Abstract: ABSTRACT OF THE DISCLOSURE          A spiral wrapping apparatus provided with a mechanical closure device is used to tie the leading and trailing edges of a film web which have been overwrapped around a plurality of vertically stacked units to form a unitary package.  The leading edge of material from the film dispenser is held by a clamp mechanism to a turntable. As the turntable is rotated to wrap the load, the wrapping material is stretched and the trailing end of the material is formed into a rope-like configuration which is carried on the mechanical closure device to a position adjacent the clamped leading end of material with the leading and trailing ends then being tied together. The turntable clamp mechanism releases the leading end of the film web, extends away from the edge of the turntable and clamps the trailing end of the material web behind the tie point at which time the trailing end is severed by a cutter device between the tie point and the clamp mechanism, allowing the tied ends of the wrap to be carried forward toward the wrapped load by the memory of the stretch material seeking its original state.  The turntable clamp mechanism then is transported back toward the turntable edge drawing with it the new leading end of material with which to begin the next wrapping cycle.

Title: Immunoassay with fluorescent label excited by luminescent reaction
Inventor: CAMPBELL ANTHONY K
IPC: G01N21/64

Granted: 1982-01-12
Abstract: ABSTRACT         The invention relates to a method of detecting, analysing, quantifying or locating a protein, antibody, antigen, hapten, hormone,. metabolite, nucleic acid or steroid, in which the substance of interest is linked to a chemi-luminescent or bio-luminescent label. luminescent reaction is then triggered by the addition of an oxidising agent or a catalyst and -the emitted light is observed in order to provide information about the substance.   The invention employs a luminescent reagent which consists of antibodies labelled with a luminescent material such as luminol.   The luminescent reagent can be used to quantify antigens in an immunological assay. The luminescent labelled antibodies selectively bind to the antigens and the amount of light emitted in a luminescent reaction gives an indication of the amount of antigens present.   A luminescent labelled substance can also be reacted with an antibody or antigen labelled with a fluorescent material in order to carry out a homogeneous assay.

Abstract: Title of the Invention HEAT EXCHANGER            ABSTRACT OF THE DISCLOSURE         A combustion air preheater for heating combustion air with heat energy provided from flue gas includes both a heat pipe type heat exchanger for effecting low temperature heat transfer between the flue gas and the combustion air and a tube-and-shell type heat exchanger for effecting higher temperature heat transfer.  The preheater includes a first heat exchanger, having first and second heat transfer compart-ments with a plurality of heat pipes extending therebetween and a second, connected heat exchanger which includes a plurality of heat tubes supported by tube sheets within a shell. Ducting is provided to direct flue gas over the tubes of the second heat exchanger and then through one of the compartments of the first heat exchanger and additional ducting is provided to direct combustion air through the other compartment of the first heat exchanger and through the tubes of the second heat exchanger.  Heat energy is transferred through the walls of the tubes in the second heat exchanger to the combustion air in a first, higher temperature range with additional heat energy transferred to the combustion air in the first heat exchanger in a second, lower temperature range through the heat pipes.  The preheater advantageously uses the heat pipes in the lower temperature range and the tube-and-shell heat exchanger in the higher temperature range to effect high overall preheater thermal efficiency over a wide temperature range with minimal corrosive attack on the heat exchange surfaces.

The attenuator includes a counter which provides a binary output count representative of the desired attenuation.  An input applied to the counter can cause a stepwise increment or decrement to the output count of the counter.  A control circuit responds to the binary output count in order to produce an attenuation control signal.          Attenuation circuitry, coupled within the transmission channel is controlled by the attenuation control signal in order to apply the desired amount of attenuation into the channel.  The attenuation circuit can be a resistance pad having sections each of which are switched into and out of the transmission channel by relays responding to the counter binary count output.

Abstract: TITLE: ANCHOR                              ABSTRACT        An anchor is provided with a fluke pivotally attached to a standard.  A latch mechanism controls movement between the fluke and standard and is released upon application of a force in a predetermined direction.  The standard is then free to pivot to a position in which the fluke and standard are aligned.  This facilitates removal of the fluke from the sea bed.  Sprags are provided on the rear of the fluke so that dragging of the anchor along the sea bed causes the fluke to rotate on the standard and be repositioned for engagement with the sea bed.  Thus the anchor is able to reset upon the tide or wind changes.  The latch includes a bar extending along the standard and having a follower running in a cam track on the fluke.  The cam track is stepped to provide a stop that limits relative movement between the fluke and the standard until the direction of pull of the anchor rope moves the bar and lifts the follower clear of the stop.  Reset is provided by a lost motion device that allows the bar to move over the stop.
