Abstract: RCA 79,356 ABSTRACT OF THE DISCLOSURE A circuit for use in a video display apparatus corrects raster shift due to beam current variations.  A horizontal retrace related pulse is applied to the ramp generator for the horizontal deflection phase control circuit, causing the retrace AC zero crossing of the ramp to shift under high beam current conditions.  The phase control circuit then shifts the ramp signal to center the synchronizing  pulses about the zero crossing, resulting in a raster shift which compensates for the raster shift introduced due to beam current variations.

Abstract: Abstract Direct Use of Methanol Fuel in a Molten Carbonate Fuel Cell A method of powering a high temperature molten carbonate fuel cell using direct internal reformation of methanol.  The methanol is reformed spontaneously using the anode catalyst and cell waste heat creating hydrogen which is consumed as fuel at the anode and carbon dioxide which is used to enrich the cathode oxidant.  In addition, the reformation reaction is endothermic and therefore will aid in managing excess heat at the anode.

Abstract: ABSTRACT OF THE DISCLOSURE         A device and garment for use by small animals of both sexes to absorb and collect body waste fluids is disclosed.  The device includes an outer garment which has a waist aperture for fitting around the body of a small animal, a pair of leg apertures for fitting around the legs of the animal, and a tail aperture.  The waist aperture and the leg apertures include a resilient material or band for assuring that the apertures fit snugly around the animal's body and legs respectively.          The tail aperture is particularly located and of such a size that the anal opening of the animal is not covered.  The outer garment further includes a first portion of an attaching means such as a snap or "Velcro" fastener at a first location which is adjacent the tail aperture and in between the leg apertures.  Also included is another first portion of an attaching means located adjacent the waist aperture.  A disposable pad is fitted within the outer garment as an absorbent layer and a liquid impervious layer.  A second portion of an attaching means which cooperates with either of the first portions on the garment is used to hold the disposable pad in a first location.  When placed in the first position, an attaching edge is adjacent the tail aperture, and a free edge is directed toward the waist aperture.  In this position, the garment and disposable pad are particularly suitable for collecting the urine and esters discharge of a female animal.  Alternatively, the disposable pad may be located with the second portion of the attaching means connected to the second first portion such that the free edge is directed towards the tail aperture and the attaching edge is adjacent the waist aperture.  In this position, the outer garment and disposable pad are particularly suitable for collecting and absorbing the urine discharge of a male animal.

Abstract: ABSTRACT OF THE DISCLOSURE     A disk drive is provided with a vent tube which is long (e.g., 20 inches) compared to its bore (e.g., 0.013 inch) to minimize diffusion of water vapor into the drive without seriously affecting pressure gradients along the length.  Minimum bore diameters are given for specified lengths of vent tube.  Conveniently, a desiccant is employed with a heater to absorb water vapor admitted to the drive and to expel water vapor when the drive is operated. A thermally-operated valve is also employed to expel water vapor when the drive operates.  The desiccant may be employed in a chamber separated from the disk chamber, whereupon pressure valves are provided to adjust the pressures in the drive.

Abstract: ABSTRACT         A  safety  flow  control device for use in  a  beverage distribution  system  of the character using pressurized  gas  to dispense  the beverage from its containers for ensuring that  the containers  are not accidentally overpressurized.   The device of the invention is adapted to be placed in the line which  connects the  pressure  source to the containers for  the  beverage.   The device embodies a rupture disc having a first side exposed to the gas used in pressurizing the containers and a second side exposed to  atmosphere.   Strategically  positioned between the  pressure inlet of the device and the pressure side of the rupture disc  is a  valving mechanism which is maintained in an open configuration by  the  rupture disc.   In the open  configuration  the  valving mechanism  permits  the gas to flow from the inlet into  a  first sub-chamber  defined  by the first side of the rupture  disc  and then  outwardly through the outlet of the device.   When the rup-ture  disc fails,  the valve mechanism will  automatically  close preventing  further  flow of gas into the first  sub-chamber  and toward  the  outlet.   The valve is constructed so that  it  will remain  closed  until pressure on the inlet side of the  unit  is relieved.

Abstract: ELECTROSURGICAL GENERATOR WITH HIGH-FREQUEMCY  PULSE WIDTH MODULATED FEEDBACK POWER CONTROL     Abstract of the Disclosure A pulse width modulation technique regulates the output power of each cycle of a radio frequency surgical signal of an electrosurgical generator.  The delivered power of the surgical signal is determined by multiplying the sensed current and the sensed voltage of the surgical signal.  An error signal is established by the difference of the actual delivered power with respect to a selected desired output power.  The error signal is operatively utilized to modulate the pulse width of each driving pulse which creates the cycles of the surgical signals.  Limits on he sensed voltage and sensed current signals are established to limit the output characteristics of the surgical signal.  A minimum current limit signal is utilized to limit the maximum output voltage into relatively high impedances.  A minimum voltage limit signal is utilized to limit the maximum output current into relatively low impedances.  Very rapid response times and very effective power regulation even into relatively high impedance tissues are possible with the pulse width modulation technique.  The risks and problems associated with open circuit flashing, alternate path burns and closed circuit shorting are substantially reduced or eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE A glass scratch removal apparatus includes a driven rotating tool that is supported on a skirt that can be sealed against a surface to be treated for scratch removal.  The skirt is conical and has some flexibility to permit the edge of the skirt in contact with the surface to deform in shape to follow curves or irregularities (such as on a curved windshield of an automobile) and at the same time, the skirt is held in place through the use of a vacuum.  The rotating tool is pressed against the surface to lap and polish the surface.  The tool is manually actuable toward and away from the surface, and a slurry is fed into the skirt to provide either for "fining" which is an initial step of rough removal of material adjacent the scratch and/or "polishing" which blends in or feathers the surface adjacent the scratch and provides for an optically satisfactory surface.  The amount of pressure on the tool can easily be controlled at the same time that the tool is being moved across the scratch, so that the tools can be lowered gradually against the surface to be worked on to avoid gouges or burnished spots or the like.

Abstract: APPARATUS AND METHOD FOR DISPLAYING  HOLE-ELECTRON PAIR DISTRIBUTIONS  INDUCED BY ELECTRON BOMBARDMENT                     ABSTRACT          An improved electron bombardment induced conductivity apparatus and method is described for charge collection imaging of semiconductor materials and devices with unprecedented resolution.  This is accomplished by bombarding a very small area of the surface of a specimen with low-energy electrons rather than high-energy electrons and by physically scanning (i.e. moving) the electron source itself (rather than only the beam of electrons) with respect to the specimen.  A very small area of the specimen surface is bombarded with low-energy electrons without any need to do focussing by emitting the low-energy electrons from a sharply pointed electrode positioned very close to the surface being bombarded with the low-energy electrons.            While the pointed electrode is scanned over (and preferably at an essentially constant distance from) the surface of the specimen to be investigated, hole-electron pairs created by the electron bombardment are sensed (preferably collected by an electric field) and a measurement of the sensed number of such hole-electron pairs is displayed in synchronism with the electrode scanning to produce a charge collection image of the specimen, revealing structural or other characteristics thereof.  The distance between the pointed electrode and specimen surface, as well as the diameter of the electrode tip, is preferably between 0.1 and 10 nanometers, and the voltage between the pointed electrode and the specimen surface is preferably between 1 and 10 volts.
