Abstract: A gas meter has measuring chambers each having a flexible diaphragm free to reciprocate and in so doing to operate valves admitting gas to the chambers. The drive from the diaphragms to the valves includes an adjustable crank assembly. Crank arms (25, 26) are secured by a resilient pin (27) spring fitted to one of a number of bores (30) in a tangent member (28), rotatable on a spindle (31). A worm wheel (33) mounted on tangent member (28) drives a rack member (23) secured to the spindle. Rotation of the worm wheel rotates the tangent member with respect to the spindle and so adjusts the phase relationship between the diaphragm and the valves. The bores (30) are at different radii allowing the throw of the crank arms to be varied.

Abstract: The process for operating a calender machine, having a bending- compensating roll, fixes an operating pressure for each effective point to which pressure can be applied, so that a load parameter in the pressing nip has a predetermined set value. First of all, a pressure reaction matrix is formed, the elements of which indicate the change in the load parameter in all the zones in the case of a change in pressure at only one effective point in each case. Then, in the case of a change in set value, a change in pressure compensating fully or partially for the difference between actual value and set value of the load parameter is calculated using the pressure reaction matrix successively step by step in each case for the effective point of a zone. For all the other zones, the changed actual value of the load parameter resulting from this change in pressure is calculated. If the value drops below a tolerance value, the operating pressure for each zone can be corrected by the sum of all pressure changes. These iteration calculations are carried out in a control device by a programmed arithmetic device (16).

Abstract: "MIXER CIRCUIT FOR OIL SAND"                  ABSTRACT OF THE DISCLOSURE         The mixer circuit comprises a vertically oriented, open-topped  mixer  vessel  having  a  cylindrical  side  wall terminating with a shallow conical bottom.  The bottom wall forms a central bottom outlet.  Recycled slurry and fresh water streams are fed tangentially to the inner surface of the vessel, thereby forming a vortex.  The oil sand enters as a continuous, free-flowing stream moving along a downward trajectory; the stream impinges the vortex, wherein it is dispersed and mixed to create slurry.  The slurry exits through the bottom outlet, is screened to remove oversize material, and enters a holding vessel.  Part of the slurry in the holding vessel is recycled to the mixer vessel through a pipe loop incorporating a pump.  The slurry is energized by the pump and functions to maintain and partly create the rapidly moving vortex that carries out the mixing and lump-disintegration actions.  The balance of the slurry in the holding vessel is pumped out as product.   The circuit is adapted to consistently produce a dense slurry.

Abstract: The present invention relates to a process and a device for uniform distribution of a free-flowing reaction mixture onto a continuously transported substrate over the desired width during production of foam webs.  The distribution takes place towards the sides from a feed point by means of air.     The simplest method of applying a foamable reaction mixture to a moving substrate is to centrally feed the mixture onto the substrate, which is generally a paper web carried on the conveyor belt, and to allow the reaction mixture simply to run outwards.  The paper web prevents the reaction mixture from adhering to the conveyor belt.  Generally, the film of reaction mixture which forms is of uneven thickness.  The differences in thickness are  compensated somewhat during foaming; however, the cell structure of the resultant foam is generally not uniform.     Distribution rollers have therefore already been used. However, these can be employed economically only for the production of foam webs which have covering sheets on both sides to prevent the distribution rollers from contacting the reaction mixture.  Since a bulge of reaction mixture must form in front of the distribution rollers, the residence times are relatively high.  Attempts have been made (German Offenlegungschrift 1,778,951) to distribute the bulge more quickly towards the sides using air jets, in order to shorten the residence time.  However, this measure is also unsatisfactory.     The object of the present invention was to improve the distribution of the reaction mixture to thereby achieve a film of uniform thickness with a having a relatively short residence time.

Title: Anti-icing and de-icing system for reflector-type microwave antennas
Inventor: LIPKIN CHARLES L

Granted: 1994-08-23
Abstract: ABSTRACT OF THE DISCLOSURE    An improved anti-icing and de-icing system is provided for reflector-type microwave antennas having a paraboloidal reflector and an associated feed horn for launching microwave signals onto the reflector and receiving microwave signals from the reflector. The improved system comprises a non-conductive, insulated enclosure forming an enclosed cavity adjacent the rear side of the reflector, and radiant heating means within the enclosure for heating the rear side of the reflector with radiant energy, whereby the air in said cavity is in turn heated by heat transferred to said air from the rear side of the reflector.    The radiant heating means comprises at least one infra-red heating source, and is supplemented by a highly reflective mirror coating disposed on the inside surface of the insulated enclosure behind the heating source to direct the radiant energy emanating from the back of the heating source to all regions of the paraboloidal reflector.  Sections of highly reflective mirror coating are also provided on the rear surface of the paraboloidal reflector itself immediately in front of the heating source to divert excess radiant energy emanating from the front of the heating source and to disperse it to all regions of the paraboloidal reflector.

Title: Range limiting system for differentiating received signals
Inventor: LANDT JEREMY A
IPC: G01S13/82
Filed: 1989-12-28
Granted: 1999-01-19
Abstract: Briefly, the range limiting system of the invention is capable of differentiating desired received signals having an amplitude above a predetermined threshold level and at least one other recognizable predetermined characteristic, from other received signals below that predetermined threshold amplitude.          The system has a means for combining the received signal, which is of unknown amplitude which may be above or below the predetermined threshold amplitude, with a known signal of the predetermined threshold amplitude having at least one other predetermined characteristic which is distinguishable from the other recognizable characteristic of the received signal.  The output of the combining means passes to a signal processing means which produces an output signal whose other recognizable characteristic is determined by the received signal only when the received signal is above the predetermined threshold amplitude, and by the known signal when the received signal is below the predetermined threshold amplitude.  The presence or absence of the desired signal is determined on the basis of analysis of the other predetermined characteristic of the output signal of the signal processing means.

Abstract: A method and construction are disclosed to form a trench gate JFET transistor.   The invention comprises forming a first trench in a semiconductor substrate, forming a gate channel about the trench and forming a conductive layer upon the surface of the gate channel. The conductive layer interfaces with the gate channel to form a p-n junction.  Source and drain regions are formed adjacent to a trench and disposed in electrical contact with the gate channel.   An integral capacitor may be added to the construction by forming a second trench, which extends through and excavates a portion of the first trench.   The drain region is extended about the surface of the second trench to remain in electrical contact with the gate channel.   A layer of insulating material is applied to the second trench, which is then filled  with  a  body  of  conductive  material.  The conductive material is insulated from the conductive layer by the insulating layer.
