Abstract: As an effective means for carrying a plurality of record discs for selective reproduction, comprising an index carrier which is formed mainly as an index proper of flexible or rigid lengthy plate or as a series of plates connected with hinges, the periphery of the index proper having notches acting as indexing points for fixing and indexing the desired record disc and the side periphery or peripheries acting to restrain and guide the index carrier in a specific and regular direction. A simplified sound reproducing device for using aforesaid index carrier is constructed, in addition to ordinary means such as a tone arm, a turn table, a record disc, a sound transmitting member, starting and terminating means and the like, to have an index carrier magazine composed of a pair of magazines each disposed at each transverse side of the casing and having several means such as a spool, a knob or the like, for feeding the index carrier to the position where it can engage the reproducing stylus of the tone arm.

Abstract: The invention is a backlight assembly which attaches to the roof section to form a convertible top of a vehicle when the roof and the assembly are both in the raised positions. The backlight assembly and the roof section have independent linkage mechanisms which allow each to be positioned independent of the other. The predetermined path of the backlight panel as defined by the linkage mechanism and the guideframe combines both rotational and sliding movements. This is accomplished by initially radically rotating the panel in a counterclockwise manner and then moving the panel along a substantially horizontal plane. When the backlight panel reaches the extreme rearward portion of the guidetracks, the panel is situated in a substantially horizontal position beneath the rear decklid.

Abstract: This new catheter minimizes the exposure of attendant personnel to contaminated materials. The catheter enables the withdrawal of the catheter from the patient and subsequent disposal thereof in a safe, easy to perform, and sanitary manner. The catheter includes a hollow tube made of a material that is inflatable and nonporous. A main passage is located within the tube and extends throughout the tube, from an open end of the tube and through an aperture located near a closed end of the tube. An inlet channel is attached to the tube and is in fluid communication with a chamber adjacent to the aperture. Prior to removing the catheter from the body of the patient, a fluid is injected through the channel and into the chamber, thereby inflating the inner surface wall of the tube, and essentially blocking the main passage. The closed chamber is secured to prevent the release of the injected fluid.

Abstract: This is a new apparatus and method for cleaning debris from the inside of a foundation drain tile, the drain tile being in the immediate proximity of the perimeter of a building structure. A rocket nozzle which is in fluid communication with flexible tubing and a high pressure water supply, and a foot pedal control valve is used for starting and stopping the fluid flow. An opening in the tip of the nozzle enables pressurized water to be discharged through the tip in a forward direction. At least two apertures are disposed along a nozzle recess. The tubing is secured to the nozzle and is in fluid communication with the nozzle. An on-off foot pedal control valve is used to start and stop the water flow into the tubing and into the nozzle. As pressurized water is supplied to the nozzle and projected through the apertures, the nozzle is propelled in a forward direction through the drain tile.

Abstract: A teartape for packaging materials, and particularly such materials based on polyolefin films, includes a base film coated with a pressure sensitive adhesive composition. The teartape is affixed to the packaging material by the adhesive composition. This avoids the problem of distortion which can occur when affixing conventional teartapes to such packaging materials by means of hot melt wax compositions. The teartape is applied to moving packaging material by controlling the speed of the teartape in accordance with the speed of the packaging material so as to reduce tension imbalance. The speed of the teartape may be controlled in dependence upon the tension in the teartape. This can be achieved by supplying the teartape from a dispenser having a brake means (4,5) and a drive means (10,11,12) for regulating the speed of the teartape in dependence on the tension in the teartape.

Abstract: A pressure regulator continuously actuates the relative axial position and the tangential position of an armature relative to a valve body into the desired position so as to deliver a fluid at a constant pressure. The tangential position of the armature is determined in response to an electrical excitation of a coil resulting in a change in the magnetic forces applied to the armature. The axial position of the armature is adjusted in response to changes in the control pressure. The armature has a plurality of ports which enable fluid to enter and leave therefrom. The valve body has a plurality of ports in fluid communication with the armature ports. The armature has two elongated prongs. A compression spring is generally centrally disposed within the electromagnetic compartment of the armature. One end of the spring is secured to the armature and the other end of the spring is secured to the regulator housing.

Abstract: A control apparatus for a sliding vehicle mounted roof panel controls the movement of the sliding roof panel between fully opened and fully closed positions within a window opening in the vehicle and predetermined intermediate, partially opened positions. The control apparatus includes a sensor for detecting the position of the sliding roof panel and a control apparatus, responsive to the output from the sensor, for activating or de-activating the drive motor controlling the movement of the sliding roof panel. A plurality of sensors may be spaced longitudinally along the longitudinal edge of the roof opening to provide a plurality of intermediate, partially opened stop positions for the sliding roof panel between the fully opened and fully closed positions.

Abstract: A plurality of record discs are carried on a single rotatable indexing table detachably mounted on the casing of the device, any one of which record discs can be brought into engagement with a turn table carrying a pickup. On the casing, there are provided a starting rod and a member for terminating reproduction upon arrival of the pickup of the tone arm at the end point of sound reproduction.

Abstract: The laser resonator of the present invention has multiply folded optical paths in an extended region by utilizing a set of front surface reflecting elements. The resonator can be used in a gas laser oscillator or amplifier, in either continuous wave mode or pulsed mode. This optical path is folded into larger domains within a polygonal area of the laser cavity, thereby achieving increasingly longer laser paths without a corresponding increase in the number of folding elements. The resulting domains fully cover the plane with a grid of evenly spaced and intersecting optical paths. In one embodiment, the invention consists of a waveguide gas laser system with a ceramic block having a multiply folded optical path of intersecting waveguide channels cut into the block. The reflecting mirrors of the laser resonator are integrally attached to the ceramic block, enhancing the durability of the laser resonator and reducing the size.

Abstract: Described herein is an acoustic degasification process for separating dissolved gases from hydropressured or geopressured liquids. The liquid and the dissolved gas flow through a hollow chamber that is vibrated utilizing acoustic energy so as to focus the acoustic energy near the center of the hollow chamber, and by the process of rectified diffusion bubbles form and grow within the liquid, wherein buoyancy forces cause the enlarging bubbles to migrate to the surface of the liquid.
