IPC: H01H33/18
Filed: 1983-03-29
Abstract: An electric switch has an arc interrupter 16 mounted in a housing 12 between two main conductors 14. The interrupter comprises a fixed contact 20 having a first arcing surface 44, a fixed electrode 60 having a second arcing surface 62, an arc-driving coil 64 and a movable contact 82, the surfaces 44, 62 and the coil 64 being coaxial with one another and the contact 82 being mounted for angular movement about a pivot axis 86 between a make position and a break position. During opening of the interrupter, an arc is initially struck between the contacts 20, 82 after which it is transferred from the contact 82 to the electrode 60. The coil 64, now being part of the arc current path, produces a magnetic flux which interacts with the arc so that it is driven around the axis 18 between the surfaces 44, 62. That movement of the arc assists in extinguishing the arc at an appropriate current zero. Ferromagnetic material 54, 56, 58 forms part of the magnetic circuit of the coil 64. Two interrupters can be arranged in series between the main conductors. Alternatively, the interrupter can have two fixed contacts, two movable contacts and two coils. <IMAGE>

Title: Unwinding a roll of blocking- prone web
Inventor: REITER GODFREY
IPC: B65H19/10
Filed: 1983-09-13
Abstract: Web is unwound from a roll (23) via an idler roller (30), driven stripper roller (31) and drums (82, 83). The web which is prone to sticking or 'blocking' to the underlying web layers on the roll (23) is thereby peeled off the roll and the strain induced in the web as it leaves the roll is vitiated before it passes the forwarding drums (82, 83). The rollers (30, 31) are mounted on biassed pivoted arm (60) so as to keep idler roller (30) in contact with the roll (23). A nip roller may cooperate with stripper roller (31). The rollers and the web roll drive belt (54) are driven at controlled speeds to impart high strain to the web as it separates from the roll (23). The web may comprise a thermoplastic elastomer or a tyre ply and the arrangement avoids the use of anti- blocking powder or liner web between the wound layers of roll (23). <IMAGE>

Title: Simplified pre-processor for a constrained adaptive array
Inventor: WARD CHRISTOPHER ROBERT
IPC: G06Q10/00
Filed: 1985-10-25
Abstract: An adaptive combiner (1) is preceded by a data pre-processor (2) which acts to impose a linear weight constraint on the adaptive process. The pre-processor subjects the input data to a transformation described by a matrix A which satisfies the condition A S = C,where W<T>S = ??? defines the overall constraint and @<T>C = ??? defines the constraint on the adaptive combiner. The one or more look direction constraints can be applied by means of a simple form of array feed network. S is the "look direction" vector, C being a vector having only one non-zero component, of valve unity, e.g. the last. ??? is the gain constant, the components of vector W being weighting factors. <IMAGE>
