Abstract: There is disclosed a system of fixtures for use with standard dimension lumber for constructing pitched roofs for residential or commercial wood frame structures including gabled roofs, hip roofs and more complex roof structures. One form of sheet metal fixture takes the uncut ends of a pair of two inch (nominal) thickness lengths of lumber and is so shaped that the two lengths of lumber are joined with the fixture and common nails at a selected angle corresponding to the desired angle between rafters at the peak of a gabled roof. Other disclosed fixtures are shaped to join a hip rafter with one or more common rafters or jack rafters. Similar fixtures are used to join valley rafters with jack rafters. Further plate fixtures secure the lower ends of rafters to the plate on top of the exterior wall frame without the necessity for an angle cut or bird's mouth cut in the rafter.

Abstract: Device for measuring the speed of a fluid in a tube which comprises two uasonic electro-acoustic transducers in the tube; means for energizing these transducers by first and second transmit pulse groups; means for receiving first and second receive pulse groups at the transducer output; means for measuring a first delay between the start of the first transmit pulse group and the start of the first receive pulse group and a second delay between the start of the second transmit pulse group and the start of the second receive pulse group; and means for measuring a third delay between the starts of the first and second receive pulse groups. The flow rate is proportional to the quotient of the third delay by the product of the first and second delays. These delays comprise an integer delay part which is measured by clock pulses counting and fractional delay parts which are measured by constant current integrators.

Abstract: A toy car adapted to travel on a track assembly is disclosed. The toy car includes a motor coupled to a drive train which drives the car forwards regardless of a direction of rotation of an output shaft of the motor. The drive train includes a first set of gears coupled with a first one-way clutch to drive an axle of the car when the output shaft of the motor rotates in a first direction. The drive train also includes a second set of gears coupled with a second one-way clutch to drive the axle when the output shaft rotates in a second direction. The first set of gears represent a higher gear reduction ratio from the output shaft to the axle than the second set of gears whereby a speed of the forward motion of the car may be altered by reversing the direction of rotation of the motor. The motor of the car draws electric power from the track assembly.
