Patent BE-901383-A (BE)
Title: Electronic control system for central heating boiler - is programmed according to building type, insulation heating system parameters, etc. and uses NTC resistance transducers
IPC: F24D19/10
Filed: 1984-12-27
Abstract: Three variable input signals are detected by accurate NTC resistance transducers; the temp. -tw- of the water leaving the boilder, the outside air to temp. -Tbuit - , and the required inside air temp. - Tbin. The relationship between these variables is defined by the equation: (TW-Tbin)/(Tbin-Tbout)=K, which includes a constant factor -k- which is a tatio between two ratio between two thermal resistances: the heat transfer resistanc between the boiler and the inside air, and the heat loss resistance between the inside and the outside air. - The transfer resistance depends on piping and radiator characteristics, etc, while the loss resistance depends on building structure, insulation provision, etc. The control panel enables programming of K factor, daylight timing, automatic frost protection, summer/winter switching, etc.

Title: Sugar extraction from beet - by feeding beet up a tower dolon which extraction fluid is sprayed
IPC: C13B10/10
Filed: 1972-01-14
Abstract: Beet pulp passed upwardly through the tower supported on radial vanes secured to a rotating shaft and co-operating with fixed vanes on the tower wall, and extraction fluid, sprayed downwardly through the tower, is collected as sugar soln. at the bottom of the tower. The pulp is supplied to the base of the tower by several screw presses having pref. perforated threads and sugar soln. collected from the bottom of the tower is mixed with pulp in the screw presses. The screw presses act to press sugar soln. from the pulp before it passes to the tower. Pref. the screw presses are inclined to radii of the tower and have equal length and diameter. Efficiency of sugar extraction is increased.

Abstract: METHOD OF TRANSMITTING INFORMATION AND        MULTIPLEXING DEVICE FOR EXECUTING THE METHOD                          Abstract A method for transmitting information from different sources over a common transmission medium is described.  Data from a first set of sources is transmitted as circuit - switched traffic in periodic time slots of sequential time frames.  The time slots are temporarily assigned to the sources and the size and position of any time slot within a frame cycle is determined by its respective assignment.  Data from a second set of sources is intermediately stored in a buffer store as store-and-forward traffic.  The data stored in the buffer store is sequentially extracted from the store and transmitted in the data stream in gaps left in the time frame between time slots in the circuit-switched traffic.  A new time slot is assigned to one of the first set of sources only if the remaining channel capacity available to the store-and-forward traffic will not be less than a fixed minimum value.

Abstract: The invention relates to the manufacture of urea-formaldehyde condensation polymers containing sulpho groups. The starting material is a urea-formaldehyde precondensate, and a condensation polymer of naphthalenesulphonic acid and formaldehyde is used as the acid catalyst for the subsequent polycondensation of the urea-formaldehyde precondensate. The peculiarity of this polycondensation is that the condensa-tion catalyst is incorporated into the polymer structure of the UF polymer.      The products obtained according to the invention are distinguished by improved surface affinity coupled with inter-particle porosity.        They can be used as fillers, as adsorbents, as carriers and as thickeners.

Abstract: ABSTRACT OF THE DISCLOSURE            A process and and arrangement for converting air into a gaseous mixture enriched with nitrogen includes passing a first stream of air through an adsorber which preferentially adsorbs oxygen from the admitted first stream and thereby dis-charges a second stream of a gaseous mixture having a higher pro-portion of nitrogen as compared with the first stream. Control means are positioned in the second stream to measure the oxygen content of the continuously discharging second stream and termi-nates the discharge of the same when the oxygen content thereof exceeds a predetermined value. Residual amounts of gaseous  mix-ture are then evacuated from the adsorber. An additional adsorber is connected with the first-mentioned adsorber to form a first stage with each adsorber being alternately charged with air in a cyclic-al operation. Additional stages are connected in series so that the effluent nitrogen-enriched gaseous mixture can be further en-riched to a final desired value.

Abstract: RADIOACTIVE WELL LOGGING SYSTEM WITH SHALE (BORON) COMPENSATION BY GAMMA RAY BUILD-UP             (D# 73,869-F) ABSTRACT OF THE DISCLOSURE          Earth formations in the vicinity of a well borehole are repetitively bombarded with bursts of high energy neutrons.          A radiation detector in a sonde in the borehole senses the gamma rays induced by the capture of thermal neutrons and sends signals representative thereof to the surface.  At the surface, two single channel energy analyzers, such as from 1.30 to 2.92 Mev and from 3.43 to 10.0 Mev, sense the forma-tion thermal neutron capture gamma ray response after each neutron burst.  The counts of thermal neutron capture gamma rays in these analyzers are used to distinguish between the presence of salt water and hydrocarbons, which is logged.          By controlling the repetition rate of the neutron source, measured counting rates in formations with relatively large thermal neutron lifetimes are emphasized, compensating for borehole effects which could otherwise give rise to erro-neous results in shale formations, which have a high boron content.

Abstract: ABSTRACT OF THE DISCLOSURE           A riding vehicle, such as a lawn mower, has a flexible apron positioned behind the rear wheels with a lower edge of the apron above the ground.  The mower can back up without impediment from the apron, unless an object is encountered.  In that case, the object contacting the apron pushes it against the rear wheels and the apron is pulled under the tires where it abruptly snubs the tires and prevents further backing motion.  To achieve this, the apron is supported by the mower through yieldable means which holds the apron above the ground until it contacts the wheels. The apron is also anchored to the mower to limit the extent of downward movement of the apron.  In a preferred form, the yieldable supporting means for the apron also is resilient so that the apron can be returned to the original position after it is released from the rear wheels, as by driving the mower forwardly again.  The apron is capable of stopping the mower securely and abruptly and reliably does so in a fixed, relatively short distance.  The apron also has a lower edge which is sufficiently stiff to cause an object encountered to move the apron against the rear wheels but is sufficiently yieldable so that the object, in the case of an animate object, will not be injured if partly caught under the apron when snubbed under the tires.
