IPC: H04B3/48
Filed: 1987-09-29
Abstract: A system for transmission loss comparison permits 
enhanced accuracy over a wider dynamic range by providing a 
reference channel including a transmitter, receiver, and 
transmission path therebetween, and a sample channel, 
including a transmitter, receiver, and transmission path 
therebetween. A feedback arrangement is provided for 
adjusting the outputs of both of the reference and sample 
transmitters in relation to the signal output of the 
reference receiver, so as to produce a desired signal level 
of the reference receiver's output over a given dynamic 
range, so as to compensate for loss over the reference 
transmission path. In this way, a comparator connected to 
the outputs of the two receivers receives inputs that are 
compensated for effects of losses over the reference 
transmission path.

Abstract: Apparatus and methods for use in measuring the 
moisture content of heavy-grade sheets of paper 
during their continuous manufacture. In one aspect, 
means employing infrared absorption techniques for 
determining the fiber weight per unit area of a sheet 
having a fiber weight of up to 1100 grams per square 
meter are provided. In another aspect, means 
employing infrared absorption techniques including

the indication is substantially independent on 
changes in the average temperature, and enables 
accurate measurement of the moisture weight per unit 
area of heavy grades of paper having moisture weights 
of up to 450 grams per square meter. The former 
aspect may be employed in measuring the moisture 
content of heavy grades of paper having moisture 
weights of up to 90 grams per square meter.
Patent EP-0286447-A3 (EP)
Title: Method and agents relating to prophylactic treatment of autoimmune diseases
IPC: A61K39/00
Filed: 1988-04-11
Abstract: Autoimmune diseases are the result of an immune response directed against a self antigen. Susceptibility to an autoimmune disease is conferred by antigen encoded within an allele of the MHC. A potentially susceptible individual is protected from developing the autoimmune disease by an antigen encoded within a second allele of the MHC. Individuals who have the allele for susceptibility, and lack the allele for protection are highly susceptible to manifestation of the autoimmune disease. The present invention provides a method for prophylactically treating individuals who are highly susceptible to an autoimmune disease. In the method, the individuals are tolerized by administration of a protective antigen encoded within the protective allele. As part of the invention, the sequences encoding the protective antigen(s), as well as the antigen(s) conferred susceptibility, are elucidated. The elucidation of these sequences allows for the synthesis of the antigens conferring these traits. These antigens may be used pharmacologically; in addition, they may be used to raise monoclonal antibodies. Monoclonal antibodies to these antigens are useful in diagnosis of susceptibility, and in elucidating the mechanisms by which antigens control the manifestation of the autoimmune disease. In addition, the sequence data allows the synthesis of nucleotide probes which are useful in diagnosis of susceptibility to the autoimmune disease.
Patent EP-0299769-A3 (EP)
IPC: G06T15/00
Filed: 1988-07-14
Abstract: This invention relates to a method for generating images 
by using a ray-tracing method.  
     In the case of the conventional method, a rectangular parallelepiped 
completely included in an object to be displayed is registered and 
subject to sampling although an intersection point between the ray and 
the object surface cannot exist there.  
     The method for generating images according to the invention registers 
only a cell containing surface 50 of object 44 among cells that are 
obtained by dividing region 42 containing object 44 to be displayed. The 
calculation of intersection points is performed only for rectangular 
parallelepipeds in which the surface exists. Thus, it is possible to 
reduce the time required for displaying object 44.

Patent EP-0306269-A3 (EP)
Title: Double-enveloped electric lamp
IPC: H01K1/26
Filed: 1988-08-30
Abstract: A double-enveloped lamp (10) has a shield (28) sur­
rounding a light-source capsule (20) within a thick-­
walled outer envelope (12) so that the lamp (10) may 
be safely operated without necessity of a protective 
fixture. In the rare event of a burst of the light-­
source capsule (20), the shield (28) absorbs and 
dissipates a portion of the burst energy sufficient 
to permit the thick-walled outer envelope (12) to 
remain intact and contain shards and other internal 
parts within the lamp (10).  
     In alternate embodiments, the shield (28) may be re­
inforced, such as with a wire mesh (50), or the outer 
envelope (12) may be reinforced, such as with a poly­
mer coating, or both. A thin-walled capsule (20) 
may be employed in combination with a shield (28) 
and thick outer envelope (12).  
     A lamp (10) in accordance with the invention provides 
the unexpected benefits of improved luminous efficacy 
and better color rendering characteristics, since 
the presence of an optimally positioned shield (28) 
causes the operation of the light-source capsule (20) 
to be more nearly isothermal.

Title: Printed circuit board relay
IPC: H01H50/28
Filed: 1988-11-25
Abstract: In a very small hinged-armature relay of the printed-circuit board relay type, with a dual-in-line connector layout, which relay must be designed for a very high number of operations, the problem exists of designing the armature return spring such that it can withstand the number of operations without any risk of fracture. This problem is solved in the case of the present relay such that the leaf spring, which is connected in a positively locking manner to the limbs of the U-shaped armature (13), and which acts as a return spring, runs approximately parallel to the said limbs and is connected in a force-fitting manner to the coil body (10) forming the relay structure, in contrast to the normal fixing on the corresponding limbs of the E-shaped magnetic yoke (12). In this way, the spring can have a length which is at least equal to the length of the limbs of the armature. In order to simplify production and assembly, the leaf springs of the individual limbs are connected via a lateral web to a single-piece, H-shaped spring (14).

Title: Discharge lamp
IPC: H01J17/04
Filed: 1989-09-25
Abstract: A discharge tube of the type wherein a voltage 
is applied across a pair of electrodes to cause a 
discharge between the anode side electrode and the cathode 
side electrode. In the new discharge tube, opposing end 
portions of said pair of electrodes are formed into a 
non-acute configuration, and a large number of concave or 
convex portions are formed on a surface at least of said 
cathode side electrode. A stabilized high discharge 
voltage can be obtained from an initial stage of 
discharging with a comparatively small distance between 
the electrodes. Further, since the surface area of the 
electrodes is great, exhaustion of the electrodes are 
dispersed, and the electrodes are superior in durability. 
Further, since the distance between the electrodes is 
small, the discharge maintaining voltage is low and the 
energy loss is decreased.
