Patent EP-0121795-A3 (EP)
IPC: A61B5/08
Filed: 1984-03-09
Abstract: An inhalation apparatus for exposing small laboratory ani­
mals, e.g., rats, to a test atmosphere in such a manner that the 
animals are exposed to a uniform concentration of the test at­
mosphere containing substantially no exhaled materials.  
     The apparatus comprises an animal holding tube means 
capable of positioning the nose of an animal at a fixed point 
within the tube means. The tube means is provided with a test 
atmosphere inlet means located in the vicinity of the nose and 
an exhaust outlet means such that the test atmosphere can be 
inhaled by the animal then exhausted rearward of the nose of 
the animal.  
     A plurality of these animal holding tube means can be 
combined by connecting their inlet means to a first plenum 
duct that is in communication with a source of the test atmos­
phere and connecting their outlet means to a second plenum 
duct for exhausting substantially all exhaled materials and 
excess test atmosphere.

onto a polymer by feeding the monomer in the gaseous state 
onto the polymer while maintaining the polymer substantially in 
the solid state, an improvement wherein a radical polymeriza­

Patent EP-0121437-A3 (EP)
IPC: F23N5/00
Filed: 1984-04-02
Abstract: A control system for a boiler or furnace (2) extracts from 
the flue (4) a sample portion of the burnt flue gas. The level of 
unburnt oxygen therein is detected and compared with a 
stored reference level which, for the particular fuel supply 
rate, is indicative of efficient boiler or furnace operation. If the 
detected oxygen level differs from said stored reference level 
by more than a predetermined amount the relative proportion 
of fuel and air in the mixture is adjusted in the appropriate 
sense, prior to the burnt flue gas being re-tested. Before detec­
tion the sample portion is passed through a trap (18) having a 
condenser portion from which liquid condensed from the 
sample portion drains into a sump portion. The condensed 
liquid is automatically drawn from the sump portion at inter­
vals by a siphonic duct.

Title: Ternary signal scanning device
IPC: H04L7/02
Filed: 1986-06-02
Abstract: In a circuit arrangement for sampling a ternary signal, this ternary signal is divided by amplitude decision circuits into two binary signals and the binary sub-signals are sampled at m-times the rate of the symbol clock. The binary samples of each sub-signal are shifted through a shift register having at least m stages and intermediately stored in a buffer store for one period of the symbol clock. With the aid of a logic circuit it is then determined in which regions of the buffer store accumulations of identical binary values occur. Regions in which the accumulations always re-occur-the number of occurrences is checked by means of counters-are considered to be eyes of the ternary signal. In each clock period of the synbol clock, a sample falling within the eye of the ternary signal is transferred from each buffer store at an output of the circuit with the aid of a gate circuit.
