Abstract: An operating string (OS) has upper and lower wipers (45), (26) with external seals thereon releasably connected to the operating string (OS). A lock arrangement (98), (210d), (230), (234), (235), (91b) prevents premature release of the upper (45) and/or lower (26) wiper by mechanical force, but is responsive to fluid pressure in the operating string (OS) to first release the lower wiper (26) from the operating string (OS) prior to release of the upper wiper (45). The upper wiper (45) cannot be released from the operating string (OS) until the lower wiper (26) has released from the operating string (OS). Seals (210), (217), (218), (45a), (45b), (45c), (45d), (231), (232) are provided to close off communication between the operating string bore (21) and the external wiper seals (29), (46b') to confine the pressure present in the operating string(OS) in a manner to assure release of the wipers (45), (26) as and when desired and in a sequence as may be desired. The wipers (45), (26) are each connected to the operating string (OS) to accommodate relative rotation therebetween to further reduce the possibility of malfunction or improper functioning in releasing the wipers (45), (26) and to permit the operating string (OS) to be manipulated without releasing the wipers prematurely.

Inventor: ANDERSON MARK R
IPC: H03G7/06
Filed: 1991-01-17
Abstract: ABSTRACT A decoding arrangement for decoding audio signals previously encoded in accordance with the dbx format, includes a wideband expander instead of a full dbx expander.  The wideband expander employs a relatively simple, and therefore inexpensive, peak detector in place of the true RMS detector of a full dbx expander, and does not include apparatus for spectral expansion of the audio signal.  Although the decoding is noncomplementary with respect to the encoding, the stereo audio reproduction as perceived by a listener, is surprisingly good.

Title: Electrical contactor with controlled closure characteristic
Inventor: HURLEY RICK A
IPC: H01H47/22
Filed: 1991-01-25
Abstract: Abstract of the Disclosure A microprocessor  controlled  electrical  contactor monitors the voltage and peak current produced by a first voltage  pulse  gated   to   the  coil  of   the  contactor electromagnet and adjusts the conduction angle of the second pulse to deliver a constant amount of electrical energy to the electromagnet coil despite variations in coil resistance and  supply voltage  so that the contactor contacts can be consistently  closed  with  low  impact velocity  and minimum contact bounce.   Normally, the third and subsequent pulses are gated to the coil at constant conduction angles selected so  that  the  contacts  consistently  touch  and  seal  on  a preselected  pulse  with  declining  coil  current.   Under marginal conditions, determined by the peak current produced by the  first   pulse,  the third and subsequent pulses are gated  at  substantially  full  conduction angles  to  assure contact closure.  If the voltage or current produced by the first  pulse  is below  a  predetermined  value,  closure  is aborted.

Title: Fusion detecting system for relays
Inventor: HOSHINO YOSHINORI
IPC: H01H47/00
Filed: 1990-08-29
Abstract: ABSTRACT OF THE DISCLOSURE      A fusion detecting system for relays is provided for detecting a fusion of relay contacts.  Two fully-interlocked or semi-interlocked relays are connected in such a manner that they operate under identical conditions, and a fused state is detected based on the states of signals sent from series-connected make contacts and series-connected break contacts of the two relays.  In the case of semi-interlocked relays (R1, R2), if a make contact (r12) is fused during a current supply to a coil, the other contact (r22) remains in an open state or at a make-contact side after the current supply to the coil is cut off, and if a break contact (r11) is fused, the other contact (r21) remains in an open state or at break-contact side after a current is supplied to the relay coil.  Accordingly, by using two semi-interlocked relays under identical conditions and connecting same such that the make contacts and the break contacts are individually connected in series, a fusion of the relays can be detected based on signals sent from the contacts.  A fusion of fully-interlocked relays can be detected in a like manner.

Inventor: BUBIC FRANK R
IPC: B25J18/06
Filed: 1991-04-02
Abstract: Single or multiple flexible robotic manipulator trunks can be made from individually activated,  three degree-of-freedom, flexible robotic links.  Threedimensional positioning and orientation of the distal end of each link is achieved exclusively by elastic deformation of the flexible link assembly without revolute or prismatic joints. The activating bending and torsional moments required for such a positioning are generated by the antagonistic action of  a plurality of prestressed,  inflatable,  laterally bendable and axially extensible tubular actuators with the anisotropic,  circumferentially reinforced walls.   The positioning motion, working forces and manipulator arm stiffness are all controlled by asynchronously modulated pulse streams which regulate the distribution of energy from a common source of fluid under constant pressure.

IPC: C08G77/06
Filed: 1992-01-09
Abstract: METHOD FOR MAKING SILICA REINFORCED SILICONE SEALANTS     Abstract A process for producing a silicone elastomeric base consists essentially of mixing treated fume silica and hydroxyl endblocked polydiorganosiloxane oligomer, polymerizing with sulfonic acid or quaternary ammonium carboxylate catalyst while controlling the atmosphere in the mixer to a controlled partial pressure of water vapor to control the molecular weight of the polymer produced, then terminating the catalyst, to give a silicone elastomeric base of hydroxyl endblocked polydiorganosiloxane having fume silica reinforcement.  The base can be further combined with a moisture activated crosslinking system to give a moisture activated silicone sealant.  The thixotropy of the above sealant can be controlled through the post addition of small amounts of a thixotropic promoter, such as untreated fume silica.
