Abstract: ABSTRACT OF THE DISCLOSURE A phototypesetter is disclosed having a stepping motor which actuates an escapement carriage coupled to an elongated carriage driving member. A projection lens carriage and a collimating lens carriage are selectively electromagnetically coupled to the elongated driving member, thereby to project images of varying character sizes through a focusing lens coupled to the escapement carriage, which sequentially projects focused character images across a photosensitive film on a line by line basis. A track select mirror is also selectively electromagnetically coupled to the elongated driving member for selectively projecting one of a plurality of tracks bearing characters of differing fonts carried by a rotatable font carrier element. A group of custom-ized lens carriage positioning control codes and customized sizing codes, unique for equine phototypesetter as a function of lens parameter variations, are stored within a size dictionary and a particular set, associated with the character size being typeset is read out of the dictionary and is employed to control the customized positioning of the lens carriages and image (film) positioning stepping motors. A novel technique is also disclosed whereby a customized group of the above-mentioned codes is rapidly and easily generated by an iterative image inspection process for each particular phototypesetter during manufacture.

Abstract: Abstract of the Disclosure A piston ring is to be mounted in a groove in a piston.  The piston ring has sidewalls for engaging sidewalls of the piston ring groove.  Each of the sidewalls of the piston ring  is hardened in respective localized areas.  The localized areas each include a band of hardened material extending around each respective sidewall of the piston ring near the outer periphery of the piston ring.  The hardened areas terminate short of the outer periphery of the piston ring.  The piston ring due to the termination of the hardened areas short of the outer periphery of the piston ring has  unhardened side surface areas immediately adjacent the outer periphery thereof for location adjacent the areas  of the piston ring groove at the outer periphery of the piston.  The localized areas are hardened by moving a piston ring blank relative to a laser beam, after the piston ring blank is machined.

Abstract: ABSTRACT OF THE DISCLOSURE             The detailed embodiment associates access registers (AR's) with the general purpose registers (GPR's) in a data processor.  The AR's are each loaded with a unique STD (segment table descriptor).  The STD comprises a segment table address in main storage and a segment table length field.  There are 15 AR's associated respectively with 15 GPR's in a processor to define a subset of up to 15 data address spaces.  The STD in an AR is selected for address translation when the associated GPR is selected as a storage operand base register, such as being the GPR selected by the B-field in an IBM System/370 instruction.  The invention allows each AR to specify that it does not use the STD in its associated AR to define its data address space, but instead uses the STD in the program address space AR. However, the STD content of an AR is not selected for an address translation if the associated GPR is selected for a purpose other than as a storage operand base register, such as if a GPR is selected as an index (X) register or as a data source or sink register (R) for an instruction.  A sixteenth AR may be provided to define and control the executing program address space, which may also contain data.             The embodiment obtains authority and other control for access to and use of the content in each address space by also associating an AR Control Vector (ARCV) register with each AR.

Abstract: ABSTRACT        "METHOD OF AND APPARATUS FOR TRANSMITTING  DATA IN A SYNCHRONOUS DATA NETWORK"     Summary Terminal devices El to En are connected via a t.d.m. arrangement MX to a peripherai node PK of the network. A multiplexer Ml or M2 forms a multiplex frame from a plurality of data envelopes (comprising data bits and control bits) supplied via input data channels (e.g.          Kl to Kn in the case of Ml). The synchronising bits (and possibly some of the status bits) of the control bits are substituted by assignment bits indicating the envelope/ data channel assignment. The data bits can be grouped consecutively in the frame or can be separated into groups by assignment bits distributed through the frame. The corresponding demultiplexer D2 or Dl receives the multiplex signal and distributes the data bits into envelopes assigned to data channels in dependence on the associated assignment bits.

Abstract: ABSTRACT    "MAGNETIC BRUSH DEVELOPER UNIT FOR PHOTOCOPIER"     A magnetic brush developer unit has a toner sump below the level of the magnetic brush supporting roller-shell combination and a magnetic pump rotor rotatable in the bottom of the sump to agitate toner and to return toner to a location from which it is attracted onto the shell of the magnetic brush roller.          A scraper blade is effective to remove substantially all the circulating brush-forming toner from the shell and to cause at least a part of the removed toner to fall into the sump to be pumped back up by the magnetic pump rotor.  An optional second scraper blade, directed in the opposite direction from that of the first scraper blade, removes any lumps of agglomerated toner which may be moving countercurrent to the main magnetic brush-forming toner mass.

Abstract: ABSTRACT         A belt printing mechanism has endless type belts (1, 2, 3, 4) disposed parallel to one another and which carry print types (S) on their outer surfaces,  The type belts are each led round an adjusting wheel (6) and a star wheel (8) rotatable about a shaft (7).  A catch mechanism (25), which is held in positive engagement with the star wheels and holds these in  a predetermined detent position, prevents free rotation of the star wheels.  For printing multi-digit characters the print types to be printed from adjacently disposed type belts must be brought into a predetermined printing position, and to produce a clean imprint it must be ensured that these print types are exactly registered.  To achieve this the catch mechanism has for each star wheel a spring tongue (26) which contacts the portion of the peripheral surface of the star wheel extending between two adjacent corners of the star wheel at at least two spaced-apart points and the plane of which forms an acute angle with the plane in which the star wheel rotates about its shaft.  When adjusting the type belts, the catch mechanism produces force peaks which can be clearly felt by the operator and which make it easier for him to bring *he print types in the predetermined printing position.
