Abstract: ABSTRACT           A speed-responsive engaging mechanism adapted for use in a hydrodynamic device to couple turbine and impeller members including a disc secured to the turbine member having a series of cam surfaces thereon formed in apertures in the discs with a series of friction shoe assemblies mounted in the apertures in engagement with the cam surfaces.  The friction shoe assemblies engage with the impeller at a predetermined speed of rotation of the turbine member, and the cam means induces a wedging engagement of the shoes with the impeller member. Spring means are provided to retain the shoe assemblies in the apertures, and a roller mechanism is provided in each shoe assembly to provide relatively frictionless relative movement between the cam surfaces and the shoe assemblies.  Each shoe in the assembly is made of a sintered metal material and has a spring retaining structure cast in the shoe.

Abstract: ABSTRACT:             A video disc player is provided with a safety mechanism which ensures that a cover cannot be opened when a main motor which drives a video disc has not been braked to a safe speed, in that an unlatching member for the cover during the time that the  main motor is being braked is retained with the aid of the safety mechanism and is not released until after braking. The safety mechanism comprises an electric safety circuit with an electric safety magnet which after  the movement of the unlatching member is energized by a supply current which is generated by the main motor, so that the safety magnet attracts a safety armature which is connected to the unlatching member as long as the motor speed is still too high. If desired, the supply current generated by the main motor may also be employed for energizing an electro-magnetic brake magnet with the aid of which a brake shoe is applied to a brake disc.

Abstract: ABSTRACT OF THE DISCLOSURE         Engine BMEP being a major contributor to the gap between conventional automobile road fuel mileage and the theoretically possible, indicates the desirability of a continuously variable road wheel/engine speed ratio.  There is described a double swash plate, regenerative, hydrostatic system, with a mechanical bypass.  The two swash plates facilitate optimization of hydraulic parameters as well as engine BMEP and the rear one which is the primary controller permits modulation of regenerated energy in both directions, with optimum efficiency and facility.  A complete electronic control concept is enhanced also by this arrangement.         Combined with a mechanical bypass and engine/accumulator parallel or independent operating capability, the system promises considerable economy and good automatic-like drivability.

Abstract: ABSTRACT OF THE DISCLOSURE         Here, a means is to be created with which quick alterations in the signal behavior are grasped and displayed.  Even with the use of peak value meters with very large time constants, such quick alterations are also to be used for the quick correction of the peak value display.  In an examplary embodiment, each separately registered current or voltage value from an individual current or, respectively, voltage circuit is compared at a comparator specifically allocated to it with a mean value which is formed from the current or, respectively, voltage values of all participating cur-rent or, respectively, voltage circuits  Upon nonequality of the current or, respectively, voltage values with the mean value within a predetermin-able limit, the output signals of the comparators are then brought to dis-play at a separately allocated display element.  The invention is used part-icularly for the measurement of the peak value of middle frequency currents in middle frequency current circuits in electomedical interference current therapy.

Abstract: BACKUP ELECTRODE AND RECORDING MEDIUM  ALIGNMENT GUIDE ARRANGEMENT FOR AN       ELECTROSTATIC RECORDER                   ABSTRACT OF THE DISCLOSURE           A backup electrode arrangement comprises a resislient insulating member across one surface of which are a plurality of electrode segments separated from one another and comprising an electrically resistive  material forming a shoe.  The electrode shoes provide pressure engagement against an array of recording electrodes in an electrostatic recorder with a recording medium disposed therebetween.  The electrical resistivity of the shoes is sufficiently high to protect the recording electrodes from pinhole shorts in the dielectric  layer of the recording medium.  With the backup electrode positioned directly opposite to the recording electrode array, the charging path impedance is reduced permitting reduction in writing time and a corres-ponding increase in overall recording time.           A recording medium alignment guide at the development station automatically seats and adjusts for proper tolerances relative to the developer fountain assmebly to properly guide the recording medium from the recording station through the development station maintaining the recording medium at the proper height above the surface of the developer fountain assembly.

The use of pyri-dine-sulfonic acids or pyridine-carboxylic acids - which results in the same good reaction rate and yield as the use of pyridine in the preparation of phthalocyanine dye-stuffs - avoids the considerable drawbacks occurring in the processes on an industrial scale, which drawbacks are caus-ed by the toxic properties and the unpleasant smell of the pyridine.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for simulating waveforms utilized to check the operability of a remote display device.  The apparatus includes a waveform generator for providing electrical signals representing simulated waveforms.  An interface circuit for coupling the waveforms to the remote display device includes a bridge network having a plurality of resistive legs in which a variable resistance element is provided in one of the legs.          The variable resistance element is coupled to the waveform generator.  An excitation signal from the remote display device is coupled to an input of the bridge.  The electrical signals from the generator causes the resistance of the variable resis-tance element to correspondingly vary and provide simulated waveforms at the output of the bridge network to the remote dis-play device.  According to another aspect of this invention, the device simulates both electrocardiographic and blood pres-sure waveforms, with the beginning of the blood pressure wave-form being delayed from the beginning of the electrocardiographic waveform so that the waves are provided in a timed sequence cor-responding to waveforms that would ordinarily be supplied by a live patient.  An interconnection device is also supplied for coupling the simulator device to a blood pressure monitor, with the interconnection device automatically compensating for signal variations between a variety of blood pressure monitors so that the simulator device can be universally employed.
