Title: Mechanism of sharing of guaranteed resources
Inventor: WEISS MICHAEL
IPC: G06Q10/06
Filed: 2000-07-05
Granted: 2003-09-16
Abstract: A method is set forth for service allocation among a plurality of entities i n a communications or computing environment based on a principle of guaranteed service rather than specific sale. Entities are provided with economic utili ty in amounts in proportion to their priority or importance by a dynamic ranking mechanism. Rather than allocating a "quantity" of utility to obtain resource s, the present invention uses utility to allocate the "possibility of failure due t o lack of resources". Thus, an entity purchases guarantees of service but these guarantees can be withdrawn if another entity is willing to pay more. Consequently the present invention makes any amount of resource available to an entity, up to a set resource maximum, if the entity has enough importance.

Abstract: A metallurgical lance for injecting solid particulate material into a smelting vessel including a central core tube through which to deliver the solids material and an annular cooling jacket surrounding the tube. The jacket includes a long hollow annular structure formed by outer and inner tubes interconnected by a front end connector. An elongate tubular structure is disposed within the annular structure to divide the interior thereof into an inner and outer annular water flow passages. The tubular structure has a forward end piece fitting within the front end connector to form an annular end flow passage which interconnects the forward ends of the inner and outer flow passages. The effective cross-sectional area for water flow through the annular end passage is less than the cross- sectional flow area of the inner and outer passages to produce a high water flow rate in the tip region of the cooling jacket.

Abstract: A container comprising an inner thermoformed vessel (11) and an outer thermoformed vessel (2), arranged the one within the other. The side walls (9) of the outer forming (2) surround the side walls (10) of the inner forming (1). The outer side walls has inwardly projecting ribs (11), which abut the inner side walls (10) to maintain an air gap (12) between the formings, with the formings being centred with respect to each other. The air gap is present between the bases (13, 14) of the inner and outer formings, with the outer forming being provided with ribs in its base also.

Abstract: A downhole valve that may be opened and closed by alternatingly pressurizing/bleeding a first control line, which is in fluid communication with a first surface of an activating member, and a second control line, which is in fluid communication with a second surface of the activating member. The fluid within the control lines is the same density as the fluid found in the annulus of the wellbore. The development of a leak in the control lines therefore does not by itself result in the actuation or movement of the activating member or valve member.
