Abstract: INVENTOR:  KLAUS MUNZEL          INVENTION: METHOD OF, AND APPARATUS FOR, DETONATING A            PROJECTILE IN THE PROXIMITY OF A TARGET             ABSTRACT OF THE DISCLOSURE           Upon detonating a projectile in the proximity of a target,  there are produced projectile fragments which fly towards the target in a predetermined direction.  To have as many  fragments as possible  fly towards the target,  the projectile must be detonated at a suitably selected angle measured between the line of sight which extends between the projectile  and  the  target,  and  the  projectile  flight trajectory.  This detonation angle varies as a function of the encountering velocity of the projectile and the target.  A predetermined reference value associated with a predetermined encountering velocity value is computed using a stationary firing control system and represented by the quotient    , wherein c is the velocity of light and VBg is the predetermined encountering velocity value.  Such reference value is stored in a storage device aboard the projectile.  The projectile also contains a device for determining a plurality of encountering velocity values and such device converts the determined encountering velocity values into actual values    , wherein c is the velocity of light and VB the measured encountering velocity value.  A comparator is connected with the determining device and storage device and compares the actual values and the reference value.  Detonation of the projectile occurs once the actual value is substantially equal to or exceeds the stored reference value.          WWK:(01):rmw:mnc15

Title: Memory element
Inventor: MCCOY WILLIAM C
IPC: B23K1/00
Filed: 1988-09-29
Granted: 1992-08-18
Abstract: Abstract of the Disclosure A memory element made of a shape-memory alloy includes lead-attachment and shape-memory portions and a partition interconnecting such portions.  The lead-attachment and shape-memory portions are comprised of characteristic internal structures, while the partition is comprised of an internal structure dissimilar to the characteristic internal structure of at least one of the lead-attachment and shape-memory portions.  Shape-memory effect characteristics of the shape-memory portion are preserved to maintain the memory function of the memory element by configuring the dissimilar internal structure to block transmigration from the lead-attachment to the shape-memory portions of selected contaminant material existing in the lead-attachment portion.  The partition functions as a contaminant filter to control the concentration of contaminant material in the shape-memory portion, thereby enhancing the durability of the memory element. A method is disclosed of altering the first crystalline structure of an uncontaminated memory element to provide the dissimilar, contaminant migration-blocking, internal structure.

Abstract: ABSTRACT        A rate controllable damping mechanism (10) is disclosed.  The mechanism includes a chamber disposed within a housing (15); an element (11) mounted for movement within the chamber; a damping material (13), preferably a low melting temperature metal alloy, in the chamber for preventing the movement of the element at a first temperature and for damping the movement of the element at a second temperature; and a heater (21) for selectively increasing the temperature of the damping material from the first temperature to the second temperature.   Controlled damping is effectuated by heating the fluid material until it reaches a molten state at which the resultant fluid damps the movement of the element in a conventional manner.  A novel method is also disclosed for structural stress relief.

Abstract: ABSTRACT         A Loran-C communications technique and system are disclosed involving appropriate encoding of communication messages and logical multiplication and inversion of encoded signals prior to phase modulation of the Loran-C pulses, with novel bit-flip connections for producing complementary plus and minus modulation position shifts in the first and third and second and fourth, etc., of the Loran-C pulse groups, and with perfect balance irrespective of the nature of the raw data and irrespective of skywave interference.  The invention also embraces a method of obviating errors in navigation locking caused by sampling reception at the conventional symmetrical pulse modulation time intervals in advance of and in delay from the normal transmission interval, through rendering the pulse modulation asymmetrical to a degree that compensates for different cycle amplitudes at sampling points above and below the desired sixth zero crossing used for navigation position determination.

Abstract: Abstract of the Disclosure Apparatus and method for analyzing a bit stream to determine whether the stream is encoded in A-law PCM or µ-law PCM.  Bit positions 2, 3, and 4 are examined to determine which of the 8 possible segment codes are present.  Segment codes representing low amplitude speech should predominate statistically over segment codes representing high amplitude speech.  If the sample cannot be classified by the appearance of low amplitude segments, the higher amplitude segments are compared and that coding law is detected as being present which accrues the lower count for such high amplitude segments.           .,

Title: Condiment dispenser
Inventor: WEIMER RALPH
IPC: B67D1/00
Filed: 1989-06-21
Granted: 1991-12-24
Abstract: ABSTRACT           A condiment dispenser is provided having a length of resilient elastic tubing with an upper tube section and a lower tube section.  An arm is pivotally mounted adjacent the tubing and moveable through dispensing and return strokes.  The arm has an upper arm portion adjacent the upper tube section and a lower arm portion adjacent the lower tube section.  During the dispensing stroke, the upper arm portion moves to compress the upper tube section against a wall on the opposite side of the tubing while the lower arm position retracts from the lower tube section to cause the condiment to be dispensed.  The return stroke is caused by the return of the compressed upper tube section to a less compressed section, causing the lower arm section to com-press and close the tubing at the lower tube section against the wall.
