Abstract: A multi-functional saw includes a hacksaw assembly and a handsaw assembly. The hacksaw assembly includes a hacksaw handle, a hacksaw blade and a saw bow. The handsaw assembly includes a handsaw handle and a handsaw blade. A connecting portion is provided at a top of the handsaw handle, and the handsaw blade is connected to the connecting portion by a connecting unit. One end of the saw bow is connected to a top of the hacksaw handle, and another end of the saw bow is detachably connected to the connecting portion of the handsaw handle by the connecting unit. The handsaw blade is accommodated in the saw bow when the saw bow connected to the connecting portion. One end of the hacksaw blade is connected to a bottom of the hacksaw handle, and another end of the hacksaw is detachably connected to a bottom of the handsaw handle.

Abstract: A tool is provided. The tool may include a handle, a frame, and a removable saw blade including at least one hole on one end thereof and at least one hole on another end thereof. The tool may also include a compensating clip configured to attach the removable saw blade to the frame and to provide tension for the removable saw blade. The compensating clip may include a plate including a clip hook, and the plate further includes an opening where a compensator spring is provided. The clip hook is configured to attach onto the at least one hole of the removable saw blade to attach the saw blade to the frame.

Abstract: A multi-tool saw assembly includes a saw assembly and a utility tool. The saw assembly includes a frame having a first end and a second end. The saw assembly also includes a first handle fixed relative to the frame. The saw assembly further includes a saw blade, selectively coupled to the frame and extending between the first end and the second end. The saw blade includes a first connection portion connected to the first end and a second connection portion connected to the second end. The utility tool includes a second handle and a work portion. The second handle forms a portion of the frame and/or the first handle. The utility tool is separable from the saw assembly. The saw blade remains connected to the first end and the second end, and the first handle remains connected to the frame, when the utility tool is separated from the saw assembly.

Abstract: A hacksaw having a frame that includes a back handle and an elongated beam that has a series of ridges on at least one or more surfaces of the elongated beam that form a file for reducing and smoothing surfaces of an article. The elongated beam has a first distal end coupled with a first back handle section. A hacksaw blade is coupled with the back handle and a fore piece coupled to a second distal end of the elongated beam.

Abstract: A light weight electric-powered radial saw intended to cut overhead limbs employs a housing having a forwardly direction U-shaped receiving yoke, and a rearwardly directed fitting which receives an elongated handle. An annular saw blade is rotatively supported within the yoke by a plurality of idler rollers journaled to the housing. An electric motor positioned within the housing has a drive shaft that extends in parallel relationship above the saw blade. A drive transmission device such as a gear is interactive between the drive shaft and the saw blade.

Abstract: A combination tool comprising a one-piece thin elongated rigid normally flat blank applied with bends, apertures and incisions thereon, providing a body portion on one end in combination with a right angle extension to a straight oblique handle portion on the other end, the front end of said body portion formed with a reverse bend providing a terminal extended hook furnished with integral means to remove plastic lids, be receptive to a container handle and also perform as a hammer-head, the rear-end of said body portion provided with a right angled bend projected in the opposite direction of said terminal extended hook side and precedes an extension furnished with a bend to said oblique handle portion, the concave side of said body portion's rear-end right angled bend, when faced upward also forms a receptive hook for a container handle, said oblique handle portion furnished with a reverse bend to provide a terminal hook on the same side as said body portion's terminal extended hook, said terminal hook formed

Abstract: A collapsible hand saw has a head portion which has a first receptacle to detachably connect with one end of a frame portion, and a handle portion to fixedly connect with the other end of the frame portion, so as to form a bow shape had saw framework to detachably connect a blade. The head portion has an integrally formed hammer member and a V-shaped notch to substantially drive and pull a nail. In addition, a plurality of spare blades can be mounted with the frame portion between the head portion and the handle portion.

Abstract: This combination tool assembly forms a combination of cutting hand tools including a hatchet, a handsaw and a utility knife configurations with an assortment of interchangeable handsaw blades of different uses and a hatchet handle adapted to enclose the unused handsaw and knife components while the tool is in the hatchet configuration and a handsaw handle forming a cap for the case formed by the hatchet handle and forming a grip for the latter in the hatchet configuration.

Abstract: A system is provided for detecting the presence of an infiltration condition in a line delivering fluid to a patient. Stepping means subjects the fluid in the line to a negative pressure step. The pressure of the fluid is monitored, and processing means then determines whether an infiltration condition is present by determining whether the function of line pressure over time in response to the occurrence of a negative pressure step exhibits a relative slow return to the pre-step pressure, such relatively slow return being characteristic of the presence of infiltration.

Abstract: The invention relates to a multi-purpose tool constituted by a U-shaped frame with two branches joined together by a bar, one branch being extended by an appendix parallel to the bar and equipped at its end with a drilling tool, by a handle assembly extending from the end of the second branch in parallel to the bar and comprising a handle adapted to be either integral with the frame or mounted for rotating thereon, and by an elongated cutting tool with two ends fastenable on the ends of the two branches of the U-shape.The handle comprises a rod of which one threaded end is provided with a shoulder, whereas close to its end, the second branch of the U-shape is provided with a hole traversed by the threaded end of the rod until it contacts the shoulder part, a nut being provided to optionally hold said rod in position on the frame and to selectively immobilize it thereon.The invention finds an application as a tool for drilling an cutting earthenware tiles.
