Abstract: ABSTRACT      An electrical connector assembly for establishing electrical contact between a pair of circuit elements has a pair of mating terminals each adapted to form electrical contact with a respective one of the circuit elements.  The terminals cooperate to permit the elements to be pivoted one with respect to the other along an axis of rotation, each of the terminals having a generally plate-like contact portion defining a contact surface oriented substantially normally to the axis of the rotation.  The contact sur-faces are biased together in rotatable electrical interengagement.  A multi-piece dielectric housing receives said terminals with each supported in a respective housing piece.  The housing pieces are joined together for pivotal movement one with respect to the other.  The joining means includes a pair of trunnions formed integrally with one of the housing pieces and a yoke formed integrally with the other housing pieces for receiving the trunnions.

Abstract: Abstract Electrostatic air cleaner apparatus is disclosed for use in conjunction with existing space conditioning apparatus which includes a transformer providing a low voltage (typically 24VAC) power signal.  The apparatus includes a power supply which is adapted to be coupled to the output of the transformer for providing a low voltage DC power signal.   A high voltage generator and regulator is included which is powered by the low voltage DC power signal.  The generator and regulator includes a flyback transformer arrangement which generates a high voltage DC signal suitable for energizing the collector and ionizer stages of an air cleaner assembly.  The generator and regulator also includes closed loop feedback for regulating the amplitude of the high voltage DC signal so that it remains at or near the optimum amplitude regardless of variations in the amplitude of the low voltage power signal supplied by the existing low voltage transformer.  The apparatus also includes an air cleaner assembly to which the high voltage DC signal is applied.

Abstract: ABSTRACT OF THE DISCLOSURE           A particle fuel burning furnace has an upper combustion chamber for holding a pile of particle fuel and  burning  the  same  from  the  bottom  thereof.  The furnace  also  includes  a lower combustion chamber for afterburning combustible gases given off by the burning of  solid  fuel  in  the  upper  chamber and a series of spaced apart vertically-extending passageways  arranged in  a  row  and  interconnecting  the  upper  and  lower chambers  for communicating the combustible gases from the upper to the lower chamber. A first improved feature relates to a particle fuel delivery control device which operates an auger for filling  the upper chamber with particle  fuel  to a desired level. A beam of light is transmitted and reflected between a photoelectric cell and  reflector  respectively  of  the  device.  When  the particle fuel pile has grown in height during filling to the  desired  level  the  light  beam  is  interrupted and filling is terminated. A second improved feature relates to  a particle  fuel  diversion structure positioned in space  relationship  above  and  overlying  the  row  of passageways. The structure forms a horizontal slot which extends  laterally from  the passageways which prevents particles of fuel from falling through the passageways and relocates  the flame which burns the particle fuel pile  from  the  bottom  to  a  region  away  from  the passageways.

Abstract: Abstract of the Disclosure A method is described of filling and sealing a popcorn package.  A flexible bag is provided which may be formed from flexible sheet material such as paper having longitudinally extending gussets in which the in-folded portions of the gussets approach each other closely to divide the bag into a pair of collateral tubes communicating together along a central line.  The bag is held in an upright position with one of the tubes in a collapsed state while the other is expanded.  The expanded tube has a smaller cross section than the other tube.  A charge of fat and corn is introduced into the tube of smaller cross section through its open top.  Preferably, a means is provided for collapsing the tube of smaller cross section transversely at a point below the center of the bag but above the bottom end of the bag to maintain the charge at the center of the bag and in the smaller tube.  The bag is then sealed.  During popping in a microwave oven, microwave energy is absorbed efficiently to achieve a popped volume about 10% to 15% greater than an equivalent package with tubes of equal cross section.  The popcorn passes during heating from the smaller tube to the larger tube as the bag expands during the popping operation.

Abstract: Abstract of the Disclosure A process for producing HuIFN using whole human blood and a method for assaying the blood HuIFN productivity are disclosed. The whole blood is incubated in the presence of an anticoagulant (e.g. heparin, ACD, and CPD) and a viral inducer under the conditions appropriate to accumu-late a substantial amount of HuIFN. The blood HuIFN productivity deter-mined by titrating the accumulated HuIFN with a suitable procedure (bio-assay, radioimmunoassay, or enzyme-linked immunosorbent assay) is useful in clinical test to detect cancer in its early stage. The HuIFN per se is recovered, and purified prior to its prophylactic and therapeutic uses.

Abstract: TITLE:    CONSTRUCTION TOY                           ABSTRACT      A construction toy utilizes a plurality of tubular elements which are connectable to each other or are connectable to one or more hollow members.  Each of the tubular elements has a first skirt on one end and a second skirt on its opposite end which are of the same size and are utilized to attach the elements to the hollow members.  Further, attaching to one of the skirts on one of the ends is a smaller skirt which allows the smaller skirt to be attached to one of the skirts on a further of the tubular elements so as to connect two tubular elements together.  The tubular elements have a plurality of convolutions which allow them to be expanded or contracted so as to lengthen or foreshorten the tubu-lar elements as well as allowing the tubular elements to bend during the construction of structures with the com-ponents of the invention.

Abstract: METHOD AND APPARATUS FOR FINE SHEARING               ABSTRACT OF THE DISCLOSURE        A method and apparatus for fine shearing a metal workpiece involves placing the workpiece on a stationary die surface for support and driving a single punch against the workpiece such that at least a portion of the workpiece is placed in compression.  The punch is then driven into and through the workpiece along a predetermined path which has a first directional component both perpendicular to and directed toward the die surface and a second directional component both parallel to the die surface and directed into the compressed portion of the workpiece.  The punch is driven with a force having components both perpendicular to and parallel to the path of the punch.  The force component perpendicular to the punch path is large enough to keep the compressed portion of the workpiece in a plastic state. The force component parallel to the path of the punch is large enough to overcome the shear strength of the workpiece along the path. The method and apparatus allow the formation of a variety of fine-sheared surface configurations.

Abstract: Abstract A digital video signal processing system is described wherein composite video signals are sampled by sampling clock signals phase locked to burst. The respective sampling phases of the sampling clock are encoded and concatenated with the digital video samples for storing in a FIFO memory syncrhonously with said sampling clock signals.  Reading of the stored video sginal samples and associated sampling phase codes occurs synchronously with processing clock signals phase locked to horizontal sync.  Utilization means coupled to the memory and responsive to the sampling phase codes serve to demodulate the color component of the composite video signals.
