Abstract: ABSTRACT          Body stimulator apparatus comprises a portable housing containing a signal generator that supplies a periodically varying treatment signal of ultrasonic frequency and given voltage and current to electrodes applied to a living body to be treated.  A retrievable record of the time of treatment is stored in digital form and the voltage and current are sensed and analog representations thereof are fed to a normally disabled analog to digital converter.  The converter is enabled by synchronizing pulses from a separate test instrument and the analog representations converted to digital form are latched and loaded into a shift register array with the stored record of the treatment time and shifted out therefrom serially to the test instrument by clock pulses generated by the latter.         The test instrument is actuatable to generate the synchronizing and clock pulses required to enable the converter and actuate the shift register, The data output from the shift register in the stimulator is stored in a shift register in the test instrument and is selected for display on a display device by actuation of one of several actuator buttons actuatable selectively to retrieve either of the analog representations of the current and voltage or the stored record of the treatment time.

Abstract: Abstract of the Disclosure Chemically treated glass fibers in the form of continuous bundles of glass fibers and chopped bundles of glass fibers are provided that have good handleability and thermal aging characteristics in reinforcing thermoplastic polymers.  The chemically treated glass fibers have a dried residue of an aqueous chemical treating composition.  The aqueous chemical treating composition has two aqueous soluble, dispersible, or emulsifiable film forming polymers which can be either epoxy polymers and polyurethane polymers or epoxy polyurethane copolymers and polyurethane polymers and an amino alkyl functional silane coupling agent and at least a second silane coupling agent which can be a lubricant modified amine organo functional silane coupling agent, a polyamino organo functional silane coupling agent, an epoxy organo functional silane coupling agent or a vinyl organo functional silane coupling agent and a reaction product process aid.  The reaction product process aid is obtained by reacting alkoxylated nitrogen-containing compound such as an alkoxylated fatty amine and an alkoxylated fatty amide with a polycarboxylic acid to produce a product which is reacted with an epoxide compound.  The amount of water in the aqueous chemical treating composition is that to give an effective solids content for treating the glass fibers.  The chemically treated glass fibers as chopped bundles of glass fibers are suitable for reinforcing such thermoplastic polymers as polybutylene terephthalate, polyphenylene sulfide, polyphenylene oxide and polyacetals.

Abstract: A B S T R A C T           An arrangement for transporting air with the aid of so-called electric ion-wind includes at least one corona electrode (K) and at least one taraget elect-rode (M) located downstream of the corona electrode at a distance therefrom. The arrangement also includes a direct-current voltage source (3), the two terminals of which are connected to the corona electrode and the target electrode respectively. The construction of the corona electrode and the voltage of the voltage source are such that a corona discharge generating air ions occurs at the corona electrode. The occurrence of an ion current flowing in a direction upstream from the corona electrode, and thus counter acting the desired direction of air transport, is prevented by effectively screening the corona electrode in a manner such that the strength of any ion current flowing in the upstream direction and the distance through which such an ion current migrates from the corona electrode is practic-ally zero, or in all events much smaller than the pro-duct of the ion-current strength and the distance mig-rated by the ion current in a direction downstream from the corona electrode. The distance from the corona elect-rode to that part of the target electrode receiving the predominant part of the ion current is at least 50 mm, and preferably at least 80 mm.

Abstract: ABSTRACT OF THE DISCLOSURE Active  pilot  wire  apparatus  for  replacing  a passive continuous metallic wire pair coupling between the electromechanical units of a conventional electromechanical pilot wire protective relay is disclosed.  For the protec-tion of a power line section, an electromechanical unit is coupled to each end thereof.  Each electromechanical unit includes  an  operating  relay  coil  which  when  energized operates breaker contacts to interrupt current through the protected power line section.  A signal representative of the potential across the operating coil of each electro-mechanical unit is transmitted through an active communi-cation channel to the other electromechanical unit where it is buffered by a high impedance amplifier.  In each case, the output signal of the buffer amplifier is representative substantially of  the  corresponding operating  relay coil potential.  An impedance element is coupled between each buffer  amplifier  and  the  other  operating  relay  coil. Current is diverted from the operating relay coil of each electromechanical  unit  through the corresponding coupled impedance element in accordance with the potential of the signals coupled thereacross.  The active pilot wire appara-tus may be extended to  the coupling of a plurality of electromechanical  units to form  a  current  differential protective relay operative to protect against faults in a corresponding plurality of sets of power lines with each set constituting a current path of a power system network.

Abstract: ABSTRACT          "IMPROVEMENTS IN DIRECTIONAL DRILLING OF A               DRILL STRING"      A method of controlling the direction of a drill bit (3) at the downhole end of a drill string (2) drilling from a surface comprises providing two steer-able stabilisers (4,5) at the downhole end of the drill string (2)  at locations spaced apart in the drilling direction, and adjusting the orientation of the stabilisers to create reactive forces from the bore hole (6) to deflect the course of the bit (3) in a desired direction.  The stabilisers (4,5) are suitably arranged eccentrically and circumfertially offset by 180° ? 60°.  In normal drilling the drill string (2) is rotated such that the stabilisers (4,5) engage the bore hole (6) to support a downhole motor (1) against tilting  When off course drilling is sensed the stabilisers are rotated to a position and stopped from rotation such that drilling forces generate reaction forces to cause a desired change of direction.
