Abstract: ABSTRACT OF THE DISCLOSURE    Mechanism for supplying golf balls fully automatically to tees of a driving  range, exactly and without delays, for each of several players practising simultaneously, according to the driving of the golf balls by the players.  An inclined main flow path is connected to a ball reservoir, and several inclined branch flow paths are connected in parallel to the main path.          There is a first vane valve within a ball discharging device, that opens and closes the main flow path, and a second vane valve within each of several flow change-over devices that opens and closes the paths from the main to the branch flow paths.  A parallelogram link within a ball serving device, connected to the branch flow paths, raises each ball to a position where it can be driven.  An electric eye detects if a ball is present on a tee or not.  When balls are short in a branch flow, an electric signal is made to a control circuit by the operation of a ball level inspection device.  There are electromagnetic solenoids for activating the first and the second vane valves, and for activating the parallelogram link; a switch in the inspection device and a photo-electric relay, activated by the electric eye, are connected in an electrical circuit.

Abstract: ABSTRACT OF THE DISCLOSURE A relay which measures sudden increases in the pressure of gas located above the fluid dielectric in elec-trical apparatus.  The relay includes defeating apparatus which prevents the operation of the sudden pressure relay when the sudden increase in gas pressure is caused by abrupt changes in the fluid level due to physical disturbances outside the apparatus enclosure.  One arrangement includes a switch which is activated, when a float on the surface of the dielectric fluid is raised sufficiently, to prevent energization of the sudden pressure relay.   Another arrange-ment uses two sudden pressure relays which are located at diagonally opposite corners of the apparatus tank and are serially connected so that both relays must be activated at the same time to energize the associated control or alarm circuits.  Other arrangements use baffles and multiple opening tubes to prevent false activation of the sudden pressure relay by keeping the fluid away from the gas opening of the sudden pressure relay.

Abstract: ABSTRACT OF THE DISCLOSURE In a reactive metal-water electrochemical cell, an alkaline elec-trolyte containing organic additives which reduce the parasitic direct cor-rosion reaction between the reactive metal and the water of the electrolyte. More particularly, the additives substantially reduce the activity of the water by forming inter-molecular hydrogen bonding between the organic additive and water.  Illustratively, such organic additives include alcohols, nitrogen containing compounds such as amides, amines and hydrazine, and ketones, ethers and esters.  Optionally, molarity of the electrolyte is controlled independent of water additions by chemically removing the reactive metal ions formed during discharge of the cell.  This is accomplished by the controlled additions of precipitating agents to the electrolyte to form insoluble salts.

Abstract: ABSTRACT OF THE DISCLOSURE         A belt feeder gate for use in self-unloading ships of the type in which the hold of the ship is provided with a hoppered bottom including a plurality of hoppers overlying an unloading conveyor belt moving lengthwise of the ship.  Each open hopper bottom is closed by a gate comprising two wheeled gate sections which are movable relative to each other along stationary tracks in a horizontal plane and in a direction laterally of the direction of travel of the underlying unload-ing conveyor belt.  The respective longitudinally opposite wheeled ends of the respective gate sections project in under-lying relation to longitudinally spaced "hog ridges" defined by the walls of adjacent hoppers, each "hog ridge" being an inverted V-shaped hollow space defined beneath two upwardly converging oppositely longitudinally inclined walls of two longitudinally adjacent discharge hoppers.  The stationary tracks on which the wheeled gates move are also in underlying relation to, although not within, the respective "hog ridges," and the hydraulic rams which impart movement to the gate sections are housed within the "hog ridges."  A further feature of the construction is the V-shaped axial cross-section of the wheels on the gate sections, which V-shaped cross-section rides on an inverted V-shaped track to prevent "play" or wobble of the wheeled gate relative to the tracks, thereby providing a constant and stabilized linear relation of the wheeled gate relative to the power means such as a hydraulic ram, which imparts movement to the gate sections.
