In one embodiment of the present invention, the slats secured to the exterior surface of the vehicle extend transversely, rather than longitudinally of the vehicle, and the article constraining bars or rails extend longitudinally of the vehicle.  The cross-bars or rails may have attachment means thereon for securing ancillary article carrying equipment, such as ski racks, bike racks, and the like to the carrier system.

Abstract: ABSTRACT (OF THE DISCLOSURE) "IDEOGRAPHIC CHARACTER ENCODING"      A character selection keyboard for use in connection with an ideographic language of which the characters can each comprise one or more of a set of character components, as defined.  The keyboard comprises an array of character component keys each bearing a symbol corresponding to a character component.  Some of the components have separate linguistic identity and can accordingly be used in isolation to constitute characters in the ideographic language;  these components are all depicted within a part of the array which is visually didtinct from the rest of the keyboard.  The keyboard can be connected in a composing system in which data defining the structure of the characters constituted by the components selected by key actuation is derived from a programmable store in response to key signals generated by the key actuation.          The keyboard may also be used in typewriters, telex machines, and other systems requiring data input.

Abstract: TWO-PIECE SEAL FOR TRACK CHAIN JOINTS              Abstract of the Disclosure A sealed joint assembly interconnecting links of crawler tractor track chain includes an annular sealing member made of relatively rigid abrasion resistant material formed to define contiguous axially and radially extending bands, the sealing member thus being generally right angular in cross section.  The radially extending band includes a pair of surfaces which converge axially to form an annular edge which engages an end surface of a track bushing and is in fact biased theretowards by means of an annular compressive load member made of resilient relatively pliant material of generally rectangular cross section loaded predominantly in compression between the bottom of a counterbore of one of the links and the sealing member.  A spacer ring is located radially inwardly of the axially extending band of the sealing member and augments the band in restraining radially in-ward expansion of the load member.

Abstract: Abstract of the Disclosure A frequency divider is known which uses varactor diodes in a circuit which resonates at fo/N where N is an even integer.  Because of circuit losses within the varactor diodes, amplifiers are generally required to recover the input signal level.  For systems that require cascaded frequency dividers at least one amplifier is required for each frequency divider.  The present invention overcomes these problems by providing a microwave frequency divider to perform parametric frequency division and amplification simultaneously at microwave frequencies.          A signal fo is applied to an input transmission line which forms, with the inherent frequency dependent non-linear gate-to-source capacitance of at least one MESFET, a circuit resonant at fo/N, wherein N is an even integer such as 2.  The source-drain path of the MESFET is coupled via an output transmission line to a balun transformer having an output to provide amplified signals at fo/N.  The transmission lines may be microstrip, stripline or other suitable type of transmission line.

Abstract: "CONTINUOUS CASTING MOLD ASSEMBLY"   U.S. Ser No. 958,774 ABSTRACT   Disclosed is a mold assembly characterized by efficient and controlled removal of heat from molten metal during continuous casting, providing high casting speeds in conjunction with superior surface finish on the cast product. The mold assembly includes a refractory mold body having a longitudinal solidification chamber therein and a plurality of longitudinal cooling bores spaced around the solidification chamber.  The cooling bores extend only partially through the mold body in the direction of the solidification chamber to define an insulating section adjacent the inlet end thereof to minimize heat removal from the molten metal source and a cooling section adjacent the outlet end when cooling probes containing a circulating coolant are inserted into the cooling bores.  The cooling probes are adjustable along the length of the cooling bores to accurately control the position of the solidification front in the solidification chamber and provide optimum heat transfer from the molten metal for rapid solidification with superior surface finish. In a preferred embodiment, the mold assembly includes a longitudinal bore defining  a plurality of solidification chambers of increasing diameter in the direction of the outlet end for producing two or more diameters of cast product by positioning the solidification front first in one chamber and then another by suitable adjustment of the cooling probes.

Abstract: SCRUBBER BYPASS SYSTEM            Abstract of the Disclosure A scrubber bypass damper comprises a plate pivotally-mounted to a shaft running across the bypass duct transverse to gas flow.  The damper plate self-actuates and rotates about the shaft in response to any pressure differential established across it.  A scrubber booster fan is disposed in the main flue at a location downstream of the scrubber and upstream of the outlet of the scrubber bypass into the main flue.  When the scrubber is in operation, the pressure rise imparted to the flue gas by the scrubber booster fan is adjusted to keep the damper plate disposed transverse to gas flow through the bypass duct thereby preventing gas flow therethrough.  When the scrubber is taken out-of-service, the booster fan is shutdown and the damper plate self-actuates, opening in response to pressure forces exerted on it by the induced draft fan, thus preventing over-pressurization of the furnace.

Abstract: SAMPLER AND CELL FOR RADON DETECTORS AND METHOD OF USING SAME     ABSTRACT OF THE DISCLOSURE  A relatively small diameter, relatively deep hole is made in the ground and a sampler tube is inserted there-in.  An acetate sleeve is detachably inserted into a cham-ber on the upper end of the sampling tube and the sampler is left for at least sixteen hours and preferably longer in order to permit radon gas to migrate up the tube.  Daugh-ter products of radon deposit on the acetate film which is then placed in a scintillation cell attached to the count-ing chamber of a scintillation counter, which counts the alpha emissions of the daughter products thereby permitting the amount of radon gas to be calculated.  This method redu-ces considerably any contamination of the  scintillation counting chamber so that cleansing is not necessary thus permitting a much higher level of productivity.  The system is also totally insensitive to thoron so that no correction for thoron signals is required.  The same method can be used to collect airborne samples by hanging the acetate strip in a desired location for at least four hours and countaing al-pha emissions from said strip as above.
