Abstract: Invention:  X-Ray Image Equipment Inventor:            Abstract of the Invention Soft x-ray radiation, which has a lower level of radiation, is transmitted to a target (i.e., the breast).  The transmitted image of the target is refined through various computerized processes.  All data is stored in a multiple image memory or filed in a laser having a large memory capacity.       Stored images can be viewed on a TV monitor or recalled and interfaced to a host computer.  Accordingly, the present invention is designed for mass-screening.  The whole sequence of data acquisition and processing is controlled by an operation controller, which also controls the accelerating voltage of the soft x-ray radiation.  The equipment is not limited for use in detecting breast cancer and is equally adapted in examining infants or others who cannot tolerate large or heavy radiation dosages.

Title: Multiprocessor load sharing arrangement
Inventor: DEBRULER DENNIS L
IPC: G06F9/50
Filed: 1989-03-30
Granted: 1993-05-25
Abstract: Abstract A method and apparatus for allocating work requests among a plurality of processors attached to a data ring. Each processor has an interface for communicating with the data ring. The interface for each work request accepting processor has a memory defining a plurality of destination addresses for which the associated processor will accept work requests. Each type of work request has several destination addresses corresponding to different priority levels. If that processor becomes too heavily loaded, it will delete one or more of the destination addresses for which the interface will accept work requests. Such deletions result in the processor only accepting higher priority requests for a class of work requests. Work request generating processors detect work request messages which have not been accepted when they return on the ring. Such messages are then retransmitted at a higher priority, and with a longer delay between consecutive transmissions of the work request message. Advantageously, such an arrangement permits each processor to regulate its own load based on its own measurements of work activity, while permitting repeated attempts to get each work request accepted.

Title: Detersive article
Inventor: CIALLELLA LORETTA K
IPC: C11D17/04
Filed: 1989-04-10
Granted: 1993-06-15
Abstract: ABSTRACT OF THE DISCLOSURE:           A detersive article, useful for charging an auto-matic washing machine with particulate built synthetic organic detergent composition, includes a detersive charge of such particulate composition in a closed container or packet which is formed by sealing about such composition a sheet or sheets of readily water dispersible water soluble cellulose compound and cellulose fibers, which is coated and/or covered or laminated with water soluble polyvinyl alcohol on interior surfaces thereof.  The packet material dissolves or disperses rapidly when the packet is added to wash water in an automatic washing machine, and thereby releases contained detergent composition to the wash water earlier in the washing process than do other "dissolvable packets" which are made of poly-vinyl alcohol.  When a soil release promoting agent (SRP), such as PET POET copolymer, is present in the particulate detergent composition superior soil release promotion is noted when washing polyester and polyester blend laundry, compared to washing such laundry with controls wherein the SRP is in a detergent composition that is not in a packet, or is in a composition in a PVA packet, without any CMC/ cellulose sheet material being present.

Abstract: A vaccine for immunizing animals, including human beings, against diseases caused by microorganisms producing an osteolytic toxin, the vaccine comprising an immunologically effective amount of a recombinant, immunogenic, detoxified Pasteurella multocida toxin or toxin analogue. The vaccine is encoded by a DNA fragment comprising a nucleotide sequence coding for a Pasteurella multocida toxin or toxin analogue, the nucleotide sequence being derived from a Pasteurella multocida genome, from a bacteriophage infectious for Pasteurella multocida, or from a plasmid or being a synthetic sequence which is inserted in an expression vector capable of replicating in a suitable host microorganism in which the said DNA fragment may be expressed in terms of production by the host microorganism of Pasteurella multocida toxin or toxin analogue when it is cultivated under suitable conditions, the produced toxin or toxin analogue optionally being subjected to posttransscriptional modifications to provide the detoxified toxin or toxin analogue. Alternatively, the nucleotide sequence coding for the toxin or toxin analogue may be modified prior to insertion into the expression vector so as to provide the expressed toxin or toxin analogue in a detoxified form. A monoclonal antibody has been raised against a Pasteurella multocida toxin which may be useful as a diagnostic agent for determining the presence of a Pasteurella multocida toxin or toxin analogue in a sample.       Further-more, the said monoclonal antibody may be useful for isolating a Pasteurella multocida toxin or toxin analogue from a biological material. A further scope for a useful diagnostic agent which is provided for is the application of a labelled DNA sequence homologous with a DNA sequence coding for a Pasteurella multocida toxin or toxin analogue for the detection of Pasterualla multocida toxin-producing microorganisms. The toxin or toxin analogue per se may be usefully applied for determining the presence of antibodies against a Pasteruealla multocida toxin or toxin analogue in a sample and may also be useful as a reference standard in analytical procedures aiming at quantitative or qualitative determination of the said toxin or toxin analogue in a biological sample or intermediate or final vaccine preparations.

Abstract: A boron carbide/titanium diboride composite ceramic powder is disclosed produced by mixing boron carbide and a titanium source, such that the average reactant particle size is less than 20 micrometers and substantially all discrete reactant areas are less than 50 micrometers, followed by heating the mixture wherein the boron carbide particles form substrates to which the titanium diboride particles are attached.  The resulting powder has boron carbide and titanium diboride particles less than 20 micrometers in diameter.  This powder can then be densified to form a part wherein the titanium diboride grains have an average size of less than 20 micrometers and the boron carbide grains having an average size of less than 50 micrometers.  Because of the uniformity of initial dispersion, the densified part shows a microstructure that is also very uniform in distribution of boron carbide and titanium diboride.

Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE A novel butterfly valve  is provided herein.   The butterfly  valve  is  of  the  type  having  a  spherical protuberance    formed on a valve stem connected to a valve body,  the  spherical  protuberance  being  supported  in a support member mounted in a casing, the valve body being engageable with,  and disengageable  from,  a valve  seat through pivotal movement and rotational movement of the valve stem about the spherical protuberance so that the valve body is rotatable when it is away from the valve seat.  The butterfly valve comprises a drive shaft disposed at a location adjacent to the outer end of the valve stem and extending outward therefrom,  the drive shaft being rotatable   in   forward   and   reverse   directions   and reciprocatable in  longitudinal directions of the valve stem.  One end of the drive shaft is connected to the outer end of the valve stem to enable the valve stem to rotate in cooperation with the reciprocating movement of the drive shaft in the longitudinal directions thereof.  A packing member is provided for shaft sealing with respect to the drive shaft, the packing member being disposed between the drive shaft and an outwardly-extending portion of the valve casing,  for covering the outer peripheries of the valve stem and of the drive shaft.  This structure assures more complete shaft sealing without causing any inconvenience to the controllability of the valve body and valve stem and can  thus  advantageously  prevent  fluid  from  leaking outwardly of a valve casing.
