Title: Organic base fertilizer from municipal sewage sludge
Inventor: MARKHAM EARL R
IPC: C05D9/00
Filed: 1992-09-03
Abstract: ORGANIC BASE FERTILIZER FROM MUNICIPAL SEWAGE SLUDGE            ABSTRACT OF THE DISCLOSURE      A process for the production of a granular fertilizer product from biological or municipal sewage sludge is described.  This process involves (1) gently blending the biological sludge with sufficient lime-containing material (preferably lime kiln dust) to raise the pH of the blended material to at least 11 pH units, and preferably at least 12 pH units, in such a manner as to avoid or prevent the formation of a slurry; (2) then conditioning the blended materials at a temperature of 180°F and a pH of at least 11, and preferably at least 12, for a time sufficient to effectively kill or otherwise destroy a significant percentage of the pathogens present in the sludge; (3) blending the conditioned sludge with a second lime-containing material (preferably cement kiln dust or fly ash) and a binder (preferably lignosulfonate); (4) then agglomerating the blended materials to form pellets or granules; (5) drying the pellets or granules to a moisture content of less than 15 weight percent; (6) and curing the dried pellets or granules at ambient temperatures for a time sufficient for the pellets or granules to develop sufficient physical strength to be used as a fertilizer.  The product of this invention can be used directly as a low-grade fertilizer or, if desired, additional nutrients or other additives can be added to upgrade its fertilizer value.

Abstract: Reduction of laser threshold in an electrically pumped vertical cavity laser is the consequence of interpositioning of an electrode layer intermediate the active, photon producing region, and at least one of the two Distributed Bragg Reflectors defining the laser cavity. The advance is a consequence of the lowered pump circuit resistance due to elimination of one or both DBRs - in particular, to elimination of the p-doped DBR - from the pump circuit.

Abstract: A toxic waste fixant for detoxification of a contaminated material includes a mixture of ferric sulfate, manganese sulfate, organophilic clays, an oxidizer and aluminium sulfate. The respective amounts are preferably about 15-19% b.w. of ferric sulfate, about 15-19% b.w. of manganese sulfate, about 37-46% b.w. of organophilic clay, about 16-19% b.w. of an oxidizer and about 0-12,5% b.w. of alumimium sulfate.      All or part of the ingredients in said fixant may be added as a pretreatment into contaminated materials such as soils, sediments, or sludges. This pretreatment can range from 0 to 100% b.w. to said material. The fixant is blended with various amounts of Portland cement, and/or blast furnace slag, or lime, or gypsum, or coal fly ash, or cement kiln dust as a means to derive a chemical fixation treatment for contaminated soils, sediments, and sludges to prevent the leaching of organic and inorganic compounds and elements.

Abstract: ABSTRACT OF THE DISCLOSURE A multi-part mailing assembly includes a single-layer form of detachable parts related to each other. The assembly is combined with an envelope that both exposes and secures the parts and other contents for specialized mail handling. Spaced horizontal and vertical tear lines separate the form into multiple related parts. In addition, opposite marginal edges are also perforated for continuous pin or sprocket feeding of the stock through printing equipment. Additional vertical tear lines remove the margins after printing, and transverse tear lines separate the forms from each other. The envelope secures the parts after being detached from each other into position within compartments of the envelope along with other inserted materials. Open or transparent areas allow printed information on the appropriate portion of the related part to be seen from the outside of the envelope after it is sealed for mailing. One or more of the printed parts may be removed from its place inside the sealed envelope without disturbing or exposing the balance of the inserted contents.

Patent CA-2089238-A1 (CA)
Inventor: CONLEY PAUL G
IPC: A61F9/00
Filed: 1993-02-10
Abstract: An aspiration control system includes a motor (18) and vacuum pump (22) which are controlled by a system  controller  (26),  in  accordance with  input commands to provide a precise,  continuously variable vacuum or negative pressure within a vacuum chamber (38) and surgical handpiece (70).  The resulting vacuum is proportional to the control signal sent from the system controller (26) to the motor (18).  A transducer (36) samples the vacuum output and produces a signal fed to the  system controller  (26).   The  signal  is compared with a variable input signal set by a potentiometer (34)  or other signal source activated by the input commands so that the transducer signal tracks the voltage source signal.  Therefore, the vacuum output of the vacuum pump and motor relates directly and predictably to the input commands.   In one embodiment the motor is a brushless DC motor.   The system may also include a pinch valve (76) provided on a fluid aspiration conduit communicating between the surgical hand-piece (70) and vacuum chamber (38) so that the fluid aspiration at the handpiece  (70)  may be  controlled independently from the negative pressure level created in the vacuum chamber (38).

Abstract: Known systems based on layered video coding and video decoding code with inadequate efficiency because the new high-resolution picture is predicted by means of the switching means present in the system either on the basis of the preceding high-resolution picture or on the basis of the instantaneous low-resolution picture. According to the invention, designing the switching means for the adjustment of the ratio of the signal representing the preceding high-resolution picture and the signal representing the instantaneous low-resolution picture and for then adding both the adjusted signals achieves a gain of 3 dB in the prediction with the correct ratio, and this results in an improvement in the coding efficiency.

Title: Cell resequencing system for a telecommunication network
Inventor: VERHILLE HENRI A J
IPC: H04L12/56
Filed: 1993-09-17
Abstract: ABSTRACT               CELL RESEQUENCING SYSTEM FOR A TELECOMMUNICATION NETWORK A cell resequencing system for a resequencing section (RS) having two inputs (S1n) coupled to inlets (I2n) of a switching network (SN2) via transmission links (TLn) arranged in a link group (LG).  The cells transmitted from the inputs to outlets (N2m) of the switching network are subjected to a first variable time delay and are then stored in latching means (R2m) for a second variable time delay prior to be released to an output of the section.  This second delay is so chosen that for each cell the sum of the first and second delays is substantially equal to a predetermined constant time value.       The size of the latching means is determined by the difference between this predetermined constant time value and a fixed transfer delay (TD) below which no cell can be transmitted from an input to an outlet.       A method for correlating in phase two clock means (CK1/2) producing time stamp values (tA1,tA2/tB) is also claimed.  The first clock means sends a first time stamp value (tA1) to the second clock means (CK2) which then generates a second time stamp value (tB).  A time stamp compensation value (TTC) equal to the difference between the second and the first time stamp value is then determined at the location (A/B) of either the first or the second clock means.  This time stamp compensation value is function of both the phase difference between the two clock means and the fixed transfer delay (TD).

Abstract: A  breathing  device  for  use  by  persons  engaged  in activities  within  an  environment  of  sub-zero  air temperatures.  The temeprature and humidity of inhaled cold air is tempered and moderated by passing through a matrix of plates secured in an opening in the frontal area of the mask structure.  Exhaled warm air is expelled in reverse flow over the same route through the matrix of plates.  No valves or moving parts are involved in the operation of this device.   This feature is unique and original relative to prior art which is employed in the design of patented devices of this type which I have identified during my search of this classification.  All previously patented devices in this classification which I  could  discover  required  valves  and  separate  air passages in their operation.
