Title: Two-level sea-land creeping vehicle and method of operating same
Inventor: LOPEZ-IBOR ALINO FRANCISCO DR
IPC: B63G8/00
Filed: 1988-11-02
Abstract: A two-level sea-land creeping vehicle formed by three main parts: a frustoconical bow portion which is movable independently but connected to the central part or compartment in the form of a drop of water, which is flat in the lower part and which is fixed with respect to the rear part which comprises the drive and steering assembly, as well as the breathing and safety zone. 
     The vehicle is displaced on land by means of two rollers disposed in the lower region and by the drive of the motor, and it is likewise displaced on the surface of water due to its buoyancy and it is also displaced in a condition of dynamic immersion by the drive of the motor linked to positioning of the bow portion and hydroplanes; the air required is picked up from the surface by means of an appropriate telescopic arrangement and it has the particularity of not being hermetically sealed in the immersed condition. It is totally safe since it rises automatically to the surface when the motor stops.

Abstract: Binocular view finder enabling a wide field of vision, 60 DEG vertically by 120 DEG  horizontally, to be obtained. It is constituted, for each monocular vision channel, by an image generator (1A), for example a miniature cathode ray tube, by an optical relay (2A), by a collimation and combination optical system bringing together a holographic (H1) mixer plate (3A) for transmitting the landscape channel and reflecting the image channel and by a biconvex combining device (4A) formed from two holographic spherical optical elements (41, 42) used on the axis (H2, H3) for transmitting the two channels with collimation by diffraction of the image channel. A circular axial zone of zero photometric yield is produced for each monocular vision and is compensated by the overlap of the binocular fields of vision and, additionally, by the production of hologram mirrors having variable-index modulation. <IMAGE>

Abstract: Process for the conversion of petroleum hydrocarbons in the presence of catalyst particles in a fluidised phase in a tubular reaction zone with essentially upward or downward flow, this process comprising at least one stage of steam cracking of at least one light hydrocarbon cut and a stage of catalytic cracking of at least one heavy hydrocarbon cut. The steam cracking is carried out by bringing into contact, in a fluidised bed of catalyst particles, the said light hydrocarbons and a quantity of steam equal to at least 20% by weight, the resulting temperature being between 650 and 850 DEG C. The catalytic cracking of the heavy hydrocarbons is carried out by injecting into the catalyst suspension effluents from the upstream part of the reaction zone, so that the temperature of the mixture is between 500 and 650 DEG C and is then returned to a temperature of between 475 and 550 DEG C.

Abstract: Afin de permettre le traitement mécano-thermique de produits industriels difficiles à traiter, il est proposé ici une invention avec laquelle, grâce à la coopération des deux arbres agitateurs (2, 3) diamétralement opposés et comportant dans un carter (1) à deux cylindres des segments à disques, des couteaux (35, 36) fixés sur le diamètre extérieur, et des cadres racleurs (34) de segments en prise, les surfaces d'échange thermique demeurent exemptes de dépôts de croûte. Le produit est constamment broyé et homogénéisé. On peut obtenir un transfert longitudinal homogène avec des temps de séjour appropriés. Des brise-croûtes additionnels permettent de décomposer des produits grumeleux et d'empêcher les formations toroïdales. Plusieurs solutions différentes selon les produits sont possibles grâce à la modification et à l'agencement des organes malaxeurs et racleurs, grâce également à la modification du sens de rotation accompagnée d'une permutation des arbres agitateurs. Si on remplace les segments à disques par des bras agitateurs, on remplace aussi simultanément les cadres racleurs de segments par des cadres racleurs. Lorsqu'un seul des arbres agitateurs est équipé d'organes agitateurs (segments à disques ou bras agitateurs) auxquels sont fixés des couteaux, le deuxième bras agitateur ne reçoit en conséquence que des organes racleurs (cadres racleurs de segments ou cadres racleurs).

Abstract: The product according to the invention is a solution of macro­molecular compounds containing carboxyl and amide groups in a molar ratio of carboxyl groups to amide groups of 1:0,001 - 1:1. The product according to the invention is prepared from polyacrylonitrile hydrolyzate or acrylonitrile copolymer optio­nally supplemented with other polymers such as cellulose, cotton, albumin, polyamide and/or polyester in an amount of up to 10%. 
     The way of preparation according to the invention consists in neutralizing the hydrolyzate of acrylic polymers to a pH of 6.0 - 8.0, removing the excess of ammonia to 1 - 10 g/dcm³ and then in diluting until the concentration of the solution reaches 1 - 15% w/v. The hydrolyzate is then neutralized with organic and/or mineral acids at a temperature of 10 - 60°C, during more than 10 minutes under continuous agitation. The neutralized hydrolyzate is then to be diluted with water and/or organic solvents. 
     The treatment of seeds according to the invention consists in coating the seeds with a mixture of the seed incrustation product with plant pesticides optionally supplemented with nutrient media and dyes and removing the solvent from seeds after dressing. The product after being coated on the seeds builds up a polymer film that binds the dressing chemicals. The incrustation causes the dressing chemicals to be coated on the seeds in a uniform and firm way, the dosing to be precise and dosages of dressing chemicals to be optimized as well as dusting during dressing, packaging, transport and sowing to be avoided.

Abstract: A motor-driven power assisted steering control apparatus comprises a steering torque sensor (1), a motor (14) connected to a steering shaft via a clutch to thereby exert an auxiliary force for steering to the steering shaft and a control means (3,10) for controlling the motor in correspondence to an output from the steering torque sensing means, wherein a torque neutral point detector (23) detects the neutral point of steering torque, a first level detecting means (23) detects that a motor current exceeds a first level, and a second level detecting means (27) detects that the motor current exceeds a second level which is greater than the first level, whereby when the motor current exceeds the first level in a case that a steering torque value is at other than the neutral point, a current flowing in the clutch is reduced, and when the motor current exceeds the second level in a case that the steering torque value is at other than the neutral point, the current flowing in the clutch is interrupted to thereby stop the motor (14).

Abstract: In an iterative method of controlling the ink supply in a printing machine, a test area of the proof or proof substitute and a sheet printed during setting-up or the printing run as well as additionally printed individual colour areas of the printing inks used in the printing run are measured and represented as vectors in a colour space recommended by the CIE. A system of auxiliary coordinates is created along the axes of the individual colour vectors, and the two colour vectors of the test area colour of proof or proof substitute and current print are broken down into additive auxiliary vectors along the axes of this system of auxiliary coordinates. An empirical relationship is established from the absolute values of the auxiliary vector of the currently printed test area and of the individual colour vector lying in the same axis and this relationship allows the calculation of an individual colour vector from the previously calculated auxiliary vector of the test area colour. From the absolute values thus determined, an improved setting of the associated colour zone adjusting elements is derived, which serves as a basis for an iterative repetition of the method, which is continued until the difference between the test area colours of printed sheet and proof falls below a tolerance value below which it is not possible to go due to technical influences in printing. <IMAGE>
