Title: Automatic engine oil change indicator system
Inventor: SCHWARTZ ELLEN S
IPC: G01N33/30
Filed: 1986-10-31
Granted: 1992-03-17
Abstract: AUTOMATIC ENGINE OIL CHANGE INDICATOR SYSTEM            Abstract of the Disclosure A number indicative of the number of engine revolutions corresponding to the useful life of the engine oil in a motor vehicle is stored in nonvolatile memory.  As the vehicle is operated, the number is periodically decremented by an amount determined in relation to a penalty factor and the number of engine revolutions which occur in the period.  The penalty factor is periodically updated and is determined in relation to the operating temperature of the engine oil, based on empirically determined data.  The stored number represents the remaining life of the engine oil and is continuously displayed for the information of the operator.  A warning lamp is lit to alert the operator to change the oil soon when the stored number is reduced to within 10% of the originally stored value.  When the oil is changed, a reset switch is actuated and the number is reset to its original value.

Abstract: (57) ABSTRACT           A reflectometric method of measurement for a 2-channel reflectometer, wherein in connection with the calibration, the standard sample is placed in the measuring channel (4), the dimming of the measuring channel is set to a random position and the light intensities detected both in the measuring channel and the reference channel (14) are adjusted into balance by adjusting the dimming of the reference channel by aid of the measuring diaphragm (17), and the measuring of the sample is carried out by setting the intensities into balance, likewise by aid of the measuring diaphragm of the reference channel.  The reflectance value of the sample under measurement is calculated from the reflectance value of the standard, by aid of the set value of the measuring diaphragm obtained in the measurement and on the basis of the set value of the measuring diaphragm obtained in the calibration measurement.

Title: Method and an apparatus for mixing gravel and bitumen
Inventor: WENTZEL JARLE
IPC: E01C19/10
Filed: 1986-11-28
Granted: 1991-03-19
Abstract: A B S T R A C T :      A method and an apparatus for mixing gravel materials and bitumen.  The gravel material is mixed with a bitumen emulsion by causing the gravel mate-rial to fall onto an inclined screen (12) separating coarse gravel particles (G) from fine gravel partic-les (g) in such a manner that the coarse gravel par-ticles and fine gravel particles follow different paths of free fall while spraying bitumen separately onto the two gravel flows which then are reunited via oppositely inclined baffles (20, 22).  Prefer-ably the reunited bituminuous gravel material is then sprayed with additional bitumen and then allowed to fall freely onto further baffles (26, 28).

Title: Method for the selection of a common memory of a multi-processor system composed of individual microprocessor systems with collision avoidance
Inventor: PFEIFFER KLAUS
IPC: G06F13/18
Filed: 1987-03-31
Granted: 1991-02-26
Abstract: ABSTRACT OF THE DISCLOSURE        In a multi-processor system in which a plurality of microprocessor systems are allocated to a common multi-processor bus in cyclical fashion in a sequence prescribed by priority characterizing numbers assigned to said systems, the priority allocation of bus access is overlaid by a further method that coordinates the access of a microprocessor system to a region storing a common data base in a common memory.  One of the microprocessor systems functions as the main processor system and is authorized to up-date the data base and all other microprocessor systems function as subsidiary processors which can read the data base information.  Before its access, every microprocessor system accessing the data base communicates a status signal to the other micro-processor systems, this preventing the main processor system from up-dating the data base while one of the subsidiary processor systems is already reading the data base information.

Title: Large diameter nose bar roll apparatus for veneer lathe with automatic knife gap adjustment during peeling
Inventor: BROWNING ROBERT A JR
IPC: F16D3/68

Granted: 1991-11-05
Abstract: LARGE DIAMETER NOSE BAR ROLL APPARATUS FOR     VENEER LATHE WITH AUTOMATIC KNIFE   GAP ADJUSTMENT DURING PEELING                 ABSTRACT OF DISCLOSURE          A large diameter nose bar roll apparatus for a veneer lathe is disclosed including an automatic knife gap adjustment means.  The knife gap adjustment means reduces the knife gap between the nose bar roll and the knife blade during peeling in response to decreases in the log diameter and/or changes in the knife pitch angle.  This knife gap adjustment maintains the nose bar roll in contact with the log at the proper contact pres-sure as the diameter of the log decreases during peel-ing.  This is necessary for nose bar rolls having a large diameter of at least 1.5 inches and 15 times the thickness of the veneer such as, for example, a nose bar roll of 3.75 inches diameter.  An electrical control means is employed for automatically controlling the knife gap adjustment means by moving the nose bar roll toward the knife in response to decreases in the log diameter and changes in the pitch angle.  The nose bar roll may be driven by power means to apply an auxiliary driving force for rotating the log in addition to the powered spindles provided at the opposite ends thereof for rotating such log during peeling.
