Patent EP-0145912-A3 (EP)
IPC: C07C67/00
Filed: 1984-10-30
Abstract: A process wherein coal is reacted with a hot gas stream 
to produce acetylene. The process comprises the sequential 
steps of reacting a fuel, oxygen and steam under controlled 
conditions of temperature to produce a hot gas stream princi­
pally comprising hydrogen, carbon monoxide and steam 
along with minor amounts of carbon dioxide, and essentially 
free of O, OH and O₂. The hot gas stream is accelerated to 
a high velocity and impinged upon a stream of particulate 
bituminous or subbituminous coal and thereafter the mix­
ture of hot gas and coal is decelerated to a velocity of from 
about 150 to 300 feet per second. The amounts of the 
streams of particulate coal and hot gas are controlled to 
produce in the reaction zone a pressure in the range of from 
about 10 to 100 psia and a temperature of from about 1800° 
to 3000°F. The mixture of coal and hot gas is maintained at 
that pressure and temperature for a time of from about 2 to 
30 milliseconds to produce a product stream including char 
and acetylene. The temperature of the product stream is 
then reduced to less than about 900 °F in a time of less than 
about 2 milliseconds to substantially arrest any further reac­
tions and the acetylene is recovered therefrom. The char is 
recovered and used as at least a part of the fuel used to 
produce hot gas.

IPC: B04C11/00
Filed: 1984-01-24
Abstract: A hydrocyclone comprising a frusto conical feed box 
extension (G), a feed box (D) attached to the larger end of the 
feed box extension, the feed box having a tangential feed 
pipe (E), an overflow box (B) positioned over the feed box 
and including an overflow pipe (C) and a vent pipe (M), and a 
fish tail (J) at the narrower end of the feed box extension, 
characterised in that a pressure compensating valve (10) is 
positioned in the vent pipe (M), and operation of the valve is 
dependent on the pressure within the feed pipe. The 
pressure compensating valve comprises a valve member 
(11) biased to an open position against a diaphragm (14) 
located in a pressure chamber, one side (19) of the dia­
phragm being in fluid communication with the feed pipe 
whereby variation of the pressure within the feed pipe 
causes the diaphragm to displace the valve member to a 
partially or totally closed position against an associated 
valve seat (24).

IPC: F41A3/62
Filed: 1984-11-15
Abstract: A machine pistol includes means for retarding blow­
back of the slide assembly (100). The pistol has both right 
hand and left hand stocks (12, 13) to enable the weapon to 
be fired from a comfortable visual sighting position at eye 
level with the wrist axes perpendicular to one another. The 
slide assembly (100) includes a bolt (110) which carries the 
firing pin (129), extractor and elector and which reciprocates 
relative to the receiver (20) and barrel (60), and a tubular 
cylindrical muzzle sleeve (140) releasably connected to the 
forward end of the bolt (110) and which fits coaxially around 
the barrel (60). A coaxial helical spring (65) is provided 
between the barrel (60) and muzzle sleeve (140) to urge the 
muzzle sleeve (and bolt) to the forward firing position in 
which the forward end of the muzzle sleeve extends out­
wardly beyond the end of the barrel. A plurality of annular 
internal grooves (150) are formed in the forward end of the 
muzzle sleeve (140) so that the momentum of the escaping 
gases immediately following firing exerts a force against the 
sidewalls (152) of the grooves to retard blowback of the slide 
assembly (100).

Abstract: The invention describes portable cooling and heating devices and their process of operation in accordance with the adsorption principle utilizing the adsorption substance pair of zeolite-water. The devices operate without substance and heat exchange from the environment, in that the evaporation heat originates from the solidifying heat of a non-evaporating amount of water and that the released adsorption heat is stored in the form of tangible heat of the zeolite filler. The ice which had been generated during the adsorption process is suitable for human consumption.

IPC: H04L5/14
Filed: 1985-12-19
Abstract: A two-wire bidirectional transmission system for trans­
mitting electrical signals simultaneously in opposite direc­
tions between terminals over a pair of wires wherein the 
transmitter at one terminal transmits a voltage signal over 
one of said wires while the transmitter at the second terminal 
generates a voltage signal over the same wire, the second 
wire being grounded at each end. Impedance matching 
resistors, that is resistors matched to the impedance of the 
two wires, are coupled between each of the transmitters and 
the wire upon which the voltage signal is generated. A 
subtractor circuit is provided at each of the terminals for 
linearly subtracting a signal proportional to one-half of the 
voltage transmitted and thereby receiving at each terminal a 
voltage signal equal to one-half of the voltage transmitted by 
the opposite terminal.

The outlet contains a restrictive structure (9), such as a sintered glass filter disc, on which a thin film of the condensed liquid forms. Liquid is drawn off through the restrictive structure (9) whilst the film is replenished so that a barrier layer of the liquid which seals the outlet (5) is continuously maintained.

Patent EP-0269878-A3 (EP)
IPC: B24B51/00
Filed: 1987-10-30
Abstract: A method and apparatus are provided for 
controlling a cam grinding machine and the like by 
kinematically modeling (FIGURES 10 through 21) the cam 
generating geometry of the grinding machine and using 
the kinematic model to convert cam lift data (FIGURES 
3A and 3B), which is related to the desired contour of 
a cam (12 or 14), to a form which is usable by first 
and second drive axis controllers (80 and 76). The 
cam lift data is analyzed (110) through the use of a 
fast fourier transform (FFT) (116) to thereby obtain 
FFT coefficients (118) which define the amplitude and 
frequency content of the cam lift data. Through a 
combination of the kinematic model and an inverse FFT 
procedure, an axis control function including a 
position control function (Eq. 1 and Eq. 14) is 
determined (128) for each axis. Dynamic compensation 
(130) of each axis is provided for system lags and 
inertia loads by altering the axis control function as 
a proportion of the axis velocity and acceleration 
(130), respectively. For each controlled axis an 
independent vector and a corresponding dependent 
vector containing axis control data is generated 
(132). During the actual control of first and second 
drive motors (72, 70) of the grinding machine, posi­
tion and velocity feedback signals are generated for 
each axis by feedback devices (82, 78). A master/­
slave control arrangement is provided between the two 
axes wherein the positional feedback signal (86) from 
one axis is utilized in the control of the other axis 
 
 
to eliminate time lags between control of the two 
axes.
Patent EP-0242069-A3 (EP)
IPC: C08J9/42
Filed: 1987-03-25
Abstract: The invention relates to the formation of 
semipermeable composite membranes produced by applying a 
curable silicone (polyorganosiloxane) water based micro or 
macro emulsion to a porous substrate, evaporating the aqueous 
components of the emulsions, and allowing the emulsified 
siloxane particles to coalesce and to crosslink to form a 
cured film on the porous substrate. Because the curable 
silicone water based emulsion is essentially free of organic 
solvent it can be applied to solvent sensitive natural and 
synthetic substrates. The composite membranes produced are 
useful for the separation of fluids.
