Patent EP-0190469-A1 (EP)
Inventor: VAN MIL JOB FRANCISCUS PETRUS
IPC: H03F3/45
Filed: 1985-12-13
Abstract: If in integrated filter circuits comprising transconductors and capacitors transconductance amplifiers with comparatively low transconductances are employed, only comparatively small capacitors need to be integrated. A transconductance amplifier with a comparatively low transconductance comprises a first transistor (T 1 ) and a second transistor (T 2 ), which are arranged as a differential pair and whose com- moned emitters (3) are connected to a current source (4). An input voltage (v i ) is applied between the bases of the first transistor and the second transistor (T,, T 2 ). The collector current (I 1 ) of the first transistor (T 1 ) is applied to a current dividing circuit (9), which divides this current in a ratio 1:a into a first current (1 3 ) and a second current (I 4 ). Similarly, the collector current (1 2 ) of the second transistor (T 2 ) is divided in a ratio 1:a into a third current (1 5 ) and a fourth current (I 6 ). The fourth current (I 6 ) and the first current (1 3 ) constitute the first output current (1 7 ) and the second current (1 4 ) and the third current (1 3 ) constitute the second output current (I 8 ).

Abstract: The laminated product (2) formed by alternated piling of glass sheets and thermoplastic sheets is placed on a conveyor belt (1) with indexed feed. In position (2), the laminated product is heated by dielectric losses between the plates (3a and 3b), connected to the generator (4). In position (2'), the laminated product is clamped between the jack plates (5a and 5b) of which the sides facing each other are lined with soft walls sealingly secured by their edges. Pressure air is introduced through conduits such as (5c) between the jack plate (5a, 5b) and its soft wall. The progressive inflation bulges the soft walls, and the clamping area of the laminated product (2') is progressively developed from the center towards the edges, while expelling air imprisoned in the laminated product (2'). After solidification of the thermal plastic material, the laminated product (2") is unloaded.

Abstract: On connaît depuis 1970 des volants de matériaux en fibres (par exemple, verre, polyaramide) qui ont certains avantages par rapport aux volants en acier, par exemple une densité d'énergie plus grande et un comportement à l'éclatement pratiquement sans danger. Jusqu'à présent, les volants obtenus par bobinage de fibres furent fabriqués exclusivement à partir de monofilaments enrobés d'une matrice synthétique (par exemple, la résine époxyde). Cette opération d'enroulement est compliquée et exige, entre autres, un guidage précis des filaments. Pour obtenir le volant selon l'invention, une bande de tissu de filament (par exemple verre, polyaramide) est enroulée avec précontrainte sur un moyeu. La précontrainte est modifiée en fonction du rayon d'enroulement qui augmente. Les couches d'enroulement sont imprégnées d'une résine synthétique (par exemple, résine époxyde) pour leur fixation. Après achèvement de l'enroulement, le volant est durci en le tournant et en amenant de la chaleur sous vide. Le coût de l'enroulement et aussi du volant terminé obtenu à partir d'une bande de tissu en filaments est considérablement diminué par rapport aux volants en monofilaments.

Abstract: The present invention relates to a process for controlling the movements of a vehicle-mounted ladder, particularly a rescue and firefighting ladder, comprising a ladder formed from a plurality of elements capable of being extended or retracted by means of an actuator and of being raised by pivoting about a substantially horizontal axis by the agency of an actuator and being oriented about a substantially vertical axis by the agency of an actuator, and an electronic microprocessor system receiving at its input the signals from a control desk equipped with manual raising/lowering, extension/retraction and orientation control members and the signals representing the effective load exerted on the ladder, the developed length and the angle of orientation and generating at its output signals serving for controlling the actuators. The method according to the invention is characterised in that it involves calculating from the signals of the sensors a first speed coefficient which is a decreasing function of the developed length of the ladder, a second coefficient which is a decreasing function of the effective load and a third coefficient which is a decreasing function of the slewing radius of the ladder, calculating a maximum raising/lowering speed value from a maximum speed value adapted to the minimum developed length and to the minimum effective load and weighted by the first and second coefficients, calculating a maximum orientation speed value from a maximum value adapted to the minimum slewing radius and to the minimum effective load and weighted by the second and third coefficients, and supplying to the actuators control signals which do not exceed the maximum values thus calculated. <IMAGE>
