Abstract: SOLID IMPURITY DETECTOR                    Abstract of the Disclosure A device is provided for detecting the presence of solid im-purities within a pressurized fluid.  The device-comprises a housing having a fluid passageway formed therein.  One end of the fluid passage-way is open to the pressurized fluid, preferably via a restricted port, while the other end of the fluid passageway is open to a low pressure fluid region.  A filter element is disposed across and obstructs the fluid flow through the passageway at a point intermediate its ends so that the filter element removes solid particles from fluid flowing through the passageway.  A pressure sensing means, such as a pressure transducer, communicates with the fluid passageway between the pres-surized fluid and the filter element.  An increase of fluid pressure sensed by the pressure sensing means is indicative of a clogged filter element which, in turn, indicates the presence of solid impurities within the pressurized fluid.  Appropriate indicating means are coupled to the pressure sensing means  to provide a signal upon the occurrence of the aforementioned increase of fluid pressure.

Abstract: RADAR ALTIMETER SIMULATOR              ABSTRACT OF THE DISCLOSURE         An altitude simulator for checking the range accuracy of a radar altimeter is disclosed.  Typical alti-meters include a transmitter and a receiver.  The simulator receives a multipulse trigger signal from the altimeter to be checked.  The trigger signal is synchronized with the output pulses of the transmitter.  This trigger signal forms an input to a phased locked loop to generate at the output of the phased locked loop a multipulse signal which is synchronized with and phase displaced from the trigger signal by an amount equal to the inherent time delays in the simulator.  The output signal of the phase locked loop is coupled to the input of a pulse generator which is program-mable to generate a multipulse output signal synchronized with and phase displaced from the output signal of the phase locked loop by a selected fixed amount.  A modulator receives an RF input from a signal generator and the output signal of the pulse generator to produce at the output of the modulator, a pulse modulated RF signal.  This pulse modulated RF signal is coupled to the receiver as an input signal and is used to test and calibrate the altimeter.

Abstract: METHOD OF PACKAGING PLASTIC LAMINATE WALL COVER    Abstract of the Disclosure A single sheet of standard grade plastic laminate material is bent at two locations to form it into a side wall and two end walls corresponding to the side wall and two end walls of a bathtub recess.  Following forming, one end wall portion of the wall covering is loosely folded over the opposite end wall portion.  Then, the partially folded wall covering is pushed endwise into a rectangular cardboard box having a normal thickness which is substantially smaller than the initial depth of the partially folded wall covering.  The box with the partially folded wall covering inside is moved through a rectangular opening provided in a rigid mandril, sized to be substantially equal to the normal outside dimension of the box.  The mandril forces the outwardly bulging side walls of the box inwardly and reshapes both the side walls of the box and the side and end walls of the partially folded wall covering therein.  In so doing, the end walls of the wall covering are slid in position an amount sufficient to cause the side and partially overlapped end walls of the wall covering to bow inwardly until the wall covering has assumed a new configuration which is substantially within the normal rectangular shape of the box.  The frictional contact between the backing layer of the wall covering and inner surface portions of the box in contact therewith serve to hold the wall covering in such new configuration, so that the box will retain a substantially rectangular shape.

Abstract: ABSTRACT OF THE DISCLOSURE         A grab excavator comprises a fixed jib mounted on said pontoon, and a grab suspended from the jib for vertical movement, whereby the grab can be lowered below the pontoon for lifting a mixture of sand and water and thereafter elevated above the pontoon for releasing the mixture.  A chute mounted on the jib is pivotal between an inclined operative position beneath the grab and an inoperative position out of the path of the grab, and a feed device is located at the lower end of the chute, when the chute is disposed in the inclined opera-tive position, for receiving the sand-water mixture therein as directed thereto by the chute.  A hydraulic ram mounted on the pontoon pivots the chute between the operative and inoperative positions. The feed device includes a sieve that normally is located in a downwardly inclined position adjacent the chute and at substantially the same angle of inclination as the chute to form an extension of the chute when the chute is located in the operative position, whereby the sieve receives the sand-water mixture from the chute for processing through the feed device.  An opening formed in the feed device in a wall thereof facing the chute receives the mixture of sand and water from the chute as the chute is being raised to the full operative inclined position, thereby preventing loss of fine sand that may escape from the grab before the chute is fully raised to the operative position thereof.
