Abstract: OPEN DRAFT HOOD FURNACE CONTROL USING               INDUCED DRAFT BLOWER AND EXHAUST                    STACK FLOW RATE SENSING             Abstract Apparatus is provided for modifying an open draft hood furnace and its control system, to produce an induced draft furnace having increased efficiency.  A blower located in the furnace exhaust stack is used to induce movement of air and combustion products into and through the draft hood .  A flow-limiting orifice located in the exhaust stack upstream from the blower causes a region of reduced pressure to exist downstream from the orifice.  A pressure signal representative of the flow rate of exhaust stack gases is sensed on the downstream side of the orifice and is communicated by a conduit to a pressure switch connected to a gas valve, which together control gas to the burner.  No gas is permitted to flow to the burner unless a predetermined reduced pressure level is achieved at the downstream side of the oxifice.  A small opening in the conduit permits a small flow of flushing air to enter the conduit.

Abstract: Abstract of the Disclosure An apparatus and method for making paper clips which includes cutting predetermined lengths of wire by advancing a continuous wire at a predetermined speed to a cutting station.  The cutting station includes knife means with the knife having a cutting blade edge for penetrating the wire and a pair of shoulders spaced from the blade edge a distance less than the thickness of the wire so that the shoulders engage and press the cut edges of the wire.          Delivery means to engage the wire are provided along the path downstream of the cutting station for advancing the wire at a speed greater than the feeding of the wire to the cutting means whereby the wire is pulled and separated as it is being severed by the knife.  The cut wire is then fed into a receiving slot.  The receiving slot is provided with a deflecting member at an acute angle to the path of the wire, and the opposite end of the slot is provided with a magnet such that as the cut wire enters the receiving slot at high speed, its inertia is reduced by means of the deflecting member, and it is properly aligned and retained against the end of the slot by the magnet means.  The cut wire is then lifted out of the slot by an elevator platform means, and the wire is engaged by a ramming plate associated with three spindles, each spindle adapted to pass through a respective die member and the die member having spiral bending edges for bending the cut wire about the respective spindles for forming the paper clip.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention concerns a process as well as an apparatus, such as a press, for the mechanical dewatering of peat to a predetermined degree of humidity, for example about 70%.  For this purpose, there is carried out a progressive compression of peat on a certain distance by continuously bringing closer pressure elements and elements loaded with humid peat.  A series of pressure blocks whose forward movement is dependent on the forward movement of a series of molds is adapted to increasingly penetrate in the molds, thereby increasing gradually the pressure within the peat.  In a second step, the penetration of the pressure blocks in the molds is maintained substantially constant for a certain distance, after which the pressure is released as a result of a progressive decrease of the penetration of the pressure blocks in the molds until contact between the latter ceases, which provides for a decompression of the peat.  In this manner, it is possible to obtain a partially dewatered peat in which the degree of humidity is homogeneous and substantially constant, such as about 70%.

Abstract: V. N. Lawford - R. Austin 15-8 LIQUID LEVEL SYSTEM                 ABSTRACT OF THE DISCLOSURE A liquid level system employs a pair of vertically spaced sensors in a tank such as a boiler.  Each sensor includes a pair of bellows.  The first bellows is enclosed by a protective enclosure while the second bellows is exposed to the interior of the tank.  The first bellows of the two sensors are interconnected and filled with a liquid forming substance, such as an alkali metal, which is in liquid phase at high temperatures, while the second bellows of each sensor and the enclosure for the first bellows are interconnected and filled with a second liquid-forming substance, such as a metal alloy, which is essentially inert.  A transducer is connected to one of the second bellows which produces an electrical output signal proportional to the difference between the pressures at the locations of the second bellows and, thus, the level of liquid in the tank.

Abstract: EXTRUDED PLASTIC WINDOW FRAMING            ABSTRACT OF THE INVENTION         The invention comprises plastic window framing for sin-gle or double glazing and single or multiple panes.  The frames comprise mullions, glass stops, nailing fins and expansion strips extruded from modified polyolefins that are weather and ultraviolet degradation resistant.  The glass stops and expansion strips are co-extruded integral combinations of a hard rigid plastic support and a very flexible sealing portion.  Since both the hard rigid portion and the flexible sealing portion of the extrusions are of the same weather and ultraviolet resistant plastic, the plasticizer being the addition for flexibility, the entire framing including the seals can be exposed to the external environment and the mullions can be of relatively simple confi-guration. The mullions are symmetrical about perpendicular planes longitudinal with the extrusion.  The mullions of identical cross-section can be used for vertical and horizontal members of the frame including intermediate mullions between panes.  Interior and exterior glass stops are identical in cross-section and can be interchanged and used for both single and double glazing with-out alteration of the glass stops or mullions.  The glass stops engage the mullions along parallel longitudinal engagements.          The engagement nearest the glazing features means to snap the glass stop into a slot which may be selected from one of several longitudinal parallel slots in the mullion.  A second longitud-inal surface on the glass stop, spaced from the slot engage-ment and opposite from the glazing, rests tightly against the mullion surface and acts as a fulcrum.  The glass stop as it is snapped into the first longitudinal slot rotates slightly about the fulcrum and thereby tightly engages the flexible sealing portion of the glass stop against the glazing.
