Abstract: LF-2012-Ca HOT MELT METAL WORKING LUBRICANTS CONTAINING     PHOSPHORUS-CONTAINING COMPOSITIONS            ABSTRACT           Metal working operations, especially drawing, are facilitated by applying to the metal a composition which provides lubricity thereto, which melts between about 30° and about 150°C., and which contains a minor amount of a phosphorus-containing composition which may be prepared by the reaction of an alkoxylated alkyl phenol with a phos-phorus trihalide, or, in combination with water, with a triaryl phosphite.  The former reaction also produces, as a by-product, the corresponding halide.  The phosphorus-containing compositions are especially useful in combination with a chlorinated wax.  The preferred lubricant bases for the metal working lubricants comprise esters or polymers of epoxides or episulfides.

Abstract: AIR CUSHION SNUBBER APPARATUS            ABSTRACT OF THE DISCLOSURE     An improved snubber apparatus for an air cushion within a forming press is provided.  A floating piston is mounted within the air cushion and defines a snubbing chamber.  As the air cushion returns to its top stroke position after yieldably deforming to cushion a member within the forming press, a movable piston within the air cushion contacts the floating piston, forcing it to move in the direction reducing the volume of the snubbing chamber.  A check valve means is provided between a cushion chamber and the snubbing chamber which maintains the pressure in the snubbing chamber at a minimum equivalent to the pressure in the cushion chamber.  As the volume of the snubbing chamber is reduced, the air trapped within is rapidly compressed to a value snubbing the motion of the air cushion. The snubber valve is provided communicating with the snubbing chamber and maintained in a closed position by the air pressure within the cushion chamber.  During the snubbing action, when the air pressure within the snubbing chamber reaches a predetermined value, the snubber valve is opened permitting the air from the snubber chamber to escape through the valve to the surrounding atmosphere.  A orifice plug is provided to control the outflow of the air when the valve is open.  The relative cross-sectional areas exposed to the air pressure within the cushion chamber and the snubbing chamber on the snubber valve are varied to correspond to the number of cushion chambers in the air cushion.

Abstract: ABSTRACT OF THE DISCLOSURE A laser inspection system is provided having an absolute dc system in which the power gain of the system is stable and adjustable in order that the resultant signals which are generated from the system may be utilized to identify flaws as distinguished from flaws which may be identified simply by a change in signal relative to the background value.  In order to stabilize the power gain of the system and provide an absolute reference dc level or back-ground, a sample of the radiation from the laser beam which is utilized to scan the material being inspected is applied to the photomultiplier tube for generating a reference pedestal signal which is dependent on the intensity of the laser beam and is free of the influence of the characteristics of the material or product being inspected.  The reference pedestal signal is applied to a comparator which develops a control signal which is applied in a single feedback loop which includes in effect the laser source and the light collec-tion system or receiver within the loop.  This loop includes the photo-multiplier tube and its high voltage power supply to which the control signal is applied for stabilizing the gain of the system.  Accordingly, if the sensitivity of the receiver varies, or the photomultiplier drifts or if drift occurs in the power supply of the photomultiplier tube, or if the laser beam intensity drifts, the feedback loop will detect these changes and compensate for them, produce a stable and adjustable power gain for the system.  Accord-ingly, changes in response of the photomultiplier tube with respect to a pro-duct being examined will be due to product type changes, for example, products which differ in diffusivity, reflectivity, etc., and will not be due to changes in the system parameters such as sensitivity, temperature, etc.

Abstract: A B S T R A C T       A stator for electromagnetic stirring surrounds a continuous casting mold.  A conducting winding arrangement is provided for creating an electro-magnetic field in the mold and rotating about the axis thereof.  The conducting winding arrangement uses multiple phase electrical energization and has, for each phase, a group of conductors arranged to carry current down one side of the mold and up the opposite side.  The groups of conductors corresponding to the electrical phases arranged so that the overall result of such groups is to cause a magnetic field, with flux lines transverse to the mold axis to rotate about the mold axis at a rotational frequency dependent upon the characteristics of the electrical supply and the number of winding groups. A magnetically permeable path is provided surrounding such winding groups which path is substantially all located outside said windings.          The design avoids the salient pole pieces required in prior art arrangements.
