Abstract: ABSTRACT OF TEE DISCLOSURE         An escape slide and life raft assembly for evacuating personnel from an aircraft or other elevated place and thereafter providing a floating support when the evacuation is on water.  A slide portion of the assembly has side tubes connected to transverse and longitudinal tubes of an outrigger portion to provide additional seating capacity of the assembly when used as a life raft.  Upon inflation and extension of the slide portion, the outrigger portion is reefed or held in against the side tubes and only partially inflated so that the partially inflated longitudinal tubes reinforce the side tubes of the slide portion.  When the outrigger portion is fully inflated and extended by releasing the reefing, the pressure in the assembly will be reduced due to the increased volume of the inflatable support tubes; however, the reduced pressure is at a preferred level for operation of the assembly as a life raft.

Granted: 1983-12-27
Abstract: ABSTRACT OF THE DISCLOSURE           A belt clamp for use in conjunction with an emer-gency locking retractor in a vehicle occupant restraint belt system comprises a belt turning roll having the belt looped around it and carried by a pair of spaced-apart levers, one on either side of the frame, that are substantially rigidly joined together and mounted on the frame for rotation about an axis transverse to the frame.  Springs normally hold the turning roll and levers away from a movable clamping jaw that is supported by the frame to move toward and away from a matching fixed clamping jaw.  The springs yield to a sub-stantial pull out force on the belt, thereby enabling the lever and turning roll to pivot toward and to engage and shift the movable clamping jaw toward the fixed clamping jaw, whereupon the belt is gripped between gripping surfaces on the jaws and is prevented from pulling out from the emer-gency locking retractor.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates  to a method and a device for feeding rod-like articles, particularly cigarettes, by means of trays, to the feed hopper  of  handling machines, particularly cigarette-packing machines.  According to the invention, in order to assure  a  broad  time  period  to replace an emptied tray and to   practically   avoid   the sudden drop of the cigarettes  from  said  tray  into  the hopper therebelow, two trays  in  discharge  position  and aligned to each other in the direction of the hopper width, are arranged over the inlet opening  of  the  hopper.  The descent of the cigarettes into  the  hopper  is  permitted alternately only from one of the trays until it is emptied, while the other previuosly emptied tray is replaced with a stand-by full tray. The descent  of  the  cigarettes  into the portion of the hopper in register with the tray being emptied, is discontinued and prevented as soon as the tray has been emptied, so that the level of the cigarettes in the corresponding underlying  portion  of the  hopper  is maintained just below the lowest  layer  of  cigarettes  in the new full tray which is arranged in discharge position as a substitute for the emptied tray.

Abstract: HIGH SPEED TRANSISTOR SWITCHING CIRCUIT   ABSTRACT            A transistor switching circuit for switching a power transistor (28) from an on state to an off state at high speeds with minimal dissipation of power and without encountering secondary breakdown in the power transis-tor.  The transistor switching circuit includes a trans-former (36) having a secondary winding (35) connected to the base (30) of the power transistor (28) and a primary winding (49) connected to switching logic (38), the transformer (36) providing galvanic isolation between the power transistor (28) and the switching logic (38).  The switching logic (38) includes a first switch (50) and a second switch (52).  With the first switch (50) on and the second switch (52) off, the secondary winding (35) of the transformer (36) develops a positive base current applied to the power transistor (28) turning the transis-tor on.  To initiate switching of the transistor (28) off, the first and second switches (50,52) are both on, causing the secondary winding (35) to cease conducting current to allow collector charge carriers of the tran-sistor (28) to recombine.  After the collector charge carriers have sufficiently recombined, as sensed by a saturation sensing circuit (62), the first switch (50) is turned off, the second switch (52) remaining on so that the secondary winding (35) develops a negative current applied to the base of the power transistor (28), turning the transistor (28) off rapidly,  The transistor switch-ing circuit further includes means to limit the maximum base-emitter voltage of the transistor and means to reset the transformer core rapidly.

Abstract: HONEYCOMB MANUFACTURING METHOD AND PRODUCT              ABSTRACT         When conventional honeycomb structures are formed into cylinders, the inner wall made up of the inner edges of the individual honeycombs is circumferentially compressed and the outer wall made up of the outer edges of the honeycombs is circumferentially stretched.  As a result, the height of the inner wall increases and the height of the outer wall decreases resulting in a bowing in of the central portion of the cylinder so that the cylinder assumes an hourglass shape. This bowing in can be avoided by corrugating the original ribbon core material in the manufacture of the honeycomb in such a manner that one longitudinal edge of the corrugated ribbon follows a wave form of an amplitude greater than the wave form defining the opposite longitudinal edge.  When such formed ribbons are stacked and curved to form a cylindrical structure a the one longitudinal edge will be stretched and the opposite longitu-dinal edges will be compressed, resulting in an equalizing of the amplitudes of the respective wave forms defining these edges so that the lateral  wall of the resulting cylindrical structure in a direction parallel to the axis of the cylinder is rectilinear.

Abstract: MOBILE LOADING APPARATUS AND METHOD            ABSTRACT OF THE DISCLOSURE   Apparatus and method for loading material, particularly for use in underground excavations. Apparatus has a body supported on wheels or crawler tracks, which permits movement of the body on a surface, and a conveyor assembly mounted on the body to transport material from a front portion of the conveyor assembly to a rear portion thereof. Advancing structure cooperates with the conveyor assembly to cause essentially axial movement of the conveyor assembly as a reaction to force from the advancing structure. Penetrating structure mounted adjacent the front portion of the conveyor is adapted to be forced into material to be loaded and is rotationally oscillated about a horizontal transverse axis disposed normally to the longitudinal axis to facilitate penetration of the material. Use of advancing structure to force the penetrating structure into the material eliminates necessity for tractive forces applied to the wheels or tracks of conventional machines, thus overcoming scuffing or wear problems associated with such wheels or track. The body itself either carries the fixed conveyor assembly and is moved by the advancing structure as a total assembly, or alternatively the body is fixed by anchoring structure and the advancing structure moves the conveyor assembly relative to the body. The front portion of the conveyor can be raised to enter the material at a higher elevation.

Abstract: Abstract In a television receiver including an automatic kinescope bias (AKB) control system, a kinescope cathode is driven by a video output amplifier.  A feedback network is provided from the output to the input of the amplifier.          A sensing resistor is included in the main current conduction path of the amplifier.  During AKB operating intervals, a cathode output signal proportional to the cathode black current level is coupled via the feedback network for varying the amplifier conduction such that a voltage developed across the sensing resistor is proportional to the black current representative cathode output signal.          This voltage is utilized to control the cathode bias to maintain a desired black current level.
