Title: Combined air and rubber spring
IPC: F16F15/02
Filed: 1987-04-03
Abstract: A combined air-rubber spring has a load-bearing plate 8 and a bell-shaped rubber component 1 which supports the load-bearing plate 8, consists of a hollow-cylindrical side wall 2 and an end wall 3 extending essentially radially, and is closed in a sealed manner by a base plate 4, extending radially, which, together with the side wall 2 and the end wall 3 of the rubber component 1, delineates a pressure chamber 5 which can be filled with air, the end wall 2 of the rubber component 1 consisting of a central, circular section 6 and an annular edge section 7 arranged coaxially about the central, circular section 6. To increase the vibration-damping and shock-absorbing effect of the spring, and to prevent failure of the spring in the event of an overload, the annular edge section 7 of the end wall 3 of the bell- shaped rubber component 1 is constructed as a truncated cone and one or more feet 9 project in the axial direction into the pressure chamber 5 from the central circular section 6 of the end wall 3 of the bell-shaped rubber component 1, the free ends of which feet 9 are at an axial distance from the base plate 4 when the spring is in the undeformed state, and the other ends thereof are firmly connected to the load-bearing plate 8. The pressure chamber 5 can additionally be partially filled with fluid 14, into which the feet 9 dip with a radially broadened section 15, arranged in the region of their free ends, to improve even further the damping characteristics of the spring.

Patent EP-0254387-A3 (EP)
IPC: H03M11/08
Filed: 1987-04-14
Abstract: A method and apparatus for enhancing the operation of 
computer keyboards is disclosed. The invention allows 
touch-typing of nontouch-type keys by detecting a triggering 
sequence in the touch-type keys. For example, by holding 
down the Space Bar while depressing and releasing a second 
key and before release of the Space Bar, the Space Bar is seen 
to act as a Control key. Furthermore, the functions of non­
touch-type keys may be superimposed upon touch-type keys 
and accessed in a similar manner. The invention interprets 
make codes which are generated by the keyboard when a key 
is depressed and a break code which is generated by the key­
board when a key is released. If a triggering sequence of 
codes is detected, then the normal function of one of the 
touch-type keys is altered.

Title: Multitrack bar code and associated decoding method
IPC: G06K19/06
Filed: 1988-10-12
Abstract: A multitrack bar code and associated decoding method. 
Data are encoded into a multitrack bar code according to 
numerical values which correspond to the characters composing the 
data. The numerical values are combined into words and 
corresponding binary strings are chosen, the parity of each 
binary string being chosen according to the order of the row 
being encoded. Each row also includes a row check character, and 
the first row contains a character which checks the number of 
rows encoded and a data check sum on the data character values. 
If desired, column check sums can also be computed on each of the 
data-bearing rows in the multitrack bar code. The multitrack bar 
code can be encoded according to a numeric shift code when 
strings of numeric data of at least eight decimal digits are 
encountered. An alphanumeric shift character causes the 
multitrack bar code to return to the alphanumeric mode.

Title: Reception device
IPC: B23B31/02
Filed: 1988-10-06
Abstract: The reception device has a spindle body (1) with external thread (1b). The spindle body (1) is surrounded by a piston (4) and a reception space (6) filled with hydraulic medium (7). A drilling tool (15) can be screwed to the spindle body (1), this drilling tool (15) being supported on the piston (4). The piston (4) supported on the medium (7) thus puts the medium (7) under pressure. To release the drilling tool (15), the pressure of the medium (7) is reduced by means of a manually operable control element (11) by connecting the reception space (6) to a compensation space (9). The drilling tool (15) can thus be removed from the reception device without an auxiliary tool and without considerable application of force.

Title: Opto-electronic system for determining direction and speed of a vehicle by emission of laser beams, and the simultaneous measurement of the rotation
IPC: G01P3/36
Filed: 1988-01-12
Abstract: The explanations and descriptions contained in the present ad­
ditional patent concern some improvements devised for the "op­
tical-electronic system for determination of direction and 
speed of a vehicle by emission of an internal laser beam" for 
which two former patent applications, namely nr. 9/82810 A/84 
of Sept. 19th 1984 and nr. 9/82809 A/86 of May 27th, 1986 we­
re submitted by the same author, UGO Licinio (25, via Valdiri­
vo, Trieste, Italy). The above-mentioned improvements are a 
series of structural changes of the optical system, similar to 
the one described in the two former patents, but resulting in 
a smaller size of the measuring instrument without any change 
in the performances reported in the two former descriptions. A 
proposal is also made to use such small-sized optical device 
contemporaneously for the detection and measurement of its 
possible rotations around the internal axis parallel to its 
straight motion.  
     By resorting to the Sagnac principle, therefore, the optical 
device used in order to determine the speed and direction of a 
vehicle in motion may thus include some performances as a la­
ser gyroscope. A description is also made of further improve­
ments of the optical device and the elctronic computer, achi­
eved from a consequence of the Fitzgerald contraction princi­
ple that makes equal the time duration of the two forward and 
back, consecutive travels of a beam running once parallel and 
once perpendicular to the motion of a body, as demonstrated 
by the Michelson-Morley experiment. A blocks electric diagram 
is also described, with the changes introduced in order to 
improve the computering system, taking into account the new 
 
 
situations created by the various modifications aimed to ob­
tain a possibility of measurements of straight speed and tran­
sverse rotations speed, even though the measuring instrument 
is remaining static.
Patent EP-0327914-A3 (EP)
Title: Calorimetry system
IPC: G01N33/00
Filed: 1989-01-30
Abstract: A calorimetry system for measurement of the 
heating value of solid fuel (e.g. coal), having a combustor 
24 and a mixing unit 30 wherein heat from combustion gases 
is transferred to air. The system has a gravimetric feeder 
64 for providing coal at a measured mass feed rate; the coal 
including any moisture present therein. The coal is 
pulverized in an air-driven mill or pulverizer 14 which is 
fed coal from the feeder. The milled coal from the 
pulverizer is separated by a cyclone separator 16 into two 
streams; one carrying coal and air mixed together in a 
controlled ratio to the combustor. The air which drives the 
separator, together with fines of the coal and moisture is 
fed to an afterburner 26 of the combustor so that the 
thermal dynamics of the entire coal stream is taken into 
account in the measurement of the heating value thereof. 
Instrumentation in the system measures the flow rates of 
cooling air, primary air which carries the coal streams into 
the combustor and secondary combustion air as well as the 
mass flow rates of the coal into the combustor as measured 
with the gravimetric feeder. A computer is provided with 
input/output devices responsive to measuring instruments 
(thermocouples and pressure gauges) for controlling the 
feeding of the coal and fuel gases (propane) during 
initiation of combustion, and for computing the heating 
value of the coal. The propane flow is used to bring the 
combustor up to temperature for supporting spontaneous 
combustion of the coal and to initially calibrate the 
system.
