Title: Arrangement for pivot link-forming means
IPC: B25J15/08
Filed: 1989-06-21
Granted: 1993-09-15
Abstract: A pressure medium-operated, pivot link-forming means, for example for robot arm, gripping and holding member or similar body (16), which is readjustable from a bent together position to a straightened out position and vice versa. The means (the body 16) is made of a flexible wall material, of a first type of wall portion having one or more locally defined, internal pocket formations (11) with associated pressure medium conduit (21) and of a second type of wall portions without such pocket formations. The first type of wall material is adapted to be deformed by inflating the pocket formation(s) and equivalently contracting the breadth or length of the adjacent wall portion. The second type of wall material forms a bracing portion for the wall portion(s) of the first type of wall material. The first type of wall portion is arranged spaced relative to the second type of wall portion so that the first type of wall portion can be bent together relative to the second type of wall portion by loading the pocket formation(s) (11) with pressure medium and can be straightened out relative to the second type of wall portion by discharging pressure medium from the pocket formation(s).

Abstract: What is described is a disintegrating igniter device for projectiles, grenades, cartridges, missiles and the like, consisting of a thin-walled aluminium sleeve, of a disintegrating ignition charge arranged in this, if appropriate of an ignition aid located in this charge, and of a flange piece arranged at the head end of the aluminium sleeve and having an axial bore, the aluminium sleeve being covered with a thin-walled plastic casing which is preferably produced from a shrinkable tube. Furthermore, there is preferably also a specially designed ignition aid which consists of ignition particles randomly distributed in the disintegrating igniter charge. Such a disintegrating igniter device is characterised by an especially clear-cut and reliable functioning, since its function pattern remains virtually unchanged even under the effects of a high load, such as occurs with the use of devices into which such disintegrating igniter devices are installed.

Abstract: Device and method for permanently checking the integrity of a transmission affected by parameters not directly accessible to measurement and whose influence on the modulus and phase of the field radiated in space can be determined by utilizing a mathematic model, the transmission being from an antenna array. Each antenna is supplied with one or more Hf carrier frequencies, each being modulated in a known way by one or more sinusoidal low frequency signals. First, a recording is made, at least at one point and during a time period T, of the amplitude of the combination of the signal received at this point and of a reference signal, having a fundamental frequency equal to one of the HF frequencies of the signal to be analyzed. Then, the amplitude of low frequency components of the signal thus obtained is extracted and memorized. Then, steps 1 and 2 are repeated n times (n is a whole number) in recording the signal at the same point and in carrying out, at each time, a phase shift of the reference signal by a quantity  <IMAGE>  k is a whole number successively assuming all values between 1 and n. The n amplitudes thus memorized are processed as the n values of function F( alpha k), from which values certain coefficients of its Fourier transform are extracted. The operations 1 to 4 are then repeated at least as many times as there are points of measurement. Values of the unknown parameters are then determined using the mathematical model.

Date Jun. 13, 1991.An apparatus for steering a forward end of a drill string having a motor. The apparatus includes a shaft connected to the motor. The shaft has a thickened portion. Drilling fluid having an operating mass flow rate, and a housing are provided. A piston is enclosed within the housing, and is displaceable by a mass flow of the drilling fluid. The piston has a central opening for the passage of the drilling fluid and has the shaft extending therethrough. The piston includes a displaceable sleeve within the housing, a first spring urging against the sleeve and the housing, and a displaceable piston part coaxial with the sleeve within the housing. The piston part has an inwardly directed collar movable towards the thickened portion of the shaft by an increase of the mass flow rate of the drilling fluid, whereby the collar and the thickened portion cooperate to reduce a size of the central opening, thus causing the drilling fluid to exert a thrust pressure on the piston part so that the piston part and the sleeve are moved abuttingly together against the urging of the first spring to an adjusting position. The piston is provided with a second spring exerting a spring force less than the first spring and having a first end urging against the sleeve, and a second end urging against the piston part. The apparatus further includes an adjusting organ connected to the sleeve and being displaceable when the piston is in the adjusting position.

Abstract: L'invention se rapporte à une bande adhésive en tissu servant à réunir des câbles en faiseau et utilisée par exemple dans le câblage d'une automobile. Des bandes adhésives de ce type sont utilisées dans la technique actuelle. Elles sont de trois sortes, soit avec un substrat en chlorure de polyvinyle, soit avec un substrat en tissu d'acétate, soit avec un substrat en tissu de coton. Les deux premières posent des problèmes de bruit, étant donné qu'elles génèrent des cognements ou des crissements pendant le déplacement de l'automobile et la dernière offre d'excellentes propriétés antibruit mais pose un problème du fait de sa faible maniabilité lors de sa manutention, car elle oppose une résistance élevée au déchirement. La bande adhésive décrite dans cette invention n'a pas ces inconvénients: elle se compose d'un substrat en étoffe tissée, dans lequel des fils toronnés, ayant chacun une résistance à la rupture par traction comprise entre 80 et 200 g, sont utilisés comme chaînes, et des fils filés ou des filaments à texture laineuse, ayant chacun une résistance supérieure à celle de la chaîne, sont utilisés comme trame, l'épaisseur de l'étoffe est d'au moins 0,2 mm, et la résistance à la rupture par traction d'une telle bande adhésive dans le sens longitudinal est à cet effet d'au moins 8 kg par largeur de 19 mm.
