Abstract: The invention relates to a composite fabric which will provide insulating properties in the presence of water and which will also permit the passage of perspiration therethrough. The fabric includes a first layer of a waterimpermeable insulating material, two layers of a wicking fabric, such layers being positioned adjacent the inner and outer surfaces of the first layer, and a plurality of wicking threads passing through the first layer and securing the wicking fabric layers to the first layer. The insulating layer helps prevent water from reaching the wearer. Perspiration from the wearer is picked up by the inner wicking layer and transferred by capillary action through the threads to the outer wicking layer from which it can evaporate to the atmosphere. If desired the outer wicking layer can be covered by a liquid-water impermeable but water-vapour permeable material.

Abstract: ABSTRACT OF THE DISCLOSURE    A method for controlling the braking of drive wheels for a vehicle to brake drive wheel braking means in response to the occurrence of the slipping state of the drive wheels comprising the steps of performing a predetermined braking force in braking means in response to a manual operation before the vehicle is started, and gradually reducing the braking force of the braking means in response to the starting operation of the vehicle before the slip of the drive wheels is detected.  Thus, this method can suppress the drive torque of drive wheels by applying a predetermined braking force to the drive wheels at the initial time of starting by means of driver's manual operation and gradually generate the drive torque after starting to smoothly start the vehicle.

Abstract: ABSTRACT     In a relational database management system  interactive error-handling means comprises means for calling an operation means and a fetch means.  The fetch means operates against a cursor to retrieve a record occurrence noninteractively for operation.  The operation means validates the selected operation and can set an error condition signal.  When the selected operation is valid,  the operation is performed and the operation means provides a return signal to the calling means, which calls the fetch means to retrieve the next record occurrence.  When the selected operation is invalid, the fetch means responds to the error condition signal by operating interactively to display the previously retrieved signal with an error message.  The interactive user can correct the error so that noninteractive operation can continue.
