Title: Solubilizing and oxidizing of peat

Abstract: SOLUBILIZING AND OXIDIZING OF PEAT               ABSTRACT OF THE DISCLOSURE          Methane is produced from peat by solubilizing the phenolic polymers therein, and oxidizing the solute to produce short chain molecules.  The short chain molecules are fermented to produce a gas that this scrubbed to remove CO2 to produce methane.  Solubilizing takes place in a vertically oriented pressurized vessel that is circular in cross-section and divided into a number of regular vertically elongated compartments, each comprising a circular sector in cross-section, and extending the majority the height of the vessel. Slurried peat is fed into the top of one compartment while another compartment is being emptied from the bottom, the compartment being filled or emptied being progressively changed in response to rotation of a central shaft in the vessel.  Oxidation of solubilized peat takes place in a structure that transports the solubilized peat in a substantially vertical wave path from an inlet to an outlet with oxygen being introduced at the bottoms of segments of the wave path, and CO2 being withdrawn from the tops of segments of the wave path while the solubilized peat is maintained at a pressure above atmospheric.  Coolant is circulated around the wave path to remove the exothermic heat of reaction, and the coolant is flashed into steam used elsewhere in the process.

Abstract: INSIDE POWDER STRIPING APPARATUS               ABSTRACT OF THE DISCLOSURE         This relates to a powder applicator for applying a coating stripe in powder form to inside seams of can bodies.  The powder applicator is particularly adapted to be utilized in conjunction with welding apparatus for weld-ing the side seams of can bodies and wherein the diameters of the can bodies are too small to permit the provision of the customary excess powder return duct.  The powder appli-cator is located at the 12:00 o'clock position and thus the excess powder will not merely fall out of the applicator. Accordingly, there is provided a channel defined by a porous block having air or gas circulated therethrough and wherein the terminal end of the channel is closed by a deflector block which will deflect any excess powder out of the appli-cator into an overlying hood which is primarily intended to take away powder overspray which normally occurs between adjacent, but spaced, can bodies.

Abstract: IMPROVED LIFTING APPARATUS FOR HANDLING DOWN-HOLE TUBULARS                         ABSTRACT         An improved boom for a drill rig is described which includes two rotatably mounted clamps which are rotatable between a side loading position, to facilitate loading and unloading in the horizontal position, and a central position, in which a clamped tubular is aligned with the drilling axis when the boom is in the vertical position. An automatic hydraulic sequencing circuit is provided to automatically rotate the clamps into the side loading position whenever the boom is pivoted with a down-hole tubular positioned in the clamp.  In this position, the clamped tubular is aligned with a safety plate mounted on the boom to prevent a clamped tubular from slipping from the clamps.  A safety frame is formed between the tower of the drill rig and the vertical boom by a slidable bolt mounted on the tower and an annular receiving member mounted on the boom to receive the end of the bolt.  This boom also includes an improved pivoting linkage which facilitates the transport of the rig.

Abstract: TIME DIVISION SWITCHING SYSTEM            Abstract of the Disclosure A multimode time division switching system is disclosed having facilities for the serving of conference calls between port circuits in at least three different modules.  Each module serving a conference call transmits a series of call data words to the other modules serving the same call over a special bus system interconnecting all modules.  Each word contains information including a module ID number and a time slot number as well as the message or intelligence representing the subject matter of the call. The transmitted ID number specifies the identify of the other modules serving the same call and to which the word is directed.  The transmitted time slot number specifies the time slot in which the call is to be served by only a first one of the specified receiving modules.  This first module responds to the reception of the word and serves the call in the specified time slot.  The other specified module responds to the reception of the word, derives a new time slot number and serves the call in this derived time slot.

Abstract: ABSTRACT OF THE DISCLOSURE           A vehicle emissions control system includes an air pump (12), a catalytic converter (22) communicated to the air pump, and a bleed control valve (28) which controls the quantity of air communicated from the air pump to the catalytic converter.  The bleed valve includes a support arm (50) which suspends a valve element (40) adjacent a tapered valve surface (36).  The support arm relaxes in response to repeated flexing due to the pulsating output of the air pump. Ac-cordingly, when the vehicle is new, the valve element is held away from the valve seat to permit substantially uninhibited communication through the bleed valve so that almost all of the air which would other-wise be communicated to the catalytic converter is bled off.  As the vehicle is used, the support arm relaxes, which permits the valve element to move progressively closer to the valve surface, thereby decreasing the quantity of air bled off through the bleed valve to thereby progressively increase the quantity of air communicated to the catalytic converter.

Abstract: ABSTRACT               A DIGITAL TIME-DELAY BEAMFORMER                   FOR SONAR SYSTEMS            There is described a digital sonar receiver having a novel beamformer, own doppler nullifier (O.D.N.), and adaptive time varied gain controller. The beamformer interrogates a multi-element transducer by utilizing an interleaved sampling scheme which samples the elements in the transducer array sequentially, in such a fashion that continuous, uniformly spaced samples are obtained.  The samples are subsequently converted into digital format, weighed and summed. The O.D.N. eliminates the own ship's doppler effect on the beam output signal resulting in a half beam output signal representative of the target doppler, The O.D.N. offsets the frequency of the beam output signal and a digital generated signal representative of the own ship's doppler.  The O.D.N. multiplies these two offsetted signals resulting in a signal lying in each of the sum and difference frequency bands for which the signal lying in the difference frequency band corresponds to the target doppler.  The adaptive time varied gain controller varies the gain of preamplifiers at the input of the sonar receiver to be inversely proportional to the momentary average reverberation level of the medium in which the receiver operates.  The adaptive time varied gain control apparatus initially sets the gain of the preamplifiers to be inversely proportional to a standard reverberation curve during the first ping-cycle and subsequently updates the gain of the preamplifiers during each successive ping-cycle by computing a gain correction from the average value of a pre-determined number of beam output signals.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a method for synchronizing a current-rectifying synchronous motor, with a mains-supply, through a frequency-converter, the mains and motor being at approximately the same frequency.          Pulses are taken from the mains-voltage through a trigger-stage and are compared with corresponding pulses from a rotating-field recognition-system of the motor in a logic circuit.  In the in-phase condition, the pulses taken from the mains-voltage are connected in order to control the valves on the motor-current rectifier, and the pulses taken from the recognition-system are suppressed.  At the same time the voltage in the direct-current intermediate circuit is adjusted, through the mains current-rectifier, to a fixed value, after which a synchronizing switch is closed.
