Title: Local area system transport
IPC: H04L29/06
Filed: 1989-03-03
Abstract: A message transfer arrangement includes a 
client node and a server node interconnected by a data 
link. The client node sequentially receives requests 
from user applications and generates, in response to 
each request, command messages for transmission by said 
interface, each command message including a command and 
having a transmit slot identifier identifying the 
request in the sequence of requests received by said 
request receiver and a transmit sequence identifier 
identifying the command message in the sequence of 
command messages relating to the request. The selection 
of whether to transmit a command message related to one 
request or to a subsequent request is based on a 
received slot identifier and a received sequence 
identifier in a response message.  
     The server node receives command messages from, 
and transmits response messages to, the client node over 
the data link. It selectively executes the command 
contained in each command message and generates, in 
response thereto, a response message including a 
response slot identifier and response sequence 
identifier corresponding to the command slot identifier 
and command sequence identifier. The determination of 
whether to execute a command in a command message is 
based on the command slot identifier and command 
sequence identifier of the received command message 
received by interface and the command slot identifier and 
command sequence identifier of the command message 
containing the previously executed command.

Patent EP-0326510-A3 (EP)
Title: Method and apparatus for applying single or multicomponent materials
IPC: G01F5/00
Filed: 1989-01-23
Abstract: A method and apparatus for metering and pumping 
multicomponents of high and low viscosity materials and 
subsequently mixing and applying such mixture includes 
gear pumps (62, 64) for pumping each component. Each 
gear pump has gears (156, 162) operating in a gear 
housing (66) for receiving and pumping one of the 
components. The gear pumps are simultaneously driven at 
a predetermined speed and each gear pump is designed to 
pump a predetermined amount of its respective 
components, at the predetermined speed. Flexible hoses 
(42, 44) connect the pumps (62, 64) to an applicator 
(44). Check valves (96, 98) are used to maintain the 
pressure in these hoses when the pumps are in their at-rest 
position. The gear pumps (62, 64) may be driven at 
the same rotational speed but are designed to pump a 
predetermined amount of the different materials so that 
the ratio of materials can be precisely set.  
     Where a single fluid is pumped, a gear pump (62′, 
62″) is driven by a hydraulically driven torque motor 
(64′) or an electric motor (70″). The pump has a 
discharge connected by a hose (40′, 40″) to a dispenser 
(44′, 44″). A check valve (96′, 96″) is used to 
maintain the pressure in the hose when the pump is in 
its at-rest position. The gear pump need only be 
operated as necessary to maintain pressure in the hose. 
Precise metering of the fluid pumped is accomplished by 
controlling the operation of the gear pump.

Title: Mosfet input type bimos ic device
IPC: H01L21/8249
Filed: 1990-02-16
Abstract: A BiMOS integrated circuit device comprises a 
bipolar transistor and at least one MOSFET. The 
collector and emitter of the bipolar transistor are 
connected to a high potential source and a low potential 
source, respectively. The MOSFET has two gate electro­
des (122-1, 122-2), a source, and a drain. The source 
is connected to the high potential source, and the drain 
is the base of the bipolar transistor by a diffusion 
layer (200). The diffusion layer (200) is located 
between the gate electrodes (122-1, 122-2), and serves 
as both the base of the bipolar transistor and the drain 
of the MOSFET. Therefore, the MOSFET has a great 
channel width, and a large current can be supplied to 
the base of the bipolar transistor. In other words, the 
MOSFET has a great driving capability, and the bipolar 
transistor has a high amplification factor.

Title: Skylightstrip for roofs.
Inventor: STEINBRECHER FRIEDRICH RUDOLF
IPC: E04B7/12
Filed: 1994-05-06
Abstract: A skylight strip (1) for a roof (2) of an arcuate cross-section is arranged transversely with respect to the roof ridge and is formed by skylight panels (4) held in a frame (3). Said skylight strip (1) runs over the entire extent of the roof width or of the roof arc, with the result that its short sides or ends (5) help to form, or continue, the border (6) of the roof, as it were. The skylight panels (4) are configured, in the direction of the short dimension, that is to say in the direction of the roof ridge, with straight surface lines, that is to say they are not of an arched configuration, and are held, on the long borders, in a sealing clamping fit, with the result that heat movements are possible. A cutout, enclosed on all sides, within a roof, can thus be avoided because such a skylight strip (1) can be fitted between the borders of individual roof elements (13) in such a manner as to connect and span the same. <IMAGE>

Patent EP-0723819-A3 (EP)
Title: Protective coating on steel parts
Inventor: SANDUJA MOHAN L
IPC: B05D7/24
Filed: 1995-12-11
Abstract: This invention relates to the coating of steel parts with organic polymeric materials for resistance to
corrosion, abrasion, impact, salt solutions of high and low pH (both in liquid as well as vapor state)
and corrosive atmospheric gases under the environment of high relative humidity and ambient
conditions of temperature and pressure. To obtain secure and permanent adhesion of the coating
on the steel article a polymeric coating is formulated so as to achieve chemical grafting to the steel
face. This involves the use of monomers, prepolymers, catalyst and a graft initiator system. The
monomers are preferably polyfunctional and when applied onto a metallic substrate, react via graft
polymerization with the metal to form a polymerized layer coated onto the surface of the steel
substrate. The monomers and prepolymers are so selected that when polymerized onto steel the
coating has substantially zero moisture vapor-gas transmission rate and consequently acts as a
barrier to moisture, oxygen and other gases from coming in contact with the surface of the steel
substrate thereby improving the protective potential of the coating. Fillers may be included in the
coating material to enhance physical or wear characteristics. Other components that can be added
are slip agents, wetting agents, thixotropic promoters and adhesion promoters. This coating process
is particularly advantageous for use with steel parts used in the manufacture of cranes.
