Abstract: The invention relates to a roof and roof assembly for a motor vehicle. The invention also relates to methods of making the same. The roof assembly comprises of a roof structure formed from a sheet of metal material and defining a roof opening. An opening roof assembly is mounted to the roof structure and movable between opened and closed positions with respect to the roof opening. A single piece of sheet metal is stamped to integrally form a water-catching channel and roof reinforcement portions. The sheet metal is fixed to the roof structure adjacent to the opening so that the channel extends into the opening to enable the channel to catch water running off the roof structure into the opening when the opening roof assembly is in the opened position. Conduits communicate with the water-catching channel for draining water from the water-catching channel.

Inventor: PAASONEN JAN A
IPC: D21G1/02
Filed: 1997-04-03
Abstract: The problems caused by chemical and thermal shrinkage of hard roll covers, are reduced by the inclusion of one or more intermediate compressive layers between a roll core base and cover. The compressive layer has the properties of being rigid enough to allow the cover to be applied to the roll, and compressible enough to deform and absorb the stresses which occur as the cover is shrinking during processing. In one embodiment, the compressive layer is separately cast with the cover over a disposable inner mold so as to form a composite roll cover. The composite roll cover is fitted over a roll core base and the resulting circumferential cavity is then filled with a thermoset resin.

Title: Hot runner coinjection manifold back arrangement
Inventor: FERNANDEZ LUIS
IPC: B29C45/27
Filed: 1997-06-12
Abstract: The hot runner coinjection manifold block arrangement comprises several block parts (6, 7) which may be raised to various temperatures using heating elements (8). These block parts (6, 7) are separated by an adaptor (9) and retained against the top plate (2) by a supporting element (10). The latter (10) incorporates elastic elements, preferably disc springs (11), that separate the supporting element (10) from the top plate (2) and press together the two block parts (6, 7) even in a cold state. In heated state these disc springs (11) enable axial expansion of the block parts (6, 7) and reduce the stress exerted on the supporting element (10). Pin-type formations on the adaptor (9) and the supporting element (10) ensure that the bores for controlling the locking needle (17) and the conveyor channel (13) are maintained by the thermal expansion of the block part (6, 7), i.e. are not laterally displaced.

IPC: A01K1/01
Filed: 1999-09-28
Abstract: A circular cat litter container where a sieving mechanism is attached to a rotatable ring atop the container. The circular motion of the ring moves the sieve throughout the entire contents of the litter container capturing any solid waste that is too large to pass through the sieve. The sieve mechanism has axis of movement such that the sieve can be folded out of the way of the contents of the container when the sieve is not in use. The container and sieving mechanism are designed such that the sieve automatically moves into a scooping position when the ring is rotated in a clockwise motion. Conversely, when the ring and sieve are rotated counterclockwise, the sieve automatically is placed in an "out of the way" or resting position. The sieving mechanism is removably attached to the rotatable ring such that the sieve serves to act as a litter scoop to remove and discard the solid waste material found in the litter container. If desired the litter container can be made oval or rectangular with rounded corners and the ring can be replaced by a carriage moving along a track on the container sidewall and supporting the sieving mechanism. Also if desired, the container sidewall can be made non-continuous and the litter can be discharged through a gap into an auxiliary container at each end of its movement.

Abstract: A broadcast or multicast message from a network station is forwarded only to stations in the same virtual broadcast domain (VBD) as the sending station. In some embodiments, a VBD is virtual network (VLAN) or a workgroup (a group of stations, possibly within a VLAN). A membership of a network station in a VBD  is determined based on the user who logged on to the station. When the station is first powered up, it is bound to a "default" VBD. When a user logs on, the VBDs assigned to the user are determined, and the user's station is switched to the VBDs. When the user logs off, the user's station is returned to the default VBD.

Inventor: DORLING ANTHONY
IPC: H04W4/00
Filed: 1998-03-26
Abstract: The invention relates to the inhibition of blood coagulation, especially during organ rejection, and in particular the inhibition of delayed vascular rejection. The invention provides anticoagulant proteins which are anchored to cell membranes. The anticoagulant function is preferably provided by heparin, antithrombin, hirudin, TFPI, tick anticoagulant peptide, or a snake venom factor. These anticoagulant proteins are preferably prevented from being constitutively expressed at the cell surface. In particular, expression at the cell surface is regulated according to cell activation, for instance by targeting the protein to a suitable secretory granule. Expression of these proteins renders cells, tissues and organs less vulnerable to rejection after transplantation (e.g. after xenotransplantation).
