Abstract:
A transversely stiff conveyor belt in which a layer of elastomeric material is disposed between a carrying surface and a nuclear layer and in which another layer of elastomeric material is disposed between the nuclear layer and a treading surface. One layer of elastomeric material has a filament network embedded therein which comprises slightly-extendable transversely-disposed weft filaments and substantially-extendable longitudinally-disposed warp filaments. The other layer of elastomeric material has at least one filament network embedded therein which comprises high-strength longitudinally-disposed warp filaments and bending-resistant transversely-disposed weft filaments.
Abstract:
A method for dividing a block of deep-frozen foodstuffs, especially fish fillets, into portions of predetermined size. The method utilizes a operating temperature between -6.degree. C. and -30.degree. C. and a processing pressure of at least 100 at. In the method, the block is squeezed in a first direction, preferably perpendicular to its largest or greatest surface, through a blade lattice formed of parallel knives. The plates formed by squeezing the block through the first blade lattice are carved into portions of desired size by performing second cuts perpendicular to the first cuts. The second cuts are preferably perpendicular to the largest surface of the original block. In a preferred embodiment, the second cuts are performed by squeezing the plates through a second blade lattice formed of parallel knives. As the block or plates are being squeezed through the blade lattice, they can be squeezed in another direction perpendicular to the direction of squeezing to increase their height. An apparatus for performing the described method is also disclosed.
Abstract:
A method and apparatus for forming slabs and shaped bars of food material such as fish or meat. The material is extruded at a very high pressure while deep frozen and via an extrusion nozzle which is shaped to build up back pressure to improve uniformity of extrusion.
Abstract:
An endless flexible conveyor belt has a load-supporting portion and two upstanding side walls thereon. The sidewalls are corrugated, each being formed with a plurality of transverse major folds at least some of which have one or more minor or auxiliary folds incorporated in them.
Abstract:
A foldable ramp for use with vehicles wherein the ramp has a base with an arch plate for eliminating the step up to the ramp surface and an arched bridge to eliminate the step from the top of the ramp to the bed of a vehicle. A foot at the end of the arched bridge is pivotable and allows the ramp to engage the vehicle bed with a flat portion for stably engaging the truck. An adjustable belt connected between the vehicle and the ramp secures the ramp to the vehicle and prevents slipping. The ramp is foldable along its length for ease of storage. The ramp may have one bi-fold ramp for a short wheelbase use or narrow need uses, a tri-fold ramp for wider wheelbase use or two separated bi-fold ramp sections for wide wheelbase uses.
Abstract:
The sample gas is divided into two portions, one being subjected to flame ionization detection to measure all hydrocarbons, the other one being passed through a tube having active carbon to remove all higher hydrocarbons by adsorption except methane. The resulting gas is also subjected to flame ionization detection and the difference in detection gives the non-methane impurities, either electrically as difference signal or graphically. The adsorber tube may be exchanged for another one while the former is cleaned and purged. A simple flame ionization detector is used alternatingly or two are operated in parallel to obtain the two readings.
Abstract:
The present invention provides a composite vehicle trim panel having enhanced sound transmission characteristics and a method for manufacturing the same. In the most preferred embodiment, the composite vehicle trim panel comprises a substrate layer with a first aperture, a second substrate layer with a second aperture, and a grid interposed between the first substrate layer and the second substrate layer. The grid overlays the first aperture and the second aperture, which are aligned with each other. The first substrate layer, grid, and second substrate layer are secured to each other by compression molding to form a composite vehicle trim panel. A finish layer is then laminated to the first substrate layer. The use of the grid provides an increased open area for sound transmission through the composite vehicle trim panel over previous designs.
