Patent EP-0246857-A3 (EP)
IPC: F16B2/06
Filed: 1987-05-19
Abstract: There is disclosed a clamping device (15) for holding-­
down a grid-like support member (10) on an underlying 
flanged support beam (12a), the device being taken in use 
from the side of the member (10) which is remote from the 
beam (12a) and partly through a space (13) defined between 
two generally parallel elongate elements (11) of the member 
(10), and being manipulatable so as to bring the device 
into gripping engagement with a flange (12) of the support 
beam, and the device comprising:  
    a saddle portion (16) which is shaped so as to be 
capable of being non-rotatably seated on said elements (11) 
at said one side of the member (10), a clamping portion 
(17) which is engageable with one side of the flange (12) 
of the support beam which is remote from the grid-like 
member (10), and a threaded fastener (18) which 
interconnects the saddle portion (16) and the clamping 
portion (17) and which is operable relatively to draw the 
portions (16, 17) towards each other in order to clamp the 
grid-like member (10) to the support beam (12a).
Patent EP-0254438-A3 (EP)
IPC: G06T13/80
Filed: 1987-06-30
Abstract: In a computerized simulation system, the 
behavior of a model comprising a group of 
interrelated objects in an object oriented 
programing environment is defined by a constraint 
network including temporal constraints, which the 
future behavior of the model must satisfy following 
triggering events. Following a triggering event, 
time stamped representations of messages are 
created and stored in a queue. The value of a time 
variable representing time is progressively 
incremented and the message indicated by each 
enqueued representation is sent to the model as the 
value of the time variable surpasses the value of 
the time stamp of the representation. The message 
representations and the value of their time stamps 
are created according to the requirements of the 
constraint network such that the messages cause the 
model to perform the appropriate actions at the 
appropriate times in order to satisfy the temporal 
constraints defined by the constraint network.

Patent EP-0278528-A3 (EP)
IPC: G06T11/40
Filed: 1988-02-15
Abstract: A system for searching a predetermined boundary of a 
closed pattern comprises a memory for storing data of a 
given closed pattern, and a reading unit for sequentially 
reading each pair of vertically adjacent words of each pair 
of vertically adjacent lines of the given closed pattern 
from the memory in the same reading direction. A search 
unit receives the pair of vertically adjacent words from 
the reading unit for searching a boundary in each of the 
pair of vertically adjacent words and for generating data 
indicative of a position of a found boundary for each of 
the pair of vertically adjacent words. A comparison unit 
receives the boundary position data of the each pair of 
vertically adjacent words so as to judge in which of the 
vertically adjacent words the boundary is found earlier 
than the other. A processing unit coupled to the 
comparison unit determines whether or not the found 
boundary is the predetermined boundary.

Patent EP-0311886-A3 (EP)
Title: Frame for building covers for ground openings
IPC: E02D29/14
Filed: 1988-10-05
Abstract: At their ends, the frame parts (2) of the frame have connecting lugs (4, 5) which are arranged at a different height. During assembly of the frame, two frame parts (2) lie next to one another, the connecting lugs (4, 5) of which lie one above the other at a distance apart and are connected to one another by a screw connection (13). So that the frame parts (2) are connected to one another in a positive-locking manner, the frame is turned upside down and a liquid, pasty or granulated filling material is poured into a recess on the underside of the higher connecting lug (5). The filling material also flows into the bore (6) for the screw connection (13), which bore (6) is covered by a washer (16). After the filling material has solidified, the frame can be transported either in this state or in the dismantled state and put together again in the same manner. Due to this type of assembly, mechanical working of the frame parts 2 can be dispensed with.

Title: Impact printer print mechanism and method of manufacture
IPC: B41J9/133
Filed: 1989-06-22
Abstract: Electromagnets (54) and spring-damper units (34) respectively 
impart forward movement and rearward movement to slider 
members (26, 26') having hammer faces (30) at their forward ends and 
armatures (32) intermediate their lengths. The electromagnets (54) 
and spring-damper (34) units are mounted by the frame of the 
print mechanism for independent longitudinal adjustive 
movement. Adjustive movement of the spring-damper 
assemblies (34) effects lateral alignment of the hammer faces (30) at 
the forward ends of the sliders (26, 26'). Adjustive movement of the 
electromagnets (54) effects adjustment of the forward movement 
characteristics of the sliders (26, 26'). Clamping forces are 
preferably imposed upon the electromagnets (54) pending and 
during their adjustive movement. Anchoring of the 
electromagnets (54) in their final positions preferably is 
accomplished by laser welding. An inexpensive frame plate (14) 
restrains lateral movement of the sliders, maintains desired 
spacing between the pole faces (62) of confronting 
electromagnets (54), and provides a surface upon which adjustive 
movement of the electromagnets can readily occur.

Abstract: The two-stage reverse flame thermocombustor is consisting of four shells (1,2,3,4,) forming four chambers (A,B,C,D) of which the upper chamber (A) is acting as a storage space for fuel mixed with limestone. The second chamber (B) surrounding the first chamber, preheats the precombustion air,the flow rate of which is regulated by a fan (8). The third chamber 3, located below the first, is closed at its bottom end by a rotary disc (11) for elimination of the ashes and solid residues. The first combustion stage of the fuel and limestone takes place in this third chamber (C). The combustion gases enter the fourth chamber (D) through radial slots (13) where more air is added through a ring-shaped bustle main (33) and nozzles (15) for final combustion at high temperature. Combustion gases are conveyed to the users through the duct (16).
