Patent EP-0275195-A3 (EP)
IPC: H04R1/34
Filed: 1988-01-13
Abstract: Acoustic wave "diffractor" cavity arrays 
(1,2,8) are positioned obliquely in front of sound 
producting transducer(s) (3,4) to cause very wide 
angle dispersion of the sound waves projected from 
said transducer(s) (3,4) into said arrays. The 
arrays (1,2) may consist of a complex of bent and 
folded chambers. This system causes depolarization 
of the sound waves projected from the transducer(s) 
(3,4).

IPC: B22C9/18
Filed: 1988-02-08
Abstract: A sand core (66) is moulded between the top and bottom cores 
box sections (21 and 24) and, after the sections have been 
separated, the core stands above the lower section (24) on ejection 
fingers (70). A core removing device (44) is run into the space 
above the core (66) and carries fingers (60) which are lowered over 
the core to grip the same for removal of the core by reversal of the 
movements of the removing device (44). This device also carries 
beneath the fingers (60) a shaping plate (62) with a shaped 
aperture corresponding to the desired outline of the core. As 
the fingers (60) are lowered, the shaping plate is passed over the 
core and removes moulding flash (80) around its periphery.

Title: Optical sensor
IPC: G01N21/41
Filed: 1988-03-10
Abstract: A moire fringe displacement sensor includes first and second gratings (3) (4), a polychromatic light source (1) illuminating the gratings, and a detector (8). The gratings are disposed such that a relative displacement of the first and second gratings causes a variation in the colour of the light reaching the detector. The detector (8) comprises first and second photo-responsive elements (11) (12), the responsivity with respect to wavelength of the first element (11) being different from that of the second (12). Signals from the photo-responsive elements are fed to a micro-processor (15) which calculates the colour of the light incident on the detector as represented by two or more parameters on the Chromaticity (CIE) Diagram, and interprets the colour in terms of the displacement of the first and second gratings.
Patent EP-0297868-A3 (EP)
IPC: H01H13/50
Filed: 1988-06-30
Abstract: An electrical switch, e.g. a butterfly-type 
switch, includes a movable actuator (4) mounted 
in a housing (1) and biased by a compression spring. 
Two contact arms (6) pivotally engage notches (9) 
in the actuator (4) and are urged together by a 
tension sprint (8). A fulcrum (20) is provided 
for each contact arm so that during closing movement 
of the actuator (4) in the direction of the arrow 
the contact arms pivot about the fulcrum (20). 
When the horizontal position of the arms (6) is 
reached they pivot rapidly upwardly to interconnect 
fixed contacts (2). During the return movement 
the contact arms (6) pivot about the point of contact 
between contacts (2) and contacts (7). This arrange­
ment allows an increased contact gap in the open 
condition for the same amount of movement of the 
actuator (4).

Patent EP-0349993-A3 (EP)
Title: Slip control apparatus
IPC: F16H59/50
Filed: 1989-07-04
Abstract: A slip control apparatus is designed such that an 
output from the engine is rapidly reduced to a set limit 
value by means of feed-forward control when a friction 
coefficient on pavement gets large and the engine output 
reduced to the set limit value is then returned to a set 
return value larger than the set limit value by means of 
the feed-forward control. After returning to the set 
return value, the engine output is subjected to feed-back 
control so as to turn a slip value of the driven wheel to 
a target value. The set limit and return values can be 
changed in accordance with the friction coefficient on 
pavement and a vehicle speed. The set limit and return 
values can be corrected in a direction in which they 
become larger when the slip value gets larger on account 
of the upshifting of the transmission.

Patent EP-0385438-A3 (EP)
IPC: F16H59/46
Filed: 1990-02-28
Abstract: When a shift command is issued the line pressure is 
dropped to a first low level until such time as the inertia 
phase of the shift begins. From this time the level of 
line pressure is raised and maintained at a second higher 
level until the end of the inertia phase. During the final 
stage of the shift, the level of line pressure is again 
lowered. A spike in the transmission torque output when 
tends to occur at the beginning of the inertia phase is 
attenuated, the level of torque which is transmitted during 
the inertia phase is elevated and spikes which tend to be 
produced by the final engagement are reduced by the 
temporarily lowered final stage line pressure level.

Abstract: A constant dc current supplying circuit comprises a dc voltage 
supply (20), an inverter (30) providing an ac voltage from 
said dc voltage, and an ac-to-dc converter (50) providing a dc 
current from the inverter output and supplying the resulting 
dc current to a load (10). The inverter (30) includes a 
switching element (31) driven to turn on and off in order to 
repetetively interrupt the dc voltage for producing the dc 
current of which level is determined by on-off time ratio of 
the switching element (31). A comparator (100) is included to 
compare a level of the dc current supplied to the load with a 
predetermined reference level so as to provide a first output 
and a second output when the dc current level is below and 
above the reference level. Also included in the circuit is a 
feedback controller (110) which generates first and second 
feedback control signals, respectively in response to the 
first and second outputs from the comparator (100). The first 
and second control signals are defined as a train of pulses of 
varying duty ratio in order to increase and decrease on-off 
time ratio of the switching element (31) depending upon the 
sensed output dc current level, whereby controlling to 
gradually increase and decrease the output dc current towards 
the reference level for maintaining the dc current thereat.

Title: Procedure for reestablishing the original cell sequence, in particular in an atm switch, as well as output module for that switch
IPC: H04L12/56
Filed: 1990-12-08
Abstract: State of the art (not public): In order to load an ATM switching network as evenly as possible (even in the short term) and thereby minimise cost, the consecutive cells of one and the same connection are switched through to the exit via as many different paths as possible. 
<??>Technical problem: Reciprocal overtaking of consecutive cells must be avoided or corrected. 
<??>Fundamental principle: Each cell is held at the output until it is ensured that no preceding cell can still be temporarily stored in the switching network. Before the cell is forwarded, a check is carried out to ascertain whether, among the cells leaving the switching network at a later stage, a preceding cell is still present which is to be forwarded before it. 
<??>Implementation: Sequence numbers are assigned to the cells on the input side (either on an individual connection basis or not). On the output side, a buffer memory (1) is provided which is operated at least partially (1, ..., d) in the manner of a shift register and thereby produces a predefined delay. Before the output of a cell, at least the part of the buffer memory which is operated in the manner of a shift register is interrogated to ascertain whether a cell registered at a later stage is to be output earlier. If it is, the two cells are exchanged.
