Abstract:
According to the invention, the portable terminal comprises a central unit (1), a keyboard (2) and a screen (3). The keyboard (2) can be disconnected, whereas the screen (3) is connected to the central unit (1) by means of a hinge device operating at least one bent lever (22), of which one end is hinged onto a first side of the central unit (1), while the other end is hinged onto the screen (3). On account of the bent shape of the lever, the screen may be tilted against a second side of the central unit (1). The terminal, according to the invention, can consist of a microcomputer.
Abstract:
The proximity detector includes a probe (4) and a printed circuit (3), contained within a case (33) which is closed by a lower cap. A plug (35) with connection pins (36) running through it, closes off the other end of the case. Said plug (35) also includes a filling funnel (13) allowing through a resin which can be hardened and which is able to enter once the container has undergone centrifugation. Said resin forces the air out through interstices (i3) which the resin itself cannot penetrate. During this operation, the funnel is held sealed between elastomer parts belonging to two centrifuging rotor elements which define a recess for the apparatus. Application: faster and more efficient filling.
Abstract:
Detector comprising a sensor and a processing circuit connected to a load by means of two wires. Two switches (I1, I2) are arranged in series in a switching circuit leg (21), the ends of which (C, D) are connected to the detector terminals and the middle point (S) to a terminal (F) of the processing circuit. When operating (I1) is conductive and (I2) determines a parallel regulation of the voltage (V) at the processing circuit (12) terminals; when in rest position, (I1) determines a series regulation of the voltage, while (I2) is blocked.
Abstract:
Output control circuit for a programmable logic controller, comprising a control unit (13) and a circuit (14) for controlling and checking output channels (11), including a deserializing section (16). The output circuit receives descending frames (T1) and ascending frames (T2) and, according to its configuration, it returnsascending frame (T3) to the control unit produced from frames (T1) and/or (T2).
Abstract:
The device includes, on the one hand, a main body with a base (2) and, on the other hand, screen-type dialogue means (7) which are placed in a flat casing connected to the main body (2) by support means and means for maintaining the angular position (14) which can be regulated both for height and for angle. Said means for maintaining the angular position (14) are arranged coaxially to a pivoting axis XX' of a support arm (15) on the body (2) and include a free-wheel device mechanically located in series with a friction angular coupling device. The invention makes it considerably easier to adjust the position of the dialogue means.
Abstract:
The method for the determination of a spring from values of certain parameters of the spring selected from a predetermined set of functional and dimensional parameters is implemented using a computer. The method includes the following steps: (10) definition of said selected parameters and input of the values of said parameters; (50) initial checking of consistency between the parameter values entered at the definition and input step; (60) control of the sufficiency of the selected parameters defined at the definition and input step; (70) computation of the parameter values needed for manufacture of the spring; and (80) second checking of the consistency between the parameter values entered and computed.
Abstract:
A base (10) integral with a barrel (4) which traverses the opening (6) carries a lever (16) with two branches (17, 18) of which an opposite side (24) is hinged in an extension (30a) and whose extremity ridges bear against the back face (12) of the panel (7). A single screw (35) allows to control the pivoting motion of the lever (16) towards the panel. Application to the fixing of control and/or signalling apparatuses in openings of electric installation panels.
Abstract:
The process disclosed is appliable to transmission of data of the multiplexed series type between entities capable of emitting or receiving data, to or from the line. Each entity connected to the line can access all the data flowing in the line, and all the exchanged data are modeled by a distributed database which is updated and maintained by the fact that each entity stores and updates a local copy of the corresponding useful part of the database it contains. Each time an entity is placed in service, a coherence check is carried out to ensure that the emitting and consuming entities interpret data in the same way. The coherence check is carried out by a protocol without prior contact or acknowledgement.
Abstract:
The disclosed circuit breaker has two make and break control buttons. The make button (14) and the break button (13) are pivotingly mounted in the casing of the breaker and present, in front of view, a height difference (h) of their lower ends (20b, 20b'). Their upper ends (20a, 20a') clear and conceal alternately the display elements (32, 32') provided on the front face (17) of the casing.
Abstract:
The breaking structure for a circuit breaker according to the invention comprises, for each pole, a contact bridge (17) housed in a pusher (20). The pusher is guided in a fixed cage (21) monted in the casing of the circuit breaker, the cage being provided with windows (24) for the contact bridge and with a high stop (26) for the bridge , so as to form a telescopic sub-assembly.
