Abstract: WIDE DYNAMIC RANGE SHIFT SPEED SENSOR               ABSTRACT OF THE DISCLOSURE         A digital shaft speed sensor modifies a clock frequency and counting period to provide a speed signal having wide dynamic range with adequate resolution.  The division ratio of a programmable divider counting pulses from a shaft encoder is modified by a central processing unit based on the count or speed measured in a preceding counting.          The output of the programmable divider sets an interval during which clock pulses are counted to determine the shaft speed.  Since the dividing ratio of the programmable divider is dynamically changed according to previous speed measurements, the total number of clock pulses is correspondingly changed.  In addition, the output frequency of the clock pulses is changed so that, at low speed, a low clock frequency can be used and at higher speeds, one or more higher clock frequencies can be used to maintain resolution with register memory

Abstract: Abstract of the Disclosure The invention is intended to cool integrated circuit packages carried on substrates.  As is known, to achieve such cooling, the substrates are mounted to a cold plate via a compliant mat acting as interface.  In the invention the mat comprises a paste film in contact with the cold plate, a metallic film in contact with the paste and a third film in contact with the metallic film.  Both the paste and the third film are heat conductive and electrically insulative.  The metallic film acts to spread the heat generated by the circuit packages more uniformly.  To render the mat more compliant the metallic film is etched to remove portions leaving an array of contact pads in respective alignment with the circuit packages.  The contact pads of the array may be interconnected by unetched branch portions of the metallic film to spread the heat flux.

Abstract: METHOD AND APPARATUS FOR FORMING AND REFORMING A FURROW  Abstract of the Disclosure To form a furrow for row guidance systems, a shank is mounted on a frame forwardly of a wheel which includes a V-shaped tire.  The shank opens the ground and the tire crushes clods and packs the sides of the furrow.  Depth bands on each side of the tire shape the edges of the furrow and prevent loose dirt from rolling back into the furrow.  When utilized to reform a furrow, the frame is pivotally connected to the implement for rocking about an upright axis to allow the wheel to trail and average out guidance system corrections and driver steering corrections so that the reformed furrow will be more accurate for the next operation.

Abstract: ABSTRACT          Faced with the necessity to establish a mechanical connection between the components of a supporting structure a great many techniques and devices have been developed. This invention adds to the existing repertory a joint where a plurality of elong-ated members, positioned in a circular configuration, is held together by a link which embraces them all at once, thus elim-inating the need for seperate fastening devices on each and every single member. The elongated members protrude from the joint at predetermined angles protecting towards adjacent joints in a predetermined distance, thereby defining in shape and size entire structures. The joints may be secured against rotation and shifting, individually by means of pins or keys, or collectively by fitting trigonal, tetragonal or pentagonal panels between a corresponding number of joints.

Abstract: ABSTRACT A gas mixture containing phosphine and R1R2R3 In x R4R5R6 or R1R2 In x R4R5 where the Rs are alkyl groups is passed over a semiconductor substrate comprising indium and phosphorus so as to deposit a semiconductor material comprising indium and phosphorus, and the exposure of the substrate to phosphine is controlled to avoid or reduce transport of the substrate material.      Thus, for example, indium phosphide may be grown onto corrugations in gallium indium arsenide phosphide, the corrugations being undeformed during this growth. Such a growth step may be used in the production of distributed feedback semiconductor lasers operating near 1.55 nm

Abstract: ABSTRACT OF THE DISCLOSURE      The disclosure is directed to an apparatus and method for obtaining an improved moire fringe pattern image of an object.  A beam of incoherent light is projected at the object.  A grating is disposed in the path of the beam projected at the object, this grating being referred to as a projection grating.  Means are provided for focusing the beam reflected from the object to obtain an image at an image plane.  Another movable grating is disposed at the image plane.  This movable grating is referred to as a reference grating.  Means are provided for recording the image at the image plane, the recording means being, for example, a photographic or video camera. In accordance with an important feature of the invention, means are provided for moving the projection grating and the reference grating in synchronism.  In a preferred embodiment, the projection and reference gratings are mounted in spaced relation in a movable member, and the synchronized motion of the gratings is implemented by moving the member.  In a form of the disclosure, a double-projection set-up is used wherein two projection beams are directed at the object through first and second movable projection gratings, respectively.  In this embodiment, the first and second projection gratings are moved in synchronism with the reference grating.  This is preferably achieved by mounting the three gratings in appropriate spaced relationship in a common member, and moving the member.

Abstract: ABSTRACT USER AUTHENTICATION SYSTEM          Disclosed is a system which employs a pair of encryption functions f and g in the "log on" protocol of a computer dial-up arrangement. The functions are inverses of each other and, hence, a random sequence when encrypted with f and then with g results in the original sequence. When a user wishes to "log on" the computer selects a random sequence and forms a challenge sequence.  The user encrypts the challenge sequence with the function g and thus forms a response sequence.  Encryption with the function f by the computer permits verification of the response sequence.           The secrecy of the user's function is maintained by providing the user with an authenticating device having only two ports:  a power port and an I/O port. The I/O port is connected to a microprocessor which accesses a memory that contains the secret encryption function g.

Abstract: FIRING MECHANISM FOR HIGH RATE OF    FIRE REVOLVING BATTERY GUN ABSTRACT OF THE DISCLOSURE A gatling type gun has a plurality of gun bolts in an annular row on a rotor in the gun housing. A firing pin control on the housing sequentially engages a cocking pin on each gun bolt as the rotor rotates the respective gun bolt past the firing position.  The firing pin control has two dispositions.  One disposition causes the forward tip of each of the firing pins to project where the respective cocking pin has been engaged, and another disposition causes the forward tip of each of the firing pins to be precluded from projecting.  The first disposition is achieved by coupling the kinetic energy of the rotor to the firing pin.  Thus, the firing pins cannot project when the rotor is not rotating.
