Abstract: PHN. 8631.            ABSTRACT:     The invention relates to an electrical heat-ing apparatus for water, comprising a heating chamber and an electric heating element, as is for example generally employed in domestic appliances such as coffee-makers.  The construction in accordance with the inven-tion serves to mitigate the problem of scale deposit on the wall of the heating chamber and for this purpose comprises an automatic device for temporarily raising the temperature of the wall to the decomposition temper-ature of scale, whilst the wall is manufactured of a material which can withstand this temperature, such as for example quartz-glass.

Abstract: WIDE ACQUISITION RANGE MSK DEMODULATOR INPUT CIRCUIT    Abstract of the Disclosure An input circuit for a wide acquisition range minimum shift keying demodulator includes a pair of phase-locked loops (PLL).  Each PLL is designed to receive from a frequency doubler a respective one of two discrete spectral lines in the frequency spectrum separated by a frequency equal to the bit rate.  Each PLL operates at one of three frequencies including its own search position frequency and the search position frequency of the other PLL plus or minus the bit rate.  A logic decision circuit responsive to the PLLs  operates with a frequency synthesizer connected to a mixer at the input of the doubler so that when one PLL locks to one spectral line, the other PLL is operated at its respective frequencies to lock to the other spectral line.

Abstract: ABSTRACT OF THE DISCLOSURE          A motorized damper for a forced air home heating system, wherein a damper plate is mounted in a housing for 360 degree continuous rotation in one direction, to successively open and close the damper.          An electric motor rotates the damper and is connected through a first two-way switch actuated by the damper plate to a wall mounted second two-way switch and thence to a power source.  When an occupier enters the room and operates the wall two-way switch, the motor rotates the damper plate from closed to open position, at which time the damper plate actuates the first two-way switch to de-energize the motor.  When the occupier leaves the room, he again operates the wall switch to turn on the motor and rotate the damper plate to its closed position, whereupon the damper plate actuates the first two-way switch again to shut off the motor.  A number of dampers can be centrally controlled by a central processor and an override switch may be used so that when an occupant enters a room, all of the home dampers except that in such room will close for a short time to direct the entire furnace output to that room to rapidly heat the room.

Abstract: Abstract of the Disclosure A method and apparatus for forming a fiber mat is disclosed.          The attenuation rate of the attenuator or strand advancing apparatus is varied as the attenuator traverses across the mat formation surface such that a constant rate of attenuation of glass filaments from a bushing is realized.  This results in more consistent diameter filaments being formed and thus results in the formation of a more uniform mat.  The attenuator may also be employed to lay down mat from previously produced forming packages of strand material from any natural or synthetic fiber.

Abstract: ABSTRACT OF THE INVENTION The invention relates to methods and apparatus for effecting deep water repair of pipelines especially during a pipelaying operation. A damaged portion of the pipeline is located and is prepared for receiving a pipeline plug member by cutting away the damaged portion leaving a prepared pipeline end section. The pipeline plug member is secured in a submersible repair frame which is lowered from a floating vessel into an operational relationship with the prepared pipeline end section. The plug member is aligned with the pipeline end section and is inserted into the end section. Thereafter, the plug member is sealingly secured in the pipeline end section and the repair frame is removed from its operational relationship with the pipeline. The pipeline is dewatered and the end section is then raised onto a floating vessel. The repair flame, in addition to including means for holding and manipulating the plug member, also has a manually operable control panel manipulating means for controlling operations of the repair frame, and a submersible vehicle docking station to position a submersible vehicle in an operative relationship to the control panel manipulating means. The repair frame is preferably lowered to the bottom of the body of water with a pick up line or a pilot line attache the plug member.

Preferably the complete closure is formed as an integral unit out of a polymer such as polypropylene in such a manner that the spring structure consists of upstanding resilient posts on the top of the closure member and so that the cam structure consists of substantially non-bending or rigid portions of the lid which are located so as to contact and deform the posts during movement of the lid.  The complete closure is considered quite desirable because of its effectiveness and because it can be manufactured at a very nominal cost using straight pull injection molding dies to form the operative parts of the lid and the closure member.
