Abstract: In order to work up pyrotechnical material, I. the pyrotechnical material  is burned in a controlled manner,  the  slag  is  optionally  allowed  to  continue reacting and the crude gas formed is passed through a high-temperature region in which the gas is exposed to a temperature of  at  least  1200°C over a predetermined period in order to decompose organic substances still present; II. the crude gas formed during the combustion is cooled to a temperature below 400 C; III. the crude gas is purified under dry conditions by first feeding it into a preliminary separator,  coarse particles being separated off, and then feeding the crude gas via fine dust filters in order to separate off finely divided solids and/or IV. the crude gas is optionally purified under wet conditions by first passing it through a rotary scrubber and then passing it via one or more absorption units and V. the purified gas is released as waste air. In a variant of this process, pyrotechnical material A, where  predominantly  alkaline  reaction  products  are formed, and pyrotechnical material B, where predominantly acidic reaction products are formed, are subjected to controlled combustion in the first stage.

Abstract: A method for improved slurry-phase bioremediatian treat-ment of organic sludge and mix-tures of organic sludge and organ-ics-contaminated soils by dissolv-ing the contaminants into an aque-ous phase and microbially degrad-ing same. A high solids slurry of the sludge and soils is formed with water and an active bio-slurry con-sisting of large populations of ac-climated hydrocarbon-utilizing bacteria and small amounts of bi-odegradation residue. The slurry is passed through a plurality of in-series bioreactors (2-6) in each of which a low hydraulic shear is maintained to promote the devel-opment of a large population of microorganisms that will form flocculent suspensions. The output from the series of bioreactors is flowed continuously or semicontinuously to a liquid-solids separator (7) to partition the mixed liquor bio-slurry from the biode-graded waste residue. The mixed liquor bio-slurry containing small amounts of biodegradation residue is returned to the slurry being processed for recycling. Off-gas components from the system are recirculated back to one or more of the bioreactors, to re-turn high volatility toxic constituents for increased microbial degradation and control of volatile toxic constituent emissions from the process. The related system is also disclosed and claimed.

Title: Maintaining precise electrostatic control using two esvs
Inventor: SCHEUER MARK A
IPC: G03G15/06
Filed: 1993-09-28
Granted: 1996-10-01
Abstract: Erroneous voltage readings of Electrostatic Voltmeters (ESVs), which have become contaminated by charged particles (i.e. toner) from developer housings used for developing latent images on a photoreceptor surface, are negated by adjusting the readings of the ESVs to compensate for the contamination of the ESVs. Additionally, The developer housing biases are adjusted by an amount equal to the difference between the voltages measured by the ESVs thereby insuring proper development and cleaning fields during development.

Title: Air conditioning and refrigeration systems utilizing a cryogen and heat pipes
Inventor: JOHNSON DALE THOMAS
IPC: F25B29/00
Filed: 1993-11-26
Granted: 2002-08-27
Abstract: A refrigeration system, which conditions the air of a conditioned space via heating and cooling cycles, includes a heat exchanger and, in a first embodiment, heat pipes. A cryogen is circulated through the heat exchanger during a cooling cycle. During a heating cycle the flow of cryogen is terminated and heat is transferred into the heat exchanger via the heat pipes. In another embodiment, the temperature of evaporation of a liquid cryogen in the heat exchanger is selected according to the desired temperature of the conditioned space, via selectable cryogen flow paths which provide different pressures and thus different evaporation temperatures. Vaporized cryogen drives a motor connected to a fan which circulates air between the condi-tioned space and heat exchanger. In still another embodi-ment, the mass flow rate of liquid cryogen is controlled as a function of the degree of superheat in evaporated cryogen exiting the heat exchanger, and as a function of a prede-termined floor temperature of conditioned air discharged into the conditioned space.

Abstract: The hockey puck has a main body portion with opposite parallel surfaces.  Ground engaging runners project from each of the opposite base portions of the puck and thus elevate the base surfaces of the puck from the ground to minimize surface contact between the puck and the ground.          The ground engaging projections are equally spaced in a circular array at a rim portion of the puck.  Openings in the puck concentrate weight at the center and periphery of the puck.  The ground engaging projections and the main body portion are formed of different plastic materials, with each plastic selected for the most desirable physical properties and performance characteristics.  Thus the ground engaging runners are relatively wear resistant with low ground friction whereas the main body portion is of relatively low hardness and provides the requisite stability and weight to the puck.  The puck is formed as a composite of an inner spider mold that forms the ground engaging projections and an overmolded portion that constitutes the main body.

Abstract: This equipment serves for the production of a shaft information for a lift plant. A cage (2) guided in a lift shaft (1) is driven by way of cables (5) from a drive motor (3) with a drive pulley (4). A redundant measuring strip (6) is mounted at one side of the lift shaft (1). A multichannel forked light barrier (7) is arranged at the cage (2). The measuring strip (6) consists of a markings track in the shape of a flag track (8) and a check track (9), which are each scanned by a light barrier. At those places, where a flag (10) stands at the flag track (8), a window (13) is arranged at the check track (9). The speed of the lift is measured by means of the flags (10) and the lift is stopped in the case of possible excess speed.      By reason of the arrangement of the flag track (8) and the check track (9), possible faults can be detected at the measuring strip (6), since one light barrier must always be interrupted by reason of the flags (10) and windows (13).
