Title: Purification of alcohols
IPC: C07C29/74
Filed: 1961-06-12
Abstract: An alkanol having 6-10 carbon atoms and contaminated with colour-producing oxygenated organic compounds is decolorised by treating with an aminoalcohol and separating an alkanol of improved colour from the resulting mixture.  The process may be applied to mixtures of alkanols containing 6-10 carbon atoms. Preferably the amino alcohol contains one hydroxyl group and one amino group, e.g. monoethanolamine, monopropanolamine and monobutanolamine.  The treatment may be carried out at 20 DEG -200 DEG C., preferably 60-80 DEG C.  It is preferred to have also present a weak organic acid, e.g. glacial acetic acid, propionic acid and butyric acid.  The purified alcohol product may be used in the preparation of esters, e.g. by reaction with dicarboxylic acids or anhydrides such as phthalic anhydride, adipic acid, azelaic acid and sebacic acid.  The esterification is carried out in the presence of sulphuric acid at 130-180 DEG C.  Specification 804,335 is referred to.

Filed: 1965-05-19
Abstract: 1,081,545. Galvanic cells. JUNKALOR DESSALL, VEB. May 19, 1965, No. 21179/65. Heading GIN. Partial pressure of, for example, oxygen is measured by means of a solid electrolyte galvanic cell comprising a porous tube 1, Fig. 1 carrying a platinum mesh electrode 2 secured on the outside of its closed end by a coating 4 of glass, a similar electrode mounted on the inside of the closed end, and a chemical substance 7 contained at the bottom of the tube which substance under an increase in temperature produces oxygen and exerts a reference oxygen partial pressure, any difference between this and the partial pressure of the oxygen outside the tube producing an e. m. f. between the electrodes. The tube is of zirconium oxide which with increased temperature produces mobile ions therein and constitutes the solid electrolyte. Its open end is sealed by a glass plug, applied as a suspension of glass powder in alcohol and glycerine, and subsequently fused. The platinum mesh electrodes may be painted with a nitro cellulose adhesive containing platinum particles. The remainder of the tube is filled with Al 2 O 3 . A thermocouple may be provided at the electrode end of the tube, by welding a rhodiumplatinum wire (11) to the mesh (at 10, Fig. 3, not shown).

Title: A reading arrangement for a magnetic memory
IPC: B07C3/00
Filed: 1965-05-19
Abstract: 1,102,721. Recording and playback. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 19 May, 1965 [22 May, 1964], No. 21198/65. Heading G5R. [Also in Division B8] To determine the position of a magnetic spot on a magnetizable carrier, a head arranged with its sensing direction perpendicular to the carrier surface detects the flux component at rightangles to the surface. When an indicator connected to the head shows that the flux sensed by the head is passing through zero, the position of the spot is determined. The system is of use in determining at which times to unload goods from a conveyer. A drum with a magnetic surface having a permanent magnetic polarization rotates in conjunction with the movement of the conveyer and has a number of tracks corresponding to the number of possible unloading stations. When an item is loaded on to the conveyer a write head on the appropriate track is energized to provide a magnetic spot on the drum. When the spot subsequently passes a corresponding read-head, the zero passage of the perpendicular component of the magnetic flux is sensed and the signal used to operate the corresponding unloading mechanism of the conveyer. Read-head.-The head for sensing the static perpendicular flux component may consist of a sense winding 20 with its axis in the perpendicular direction inside which is a core 21 of square loop material carrying windings 22, 23 to which a 50 kc/s. switching signal is applied. No voltage is induced in the winding 20 in the absence of an external field, due to the arrangement of the windings 22, 23, but when an external static flux links the core, an output signal of amplitude determined by this flux and of twice the switching frequency will be obtained from the winding 20. This signal is passed via a filter and a phase-sensitive rectifier to an amplifier discriminator arrangement which produces a pulse when the flux signal passes through zero. Alternatively a read-head comprising a Hall element can be used for the static reading of the perpendicular field.

Abstract: 642,602. Dowel pins. SCOTT. L. B. Aug. 5, 1947, No. 21241. Convention date, March 3,1939. [Class 89(ii)] [Also in Group XXII] To repair a body at points subjected to strain or to reinforce or prevent leakage from a cracked or fractured body, e.g., engine cylinder or manifold, the metal adjacent the crack, &c., is removed, recesses are formed in two opposite walls of the opening so formed, and pliable metal sealing means is pressed in to engage said recesses. A groove 11 may be cut in a casting 10 to overlie a crack a and holes 14 be drilled in the side walls of said groove. One of each pair of opposed holes may be threaded at 14<1> and bars 17 successively screwed in after pliable metal or other packing 16 has been inserted. Each bar of the first row is pressed to enter the unscrewed end and flatten it before further packing and another row of bars are introduced, This is repeated until the groove is filled as at Fig. 6. If desired the groove may be cut at right angles to the crack so that the repair will distribute the strain over a greater area of sound metal. Any number of bars may be used and the greater part of the groove may be filled with packing only as in Fig. 8. The side walls of the groove may be sloped. A strip 18, Fig. 16, with pairs of lugs 19 to enter the holes 14 may be arranged lengthwise of the crack in place of a row of bars 17. Fig. 13 shows a modified strip, the groove being cut to fit the lugs 20. Figs. 14, 15 show a form for surface application, the lugs 25 engaging corresponding recesses giving additional strength. When the weakened metal surrounding a crack is extensive, a long bar, Fig. 19, with 'pins at its ends to engage sound metal. may be used.

Title: Improvements in or relating to apparatus for obtaining a combustible gas by fermentation of organic materials
IPC: C12M1/107
Filed: 1947-08-05
Abstract: <PICT:0621771/IV (b)/1> <PICT:0621771/IV (b)/2> <PICT:0621771/IV (b)/3> In the two-stage fermentation process of the parent Specification, the heat emitted in the first stage is transferred between two or more vessels through the medium of a fluid, and used to heat material undergoing the second stage.  The vessels may be jacketed and air circulated to give a temperature of 60-90 DEG  C. in the exothermic vessel, the hot gas passing to the jackets of methane vessels, leaving at, say, 40 DEG  C., and passing in heat-exchange with fresh humidified air before discharge.  Used air may be mixed with the fresh to limit the oxygen content and therefore, the temperature produced in the first stage.  Gasometer vessels as described in Specification 621,746 may be used, and gas circulation made through flues, hollow bricks or a chimney, which may be automatically regulated.  Uniform operation is effected by periodic partial removal of fermented material and partial recharging by an upper trap-door.  Water circulation may alternatively be used for heat transfer by direct contact with the hot vessels or heat exchange with the hot gases evolved.  The jackets may be replaced by a pipe system or nests of tubes inside the vessels.  Where liquid manure is circulated, particularly by automatic means as described in French Specification 818,680, this may be used to transfer heat.  The end of the exothermic phase is p  determined by a negative starch test using iodine.  Fig. 1 shows an aerobic vessel 1, and methane vessel 2, fresh air at 3 circulating in jacket 4, passing through heat exchanger 6 and, mixed with air from the jacket 12 of vessel 2, passing into vessel 1 by line 8, leaving by line 11 for circulation in jacket 12 before return in part to line 8, and in part being discharged at 14 after traversing heat exchanger 6.  In Fig. 2, gasometer vessels 17 are coupled with an aerobic fermentation vessel 18, air from inlet 20 passing down through the latter, into jacket 21, and leaving by passage 23.  The jackets are preferably constructed of bricks, each having cavities 33, 34, Fig. 4, separated by a partition 35 from an open portion filled with cellular concrete. These are arranged in two courses, staggered by half their height. The outside bricks may be completely filled with concrete.

Abstract: 820,063. Tractor power-lift mechanisms. INTERNATIONAL HARVESTER CO. July 8, 1957 [Oct. 5, 1956(2)], No. 21537/57. Class 79(1) In a tractor, twopoint type implement attaching means comprise a draught structure 14 with its forward end 15 pivotally attached to an anchorage on a tractor body 10, laterally spaced implement attaching elements 25-26 pivoted on a transverse axis 27 to the forward end 15 and a lifting mechanism on the tractor that includes a substantially vertical link 45 attached rearwardly of the axis 27. The arrangement has the effect of establishing a virtual hitch point at the intersection "A" of lines drawn along links 15 and 46 (Fis. 7). The elements 25 and 26 are sockets with means 31 to support, and a spring catch 33 to retain, members 29 attaching an implement such as a mouldboard plough. The socket members 25 and 26 are urged into alignment with arms 16 and 17 forming the forward' end 15 by a leaf spring 85 which bears against extensions 28 on the arms. The link 45 is one or a pair of parallel telescopic links 45, 46 and is itself formed with a screwed rod 54 engaging in a screwed sleeve 55 so that the draught structure may be manually levelled by turning a handle 58. Lateral stabilizing means are provided comprising transversely-pivoted arms 92 supporting a rotatable transverse shaft 91 to which the socket 26 is connected by a pair of links 96 on vertical pivots 97 and 98. A pin 101 working in a slot 100 in a plate 95 limits the lateral movement to that necessary for the plough to follow the tractor. Lateral movement can be eliminated, if required, by moving the pin into a hole 101a. The forward end of the arms 16 and 17 are pivoted on trunnions 19 projecting from opposite sides of a ball 20 which has universal movement in a socket 21 formed in the lower end of a lever arm 22 that is fixed to a shaft 23 rotating in a bracket 24 affixed to the tractor body 10. The arm 22 forms the first member of a linkage described in Specification 820,064 which causes the mechanism 44 to lift the implement and so transfer some of its weight to the tractor when the tractive effort is increased due to heavy soil. The draught structure 14 is moved from the operating to the travelling position or lifted and lowered as required to engage the implement attachment 29 in the sockets 25 and 26 by a hydraulic cylinder 61 and ram 68 interposed in the aforementioned linkage.
