Abstract: An electronic stereoscopic viewing device has an electronic signal generator which is coupled electronically to a liquid crystal display screen. The display screen upon receipt of a signal from the signal generator displays first and second views of an image with the first and second images being parallactically displaced with respect to one another. A first optical pathway conducts the first parallactically displaced view to a left eye viewing port and a second optical pathway conducts the second parallactically displaced view to a right eye viewing port. The optical pathways between the display screen and the left and right eye viewing ports are such that the first and second images are conducted to the respective left and right eye viewing ports in a manner maintaining the integrity of each such that the individually parallactically displaced first and second views of the images are received at the respective left and right eye viewing ports without contamination of one by the other.

Abstract: A status indicator for a door lock which is capable of being activated by a tail piece of the door lock has a first linking member which is operatively attached to the tail piece so as to be rotated by the tail piece and a second linking member which attaches between the first linking member and the indicating member. The second linking member translates the rotational movement of the first linking member to translational movement so as to move the indicating member linearly. The indicating member is housed within a housing plate which is attached to the door by the door lock. The indicating member moves within the housing member in response to change of the lock from a locked to an unlocked status and indicates this change so as to indicate the status of the lock, whether it is locked or unlocked.

Abstract: An article holder for stadium type chairs includes a support member which is positioned and held underneath the seat portion of a stadium type chair by a holding sock which slips over the seat portion. A shelf is slidably attached to the support member and slides between an extended position wherein a portion of the shelf extends beyond the front edge of the seat portion of the chair and a retracted position wherein the shelf is totally underneath the seat portion. During an event wherein the stadium type chair is occupied, if the occupant of the chair has purchased a beverage, hot dog or the like and wishes to place them somewhere without fear of their being spilled, kicked or staining the occupant's clothing and the like, the shelf is simply moved from the retracted to the extended position and the beverage, hot dog or other article is placed thereon without fear of spillage or the like.

Abstract: A toy has a body with a fly wheel rotatably mounted in the body. First and second appendages are rotatably mounted to the body and are connected to the fly wheel by a gear train. Further, a member is movably mounted on the body. When the member is in a first position the gear train is connected between the fly wheel and the appendages to move the appendages and propel the toy in a walking-like manner across a support surface. When the member is in a second position on the body the gear train is disrupted, the body is flipped so as to rest on the fly wheel, and the body is then rolled by the fly wheel across a support surface.

Abstract: A shift mechanism for a motorized toy includes a shift lever which is mounted on the toy so as to be able to move back and forth along an X axis and back and forth along a Y axis. The toy includes an electric motor and electric power supply for powering the same. A gear train connects the electric motor to an output shaft. A shift mechanism is connected between the shift lever such that movement of the shift lever along one of the X or Y axes shifts certain of the gears in the gear train to control the speed of the output of the output shaft. Movement along the other of the axes of the shift lever controls an electric switch which governs both the polarity of the current supplied to the motor to provide for both forward and reverse rotation of the output shaft as well as to break the circuit between the power supply in order to start and stop the toy.

Abstract: A speaker unit utilizing the sound radiation from the front and rear faces of a diaphragm can be constructed by placing the diaphragm in an acoustic baffle to isolate the back side and front side radiation and propogating the backside radiation through a tube to an acoustic resonator. This arrangement acoustically backloads the speaker and extends the frequency range over which piston-like motion of the diaphragm occurs without speaker breakup. A loudspeaker system producing good stereo image perception and suited for stereo sound reproduction for home or studio sound monitoring use can be constructed with a linear array of loudspeaker units. The sound radiation from the linear array is kept in phase over the audible range and through a wide angle about the axis of the array.

Abstract: A set of platens locatable as for instance on a die shoe and a slide die each contain a recess sized and shaped so as to partially receive one die of a set of dies. The platens further contain a wall which extends between the outer periphery of the platen and the recess with a hole extending through the wall and opening into the recess. The dies have a corresponding hole positioned in the dies so as to align with the holes in the walls when the dies are appropriately located in the recesses in the respective platens. A fastener has a shank with a handle having cam surfaces thereon located on one end of the shank and a flared head on the other end of the shank. A sleeve having a tapered tip fits on the shank between the cam and the tapered head with an expandable bushing then positioned between the sleeve and the head. Movement of the sleeve toward the head expands the bushing so as to lock the fastener in the aligned holes between the walls and the dies.

Abstract: A process for sealing anodic oxide coating on aluminum and aluminum alloys wherein organic substances with hydrolyzable functional groups like organo-functional silanes react with water at room temperature forming a silantriolic compound [according to the reaction: R'-Si(OCH.sub.3).sub.3 +3H.sub.2 O--R'-Si(OH).sub.3 ] which in turn reacts with the oxide coating forming a stable chemical bridge between silicon and metal thusly: ##STR1## Analogously the silantriol reacts with oxides of other metals such as Fe, Mn, Sn, and Cu commonly used for coloring, forming stable chemical bridges and therefore sealing the color.

Abstract: Induction heating can be utilized to cause necrosis of neoplasm as a result of hyperthermia by a process involving the injection of particles having hysteresis heating characteristics into tissue either within or in close proximity to the neoplasm and then subjecting these particles to an alternating magnetic field sufficient to cause hysteresis heating. The frequency of the field is preferably sufficiently low so as to minimize eddy current and dielectric heating. The particles used are preferably initially located within a biologically inert liquid carrier which will facilitate the insertion of the particles within the body and which will automatically become non-liquid within the body so as to hold the particles in place. The carrier may contain radiopaque material to enhance its visualization under radiographic examination.

Abstract: A hydrolyzed protein based on casein is prepared utilizing a process wherein casein as a solid is treated with sodium or potassium hydroxide in the presence of a limited amount of water. The amount of water utilized is insufficient to solubilize the casein such that at all times the casein and/or the hydrolyzed protein produced therefrom is present as a solid in an appropriate reaction vessel. The hydrolyzed protein is used as an additive to certain flesh containing food items as for instance seafood type products.
