IPC: C10M111/04
Filed: 1988-07-15
Abstract: Surfaces which have substantially continuous frictional contact, eg. reciprocating engine parts, are coated with a solid film lubricant having excellent wear characteristics and adhesion. The parts in question may be pistons, and the area to which the wear resistant solid lubricant film is bonded is the piston skirt -- i.e., all or a portion of the area below the piston rings. The lubricant is composed of a polyimide derived from 
2,2-bis[4-(4-amino- phenoxy)phenyl]hexafluoropropane ("4-BDAF") and an aromatic tetracarboxylic acid (or dianhydride or ester thereof) containing fluorinated carbon.

Abstract: A vortex flowmeter including a differential pressure transducer with high common mode rejection. No diaphragms are required. A relatively thick machined recess at one end of the vortex shedding body concentrates and transmits the vortex shedding differential pressure to strain transducers located outside the fluid flow conduit. Embodiments are disclosed in which piezoelectric elements and reflective optical fibers are used as strain transducers. The described arrangements allow the mechanical clamping of the transducers and their easy removal without a flow shut down. The shedder shape is optimized in relation to the differential transducer to strengthen the shed vortices and improve the linearity and repeatability of the meter.

Abstract: Disclosed is a method and apparatus for controlling a throttle valve (8) driven by a D.C. motor (3) in an internal combustion engine (1), in which the D.C. motor (3) is driven until a valve position sensor (4) detecting the angular position of the throttle valve generates an output signal which coincides with the output signal of an accelerator pedal sensor (6) detecting the amount of depression of an accelerator pedal of a vehicle. The value (i₁) of motor current required for causing very slight displacement of a return spring (12) provided for returning the throttle valve toward a pre­determined angular position is utilized for automatically compensating various factors of fluctuation attributable to friction, inertia, etc. of means (10, 12) driving the throttle valve. A small-capacity microprocessor is used to control the D.C. motor so that the throttle valve can operate with high accuracy and high-speed response capability without being adversely affected by changes in the operating condition as well as secular variations.

Abstract: An anti-skid brake control system monitors wheel deceleration during a period from a timing at which vehicular braking operation is initiated to a timing at which anti-skid brake control becomes active. Because the magnitude of wheel deceleration during the period set forth above is approximately inversely proportional to a road friction, the difference of deceleration can be a road friction indicative data. A vehicle body deceleration gradient data for the first skid control cycle is approximated or projected on the basis of the road friction indicative data so as to derive a projected vehicle body speed indicative data and a target wheel speed indicative data for the first skid control cycle.

Abstract: Devices fed with operating voltage and optionally additionally with additional voltage are monitored for the presence of the voltage(s) required in each case. Additional voltage is supplied via plug-in connection and causes the storage of the requirement for the additional voltage in a storage device fed with operating voltage, which can only be cleared by totally disconnecting the operating voltage, but not by detaching the plug-in connection. With storage of the requirement for the additional voltage, alarm signals are given due to a failure of the latter. <IMAGE>

Abstract: With a process for setting precious stones, especially brilliants, in precious metals or their alloys, the precious stone being surrounded at least in regions by the metal forming the setting, a solution is to be produced, with which precious stones, especially brilliants, can be set mechanically, the mechanical preparations being reducible to a minimum, as a result of which the setting process can be speeded up. This is achieved in that the precious stone is pressed under pressure into a borehole, the diameter of which is slightly smaller than the external diameter of the precious stone to be set, and in that, after the outer edge regions of the precious stone have been driven into the borehole below the level of the surface of the setting metal, metal material is rubbed from above over the outer edge regions of the stone to be set. <IMAGE>

Abstract: A low-level liquid scintillation measurement system for counting sample optical events resulting from the radioactive decay of a constituent of a sample to be measured while reducing the counting of background optical events which are optical events produced by background radiation and which create electrical pulses other than pulses representing a sample optical event. This system includes detection means (12,14,16,18) located adjacent the sample for detecting optical events and for converting optical events into electrical pulses, coincidence sensing means (24) for receiving the electrical pulses from the detection means (12,14,16,18) and producing a trigger pulse when the electrical pulses from the detection means (12,14,16,18) coincide with each other, burst detection means (30) for receiving the trigger pulses from the coincidence sensing means (20) and the electrical pulses from the detection means (12,14,16,18) for determining the number of electrical pulses present in a selected interval following each of the trigger pulses, evaluation means (32) connected to the burst detection means (30) for determining, in response to the number of pulses detected in the selected interval, the extent to which the optical event represented by the corresponding trigger pulse should be treated as a sample optical event or a background event, and an active guard shield arrangement (100) comprising an auxiliary scintillator (104) optically coupled to the detection means (12,14,16,18). The shield (100) is adapted to be excited by background radiation and to effectively increase the number of electrical pulses present in the selected interval following a trigger pulse generated as a result of the coincident pulses produced due to the background radiation. This allows the measurement system to accurately evaluate the number of pulses detected in the selected interval and determine the extent to which a trigger pulse is to be treated as a sample optical event.
