Title: System and method for two sided sheet treating
Inventor: WILLIAMS JOEL LANE
IPC: D21H23/56
Filed: 2000-02-28
Granted: 2001-11-15
Abstract: A system and a method for coating two sides of a laminate material is disclosed in which one side of the laminate material is coated with one substance and the second side is coated with a similar or different substance. Reverse roll coating may be used to coat the two surfaces of the sheet of laminate material. The method described is particularly suited for applying a substance providing balancing characteristics desirable in the end product to one side of the laminate material and applying a substance providing other characteristics desirable in the end product to the other side of the laminate material. For example, a balancing substance may be applied on one side of a kraft paper sheet and a substance providing structural bonding applied to the other side, thereby eliminating the need to use a discrete balancing sheet in a laminate. The kraft sheet thus coated may be used to form a laminate panel that may be applied on an exterior wall, an interior wall, siding, a roof top, a facade boarding, a counter top, a table top or a work top. <IMAGE>

Title: Communications cable having microbial resistant water blocking provisions
Inventor: ARROYO CANDIDO JOHN
IPC: H01B11/00
Filed: 1991-01-15
Granted: 1996-12-17
Abstract: A communications cable includes water blocking provisions which are microbial resistant. The water blocking provisions include a microbial resistantwater blocking member comprising a laminate which includes two tapes with a superabsorbent powder therebetween. Advantageously, the superabsorbent powder on contact with moisture swells to block further intrusion of moisture and to prevent its movement longitudinally within the cable. The tapes of the laminate may be non-cellulosic such as for example a spunbonded polyester material which has suitable tensile strength and which has a relatively high porosity and further which prevents the growth of fungus. An adhesive system included in the laminateis sufficient to hold together the tapes and the powder without inhibiting swelling of the powder on contact with water.

Title: Valve assembly, for use in combination with a straight-cylinder, gas-compression chamber, and in combination therewith
Inventor: BENNITT ROBERT A
IPC: F04B53/10
Filed: 1991-02-04
Granted: 2001-06-12
Abstract: The Assembly, designed for use in combination with a straight-cylinder, gas-compression chamber, has a center bolt which is threaded at opposite end thereof to receive a pair of valve sets. Each of the latter has a ported valve seat, valve guard, and valve plate.      The guard is set about the bolt, and against a shoulder formed on the bolt therefor. The seat is centrally threaded, to engage one of the threaded ends of the bolt, and it and the guard confine the valve plate therebetween. In that one of the valve sets is turned 180° from the other, i.e., the two guards being in confrontation, and the two seats remotely disposed, the one valve set is open to fluid flow, while the other is closed, as the Assembly is reciprocated in such a straight-cylinder, chamber. Identical valve sets, on different, short bolts set in end closures of such a chamber, serve as gas inlet valves, while the reciprocable Assembly carries the discharge valves. The invention obviates any need for pistons, per se as, according to a feature of the invention, the valve sets carry replaceable sealing (viz., piston rings).

Title: Optical unit actuator for information recording/reproducing apparatus
Inventor: GOTO SHOJI
IPC: G11B7/085
Filed: 1991-02-12
Granted: 1996-01-09
Abstract: An  optical  unit  actuator  for  an  optical information  recording/reproducing  apparatus  includes  an electromagnetic drive mechanism composed of a coil and a magnet cooperative to drive an objective lens mounted on an optical unit.  One of the coil and the magnet is secured to the optical unit.  The other of the coil and the magnet is held on a fixed unit with an elastic support member disposed therebetween, the fixed unit being immovable as against the movable  optical  unit.     The  elastic  support  member substantially dampens or takes up vibration caused by a reaction force caused as a result of acceleration of the objective lens when the objective lens is driven to follow a dynamic radial  runout and an axial deflection of an optical  disk.    With  the  elastic  support  member  thus provided, an optical component, a photoelectric transducer or the optical disk which is disposed on the side of the fixed  unit  is isolated  from  vibration.    The  control characteristics of a system including an optical head, the optical disk and a control circuit for the optical head can, therefore, be improved.
