Abstract: MULTI-TIME DELAY POWER CONTROLLER APPARATUS    ABSTRACT    Multi-time delay power controller apparatus for providing time-delayed power or control signals to associated electrical equipment, such as computers and disc drives, comprises a power stage configured for connecting to a conventional power outlet, a D.C. power supply connected to an interval D.C. voltage bus, an out-put stage having a plurality of time delayed outputs and a plurality of time delay timing stages connected in electrical series to one another between the D.C. voltage bus and ground.  Each such timing stage includes a timing circuit, a comparator circuit and a normally open control relay.  Coils of odd numbered timing stages are connected to ground and of even numbered stages to the D.C. voltage bus.  The timing stages are connected so that the timing out of one stage starts the timing of the next-in-sequence stage, timing of the first-in-sequence timing stage being started when the apparatus is turned on. The control relays are actuated when a stage times out, thereby causing a time delayed control signal to be provided to the output stages.  When time delayed power outputs are provided, the time delayed control signal energizes a normally open power relay which connects the associated power output to the power stage.

Abstract: (57) ABSTRACT OF THE DISCLOSURE            This publication describes a method and an apparatus for the utilization of the heat of melting of water.  In accordance with the method, the gaseous heat transfer medium is led into a turbine (2) where the medium is expanded to a lower pres-sure.  The heat medium is led to a container (5) where water is conveyed via a pipe (6), the heat medium with heat energy stored into it from the water is led from an upper part (14 of the container (5) to a compressor (16) where the medium is compressed to a higher pressure by means of energy obtained from the turbine (2) via a turbine shaft (3) and from a motor (18) via a shaft (17), and the heated medium is led out from the system.  In accordance with the invention, the heat trans-fer medium is expanded in the turbine (2) to such a low pres-sure that its temperature falls below the freezing point of water, a major part of the water conveyed to the container (5) is sprayed in small droplets into a spray chamber (8) where the heat of melting of water is transferred into the medium, part of the water is sprayed directly on the walls of the container (5) in order to prevent their freezing, and water with icelets falling to a bottom space (9) of the container is forced into a rotating movement in order to prevent clog-ging.  Water with icelets forced into movement is sucked out with a pump (10) from the container bottom space (9).  Accord-ing to the method, heat energy can be extracted from freezing water by means of a continuous process.

Title: Glass body formed from a vapor-derived gel and process for producing same
Inventor: FLEMING JAMES W
IPC: G02B6/00
Filed: 1987-12-10
Granted: 1992-12-08
Abstract: GLASS BODY FORMED FROM A VAPOR-DERIVED GEL      AND PROCESS FOR PRODUCING SAME            Abstract The disclosed simple, economical and rapid sol-gel process for forming a silica-based glass body, termed the "vapogel" process, comprises introduction of a silicon halide-containing gas (e.g.,SiCl4 + O2) into an aqueous medium. The thus formed sol can gel within minutes, resulting in a monolithic gel body. This gel body can be dried and consolidated into a glass body or, preferably, be partitioned into particles having a relatively narrow size distribution. The thus formed particles can be used to produce a glass body such as an opticalfiber preform, from which fiber can be drawn. Various techniques for forming theglass body from the gel are disclosed. Among the many advantages of the vapogel method are its ability to produce very homogeneous mixed oxide glasses of composition not obtainable by prior art sol-gel processes, and the advantageous mechanical properties of the gel produced by the method. The latter makes possible, inter alia, formation of particles having a relatively narrow size distribution.

Abstract: Absorption of carbon dioxide from gas mixtures with aqueous absorbent solutions of tertiary alkanolamines is improved by incorporating at least one alkyleneamine in the solution. The presence of the alkyleneamine promotes the rate of carbon dioxide absorption and the carbon dioxide capacity of the aqueous tertiary alkanolamine solution. As a result, absorption can be carried out in shorter absorber columns, and process energy requirements can be lowered by reducing the rate at which the absorbent solution is circulated.

Title: Oil shale processing apparatus and method
Inventor: RENDALL JOHN S
IPC: C10G1/04
Filed: 1988-03-02
Granted: 1992-02-04
Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for the recovery of bitumen oils from oil shale.  The method comprises crushing the oil shale to a predetermined particle size and mixing with an organic solvent to form a slurry.  The slurry is then subjected to super-critical temperatures and pressures whereby the kerogen materials break down into bitumen oils which solubilize in the solvent.  The liquid and solids are separated and the solid components are further treated under supercritical temperatures and pressures to yield further bitumen oils.  The extracted bitumen oils are separated from solvent by fractionation, and upgraded by removing an asphaltenes residue. Off-gases and asphaltenes residue from the system are burned in a limestone fluidized bed combustor, which results in environmentally acceptable emissions and supplies process heat and power.  The apparatus includes a high pressure autoclave-type vessel with an internal venturi draft tube, and a plurality of high pressure decantation vessels with internal lamellae thickeners.

Title: Propagation time detecting system with use of detected phase difference of transmitted and received subcarrier
Inventor: ICHIYOSHI OSAMU
IPC: H04B7/15
Filed: 1988-09-07
Granted: 1992-11-24
Abstract: Abstract of the Disclosure In a propagation time detecting system wherein a transmitting station transmits to a receiving station through a plurality of transmitting lines of different propagation times a transmission signal comprising a sequence of transmission data digitized by a clock signal of a clock frequency.  The receiving station receives the transmission signal through the transmitting lines as different received signals and reproduces the sequence of transmission data and the clock signal as different reproduced sequence of transmission data and different reproduced clock signals from which differences are detected among the different propagation times.  In order to improve accuracy of the detected differences, at least one subcarrier signal of a frequency higher than the clock frequency is also transmitted together with the transmission signal.  The receiving station also reproduces the subcarrier signal as different reproduced subcarrier signals which are compared with each other to produce time differences therebetween with a reduced time order.  In an application to a radar system, the transmission signal including the subcarrier signal is compared with an echo of the transmission signal from an target to produce a propagation time between the radar and the target.

Title: Laser driver circuit with dynamic bias
Inventor: BANWELL THOMAS C
IPC: H01S5/0683
Filed: 1988-11-17
Granted: 1991-03-12
Abstract: Abstract of the Disclosure The laser driver circuit of the invention stabilizes the low operating output power level of a laser (301) modulated by a digital input signal, at a fixed preset value Lo, by automatically adjusting the bias current, Ib, supplied to the laser to compensate for variations in the laser threshold due to temperature changes and aging. The circuit includes a fast photodetector (401) which is responsive to the modulated light output of the laser. The photodetector output is combined (306, 308) with a data sensitive reference signal (ir) and a preset level setting input signal (io) which is equal to ? times the desired low operating output power level, Lo, where ? is the coupling coefficient of the the photodetector. Reference signal ir varies in accordance with the input data between a zero value when the input is ZERO and a value equal to what is estimated to be the photodetector output due to the data modulation when the input is ONE. The combination of the photodetector output, the data sensitive reference signal, ir, and the level setting input signal, to, is a difference signal proportional by a factor of ? to the difference between the desired low operating output level and the estimated operating output level. This difference signal is amplified by an operational transconductance amplifier (402) having a large multiplicand, A0, when the input data is ZERO and a subtantially smaller multiplicand, A1, when the input data is ONE. The output of the amplifier drives an integrating low frequency error amplifier 309 which generates at its output the laser bias current, Ib, which is driven to a value such that the low operating power level of the laser is equal to Lo as determined by the level setting input signal, io.
