Abstract: OSCILLATING SOOT BLOWER MECHANISM            ABSTRACT OF THE DISCLOSURE       An accessory transmission mechanism for causing the lance of a soot blower of the well-known IK long travel type to oscillate about its longitudinal axis, rather than rotating continuously in the conventional manner during its projecting travel and during its retracting travel, and which also drives the lance longitudinally, consists of a conversion transmission assembly adapted to be installed in the carriage of the blower.  The con-version assembly includes a tubular idler shaft fitted on and rotatable independently of a solid inner shaft which is mounted in the blower carriage as a simple replacement for a correspondingly mounted shaft of the standard blower carriage.  The tubular shaft drives a Scotch yoke mechanism and also drives the walking pinions which drive the carriage along the beam to actuate the lance longitudinally.  The Scotch yoke mechanism, which is contained in an accessory housing attached to the side of the carriage, drives the solid internal shaft, which is geared to the hub of the lance to oscillate the latter.

Abstract: ABSTRACT OF THE DISCLOSURE A sonobuoy consists of a buoy which floats on the sea surface and a sensor, including a hydrophone, which is submerged at a desired sea depth.  The sensor is maintained at the desired sea depth by making it neutrally buoyant at this depth.  A signal transmission line which extends between the sensor and the buoy for transmitting signals therebetween has no tension therein, so that the sensor is not influenced by movements of the buoy and provides a high signal-to-noise ratio.  The signal transmission line can be a fine optical fiber a great length of which can be accommodated in a small volume, enabling the sensor to be used at great sea depths.

Abstract: CHARGED NON-CONDUCTIVE POLAR GAS SENSING   ELEMENT AND DETECTION SYSTEM                Abstract of the Disclosure An air pollutant and/or fire combustion sensing apparatus includes a charged insulating sensing electrode layer establishing an electric field as the result of electric dipoles and/or electric monopoles in or on the sensing layer.  The layer has a high surface and bulk resistivity.          The layer has a minimal water absorption at environmental humidities.  The electric field of the sensing layer creates electrostatic sensing reactions with the gaseous products of combustion and environmental pollution and produces an amplification of the charge detection characteristic to alter the charge of the electrode.  In a capacitive sensor, the sensing layer is mounted within and in spaced relation to a ground shield member.  The sensing layer is thereby exposed and produces a sensitive capacitive detector for sensing of a wide spectrum of combustion products and the like.  Optimum results are obtained by the charging of dielectric materials such as polytetrafluoroethylene (Teflon TFE), perfluoroalkoxy (Teflon PFA), fluorinated ethylene-propylene (Teflon FEP), polystyrene or polyethylene, which also provide detection as the result of their gaseous adsorption characteristics.  A high input impedance detecting circuit with good electrometer characteristics responds to the change in the charge, par-ticularly on the surface.

Abstract: Application of Everhard H.B. Bartelink Abstract of the Disclosure A remote supervisory system operating in conjunction with a telephone company central office to enable monitoring of telephone subscriber premises over existing telephone circuits. Auxiliary equipment is installed at the subscriber's premises and coupled to the subscriber's telephone circuit.  The equipment includes sensors which monitor the condition of the premises.  If an abnormal condition occurs at the premises, the condition is sensed by one of the sensors and the equipment, in response thereto, creates a temporary off-hook condition on the subscriber's circuit, transmits to the central office alarm report signals indicative of the abnormality, and then goes back on-hook.  The off-hook alarm report signal transmission may be effected repeatedly to assure reception at the central office. The central office identifies the subscriber as it does in the case of a normal outgoing call, senses the transmitted alarm report signals and stores the signals and subscriber's identity in its memory.  The central office then initiates a call to a predesignated action center and reports the subscriber's identity and the nature of the abnormality.  The auxiliary equipment at the premises may also be equipped to monitor the condition of the subscriber circuit by creating an off-hook condition thereon not only upon the occurrence of an abnormality, but also periodically.  If one of the scheduled periodic off-hook conditions is not sensed by the central office, that fact is treated and reported by the office as a line integrity failure alarm.  The equipment at the premises may also include command receivers which are responsive to command signals stored in the central office memory by the subscriber for initiating control functions at the premises.  The command signals may be transmitted to the central office by the subscriber from any remote telephone subset.  As a further feature, the equipment may be coupled to control a recording unit which enables the subscriber transmit and store messages of extended duration by placing an incoming telephone call to his premises.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved audio power amplifier system.  The system has an amplifier with an output signal which varies in response to an input signal.  The amplifier has two power inputs and a feedback loop around the amplifier which provides a closed-loop transfer function.          The two power inputs to the amplifier are provided by tracking switching regulators connected to the amplifier output signal.          Alternatively, a single tracking switching regulator with a dual output may be used.  This arrangement provides power supply voltages to the amplifier which vary in direct response to the amplifier output signal which reduces the power dis-sipated by the amplifier.  Thus, it is possible to provide a high-efficiency amplifier system, while retaining low distortion.

Abstract: ABSTRACT OF THE DISCLOSURE      Elemental sulfur is recovered from acid gas containing hydrogen sulfide (H2S).  Such H25 may be produced from any conventional source such as an amine desulfurization plant. The acid gas and the H2S therein is concacted with oxygen (o2) or the oxygen in air in a stoichiometric amount such that one-third, by weight, of the flowing H25 is oxidized (the H2S is measured and the o2 thereby controlled).  Oxidation takes place thus:               H25 + ? o2 +  So2 + H20 The sulfur dioxide (SO2) indicated in the equation above is then further reacted in a conventional Claus process sulfur recovery plant with the balance of ths H2S. That is, due to the fact that only the said one-third of the H2S is oxidized, there is a two-thirds remainder of the same and it is this two-thirds remainder which is referred to above as the "balance."  This balance is converted to elemental sulfur (S) in the following manner: 2H2S + So2  +  3S + 2H2o

Abstract: ABSTRACT OF THE DISCLOSURE        A method for producing decorative glass objects in which the decoration is created by blisters formed by air bubbles within solid glass and/or by a pattern on the outer sufrace of the glass.  When producing glass objects provided with air bubbles by means of known methods the bubbles remain on the surfaces of the objects which then easily break.  In addition, the bubbles are formed at random, which may make them appear as dim impurities. When, in accordance with the invention, molten glass is poured from above in the shape of a band into a hot mould, the molten glass is spread into the mould in layers between which microscopic air bubbles remain.  As the glass surface cools, the air enclosed within the bubbles expands in the molten glass which, while cooling, leaves the bubbles as clear pearls inside the glass. As the molten glass is spread in layers towards the wall of the mould, a pattern is formed as the glass surface cools.

Abstract: APPLICATION FOR PATENT                       ON               CHILD'S CONVERTIBLE DESK by D. F. Martin P. O. Box 55 Williamstown, Ontario ABSTRACT Most children's desks made and sold commercially serve mainly a single purpose, i.e. for writing or other activity that can be performed on a small horizontal surface.  Few of them have any flexibility which permits them to be used for a variety of purposes.  Some may have a tilting top that can be used either in a horizontal position for writing or at an angle for drawing.  But none provide both these features plus a facility for converting the desk into a table with adequate surface area for playing games or serving food.      In the invention described, all these features are pro-vided for by making the desk top convertible.  This is done by constructing the top of two layers equal in dimensions, the too layer consisting of a single folding leaf and the bottom layer of two leaves, one solidly attached to the desk frame and the other hinged to the frame.  The folding leaf is hinged to the fixed lower leaf so that it can either lie at rest on top of the bottom layer to form a writing surface, or fold into an easel position or through a full 180° to form one half of a table top surface, the bottom layer form-ing the other half.  The hinged leaf of the bottom layer is attached to the desk frame in such a manner that it can either lie flat in a plane with the fixed leaf or can be swivelled through 90° into a vertical position to form a support for the folding leaf when in an easel position.      The invention also contains another feature in that a seat is provided as an integral part of the desk unit.  Al-though this feature in itself is not unique, advantage is taken of it and patent rights claimed because the seat back is utilized as a fixed support for the folding leaf when in table top position.
