Abstract: Abstract of the Disclosure A fluid flow level detector contacts a fluid surface in an open channel providing a fluid surface height signal re-lated to a predetermined reference height level.  The flow level detector immediately withdraws upon contacting the fluid surface and exhibits a time delay before subsequently seeking to regain surface contact.  Auxiliary signals are produced related to specific predetermined fluid surface height levels.  The fluid surface signal is directed to a computer where it is converted into a signal related to flow volume by a function read-only memory.  Totalized flow volume is provided along with an optional time display recording.

Title: Light reflecting surface
Inventor: BAGSHAW ROBERT B
IPC: E01F9/619
Filed: 1975-12-19
Granted: 1980-03-18
Abstract: The invention relates to highway safety aids for wet weather reflectivity in the form of three dimensional structures or elements that are capable of being placed on a road, such as by applying them to a road along with a paint or other carrier to secure them to a road, such that light from a headlight will be impinged thereon and returned straight back to the source of the light. The structures or elements are made retroreflective by glass beads on a foil backing, or partially silvered beads, for example. The retroreflective elements have a covering with a refractive index that is about the same as that of water. The refractive index is sufficiently high that light that is impinged thereon is still within a visible range after passing through (into and out of) the exterior covering. The elements or structures are of three dimensional discrete shapes having some surface portions that are not parallel to each other so that there are presented to a beam from a headlight many tiny surfaces for impingement of light thereon from headlights delivered at an angle of incidence greater than 45 degrees. Unlike conventional retroreflective elements, these elements do not "black out" when wet, but allow wet weather retroreflectivity, and accordingly, allow a real highway safety advantage.

Abstract: Abstract of the Disclosure A novel modulator converts a sequence of N'ary codes representative of an element P of a set (O, 1, 2, ..., N - 1) into a sequence of 2N-phase carrier pulses, where N = 2n, n being a positive integer.  A phase shift in the carrier signal between each carrier pulse and the next preceding one is selected from P.pi./N and (P + N).pi./N in compliance with a prescribed law of correlation between the N'ary codes in the sequence.  Alternatively, the Carrier signal is given in each carrier pulse a phase selected in the manner specified.  For convenience of resorting to the prescribed correlation law, th N'ary code sequence may be converted into N trains, corresponding to the respective elements P, of three-level signals, 0 and +1. In the train corresponding to a particular element, the three-level signals are successively produced with the prescribed correlation law, such as with resort to bipolar or duobinary technique.  A novel demodulator converts the 2N-phase carrier pulse sequence into the original N'ary code sequence.

Abstract: ABSTRACT OF THE DISCLOSURE          An improved system for directing a web of flexible material to a predetermined location, and more particularly, a system for directing the end or tail of a moving web into threading engagement with rolls forming a nip or the like.  In this system a gas such as air is directed through a restricted opening under pressure whereupon it attaches itself to a flow attachment surface due to the "Coanda effect", so that it entrains ambient air and the moving web tail.  In a preferred form of the system, after the web tail has been entrained and conveyed a predetermined distance, a substantial portion of the combined flow of the entraining gas and the entrained ambient air are diverted off toward a different direction.  At the location of diversion, restraining means is provided for preventing the web tail from moving with such substantial portion of combined flow.          Another aspect of the invention resides in orientation of the restricted opening and flow attachment surface so that the web entrained thereby defines a concave path.  Still another aspect resides in utilizing two Coanda nozzles in the system, the first of which is positioned to throw the web to the second across an open space of sufficient magnitude to dissipate a substantial portion of the gaseous flow from said first nozzle so that it does not interfere with operation of the second nozzle.

Abstract: POLLUTION CONTROL SYSTEM FOR COKE PRODUCING INSTALLATIONS                ABSTRACT OF THE DISCLOSURE       A pollutant collection and removal system is provided for use with a horizontally arranged battery of coke ovens.  A receptacle having a coke entry opening is positioned in front of the coke guide and receives the total coke pushed from an oven and a hood carried by the support for the coke guide substantially encloses the coke guide and overlies the coke entry opening and enshrouds the discharged coke and pollutants generated during the coke pushing operation.  The coke is distri-buted within the receptacle for quenching and, after the pushing operation, the receptacle is moved from the coke guide and transported to a quenching station.  The recep-tacle is continuously subjected to a source of suction to move atmospheric air into and from the oven being pushed and into the hood and the receptacle and to con-tinuously withdraw from the receptacle pollutants moved and discharged into the hood during the pushing operation and pollutants generated from the hot coke contained within the receptacle.  The withdrawn pollutants are removed from the carrier air which is then discharged to the atmosphere.  The system is readily adaptable for use with existing coking installations.
