Abstract: The vocal circuit for a hand tool includes a circuit board, a switch connected with the circuit board, and a chip and a speaker installed on the circuit board. The hand tool may be a gas-burning soldering device including a fuel reservoir, a soldering iron subject to heat caused via burning fuel flowing from a pipe and an igniter received in the shell for igniting the fuel. The switch of the vocal circuit is located between a button of the igniter and a main switch mounted on the shell. The main switch includes a pin extending into the shell for contact with the switch of the vocal circuit and the button of the igniter through the switch of the vocal circuit.

Abstract: Product is conveyed as a continuous stream by a meter conveyor (12) unto a transfer plate (32) and a transfer device (42). The transfer device (42) is movable between a retracted position and an extended position extending over a sweep conveyor (22). In a preferred form, the transfer device (42) is in the form of a thin piece of flexible material and is moved in the conveying direction from the retracted position to the extended position by engaging with the sweep conveyor (22) and is moved to the retracted position by being wrapped around a rotated roller (46). Product is transferred from the transfer device (42) to the sweep conveyor (22) as the transfer device (42) moves from the extended position to the retracted position and is engaged by a metering bar (52ba) which controls the product acceleration on the sweep conveyor (22) to match the meter conveyor (12) until the product group leaves the transfer device (42).

Abstract: A sports guard includes a hollow body having a pad attached to a side thereof. The pad includes a substrate and an outer layer. The substrate includes a first shock absorbing member. A second shock absorbing member is embedded into at least one section of an inner face of the first shock absorbing member. The second shock absorbing member has a shock absorbing capacity greater than that of the first shock absorbing member and is located in a position corresponding to a joint of a user wearing the sports guard. By such an arrangement, transmission of an external impact to the joint is almost impossible.

Abstract: A punch includes a base, a plurality of punch pins, a lever and a plank. The base includes a lower member defining a plurality of holes and an upper member defining a plurality of holes corresponding to the holes defined in the lower member. Each of the punch pins is for insertion through one of the holes defined in the upper member and one of the holes defined in the lower member. The lever is pivotally mounted on the base. The plank defines a plurality of holes. The plank is movably attached to the lever between several positions in each of which it pushes a different set of the punch pins when the lever is operated.

Abstract: A rotational control apparatus (10) includes multiple facings (274-276) rotatable with and axially slideable relative to a mount (124) and which sandwich multiple friction plates (252, 253) rotatable with and axially slideable relative to a hub (12). To create turbulent air flow, the friction plates (252, 253) include an undulating outer circumferential edge (258) and a plurality of passages (260) in the interface portion and overlapping the inner peripheries (282) of the facings (274-276). An automotive clutch release type bearing (290) directly abuts between a piston (40) and the friction facing (274) and is encapsulated in the piston cavity (36) and a cavity (277) formed in the friction facing (274), with the friction facing (274) engaging the axial end (34) of the air chamber (24) when the facings (274-276) and the friction plates (252, 253) are disengaged. In the preferred form, the air chamber (24) and the mount (124) are of the same geometry and are machined from identical castings.

Abstract: An adhesive-resisting skin treatment agent for PVC gloves is produced when the glove mold is soaked in a PVC or PVC polymer and a plastisol to form a film after cooling. The gloves are soaked in a polymer adhesive-resisting treatment solution primarily consisting of chitin, trioctanoin, an aqueous polyester resin and an aerosol mixed in a certain proportion. The capillary and the surface of the film on the gloves can absorb such solution and is evenly coated with a film. Thereafter, the gloves are cooled and their edges are rolled up and detached from the mold. The inner surface of the coating has a protective film and gives a soft, smooth, and comfortable feeling to the wearer's hand when such inner surface is in contact with the hand.

Abstract: An elastic hinge for a notebook computer has an L-like seat secured on a body of the computer, with a hole of which a section is formed as a numeral “8”. A pintle has a first part extending through a barrel, and a second part extending through the hole of the seat. The barrel has two tubular portions for the pintle extending therethrough, and a plate extending from the tubular portions and secured on a monitor of the computer. A torsional spring is provided outside the second part. When a locking member of the computer is released, under the elastic force of the torsional spring, the pintle will be rotated to automatically raise the monitor about an angle of 30° relative to the body of the computer.

Abstract: A nail-driving tool includes a cylinder defining a chamber for reciprocatingly receiving a piston. A bumper is received in the chamber and includes a first bumper section and a second bumper section made of a material having a rigidity different from that of the first bumper section. When in a driving stroke of the piston toward the bumper, air in the chamber exits the cylinder via ports of the cylinder.

Abstract: A belt of nails for nailers includes an outer belt, an inner belt and multiple nails. The outer and inner belts are parallel and respectively have multiple cylindrical outer and inner brackets connected in a straight line with connecting ribs between adjacent brackets. The outer and inner brackets respectively have axial outer and inner nail holes that are aligned. The nails have enlarged heads, shanks and tips. The shanks are mounted respectively through the outer nail holes, and the tips are mounted respectively inside the inner nail holes. Consequently, the outer and the inner belts securely hold the nails so the nailer will roof or nail perfectly.

Abstract: A target throw playing machine includes a main frame, and a throw portion. The throw portion includes a front plate, a plurality of targets, and a plurality of shafts. Each of the targets has a bottom provided with a movable block formed with a cutout and a chamfered portion. Each of the shafts is provided with a plurality of push members each having a first end selectively rested on the chamfered portion of the respective movable block or locked in the cutout of the respective movable block. Thus, the target throw playing machine has an automatically restoring function and has a rotation positioning function.

Abstract: A bicycle rim includes a plurality of elongate slots each of which is composed of a first diameter portion and a second diameter portion which is smaller than the first diameter portion. A tube having threaded outer periphery is inserted in each elongate slot and a core piece is inserted through a passage in the tube. The tube has a flange engaged with an inside of the rim and a cover member covering each elongate slot has a threaded hole for being threadedly connected to the threaded outer periphery of the tube. A protrusion extends from a side of the cover member so as to be engaged with the first diameter portion while the tube is shifted to the second diameter portion. A spoke is inserted in the core piece and threadedly connected to a threaded inner periphery of the core piece.
