Abstract: A process for the manufacture, in an injection moulding process, of articles having barrier properties, is disclosed. The process comprises feeding an admixture of 20-87.5 percent of polyethylene and/or ethylene/vinyl acetate copolymer, 5-40 percent of at least one of polyamide, ethylene/vinyl alcohol copolymer, polyvinyl alcohol and polyester, and 7.5-40 percent of an alkylcarboxyl-substituted polyolefin to injection moulding apparatus, heating the admixture to a temperature above the melting point of all components of the admixture under conditions that minimize admixing of the admixture and then injecting the resultant heterogeneous molten mixture into a mould. The process may be used to manufacture articles e.g. containers, intended for use with foodstuffs and the like that have improved barrier properties with respect to a number of substances e.g. oxygen.

Abstract: A circuit breaker device has a chamber in which is disposed a single break contact system using low contact resistance material mounted on movable and stationary supports arranged in a loop configuration in order to direct arcs between the contacts through an arc chute into a remote portion of the chamber. A push-button is connected through a kinematic linkage which transfers motion using minimal frictional engagement to a movable contact to bring the movable contact into and out of engagement with a stationary contact and to latch the contacts in engagement during normal operation. A cantilevered current carrying bimetal transfers motion caused by I R heating of the bimetal to an ambient compensating bimetal connected to the latch mechanism. The kinematic linkage includes a latch surface which engages a rollable cylindrical reaction surface of the latch mechanism to cause the movable contact to come into engagement with the stationary contact upon depression of the push-button. Upon overload, the latch mechanism is displaced with the latch surface moving away from the reaction surface allowing return springs to return the push-button to its unactuated position and separate the contacts.

Abstract: A cavity resonator (10) suitable for use in a high-speed nu­clear magnetic resonance (NMR) imaging device comprises a plurality of transmission lines (18, 19, 20) aligned parallel to a common axis (21) and magnetically coupled to produce an essentially uniform dipole mag­netic field (28) perpendicular to the axis (21). The transmission lines (18, 19, 20) are two conductor lines, with the first conductors being arranged inwardly of a second conductor (12) common to all lines. The common conductor (12) is symmetrically arranged about the axis (21) of the resonator (10) and constitutes a shield to contain the magnetic field (28) within the cavity. The plurality of transmis­sion lines (18, 19, 20) are connectively isolated from each other but spaced in sufficiently close proximity to each to provide for strong mutual magnetic coupling amongst all transmission lines. A single in­ductive coupling loop may be provided for driving the resonator (10) with a linearly polarized magnetic field (28) and for receiving NMR information from the resonator. The use of a pair of inductive cou­pling loops (35, 37) spaced 90° about the resonator axis (21) provides a circularly polarized magnetic field (28) within the resonator (10) when the loops are driven in electrical phase quadrature. Two induc­tive coupling loops (31, 33) (35, 37) for each imaging mode may be provided to eliminate undesirable modes and hence distortion in the NMR image. The common conductor (12) and the longitudinal ends of the resonator (10) are provided with slits (15) designed to allow the changing high-speed gradient magnetic fields (28) to fill the imaging volume fast enough to accomplish high-speed imaging.

Abstract: This invention enables easily and fast selection of candidates for an input character image among the character categories by search of a tree-structured dictionary. Each ordinary mode of the tree structure has three branches, that is, two ordinary modes and one reject node, and compares the multivalued feature extracted from the input character image for the node concerned, with a threshold, upper limit and lower limit values. If the feature value is out of the limited range, the search goes down to the reject node at the next level. If not, the search goes down to the right or left node at the next level based on the comparison of the feature value with the threshold value. Reject nodes have no branch. The tree structure has character category infor­mations as leaves connected to the bottom ordinary nodes and another character category information for all the reject nodes. Search of the dictionary gives one of the character category informations indicating the candidates, which are thereafter tested by detailed matching for outputting recognition result. In particular, this invention can use white pel run length as multivalued features. The white pel run length is defined as the run length of white pels from a point on an edge of the segmentation window to the nearest black pel or edge in a direction. It is easy to construct and optimise the dictionary, since many varieties of white run length are generated from a little sampling data.

Abstract: Es wird eine Addierzelle vorgestellt, bei welcher der Summen- und Carry-Signal gleich schnell gebildet werden. Eine solche Addierzelle ist für den Einsatz in "Carry-Save"-Addierern vorgesehen, bei denen das Summen- und das Carry-Signal getrennt zu beliebigen Eingängen zu nachfolgenden Addierern weitergegeben wird. Die Schaltung der Addierzelle ist so ausgelegt, daß das Summen- wie auch das Carry-Signal jeweils nur zwei Gatter durchlaufen müssen. Simulation mit realisierten Zellen bestätigen, daß die Laufzeiten von Summe und Carry-Signal annähernd gleich und kleiner sind als die maximale sich aus dem Summensignal ergebende Laufzeit von konventionellen Addierzellen.

Abstract: In a peniotron, hollow electron beam (e) is gener­ated from a cathode gun assembly (11) and a DC magnetic field is applied to the electron beam (e) from solenoid coils (18, 19, 20). Thus, each electron of the electron beam (e) is gyrated into a resonant cavity and propagat­ing waveguide sections (13, 14) which are maintained in a auto-resonant conditions so that the electrons inter­act with an electromagnetic waves of TE mode not only in the resonant cavity section(13) but also in a waveguide section (14). Accordingly, the electromagnetic wave is oscillated in the resonant waveguide section (13) and amplified in the propagating waveguide section (14) such a manner that the level of the electromagnetic wave in the resonant cavity section (13) is far less than that output power from said propagating waveguide (14).

Abstract: An acoustic apparatus adapted to be heard only by a specific person or persons in one space without being worn by the user as in the case of an earphone. Sound signals emanating from the apparatus do not leak to the outside and are not affected by the surrounding moise. Basically, the apparatus is arranged such that a sound source (13) is disposed in one focus of a reflector (11, 35) having an ellipsoidal surface of revolution, and sound signals are heard at the other focus. To increase the number of specific hearers, if the central portion of the reflector (35) is made into a non-ellipsoidal surface of revolution, or a cross section having an ellipsoidal surface of revolution (45) is extended orthogonally to the cross section by a predetermined length, the range of the other focus expands. In addition, by arranging a plurality of reflectors (51A, 51B), it is possible to hear different sound signals within the effective areas of the respective reflectors (51A, 51B) without mutual interference of the sounds.
