Abstract: Le procédé décrit, qui sert au guidage d'un instrument utilisé lors d'une intervention de neurochirurgie, permet de réduire considérablement les traumatismes chirurgicaux lors de l'enlèvement de lésions cérébrales grâce à la possibilité de convertir en images tridimensionnelles à la fois les contours des structures anatomiques et la représentation du dispositif pour la détection stéréotaxique de la région affectée, avec une sonde stéréotaxique qui définit une trajectoire chirurgicale. L'appareil de réalisation du procédé mentionné ci-dessus comprend un organe (4) servant à transférer les images radiologiques bidimensionnelles (5) provenant d'un dispositif de tomographie axiale informatisé ou à résonance magnétique à un ordinateur (6), lequel est équipé d'un écran de visualisation et comporte un organe processeur permettant de convertir les images bidimensionnelles en images tridimensionnelles (8) avec représentation tridimensionnelle schématique du dispositif de détection stéréotaxique (3).

Inventor: MICKELER REINHOLD
IPC: B60R21/01
Filed: 1990-05-09
Abstract: A trigger device for safety systems in vehicles is described. It comprises a pyroelectric trigger element (2) to which an electronic lock (4) and a controlled switch (3), which enables the activation of the trigger element with current, are assigned, said elements being preferably combined into a single-unit component. Supplying a trigger signal (9B) only leads to the trigger element being fed with current after an unlocking signal (9A) has been transmitted. As a result, an undesired triggering, for example due to an extraneous voltage being accidentally applied to the terminals of the trigger device, is reliably prevented. The reactive trigger substance can be directly connected to a silicon chip which realises the electronic lock (4) and the controlled switch (3) in a monolithic fashion. <IMAGE>

Abstract: For a transmitter for the measurement of mechanical forces by means of a preferably strip-shaped measuring body made of amorphous magnetoelastic metal, an absolutely creep-resistant and heavy-duty fastening of the ends of the measuring body is proposed. For this, the ends of the measuring body are fixed to winding-spindle bodies (1, 21) by winding a plurality of layers on the winding bodies (1, 21) and thereafter fastening the winding bodies (1, 21) in the respective transmitter. The outer end of the measuring body is attached to a winding body (1, 21) by being clamped in the winding body (1, 21). For this, the winding body (1, 21) consists in a specific axial portion (2) of two parts (5, 6) which are connected to one another by means of a film hinge and which are folded together after the end of the measuring body has been inserted. <IMAGE>

Abstract: A method for breaking the fracturing fluid comprises injecting into the subterranean formation a controlled release breaker capsule including an enclosure material enveloping a breaker. The enclosure material is sufficiently permeable to at least one fluid existing in the subterranean environment or injected with the controlled release capsule such that the breaker capsule is capable of rupturing upon sufficient exposure to the fluid, thereby releasing the breaker. 
     Using the method of the present invention, breaking of fracturing fluids is significantly improved when the tempera­ture in the subterranean environment is from about 20°C to about 65°C.

Abstract: A momentary decrease of the line voltage level, is used to control a momentary decrease of the level of supply loads, is that the level of average electric power applied to dissipative loads (6) by an electric energy distribution network is reduced. The supply voltage decrease is detected at the various loads (6) and the average electric power originating from the distribution network and transmitted to the loads, is reduced following such a detection. This momentary decrease can also be used for controlling the scale of charges of the electricity meter of a residence. Thus, average power consumed by the loads (6) supplied by the distribution network can be easily controlled by the electricity production company.

Title: Pedal-operated clutch device.
Inventor: BAUR ERWIN
IPC: F16D25/0638
Filed: 1990-01-31
Abstract: The invention concerns a pedal-operated clutch device (1) for motor vehicles, in particular for agricultural tractors. The clutch (2) is operated entirely by muscle power. Sensitive engagement and disengagement of the clutch (2) combined with easy pedal travel are achieved without external or power-assisted actuation. To this end, a pressure piece (10) of the clutch (2) can be moved against the force of a disk spring (23) in the direction of opening of the clutch (2). According to the invention, the disk spring (23) has a characteristic curve (K) with a negative gradient, and in order to modify the total transmission (i), the pressure piece (10) has a shape which enables the profile of the force to be applied to the clutch pedal (22) to be defined. Preferably the force to be applied to the pedal remains essentially constant, relative to the travel of the clutch pedal (22).
