Abstract: Abstract of the Disclosure Film material for use in sterilized medical solution containers such as blood bags or I.V. bags, comprising 30 - 90% linear low density polyethylene (LLDPE) and 10 -70% styrene-ethylene-butylene-styrene (SEBS).  The par-ticular LLDPE and SEBS materials are selected from among known LLDPE and SEBS materials according to density, in the case of LLDPE, and styrene/rubber ratio and composition in the case of SEBS.  Up to 10% of an optional third component such as high melt index LLDPE or polypropylene may be added as a processing aid.  Material having greater than 50% LLDPE is particularly well suited for medical solution container application.

Abstract: CIRCUIT FOR REDUCING ERRORS IN A DATA RECEIVER     Abstract of the Disclosure In a data receiver, a complex data signal after demodulation and sampling is applied to an equalizer which provides an improved signal which is applied to a phase and amplitude correction circuit for correction utilizing a complex reference vector.  The corrected signal is applied to a decision circuit the input and output of which are applied to a difference determinator circuit, the output of which is a complex residual error signal utilized in conjunction with a plurality of gain factors generated in a gain factors generator to deter-mine the reference vector.  The gain factors vary in time from transmission initialization such that optimal compensation for transmission disturbances is achieved both at initialization and after stabilization.

Abstract: ABSTRACT OF THE DISCLOSURE         A variable-voltage variable-frequency elevator control apparatus includes a circuit for consuming regenerated power produced during regenerative braking provided on the DC side of the apparatus rather than on the AC side.  During regenerative braking with an emergency generating unit in operation, regenera-ted power is consumed by the consumption circuit on the DC side of the circuit and is prevented from being returned to the emer-gency   generating unit.  This prevents the production of voltage notches commonly produced during regenerative braking by thyris-tor commutation in conventional circuits.  Because no voltage notches are produced, a reduction in the size of the emergency generating unit can be achieved.  In addition, since it consumes DC power rather than 3-phase AC power, the consumption circuit requires fewer elements than in conventional control apparatus.

Abstract: Abstract of the Disclosure A housing has an inlet arranged to be connected to the outlet of a fuel mixing device of an internal combustion engine such as a carburetor and an outlet arranged to be connected to the intake manifold of the engine.  In a preferred embodiment of the invention, the housing has two or more spiral bores.  These bores have a cross sectional area less than the cross sectional area of the outlet of the carburetor to provide increased time and velocity through the spiral bores and to isolate the carburetor from vacuum pulsa-tions of the engine.  The defining surfaces of the spiral bores is roughened to increase atomization.  A second embodi-ment utilizes an elongated housing also having a spiral path for mixing the fuel and air.  This latter housing has a longitudinal bore which also increases the velocity of flow of fuel and air mixture through the housing and includes a vacuum controlled valve arranged upon decreased vacuum to allow direct flow of fuel to the intake manifold in bypassing relation for providing a heated area around the spiral path, such casing being arranged to be connected into the exhaust manifold for using the heat therefrom.

Abstract: BAGGAGE INSPECTION APPARATUS AND METHOD FOR DETERMINING THE PRESENCE OF EXPLOSIVES            Abstract This method and apparatus are directed to baggage inspection, and more particularly, baggage inspection to locate explosives.   In the preferred and illustrated embodiment, a conveyor system is utilized to transport a bag past a first magnet to achieve an initial nuclear magnetic resonance (NMR) polarization of a selected element.   The element in the preferred embodiment is hydrogen, it being noted that hydrogen in explosives has a long T1 and a short T2.  The first magnet provides an initial polarization.  The bag continues on the conveyor belt past a second magnet.  The second magnet provides the measurement field intensity and a coil contains an interacting RF forming the interrogation pulses.  Echoes are received.   In the preferred embodiment, first and subsequent second echoes are received and stored.  The two signals are subtracted from one another to a null.  The NMR response of elemental hydrogen in compounds typified by explosives is accented by subtraction of the two stored signals to form a response indicative of explosive materials.  The apparatus permits adjustment and to the magnetic field to accommodate distortions for metal in the baggage.

Abstract: ABSTRACT OF THE DISCLOSURE     Heat fluxmeter incorporating a row of thermistors, whose electrical resistance varies significantly with the temperature and which are arranged on the outer surface of the container for accurately measuring the temperature thereof.  The range of temperatures in the vicinity of the container is determined by means of a second row of thermistors.  It is possible to deduce therefrom the heat flux leaving the container, i.e. the power emitted by the calorigenic material contained therein.  The considerable sensitivity of this meter makes it possible to use it without excessively disturbing the thermal equilibrium so that the measurement can be carried out in a very short time.

Abstract: A LOAD SENSING HYDRAULIC SYSTEM    Abstract of the Disclosure A load sensing hydraulic system is disclosed which essentially eliminates kickback from a feedback mechanism contained in a manually operable control valve which in turn is fluidly connected to a hydraulic function.  The system includes a power on demand pump fluidly connected between a reservoir and the control valve for supplying pressurized fluid to the hydraulic function.  A load signal line is also connected between the control valve and the pump which serves to transmit pressure signals, which are generated by loads acting on the hydraulic function, to the pump for controlling the pressurized output thereof.  A load signal control valve is positioned in the load signal line and is fluidly connected to the discharge side of the pump.  The load signal control valve is capable of sensing pressure variations between the fluid discharged by the pump and the upstream fluid present in the load signal line.  As soon as the control valve senses that the pressure of the fluid discharged by the pump is less than the upstream pressure of the fluid in the load signal line, it moves to block off fluid flow from the hydraulic function and thereby eliminates kickback on the manually operable control member.
