Abstract: ABSTRACT OF THE DISCLOSURE         A heat exchanger having a disc and doughnut baffle configuration, in which the tubes are laid out in a set of concentric rings.  Each ring of a set contains the same num-ber of tubes as each other ring of the set, and the tubes in each ring are spaced uniformly apart.  Each tube in each ring is located circumferentially midway between the two adjacent tubes of each neighbouring ring and is separated from each of the two adjacent tubes in each adjacent ring by a ligament distance h.  The distance h is held constant for all tubes in the set, by varying the radial spacing between rings, and the distance between any two adjacent tubes in any ring of the set is made greater than or equal to 2h.  The ligament gaps h which are constant therefore determine the minimum flow area between adjacent rings, and therefore the mass flow velocity through the tube bundle is constant.

Abstract: ABSTRACT OF THE DISCLOSURE A toy vehicle game includes an endless track defining at least two parallel vehicle lanes having vertical side walls in which two or more toy vehicles are adapted to be operated.   Each toy vehicle includes a reversible rotary drive motor and a transmission operatively engaged between the motor and one of two drive wheels for rotating one or the other of the drive wheels in the forward direction in response to the direction of rotation of the drive motor, thereby biasing the toy vehicle against one or the other of the side walls to guide the toy vehicle along its path of travel in one or the other of the two vehicle lanes.  The track includes substantially flush electrical contact strips which supply power to the drive motors through current collectors mounted thereon.  A control system permits the operators to separately and independently control current to the contact strips and also to selectively reverse the polarity of the current so that the operators can vary the speed of their associated toy vehicles and cause the toy vehicles to move from one lane to the other.  When the polarity of the current to one of the toy vehicles is reversed, a boost in available average electrical power is made available to that toy vehicle for a first limited duration maximum period. After using the boosted average power the selected toy vehicle must return to its original lane to be operated there at a normal power level for a minimum of a second limited fixed duration period before power boost is again available.  A balancing control equalizes the maximum per-formance of the two toy vehicles.

Abstract: TORQUE RESPONSIVE DISCONNECT FOR A V-BELT DRIVEN ELEMENT   Abstract of the Disclosure In the variable speed V-belt drive of a combine harvester threshing cylinder, the driven sheave is torque-responsive, responding automatically to adjust drive belt tension according to the torque being transmitted.  A linear hydraulic actuator, integral with the drive sheave, is used to adjust an axially movable sheave half with respect to a fixed sheave half so as to vary sheave effective diameter and hence driven speed.  At any given speed setting, oil is trapped in the hydraulic actuator and oil pressure varies according to separating force between the halves of the drive sheave which in turn depends upon belt tension.          A pressure switch, connected so as to sense the oil pressure, has a set point such that at a predetermined maximum (overload) belt tension, the switch is actuated so as to declutch or disconnect the drive sheave from its power source, thus protecting the threshing cylinder and drive components from damage.  The signal from the pressure switch may be used also, or alternatively to actuate an operator warning signal.

Abstract: TRANSMISSION AND REVERSE GEAR SYNCHRONIZING THEREFOR       Abstract of the Disclosure Reverse gear synchronizing for a transmission of the type commonly used on large off-road vehicles is accomplished without the use of a reverse gear synchronizing clutch.  The input shaft of the transmission carries a high and low gear separated by a high/low synchronizer clutch.  Also, carried on the input shaft is a reverse gear and conventional clutch.  A shift rod has a first shifting collar in shifting communication with the high/low synchronizer clutch and a second shifting collar in communication with the reverse clutch.  A cam containing travel channels is in linked communication with the shifting collars such that movement of the cam produces clutch movement to engage the high, low, or reverse gear.  The travel channels of the cam are so defined to enable relative movement between the high/low synchronizer and reverse clutch, whereby clashing between the reverse clutch and pin of the reverse gear is eliminated when the transmission gearing is changed from neutral to reverse.
