Abstract: A torque output device includes a body with an opening in the top. A top toothed part is located beneath the opening and includes a bore located corresponding to the opening. The top toothed part includes multiple top teeth. A drive shaft secured in the body and includes a central hole in which a rod is located. A driving portion is formed to the lower end of the drive shaft. The drive shaft and the top toothed part are freely rotated relative to each other. A bottom toothed part is mounted to the drive shaft and freely moves up and down relative to the drive shaft. A resilient member is mounted to the drive shaft and biases the bottom toothed part. A pressure collar is threadedly connected to the lower end of the body to set the torque between the engagement of the top and bottom teeth.

Abstract: A method for transaction initiator and recipient to both pre-approve the form and content of a blockchain transaction generates a transaction request by the initiator, and transmits the transaction request to the transaction recipient for verification of the content of the transaction request. The method also signs a digital signature of the transaction recipient on the transaction request if the verification is passed. And a transfer of funds into an account of the transaction recipient can then be made from an account of the transaction initiator. A related system is also disclosed.

Abstract: A photo cutting apparatus includes a support, a press, a linkage and a cutting device. The press is movably mounted on the support. The linkage is for pressing the press. The cutting device is arranged between the support and the press for separating photos developed on a sheet from one another in a single action.

Abstract: A spout and opener includes an opener portion with a sharp tip for opening a pack. The opener portion gets thicker and thicker from the sharp tip in order to fit into the pack tighter and tighter. The spout receives liquid from the pack. The spout portion directs the liquid to the exterior of the pack from the opener portion. The stop extends between the spout portion and the opener portion for avoiding insertion of the whole spout and opener into the pack.

Abstract: A holding and dispensing apparatus is provided for use with a pack. The holding and dispensing apparatus includes a holding device for holding the pack and a dispensing device for dispensing beverage from the pack. The holding device includes a clamp for clamping the pack and a handle attached to the clamp. The clamp includes a first jaw for contact with the top of the pack and a second jaw for contact with the bottom of the pack. The first jaw is connected with the second jaw so that a distance between them is adjustable. Thus, the clamp can clamp packs of different heights. The handle is attached to a plate extending from the second jaw.
