The rails may be manufactured in a variety of shapes including “I” beams, rectangles, boxes, or even ovals or circular shapes. Some embodiments of the ladder include a pulley assembly which is fastened to a fly rail rung and a rope is passed through the pulley to form a continuous loop around the rungs of the base set of rail rungs and the fly fail rungs. In addition, some embodiments include means for attaching tools to the fly rail.
Abstract:
A pneumatic fastener inserter and hopper for the same is disclosed for use in inserting fasteners into material being secured. The hopper comprises a rotatable drum which tumbles the fasteners therein into position so that the shanks thereof protrude outwardly between spaced-apart bars. The fasteners are discharged from a discharge opening formed in the hopper and are delivered to a magazine which is in communication with an entrapment apparatus which feeds the fasteners to a feed tube under pressure. The air pressure in the feed tube delivers the individual fasteners to the inserter with the fastener being positioned between pivotally movable head fingers which open to receive the fastener to position the same for subsequent insertion and which pivot to enable the fastener to be driven outwardly therefrom by a piston rod so that the fastener is driven into and through the material being secured.
Abstract:
A cat entertainment box including a box with a front face, a left face, a right face, and a rear face, a top. The edges of the top and floor and four faces are coupled together at their edges to form an integral rectilinear configuration. A hole is located in the top adjacent to the front face and essentially spaced from the side faces with indicia on the top with a top hole. The top hole allows entrance and egress of a cat into and out of the box. A design is on the front face, left face, right face and rear face. An aperture is formed in the front, left and right faces centrally located between the adjacent side edges and closer to the top edge than the bottom edge.
Abstract:
A method and apparatus for management of application programs in a computer network are disclosed. A modified hierarchical database which includes application objects that represent applications and their execution environments is utilized. Administrator tools support the creation, deletion, and modification of application objects. Each application object includes the location of an executable code for a given application, an icon, a working directory name, drive mappings, printer port captures, command line parameters, and similar information. An application launcher queries the database and updates a list of available applications which is kept in the user's desktop. The launcher automatically launches specified applications when a user runs the launcher. The launcher also uses the information in the application object to setup resources needed by the application, to create a process that executes the application, and to clean up after the application terminates. Resource setup involves mapping drives and capturing printer ports as needed. The database, the launcher, and the administrator tools allow consistent tracking and use of information about application programs and their execution environments in the network.
Abstract:
An audio surround-sound system includes a main enclosure, an audio decoder device to decode audio source signals supplied by an audio source device to provide decoded audio signals, and at least a first and second low distortion amplifier housed within the main enclosure to receive and amplify the decoded audio signals. Also included is at least a first and a second speaker element operatively coupled to the at least first and second amplifiers, respectively, to produce the audible signals, where the audible signals are received by the listener from a first and second direction. A local radio transmitter converts a portion of the decoded audio signals into radio modulated signals and transmits the radio modulated signals where a wireless receiver receives and converts the radio modulated signals into remote audio source signals. A third speaker element produces audible signals to be received by the listener from a third direction, where the third speaker element is operatively coupled to a third low distortion amplifier. The third low distortion amplifier receives and amplifies the remote audio source signals, where the third low distortion amplifier, the wireless receiver and the third speaker element are remotely located from the main enclosure. The audible signals received by the listener from the first, second, and third directions operatively surround the listener with the audible signals.
Abstract:
A dual suction device includes an enclosed housing with a hollow interior cavity and an exhaust port formed in a rearward wall of the housing. A suction tube is pivotally mounted to the housing to pivot between a first position communicating with the exhaust port, and a second position sealed from the exhaust port. A tubular arm is also connected to the housing and fluidly connected to the interior cavity. A flap on the suction tube is moved in conjunction with pivotal motion of the suction tube to selectively alternate suction from the exhaust port between the tubular arm, when the suction tube is in the second position, and the suction tube, when the suction tube is in the first position.
Abstract:
A three-dimensional electrode device is disclosed. The device is useful as a neuron interface or as a cortical implant. A plurality of spire-shaped electrodes, formed of semiconductor material, are associated with a rigid base. The electrodes are electrically isolated from each other at the base. Multiplexing circuitry allows the electrodes to be addressed individually.
Abstract:
Proteins with inhibin activity having a weight of about 32,000 daltons. The molecule is composed of two chains having molecular weights of about 18,000 and about 14,000 daltons, respectively, which are bound together by disulfide bonding. The 18K chain is obtained from the human inhibin gene and has the formula: H-Ser-Thr-Pro-Leu-Met-Ser-Trp-Pro-Trp-Ser-Pro-Ser-Ala-Leu-Arg-Leu-Leu-Gln-Arg-Pro-Pro-Glu-Glu-Pro-Ala-Ala-His-Ala-Asn-Cys-His-Arg-Val-Ala-Leu-Asn-Ile-Ser-Phe-Gln-Glu-Leu-Gly-Trp-Glu-Arg-Trp-Ile-Val-Tyr-Pro-Pro-Ser-Phe-R.sub.65 -Phe-His-Tyr-Cys-His-Gly-Gly-Cys-Gly-Leu-His-Ile-Pro-Pro-Asn-Leu-Ser-Leu-Pro-Val-Pro-Gly-Ala-Pro-Pro-Thr-Pro-Ala-Gln-Pro-Tyr-Ser-Leu-Leu-Pro-Gly-Ala-Gln-Pro-Cys-Cys-Ala-Ala-Leu-Pro-Gly-Thr-Met-Arg-Pro-Leu-His-Val-Arg-Thr-Thr-Ser-Asp-Gly-Gly-Tyr-Ser-P e-Lys-Tyr-Glu-Thr-Val-Pro-Asn-Leu-Leu-Thr-Gln-His-Cys-Ala-Cys-Ile-OH, wherein R.sub.65 is Ile or Arg. The 18K chain is connected by disulfide bonding to the 14K chain.
