Abstract: ABSTRACT OF THE DISCLOSURE           A tubular heat-exchanger unit is provided herein.  The heat-exchanger unit includes a plurality of heat exchanger tubes placed in u stacked, spaced-apart relationship and disposed substantially parallel to each other in both the vertical and the orizontal directions, each of the opposing end portions of the plurality of tubes being adheringly embedded in a wall of a hardened, elastic material, disposed transverse to the longi-tudinal direction of the tubes, the wall at both end portions of the tubes sealably separating an inner zone defined by the space around the tubes from the end zones, which end zones communicate with the space within the tubes.  Metal profile bars are sealably adhered to the wall of the elastic material at the uppermost and the lowermost sides of the stack and at both opposing end portions of the tubes, the plurality of stacked tubes being disposed on n base plate.  The base place contains a plurality of spacer elements which extend substantially vertically from the base plate for providing horizontal separation between adjacent rows of heat-exchanger tubes and also contains additional spacer elements disposed transverse to the longitudinal direction of the heat-exchanger tubes for providing vertical separation between adjacent rows of heat-exchanger tubes.  The tubular heat-exchanger is adapted to handle a first medium through the tubes themselves via the end zones, and a second medium which flows around the tubes, trans-verse to the tubes through the inner zone.  This provides a heat-exchanger unit in which the heat-exchanger tubes, being elastically sealed together, provide a tight elastic seal for the tubes.  A novel method for manufacturing the heat-exchanger unit is also provided.

Abstract: ABSTRACT OF THE DISCLOSURE       Fuel control apparatus for dual chamber stratified charge engine systems utilizes a single point fuel control arrangement for the main (lean) air-fuel mixture in combination with a multi-point fuel injection arrangement for the igniting (rich) mixture.  The single point and multi-point arrangements may be essentially independent in that they both sense and compute quantity of air flow, respectively, and meter and inject fuel respectively.          In an alternate form of the invention, the air flow sensing function of the single point arrangement is used to provide suitable air flow information to the multi-point arrangement and in another alternate form of the invention the fuel flow injection function of the multi-point arrangement is used to provide suitable fuel flow information to the single point arrangement.  The alternate forms of the invention reduce the overall complexity of the combined system by interrelating the single point and multi-point arrangements, thereby eliminating component and functional duplicity.

Abstract: ENDLESS CONVEYOR                   ABSTRACT OF THE DISCLOSURE    An endless conveyor and belt where the conveyor belt is made from a plurality of laterally extending rods linked together at the edges of the belt to form a fixed pitch driv-ing chain on one edge of the belt and a variable pitch chain on the other edge of the belt.  The driving chain is formed of links extending upstream from rods and surrounding the adjacent upstream rods.  The links in the variable pitch chain loosely surround the adjacent rod ends to permit relative movement between the adjacent rods.  The rods rest on fixed supports which, during movement of the belt along the path of the conveyor, exert drag forces on the rods tending to rotate the upstream-extending links of the fixed pitch chain against seats on adjacent upstream links, thereby locking the links one to another and supporting the rods against drag forces with-out column loading.  Drive forces are not transmitted across the belt.  The ends of the rods at the variable pitch chain float with respect to each other.

Abstract: Title of the Invention ACTUATOR FOR A WIRE MATRIX PRINTER AND METHOD OF MAKING          Abstract of the Disclosure An actuator for a wire matrix printer including a plunger having opposed abutment areas thereon, which plunger is mounted in a frame for reciprocal movement between first and second positions therein, and the plunger has a print wire fixed thereto by a special swaging technique.  The plunger is moved to and held in the first position against the bias of a special "H"-shaped spring (having opposed fin-gers to engage the abutment areas on the plunger) by a permanent magnet.  When the actuator is to be fired, a neu-tralizing coil is energized to nullify the holding effect of the magnet, enabling the spring to accelerate the plunger towards the second position (towards a platen).  The spring is disconnected from the plunger after it is accelerated, enabling the plunger and print wire attached thereto to travel ballistically at least part of the way to the second posi-tion from the first position.

Abstract: Abstract A thermally operated actuator useful as a relay, flasher, circuit breaker, or the like, in which a bimetal element is movable by heating and cooling in response to an electrical resistance heater and/or current passing through the bimetal element.  In one form of the invention ambient compensation is achieved by rigidly clamping one end of the bimetal element to provide a cantilever support, and providing a support at the other end that either clamps or pivotally engages the bimetal element and longitudinally compresses the element, causing the element to buckle into a curved configura-tion.  Heat is applied selectively to the bimetal element adjacent either end to produce a snap action change in the shape of the element between two fixed positions.  In an alternative form of the invention, two parallel bimetal elements are linked together to provide ambient compensation while still providing the snap action change in shape in response to selectively applied heat.

Abstract: ABSTRACT OF THE DISCLOSURE A hydrodynamic shaft seal is provided having a single annular shaft engaging washer clamped within a metal case.  The washer, prior to assembly on the shaft, has an inner wall which is perpendicular to the flat walls thereof but spaced from the longitudinal axis of the washer by a distance which increases and decreases in a cyclic radially undulating fashion. Thus, the inner diameter of the unstressed annular member is scalloped and includes from one to approximately sixteen periodic scallops, the number of such scallops preferably increasing as the diameter of the seal increases.  Such a seal is particularly easy to make and the varying angle of contact of the seal with the shaft occasioned by the scallops provides excellent hydrodynamic pumping as is desirable in such seals.
