Abstract: A B S T R A C T         A squeeze bottle contains a dry funnel cake mix, an opening and a selectively removable and replaceable cover for the opening.   A funnel integral with the cover extends from the remainder of the bottle. With the cover removed from the opening, water is poured through the opening.  The liquid and mix in the bottle are mixed by shaking the bottle to form a funnel cake batter while the cover and funnel are closed so the contents of the bottle can not escape during mixing.  Then, while the funnel is open, the batter is dispensed through the funnel into a cooking vessel having heated cooking oil therein.  The batter is dis-pensed by holding the bottle so an open end of the funnel remote from the remainder of the bottle is in a generally downward direction while the bottle is squeezed to exert pressure on the batter.  A cap for the open end of the funnel is placed on the funnel open end to close the funnel after the batter has been dispensed to enable remaining batter in the bottle to be stored.

Abstract: Abstract of the Disclosure An apparatus and method of providing vertical smoothing of convergence correction signals in a digital convergence system is disclosed. The surface of a cath-ode ray tube is subdivided into a matrix including a plurality of intersecting rows and columns and having a plurality of intersections corresponding thereto. A value is assigned to each intersection of a row and a column of said matrix. An electron beam traces a plu-rality of scan lines within each of the rows of the matrix. For each scan line within a row of the matrix, a convergence correction signal is synthesized using the plurality of values associated with the plurality of intersections in said row. A plurality of horizontal discontinuities are present in the convergence correc-tion signal as a result of the different magnitudes asso-ciated with the plurality of values used to synthesize the convergence correction signal. Using conventional filtering techniques, the impact of the horizontal dis-continuities in the convergence correction signal may be minimized thereby providing horizontal smoothing of the convergence correction signal. When the electron beam begins tracing the plurality of scan lines in the next, subsequent row of the matrix, a vertical discontinuity is produced, i.e., a gap or an overlap between groups of scan lines traced by the electron beam. The impact of these vertical discontinuities can be minimized by pro-viding vertical smoothing of the convergence correction signal. This vertical smoothing is accomplished by using a linear interpolator to interpolate between values asso-ciated with two adjacent, vertically oriented intersec-tions of said matrix, and by progressively changing the magnitude of the convergence correction signal in re-sponse thereto. Vertical smoothing of the convergence correction signal is accomplished and the vertical dis-continuities between groups of scan lines traced by the electron beams are eliminated.

Abstract: ABSTRACT     A flameless  nitrogen  liquid  to gas  converter  for providing high pressure nitrogen gas to treat oil and gas wells.  A diesel engine prime mover drives hydraulic pumps and motors to pressurize nitrogen and actuate a closed-loop water system and a series of heat exchang-ers.   The closed-loop water system provides heat  for converting the liquid nitrogen to gaseous nitrogen which is obtained from the engine jacket water,  the engine exhaust and the hydraulic oil from the hydraulic pumps and motors.   Additional heat can be obtained from the hydraulic oil system by increasing the hydraulic system pressure with an hydraulic pressure control valve.   At least one of the hydraulic pumps and its driven hydrau-lic motor  is  in  an  hydraulic  circuit  which  includes variable  means  for  increasing  the  pressure  in  the hydraulic circuit,  hydraulic oil-water heat  exchanger and an hydraulic oil reservoir.   Hydraulic fluid from the other pumps and motors is transmitted through the hydraulic oil-water heat exchanger.  The system includes a  closed-loop  water  heat  exchange  system  having  in series in the water flow line upstream to downstream the following components  in  the  following order:   engine water - water heat exchanger, hydraulic oil - water heat exchanger, engine exhaust - water heat exchanger, nitro-gen - water heat exchanger, and a centrifugal water pump capable of 100 gallons per minute at 60 psi.

Abstract: ABSTRACT TOUCH SENSITIVE DEVICE There is disclosed a tactile sensor comprised of a compliant overlay having a surface of spatially dispersed semi-spherical domes in registration with sequentially pulsed signal means, such as light emitting diodes.  The domes adaptively collapse upon the application of pressure applied to the opposite surface of the overlay entrapping signals by relection between the overlay surfaces.  The entrapped signals migrate by reflection to the edges of the overlay for reception by photodetectors.  The output from the photodetectors is then processed for determining the magnitude, location and profile of the pressure applied across the overlay.  A feedback arrangement is also provided for controlling the magnitude of the externally applied pressure.     DSW/KW.

Abstract: TWO-PULSE TACHYCARDIA CONTROL PACER     Abstract of the Disclosure There is disclosed an improved pacer for con trolling tachycardia.  Prior art pacers of this type generate a stimulus a short time, known as the "initial delay", after confirmation of tachycardia.  The initial delay is "scanned" from one extreme to the other until the condition is terminated  In some pacers of this type, a second stimulus is generated at a fixed time, known as the "coupled interval", after the first stimulus; the second stimulus sometimes terminates the condition even if the first does not.  In the improved pacer, the coupled interval is scanned as well as the initial delay.          Also, the time parameters which are successful in ter-minating the condition are stored so that upon confirmation of another tachycardia event, the previously successful time parameters are the first ones to be tried.  The unit also allows tachycardia to be induced by the physician so that the parameters which are programmable can be ad-justed for optimum performance following a subsequent naturally occurring tachycardia confirmation.

Abstract: A B S T R A C T            When sanding e.g. panel doors (12) in a machine, the doors are placed under six horizontal sanding spind-les (10) with sanding members (11) which partly rotate and partly are moved around a vertical driv-ing cylinder (19). The spindles (10) are mounted in such a way that they can be programmed to rotate in a given direction and in necessary be completely disengaged. This programming is done by placing cams (17, 18 and 23, 24) for engaging and disengaging the spindle (10) by vertical movement of a friction cone (8) on the spindle between an upper and a lower friction path (6, 7) on the side of the driving cylinder (19).     Hereby a perfect sanding is obtained as the doors (12) are engaged by the sanding threads from many different sides thus eliminating sanding traces.          Furthermore, the machine can be adjusted to the shape of the work piece, whereby it is possible to adapt the sanding operation individually according to the work piece and also to stop the sanding e.g. when the sanding members move across sharp edges on the work piece, said edges therefore remaining quite sharp as they are not exposed to any sanding.

Abstract: ABSTRACT A method of determining image input contrast to dynamically adjust screen amplitude. The screen amplitude is controlled on a dot by dot basis to selectively enhance the original image. There is a higher amplitude when the input contrast is low and a lower amplitude when the input contrast is high. Thus, the partial dots more closely follow image detail at high contrast, while at low contrasts, noise is not enhanced. In a specific embodiment, depending upon the input contrast, a predetermined screen amplitude is used.
