The present invention provides a protective coating for protecting a substrate from deleterious elements present in environments in which the substrates are deployed and methods and apparatus for deploying a PVC encasement with a longitudinal snap jacket of suitable length and girth to coat a pylon substrate or building girder and provide a filler within the snap jacket and around an encased pylon.

A modular plastic pipe formation apparatus, wherein at least two components of the pipe formation apparatus are disposed with respect to at least one or more respective modules.

A vehicle running board includes opposing vertical walls extending along a length of a tubular structure and including a carbon-fiber component. Opposing horizontal walls extend between the opposing vertical walls and include a glass component. The opposing vertical and opposing horizontal walls form the tubular structure having a generally rectilinear cross section. A polymer outer covering extends over the opposing vertical and opposing horizontal walls.

A spray quenching system including a quench box configured to receive a part for quenching. The system may include mechanical arms disposed within the quench box and thermocouples disposed on the mechanical arms that may be moved to contact the part surface. The system may include non-contact temperature sensors within the quench box that measure the temperature part surface, and spray nozzles within the quench box that spray the part with a quenching fluid. The system may include a controller in electronic communication with the mechanical arms, the spray nozzles, the thermocouples, and the non-contact temperature sensors, that is configured to initiate a quenching process, receive temperature data, analyze the temperature data to determine a temperature difference value, determine that the temperature difference value exceeds a threshold temperature difference value, and adjust the quenching process if the temperature difference value exceeds the threshold temperature difference value.

A process for forming a biofilm carrier suitable for use in a moving bed biofilm reactor (MBBR) is presented. A blowing agent is mixed with a plastic material to form a blended material. The blended material is then heated to a temperature where the blowing agent liberates gas by decomposition. The heated blended material is extruded through a die to provide the extrudate with a profile of the biofilm carrier. Advantageously, biofilm carriers produced in this manner have increased effectiveness when compared to conventional biofilm carriers.

A method for the production control of an extruded plastic product with the following steps: recording at a first measuring point a first actual temperature of a measuring area provided on the plastic product, recording a second actual temperature of the measuring area at a second measuring point which is arranged at a distance from the first measuring point in a direction of extrusion of the plastic product, determining a setpoint temperature of the measuring area at the second measuring point, and outputting information on whether the second actual temperature is inside or outside a prescribed tolerance range of the setpoint temperature.

An extrusion press device (1) and a method are for an extrusion material (3) which has small loose plant parts, in particular wood chips, provided with binder. The extrusion press device (1) has an extrusion press (7) which presses the supplied loose extrusion material (3) and shapes same into a strand (8) and which advances the strand in an extrusion direction (9). The extrusion press (7) has a shaping device (21) which forms one or more inner tubular cavities in the strand (8) in the extrusion direction (9). The extrusion press (7) forms a continuous strand (8) with one or more inner tubular cavities (29) during the extrusion process, the cavities being closed by the extrusion material (3) at the end face.

Described is a peelable heat shrink tube composed of a fluororesin and having a determination coefficient calculated from [Equation 1] below using an elastic modulus ratio (%) of more than 0, but 0.90 or less:

[00001]$\begin{array}{cc}\mathrm{Determination}\mathrm{coefficient}={\left(\mathrm{correlation}\mathrm{coefficient}\right)}^2={\left[\frac{\left(\mathrm{covariance}\right)}{\left(\mathrm{standard}\mathrm{deviation}\mathrm{of}X\right)\left(\mathrm{standard}\mathrm{deviation}\mathrm{of}Y\right)}\right]}^2& \left[\mathrm{Equation}1\right]\end{array}$

where X, Y and covariance represent the following: X: Proportion of the position of each point, where the elastic modulus was measured, from the interior of the tube Y: Elastic modulus ratio in each region Covariance: Average of the product of deviations of X and Y.

There is disclosed a production device for a loose tube-type optical cable in which an optical fiber bundle is housed in a tube. The production device includes: a resin extruder configured to extrude and coat a resin onto the optical fiber bundle; and a water tank configured to store cooling water for cooling the resin to form the tube, wherein: the resin extruder includes: an extruder die having an extrusion port for the resin; a pipe penetrating the extruder die; and an air pump mechanism configured to pump air to the pipe; and the water tank includes: a sizing die having an inlet, a passage port, and a suction port for the cooling water; and a cooling water suction mechanism configured to suck the cooling water from the sizing die.

An apparatus for starting an extrusion process, including at least a drawing device having a main frame, a platform arranged on the main frame, a cable winch arranged on the platform and having a drum, and a wire cable that can be wound up on the drum of the cable winch and pulls an extruded plastics pipe in an extrusion line by way of deflection rolls until the pipe is taken over by a take-off device, wherein the platform is movable transversely to an extrusion direction.
