Title: Method and apparatus for the production of sized apertures
Inventor: BAKER GEORGE E
IPC: B23H7/28
Filed: 1989-10-24
Abstract: ABSTRACT          TITLE: METHOD AND APPARATUS FOR THE PRODUCTION OF                            APERTURES      A method and apparatus for the production of a plurality of apertures in one or more components, such as fuel injector nozzles of precisely controlled throughput, has the apertures produced by EDM.  The apparatus com-prises an electrode (2), the lateral dimensions of which are less than those of the apertures to be produced and means (9, 11,) for producing relative orbital movement between the electrode (2) and the component during machi-ning of the latter to produce an aperture of the required lateral dimensions.  The orbital movement is controlled by signals generated in response to measurement of the flow characteristics of an aperture already machined and comparison of such flow characteristics with the desired flow characteristics.  The orbital movement may be pro-vided using piezo-electric transducers (9,  11) or servo-motors to convert the control signals into orbital mo-tion.

Title: Spherical cock with ball-shaped metallic ceramic stopcock
Inventor: HARTMANN WERNER
IPC: F16K5/06
Filed: 1989-12-08
Abstract: Abstract A spherical cock has a ball-shaped, metallic or ceramic stopcock arrayed with loose or fixed axle-end pivots or floatingly arrayed within a casing.  The stopcock centres itself in the longitudinal and vertical axis between metallic or ceramic surfaces of two seating frames.  These frames are mounted in the valve casing so that the spherical surface of the stopcock bears directly on said surfaces of said frames without the use of soft packing.  The sealing surfaces of the stopcock and those of the frames are coated or tempered to be hard and to have high abrasion resistance.

Filed: 1990-02-07
Abstract: The functions of two virtual operating systems (e.g., S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system.  One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated from 1 to 16 megabytes of contiguous storage from the S/88 main storage.  Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques.  The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space.  The S/88 Operating System is the master over all system hardware and I/O devices.  The S/88 processors access the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations.  The S/88 and S/370 peer processor pairs execute their respective Operating Systems in a single system environment without significant rewriting of either operating system.  Neither operating system is aware of the other operating system nor the other processor pairs.

Abstract: TITLE CHEMICAL TREATMENT OF FORAGE                INVENTOR Leslie J. Halliday ABSTRACT OF THE DISCLOSURE         The effect of different chemical treatments applied to barley straws, timothy and alfalfa hays were determined.          Treatments consisted of four concentrations of hydrogen per-oxide (3%, 5%, 7% and 9%) in combination with 4% ethanolamine with or without the addition of sodium hydroxide, which was added to increase the pH.  The ability of each treatment to improve the nutritive value of the forage and their effect on rumen function was ascertained.
Patent CA-2011326-A1 (CA)
IPC: G06T1/00
Filed: 1990-03-02
Abstract: The shading correction is performed with respect to a signal "A" indicative of the image density read by an optical read device in accordance with a reference signal "B".  Both the signals "A" and "B" consist of n bits.  An inputted signal having an initial value "A" is doubled by a multiplier when A?B and B?0.  A subtracter subtracts the reference signal "B" from a signal "X" outputted from the multiplier and discriminates whether or not a signal "X-B" is negative.  An S/P conversion register doubles an inte-grated value "S" having an initial value "0" and changes the integrated value from "S" to "2S" when the signal "X-B" is negative.  In contrast, when the signal "X-B" is not nega-tive,  the S/P conversion register adds  "1"  to  "2S"  and changes the integrated value from "S" to "2S+1".  The signal "X" outputted from the multiplier is again inputted into the multiplier when the signal "X-B" is negative.  Alternative-ly, the multiplier receives the signal "X-B" outputted from the subtracter when the signal "X-B" is not negative.  The above procedure is repeated n times.  The last integrated value outputted from the S/P conversion register is equal to or approximately equal to a value obtained by an expression "S=A(2n-1)/B", and therefore, the former can be regarded as a shading correction signal.

Filed: 1990-05-11
Abstract: Abstract of the Disclosure The activation of glycerol ester hydrolases, toward triglyceride oils, is correlated to the molar ratio of total triglyceride to surfactant concentrations in the test solution.   This ratio dependency,  when considered   in  laundry  compositions,   allows   for predictable and improved utilization of these enzymes in the hydrolysis of triglyceride stains.  A particularly preferred  enzyme  for  this  use  is  isolatable  from Pseudomonas  putida  ATCC  53552.    This  enzyme,  or hydrolase,  has sufficient hydrolysis  activity  in a laundering solution to hydrolyze at least about 5 wt. % of total triglyceride stains in a laundering solution within about 15 minutes at about 25°C.

Abstract: An optical fiber splicing device (20) includes a glass cylindrically shaped capillary tube member (24) having a passageway formed therethrough eccentrically of the longitudinal axis of the capillary tube member. The capillary tube member is provided with a slot (86) such that a portion of the passageway in the form of a groove (88) extends across a planar surface (87) formed by the slot. The capillary tube member is mounted in a housing (22) which is made of a material and formed to provide a lens opposite to the slot to facilitate visual inspection of ends of end portions of two optical fibers which are positioned in the groove. A spring clamp (26) is mounted to the housing in a first position spaced from the planar surface to allow insertion of fiber end portions into the groove. The clamp is moveable to a second position where it is secured to the housing in a position which causes a portion of the clamp to engage the fiber end portions along at least a portion of the planar surface to hold the fiber end portions in secured alignment with each other.

Title: Staged three-way conversion catalyst and method of using the same
Inventor: RUDY WAYNE M
IPC: B01J35/02
Filed: 1990-10-11
Abstract: ABSTRACT OF THE DISCLOSURE A catalyst composition has an upstream stage and a downstream stage, the upstream stage containing a catalytic material which is different from the catalytic material contained on the downstream stage and is characterized by having a low ignition temperature, e.g., 350°C to less than 400°C, for the substantially simultaneous conversion of HC, CO and NOx pollutants contained in, e.g., the exhaust of an automobile engine operating at a substantially stoichio-metric air-to-fuel weight ratio.  The downstream catalytic material is characterized by having a higher conversion efficiency for substantially simultaneous conversion of HC, CO and NOx than the upstream catalytic material at elevated operation temperatures which may be, for example, from about 400 to 800°C.  The method of the invention includes passing a gaseous exhaust stream containing HC, CO and NOx pollu-tants sequentially through first the upstream and then through the downstream catalytic materials.
