Abstract: ABSTRACT OF THE DISCLOSURE A two-circuit automatic hotplate has a switch, which can be controlled both by a bimetallic strip of a power control device and by an expansion member of a hydraulic temperature sensor. The control heating system of the bimetallic strip is in series with a cooking heating system of the hotplate.         The electric power levels of the cooking heating systems are preferably selected in such a way that, wherever possible, a current of the same level flows through the control heating system for the bimetallic strip, so that the same bimetallic strip can always be used.

Abstract: ABSTRACT OF THE DISCLOSURE       A tensioning device for maintaining a predetermined amount of tensioning force on an endless drive belt for a ve-hicle accessories drive system.  A shaft is mounted in a fixed position on the vehicle engine adjacent the drive belt.  A housing is pivotally mounted on the shaft and is biased by a torsional coil spring in a belt tensioning direction.  The spring is located within an annular space formed by spaced inner and outer housing walls and is telescopically mounted with respect to the shaft.  A lever extends generally radially outwardly from the housing and an idler pulley is mounted on an end of the lever and is moved into tensioning engagement with the drive belt by the torsion spring.  One end of the spring is attached to the housing and the other end is adapted to be fixed with respect to the shaft.  The spring is placed in tor-sion and biases the lever and housing in the belt tensioning direction.  An annular-shaped elastomer member is telescopi-cally mounted on the shaft within a central housing bore and is compressed by an end plate against the shaft and housing to provide a shock-absorbing damping effect on the housing and belt-engaging pulley.

Abstract: A FUEL INJECTOR                   Abstract of the Disclosure A fuel injector for use on an internal combustion engine which includes a housing enclosing a cylindrical barrel having a bore formed therein.  The barrel cooperates with the housing to form an annular cavity therebetween.  Axially movable within the bore is a plunger and a piston which are spaced apart.  The housing also has a nozzle situated at one end which communicates with the bore for releasing fuel into the combustion chamber of the engine.  Formed within the bore between the plunger and the piston is a timing chamber and formed between the piston and the nozzle is a metering chamber.  Pressurized fluid is directed into the timing chamber, into the metering chamber and into one end of the annular cavity by passages which are arranged in the housing and in the barrel. The passage leading into the end of the annular cavity has a control valve positioned across it such that fluid pressure can be varied to that end of the annular cavity.  Arranged within the annular cavity is a cylindrical sleeve valve which is spring biased to an open position.  The cylindrical sleeve valve is movable in response to pressure variations in the end of the annular cavity between an open position allowing fluid flow into the timing chamber and a closed position preventing fluid flow into the timing chamber.          By controlling the movement of the cylindrical sleeve valve, one can control both the timing of the discharge of fuel from the metering chamber through the nozzle and control the quantity of fuel stored in the metering chamber for subsequent discharge through the nozzle.

Abstract: ABSTRACT OF THE DISCLOSURE     A guiding and braking unit for a web which passes through a processing machine, e.g. a machine for the manufacture of packing containers.  The unit comprises a roller adapted to a guide cylinder for the web, this roller being manufactured from a material with a high coefficient of friction.  The roller is adapted to be swivelled via an arm in transverse direction of the web and as a result fol-lows the web when the same is moved sideways, that is to say axially in relation to the guide cylinder. Each sideways movement, however, because of the suspension of the roller, brings about a lifting of the roller which is continuously counteracted by the pressing of the roller against the cylinder.  As a result the roller is returned automatically to a central position and in so doing, owing to friction, carries the web with it to a central position in relation to the guide cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE           A bidirectional hydraulic drilling jar includes an elongated mandrel telescopingly disposed within a body and defining spaced apart fluid chambers separated by a restricted bore portion of the body. The mandrel is provided with spaced apart positive mechanical seal assemblies engageable with the restricted bore portion to form a hydraulic dashpot to retard movement of the mandrel in each direction over a limited stroke length so that the spring tension or weight of the drill stem may become effective to deliver an impact blow when the seal assemblies move out of sealing engagement with the restriction. Back-to-back check valves are arranged to bridge the respective seal assemblies to reduce the length of stroke required to cock and trip the jar in each direction. A separate orifice or flow restricting passage is provided across the seal assemblies so that the retarding effect is independent of coacting seal surfaces between the mandrel and the jar body. Rotary driving torque and impacting in the upward direction are absorbed by a replaceable mandrel sleeve member. The positive mechanical seals include a spiral cylindrical seal ring which is backed on its inner diameter by a piston ring type seal member so that a radially expandable substantially zero gap seal is provided between the opposed fluid chambers when the seal assembly is effectively engaged with the bore restriction in the body.

Abstract: IMPROVEMENTS TO HEAT EXCHANGERS          ABSTRACT OF THE DISCLOSURE     In  a heat exchanger,  the  flowing fluid is  caused  to impinge vigorously against  the  heat conducting  walls, for the  purpose  of improving heat transfer efficiency.          Disclosed is an apparatus for and a method of making  a twisted plastic  ribbon that fits snugly in the tubes of the   heat  exchanger,  and  which   imparts  a  helical swirling  velocity  to  the  fluid flowing  through  the tube.  Efficiency is enhanced so  economically  that  it becomes practical to make an  automotive  radiator  from round aluminum tubes, provided  they are fitted with the twisted plastic ribbons;  aluminum being a much  cheaper material then  the  traditional  copper.  The  apparatus includes two sets of traction rollers for conveying  the ribbon  from the extruder.   One set of  rollers rotates to impart  the required  helical twist.   The ribbon  is heated to  above  its  critical  temperature so that the twisted shape becomes permanent.  The ribbon is cooled (by  quenching it in  water) to give it the strength  it needs  to enter  the respective  sets of  rollers.  This apparatus allows the  twisted ribbon to be produced on a continuous-production basis.

Abstract: Abstract of the Disclosure An automatic level control circuit includes a variable gain amplifier supplied with an input signal, for outputting a level controlled signal.  A detector is provided for detecting the output signal of the vari-able gain amplifier means and the output voltage of the detector is applied via a first resistor to a first input terminal of an operational amplifier which together with a capacitor serves as an integrator.  A first reference voltage is applied to the first input terminal via a second resistor.  A first diode has one end connected to the output terminal of the operational ampli-fier and the other end connected to one end of the capacitor and a second diode is connected between the other end of the capacitor and the first input terminal.  A transistor has its first and  second electrodes connected in parallel with the capacitor and its third electrode connected to the output terminal of the operational amplifier.  The output side of the integrator is connected back to the variable gain amplifier via circuitry which causes a decrease in the gain of the variable gain amplifier only when the output voltage of the integrator appearing at the output terminal of the operational amplifier exceeds a second reference voltage.
