Abstract: METHOD AND APPARATUS FOR EXTENDING THE ENVIRONMENTAL      OPERATING RANGE OF AN INK JET PRINT CARTRIDGE               Abstract of the Disclosure An ink jet print cartridge includes an ink reservoir, a print head for ejecting ink from the reservoir and first and second pressure control mechanisms for limiting the reservoir underpressure. The first pressure control mechanism limits reservoir underpressure by controllably introducing replacement fluid (i.e. air or ink) thereto.  The second pressure control mechanism limits reservoir underpressure by changing the volume thereof.  The two pressure control mechanisms cooperate to regulate the underpressure in the reservoir at a desired value over a broad range of environmental excursions and permit use of a volumetrically efficient package.

Abstract: For covering hitch balls on the hitch systems of cars a loose covering hood is usually used, which is placed over the hitch ball (6) and which may easily be lost if it is loose, or create noise if it is suspended in a chain, when the ball is being used. By the invention is provided a covering hood by means of two semi-spherical shells (24) which are pivotally fastened to the hitch rod (4) right below the hitch ball (6), such that they are pivotal from a covering position closed about the hitch ball to opposite projecting positions, in which the hitch ball is uncovered. On already existing hitch systems the shells (24) are easily mountable by means of a simple clamp fitting, which is even well suited to be fixed on a conical hitch ball rod.

Abstract: Before winding-up the printed products arriving in imbricated product formation, the thickness of the imbricated product formation travelling toward a winding mandrel, respectively toward a product coil or package forming thereupon, is regulated to a prescribed value. This is effected by spreading or compacting the printed products within the imbricated product formation. For this purpose a first conveyor device is driven at higher or lower speed than a second preceding conveyor device. The imbricated product formation of prescribed thickness is wound-up upon the winding mandrel together with a winding strap maintained under tension which always lies upon the outer side of the coil layer being formed. By regulating the thickness of the imbricated product formation to be wound-up so as to have a prescribed value which remains essentially constant throughout the winding-up procedure, it is possible to form product coils of essentially constant diameter with a prescribed constant length of winding strap independently of the thickness of the arriving printed products.

Abstract: The present invention relates to a method and an apparatus for washing pulp according to which method the pulp is supplied onto a movable liquid-pervious support surface (2) to form a substantially continuous layer (7) and washing liquid is supplied to the pulp layer (7) and passed in several successive washing phases through different area of the layer in such a way that the washing liquid gradually flows in the opposite direction compared with the flow direction of the pulp layer. According to the invention the washing liquid is divided by means of pipes (12-17) in two or more partial flows which pass alternately through different washing phases in such a way that the washing liquid which in one phase has passed through the pulp layer (7) flows past at least the washing phase preceding it in the flow direction of the pulp layer (7). The apparatus of the invention preferably comprises a rotating cylinder (1) the casing surface (2) of which serves as the liquid-pervious support surface for the pulp.

Abstract: The industrial truck or vehicle comprises a support body or member supporting an elevatable platform. The support body is supported and guided on both ends by a respective transverse pivot joint of a respective driving module or unit. The width of the support body and the platform is narrower than the width of the two driving units. This narrowing or reduction in width of the industrial vehicle ensures that the complete platform region on both longitudinal sides of the industrial vehicle is manually accessible despite providing good lateral vehicle stability. Furthermore, the torsional elasticity of the support body is increased such that the support body in combination with the transverse pivot joints provide sufficient travel surface adhesion or floor traction of all drive wheels and support or free-running wheels even over irregular or uneven travel surfaces. The industrial vehicle possesses an emergency recovery device so that it can be temporarily driven without auxiliary devices if up to two wheels become blocked. For this purpose the driving units are tilted individually or in combination about the still functional wheels by means of a respective drive spindle until the blocked wheels are free of the floor or ground surface and the industrial vehicle is rendered mobile. The reduction in width of the industrial vehicle and the autonomous capability of recovering from emergencies permits this industrial vehicle to be utilized in flexibly-organized assembly plants, especially in the automotive industry.

Abstract: Method and means of conveyance for solid material, f.ex. tree trunks (6) or bark, whereby the solid material is conveyed with parallel, oblong transfer elements (4) moving back and forth in transfer direction. A larger part of the surf ace of the transfer elements (4) is moving forward at a time than moving backward. The speed of the return motion of the transfer elements is higher than that of the feed motion of the trans-fer elements. Transfer elements (4) at sides of the conveyor have been inclined on their longi-tudinal axis so that they slope towards the centre of the conveyor. In this way the friction force between the particles (6) of the material to be conveyed is increased and the friction force between the maternal (6) to be conveyed and the transfer elements (4) is decreased.

Abstract: A self-synchronizing servo control system and its associated servo data code for use in a high-density disk memory is disclosed.  The servo data is formatted into a sync/index zone and a data zone.  Sync and index di-bits are written only in the sync/index zone, while only servo data position di-bits are written in the data zone.  Elimination of the sync and code di-bits used in prior art methods removes all requirements for radial phase coherence during the writing process, and increases the servo sample frequency.  The new servo data code also reduces the intersymbol interference seen by adjacent pulses.  The associated configuration of the servo control system is also disclosed.

Title: Process for the manufacture of a carbon fiber reinforced composite material having a ceramic matrix
Inventor: ROCHER JEAN-PHILIPPE
IPC: C04B35/571
Filed: 1991-02-05
Granted: 2002-08-06
Abstract: In the process according to the invention, before the ceramic matrix is densified, the carbon fiber reinforcement material is subjected to a thermal treatment in a non-oxidizing environment at a temperature greater than 1300° and less than 2200°C, to act on the bonding between the fibers and the matrix.      If a preform of the carbon fiber reinforcement material is formed prior to densification by a matrix, then the thermal treatment may be performed on the preform, prior to densification by the matrix.      If the matrix is densified by chemical vapor infiltration inside a furnace, then the thermal treatment may be performed inside the infiltration furnace prior to the densification.      The thermal treatment grants a significant improvement in the strength of the resulting composite material.

Granted: 1994-01-25
Abstract: Abstract of the Disclosure The present invention provides a cryogenic storage container having a pressure vessel surrounded by a vacuum vessel  for maintaining a vacuum between the outer wall of the vacuum vessel and the pressure vessel.  A pair  of  intermediate  and  sub-intermediate  heat  shields  are  disposed between the outer wall of the vacuum vessel and the pressure vessel for intercepting the heat that could otherwise be transferred from the vacuum vessel to the pressure vessel.  The heat intercepted by the intermediate heat shield is absorbed by liquid  nitrogen  contained  within  a liquid nitrogen  container.   The heat intercepted by the sub-intermediate heat shield is preferably absorbed by liquid neon in a  liquid neon storage tank.   The liquid nitrogen and neon absorb heat by undergoing a phase change, from liquid to vapor.  In order to prevent failure of the liquid nitrogen container, the nitrogen is vented to the atmosphere over a period of time.  The vaporized neon, on the other hand, flows into an adsorbant canister  containing  activated  charcoal  to  adsorb  gaseous  neon  for regeneration back to liquid neon at a future time.
