Abstract: HEAT EXCHANGER TUBE                  ABSTRACT OF THE DISCLOSURE         A spine fin heat exchanger is disclosed in which the density of the spine fins is greater along the portions of the passes within the pattern of high flow of air or the like across the heat exchanger.  Those portions of the tubing at the bends and outside such pattern are formed with a lower spine fin density.  Such lower density outside the patterns and at the bends does not materially reduce the overall heat exchange capacity of the heat exchanger, and results in a heat exchanger where less material and time are required to form the heat exchanger without any significant loss in its capacity.  The heat exchanger is preferably formed by chang-ing the rate of feed of the tube as it feeds through the winding head to increase the amount of stretch of the spine fin strip along the zones of low density compared to the amount of stretch in the strip along the zone of high den-sity.  Consequently, the same amount of material is required for each wrap along both zones.

Abstract: "FUEL PREHEATER"          ABSTRACT OF THE DISCLOSURE         A main conduit is engaged serially with a heater hose extending from the coolant system of an engine to the in-car heater and coolant passes freely therethrough.  A fur-ther conduit concentrically surrounds the first conduit and the ends of the further conduit axe secured and sealed to the outer wall of the first conduit as by soldering, brazing or the like thus defining a relatively narrow annular passageway or channel between the two conduits.  The further conduit is connected on one side to the fuel tank and on the other side to the metering device such as a  carburetor float chamber so that all fuel passing to the carburetor, flows through the narrow annular chamber and is preheated by the heated coolant passing through the first conduit when the engine generates enough heat to heat the coolant passing through said first conduit.

Abstract: ADJUSTABLE EXTENSION FOR SOCKET WRENCHES OR THE LIKE     ABSTRACT OF THE DISCLOSURE         Extensions to socket wrench sets or ratchet wrench sets are provided in one or two predetermined lengths which are not always the most convenient length of the operation being performed.  This device provides a hollow handle en-gaging portion with internal splines and a splined exten-sion shaft slidable therein and having a tapered clamping sleeve surrounding the extension and screw threadably en-gaging the end of the handle into which the splined exten-sion slides.  A standard socket engaging end is provided on the other end of the extension.  When the clamping sleeve is loosened, the extension can be moved endwise relative to the handle and when the desired overall length is obtain-ed, the sleeve is tightened thus clamping the two parts to-gether against endwise movement with the splines preventing rotation of one part relative to the other.

Abstract: Abstract One piece  socket  (1) or pin type  (37)  electrical contacts are stamped from a sheet of resilient, electrically conductive material and rolled into a tubular body (3) having a center section (11, 39) of enlarged diameter which functions as a C spring and is radially compressed to insert or remove the contact from either the front or rear of a bore (33, 41) in a connector (31, 45). An annular groove (17, 47)  in the center section (11, 39) engages a retention ring (35, 49) in the bore (33, 41) to lock the contact (1, 37) in place and the center section  (11,  39)  bears against the wall of the bore (33,  41)  to stabilize the connection. The resilient fingers (19) forming the socket type contact (1) taper inward and then flare outward to form a funnel (21) which guides the pin (53) of a mating pin type contact (37) into a narrow neck (55) in the socket where it is wiped clean and firmly gripped. The contacts  (1,  37) may be provided with conventional termina-tions or with a self-terminating wire well having tines (25) and ribs (27) which cooperate to grip a stripped or unstripped wire which is first longitudinally pushed into and then pulled back toward the wire receiving end of the contact (1, 37).

Abstract: METHOD AND APPARATUS FOR PARTICLE      CHARGING AND COLLECTING                         ABSTRACT Method and apparatus for charging and collecting submicron particles with high efficiency. A gas stream con-taining particles to be collected flows through charging and collecting apparatus at a rate of, e.g. 10 fps.  The particles are charged by a needle-to-plate ionizer having offset rows of needles which are spaced from the plate such that voltage gradients of 6 KV/cm and higher are achieved.  Needle-to-needle spacing and effective area of the plate are such that a corona current having a density of at least 4 ma/m2 flows between the needles and the plate.  Circuitry is provided that in combination with the ionizer quickly quenches arcs while maintaining the voltage across the ionizer.  Charged particles are collected in a collecting section having a deflector electrode and a pair of collecting plates.  The deflector electrode includes a conductor embedded in a dielectric material having a dielectric constant greater than 1, which dielectric material suppresses arcs between the deflector electrode and the collecting plates.  The collecting plates are irrigated by a liquid flowing uni-formly and continuously from wash headers.  Each wash header includes a closed low pressure chamber having a plur-ality of large apertures disposed along the upper reach of its respective plate and a high pressure line disposed inside the low pressure chamber to discharge liquid into the chamber.  Baffles are provided to collect efficiently and with low pressure drop those charged submicron particles not collected on the collecting plates.

Abstract: ABSTRACT OF THE DISCLOSURE         A pipeline surge relief system including a relief valve of the type that opens when line pressure exceeds pressure in a pilot chamber.  A bleed valve, which is operable to evacuate the pilot chamber is opened when pipeline pressure acting against a diaphragm or piston overcomes an opposing reference signal or pressure.  The reference pressure is normally maintained at the pipeline pressure by a pressure differential valve which opens to a source of fluid pressure when reference pressure falls below line pressure.   However, the differential valve has limited flow capacity so that, in the event of a surge, flow of the reference pressure fluid lags behind the pipeline fluid, whereby reference pressure does not build up as rapidly at bleed valve and is over-come by pipeline pressure to open the bleed valve.

Abstract: CIRCUMFERENTIAL REGISTRATION CONTROL SYSTEM Abstract of the Disclosure A system for controlling registration in a Printing press between the moving web having repetitive print patterns and a work station operated cyclically in synchronization with the press.  The system includes a photoelectric scanner having a variable sensitivity, a position pulse generator with a backup accumulating device, a motorized compensator for controlling the longitudinal position of the web relative to the work station and a digital control circuit for driving the compensator to correct misregistration.  The control system counts position pulses during each cycle of the work station, defines a monitoring period during which marks and repetitive print patterns are scanned and signals differences between the cycles of the print markings and the work station by sampling at the occurrence of each mark, a digital number which cor-responds to the instantaneous position of the work station and its cycle.  To enhance selectivity the system employs a variable sensitivity scanner, a variable duration window or monitoring period and automatic setup apparatus that synchronizes the system to those portions of the web which are most distinctive and uncluttered.  Many other features and options are described.
