Abstract: ABSTRACT OF THE DISCLOSURE A data processing system comprises a data processing unit coupled to a cache unit which couples to a main store.  The cache unit includes a cache store organized into a plurality of levels, each for storing blocks of information in the form of data and instructions.  The cache unit further includes control apparatus, an instruction buffer for storing instructions received from main store and a transit block buffer comprising a plurality of locations for storing read commands.  The control apparatus includes a plurality  of groups of bit storage elements corresponding to the number of transit buffer locations.  Each group includes at least a pair of instruction fetch indicator elements which are operatively connected to control the writing of first and second blocks of instructions into the instruction buffer.  Each time a read command specifying the fetch-ing of instructions of either a first or second block is received from the processing unit, the flag storage element associated with the transit block buffer location into which the read command is loaded is set to a binary ONE state while the corresponding ones of the flag storage elements associated with the other locations storing outstanding read commands specifying instruction fetches are reset to binary ZEROS.  This permits only those instructions received from main store in response to that read command to be loaded into a specified sec-tion of the instruction buffer for enabling overlaps in processing several commands specifying instruction fetch operations.

Abstract: Abstract of the Disclosure An electromechanical counter which includes a clapper which is movable in response to an electric signal is mounted for pivotal movement about a first axis.  A verge is mounted for pivotal movement about a second axis parallel to and spaced from the first and is drive connected to a counter.  The clapper and verge are interconnected at a point intermediate the first and second axis and pivotal movement of the clapper in one direc-tion will cause pivotal movement of the verge in the opposite direction. The centers of gravity of the clapper and the verge are respectively coin-cident with the first and second axes.  The counter is thereby rendered insensitive to mechanical shocks.

Abstract: ABSTRACT OF THE DISCLOSURE        A method for warm forging a cup-shaped piece is dis-closed.  In warm forging a blank is heated between 400 and 800°C and is inserted within a die having a cross sectional area substantially larger than that of the blank.  The ends of the blank are clamped between a recess in the die and a recess in an upsetting punch and the upsetting punch compresses the blank until its sides become sufficiently bulged to almost touch, or touch, the sides of the die.  The upsetting punch is then removed and a backward extruding punch is press fitted into the bulged blank and the blank is extruded to form a cup.          The extrusion punch is lubricated and cooled by lubricant and coolant applicators at a position remote from the die so that the blank is not prematurely cooled by the coolant.

Abstract: ABSTRACT OF THE DISCLOSURE A clamp consists of a clamp bolt cooperating with an arcuate saddle which together encircle an article to be clamped, the clamp bolt constituting tightening means for tightening the clamp on the article.  The saddle terminates in two tubular portions which receive the bolt and provide respective bearing surfaces for the head and the clamping nut, or the two clamping nuts, depending on the nature of the bolt.  The saddle is formed by stamping from a rectangular blank of thin flat sheet metal, the blank being formed into a hollow tube with the longer edges in contact with one another and bent to the necessary arcuate shape, the joint between the longer edges being disposed in the radially inner con-cave face so that it contacts the article to be clamped.  The radially-outer central tube wall portion preferably is collapsed into contact with the radially-inner central tube wall portion so as to form a double-walled channel-section saddle with the said tubular portions integral therewith formed by the uncollapsed tube ends.  Preferably the channel is of semi-circular transverse cross section.
