Abstract: A combination system of fixed arbor hole saws and quick-change mandrel that enables a user to drill multiple of same sized or different sized holes in desired substrate in a quick and hassle-free manner. A drill bit held and retained in the quick-change mandrel serves as a common pilot for all different fixed arbor hole saws. The combo system requires a single common quick lock mandrel that positively locks a hole saw on insertion. The securely locked hole saw can be released with easy pull on a collar in the mandrel. Also, the cut-out slug of any substrate is very easy to remove once the hole saw is released from the mandrel.

Abstract: A bit holder has a shank at a proximal end thereof and a blind bit-accepting hole at a distal end thereof, shaped to receive a correspondingly-shaped tool bit. The bit holder has at least one locking mechanism comprising an opening defined in the bit holder, opening into a side of the bit-accepting hole. A locking element in the opening is moveable towards the opening to contact a tool bit in the bit-accepting hole. The bit holder has a sleeve around a body portion of the bit holder, overlying the opening and biased by a spring towards a normal position. The sleeve has an internal ramp angled to contact the locking element to urge the locking element towards the tool bit as the sleeve is moved into the normal position, and to accommodate the locking element when the sleeve is moved from the normal position against the force of the spring.

Abstract: A power tool with an auxiliary handle which is easily securable to and removable from the tool. The auxiliary handle provides additional functionality, beyond being merely a handle. The auxiliary handle is detachably engaged to the power tool for working as a side handle via a “quick-connect” mechanism, which locks the handle in place either automatically or with a simple movement, and which can be released by a simple movement. The handle also serves a secondary function. For example, its quick-connect mechanism can be so configured as to receive a screwdriver bit. When removed from the power tool, the handle can act as a screwdriver handle. The handle may include compartments or slots to retain a variety of screwdriver bits or other components. The handle could be a screwdriver with auto lock bit or bit holder.

Abstract: Disclosed is a device for clarifying and enhancing liquid for improved luring of insects. The device comprises a segregator for collecting eggs and larvae present in the liquid and a unit for receiving an additive and releasing the additive into the liquid passing through the segregator. The additive may be an insect attractant or luring substance, dye of cleaner. Also disclosed is an apparatus for reducing populations of aquatically hatched insects comprising the device.

Abstract: A container is combined with a base having insect combating features, i.e. for trapping and/or poisoning of insects, preferably but not necessarily combined with insect attracting elements. In particular, the container may be a waste basket, and the targeted insects may be bed bugs, and/or roaches, and/or ants. The assembly has a container portion and a base portion. The interior of the base portion is accessible by insects via one or more small gaps or openings, and contains the trapping and/or poisoning elements, which may include a replaceable glue strip or the like. Preferably, the assembly is also be provided with insect attracting means, which may include chemical attractants, carbon dioxide generation, and/or heat. In some embodiments, separate areas may be provided to combat different insects.

Abstract: A bit holder has a shank at a proximal end thereof and a blind bit-accepting hole at a distal end thereof, shaped to receive a correspondingly-shaped tool bit. The bit holder has at least one locking mechanism which includes an angled path defined in the bit holder, opening into a side of the bit-accepting hole, extending away from the bit-accepting hole in a proximal direction at an acute angle A from a central axis. A locking element is slideable in the path. A sleeve around the shank is biased towards the bit-accepting hole by a spring, such that a distal end of the locking element extends slightly into the bit-accepting hole. Moving the sleeve towards the proximal end of the bit holder retracts the locking element from the bit-accepting hole, thereby releasing the bit. A spring-loaded plunger in the blind hole may be used to eject the bit automatically when the locking mechanism is released by the sleeve.

Abstract: A bed bug trap (2) is combined with a conventional power bar (1). Bed bugs can enter the trap via a small gap (6) between the power bar portion and the bed bug trap, where they then fall off a small precipice (14) and onto a glue strip (4, 5) or the like. The assembly can be easily opened for inspection and replacement of glue cartridges (5). Attractants (7, 17, 13) can be provided, including heat via a small heating element (7), chemical attractants (17), and carbon dioxide via a carbon dioxide generator (13). The assembly can be adapted for use with other insects, or an additional trap (91, 92; 110) can be attached for other insects.

Abstract: A flange making process, includes synchronized press to process the hot sheet metal right coming out of hot rolling mill. The hot rolling mill could have impression forms for pressing flange forms on hot metal sheet. This process could eliminate the consume of steel and energy. The flange could have a protrusion around the central hole. With this protrusion, it can move weld away from sealing surface and decrease deforming and leakage of the interface. The flange could be used on a flange assembly, wherein one of the pipe is extended to another pipe. It can improve the sealing the joint of the flange assembly.

Abstract: An impact driver accessory, having a work portion and a shank, the shank has an axial hole at a distal end and the work portion has an engagement portion, the engagement portion is inserted in the axial hole and is secured in the axial hole, wherein there is a non-filled tubular section in the shank; A method of manufacturing an impact driver accessory, includes following steps, forming an axial hole at a distal end of the shank of a suitable length and inserting the engagement of the work portion in the axial hole and securing the engagement in the hole by one or more of a variety of mechanical mean, wherein there is a non-filled tubular section since the depth of the axial hole is longer than the length of the engagement of the work portion. The non-filled tubular section is serving as an torsion zone to withstand the large torsion.

Abstract: A bed bug trap includes heat, carbon dioxide and/or semiochemicals (pheromones and/or kairomones), to attract and trap bed bugs. The trap may be combined with the appearance and/or function of another appliance, such as an air freshener. The release of semiochemicals may be combined with the release of air freshening compositions. The device preferably is powered, but not necessarily. The bed bug trap may provide one attraction mode, or two attraction modes, namely one which uses heat, carbon dioxide and/or kairomones to attact bed bugs seeking a meal, and the other which uses pheromones to attract bed bugs seeking a safe harbor, i.e. a hiding place. The two different modes may operating simultaneously in different areas, or the trap may be switchable between modes, for example via a timer, or in response to some trigger such as a light sensor.
