Granted: 1992-04-07
Abstract: ABSTRACT OF DISCLOSURE     Disposable mat material comprising an abrasion resistant pervious layer of a ncn-woven web of bonded filaments and an absorbent layer of microfibres, the pervious and absorbent layers being bonded intermittently characterised in that the bonds penetrate through the pervious layer and join the fibres in that layer with those in the absorbent layer.  Thus water, for example, on the feet of a user, rapidly penetrates to the absorbent layer from the outer abrasion resistant layer.  The bond areas not only aid the rapid absorbence, but also provide 'pockets' giving an enhanced roughness.

Title: Absorbent article having leakage resistant dual cuffs
Inventor: DRAGOO JERRY L
IPC: A61F13/15
Filed: 1987-10-07
Granted: 1991-10-15
Abstract: ABSTRACT       An integral disposable absorbent article such as a diaper provided with an absorbent core, a liquid impervious backsheet, an elastically contractible gasketing cuff preferably formed by a gasketing flap and a flap elastic member, a barrier cuff having a flap portion and a channel portion comprising a proximal edge and a distal edge, and a liquid pervious topsheet. The topsheet extends outwardly toward the edge of the absorbent core and terminates inwardly of the proximal edge. A seal means for adjoining the proximal edge to the gasketing flap is positioned along the proximal edge so as to provide a leakage-resistant seal along the proximal edge. The barrier cuffs may be provided with spacing means for spacing the distal edges away from the liquid-receiving surface so as to enhance the containment characteristics of the barrier cuffs. Thus, body exudates which wick through and along the topsheet are prevented from flowing to the edges of the diaper and underneath the barrier cuffs because of the seal formed along the proximal edges and because the topsheet terminates inwardly of the proximal edges.

Abstract: Abstract A local oscillator is arranged in a Colpitts type configuration in which an amplifying device such as a bipolar transistor or field effect transistor having a control electrode (base or gate electrode) is coupled to a first electrode (emitter or source electrode) defining the end of a conduction channel through an oscillation conditioning network for conditioning the device to oscillate in a given range and also to a frequency determining network including a first varactor diode responsive to the tuning voltage and an inductance element coupled in series between the control electrode and signal ground, and in which the output is taken at a second electrode (collector or drain) defining the other end of the conduction channel.  A range extending circuit including a second varactor diode responsive to the tuning voltage is coupled between the control electrode and signal ground for ensuring that the oscillator operates reliably at both ends of the tuning range.

Title: Method for producing mold-shaped ceramic bodies
Inventor: LAROCHE E ALLEN JR
IPC: C04B35/65

Granted: 1992-10-20
Abstract: TITLE            METHOD FOR PRODUCING MOLD-SHAPED CERAMIC BODIES                      APPLICANT            LANXIDE TECHNOLOGY COMPANY, LP                       INVENTOR                 Evans Allen LAROCHE, JR.                  ABSTRACT      A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a gas-permeable, conformable material to a shape-defining surface of a shaped parent metal.  The gas-permeable material, when set or stable, provides a mold with a shaped surface which is defined by, and is therefore substantially congruent to, the shape-defining surface.  Upon heating, the parent metal melts and flows from the mold into a receptacle without disturbing the mold.  Oxidation reaction product is then grown by oxidation of the molten parent metal with a vapor-phase oxidant to form an oxidation reaction product which grows into the mold cavity and is shaped by it.  A ceramic body is recovered from the mold and has substantially the same shape as the pattern section of the original shaped parent metal.

Title: Uv-base ceramic paint composition and method of forming a glass sheet with a uv-base ceramic paint thereon
Inventor: BOAZ PREMAKARAN T
IPC: C03C17/22
Filed: 1988-10-13
Granted: 1996-09-10
Abstract: This specification is directed to a UV-base ceramic paint composition and a method of forming a glass sheet with a UV-base ceramic paint thereon. The method has the following steps. A UV-base ceramic paint is applied to the glass sheet. The UV-base ceramic paint includes selected ceramic paint components along with, as a new component thereof, finely divided zinc metal powder. The glass sheet is subjected to UV radiation and then heated to a temperature which softens the glass sheet sufficiently so that the glass sheet can be formed. The glass sheet and the ceramic paint thereon are engaged with a fiberglass covered forming die to form the heated glass sheet to a desired shape. The forming die is removed from engagement with the glass sheet. The finely divided zinc metal powder addition to the ceramic paint is credited with being effective to prevent sticking of any of the ceramic paint to the forming die. The glass sheet is cooled to obtain a formed glass sheet with a ceramic paint thereon.
