Title: Process and apparatus for applying chilled electrostatically charged particles to the surface of a large metal article
Inventor: HOFFMAN REINHOLD
IPC: B05D1/06
Filed: 1986-05-26
Granted: 1990-05-08
Abstract: PROCESS AND APPARATUS FOR APPLYING CHILLED ELECTROSTATICALLY CHARGED PARTICLES TO THE SURFACE OF A LARGE METAL ARTICLE ABSTRACT OF THE DISCLOSURE The process described herein comprises the application of chilled particles such as polytetrafluoroethylene generally marketed under the trade mark "TEFLON", graphite, molybdenum sulfite, boron nitride, etc., to a metal surface having crevices or pores therein. With the metal heated to expand the crevices or pores and the particles chilled to contract them, the particles will be locked into the pores when both the metal and the particles come to equilibrium temperature with the particles thereby expanding and the pores contracting. The process described herein is directed to such an application of chilled particles to expanded pores in large metal objects such as for example, large rolls. The large object is rotated on it linear axis while maintained at the desired raised temperature and the particles are given an electrostatic charge and chilled prior to their application to the metal surface. Apparatus for effecting this application of electrostatically charged chilled particles is also described.

Title: Protection apparatus for patient-implantable device
Inventor: WINSTROM WILLIAM L
IPC: A61N1/37
Filed: 1986-09-29
Granted: 1991-10-01
Abstract: ABSTRACT OF THE DISCLOSURE           An electrical circuit is connected in series with a lead of an implantable heart pacemaker between the pacemaker and the heart to protect the pacemaker against high voltages and currents produced by defibril-lators and other sources.  The electrical circuit has a sensing resistor arranged between two normally conduct-ing field effect transistors (FETs) all in electrical series with the pacemaker lead.  When the voltage drop across the sansing resistor exceeds a predetermined positive or negative amplitude, a transistor becomes conductive and turns off the normal conduction channels of the FETs.  An alternate, electrically conductive high-impedance path is switched in to limit the current flow to the pacemaker until the magnitude of the voltage across the sensing resistor drops to a safe level.  The transistor then becomes non-conductive and the FETs become conductive re-establishing the normal low-impedance conduction path and effectively switching the alternate high-impendance path out of the circuit.

Title: Reliable pulp consistency measurement using line loss  technique
Inventor: SHERMAN MICHAEL I
IPC: G01N11/00
Filed: 1987-06-23
Granted: 1996-01-23
Abstract: The consistency of a medium consistency (e.g. about 6-18 percent) paper pulp (e.g. Kraft pulp) may be accurately determined by determining the pipe line friction drop.  The pulp is deaerated with a fluidizing pump, and pumped into a conduit.  A pair of spaced pressure taps are provided in the conduit, and they are operatively connected to a differential pressure transmitter, such as one having a piezoresistive sensor.  The transmitter may be calibrated to correspond to a desired consistency, or the temperature and flow rate of the pulp may be measured and from this, utilizing the Bodenheimer equation, the consistency may be calculated.  The method and apparatus are much more effective in determining consistency than are conventional optical and mechanical techniques, for medium consistency pulp.

Abstract: STATIC POWER CONVERSION METHOD AND APPARATUS               ABSTRACT OF THE DISCLOSURE     A high efficiency power converter is achieved utilizing a resonant DC link between a DC source, such as a converter rectifying power from an AC power system, to a variable frequency voltage source inverter.  A resonant circuit composed of an inductor and capacitor is connected to the DC power supply and to a DC bus supplying the inverter and is caused to oscillate stably at a high frequency to provide a uni-directional voltage across the DC bus which reaches zero volts during each cycle of oscillation of the resonant circuit.  The switching devices of the inverter are controlled to switch on and off only at times when the DC bus voltage is zero, thereby eliminating switching losses in the inverter.  The resonant circuit can be caused to oscillate utilizing pairs of switching devices in the inverter or a separate switching device across the capacitor, which again are caused to switch on and off only at times of zero voltage on the DC bus.  For AC to AC conversion, enabling bi-directional power flow, the switching devices of the power source which converts AC power to DC power may have switching devices which are also switched only at the times of zero voltage so that switching losses in these devices is also minimized.

Abstract: For the purpose of producing filled foil-containers adapted to stand upon their bases, container-parts having tubular parts are initially deep-drawn, in a strip of foil, on each side of a centreline running in the direction of travel, the said tubular parts running towards the edges of the foil but terminating at a distance therefrom.  There-after, the foil-parts lying on each side of the centreline are heated and are folded up about the said centreline, which thereby becomes a fold-line to form open containers which are then sealed, at a first sealing station around their peripheries, except for the perpheries of the upwardly projecting tubular parts.  The edges of the foil are then spread apart in the vicinity of the said tubular parts, through which the containers are filled.  The spreading is released and the containers are sealed, in a second sealing station in such a manner as to close the peripheries of the said tubular parts also.  Opening-aids are then made in the vicinity of the tubular parts thus formed and the filled containers are separated individually or into groups.  An apparatus of this kind consists of a supply-station with a roll of foil a conveyor a deep-drawing station a heating station a first and second sealing station and a first and second stamping station.

Granted: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE     A battery charger(10)includes a capacitor(20)which establishes a level of current sufficient to fast charge in one-hour a battery(18)having from one to twenty cells.  An SCR(16)is controlled by a timer(42)to initially delay the supply of current while determining whether the battery(18)is hot or cool.  If battery(18) is cool, charger(10)proceeds to fast charge the battery.  After battery(18)is fully charged, the battery heats to a temperature where a NTC thermistor (58)responds to trigger a second timer(52)which controls SCR(16)to stop the fast charging operation.  Charger(10) is then controlled to prevent the charger from thereafter re-entering a fast charge mode.    If battery(18)is initially hot, charger(10)is controlled to further delay the initiation of a fast charge operation until the battery cools to or below the charge-start temperature.    A second NTC thermistor(90)is provided to compensate for the potential effect on the operation of thermistor(58)in response to temperature levels emanating from any environment other than from battery (18).

Abstract: ABSTRACT            A device stores a plurality of dishes or the like in a plurality of stacks, with each stack at an object-receiving region within the device.  The device includes a base and a plurality of spaced apart partitions for partitioning the space extending above the base into a plurality of object-receiving regions.  The space between the partitions forms a pair of diametrically opposite slits in each object-receiving regions.  In one embodiment, four generally T-shaped partitions together form four object-receiving regions, and a central open region.  In another embodiment, eight partitions, including two corner partitions, four generally T-shaped partitions, and two cross-shaped partitions, form nine object-receiving regions, one of which is a central open region extending above the center of the base.  The use of diametrically opposed slits facilitates the loading and unloading of dishes and permits the slits to be relatively narrow so that they occupy a relatively small proportion, about 23% in one embodiment, of the total lateral periphery of the object-receiving regions.  Further, the use of an object-receiving region positioned in the center of the device permits the formation of nine object-receiving regions, thereby increasing the number of stacks of dishes that can be stored in the device.   2$08Z/by
