IPC: A61M5/168
Filed: 1986-01-16
Abstract: A removable programmable element is used to control 
operation of a delivery unit, which unit delivers a therapeutic 
agent to a patient. The programmable element is program­
med, while removed from the delivery unit, by a computer 
that is operationally independent of the delivery unit. The 
delivery unit requires no microprocessor and can include a 
plurality of channels for effecting independent delivery of 
therapeutic agents in each channel under the control of the 
programmable element. The programmable element is 
programmed with respect to available protocol information, 
including patient history, needs and tolerances, as well as 
therapeutic agent parameters, to thereby establish a flow 
profile that is customized for a particular patient during each 
moment of each day. Patient demand for therapeutic agents 
can also be accommodated with safeguards being included 
to assure proper dispensing of the demanded agents.
Patent EP-0193161-A3 (EP)
IPC: C07K14/575
Filed: 1986-02-25
Abstract: Antibodies which contain reduced sulfhydryl groups in 
proximity to the carboxyl terminal end of their heavy chain 
are coupled to another moiety which has an available 
sulfhydryl for forming a disulfide bond with the antibodies. 
IgM is a typical antibody which contains a suitable structure 
by virtue of its cysteine residue in proximity to the carboxyl 
terminal end of its heavy chain. A typical hybrid is formed 
with IgM and the A chain of a toxin such as ricin by the 
formation of a covalent disulfide bond therebetween. Use of 
antibodies having structures such as IgM result in hybrid 
formation in which the moiety joined to the antibody is site 
directed with respect to its bonding location on the antibody. 
Such hybrids have utility including in vivo therapeutic 
applications in which the functionality of the antibody is not 
deleteriously impaired by the moiety bonded thereto.

Title: Snow-grooming vehicle with a ground working device adjustable in height, particularly a rotary snow cutter
IPC: E01H4/02
Filed: 1986-07-29
Abstract: The invention relates to a track maintenance vehicle having a levelling attachment secured to a transverse carrier member at its rear. The levelling attachment faces downwards and is at least partially flexible. For achieving satisfactory levelling of relatively loose snow as well as of encrusted or compacted snow, the levelling attachment comprises a leading portion of triangular cross-sectional shape secured to the transverse carrier member along a first triangle side. The second triangle side of this portion is formed as a rigid compaction surface extending downwards and rearwards from the transverse carrier member. Connected to a rear portion of the compaction surface is a plate-shaped flexible portion extending substantially parallel to the second triangle side in the relaxed state, and in a substantially horizontal direction when under load.
Patent EP-0196784-A3 (EP)
IPC: G01L9/00
Filed: 1986-02-28
Abstract: An optical pressure sensor comprises a resiliently 
flexible diaphragm and a rigid transparent cover plate 
mounted substantially parallel to the diaphragm and spaced 
therefrom by a collar so as to form a cavity between them. 
The opposing surfaces of the plate and diaphragm within the 
cavity are reflective, and form between them a Fabry Perot 
cavity, with the transparent cover plate enabling light to 
enter and escape from the cavity. The pressure to be sensed 
is applied to the diaphragm to cause it to flex and conse­
quently to vary the Fabry Perot interference pattern accord­
ing to changes in the pressure. The cavity is very thin, e.g. 
less than 1 micron between diaphragm and cover plate, and 
this can be formed cheaply by manufacturing the diaphragm 
from semi-conductor material such as silicon, and etching it 
to form the cavity.

Patent EP-0232007-A3 (EP)
IPC: G08C19/02
Filed: 1987-01-08
Abstract: Optically generated signals are processed to form a two-wire 
4-20 mA signal by generating (U7) a control signal having pulses at a 
selected frequency to drive a light emitter (10) which generates light pulses, 
transmitting the light pulses to a light detector (20) over a transmission line 
(15) having variable attenuation to form a sensor signal, and amplifying the 
sensor signal in an operational amplifier (U1). The variations in attenuation 
follow a process variable to be measured. To save power the amplifier (U1) 
has a low-current mode into which it is switched whenever no pulse is 
present in the sensor signal. The amplifier (U1) is switched into a 
high-current mode only when a pulse is present in the sensor signal. 
Switching is controlled by the control signal for the light emitter (10). Peaks 
in the signal from the amplifier (U1) are sampled and held (C1,CR1,S1) and 
then subjected to low pass filtering (R15,C2) to remove the selected 
frequency component and leave a cyclic filtered signal. The amplifier (U1) is 
driven towards ground by a feedback clamping signal which changes slowly 
with respect to the cyclic filtered signal and is generated by feedback 
means (U4,U3d). The filtered signal triggers a multivibrator (U10) to form a 
pulse signal having pulses of fixed length and amplitude of each cycle of 
the filtered signal. The pulse signal is then averaged 
(R22,R42,R34,C20,C14,C15) with respect to its voltage, subjected to zero 
adjustment (U11b,R24) and span adjustment (U11a,R28) and then converted 
(40) to a two-line 4-20 mA current signal.

Abstract: A method of manufacturing a thick multilayer board. Intermediate layers are formed by two consecutive head boxes disposed on a fourdrinier wire, in which layers the pulp suspension consistency is so high that the forming pulp layer reaches in a head box slice or immediately after it such a fibrage degree that fibres cannot significantly move themselves as regards to one another. Dewatering of both pulp layers takes place though a fourdrinier wire.

Title: Process for the thermal elimination of waste materials
IPC: F23G5/46
Filed: 1988-08-10
Abstract: For the thermal elimination of waste materials, such as e.g. sewage sludge, special waste or the like, use has thus far been made of conventional waste burning techniques, in particular with grate firings. Such elimination methods are ultimately not environmentally tolerable and are also not economical. In order to be able to eliminate such waste materials environmentally tolerably and yet economically, it is proposed according to the invention to burn the waste materials, possibly after their comminution and possibly after their drying or preheating in a cyclone furnace (combustion cyclone or melting cyclone of high power density), at extremely high temperatures above 1500 DEG C, forming a molten slag (18) low in harmful substances and a hot waste gas (19), in which gas the useful substances and/or harmful substances contained in the waste materials evaporate, there being separated, separately from one another, from the waste gas, in each case by partial condensation, on the one hand dusts (25) enriched with useful materials and on the other hand dusts (29) enriched with harmful substances.

Abstract: A computer-aided method for predicting the

prepreg material. A graphic display is generated 
incorporating the initial thickness needed at each 
location on the prepreg material to provide the desired 
final thickness of the three-dimensional shape with 
controlled fiber distribution throughout the shape.

Abstract: A firearm, generally of the automatic or semi-automatic 
type, has a reciprocating breech block (44) normally 
biased into closed position by a primary recoil 
absorption system including a spring (100). A 
secondary spring-biased recoil absorption system (50, 
Figs 1 to 5; 50′, Figs 6 to 10; 50″, Figs 11 to 14) is 
provided co-operating with the primary one during a 
portion of the retraction stroke of the block (44) to 
slow down the movement of the latter before becoming 
inactive while the primary system (100) slows the block 
to a stop and reverses its direction and then becoming 
active to once again co-operate with the primary system 
during a portion of the return stroke of the block (44) 
to speed up its return to its original position. A 
method for controlling the movement of the breech block 
in the aforementioned type of weapon during its firing 
cycle comprises supplementing and abetting such 
movement during its initial and final stages by a 
secondary spring-biased recoil absorption system (50, 
Figs 1 to 5; 50′, Figs 6 to 10; 50″, Figs 11 to 14) 
co-operating with the primary one while, at the same 
time, leaving the primary system solely responsible 
during the remainder of the cycle to stop the block and 
reverse its direction.

the last, location means whereby the last may be 
accurately located relative to said datum point on 
associated footwear-making machinery.
