Input transducers include sensors which report the status of the colonies including colony weight, temperature, and relative humidity. A bee counter can also be included in the system to indicate colony activity. A bee counter is disclosed which uses an amplifying, multiplexer hysteresis and debounce circuitry to enable rapid and accurate polling of a single passageway. Information collected can be retrieved by read-out or liquid crystal display. Alternatively, information ca be retrieved by telephone line or wireless communications. The bee monitoring system also can remotely control peripheral devices such as feeders or chemical samplers.

The invention discloses a method and a protection device for reducing object impulsion, and relates to the field of object collision protection technology. The method and the device are characterized in that: when an external force is exerted on an object, a liquid-filled main cavity of the protection device positioned on the stressed surface of the object is exerted by the external force and a preset value is reached, films of different levels break in a passive or active manner to make the fluid flows into a vacuum cavity arranged around the main cavity; the external force exerted on the object is dispersed and the collision rebound is eliminated by the flowing of the fluid, thereby achieving the purpose of effectively preventing damages on the object to be protected. The brand new protection method and the protection device have wide application prospect.

A bottle and accessories carrier generally includes a bottle carrier with preferable accessory storage. One version includes a holster portion for retaining at least one bottle or container; straps or other means attaching the holster portion onto a user's body or other article; a preferably flattened bottle; and an accessory storage area for carrying items.

The invention provides a cutting machine provided with a cutting and clamping device. The cutting machine provided with the cutting and clamping device can prevent the bounce of a bar in cutting, thereby improving the cutting precision. The cutting machine provided with the cutting and clamping device is provided with a fixing cutter (5) and a movable cutter (6) cutting a delivered bar (7) and utilizes the shear force of the fixed cutter and the movable cutter to cut off the bar. A base is arranged on the cutting machine is a dismountable manner. The fixed cutter (5) having a cutter part (5a) capable of reversing for charging and the movable cutter (6) moving relatively to the fixed cutter are arranged on the base. A press component (12) is arranged to dispose in a position opposite to the fixed cutter over the bar. The press component (12) is used for pressing an opposite side of a fixed cutter side of the bar when cutting the bar. The press component (12) swings up and down because of the swing of the rod (11) and press and clamp the bar (7) through the driving the hydraulic pressure cylinder (16) when cutting.

The invention discloses a contact structure and method for eliminating closing bounce, and pertains to the technical field of power electronics. The contact structure comprises an upper moving contact, a fixed contact, a lower moving contact, a first electromagnetic coil (501), a second electromagnetic coil (502), a first spring (601), a second spring (602), and a device shell (800). Grid line connection and disconnection are realized through the contact structure. Two ends of a grid line are connected onto the upper moving contact and the fixed contact separately. When the line is disconnected, the upper moving contact is separated from the fixed contact, and the lower moving contact and the fixed contact are closed. The upper moving contact is moved downwards under the action of the electromagnetic coil (501), and when the upper moving contact and the fixed contact are in collision, the impulse is transferred downwards, and the upper moving contact bounce can be eliminated through impulse transfer. The impulse is obtained by the lower moving contact so as to be bounced out and separated from the fixed contact. The impact energy is consumed by the second spring (602) finally. The upper moving contact is maintained to be in reliable contact with the fixed contact under the action of the first spring (601) to realize grid line connection.

The invention discloses a push-rod high-power electromagnetic relay which comprises an electromagnetic system, an insulating hood, a base, a normally closed static contact group, a movable contact group and a normally open static contact group, wherein the normally closed static contact group, the movable contact group and the normally open static contact group are fixedly arranged on the base in a near-far sequence from the electromagnetic system. The electromagnetic relay is characterized in that a first bending part and at least one normally closed static leading pin connected with the first bending part are arranged at the lower end of a normally closed static contact piece; a first clamping groove used for correspondingly clamping the first bending part and a first inserting groove used for correspondingly inserting the normally closed static leading pins are formed in the base; the first bending part is completely clamped into the first clamping groove; the insulating hood is arranged above the first bending part of the static contact piece, and fixedly connected with the base; and first strip groove holes are symmetrically formed on the left side and the right side of the upper part of a movable spring. The electromagnetic relay has the advantages that the load transfer capacity of contact points can be improved to the greatest extent under the condition that a boundary dimension of the electromagnetic relay and mounting dimensions of the leading pins are defined; and a good insulating property and reliable contact of the contact points can be ensured.

The present invention provides a cutting device that eliminates bouncing of a bar during cutting and facilitates replacement of a fixed knife or a pressing member and cleaning around the fixed knife or the pressing member. The pressing member-side inclined surface of the pressing member is pressed down by the clamping block-side inclined surface of the clamping block, and the bar is pressed and clamped by the pressing portion of the pressing bush. The inclination angle of the clamp block-side inclined surface and the pressing member-side inclined surface is formed at 6 degrees. The inclination angle is formed at such an angle that the component force of the pressing is smaller than the maximum frictional force between the inclined surface on the pressing member side and the inclined surface on the clamping block side. Even if the member is pressed, the clamping block and the piston rod will not return to the left (non-clamping direction). The bouncing of the bar during cutting is eliminated, the cutting accuracy is improved, and a stable billet can be produced.
