Abstract: ABSTRACT         A resilient bearing (1;35) for damping oscillations of equipment, in particular vehicle engines, avoids resonance step-ups at approximately 12 Hz.  In this bearing, damping fluid is pumped from a working chamber (22) over spherical flow surfaces of suitable surface configurations (30 - 32) or flow resistance of a membrane (50) into an equalizer chamber (23).  Operating noise is avoided by decoupled support of the partition and by free travel of the membrane (16; 41; 50).  In order to prevent dynamic stiff-ening at higher frequencies the equalizing chamber (23) with an integrated choke system is additionally elastically supported in the bearing housing (4).

Abstract: 51,993 ABSTRACT OF THE INVENTION           The invention provides an improved welding torch wrist and improved elongated axis post member for use with an industrial manipulator or the like.  The improved wrist is adapted to be mounted onto the industrial manipulator typical-ly in the spaced relationship therewith by means of an axis post.  The welding torch wrist includes a housing adapted to be mounted onto the industrial manipulator, a torch holding member which is operably associated with the  housing for controlled movement about a first axis through a predeter-mined arc of travel and a drive unit including a DC servo motor coupled to a harmonic drive mounted in the housing for affecting the aforedescribed controlled movement.  The drive unit is mounted in the housing so as to be radially disposed relative to the arc of travel of the torch holding member. This end line construction is made possible through the use of a pair of beveled gears.  One of the pair of beveled gears is a spring loaded split bevel antibacklash gear which totally eliminates gear backlash.  This is particularly critical during the torch tip weave affected during welding operations. The improved axis post provides extended welding capabilities to the improved wrist by permitting deep vessel welding oper-ations.  The improved post includes a pair of thin wall tub-ular members which are welded together and provided with add-itional support members.  The axis post is so configured to orient the welding torch toward the "Z" axis of an industrial manipulator.

Abstract: Abstract:    A bi-planar pontoon paravane (20) is towed by a marine vessel and controls the depth and position of a towed seismic source array.  The bi-planar pontoon paravane is made up of a buoyant bridge (21) with right (22) and left (23) wings attached to the long sides of the bridge, the wings projecting into the water and, in concert, providing a side force.  The paravane is towed by a tow line (11) connected to an adjustable bridle (81) which in turn is connected to the paravane.  Remote adjustment of the bridle is provided by an hydraulic valve on the vessel controlling an hydraulic motor (61) and gear arrangement (62) on the paravane to adjust the bridle.  Adjustment of the bridle adjusts the angle of attack of the paravane.  The paravane provides a housing formed below the bridge and between the two wings for housing the seismic source array.  A boom on the vessel is attached to the seismic source array, through the bridge, when the assembly is to be placed in or removed from the water.  To remove the assembly, the boom pulls the seismic source array until it enters the housing and then lifts both the seismic source array and the paravane out of the water.  Placing the assembly in the water is simply the reverse with the seismic source array being supported by the paravane at a desired depth by action of a locking mechanism in the paravane.  A nose plane is positioned in the front of the paravane, below the bridge and between the right and left wings and angled relative to the horizontal to minimize diving  of the paravane.

Abstract: ABSTRACT          HIGH CONTRAST PHOTORESIST DEVELOPER    A positive photoresist metal ion aqueous developer is provided that gives a high contrast to the photo-resist.     The developer disclosed comprises a formulation of aqueous alkali-base such as potassium hydroxide and a carboxylated surfactant.  The incorporation of the car-boxylated surfactant provides the unexpected increase in the contrast of the photoresist.  The addition of the carboxylated surfactant increases the gamma from a typi-cal photoresist gamma (.gamma.) of 3 or less to a gamma greater than 5.     The high contrast photoresist provides linewidth control and affords improved process latitude in photo-resist imaging.  The linewidth control is particularly critical in cases where fine lines are to be defined in the resist that covers steps of topography on the coated substrate.  The higher the contrast, the less affected the resist by the topography, provided the exposure is adequate to expose the resist.  The process latitude afforded by the high contrast is a result of the ability to over develop (develop longer) the exposed resist without affecting the unexposed resist in the adjacent areas.

Abstract: Abstract of the Disclosure A vacuum cleaner housing possesses two guide means on the inner side of the end housing wall with a suction port therein in order to receive the board flange of a dust bag adjacent to the lateral housing wall. The guide means comprise guide rails each with a ramp-like wall, extending towards said housing wall, and guide ribs which are located in the lower part of the housing wall and have a slope opposite to that of the ramp-like walls. They are so shaped as to allow the board flange to be inserted between them and the walls. On introduction of such a board flange of a dust bag its lower end section is bent along a prepared line of bending, which has been formed in the lower part of the board flange parallel to its lower side. Accordingly the board flange is so firmly held in place that it is not bent by the suction force to which it is exposed. The vacuum cleaner housing is further made with a cover stop which prevents closure of the cover unless a dust bag has been previously placed in the vacuum cleaner housing.
