Abstract: ABSTRACT OF DISCLOSURE        In a preferred embodiment, a gear drive mechanism includes a non-driving interval in the reverse direction of rotation of the handle of a ratchet wrench.  Within that interval handle engagement with a toggle-type switch can occur for reversing ratcheting direction. This handle engagement of the ratcheting mechanism being by way  of  handle  twistable  out  of  alignment  with  the mounting structure of the handle portion of the wrench.          In  this arrangement non-circular circumscribing inside wall surfaces of the handle (as viewed in transverse cross-section)  engages and wedges a roller against the rounded surface of the drive shaft.  Thus, while the roller is wedged, reverse direction turning of the handle causes the drive shaft to turn to thereby flip the toggle-like  switch  mechanism,  thereby  reversing  the ratcheting direction of the ratchet wrench.

Abstract: ABSTRACT OF THE DISCLOSURE    A large diameter stud and a method and apparatus for welding same are provided.  The large diameter stud has a protruding tip at a weldable end thereof containing a solid rod-like body of flux.  A ceramic ferrule which can have a two-step cavity surrounds the weldable end portion of the stud when engaged with the work-piece to which it is to be welded.  An arc blow coil surrounds the ferrule and is spaced therefrom with powdered flux there-between and above the ferrule.  The arc blow coil is attached to adjustable legs of a welding tool and has a weight thereon to aid in supporting the welding tool upright on the workpiece during the welding operation.  In the welding cycle, a relatively low weld current is used for the main welding arc and is maintained for an extending period of time.  Current through the arc blow coil is initiated when the welding cycle begins and is gradually increased to a maximum at an intermediate point in the welding cycle.

Abstract: ADAPTIVELY CALIBRATED SENSING MECHANISM      FOR AN ENGINE DEMAND DEVICE            Abstract of the Disclosure A position indication derived from the output signal of an engine demand device sensor is compensated for errors which tend to expand or contract the range of such output signal. The signal is compared to previously stored upper and lower reference values nominally corresponding to the limit positions of the demand device, and the position indication is derived in accordance with such comparison.  The compensation is achieved by altering the previously stored upper and lower reference values at the initiation of each period of vehicle operation, in a sense to contract the range of output signals defined thereby, and by replacing the upper or lower reference values with the sensor output signal value during the ensuing period of vehicle operation if the sensor output signal value is greater or less than the upper or lower reference values, respectively.

Abstract: ABSTRACT OF THE DISCLOSURE A direct memory access (DMA) system with a single bus architecture for controlling data transfers and storage between plural digital processors and plural Input/Output devices.  Limiters are included for disabling access to the bus of a processor whose access time exceeds a predetermined time interval.  A time governor is included to suppress processor access to the bus when total processor access time in a data communication cycle has exceeded a predetermined time interval.  The input and output devices are coupled to the bus through interface isolation circuits that prevent faults in the input and output devices from propagating to the system to cause total system failure.  An input or output device fault can only result in erroneous data being provided to a location of the DMA memory reserved for the faulted device.  The DMA memory is protected by a Write-Protect Decoding Circuit that prevents processor writing into prohibited areas of the memory.

Abstract: ABSTRACT: "Method of manufacturing a semiconductor device,in which a silicon slice is locally provided with field oxide with channel stopper".           A method of manufacturing a semiconductor device, in which a silicon slice (?) is locally provided with field oxide (10, 30) with a subjacent channel stopper zone (12, 32), which are formed during the same oxidizing heat treatment. The field oxide layer (10, 30) then formed is removed in part by an etching treatment, a thinner and smaller field oxide layer (11, 31) being formed. The temperature at which the heat treatment is carried out is chosen so that lateral diffusion (15, 35) of the dopant forming the channel stopper zone (12, 32) extends in lateral direction practically over the same distance as the reduced field oxide layer (11, 31). Thus, it is achieved that, for example, for the manufacture of a MOS transistor an oxidation mask (7) having substantially the same width as a channel zone (17) to be formed can be used.

Abstract: CLAMPING DEVICE                           ABSTRACT  This invention is an improved concept of the clamp shown in U. S. No. 3,736,629, as issued June 5, 1973.  This clamping device has two C-shaped arms, each of which is an assembly of two plate-like members of sheet metal.  These two arm assem-blies are pivotally retained at one end, with the plate like members in an overlay condition.  A pivot pin has an enlarged center portion which acts as a spacer and has two eccentric cam areas sized and spaced to actuate apertures formed in one of the arm pairs.  Shouldered rivets retain these arm assem-blies in spaced array and a stop pin secured in this pivot pin has a length sufficient to engage a secured rivet.  At one limit of movement of the stop pin, the cam areas move one arm assembly to a maximum clamping force and, at the other limit of movement of the stop pin, the cam areas are in a reduced-force application.  Trunnion blocks are pivotally retained in each arm, with one block having through threads and the other block having a smooth bore adapted to retain a socket-headed cap screw whose threaded portion is compatibly disposed in the threaded trunnion.  Rotation of this screw causes jaw ends having pivoted clamp pads to be brought to and away from each other.  The members of this clamp are of metal and the pivot pin and clamp pads may be made by a screw machine and then heat-treated.
