Abstract: 1431369 Fertilizer from plantain B A QUAME 24 Oct 1969 [24 Oct 1968] 50973/75 Heading C1B [Also in Division A2] The sheath andvegetable of plantain are subjected to fermentation, the crude fibre being separated from the fermented material leaving a sheath and vegetable stock, the crude fibre being washed and dried thus obtaining a semi-purified fibre as a first recovery product. The remaining sheath is separated from the vegetable stock and subjected to destructive steam distillation, the vapours being condensed thus obtaining amorphous carbon product as a residue and a liquid containing various salts which may be recovered as a third recovery product. The remaining vegetable stock is blended with warm water to form a slurry which is separated into a solid meal and a milky liquid, the meal is pressed into solid cakes, which are dried and ground to an edible flour forming a fourth recovery product. The milky liquid is treated with CaCO 3  or a mixture of Ca(OH) 2  and CaCO 3  to agglutinate it forming a pulp-containing gel, separating the pulp from the liquid, drying it and grinding it to form a powder which may be used as a poultry feed or fertilizer and constitutes a fifth recovery product.

Title: Polyamide-forming compositions
IPC: C08G69/34
Filed: 1965-12-03
Abstract: A polyamide is prepared from a composition of (a) 1,4-bis-(b -aminoethyl) cyclohexane and (b) a polymerized fatty acid, or a polyamideforming derivative thereof, having a dimer content greater than 95%, the number of amine and carboxyl groups being substantially equal.  The fatty acid may be a saturated or ethylenically or acetylenically mono- or poly-unsaturated linear or branched natural of synthetic monocarboxylic acid having 8-24 carbon atoms.  Specified acids include linoleic, oleic and tall oil fatty acids.  The acid may be replaced by an ester with a C1- 8 alcohol.  The acid polymerization may be effected with the acid of heat and/or a catalyst, the product being fractionated by distillation or solvent extraction to provide a high enough dimer content.  The product may be catalytically hydrogenated before or after fractionation to reduce the degree of unsaturation.  In the polyamide-forming composition 5-90% of the polymerized acid may be replaced by a compound of formula: (a) R11OCOCOOR,11 (b) R11OCOR1COOR11, (c) NH2(CH2)xCOOR11 or (d) NH(CH2)xCO where R1 is a C1- 20 aliphatic <FORM:1056659/C3/1> hydrocarbon radical, a C6- 20 alicyclic or aliphatically substituted alicyclic hydrocarbon radical or a C6- 20 aromatic or aliphatically substituted aromatic hydrocarbon radical, R11 is H or C1- 8 alkyl, e.g. Me, Et, Pr or Bu and x is 2-15.  Specified compounds of these types include sebacic acid.  The polyamide condensation mixture may also contain a stabilizer, anti-oxidant, pigment or filler.  The condensation temperature may be 150-300 DEG  C.

Title: Variable inertia flywheel apparatus
IPC: G01L5/13
Filed: 1970-10-30
Abstract: 1,267,789. Testing vehicles. CLAYTON MFG., CO. Oct. 30, 1970 [Dec. 30, 1969], No. 51735/70. Heading G1W. A dynamometer for carrying out tests on a vehicle engine includes a variable inertia device 13 connected to the dynamometer rolls 7. Device 13 includes three flywheels A<SP>1</SP>, B<SP>1</SP> and C<SP>1</SP> of different weights each connected to a sheave which may be driven from a corresponding sheave on main shaft 14 by means of belts. Flywheel A<SP>1</SP> may be driven at either of two speed ratios relative to shaft 14 by means of two sets of belts 84, 90 acting on parts of the sheaves of different diameters. A control lever A selects either set of belts by moving an idler roller 218 or 220 so as tension belts 90 or 84 respectively, Fig. 5. Lever A also has a neutral position in which neither set of belts is tensioned and flywheel A<SP>1</SP> is not driven. Similarly, flywheel C<SP>1</SP> may be driven at either of two speed ratios or not at all as selected by control lever C, Fig. 4 (not shown). Flywheel B<SP>1</SP> may be driven at any of three speed ratios as selected by control levers B and B", Fig. 6 (not shown). Lever B<SP>11</SP> normally moves with lever B and this results in flywheel B<SP>1</SP> being driven in all three positions of lever B. This is advantageous since the arrangement of flywheel B<SP>1</SP> is such as to compensate for the inertia of the various dynamometer parts such as the rolls 7 and 8, at all three speed ratios. Levers B and B<SP>11</SP> may be positioned independently (positions 2 and 3 respectively in Fig. 13) to disengage the drive to flywheel B<SP>1</SP>. As shown in Fig. 13, by selecting a suitable combination of flywheels A<SP>1</SP>, B<SP>1</SP> and C<SP>1</SP> the inertia of a vehicle may be closely simulated.

Title: Method of producing low oxygen silicon-iron
IPC: C22C33/00
Filed: 1965-12-10
Abstract: Silicon-iron of low oxygen content for the manufacture of oriented silicon-iron sheet is produced by adding to ferrous metal in a first vessel sufficient silicon-bearing material (e.g. Fe-Si) to combine with the oxygen in the ferrous metal and leave therein a substantial residual quantity of silicon, adding sufficient manganese bearing material (e.g. electrolytic Mn) to the first vessel to bring the manganese content up to the final level, transferring the ferrous metal to a second vessel, adding sufficient silicon-bearing material to bring the silicon content up to the desired final level, adding aluminium to the ferrous metal and holding it in the second vessel for a period sufficient to allow inclusions to float out.  If the charge is subsequently made into cube-on-edge sheet the equivalent of at least 1 1/2 lb of 65% Fe-Si per ton of metal charge is added to the first vessel; if it is made into cube-on-face sheet the equivalent of at least 5lb of 65% Fe-Si per ton of charge is added.

Abstract: 1,182,046. Frequency measurement. AHREND-VAN GOGH N.V. 8 Nov., 1968 [10 Nov., 1967], No. 53040/68. Heading H3A. In a frequency measuring system, a capacitor 6 is charged by a constant current source 7, and is discharged by each impulse of a series to be measured, so that a sawtooth voltage occurs across the capacitor, of which the amplitude is proportional to the time interval between successive impulses, and from which a direct voltage is derived at 21 which is inversely proportional to the repetition frequency to be measured. A pulse generator 37, 38, Fig. 2, has its frequency modulated by this voltage, and its output is used to discharge a second capacitor 43 charged from a second constant current source 44 to produce a second sawtooth from which a direct voltage is derived which is inversely proportional to the frequency of the pulse generator, and which is thus directly proportional to the input frequency to be measured. In order to provide a smooth direct voltage at 21 from very low-frequency signals the voltage is smoothed by two capacitors 16, 17 alternately switched into circuit by a bi-stable 25 controlled from the input.
