Abstract: Duttweil-6 ADAPTIVE FILTER WITH TAP COEFFICIENT LEAKAGE    Abstract of the Disclosure Adaptive filters are commonly used in echo cancelers and automatic equalizers.  Usually adaptive filters include a tapped delay line and apparatus coupled to the delay line for producing a tap coefficient signal, whose sign and magnitude indicate the appropriate correction in adjusting the filter.  However, in the presence of input signals having a partial frequency band spectrum, known filters tend to become unstable, e.g., tap coefficient signals blow up.  The instant arrangement includes apparatus for weakly driving the tap coefficient signals to optimal values.  As illustrated in a deceptively simple embodiment, a tap coefficient updating component is extended through a one's complement converter to a first input of a binary adder.  A two's complement output of the adder is fed back to a second input of the adder.  The sign of the adder output is also provided to a CARRY-IN input terminal of the adder.  Functionally, a unit leak is introduced in the least significant bit of the adder output tap coefficient signal whenever the updating component and the tap coefficient signal are of opposite algebraic signs. Otherwise, no leak is introduced.  Thereby the tap coefficient signal is weakly driven toward zero.

Abstract: FLOW CONTROL VALVE          Abstract of the Disclosure A flow control valve has a slidable valve member and a variable orifice structure.  The valve member slides in response to a pressure differential, created by fluid flow through the variable orifice, to bypass fluid in a positive displacement pump.          The variable orifice is a self-contained unit including a longitudinally movable pin having a variable cross section disposed in an aperture.          The pin position in the aperture controls the size of the orifice and therefore imposes a flow restric-tion which creates the pressure differential.  The flow control valve is useful with power steering hydraulic pumps and systems where it is desirable to reduce the amount of hydraulic fluid which is delivered to the steering mechanism when the pump input speed exceeds a predetermined value.

Abstract: TOPICAL TRIETHYLENETETRAMINE - CONTAINING PHARMACEUTICAL COMPOSITIONS AND METHODS OF USE                         ABSTRACT The present invention relates to topical compo-sitions containing triethylenetetramine useful in treat-ing skin disorders.  Triethylenetetramine, or trien, has heretofore been administered orally.  Current therapy employs antibiotic or antimitotic agents for topical application, coupled with ultraviolet radiation or systemic antimetabolites in some cases, but with results which are not uniformly satisfactory.  In addition, the physical properties of the agents in the prior art cause topical preparations of those agents to be un-sightly.  Trien provides topical anti-inflammatory activity which, in combination with conventional anti-infective agents or antimitotic agents, is shown to provide improved effectiveness in the topical treatment of skin disorders and can be formulated in a clear solution or gel for pharmaceutically elegant application.

Abstract: ABSTRACT OF THE DISCLOSURE      Food is fed onto a weighing platform inside a dispensing chamber and carried by a parallelogram weighing support disposed outside the dispensing chamber and supported by means of four parallelogram arms from an upright frame, the platform being retained in a position to receive the food by a releasable latch.   When a weigh beam detects a weight set by a control circuit, it sends a signal to the control circuit which causes feed to stop and provides a condition in which a signal can be sent to the latch to release the weighing platform into a position in which a weighed portion of food can be discharged therefrom.   In one embodiment, at least one switch is manually operated from outside the unit to cause the control circuit to apply the releasing signal to the latch either immediately or after an interval of time.

Abstract: ABSTRACT An improved infant incubator is disclosed having a cylin-drical shaped transparent hood which provides considerable ac-cessibility to the infant.  The cylindrically shaped hood consists of a plurality of sections rotatable about a central axis.  The sections may be individually opened to give limited access to the infant or totally rotated to a position beneath the infant sup-port structure such that access may be had from all sides of the incubator without obstructions.  Heating of the incubator com-partment is achieved by a unique means of circulating heated air through a double wall construction of the hood.  The air is heated in a compartment beneath the infant and the warm air enters one of the hood sections and circulates through that section whereupon it is transferred serially to the next section and eventually can be received back into the heater compartment from the hood sec-tions for recirculation.  A fan and heater are located in the heater compartment for heating and circulating the air.  The double wall hood is readily disassembled and one of the walls re-movable to facilitate cleaning of all wall surfaces.

Abstract: ABSTRACT     A device, detectable by automatic means, is concealed within a spring-tong-like housing structure formed from plastic arms joined at one end by a concealed bayonet type locking arrangement that creates a non-mobile joint. The arms are sufficiently flexible to permit their free ends to be pressed together manually thereby engaging a tack shank carried by one arm in clutch lock concealed in the other arm.  The intermediate portions of the arms have reduced structural rigidity such that any attempt to bend the housing structure when the tag is closed will result in flexure of the intermediate portions absorbing the bending forces with reduced communication of shearing force to mating end portions of the arms.
