Abstract: METHOD AND APPARATUS FOR CONVERTING ROD STOCK OR WIRE ROD                       INTO WIRE                   ABSTRACT OF THE DISCLOSURE A method for converting rod stock or wire rod into wire comprises heating of the rod stock or wire rod, high speed rolling and cooling thereof, and final slight drawing to make the surface thereof smooth and finished. The high speed rolling is carried out by a rolling mill having a lightweight construction and roll stands comprising three rolls at 120° from one another. Two of the rolls are rotatably supported by shafts which have eccentrical ends. Two spindles having eccentrical ends engage with their ends corresponding seats in the ends of the shafts,so that rotation of the spindles provides rotation of the shafts and axial displacement thereof in order to adjust the rolling pass.

Abstract: CLOSED LOOP SENSOR CONDITION DETECTOR                 ABSTRACT OF THE DISCLOSURE           An electronic control unit for regulating the air/fuel  ratio  of  an  internal  combustion  engine  is disclosed.  The electronic control unit has an open loop calibration  for  regulating  air/fuel  ratio  that  is corrected with a closed loop signal developed by an inte-gral controller. The integral controller bases the closed loop correction signal on a signal from an exhaust gas composition sensor located in the engine exhaust manifold. Various conditions of the system are sensed by a closed loop sensor condition detector to provide information on whether the sensor is up to operating temperature and is operative. If the exhaust gas sensor is functioning and the operating system parameters indicate the system opera-tion  should move  to closed loop control,  the loop is closed by the condition detector.  Included in the condi-tion detector circuit is a timer whose cycle is RPM depen-dent.  The timer will time out if the sensor has not indi-eated an operational capability in one timing cycle or a set number of RPM counts and will generate a signal indi-eating  a  sensor  failure.  After  closing  the loop,  the detector circuit will check for a sensor transition on a periodic basis related to the authority of the integral controller and provide a signal to open the closed loop if the transition does not occur. A rich burst generator is provided to perturbate the loop periodically to produce a rich  transition  of  the  sensor  if  it  is operable.   A latching  failure  indicator  circuit  is  additionally included in the system to energize a visual indicator and alert an operator if the failure condition occurs.

Abstract: ABSTRACT OF THE DISCLOSURE:          Mounting device for panel elements, especially for buildings and the like.  It includes a number of mounting bars mounted on the surface to be covered by the panel elements which are provided with a number of mounting ribs for cooperation with the mounting bars.  The object is to provide a simple device of this kind, which device allows mounting without requirement for accurate alignment of the different details.  This is accomplished in that each mounting bar carries a number of retaining members for cooperation with the mounting ribs.  The retaining members are locked against movement perpendicularly to the longitudinal axis of the mounting bar but are freely slideable along the mounting bars to enable adjustment of the retaining members relative to the mounting ribs.  Each retaining member includes two jaws facing each other, the jaws being bent outwardly at an angle to the mounting bar and at their outer ends being connected by means of a connecting member which is bent to define an upwardly open and in the initial position of the jaws substantially trapezoidal recess, in which the mounting rib fits and which, when the panel element is pushed inwardly, closes around the mounting rib, so that the jaws retain the same.

Abstract: ABSTRACT          A process for producing foodstuffs, beverages and forages with a reduced content of biogen amines and preferably with a reduced content of histamine is des-cribed. People with good health are able to degradate histamine which they take up with food by a histaminase. Nevertheless, many people,fe/male and male, are not able to perform a sufficient degradatlon of the histamine and if these people take up histamine this results in severe troubles, like headache, a development or gastric ulcera, diarrhoea. as well as several kinds of allergic  reactions.          If histamine is present in forages, like e.g. in silo-fodder, then the histamine passes over into the milk and accordingly also into the diary products, so that it is desired to have not only foodstuffs but also forages available with low histamine levels or completely histamine free.          It now was found out unexpectedly that foodstuffs, beverages and forages having a drastically reduced histamine content or being completely free of histamine can be pre-pared by adding during any desired step of the preparation of the foodstuff, beverage or forage a microorganism which performs a transamination or desamination of histidine, or an enzyme which results in a transamination or desamination of histidine. According to said process the histidine can e.g. be converted by a primary splitting off of ammonia into the innocuous glutamic acid.          The new process is especially important for the production of such foodstuffs, beverages or forages, in which an essential step in the course of the preparation of said products is a conversion performed by a micro-organism like e.g. an alcoholic fermentation or a lactic fermentation. The naturally occuring microorganism strains generally perform a decarboxylation of histidine present in the starting material forming the undesired histamine. The new process makes it possible to produce such food-stuffs, beverages and forages which generally have a high histamine content, like e.g. alcoholic beverages, sour-milk products, pickled cabbage and silo-fodder, nearly or completely free of histamine.

Abstract: Abstract of the Disclosure A temperature sensitive resistor is immersed in a bath of quench oil and is supplied with electrical power sufficient to keep the resistor at a predetermined and substantially constant temperature above the vaporization point of water. When water is present in the oil, the water is vaporized by the resistor with the vaporization acting to cool the resistor and lower its resistance value.          A signal which varies as a function of the drop in the resistance value of the resistor is produced and causes an increase in the power supplied to the resistor so as to keep the resistor at its predetermined temperature.          In addition, transient pulses in the signal are detected and an alarm signal is produced when there is sufficient water present in the oil bath to cause the time-average value of the pulses to exceed a predeter-mined threshold. The resistor is protected from turbulence in the oil bath by a small chamber which contains a test sample of oil and which is periodically purged to bring a new test sample into the vicinity of the resistor and to allow the resistor to momentarily be exposed to air in order to clean slime and tar from the resistor.

Abstract: ABSTRACT OF THE DISCLOSURE        Natural gas taken from a gas well is loaded continuously and at a preselected, generally uniform rate into a movable separate pressure vessel means until such is filled with a discrete batch of natural gas at a pressure in excess of 55.384 kg/sq.cm. (800 psia), where-upon it is replaced with another separate pressure vessel means, with no interruption of gas flow.  The filled, movable vessel means is then transported to an off-loading terminal.  Well shock is thus controlled, and maximum natural gas recovery obtained.  A generally uniform flow rate is obtained by a regulating valve, when well head pressure exceeds about 800 psia, and by a compressor when the well head pressure is below such value.

Abstract: Abstract A waveform storage system is provided in which wave-form envelopes or maximum signal deviations along a waveform are detected and stored. A sampling clock operates at a pre-determined fixed rate independently of a recording clock which is operable at rates determined by the sweep speed and is equal to or slower than the sampling clock. Data from an analog-to-digital converter is simultaneously applied to at least one latch and at least one comparator to be compared with the latch output. If the absolute value of the signal is greater than that stored in the latch, the latch is up-dated with the new value. The contents of the latch are clocked into memory by the recording clock.
