IPC: A47C3/30
Filed: 1988-01-07
Abstract: An hydraulic strut is formed as a piston and cylinder assembly (1, 2) having a first, larger diameter piston (8) working in a larger diameter cylinder bore portion (6) to define a first hydraulic chamber (12) around the piston rod (4), and a second, smaller diameter piston (9) also secured to the piston rod (4) and working in a smaller diameter bore portion (7) of the cylinder assembly (1) to define a second hydraulic chamber (14) between the second piston (9) and the adjacent end (15) of the cylinder assembly. The two chambers (12) and (14) are connected together by a passage means (16, 23) controlled by a valve (17), and the pressure-effective areas of the chambers (12) and (14) are made equal such that the expansion of one chamber is equal to the contraction of the other chamber during adjustment of the length of the piston and cylinder assembly.

Abstract: The hand valves, such as, for example, closing valves (14) or reducing valves (13, 16), can be bridged via a bypass line (47) by the actuation of a directional valve (24, 33). The pressure drives (10, 18) for actuating the rollers can thereby be controlled either manually on the spot or by remote control. An electropneumatic pressure-regulating valve can be incorporated in the bypass line, so that the desired operating pressure can also be controlled remotely. The control and supervision of the installation are thereby substantially simplified, without the possibility of manual actuation of each individual pressure drive being lost. <IMAGE>

Abstract: Une lentille ophtalmique améliorée (50) comprend plusieurs zones de puissance alternées caractérisées par une puissance qui varie continuellement dans chaque zone et qui est en transition d'une zone à l'autre. Autrement dit, sont prévues plusieurs zones concentriques (au nombre de deux au moins), dans lesquelles la variation entre une correction de vision rapprochée et une correction de vision lointaine est continue, c'est-à-dire que cette variation passe d'une puissance focale à correction rapprochée (60) à une puissance focale à correction lointaine (58), puis retourne à une correction rapprochée pour revenir de nouveau à une correction lointaine ou vice versa. Ce changement s'effectue en continu (progressivement), sans changements de correction brusques ou à-coups. Dans une première variante, la variation de puissance alternée continue est réalisée pour une courbure à changement continu de la surface postérieure de la lentille, ce qui modifie l'angle d'impact des rayons lumineux arrivant sur l'oeil. Dans une seconde variante, la variation de puissance alternée continue est réalisée par la création de caractéristiques non homogènes de la surface, dont la matière présente des indices de réfraction qui varient continuellement dans la direction radiale de la lentille (c'est-à-dire lorqu'on s'éloigne de l'axe optique).

Abstract: In counter circuitry, for example a motor rotation speed control circuit fabricated in an LSI, a first counter (10), after being reset upon each rotation of the motor, resumes counting clock pulses (CLOCK). Bit-outputs of the first counter (10) are led out of the LSI package and are selectively connected to led-out input terminals of at least one AND gate (18, 12), each of which detects counting, by the first counter (10), of a count-number determined by the sum of the count numbers designated by bit-outputs of the first counter connected to the AND gate. One AND gate (18) detects a first reference count-number N a , which is smaller than a probable least count-number corresponding to, for example, a lower limit of tolerance of motor speed, even taking into consideration possible future changes of the desired motor speed. After being reset upon detection of N a , a second counter (22), preset with a second reference count-number N b , starts to count the clock pulses. N b  is chosen so that N a  + N b  = N₀, N₀ being a target count-number corresponding to a target cycle time of a single motor rotation. A carry signal from the second counter (22) can be used instead of a signal indicating a count of N₀ clock pulses by the first counter (10), even when motor rotation is faster than the target speed. If motor speed has to be modified, the count-­numbers for detection can easily be modified by changing the external connections of the led-out terminals. The fixed count-number of the second counter (22) eliminates the need to lead out connections for presetting the second counter, resulting in reduced size and cost of the LSI package.
