Patent EP-0170212-A3 (EP)
IPC: C04B18/02
Filed: 1985-07-25
Abstract: The invention concerns a process for the production of 
aggregates starting from clay and from waste waters, dusts 
and/or muds deriving from the purification of industrial 
and/or civil wastes. According to said process, the waste 
waters, dusts and/or muds are mixed in ratios from 1 to 70% 
by volume with clay (from 99% to 30% by volume), the 
mixture is homogenized in the most uniform possible way, 
and then treated at high temperature in a rotary furnace. A 
foamed or not foamed aggregate is obtained which gives 
positive results to all washout tests, not only in the granular 
form but also after breaking or grinding. If the initial wastes 
contain metals, particular antipollution advantages are 
obtained.

Patent EP-0225705-A3 (EP)
IPC: G01R13/34
Filed: 1986-10-21
Abstract: The distribution with respect to time of an event defined 
by the waveform of a repetitive input signal having a magnitude 
that lies within a predetermined range of values is observed by 
generating a sample signal at least once during each repetition 
of the input signal, generating an n-bit digital timing signal rep­
resentative of the time of occurrence of a sample signal relative 
to the time of occurrence of the trigger signal, and sampling the 
repetitive input signal and generating a memory enable signal 
in the event that the magnitude of the input signal at the time 
of sampling falls within the predetermined range of values. The 
memory locations of a memory having 2 n  separately address­
able memory locations are allocated respectively to the 2 n  pos­
sible values of the timing signal, and the contents of a memory 
location of the memory means are incremented by one unit in 
the event that a memory enable signal is generated in response 
to a sample signal that is associated with the timing signal to 
which the location is allocated.

Patent EP-0277498-A3 (EP)
IPC: A23L7/10
Filed: 1988-01-13
Abstract: Quick cooking rice products are manufac­
tured in a low mechanical shear extrusion process by 
first pre-cooking a rice and water mixture in a 
preconditioner and then advancing the mixture along 
the length of an extruder sequentially presenting a 
cooking zone, a venting zone, a forming zone, and 
finally an extrusion die to yield an extruded prod­
uct. Venting of gaseous products removes a signifi­
cant amount of moisture from the mixture during the 
time that the latter passes between the cooking zone 
and the forming zone, and consequently the moisture 
content of the mixture within the cooking zone can 
be increased in order to reduce the total mechanical 
shear imposed on the mixture during the cooking 
process. The extruded product, once dried, closely 
resembles rice grain and readily rehydrates without 
exhibiting slimy or sticky characteristics, and has 
an increased tolerance to overcooking. A venting 
device has a rotatable screw for enabling gaseous 
materials to be discharged from the mixture while 
substantially preventing the escape of the mixture 
from the extruder barrel of the extruder.

Title: A vehicle security barrier
IPC: E01F13/00
Filed: 1988-03-17
Abstract: A vehicle security barrier (10) for 
selectively prohibiting a vehicle from accessing a 
preselected area and for otherwise controlling 
vehicular traffic. The security barrier (10) 
comprises a base (12) defining a travelway (14) 
over which a vehicle can be driven. The base (12) 
comprises a forward end portion defining an 
entryway (20) whereby a vehicle enters onto the 
travelway (14) and a rearward end portion defining 
a travelway exit (22) whereby a vehicle exits the 
travelway (14). The security barrier (10) further 
comprises a security gate (18) pivotally mounted 
on the base (12) for being selectively raised to 
obstruct the travelway (14) and prohibit a vehicle 
from exiting the travelway via the travelway exit 
(22). Reciprocal actuating means are also 
provided for selectively raising and lowering the 
gate (18). In the preferred embodiment, the 
reciprocal actuating means comprises a first and 
second fluid actuated cylinder (64A and B).

Title: Equipment for fast frame- and phase-synchronisation
IPC: H04J3/06
Filed: 1988-06-03
Abstract: A fast adjustment of sampling clock phase may be accomplished by calculating the values of the pre-oscillations and post-oscillations that would have been present at each sampling instant to form a correction value so that they may then be subtracted from the measured sample value and only the influence of the distorted unique word remains. Usable control information for readjusting the phase of the sampling clock may thus be derived after only one frame synchronization word has been detected. In a preferred embodiment, the required pre-oscillation and post-oscillation values are derived from the regenerated character data; rather than correcting the sample values themselves, correction values are derived which are used to correct quantities derived from the sample values. The transmission coefficients of the transmission path used to derive the required pre-oscillation and post-oscillation values from the regenerated characters may be either established a priori or derived from the equalization coefficients of an otherwise conventional adaptive equalizer.

Title: Chromatography apparatus
IPC: G01N30/30
Filed: 1988-08-25
Abstract: A thermal insulation liner is provided for a chromatograph 
oven. The liner is moulded as a single bucket-shaped component (1) 
from ceramic fibres, typically alumino-silicate, bound together 
with an inorganic binder. The heat capacity and thermal 
conductivity of this material are both very low. The inner layer of 
the oven can be rapidly cooled for fast throughput of analyses and 
there is low risk of hand burns when changing chromatograph 
columns. The inner surface is moulded as a smooth shape, assisting 
the flow of circulated air and thereby reducing hot spots. Thermal 
insulation for the injector and detector of the chromatograph are 
also moulded in together with entry holes and mounting points (3, 4, 
5, 6) to enable an inexpensive, easily assembled oven and 
chromatograph to be produced.
Patent EP-0310361-A3 (EP)
IPC: C07K16/00
Filed: 1988-09-29
Abstract: A novel tridentate conjugate has three chemical 
moieties, or tridentate members, attached through an 
appropriate spacer moiety. At least two of the 
tridentate members are relatively small molecules, 
usually less than about 7,000 Daltons in size. The 
particular appropriate spacer moiety selected for a 
tridentate imparts certain steric properties to the 
tridentate conjugate. In one embodiment, the binding of 
a macromolecular specific binding partner to one of the 
tridentate members sterically inhibits the binding of a 
different macromolecule to another tridentate member. In 
another embodiment, the binding of a first tridentate 
member to a macromolecule restricts the subsequent 
binding of a second tridentate member to a proximate 
location on the same macromolecule.
