Title: Crash survivable enclosure for flight recorder
Inventor: GROENEWEGEN JOHANNES B
IPC: H05K5/02
Filed: 1990-09-04
Abstract: CRASH SURVIVABLE ENCLOSURE FOR FLIGHT RECORDER             Abstract of the Disclosure A crash survivable enclosure (10) for flight data recorders used in aircraft and other vehicles operating over land and water includes a strong, light-weight metal shell for enclosing and protecting an information storage device (24) having power, signal, and address lines (22) connected thereto.  The memory device is supported inside the shell in a wax filler (46) having a high melting temperature and a high heat of fusion to act as a heat sink for absorbing a large quantity of heat to minimize possible damage to the memory device because of excessive heat, flames and/or high temperature.  A strong lightweight metal shell (50) is provided to enclose and protect the inner shell and contents against substantial, external mechanical forces commonly occurring in a crash and flames, heat and fire resulting therefrom.  A second filler (60) of high efficiency, heat insulating materi-al is provided for physically supporting the inner shell and contents and providing protection against flame, fire and heat penetration as well as physical impact and shock penetration as would be encountered in a crash of an aircraft or other vehicle carrying the enclosure.  The enclosure is especially designed to withstand prolonged immersion in salt water at substantial depths to provide protection against damage to the memory device so that pertinent recorded infor-mation is available upon retrieval of the enclosure after a crash.

Title: One piece channel suture package
Inventor: SOBEL MARTIN
IPC: A61B17/06
Filed: 1990-09-11
Abstract: A one piece needle and suture holder is described in which a rounded channel is formed for retention of the suture. One end of the suture exits the channel toward the interior of the channel and is attached to a needle located in a needle holder in the interior of the channel. The channel is formed with an open side, to which are attached a plurality of hinged doors. After the suture is wound in the open channel, the doors are folded over the open side of the channel and are locked in place to retain the suture within the channel. In an alternative embodiment a paper cover is utilized to complete the enclosing channel. To afford ease of winding the suture the bottom of the channel is perforated for the application of a vacuum to the channel during suture winding. Also disclosed is a needle park for retaining the needle in the center of the package. In a preferred embodiment the needle park is backed by a relief flap to enable the needle to be conveniently grasped by a forceps during removal of the needle and suture.

Abstract: ABSTRACT OF THE DISCLOSURE      A form,  fill,  seal and separate packaging machine for reclosable containers is accomplished by a plurality of stations disposed along a path of travel of a thermoplastic web (12) including a pair of mated, resealable closure strips present on the base web.   The machine is intermittent in its operation, with movement of the web through the machine controlled so that the various steps of forming,  filling,  sealing  and  separating  the reclosable containers are performed during periodic stops of the machine.   The machine is further characterized by its use of two pairs of web belts to move the web through the machine.  A first pair of web belts (26 and 28) initially receive the folded web  stock  (12)  and  partially  form and completely fill the containers.  The second pair of web belts (82 and 84) overlap with the downstream end of the first pair of belts (26 and 28), but are disposed lower than the first belts.   When the filled partially formed containers pass from the first pair of belts (26 and 28) to the second pair of belts (82 and 84), the unsealed free ends (40) are exposed for final sealing and severing.

Inventor: MOWER MORTON M
IPC: A61N1/365
Filed: 1991-05-15
Abstract: A method and apparatus for cardioverter/pacemaking utilizing neurosensing. The invention utilizes the baroreceptor nerves found in the body.  A neurosense electrode is placed around the carotid sinus nerve and a sense amplifier with automatic gain control and an integral  band pass  filter provides  a  frequency-to-voltage converter with a frequency proportional to the stimulus received from the carotid sinus nerve.  The voltage from the frequency-to-voltage converter is sent to the analog-to-digital converter where it is bussed to a microprocessor.  The microprocessor then drives a pacing  lead  and  in the presence of  a  cardiac  signal  the microprocessor provides a cardioverting signal to the cardioverting lead if ventricular arrhythmia is sensed.  The microprocessor also drives a telemetry coil and receives ventricular information from the ventricular sensing lead.

Title: Derrick assembly capable of conveying pipe sections between a drill string and a rack for said pipe sections
Inventor: ROWBOTHAM RONALD H
IPC: E21B15/00
Filed: 1991-05-16
Abstract: A derrick assembly capable of conveying pipe sections between a drill string and a rack for storing the pipe sections. The assembly includes a frame having lateral sidewalls and a base together defining an elongated channel having an open outer side opposite to the base. A rack for housing pipe sections is positioned within the channel adjacent to one lateral sidewall leaving part of the channel clear for manipulating the drill string. The rack is formed by a number of elements extending between the base and the open outer side for housing pipe sections oriented generally longitudinally within the channel. A gantry extends across the open outer side of the channel and is movable longitudinally of the channel. The gantry supports a pipe gripping unit for selectively gripping or releasing pipe sections capable of moving towards or away from the base and laterally between the sidewalls. The pipe gripping unit can thus convey pipe sections between the rack and the clear part of the channel by appropriate movements in the stated directions.

Filed: 1991-08-26
Abstract: ABSTRACT   A method is disclosed for developing the contour of tools employed for forming aluminum alloy members exhibiting complex shapes. The members are precipitation, heat-treatable, aluminum alloys which are age formed. The resulting member is formed to the desired contour and, simultaneously, is heat treated to reduce residual stresses while improving its strength characteristics. The invention is particularly concerned with a new tool contour prediction method which is based upon the relationship, for a particular aluminum alloy, of the strain retained in a part after it has been subjected to an applied strain while constrained to a desired shape, then released after being heat treated in an autoclave or furnace.

The pump or internal combustion engine comprises a cylindrical vane housing having inlet (intake) and outlet (exhaust) ports (and an ignition or injection device) with a pair of vane rotors installed within between two cylindrical drive housings, each containing a means for converting between rotary and rotating reciprocating motion. Each of the vane rotors defines a pair of diametrically opposed vanes and has a circular end wall at one end to create four enclosed chambers when thevanes are interdigitated within the vane housing. A drive shaft passes through the entire assembly connecting to both means for converting motion and is journalledin endplates mounted to the drive housings. Each means comprises a pair of diametrically opposed crankarms journalled at each midpoint in a vane rotor, each crankarm having a pair of outer shafts that engage, via a slider and roller, slots in a drive flywheel affixed to the driveshaft and a cam on an endplate respectively, the cam acting to determine the location of the crankarm outer shafts along the slots as the drive shaft and flywheel rotate thus imparting reciprocating motion to the vane rotors via the crankarm midpoint connection, and to constrainsaid outer shaft location to enable the driveshaft rotary motion to be imparted via the drive flywheel slots and crankarms to the vane rotors.

Filed: 1991-12-20
Abstract: A helically shaped tube (1) is provided, through which the cable (3) is pulled, in order to damp shocks in a wire cable which is stressed in tension. The two tube ends are held together by a compression sleeve (2). In the event of accumulations of fallen stones and snow, a shock load acts on the cable, deforming the tube (1). This produces an extension of the cables. The kinetic energy is progressively reduced by the plastic deformation of the material.
