Abstract: Odor absorbing sheet material is formed from a thin flexible substrate sheet on which discrete spaced areas, for example dots, of bonding agent such as latex adhesive are applied. Odor absorbing granules are bonded to the surface of each adhesive area. Since only small portions of the surfaces of the granules adhere to the adhesive, the odor absorbing capacity of the granules is not impaired. A thin flexible permeable cover sheet is applied on the or each granule coated side of the substrate sheet and is attached in a manner which maintains permeability of the assembly so that access of air to the granules is preserved and which does not substantially affect the flexibility of the assembly so that a sheet product with a soft flexibility and drapeable hand is obtained. Preferably, the outer cover sheet of the assembly is an anti-friction porous polymer web such as for example the webs used as facing layers on non-stick or non-adherent wound dressings and bandages.

Title: Modular prefabricated building panels
Inventor: RIDDELL A STEWART
IPC: E04C2/52
Filed: 1992-10-28
Abstract: ABSTRACT          Construction and use of a modular system of prefabricated building panels is described: in the system a structural frame of characteristically OSB (oriented strand board) or plywood is formed in jigs under compression, the integrity of the frame being assured by the rabbeting or dovetailing of all joints and the design of the supporting channels and l-struts, and by the gluing and nailing of all parts. In the preferred embodiment for load-bearing and insulating wall, floor and ceiling panels additional rigidity is provided by fire-retardant expanding foam insulation which hardens under pressure inside the frame. Electrical conduits are pre-set into the frame, which is offset from fastened interior and exterior sheathing boards so that the finished panel will mate in a rabbet joint with an identical panel; thus a series of such panels can be connected in the field with ease. In addition, the exterior sheathing of wall panels extends down to exactly cover the thickness of a joining floor member to prevent thermal loss and wind penetration; and a special comer wall panel has its dimensions reduced by the thickness of a joining wall member, so that the joint can be accommodated without compromising the horizontal modularity of the multiple identical-panel design.

Inventor: BROVKO OLEG
IPC: G01S13/931
Filed: 1993-02-24
Abstract: A maximum likelihood estimator and range-only-initialization target detection method employed to detect and resolve targets in a multislope linear frequency modulated waveform radar.  The method resolves a large number of target returns without a large amount of signals processing and without creating a significant number of false alarms, or ghosts.  The method simultaneously estimates range and doppler for each target.  The method rejects undesired long-range targets that fold into target regions, and processes target regions of interest around a nearest target to reduce signal processing throughput requirements.  Using a K out of N detection rule, the method detects targets that compete with mainlobe rain clutter, mainlobe ground clutter, and receiver leakage.  The method simultaneously estimates target parameters and optimally resolves any number of targets.  The  method is limited only by the number of frequency modulation ranging slopes, the slope values, and the doppler filter resolution set by the radar waveform design.  The method has the ability to process and detect extended targets. Uses include in automotive cruise control, collision warning systems and airborne radar.

Title: Frequency counter and method of counting frequency of a signal to minimize effects of duty cycle modulation
Inventor: HULSING RAND H II
IPC: G01P3/489
Filed: 1991-09-04
Abstract: A dual-edge frequency counter and method for minimizing the effects of duty cycle modulation. In its simplest form, a dual-edge counter (50) includes a first counter (52) that accumulates reference clock pulses between successive rising edges of an input signal. An input signal is also applied to an inverter (54), which inverts the square wave signal prior to applying it to a second counter (56) that also accumulates reference clock cycles between successive rising edges of the inverted sensor signal. A summation junction (60) totals the accumulated counts from the first and second counters so that they can be averaged by a divider (62), which divides the total count by two. The technique is also employed in connection with a frequency counter that includes an integer counter (72) for totaling the number of cycles of the sensor signal occurring during a sample time defined by successive gate signals.

Abstract: Procedure for the production of a thixotropic magnesium alloy by adding a grain refiner combined with controlled, rapid solidification with subsequent heating to the two-phase area. It is preferable to use a solidification rate of > 1<o>C/s , preferably >10<o>C/s. It is essential that the solidification takes place at such a speed that growth of dendrites is avoided. Heating to the two-phase area is carried out rapidly in 1-30 minutes, preferably 2-5 minutes. By heating an alloy comprising 2-8 weight % Zn, 1.5-5 weight % RE, 0.2-0.8 weight % Zr balanced with magnesium to a temperature in the two-phase area after casting, the structure will assume a form in which the  alpha -phase is globular (RE = rare earth metal). The size of the spheres will be dependent on the temperature and the holding time at that temperature and they will be surrounded by a low-smelting matrix. It is preferable that the alloy has a grain size of < 100 mu m, preferably 50-100  mu m. A grain-refined magnesium alloy comprising 6-12 weight % Al, 0-4 weight % Zn and 0-0.3 weight % Mn also assumes thixotropic properties when heated to the two-phase area. Grain refiners such as Zr or carbon-based agents such as, for example, wax/fluorspar/ carbon powder or calcium cyanamide can be used, depending on the alloy. <IMAGE>
