Abstract: Abstract of the Disclosure A robotic manipulator has three linearly extensible arms mounted on a frame in a triangular array and carrying at their remote ends a connector inter-face coupling the arms to a tool for manipulating parts to be positioned or for other work.  The structure is such that the location of the connector is deter-mined solely by the lengths of the arms, while its orientation is determined primarily by the angular rotation of the arms, thereby minimizing the computation required to accurately position a tool.  The driving motors for the arms are located at the arm ends adjacent the frame; this minimizes the mass, and thus the inertia, located at the connector end, and enables high acceleration and rapid motion of the connector head and its associated tool.  Further, a three -point suspension for the arms provides high stiffness enabling the system to carry substantial loads at high speed and with good positioning and orientation accuracy.

Abstract: ABSTRACT OF THE DISCLOSURE      Method and apparatus for electrogalvanizing one or both sides of a steel workpiece are disclosed.  A series of insoluble apertured plating anodes are positioned in spaced relation to the workpiece.  When one side is to be plated one or more anodes are preferably mounted above the strip and when both sides are plated, anodes are mounted both above and below the strip.  Solution is pumped through the holes in the anodes to momentarily contact the work-piece and they fall into a sump to be recirculated.          A potential difference between the anode or anodes and the workpiece causes current flow through the electrolyte solution to electroplate the workpiece.          Solution collected by the sump is directed to a reaction station for replenishment of the zinc metal ion.  The solution is then filtered back to a main reservoir tank from which it is again pumped to the plating anodes.

Abstract: ABSTRACT OF THE DISCLOSURE      The cleaning apparatus includes a wheel in the form of a rapidly rotating drum having relatively few blades spaced circumferentially about the periphery thereof and extending radially thereon.  Abrasive material is delivered from a hopper through a slot and is picked up by the blades of the rapidly rotating drum and delivered with extremely high kinetic energy onto the surface to be cleaned.  The apparatus is constructed so that the recovery path of the abrasive material from the surface to be cleaned and the delivery path of the abrasive material directed to the surface to be cleaned are in the same plane of rotation and in the same plane of rotation as the drum.  The recovery path is generally contiguous with the housing of the drum, creating a compact apparatus which utilizes the normal path of movement of the recovered abrasive material.  By providing an apparatus in which the delivery and recovery paths are both essentially in the same plane and in the plane of the rotating drum, the size of the apparatus required is reduced, wear on the components of the apparatus is signifi-cantly reduced, the construction is simplified and the cost is reduced.

Abstract: SILENCE EDITING SPEECH PROCESSOR            Abstract A speech pattern is converted into a sequence of adaptive digital codes.  Intervals of silence in the pattern are detected and a digital code representative of each silence interval is generated.  The adaptive digital codes and the silence interval codes are combined to form a digitally coded signal representative of the pattern.  The conversion of the pattern to adaptive digital codes includes forming a signal corresponding to the adaptation step-size for each digital code.  The silence interval detection includes producing first and second threshold signals.  A silence interval signal is initiated when the adaptation step size corresponding signal diminishes below the first threshold and the silence interval is terminated when the adaptation step-size corresponding signal increases above the second threshold after the silence interval initiation.

Abstract: A b s t r a c t The machine for the manufacture of cams from sheet metal has a press stern (10) which is surrounded by a number of ram assemblies (11) carrying dies (12) coopera-ting with punches (13) attached to bolster (14) of circular shape. A cyclindrical cam (21) cooperates with ram assem-blies (11) through follower rollers (22, 23). The cam is driven by gears (32, 33) and a crankshaft (36).              The corresponding transfer mechanism comprises a-transfer ring (43) provided with three mounting pins (42), two idling arms (44) and a driving crank (41). As the shaft (40) rotates, the ring (43) gyrates  about the center of the press stern (10), the two idling arms (44) always maintaining a parallel relationship to the crank (41). Six pockets (P1 to P6) are attached to the transfer ring (43) - according to Fig. 8-1 one pocket (1) collects a blank from the supply conveyor, whereas another pocket (2) makes contact with the component in the first tool (1) etc. The interaction between transfer pockets of the ring (43) and the locating rings attached to the tools (T1 to T5) ensures complete control of the components during transfer, nest means being provided at each tool including a plurality of spaced prongs cooperating with spaced fingers provided on each pocket (P1 to P6). Fingers and prongs are arranged in such a manner that the fingers of an empty pocket member pass between the prongs of the nest means and remove a component located at the tool station.              The components are thus advanced from one tool station to another along a circular path, the tools being operated consecutively by said cam (21) and thereby sub-jected to a periodical reciprocating action.
