Patent EP-0268145-A3 (EP)
Title: Swivable caster
IPC: B60B33/00
Filed: 1987-11-04
Abstract: A swivable caster (10) includes plastic wheel means (16,17) rotatably mounted on a plastic stem (25) at the lower end thereof. Near its upper end the stem (25) is provided with an annular groove (27) having a nylon split ring (15) disposed therein and having its peripheral portion disposed outside of the groove (27). This peripheral portion engages a downwardly facing shoulder (35) that extends inward from the internal wall forming a socket (11) that receives the stem (25). Engagement of the split ring (15) with the shoulder (35) limits insertion of the stem (25) into the socket (11). During this insertion the split ring (15) is compressed radially so that is acts as a friction menas to hold the stem (25) in the socket (11) and also provides a bearing for swiveling of the stem (25).
Patent EP-0269068-A3 (EP)
Title: Aerosol package
IPC: B65D83/14
Filed: 1987-11-24
Abstract: The aerosol container has two separate chambers (11, 12) for different components (A, B) which are to be mixed during use, the two chambers (11, 12) being arranged one above the other and being connected to each other by a connection channel (21), which can be opened during use, in such a way that the opening of the connection channel (21) can be produced by mechanical movement of the chambers (11, 12) relative to each other, and a discharge valve (13), which can be actuated independently, being assigned to the upper chamber (11). In order to be able to construct the lower chamber more easily, the latter is filled with a first component (A), in particular hydrogen peroxide, and a first propellant (T1), in particular butane, propane or the like, and the upper chamber (11) is filled with a second component (B), in particular hair dye or the like, and a second propellant (T2). Said propellant (T2) causes a smaller pressure, which is sufficient for discharging the component mixture through the discharge valve (13), inside the upper chamber (11) than the propellant (T1) in the lower chamber (12). The purpose of the latter propellant is merely to press the first component (A) out of the lower chamber (12) into the upper chamber (11), mixing it with the second component (B), when the connection channel (21) which is common to both chambers (11, 12) is opened. Finally, the connection channel (21), consisting of only three plastic components, is also of importance. <IMAGE>
Patent EP-0237201-A3 (EP)
IPC: C09J7/22
Filed: 1987-02-13
Abstract: The receptivity of shaped polymer articles (e.g., 
self-supporting films of polypropylene) to subsequently 
applied organic coatings is enhanced by exposure to an 
electrical discharge in the presence of a chlorocarbon or 
chlorofluorocarbon gas, thereby providing an extremely thin 
chlorine-containing surface layer in which the Cl : C ratio 
is inversely related to the distance from the face of the 
layer. Preferred embodiments of the invention include tape 
products in which the primed surface of the backing is 
coated with a pressure-sensitive adhesive or a low adhesion 
backsize.

Patent EP-0260113-A3 (EP)
IPC: G05D1/04
Filed: 1987-09-08
Abstract: An ultrasonic height control system for an agricultural 
machine utilizes a transmitter/receiver transducer system 
(MUS, LL, L, CA, CB, R, RR) with signal processing in a 
microprocessor (P). The transmit-receive time elapse is 
used in further signal processing (including averaging of 
samples (Stage C)) to determine the measured height of the 
transducer above the soil. If the height is not correct 
then an error signal E ar  can be used through automatic 
control (Fig 7 and 5 D.) to adjust hydraulics on the 
machine to reset the desired height. When a field is 
other than firm and level, a problem exists in monitoring 
the received relected signal (R x ) and analysing 
accurately the point in the signal trace which is 
representative of the true leading edge of the reflected 
signal because of background noise and varying degres of 
soil reflectivity. The envelope (A₁) of the amplitude 
of the received signal is monitored and first and second 
time values (t₃ and t₆) are recorded respectively when 
the amplitude envelope exceeds a threshold value and 
subsequently when the amplitude envelope falls below a 
threshold value. Computation is made of a reference time 
value (t ref ) falling between the recorded time values 
and this reference time value is used in the 
microprocessor (P) for providing an error signal (E) for 
machine adjustment purposes. Preferably, a delay 
controller (Fig 7) delays a machine adjustment for a time 
inversely proportional to the magnitude of the detected 
error and monitors for persistence of the error.

Title: Vector calculation circuit capable of rapidly carrying out vector calculation of three input vectors
IPC: G06F7/509
Filed: 1988-03-03
Abstract: In a vector calculation circuit for use in a 
vector addition of first, second, and third vectors each 
of which is composed of an identical number to one 
another, a first adder circuit (26) comprises a carry 
save adder which carries out a carry save addition of a 
set of three components selected from the first through 
third vectors to produce a local sum and a carry 
collectively as a result of the carry save addition. 
The local sum and the carry is successively summed up by 
a second adder circuit (27) to produce a primary sum 
which forms an output vector. The primary sum may 
successively be sent back to the first adder circuit as 
the third vector. A selector circuit may be connected 
to the first adder circuit to select the first through 
third vectors and a fixed value of zero and to 
selectively add either two of the first through third 
vectors or three of them. Alternatively, a pair of 
selectors may be included to select either the first and 
the second vectors or the local sum and the carry.

Abstract: The present invention provides a logic synthesis method and 
system which begins (block 15) with a set of register transfer 
statements describing the desired logic. These statements are 
converted to expressions in prefix form (blocks 16, 17). Next,

19) to a set of logical function blocks, some of which may 
not be primitive blocks. Logical reduction is performed on the 
global set of any remaining primitives (block 20). The output 
of the above process is then used to synthesize the logic 
circuit (block 21).

Patent EP-0322925-A3 (EP)
IPC: B01F3/04
Filed: 1988-12-30
Abstract: Gas dispersion in a liquid is enhanced by 
combining the gas and liquid in close proximity to a 
venturi or other flow constriction means (2) used to 
create supersonic flow velocities and subsequent 
deacceleration to sub-sonic velocity. When a 
venturi is employed, the gas-liquid mixing occurs in 
the converging portion (3) of the venturi or upstream 
but in close proximity to said venturi. Turbulent 
flow conditions upstream of the venturi or other 
flow constriction means adequate to disperse the gas 
uniformly in the liquid are not required and, 
surprisingly, the gas and liquid need not be 
uniformly dispersed prior to acceleration to 
supersonic velocity.

Abstract: A protective air control system for an air turbine (73) motor 
having air bearings (72) ensures pressurized air is supplied to the 
air bearings (72) whenever the air turbine (73) is being driven. In 
one embodiment, a sensing device (81) monitors the air pressure supplied

predetermined amount. In another embodiment, a check valve (88) is mounted 
to divert a portion of the turbine air to the bearings (72) when the 
bearing air pressure is below the turbine air pressure. The protective 
system can be used with an electrostatic rotary atomizer coater (10).

Abstract: This invention provides a switched limiter (10) with 
variable attenuation designed with monolithic GaAs p-i-n 
diodes (16, 18, 34) and n-i-p diode (36). Greater than 30 dB 
of small-signal variable attenuation is achieved at X band 
frequencies, with a minimum insertion loss of 0.5 dB. The 
variable attenuation switched limiter (10) provides 15 dB of 
isolation to a +30 dBm input signal to the input terminal 
(12). Under bias conditions that result in variable 
attenuation, the variable attenuation switched limiter input 
impedance remains matched. When used as a passive limiter, 
7 dB of limiting has been achieved for a +30 dBm input signal 
at 10 GHz.
