Abstract: Electric mass and force measuring apparatus which includes two force transducers, one of which provides an electrical output signal which is proportional to the gravitational force acting on the mass to be determined, and the other providing an electrical output signal which is proportional to the gravitational force of a known mass. A signal processor responds to both of the electrical output signals and provides an output signal which represents the unknown mass. The force transducers are of the type which respond only to a force component acting in a predetermined direction, and are supported in a common frame in a manner which insures that the predetermined directions of the transducers are parallel to each other. The force transducers are preferably of the beam type and include a beam which is freely deflectable at one end and rigidly secured to another beam which extends freely to the side of the first-mentioned beam, while also being shorter than such first-mentioned beam.

Abstract: A method and apparatus are provided for measuring quantitatively the amount of liquid and convection heat emitted from a surface by diffusion. When the surface is a derm surface the transepidermal water loss is measurable by a cylindrical shield device in which one open end is engaged with the derm layer and the other open end is exposed to the surroundings and within the cylindrical shield are placed a pair of temperature transducers and a pair of humidity transducers respectively positioned orthogonally to the derm surface at first and second known distances therefrom. The temperature and humidity readings at these two distances from the surface of the derm are processed by a circuit device to calculate the amount of water evaporated per surface unit over a given time interval.

Abstract: A winding assembly for a vehicle safety belt system is provided with a belt rolling device and a high speed turning device adapted upon actuation of a propellant charge to wind the safety belt at high speeds as a result of the generation of pyrotechnical gases.

Abstract: The invention provides a belt locking arrangement for a passive safety belt system for automobiles in which the belt lock is movable along a guide on the inside of a vehicle door by an auxiliary power drive, connected to the lock via a flexible push-pull member that runs in a guide sleeve in a wall of the door, and which has a slot through which a transporter slide, connected to the push-pull member and the lock, extends. When operated the lock engages with the lock tongue rigidly fixed to the body of the vehicle.
