Patent EP-0096295-A3 (EP)
IPC: G11B19/28
Filed: 1983-05-25
Abstract: A drop-out detector for detecting the absence of a pulse 
in either of first and second pulse trains, especially for use 
with the spindle servo error generator of a videodisc 
mastering machine. Prior attempts at providing a drop-out 
detector function for the spindle servo error generator rely 
on the use of RC based timing circuits to create time 
windows within which to look for the presence or absence of 
a reference or tach pulse, as the case may be. Such 
arrangements provide satisfactory performance in connec­
tion with constant angular velocity type discs, since refer­
ence and tach frequencies remain constant throughout the 
mastering process. However, problems arise in utilizing such 
RC based circuits in connection with constant linear velocity 
type discs. The present invention overcomes these problems 
by operating on a pulse width modulation technique for 
controlling the spindle motor speed. In such an arrangement, 
rather than to phase compare two AC signals, one from the 
reference oscillator and one from the tachometer, a three-­
stage shift register is provided whose output is pulse width 
modulated by the difference in time relationship between 
two pulse train inputs, one pulse train representing a 
reference standard and the other representing the tacho­
meter output. A detector indicates when the states of the first 
and third stages of the shift register are the same which 
signifies an improper relationship between the tachometer 
pulses and reference pulses.

Title: Hitch control system
IPC: A01B63/111
Filed: 1984-06-04
Abstract: A hydraulic rockshaft actuator (24) operates a rockshaft (12) to raise and lower a hitch in accordance with mixed position control set by a lever (28) and draft control set by a lever (32). The set points established by these levers are combined mechanically with actual rockshaft position sensed mechanically by a ramp (14) on the rockshaft and actual draft load sensed hydraulically by a load sensor (34) and communicated to the mechanical combining arrangement (16) via a load control valve (17). In order to provide this known system with engine speed control (to avoid labouring the engine) and/or wheel slip control (to avoid excessive wheel slip), an electronic control unit (46) processes signals from corresponding transducers (54, 58, 60) and derives an electrical control signal. A pressure control valve (40) in the hydraulic line between the draft load sensor (34) and the load control valve (17) enhances the hydraulic load signal so that reduced engine speed and/or increased wheel slip emulates increased draft load and therefore leads to the hitch being raised. To this end the control valve (40) has electrical pilot control (44) responsive to the electrical control signal in parallel with hydraulic pilot control (42) responsive to the pressure from the draft load sensor (34). The draft control lever (32) sets the proportions of the mixed control and, within the control unit (46) the electrical control signal is gain-scaled in dependence upon a signal (A(6)) from a transducer (52) on the lever (32) so that the effect of the electrical control signal is the greater the greater the proportion of draft load control in the mixed control.

Abstract: A connecting rod design for minimizing friction and max­
imizing load bearing capacity of reciprocating crankpin 
assemblies, such as those found in internal combustion 
engines. Rather than the conventional journal bearing 
arrangement, the compressive load between wrist pin and 
journal center is borne by a hydrostatically supported pivoted 
pad slider arrangement which operates under mechanical 
conditions which superimpose pivoted pad slider and 
squeeze film fluid mechanics to maximize film stability and 
minimize friction. Inertial loads perpendicular to the wrist pin 
journal center line are borne by smaller hydrostatically sup­
ported pivoted pad sliders. Tensile loads are borne by a rela­
tively flexible rod cap bearing which deflects to maximize 
squeeze film forces.

IPC: C10G31/08
Filed: 1984-10-12
Abstract: The salt content of crude oil is reduced by washing crude 
oil containing residual salt water with wash water of lower 
salinity than the water present in the crude oil and allowing 
the resulting mixture to settle into a layer of crude oil of 
reduced salt water content and a layer of saline water. The 
quantity of wash water employed is greater than 7.5% by 
volume of the crude oil.  
     The saline water may be recycled and a proportion 
removed from the recycle stream and a corresponding quan­
tity of water of lower salinity added.  
     Washing with relatively large quantities of water results 
in the formation of a less stable emulsion. Consequently, less 
severe conditions are required to break it to recover the 
desalted crude oil.
