Abstract: Abstract Recording Apparatus A recording apparatus for linewise recording information on a moving photoreceptor by means of a plurality of chips on each of which parallel sub-rows of uniformly spaced radiation sources are formed, wherein a shortcoming of prior art apparatus, namely the impossibility to use chips on which even one radiation source only is defect, is overcome.    The apparatus comprises two parallel rows of radiation sources, each row comprising reserve radiation sources that are arranged with corresponding basic radiation sources of the other group in optical parallelism, and connection circuit means for establishing electrical contact with a basic and/or a reserve radiation source (Fig. 5).

Abstract: ABSTRACT OF THE DISCLOSURE                           DRIVE MECHANISM             A drive mechanism comprises a support upon which a drive member is mounted for movement relative to a frame. The drive member comprises first and second elements which are relatively movable, the one of which may be mounted on the other. The elements are interconnected by a resilient member which transmits the drive therethrough, a drive input being coupled to a one element, a drive output to the other element. A detector generates a signal output responsive to relative movement of the elements which may serve to control a drive transmitted through the mechanism. In a preferred embodiment, the support is a rotatable screwed shaft and the first element a traveller thereon upon which the second element is slidably mounted, the elements being interconnected by helical springs.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a combine harvester apparatus having a cutting mechanism apparatus of this invention connected thereto which may be of substantial length.  The cutting mechanism apparatus is divided into three sections being a center platform assembly; a right platform assembly; and a left platform assembly.  Each platform assembly is capable of performing a crop harvesting function as having  1) a reel assembly to direct the crop;  2) a sickle assembly to sever the crop; and  3) an auger assembly to carry the severed crop to a center point for elevation into a combine harvesting machanism.  The right and left platform assemblies are pivotally connected to the center platform assembly and adapted to be raised or lowered manually or automatically to compensate for variances in levels of the terrain.  Numerous special design features are necessary to allow for this vertical movement while maintaining driving forces between the sickle assemblies; auger assemblies; and the reel assemblies.  For example, a special cover reel assembly is provided on each end of the center reel assembly because of gaps created between same and the right and left reel assemblies when raised to an elevated position.

Abstract: ABSTRACT OF THE DISCLOSURE A clip-type electrode for an electrocardiograph includes a pair of clamping plates for being opened and closed relative to each other about a common shaft and having concave surfaces facing each other, an electrode member mounted on one of the clamping plates, and a leaf spring bent into a U-shaped configuration for biasing ends of the clamping plates remote from the common shaft towards each other. Each of the pair of clamping plates has a slot at a position adjacent to the shaft for accommodating the leaf spring passed therethrough, and a plurality of grooves formed in an outer surface thereof and spaced at successively greater distances from the shaft.  One end of the leaf spring is fitted into a one of the plurality of grooves in one of the clamping plates, and the other end of the leaf spring is fitted into one of the plurality of grooves in the other of the clamping plates, the grooves being chosen based upon the thickness of a limb, such as the wrist or ankle of a human body, that is to have the clip-type electrode attached thereto.          The limb can thus be clamped with a prescribed clamping force irrespective of the thickness of the limb.

Abstract: ABSTRACT OF THE DISCLOSURE:                   A method and apparatus  for high speed welding are disclosed wherein a continuous weld is formed at high speed along a member with a plurality of overlapping welds formed by pulses of high density energy from a pulsed high energy  density  welding  device  such  as  an  electronically pulsed gas laser.   The movement of the member being welded is detected in the vicinity of the pulsed laser.  The pulsed laser is  controlled in response to  the detected movement so that  the energy for welding from the pulses per unit length of the member being welded is accurately controlled. The control of the laser involves pulsing of the laser in response  to  the detected movement of the member so  that the pitch of the overlapping welds along the member is subs-tantially constant.   Also,  the power of the laser pulses is  controlled  and  adjusted  in  a predetermined manner  in response to the detected movements.  The high speed movement of  the member is detected by detecting the leading edge of the moving member at or upstream of the pulsed laser and also continuously detecting the position of the moving member at or as it moves past the pulsed laser.  High qua-lity welds can be made in materials at speeds of 22-40 m/min. or more with the method and apparatus.

Abstract: ABSTRACT          Novel self-supporting oxide ceramic materials are produced by the reaction of a molten metal with a vapor phase oxidizing environment using a novel oxidation mechanism.  The process is practiced by creating conditions under which the molten metal  is drawn into and through the oxide reaction product to cause continued growth of oxide at the oxide/atmosphere interface.  Under the special conditions of the process invention, molten metal is transported along certain of the intersections of the oxide crystallites by virtue of a preferred wetting phenomenon, such that interconnected channels of the liquid metal are formed where grain boundaries of relatively high surface energy would otherwise occur in the oxide.  The resulting novel ceramic product consists of an oxide phase which is interconnected largely through relatively low energy grain boundaries and a metal phase (or porosity in place of the metal phase) also at least partially interconnected.

Abstract: ABSTRACT OF THE DISCLOSURE         A device for measuring the winding hardness of a strip, especially a strip of paper, that has been wound into a reel.  The device consists of a mechanism for extracting a slip that has been inserted tight between two coils of the reel of paper with one end extending out of the side of the reel and of a dynamometer that measures the force necessary to extract the slip over a certain distance.  To allow winding hardness to be displayed directly rather than in the form of a graph, the slip-extracting mechanism operates at a constant extracting speed, a pulse generator that is supplied with the resulting force, or with a control signal derived from it, by the dynamometer supplies counting pulses to an up-down counter at a frequency that is proportional to the force, and the slip-extracting mechanism is connected to an odometer that, when it detects equal distances, switches the counter from up to down and stops it.
