摘要:
The object of the present invention is to provide a high volume, low cost, sealant spray control system for the asphalt industry, accomplished particularly through a self contained vehicle mounted spray system utilizing a digital positioning receiver consisting of a global positioning system (GPS) or horn radar for vehicle speed sensing and a motor RPM sensor and a program logic CAN micro controller for adjusting output flow of a material pump to achieve a target application spray rate of a spray bar.

This invention is directed to a device for applying slurry manure beneath the soil or on top of the soil with reduced crop displacement by a trailing feeder hose. More specifically, the invention is directed to an improvement of the prior art slurry reel system. The slurry reel system of the present invention places the axis of the reel spool parallel with the direction of travel instead of the conventional perpendicular orientation. This invention also utilizes a unique hose placement and retrieval apparatus or boom.

An agricultural sprayer implement which includes a wheeled main body and a cantilevered boom. The cantilevered boom has a plurality of sections which fold with respect to one another and place significant torsional stress on one or more of the boom sections. The interior boom sections have a cylindrical tube as a lower member and preferably a square tube as an upper member with a plurality of braces extending between them. The cylindrical tube resists the torsional stress which is maximized during folding of the boom. The square tube resists particularly an upward/downward bending moment.

A road finisher F for producing a continuous sprayed carpet T of a bonding agent on a planum has a spraying system S on a vehicle having at least two spraying facilities 11, 11′, 14, 14′ which are located offset to each other in the and laterally to the traveling motion direction R and a control device which operates the spraying facilities using a method such that during a traveling motion of the vehicle a sprayed carpet T is produced with front and rear boundaries V, H which are continuous over the width of the sprayed carpet and which are parallel to a respective reference line L which is placed on the planum in front of the spraying facility which is the frontmost in traveling motion direction. The sprayed carpet T is produced such that each spraying facility 11, 11′, 14, 14′ first is activated or deactivated depending on the traveling motion with a predetermined distance from the or when reaching the respective reference line L.

The present invention discloses and claims a single vehicle that has both full fire fighting capability in the form of a pumper in permanent combination with full medical rescue and transport capability. Provided is a transport pumper of conventional design having a crew cab with four entrances, a large capacity fire pump, a tank containing a quantity of water, another tank containing a quantity of foam, a substantial length and diameter of fire hose, ground ladders, a side controlled pump operator's panel, and all other necessary equipment to be in substantial compliance with NFPA Standard 1901. Permanently provided on the same chassis as the pumper is an ambulance or rescue transport including rear entry double doors for patients, a rear dump capability, two supine patients on stretchers carrying capabilities, air conditioning, a side entrance door and all necessary equipment be in substantial compliance with federal standard KKK-A-1822E for a rescue transport. The rescue transport is modified only to the extent necessary to accommodate ground ladders and a hose bed on the top of the rescue transport. The vehicle concept is one of a modular design in permanent combination on a single chassis using standardized equipment already familiar to fire rescue personnel which can be readily refurbished and replaced with conventional equipment at minimized cost.
摘要:
A method for bonding together an existing substrate layer and a pavement layer, such that a strong adhesive bond is formed by using a tack coat, provided by an asphalt emulsion, in between the layers as the bond coat. The tack coat layer is a low-tracking coating which cures quickly such that the pavement layer may be applied to the substrate, hours to days after the emulsion is applied to the substrate. The asphalt emulsion comprises at least a first phase of from about 30% to about 70% of an asphalt composition, about 30% to about 70% water, and about 0.1% to about 3.0% emulsifying agent, stabilizer and/or additives, or 0.1% to about 30% if polymeric or other additives are also included.

A sunless tanning system is provided that includes a base unit and a handheld sprayer assembly fluidly coupled to each other via at least one hose. The base unit includes at least one fluid reservoir configured to contain a sunless tanning solution. The handheld sprayer assembly includes an activation device configured to activate the sunless tanning system and a nozzle in fluid communication with the at least one fluid reservoir. The nozzle is configured to eject tanning solution onto an application surface upon activation of the activation device.
摘要:
An assembly for distributing particulate material comprising a blower assembly which is preferably removably mounted on a mobile platform and structured to generate a forced flow of air along a flow path and through a manifold assembly connected to a supply of material being distributed. The manifold assembly includes a receiving segment incorporating a Venturi section facilitating the entrainment of the material into the forced air flow passing through a discharge conduit preferably having an extended length to facilitate distribution of the material to a plurality of locations in a variety of different environments. A vent assembly is provided to relieve back pressure from within the discharge conduit, which may be created due to its extended length.
摘要:
A spreader box for spreading cold mixed asphaltic concrete paving mixtures including a supporting frame or "bridge" attached to a left and right side plate. Within the spreader box and at the front portion of the box is situated a left and right side hydraulic motor or other power means, which is used to power a left and right side auger for lateral distribution of the paving mixture. Adjustment means on each end and in the middle to allow for vertical adjustment of the distribution auger. A left and right side "ROLLING SCREED" roll which has an adjustment means on each end and in the middle to allow for vertical adjustment of depth of spread.A left and right side compression roll which has adjustment means at each end and in the center for vertical adjustment of down pressure. Screed roll and compression roll connected by chain and sprocket or other power transfer means. One or more wheels or caterpillar tracks are mounted on each side plate.
摘要:
An asphalt paver, of the type having a power extendable floating screed, is provided with a power extendable auger-like material distribution mechanism, such that the width of the distribution mechanism can be varied with the width of the screed. The variable width distribution mechanism is structurally independent of the floating screed, so as not to impart its reaction forces to the screed.A variable width panel arrangement is incorporated into the power extendable distribution mechanism and is extendable and retractable along with the latter to provide for proper confinement of the paving material during lateral distribution.
