Abstract: ABSTRACT         A variable inductance transducer for providing, via inductance modulation, an electrical output signal which is representative of a mechanical input signal.  The transducer comprises a cylindrical plastic bobbin on which an inductive coil is wound.  A pair of electrical terminal receiving sockets for a pair of electrical terminals are formed at one end of the bobbin and a pair of electrical terminals are disposed therein.  The ends of the wire forming the coil are soldered to the terminals.  A protective enclosure is molded around the coil and the portions of the terminals received in the sockets to enclose the coil and lock the terminals in place in the sockets. A ferrite core is slidably arranged within a central axial bore in the bobbin to vary the inductance oil the transducer in accordance with the axial position of the core.  The core is selectively positioned by means of an actuating mechanism including a flexible actuating member and in one disclosed embodiment the actuating mechanism is a vacuum servo while in another disclosed embodi-ment, it is a formed wire rod.  The transducer is of reason-able cost and possesses accuracy, repeatability and response which makes its usage in an engine spark timing control system significantly advantageous.

Abstract: ABSTRACT:           A hot-gas reciprocating engine comprising at least three piston-like bodies which each separate a hot space and a cold space in the relevant cylinder.          Each of the hot spaces communicates, via a regenerator, with one of the cold spaces in another cylinder. Each of the piston-like bodies cooperates, by way of a drive rod, with a plate which is mounted on a rotatable shaft in such a manner that it cannot rotate with respect to this shaft, but can be tilted about a tilting shaft extending transversely of the first-mentioned shaft, Each of the cold spaces communicates, by way of a duct incor-porating a control valve, with a cold space in another cylinder. Means for operating these valves are so con-structed that, when the valves are opened, these means operate the means for tilting the plate, so that the plate assumes a more inclined position with respect to the shaft. The means for tilting the plate can. be operated independently of the means for operating the valves.

Abstract: ABSTRACT OF THE DISCLOSURE            A film strip projection arrangement includes a projection optics system adapted to cooperate with a device for guiding and transporting a film strip for projection, the film strip having perforations along at least one of the longitudinal edges thereof.  The device consists of two spaced parallel plates having grooves forming a closed orbital track for the film strip, with one or more film strip entry or exit groove portions extending tangentially from the orbital track to an edge of the plate.  A driving gear engages the perforations to drive the film strip around the track for endless projection of the film strip by cooperation of the projection optics system with a film gate or window of the device.  The film strip length is a little greater than or equal to the length of the orbital track.  The device reduces possible damage to film strips, and also eliminates the need for glueing the ends of a film strip to form an endless loop.

Abstract: ABSTRACT OF THE DISCLOSURE     A velocity rate change sensitive fluid valve is disclosed.  The valve is comprised of a pendulum member pivotally supported in a reservoir of fluid.  The pendulum member is arranged to intercommunicate an input port and an output port with the fluid reservoir upon pendulous movement.      The pendulum is supported by a fixed shaft which is ported along its axis to define fluid input and output passages.  The pendulum member includes an intercommunicating passage which, upon displacement of the pendulum by a predetermined amount of rotation, as for example by an acceleration or deceleration, will intercommunicate the input and output passages of the support shaft.  Fluid flow of fluid pressure may then be communicated through the valve as as acceleration or de-celeration indicative signal.

Title: Shutter latch system with automatic release for shock  damping member
Inventor: COUGHLAN EDWARD H
IPC: G03B9/24
Filed: 1977-01-12
Granted: 1980-07-29
Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to an improvement to a photographic camera of the type having an automatic shutter latch mechanism which may be released in response to initial shutter blade movement resulting from energization of the shutter drive means and which may thereafter be moved into position to accommodate relatching of the shutter blades in response to film advancement.  The shutter latch mechanism additionally includes a shock stabilizing arrangement to inhibit the accidental unlatching of the shutter blade mechanism resulting from shutter blade movement occassioned through extraneous vibration, sudden shock, or otherwise.  The improvement resides in the automatic shutter latch mechanism which includes means responsive to the displacement of the latch when effecting the release of the shutter blade mechanism for inhibiting the operative influence of the shock stabilizing means on the blade mechanism until the blade mechanism is returned to its arrangement wherein it is retainable by the latch.

Abstract: ABSTRACT OF THE DISCLOSURE          In a compressed air operated device for driving or setting fastening elements into a receiving material, a driving piston is axially displaceable within a cylinder in the device.      Two separate supplies of compressed air are provided to the cylinder, one for driving the piston forwardly and the other for moving the piston rearwardly after the completion of the driving action.  The parts of the device forming the cylinder are arranged to provide an opening between the cylinder and the exterior of the device.  The opening is normally kept closed, however, it is opened when the piston is driven for inserting a fastening element, so that air in the cylinder ahead of the piston can be exhausted to assure the optimum displacing effect of the compressed air acting on the piston.
