Abstract: ABSTRACT A method and apparatus is disclosed for initiat-ing the energization of a regenerative apparatus used with a particulate filter trap having a porosity effec-tive to extract particulates from the exhaust gas flow of an internal combustion engine.  The method comprises: (1) sensing the actual pressure drop across the filter trap and sensing the pressure drop across an open channel simulative filter structure: (2) converting the pressure drops to proportional voltages and ratioing the voltage of the filter trap pressure drop to the product of a constant and the voltage of the simulative filter struc-ture pressure drop; and (3) using the resultant voltage ratio to control the energization of the regeneration apparatus when the output exceeds a predetermined allow-able limit, e.g., 2-B volts.  The apparatus employs a simulative filter structure fabricated of the same mono-lithic honeycomb celled ceramic as is the filter trap, except that the structure has a controlled porosity effective to permit the passage of substantially all particulates in the gas flow therethrough.

Abstract: REMOTE INDICATING LOW BATTERY VOLTAGE            ENUNCIATOR METHOD AND APPARATUS     Abstract A low battery voltage indicator for use with remote control keyboards which are not linked by a cable to a power supply is described.  Such keyboards contain their own power and are widely used.  Remote keyboards that are infra red linked to personal computers are widely available.          Similarly, remote control TV channel selectors utilizing infra red links are extensively used and sold.  A majority-of these devices utilize a battery to power the transmitter for the infra red communication link from the remote unit to the base unit.  This invention describes an improved low voltage indicator circuit and technique that utilizes the infra red link and the key encoding circuits of the keyboard to transmit to the base station a key code indicative of the fact that low battery voltage exists.  At the base station; the key code is received and is looked up in a table that identifies the key code as a low battery voltage indication This causes the base station to flash a low battery voltage warning message on the display screen.  This replaces a low battery indicator light or buzzer on the remote keyboard unit which normally can use even more power than the infra red transmitter.  It also avoids the use of such local devices as buzzers or lights that would only worsen the low battery voltage condition already present.

Abstract: ABSTRACT OF DISCLOSURE     A machine and method for applying heat shrink labels or the like to articles such as containers having cylindrical body portions and an end portion or portions adjoining the body portion and sloping inwardly therefrom.  The label has a length such that its leading end overlaps the trailing end and a seam is formed at the overlap.  The label is secured to the article by adhesive between the leading end and the container and by adhesive between the overlapping leading end and trailing end.  The label is of a width such that it projects beyond the junction or junctions of the end portion or portions with the body portion, resulting in free standing edge or edges which are then heat shrunk or to the container by heat from an external source.  A tongue is interposed between the heat source and the seam  at each free standing edge or edges.  This tongue serves as a heat shield to moderate application of heat to the seam.  Most advantageously the end of each tongue is wedge shaped so that as it is extended it acts as a wedge to urge the free standing edge toward the article.  In a preferred embodiment of the invention heat is applied in the form of hot air in stages such that the free standing edge or edges are shrunk commencing with their junctions with the container and progressing to the outer edges whereby no air is entrapped.

Abstract: ELECTROCHEMICAL SENSOR AND MEMBRANE THEREFOR Abstract of the Disclosure Polymerizable silicon-containing com-pounds are polymerized or further polymerized in dispersed form to form cured layers or membranes when cured or polymerized in a dispersed layer upon removal of the continuous phase during cur-ing to provide a layer or membrane having unex-pectedly good oxygen and glucose-permeability without allowing the passage of electrode-sensi-tive interferants therethrough. The membranes also are permeable to cholesterol, uric acid, and lower alcohols, such as ethanol. The poly-merizable silicon-containing compounds, after dispersion in a continuous phase, such as by including an emulsifier, can be cured in any known manner during removal of the continuous phase, such as by evaporation of water from a water-continuous phase silicon emulsion or dis-persion. A glucose catalyst layer, such as glu-cose oxidase, can be bonded directly to an elec-trical signal-receiving surface, such as an elec-trode, and the membrane applied over the catalyst to form an electrochemical sensor having new and unexpected accuracy. Whole blood is applied directly onto the membrane, allowing passage of glucose and oxygen to the glucose oxidase layer while preventing passage of substantially all other electrode interferants present in whole blood. The glucose and oxygen interact with the glucose oxidase catalyst to produce hydrogen peroxide which is received immediately by the electrode surface. Since the membrane is whole blood compatible, at the conclusion of the measure-ment, the whole blood on the surface of the membrane may be rinsed or wiped off and the sensor is ready for measurement of another specimen.
