Abstract: Abstract of the Disclosure Current channeling through stacks of polycrystalline varistor devices for high voltage surge protection applications is prevented by applying patterned electrodes to the varistor elements of the stack.  The patterning of the electrodes prevents the formation of an equi-potential surface over the interface between elements of the stack.  Therefore, currents are prevented from channeling through the preferential current paths in each element of the stack and more equal current distribution through the devices is provided resulting in substantially increased reliability of the stack and its elements.

Abstract: ABSTRACT              In an electronic musical instrument with two tone generators of which the frequency of the tones produced by them is substantially constant for the first generator a and for the second generator not until after a final value is reached which corresponds to the frequency of the corres-ponding tone of the first generator, the frequency of the first generator is applied to a first input and that of the second generator to a second input of a frequency comparator circuit, whose output is connected to a control input of the second generator via  control device. This ensures that the repeated readjustments of the control quantities necessary in known instruments are no longer necessary.

Abstract: METHOD AND APPARATUS FOR COUPLING          PIPE OR THE LIKE     ABSTRACT OF THE DISCLOSURE         Method and apparatus for connecting the ends of pipes or the like.  The apparatus includes a pair of coupling members, each being mountable at one end thereof to the end of one of the pipes which are to be connected.  One of the coupling members has attached at the other end thereof an annular outwardly extend-ing flange having forward and rearward sides.  The flange is preferably dovetailed in cross-section.  The other member is provided with a housing for receiving the flange in mating and locking engagement therewith.  A plurality of cam members are carried by the housing and are radially movable between a retracted position in which the flange is receivable by the housing and an extended position in which the cam members are engaged with the rearward side of the flange to drive it into locking engagement with the housing.  Means are also provided for releasably tying or interlocking the housing to the other coupling so as to prevent undesired radial outward deformation of the housing upon actuation of the cam members when the two coupling members are coupled together.  Means such as hydraulic cylinder assemblies are also provided for moving the cam members between the retracted position to the extended position to accomplish the aforesaid joining and interlocking of the coupling members.

Abstract: Abstract of the Disclosure A skimming separator for scavenging liquid and solid floating matter from the face of a body of liquid, wherein traction surfaced contiguous cylinders counter-rotate to frictionally convey a contacting layer of liquid and proximate flotage matter thereon directly into a natural floating reser-voir formed by the cylinders and the body of liquid below.  Within the reservoir, conveyed solid flotage is selectively either entrapped by a guard screen, or, by adjustment of the screen, abraded by the traction surface into a floating liquified slurry for disposal along with the conveyed originally liquid flotage by pump means.  In passing through the nip of the contiguous cylinders, the traction surface is regenerated for reuse in the subsequent recirculation cycle.  The traction surfaced material ranges from soft cellular materials to very hard abrasive coated materials as commonly used for industrial grinding purposes, and includes granular grit of discrete magnetic particle material which is movably retained by a magnetized base material, whereby the magnetic grit traction surface can be quickly adjusted by the addition or removal of material to meet immediate need during changing conditions in the scavenging operation.  A compactor is included to compress and reduce the bulk of solid floating material such as metal, glass, and plastic foam materials, sea-weed, kelp, lilly pads, and the like.
