Abstract: CONTINUOUS MOTION SPIRAL STACKER      ABSTRACT OF THE DISCLOSURE Apparatus and method for accumulating generally flat articles of substantially the same size and shape into stacks of specific count.  The apparatus comprises at least one vertically oriented spiral member having an exterior leading edge and an interior trailing edge.  A prime mover rotates the spiral member about its horizontal axis of rotation.  A product stack-building area is provided through which the leading and trailing edges of the spiral member passes once each revolution thereof.  An infeed device feeds products at substantially the same elevation to the top of the stack-building area and onto the outer surface of the spiral member constituting a product support surface which recedes from the article infeed elevation at a predeter-mined rate.  At least one side plate is provided to keep the products within the stack-building area.  An outfeed device to receive stacked products passes through the spiral member at an elevation just below the trailing edge thereof.  Products are fed to the top of the stack-building area.  The spiral element is rotated through the stack-building area, and as its leading edge passes there-through, a new product stack is started thereon and is segregated from the previous stack accumulated on the spiral member.  The previous accumulated stack is deposited on the outfeed device by the trailing edge of the spiral member.

Abstract: ABSTRACT      A high-speed winder for web materials such as sheets of paper includes a web separator.  The web separator comprises a pair of rotating rolls, one of which has a recess therein, and the other of which carries a rigid member to force the web into the recess and separate the paper.  A very soft compressible member lies on each side of the rigid separator, and portions thereof hold the web tightly against the first roll, on each side of the recess, to prevent the web from being drawn into the recess by the separator.  The leading one of the pair of resilient members is shorter than the trailing member of the pair, so as to pass over the web until such time as the separator is pressed against the web directly over the recess. Thereupon both of the soft compressible members are pressed against the web and hold the web against movement while the separator member pushes the web into the recess.  The web separator of the present invention permits accurate separation of lightweight paper webs at speeds in excess of 1,000 meters per minute.

Title: Removal of ammonia from wastewater

IPC: C02F1/28

Granted: 1989-08-15
Abstract: ABSTRACT OF THE DISCLOSURE A process is disclosed for the continuous removal of ammonia from wastewater which converts the otherwise undesirable ammonia to a commercially useful end product such as ammonium phosphate.  The process is carried out in an Advanced Separation Device which comprises a plurality of chambers moving about a cir-cular path in periodic fluid communication with a plurality of fixed feed and discharge ports.  The chambers are filled with a zeolite adsorbent which effectively adsorbs the ammonium ions contained in the wastewater at low pH levels but which, when contacted with an alkaline regeneration solution, releases the previously adsorbed ammonium in the form of ammonia gas, for which the zeolite has no affinity.  By virtue of the ASD design, it is possible to add acidic materials to the wastewater in an intra-stage fashion i.e. during the adsorption step so as to optimize process efficiency.  Similarly, intra-stage addition of alkaline materials during the regeneration step results in increased process efficiency.  The process may be practiced with both industrial and municipal waste-waters.

Abstract: ABSTRACT OF THE DISCLOSURE                A method and apparatus for transmitting data signals between two control devices connected to a loop transmission system are disclosed wherein data signals are transmitted in the form of signal blocks.  In addition to the data signal, each signal block includes a receiver address having a block start identifier which precedes the data signals, and a sender address with a block end identifier following the data signals. In response to the appearance of the block start identifier and the receiver address, the signal block received by a control device is copied in the control device identified by the receiver address.  The copying is undertaken for possible further processing.  The signal block is then forwarded to the next control device via the loop, with the block start identifier cancelled.  Before forward-ing, an acknowledgement signal is attached to the sender address.      The acknowledgement signal is recognized by the control device which sent the data signals.  Such recognition occurs in response to the appearance of both a block end identifier and the sender address.  The sending control device then accepts the returned acknowledgement signal for evaluation thereof.     .. . .

Abstract: ABSTRACT:          Method and arrangement for suppressing coherent inter-ference effects in magnetic resonance signals.     IN NMR images, which are constructed from resonance signals, for example using Fourier zeugmato-graphy, coherent interference effects resulting, for example, from "Leak-through" of NMR signals from one sequence to a next sequence of resonance signals, can cause artefacts to occur in the images, which, depending upon the kind of interference, become manifest in the image as interference lines, ghost images or conspicuouc dots. A method is proposed for reducing the effect of this interference by smearing the artefacts out over the image as noise.          For this purpose, the phase of the reference signals is randomly modulated between successive measure-ment cycles of the resonance signals. The reference signal is used to form excitation pulses for producing resonance signals in a body and further for the synchronous detection of the resonance signals.           Fig. 2.
