Abstract:
An actuator (100) for a molding system (900) is disclosed. The actuator (100) includes a linear actuator (102). The linear actuator (102) is configured to move a payload (160) relative to a support structure (170). The linear actuator (102) is connectable to the support structure (170) and the payload (160). The actuator (100) also includes a first compensator (104). The first compensator (104) is configured to compensate for a relative misalignment between the linear actuator (102) and the payload (160). The actuator (100) further includes a second compensator (106). The second compensator (106) is configured to compensate for a relative misalignment between the linear actuator (102) and the support structure (170).
Abstract:
Power actuator (2) device and method for submerged use at petroleum exploitation, where an electric motor (50) drives a displaceable actuating element (16) via a transmission element (80), and where the power actuator (2) comprises at least two parallel and cooperative screw-nut-connections (20) connected to the actuating element (16), and where the transmission elements (80) comprise a driving wheel (40) which synchronically drives a screw (22) or a nut (18) in each of the at least two screw-nut-connections (20).
Abstract:
The invention relates to a mechanism for converting a rotary motion originating from a rotary energy generator (1) into a longitudinal motion of a carriage (25) that is adapted for attachment to a covering, such that said rotary motion will result in a longitudinal displacement of the covering, the mechanism comprising one or more spindle sections (2, 3, 4, 5) drivingly connected at a longitudinal end of at least one of said spindle sections via a gear means (7; 9; 22, 23, 24, 27) to said rotary energy generator (1). The invention further relates to a drive system for coverings comprising mechanisms according to the invention. The invention further relates to a covering system for covering a surface portion such as a window, glass door or the like, of a building.
Abstract:
Medical devices having a platform and an arm movable between a collapsed position and an expanded position. In some embodiments, the platform comprises at least one of a magnetically-attractive material and a material capable of being magnetically- charged. Methods of use.
Abstract:
Die Erfindung betrifft eine Servolenkung (1), insbesondere Hilfskraftlenkung für ein Fahrzeug, mit einer, von einem Servomotor angetriebenen Bewegungsschraube (2) aus einer axial unverschieblich in einem Gestell (3) gelagerten Mutter (4) und einem axial verschiebbaren Bauteil (5) dessen Gewinde (6) mit einem Muttergewinde (7) der Mutter (4) in Eingriff, ist und mit einem Riemenrad (8), das drehfest mit der Mutter (4) verbunden ist und Teil eines Zugmittelgetriebes zwischen dem Servomotor und der Mutter (4) ist, wobei die Mutter (4) mit einem Wälzlager (9) in dem Gestell (3) gelagert ist. Um eine Servolenkung anzugeben, die bei einer einfachen Montage eine geringe Geräuschbildung aufweist und sehr präzise im Betrieb ist, sowie kostengünstig herstellbar ist, ist vorgesehen, dass das Riemenrad (8) aus einem Kunststoff gebildet ist.
Abstract:
The present invention relates to a drive mechanism for a drug delivery device, comprising: a housing (14); an axially displaceable piston rod (22) to act on a piston (18) of a cartridge (16) containing a medicinal product to be dispensed; a drive member (26) threadedly engaged with the piston rod (22) and being slidably disposed relative to the housing (14) between a distal stop position and a proximal stop position, wherein for setting of a dose, the drive member (26) is rotatable with respect to the housing (14); a dose dial member (32) operably engaged with the drive member (26) by means of a reduction gear (28); wherein the drive member (26) at its proximal end section comprises a radially extending receptacle (50) adapted to receive the reduction gear (28).
Abstract:
A gearbox (1) having a housing (2), an actuator (6), a leadscrew (8) rotated by the actuator (6), a rack nut (9) threadingly engaged with the leadscrew (8) to move longitudinally as the leadscrew (8) rotates, a toothed section (12) that moved with the rack nut (9), a shaft (5) and a gear (13) integral with or coupled to the shaft (5), and arranged such that rotation of the gear (13) causes rotation of the shaft (5).
