This relates to a carton for packaging a product which is to be processed in a microwave. The carton includes a top wall which is hinged to a portion of a rear wall and has a glue flap bonded to a removable portion of a front wall. The carton is formed of a delaminatable web with the top wall having transversely spaced score lines in opposite faces thereof whereby the carton is openable by removing the removable portion of the front wall and then peeling a major portion of the top wall from border portions thereof to open the carton. After the product has been removed, the top wall is swingable into the interior of the carton to form a support platform for the product. The support platform is positioned a predetermined distance above the bottom wall of the carton to provide for a maximum efficiency of the heating of the product within a microwave oven.

Synthetic aperture radar data is used in conjunction with altimeter data to produce a terrain map corrected for platform roll angle. The technique uses two synthetic radar antennas and a ranging altimeter placed on an aircraft. The aircraft is moved in a set of substantially parallel flight paths where each flight is directly over the strip of terrain viewed by the synthetic aperture radar of an adjacent flight. During each flight the at least one antenna repeatedly transmits radar signals whose return echoes are received by both the first and second antennas. Conventional synthetic aperture radar processing yields a terrain map uncorrected for roll angle. Altimeter data from an adjacent flight determines the first order corrected aircraft roll angle when the corresponding synthetic radar data was taken. This roll angle is used to correct the height and ground range of nearby points in the uncorrected terrain map. A second order corrected roll angle is determined using the first order corrected terrain map to identify the first return point of the altimeter measurements. The measured altitude is then realigned to the first return point to produce a second order corrected roll angle and a corresponding second order corrected terrain map. The result is a terrain map corrected for aircraft roll angle.

A tray-type container for processing and marketing a loaf of bread, or the like, and a method of forming the same is disclosed, which tray is formed from a single blank of paperboard having a coating of a heat sealable and heat resistant film material so as to provide, when fully set-up, a rectangular bottom wall with hingedly connected upstanding sidewalls integrally connected at the corners by pairs of triangular web members folded upon each other and against the outside faces of opposite sidewalls where they are secured in reinforcing relation by narrow top edge flanges folded into underlying relation with and sealed to narrow flanges at the top edge of the sidewalls with the film material being skip-cut at the top edge of the sidewalls so as to reduce buckling in the sidewalls which otherwise results due to the difference in shrinkage of the film and the paperboard material.

A lamp assembly having a gravity-actuated switch which is adapted to be mounted to the underside of a hinged cover member of a vehicle to illuminate a compartment of the vehicle when the hinged member is opened to a predetermined extent. The lamp assembly has a housing, a lamp disposed in the housing, first conductor means for electrically interconnecting a first electrical terminal with one terminal of the lamp, second conductor means for electrically interconnecting a second electrical terminal with a first contact point, and third conductor means for electrically interconnecting the other terminal of the lamp with a second contact point. The assembly has a switch for automatically turning on the lamp when the housing is moved to a first angular orientation and turning off the lamp when the housing is moved to a second angular orientation. The switch has a slidable member with a conductive portion, the slidable member being movable between a first position in which the conductive portion of the slidable member electrically interconnects the first and second contact points and a second position in which the first and second contact points are electrically isolated. The assembly may have an inverted pivot member, movable under the influence of gravity, for causing the slidable member to occupy the first position when the housing is in the first angular orientation and for causing the slidable member to occupy the second position when the housing is in the second angular orientation.

A process for removing carboxylic acids from aqueous solutions using a composition of a polyaluminum chlorohydrate and a cationic polyelectrolyte is described. After or during the initial contact of the aqueous solution with the composition, an organic liquid may optionally be added after which separation into an aqueous phase and an organic phase occurs whereby the organic acids are removed in the organic phase. The preferred polyaluminum chlorohydrate is aluminum chlorohydrate, and the preferred cationic polyelectrolyte is a high molecular weight poly(dimethyl diallyl) ammonium chloride.

Synthetic aperture radar data is used in conjunction with altimeter data to produce a terrain map corrected for platform roll angle. The technique uses two synthetic radar antennas and a ranging altimeter placed on an aircraft. The aircraft is moved in a set of substantially parallel flight paths where each flight is directly over the strip of terrain viewed by the synthetic aperture radar of an adjacent flight. During each flight the at least one antenna repeatedly transmits radar signals whose return echoes are received by both the first and second antennas. Conventional synthetic aperture radar processing yields a terrain map uncorrected for roll angle. The uncorrected terrain map data from one flight are compared with the altimeter data taken during an adjacent flight. This permits the altimeter data to be used to determine the roll angle when the corresponding synthetic radar data was taken. This roll angle measure is then used to correct the height and ground range of nearby points in the uncorrected terrain map. The result is a terrain map corrected for roll angle in a manner more accurate than can be obtained by direct measurement of the roll angle.

This relates to a clasp lock for interlocking two overlapping closure panels of a carton. The clasp lock is made adjustable to compensate for different sizes of articles being packaged in the same carton. In order to effect the adjustment of the lock between the closure panels, the primary locking tab is of a stepped height and the closure panel carrying the primary locking shoulders is cut so that the primary locking shoulders are also stepped with respect to the free edge of the associated closure panel. In the interlocking of the closure panel portions, the primary locking tab will automatically engage the proper primary locking shoulder in accordance with the objects which are being packaged within the carton.
