Title: Dual outlet passage hearing aid transducer
Inventor: CARLSON ELMER V
IPC: H04R25/02
Filed: 1991-04-08
Abstract: Knowles 90919 DUAL OUTLET PASSAGE HEARING AID TRANSDUCER            Abstract of the Disclosure An improved high-frequency characteristic is achieved, in an otherwise conventional hearing aid receiver transducer by connecting each of the acoustic chambers on the two sides of the receiver diaphragm, in the receiver housing, directly through an outlet port and a sound transmission tube coupled into the ear canal of the hearing aid user; phase reversals due to resonances in the receiving acoustic chambers and tubes produce a high pass band in the output of the receiver as applied to the user's ear.  An acoustically transparent contamination stop prevents contaminants (e.g. cerumen) from reaching the transducer motor but does not interfere with acoustic performance.

Filed: 1991-04-26
Abstract: This invention relates to a vending machine and more particularly to an interactive machine which is usable to dispense a variety of personalized products including greeting cards and/or visual and audio media as selected by a customer.  It is arranged to accept inexpensive stock products and to effect modifications such as to provide highly attractive personalized products.  A machine constructed in accordance with the invention preferably includes an enclosure with selection and payment means on the outside thereof and with storage and handling means on the inside thereof, all coupled to a computer equipment which is on the inside of the enclosure and which is programmed to facilitate a customer's creation from among types of products to be delivered and the desired mode of personalization thereof and to deliver a completed personalized product to d respectable from which it may be removed by the customer.  An important feature of the invention relates to the provision for manufacture of personalized greeting cards from "white paper", i.e. paper stock of any color and of any weight and in sheet or roll form, particulary including, for example, heavy paper stock or cardboard such as 59 pound stock used for high quality greeting cards, to provide a completed card, the machine imprints on such stock both graphics and text as selected by a customer to provide a personalized card of very high quality. With this arrangement, all stock is used.  There are no expensive preprinted forms which might go unused and waste is eliminated.  Another very important advantage is that a great many graphics and text formats may be permanently stored in digital form as on hard discs, tape or CD ROMs, to provide customers with much wider selections of graphics and text formats.

Title: High activity, high yield tin modified platinum-iridium catalysts, and reforming process utilizing such catalysts
Inventor: BAIRD WILLIAM C JR
IPC: C10G35/09
Filed: 1991-11-26
Abstract: ABSTRACT OF THE DISCLOSURE           Tin modified platinum-iridium catalysts provide high yields of C5+ liquid reformate in catalytic reforming,  concurrent with high activity.   In particular,  the tin modified platinum-iridium catalysts are of unusually high selectivity,  as contrasted with known  iridium promoted platinum catalysts.  The high selectivity is   manifested in reforming  a naphtha feed  in a reactor charged to capacity with the catalyst, but particularly when used in the dehydrocyclization zone, or tail reactor of a series of reactors, while the lead reactors of the series  contain  a non tin-containing  platinum catalyst,  especially a platinum-iridium,  or  a  platinum-rhenium catalyst.   The  tin  modified platinum-iridium catalysts are also highly active, with only moderate loss  in  the  high  activity  for  which  iridium  stabilized  platinum catalysts are known.

Abstract: PROCESS FOR CONVERTING HEXAFLUOROARSENIC ACID OR ANY SALT THEREOF TO ARSENIC ACID OR SALT THEREOF     WHICH CAN THEN BE RENDERED NONHAZARDOUS              ABSTRACT OF THE DISCLOSURE        The present invention provides a process for the conversion of hazardous hexafluoroarsenic acid or any salt thereof to arsenic acid or salt thereof which can be rendered nonhazardous.  In particular, the hexafluoroarsenic acid or salt is converted to arsenic acid or salt which can be converted to a water insoluble salt.  Known insolubilization and stabilization technology then renders the material nonhazardous.        The present process involves converting hexafluoroarsenic acid or salt thereof contained in an aqueous mixture to arsenic acid or salt thereof.  The process  comprises the steps of:  (a) adding acid selected from the group consisting of sulfuric acid, arsenic acid, perchloric acid, and mixtures thereof to the aqueous mixture in an amount sufficient to catalyze the hydrolysis of the hexafluoroarsenic acid or salt thereof and raising the temperature of the aqueous mixture before, during, or after the acid addition sufficient to remove substantially all of the hydrogen fluoride in subsequent step (b);  (b) passing an inert gas through the heated acid mixture steam in a quantity sufficient to remove substantially all of the hydrogen fluoride in the heated acid mixture from the heated acid mixture; and  (c) separating substantially all of the hydrogen fluoride from the heated acid mixture whereupon the hexafluoroarsenic acid or salt thereof converts substantially to arsenic acid or salt thereof.   6878k

Title: Snow trail grooming apparatus
Inventor: LABA JOHN
IPC: E01H4/02
Filed: 1992-03-26
Abstract: ABSTRACT OF THE DISCLOSURE          SNOW TRAIL GROOMING APPARATUS             A snow trail grooming apparatus comprises a main frame which is supported at a forward end on on a pair of skis and at a rearward end on a transverse flat pad extending across the width  of  the  frame.   At a forward part of the frame is provided a plurality of  cutting  discs with the disc surface having a forward edge extending substantially in a direction of travel of the frame and a rearward edge curving rearwardly and inwardly toward a centre of the frame tending to cut the snow as it moved forwardly and then direct the snow rearwardly and inwardly.    The  disc  is  thus  provided  on two separate axles inclined  forwardly and  inwardly  from the  sides of the frame toward a central forward apex between the two axles.  The axles are attached to a support frame across the width of the main frame  which  can  be  lifted  at  either  side  independently or jointly to a transport  position.   Rearwardly of the cutting discs is provided  an  accumulator  section  with a  transverse blade and a semi cylindrical culvert section mounted on top of the  blade  to provide a rolling action of snow lifted by the blade.   The cut snow is thus lifted by the blade in areas of excess snow and rolled in the accumulator section and can be deposited  from the  accumulator  in  areas  of  reduced  snow quantity.   The rear  flat  pan acts  to slightly compress and finally level the snow released from the accumulator.

IPC: G02B6/00
Filed: 1991-11-29
Abstract: A method of identifying optical cables by sending optical signals to optical cables C1, C2 via transmission means (device 11), applying an external signal via a signal application device (16) to a particular optical cable C1 that is to be identified, and monitoring a change in the signal by reception detection means (device 11). Harmonic wave signals having a large frequency shift and a large level difference are compared in a relationship between the particular optical cable C1 to which the external signal is applied and the adjacent optical cable C2 neighboring to which the external signal is crosstalking. The particular optical cable C1 is identified without developping any error.
