Title: Improved vehicle tire deflator
Inventor: KILGROW DONALD C
IPC: E01F13/12
Filed: 1993-02-25
Abstract: An improved vehicle tire deflator that is a foldable and can be deployed by pushing it or pulling it to an extended attitude across at least one full traffic lane, and includes a number of rocker arms that are pivotally coupled to base supports to form a frame that is collapsible and when extended, includes a stop arrangement for holding the rocker arms apart. Which rocker arms each include a plurality of actuators and spaced spike base bosses, with each spike boss center holed and countersunk to accommodate an end of a hollow spike and attached resilient grommet fitted therein. With a tire rolling onto which rocker arm actuator, the rocker arm is canted towards the rolling tire tread surface, pointing a hollow spike sharp end at that tire tread to pierce and lodge therein as the tire rolls over it, and with continued tire rolling the hollow spike is pulled from its spike base boss seat and travels fully into which tire, allowing air from within that tire to vent to atmosphere. Alternatively, for penetrating a steel belted tire, or the like, an insert formed of a hard steel, or the like, and having a pointed end is fitted longitudinally into and maintained in which hollow spike without blocking the air passage through which hollow spike, the insert pointed end extending beyond the hollow spike pointed end to first contact the tread of a tire rolling thereover. The resilient grommet absorbs forces as are exerted by the tire rolling over the hollow spike pointed end that would otherwise distort and deform the sides of the spike base boss seat, thereby maintaining the shape of which seat to allow for the replacement of hollow spikes, with or without inserts, fitted therein, providing for deflator reuse.

Title: Transfer mechanism for magnetic tape cartridges
Inventor: PIERRAT MICHEL A
IPC: G11B15/68
Filed: 1993-05-03
Abstract: ABSTRACT OF THE DISCLOSURE In a mechanism for transporting a tape cartridge or cassette, a gripper arm carries two spaced projections that engage one surface of the cartridge. A gripper finger, formed of material with sufficient flexibility that any accidental external forces applied to the cartridge will result in release of the cartridge without damage to the case, engages the opposite surface of the cartridge, between the two projections. The gripper finger itself moves first in a rotary path to position the gripper finger adjacent one edge of the cartridge and secondly is translated in a direction perpendicular to the surface of the cartridge to be clamped.      The rotary movement of the gripper finger is produced by rotary movement of a flexural beam while the translation is produced by a collar having a cam that impinges on a smooth surface to deflect the collar and move the gripper finger upwardly to secure the cartridge. The toggle action of the cam eliminates the need for continued external forces to maintain the cartridge in clamped condition. A lost-motion arrangement permits limited rotation of the flexural beam to move the gripper finger into and out of engagement with the cartridge surface without causing any translation of the gripper finger.

Title: Methods and apparatus for creating a gelatin coating
Inventor: BERTA NORBERT I
IPC: B05C3/09
Filed: 1994-01-11
Abstract: These and other objects of the present invention are achieved by an apparatus for coating product with two colors which includes a first coating section, a second coating section and a means for transferring products from the first to the second sections. The first section includes a feeding and loading station for depositing products onto product holders retained in product carrier plates. The products are advanced to a first dipping station in which a vacuum chamber having the plurality of vacuum tubes engages a plate and inverts and dips the products to coat a first portion of the product. The plates are then advanced to a first rotating station where another vacuum chamber and vacuum tube device engages the plates and rotates the plates one revolution for spreading the coating over that first portion. The plates are advanced to an elevator where they are raised incrementally to a dryer that extends over the first section of the coating apparatus. The plates are transferred into the dryer where they traverse through the dryer in a controlled manner for curing the coating applied to the first portion. The plates are transferred to a down elevator and returned to the conveyor where they are advanced to a side to side transfer apparatus. The transfer apparatus transfers the products to the second section of the coating apparatus in such a manner to expose on carrier plates the uncoated portion of the products. The plates are then advanced to identical dipping and rotating stations as in the first section and then transferred by an elevator up to a second dryer located above the conveyor in the second section. The plates traverse the second dryer and are returned to the second conveyor by a down elevator where the plates are advanced to an unloading and discharge apparatus. the empty plates are then advanced to the side to side transfer where they are recycled for future use in the apparatus.

Title: Reservation overriding normal prioritization of microprocessors in multiprocessing computer systems
Inventor: MELO MARIA L
IPC: G06F15/16
Filed: 1993-09-29
Abstract: RESERVATION OVERRIDING NORMAL PRIORITIZATION OF MICROPROCESSORS IN   MULTIPROCESSING COMPUTER SYSTEMS              ABSTRACT Three prioritization schemes for determining which of several CPUs receives priority to become bus master of a host bus in a multiprocessor system, and an arbitration scheme for transferring control from one bus master to another.  Each prioritization scheme prioritizes n elements, where a total of (n/2)x(n-1) priority bits monitors the relative priority between each pair of elements.  An element receives the highest priority when each of the n-1 priority bits associated with that element points to it.  In the arbitration scheme, the current bus master of the host bus determines when transfer of control of the host bus occurs as governed by one of the prioritization schemes.  The arbitration scheme gives EISA bus masters, RAM refresh and DMA greater priority than CPUs acting as bus masters, and allows a temporary bus master to interrupt the current bus master to perform a write-back cache intervention cycle.  The arbitration scheme also supports address pipelining, bursting, split transactions and reservations of CPUs aborted when attempting a locked cycle.  Address pipelining allows the next bus master to assert its address and status signals before the beginning of the data transfer phase of the next bus master.  Split transactions allows a CPU posting a read to the EISA bus to arbitrate the host bus to another device without re-arbitrating for the host bus to retrieve the data. The data is asserted on the host bus when it is idle even if the host bus is being controlled by another device.
