Abstract: INVENTOR:    ROLF LEHMANN          INVENTION:   CONTROLLED DEFLECTION ROLL                 ABSTRACT OF THE DISCLOSURE           A controlled deflection roll having a stationary roll core or support and a roll shell mounted to be rotatable about the stationary roll support.  The roll shell is supported upon hydrostatic pressure or support elements, each of which possesses a number of bearing pockets flow connected by means of throttle channels with a pressure chamber.  The pressure elements are in the form of plates dispositioned in the inter-mediate space between the inner surface of the roll shell and the outer surface of the stationary roll support or core.  This stationary roll support can have a substantially cylindrical or planar outer surface at the location where it is engaged by the pressure element.  The pressure element can be retained in position by pins secured at the stationary roll support or core, these pins engaging with clearance or play into recesses of the related pressure element.  The pressure element also can take the form of an elongate strip or ledge having a number of seals bounding separate pressure chambers.

Title: Hydraulic emergency hand tools
Inventor: KEIGLEY RONALD E
IPC: F15B15/18
Filed: 1979-07-23
Granted: 1980-11-18
Abstract: ABSTRACT           The specification discloses A hydraulic pressure operated emergency hand tool of the type in which manual pressure exerted on an all position small-area pump piston creates a hydraulic pressure which is communicated to a power cylinder for activating a plural jaw tool member, such as a pair of cutter blades.  The jaw members are pivoted together intermediate their ends and one end of each is pivotally connected one to the power cylinder opposite the free end of the piston and the other to the free end of the piston.  A release valve provides instant return displacement of hydraulic medium via a by-pass communi-cation from the cylinder to the reservoir to relieve the acti-vating pressure on the cutter blade and restore it promptly to normal position.   Interchangeable tool members are provided.

Abstract: ABSTRACT       A gas recovery method and apparatus for the recovery and storage of a gas from a gas enclosure or circuit particularly for the recovery of sulphur hexafluoride (SF6) from the arc chamber of a high voltage/current circuit breaker.  A gas bottle is connected via quick connect coupling and a non-return valve to the gas circuit or en-closure.  The gas bottle is immersed in a liquid nitrogen environment in a Dewar flask thereby generating a self pumping action as the sulphur hexafluoride liquifies (or solidifies) within the gas bottle due to the temperature of the liquid nitrogen (-196°C) being well below the phase change temperature of the sulphur hexafluoride over the range of encountered vapour pressures.  When the gas has been recovered, it is stored in the gas bottle which is returned to ambient temperature by removal from the liquid nitrogen and/or by immersion in a heated bath.  The gas bottle is reconnected to the gas circuit when recharging of the circuit with the recovered SF6 is required.

Abstract: TWO PIECE FASTENER AND INSTALLATION TOOL            ABSTRACT OF THE DISCLOSURE           A two piece pull-type fastener is disclosed herein comprising a pin and h collar adapted to be swaged into locating engagement with the pin upon setting of the fastener by applica-tion of a pulling force to the pin and reaction force on the collar.  The pin is provided with a minimum number of pull grooves defined by alternating crests and valleys which grooves are sufficient in strength to allow an installation tool to exert a pulling force on the pin of a magnitude required to properly set the fastener.  The installation tool has a gripping structure adapted to engage the pull grooves.  The gripping structure and pull grooves are complementarily shaped so as to prevent engagement of less than all of the pull grooves by the gripping structure of the tool in order to prevent stripping of the pull grooves if less than all are attempted to be engaged.  Thus an installation tool nose assembly is also disclosed which nose assembly is uniquely designed for use with the present fastener.  In a preferred form of the invention, the pull grooves of the fastener are provided on a pintail portion of the fastener.  In a different form of the invention the pull grooves are located within an opening in the end portion of the pin.

Title: Containers and other liquid-holding means

Granted: 1982-07-06
Abstract: Abstract of the Disclosure A container or other liquid holding means, e.g. a pipeline, for inflammable liquids is provided with a fire-extinguishing structure.  This comprises a blanket of a porous, flame-permeable, heat-resistant material, e.g. expanded metal foil, which is supported for contact with the surface of the liquid e.g. on floats embedded in the blanket, so that the blanket extends in contact with substantially the whole of the liquid surface.  In the case of a pipeline, the blanket may be supported adjacent the pipeline in a normally-empty catchment facility which is intended for retaining spillages or leakages of liquid from the pipeline. The blanket has large non-capillary interstices.  On ignition of the vapour/air mixture above the blanket, the flame front recedes downwardly into the blanket and the flames become extinguished.  This arrangement can reduce the fire hazard associated with large-capacity containers for inflammable liquids.

Abstract: Abstract of the Invention This invention relates to a device for automatically monitoring the charging state of the independent current supply of the transponder of a network for determining the position of traffic systems, wherein there is coordinated with the current supply (primary batteries or accumulators ad-apted to be charged via solar cells) a monitoring sensor with a defined re-sponse threshold.  The humidity of the ambient atmosphere is additionally monitored by providing a sensor inside the device.  The sensor indicates any excess of a predetermined limiting value of the humidity inside the trans-ponder which under normal operational conditions is kept at low values.  If the humidity sensor detects excess humidity, it produces a signal which is mixed with the monitoring signal via an OR gate and included in a response telegram to be sent to an  interrogating unit.

Abstract: ABSTRACT            The invention relates to a device for sealing of the aperture (2) which is made in a weapon cupola (1) for the barrel (3) of the weapon and which shall permit elevation movements of the barrel. The device consists of an elongate bellows (4) made of plastic material which along its entire length is divided up into two halves (5, 6) which are in contact with each other along the centre line (7) of the barrel aperture. The barrel (3) then extends out between and presses the two halves (5, 6) of the bellows apart. Because of the bellows-shaped elastic material, this pressing apart can easily take place, and the bellows (4) resumes its shape and covers the barrel aperture (2) both below and above the barrel (3). In order to cover the gap which arises just above and below the barrel (3) this is provided with a protective plate (15) the form of which is adapted to the bellows (4) and thus participates in the elevation movements of the barrel.
