Title: Method of forming metal matrix composite bodies by a self-generated vacuum process, and products produced therefrom
Inventor: KANTNER ROBERT C
IPC: C04B35/65
Filed: 1990-07-06
Abstract: Abstract The present invention relates to a novel process for forming net or near net-shape metal matrix composite bodies.  Particularly, a molten matrix metal is in contact with a filler material or a preform in the presence of a reactive atmosphere, at least at some point during the process, which permits molten matrix metal to react, at least partially or substantially completely, with the reactive atmosphere, thereby causing molten matrix metal to infiltrate the filler material or preform due to, at least in part, the creation of a self-generated vacuum.  Such self-generated vacuum infiltration occurs without the application of any external pressure or vacuum.  The molten matrix metal infiltrates the filler material up to at least a portion of a provided barrier means.

Title: Spatial light modulator using electron trapping materials
Inventor: STORTI GEORGE M
IPC: G02F1/17
Filed: 1990-10-10
Abstract: ABSTRACT OF THE DISCLOSURE                      A novel, high-speed spatial light modulator utilizing electron trapping materials.  The electron trapping material is exposed to a pattern of modulating radiation, resulting in the excitation of electrons in the material at spatial locations corresponding to the pattern.  When the light to be modulated (ordinarily coherent light) is simultaneously or subsequently passed through the material, it is absorbed in areas of the material where electrons have been excited.  The unabsorbed modulated light passes through the electron trapping material, producing a negative image of the pattern of modulating radiation.  The electron trapping material also emits an image of incoherent visible light as the released electrons fall back to the ground state.  This visible image can be filtered out if the device is only being used for modulating coherent light.  Conversely, the device can be utilized by detecting only the incoherent visible emission from the electron trapping material, which constitutes a multi-plicative product image of the electron exciting and electron releasing light incident on the electron trapping material.

Title: Process and device for the mechanized suspension of sausages
Inventor: KOLLROSS GUENTER
IPC: A22C15/00
Filed: 1990-10-23
Abstract: Abstract A process for the mechanized suspension on smoking or cooking rods of individual sausages produced in an automatic filling installation with pear-shaped suspension loops fastened to their ends is characterized in that following the picking up by a first pair of conveyor elements from the discharge area of the filling pipe the pear-shaped suspension loops are raised up and are simultaneously flared, whereupon the flared pear-shaped suspension loops are picked up by a second pair of conveyor elements, are moved away over the smoking or cooking rod which is chucked at one end and finally are placed on the point provided for that purpose on the smoking or cooking rod.  Thus a sequential alignment of sausages of desired length is facilitated with standard size pear-shaped suspension loops on conventional smoking or cooking rods, and the sausages cut from the string of sausages are immediately lifted out of the area in front of the filling pipe opening to a higher level, so that the area in front of the filling pipe opening remains free and the pinching off or swaging and sealing tools as well as the casing brake ring can be removed unhindered for realignment and reuse of the filling pipe with tubular casing material.

Title: Amplification methods
Inventor: COPLEY CLIVE G
IPC: C12N15/09
Filed: 1991-01-24
Abstract: Abstract The invention provides a method for amplification of nucleotide sequences.  The nucleic acid fragment to be amplified comprises an unknown sequence, a first priming region of known nucleotide sequence for hybridisation with a first fragment and a vectorette portion at least one fragement of which has a nucleic acid sequence which in either its double stranded complementary form or its single stranded form is capable of being bound by protein.  The target nucleic acid fragment/vectorette unit is treated with appropriate nucleoside triphosphates and an agent for polymerisation of the nucleoside triphosphates under hybridising conditions.  Under these conditions an extension product of a first priming region is synthesised complementary to a single stranded target nucleic acid/vectorette unit having a first priming region to which is hybridised a first primer selected so as to be substantially complementary to the first priming region.          No such extension product is synthesised complementary to single stranded target nucleic acid fragment/vectorette units having no such first priming region.  The method is particularly useful for the amplification of sequences only a portion of which is known and enables long nucleotide sequences to be rapidly and efficiently sequenced.

Filed: 1991-04-24
Abstract: A communication network uses a network switch number (NSN) and a class-of-service classification (COS) code to route calls through the network. When a call is received at an originating switch of the network, the dialed number is used to select the NSN which identifies a network terminating switch which connects to the called party. The network uses received call signaling information and stored trunk information and possibly network database information to determine the COScode. The COS code is also used at the terminating switch to identify the type of service trunk to connect to the called party. In another feature, only the network switch number is used to route the call over the network. In accordance with yetanother feature, the COS code may be used to select specific network trunks without requiring the specification of the NSN.
