摘要： A bedroll has an appearance of a cylindrical sofa cushion, by day. When unrolled, it forms bed clothing, with sheets and blankets or the equivalent. The bedroll has at least two separate layers, which are releasably secured together by fasteners. One layer is both a blanket and a shell or outer covering of attractive material that either matches or coordinates with the upholstery on a sofa or other furniture adapted to utilize a pillow similar to the rolled sleeping bag. The other layer is a washable sheeting which may be inserted into, used, and removed from the bedroll. When the two layers are secured together, their combined visible edge has a characteristic which enables the bedding to be rolled, without appearing to be rolled bedding.

摘要： A sizing gage for use with an LVDT probe for producing an output signal representing the deviation of part dimension from a nominally ideal dimension, and a columnar display means comprising vertically arranged light emitting diodes for indicating the degree and sense; i.e., oversize or undersize, of part size deviation according to which of the emitting diodes is lighted. The probe output is an ac signal of polarity representing the degree of deviation. The probe output signal is converted to a dc voltage the amplitude and polarity of which is representative of part size deviation. The dc signal is used as a comparison base against a precision triangle wave signal to generate a squarewave the transitions of which occur at points in time related to the amplitude and polarity of the dc signal. This squarewave is compared to a reference squarewave of fixed transition time to produce a window pulse the width of which is representative of the degree of part size deviation. The window pulse gates clock pulses from a precision oscillator to a pair of decade counters to address a diode excitation matrix. The tens signal is gated to either the oversize light bank or the undersize light bank according to whether the time variable signal leads or lags the fixed time signal. Nulling and range setting circuit details are disclosed.
