Patent EP-0350294-A2 (EP)
Inventor: TAKEMURA YASUHIKO
IPC: C30B15/00
Filed: 1989-07-05
Abstract: Superconducting oxide ceramics, particularly those that are based upon Bismuth (Bi), can be different to form in the requisite structure and the invention proposes a method according to which a ceramic which is easier to make and has a similar molecular structure is used as a starting material to initiate and/or encourage the development of the superconducting ceramic material as desired. For example, superconducting ceramics may be produced in crystalline form by use of a crystal pulling technique in which a seed crystal is easily prepared from another ceramic material which is non-superconducting but has a similar molecular structure to that of the required superconducting ceramic. By virtue of the similarity in the crystalline structure, single crystals of superconducting ceramic materials can easily be produced. Similarly, superconducting ceramic material can be formed upon a substrate of a non-superconducting ceramic material having a similar molecular structure.

IPC: B67D1/00

Abstract: A container (10) for pressurised fluid, e.g. carbon dioxide, is fitted with a self-sealing valve (11) comprising a valve body (12), a valve stem (13) mounted in the valve body for axial movement relative thereto, and a valve member (14) connected to the inner end of the valve stem. A first 'O' ring seal (21) creates a seal between the valve stem and the valve body and a second 'O' ring seal (25) creates a seal between the valve member and the valve body under the urging force of pressurised fluid in the container. The valve stem has an axially extending discharge passage (19) which communicates with the outside of the valve stem at a position intermediate the seals (21 and 25) and a valve operating member (33) is threadably connected to the valve body so that when it is turned in an appropriate direction the operating member engages with an abutment (37) on the valve stem to move the valve stem and valve member against the urging force of the pressurised fluid to break the seal between the valve member and the valve body and so allow fluid within the container to pass through the discharge passage in the valve stem. The valve member is equipped with a pressure relief valve which includes a burstable metal disc (29).

Abstract: A method is disclosed for treating papermill felts and the like to inhibit the deposit of sticky material thereon. The method comprises (a) applying an aqueous solution which contains at least about 2 ppm of a cationic polymer; and (b) applying an aqueous solution which contains at least one compound selected from the group consisting of water soluble nonionic and cationic surfactants; the surfactant being applied in an amount effective to inhibit build-up of deposits derived from the cationic polymer. Cationic surfactants are preferred. Particular use is disclosed of water soluble surfactants which have a molecular weight between about 200 and 800 and having the general formula:
      wherein each R is independently selected from the group consisting of hydrogen, polyethylene oxide groups, polypropylene oxide groups, alkyl groups having between about 1 and 22 carbon atoms, aryl groups, and aralkyl groups, at least one of said R groups being an alkyl group having at least about 8 carbon atoms, and wherein X⁻ is an anion, or 1/n of an n-valent anion. Compositions comprising said cationic polymers and said surfactants in a weight ratio of surfactant to cationic polymer of from about 50:1 to about 1:1 are disclosed as particularly useful.

Abstract: An orthogonal transform apparatus wherein in N-th order DCT or DST, the multiplier used for weighting N orthogonal coefficients Yi (i=0, ..., N-1) is one of, a combination of two or more of, or a multiple of one of, the following four sets: 
· COS (i/2N) 
· SIN (i/2N) 
· 1/COS (i/2N) 
· 1/SIN (i/2N) 
to thereby considerably reduce the number of multipli­cations in both orthogonal and inverse orthogonal trans­form as compared with the conventional. Since the number of multiplications required for calculating one orthogonal coefficient can be reduced, it is possible to reduce operation errors to be caused by multiplications. Further, it is possible to improve the operation preci­sion of an orthogonal coefficient for lower frequency components which have an important role from the stand­point of visual sense. Finally, by applying the ortho­gonal transform apparatus to two dimensional orthogonal transform and two dimensionally weighting after obtain­ing two dimensional orthogonal coefficients, it becomes possible to reduce the number of multiplications while performing a desired two dimensional weighting.

Abstract: A computer program specification system is disclosed for interactively creating program specifications responsive to user input. The system provides facilities to respond to changes, supplied interactively, to a program specification without recompiling the program specification, and immediately to display a simulation of those changes. The system also supports the merging of actors, which are software objects comprising data structures and program procedures, and the merging of actor behavior. A user of the system creates a program specification by specifying actors for use in a plurality of scenarios, and operational steps of the plurality of scenarios. The system executes operational steps of a scenario to evaluate the consistency of the specification and actor data. Execution of an operational step comprises simulating the operational step upon the occurrence of predetermined conditions and storing the results of the simulation. Execution of a sequence of operational steps can be reversed or undone in order to insert a change in the specification prior to resimulating the undone sequence or other related sequences. Simulation of an operational step comprises one or more of: executing communications among actors, asserting relationships among actors, executing a logical or arithmetical computation for actors or requesting input of a decision choice.
