Abstract: SYNCHRONIZED TRANSMISSION Abstract of the Disclosure A tractor transmission is synchronized between four dif-ferent speeds in each of two different high and low ranges and a reverse range using an effective and relatively compact arrange-ment of elements.  A top shaft coupled to be driven by the tractor engine has four different gears concentrically and ro-tatably spaced along the length thereof with each of the four gears being in constant mesh with a different one of a second group of four gears formed on the outer surface of a counter shaft.  The counter shaft which is journaled for rotation about a differential drive shaft is selectively coupled to the top shaft by either of two pairs of synchronizers concentrically mounted on the top shaft between different pairs of the first four gears and operative to engage one of the first four gears to the top shaft in synchronized fashion.  High and low ranges of four different speeds are respectively provided by a first splined collar capable of coupling the counter shaft directly to the differential drive shaft and a second splined collar capable of coupling the differential drive shaft to a low range driven gear which meshes with a portion of the fourth gear disposed about the top shaft.    The top shaft is optionally coupled to the tractor engine via a planetary gear arrangement which utilizes a pair of clutches coupled between a rotatable carrier with included planetary gear arrangement to couple the carrier to a stationary housing or to the top shaft via an arrangement of sun gears to provide either underdrive or direct drive.  Upon loss of hydraulic fluid pressure required to bias the clutches into the direct drive condition, the planetary gear arrangement is automatically returned to the underdrive condition by mechanical springs within the two clutches.          Similar safety features are provided in connection with the front wheel drive portion of the transmission by use of a clutch biased by mechanical springs into the desired condition in the event of loss of hydraulic fluid pressure.

Abstract: ABSTRACT      A device to prevent undesirable paying out under excess loading of a strop forming part of a load restraining means (including vehicle seat belts or safey harness) comprises a housing for receiving an intermediate part of a strop and including a roller around which the strop is guided.   The roller is mounted so that it becomes dislodged when tension in the strop exceeds a predetermined value and the strop becomes trapped between the roller and a part of the guidance means which is curved in the opposite sense to the roller in order to produce a gradual stress gradient in the strop to reduce risk of parting. The roller is supported on bushes engaging chamfered apertures in flat washers and which will disengage under excessive resultant force on the roller.   Slots cut into the ends of the rollers define teeth which serve to support the roller on cam members formed integrally with the housing with lobes which enter the slots on roller displacement.

Abstract: ABSTRACT           An automatic, cam-actuated precision transfer apparatus operable to transfer and simultaneously invert workpieces between adjacent work stations.  The transfer apparatus utilizes a common input shaft to provide input rotation to both a stationary oscillator device as well as an indexer device rotatably mounted atop the oscillator. The output of the oscillator device horizontally oscillates the rotatable indexer device through a desired number of degrees of rotation, and the indexer's output vertically indexes a turret-type transfer arm assembly which has associated pick and place units.  The combined indexing and oscillating movements produced by the transfer apparatus allow a workpiece to be picked up at a first work station, vertically inverted while being horizontally transferred, and finally deposited at a second work station.  The trans-fer apparatus is adjustable to accommodate any variations in manufacturing setups.

Abstract: A B S T R A C T     "APPARATUS FOR MEASURING THE EFFICIENCY OF            COMBUSTION APPLIANCES" This disclosure relates to apparatus of the kind suitable for taking spot measurements of the heat loss or stack loss and/or efficiency (?) in flue gases (stack loss) and comprises respective sensors (5, 3) for producing output signals which vary with the temp-erature and the concentration of a constituent gas e.g. O2 of the flue gases and microprocessor-based computation means (10) arranged to derive measurement values of (and numerically equal to)  the measured temperature and constituent gas concentration, from the two sensors and to apply these measurement values in the computation of a predetermined formula relating the stack loss or efficiency to the measured quantities. In accordance with the invention, the apparatus is arranged to automatically calibrate the or each sensor from a test measurement prior to deriving the measurement values. This may be achieved in the case of a sensor having a non-linear response, by performing a calculation of a formula defining the non-linear response of the sensor using a coefficient derived from the test measurement. The sensor is thus automatically calibrated and "linearised" from a single test measurement. The predetermined stack loss or efficiency formula may be modified for different types of fuel, and temperature and O2  (or CO2) values used in the calculation as well as the result of the calculation may be presented on a visual display (24). The apparatus requires a minimum of operator expertise and reduces the possibility of human error associated with known stack loss measurement apparatus of the kind in which the operator is required to refer to charts to determine the stack loss from separate temperature and oxygen concentration readings.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for detecting oil mist or other light-affecting contamination in a fluid comprises a measuring chamber across which a light source directs a beam of light on to a photocell. Solenoid valves each control the connection of a respective inlet pipe (connected, for example, to a particular part of an internal combustion engine being monitored for oil mist) to the measuring chamber.  The solenoid valves are operated in sequence so as to admit respective samples of the atmosphere into the measuring chamber where the degree of contamination is detected by the changing photocell output. The samples are drawn into the measuring chamber by suction from a fan unit. The fan unit is also connected by a by-pass chamber and by-pass pipes in the individual valve units to the inlet pipes on the upstream sides of the valves.  In this way, the inlet pipes are kept charged with atmosphere from the areas being monitored so that each sample is very rapidly sucked into the measuring chamber when a valve is opened.

Abstract: HIGH VOLTAGE SEMICONDUCTOR DEVICE HAVING              AN IMPROVED dv/dt CAPABILITY Abstract of the Disclosure A semiconductor device used for high voltage applications exhibits reduced susceptibility to being inadvertently turned-on by capacitive charging currents generated by relatively high voltage transients impressed across an anode and a cathode of the device.  The capacitive charging. currents are manifested as a gate current which in a thyristor renders the device conductive if it exceeds a critical value and in a transistor is multiplied by the current gain.  A conductive ring and adjacent groove are employed on the surface of the device, along with certain interconnections, to maintain the level of the transient-produced gate current at a value below the critical value.

Abstract: Abstract of the Disclosure Disclosed is a data processing system in which a unit needing to be serviced by a processor first requests an interrupt and, after the interrupt is granted by the processor, requests access to a system bus to transfer interrupt information as it normally would transfer other information.  The interrupting unit must wait for other units having higher priority to transfer information, usually memory information over the bus, before it can access the bus to transfer its interrupting information.  This permits transfers of information having high-er priority to occur before the transfer of the interrupt information is trans-ferred.

Abstract: Abstract of the Disclosure A restraint system for a vehicle bunkers-combined with a privacy and light-excluding curtain to provide a system which is easily engaged and disengaged from the inside of the bunk.  The bottom edge of the upwardly openable center curtain panel is closed only with secure-ment of the bottom ends of restraint strips, so that the restraint system is used whenever the curtain is fully closed.  The lower ends of the restraint straps are simply slipped through loops at the inside surface of the curtain panel, just above the latching devices at the ends of the restraint straps, so that connection of the restraint to the curtain is easily and efficiently accom-plished, and separation of the two is easily made when desired.  Depending storage straps are provided for storing the curtain, with or without the restraint straps, in raised, rolled-up condition.  The entire curtain and restraint system, including side panels, is removably secureable to the sleeper bunk by means of quickly fas-tenable pin and hole structure and hook and looped fabric type fasteners.  The system makes use of the restraint straps convenient and nearly mandatory whenever the curtain is to be closed, yet enables the restraint portion of the system to be used independently of the curtain, with the openable curtain panel in the stored position.

Abstract: ABSTRACT OF THE DISCLOSURE         A high power MOSFET has a plurality of closely packed polygonal sources spaced from one another on one surface of a semiconductor body.  An elongated gate electrode is exposed in the spacing between the poly-gonal sources and cooperates with two channels, one for each adjacent source electrode J to control con-duction from the source electrode through the channel and then to drain electrode on the opposite surface of the semiconductor body.  The conductive region adjacent the channel and between adjacent sources is relatively highly conductive in the section of the channel adjacent to the surface containing the sources.  The polygonal shaped source members are preferably hexagonal so that the distances between adjacent sources is relatively constant throughout the device.  Each polygonal region has a relatively deep central portion and a shallow outer shelf portion.  The shelf portion generally underlies an annular source region.  The deep central portion underlies an aluminum conductive electrode and is sufficiently deep that it will not be fully penetrated by aluminum spiking.
