Abstract: A diaphragm assembly (10) is provided around the doors (11) of adjacent railway cars (12) and together adjacent diaphragm assemblies (10) enclose the passageway between adjacent railway cars (12).  Each diaphragm assembly (10) includes a mounting plate (15) having vertical sections (17, 18) at the side of door (11) and an arch portion (19) above door (11) mounted to a car (12). The mounting plate (15) is of a predetermined lateral width and carries side portions (22) of a flexible membrane (21).  A bridge portion (23) of flexible membrane (21) extends between side portions (22) and is attached to a face plate (25) which has vertical sections (26, 27) at the side of door (11) and an arch portion (28) above door (11).  The face plate (25) has a predetermined lateral width greater than the width of mounting plate (15).  Face plates (25) of adjacent cars (12) are adjacent to each other and a seal assembly (40) may be provided between the arch portions (28) thereof to prevent liquid from entering the passageway.          At the bottom of the diaphragm assembly (10), a sill membrane (70) is attached to a sill plate (29) which is mounted between the vertical sections (26, 27) of the face plate (25).  The sill plate (29) is attached to push rods (51) of the car (12) by a connector assembly (50) including bushings (57, 60) which minimize the noise of the connec-tion.  A walk plate (80) is hingedly connected to the sill plate (29) and is positioned above the sill membrane (70) to provide for ease of passage from one car (12) to another.

Title: Electronic article surveillance system incorporating an auxiliary sensor
Inventor: LIZZI PHILLIP J
IPC: G08B13/24
Filed: 1990-12-21
Abstract: Abstract of the Disclosure To reduce the occurrence of false alarms, the disclosed system incorporates an auxiliary sensor for detecting the presence of a shopper passing through the electronic article surveillance device, such that the device is operated continuously, and the auxiliary sensor is used to enable external alarms of the device only upon detecting the shopper's presence.          Thus, while the device continuously monitors field-induced signals which are received, activation of the external alarm is permitted only when a shopper passes through the security device and is detected by the auxilliary sensor.  Sounding of the alarm is then based upon an analysis of the data received at and just prior to the detected approach of the shopper to be monitored, eliminating phantom alarms while significantly reducing false alarms and merchandise-activated alarms.

Title: Process for the separation of arsenic acid from a sulfuric acid-containing solution
Inventor: PONCHA RUSTOM P
IPC: C02F1/52
Filed: 1992-04-23
Abstract: PROCESS FOR THE SEPARATION OF ARSENIC ACID  FROM A SULFURIC ACID-CONTAINING SOLUTION              ABSTRACT OF THE DISCLOSURE        The present invention provides a process for the separation of arsenic acid from a solution which comprises sulfuric acid, water, and arsenic acid.  In step (a), the solution is reacted with copper or a copper-containing compound in an amount sufficient and at a temperature sufficient to produce copper arsenate.  In step (b), an alkali solution is added to the solution resulting from step (a) in an amount sufficient to precipitate the produced copper arsenate and solubilize the sulfate salt of the alkali.  In step (c), the precipitated copper arsenate is separated from the solution resulting from step (b).  The separated copper arsenate can then be used in the preparation of intermediates which can be converted to wood preservatives.        In step (d), a soluble ferric-containing compound is added to the solution resulting from step (c) in an amount sufficient to reduce residual arsenic in the solution.  In step (e), the ferric arsenate formed is separated from the solution resulting from step (d).  The separated ferric arsenate can be disposed of properly.  The filtrate comprises about 85 to about 90 percent by weight water, about 10 to about 15 percent by weight sodium sulfate, and below about 0.79 parts per million of arsenic; this filtrate is considered nonhazardous and can be discharged to waste ponds.   6881k

Abstract: On a mis au point un procédé et un appareil de détection de collisions, destiné à détecter les infractions aux règles du code dans des paquets de données codées selon le code Manchester. Les signaux delta0 = S2n - S2n-1, delta1 = S2n+1 - S2n, delta2 = S2n+1 - S2n -1, sigma0 = S2n + S2n -1, sont déterminés au temps nT où S2n -1 et S2n constitue la paire binaire du code Manchester, représentative du énième bit dans un flux de données ayant une période binaire T. Le traitement de ces signaux permet la détection de la plupart des collisions, puisque les règles de codage Manchester sont trangressées pendant plus de la moitié du temps dans le signal formé par les paquets venant en collision. Afin d'assurer une détection de collisions à 100 %, un préambule utilisant une infraction intentionnelle au code Manchester dans la configuration 10 11 01 10 est avantageusement utilisé dans chaque paquet de données, et une collision est signalée lors de la détection de deux infractions de codage ou plus.
