Title: Method for locating and purifying dna containing single base mismatches
Inventor: FORD JOHN P
IPC: C12Q1/68
Filed: 1986-08-27
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE            A method for distinguishing  fragments of  DNA which contain single base mismatches from their perfectly paired homologues is disclosed.   Single stranded regions within a duplex fragment are modified with carbodiimide, which reacts with unpaired guanine  (G)  and thymine  (T) residues in DNA.  Linear duplex DNA molecules do not react, while  DNA  molecule   with  single  base  mismatches  react quantitatively with carbodiimide.  Following reaction with carbodiimide,  the DNA molecules are fractionated on high percentage  polyacrylamide  gels  such  that  modified  and unmodified   fragments   can   be   clearly   distinguished.          Application of this technique in order to locate and purify DNA sequence differences responsible for phenotype variation and inherited disease is disclosed.

Title: Speed control circuit for mechanical scan ultrasonic imaging apparatus
Inventor: SHIRAISHI MASAAKI
IPC: G01S15/89
Filed: 1986-12-15
Granted: 1991-01-08
Abstract: "Speed Control Circuit for Mechanical Scan Ultrasonic Imaging Apparatus"                 ABSTRACT OF THE DISCLOSURE       In an ultrasonic imaging apparatus of the type having a plurality of selectable modes of operation, a motor-driven electroacoustic transducer is steered in a sector field in a predetermined relation to a selected operational mode.  The sector scan format of returning echos is converted to a line-by-line raster display format in response to line sync pulses.  The number of line sync pulses generated per unit time interval is scaled by a factor of N/M, so that it corresponds to the the number of pulses generated by the encoder during the same time interval, where N and M are integers which are variable as a function of the selected mode.  Phase comparison is made between the pulses generated by the encoder and the scaled line sync pulses to generate a phase difference signal from which a speed control signal is derived for controlling the speed of the motor.  Since phase comparison is made for all the pulses generated by the encoder, the resolution of motor speed control is increased with respect to the number of energy transmissions, eliminating blurred or distorted tomographic images.

Abstract: Abstract of the Disclosure Flame Incubating and Propagating Apparatus For A Fuel Combustion System Conventional direct-injection internal combustion engines having a fuel injector with multiple fuel spray orifices will not completely ignite and burn relatively lower-cetane-number alternative fuels such as 100 percent methanol or ethanol.  That is because the fuel spray injection pattern, per se, usually cannot carry or propagate a flame to all the injected fuel which is typically made up of individual fuel streams which are separated by sectors of fuel-deficient intake air.          The present fuel combustion system includes a multiple-orifice fuel injector, a baffle having a concave surface, and a fuel ignition-initiating device such as glow plug positioned generally in spaced relation between the fuel injector and the concave surface.  The baffle intercepts and temporarily maintains a stoichiometric preselected portion of at least one, and preferably two, fuel streams in ignitable proximity to the fuel ignition-initiating device to positively start a localized flame of burning fuel.  The baffle controlledly reflects and rapidly directs the resultant expanding flame of burning fuel to all of the remaining fuel streams so that they are interconnectedly bridged with the flame and thereby positively ignited.

Granted: 1991-04-23
Abstract: ABSTRACT OF THE DISCLOSURE       When a raising switch (21) or a lowering switch (23)  is operated in an electric blind apparatus, an NPU (34) rotates a geared motor (4)  so that a take-up drum (37) winds or unwinds a lifting tape (10) to raise/lower vanes (13) of a blind.  Upon rotation of the take-up drum, a photointerrupter (38) generates pulse signals and the MPU counts the pulse signals to judge a vertical position of the blind.  When an opening or closing switch (24, 26) is operated, the MPU rotates the geared motor so that a ladder drum  (39)  is rotated to wind ladder cords  (11) fixed to the ladder drum, thereby to adjust an open/close angle of the vanes.   Following rotation of the ladder drum,  a photointerrupter (41) supplies pulse signals to the MPU, which in turn counts the pulse signals to judge the open/close angle of the vanes.

Granted: 1993-05-25
Abstract: BALE PUSH BAR                   Abstract of the Disclosure A U-shaped bale push bar straddles a discharge gate of a large round baler with opposite legs of the bar being respectively pivotally connected to a pair of support brackets which are secured to and project rearwardly alongside the discharge gate from upper rear locations of opposite sidewall sections forming a portion of the baler main frame.  A pair of chains are coupled between forward locations of the gate and the legs of the push bar and serve as lost-motion connections that cause the push bar to extend and retract respectively in following relationship to opening and closing movements of the gate such that interference between the gate and a discharged bale is avoided.  An over center spring assembly acts between the push bar and support brackets to bias the bar toward its retracted position when the gate is closed and to bias the push bar toward its extended position when the gate moves a small amount towards its open position a small amount beyond an intermediate position permitting discharge of a bale.  A shock absorber assembly works against the energy of the over center spring assembly to prevent sudden motion of the push bar.

The stapling head cylinder, if the stapling heads are energized, staples the webs together, and transfers them to grippers (7) on the combination cylinder which, in turn, folds the stapled sheets by operation of the folding blades thereon in association with folding jaws of a folding jaw cylinder (15) located adjacent the combination cylinder.  The stapling head cylinder and the folding jaw cylinders are located, at least in part, laterally of the combination cylinder, so that the apparatus does not require substantial height.  The stapling heads can be selectively operated, so that unstapled copy products likewise can be handled.
