An infinitely variable transmission requiring no external controls is shown in its preferred embodiment of the present invention as including a power housing rotatably mounted on an input and an output shaft. The output shaft includes a planetary cage and planetary gears located in the interior of the power housing. The planetary gears are in gearing relation with a sun gear located on the input shaft in the interior of the power housing and also in gearing relation with a ring gear formed as part of the power housing. Lubricant is provided in the interior of the power housing. If the load is sufficient to cause slippage, the resistance of the load coupled to the input rotation causes the power housing to rotate in a direction opposite to the direction of the input and output shafts when the output is initially accelerated. The internal resistance of the transmission created by the drag and friction of the drive, planetary, and ring gears gearing together and the viscosity of the lubricant influences the rotation and acceleration of the output. As the output load is accelerated and the input r.p.m. increases to a more constant level, overcoming initial load, the output load will decrease proportionately causing the power housing to decelerate. When the output load decreases to a point where there is less resistance to further accelerate the load than the internal resistance in the transmission, the output housing will cease rotation and begin rotating in the same direction as the direction of the input and output as the output is further accelerated.

This invention relates to resin blends of naphthol resins and novolak resins. Naphthol resins are acid catalyzed condensation products of an aromatic alcohol with an aldehyde where the aromatic alcohol is a naphthol or a mixture of a naphthol and a phenol. The blends of the invention preferably contain a total of from 5 to 35 mole percent repeating units derived from naphthol. The blends are useful as molding compounds or as film forming materials.

A food molding mechanism for a patty-forming machine that uses a servomotor to drive a crank arrangement. The crank arrangement drives a mold plate. The mechanism uses a reducer with a replaceable output shaft. The reducer engages a servomotor utilizing a double enveloping worm gear providing gear enmeshment across an arc portion of the servomotor main gear. A servomotor driven knockout apparatus comprises a cam and lever arrangement. Oil reservoirs for the knock-out cams are substantially sealed in the mold cover.

The disclosure includes a method of screening for, diagnosing or detecting non-small cell lung carcinoma or an increased likelihood of developing non-small cell lung carcinoma in a subject. The method comprises: (a) determining the level of at least one biomarker in a test sample from the subject wherein the at least one biomarker is selected from the biomarkers set out in Table 2, 4A, 4B, 6 and/or 7; and (b) comparing the level of the at least one biomarker in the test sample with a control; wherein detecting a difference in the level of the at least one biomarker in the test sample compared to the control is indicative of whether the subject has or does not have non-small cell lung carcinoma or an increased likelihood of developing non-small cell lung carcinoma.

The food product machine with a food supply, a rotary food pump connected to the food supply, a molding mechanism having a mold plate and a knockout drive, and a the mold plate configured to be driven to reciprocated between a fill and a discharge position. The knockout drive is reciprocating a knockout plunger to discharge molded food products from a cavity in the mold plate, the mold plate being reciprocated by a mold plate drive between a cavity fill position and a cavity discharge position. The machine further includes a manifold connected an outlet of the food pump and having an outlet passageway connected to an inlet of the molding mechanism for filling the cavity of the mold plate.

A power supply includes an isolation transformer. The isolation transformer includes a primary winding and N secondary windings, where N is an integer. The primary winding receives a first alternating current voltage. Each of the N secondary windings generates a second alternating current voltage. M rectifiers convert the second alternating current voltages to a direct current voltage, where M is an integer. X inverters convert the direct current voltage to a third alternating current voltage, where X is an integer. A reference transformer is electrically coupled between the X inverters and output terminals of the power supply, is connected in parallel with the output terminals, and is configured to provide at least one of a neutral reference and a ground reference.
摘要:
A knockout mechanism for a food patty forming machine with one or more knockout cups for ejecting formed food from a cavity of a reciprocating mold plate. A rocker arm moves the knockout cup between a raised position and a knockout position. A linear actuator applies force to the knockout cup to move the knockout cup from the raised position to the knockout position. A spring also applies force on the rocker arm to move the knockout cup.

An elongate tubular body extends between a rotatable cutter and a control. The cutter is connected to the control with a rotatable element. A vacuum is applied through an annular passage defined between the tubular body and the rotatable element. The cutter has at least one radial projection which cooperates with at least one stationary element on the tubular body to cut material drawn into the tubular body. Material that has been processed by the cutter is aspirated through the tubular body for disposal.
