Abstract: A novel force measuring device of simple design is provided with complementary stop surfaces protecting the device against over-loading. Alternatively, overloading is prevented by duplicating the force measuring device with two portions operating in opposite directions of force application. Such force measuring devices are advantageously incorporated in couplings between a motor driven vehicle and a further vehicle to be coupled thereto. Signals derived from these force measuring devices are used in a board computer for controlling the operation of the motor driven vehicle and the further vehicle coupled thereto.

Abstract: Fluid density measuring apparatus and method for directly measuring fluid density or indirectly measuring force, acceleration, flow velocity, differential pressure and other parameters affecting the apparatus. The apparatus includes a bellows and a generally rigid hollow housing having openings through which fluid may flow to the interior of the housing, and a vibratory single-ended tuning fork mounted in the housing. The apparatus also includes circuitry for causing the tines of the tuning fork to resonate, for example, 180 degrees out of phase in a transverse direction, with the frequency of the tines varying with variation in the density of the fluid surrounding the tines. Circuitry is also included for determining the frequency at which the tuning fork tines resonate. When the density of the fluid into which the housing is placed changes, the frequency of vibration of the tines of the tuning fork is caused to change to provide a measure of the density change.

Abstract: A load cell in the bottom of a storage tank measures the weight of bulk material contained in the tank. The load cell has a flexible diaphragm to which the weight of the bulk material is applied. The flexible diaphragm moves down away from a neutral no-load position under the weight of the bulk material applied to it. A source of fluid under pressure is connected to a cavity in the load cell housing on a side of the diaphragm opposite the side that senses the weight of the bulk material. Fluid pressure is supplied to the cavity in an amount that causes the diaphragm to move to its neutral position, balancing the load applied to the diaphragm from the bulk material. A control valve senses when the diaphragm returns to its neutral position to interrupt fluid pressure supplied to the cavity. A pressure gauge coupled to the cavity senses the amount of fluid pressure required to balance the load. A reading is taken from the pressure gauge when the load applied to the diaphragm is balanced. In one embodiment, the pressure gauge is calibrated to read in feet of bulk material, which can be converted to a weight measurement knowing the cross-sectional area of the tank and the density of the material.

Abstract: The sensor includes at least one pressure chamber that is filled with an incompressible fluid, a membrane that forms at least one wall of the pressure chamber, a pressure transducer measuring the pressure within the pressure chamber, and a pressure arm whose first end is secured to a machine tool member at a location at which force and torque are to be measured and whose second end bears on the membrane. By appropriately choosing the number and disposition of pressure chambers, membranes, and pressure arms, output signals from the corresponding pressure transducers are related to selected components of transverse force torque, and axial force of the machine tool member. Various embodiments of the sensor for use with machine tools having a rotating tool and machine tools having a stationary tool are disclosed, and techniques are described in which these embodiments can be used to determine the angle between transverse force exerted on the machine tool member and a stationary axis of the machine tool, to determine the plane of transverse loading of the transverse force, and to compensate the pressure measurements in accordance with the determined plane of transverse loading.

Abstract: A pressure responsive sensing device includes a housing defining a chamber. The chamber is filled with a non-compressible fluid and is closed at one end by a diaphragm. The diaphragm is retained in position by a cover plate. A stem connected to the outside of the cover plate projects through a bearing passage and has an outer end exposed to receive a force. A force on the end of the stem is transmitted via the plate and diaphragm against the fluid in the chamber. The pressure in the chamber, in turn, is transmitted ,o an electronic transducer sensing device through a constricted passage in the wall of the housing.

Abstract: An assembly apparatus and method for use in the manufacture of strain indicators of the type in which a window and an indicator area are provided in a fluid filled capsule. Movement of the indicator area with respect to the window gives a visual indication of the load condition of the indicator. The assembly apparatus comprises means to provide for the initial placement of the fluid filled capsule into the tensile member of the strain indicator. Thereafter a compressive force is exerted on the capsule in order to bring the indicator area of the capsule in close proximity to the window with the tensile element in a relaxed condition. Following initial assembly the apparatus of this invention exerts a tensile pull on the tensile member of the strain indicator which causes the indicator area of the capsule to be separated from the window. Gap measuring means are employed to measure the distance between the window and the indicator area with the tensile element in a state of tension. Subsequently, adjustment means are utilized to adjust the gap to a predetermined value at load. The capsule is then fixed to the tensile member and the strain indicator is ready for use.
