Abstract: PERIPHERAL ATTACHMENT INTERFACE FOR I/O           CONTROLLER HAVING CYCLE STEAL AND OFF-LINE MODES     Abstract This I/O interface permits attachment of a data processing system to devices having different "handshaking" protocols and bit-parallel data exchange capacities.  Handshaking control circuits permit the system to communicate with devices variously in pulsed and interlocked modes.  Timer circuits provide a variety of different time reference signals for transfer to devices.  Switching options associated with the timer permit selective use of timer outputs as pulsed mode handshaking functions.  A counter circuit and associated interface port permit the system to count events associated with device-originated pulses.  A switching option permits the counter incrementing operations to be governed by timer outputs.  The interface also contains path selection lines.  In one mode these lines define high speed exchange of data between a primary system processor and devices in various bit-parallel formats and over various buses designatable by a systems processor.  In another mode these lines permit a secondary system processor to exchange data with a series of multiplexed devices.  Collectively, the interface lines have a symmetrical configuration which permits their use for direct interconnection of two data processing systems without the expense of additional "channel to channel" adaptation.

Abstract: ABSTRACT Crosslinked poly(parabanic acid) is obtained by heating poly(parabanic acid) at a temperature in the range of 200-300°C in the presence of a crosslinking amount of a sulfonic acid, ester or salt thereof.  The presence of the sulfonic acid, ester or salt thereof provides for a shorter curing time as compared with thermal crosslinking in the absence of the sulfonic acid, ester or salt thereof, thereby avoiding oxidative degradation.  The crosslinked poly(parabanic acids) are useful for the production of magnetic tapes, films for use in flexible printed circuits, cable wraps, fibers such as tire cord fibers and the like.

Abstract: ABSTRACT OF THE DISCLOSURE An improved mainshaft gear retainer assembly (66,   68)   for   a   multiple   countershaft   (18,   18A) transmission  (10)  having  at  least one pair of  floating mainshaft  gears  (44-46,  48-50)  positioned  axially close together  in groups of  two and clutchable to a mainshaft (40) one at a time by positive clutches  (54, 56, 58)  is provided. The  improved mainshaft gear retainer  assembly prevents  axial  movement  of  the  two  closely  positioned gears and reacts the axial forces on a clutched one of the mainshaft gears toward and away from the other mainshaft gear  to  the  mainshaft  by  means  of  thrust  surfaces (46D-82B,82C-78C,  78D-74B,  74C-70,  94B-82C  or  82B-84) which are all rotating, or tending to rotate, at the same speed as the clutched mainshaft gear  and the mainshaft. The gear  retainer comprises  relatively simple components and allows easy assembly and disassembly of the mainshaft gears and gear retainers from the mainshaft.  Each of the closely  spaced  mainshaft  gears  and  certain  associated retainer components defines a subassembly (44, 76 and 90) and  (46,  82 and 94)  which is independently assembled to and removed from the mainhaft assembly (20).  The improved retainer  assembly  components  are  all  received  in  the circumferential space defined by the root diameter  (42A) of the mainshaft splines  (42)  and the root diameter  (44B and 46B) of the gear internal clutch teeth (44A and 46A).

Abstract: ABSTRACT OF THE DISCLOSURE         A plurality of discrete small cooling surfaces are arrayed on the surface of a journally or movablely received heat extracting member in both the axial and rotational directions.       These discrete small cooling surfaces can be formed by a plurality of one set of parallel grooves formed between two axial ends and obliquely to the axial ends having been crossed by a plurality of the other set of parallel grooves formed in a similar manner but in different direction.         An opening of nozzle means are directed toward the outer peripheral surface of the heat extracting member.         A continuing stream of molten material is projected upon the discrete small cooling surfaces of the rotating heat extracting member, thereby the heat of the molten material is extracted by each of these discrete small surface and solidifies on it in a discrete flake particle.         Since the discrete small cooling surfaces are formed in a number of arrays extending in both axial and rotational direction by crossing the one set of grooves with the other set of grooves, opening or openings of the nozzle means can be extended in long length in the axial direction of the heat extracting member or can be arranged as a plurality of nozzles in same direction.         Accordingly, the molten material can be applied concurrently onto a plurality of discrete small cooling surface.         By virtue of the apparatus of the construction, flake particles can be obtaiined at a greatly increased production efficiency.

Abstract: HANDLE-OPERATED DOOR LOCK               WITH LATCH-OPERATOR OVERRIDE                         Abstract A handle-operated lock for use on a sliding door has hook-shaped, rotary latch bolts which project from opposite sides of  a  housing  for  selectively  engaging  spaced  strikes  to selectively retain the sliding door in open or closed positions.          A compression coil  spring  is  carried within  the housing  for biasing the latch bolts toward their latched positions.  Inside and outside rotary handles are provided for selectively rotating the latch bolts to unlatch them in opposition to the action of the spring.  Inner and outer rotary tumblers are provided within the housing to drivingly connect the rotary handles with the rotary latch bolts.  A slidable latch-operator is provided near the inside handle for movement between a locked position wherein it prevents rotation of the outer tumbler to disable the outside handle  from operating  either  of  the  bolts,  and  an  unlocked position wherein it permits the outside handle to operate the latch bolts.  A latch-operator override mechanism is provided for moving  the  latch-operator  to  its  unlocked position when  the inside handle is operated at a time when the latch-operator is in its locked position.  The lock housing is formed from a pair of stamped metal plates which are interconnected both by spot welds and by a plurality of tabs which project from one of the plates and extend into interfitting engagement within recess formations provided on the other of the plates.   Portions of the recess formations are utilized to position the spring properly between portions of the latch bolts, and to guide the movement of the latch operator between its locked and unlocked positions.  The handles have independently rotatable shafts which extend along a common axis.  The tumblers and the lock bolts also rotate about the   common   axis   and   cooperate   to   provide   a   rugged, tamper-resistant assembly.

Abstract: Abstract of the Disclosure An array of optical fibers is precisely positioned in spaced apart channels in a head when a metal, such as tin-lead solder, is used to fix the fibers in the channel.  A glass fiber is first ion plated with about one micrometer of a metal such as nickel which is wetted by the solder.  The fiber is then placed loosely in a channel in a metal holder and solder is infiltrated to surround and adhere to the fiber.  Strain on the glass fiber where it exits its holder channel is alleviated when the polymer jacket is also ion plated with metal and is bonded to the holder by solder.

Abstract: Abstract of the Disclosure Antigenicity of streptococcal preparations useful for inducing anti-streptococcal immunity in animals can be determined using a combining power technique.  Method involves incubating serial dilutions of the antigen prepar-ation with known amounts of anti-streptococcal antiserum, thereby lessening, in serial manner, the combining power of the antiserum.  The serial reaction products are then incubated with serial dilutions of streptococcal prepara-tions having known activity and the effects of the serial reaction products on such activity are then determined by in vivo means.  Those determinations can be related to a standard for determining potency of the streptococcal preparation.  Assay technique is especially useful in determining potency of Streptococcus equi bacterins or bacterin derivatives.
