Abstract: A delivery unit (2) of a drug delivery device (1), the delivery unit (2) comprising a subcutaneous delivery mechanism (9) having a subcutaneous delivery member (92), and a subcutaneous delivery member actuation mechanism (10) being operable to move the subcutaneous delivery member (92) between a retracted position and an extended position. The actuation mechanism (10) comprises a rotary member (102) having an engagement member (104) rotatable relative a support member (14), and an actuator (106) comprising a pivot portion (10A) and an engagement portion (10B) pivotally connected to the support member via the pivot portion. The engagement member (104) and engagement portion (10B) are configured to engage upon rotation of the rotary member to pivot the actuator between first and second positions and to thereby move the subcutaneous delivery member (92) between the corresponding retracted and extended positions. In an embodiment, the needle actuation mechanism may comprise a reuse protection.

Abstract: In relation to a sewing machine having a function of rotating a sewing needle in order to prevent occurrence of hitch stitches, there is provided a needle bar that obviates a necessity for an additional rotation mechanism for rotating the sewing needle. A needle bar includes: a needle bar body having a vertically-movable sleeve and a guide bush; a sleeve provided in the needle bar body and having openings, and the like, where balls are to be placed; a cam shaft that has a disc-shaped portion which is provided in the needle bar body, an upper shaft which is provided with a pair of grooves or the like having helical grooves and which is inserted in the sleeve, and a lower shaft which is formed so as to protrude downward from a guide bush; and a joint secured to the lower shaft for securing a sewing needle.

Abstract: A crank adjusted shifting mechanism having a servo driven eccentric in communication with a drive rod and optional clamping assembly provides for a fast and programmable needle bar shifting mechanism for a tufting machine.

Abstract: A stitching tool including a needle including an arcuate shank having an arcuate length extending from a needle point at one end thereof to another end, called a suture end, and wherein the needle is toothed along at least a portion of the length.

Abstract: A hand-held mending gun for tufting stitches into a backing material has a hollow needle reciprocally driven axially to form stitches in a backing material. A drive mechanism couples a rotary motor to a needle carrier for reciprocation along the axis of the needle. A yarn feed roll connected to a yarn drive disk may be selectively changed in speed by changing the position of the yarn feed disk relative to a radius of a drive disk through a pneumatic cylinder having a piston relocatable between an extended and a retracted position. With the speed of rotation of the drive disk constant, the speed of the yarn feed roll may be changed between a high and a low pile height setting, or position, by changing the distance of a contact point of the yarn feed disk on the drive disk from the center of the disk drive. A pneumatic selector switch allows a single operator to control the selection of the high or low pile height position.
