Abstract: The present disclosure discloses an industrial vehicle driving in four directions and a traveling mechanism for the industrial vehicle. The traveling mechanism for the industrial vehicle driving in four directions comprises four wheel sets at bottom of the vehicle body, the wheel sets are sequentially connected to form a quadrangle; one wheel set is a rotating wheel set, another wheel set is a reversible directional wheel set, and the axis direction of the rotating wheels is switched between two directions through the rotating action of a rotating shaft of the wheel set; the other two wheel sets are variable-state wheel sets, and the rotating wheel state are switched between a directional state and a follow-up universal state. The present disclosure has simple structure, low cost, good supporting stability, and usage range, usage efficiency and maneuvering capability of the industrial vehicle are facilitated.

Abstract: A flexible conduit fitting system includes a housing that defines at least part of a flexible conduit fitting, and a resilient clip supported by the housing. The flexible conduit fitting may include an aperture for receiving an end of a flexible wiring conduit. The resilient clip may have an engagement portion that extends into the aperture of the flexible conduit fitting to engage the generally corrugated outer structure of the flexible wiring conduit. The housing may be configured to support the resilient clip in a manner that allows the resilient clip to flex in a direction of movement of the flexible wiring conduit when the flexible wiring conduit is being inserted into the aperture and past the engagement portion, but to not substantially flex in the direction of movement of the flexible wiring conduit when attempting to withdraw the flexible wiring conduit from the aperture.

Abstract: A macromolecule-based conductive composite material and a PTC element. The macromolecule-based conductive composite material comprises: a macromolecule base material, having a volume fraction of the macromolecule base material of 20%-75%; a conductive filler with a core-shell granule structure and dispersed in the macromolecule base material, having a volume fraction of 25%-80%; and a coupling agent, being a titanate coupling agent and accounting for 0%-5% of the volume of the conductive filler. The PTC element prepared by using the macromolecule-based conductive composite material comprises at least two metal electrode plates (12, 12?), a macromolecule-based conductive composite material (11) being closely combined with the metal electrode plates (12, 12?). The PTC element prepared from the macromolecule-based conductive composite material has the advantages of low room-temperature resistivity, outstanding weather durability, good voltage resistance and good resistor repeatability.

Abstract: A rotary die head for a film blowing machine for use with a starch-based biodegradable material including a core mould and an outer body. The core mould includes a spiral core mould sleeved on a center pivot and a rotary core mould fixed on the center pivot, jointed with each other. A motor drives the center pivot and the rotary core mould to rotate. The outer body includes an inner die casing sleeved on the spiral core mould, an outer die casing fit with the inner die casing, and a mouth die casing. The inner die casing, the mouth die casing, the spiral core mould, and the rotary core mould form a material flow and molding channel consisting of a herringbone feed-in slot, spiral conveying slots, an annular gap buffer zone, a tapering cone passage, an annular loosing cavity, and a final molding gap in turn from bottom to top.

Abstract: The invention relates to a method of making culture medium for Agaricus blazei Murill mushroom, which include the following steps: the sawdust is piled up to 5 to 15 meters high to undergo the first fermentation and decaying process which takes about 3 months; it is required to periodically turn over the sad dust pile every 15 to 30 days; then the dried and sterilized cattle excrements are added to the first-time fermented sawdust to undergo the second fermentation process, wherein the saw dust is piled up to 5 to 15 meters high and the internal fermentation temperature is 70 to 90 degrees centigrade; it is required to periodically turn over the sad dust pile every 15 to 30 days; finally, when the color of fermented sawdust turns dark brown, close to black, and the urine like Ammonia odor disappears, the culture medium can be used as the basic materials of bag-logs for cultivating Agaricus blazei Murill mushroom.

Abstract: The invention relates to cultivation method of Agaricus blazei Murill mushroom which includes the following steps: preparing the mushroom spawn; inoculating spawn onto the bag-logs and carrying out the bag-log warming process; transplanting bag-logs to soil; covering casing soil onto the mushroom bed; slightly watering the mushroom bed to maintain the moisture content after the hypha germinates; conducting the induction to primordium process when the bag-logs are filled with hypha; keeping the mushroom bed ventilated and moist when the carpophores (fruiting bodies) grow up to 2 to 3 millimeters; and finally harvesting.

Abstract: An optical waveguide and method for guiding a laser beam through a channel member having a fluid medium disposed therein. A refractive index gradient is created in the fluid medium which causes the fluid medium to guide the laser beam through the channel member. The refractive index gradient results when a temperature index gradient is created in the fluid medium by heating the channel member wall. The channel member can be externally heated using a separate heating source or the channel member can be heated from the inside by the laser beam itself. A fluid pump is used to create a fluid flow in the fluid medium in order to maintain the temperature and refractive index gradients in the fluid medium.

Abstract: A laser transponder and method for disabling a laser-based speed monitor of the type that transmits a monitor laser beam at a moving motor vehicle. The monitor laser beam transmitted by the speed monitor is detected when it arrives at the motor vehicle. In response to detecting the monitor laser beam, a warning is output to the motor vehicle driver and a jamming laser beam is transmitted toward the speed monitor. The jamming laser beam includes a plurality of pulses separated from each other by a time period that is less than or equal to an amount of time needed for the monitor laser beam to travel from the speed monitor to the motor vehicle and back to the speed monitor. The jamming laser beam disables the speed monitor for a time period sufficient to allow the motor vehicle driver to reduce the speed of the motor vehicle.

Abstract: A laser scanner having first and second scanning mirrors and a correction circuit that removes distortions caused by interaction between the scanning mirrors. Preferably, the first scanner mirror is an off-axis mirror that is positioned to produce a single, substantially invariant pupil on the second scanning mirror. Preferably the scanner uses a reflective beam expander to magnify an input laser beam received from a laser source. Preferably, the reflective beam expander is implemented using two spherical mirrors positioned to form the input laser beam into a Z-folded beam path. The folded beam path increases the distance between the laser source and the focusing lens, which results in a clear focused spot and does so using spherical mirrors which are much less expensive than the infrared lenses used in the prior art. The reflective beam expander is also wavelength insensitive.
