Title: Engine-transmission control system
Inventor: ROSS WILLIAM A
IPC: F16H61/46
Filed: 1979-07-06
Granted: 1982-01-19
Abstract: Abstract An engine-transmission control system having an engine associated with a variable hydrostatic transmission with a ratio governor valve to set the transmission ratio and, thus, control engine speed, a horsepower demand signal valve and an engine speed signal valve with the signals derived from these valves being applied in opposition to the ratio governor valve for control thereof, and an engine fuel governor for the engine providing an operating curve for the engine which relates engine speed to engine horsepower to cause operation along the locus of minimum fuel consumption for the engine whereby operation of the transmission to set the engine speed determines engine horsepower by operation of the engine along the operating curve.  The system includes first linkage means associating an accelerator pedal with the horsepower demand signal valve and the fuel governor to provide a range of movement for the horsepower demand signal valve greater than that of the fuel governor.  A lost motion connection in the linkage means permits operation of the fuel governor in advance of the horsepower demand signal valve upon initial movement of the accelerator member.  Second linkage means associated with an engine brake member enables control of the horsepower demand signal valve without movement of the fuel governor and is interrelated with the first linkage means whereby one linkage means may operate independently of the other.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides a device for locking a weapon support, rotatable on a horizontal axis of rotation, of an elevationally trainable weapon, relative to a member supporting it on the outside of a turret of a vehicle, which turret   is capable of swivelling about a vertical axis of rotation, said device comprising a bore and a bolt on a free end of which there is a handle which can be turned through 180°, said bolt being capable under spring pressure of moving axially in a helical track in a casing surrounding the bolt, the bore being disposed  in the weapon support and the bolt casing being located in the turret hood and extends into its interior, the helical track being contained in a gate which, between limit latching positions for latching, and for unlatching, has an intermediate latching position for the bolt enabling it during the swivel of the weapon support to run onto run-on faces which flank the bore in the weapon support in the engagement area of the bolt with the axial movement of the bolt generated by the run-on  faces   overcoming the pressure of the spring and causing an index pin rigidly connected to the bolt to be force-controlled by the gate into the latching position.

Abstract: L.P.C.(HO) 6072 GLASS-CERAMIC DENTAL RESTORATIONS    Abstract of the Disclosure A glass-ceramic containing Li2O, CaO, A12O3, SiO2, platinum and Nb2O5 is disclosed.  It is highly suitable for use in dental restorations because of its combination of castability, chemical durability and mechanical strength. The aesthetic qualities of natural teeth may be reproduced by proper control of processing parameters, e.g. addition of coloring additives and devitrification heat treatment schedule.  Dental restorations may be made by casting a melt in a conventional dental laboratory investment mold, followed by devitrification.  Fracture of cast margins is avoided because of the mechanical strength and toughness of the glass-ceramic.  Partial restorations can be bonded with dental cement directly to the tooth of a recipient without the need for building the restoration upon an undercoat of metal alloy.

Abstract: ABSTRACT A method for extending the range of operation of an electromagnetic  fuel  injector  for  an  internal  combustion engine employs a technique for reducing the time required for the  injector  to  open  while  at  the  same  time allowing  the injector  to  maintain  a  minimum  closing  time.   Prior  art techniques  have  utilized  a  regulated  voltage  supply  to determine the precise voltage applied to the inductive element of the injector to cause it to open.  The present invention does  not  regulate  the  applied  voltage,  but  instead  the invention allows  an  unregulated  battery or  other DC supply voltage to be applied to the inductive element to cause the injector to open as rapidly as possible. The current in the injector is sensed to allow a reduction in the applied voltage when a predetermined maximum current occurs in the inductive element.  The voltage reduction permits a holding current to be  established  in  the  inductive  element  to  maintain  the injector open.  The holding current is low to reduce the time required to close the injector.

Abstract: ABSTRACT OF THE DISCLOSURE                 COOLING APPARATUS AND METHOD IN A               LIQUID CRYOGEN TREATMENT PROCESS      Compressors are utilized in an apparatus for treating a product such as tobacco with a liquid cryogen, such as carbon dioxide for removing vapor from a processing chamber and re-compressing the vapor to facilitate its return to the cryogen system.  When the compressors do not receive a supply of cool vapor from the processing chamber, the compressor temperature rises and the pressure drops.  When the pressure reaches a predetermined minimum setpoint, the compressors are inter-connected by means of a remotely controlled valve to a vessel containing cryogen vapor at a pressure greater than the pressure at the compressors.  A supply of cool cryogen vapor thus flows to the compressors to reduce the temperature, thereby allowing continuous operation of the compressors during periods in which cryogen vapor flow from the processing chamber is interrupted or delayed.

Abstract: ABSTRACT OF THE DISCLOSURE     An explosive powder operated setting device uses the propellant gases from an ignited explosive powder charge for driving a piston which, in turn, propels  a fastening element from the device into a receiving material.  The device includes a housing, a barrel mounted in the housing with the piston displaceably mounted in the barrel.  A tubular-shaped slide valve is rotatably mounted in the rear portion of the barrel behind the piston.  The front end of the slide valve combines with the barrel in forming a space in which the propellant gases contact the piston and drive it through the barrel.  The rear end of the slide valve forms a part of the combustion chamber within the device.  At its front end, the slide valve is frusto-conically shaped and forms a seal with a correspondingly shaped surface in the barrel.  An exhaust duct section extends through the barrel and is in communication with another exhaust duct section in the housing.  The slide valve has exhaust openings extending radially through it which can be aligned with the exhaust duct section in the barrel so that, if required, a part of the propellant gases can be exhausted to the atmosphere without being used for driving the piston.
