Abstract: A high speed monolithic current switching digital-to-­
analog converter (DAC) is provided. The DAC includes input 
level shift clock and data drivers (401, 421), differential 
dual latches (403, 405), differential multiplexers (409) and 
high speed current switching cells (411). Utilizing comple­
mentary clocks at one-half the input data rate, data is 
effectively latched at each transition or edge of the clock 
pulse rather than at only the positive (or negative) going 
edge of the clock. Thus, feedthrough of the previously unused 
clock edge and perturbation in the DAC output caused by the 
unused clock edge is eliminated.

Filed: 1986-02-07
Abstract: A signal processing circuit for processing an input signal 
by first and second transmission circuits (11, 13) in positive 
and inverse time series respectively. The first and second 
transmission circuits have a same transfer function. The 
apparatus includes first and second memories (15, 16) and 
first and second switches (14, 17). The first and second 
memories are selectively connected via the first switch (14) 
to the first transmission circuit (11) output and via the second 
switch (17) to the second transmission circuit (13) input. Each 
memory repeats write and read operations alternately in 
such a manner that an output signal of the first transmission 
circuit (11) is written for a predetermined period and the 
written signal is read for the subsequent predetermined 
period in a time series inverse to that for writing and sent to 
the second transmission circuit (13). While one of the first 
and second memories (15, 16) is conducting write operation, 
the other is conducting read operation. The first and second 
switches and first and second memories are controlled by a 
control signal generated by a control circuit (18), which 
signal reverses its state with intervals of the predetermined 
period.

IPC: G01G9/00
Filed: 1986-06-17
Abstract: An apparatus for measuring the weight, thickness or com­
position of a coating or coatings applied to a substrate includes 
a primary radiation source (11), a detector means (10), and 
means (6) for processing radiation reflected by the coating or 
coatings. The source of primary radiation delivers an output 
which is applied to the coating or coatings and the detector 
means (10) receives the reflected secondary radiation, the 
detector means (10) including at least two energy-sensitive or 
energy-dependent detectors comprising ionisation chambers 
(12, 13) fitted with energy-sensitive radiation filters (14, 15) 
able to differentiate between different elements of the coating 
or coatings from one another, the outputs of the chambers 
(12, 13) being processed by the processing means to provide 
an indication of the weight or thickness of the or each coating 
irrespective of composition, or of the composition of the 
coating or coatings. The filters (14, 15) are preferably ab­
sorption-edge filters and the source of primary radiation (11) 
may be either an X-ray generator or a radio-isotope producing 
Gamma radiation. The absorption of the radiation filters (14, 
15) fitted to the ionisation chambers (12, 13) is selected so as 
to pass the reflected secondary radiation in accordance with 
the materials being subjected to the primary radiation from 
the source (11).
Patent EP-0225077-A3 (EP)
IPC: B24B49/16
Filed: 1986-11-10
Abstract: During grinding of successive workparts with a 
superabrasive wheel in a rough grind stage at a high wheel 
infeed rate and a finish grind stage at a relatively low 
infeed rate with spark-out stages after each of the rough 
and finish grind stages, the duration of the spark-out stage 
after rough grinding is made dependent on the condition of 
the grinding wheel and corresponds to the time needed for 
removing workpart material for the reduction of the grinding 
wheel motor power from the high rough grind level to the 
lower finish grind level. The duration of the spark-out 
stage will therefore be variable from one workpart to the 
next as the condition of the wheel changes. In addition, 
the interval of wheel retruing or dressing (i.e. number of 
workparts ground between wheel retruing) is variable as 
determined by the condition of the wheel. In particular, 
when the rough spark-out stage for a workpart is completed 
in a time shorter than a preselected minimum time indicative 
of a wheel that is in need of retruing. Typically, the 
occurrence of a drop in wheel motor power from the rough to 
the finish level during the preselected time interval is 
sensed and activates a memory circuit to store the fact that 
the machine needs to be placed in the wheel truing mode.

Title: Device for controlling polluting emissions from internal combustion engines
IPC: F02D41/06
Filed: 1986-09-12
Abstract: First (3) and second (9) inlet ducts are provided in the carburettor (C) of the engine and are located downstream and upstream respectively of the throttle valve (V) in the air intake direction. A first pneumatic line (2) puts the first inlet duct (3) into communication with the barometric control chamber (S) of an actuator (A) which controls the angle of ignition advance. The same barometric control chamber (S) is also put into communication with the second inlet duct (9) through a second pneumatic line (6) including at least one restricted section (l0) and a third pneumatic line (7). The first (2) and third (7) pneumatic lines have two associated solenoid on-off valves (4, ll), the operation of which is controlled by a sensor (l3) associated with the starter (W) and a heat sensor (l4) sensitive to the temperature of the engine lubricant. When the starter (W) is active, the low pressure downstream of the throttle valve (V) is transferred to the barometric control chamber (S) of the advance angle control actuator (A). When the starter (W) is returned to the rest position, the low pressure upstream of the throttle valve (V) is transferred to the barometric chamber (S) through the second pneumatic line (6) The restricted section (l0) of which delays the propagation of the pressure gradients towards the barometric control chamber (S) of the actuator (A). This operating condition exists until the temperature of the engine lubricant reaches a threshold level of the order of 45-85 DEG  C. When this treshold level is reached the third pneumatic line (7) is opened to put the second inlet duct (9) directly into communication with the barometric control chamber (S) of the actuator (A) for controlling the angle of advance and the ignition.

Abstract: A system for producing a digital representation of the value 
of an angle ϑ, typically a phase angle, from two analogue input 
quantities representative of A sin ϑ and A cos ϑ, where A is an 
amplitude factor, comprises logarithmic amplifiers (IC1-IC4) 
which produce analogue representations of a plurality of 
quantities (sin ϑ, cos ϑ, sin (ϑ+3π/4), cos (ϑ+3π/4)) derived 
from the two input quantities and which are arranged to add or 
substract their outputs to produce quantities (V₁-V₄) which are 
independent of A and the value of each of which lies within a 
predetermined range (-C to +C) in at least one respective portion 
(2π/n) of an angular range for ϑ of 2 π radians. The digital 
representation of ϑ is the concatenation of digital 
representations of the angular portion (2π/n) in which ϑ lies 
and of the value of ϑ within the portion that is derived from the 
selected appropriate one of the quantities V₁-V₄ with an analogue 
to digital converter. Such a system enables high resolution to 
be obtained at a high operating speed. Suitably, the quantities 
V₁-V₄ vary linearly with ϑ in their respective angular portions 
and are [log tan] functions of ϑ.
