Filed: 1991-03-15
Abstract: COMPREHENSIVE WATER TREATMENT SYSTEM               ABSTRACT OF THE DISCLOSURE      In its broadest aspects, a method for the cyclic regeneration of a water system is disclosed. The water softening system comprises an exchange medium in a tank which is in fluid communication with a brine storage tank. This method comprises the steps of filling the brine storage tank with refill NO.2 of softened water in a quantity sufficient to create sufficient brine for said exchange medium, said brine storage tank already containing refill NO.1 of softened water from a later step of the method. The exchange medium is subjected to backwashing NO.1 with water flowing counter the direction of water flowing therethrough during water softening operations. Next, brine from the brine storage tank is passed through the exchange medium. Water then is passed through the brine exchange tank. The exchange medium thereafter is subjected to backwashing NO.2 with water flowing counter to the direction of water flowing therethrough during the water softening operation. Finally, the brine tank is refilled with refill NO.1 of softened water to create brine in quantity insufficient for completely brining the exchange medium.

Title: Biased check rail lock
Inventor: PILTINGSRUD STEPHEN M
IPC: E05B15/04
Filed: 1991-08-13
Abstract: BIASED CHECK RAIL LOCK                        ABSTRACT         A window lock has a window sash mounted housing with a cam which is manually pivotable between a locking position engaging a keeper on a second window sash and an open position clear of the keeper.  A bearing post projects from the cam and a spring secured to the housing exerts a biasing force against the post.   The spring is a leaf spring having a first portion bearing against the post when the cam is positioned toward the locking position from the neutral position, and a second portion bearing against the post when the cam is positioned toward the open position from the neutral position.  A curved portion of the spring connects the first and second portions at an angle relative to each other, and bears against the post when the cam is in the neutral position.  The spring biasing force is di-rected substantially toward the cam pivot axis when the cam is in a neutral position between the locking and open posi-tions, and is overcenter toward the open or locking posi-tion when the cam is selectively positioned toward the open or locking position, respectively, from the neutral posi-tion.  The cam pivots substantially 180° between the open and locking positions, and the neutral position is about 70° from the locking position and about 110° from the open position.

IPC: C01B32/336
Filed: 1991-09-05
Abstract: A process is provided for making a modified carbon molecular sieve which is suitable for separating  gases having different adsorption rates on the sieve.  The process involves modifying a starting sieve support having a majority of micropores with an effective pore size of about 4.5 to 20 angstroms, with a two-step process in which the sieve is contacted with two different concentrations of a volatile carbon-containing organic compound, preferably a hydrocarbon.  The concentration of the carbon-containing compound used in the first step is larger than that in the second step, so that the pore openings of the micropores of the support are narrowed successively in two distinct steps without filling the micropores themselves.  The invention also discloses an improved carbon molecular sieve and the separation of gases, such as oxygen from nitrogen, by the use of this improved adsorbent.

Abstract: An adaptive Decision Feedback Equalizer (DFE)  (40) for a digital  cellular  mobile  radio  channel  demodulator  (30) employs a Complex Fast-Kalman Adaptation algorithm (56) to track channel variations  Sensitivity to sample timing jitter is reduced by providing the DFE with fractionally spaced feed-forward taps  (50').   Deficiencies inherent in using a reduced precision implementation are overcome by adding a dither signal to sets of operation  in the algorithm, the dither signal comprising an appropriately selected Gaussian random variable. For small delay spreads of approximately one third of a symbol duration or less, a resulting degradation in Bit Error Rate is avoided by switching the DFE out of the circuit or by reducing the number of taps of the DFE.  For delay spreads of less than 40 microseconds and greater than approximately 10 microseconds, a (2,3)  fractionally spaced DFE provides an adequate compromise between complexity and performance.

Filed: 1992-11-06
Abstract: A tapered camming plug positioned within an expansion shell is threaded onto an upper end portion of an elongated bolt advanced behind a resin cartridge system into a bore hole drilled in a rock formation. A bearing plate is carried on the opposite end of the bolt and abuts the rock formation surrounding the bore hole. The cartridge is ruptured by upward thrust and rotation of the bolt to release the resin components for mixing. The mixed resin flows downwardly in the bore hole into surrounding relation with the camming plug and expansion shell.      The expansion shell includes a plurality of expansion fingers each formed integral at one end portion with a ring end portion of the shell and extending upwardly to a free end portion for outward expansion into engagement with the wall of the bore hole as the camming plug advances downwardly on the bolt after the resin is mixed. The shell ring end portion has a circular opening for receiving the bolt and an outer, non-circular surface forming a wall having areas of non-uniform thickness to increase the area of the annulus between the ring end portion and the wall of the bore hole. The increased area around the ring end portion facilitates the insertion of the expansion shell assembly into the resin by permitting the resin to flow past the shell and the ring end portion and bond the expansion shell and a portion of the bolt to the rock formation within the bore hole.
