A power generation apparatus and method comprises at least one gyroglider rotary wing flying at an altitude above the nap of the earth. A strong and flexible tether, connected to the gyroglider frame is pulled with a force generated by the rotary wing. The force is transmitted to a ground station that converts the comparatively linear motion of the tether being pulled upward with a lifting force. The linear motion is transferred to a rotary motion at the ground station to rotate an electrical generator. The tether is retrieved and re-coiled about a drum by controlling the gyroglider to fly down at a speed and lift force that permit recovery of the gyroglider at a substantially reduced amount of retrieval force compared to the lifting force during payout of the tether. Thus, the net difference in force results in a net gain of energy.

A bobbin changing device for feeding bobbins to and/or removing bobbins from a processing device which can wind a strand-form material onto a bobbin and/or from a bobbin, wherein the bobbin changing device has at least one conveyor device, wherein the bobbin changing device has a swivel fork which is suited for feeding bobbins to and/or removing bobbins from such a processing device and for feeding bobbins to and/or removing bobbins from the conveyor device.

The present disclosure relates to a multifunctional retractable puller for pet, which includes a housing, a reel, a ribbon wound on the reel and a zinc alloy hook buckle, a handle integrated with the housing, a handle metal buckle, and a garbage bag device mounted on the metal buckle. The reel-locking key and the reel-opening key of the present disclosure form a switching group. The LED lamp has a function of warning and entertainment, which is convenient for users to warn others when crossing the road at night. The puller has the functions of charging the battery and being charged by the battery, so users do not need to replace the battery. The puller is equipped with a garbage bag device, from which the garbage bag can be taken out at any time, thus facilitating the users dispose of pet excrement at any time.

A rope dispensing system for dispensing a continuous rope from a compressed rope cartridge. The device has a canister for storage of the rope cartridge, a resealable lid with a grommet for passing the rope through the lid, and a replaceable cutting mechanism for cutting the rope. Preferably the rope cartridge is shrink-wrapped to fit within case and keep rope from unraveling.

The present invention is a retractable pet leash with a variable brake system to control a pet. The variable braking system can be engaged or disengaged by the user via 3 methods. The first method is via a handle that is directly connected to the brake. The second method, also actuated by the user is a one touch brake system that uses the rotation of the reel to slowly apply the variable brake over several rotations of the reel. The third method allows the user to set the length of the leash cord and when the set length of the cord is met, engages the one touch brake system. The retractable pet leash provides a system to set the length of the leash cord being let out and ensures that the leash cord is kept taught between the user and the pet and notifies the user when the set length has been reached and applies variable braking in a steady and predictable manner to smoothly stop the pet.

The invention relates to a winch comprising a winding device, which is simply constructed and works very reliably, regardless of the position and orientation of the winch.

The present invention relates to a cable winch, in particular a hoisting gear winch of a hoist, comprising a cable drum, an entry guide for a cable to be wound onto the cable drum, and an actuating drive for adjusting the entry guide relative to the cable drum. The invention also relates to a hoisting device, in particular in the form of a crane, having such a cable winch. According to the invention, a detection unit for detecting an image of the progression of the winding of the cable wound onto the cable drum is provided and the control unit is designed to adjust the entry guide relative to the cable drum depending on the winding progression image captured.

A dynamic tension control system is described herein for driving linear material off a roll in a controlled manner. The dynamic tension control system may include a frame, a shaft for holding a roll of linear material, a motor for driving the shaft, and a dancer tensioning control system for controlling the motor. The dancer tensioning control system may include an actuator assembly through which the linear material passes and a proximity sensor for detecting whether the actuator assembly is proximate to the proximity sensor. When the linear material is pulled from the roll, tension is created in the linear material, which lifts the actuator assembly away from the proximity sensor. The dynamic tension control system may be configured to command, based on detecting that the actuator assembly is not proximate to the proximity sensor, the motor to drive the shaft to unwind linear material from the roll.

A dual retractable badge and key holder apparatus for conveniently securing keys and a badge includes a spool housing having an outer wall, an inner wall, and a sidewall. A median wall is coupled to the sidewall and lies parallel with the outer wall and the inner wall to define an outer cavity and an inner cavity. An axle is coupled to the spool housing. A pair of retractors comprises an outer retractor and an inner retractor coupled to the axle within the outer cavity and the inner cavity, respectively. Each retractor comprises a spool having a spring and a cord wound around the spool. A key ring is coupled to the inner retractor and is configured to secure a plurality of keys. A badge clip is coupled to the outer retractor and configured to secure a badge. A clamp is coupled to the axle adjacent the inner wall.

A handle having a gripping member. A base can be attached to a guidance device worn by an animal A retractable pulley assembly connects the base to the handle. A braking assembly has a trigger and a braking member. The retractable pulley assembly includes a spool, a wheel, an anchor, and a flexible member having a first end and a second end with the flexible member extending from the base to the handle, around the wheel, and to the anchor and with the flexible member being fixedly attached to the spool at the first end and to the anchor at the second end. The trigger actuates the braking member to frictionally engage the flexible member at an intermediate point between the flexible member first end and the flexible member second end to fix the distance between the handle and the base when the flexible member is pulled taut.
