Patent EP-0143616-A3 (EP)
IPC: H04B1/58
Filed: 1984-11-22
Abstract: A hybrid circuit (38) having high return loss and high 
transhybrid loss is disclosed. An operational amplifier (39) is 
employed in a feedback configuration. The receive port (30) of 
the hybrid circuit is applied to the non-inverting input of the 
amplifier while the center-tap of the secondary winding of the 
hybrid transformer is applied to the inverting input of the 
amplifier. Most noticeable is the omission of an impedance 
setting resistor at the output of the operational amplifier. 
The circuitry connected to the transmit port (29) and the two-­
wire bidirectional port (24) of the hybrid circuit are of con­
ventional design.

Title: Polysiloxanes, process for preparing them and their use
IPC: C08G77/44
Filed: 1985-01-22
Abstract: Organopolysiloxanes which are crosslinked by high energy radiation consisting essentially of siloxane units of the formulas: (a) HR1C=CR2COOR3SiR2O1/2, (b) HSR4SiRO and (c) R25SiO where R is a monovalent hydrocarbon radical or a halogenated monovalent hydrocarbon radical, R1 is hydrogen or a phenyl radical or a halogenated phenyl radical, R2 is hydrogen or an alkyl radical having from 1 to 4 carbon atoms per radical and R3 is a hydrocarbon radical or a halogenated hydrocarbon radical, R4 is a divalent hydrocarbon radical, R5 is the same as R or a hydrocarbon radical substituted with the HR1C=CR2COO group, where R1 and R2 are the same as above, in which two siloxane units of the formula HR1C=CR2COOR3SiR2O1/2 are present per molecule. These organopolysiloxanes are prepared by equilibrating the corresponding siloxanes in accordance with the conventional methods known in the art. These organopolysiloxanes can be crosslinked by high energy radiation, for example, ultraviolet radiation, to form coatings on paper for releasing tacky substances or as coatings on optic fibers and as photocuring sealants for electronic components.
Patent EP-0172464-A3 (EP)
IPC: H01L31/10
Filed: 1985-07-31
Abstract: The quantum regime and its properties are described 
and applied in the invention of a diode, termed a Femto 
Diode, responsive to light frequencies. In the quantum 
regime the conventional concepts of electrical resistance, 
resistive loss, and capacitance do not apply.  
     The Femto Diode of this invention comprises a submic­
ron metal cylinder acting as a potential well for an energetic 
electron with an assymetric tunnel junction at one end and 
reflecting step at the other end. The energetic electron is 
produced by the absorption in the metal cylinder of an 
energy quanta ν such as a photon in the visible light range. 
The energetic electron travels back and forth without colli­
sion or energy loss in its own conduction band within the 
potential well until it passes through the junction; whereup­
on its kinetic energy is converted to electrical potential 
energy at a greater voltage on the other side of the junction. 
This forward current is proportional to the input rate of 
energy quanta; but the reverse current is limited by a tunnel 
junction comprising new and novel materials and dimen­
sions. A first terminal is attached to the metal cylinder to 
provide electrons to replace those which pass through the 
junction; and a second terminal is attached to the metal on 
the other side of the junction. The Femto Diode of this device 
has applications in diverse fields such as light to electric 
power conversion, an electric power to light laser, high-­
speed computers and communications which are disclosed.

Title: Internal-combustion engine with at least two adjacent liquid-cooled cylinders
IPC: F02F1/10
Filed: 1986-03-27
Abstract: Each cylinder of a liquid cooled in-line internal combustion engine includes a cylinder pipe surrounded by an annular cooling chamber. The cooling chambers are interconnected in series by crossover passages between adjacent cylinder pipes and the cooling chambers have a greater cross sectional flow area on one side of the longitudinal central plane of the engine than on the other side. This cross sectional flow area relationship is reversed from cylinder to cylinder to thereby cause a meandering course of flow for a portion of the coolant thereby assuring adequate flow around the entire surface of the cylinder pipe and good flushing of the crossover passages between the cylinder pipes.

Abstract: A wire rope tester which can detect broken wires, area reductions, or wire contact irregularities. The tester includes two permanent magnetic stacks (32 to 38) which produce axial adjacent and opposed DC magnetic fields which magnetise the rope (46).

Patent EP-0232240-A3 (EP)
IPC: G07C9/23
Filed: 1987-02-06
Abstract: The invention relates to a method for establishing 
whether or not a first person who has identified himself for 
entrance to a confined space or area with the aid of a mag­
netic card inserted in a card reader (7) shall be granted free 
passage to the confined area through a door, gate or like ent­
rance. The card reader (7) evaluates a code significant to the 
magnetic card and, through the intermediary of electric and/­
or electronic circuits compares the code with a plurality of 
pre-stored codes (12) and causes a signal to be generated for 
deactivating a circuit (2) for latching the door, gate or like 
entrance when, and only when, acceptable agreement is 
found between the sensed magnetic card code and the pre­
stored codes, to therewith afford free passage to said person. 
The method is mainly characterized in that:  
a) A second person responsible for monitoring the per­
sons desiring entrance to the confined space or area activates 
(6) means (16) incorporated in the electric and/or electronic 
circuit so that a code significant of a magnetic card subsequ­
ently sensed in the card reader (7) can be stored among a 
number of pre-stored codes (12);  
b) The second person identifies the first person and es­
tablishes the validity of a magnetic card in the possession of 
the first person, the magnetic card being intended for other 
main purposes than that of obtaining entrance to the con­
fined space or area;  
c) The magnetic card belonging to the first person is in­
serted into the card reader (7) which senses the code signifi­
cant to the card;  
d) The significant code is therewith stored as an addi­
tional code among pre-stored codes (12), and in that  
e) a subsequent sensing of the magnetic card in the card 
reader (7) affords free access to the confined space or area.
