Abstract: ABSTRACT                A tension device for maintaining a predetermined amount of tensioning force on an endless drive belt for a vehicle accessories drive system.  A housing is mounted in a fixed position on the vehicle engine adjacent the drive belt. A lever is pivotally mounted on a shaft which is located within the housing and extends generally radially outwardly from the housing and is adapted to move in a belt tensioning direction.           A first pair of cylindrical, torsional coil springs is tele-scopically mounted on the shaft, with the springs being located one on each side of the lever.  A second pair of cylindrical, torsional coil springs is telescopically concentrically mounted on the shaft and surrounds the first spring pair.  One end of each spring is attached to the housing with the other spring ends being attached to the lever.  The spring pairs are placed in torsion and bias the lever in the belt tensioning direction. An idler pulley is mounted on the end of the lever and is moved into tensioning engagement with the drive belt by the torsion springs, or alternately one of the tensioning the drive belt which is engaged by the accessory pulley.  The tensioner construction enables a large tensioning force to be obtained from a rela-tively small, compact, simple spring arrangement by using three or more torsional springs.

Abstract: ABSTRACT        HOT AIR REWORK TOOL           A method and apparatus for directing a stream of hot air to localized areas of a printed circuit assembly until a temperature sufficient to melt solder is achieved, thereby facilitating the soldering/desoldering of circuit components mounted thereon.  The apparatus essentially com-prises a work station having upper and lower heat tubes through which a stream of turbulent hot air is directed, an adjustable support grid for supporting the pc assembly and a control means for controlling the temperature and flow of the air in the heat tubes.  The method being dependent on the use of a heat sensitive lacquer for detecting when the solder holding the component to the pc assembly has achieved a desired temperature and at which temperature the component can be removed or replaced.

Abstract: CONVEYOR CALIBRATION TECHNIQUE     ABSTRACT OF THE DISCLOSURE          A method is disclosed for calibrating a bulk mater-ial weighing and metering conveyor of the endless belt type providing a variable frequency signal indicative of feed rate.  In such a conveyor system, a belt speed signal and a tare-adjusted weight signal are multiplied to provide a product signal that is converted into a periodic pulse signal whose frequency indicates the feed rate (net weight per unit of time) of the material being metered by the conveyor.  In a first calibration step, the weight of the empty conveyor belt is measured over one belt revolution by counting the periods of the feed rate indicative pulse signal.  This count is then used to establish a tare weight reference value.  With the tare weight reference value established and the feed rate signal compensated therefor, a second calibration step is performed wherein the periods of the feed rate indicative pulse signal are again counted for a known increment of belt travel with a known net weight of material for such increment of belt.  This second count is compared to the theoretically expected count, such comparison being used to determine the accuracy of the indicated feed rate and to effect necessary calibration adjustments if needed.

Abstract: D-23,465 DISCHARGE LAMP WITH INTEGRAL STARTER                       ABSTRACT OF THE DISCLOSURE     A low wattage high intensity discharge lamp having a quartz arc tube and a glow starter disposed within a bulbous glass envelope containing an inert gas, such as argon, at subatmospheric pressure. The starter within the envelope comprises a first bimetal connected to one of the arc tube lead-in wires, a second bimetal connected to one end of a conductive support wire sealed through the bulbous envelope, and a fixed first contact attached to another conductive support wire sealed through the bulbous envelope and also connected to the other lead-in wire of the arc tube.  The bimetals are elec-trically connected together at one end which makes a normally closed contact with the fixed contact in the quiescent state of the starter.  Energization of the lamp causes short circuit current to flow through the starter to cause flexing of the second bimetal for separating the bimeta1s from the fixed contact to provide an open circuit thereat and produce a high voltage pulse switching transient across the arc tube electrodes.  Upon starting of a discharge in the arc tube, the lamp current flow through the starter is operative to maintain the bimetals separated from the fixed contact.  The ampli-tude of the pulse produced by the starter is controlled by the selection of the gas and pressure thereof within the bulbous envelope.

Abstract: BALLET TOE SHOE AND PROCESS    OF MANUFACTURE THEREOF          ABSTRACT OF THE DISCLOSURE           A ballet dancer's toe dancing ballet shoe is designed and manufactured more simply than conventional ballet toe shoes.  A sole supporting shank of the toe shoe has a tip flap at the front thereof which may be folded up to define the front panel of the completed ballet toe shoe. The shank is applied to a male mold member which is inserted into a female mold member cavity and resin is inserted into the space between the mold members for defining a toe box support frame in which the inserted portion of the shank and tip flap are embedded.  The shank is comprised of a leather-like material.  The completed combination of the shank and toe box support frame are removed from the mold members.  A ballet toe shoe upper is fastened to the shank and over the exterior and in the interior, as well, of the toe box sup-port frame.  The space between the mold members is greatest toward the interior of the cavity and gradually diminishes toward the exterior of the cavity, thickening and giving greater strength to the front of the toe shoe than to the rear portion of the toe box.  The shank and resin combina-tion eliminates intricate processes and skilled labor now required to manufacture toe shoes.  At the same time, the desired properties of varying degrees of stiffness of the shoe upper and of proper support for the dancer's foot are maintained.

Abstract: Abstract of the Disclosure In a wall construction comprising a pair of top plates, a bottom plate and plurality of parallel joists connected between the top and bottom plates, a wall brace is secured in a plurality of aligned saw kerfs to increase the load carrying capability of the wall structure.  The brace includes a substantially U-shaped base portion and a pair of side flanges extending normal to the base portion such that the brace is substantially T-shaped in cross section.  The brace is specifically designed so that the moment of inertia about the major axis (an axis aligned in the direction of the base) is greater than the moment of inertia about the minor axis (an axis aligned in the direction of the flanges).  The preferred construction of the wall structure assures that failure of the brace upon overloading of the wall structure is caused to occur within the plane of the wall.  In the preferred construction, the brace is secured to the wall structure by a pair of nails aligned in guide channels within the U-shaped portion of the base at each end of the brace so that the nails extend through the centroid of the brace and reduce torsional moments which tend to urge the brace out of the saw kerfs when a load is applied to the wall structure.
