Abstract: ABSTRACT OF THE DISCLOSURE         A compact electromagnetic flowmeter unit interposable between the flanged ends of upstream and downstream line pipes for metering fluid passing through the line, the unit being subject to compression by the flanged pipe ends to effect a fluid seal.  The flowmeter is constituted by a non-magnetic metal spool of high strength whose inner surface is protectively covered by an insulating liner to provide a flow conduit for the fluid.  Surrounding the spool and concentric therewith is a cylindrical housing fabricated of ferromagnetic material, the housing being formed by complementary half-pieces which include end plates that join the corresponding ends of the spool to de-fine an annular inner chamber.  Mounted adjacent the inner sur-face of the half-pieces at diametrically-opposed positions along a coil axis normal to the longitudinal flow axis are relatively thin coils which are shaped to conform to this surface to define electromagnets.  Electrodes are supported on the spool at dia-metrically-opposed positions along an electrode axis at right angles to the coil axis.  The inner chamber is filled with a potting compound to seal in the electromagnets and the electrodes.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for scrambling a television signal in which horizontal lines of the transmitted television picture are selectively inverted in accordance with the state of a pseudorandom noise generator.  In order to permit correction of the throughput gain as well as the throughput offset at the receiving end of the communication link so as to obtain a desired level of picture quality, particularly in a satellite communication system, an analog calibration signal representing both black and white levels is inserted into a horizontal line of the vertical retrace interval at the transmission end of the link.  This calibration signal is then detected at the receiving end of the link and the signal levels are adjusted as needed.  In addition, a randomly-varying key code signal for resetting the pseudorandom noise generator is randomly inserted into another horizontal line of the vertical retrace period to control scrambling.  The audio portion of the television signal is also scrambled by randomly shifting the audio carrier between first and second offset frequencies.

Abstract: TITLE:  NON-EXTRUDING INFLATABLE PACKER ASSEMBLY           ABSTRACT OF THE INVENTION An extrusion resistant expansible element is provided for use as a sealing element or packer in a subterranean well bore. The expansible element comprises an inner elastomeric sleeve to which fluid pressure is internally applied to produce the expan-sion forces.  The internal sleeve is surrounded by an annular array of elongated reinforcing slats formed of a relatively rigid, yet deformable material such as metal or a plastic filled with reinforcing material such as fiber glass.  The medial portion of the reinforcing slats is surrounded by an outer elastomeric sleeve which effects the primary seal with the well bore when the internal elastomeric sleeve is expanded through the application of fluid pressure.  Those portions of the reinforcing slats adjacent to each end of the outer elastomeric sleeve are deformed into frictional abutting engagement with the well bore, thus providing securement against any axial displacement or extrusion of the outer elastomeric sleeve due to cold flow under the long applied pressure, or excessive fluid pressure or temperatures encountered in the well bore.  In a modification, the elongated reinforcing slats are individually coated with an elastomeric material to improve the sealing of these elements against each other.

The setting signals are fed to a switching arrangement (52) designed to cause the respective setting motor to be stopped or driven at a pre-determined speed in the sense of rotation determined by the last setting signal until the next signal is received. Thus it is rendered possible to easily control a plurality of setting motors.

This apparatus further includes a cutting punch between the driver punch and the inner wall of the tubular frame portion.  When the punch holder descends, the cutting punch cuts a stop forming wire and forms the cut wire length into a stop preform in cooperation with an anvil.          As the punch holder further descends, the driver punch drives the stop preform into the tapes of the chain and simultaneously the space punch forms a space in the chain.  During this operation,  the cutting punch rises relative to the punch holder so as not to damage the tapes.

Abstract: Abstract of the Disclosure A lever actuator which may be used in an impact printer is described.  As in conventional actuators of this type an elongated electro-expansive transducer block made of a piezoelectric or electrostrictive material is connected between a base portion and a lever portion of a frame.  A power source is connected to the block to produce a reversible strain in the block thereby tending to displace the two end  surfaces of the block relative to each other.  In the conventional arrangement the block bends which degrades the block.  In the invention, the block is connected to the lever portion through a bendable plate and to the base portion through another bendable plate. Bending takes place in these plates rather than the block when the block is energized thus avoiding the degradation problem.

Abstract: Abstract:   An elevator controller uses an acceleration command signal that has as its initial value a start shock compensation torque that will offset the unbalance torque caused at the time of starting.  From the completion of elevator car acceleration to the start of deceleration, the acceleration command is gradually increased or decreased to control the motor to provide a smoother motion of the car than has hitherto been possible.  After the commencement of car deceleration a velocity command is issued that decreases with reducing distance between the car and the destination floor.

When the product is recovered, the resulting natural rubber or synthetic resin treated spurted polyolefin pulp is readily dispersible in hydrocarbons.  Because of this, the pulp can be added to cutback asphalt to form viscous compositions which can be readily sprayed, brushed and trowled with minimal pulp separation problems.

A pump means in the form of a self-expanding bellows or hypodermic syringe is connected to a third port of the multi-way valve.  By said pump means and alternating adjustment of the multi-way valve, the substance in one ampule is transferred to the second ampule, in which the two substances are mixed with each other, and the mixture is sucked into the pump means.

Abstract: ABSTRACT           The membrane of a diaphragm pump is deformable by the reciprocable armature of a cylindrical electromagnet which is installed in the interior of a plastic housing adjacent to a partition which separates the winding or windings of the electromagnet from the casing of the pump and which carries the casing as well as the electromagnet. That section of the housing which surrounds the electro-magnet is a relatively thin cylinder having circumferentially extending heat-dissipating ribs and a cylindrical internal surface which defines with the cylindrical external surface of the electromagnet a gap of constant width.  The area around the cylindrical section of the housing is unobstructed, and the housing further includes a larger section which is integral with the cylindrical section, which is rigid with a foot extending well below the electromagnet to enhance the stability of the machine, and which confines a control circuit for the electromagnet.
