Abstract: SKI BINDING JAW                 ABSTRACT OF THE DISCLOSURE A front jaw for a safety ski binding includes a support member mounted on a ski having a hold-down cooperable with a ski shoe sole supported for vertical movement, a pair of centering levers cooperable with the sides of the ski shoe sole supported for pivotal, movement about vertical axes, and a compensating lever supported for pivotal movement about a substantially horizontal axis.  One end of the compensating lever engages the top of the sole hold-down and the other end engages the centering levers.  A spring urges the centering levers inwardly, and the centering levers in turn urge the compensating lever pivotally so that it urges the hold-down downwardly.  When the sole hold-down is moved upwardly during a fall, it causes pivotal movement of the compensating lever which in turn causes pivotal movement of the centering levers outwardly away from the ski shoe sole against the force of the spring.          Upward movement of the sole hold-down is limited by a stop.

Abstract: Abstract:         In a speech communication system, an input speech signal is partitioned into a plurality of subband portions. Responsive to each subband portion, a signal of lesser bandwidth representative of the subband portion is generated by dividing the instantaneous phase of the subband by an integer k where k=2, for example, the center frequency and bandwidth of each subband is halved.  The lesser bandwidth subband portion representative signals are combined to form a compressed bandwidth signal representative of the input speech signal.  A replica of the input speech signal is formed by partitioning the compressed bandwidth signal into subband portions thereof; converting each compressed signal subband portion into a signal representative of a subband of the input speech signal; and combining the converted subband representative signals into a single speech signal replica.

Abstract: ABSTRACT      An antenna apparatus of the type comprising a frequency separator having a plurality of frequency-selective reflecting surface members for separating electromagnetic waves and two electromagnetic horns for the feeding of said electromagnetic waves is described.  Each of the surface members has a lattice in turn having a periodic pattern of conductive material and inherent resonance frequency; the inherent resonance frequencies of the various surface members are substantially equal to each other.  The lattice is capable of serving as an inductive-capacitive circuit element at a specific frequency region lower than the inherent resonance frequency and exhibiting substantially equal induc-tance and capacitance with respect to the electromagnetic waves when made obliquely incident in the transverse electric and transverse magnetic modes. The surface members are disposed to have an interactive resonance at a fre-quency lying within the specific frequency region.  The frequency separator solves a problem of prior separators, namely that incoming waves of the two different modes have different resonant frequencies if those waves inpinge ob-liquely on the separator.

Granted: 1984-11-06
Abstract: ABSTRACT     A method of removing calcium from cation exchange resin beads containing adsorbed calcium and magnesium by passing aqueous sulfuric acid, of 20 to 50% by weight concentration saturated with calcium sulfate and containing magnesium sulfate substantially below saturation, through a bed of the resin beads continuously until the adsorbed magnesium is in ion exchange equilibrium with solution mignesium, while simultaneously exchanging solution hydrogen ions for the adsorbed calcium ions.  The sulfuric acid solution becomes supersaturated with calcium sulfate and is then passed to a crystallizer where the calcium sulfate is precipitated.  The sulfuric acid solution in the crystallizer is recycled to the resin bed after precipitation of the calcium sulfate, and can be continued up to the point until at least 75% of the adsorbed calcium has been removed while the adsorbed magnesium remains in the beads.

Abstract: FIBER OPTIC ROTATION SENSOR               UTILIZING UNPOLARIZED LIGHT                         Abstract A fiber  optic  rotation  sensor,   employing detection of the Sagnac phase shift, comprises a single mode fiber forming a loop.  The rotation sensor utilizes unpolarized light to provide reciprocal operation.  The unpolarized   light   produces   incoherent   light  wave components which are averaged to zero in the detector.          Non-rotationally  induced phase shifts between  coherent components resolve into vectors equal in magnitude and opposite  in  phase  angle  so that  the  non-reciprocal components of these vectors cancel.        The   rotation   sensor   is   independent   of environmental factors when the phase difference between the waves counterpropagating through the loop is an odd multiple of  .pi.  /2.  Accordingly, the sensor includes a phase shifter for biasing such phase difference to .pi.       /2 to provide a stable operating point when the loop is at rest.  Additional compensating means are included to provide stability during rotation.

Abstract: Abstract Pulse Circuits A pulse circuit forms part of a radar transmitter in which a pulse forming network is used to generate a high current pulse at relatively low voltage and to feed it via a transformer to a magnetron which operates at typically 30 kV.          A number of pulse forming networks are connected in parallel and are discharged by respective thyristors. The outputs of the pulse forming networks are combined so as to provide a low voltage pulse (of the order of 600 volts) having sufficient power to drive a radar transmitter. The pulse form-ing networks must each be capable of handling very large currents and must have characteristics which are identical to each other. To enable these requirements to be met, each pulse forming network includes an inductor which is formed as a coiled thin conductive layer lying on the surface of an electrically insulating board. It is formed by printed circuit board techniques and a mirror image coil is formed on both sides of a double sided printed circuit board. All pulse forming networks are connected-via a common double sided printed circuit board to the primary winding of a pulse transformer.

Abstract: ABSTRACT OF THE DISCLOSURE      A longitudinally gapped, continuous slide fastener chain with sliders slidably mounted is longitudinally fed along by a feed roller through an apparatus including a top stop applicator mechanism.  When the slider on a pair of coupling element rows is sensed by a slider sensor, the feed roller is stopped and a chain stop lever is lowered into a gap adjacent to the coupling element rows.  The feed roller is rotated again to feed the slide fastener chain again to displace the chain stop lever slightly downstream by engagement with a bottom stop attached to a following length of coupling element rows.  When the slide fastener chain is stopped again, the chain deflector is lowered transversely into the path of the slide fastener chain to depress the chain so that the chain located downstream of the chain deflector is pulled back until the ends of the coupling element rows where top stops are to be applied are bought into clinching dies.  After the chain deflector has been fully lowered, a main shaft is rotated through one revolution for actuating a top stop cutter to cut a pair of top stop blanks out of a flat wire bar and lowering a curling punch to clinch top stops around the rows of coupling elements at their ends in the clinching dies.  The foregoing cycle of top stop attaching operation is repeated for successively attaching top stops to the slide fastener chain.
