Abstract: A pattern mechanism for a knitting machine which is adapted to selectively control longitudinal movement of needles in their slots. The needles are provided with jacks in operating relationship thereto for moving the needle in a longitudinal direction. A separate butt element is carried by the jack and is movable relative to the jack both longitudinally and transversely in at least two alternate modes. One of the modes provides lesser longitudinal free movement of the butt element relative to the jack body than the other of the modes. All of the butt elements carried by a series of jack bodies are cammed to the mode which permits greater longitudinal free movement. Selected ones of the butts are moved to the mode providing lesser longitudinal free movement so that only the jack bodies carrying the selected butt elements will be elevated by a raised cam.

The blend back proportioning valve includes a proportioning piston which cooperates with a valve seat to maintain increases in rear brake pressure proportional to but less than increases in master cylinder pressure between a first predetermined pressure and a second predetermined pressure. A blend back spool moves the valve seat away from the proportioning piston to equalize master cylinder pressure and rear brake pressure when the second predetermined pressure is reached.

Abstract: A tubular infrared lamp is mounted within the confines of a reflector and includes flattened, jacketed terminal structure on each end of the tube. Each terminal end extends through appropriately sized apertures in the opposed end walls of the reflector with the apertures including notches for receipt of the flattened terminals. Insulated terminal posts are mounted on the exterior side of the reflector end walls and wire leads extend tightly between the lamp ends and the corresponding post to secure the lamp against excessive axial movement. An insulating shield having an aperture, including notches, of similar size and configuration as the aperture of the end walls is disposed against the external surface of the end wall. The shield is oriented so that the notches of each respective aperture are in non-alignment, thus blocking cooling air flow, passing over the lamp ends, from entering the reflector.

The wetted glove body is then tumble dried at an elevated temperature to simultaneously further cure the latex and dry the water from the slurry. The dried slurry forms a substantially uniform coating substantially fully covering both the interior and exterior of the glove body.

Abstract: A multiple bimetallic snap disc thermostat is disclosed in which two series connected switch mechanisms are respectively operated by two concentric bimetal snap discs having the same diameter. One snap disc is thermally automatic in operation to open and close its associated switch upon reaching its calibration temperatures. The outer disc is a one-shot disc which does not automatically reset and cannot be manually reset after operation. The two discs are mounted in a single, disc retaining cup, and are spaced by a ring positioned between their peripheries. This allows said discs to be formed of the same size and provides easy mounting. A single fixed contact member provides the fixed contact for both switches. The contacts of the switch associated with the automatic disc are capable of repeated operation whereas the contacts of the switch associated with the one-shot disc are not structured for repeated cycling.

Abstract: An adjustable bimetal snap disc thermostat is disclosed in which a leaf spring acts at its center to apply a force to a bimetal snap disc to alter the operating temperature thereof.
