Title: Process for producing polyarylene sulfide fiber and thereby obtainable polyarylene sulfide multifilament yarn
Inventor: WELLENHOFER HERBERT
IPC: D01F6/76
Filed: 1993-06-17
Abstract: Abstract Process  for  producing  polyarylene  sulfide  fiber  and thereby obtainable polyarylene sulfide multifilament yarn There is described a process for producing fiber from polyarylene sulfide comprising the steps of: a) melt spinning a polyarylene sulfide into a gas, in particular  into  air,  at  a  pump  rate  of  at  least 0.5 g/(min x hole), b) forcedly cooling the spun filaments in the spinning column by quenching with a blown gas, c)  taking off the filaments at a speed of more than 800 m/min, preferably between 1000 and 5000 m/min, d) intermediately storing the spun filaments, e) drawing the spun filaments in two stages in an after-treatment stage by e1) drawing in the first stage at a temperature between the glass transition temperature and the yield tempera-ture and to such a degree that the filaments are vir-tually completely drawn and e2) drawing in the second stage at a temperature above that of the first stage and below the crystallite melting point temperature of the filaments to such a degree that the filaments are additionally drawn by 5 to 30% and in such a way that no mechanical contact is involved in the heat transfer of the second drawing stage and the drawing tension is 11 to 25 cN/tex, based on the true linear density, and f) immediately thereafter heat setting the drawn fila-ments.  The process of the invention is suitable for producing fiber having very good mechanical properties, such as tensile strength and transverse strength. The process is notable for high productivity,  since high takeoff speeds are employed and subsequent drawing is carried out in two stages.

Title: Pneumatic outlet for railcars
Inventor: DUGGE RICHARD H
IPC: B61D7/02
Filed: 1993-07-22
Abstract: Abstract of the Disclosure An improved pneumatic outlet (10) is for use on a railcar (C) for discharging a lading from a hopper (H) of the railcar.  The outlet comprises an integrally formed bottom cover (12) extending the length of the outlet.  A pair of outlet valves (50A, 50B) are installed in the cover.  The valves are mounted on respective valve shafts (54A, 54B) and are installed in the cover in a diagonal arrangement.          Accordingly, each valve allows discharge of lading from one side of the hopper.  A bulkhead (40) is also installable in the cover and supports an inner end  of the respective valve shafts.  The cover is severable into two sections (36A, 36B). one of the sections is reversible with respect to the other section.  Thereafter, the two sections are joined together to form a unified cover through which lading flows during discharge.  The bulkhead fits within the reunified cover such that no gaps or other deformities are present which would collect material that may contaminate a lading.
Patent CA-2102065-A1 (CA)
Inventor: JACUS ROBERT J
IPC: H01M50/40
Filed: 1993-10-29
Abstract: During repeated cycling of alkaline manganese dioxide cells, it is critical to ensure that adequate barrier protection is formed and maintained between the anode and cathode of the cell to prevent shorts from occurring between the cathode and the anode. However, the potential also exists for anodic zinc to migrate via the absorbent separator and create a short path to the cathode. To prevent this, cells can be fabricated whereby a separator barrier is placed into the cells, a hot melt sealant is metered into the cell so that the sealant flows under the separator barrier, the separator barrier is pushed down and seated into the hot melt. The end result is a separator barrier which is sealed at the bottom of the cell and at both sides of the separator barrier and virtually eliminates shorts from developing between the electrodes.

Inventor: TARCHA PETER J
IPC: G01N21/65
Filed: 1993-09-09
Abstract: ABSTRACT OF THE DISCLOSURE     A method, composition, device, apparatus, and kit for the determination of the presence or amount of an analyte by monitoring an analyte-mediated ligand binding event in a test mixture which contains the analyte to be assayed, a specific binding member, a Raman-active label, and a particulate having a surface capable of inducing a surface-enhanced Raman light scattering. The test mixture is illuminated with a radiation sufficient to cause the Raman-active label in the test mixture to emit a detectable Raman spectrum. The differences in the detected surface-enhanced Raman scattering spectra are dependent upon the amount of the analyte present in the test mixture. Thus, by monitoring these differences, the presence or amount of the analyte are determined.

Title: Apparatus for pumping medium consistency pulp
Inventor: FUNK ERWIN D
IPC: F04D7/00
Filed: 1993-12-02
Abstract: ABSTRACT OF THE DISCLOSURE      Medium consistency cellulose pulp is pumped utilizing an eccentric screw pump rotor, including pulp with a consistency of about 10% and a freeness of at least about 700 ml CSF.  An elongated feed screw, having a helical flight, is attached by a coupling to an eccentric screw pump rotor within a housing containing the feed screw and rotor.  The housing has a transition adjacent the coupling, preferably a stepped transition.  The feed screw includes a hollow tube portion surrounding the coupling so that the coupling does not provide an obstruction to slurry being conveyed by the feed screw toward the rotor, and the hollow tube portion also includes a thickened section of the helical flight and a number of agitator pins which prevent the pulp from compacting at the transition.

Abstract: A method is disclosed for the manufacture of screen cylinders, e.g. for removal of debris such as sand, rock, metal, resin etc. from a liquid suspensionused in the pulp and paper industry. The screen is of the type having a plurality of slot passages, each extending axially the entire axial length of the cylinder. According to the invention, the width of the slots is controlled by determining the physical structure of the screen, particularly the overall thickness of the screen and the backing reinforcement ribs, prior to the rollingof the screen plate into a cylinder. A table of a number of different sizes is included showing the practical range of application of the invention. The invention allows the use of standard cutters used in the milling of the slots for the production of screens with much narrower slots to obtain an improved degree of removal of contaminants without having to use specially thin cutters. Screens produced by the method are also claimed.
