Abstract: A rotary displacement device which can be a spherical internal combustion engine, comprising a housing having a generally spherical cavity therein; a displacement member with generally spherical inner and outer configurations mounted within the cavity in the housing; and a drive mechanism including a drive shaft with a nutating member mounted thereto at a spherically shaped mounting portion positioned within the inner spherical configuration of the displacement member. The drive mechanism, displacemnent member and spherical cavity all share a common, fixed, center point. The displacement member travles in an arc within the cavity such that the axis of the arc passes through the center point. The displacement member drives the nutating member through a defined movement path which path passes through the center point. The nutating member drives the drive shaft in a rotational path the axis of which passes through the common center point.

Abstract: An integrated plumbing system comprising a plurality of interchangeable and interengagable parts which is especially useful in conjunction with boats or other marine vessels. The plumbing system includes a through-hull unit, a mounting unit, a ball valve and a plurality of components useful therewith. The components, including the valve, are made of a strong, non-corrosive, non-metallic material, in particular, a plastic-type material known as MARELON. The valve and associated components and fittings provide various configurations of units which are adapted to numerous plumbing requirements. The mounting unit permits close-coupling of the system to provide enhanced lever ratios in the event accidental side loads are applied to the system.

Abstract: A lock assembly is provided which contains a spring-loaded dead bolt and a spring-loaded plunger intercoupled to one another. The assembly is such that when the door is closed, the plunger is pushed in by the striker plate on the door frame, and this releases the spring-biased dead bolt and causes the dead bolt to be fully extended into the cavity in the striker plate. When that occurs, the linkage coupling the assembly to the doorknob moves to a position in which one of its members serves as a stop to prevent the dead bolt from being forced back to a retracted position until the doorknob is turned.

The mount includes clamping elements adapted to be secured to the supporting rail and carrying a threaded securing post, one clamping element has a cylindrical end to rotatably mount an L-shaped hollow rotary member that is mounted to the cylindrical end of the one clamping element and is rotatably positioned thereto. The L-shaped member includes an outwardly extending mounting post for securing objects thereto and thereby the supporting rail.

Abstract: A resettable single-barrel single-plug cylindrical two section lock assembly is provided wherever master keying is required. The lock of the invention is intended to be operated and reset by three different keys. One key (#1 key) is used to turn the lock to a position in which it may be reset by either of the other two keys. One of the other two keys (#2 key) operates a first section of the dual lock; and the other of the other of the two keys (#3 key) operates a second section of the lock which is independent of the first section. Either section may be reset by inserting the existing #2 or #3 key into the lock once the lock has been turned by the (#1) key to a predetermined position, and then turning the lock to the reset position, and after the existing key has been withdrawn, turning the lock back to its normal operating position by the new key, either the #2 or #3 keys, depending upon which section of the lock is being re-keyed.

Abstract: A double-barrel double-plug cylindrical lock is provided for hotels, and the like, where changes of occupancy frequently occurs. The lock cylinder is constructed to be of approximately the same size and shape as the prior art lock cylinders, so that the lock of the invention may readily be mounted into existing mortise door hardware to replace existing cylindrical locks. One plug of the lock is intended to be operated by the guests' key; and the other plug is intended to be operated by the maid's key, by an emergency key and by a program key. The guest key may be used to turn the guest plug to a resettable position in which a new guest key may be inserted which sets the guest plug to accept the new key. However, the lock is constructed so that the guest plug cannot be turned to its resettable position unless the emergency key or program key is first inserted in the other plug to turn the other plug to a particular angular position in which the guest plug is able to be turned to its resettable position.

Abstract: A film strip controller for exposed and developed photographic roll film adopted to be used with a photographic printing apparatus employing a roll film strip transport drive using slip clutches, includes a magnetic brake assembly responsive to signals generated as a result of varying light intensity incident upon a plurality of photosensitive detectors. The brake assembly stops the roll film being transported through the controller with each negative image on the film strip in proper registration and locates the negative in the proper plane so the shutter of the associated photographic printing apparatus can be operated to expose a positive print of the negative. Operation of the shutter may release the brake of the controller allowing the film to continue to move through the film strip controller until stopped by the brake means for the next negative.
