IPC: E21B/
Filed: 1992-01-17
Abstract: The present invention is directed to shear ram blowout preventer apparatus for severing and sealing about borehole retrievables, particularly about flexible lines, multi-strand cables. The present invention provides an improved shear ram apparatus including keys (64) and cooperating retainer slots (60) for preventing relative longitudinal movement of the blade member (40) and anvil formation (80) carried on opposable ram assemblies (20, 70) when those assemblies are moved laterally inwardly to their shearing or closed position. In a preferred embodiment the shear ram apparatus of the present invention includes a plurality of keys (64) extending inwardly from the inward face of a first shear ram assembly (70) for cooperation with a plurality of slots (60) on the inward face of a second shear ram assembly (20) wherein the keys (64) engage the slots (60), thus preventing relatively longitudinal movement, particularly separation, before contact of the blade member (40) and anvil formation (80).

Title: Methods and compositions for modulating ethylene levels in plant tissues
Inventor: YANG SHANG F
IPC: C12N15/09
Filed: 1991-04-25
Abstract: Novel compositions and methods are provided for modifying the ethylene levels of plant tissues of interest, including petal, leaf and various fruit tissues. The methods involve transforming a plant cell of interest with an expression cassette functional in a plant cell comprising a transcriptional and translational initiation regulatory region, joined in reading frame 5' to a DNA  sequence encoding an enzyme capable of modulating the production of ethylene, and translational and transcriptional termination regions.  Expression of the enzyme provides for a decrease in ethylene production as a result of altered concentrations of substrate for enzyme involved in ethylene biosynthesis. Of particular interest is the selective control of ethylene production in plant tissues such as flowers, fruit and leaves, especially to inhibit dramatic increases in ethylene production related to fruit and tissue senescence, abscission and/or ripening.

IPC: C07J1/00
Filed: 1991-05-08
Abstract: ABSTRACT       The new intermediate products of general formula I       (I), in which R1 stands for a hydrogen atom or a straight-chain or branched alkyl group with 1 to 4 carbon atoms, R2 stands for a hydrogen atom or a methyl group, R3 stands for a hydrogen atom as well as R4 stands for an acyloxy group with l to 4 carbon atoms in the acyl radical or else R3 and R4 together stand for a keto-oxygen atom, are suitable in an excellent way for introducing a .DELTA.1 double bond in the steroid skeleton with the simultaneous presence of a .DELTA.4 double bond as well as saturated carbonyl groups by cleavage of hydrogen iodide with a base in an amidic solvent at elevated temperature.  If R2 stands for a hydrogen atom, the A-ring is aromatized after the hydrogen iodide cleavage.    For the production of new intermediate products, special iodization processes, which partially also allow a stereoselective control of the iodization, are used.

Title: Noble metal on rare earth modified silica alumina as hydrocarbon conversion catalyst
Inventor: SOLED STUART L
IPC: B01J23/10
Filed: 1993-01-29
Abstract: Rare earth oxides, such as Nd2O3 disperse onto the surface of SiOg/A12O3 and act as weakly basic titrants. This lowers the acidity of SiO2/A12O3 to close to that of chlorided alumina, as shown by model compound reaction tests. This support also disperses a noble metal such as Pt much better than undoped SiO2/Al2O3 and similar to chlorided alumina. Platinum on the rare earth modified silica alumina can function as a hydrocarbon conversion catalyst in reactions where Pt/chlorided Al2O3 is used, such as in reforming, and isomerization, especially wax isomerization.

Title: Passive keyless entry system
Inventor: WARAKSA THOMAS J
IPC: H04L7/04
Filed: 1993-04-21
Abstract: ABSTRACT OF THE DISCLOSURE     A  passive  keyless  entry  system  is  disclosed  that  is specifically adapted for use with automotive vehicles.   The system includes a portable beacon that is carried by a vehicle operator, a receiver/controller located in the vehicle, and an antenna connected to the receiver/controller for receiving an encoded transmission from the beacon.  The system is designed to automatically unlock the vehicle as the operator approaches the vehicle.  The system is further designed to automatically lock the vehicle as the operator, carrying the beacon, moves away from the vehicle.  The beacon includes a motion sensor to conserve battery life when the beacon is stationary. Transmission between the beacon and the receiver/controller is characterized by a magnetically   coupled   radio   frequency   signal   embodying differential phase encoded data with error correction coding of the data to enhance noise immunity and signal discrimination.          In addition, the transmitted signal between the beacon and the receiver is continually changing in order to deter theft.   A clock in the receiver/controller is automatically reset to a clock code of the encoded transmission if the transmitted signal is valid.

Title: Skin-associated lymphocytes and markers
Inventor: BUTCHER EUGENE C
IPC: C07K14/705
Filed: 1991-11-14
Abstract: Regulation of hematopoietic cell association with skin during chronic inflammation may be modulated by the use of agents which selectively identify and target skin associated leukocytes or inhibit the binding of a skin associated antigen (CLAM-1) with receptors present in cutaneous associated cells. The agents may be used for diagnosis of inflammations and malignancies associated with the presence of the CLAM-1 carrying hematopoietic cells at cutaneous sites. By employing lymphocytes or other antibodies or cytotoxic agents, inflammatory disorders mediated by cutaneous lymphocytes or other T-cells or skin associated T-cell malignancies may be treated. Cutaneous inflammation and lymphoid neoplasia can be characterized and modified by the agents which selectively identify and target skin-associated T-cells or which inhibit the binding of CLAM-1 with receptor(s) present in cutaneous associated cells.
