Abstract: ??           VARIABLE PULLEY TRANSMISSION            Abstract:          A power transmission (20, 42, 54, 46) adapted to be connected between a prime mover (40) and a driven means (48, 48) which comprises a variable pulley drive (20) comprising drive and driven pulleys (22, 24) connected by a belt (30), each having at least one flange (34, 36) axially movable with respect to the other.  The pulleys continuously rotate when the prime mover is operational. The output of the prime mover is directly connected to the pulley drive.  The prime mover may be an automobile engine, the driven means may include the wheels of an automobile. A speed-responsive friction starting device (42) with means (44) to shift between neutral, forward and reverse is connected between the driven pulley and the driven means. Shifting of a dry, i.e., non-lubricated, belt on the pulleys when the speed ratio is changing is enhanced because of the continuous driving of the pulleys.  Also, because the direction of the rotation of the pulleys is always the same, shifting between forward and reverse is enhanced, this being true for any type of belt.  The drive ratio between the pulleys is controlled by a hydraulic control arrangement (52) which is both engine speed and torque responsive and the drive to the vehicle wheels may be through a synchronizer (35) or a planetary gear arrange-ment (352) to a differential (46).

Abstract: Abstract of the Disclosure A process for producing a gasified solid product comprising an undissolved gas in a matrix of solid material comprising a fusible sugar.  In the process, an aqueous solution of fusible sugar is continuously fed to an evaporator.  The solution is continuously heated while it is flowed through the evaporator to drive off water and produce a concen-trated fused sugar composition whose moisture content is low enough so that, at room temperature, the compo-sition will congeal to a glass having a viscosity high enough to contain pressurized gas bubbles therein. The concentrated fused sugar composition is contin-uously discharged from the evaporator and a gas at a pressure of at least about 400 psig is introduced into a stream of the concentrated fused sugar composition The concentrated fused sugar composition and gas are flowed through an in-line mixer and there subjected to intense agitation sufficient to achieve uniform dis-persion of the gas throughout the sugar composition, thus producing a gasified fused sugar composition. containing small evenly distributed bubbles of undis-solved gas at a concentration of at least about 3 ml (STP) gas per gram of concentrated sugar composition The gasified fused sugar composition is cooled to pro-duce a product comprising a solid matrix comprising sugar and having the properties of a glass and, con-tained within said matrix, evenly distributed small bubbles of the gas.

Abstract: CHAINSAW ACCESSORY                     ABSTRACT OF THE DISCLOSURE        An accessory device is provided for securement to a conventional portable type chainsaw to define a fixed predetermined distance of the cutting plane of the saw from an end of a work to be cut.  With this arrangement, successive cuts of identical lengths can be rapidly made.  The accessory itself comprises a plurality of straight cylindrical tubes nested in telescoping relationship and with appropriate frictional engagement with each other.  With this arrangement any desired length can be defined by the extent of telescoping of the tubes and the defined lengths remain fixed as a consequence of the friction between the tubes.  This fixed length can thus be used for successively measuring off equal cuts of a log or other wood to be cut by the chainsaw and the operator need not be concerned with further adjustments until such time as the successive cuts are to be changed in length.

Abstract: Electronic Fuel Control System Abstract Fuel flow to a gas turbine engine is controlled in response to power lever position and CDP by a hydromechanical section.  The hydromechanical section includes a torque motor which may be activated to modify the fuel flow to the engine in response to a control signal  produced by an electronic control section.  The electronic control section senses a number of engine and ambient parameters and generates engine operating limits from these parameters.  The limit corresponding to the lowest maximum engine speed is selected and referenced to actual engine speed for generating the control signal, thereby providing a closed loop engine speed control.  At least one of the computed limits is an actual maximum engine speed for steady state engine operation and is used to recompute the engine scheduled speed so that the actual maximum engine speed is obtained at the maximum power lever advance position; in this way power lever dead band is eliminated.  The electronic control also modifies fuel flow to the engine for speed synchronization with another identically con-trolled engine.

Abstract: ABSTRACT OF THE DISCLOSURE     A regenerator associated with a heat carrier roller, whose casing is flowed through twice by the media currents held separated by the partition in the rotor interior.  The regenerator has high specific heat exchanger output by which the installation area of such regenerators can be substantially expanded.  A regenerator according to the invention is adapt-able to the requirements of the respective insertion cases.       Thus, for example, the length of the heat exchanger roller can be chosen corresponding to the depth of the plant canals, which naturally facilitates the installation in plants with the typical rectangular canals of low height and great depth.          Independent of the chosen length, a most extensively even temperature distribution is attained in the heated media current and, in any event, no hazards then confront the in-stallation in the high temperature range when temperature-sensitive components, such as roller bearing and rotation drive, are arranged removed from the flowed through areas.          In view of the diagonally flowed through heat exchanger roller, it is possible, in a simple manner, to position bearing and drive, easy to maintain and cooled outside in the flow ducts.  By similar or different formation of the areas separated by the partition in the rotor interior, an extensive adaptability to each of the required media conductions and heat exchanger requirements is possible.
