Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a method and apparatus for guiding endless woven fabric belts such as are used on paper making machines.  One of the problems with such belts is that, during operation, they tend to drift off center so that guide means have to be provided to maintain them centered on the machine.          The traditional approach is to provide a guide roller in a low tension portion of the endless belt. However, this solution is expensive and the action of the roller is slow especially on slower operating machines.  The instant application provides a novel method and apparatus for guiding the endless belts and keeping them centered.  Specifically, the instant application teaches the use of a guide shower, which is disposed across the width of the endless belt, to provide the guiding action.  The shower comprises a series of nozzles which are adapted to be directed at one edge or the other of the endless belt.  Three separate embodiments are disclosed. In one of the embodiments, the shower pipe connecting the nozzles is divided into a left side and a right side.  The nozzles on the left side are all directed at the left edge of the endless belt whereas the nozzles on the right side are directed at the right edge of the endless belt.          In a second embodiment, two parallel shower pipes are disclosed, the nozzles of one of the shower pipes all being directed at the left edge of the endless belt, the nozzles of the other pipe all being directed at the right edge of the endless belt.  In a third embodiment, a series of swivelling nozzles are mounted on the shower pipe.  The direction of the nozzles is adjusted in response to signals from a sensing device so that all of the nozzles on the pipe are pivoted towards one or the other of the edges of the endless belt.

Abstract: POLYCARBONATE MEMBRANES AND PRODUCTION THEREOF     ABSTRACT OF THE DISCLOSURE     Polycarbonate membranes useful for hemodialysis are fabricated from polyether-polycarbonate block copolymers by a water gelation process. The process comprises casting on to a substrate surface a layer of a multicomponent casting solution comprising the copolymer dissolved in a water-miscible organic solvent together with a cosolvent which acts as a swelling agent for the copolymer, drying the layer to partially evaporate the solvents therefrom, immersing the partially dried layer in water to form a gelled membrane, and stripping the gelled membrane from the substrate surface.  The membrane has improved strength and improved permeability to solutes in the "middle molecule" range while maintaining clinically acceptable ultrafiltration rates and clearance of low molecular weight solutes.

Abstract: ABSTRACT OF THE DISCLOSURE         A time averaging circuit which increases signifi-cantly the signal to noise ratio of a received signal. The output of a multiplier which provides near D.C. signals with the noise is fed to a metal core transformer through an operational amplifier.  The secondary winding output of the transformer is partly subtracted from the input in the operational amplifier, enhancing the D.C.-like signal components.  Time integration via the feed back loop results in the A.C. noise components being relatively reduced in amplitude.  The A.C.-noise components from the secondary of the transformer and the output of the operational amplifier are subtracted in a second operational amplifier, the output signal of which has substantially increased signal to noise ratio.  A pre-processing circuit includes a multiplier which multiplies the received signal with a narrow band-width portion thereof, tuned to the signal frequency, which enriches the near D.C. energy.

Abstract: ABSTRACT      A massage device has a rocking member, a synchronous electric motor drive, an elastomeric pivot, a drive connecting member, a rigid structure supporting said pivot and massge elements on the rocking member which move in opposite direction during the rocking motion. Opposed gripping means are supported by the rigid structure and are grippable at the location of minimum motion thereof to minimise the vibration transmitted to the operator. The device may also be weighted so that the moment of force ablut the elastomeric pivot is sufficient to cause slowing of the motor when the massage members act on the body and increased pressure on the gripping means lowers the frequency of the massage elements. A weight, adjustable in position with respect to the elastomeric pivot, is located in the rigid structure in opposed relation to the drive connect-member; movement of the weight causes change in the amplitude of the massage elements.

Abstract: "PNEUMATIC TIRE"                 ABSTRACT OF THE DISCLOSURE      This disclosure relates to a pnuematic tire having a rubber tread and a cast, fabricless, elastomeric body of a material having viscoelastic properties.  The ratios of the structural stiffness of the mid-sidewall of the tire body to the structural stiffness of the shoulder of the tire body and the crown of the tire body, and the tire body's resulting shape, are critical to give a durable, stable, long-wearing tire.  These ratios yield a tire which has acceptable growth levels in its cross-sectional dimension on inflation and service and which has the crown area of the body functionally decoupled from the sidewall area so that the crown area functions in a manner similar to the belt of a radial ply tire.

Abstract: ABSTRACT OF THE DISCLOSURE Alternating voltage for energizing an adjustable speed a-c motor is derived from unipolarity input voltage by means of electric power inverting apparatus comprising at least one pair of alternately conducting controllable electric valves.  The conducting states of these valves are periodically switched by a control which is responsive to frequency and amplitude command signals, whereby the frequency and the amplitude of the fundamental component of the alternating voltage are varied as functions of the respective command signals.  The control provides a triangular wave for obtaining interception points for deriving pulse width modulation (PWM) of the alternating voltage so long as the amplitude command signal does not exceed a predetermined reference value (which is less than 1.0 per unit) and the speed of the motor does not exceed a predetermined reference speed.  The control additionally pro-vides a "transition" PWM mode of operation whenever the amplitude command signal exceeds its reference value or the motor speed exceeds said reference speed. As disclosed herein the transition PWM mode is provided by a dual a-c level set scheme in which the lower level is varied as a function of the higher level so as to minimize selected harmonics of the alternating voltage and the higher level is varied as a function of the amplitude command signal thereby to vary the amplitude of the fundamental voltage component.  A smooth transitioning to a square wave mode of operation is made as the amplitude command signal approaches 1.0 per unit.
