Granted: 1992-07-14
Abstract: CONTROL SYSTEM FOR A FURNACE OPERATING IN THE CONTINUOUS BLOWER MODE                     ABSTRACT OF THE DISCLOSURE            A furnace having the capability of operating its blower continuously is provided for means for automatically shutting off the blower at the beginning of a heating cycle and resuming the operation thereof only after a predetermined time to allow the heat exchanger to heat up to a temperature that exceeds the dew point of the flue gas, to thereby reduce the occurrence of cold spot corrosion in the heat exchanger. Provision is also made, in a two speed blower system, for operating at a lower speed during continuous mode and heating cycle operation, and for operating at the higher speed during the heating cycles.

Granted: 1992-03-17
Abstract: PROCESS CONTROL SYSTEM WITH ACTION LOGGING    ABSTRACT    An integrated system for process control in which a process supervisor procedure defines parameters for one or more controller systems (or control procedures). The supervisor procedure changes control parameters only in discrete changes, and the decision to act is sufficient-ly constrained that every change must be a significant change.  Every change is logged (or otherwise reported out  to  human  experts).  Since  every  change  is  sig-nificant, the history of changes will provide a meaning-ful record which can be reviewed by human experts.

Title: High side scotch yoke compressor with motor cooled by discharge gas
Inventor: GANNAWAY EDWIN L
IPC: F04B39/00
Filed: 1988-10-12
Granted: 1994-07-26
Abstract: ABSTRACT    A compressor assembly is disclosed including a compressor mechanism mounted within a hermetically sealed housing.  The compressor mechanism includes a crankcase having a suction inlet opening providing direct communication into a suction cavity within the crankcase.          The compressor mechanism is located in an upper chamber of the housing and a motor is located in a lower chamber, the entire interior of the housing being at discharge pressure.          Suction gas is isolated from the motor so that heat from the motor does not increase the temperature of the suction gas.          The discharge tube is positioned in the lower chamber so that discharge gas flows over the motor to cool it, thereby improving efficiency.

Title: Package for recording media
Inventor: WOLF HANS-JOACHIM
IPC: G11B23/023
Filed: 1988-10-26
Granted: 1993-02-09
Abstract: PATENT     ABSTRACT OF THE DISCLOSURE           A case for video or audio cassettes composed of an upper housing part and a lower housing part that are foldably joined together by means of a hinge to completely enclose the cassette.  At least one elastic element is installed between the upper part and the lower part in such a way that when a closure is disengaged the upper and lower parts are forced apart and the package swings open automatically.  In particular, the cassette itself is located in a separate holder that is held between the upper part and the lower part in their common pivot axis, with the elastic elements then operating between this holder and the upper and lower parts.  The effect of this is that when the closure, particularly a snap closure, is disengaged, not only do the upper and lower parts swing open automatically, but the holder with the cassette is brought into an angular position that roughly bisects the angle between the upper and lower parts when open. The cassette is thus easy to remove and to replace in the holder.

Title: Synchronization of asynchronous data signals
Inventor: MOORE THOMAS E
IPC: H04J3/07
Filed: 1989-05-26
Granted: 1992-02-25
Abstract: SYNCHRONIZATION OF ASYNCHRONOUS DATA SIGNALS     Abstract of the Disclosure A method of and apparatus for synchronizing an asynchronous DS1 signal to produce a synchronized signal in the SONET format is described. The asynchronoussignal is stuffed in dependence upon a stuff request signal which is produced from a comparison with a threshold level of a phase difference between read and write phases with which the synchronized and asynchronous signals are respectively read from and written into an elastic store. The phase detection and threshold comparison are effectedsynchronously with the respective signals. To this end, the read address for the store is latched in synchronism with the synchronized frames, and its difference from the write address and the resulting threshold level comparison is effected in synchronism with the write clock for the store and hence with the asynchronous signal. The synchronizer provides a reduced waiting time jitter in the synchronized signal.

Granted: 1992-10-06
Abstract: ABSTRACT      A non-woven matrix of glass and synthetic fibers provides a rigid but resilient product having good strength and insulating characteristics.  The matrix consists of glass fibers, first, solid or hollow homogeneous synthetic fibers such as polyester, nylon or Kevlar and second, bi-component synthetic fibers which have been intimately combined with a thermosetting resin into a homogeneous mixture.  This mixture is dispersed to form a blanket.  The bi-component synthetic fibers include an outer low melting temperature sheath and a higher melting temperature core. Initial curing of the fiber matrix entails melting and subsequent fiber bonding by the material of the sheath. Final curing entails activation of the thermosetting resin. The product may be utilized in a planar configuration or be further formed into complexly curved and shaped configurations.  The product may also include a skin or film on one or both faces thereof.  A conductive material in either particulate or fibrous form may be added to improve surface finish and, if desired and depending upon the choice of conductive material, darken the appearance of the product.

Abstract: A method and apparatus are disclosed for influencing the fibers in the uppermost layer of a fibrous web lying on a screen, for example, in applying a watermark or evening the surface of the web, wherein a surface compression is exerted on the web by a screen roller and a second screen guided around the screen roller. The surface compression is maintained over a variable time period and causes a water film to appear on the upper surface of the web, in which the fiber density is much less than in the web prior to the surface compression. This water layer is forcibly aspirated from the web and the fibers therein thus experience a reorientation and become set in desired positions.
