Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for digital time-variant filtering are disclosed.  The digital time-variant filters are implemented using the Hilbert transform and a time-varying instantaneous frequency control function for cont-rolling the cutoff frequency.  The digital time-variant filters are adaptable to various filtering processes, that is, as either a high-cut, low-cut, band-pass, or reject filter.  The various digital time-variant filters are stable in that no unusual transients occur in the output signal; are flexible in that the cutoff frequency is cont-rolled by a selectable time-varying control function signal; and are efficient in that computational require-ments are only twice to 16 times that of known digital time-invariant filters.

Title: Shipping container for electronic components
Inventor: SARVER PAUL H
IPC: B65D25/06
Filed: 1983-12-19
Granted: 1987-10-20
Abstract: Abstract A shipping container for electronic components includes first and second container portions.  The second container portion is designed for engagement by the first container portion either as a lid or in nested configuration to minimize the vertical height of the two container portions for empty shipping and storage.  The first container portion includes grooved interior side walls and partitions engage able in the grooves to reduce the interior size of the first container portion according to the dictates of the component to be shipped.  The interior partitions include layers of resilient foam material which form fit to surface features of the component being shipped.  The exterior of the first container portion is grooved to provide handgrips, and one pair of opposed walls of the first container portion extends below the level of the container floor to provide feet for stacking multiple containers, to add shock-absorbing capacity to the container, and to provide a recess within which to engage a hand truck.  The second, or upper, container portion includes a peremptorily flange extending outward from the side wall to stop the projection of the second container portion into the first, both when the second container portion is serving as a lid (right-side up orientation), and when the container portions are assembled empty for shipping and storage (upside-down orientation).

Abstract: APPLICANTS:   DIAB-BARRACUDA AB          TITLE:       THERMAL CAMOUFLAGE              ABSTRACT OF THE DISCLOSURE        A thermal camouflage comprises a strengthening layer such as a woven material, on which a polyethylene film layer, metallized on one side, has been laminated with the aid of fusion adhesive.  On lamination the surface is embossed such as to make it mat. Since the polyethylene is transparent for infrared, it has low self-radiation. By means of the metal layer, there is obtained radiation insulation so that the outer layer is in a thermal equilibrium which is hardly affected, e.g. by a warm object which is covered with the material, and the outer layer has a low emission ability of about 0.6-0.8, depending on thickness and pigmentation.          By applying further layers, patchy images may be obtained with infrared reproduction in the wavelength ranges of 3-5 µm and 8-14 µm

Abstract: NEGATIVE CLIMB AFTER TAKE-OFF WARNING SYSTEM          Abstract of the Disclosure A warning system for aircraft compares the rate of descent of the aircraft with its altitude above ground after take-off, and generates a warning if the aircraft is experiencing an excessive descent condition for the radio altitude at which the air-craft is flying.  The position of the landing gear, the speed of the aircraft and the engine power are monitored to enable the system only during the take-off or missed approach phases of operation in order to minimize false warnings during other phases.  The relationship between radio altitude and descent rate required to generate a warning is optimized for small, high performance aircraft such as fighter or attack aircraft.

Abstract: BRAKE MECHANISM Abstract of the Disclosure A park brake mechanism includes a sealed housing enclosing a brake disc pack which is normally pressed together by a plurality of coil compression springs acting between an end of the housing and a pressure plate.  Four hydraulic pistons are reciprocably mounted in the opposite end of the housing and connecting pins are received between the pistons and the pressure plate and serve to effect the release of the braking action between the disc pack discs when the pistons are pressurized.  The pistons are in a rectangular pattern and diagonally opposite ones have threaded ports aligned therewith and adapted for receiving screws for stroking the pistons in the absence of pressure.  A fluid pressure passage leading to the pistons contains a one-way orifice which operates to modulate the application of the brakes when pressure is relieved from the pistons.

The detergent(s) perferably is/are a sulfated higher fatty alcohol ethoxylate and/or a condensation product of ethylene oxide and a higher fatty alcohol, and the polyacetal carboxylate is a sodium carboxylate.  The compositions are especially useful for cold water washing of laundry and in such washing processes they are found to be superior in soil and stain removal to similar compositions wherein the polyacetal carboxylate is of higher molecular weight.  They are also superior in such performance to control compositions in which sodium tripolyphosphate is present instead of the polyacetal carboxylate builder.  Also within the invention are washing processes in which the described compositions or essential detersive and builder components thereof are employed.
