Title: Improvements in catalysts
IPC: B01J23/28
Filed: 1932-09-19
Abstract: Catalytic masses are obtained by subjecting hydrated gel-like materials, such as silica and alumina gels or bauxite, to heat treatment at temperatures from 450--650 DEG  C. to increase their stability to impregnation and then impregnating the material with aqueous solutions yielding catalysts suitable for hydrogenation-cracking or destructive hydrogenation.  Indian bauxite which in its native state took up less than 3 per cent of ammonium molybdate was heated to 600 DEG  C.  The dry product after impregnation contained 18.5 per cent of ammonium molybdate and formed a catalyst suitable for the hydrogenation of tar under pressure to produce motor spirit and for the reduction at atmospheric pressure of tar acids to aromatic hydrocarbons. Carbon may be removed and the catalyst revivified by heating with air, oxygen or gases containing oxygen at temperatures from 450--600 DEG  C., for example, bauxite preheated to 450--650 DEG  C. was impregnated with 10 per cent of ammonium para molybdate and after reduction with hydrogen at 450 DEG C. was used in the reduction of m-cresol.  After ten mns., during which the catalyst was revivified three times, the amount of unchanged cresol in the product was 4.0 per cent.ALSO:Tar acids are reduced to aromatic hydrocarbons at atmospheric pressure in the presence of catalysts obtained by subjecting hydrated gel-like materials, such as silica and alumina gels or bauxite, to heat treatment at a temperature of 450--650 DEG  C. to increase their stability to impregnation and then impregnating the material with ammonium molybdate solution.  According to an example, such a catalyst is used for the reduction of m-cresol and after ten runs, during which the catalyst was revivified three times by heating with air, oxygen, or gases containing oxygen at temperatures from 450--600 DEG  C., the amount of unchanged cresol in the product was 4.0 per cent.

Sept. 22, 1932, No. 26385. Convention date, Sept. 30, 1931. [Class 40 (iii).] In a television system in which two sets of synchronizing impulses are transmitted with the picture signals in the same channel, the synchronizing impulses are separated from the picture signals by amplitude selection and the synchronizing impulses of one set are developed with a steepness of wave front substantially different from that of the other set. The picture is scanned by the usual spiral of apertures 12 and the line frequency impulses of greater amplitude are produced by a circular ring of apertures 10<a>, 11<a> ... co-operating with a separate photo-electric cell whilst the impulses at the picture frequency are produced by a special aperture 20 formed with a tail portion 21. At the receiver the combined signals are fed to an arrangement controlling the intensity of the cathode beam 34 whilst an opposing battery 41 prevents the passage of the picture impulses to the valve 40 in whose output circuit are arranged devices 38, 39 which are fed with waves to deflect the screening beam vertically and horizontally by means of coils 36, 37. A condenser 44 prevents the higher synchronizing frequency from reaching the control arrangement 38. The synchronizing impulses are arranged to produce a " black " effect on the receiving screen 35, and the picture synchronizing impulse is prolonged by the shape of the tail portion 21 so that the cathode beam is non-effective on the receiving screen during its passage from the end of the last line to the beginning of the first line of the received picture. Specification 392,383 is referred to.

Abstract: 1283469 Crop-working implements P W ZWEEGERS 3 June 1970 [5 June 1969 11 July 1969] 26792/70 Heading A1F An agricultural implement for working crop lying on the ground has at least one rotary element 4, 5 carrying a circular array of crop working means (tines 14, 15) and is rotatable in a horizontal plane or preferably inclined at a slight angle to the ground (Fig. 2). The tines are fastened to supporting arms 16 which are pivotably mounted onto the rim 22. Biasing torsion springs maintain the tines in position 18 (Fig. 2) when the rotation of the element is stopped but the centrifugal force on the tines on rotation causes them to adopt the full line position. The extreme operative and inoperative positions are defined by stops e.g. contact of the tines with rim 21 and the arms 16 with rim 22. The pivot pins of the tines may also be rotatable about an axis substantially parallel to the axis of the element to give alternative inclinations of the tines to the rims - these positions maintained by a spring-loaded locking pin. The inclination of the element to the ground is also adjustable. The implement is fixed relative to the towing tractor by means of link 11 (Fig. 1).

Locating conductors; magnetic tests.-In the process for electrically exploring the ground forming the subject-matter of the parent Specification, the ground currents and magnetic fields due to them are determined by measuring the amplitude and phase of their components parallel to the axis of the same right-angled, oblique-angled, or polar system of co-ordinates at all measuring points. These amplitudes and phase angles are marked on cards and lines of equal values of amplitudes and phase angles are traced. When probes are employed they are arranged at all measuring points at equal distances from each other and successively in east-west or in northsouth direction and the components of the tension vector on the ground are determined in both positions with relation to amplitude and phrase angle, the vertical component being also determined in measuring below the surface of the ground. When using the induction frame method, the frame is brought at all measuring points successively into east-west, north-south, and horizontal positions in order to determine the three co-ordinates of the amplitude and phase angle of the magnetic field vector.
