Abstract: Abstract This invention is an overrunning tooth type clutch which is retarder controlled.  The clutch engages and disengages two axially aligned shafts with slight relative rotation.  The retarder comprises a wrap spring which is circumferentially mounted on the driven shaft and engages the driving shaft.  Relative shaft rotation in one direction causes the spring to drag on the driven shaft.  In this mode, a force is created in the axially inclined slot through a pin on the driving shaft which causes the driven clutch member to move axially to engage the clutch on the driving shaft.  Opposite relative rotation causes the clutch teeth to separate and disengage the two clutch members for slip or overrunning.

Title: Inflation for teat cup assembly and  method of making same

Abstract: ABSTRACT OF THE DISCLOSURE      An inflation for use in a teat cup assembly for automatic milking machines employing a vacuum milk line and a pulsating vacuum line is disclosed. The inflation comprises an elongate, tubular, body member having a novel mouth-forming diaphragm at one end thereof for engaging the teat of a cow to retain the teat cup assembly from falling off the teat at the end point of milking. The mouth-forming diaphragm is formed by bonding one end of a relatively short tubular mouth-forming member to one end of the body member, wherein the mouth-forming member has a maximum cross-sectional dimension smaller than the maximum cross-sectional dimension of the tubular body member. The end of the body member to which the mouth-forming member is attached is expanded over the outer circumference of an annular expansion ring which has a diameter substantially greater than the cross-sectional dimension of the unexpanded portion of the tubular body member, so that the end of the body member is held in an enlarged circular configuration and the end of the mouth-forming member which is bonded to the body member is expanded outwardly toward the perimeter of the expansion ring. The other end of the mouth-forming member extends inwardly toward the longitudinal axis of the body-forming member, thereby forming the mouth-forming diaphragm at the end of the body-forming member. The mouth-forming diaphragm has a central opening therein which has a diameter less than the maximum cross-sectional dimension of the unexpanded portion of the body-forming member. Preferably, the body member and the mouth-forming member are made of silicone rubber material, with the mouth-forming member having a circular cross-sectional shape.

Abstract: AUTOMATIC CONTROL APPARATUS FOR CHORDS        AND SEQUENCES                       Abstract of the Invention Electronic and logic circuitry for an automatic tonal bass rhythm accompaniment feature and an automatic chord feature in an electronic organ.  Automatic bass rhythm accompaniment produces a pattern of notes based upon a tonic note selected by the instru-mentalist such that the desired musical effect is produced when the pattern of notes is combined with the notes being played by the instrumentalist.  The electronic organ has stored in a memory various rhythm patterns which can be selected by the instrumentalist by closing rhythm switches.  Electronic circuitry then causes notes for the selected rhythm pattern or patterns to be played automatically in response to the actuation of a pedal switch or keyswitch.  The automatic chord feature of the present invention provides selectively major triad and dominant seventh chords or minor triad and diminished seventh chords automatically in response to the selection of a root note by the instrumentalist.

Abstract: Abstract of the Disclosure A mixture of alkyl acrylate and/or methacrylate with an addition-polymerization initiator photopolymerizes when exposed to ultraviolet radiation in an inert atmosphere.  By adding an oxidizable tin salt such as stannous octoate, the mixture can be photopolymerized in air to a coatable visicosity, and greater tolerance of oxygen is permitted in carrying the photopolymerization to completion than could be tolerated in prior processes. The invention is primarily useful in making pressure-sensitive adhesive tapes.

Abstract: Abstract of the Disclosure Disclosed are optical data bus configurations for interconnecting terminals so that any terminal can communicate with any other terminals.  It is known to do this by connecting terminals serially using two trunk optical fibers and to connect terminals together in a star configuration using a single transmission star or reflection star.  The serial network is limited by optical loss while the star network requires more optical fiber and is more costly.  Disclosed is a serial bus which uses six fibers arranged in two groups of 3 each, the groups conducting light in mutually opposite directions.  A transmitting means in each terminal is coupled to two of the fibers in each group and terminals adjacent any one terminal are connected to a different two fibers than the one terminal.  Another arrangement disclosed uses hybrid reflection transmission star couplers.  Terminals can be connected to reflection ports of the hybrid couplers, while the couplers can be interconnected by the transmission ports thereof.  A relatively small number of fibers are required to interconnect a large number of terminals.

The end product (i.e. ifen-prodil) can be obtained according to this new process in a high yield of about 80% within 14 hours from the starting material in a single reaction container throughout the process, without intro-ducing protective benzyl group into the starting material prior to the bromination.

Abstract: ABSTRACT OF THE DISCLOSURE     A vertically movable marine working platform structure is disclosed, which includes a working platform supported for vertical movement on parallel support frames individually comprising a plurality of parallel disposed vertical chords, each two adjacent chords being connected by a number of horizontal members. The platform has recesses on its upper face which accommodate jack housings, the support frames passing through the jack housing and platform.  The support members have upper guides in the jack housings and lower guides in the platform, the guides individually having a length at least equal to the pitch of the horizontal members connected to the chords.  The guides of the working platform being of such relatively great length, horizontal forces applied by the guides to the support frame are concentrated mainly upon the hori-zontal members, concentration of loads being avoided upon portions of the chords lying between horizontal members.          The recessing of the jack housings into the platform pro-vides a robust and economical structure.

Abstract: ABSTRACT OF THE DISCLOSURE A novel heating device is provided herein.  It has a drive mem-ber rotated by the power source, and a plurality of discs secured to the drive member, the discs being rotated by the drive member.  A shell member encloses the discs, the shell member having a base member and a plurality of disc sections disposed substantially normally from the base member, each of the disc sections enclosing a portion of one of the discs, the disc sections being adjacently spaced along the base member to define an air space between each adjacent pair of disc sections, the shell member being stationary and each of the disc sections having an interior surface and an exterior surface, the shell member providing for disc oil spaces between the interior surfaces of the disc sections and the discs. Oil is adapted to circulate with-in the disc oil spaces between the rotating discs and the disc sections of the stationary shell member, whereby the oil becomes heated due to friction, the heated oil transferring heat to the shell member such that the exterior sur-face of the disc sections of the shell member becomes heated.  The utilization of a disc structure, rather than a cylindrical structure, enhances heating efficiency by providing a greater heated surface area in contact with the air flow.  Input energy efficiency in relation to heat output is substantially increased.

Abstract: Mutually Noninterfering Transcutaneous Nerve Stimulation and Patient Monitoring Abstract of the Disclosure Transcutaneous electrical nerve stimulation is applied to the patient, as though electrocardiograph monitoring is not being practiced.  The EKG signals are preprocessed through a selective sample and hold module, which performs amplification, comparison with selective frequency and amplitude standards (as by differentiation) and temporary holding of EKG signals at such time as the transcutaneous nerve stimulating pulses are occurring, as sensed against the frequency and amplitude criteria.  In the absence of transcutaneous stimulation signals, EKG signals are coupled directly through for conventional EKG processing.
