Abstract: A rotational control apparatus (10) includes multiple facings (274-276) which sandwich multiple friction plates (252, 253) rotatable with. 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 and is encapsulated in the piston cavity (36) and a cavity (36) of a piston 40 and a cavity (277) formed in the friction facing (274). The friction facing (274) engages the axial end (34) of the air chamber (24) and in alternate form, a friction facing (300) of the piston (40) interfaces with an interface surface (318) intergrally formed on the hub (12) to control rotation of the hub (12) when the facings (274-276) and the friction plates (252, 253) are disengaged.

Abstract: A folding chair includes two pairs of intersected legs. A traverse pivot rail interconnects the intersections of the two pairs of legs. Two support mechanisms are spaced along the pivot rail, each support mechanism comprising an upper hole. Two cylinder pads are anchored in the upper holes. Two fastening mechanisms each include an upper section and a lower section, each section having a half tube mating and coupled to each other with the pivot rail passed therethrough. A seat is pivotably secured to the pivot rail by fasteners threaded through the upper and the lower sections and into the seat. In a use position, the seat is adapted to exhibit an elastic, downward movement as buffered by the cylinder pads. In a folding operation, the seat is turned about the pivot rail until being stopped by a chair back.

Abstract: A laminate forming process includes installing a heater assembly in a processing chamber, the heater assembly having a lower diffusion screen; coupling a vacuum assembly to channels of a platform; conveying layers of titanium and solid adhesive at room temperature onto a workpiece on the platform heating the processing chamber to a predetermined temperature by the heater assembly through the diffusion screen for evenly applying heat to the layers of titanium and adhesive and the workpiece and melting the layer of adhesive; and activating the vacuum assembly for sucking the layers of titanium and adhesive onto the workpiece through a communication of the channels so as to secure the layers of titanium and adhesive onto the workpiece and smooth the layer of titanium.

Abstract: An electrical generator includes a coil, a coil seat and a set of permanent magnets. The coil and the set of permanent magnets are separated from each other. The coil is mounted in the coil seat so that either the coil or the set of permanent magnets can rotate relative to the other. The set of permanent magnets has multiple north poles and south poles arranged alternately. The set of permanent magnets is adjustably positioned relative to the coil seat. The set of permanent magnets is maintained a distance from the coil seat and induces a voltage in the coil in the coil seat when the set of permanent magnets rotates relative to the coil.

Abstract: A coffeepot comprises a body, a handle assembly, a lid connecting assembly, a discharge control assembly, a check valve, a disc-shaped abutment assembly, a push member, and a disc-shaped lid. In a closed state of the check valve, press the push member to lower the discharge control assembly a distance with a spring of the discharge control assembly being compressed, a gap is formed between a base of the discharge control assembly and the lid connecting assembly, a coffee discharge passageway is formed from the gap to a spout through a passageway of the lid connecting assembly, and tilt the body will pour coffee out of the spout via the coffee discharge passageway. Further, in an open state of the check valve, releasing the push member will close the coffee discharge passageway.

Abstract: A wrench includes a head and a handle extending from the head in a direction. The head includes two jaws extending from the head in an opposite direction and a throat formed between the jaws. Each of the jaws includes a contact surface for contact with a facet of a head of a bolt. The contact surface of at least one of the jaws includes a plurality of teeth. The throat defines a central recess for receiving a corner of the head of the bolt. The head may define a recess between the throat and each of the jaws. The throat may include two flat contact surfaces for contact with two adjacent facets of the head of the bolt. The central recess defined in the throat is positioned between the flat contact surfaces of the throat.

Abstract: An inflatable bed has a primary bed and a supporting rim securely connected to an outer contour of the primary bed. The primary bed has an extension integrally extending from sides of the primary bed to securely engage with an outer surface of the supporting rim so as to limit movement of the supporting rim. After a load is placed on top of the primary bed, the overall appearance of the inflatable bed is maintained and the movement of the supporting rim is limited.

Abstract: A wrench includes a rod, a retainer, a pressing member, and a casing for receiving the retainer and the pressing member. The rod includes a driving portion on an end thereof for engaging with a fastener. The retainer has a central portion securely mount to the rod to turn therewith. The pressing member is turned together with the casing when the casing is turned. The pressing member has at least one engaging member that is biased to selectively engage with one of plural retaining sections of the retainer, thereby exerting an engaging force between each of the ends of the pressing member and an associated one of the retaining sections of the retainer. When a rotational force applied to the casing is smaller than the engaging force, the retainer and the rod are turned to thereby turn the fastener.

Abstract: An eddy flow generator includes a base adapted to be located at a joint between the fuel injector and the intake manifold and multiple passages each being adapted to correspond to and communicate with one of multiple air paths of the intake manifold. Each passage has multiple spirally formed blades to direct air flow in a spiral pattern. Therefore, air coming from the intake manifold is able to fully mix with fuel via movement of the air in a spiral pattern.

Abstract: A light emitting tooth brush having whitening and sterilizing effects includes a handle having one end provided with a light permeable brush head, a control switch mounted in the handle, and a circuit board mounted in the brush head. The circuit board is electrically connected to the control switch, and is provided with a light emitting member which may emit optical waves having a specified wavelength through the light permeable brush head. Thus, the light emitting tooth brush may achieve the sterilizing effect and may achieve the effect of cleaning and whitening the user's teeth.

Abstract: A wrench includes a rod, a retainer, and a casing for accommodating the retainer and allowing relative rotational movement between the casing and the retainer. The rod includes a driving portion on an end thereof for engaging with a fastener. The retainer has a central portion securely mounted to the rod to turn therewith. At least one engaging member is mounted in the casing and biased to selectively engage with one of plural retaining sections of the retainer, thereby exerting an engaging force between the engaging member and an associated retaining section of the retainer. When a rotational force applied to the casing is smaller than the engaging force, the retainer and the rod are turned to thereby turn the fastener. When the rotational force applied to the casing is greater than the engaging force, the casing slides while the retainer and the rod are not turned.

Abstract: A tool assembly includes a main body having two sidewalls. Two sets of tools are, respectively, rotatably mounted between first ends and second ends of the sidewalls. Each sidewall has an outwardly facing recessed section for detachably receiving a tire repairing tool in the preferred form of a tire lever. Tire patches are received in at least one of the tire levers for proceeding with tire patching when required. At least one of the tire levers includes a driving column for adjusting the bolts to which the tools are rotatably mounted. The tools include a chain repairer that may engage with the driving column of the tire lever for proceeding with chain repair.
