Title: Downhole chemical cutting tool
Inventor: TERRELL JAMIE B
IPC: E21B29/02
Filed: 1989-11-21
Abstract: A downhole chemical cutting tool having an anchoring system employing interchangeable slip arrays of progressively larger outside diameters that can be used economically to adjust the range of the anchoring system.  The range can be further adjusted by utilizing interchangeable slip expansion mandrels.  This anchoring system both anchors and centralized the chemical cutting tool.  The cutting tool includes a slip shaft that provides fluid communication between the propellant section and chemical section, thence to the slip piston that receives the interchangeable slip arrays.  The slip shaft and slip piston are threadedly connected to a set coiled tension spring.  Interchangeable slip expansion mandrels connected to the slip shaft below the slip arrays are constructed with ball bearings on the surface that receives the slip arrays expanding the slip segments into a gripping engagement an usually large angle as the slip piston is actuated by the application of fluid pressure during the cutting operation. The interchangeable slips are configured so that the gripping teeth will simultaneously engage the internal surface of the wellbore pipe being cut. During the cutting operation the application of fluid pressure activates the slip assembly and discharges the chemical cutting fluid from the chemical section into the fluid jet section of the tool at high temperature and velocity.  After the release of fluid pressure the slip assembly reliably releases the tool due to the large    ' angle of engagement of the slip segments.

Title: Fast response load sense control system
Inventor: VOSS DENNIS A
IPC: F15B11/16
Filed: 1990-03-22
Abstract: FAST RESPONSE LOAD SENSE CONTROL SYSTEM     ABSTRACT  A source of pressurized hydraulic fluid has a variable fluid output rate and a control system which varies the fluid output rate responsive to a load sense control signal, e.g., a variable displacement pump.  The pressurized fluid is made available to a plurality of hydraulic actuators through a corresponding plurality of work control valves.  A load sense line is utilized to sense the pressure of the fluid in each hydraulic actuator and to apply a total load sense signal to the control system.  A conduit containing a pressure reducing valve provides fluid communication between the output of the source of fluid and the load sense line to pass fluid therethrough to the load sense line only when the pressure in the load sense line is less than a predetermined value.  Maintaining at least this minimum pressure in the load sense line minimizes lag in the load sense signal which would otherwise occur as a result of the loss of fluid in the load sense line due to the bleeding of the load sense line.

Title: Packaging material of laminate type
IPC: B32B27/28
Filed: 1990-10-15
Abstract: A flexible, laminated material for reforming into packages for contents of the type such as oxygen-and flavour-sensitive liquid foods, for example fruit juices.     The material displays a carrier layer of paper or paper-board and a preferably extruded layer applied to one face of the carrier layer (corresponding to the inside of the finished package), this layer consisting of a mixture of polyethylene and ethylene vinyl alcohol copolymer.     Since the barrier layer thus includes both a polar (the ethylene vinyl alcohol copolymer) and a non-polar (polyethylene) component, the material possesses barrier properties against both polar and non-polar flavour components, at the same time as the material moreover displays tightness properties vis-à-vis oxygen.

Title: Eye dropper
Inventor: LENEAL DENISE L
IPC: A61M35/00
Filed: 1990-10-15
Abstract: ABSTRACT OF THE DISCLOSURE      An eye drop guide has a contoured base to rest on the bony surround of the eye socket.  This bony surround is more or less invariant in the adult human, regardless of sex, race and size.  The guide also has a dropper aperture to receive a eye drop container nozzle, this aperture is located at least 30 mm above the base to prevent eye drop nozzle-eye lash interference and blinking.  The aperture is also centred about 29 mm outward of the inner end of the eye socket and thus above the inner triangle of the open eye, between cornea and the inner corner of the open eye.  This is the most desirable point for eye drop introduction.  The contoured base has a specific shape, and can be used for left and right eyes interchangeably.  The advantage over the prior art is that the guide automatically fits into position with the dropper aperture over the best eye drop position. Advantageously a dropper funnel and a drop container holder are associated with the aperture.

Title: Cordless telephone apparatus
IPC: H04M1/72508
Filed: 1990-10-29
Abstract: ABSTRACT OF THE DISCLOSURE        A cordless telephone apparatus having a connecting unit and a cordless telephone set.  The apparatus processes a completing call signal sent from the connecting unit and an originating call signal sent from the telephone set by giving priority to either one of the two signals.   In a preferred embodiment which gives priority to originating call  processing,  the  connecting  unit  stops  sending  a completing call signal and, instead, sends an originating response signal when an originating call signal with a coincident identification signal  is detected during the course of transmission of the completing call signal.  The telephone set also sends an originating call signal when a carrier with a coincident identification signal is received. In  an  alternative  embodiment  which  gives  priority  to completing call processing,  the connecting unit sends a completing call signal on receiving an originating call signal  with  a  coincident  identification  signal.    The telephone set, even during a call originating procedure, stops transmitting an originating call signal and, instead, sends a completing response signal when it receives  a completing call signal with a coincident identification signal.
