Abstract: In a stripline filter (40) a stripline resonator (42) and a stripline resonator (44) are mutually coupled. In order to be able to influence the type of coupling (inductive, capacitive or a mixture thereof) the distance between the stripline resonators (40, 42) changes over the length of the stripline resonators (40, 42). If the stripline resonators are shorted at the end where the distance between them has a minimum value the coupling is substantially inductive. If the stripline resonators (40, 42) is open or capacitively loaded at the end where the distance has a minimum value, the coupling is substantially capacitive.

Abstract: In a tire (30) having a tread with cap/base (33/32)
construction, a regulated amount of partially crosslinked
natural rubber in a tire tread compound increases the
uncured ("green") stiffness, tensile strength and tear
resistance of a green compound used for the base (12)
without adversely affecting physical properties of the
tread after it is cured. Such green stiffness is
particularly useful in the construction of a tread for a
pneumatic tire, which tread is of cap/base construction
because stiffness provides requisite dimensional stability
of both cap and base (in the tread) during the curing of
the tire. The amount of partially crosslinked natural
rubber used in a tread compound depends upon the extent of
crosslinking in the natural rubber, the non-crosslinked
remainder being virgin latex.

Abstract: The flow of fluid through an annular bed (38) in a
radial flow treatment vessel (10) is improved by disposing
an elongate annular baffle (42) in the reactor adjacent the
bed to impart generally U-shaped flow to the fluid either
prior to entering or after it exits the bed thus achieving
an overall serpentine or reverse U-shaped flow pattern as
the fluid proceeds from an entry port (18) to an exit port
(20) in the reactor. Means can be provided in the baffle
(42) to permit minor amounts of fluid to by-pass the
generally U-shaped flow path in order to correct fluid flow
maldistribution through the bed attributed to frictional
pressure drop in the flow channels adjacent to the bed. A
vessel according to the invention can be operated with
fluid flow through the vessel in either direction.
