Title: Powder metallurgical compositions and parts made therefrom
Inventor: SCHADE CHRISTOPHER T
IPC: C22C32/00
Filed: 2005-06-09
Granted: 2011-10-04
Abstract: Metallurgical powder compositions are provided that include calcium aluminate additives, i.e., calcium aluminate or calcium aluminate containing powders, to enhance the machinability and durability of compacted and sintered parts made therefrom. The compositions generally contain a metal-based powder, such as for example, an iron-based or nickel-based powder, that constitutes the major portion of the composition. Calcium aluminate additives are combined with the metal based powder by, for example, admixing or bonding. Optionally, common alloying powders, lubricants, binding agents, and other powder metallurgy additives can be combined with the metallurgical powder composition. The metallurgical powder composition is used by compacting it in a die cavity to produce a "green" compact that may then be sintered, preferably at relatively high temperatures.

Title: Catalytic reactor
Inventor: BOWE MICHAEL JOSEPH
IPC: C01B3/38
Filed: 2006-01-11
Granted: 2014-08-19
Abstract: A compact catalytic reactor for Fischer-Tropsch synthesis (50) comprises a reactor module (70) defining a multiplicity of first and second flow channels arranged alternately, for carrying a gas mixture, and a coolant respectively.  A removable gas-permeable catalyst structure (82) with a substrate for example of metal foil is provided in each flow channel in which the synthesis reaction is to occur. The reactor module (70) is enclosed within a pressure vessel (90), the pressure within the pressure vessel being arranged to be at a pressure substantially that of the high pressure reacting gas mixture.  Consequently all the flow channels within the module are either at the pressure of their surroundings, or are under compression; no parts are under tension. This simplifies the design of the module, and increases the proportion of reactor volume which can be occupied by the catalyst.

Abstract: To communicate requirements for a digital license from a receiver of corresponding digital content to a computing device upon which the digital content is to be rendered, the receiver tunes the content and locates within the content information relating to the requirements for the license, constructs the requirements from the located information, and sends such constructed requirements to the computing device. The computing device upon receiving the sent requirements constructs the license based on such received requirements, stores such constructed license in a license store of such computing device, and thereafter renders the content only in accordance with the license. Thus, the receiver need not communicate the license itself to the computing device.

Title: Apparatus for inspecting underwater structures
Inventor: BUCK BELA HIERONYMUS
IPC: G01N1/04
Filed: 2006-04-15
Granted: 2011-03-15
Abstract: Such inspection devices are used for observing and servicing aqua cultures, harbor systems or other surfaces submerged in water. They are provided with a smoothly adjustable vertical guidance with a telescoping rod and a smoothly adjustable horizontal guidance with a guide track setting a path and a carriage moveable thereon on guide rolls for receiving the vertical guidance and appropriate inspection devices. Hitherto this required specially trained divers, hoisting the subject to be inspected out of the water or using inspection devices of very limited action space. The invention proposed a cost-efficient inspection apparatus (IE) usable without divers and operable in a substantially unlimited observation space. For the vertical guidance (VF) the telescoping rod (TS) may be extended without forming bulges, and for the horizontal guidance (HF) the guide track (FB) may be set in changeable continuous curve or composed of linear sections. Vertical and horizontal guidance (VF,HF) define the inspection plane in the three dimensions for the diverse inspection devices (IG).

Title: Corner or edge protector exhibiting improved flexural strength and resistance properties
Inventor: KRUELLE JOHN
IPC: B65D81/05
Filed: 2006-04-10
Granted: 2010-12-21
Abstract: A new and improved external corner protector is fabricated from predetermined materials and comprises a vertex portion (112), and a pair of leg members (114, 116) which diverge outwardly at a predetermined included angle with respect to each other from the vertex portion. The vertex portion and distal end portions of the leg members have relatively enlarged cross-sectional dimensions relative to the cross-sectional dimensions comprising those portions of the leg members which integrally interconnect the distal end portions of the leg members to the vertex portion, wherein the relatively enlarged cross-sectional dimensions serve to reinforce the vertex portion and to dispose only such relatively enlarged distal end portions of the leg members into contact with the external side wall members of the palletized load which define the external corner region being protected. In this manner, the leg members of the external corner protector are flexed more than has conventionally been the case such that forces are generated and transmitted to the vertex portion so as to rigidify the same whereby the vertex portion will exhibit enhanced flexural strength and bending resistance properties with respect to external forces which may be impressed upon the external corner protector thereby tending to flex or bend the same.

Title: Process of making an alpha-anomer enriched 2-deoxy-2,2-diflouro-d-ribofuranosyl sulfonate and use thereof for making a beta nucleoside
Inventor: SCHLOEMER GEORGE
IPC: C07H19/173

Granted: 2011-08-30
Abstract: A process of preparing an alpha-anomer enriched 2-deoxy-2,2-difluoro-D-ribofunanosyl sulfonate of formula (I) (see formula I) wherein each Y is independently selected from hydroxyl protecting groups, and R is an alkyl, substituted alkyl, aryl, or a substituted aryl group. The sulfonate of formula (I) is useful as an intermediate in the preparation of a beta nucleoside, such as gemcitabine, an anti-tumor agent. A  beta-2-deoxy-2,2-difluoro-D-ribofunanosyl sulfonate is heated and converted to an alpha-2-deoxy-2,2-difluoro-D-ribofunanosyl sulfonate in the absence of an effective amount of a sulfonate salt to facilitate the conversion. In addition, an anomeric mixture of an alpha-anomer and a beta-anomer of 2-deoxy-2,2-difluoro-D-ribofunanosyl sulfonate can be dissolved in a mixture of water and a solvent and heated to produce a lactol, which may be further converted to an alpha-anomer enriched 2--deoxy-2,2-difluoro-D-ribofunanosyl sulfonate.
