IPC: G08B21/16
Filed: 1978-10-10
Abstract: An apparatus and method for detecting liquids, vapors 
and gases, which includes a conventional detection device 
(10) operated in a non-linear region or current saturated condition 
so that it becomes sensitive even to substances having 
a Van der Waals' constant "a" of nine or less. A change in the 
level of either the current from battery (26) through the 
detection device (10) or the voltage across the detection 
device (10) occurs upon exposure of the device (10) to the 
substance being sensed. This current or voltage change is 
then detected by indicating means (28) to indicate the presence 
of the sensed substance. The relatively small current or 
voltage change associated with the detection device (10) 
may be easily sensed by placing the detection device (10) in a 
balanced bridge circuit. Further, the bridge circuit enables 
easy, accurate normalization of the apparatus in a reference 
environment. The non-linear characteristics of the detecting 
device (10) allow it to be employed as a regulator for supplying 
a constant current to a power consuming device.

IPC: B29C55/00
Filed: 1979-03-07
Abstract: A method and apparatus for continuously extruding, biaxially orienting 
and intermittently forming molded products from a web of thermoplastic 
material and further continuously separating the products from the web 
selvage, stacking and handling the products and recycling the web 
selvage for further extrusion. The method and apparatus use intermittent 
molding devices into which configuration the biaxially oriented web is 
interfaced by a continuous-to-intermittent interfacing structure which 
preserves the dimensional and orientational integrity of the web and 
maintains thermal stability therein. An undulating peripheral surface 
on a dynamic storage or accumulator drum and associated transfer rollers 
cooperate with intermittently advanced feed belts in timed relationship 
with a reciprocating forming press to effectuate the interface and 
product forming portions of the process. In some of the preferred 
embodiments the inertia at the interface between the undulating 
peripheral surface of accumulator drum and biaxial orientation apparatus 
is reduced to an optimal minimum.

Title: Jacket for magnetic disk memory
IPC: G11B23/033
Filed: 1983-05-04
Abstract: The invention provides an improvement in the structure 
of a jacket for a floppy disk-type magnetic disk memory. 
Different from conventional ones of bag-like form fabricated 
by two-fold folding of a plastic sheet followed by further 
folding of the peripheries and integral welding of the two 
leaves on the plane of the jacket, the inventive jacket 
comprises two separately shaped square covering sheet 
members each having the peripheries bent at right angle to 
form riser walls and engaged each with the other at the riser 
walls into a thin box-like form with the aid of inwardly raised 
projections at the corners of the covering sheet member 
serving as a spacer means so that the dimensional inaccura­
cy unavoidable in the folding work can be obviated. Further, 
the liners, which conventionally are integrally bonded by 
welding to the inside surface of the respective covering 
sheet, are provided separately from the covering sheet 
members so that the covering sheet members are free from 
thermal stress or distortion. A further improvement is 
obtained by providing the liner sheet with a peroipheral 
protrusion by which the liner sheet is manually or mechanic­
ally rotatable to provide a shutter means to the oblong side 
opening for recording and readout with a magnetic head.

Patent EP-0123492-A3 (EP)
Title: Centrifugal separator and method of operating same
IPC: B04B5/12
Filed: 1984-04-16
Abstract: A continuous flow device is disclosed for separation of particles of differing densities in a centrifugal force field. Very small particles of differing densities that are normally very difficult or impossible to separate in the usual commercial gravity separation devices can be separated because of the increased settling force due to the centrifugal force field and also the buoyant force on the particles of lesser density caused by a thickened slurry layer. A thin film of a slurry of solid particles of differing size and density travels over a revolving surface (20) of such configuration that the slurry flows in a substantially laminar manner. As the thin film of slurry flows along the surface, the particles of greater density tend to concentrate in the region next to the surface (20), while the particles of lesser density remain in or are forced into the fraction of the film closestto the axis of revolution (14). Before the film of slurry reachs the end (24) of the flow path it is passed over a splitting device (21) to separate the fraction of the film containing particles of greater density from the fraction containing particles of lesser density.

Patent EP-0136096-A3 (EP)
IPC: B29C65/48
Filed: 1984-08-29
Abstract: A technique for making a honeycomb structure includes 
bonding a less than totally cured composite skin (16) to a 
possibly contoured honeycomb core (8). The composite skin 
(16) comprises fibers and a resin chosen to maximize the 
strength and stiffness of the skin (16) when cured. Non-­
contiguous adhesive fillets (5) are prepositioned onto faying 
surfaces of the honeycomb core (8). The adhesive (5) is pre­
selected, independently of the preselection of the resin, to 
maximize the strength of the bond between the skin (16) and 
the core (8).  
     A thin, lightweight scrim cloth (14) is interposed between 
the starting skin (16) and the filleted core (8). The scrim cloth 
(14) prevents resin from flowing into the core (8) and allows a 
safe place for the intermingling of resin and adhesive (5). The 
assemblage is heated under pressure, cocuring the adhesive 
(5) and the resin. The fillets (5) are preferably prepositioned 
on surfaces (10) by means of applying an adhesive-coated 
fabric to the faying surface, heating the fabric-covered core 
(8) so that some of the adhesive (5) flows out of the fabric (1) 
and into the core (8) at a region near the flying surface, cooling 
the core (8) so that the only substance remaining adhered to 
the core edges (10) is the adhesive fillets (5).

Abstract: Paper or paperboard (10) which has been thoroughly 
dried, but not calendered is provided with a smooth surface by 
rewetting a thin layer along one surface thereof and then 
pressing the resulting damp surface against a substantial por­
tion of the surface of a heated smooth-surfaced drying cylinder 
(20). This technique provides the web (10) with a surface com­
parable in smoothness with that which can be obtained by cal­
endaring, but without the degree of compaction which occurs 
in calendaring, due to the fact that with the major portion of the 
web dried, it is highly resistant to such compaction.

Title: Positive displacement diaphragm pump employing displacer valves
IPC: F04B43/073
Filed: 1984-12-14
Abstract: A positive displacement pump (310) utilizes at leastthree driven displacer valves (360,362,364) and a plurality of driving membranes (336,340,344) and at least one pumping membrane (316) to withdraw minute quantities of corrosive fluid from a drum (100) and discharge same to a delivery point (128). The pump (310) is submerged within the fluid to be pumped and is driven by a remotely positioned pneumatic pulse generator (116) comprising pneumatic logic circuitry. The driven displacer valves (360,362,364) operate in a particular sequence to draw fluid into the pump body (312,314), advance same in succession through pumping chambers (318,320,322) within the pump body (312,314), and then discharge same at a constant rate of discrete pulses through an outlet port (332). The pulse generator (116) and logic circuitry provide the control pulses for operating the displacer valves (360,362,364) at the proper times in the operational cycle. The delivery characteristics of the pump far exceed the performance capabilities of conventional pumps utilized for similar purposes.
