Patent EP-0277005-A3 (EP)
IPC: G01J1/00
Filed: 1988-01-27
Abstract: An attenuated fiducial replica of the far field 
pattern of a high energy laser beam (15) is obtained by a 
system and method wherein a first fraction of an incident 
high energy beam is deflected from one reflective surface 
(13) of a holey plate (12) and the diffracted orders of the 
beam are transmitted from the holes (16) to a concave 
reflector (20), which reflects diffracted orders toward an 
opposite reflective surface of the holey plate. A zinc 
selenide partially reflective member (25) is disposed 
on-axis between the rear reflective surface (28) and the 
concave surface (21) for re-reflecting successive fraction­
al portions of the reflected beam a selected number of 
times to attenuate the beam converging upon a focal plane 
from an effective focal distance greater than the physical 
length of the optical system.

Title: Optical fiber tap utilizing reflector
IPC: H04B10/213
Filed: 1988-02-12
Abstract: A tap for withdrawing light from an intermediate portion of an optical fiber core by passing light through a side of the optical fiber comprises an optical coupler in contact with an outside surface of an optical fiber which is bent and disposed in a plane. A light reflector (41)  extending transverse to the plane deflects the withdrawn light (3) towards the end surface (5) of a light element (6) disposed completely outside the plane. A similar arrangement may be used to inject light to an intermediate portion of an optical fiber. The tap may be used as a read tap to withdraw light, or as a write tap to inject light in optical fiber networks.

automatically whether the tape is optically 
transmissive or opaque and to modify the counting 
scheme accordingly.

Patent EP-0392725-A3 (EP)
IPC: H01L29/78
Filed: 1990-04-03
Abstract: A process forming metal silicides with uniform resistivity in integrated 
circuits is disclosed. A layer of metal, such as titanium, is deposited over a silicon 
surface. The layer of metal is capped with a layer of titanium nitride or silicon 
nitride. The cap layer prevents intrusion of oxygen during a subsequent heating 
process. (The oxygen intrusion undesirably raises the resistivity of the silicide.) 
Furthermore, when Rapid Thermal Annealing is used for the heating, improved 
uniformity in silicide thickness is typically obtained. The cap layer may be later 
removed or may be retained in some circumstances to provide local interconnects.

Title: Waterborne external release agent, and molding process for vulcanization of tyres or other rubber articles
IPC: B29C33/58
Filed: 1992-06-02
Abstract: An aqueous external release agent for the production of tyres and of other rubber articles is described, which release agent contains 5 to 35% by weight of diatomaceous earth, 0.5 to 6% by weight of pyrogenic hydrophobic silicic acid, 0.1 to 2% by weight of non-ionic surfactant, 0.2 to 3% by weight of a binder, 0.1 to 3% by weight of colorant, 0 to 5% by weight of ethyl alcohol and the remainder water. Preferred binders are styrene/maleic acid or styrene/maleic anhydride copolymers and especially the ammonium salts thereof. These external release agents are used in processes for moulding and vulcanising tyres and other rubber articles, the release agent being sprayed onto the preform with the aid of air-atomisation pistols before moulding and vulcanisation are carried out. A very good release effect is thus obtained without the vulcanisation being impaired. Because only very small quantities of external release agent are required, cleaning of the compression mould and thus an interruption of the production process are necessary much more rarely than when using conventional external release agents.

Title: Congestion control in high speed networks
Inventor: COLE ROBERT G
IPC: H04L12/56
Filed: 1993-06-28
Abstract: Congestion control is implemented at the resources that actually suffer
from congestion and, moreover the congestion control is performed within the
network as well as at its access points. In a particular embodiment, congestion
control is continuously performed at each resource. Use of each resource is
controlled according to a head-of-the-line weighted round-robin service discipline
thereby assuring fairness and full use of bandwidth for all active channels. Also, in
order to control conditions of congestion, the queue of data elements waiting for
service at each resource is regulated by a global congestion indicator for the entire
queue. The data elements of each channel that are waiting for service are further
regulated in response to specific local congestion indicators that are individualized
for each channel. The global and local congestion indicators are used to guarantee
predetermined levels of service for each channel. The values employed for the
head-of-the-line weighted round-robin service discipline are developed as a function
of at least the contracted-for bandwidth for each channel. The developed values are
replicated for each resource subject to congestion control.
