Abstract: A container for displaying and transporting a heavy product, such as a vanity top, is fabricated and assembled as an integral unit to secure the product against possible damage while permitting the product to be easily transported and viewed by prospective purchasers. Each of its pair of side wall panels has an elongated central flap section which is hinged and folded inwardly to define a generally front-facing double fold front surface for the container slanted in a front and back direction and elongated in a direction generally transverse to the top and bottom wall panels. An upper end flap hinged along an upper edge of each side wall panel is at least in part folded inwardly in spaced generally parallel relation to the side wall panel, defining a surface extending generally transverse to the top and bottom wall panels to block movement of the product toward the back panel. Central, upper and lower pairs of overlapping rounded tabs are cut in the side wall panels and in the intermediate flap sections.

Abstract: A radio link for a digital radio transmission system having spatial and/or angular diversity is optimized in real time by searching for a minimum of the analog BER function BERn(.phi.), by analyzing the minimum to determine if it is an "absolute" minimum that will result in an optimal radio link, and if not, searching for another minimum until the absolute minimum is located. Once the relative phase .phi. corresponding to the absolute minimum has been thus determined with both channels having the same nominal attenuation level, the relative attenuation level T of the two channels may then be varied in order to optimize the dispersion Ban.sub.n (T) of the recombined data spectrum while holding the relative phase at its previously optimized value.

Abstract: A combined scanning probe and scanning energy microscope, in which the same scanning system is used for both the scanning probe and scanning energy images. A sample is translated substantially along a horizontal plane either between or below the probe of a scanning probe microscope and the objective of a scanning energy microscope. The probe collects topographic or other information. The objective focuses a fixed beam of energy to a small spot on the sample, then collects energy from the same spot and transmits it to a detector. A vertical translator connected to the probe or sample support provides the vertical motion necessary to maintain them in close proximity. The images produced by the two microscopes are in substantial direct registration with each other. The invention is exemplified by a combined atomic force and confocal laser scanning microscope with a translated sample.

Abstract: A process for the immobilization of a linear polymer, in particular a polyionenes, which is soluble in an aqueous solvent, on a chemically inert carrier material and a matrix having an antimicrobial effect are provided, which are suitable for, in particularly intracorporeally applied, medical appliances and in the form of microporous membranes as filters for water purification or, in the form of beads, as a surface disinfectant. The process is characterized in that the two terminal reactive groups of the linear polymer are reacted with an excess of an alpha, omega-bifunctional compound, the reaction product obtained is dissolved in a hydrophilic solvent and applied at least once to the carrier material and then cross-linked with a cross-linking agent dissolved in a hydrophobic solvent which is chemically inert to the cross-linking agent and the carrier material.

Abstract: A torchiere lamp having a base and an upwardly directed general area lighting fixture supported upon a stem extending from the base. A task light is supported upon a rod which passes through a pair of anchors secured to the stem so that the rod is disposed substantially parallel to the stem. One of the anchors carries a locking member in the form of a threaded thumb screw which may be loosened to permit vertical and rotational movement of the rod for positional adjustment of the task light. The task light includes a reflector or shade pivotally attached to the rod to thereby permit further rotational and pivotal adjustment of the reflector.

Abstract: An expandable chamber piston type internal combustion engine operating in an open thermodynamic cycle includes a combustion process having a constant volume (isochoric) phase followed by a constant temperature (isothermal) phase.

Abstract: An integrated compliance electrohydraulic servovalve system connected to a load such as a simulated living being to provide more realistic movement thereto. The system includes a pressure transducer for sensing the pressure appearing at the output of the electrohydraulic servovalve and which is applied to an actuator connected to the load. The pressure as sensed is developed into a corresponding electrical signal which is used as a feed back signal to the drive motor of the electrohydraulic servovalve. The actuator position signal is also provided and is summed with the position command input signal to provide the command signal which is also summed with the pressure signal prior to application to the drive motor. The utilization of the pressure feed back signal provides compliance to the over all system resulting in a realistic movement of the simulated living being.

Abstract: Antenna elements and systems and other radio and microwave frequency devices are constructed with a high index of refraction medium having high matched values of relative permeability and relative permittivity, and a low loss tangent. By making the permeability of the transmission medium substantially equal to its relative permittivity, the impedance of the material is matched to that of the surrounding free space or air. By immersing a radiating element in such a material, and/or by using such a material between adjacent radiating elements or between a radiating element and a reflective ground plane, the physical size and/or the spacing of the elements may be substantially reduced without appreciable performance loss, thereby resulting in a more compact device that is particularly desirable for mobile applications.

Abstract: The invention concerns a cooling system pressure testing device for the purpose of leak detection. The device has a bladder with a passage extending therethrough. The bladder may be inflated to lock it within an opening in an object to be pressure tested and once inflated fluid may be passed through the passage to pressurize the object being tested.

Abstract: The disclosed spread spectrum system has the reference transmitted on one phase (basis vector) of a .pi./2-offset QPSK signal, and the spread data signal transmitted on another phase (basis vector). The two received phases are combined to recover the baseband signal. Such a transmission system is tolerant to multipath dispersion since all delay paths carry an appropriately delayed reference and signal path induced dispersion on the spread data signal is also present on the reference. If one of the two signals is delayed by a predetermined time interval and a corresponding delay is present in each of two cross-coupled signal processing paths following a conventional I-Q demodulator, the resulting two phase quadrature baseband signals may be combined to form a replica of the original baseband signal. The resultant asynchronous demodulation eliminates the usual requirement for carrier lock at the receiver and is therefore tolerant to Doppler shifts and other frequency errors.
