Abstract: In combination, a mechanical actuator and a speed changer coupled directly to one another. The mechanical actuator comprises an actuator housing, an actuator output shaft supported within the actuator housing for linear reciprocation inwardly and outwardly therefrom, an actuator input shaft supported rotationally within the actuator housing with an end of the actuator input shaft projecting outwardly from the actuator housing, and a mechanical arrangement within the actuator housing for translating rotational motion of the actuator input shaft into linear motion of the actuator output shaft. The speed changer comprises a changer housing having an output flange abutted with and affixed directly to the actuator housing in surrounding relation to the actuator input shaft and a changer output shaft supported rotationally within the output flange. The changer output shaft is formed with a blind hole for receiving the actuator input shaft.

Abstract: A process for extruding of products from fluoropolymers preferably shaped as rods or tubes which have unique physical and other properties resulting from the addition of nanoparticles under unique processing conditions while also utilizing accurate control of processing parameters such as time and temperature and others according to novel methods.

Abstract: An apparatus and method for mixing fuel and oil, to achieve a desired mixture ratio, includes calculating a required number of fuel units, to be mixed with a predetermined volume of oil, for achieving the desired mixture ratio, as a function of calculation terms including the desired mixture ratio and an arbitrarily selected correlation number correlating the predetermined volume of oil to the desired mixture ratio. The required number of fuel units is thus calculated without the use of a calculation term equaling the predetermined volume of oil, thereby facilitating accurate mixing of even custom mixture ratios with simple calculations that can be done mentally.

Abstract: A process is described for recovering sodium carbonate or other sodium-based chemicals from sodium-bearing streams, including in particular mine water, evaporative pond water and sodium carbonate decahydrate deposits, recycle and purge streams, and other waste streams. In the process selected sodium bicarbonate-bearing streams are decarbonized to reduce the sodium bicarbonate concentration in a combination with other sodium-bearing streams, resulting in a liquor suitable as feed to a sodium carbonate decahydrate or sodium carbonate monohydrate process. The sodium bicarbonate concentration can be reduced using any number of known processes such as reacting said sodium bicarbonate with a neutralizing agent such as calcium oxide, calcium hydroxide, sodium hydroxide, or other alkali. Sodium bicarbonate can also be stripped using steam or air.

Abstract: A method of utilizing an adjustable height bladder securement mechanism to effect advantageous bladder movement during a loading and shaping process is disclosed. A tire press comprises a lower mold, an upper mold, and a center mechanism. The center mechanism has an upper clamping mechanism for securing the upper periphery of a bladder and a lower clamping mechanism for securing the lower periphery of the bladder. A center mechanism tube has a center rod positioned therein. A piston is disposed within the center mechanism tube. The piston provides reciprocating motion to the center rod. A position sensor mechanism is operatively associated with the center mechanism.

Abstract: A device for handling containers, such as drums, is provided to facilitate holding a drum during drum handling by engaging the drum with a first clamping member and a second clamping member which can be selectively locked with a locking mechanism to facilitate the secure holding of the drum during handling by facilitating the maintenance of the drum in clamped engagement with the device.

Abstract: A corrosion inhibited chloride salt is provided containing 30-38% by weight calcium chloride and up to 50% by weight based on the weight of the salt, of honey. This composition reduces the corrosivity of chloride salt up to as much as about 70% compared to that of the untreated sodium chloride solution. The corrosion-inhibited salt finds uses in a variety of applications, such as, for roadway deicing, freezeproofing, concrete additive and for dust suppression for example.

Abstract: A convertible hand cart convertible between a two wheel hand cart for vertically loading of materials and a four wheel hand cart providing a horizontal material loading platform. The wheel structure for providing the four wheel configuration is pivotably secured to the two wheel structure and movable between the two wheel and four wheel configurations. The two wheel configuration includes structures for locking up the wheel structure for the four wheel configuration thereto. The locking structure is constructed and defined with minimum parts and operable based on vertical sliding action to minimize wear on the locking structure parts. A foot operative mechanism is provided to release the locking structure to permit the wheel structure to be released from a locked up position, hands free, to commence the reconfiguration to the four wheel cart.

Abstract: A method for relieving pressure in a vulcanized tire while still in a tire press is disclosed, wherein the bladder securement mechanism utilizes a position sensor mechanism and eliminates the need for spacers and a floating piston.
