Abstract: A fuel flow measuring system for measuring the flow rate of the fuel in an aircraft and including a turbine flow transmitter which is inserted in the fuel line of the aircraft and produces an output frequency representing a functional relationship to the volume of fuel passing through the flow transmitter, the functional relationship being referred to as the K factor. A control circuit receives the output frequency and converts it into a DC valve representing the flow rate of the fuel. The flow rate is then displayed on an indicator such as a flow meter. A resistor is located in the flow transmitter and is electrically coupled to the control circuit. The resistor is set at a value to compensate for variation in the functional relationship whereas a temperature sensor, also inserted into the transmitter and electrically coupled to the control circuit, serves as a temperature compensator.

Abstract: An improved clamp is disclosed in which a carrier plate is mounted slidably within a housing and is moved in one embodiment in a linear direction by means of an actuator. First and second arms are mounted in the housing and in angularly oriented guide slots within the carrier plate whereby, when the actuator moves the carrier plate, the arms move so that jaws at the ends of the arms converge at a clamping position. A pin in each arm is engaged in its own slot in the housing to insure that the jaws move along a predetermined path. In one embodiment of the invention only one of the arms is movable and the other arm is fixed. In a second, self-centering embodiment of the invention both arms move towards each other and equal and opposite bending stresses are induced in the arms which bend the arms within the elastic limit of the metal.

Abstract: Flat bottom bags are formed from a supply of substantially endless plastic tubing, gusseted along two sides to form a flat reel. A sleeve of predetermined length is withdrawn from the reel and allowed to hang along a vertical plane between two foraminous plenum chambers which are then moved toward each other to squeeze the length therebetween. Simultaneously a sealing and shearing mechanism forms a transverse seal and cuts the sleeve length from the reel, the gussets being at the same time sealed in the seam. The plenum chambers are then subject to vacuum and are moved apart, causing the sides of the now formed bag to separate opening the same. Upon opening of the bag, a forming mandrel is inserted therein and moved through the length of the bag until it reaches the sealed end. Simultaneously a presser member is moved across the outside surface of the bag folding over the seam, and pressing the gusset portions into flat flaps and in addition forming simultaneously the flat bottom to the bag.

Abstract: The patented prosthesis device of U.S. Pat. No. 3,813,699 is effectively limited in its drifting movement deeper into its cooperating acetabular opening, which could cause rupture of the acetabular floor, by a laterally oriented lip, even though the size of the lip, in and of itself, is not physically capable of this performance. This is achieved by providing an initial clearance position to the lip and thus allowing a settling movement in the device before the lip is permitted to contact bone structure. During said settling movement, favorable secondary tissue changes occur in the acetabular opening which impede movement; thus, said tissue changes together with the lip making contact with bone structure hold the device in position, whereas premature contact of the lip would have merely indented or otherwise adversely modified the bone structure and interfered with achieving this result.
