Abstract: Abstract of Technical Disclosure Color photographic products and processes are disclosed which provide a silver image in registration with a light-transmitting screen composed of minute optical elements, such as an additive color screen.  The silver image is present in the developed silver halide emulsion layer which is maintained in registered relationship with said screen on a transparent support.  Where the silver halide emulsion is negative-working, the silver image is a negative of the photographed subject, and the thus-obtained additive color negative image may be used to form full color positive images by printing onto subtractive color print material.      The undeveloped silver halide may be allowed to remain in the developed silver halide emulsion layer, or all or a portion thereof may be removed form the developed silver halide emulsion layer.  If desired, undeveloped silver halide may be transferred to a silver-receptive stratum carried by a separate support to provide a positive silver transfer image which may serve as a "proof" of the developed negative image.

Abstract: ENGINE BRAKE HORSEPOWER TEST WITHOUT            EXTERNAL LOAD                   Abstract Apparatus for and method of determining the brake torque and horsepower of an internal combustion engine without connecting an external load.  Means are provided to operate the engine at full throttle and with all but one out of n of successive ignitions inhibited, the value n being selected so that the engine operates with just enough power to equal the frictional load of the engine and main-tain an equilibrium speed at the upper end of the engine speed range.  The engine is then operated momentarily with full ignition, and then with no ignition, during which a determination is made of the rate at which the engine decelerates through the equilibrium speed.  The decelera-tion rate is multiplied by the known inertia of the engine to determine the friction torque of the engine at the equilibrium speed.  The friction torque is multiplied by n - 1 to predict the brake torque of the engine at the equilibrium speed when operated normally with external load.  Horsepower is determined by multiplying torque and speed.

Abstract: RELEASABLE HOOK     ABSTRACT              In the mooring of ships and boats to a dock, it is neces-sary to have a line run from the ship or boat to the dock. The line can be more or less tight and must be fixed so as to allow relatively little movement of the ship or boat with respect to the dock. Then, when it is necessary to allow the ship or boat to sail away from the dock, it is necessary to disengage the line from the fastening means on the dock. This invention relates to a fastening means whereby a line can be positioned to the fasten-ing means for securing the ship or boat adjacent to the dock. Then, the person on the dock can mechanically actuate the fasten-ing means to allow the line to slip away from the fastening means and also to allow the ship or boat to sail away from the dock. This fastening means is identified as a releasable hook. When it is desired to have the ship or boat fixedly secured with respect to the dock, the fastening means is in a locked position to firmly position the line. Then, when it is desired to allow the line to be slipped and to allow the ship or boat to sail away from the dock, the operator on the dock can quickly and easily disengage the fastening means, or releasable hook, from the line.

Abstract: ABSTRACT            Posts, such as roadside delineators and sign supports are mounted upright from the ground by tubular anchors driven into the ground from their leading ends and having fins on their trailing ends embedded in the ground adjacent the surface thereof.  A break-away support tube is secured in the tubular anchor to extend upright therefrom into a rigid but yieldable plastic tube with an elastic memory. The plastic tube carries a reflector, a sign, or the like at a level above ground which will attract the attention of drivers of vehicles on the roadway.  The break-away tube is pierced at ground level just above the ground anchor so that when the plastic post is struck by a vehicle, the break-away tube will fracture at ground level permitting the plastic post to be forced to the ground without flying loose from the ground anchor and without springing back to damage the vehicle.  The tubular ground anchor can receive an extension tube driven Into the ground ahead of the leading end thereof to provide additional anchoring capacity in light soil ground conditions.  The lower end of the break-away tube is wedged or clamped in the tubular ground anchor and the lower end of the plastic post is wedged or clamped on the break-away tube. When the break-away tube is fractured by vehicle impact, the entire assembly is reusable to reinstall the post in its upright position by discarding the section of the break-away tube below the fractured level and using the remaining tube length in the anchor and post.  If the plastic tube has been bent or idented by the impact blow from the vehicle, it will soon recover its original straight tubular shape due to the elastic memory of the plastic.   A new hole is then pierced in the break-away tube at ground level to form another fracture zone for accommodating another impact blow from oncoming traffic.
