Abstract: ABSTRACT OF THE DISCLOSURE          The signal processing apparatus described is particularly useful in a graphic arts process simulating system.  In a preferred embodiment, the apparatus makes use of a vidicon to generate a video signal in response to light signals.  A controlled iris adjusts the intensity of light signals into the vidicon in accordance with the peak value of the video signal, so that the vidicon can operate with a range of light intersities corresponding to its optimum dynamic range.  Prior to the iris adjustment, a measurement of the average video signal level is made and the resulting value stored.  The stored signal value is used in conjunction with the average video  signal level after iris adjustment to generate a pedestal correction voltage, which is used in a clamping circuit to provide an output video signal which is representative of the true characteristics of the image.

Abstract: A METHOD OF ENERGY CONVERSION AND A DEVICE FOR THE APPLICATION OF             SAID METHOD            Abstract of the Disclosure The utilizable energy of a working fluid is converted into mechanical energy by means of friction forces exerted by the fluid on the moving walls of one or a number of circulation ducts forming part of a rotor.  In their respective azimuthal projections, the friction force exerted on the fluid by the duct walls and the Coriolis force to which the fluid is subjected are of the same order of magnitude.  The method consists in varying the pressure of the working fluid which is circulated in a spiral circuit and subjected to azimuthal displacements in the same direction of rotation as the rotor when the fluid comes closer to the axis and in the opposite direction when it moves away from the axis.  When at least a portion of the duct walls forms part of a heat exchanger, the working fluid can also undergo predetermined varia-tions in entropy and in enthalpy.

Abstract: ABSTRACT OF THE DISCLOSURE        A fluid flow control system e.g. for an integrated continuous fluid reagent production facility and one or more reagent consumption facilities, involving an interconnected reagent storage facility, has fluid flow control valves connected together and sensing the demand and supply situa-tion to the consumption facilities, to provide continuous even flow of reagent either from production or from storage or both.  A main valve ensures that, whenever possible, demand for reagent is satisfied directly from production. A storage withdrawal valve ensures that, in the event that the reagent flow through the main valve is insufficient to satisfy demand, the flow to the consumption facilities is supplemented by withdrawals of reagent from storage. The fluid flow valves are              operated by signals deriving from the fluid flows and pressures at various locations in the system.  The storage withdrawal valve is fed with a bias signal derived from the rate of production of reagent in the production facility, which maintains it at its threshold opening condition when demand is being satisfied completely by flow through the main valve.  Then in the event that demand increases beyond that which can be satisfied by the flow through the main valve, the storage withdrawal valve opens immediately to satisfy the demand and maintain substantially continuous flows without deadbands or surges of reagent.

Abstract: Attorney's Pocket No. T??-78/78/369 ABSTRACT OF THE DISCLOSURE           A plural channel amplitude modulated station carrier telephone system and method wherein two a.c. signal are applied to modulated a called subscriber's channel carrier signal at a central office to signal an incoming call for the subscriber, wherein a phase locked loop is used at the subscriber terminal equipment to lock with one of the two a.c. signals following recovery of the two a.c. signals from the called subscriber's carrier signal, wherein the output of the phase locked loop is utilized to provide for the synchronous detection of the other of the two a.c. signals, and wherein a ring circuit responds to the synchronous detection of the other of the two a.c. signals to ring the called subscriber's telephone.  According to another feature of this invention, the a.c. signal to be synchronously detected is interrupted at a rate determined by and equal to the central office ringing signal frequency, and the thusly interrupted synchronously detected a.c. signal is filtered at the subscriber terminal to develop a local ringing signal voltage having the same frequency as the central office ringing frequency.  According to another feature of this invention the signal with which the phase locked loop is locked is utilized to perform a channel loop test on any selected channel in the carrier system.  Other features of this invention include a ring circuit with either a special transistor switching or relay switching arrangement to develop the voltage that is applied to operate the ringer in the subscriber's telephone.  Also disclosed is a novel synchronous detection circuit which employs a special phase locked loop for synchronously detecting an a.c. signal.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for protecting against the abrasion of pipe walls in a slurry pipeline caused by slack flow when the pipeline is operated in the batch mode, i.e., when one or more water batches and one or more slurry batches are transported through a pipeline. Pressure transducers sense the pressure at each relatively high point of the pipeline as an interface between a water batch and a following slurry batch passes that point.  When one of the sensed pressures falls below a predetermined low value of pressure, a control device actuates valves to divert the flow downstream in the pipeline through a staged choke containing flow restrictors, thus raising the fluid pressure in the water batch which then counteracts the effect of the static head of the slurry batch. The flow is redirected away from the stayed choke when one of the sensed pressures exceeds a predetermined high value of pressure, thus lowering the fluid pressure and preventing pipe wall overpressure.

Abstract: HYBRID ELECTRONIC CONTROL UNIT   ABSTRACT OF THE DISCLOSURE A hybrid electronic control unit for regulating the air/fuel ratio of an internal combustion engine is disclosed.   The electronic control unit is divided into two functionally distinct parts including an analog func-tion generator and a digital function generator.   The analog function generator receives analog signals to pro-cess efficiently by analog scaling, amplification, multi-plication, and division while the digital function genera-tor receives digital and logic inputs to process effi-ciently by addition,  subtraction, and comparison.   The analog  function generator  interfaces  with  the  digital function generator by an analog signal from a D/A con-verter and other unconverted digital output signals from the digital function generator.   Preferably, the analog function generator provides an open loop air/fuel ratio calibration based upon a speed density calculation includ-ing special condition corrections to the base calibration. Primarily,  the digital  function generator  is a micro-processor implemented closed loop integral controller pro-viding a closed loop correction signal to the open loop scheduler.  The closed loop correction signal is provided from the digital function generator by a pair of cascaded digital integrators having different authority levels and integration rates.  The cascade is formed by combining an asymmetric primary integrator waveform which has one RPM dependent ramp rate with a symmetric secondary integrator waveform which  has  a  time  dependent  ramp  rate.   The primary integrator has a smaller authority and a faster ramp rate than the secondary integrator.

Abstract: TITLE      IMPROVED STORAGE BATTERIES OF THE LEAD-ACID CLASS     AND METHODS OF MAKING AND OPERATING SAME     ABSTRACT           An  improved storage battery of the lead-acid class includes grid structures provided with grid complement means in the form of enclosure bodies of a chemically inert material selectively arranged about portions of the grid structure to pro-tectively reinforce same.  These protectively reinforced grid struc-tures, embodied in either a negative plate or a positive plate, may be utilized advantageously in making and operating the lead-acid battery, and are desirable for plates in which an active material is contained in tubes or occurs in pasted form.  The enclosure bodies may be a material impermeable to electrolyte.  Where the grid structure for a positive plate is provided with an antimony content, the enclosure bodies constitute a barrier which substantially inhibits release of antimony from all portions of the grid structure which are not in contact with the active material.  There is thus achieved a lead-acid battery having the advantages of an antimony-free battery requiring little or no maintenance on the one hand, and a battery with an antimony content in its grid structure which im-parts reinforced grid strength and long operating life under deep discharge conditions on the other hand, particularly with respect to positive plates.  Certain desirable forms of the enclosure bodies may include means whereby corrosion of some parts of the positive grid structure is inhibited by lengthening the path of sulfate ion flow to the parts where corrosion may occur.  It should be noted that the sulfate ion flow to these portions of the grid should be limited only to an extent such that no soluble lead hydrates are formed.  Battery plates may be combined with the grid complement means and when so combined may be electrochemically formed or charged in an improved manner.

ABSTRACT: "Method of producing microlenses and a coupling element having a microlens produced in accordance with this method".                 Microlenses which are easy to handle are produced by providing rotation-symmetrical recesses in a glass plate, depositing vitreous layers by means of a vapour deposition process onto the plate, until the re-cesses are fully filled up, whereafter the thickness of the coated glass plate is reduced to the original value or to a smaller value. Two lenses produced in this manner are then combined to one lens by placing the embedded lenses on top of one another by means of their flat sides.
