IPC: G06F9/44
Filed: 1989-04-14
Granted: 1996-05-10
Abstract: A multi-bus microcomputer system includes a cache subsystem and an arbitration supervisor. A CPU is provided with a PREEMPT signal source which generates a preempt signal in CPU cycles extending beyond a specified duration. The preempt signal is effective at any device having access to the bus to initiate an orderly termination of the bus usage. When that device signals its termination of bus usage, the arbitration supervisor changes the state of an ARB/GRANT conductor, which had been in the grant phase, to the arbitration phase. During the arbitration phase each of the devices (other than the CPU) cooperates in an arbitration mechanism for bus usage during the next grant phase. On the other hand, the CPU, having asserted preempt, responds to a signal indicating initiation of the arbitration phase by immediately accessing the system bus.

Abstract: Disclosed is a plasma torch in which the position of the center electrode (1) is adjustable relative to the orifice of the plasma torch (2). The invention is based on a construction in which the center electrode (1) is mounted to the body part (9) of the plasma torch by way of a pivotal ball joint (7, 23), whereby the electrode (1) can be pivotally rotated in said joint (7, 23), thus making it possible to align the electrode tip to the orifice center of the plasma nozzle (2). The spherical element (7) of the pivotal joint is attached to the bearing box (23) with the help of a tightening gland nut (11, 12). The depth of the center electrode (1) can be adjusted by rotating a depth adjustment gland nut (14), which is attached to the spherical element (7) by a threaded joint. Due to its versatile adjustability, the function of the plasma torch can be maintained in a stable range, thus significantly contributing to reduced wear and damage of the plasma nozzles. <IMAGE>

Abstract: The compression of successive blocks of digital data is optimized by selecting between different compression algorithms or different data formats on a block-by-block basis. In one application, digitized interlaced video signals are processed for transmission in a compressed form. A set of pixel data presented in a field format is compressed to provide a first compressed video signal. The set of pixel data is also presented in a frame format and compressed to provide a second compressed video signal. Errors are evaluated in the first and second compressed video signals. The compressed video signal having the least error is selected for further processing. The technique is repeated for successive sets of pixel data and the selected signals are encoded to identify them as field formatted or frame formatted signals. The encoded selected signals are then combined to provide a compressed video signal data stream for transmission. Apparatus for receiving and decoding the signals is also disclosed. <IMAGE>

Title: Delay train ignition buffer
Inventor: DUFRANE RONALD M
IPC: F42B3/16
Filed: 1991-01-28
Granted: 1995-09-19
Abstract: A delay train ignition buffer (45) is positioned between a transmission tube (11) and a delay train (25) in a detonator housing (15) or a signal transmission tube housing.  The buffer controls the rate at which the transmission tube temperature/pressure pulse is applied to the delay train pyrotechnic surface, attenuating the effects of the pulse with a resulting improvement in delay timing precision.  The buffer also attenuates the effects of sudden depressurization within the detonator resulting from the rupture of the transmission tube or ejection of the tube from the housing, thereby preventing separation of the reacting pyrotechnic which could otherwise cause the reaction to cease at the point of separation, thus causing failure of the delay train to continue combustion of the pyrotechnic through its length.

Abstract: A shoe and shoe sole for accommodating forefoot strike activities such as aerobics, and forefoot strike tendencies of runners and the like, to forestall stress features, tendonitis and muscle tears, by incorporating a special forefoot pad in the midsole.  The pad has a forward chamber and a rearward chamber, separated by an internal wall with restricted orifices therein, the forward chamber being larger and extending curvilinearly beneath the five metatarsal heads of the foot, and the rearward chamber being smaller and extending behind the second, third and fourth metatarsal heads in the arch region of the foot. Impact compression by the metatarsal heads on the forward chamber causes controlled viscous liquid flow into the rearward chamber to absorb impact force, and such that the amount of liquid in the rearward chamber is temporarily greater than its at rest volume, causing the walls of that chamber to bulge and form a temporary arch support.  Release of force on the forward chamber results in the resilient flexible bulging walls of the rearward chamber forcing liquid back to the forward chamber.

Title: External security module for a television signal decoder
Inventor: GAMMIE KEITH BEVERLY
IPC: H04N7/167
Filed: 1991-01-30
Granted: 2001-03-27
Abstract: A decoder for descrambling encoded satellite transmissions comprises an internal security element (1019) and a replaceable security module (1014). The program signal (SYS) is scrambled with a key (KOMI) and then the key itself is twice-encrypted and multiplexed with the scrambled program signal. The key (KOMl) is first encrypted with a first secrete serial number (SSN1) which is assigned to a given replaceable security module (1014). The key is then encrypted with a second secret serial number (SSN0) which is assigned to a given internal security element (1019). The internal security element (1019) performs a first key decryption using the second secret serial number (SSN0) stored within the internal security element (1019). The partially decrypted key (E SSN1(KOM1)) is then further decrypted by the replaceable security module (1014) using the first secret serial number (SSN1) stored within the replaceable security module (1014). The decoder then descrambles the program using the twice-decrypted key (KOM1). The replaceable security module (1014) can be replaced, allowing the security system to be upgraded or changed following a system breach.

Title: Snow blower augers and impellers
Inventor: MAXFIELD LEROY
IPC: E01H5/09

Granted: 1995-06-20
Abstract: An auger type snow blower assembly having an auger with two sets of rotating ribbon spokes which transfer snow from the auger to an impeller inlet located at the mid-portion of the auger assembly, the ribbon spokes terminating a substantial distance short of the center of the auger assembly whereby snow lying directly in the center of the path of the auger assembly may move directly to the impeller inlet without contact with the ribbons. Further, the ribbons revolve around a generally cone-shaped structure at the ends of the auger assembly whereby the ribbons and the stationary cones cooperate to impel snow entering the auger assembly toward the impeller inlet.  The auger assembly further includes a bi-directional, variable speed hydraulic drive system for the ribbon system consisting of variable forward speeds and reverse speeds, the forward speeds including a low ribbon speed high torque speed, and a high ribbon speed low torque speed, together with pressure relief valves to avoid the use of shear pins.  The impeller is lined with UHMW polyethylene plastic to provide very low friction between the snow and the components of the impeller which come in contact with the snow.
