Abstract: METHOD OF PRODUCING MULTIPLE COIL, MULTIPLE TUBE HEAT EXCHANGER             Abstract of the Disclosure A heat exchanger is produced from a plurality of cylindrical coils, each formed from multiple tubing of essentially circular cross section and through which different liquids are to be passed, with the usual number of tubes being two.  A mastic layer is provided in the interstices between the turns of the tubes forming adjacent cylindrical coils, and also on the inside and outside of the turns of the inner and outer coils.  Preferably, the turns of each coil are generally in contact with the adjacent turns of the same coil and also with the turns of the adjacent coil, both beneath and above.  A principal feature of this invention is the placement of a mastic layer on the outside of each coil, after winding, and winding the turns of the next coil against the preceding coil, so as to squeeze the mastic layer into the interstices between the coil turns.

Abstract: TITLE          Motorcycle Apparatus ABSTRACT OF THE DISCLOSURE         Motorcycle apparatus is disclosed, in its preferred form, as a device for filtering and cooling oil including a novel and unique concealed mounting.  The oil filtering and cooling device includes a casing having internal and external heat dissipating members for receiving and transferring heat from the oil, through the casing, to the outside ambient air or atmosphere.  The internal heat dissipating members are shown in the preferred embodiment as including fins and shoulders which define an oil filter capturing cavity.          An oil filter is biased inside the cavity by a spring which allows the oil to bypass the filter when the filter becomes clogged.  The concealed mounting of the apparatus is accomplished by utilizing a mounting plate securable within an indentation formed in the back of the apparatus.  Specifically, the mounting plate holds bolts outstanding from the apparatus through apertures in the mounting plate by capturing the heads of the bolts in apertures formed within the indentation of the apparatus.  The bolts are securable to the motorcycle frame and especially to Harley-Davidson stock FX or XL frames.

Abstract: ABSTRACT OF THE DISCLOSURE A fine ozone corrosion resistant fuse wire is supported between conductive terminals which are, in turn, supported on and spaced apart by rigid insulator spacing means so that the fuse wire is extended.  Insulator shield means is placed over the fuse wire over a substantial length of the insulator spacing means to shield the insulator spacing means from vaporized filament material to ensure that in all possible fuse failure modes that the circuit is completely broken but including a portion is unshielded so that vaporized material will plate on to the insulator to permit quick detection of a failed fuse.  The rigid insulator spacing means may take the form of a rod generally parallel to the fuse with the terminals as end caps fitting over the rod or it may take the form of a tubular member fitting around portions of the terminals and confining the fuse internally, preferably so that oxygen cannot readily reach the fuse when it is used in a concentrated oxygen atmosphere.

Abstract: ABSTRACT             A lid latch assembly (10) for a household washing machine is disclosed which incorporates safety features which prevent damage to the latch assembly regardless of when the drum access lid of the machine is closed.  The assembly includes a solenoid (22) operated locking lever (60) pivotally mounted to a bracket (12). An elongated slot (68) in the bracket defines a first fulcrum (66) about which the locking lever pivots during latching movement.  A switch arm (30) must be depressed downwardly by a latching hook (84) connected to the machine lid (80) before the locking lever is movable to the latched position.  A blocking tab (58) on the switch arm prevents movement of the lever to the latched position prior to downward movement of the switch arm.  The elongated slot allows the locking lever to pivot about a second fulcrum defined by the blocking tab.

Abstract: YARN TUBE WITH PICKUP GROOVE ACCOMMODATING      LEFT HAND AND RIGHT HAND PICKUP     ABSTRACT OF THE DISCLOSURE     In a yarn tube having a yarn-supporting surface, a yarn-receiving pickup groove formed in the surface and extending circumferentially at least partially around the tube.  The groove, specifically configured to accommodate both right hand and left hand yarn pickup, includes an elongated wide center section to allow proper dropping in and orientation of the yarn from both the right and left.          Extending outwardly from both ends of the wide center section are elongated narrow gripping sections which insure a proper snagging of the yarn, initially received within the wide section, regardless of the direction of rotation of the tube.  The wide section is of a constant width as are the narrow sections.  The entire groove is of a constant depth with the groove in the wide section being of a greater width throughout the height thereof than the width of the groove at the corresponding height in the narrow sections.

Abstract: Abstract The apparatus of the invention includes a planer, proximity type x-ray image intensifier (18) for detect-ing a fan beam of x-rays (8) and for producing an intensified output visible light image on an output display screen (26) which is sensed by a scannable, linear array of solid state diode detectors (38, 42,). In a-first embodiment, a pair of side by side arrays (38, 42) are utilized to eliminate the effects of flare in the display screen.  One of the linear arrays (38) looks at the line signal (32) on the output screen (26) and the second linear array (42) looks at a location on the output screen (26) which is adjacent and parallel to the line signal.  A net signal is derived by sub-tracting the signals from adjacent elements (Fig. 3) of the two parallel arrays (38, 42) so that signal flare in the image intensifier tube is removed.

Abstract: MONITORING SYSTEM AND METHOD UTILIZING SIGNAL INJECTION FOR DETERMINING CHANNEL      RECEPTION OF VIDEO RECEIVERS                        Abstract A system and method is provided for determining the channel to which a video wave receiver is tuned.  The system includes an RF signal source connected to the antenna input of the video wave receiver, a frequency control stage that determines the signal frequencies generated by the RF signal source and a system and advance control stage to appropriately program operation of the frequency control stage.  The RF signal source is conditioned by the system and advance control stage and the frequency control stage to output signals such that the fundamental or one of the harmonics when combined with the video carrier of a corresponding channel results in a signal having a predetermined frequency.  The RF signal source is successively advanced to output a set of predetermined frequencies, corresponding to each of the receivable channels to which the video receiver is tunable.  The system includes a detector/receiver arranged to monitor the video signal of the video receiver to detect the predetermined frequency resulting from the combined signal from the RF signal source and a video carrier to which the video receiver is tuned.  The RF signal source is stepped through a predetermined set of frequencies corresponding to each receivable channel and the system outputs a signal denoting the received channel to which the video receiver is tuned when the predetermined frequency is detected by the detector/receiver.
