IPC: B01D53/04
Filed: 1991-09-17
Abstract: "FOUR PHASE PROCESS FOR CONTROLLING EMISSIONS DURING COLD START OF INTERNAL COMBUSTION ENGINE" A pollutant containing engine exhaust stream is treated upon cold startup by first flowing the engine exhaust stream, which is relatively cool, over an adsorbent zone ¢5! which comprises an adsorbent bed, i.e., a molecular sieve bed, capable of preferentially adsorbing pollutants such as hydrocarbons. This provides a first exhaust stream which is flowed over a primary catalyst ¢7! which converts the pollutants to innocuous compounds and then discharging the resultant treated exhaust stream to the atmosphere. When the adsorbent bed reaches a temperature of 150 to 200.degree.C, the entire engine exhaust stream is completely diverted over the primary catalyst ¢7!. When the inlet temperature tothe primary catalyst ¢7! has reached 350 to 400.degree.C, a minor portion of the engine exhaust stream is diverted over the adsorbent bed to desorb the pollutants adsorbed on the bed and carry them over the primary catalyst where they are converted to innocuous components. After a certain amount of time, the entire engine exhaust stream is again diverted over the primary catalyst ¢7!, thereby isolating the adsorbent bed to minimize deterioration. The adsorbent zone ¢5! may also have a secondary catalyst bed arranged immediately after it.

Abstract: ABSTRACT      A toothbrush case serving both as an original package case and as a permanent storage-travel case has female and male body members with thin resilient PVC plastic walls that overlap at a detented region for manual engagement and disengagement.  The case body members are in a preferred embodiment hollow receptacles defined by four quadrilateral walls and an end wall, with the male member funnelled for ready insertion into the female member.  Detent dimples in two opposing side walls provide a snap-lock position in a region where the two body members overlap so that they may be manually engaged and disengaged by means of the resili-ency characteristic of the walls. This resiliency absorbs impacts and shocks encountered in storage and assures long life without malfunctioning or breaking.

IPC: G01R31/02
Filed: 1991-11-27
Abstract: ABSTRACT            INSULATION MONITOR WITH IMPROVED PRECISION            The processing circuit of the insulation monitor comprises a microprocessor receiving on a first input a signal representative of the DC component, or the component of preset frequency different from the frequency of the mains system to be monitored,  of the voltage applied to the insulation monitor terminals. The microprocessor receives on a second input a signal obtained by making the difference between a measured voltage representative of said voltage component and a preset threshold value  and by multiplying this difference by a multiplication coefficient. When the measured voltage is greater than the threshold value,  the microprocessor uses the signal applied to the second input so as to improve the precision in the higher voltage range.

Abstract: A concrete structure, such as a burial vault, having an integrally bonded thermoplastic resin liner. The liner is a rigid molded product having a bottom wall and side walls and an open top.  A thermosetting resin adhesive is applied to the outer surface of the liner and consists of an epoxy resin system, a solvent for the thermoplastic liner, and a surfactant.  Before the adhesive is fully cured, wet flowable concrete is applied to the adhesive layer.  The solvent acts to solubilize the outer surface of the plastic liner, while the surfactant reduces the hydrophobic characteristics of the adhesive to provide a firmly bonded composite structure.

That is, the core (12) is excited to the saturation region by the oscillation circuit (18) using the detection coil (13) of the magnetic sensor (11) as part of the parallel resonance circuit (15), and an external magnetic field (H) applied to the magnetic sensor (11) is detected on the basis of the amount of change in waveform of an output signal (a) from the oscillation circuit (18).  As a result, the circuit arrangement can be simplified, and a reduction in size and manufacturing cost of the overall apparatus can be realized while maintaining high measurement precision.
