Patent ES-292331-A1 (ES)
Title: Electric stress sensing devices for crushing machines
IPC: B02C2/04
Filed: 1963-10-09
Abstract: A crusher, e.g. a gyratory, roller, hammer or jaw crusher, includes a stress-sensing electrical device comprising a low-voltage source 12 connected to the main shaft, which is insulated from the movable crushing members, and to the frame of the crusher, and a control member in the circuit to stop the crushing action and/or switch in an alarm when a conductive object is present in the system. As described, the gyratory shaft 1 of a gyratory crusher is insulated by a plastics foot ring 2, and a plastics cross-bar bearing 3 and attrition ring 4, or alternatively the suspension ring 5 may be made of insulating material. Low voltage D.C. or A.C. is applied to the shaft 1 via a flexible lead 6, and to the frame 7, to control the servo-system 13 which controls an alarm device and/or relay circuit-breaker 14 for the motor. Tramp metal causes contact between the shaft and the framework, via the mantle, to close the circuit and actuate a sound or luminous alarm. Operation of the circuit may be delayed by a timer combined with the servo-control device 13, to permit the passage of small size metallic pieces. Deformations in mechanical members of the crusher are detected and controlled, e.g. by an extensometric gauge 15, secured to the shaft 1 at a suitably selected point, or e.g. on the arms of the cross bar 8. In a modification the control device 13 controls the opening of a hydraulic circuit, and flow back to an oil tank feeding an hydraulic lifting-jack at the upper end of the shaft, so as to permit passage of the blocking material between the mantle and crushing ring, after which the jack returns the shaft to its normal position. If however the metallic material is too large to pass, the electric circuit remains closed long enough to operate the alarm and/or stop the crushing motor. The electrical connection to the frame may be combined with the extensometric gauge, or the latter may be separate.

Title: Catalytic conversion of liquid petroleum hydrocarbons
Inventor: ROCHE ANDRE
IPC: C01B3/38
Filed: 1965-11-19
Abstract: In a process for the catalytic high pressure reforming of petroleum hydrocarbons with steam, the reaction mixture is passed first over a nickel catalyst on a support of a silicate of one or more of Al, alkali metal, alkaline earth metal (to convert the feed to CO2 and CH4), and then over a different catalyst having a volume 1 to 4 times that of the first (to react the CH4 with excess steam and CO2). The second catalyst is conventional, and optional components in the first are Co, Fe, Pt group metals, and oxides of alkali and alkaline earth metals. Both catalysts may be located in tubes, or the primary-reactor may comprise a single vessel, the second a bundle of tubes. Further, two primary reactors may be connected in parallel and used alternately, e.g. to permit catalyst regeneration where undesulphurized or unvaporizable hydrocarbons are used. The reaction mixture may be preheated. Four specific examples are described.
Patent ES-337751-A1 (ES)
Title: Dual scale interval timer
IPC: G04F3/02
Filed: 1967-03-08
Abstract: An interval timer comprises a rotatable interval indicating hand 26 attached by a shaft 32 to a partially toothed gear 62 and a pair of driving pinions 64, 65 successively meshing with the teeth 63 of the gear, the pinions being rotated at different speeds to drive the hand from a selected time interval position on a first scale marked 0-30 minutes or on a second scale marked 30 minutes-4 hours, the pinion 65 driving the gear 62 when the hand coincides with the second scale and the pinion 64 driving the gear 62 when the hand coincides with the first scale. Accurate timing of an interval of less than thirty minutes can be achieved whilst timing intervals of up to four and a half hours can also be accommodated with the compressed second scale. A synchronous clock motor 39 is mounted below a base plate 34 and has an output shaft 40 attached to which is a pinion 42 for driving a minutes gear train 35 comprises gears 43, 44, 46, 47, 49. The gear 49 drives a minutes shaft 27 and a minutes hand 24. An hours gear train 36 comprises gears 52, 53, 54, 56, the gear 52 being attached to the shaft 27. The gear 56 rotates an hours hand shaft 28 and an hours hand 23. The hours and minutes hands co-operate with a twelve hour dial concentric with the first and second dials on a plate 22. These hands are set by depressing and rotating a knob 25 so that projections 58 on a shaft 57 engage notches 59 in an extension 29 of the minutes shaft 27. On releasing the downward pressure on the knob 25, a leaf spring 37 engaging the lower end of the shaft 32 biases this shaft and the knob back to their original positions. The pinions 64, 65 are driven via friction clutches 67, 68 respectively so that the hand 26 may be rotated to the selected time interval indication without the resulting rotation of the pinions 64, 65 by the gear 62 causing rotation of the minutes or hours gear trains. Shafts 48, 66 on which the pinions 64, 65 are mounted, have their lower ends located on spring-loaded levers 100, 109 respectively so that the pinions are baised into engagement with the teeth 63 yet there is also sufficient play to enable the momentary engagement of both pinions with the teeth 63 at the thirty minute position of the hand 26. As the timing proceeds, the hand 26 rotates clockwise until it reaches the mark '0' on the dial whereupon both pinions 64, 65 are disengaged from the teeth 63 and the gear 62 is therefore stationary. At this instant a notch 95 on a cam 93 aligns with a projection 96 on a latch 86 which restrains a vibrator 79. The latch releases the vibrator which vibrates under the influence of the field of the synchronous motor frame 84 to produce an audible buzz. To stop the alarm, the hand 26 is manually rotated to the 'OFF' position and the projector 96 moves out of the notch 95 so that the latch again restrains the vibrator.

Title: Recovery of a cultivated micro organism and of residual substrate employed in the cultivation
IPC: C12N1/28
Filed: 1968-06-21
Abstract: A micro-organism capable of growth on a hydrocarbon is cultivated in the presence of a feedstock which consists of or contains a hydrocarbon and on which the micro-organism is capable of growth, in the presence of an aqueous nutrient medium and in the presence of a gas containing free oxygen and thereafter part of the aqueous medium is separated, the remaining product (or part thereof) comprising the micro-organism in admixture with at least part of the residual hydrocarbon and at least part of the residual nutrient medium is treated with a surface active agent having the formula:- where n is an integer from 11 to 14, m is from 4 to 12 and X is sodium or potassium, and the mixture so obtained is subjected to a separation treatment for the recovery of a fraction in which hydrocarbon predominates and a fraction consisting of or containing a mixture of micro-organism and water. The aqueous medium separated off may be replaced with fresh water to reconstitute the original mixture. The surface active agent is added in proportions within the range 0À02-0À5%, based on the weight of the mixture of micro-organism, aqueous nutrient medium and hydrocarbon. The surface agent is exemplified by an oxyethylenated lauric alcohol sulphate having on average 7 ethylene oxide groups per molecule and a sulphur content of 1.4% by weight. The recovered fraction in which hydrocarbons predominate, containing aqueous medium held in emulsion, may be treated to separate the surface active agent, as follows: (1) with a compound containing a metal ion which forms a water insoluble salt with the surface active agent e. g. calcium or barium hydroxides or carbonates, or salts of zinc and heavy metals (2) with a mineral acid e.g. HC1 or H 2 SO 4 , under conditions such that the surface active agent is hydrolysed (3) by cooling to a temperature in the range-10 degrees to +10 C. or (4) with a solvent e.g. 15-25% by weight of isopropanol. Examples are directed to the cultivativation of Candida tropicalis upon a gas obtained from Middle-East crude petroleum and to the recovery of the product yeast.
