Abstract: An electronic system for controlling the extent of motion in the start and stop positions of a hydraulically driven member includes cold start compensation. The driven member is equiped with a voltage sensitive circuit which provides a voltage indicative of the position of the driven member along its path of motion. The position indicative voltage is compared with reference voltages and the resulting comparison voltages actuate switching circuitry to effect changes in the acceleration and deceleration of the driven member and to control the start and stop positions of the driven member. Hydraulic or mechanical apparatus responsive to the switching circuitry controls the motion extend and velocity of the driven member in accordance with the comparison voltages.

Abstract: A gage block set includes a plurality of gage blocks mounted within a case, each gage block having opposed gage surfaces with a nominal dimension therebetween and a known deviation from the nominal dimension. Sensors associated with each gage block sense the removal of each gage block from the case. A signal generator provides a distinct signal corresponding to which gage block is removed from the case. A memory stores the known deviation of each gage block within the case. A control unit responsive to the signal generator addresses and retrieves from the memory the known deviation for each gage block which is removed from the case, combines the known deviation with the deviations of previously removed gage blocks and outputs the total deviation to a display device.

Abstract: A process for the separation of solid and/or liquid particles from gases or solids from liquids, as well as for the separation of gases or liquids with different densities is proposed, in which a Venturi tube is used. The gas and/or liquid mixture is introduced inwards in radially symmetrical manner from the outside through the slot of an annular nozzle at a high flow velocity which, in the case of gases, extends up to the velocity of sound. The gas is subject to the action of a high centrifugal acceleration in the slot, which has a radius of curvature of approximately 1 to 100 mm.

Abstract: An acoustic playback device includes a plurality of selector bars equal to the number of recording grooves, a plurality of biased stylus-pressure releasing bars, the bars moving against the force of the associated spring as the corresponding selector bar is pushed into engagement with a stopper pin on the record disc to bring the introductory portion of the selected recording groove to a position where it can be engaged by a pickup. A latch plate is axially spaced from the reverse side of the record disc unit. An annular vertical wall is formed on the surface of the latch plate facing the record disc unit. Hooks on the stylus-pressure releasing bars engage the vertical wall when the stylus-pressure releasing bars are moved forward. Stylus-pressure releasing portions formed on the ends of the stylus-pressure releasing bars engage the stopper pin when advanced with the stylus-pressure releasing bars.

The frame includes first and second members, each having first and second spaced side rails. Interconnecting members depend from and interconnect the side rails of each of the first and second members into a rigid support structure. The first and second side rails are releasably interconnectable to form a co-planar bed support frame and are separable so as to be re-arranged in a nested pack carrying configuration.

Abstract: A conveyor lubrication apparatus includes a counter for energizing lubrication devices once for each predetermined number of cycles of the conveyor past a lubrication station. Timers energized by the counter activate control valves for a predetermined period of time to supply lubricant to parts of the conveyor as each part reaches the lubrication station. A current sense circuit detects current flow to the control valves and energizes the central lubricant supply pump to pressurize the lubricant flow lines for a predetermined period of time, at the end of which the pump is de-energized until the next control valve is energized. A pressure sensor is disposed in the lubricant flow lines to detect a low pressure level and causes the pump to be de-energized and an alarm to be activated.
