Abstract: The present invention refers to a supplementary unit for a travelling fork lift truck used for picking up platelike mounting elements. The platelike mounting elements are picked up by a pick-up means of the supplementary unit, said pick-up means being secured to a frame via a carrier arm and a guide rod. The frame is adapted to be lifted by the forks of the fork lift truck. When the carrier arm is pivoted through an angle of 90.degree., the pick-up means, which is guided by the guide rod, will be turned through an angle of 180.degree.. The pivoting movement of the carrier arm is carried out by a hydraulic lifting cylinder.

Abstract: A removable projectile magazine for paintball guns has a cylindrical, spring loaded housing with an opening at one end for receiving and ejecting paintballs. The end also has a one-way valve consisting of a plurality of flexible fingers subtending a hemispherical shape. The fingers permit insertion of paintballs into the housing but prohibit removal of the paintballs therefrom when the housing is not received on a gun. When received on paintball gun, a de-activating member forces the resilient fingers apart allowing the paintballs to exit from the housing.

Abstract: A method and apparatus for inspecting integrated circuit probe cards in which the probe points of the probe card are scanned across a checkplate having a conductivity transition border. The impedances between the probe points and the checkplate as they cross the conductivity transition border are measured to determine when the probe points cross the border. The positions of the probe card when each of the probe points crosses the border are measured to determine the positions of the probe points relative to each other. In one embodiment, the checkplate is formed by a square conductive plate having three quadrants of insulated material and a single quadrant of conductive material mounted on its upper surface. These conductive strips connected to the conductive plate are positioned between the quadrants of insulative material to form the conductivity transition border. In other embodiments, multiple parallel strips or a single dot of conductive material are surrounded by insulative material.

Both the napkin and the panty liner employ a centrally located mounting device which is not connected to the fluid imperiable layer.

Abstract: An E-field sensing apparatus detects the energization of high voltage utility transmission and distribution lines. An external housing substantially shields internal components of the apparatus from the detected E-field. A conductive wire extends from the housing where it is exposed to the E-field. A signal is induced onto the exposed wire and sensed by the apparatus. The length of exposed wire and the distance of the apparatus from the high voltage line attenuate the E-field so the induced signal is within operational parameters of internal sensing components. Adjustments to the wire length and apparatus distance enable detection of E-fields surrounding power lines carrying voltage levels of a predetermined voltage level (i.e. approximately 2000 volts and higher). In response to the E-field the apparatus generates an analog output signal and a line isolation control (one-bit digital) signal. The analog output signal drives a meter, LED or other indicating device serving to aid maintenance engineers.

Abstract: A novel fixture (8) for securing personal computers has a tether cable (10) connected to a loop portion (13) which is in turn connected to an expansion slot cover plate (12) for a personal computer. Once the fixture (8) is installed in an expansion slot opening (15) of a personal computer, the computer is secured if the tether cable (10) is attached to a fixed location such as a table (16) using a padlock (17).

Abstract: A semiautomatic pneumatic gun is provided incorporating a reciprocatable striker-barrel which performs the normal functions of a barrel and a striker, sliding during firing from a cocked position in response to the urging of a striker power spring to impact upon a normally closed valve, which impact releases compressed gas for propelling a projectile from the gun and for recocking the gun. A slidable bolt serves to transfer the impact of the striker-barrel to the valve, and functions as a piston moving in a cylindrical recocking chamber in response to the urging of gas released by the valve to move the striker-barrel back to the cocked position.

Abstract: A safety cane incorporates an ambient light sensitive illumination device for conserving battery power. A tipping detector is also incorporated which sounds an audible alarm after a first time delay. If the cane is not retrieved by the end of the second time delay, the cane broadcasts an initiating instruction to a telephone dialing device.

Abstract: A rapid deployment system for recovering oil from beachers includes an articulated vehicle for propelling and suspending a vacuum head above a beach or the like. A selected area of the beach is irrigated with sufficient quantities of water to saturate the selected area. Oil deposited on the beach is driven to the surface. A sufficient quantity and velocity of air moves over the surface beneath the vacuum head to develop a water column upon which resides a frothy foam mixture of air, water and oil which is drawn into the head. In the vacuum head, the velocity of the air flow is suddenly and significantly reduced above a fluid sump wherein entrained oil and water droplets fall into a sump for processing outside of the vacuum head. A metal auger can be provided within the vacuum head to pump oil from pools and separate entrained oil droplets from the high velocity air flow. A special terrain vehicle which propels and supports the vacuum head is modular and can be transported by helicopter with the entire system.

Abstract: An electrical muscle stimulator converts electromyographic (EMG) signals to digital words for analysis and display by a computer program. The therapist selects a variety of different parameters appropriate for the individual patient, and instructs the device to initiate stimulating signals on command, or upon detection of a suitable EMG signal from the patient. The device that converts digital words representing the selected parameters into complex, bipolar therapeutic pulses. The device can digitally model a wide variety of wave forms and graphically assist the therapist in developing and shaping various wave pulse trains.

Abstract: A thin film membrane filtration system recovers particulate from the waste water stream of a wood panel fabrication process to a desired concentration of approximately 30-50% solid by weight. The high concentration level enables improved transport or disposal. Rather than discard the concentrate, however, the concentrate is added into subsequent wood panel "particle board" batches at a rate of approximately 0.5 to 0.65 gallons per 1000 pounds of wood product. The concentrate reduces press time, serves as a scavenger for tying up formaldehyde and serves as a resin extender for strengthening internal bonds of fabricated panels. The membranes capture the particulate into an accumulated concentrate, while passing permeate output to a recycle water stream.

Abstract: A sunlit world globe provides a realistic and constantly accurate day/night pattern on the surface of the globe. The globe employs an internal, rotating baffle for a light source. The baffle rotates with respect to a semi-transparent shell constituting a planetary model. The shell has an aperture at the bottom so that a motor, fixed to a frame can rotate the baffle through an axle. The shell pivots about a horizontal axis .+-.23.5 degrees to simulate the earth's orbit around the sun. An adjustment mechanism positions the polar axis of the earth with respect to an imaginary, ecliptic plane appropriately for the current time of year. In an alternate embodiment, the globe rotates with respect to the frame. The frame carries an arch having a day/night demarcation.
