Title: Disposable absorbent garment having elastic outer cover and integrated absorbent insert structure
Inventor: KIELPIKOWSKI DAVID P
IPC: A61F13/514
Filed: 1987-12-22
Granted: 1991-07-16
Abstract: ABSTRACT      An anatomically form-fitting, generally self-adjusting disposable absorbent garment comprises a breathable elastomeric nonwoven laminar outer cover, resiliently stretchable preferably in a cross-body direction from about 20% to about 200%, including a pair of leg openings, front and rear waist sections together defining a waist opening, a crotch section situated between the leg openings and front and rear panels separated by the crotch section.  An absorbent insert structure, substantially superposable on the front and rear panels and the crotch section, includes a liquid impermeable barrier and a liquid permeable bodyside liner, with an absorbent composite disposed therebetween.  Longitudinally opposed ends of the absorbent insert are attached to the waist sections, integrating the insert into the outer cover while allowing substantially unrestricted functional stretchability thereof.  A pair of supplemental leg elastic members are applied to the outer cover in an operatively tensioned state relative thereto and extend around outermost portions of the leg openings. Either of the leg and waist elastics comprise breathable elastomeric nonwoven laminar fabric strips which are resiliently stretchable preferably from about 20% to about 300%, providing cushioned, cloth-like gathering of the garment about the body of a wearer.

Abstract: Abstract A heat exchanger for cooling a machine, such as a mechanical gear or some other transmission component, hydraulic pump, motor or clutch, compressor, internal combustion engine or like machine, which comprises a housing in which movable, mechanical elements, which are driven when the machine is working are housed, and which encloses a liquid medium, such as a lubricating or hydraulic liquid. The heat ex-changer is mounted in the outer wall of the housing and comprises two chambers which are mututally separated by a liquid-impervious partition wall which comprises part of the housing wall. The inwardly located chamber is through-passed by the liquid medium enclosed in the housing, while the outwardly located chamber is through-passed by a cooling medium. The heat exchanger is so positioned that a pressure difference is created between the inlet and the outlet of the inwardly located chamber under the influence of movement of the movable mechanical elements therewith obviating the need of a separate pump for driving the medium to be cooled through the heat exchanger.

Abstract: EXTRUDED ARTICLE AND METHOD OF MAKING SAME                   Abstract An extruded article is provided comprising a base element, and at least one rib element attached to the base element along its entire length. The rib element is narrower at its attachment end than at its free end, and is undulated.         The article is formed by extruding an extrudable plastic mass having a conformable state and a nonconform-able state. The extrusion rate of the free end of the rib element is sufficiently faster than that of the base element. The free end of the rib element will therefore undulate as the structure is extruded. The free end of the rib element is permitted to undulate without distortion of the base element while the plastic mass is in the conformable state. The plastic mass is then converted to the nonconformable state while maintaining the undulation in the free end of the rib element.

Abstract: METHOD OF MAKING A CURRENT SENSOR               ABSTRACT   A method of making a current sensor device is disclosed wherein a sensor, having a magnetoresistive element configured into a bridge, an insulating substrate and a conductive member are sub-assembled and then the sub-assembly is heated to bond the components together.  The bridge is attached to a first substrate having a first layer of insulation with first  vias  therein  in which are  deposited  first  elements  of  solder projecting beyond  the first layer of insulation.   Second elements of (e.g.)  solder  are  deposited  in  second  vias  in  a  second  layer  of insulation  on  the  second  substrate.    When  the  components  are sub-assembled, the first elements rest on the second elements to provide a clearance between the first and second layers of insulation.  Heat is applied to the sub-assembly in a controlled manner so that the (solder) elements melt sufficiently to cause a degree of self-alignment between the  bridge and  the  conductive member  and  to cause  the bridge to be disposed at a predetermined distance above the conductive member.

Abstract: Abstract A process is described for removing contaminants from a contaminant-laden solution of dialkyl ethers of polyethylene glycols (polyether solvent) by mixing the solution with an aqueous base solution.  The mixture produces at least two liquid phases of different densities, which are then separated from each other.  The lighter liquid phase is pedominantly the polyether solvent while the heavier liquid phase is predominantly the aqueous base solution and the contaminants.  The process is particularly useful in removing triethylene glycol and other glycol-based dehydration solvents.

Title: Deep fat frying apparatus having an improved cooking fluid filtration system
Inventor: GROB JAMES T
IPC: A47J37/12
Filed: 1989-03-08
Granted: 1992-12-29
Abstract: ABSTRACT        A multi-frypot, deep fat frying assembly is formed by operatively interconnecting a filtered, multiple frypot cooking module with one or more nonfiltered, multiple frypot cooking modules, each module having headered cooking fluid supply and drain piping systems disposed within its outer housing.   To form the ganged frypot assembly, the module housings, with appropriate side panels removed, are placed in  a  side-by-side  orientation  and  the adjacent  headered piping systems are connected to one another to form in the assembly  common  supply and  drain headers.   The filtered module is provided with a roll-out,  self-contained filter unit which may be moved into and out of the filtered module housing directly beneath its frypots, the filter unit having a cooking fluid receiving container which carries a filter pump that may be quick-connected to the supply header.  The drain header in the filtered module has a pivotally mounted outlet tube which may be pivoted rearwardly to operatively position  it  over  the  receiving  container,  or  pivoted forwardly to position it over a suitable disposal container positioned at the front of the filtered module's housing.  A spring loaded detent member is used to releasably lock the outlet tube in either its forwardly or rearwardly pivoted position.   The outlet side of the filter pump is provided with the diverter valve operative to circulate cooking oil through the pump and filter to provide the assembly with a cooking oil "polishing" cycle.

Abstract: A three component system, for use in association with one another, in the treatment of malignant diseases comprises:  a first component which is a substance or conjugation of substances characterised by (a) one or more molecular configurations that are complementary to molecular configurations associated with malignant cells, such that the first component tends to localise selectively at sites of malignant cells and (b) additionally by one or more catalytic sites; a second component which is able to bind to such part of the first component so as to inactivate the catalytic site of the first component and/or accelerates the clearance of the first component from the blood when the first and second components are administered clinically and a third component which is a substrate for the catalytic site on the first component, one of the end products of the catalysis being a substance which is more cytotoxic to malignant cells than the third component.  The use of the second component reduces the extent to which the cytoxic drug is released from the third component in regions of a patients body remote from the target tumour.
