Patent EP-0356074-A3 (EP)
Title: Dock leveler
IPC: B65G69/28
Filed: 1989-08-10
Abstract: A hold-down device for a mechanical dock leveler 
which is spring loaded so that when the hold-down 
device is released the deck (22) will rise and the lip (24) 
will extend. When the deck (22) is walked down, the 
hold-down device maintains the deck in contact with 
the truck bed (16). This is accomplished by means of the 
interaction and geometry between a brake actuating 
arm (40) and a brake release arm and the associated pins. 
As the dock leveler is lowered, the perpendicular 
distance from an anchor pin to the center line of a 
slot (48) in the brake actuating arm (40) increases. This 
causes the brake actuating arm (40) to move upward in­
creasing tension on the brake band (39). The brake re­
lease arm moves and increases the braking force. As 
the dock leveler is raised the braking force is re­
duced. The leveler includes a two-stage safety leg (82,84) 
with a guide bar (86,88) attached to the safety leg stop (92). 
The guide bar (86,88) limits free travel of the safety leg (82,84). 
The guide bar engages projecting tabs from each stage 
of the safety leg to require upward or free movement 
above a respective engagement position before the 
safety leg can move forward and re-engage the stop.

is intended for use in commercial establishments such as 
cafés, petrol filling stations or railway stations and is 
capable of occupying a stand-by mode pending insertion of 
a food item into the oven cavity (10). During the stand-­
by mode the electrical resistance heating means are 
energised at a lower power level (continuously or in 
pulses) in order to provide a reservoir of heat which 
speeds the cooking process. The oven is capable of 
occupying the stand-by mode continuously.

Patent EP-0394866-A3 (EP)
IPC: G02B5/18
Filed: 1990-04-20
Abstract: Alignment difficulties in optical computing arrangements are overcome 
by integrating the optical components on a single substrate and arranging the 
elements in a manner that causes them to interact with one another to perform the 
desired function. The substrate has one or two major surfaces and the elements are 
grown or fabricated on those surfaces using conventional integrated circuit 
manufacturing techniques. Recognizing that an optical circuit can be larger than 
what can be fabricated on a single substrate, aligning structures are fabricated onto 
substrates that need to be coupled to form the optical circuit. The aligning structures 
contain registrable protrusion and indentation portions, such as ridges and grooves, 
that are imbedded into the substrates as part of the manufacturing process of the 
optical elements. Most advantageously, the position-sensitive optical devices are 
manufactured on one side.

Patent EP-0433979-A3 (EP)
Title: Fault-tolerant computer system with/config filesystem
IPC: G06F11/07
Filed: 1990-12-18
Abstract: A computer system in a fault-tolerant configuration employs multiple identical CPUs executing the same instruction stream, with multiple, identical memory modules in the address space of the CPUs storing duplicates of the same data. The system detects faults in the CPUs and memory modules, and places a faulty unit offline while continuing to operate using the good units. The faulty unit can be replaced and reintegrated into the system without shutdown. The computer system employs a power supply system including a battery backup so that upon AC power failure the system can execute an orderly shutdown, saving state to disk. A restart procedure restores the state existing at the time of power failure if the AC power has been restored by the time the shutdown is completed. The system employs a pseudo-filesystem to dynamically manage the hardware components. A directory which appears as a standard, hierarchical directory in this filesystem contains a file for each component; each file maps to either a hardware component or a software module. The pseudo-filesystem hierarchy is determined during system initialization and is automatically updated whenever the software or hardware configuration changes. The pseudo-filesystem, called /config filesystem herein, is implemented as a Unix filesystem in the Unix filesystem switch. The multiple CPUs are loosely synchronized, as by detecting events such as memory references and stalling any CPU ahead of others until all execute the function simultaneously; interrupts can be synchronized by ensuring that all CPUs implement the interrupt at the same point in their instruction stream. Memory references via the separate CPU-to-memory busses are voted at the three separate ports of each of the memory modules. I/O functions are implemented using two identical I/O busses, each of which is separately coupled to only one of the memory modules. A number of I/O processors are coupled to both I/O busses. I/O devices are accessed through a pair of identical (redundant) I/O processors, but only one is designated to actively control a given device; in case of failure of one I/O processor, however, an I/O device can be accessed by the other one without system shutdown. <IMAGE>

Title: Remote interrupt processing
IPC: H04L29/00
Filed: 1990-05-15
Abstract: A local application (10) connected to a remote application (18) 
over a computer network (16,30) can interrupt processing of the remote 
application. To do so, a new communications link is opened (30), and an 
identifier of the remote process to be interrupted is passed to the 
remote node. The new communications link is then closed. A manager 
process (34) on the remote node raises the interrupt to the desired 
remote application, which returns acknowledgement of the interrupt over 
the original connection.

Title: Catalyst for polymerization of olefins
IPC: C08F4/16
Filed: 1991-01-16
Abstract: The present invention concerns a catalyst for polymerization of olefins, said catalyst comprising an inorganic support material with catalytically active chromium and titanium compounds bound on its surface. The catalyst is prepared according to the invention by bringing the catalytically active metal compounds sequentially in vapour phase onto the support material surface in excess amounts in relation to the binding sites available on the support material surface. The support material temperature is maintained above the condensation temperature of the vapour, preferably above 160 DEG C, and simultaneously sufficiently high so as to achieve the thermal activation energy necessary for the generation of bonds between the support material and the catalytically active material or its compound. To avoid desorption of the chemisorbed compounds, the temperature is kept below approx. 500 DEG C. The activity of a catalyst in accordance with the invention even with very low contents of the catalytic metals is as high as the activity of a catalyst of multiply higher metal contents that has been prepared by the methods of the conventional technology.
