Abstract:
@ The apparatus for applying to a road, (1), run-way or equivalent a point-formed or dotted paint or marking (M") especially a traffic indication line comprises a reservoir (R) containing a supply of highly viscous material (M) to be applied to the road (1) and a nozzle section (10, 10') in itself comprising - conduits (11) ending in orifice zones (11', 11") for forming preliminary stages (M') of highly viscous drops and - means (20, 20', 20") for flinging the drops down into engagement with the road (1). In a mechanical embodiment the orifice zones (11') of the conduits (11) are placed on a cylinder surface (12) and are mutually separated by means of partition walls (13) and the means (20) for flinging the material down into engagement with the road comprise a rotatory shaft (21) and a number of shovel blades (22). In a pneumatic embodiment the means (30) for flinging the drops down into engagement with the road (1) comprise a plurality of compressed air tubes (20') each leading to an orifice zone (11") and another plurality of tubes (20") leading away from the said zone (11"). These apparatus constitute simple and cheap embodiments of an apparatus which effectively flings the marking mass into contact with the road.
Abstract:
A coating apparatus including a lip body for the leaving therefrom of the coating composition forms a very stable and uniform curtain if such lip body determines a negative (front) slide surface associated with a back negative surface.
Abstract:
A coating device has a first half (14) and a second half (16) located adjacent the first half to form a slot (18) between the first and second halves. A porous material (10), having a tickness greater than the height of the slot (18), is disposed in the slot to compress uniformly along its width. The porous material (10) has a porosity and a height selected in combination with each other to create a predetermined pressure drop through the slot (18) and to maintain the pressure drop to create the desired flow rate along the slot width. The size of the pores in the porous material (10) can be less than 25 mu m and the exit pressure drop through the slot can be at least one thousand times greater than could be obtained without the porous material.
Abstract:
A method and apparatus for application of heat curable liquid (15) onto substrates is provided. The present invention allows high speed selective application of curable liquid (15) to a continuous succession of discrete substrates (74) disposed on a conveyor belt (18). Each substrate (74) is stabilized on the conveyor belt (18) via a stationary magnetic device (42), liquid applicator guns (30) are adjusted along a desired axis in relation to each substrate (74), heat curable liquid is applied, and each coated substrate is cured via heating device (54) in order to form a solid or foamed coating on at least a portion of each substrate. The present invention provides increased speed efficiency and adherence of the liquid cured onto the substrates.
Abstract:
A painting system made up of a porous substrate sheet (12) mounted on an impermeable support (14), the sheet having preformed therein a picture (35) in outline, the outline being waterproof barrier bands (30) which thereby form discrete segments within the porous sheet (12), there being disposed in the sheet (12) a multiplicity of concentrated dye spots (36) whereby addition of water to the porous sheet (12) causes dissolution of the individual dye spots (36) and migration of dissolved dye within each segment of the porous sheet (12) to the limits set by the aforementioned barrier bands (30), ultimately forming the picture (35) that had been outlined in the porous sheet (12) by the barrier bands (30).
Abstract:
A sealing gun (31) of a sealing application device for controlling a flowrate of a sealing material in accordance with a magnitude of an input signal is secured to the forward end of an arm of a robot. The strength of a signal being input to the sealing application device (30) is increasingly or decreasingly controlled in conformity with the increasing or decreasing control of a moving speed of the sealing gun. The moving speed (TSA) of the sealing gun is proportional to the flowrate of the sealing material from the sealing gun, so that a width of bead becomes uniform regardless of the moving speed (TSA) of the sealing gun.
Abstract:
A device for delivering accurately a viscous liquid such as an electrically conductive adhesive or creamy solder in a predetermined quantity at a time. In order to detect correctly a quantity of the liquid remaining in a syringe and any change in the internal pressure of the syringe, to assure the constant delivery accordingly and to prevent dripping of the liquid, a first pressure sensor is disposed in a pipeline between a solenoid change-over valve for delivery and the syringe, and a second pressure sensor and an accumulator are disposed in a pipeline between the solenoid change-over valve for delivery and an air supply source, so as to control the output time of a shift signal on the basis of a change in the integration value of a measurement pressure at the first pressure sensor within a predetermined shift signal output time.
Abstract:
Apparatus is provided for applying lubricating material to each surface of a continuous strip (138) of aluminum wherein a first applicator roll (46) transfers lubricating material from first supply tank (90) to the outer surface of a first coating roll (56) and a second applicator roll (72) transfers lubricating material from a second supply tank (102) to the outer surface of a second coating roll (80) and the continuous strip (138) of aluminum is passed between the first and second coating rolls to have the lubricating material applied to each surface thereof. The second coating roll (80) is rotated by a suitable drive means (140) and is positively connected to the second applicator roll (72), the first coating roll (56) and the first applicator roll (46) so as to rotate these rolls. The apparatus permits differing amounts or kinds of lubricating material to be applied to the surfaces of the continuous strip of aluminum.
Abstract:
Disclosed is an apparatus for depositing a viscous flowable mass to coat or decorate the surface of a product (26). The apparatus has a linearly moveable manifold assembly (28) with at least one nozzle (42) for depositing the viscous material on the surface of a product (26) passing beneath the nozzle (42), a counterbalance eccentric drive system (44), and a linear motion assembly (46) connected to the drive system (44) and manifold assembly (28). At least one of the assembly (28) and nozzle (42) is heat traced and controlled so as to maintain the temperature of the viscous material in a range such that the material is flowable. By changing at least one of (a) the speed of the moving manifold assembly (28), (b) the speed of the product (26) under the nozzle (42), and (c) the stroke length, the product surface can be ornamented in a variety of ways. The apparatus is particularly useful for decorating a food product (26) with icing.
