Abstract: A curtain for a dock shelter that is easily assembled alone and as part of a dock shelter. The curtain includes a sheet that has a pocket mounted thereon. The pocket is adapted to receive a flexible stay and include a slit that inhibits movement of the stay within the pocket. In another aspect, the invention relates to a method of making a curtain. The method includes the steps of securing a pocket to a sheet; forming a slit in the pocket (e.g., by cutting the pocket); inserting a flexible stay into the pocket; and positioning the stay adjacent to the slit. The invention also relates to a method of making a vehicle shelter and mounting the shelter to a loading dock. The method includes the steps of mounting a frame to the loading dock; securing a pocket to a curtain; forming slits in the pocket; inserting a stay in the pocket adjacent to the slit; and placing the curtain against the frame.

Abstract: A vehicle shelter comprising a head frame, a head curtain attached to the head frame, a side frame, and a side curtain attached to the side frame. The head frame includes a head subframe having a first raked channel adapted to be mounted to a loading dock wall, a plurality of cross channels attached (e.g., clinched) to and extending outward from said first raked channel, and a second raked channel attached (e.g., clinched) to said cross channels. The head frame further includes a head panel attached to an upper surface of said head subframe to form a barrier to the elements, and a head curtain mounted to the head frame. The side frame includes a side subframe having a first long channel adapted to be mounted to a loading dock wall, a plurality of cross channels attached (e.g., clinched) to and extending outward from said first long channel, and a second long channel attached (e.g., clinched) to said cross channels.

Abstract: A torque wrench has a battery-powered sensing circuit which produces a torque signal proportional to the level of the torque applied. A reference signal corresponding to a predetermined torque level is subtracted from the torque signal to produce a difference signal which is, in turn, compared with a compensation signal which is proportional to the rate of change of the torque signal and is produced by differentiating the torque signal. When the value of the difference signal exceeds the value of the compensation signal, an indicator is triggered to produce a tactile indication, the indication being produced prior to the time that the torque signal reaches the reference level by a predetermined time period.

Abstract: An electronic torque wrench has a hollow handle portion in which are disposed a DC motor mechanically coupled to the handle portion with a mass eccentrically mounted on its shaft, a control circuit for the motor and a battery for powering the motor and the control circuit. A strain sensor on the wrench produces an output signal when the torque applied to a workpiece equals or exceeds a predetermined torque level for causing the control circuit to actuate the motor to vibrate the handle portion and provide a tactile indication to the user.
