Patent EP-0176232-A3 (EP)
IPC: F24B5/02
Filed: 1985-08-22
Abstract: The invention relates to a solid fuel stove for use in 
heating. The stove includes a housing (1) which defines a 
heating chamber (2) therein. An opening (5) is provided in 
front wall (3) of the housing (1). Air inlet means (20) are 
provided in association with one or more walls (8,11) of said 
housing (1), the air inlet means (20) being in communication 
with one or more air passages (25) which are formed or 
provided on an inner surface(s) of at least one other wall 
(10,11) of the housing (1). The one or more air passages (25) 
may extend across inner surfaces (8a, 11a) walls (10,11) of 
the housing (1), from said air inlet means (20), to a position

IPC: B60R1/04
Filed: 1985-12-12
Abstract: A casing (61) has a transparent window plate (7) sealed 
therein. A reflector plate (12) is mounted on a 
diaphram (66) which forms a sealed chamber (72) with the 
base (64) of the casing. The casing (61) is mounted on a 
conventional mirror adjustment mechanism (80). A plurality 
of concial compression springs (73) urge the reflector plate 
(12) against the inside surface of the window plate (7) in 
the day position of the reflector plate (12). To move the 
reflector plate (12) for a day position to a night 
position, a pump (84) draws an optically dense light 
attenuating fluid from a reservoir (82) and pumps it into an 
annular chamber (78) and between the window plate (7) and 
reflector plate (12), to move the reflector plate (12) 
rearwards so that the fluid forms a masking layer between 
the reflector plate (12) and window plate (7). The masking 
layer extinguishes reflections from the reflector plate (12) 
in the night position. A solenoid valve (79) prevents return 
of the fluid to the reservoir (82) in the night position.

Patent EP-0277476-A3 (EP)
IPC: C08G63/685
Filed: 1988-01-05
Abstract: Multidimensional oligomers of the present 
invention are surprisingly useful for advanced 
composites because each generally has a use temperature 
greatly in excess of its curing temperature. The 
oligomers have essentially no arms, and comprise 
crosslinking phenylimide end caps condensed directly 
onto an aromatic hub (preferably, phenyl) through 
"commodity" polymeric linkages, such as amide, diimide, 
ether, or ester. For example, p-nadicimido­
benzoylchloride can be condensed with triaminobenzene to 
yield a multidimensional, crosslinking amide oligomer. 
Short chains of ether/carbonyl aromatic chains can be 
included, if desired. Methods for making these high-­
performance oligomers with ether/carbonyl aromatic 
chains use an Uhlman ether synthesis followed by a 
Friedel-Crafts reaction.

Abstract: Excellent stabilization of polypropylene (PP) fibers 
exposed to sterilization levels of gamma radiation, is 
obtained with a hybrid stabilizer having a N-(substitut­
ed)-1-(piperazin-2-one alkyl) group at one end and a (3,5-­
dialkyl-4-hydroxyphenyl)-α,α-disubstituted acetamide at 
the other. When this hybrid of a hindered amine with a 
hindered phenol is combined through a disubstituted alpha 
carbon atom of the acetamide in a single molecule, it 
affords the advantages of each group with respect to its 
stabilization against oxidation, but without the known 
inherent disadvantages of either group. This molecule is 
N-(substituted)-1-(piperazin-2-one alkyl)-α-(3,5-dialkyl-­
4-hydroxyphenyl)-α,α-substituted acetamide molecule ("3,5-­
DHPZNA" for brevity). 
The unexpected retention of tensile strength in 
3,5-DHPZNA stabilized PP fibers used in articles exposed 
to a sterilizing dosage level of gamma radiation, is of 
great practical value.

<??>This object is achieved by an elastic rod (12) of dielectric material being fixedly connected to a spring element (11) and carrying a plurality of coils (SP1 ... SP4) and a radiating part (13). Together with the spring part (11), a first coil (SP1) which is electrically connected to the said spring part (11) has a first length L1 =  lambda /4. A second coil (SP2), connected to the first coil (SP1), has a length L2 =  lambda /4.

A fourth coil (SP4) is wound from the end of the third coil (SP3) parallel to the second coil (SP2). A radiating part (13), having a length L4 = 3/8  lambda , is connected to the fourth coil (SP4). In this case,  lambda  is the mean operating wavelength of the relevant radio band. 
<??>A preferred area of application for the rod-shaped radio antenna is the Radio Network C of the German Federal Post Office. 
<??>The drawing shows a winding layout for the rod-shaped radio antenna.

Title: Phase difference measurement
IPC: G01R25/00
Filed: 1990-01-15
Abstract: Apparatus for measuring the phase difference between 
input signals X₁ and X₂ of equal frequency comprises 
quadrature sampling circuits, such as Digital Radio 
Frequency Memories (DRFMs) 1 and 3, having a common local 
oscillator 13. Analogue to digital converters 29,31,33,35,

digitising the in-phase and quadrature samples. The 
digitised samples are used in look up tables 39 and 41 to 
provide values of instantaneous phase which, preferably 
using modular arithmetic, are used to derive in an 
arithmetic circuit a number of values of phase difference 
between the signals X₁ and X₂.  
     The mean of the number of values of phase difference is 
then determined by the use of an accumulator circuit 
operating in conjunction with a divider circuit which is 
clocked at a sub multiple of the sampling clock 37.  
     In an alternative embodiment for higher speed operation, 
the analogue to digital converters 29,31,33,35 and look up 
tables 39 and 41 may be substituted by comparators arranged 
to detect the polarity of the samples and to provide a 
binary 1 or 0 to indicate the phase of the samples.
