Abstract: FURNACE HEAT ABSORPTION CONTROL            Abstract of the Disclosure Furnace performance is controlled during start-up or very low load operation at a time when the minimum air flow required to be supplied to the furnace is significantly greater than that required to burn the fuel being supplied to the furnace.  Decreased furnace heat absorption is accomplished by supplying a larger quantity of the air immediately adjacent the fuel input location for the purpose of diluting the combustion gases and immediately decreasing their tempera-ture level.  Increased furnace heat absorption is obtained by introduc-ing a greater portion of the air flow into the furnace at a location remote from the fuel being burned so that the gases at the fuel location remain at a high temperature, and transfer heat to the walls, before being diluted by the incoming air.

Abstract: ACTIVITY MEASUREMENT APPARATUS FOR ANIMALS          ABSTRACT OF THE DISCLOSURE          A system for detecting estrus in cows comprising an apparatus for detecting their rate of motor acticity (movement).  A transmitter individual to a cow sends a very short burst of energy to a receiver, at a rate depending on the movement rate of the cow, which counts or records the bursts graphically.  The bursts are such as to conserve battery power, minimizing servicing thereof, a burst of a predetermined period being transmitted each time a mercury switch attached to the cow is closed.  Count rate of as much as 50% increase indicates reliably the presence of estrus, and a count rate significantly lower than normal can indicate the presence of illness.

Abstract: Abstract of the Disclosure A ripping tool positioned below the earth's surface is driven by the output of a vibrating, preferably, resonant, force transmitting beam which has lateral dimensions smaller than those of the ripping tool and is positioned below the earth's surface.  The beam is configured to have a single resonant node when restrained from vibrating at such node and is supported so that the single node is above the earth's surface and restrained from vibrating. The output of the beam is enlarged in thickness to form a hammer.  A protective gap is maintained by a tool stop between the tool and the output of the force transmitting beam.  The width of the tool stop is precisely controlled by shimming the tool stop and/or the supports for the force transmitting beam.

Abstract: TELEPHONE SIGNALLING CIRCUIT Abstract:         A telephone signaling interface enables compatible communications between a telephone station set and a key telephone system.  Separate alternating voltage control signals from the key telephone system are amplitude and polarity modulated and combined by the interface to provide ringing, switchook supervision and visual signaling to station set over a single signaling wire pair.  Current flow on the signaling pair in one direction provides visual signaling while distinguishable amounts of current flow in the opposite direction provide the supervision and ringing signals.  Interruption of the supervision current is converted by interface into an "A" lead supervision signal for the key telephone system. Voice communication between the modified station set and the key telephone system occurs over a separate voice communication pair.

Abstract: CATHETERIZATION            Abstract of the Disclosure At least part of an antimicrobial catheter for use in humans and lower animals comprises a permeable polymer. The polymer must be in contact with both the environment external to the catheter and with a liquid reservoir of antimicrobial agent flowing through the lumen of the catheter, said liquid reservoir comprising an aqueous solution containing at least a minimum lethal concentra-tion of a straight-chain carboxylic acid or carboxylic acid salt having from 4 to 9 carbon atoms.  In use, the antimicrobial agent diffuses from the liquid reservoir through the polymer and provides a zone of microbial inhibition around the external surface of the catheter. The invention thus prevents nosocomial infections re-sulting from the use of catheters by inhibiting micro-organisms at and around the placement site of the catheter when the catheter is inserted into the body of a human or lower animal.

Abstract: Abstract The invention relates to a method and a device for gas filt-ration through a barrier filter (1) comprising a plurality of filter sections (2 a-c) connected in parallel. The cleaning of the filter sections (2 a-c) is carried out in sequence.          It is known that the dust penetration immediately after com-pleted cleaning of a filter section increases substantially, due to the fact that there is no longer a filtrating dust layer on the cleaned filter material. Hereby the mean emission level of the entire filter often increases to an unacceptable level.          The object of the invention is to eliminate these emission shocks.          This object is achieved in that immediately after a cleaning operation of a filter section (2 a-c) the filtrate from this section is recycled via a return duct (14) to the crude gas duct (3) of the filer, and a filtrating dust layer is built up on the cleaned filter material. The recycling period can be controlled by measuring the particle concentration in the return duct (14).

Abstract: ABSTRACT OF THE DISCLOSURE      A method of manufacturing a device in a wafer with a P-type semiconductor, includes forming on a surface of the semiconductor body a layer of silicon dioxide doped with an N-type dopant.  The portion of the doped silicon dioxide covering the interconnect work site area is re-moved and a masking layer of an oxidation impervious medium is formed over the wafer and thereafter removed from the field areas, as is the doped silicon dioxide layer.  A thin layer of gate oxide is formed over the field areas.  A layer of conductive polysilicon is formed over the entire wafer followed by a layer of oxygen impervious masking medium. The conductive polysilicon and masking medium layers are removed from all areas of the wafer except those whereat transistors are to be formed. The wafer is exposed to an oxidizing environment under an elevated tem-perature producing a field oxide over the exposed gate oxide.  The elevated temperature of this operation drives the dopant in the doped silicon oxide layer into the semiconductor body forming doped source/ drain regions and doped first level conductor runs.  Thereafter the masking medium covering the interconnect work site area is removed and the work site area diffused with an N-type dopant.  Finally, second level conductor runs are formed on the wafer.     Heeren et al

Abstract: ABSTRACT     A tool is disclosed for controlling flow of treating fluid from a tubing string into an earth formation, in which the bottom hole pressure is less than the hydrostatic pressure of the fluid in the string.  In another application, the tool is used in conjunction with a wash tool to wash sediment out of casing perforations and slotted liners. Before the downhole operation is commenced, a slid-able piston in this tool closes off fluid outlet ports, to prevent the fluid from "gravity flowing" out of the tubing string.  The piston is held in the closed position by the co-action of an adjust-ing bolt and a compression spring.  The fluid is released from the tubing string by applying sufficient fluid pressure against the piston to overcome the spring load and thus move the piston downwardly past the fluid outlet port.   28,241-F
