Title: Ameliorations apportees aux lasers

Abstract: Système à laser pulsé possédant un miroir réfléchissant (M1) situé à proximité d'une extrémité de la chambre de décharge (L) et un autre miroir réfléchissant (M2) à l'autre extrémité de la chambre de décharge et qui est écarté de la chambre de sorte que l'impulsion lumineuse doit parcourir une certaine distance avant d'être réfléchie vers la chambre. Ceci a pour effet de racourcir la durée de l'impulsion. Bien que le mécanisme ne soit pas entièrement compris, on pense que le phénomène peut s'expliquer soit par le fait que l'impulsion retraverse la chambre lorsque le milieu de gain se transforme en absorption, ce qui provoque l'atténuation de la partie de queue de l'impulsion, soit par le fait que le système empêche la formation de crêtes multiples dans l'impulsion, ce qui se traduit par une impulsion lumineuse de courte durée.

Date Mar. 24, 1988.Method for cleansing gas from solid, liquid and/or gaseous contaminants, by bubbling the gas through a liquid bath (32), and by introducing the incoming gas into a distribution means (14) and causing the gas to pass in part-streams through a multiple of inlet orifices (64) located at progressively increasing depths beneath the surface (34) of the liquid (32). With increasing inlet pressure an increasing number of inlet orifices (64) are utilized for an increasing number of part-streams. The gas flow is passed from respective inlet orifices (64) through connecting means (24, 26, 28) to outlet orifices (31) located at a considerably higher height level (h) than corresponding inlet orifices (64). The gas flow is caused to flow out through venturi nozzles (28) and/or to strike against impinger or striking surfaces (39) with a minimum pressure drop corresponding to said height differential (h). In this way full operational pressure is immediately achieved, as soon as gas is passed out through any of the inlet orifices (64), and an intense mixing of gas and liquid as well as a high cleansing efficiency are guaranteed.

Abstract: A draft control apparatus for lifting and lowering an agricultural machine, such as a plow, which is attached to a tractor via a hydraulic lift unit, in such a manner that a plowing depth set in advance by a plowing depth setting device in accordance with an increase and decreased in the traction resistance detected by a draft sensor can be attained. When the lift unit for the agricultural machine is shifted from a lifting position to a lowering side, the agricultural machine is lowered suddenly with the draft control operation interrupted for a predetermined short period of time or by a predetermined short distance. When the relation between a detected value from the draft sensor and a set value from the plowing depth setting device is not on the agricultural machine lowering side, this sudden lowering operation is not carried out. Therefore, when the agricultural machine is lowered, it is driven into the earth excellently, and, moreover, it does not float above the ground surface after it has been driven into the earth.

Abstract: 1. A controllable speed driving device comprising a converter and a synchronous motor with permanent-magnet excitation. 2.1 As is known, the pole-wheel voltage induced in the armature winding by the permanent magnets increases with speed and it is thus normal also to allow the output voltage of the converter to increase with speed, the current taken by the synchronous motor being reduced accordingly. With the maximum power of the synchronous motor being constant, at the minimum speed of the controllable speed range the apparent power occurring is thus equal to the product Umin x Imax and at the maximum speed it is equal to the product Umax x Imin. Since the converter must be able to supply both the maximum voltage Umax and the maximum current Imax, its rated power is equal to the product Umax x Imax. The rated power of the converter is thus significantly greater than the maximum power of the synchronous motor. In the case of the new driving device, the rated power of the converter is intended to have a value which is as close as possible to the maximum power with respect to the maximum power of the synchronous motor in the operational speed range. 2.2 The converter (11) is operated at a constant output voltage in the operational speed range (nu, no), and the inductances acting in the circuit of the synchronous motor (12) are dimensioned such that, at the maximum power of the synchronous motor, the currents (Iu, Io) at the output of the converter are of equal magnitude both at the lowest and at the highest speed (nu, no). 2.3 Speed-controllable drives with permanent-magnet excited synchronous motors. <IMAGE>

Filed: 1988-07-06
Abstract: An improved ink jet recording method comprises the steps producing at least one ink jet (6) which disintegrates into 
a series of minute drops, selectively charging the drops to determine whether an individual drop, in a recording mode, is 
intended to travel along a recording path to impinge onto a predetermined location on an ink receiving surface (12) or is 
prevented to produce a record on said surface, deflecting each charged drop by an electric deflecting field by an amount 
depending on the charge of the drop (6), and effecting relative transverse motion between the path of the record producing 
drops and the record surface, determining any deviation between said predetermined location and an actual location of 
impingement of the jet, and applying an adjustable bias charge being chosen so that the deflection of the drop caused by 
the action of said electric deflecting field on said bias charge carried by said drop minimizes said deviation.

Abstract: A method and a composition for accumulating and the binding of food fats in an animal body gastrointestinal tract. The method and composition rely upon non-biodegradable particles, such as microspheres, having a size of at least two microns and a fat receptor, such as bile, capable of having food fat adhered thereto on the surface of the particles. These particles are sufficiently large so that they do not pass through the surface mucosa of the gastrointestinal tract and permit the particles with the food fat to pass through the gastrointestinal tract and out of the body through animal excretion.
