Abstract: ABSTRACT A liquid level control system for controlling the flow of liquid into a reservoir, storage tank or other container. A nozzle develops a liquid flow stream therethrough, and a valve effectively opens and closes the nozzle. A fluid amplifier is associated with the nozzle and includes a fluid power stream, a signal developing port for receiving a fluid pressure signal from the power stream, and a sensor for diverting the fluid power stream from the signal developing port in response to the static presence of the interface at a predetermined sensing level of liquid in the reservoir. A pressure responsive switch is coupled to the valve and is located below the signal developing port of the fluid amplifier. A pressure signal tube communicates between the signal developing port and the pressure responsive switch to create a hydrostatic pressure head above the switch to maintain the switch and, therefore, the valve in a first condition when the fluid power stream delivers a fluid pressure signal to the signal developing port. A second condition is developed when the fluid power stream is diverted from the signal developing port.

Abstract: Abstract A method of seismic exploration of the subsurface of the  earth   Seismic  reflection  data  are  gathered  in  a selected  area.   The  seismic  data  are  combined  with available   non-seismic   data   to   define   an   initial two-dimensional lithologic model.  Based upon the initial model, a set of synthetic seismic data is generated.  The degree  of  correspondence  between  the  set  of  synthetic reflection  data   and  the  gathered   seismic  data   is determined.      The    initial    model-parameters   are systematically  perturbed  during  a  series  of  iterations until  a  desired  degree  of  correspondence  has  been achieved, resulting in a final lithologic model.

Abstract: Abstract of the Invention A central elastic ring having elastic loops attached to opposite sides.  The loops are of suffi-cient size to insert fingers on opposite hands into them whereupon when the hands are spread away from each other the elastic ring enlarges for being set on the root of a penis.  When released the ring con-tracts to act as a check valve for enabling blood to be massaged into the penis and to prevent its outflow to thereby obtain and maintain an erection.  An accessory provides for mounting the elastic ring on a rigid sleeve which can be fitted over the penis so the elastic ring can be slid off at the root of the penis.

Abstract: LOCKING TROLLEY FOR HANGERS Abstract of the Disclosure A locking trolley (10) for gripping and locking the hooked ends (26) of hangers (20) in a garment bag (14) includes a C-shaped frame member (30) and a jaw member (40) extending forward from the rear of the C-shaped frame member.  Gripping pads (60, 62) for gripping the hooked ends of the hangers are located between the lower horizontal portion (52) of the C-shaped frame member and the jaw member.  A locking arrangement operatively moves the jaw member toward the lower horizontal portion of the frame member to cause the gripping pads to grip the hanger ends and also locks the jaw member in the hanger gripping position. The locking arrangement preferably takes the form of a locking lever (46) pivotably connected to the forward end of the jaw member.  The locking lever pivots between the jaw member and the upper horizontal portion of the frame member to hold the jaw member in the locked position.  To release the locked relationship the locking lever is grasped and pivoted between the jaw member and the upper horizontal portion of the frame member.  A lip structure (100) at the forward end of a gripping pad serves as an obstruction to the move-ment of the hangers from between the locked trolley.  A predetermined structural configuration (110, 112, 114, 116) of the gripping pad increases the compressibility of the resilient gripping pads for better gripping flexibility around the hangers.

Abstract: HEAT CURABLE POLYSILOXANE RELEASE COATINGS   WHICH STRATIFY WHEN BAKED AND PAPER           COATED THEREWITH      ABSTRACT        A heat curable coating composition which deposits a release coating containing a smaller proportion of silicone release material is disclosed.  This composition comprises (1) an hydroxy-functional resin which is preferably a polyester resin; (2) a cross-linking agent for the polyester, such as an aminoplast resin; and (3) at least one and preferably a mixture of at least two reactive silicones which are preferably polysiloxanes.  These two polysiloxanes comprise: (A) a hydrogen- or alkoxy-functional polysiloxane; and (B) an elastomeric polysiloxane reactive with the hydrogen- or alkoxy-functional polysiloxane to provide release properties.  Either or both of the polysiloxanes are reactive with the hydroxy-functional resin or the cross-linking agent. Components (1), (2) and (3) are compatible in a liquid admixture which may contain a volatile inert organic solvent or which may be solvent-free.  During the heat cure, the polysiloxanes in component (3) become incompatible with respect to the balance of the composition, and this causes stratification of the polysiloxanes to the surface of the cured coating when the composition is deposited upon a paper or plastic substrate and heated to cure the same.  The hydroxy-functional resin and its cross-linking agent go to the paper surface and fill its porosities to minimize the amount of polysiloxane needed to provide the desired release properties.

Abstract: ABSTRACT OF THE DISCLOSURE           A power servo system which includes an actuator coupled to a load and receives an input command signal indicative of desired motion at the load.   A sample-data control system receives and samples input signals indicative of desired and actual motion at the hydraulic actuator and load, and provides drive signals to the actuator necessary to obtain desired motion. The sampled-data control system includes digital processing circuitry with series and feedback compensation, coordinated with the hydraulic system transfer function, to form a complete closed-loop control system operating in the sampled-data or Z-transform domain.  Different equation constants in the series and   feedback   compensation   circuitry   are   recalculated periodically. In one embodiment of the invention, such constants are recalculated as a function of system behavior, so that system control automatically varies with operating conditions. In other embodiments of the invention, system constants are calculated based upon a single operator-variable (or remote system) input,  which accommodates rapid operator-implemented tracking of system behavior while reducing calculation time.

Abstract: ABS "Method of and circuit arrangement for evaluating the output signals of current flow detectors in telecom-munication facilities".           The flow of a loop direct current and/or a dialling alternating current can be detected in tele-communication facilities by means of current flow detectors. The output signals produced by the current flow detectors are applied to an evaluation circuit, the zero-crossing of the dialling alternating currents being used to determine whether a dialling alternating current has been superimposed on the loop direct current.          In order to increase the evaluation security and to detect noise voltages coupled into the subscriber-connecting line, the durations of positive and negative half-waves of the loop current are measured and the evaluation is effected by comparing the sum and the ratios of the measuring values to a presettable thres-hold.
