Abstract: Abstract of the Disclosure A start-up circuit for a power supply used in a television display  controls the operation of the power supply during a start-up interval.  The power supply is disabled by the start-up circuit at a first voltage level until a capacitor is charged to a predetermined second voltage level.  The power supply is then enabled, disabling the start-up circuit, and discharging the capacitor  The power supply continues to operate until the capacitor is discharged below an intermediate voltage level at which point the power supply is disabled and the start-up circuit again becomes operative to allow the capacitor to recharge.

Abstract: Seal and Seal Assembly Abstract A seal has a body, a leg and first and second sealing areas.  The seal is used in a seal assembly having first and second members such as, for example, a frame portion and steering knuckle of a work vehicle.          Apparatus such as a bearing supports the knuckle in rotation relative to a king pin of the frame portion.          Foreign matter can enter between the frame portion and steering knuckle and interfere with vehicle steering.          In the assembly, the sealing surfaces contact substan-tially perpendicular surfaces of the frame portion to block passage of foreign matter to the bearing .  A second end portion of the seal leg can be controllably deflectable in order to permit overfill of lubricant to pass from the bearing cavity between the frame portion and steering knuckle.

Abstract: AN IMPROVED HEAT INSULATED PISTON ASSEMBLY         AND METHOD OF ASSEMBLING              Abstract of the Disclosure An improved heat insulated piston assembly for an internal combustion engine and a method of assembly.  The improved piston assembly includes a piston constructed of a sleeve having an interference fit about a heat insulated core.  The core has a first end positioned flush with an end of the sleeve and has a second end located within the sleeve with a concave configured cavity formed therein.  Mating in the concave configured cavity of the core is a connecting rod having a spherical ball shaped end.  The spherical ball shaped end is securely held in the cavity by a retaining ring which attaches to the piston sleeve. The retaining ring allows for limited movement of the spherical ball shaped end of the connecting rod in the cavity while providing a means for returning the piston to its bottom position during the intake stroke.

Abstract: A b s t r a c t The device monitors the electrical field present in the earth, by means of at least two electrode buried in the earth. The electrodes are connected through a shielded lead to a filter FL followed by a differential amplifier (DA), a triggering circuit and an alarm organ. The circuitry of the device is dimensioned so as to detect preferentially pulses of less than a second duration and an intensity of 5 to 50 mV/m between the electrodes, and/or pulses with 1 to 30 minutes duration and an intensity of 40 to 400 µV/m between the electrodes. These two kinds of pulses occur generally a few minutes, and several hours before an earthquake, respectively, so that the time of the latter can be predicted with sufficient accuracy From an empirically determined relation between the strength of the pulse at a measuring site and the parameters of the earthquake (as epicentral distance, magnitude etc.) it is possible to predict the epicenter and the magnitude of the impending earthquake from measurements at more than three stations.

Abstract: POLYIMIDE RIBBON AND METHOD FOR THERMAL PRINTING Abstract This invention comprises a resistive layer of a thermal transfer medium which is a mixture of a thermosetting polyimide and a thermoplastic polyimide with a particulate conductive material, which may be graphite.  The resistive layer of blended polyimides is advantageously laminated to a very thin layer of silicon dioxide which provides heating properties near the printing area.  The thermosetting polyimide is commercially available as a liquid in a high-boiling organic solvent system.  The thermoplastic polyimide is commercially available as a solid, and is known to be readily soluble in tetrahydrofuran (THF) and many other organic solvents.  A blend of the two with appropriate solvents and filler of particular conductive material such as graphite is solid to the touch within 60 seconds at room temperature.  After subsequent treatment at elevated temperature to set the thermosetting resin, a thermal ribbon is achieved having the necessary physical integrity and exceptionally good resistance to degradation during use in the thermal printing process.  The element is strong and abrasion resistant, and has electrical resistivity well suited to the thermal printing.

Abstract: ABSTRACT           The invention relates to a method of coating an inductive stabilization ballast (1) with an insulating layer and to a stabilization ballast (1) coated with the aid of this method.  The ballast serves to stabilize the current through a discharge lamp.  According to the inven-tion, the ballast (1) is immersed, together with a syn-thetic resin cover (10) covering plug-in contact sockets (4 and 5), in a bath (31) of hardenable liquid insulating material.  After this immersion, a looped suspension member (12) - which was used during the immersion - is broken from the synthetic resin cover (10), as a result of which the electrical plug-in contact sockets become accessible again.  In this method, it is prevented that the plug-in contact sockets (4 and 5) are coated with insulating material.

A compression spring is arranged to bias apart the sup-ports longitudinally of a fixated limb.  In use the fixator is applied to the limb with the fracture in slight compression.  Exercise of the limb then pro-duces varying degrees of fracture compression stimulating bone callus formation and rapid healing.
