Abstract: ABSTRACT OF THE DISCLOSURE     A provisional holographic lens Hl is recorded by causing the interference of a parallel reference beam with a divergent beam emitted from an optical fibre 27, and then a definitive holographic lens H2 is recorded by causing the divergent beam reconstructed by illuminating the provisional holographic lens by the reference beam to interfere with the beam emitted by an optical fibre 31. The definitive holographic lens H2 and the ends of the fibres 27 and 31 are embedded in a block of hardenable transparent synthetic material.          The provisional holographic lens Hl may be positioned externally of this block or be enclosed with the other elements in this same block.         This process in particularly advantageous, because it permits certain delicate optical adjustments to be eliminated and because it avoids certain causes of light loss.     Figure 1

Abstract: SAFETY CLOSURE DEVICE     ABSTRACT OF THE DISCLOSURE A safety closure device for use in dispensing flowable material from containers. A base member is attachable to the container, and has an up-standing neck through which extends a dispensing bore. A closure cap is mounted on the neck and is rotatably and axially movable thereon. Move-ment is accomplished by means of a pair of tabs which are shielded by the base member except when rotated into alignment with a pair of recessed portions in the base member. Only when the tabs are rotatably aligned with the recessed portions can the closure cap be axially moved to uncover a dispensing opening, In a more complex embodiment of the invention, a second rotation of the closure cap is necessary after the axial movement is accomplished in order to uncover the dispensing opening.

Abstract: ABSTRACT OF THE DISCLOSURE     A cementing head apparatus for injecting a cementing plug into a well casing.  The apparatus comprises a head unit, manifold unit, and a tubular mandrel slidably mounted within the manifold unit. Prior to injecting a cement slurry into the well casing, the cementing plug is mounted in the head unit and held in place by a shearable O-ring.  During the cementing operation, part of the slurry stream flows through the head unit below the cementing plug, and part of the slurry collects in a "head" space above the plug.  This arrangement provides an equal and balanced pressure force on opposite sides of the plug to prevent premature injection of the plug into the well casing. When the desired amount of cement has been pumped, the mandrel is moved to a position which cuts off the cement flow and diverts another fluid only into the space above the plug.  The resulting loss of pressure below the plug and maintenance of pressure above the plug shears the O-ring and allows the plug to follow the slurry into the well casing.   28,446-F

Abstract: RING GROOVING APPARATUS FOR USE WITH A PACKAGING MACHINE OR THE LIKE                   Abstract of the Disclosure An improved multi-station machine is disclosed for assembling ring-type closures from generally cylindrical paperboard cylinders and generally circular paperboard discs.  The machine employs a rotatable dial plate, carrying eight mandrels and an improved ring clamping system, which dial plate is incrementally rotated by an automatic indexer assembly relative to the various operating stations which consist of a ring feed station, a disc feed station, an adhesive dispensing station, a curling station, a grooving station and a closure ejecting station. Means are provided for controlling the operation of the various stations so that they operate in substantial synchronism with one another and with the rotatable dial plate.  The improved disc feed station automatically feeds the lowermost disc from a stack of discs to a position over a ring on the dial plate and simultaneously forms a peripheral skirt on the disc and positions it in an open end of the ring.  The adhesive dispensing station employs a pair of tube pumps to dispense adhesive and lubricant on partially  assembled  ring-type  closures.   The  grooving  station automatically forms a peripheral groove and a corresponding radially inwardly extending rib in the cylindrical wall of an assembled ring-type closure.   The closure ejecting station provides vacuum means  for withdrawing a completed closure from a mandrel on the dial plate and pressurized air means for assisting in the automatic removal of the closure from the mandrel and for automatically propelling the thus removed mandrel from the machine.  The ring feed station provides means for preventing the introduction of rings onto the dial plate in response to an indication of insufficient discs at the disc feed station.  Control means are provided for manually indexing the dial plate as well as prevention of disc feed, and adhesive and lubricant dispensing if an appropriate ring is not present on the dial plate, as well as control means for preventing ring feed if sufficient discs are not available at the disc feed station. Various other control features are disclosed for the prevention of operator injury, material waste and machine jamming.

Abstract: Abstract A detector monitoring the voltage ripple in the rectified electrical output signal of an alternator in a multiphase alternator battery charging system is dis-closed.  A circuit monitors the undulating alternator output signal and produces a signal level in response. To correct the detector operation for various magnetic phenomena present in the alternator, a first circuit measures the rotational speed of the rotor and produces a proportional signal.  A second circuit determines the excitation current supplied to the field coil.  The measurement and determination are separately weighted and combined to form a corrected comparison threshold value.  A variable threshold circuit combines the signal proportional to the rotational speed of the rotor and the determined field coil excitation current to produce a combined signal level.  Comparison means compare the signal level from the monitored alternator output signal with the combined signal level and produce an output sig-nal level indicative of the detection of a voltage ripple in excess of the combined signal level.  The output sig-nal is corrected for the effects of significant alterna-tor performance characteristics.
