  • Publication number: 20240305039
    Abstract: A strain relief device. The strain relief device includes: a lamella element with a base element with a through-opening, set up for feeding through a strand-shaped element substantially parallel to an axial direction, and a lamella which projects from the base element along the axial direction; a clamping body, annular in shape and arranged rotatably on the lamella element radially outside the lamella; wherein the lamella, in a front portion facing away from the base element, is ramp-shaped on its outer side facing the clamping body in the direction of rotation, with a distance to the through-opening that increases along the direction of rotation, and the clamping body has at least one projection projecting radially inward, couples with the front portion of the lamella when there is a rotation of the clamping body and displaces the lamella in a direction away from the clamping body.

  • Patent number: 10823233
    Abstract: An overload protection assembly includes a first gear of a servo, a second gear of the servo, defining a receiving space; and a clutch configured to coaxially couple the first gear to the second gear and transmit torque between the first gear and the second gear. The clutch includes an elastic member arranged around the first gear and received in the receiving space. The elastic member includes a number of protrusions at a circumferential surface thereof, and a number of recesses are defined in a lateral surface of the receiving space. The protrusions are used to be respectively engaged with corresponding ones of the recesses so as to couple the firs gear to the second gear when a value of the torque is less than a preset value, and disengageable from the corresponding ones of the recesses so as to disconnect the first gear.

  • Patent number: 10092568
    Abstract: Provided are: methods for treating aging or an age-related condition, symptom or disease; methods for stimulating hair growth, regrowth or pigmentation (or preventing hair loss); methods for increasing the expression of an adenosine receptor in dermal cells (in combination with hair growth); methods for treating a condition or disease of the skin or at least one symptom thereof, including cosmetic treatment (e.g., wrinkles, hyperpigmentation, redness, rosacea, dryness, cracking, loss of firmness, loss of elasticity, thinning, and loss of vibrance). The methods comprise administering a sufficient amount of a CBP/catenin (e.g., CBP/?-catenin) antagonist as disclosed, and particularly wherein administration is in an amount and manner sufficient to provide for increasing the number of asymmetric renewing divisions relative to, or at the expense of symmetric divisions in relevant somatic stem cell population. In particular aspects, the CBP/catenin (e.g.

  • Patent number: 9371330
    Abstract: Provided are: composition and methods for: treating aging or an age-related condition, symptom or disease; stimulating hair growth, regrowth or pigmentation (or preventing hair loss); for increasing adenosine receptor expression in dermal cells (in combination with hair growth); for treating a condition or disease of the skin or at least one symptom thereof, including cosmetic treatment (e.g., wrinkles, hyperpigmentation, redness, rosacea, dryness, cracking, loss of firmness, loss of elasticity, thinning, and loss of vibrancy). The methods comprise administering a sufficient amount of the disclosed CBP/catenin (e.g., CBP/(?-catenin) antagonist compositions, and particularly wherein administration is in an amount and manner sufficient to provide for increasing the number of asymmetric renewing divisions relative to, or at the expense of symmetric divisions in relevant somatic stem cell population. In particular aspects, the CBP/catenin (e.g.
