Abstract: A rotating bi-directional pneumatic gun has a body and a guiding tube mounted rotatably in the body. The guiding tube has an outer surface, a front notch, a rear notch, a front groove and a rear groove. The front notch and the rear notch are defined longitudinally in the outer surface of the guiding tube and are kept from communicating with each other. The front groove and the rear groove communicate respectively with the front notch and the rear notch and each have multiple inclined bores extending respectively toward the front end and the rear end of the barrel. Rotating the guiding tube can change the direction of air flow of the pneumatic gun, and the rotating bi-directional pneumatic gun is convenient to operate and easy to assemble.

Abstract: The tire pressure gauge has a body, a controller and a cap. The body has a valve stem connector that attaches to a valve stem of a tire to sample internal air pressure of the tire. The controller is mounted inside the body and includes a microprocessor, a pressure sensor, an alarm unit and a pressure indicator. The microprocessor stores a preset pressure value. The pressure sensor senses the tire's internal air pressure sampled by the valve stem connector, generates an electronic signal indicating the sensed pressure and sends the electronic signal to the microprocessor. The microprocessor compares the electronic signal to the preset pressure value. If the electronic signal is lower than the preset pressure value, the microprocessor activates the alarm unit that produces an audible warning.

Abstract: A filter assembly for a pneumatic tool has an inner housing, a cover, an inner tube and a connecting post. The cover is attached to the inner housing and has a connecting portion and at least one air passage. The connecting portion has an inner space. The at least one air passage communicates with the inner space in the connecting portion. The inner tube is mounted inside the inner housing and defines an annular space between the inner tube and the inner housing to hold filters and/or drying agents inside and communicating with the at least one air passage. The connecting post extends into the inner tube, is detachably connected with the cover and has an air channel and multiple discharging holes. The discharging holes communicate with the air channel in the connecting post and the annular space between the inner tube and the inner housing.

Abstract: A wireless network transmission device is disclosed. A network control chip, a communication control chip and a control chip set are arranged in parallel. The network control chip, communication control chip, and control chip set are connected to the first module and the second module through a bus. The first module is connected to an external network communication protocol module and the second module is connected an external mobile phone communication protocol module. Thus, the system is communicable with network communication protocol module and mobile phone communication protocol module in parallel; thereby, data of different protocols being transmitted in one device. The control chip set serves to connect a PCMCIA interface to the first module and second module through the network control chip and the communication control chip.

Abstract: An air gun with a quick-releasing device has a body, a head tube attached to the body and a detachably functional tip, wherein the quick-releasing device is attached to a distal end of the head tube to secure the detachably functional tip. The quick-releasing device has a slit defined in the distal end of the head tube to communicate with an inner space of the head tube, a locking sheet movably received inside the slit to partially enter the inner space of the head tube, and a locking lever pivotally mounted on the head tube to drive the locking sheet to move in a vertical direction. Thereby, the locking sheet is allowed to leave the inner space of the head tube when a user presses the locking lever to enable easy release of the attached functional tip and then to exchange the original tip for another functional tip.

Abstract: Method and material for manufacturing cold/hot elastic gel, in which synthesized vegetal glue and high order starch are mixed at a certain ratio and fully stirred into an even state. Then a certain amount of water is added into the mixture and stirred to an even state to produce flour mash-like sticky mass by various processing tools or human hands. The solution is at the same time heated to a certain temperature. During heating, the chemical bonds of the molecules of the materials are chemically changed to form thermally irreversible gel. The materials are blended into flour mash-like sticky mass. After rested and cooled, the sticky mass processed by various processing measures into gel foods which can be frozen and refrigerated. The elasticity of the gel foods in hot state is equal to the elasticity of the gel in cold state. The gel foods can be further steamed or cooked for eating.

Abstract: A bi-directional compressed air outlet includes a tubular body having a handle which has a chamber and a passage defined therein, and a valve device disposed to the handle and communicating between the chamber and the passage. A middle member is movably received in the body and has a plurality of inclined apertures defined therethrough. The body has an annular inclined flange defined in an inner periphery thereof and the middle member has an annular inclined surface defined in a front end thereof so as to mate with the inclined flange. Air in the chamber proceeds through the passage and selectably toward a front end of the body via a space defined between the inclined flange and the inclined surface, or a rear end of the body via the inclined apertures.

Abstract: An adjustable illuminating/retrieving apparatus comprising a flexible structure having a first end portion and a second end portion connected with a first end portion of an extension tube which includes a second end portion with a magnet fixedly mounted therein. A supporting base extends outward from the first end portion of the extension tube and is pivotally connected with a pivot base. A receiving tube includes a first end portion mounted on the pivot base and a second end portion formed with a first annular flange extending outward. A lighting unit is received in the receiving tube and partially extends outward of the second end portion of the receiving tube. A sliding sleeve is slidably mounted on the receiving tube and includes a first end portion formed with a second annular flange extending inward.
