Patent EP-0092969-A3 (EP)
Title: Pressure swing adsorption process and apparatus
IPC: C01B3/56
Filed: 1983-04-20
Abstract: A high pressure gas stream having a hydrogen content of up to about 90 mol percent is passed to a separator containing a permeable membrane capable of selectively permeating hydrogen. The separator is used to achieve a bulk separation of the desired hydrogen from impurities contained in the gas stream. The separated hydrogen is recovered at a reduced pressure and is passed to a pressure swing adsorption system adapted for operation at said reduced pressure. The off-gas from the separator is recovered essentially at the higher pressure of the gas stream. A portion of the off-gas is throttled to a lower pressure, with appropriate power recovery, and is passed to the pressure swing adsorption system as a co-feed gas, thereby contributing to the recovery of purified hydrogen product and to a reduction in the operating costs for the desired hydrogen separation and purification. The remaining off-gas is recovered as a relatively high pressure fuel or feed gas for other purposes.

Title: Process for preparing urea
IPC: C07C67/00
Filed: 1984-11-06
Abstract: Process for preparing urea in which,
 in a synthesis zone, at a pressure of 125-350 bar and at the temperature belonging thereto, a urea synthesis solution containing carbamate and free ammonia is formed from carbon dioxide and an excess of ammonia,
 in a first decomposition step, at synthesis pressure or lower, a part of the carbamate is decomposed by supply of heat and the gas phase obtained in this process is condensed in a first condensition zone,
 in a second decomposition step, at a pressure of 4-40 bar, a further part of the carbamate still present is decomposed by supply of heat and the gas phase formed is separated off,
 in a further step, the remaining carbamate is removed in the form of a gas mixture containing ammonia and carbon dioxide, and this gas mixture is processed to form a solution of ammonia and carbon dioxide in water,
 and the remaining urea-containing solution is processed to form a concentrated urea solution. 
<??>The urea solution to be concentrated is introduced into the tubes of a shell and tube heat exchanger, the gas mixture from the second decomposition step is led into the shell side of heat exchanger at the end opposite the place where the urea solution to be concentrated is fed, the solution of ammonia and carbon dioxide in water is fed to the said shell side at a place located between the inlet for the gas mixture and the inlet for the urea solution to be concentrated, and the condensate is discharged from the shell side at the end where the urea solution is led into the tubes.
Patent EP-0141645-A3 (EP)
IPC: A23K1/18
Filed: 1984-10-31
Abstract: A dry hard canine biscuit having visually apparent, 
discrete particles, which contain (i) meat an/or meat by-pro­
duct and optionally (ii) farinaceous material and/or textured 
vegetable protein, distributed substantially uniformly 
throughout the biscuit. The dog biscuit is obtained by blen­
ding the non-fat solids portion of the canine biscuit dough 
with the particles which are substantially inert with respect 
to the dog biscuit dough, mixing the dry-blended mixture 
with water and with the fat portion of the pet biscuit dough to 
form a dough, forming the dough using low shear into pie­
ces, and baking and drying the formed pieces to obtain a mi­
crobiologically stable product which can be packaged with­
out a barrier material. The particle inertness is made pos­
sible by using particles having: (i) a moisture content of 35 
percent by weight or less and (2) a water activity which is 
less than the water activity of said biscuit dough. There is a 
substantial absence of particle color bleed into the biscuit. 
An example of the textured vegetable protein is textured 
soy protein; and an example of the farinaceous material is 
wheat. The discrete, visually apparent dehydrated particles 
enhance the palatability and visual attractiveness of the dry 
biscuit.

Patent EP-0150998-A3 (EP)
IPC: G01F1/22
Filed: 1985-01-25
Abstract: A flow indicator (10) that can visually indicate to an im­
plement operator whether or not there is an equal flow rate 
of liquids through multiple liquid outlet lines (11) on the im­
plement (12). The flow indicator (10) includes wall portions 
defining a manifold (18) adapted to be connected in the sys­
tem to receive liquid output from a pump (15), and trans­
parent generally parallel closely spaced tubular members 
(21) having similarly sized through openings (23) com­
municating with the manifold (18), increasing in diameter 
from their inlet ends (22), and having outlet ends (24) coupled 
to the outlet lines (11). Normally, liquid is pumped into the 
manifold (18) and flows out the tubular members (21) with 
equal flow rates so that similarly sized indicating members 
(26) visible in the tubular members (21) will be horizontally 
aligned. If the operator observes one indicating member (26) 
out of alignment, this will indicate that one of the outlet lines 
(11) is obstructed and in need of attention.
Patent EP-0175530-A3 (EP)
Title: Article or seed counter
IPC: G06M1/10
Filed: 1985-09-09
Abstract: Seeds falling down a chute pass between two spaced windows (38, 40) and two spaced mirrors (34, 36) facing each other across the width of the chute. A linear array of seven radiation emitters (CR1-CR7) direct a beam of radiation across the seed path through a slit aperture in the window (38). The beam passes through a slit aperture in the window (40) to a pair of radiation detectors (46, 48) connected in parallel and providing a signal representing the amount of radiation falling thereon. Because of the number of emitters (CR1-CR7) in the linear array, the beam of radiation is diffuse and non-collimated so that no seed can be in the shadow of another and the integrated reduction in radiation falling on the detectors (46, 48) accurately represents the number of seeds passing through.
