38 (v)] [Also in Group XXXV] A switching device controlling an automatic temperature-regulating apparatus for an internal-combustion engine comprises a moving coil galvanometer supplied with a current dependent on the engine temperature. The pointer 16 of the galvanometer takes up a position dependent on the temperature when coils 22, 23, which are energized through a continuously operated interrupter, are deenergized. If the engine temperature is higher than normal the pointer 16 takes up a position nearer to the core 21 of coil 23 than to the core 20 of coil 22 so that on energization of the coils 22, 23 the pointer 16 is attracted to make contact with the copper plated tip 25 of core 21, thus closing a circuit energizing means to effect increase of the rate of cooling. If the engine temperature is below normal the pointer 16 is moved to contact tip 24 of core 20 closing a circuit energizing means to effect decrease of the rate of cooling.

Patent GB-874583-A (GB)
Title: Purification of alcohols
IPC: C07C29/74
Filed: 1960-03-02
Abstract: Alcohols contaminated with carbonyl compounds are purified by contacting them with from 0.5 to 50 gms of a Lewis acid per litre of alcohol for a time sufficient to convert the carbonyl contaminants to higher boiling materials and separating alcohols having a reduced carbonyl contact.  The process is particularly useful for the treatment of oxo alcohols containing 6-16 carbon atoms.  Suitable Lewis acids are, for example, transition metal halides such as the chlorides and bromides of tin and aluminium, ferric chloride and zinc chloride; boron trifluoride, hydrofluoric acid, sulphuric acid, phosphonic acid and phosphorus pentoxide. Preferred temperatures for carrying out the process are from 60 DEG  to 80 DEG F.  After treatment with the Lewis acid the alcohol-containing mixture is preferably neutralised and washed with caustic soda and water to remove the acid.  The product is then fractionated to obtain alcohol of high purity which on esterification, e.g. with phthalic acid, gives a substantially colour-free ester.

Abstract: 526,120. Knitting. HEMPHILL CO. March 8, 1939, No. 7547. Convention date, March 9, 1938. [Class 74 (ii)] A machine for knitting fabrics having pile loop areas is provided with sinkers over which pile loops of different length can be 'drawn and with patterning means for selectively positioning the sinkers to draw the different length pile loops. The entire area of fabric may have pile loops 168, 169, 170, 171 of different lengths in which case, due to the sinker movement in forming the pile loops, the whole fabric is reverse-plated, or alternatively part only of the fabric may be provided with pile loops, the reverse-plated pile loops .appearing on the same face as the loops of ordinary length formed from the same yarn 160. If the yarn 160 is of silk of a greater lustre than the other yarn 159, the reverse face of the fabric will have a watered or moire effect. The sinkers 26 are provided with a nib 38 over which long pile loops are formed, a throat 39 receiving the ground .yarn, and a notch 40 over which shorter pile loops are formed. Patterning jacks 43 are provided below the outer ends of the sinkers, so that selected sinkers can be raised so that butts 42 thereon are brought into the range of an upper cam 75. The cam 75 and a cam 76 immediately beneath it are movable by hand into positions such that the sinkers can be actuated so that either both yarns 159, 160 are taken in the throat 39, or some sinkers take the pile yarn 160 upon the nib 38 while the ground yarn is taken in the throat 39 and at the same time the remaining sinkers take the pile yarn in the notch 40, or alternatively the pile yarn is taken by all sinkers either in the notch 40 or upon the nib 39. The upwardly projecting butt 42 of the sinker may be notched as at 44 so that it can be held by a knife-edge cam in its raised position and the nib 39 may be notched as at 153, Fig. 7. The sinkers may have butts 31 actuated by jacks arranged in the needle tricks so as to assist in the stitchdrawing as described in U.S.A. Specifications 2,090,500 and 2,104,231, and the needles may be selected for tuck or float work by patterning mechanism in the form of manually set plungers as described in Specification 444,044. The lower edge 128 of the yarn guide 125 for the ground and pile yarns is sharp and serves to open the needle latches, and drop wires 135, 136 serve to operate on electrical stop-motion of known form upon breakage of or undue slackness in either of the two yarns. Specifications 445,451, 447,370 and 493,589, also are referred to.

Abstract: 116,130. Bourke, A. M. May 26, 1917. Buoy signals; signals indicating proximity of vessels; subaqueous audible signals.-Magnetic effects are utilized for detecting iron ships and determining their positions, speeds, and courses. Fig. 1 repre. sents two ground cables a, b having attached at intervals buoys d - - d<5>, e - - e<5>, which are magnetically attracted to an iron vessel h. Fig. 2 shows a buoy 1<a> anchored to the cable a, and Fig. 6 shows the interior of one form of the buoy. The core 2a of an electro-magnet 3<a>, excited by a current transmitted from the shore, protrudes from the buoy. A sound chamber 6<a> is supported by gimbals 7 from the base of the magnet so as always to hang vertically, a weight being preferably affixed to ensure this. The bottom of the chamber 6a is furnished with a number of radially-disposed sets of flat spring tongues 9, which are adapted to be plucked by a plectrum 8<a> fixed relatively to the buoy. When the buoy is inclined by its attraction to a vessel in the neighbourhood, the direction and amount of its inclination, and the rate of change thereof, can be deduced from the sound emitted by the plucked tongues 9, each of which has a characteristic note. The sound is conveyed by a tube 12 to a telephone located near the cable a and connected to the shore station, and recording-devices may be there provided. Knowledge of the simultaneous inclined positions of all the buoys will give the position of the ship. Sounds traversing the water itself will also be communicated to the chamber 6<a>, and may be heard from the shore. Means may be added for code signalling from the shore to the vessel, consisting of a striker 18 forming the core of a solenoid 19 energized from the shore, Fig. 6 showing connexions whereby the current therefor may be tapped from the leads 28, 30 to the coil of the magnet 3<a>. The striker 18 vibrates the core 2<a>, causing sound waves to traverse the water for detection by any vessel within range.

Abstract: 548,236. Control systems for resistance welding &c. FERRANTI, Ltd., and ATKINSON, L. June 18, 1941, No. 7695. [Class 38 (iv)] Switching and thermionic control. Current is supplied from A.C. mains for a period limited to a half-cycle through an ignition 7, the ignition electrode 10 of which is in the charging and discharging circuits of a condenser 12. During negative half waves of potential on the anode of the ignition the condenser is charged through a half wave rectifier 15. A gas filled relay valve is arranged to discharge the condenser during a single positive half wave of potential on the ignition. As shown the relay valve 18 requires excitation of both of two control electrodes 21, 28 to become conductive. The valve 18 fires when the condenser potential through the potentiometer 20 sufficiently excites electrode 28 and when a switch 26 is opened to permit the peaky wave output of a transformer 25 to excite electrode 21. The instant of ignition is determined by a phase shifting circuit (not shown) supplying the transformer 25 and the current period is terminated by the reduction of anode potential on the ignition. In an alternative arrangement the switch 26 is placed in series with the potentiometer 20.

Abstract: 549,998. Projectile fuzes and apparatus for setting the same. CLAESSON, M. A. June 20, 1941. No. 7800. Convention date, June 21, 1940. [Class 9 (i)] [Also in Group XL] In a gaseous discharge tube system arranged to produce an electrical impulse with variable time delay adapted to operate a fuze for igniting a priming composition in a projectile or the like a timing condenser is provided and so arranged that the time increases with increase of the voltage to which the condenser is charged. A current of limited value may be passed through the tube immediately before operation to increase the constancy of the starting potential as described in Specification 548,405. Fig. 6 shows an arrangement in which an ignition condenser. C' is charged to a voltage U higher than the starter potential Vt of the tube G while the timing condenser C2 is charged to an opposing voltage V and the time interval is determined by its discharge through resistance R until the tube ignites and operates fuze F. When voltage U = Vt x a where a is a constant the timing interval is independent of the voltage Vt. A safety switch S operated by the acceleration of the projectile may be provided. Fig. 7 shows an arrangement for applying the required voltages to condensers C<SP>1</SP>, C2. A voltage equal to the starting potential of the tube G is obtained across the points 4, 5 since condenser C' is charged over resistance L until the tube G ignites when relay P is operated over an amplifier H to break the charging and discharging circuits at contacts p<SP>1</SP>, p<SP>2</SP>, respectively, which voltage with the addition of constant voltage M is used to charge the condenser C<SP>1</SP>. Condenser C<SP>2</SP> is charged to the voltage required to produce the desired time either by manual adjustment or the timing voltage is automatically derived from the firing control device adjusted in accordance with the ballistic parameters. The voltage source M may be variable to control the sensitivity at various ranges and the condenser C<SP>3</SP> may be discharged by a protective resistance. As applied to the firing of shells, these may be fed so as successively to pass current through the tube, to charge the ignition condenser and in a third position to charge the timing condenser, the last position being the firing position. Specification 408.706, [Croup XXXVIII], also is referred to.
