Abstract: The present invention, in general, describes a refillable writing instrument. The writing instrument may comprise one or more master reservoir, one or more slave reservoir, one or more slave reservoir gate and one or more master reservoir gate. The slave reservoir may have reducing cross-section, facilitating fluid flow towards nib of the writing instrument. The slave reservoir gate may comprise at least one of blocking element, blocking element seat, one or more gates, one or more covers and a combination thereof. The slave reservoir gate provides a connection between the master reservoir and the slave reservoir. Further, the blocking element rests over the blocking element seat due to gravity, restricting return flow of the fluid to the master reservoir. The master reservoir gate facilitates clean, easy and fast refilling of master reservoir using fluid container or fluid nozzle without the need of opening the master reservoir cap.

Abstract: The present invention is a mechanical assembly for single point torque adjustment, an apparatus and method of use of an improved belt for body support and for assisting body during musculoskeletal activities like heavy lifting, kneeling, bending and walking. The belt employs the single point torque adjusting mechanical assembly with an adjustable hinge along with resilient means which stores potential energy when the user alters from a neutral position and may help the body to return to the neutral position. The belt employs structure to share and direct load from head, neck and back to waist and ground. The apparatus may prevent the user from acquiring spondylitis, kyphosis or osteoporosis. The apparatus may be used for users who are subjected to frequent muscular work like bending up and down while carrying heavy loads, sitting too long, walking and the like.
