Title: Surface strength tester
Inventor: MASON ROBERT J H
IPC: G01N33/34
Filed: 1988-03-29
Granted: 1994-11-29
Abstract: A surface strength tester wherein lint or like material is freed from the surface of a paper web travel-ing  passed  the  tester.  The  tester  includes  a material pick-up  head  having  an  air  bearing  surface through  and along which an air stream is  passed to generate an air bearing and  a significant  negative air pressure  between the surface and web.  The negative pressure holds the web and air bearing suface in close proximity to each other and  causes  lint  material  to  be  freed  from  the  web surface.   The freed lint material  is carried  in the air stream.  A vacuumed pick up has its inlet opening located relative to  the  air  bearing  surface  such  that  material freed  and carried  in the air stream is  sucked  into the inlet.   This material  is then collected and the time to collect a preset amount of material is measured thereby to provide  an  indication of  the  linting  propensity of  the web.

Title: Process for preparing sertraline intermediates
Inventor: QUALLICH GEORGE J
IPC: C07C49/697
Filed: 1988-06-09
Granted: 1991-07-02
Abstract: PPOCESS FOR PREPARING SERTRALINE INTERMEDIATES    ABSTRACT    A novel three-step process for preparing 4-(3,4-dichlorophenyl)-4-phenylbutanoic acid is disclosed, which involves (1) reducing 4-(3,4-dichlorophenyl)-4-ketobutanoic acid to 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid; (2) then converting the inter-mediate hydroxy acid formed in the first step to 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone, and (3) thereafter reacting the resulting gamma-butyrolactone compound with benzene in a Friedel-Crafts type reaction to form the desired final product.  The latter compound is known to be useful as an intermediate leading to 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone and ultimately, to cis-(1S)(4S)-N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthaleneamine (sertraline), which is known to be a preferred anti-depressant agent in the field of medicinal chemistry.  The aforementioned 5-(3,4-dichloro-phenyl)-dihydro-2(3H)-furanone and 4-(3,4-dichloro-phenyl)-4-hydroxybutanoic acid are both novel compounds.  There is also disclosed a novel process for converting 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone directly to 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone, as well as an alternate novel process for converting 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid directly to this same key intermediate.

Title: Windshield moisture sensor
Inventor: WILSON JAMES F
IPC: B60S1/08
Filed: 1988-12-01
Granted: 1991-07-23
Abstract: Abstract A moisture sensor to sense rain on a windshield.  The sensor members on the outboard surface of the windshield are uncoated and directly exposed to any moisture accumulation on the sensor.  Leads connect the sensor to an electrical signal generator and receiver and are insulated from each other to prevent direct electrical interconnection therebetween and subsequent shorting of the sensor circuitry.  When moisture is on the sensor, the nature of a monitorable electrical signal passing through the sensor changes and is detected.  In response to the altered signal, the windshield wipers are actuated.

Granted: 1991-01-22
Abstract: DIGITAL SPEECH CODER HAVING IMPROVED VECTOR              EXCITATION SOURCE                 Abstract of the Disclosure An improved excitation vector generation and search technique (Fig. 1) is described for a code-excited linear prediction (CELP) speech coder (100) using a codebook of excitation code vectors.  A set of M basic vectors vm(n) are used along with the excitation signal codewords (i) to generate the codebook of excitation vectors ui(n) according to a "vector sum" technique (120) of converting the selector codewords into a plurality of interim data signals, multiplying the set of M basis vectors by the interim data signals, and summing the resultant vectors to produce the set of 2M codebook vectors.  The entire codebook of 2M possible excitation vectors is efficiently searched by using the vector sum generation technique with the M basic vectors -- without ever having to generate and evaluate each of the 2M code vectors themselves.  Furthermore, only M basis vectors need to be stored in memory (114), as opposed to all 2M code vectors.

Abstract: JFM/rag NOVEL SOLUBLE POLYIMIDESILOXANES AND METHODS FOR THEIR PREPARATION AND USE                              ABSTRACT      Substantially fully imidized polyimidesiloxanes which are based on a mixture consisting essentially of a biphenyl tetracar-boxylic dianhydride and a benzophenone tetracarboxylic dianhydride, are soluble in diglyme which gives them particular utility in the micro-electronics industry.  The polymers are prepared from the mixture of dianhydrides, a difunctional siloxane monomer and an organic diamine.  Diamines can be used to provide an asymmetrical structure in the polyimidesiloxane polymer chain.  The polyimide-siloxane can be prepared with functional groups which render them directly curable.  The polyimidesiloxanes can also be prepared with functional groups which when reacted with an unsaturated compound renders the polymers curable.  The products of the invention can be used in the form of solutions in the micro-electronic industry. The polymers can also be used in wire and cable coating and to prepare films, fibers, and molded and extruded articles.

Abstract: ABSTRACT OF THE DISCLOSURE       A synthesized message storage and retrieval generates response messages by concatentating a sequence of words that have been recorded in digital memory in the voice of the operator in accordance with prescribed inflection characteristics.  By linking together phrases or words having selectively chosen inflections in the voice of the operator, the resulting vocalized message will more naturally simulate the manner of speech of the operator and thereby provide a more realistic verbalization of the message to the customer.  In accordance with the communications functionality of the operator's voice message assembly mechanism, the system performs a plurality of tasks for the operator, including automatically answering all incoming calls with a prerecorded phrase dependent on the type of call being serviced and, by means of an auxiliary audio interface with the call director, the output message can be delivered to the customer whether or not the operator is connected to the call.  In addition, rather than audibly vocalizing the message out to the calling subscriber, when retrieved from memory the contents of the message are transmitted in digital format, so that they may be captured and visually indicated to the customer via a digital display provided in the calling subscriber's telephone equipment.
