Patent EP-0324222-A3 (EP)
IPC: B24B5/00
Filed: 1988-09-26
Abstract: A workpart chuck (10) has a centreing (52) member that is 
movable toward the axis of rotation (R) of the chuck as the 
chuck rotates the workpart (W) in an eccentric non-centred 
position. As the centreing member moves the workpart, 
a sensing device (100) senses the extent of changing eccentric 
movement of the workpart and generates an electrical signal 
indicative of the extent of such eccentric movement. 
The workpart is moved toward the chuck axis (R) until the 
signal reaches a predetermined value indicative that the 
workpart is rotating about its axis; i.e. the workpart axis (G) 
and chuck axis (R) are substantially coaxial. The centreing 
member (52) is offset slightly relative to the chuck axis of 
rotation to ensure that excessive movement of the 
centreing member placing the workpart centre (G) beyond the 
chuck axis of rotation will not result in the workpart 
being driven to an extremely eccentric position and possibly 
even off the face of the chuck (10). The sensing device (100) detects 
a sudden shift of the workpart position relative to the 
centreing member (52) indicative of such movement beyond centre, 
whereupon the control system (110) causes the centreing member to 
retract a small distance and advance in a new attempt 
to centre the workpart.

Title: Analog electronic timepiece
IPC: G04C3/14
Filed: 1988-12-09
Abstract: An analog electronic timepiece comprises time 
keeping means (1, 2) for producing time of day 
information, a motor driving circuit (3,4) responsive to 
the time keeping means for generating motor driving 
waveforms, and a motor (5) responsive to the motor 
driving circuit. A time indicating hand (7) responsive 
to the motor (5) indicates time of day. An acoustic 
circuit (11, 13) is responsive to the time keeping means 
for emitting a sound at a predetermined time and 
includes a speaker (13). A control circuit (9) 
controls the motor driving circuit (3) so that the time 
indicating hand (7) is driven in a different way from 
when time of day is indicated in synchronism with sound 
emitted by the acoustic circuit. Moreover the control 
circuit (9) is responsive to the time keeping means for 
controlling the motor driving circuit so that the time 
indicating hand indicates the time of day after 
termination of the sound emitted by the acoustic 
circuit.

Title: Bicmos power transition circuit
IPC: H03K19/08
Filed: 1989-01-27
Abstract: A power transition circuit (2) protects a bipolar-­
CMOS (BiCMOS) circuit during power transitions. 
Reference signals (Vref+, Vref) proportional to the voltage supplied 
to the protected circuit (Vcc, Vee) are monitored, and the power 
transition circuit (2) determines from the voltage differen­
tial between the reference signals (Vref+, Vref) whether a power 
transition is occurring. If a transition is present, 
the transition circuit (2) disables the protected BiCMOS 
circuit for as long as the power transition exists. An 
independent input signal (Vcsm) allows the power transition 
circuit (2) to disable the protected BiCMOS circuit in 
response to other conditions.

Title: Comminution of material
IPC: B02C23/26
Filed: 1986-07-17
Abstract: Material is comminuted in a substantially dry state in a chamber (4) as a result of agitation by a rotor. During the process, gas is admitted to the chamber (4) through a foraminous base (8) to flow upwardly in a uniform manner across the cross-section of the chamber. Pulses of gas are directed periodically at the material through inlets (15) to prevent agglomeration of the material. The pressure of the gas admitted through the inlets (15) is higher than that admitted through the foraminous base (8). Surface active agents may be added to the material, also to prevent agglomeration, as well as, or instead of the use of pulsed gas.

Title: Data transfer method between memories
IPC: G06F3/06
Filed: 1989-08-29
Abstract: In a method for transferring data from a 
first memory (26) in a first terminal device (20) to a 
second memory (26) in a second terminal device (22) 
the first memory (26 in 20) is divided into a number 
of partitions (40-1 to 40-N). Stored in the first 
memory (26 in 20) are a plurality of data bits 
locating the begin and end blocks (42,44) of data 
space in each of the partitions (40-1 to 40-N). In 
the begin block (42) of each partition (40-1 to 40-N)

number of freespace maps (62) for its associated 
partition (40-1 to 40-N) together with the freespace 
maps (62) identifying the valid data that is to be 
transferred to the second memory (26 in 22). Using 
the information contained in the freespace maps (62), 
a processor transfers the data from the second memory 
(26 in 20) to the first memory (26 in 22).
Patent EP-0360476-A3 (EP)
Title: Homodyne-type spread spectrum transmitter/receiver
IPC: H04B1/707
Filed: 1989-09-12
Abstract: The present invention relates to a homodyne-type spread 
spectrum transmitter (10) and an associated remote spread spectrum 
receiver (30) which communicate with each other by the transmission of 
both (1) a spread spectrum Pseudo Noise Code (PNC) sequence signal, and 
(2) a combined PNC sequence plus the data information (PNC+data) signal. 
The two signals can be transmitted concurrently using either different 
frequency bands or on a quadrature carrier; or the two signals can be 
transmitted with a time offset between signals. At the receiver the PNC 
and the PN+data signals are separately recovered (33-35) for the case of the 
concurrent transmission techniques, and directly mixed (36) to despread the 
received signal and recover the data signal at baseband. For the time offset 
technique, the delay (41) provided in one of the time offset signals is again 
introduced to the previously delayed signal, and the delayed and undelayed 
signal portions of the received combined signal are directly mixed (36) and 
then low pass filtered (42) to recover the data signal. Such techniques 
eliminate the necessity for providing PNC acquisition and tracking circuits 
in associated spread spectrum transmitter and receiver combinations.
