Abstract: Abstract Ostomy Aprons are needed to shield the skin of ostomates from ostomy appliances. (An ostomate is a person whose colon, or a part of colon, is removed, and who secretes his body waste through a surgically created opening called stoma.  There are devises used for this purpose but they are impractical. One is a device made of cloth, which is pulled over an ostomy bag much like a dress. The problem with this artifact. is that. it doesn't stay on even when the fitting is tight. Also it makes the access to an open-end bag awkward and, because of that, the shielding cloth becomes readily soiled. Another device is an inside pocket. in a brief; but the problem with this device is that the pocket is in place for some patients but out of place for the others. The ostomy apron, is easy to apply and is more efficient and less expensive than the other devices used for this purpose.

Title: Alkaline leaching of galvanized steel scrap
Inventor: LEEKER JERALD W
IPC: C22B19/20
Filed: 1991-10-04
Abstract: Caustic dezincing galvanized steel scrap. A dezincing plant includes a plurality of tanks (14, 16, 18) interconnected in series with steel scrap sequentially being moved through each of the tanks. The tanks (14, 16, 18) contain a caustic leaching solution including an oxidant with the leaching solution being circulated through each of the tanks (14, 16, 18) in a direction opposite to the movement of the scrap. Fresh scrap initially is exposed to a partially depleted leaching solution with the oxidant concentration of the leaching solution increasing as the scrap moves through the series of tanks (14, 16, 18). Leaching solution depleted of its oxidant is transferred to an electrolytic cell (22) where zinc is removed and plated as metallic zinc powder onto a cathode. The leaching solution is recycled by removing zinc. The chemistry of the leaching solution is controlled so that sufficient free caustic is present to prevent passivating zinc coating on the scrap. Oxidant is added to the recycled solution and the caustic concentration is adjusted, if necessary, to have a total caustic concentration of at least 5 M and the recycled solution is returned to the last tank (18). Compressed scrap bales are dezinced and ready for use as a melting furnace charge material. <IMAGE>

Abstract: A multichannel radiotelephony system provides two way   cordless   communications   with   a   plurality   of multichannel transceivers portable within a coverage area comprised by a plurality of cells, each associated with a base  station  and  antennas,  such  as  to  permit  channel frequency reuse in cells within the coverage area.  For at least part of the coverage area,  the locations of the antennas within the cells and the locations of the base stations  are  independently  mapped,  the  antennas  being associated with active  antenna  systems  and  the  active antenna  systems  being  connected  to  the  base  stations utilizing broadband transmission by means of a fixed bi-directional signal distribution network.   The network is connected to the base stations and the antenna systems through  suitable   interfaces   incorporating   frequency translation so that available frequency bands in the signal distribution network which will normally be shared with other services, may be utilised.  Plural base stations may be co-located.  The radio link to the transceivers may be frequency or time division multiplexed, but communication over the network will normally be frequency multiplexed, using separate bands for transmission and reception.

Title: Process for uniformly integrating a solid charge within a porous substrate
Inventor: LELUAN JEAN-LUC
IPC: B29L31/58
Filed: 1992-06-16
Abstract: The process is particularly well suited to the manufacture of composite materials, where a fibrous reinforcement texture is to be impregnated by a densifying matrix, and comprises the steps of: - preparing a slurry containing a solid charge in the form of finely divided particles dispersed in a carrier liquid, which preferably contains an organic compound, - placing a substrate inside an enclosure, - creating a vacuum inside the enclosure, and - causing the slurry to pass through the substrate by means of a pressure difference.      Uniformity of charge integration is ensured by forcing the slurry to pass through the substrate several times, in successively opposite directions. The concentration of solid charge in the slurry can be determined as a function of an intended charge percentage by volume in said substrate.

Title: Secure keyless entry system for automatic garage door operator
Inventor: DUHAME DEAN C
IPC: G07C9/00
Filed: 1992-08-26
Abstract: ABSTRACT         A secure, keyless secondary transmitter unit for use in an automatic garage door operator transmits a code set by a code setting device as modified by digits entered at a keyboard.  A controller constructs an identification code by inverting bits of the code set by the code setting device  that  correspond  to  entered  digits.    A  radio frequency transmitter transmits this altered code in the manner of known automatic garage door operators.   Thus operation of keys corresponding to the bits that differ between the receiver code and the secondary transmitter code  controls  the  door.  The  keyboard  preferably  also includes an entry complete key indicating entry of the complete digit sequence and a clear key to restart the digit  sequence.    A  lamp  connected  to  the  controller illuminates the keyboard upon operation of  any key at the keyboard and is turned off if no key is operated in a predetermined period of time.   Further operation of the entry complete key within this predetermined period of time causes the controller to again construct and transmit the same  code.    This  secure  keyless  transmitter  unit  is believed to be as secure as the primary transmitter units, even when permanently mounted outside the controlled door.

Inventor: CUNNINGHAM DONALD M
IPC: F24C7/04
Filed: 1992-10-07
Abstract: An electric range (R) has a glass/ceramic cooking top (S) upon which rests a cooking utensil. Electrical heating apparatus (10) comprises an electrical resistance heating element (12) to which an electrical current is supplied. This causes the heating element to generate heat. A heat sink (16) is interposed between the heating element and the cooking top for absorbing heat energy from the heating element and for spreading the energy under the surface area of the top by conduction. The heat sink is of an electrically insulative, translucent, aluminum nitride material or similar high thermal conductivity material. An insulation cake (20) supports the heating element and heat sink adjacent an underside of the cooking top and provides both electrical and thermal insulation. A pan (24) supports the insulation cake, the heating element (12) and the sink (16) in intimate contact with each other and the underside of the cooking top for maximum heat transfer by conduction. The heating element also functions as a temperature sensor responding with a change in electrical resistance to a change in temperature of the heating element as influenced by the cooking process. The change in electrical resistance is the input for an electronic control which prevents excessive temperature of the glass/ceramic cooking top. <IMAGE>
