Title: Pre-pressurized accumulator for hydraulic brake  system
Inventor: JONES ED F
IPC: B60T13/14
Filed: 1984-09-21
Granted: 1988-06-28
Abstract: Abstract Disclosed is an accumulator for use on hydraulic brake systems. The accumulator includes a housing, a pressurization cap which is threadably connected into the housing and a resilient bulb contained within a volume between the housing and pressurization cap. The resilient bulb provides a flexible volume which can expand in response to high pressure surges and shock waves experienced by the braking system. The bulb is contained primarily within an interior cavity formed in the pressurization cap. The resilient bulb is constructed in a size and shape which causes an annular volume between the bulb and pressurization cap to be pre-pressurized when the accumulator is assembled together. The accumulator is also provided with a particularly effective sealing arrangement to prevent leakage of air and hydraulic fluid from around the bulb.

Abstract: ABSTRACT OF THE INVENTION      A method and apparatus for detecting wear of a rotatable bit used to drill a wellbore is disclosed.  In drilling operations, a drilling fluid is pumped down through a drill stem and is discharged through ports in the drill bit and into the annulus between the drill stem and the wellbore.  Excessive wear of the bit at a selected location is detected by a sensor which is linked to a restrictive device capable of reducing the flow of drilling fluid through at least one port.  To detect excessive wear of the bit, at least one abradable sensor is located in the bit at a selected location.  As the drill bit wears at the location, the sensor will abrade until the sensor is activated.          Activation of the sensor is transmitted by a communication device such as a wire or hydraulic fluid to manipulate the restricting device.  More than one sensor may be simultaneously linked to the restricting device with communication devices to detect wear of the drill bit at differing locations.

Abstract: FLUID INFUSION SYSTEM            ABSTRACT OF THE DISCLOSURE          A  fluid  infusion  system includes a selector valve for convenient interruption  of administration of a  primary  infusion  fluid  to  a  patient  to  permit administration of a secondary infusion  fluid,  such as a  selected  drug  solution, followed by resumption  of primary fluid flow.    The  selector  valve  includes a valve housing with a primary spike for connection  to a primary  fluid  container,  a dual path secondary spike for  connection to a vial or the  like  containing  the secondary  infusion  fluid,  and  an outlet fitting for connection  to  the  patient,  for example,  through  a standard  intravenous (IV)  infusion  set.    A  valve insert is movably mounted within  the valve housing and defines  a fluid channel network for  controlling  flow from the primary  and  secondary  spikes  to the outlet fitting.    In  one  form, the valve insert is  movable between a first position  routing  the primary infusion fluid directly from the primary spike  to  the  outlet fitting  for  supply  to  the patient,  and  a  second position  routing  the  primary  infusion fluid through the secondary spike and the vial to  wash the secondary infusion  fluid  therefrom  through the outlet  fitting for flow to the patient.  In  an  alternative form, the valve  insert  is  movable to an intermediate  position for coupling the primary  infusion  fluid  through  the secondary  spike  to  a vacuum vial for reconstituting, for  example,  a dried phramaceutical  therein  without supply to the patient,  after which the valve insert is movable to the second position  permitting  fluid  flow from  the  vial to the outlet fitting.  Upon completion of secondary  infusion  fluid  administration,  primary fluid  administration resumes  automatically  by  flow thereof  through  the  vial  and  outlet fitting to the patient.

Abstract: ABSTRACT OF THE DISCLOSURE           WATER DETECTION SUBASSEMBLY AND METHOD OF FORMING SAME, FOR USE IN ASSOCIATION WITH WATER DETECTION SYSTEMS IN COMPUTER PORCESSING  CENTERS          The present invention relates to a water detection subassembly and method for forming same, for use in association with water detection system operating within a digital computing central.  The subassembly includes a perforated protective shield fitted about a fabric mesh supporting copper conductors connected to a low voltage service.  In that way, the shield completely isolates the fabric mesh and copper conductors against abuse such as provided from workmen's shoes coming into contact with the subassembly during repair, replacement or renovation a computing equipment at the center.          The shields are conveniently formed from commercially available plastic pipe such as PVC, sliced longitudinally and then attached to the concrete sub-floor of the computing room along the two cut longitudinal surfaces.  Since a pair of shields can be formed from each section of plastic pipe, the shields are inexpensive to manufacture.    Installation (and replacement) is facilitated by using a concrete stude gun to insert head-less studs into the concrete sub-floor through each shield followed by capping the subassembly with wing nuts.  A series of semi-circular openings along the shield give the shield a scalloped look and permits water an easy route into the interior of the subassembly.

Abstract: CHANNEL ALLOCATION ON A TIME DIVISION MULTIPLEX BUS    Abstract of the Disclosure A novel method and apparatus for quickly allocating channels on a TDM (time division multiplex) bus to devices requesting access to those channels.  In one embodiment, each channel of the TDM bus consists of nine bits and each device has a unique eight bit identification code plus one status bit (referred to collectively as a unique nine bit device code). If a channel is not occupied, each device wishing to gain access to the channel applies its own unique nine bit device code to the bus in the channel time period, sequentially, in order of significance.  While doing this, each device monitors the bus to determine what code signal is on it; as soon as it detects a code bit differing from its own, it declares a conflict and stops sending its code, only to wait for the occurrence of the next channel when it retries.  The device that is successful in applying all the bits of its code to the bus without conflict declares itself to be the winner, and on the next appearance of that channel (i.e. in the next frame) it transmits as the first bit in the channel a status bit set to alert other contenders for the channel that it is taken.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE The invention discloses a lure, a lure guide, or the like, utilizing a gravity activated diverter which causes them to follow an irregular pattern to simulate the swimming pattern of a minnow.  A body member is provided with a first passageway extending transversely thereof a short distance rearwardly of the forward end and opening through the side surfaces of the body member.  A second passageway extends in from the forward end of the body member and communicates with the second passageway at a point intermediate the sides of the body member.  A combination check and flap valve is provided on each side surface.  The flap valve is hinged at a forward point relative to the side opening and allows only outward flow of water from the transverse passageway through the sides.  A ball is disposed in the transverse passageway and is associated with the flap valves for controlling the outward flow of water through one or the other of the valve assemblies depending upon the positioning of the ball resulting from gravitational or side thrust forces acting on the body member.  The movement of the ball relative to the valves causes unbalanced water pressure at one or the other of the side surface openings to cause the body member to change direction in an irregular movement. Pole line connecting means are provided on the top forward portion of the body member to control direction of movement and diving capabilities.  The device may be shaped like a minnow, including forming the flap valves at the sides to resemble gills.  Also, the forward opening in the body member can be enlarged and made to resemble an open mouth of a minnow.  Also within the concept of the invention is a shiftable weight attached to the device for providing the fisherman with a great number of dive choices.
