Inventor: ASHKIN PETER B
IPC: G06F13/00
Filed: 1990-04-12
Granted: 1992-01-21
Abstract: ABSTRACT OF THE INVENTION This invention discloses a method for requesting service by a device coupled to a host computer through a communication medium. The method comprises monitoring a command from the host computer, generating a service request signal on the medium after the command, and repeating the steps until the device receives a command which services the device. This is an efficient method for providing a means for peripheral devices to indicate a need for servicing to the host computer.

Abstract: A vibrating harrow with a supporting frame consisting of at least two beams that are positioned one behind another, extend across the direction of travel, and are equipped with soil-cultivation tines. The beams are mounted on the supporting frame by means of rockers and are moved back and forth across the direction of travel during operation through the intermediary of a drive mechanism by the power source of a tractor or cultivator. In order to provide a very simple and effective suspension for the cultivating tines parallel and at an angle to the direction of travel when obstacles are encountered in the soil, the beams are longitudinal beams with a U-shaped cross-section, the open side of each longitudinal beam faces away from the direction of travel, the rockers are mounted on the upper flank of the beams, the tines are mounted on the lower flank of the beams, and the beams are open at the rear over approximately their total length.

Abstract: A device for separating gas from liquid, in particular for separating air from water and for discharging the separated gas, is designed for placing in a liquid circulation system through which gas-containing liquid flows. The device comprises a housing with a feed aperture (4) and a discharge aperture (5) for the liquid to be degassed. The internal space of the housing is at least partially filled with open filling elements (7) which have a large surface area relative to the volume taken up. The filling elements (7) can be the shape of hollow cylindrical elements, known per se, comprising a cylindrical wall (8) provided with apertures, and projections (10) extending inwards from the wall. At the top side of the housing, in the wall thereof, a valve (17) for the discharge of the separated gas is provided. The valve is operated by a float (18) comprising a float element (19) and a float rod (20). The float (18) is guided in a freely movable manner in the axial direction by float rod guide elements (21, 24, 25), and is provided with a valve operating element (27) which in the non-working position lies clear of a valve opening element (35) connected to the valve (17), and for opening of the valve (17) can cooperate with said valve opening element (35).

Date Jul. 26, 1990.A fastening device in the form of a plug and a screw is adapted for installation in a blind bore of a thick wall or in a through hole in a thin wall. The plug is formed as an elongated body having a central longitudinal hole. The body has inner and outer end portions and two parallel slots extending longitudinally between the end portions to define four legs arranged circumferentially around the body. The legs diverge from the end portions to form an increasing diameter for the body which reaches a maximum at the center of the body. When the plug is inserted into a blind bore the legs are displaced inwardly to reduce the size of the central longitudinal hole so that when the screw is inserted into the plug, the screw will exert force on the legs to press the legs against the wall with strong radial forces. When the plug is inserted in a thin wall, threaded engagement between the screw and the inner end portion of the plug produces longitudinal displacement of the inner end portion and radial deformation of the legs to provide clamping pressure at the back of the wall at four distant locations.

Abstract: A paper-manufacturing machine and method include the feature of detaching a web from a forming wire by utilizing a stationary transfer suction box past which a felt travels while contacting the web so that the latter becomes detached from the forming wire and adheres to the felt while travelling with the latter beyond the forming wire. The felt and web are lapped through a substantial angle around a roll having a recessed surface whiletravelling toward the first press nip of a press section, and at this roll around which the felt and web are lapped a means is provided for directing steam toward the web and through the latter and the felt inwardly toward the recessed surface of the guide roll so that the flowing steam will on the one hand heat water carried by the web to enhance dewatering of the web at the first press nip while on the other hand the steam will serve to maintain the web reliably in engagement with the felt as the latter travels toward the first press nip. Beyond the first press nip the web may be subjected to one or more additional press nips and, if desired, to the smoothing action of a smooth-surfaced roll which presses the web against a central smooth-surfaced roll of the press section, before the web is guided away from the central press roll to a drying section.

Abstract: A method and apparatus for a microinstruction controlled unit having multiple subunits which are controlled by microoperations encoded within microinstructions from a control store. One master subunit controls the order in which the microinstructions are executed by generating the address of the next microinstruction to be read from the control store. The method provides for the overlapping of the execution of a current microinstruction while the next microinstruction is being addressed and read from the control store. The control store is divided into control substores with each control substore located near the subunit which executes the microoperations stored in its associated control substore. Subunits can affect the order of microinstruction execution by causing a trap in the master subunit which will cause the next microinstruction to be read from a predefined address within the control store. If required, the master subunit can read in status information from the subunits in order to determine the condition within the subunits that caused the trap to occur. A means is provided for storing a return address which allows for rexecution to continue at the next microinstruction that would have executed had a trap not occurred.

Abstract: A noningestible separation barrier having one or more pores or micropores  (of  one or more diameters) therein,  with the pores or micropores being initially plugged with one or more materials selected for its/their solubility and/or integrity characteristics relative to certain environmental conditions. Ordinarily, the pores or micropores of the noningestible separation barrier are initially  filled  with  at  least  one  material  having greater   erodibility,   under  a   given  environmental condition, than the material constituting the separation barrier itself.  The combination of the release rate (if any) or other membrane characteristic of the separation barrier,  combined with the release rate and/or erosion life of the plugged pores, enables complex separations including variable release of cells, colloids, solutes or solvents over time, such as when the plugged pores remain intact until erosion is triggered by an environmental change such as solvent addition or ionic conditions or pH or  thermal  change.    Particular  applications  include specialized   receptacles   and   protocols   for   the preservation of rooster sperm and turkey sperm for use in commercial artificial insemination applications.
