Patent EP-0105180-A3 (EP)
Title: Working-chair
IPC: A47C1/032
Filed: 1983-08-26
Abstract: An office chair including a seat portion, a backrest portion joined to the seat portion in an articulated or flexible fashion, and an underframe. The seat portion is articulatingly supported, in an area of a forward edge thereof, on a front bearing pipe and the backrest portion is supported approximately at a hip level through supporting levers on a horizontally extending supporting shaft disposed below the seat portion at a distance therefrom so that solely by shifting one's weight, the inclination of the backrest portion and seat portion can be varied. A locking mechanism, which may be conveniently manipulated from a sitting position and which does not impair the overall appearance of the chair is provided which includes a locking lever disposed in a space between the bearing pipe and the supporting shaft in a housing section of the underframe. The locking mechanism is operable by way of a transmission path from an operating lever arranged in close proximity below the forward edge of the seat portion.

Title: Magazine for belted ammunition
IPC: F41A9/79
Filed: 1984-08-22
Abstract: The ammunition container is subdivided by partition walls into individual compartments. Such containers must be structured in such a manner that a cartridge belt can be easily laterally withdrawn from the container at the top thereof. For this purpose there are provided partition walls which are formed by a stationary rigid partition wall portion and a pivotable spring-type or resilient partition wall portion. The two partition wall portions are interconnected by a resilient member, such as a spring plate or leaf. Furthermore, the distance between the spring plates or leaves and the base member or floor of the container continually increases from one partition wall to the next-following partition wall in the direction towards the discharge or outlet opening of the ammunition container.
Patent EP-0139254-A3 (EP)
IPC: G06F12/06
Filed: 1984-09-28
Abstract: A multi-microprocessor implemented data processing 
system (10) having a single cycle data transfer capability for 
its memory mapped peripheral devices (16) is described. A 
host of controlling microprocessor (12, 14) provides address 
and control signals for memory (24) accesses. In addition, it 
also determines that a peripheral (16) operation is desired. 
When this occurs, a command is sent to the selected 
peripheral and a memory cycle, fetch or store, for the data 
transfer is initiated. The address bus is provided with the 
memory address for the needed data and a special decode 
that indicates the unique nature of this memory access. Logic 
circuit means (28) are provided to detect the special decode 
and to intercept the data bus (22) at the appropriate point in 
the bus cycle in response thereto. The logic circuit means is 
adapted to then responsively apply the correct control 
signals to the peripheral (16) to enable the desired data 
transfer after the data bus has been intercepted.

IPC: F23J15/06
Filed: 1984-10-26
Abstract: Energy and water are recovered from flue gases by 
cooling them to a temperature sufficiently below the acid 
dew point temperature by contact with an aqueous stream 
so as to recover the sensible heat and to reduce the water 
content of the flue gases by about 50%. The water by which 
the aqueous stream is enriched is subsequently flashed off 
to cool the stream back to its original temperature and the 
water vapor is then compressed to generate a higher tem­
perature vapor stream which is condensed to recover the 
water and extract heat. The aqueous stream is continuously 
enriched with material such as calcium carbonate to control 
the pH sufficiently as to avoid substantial corrosion due to 
acidic gases removed from the flue gases and the aqueous 
stream is purged continuously or periodically to remove 
compounds such as chlorides, calcium sulphates, and fly 
ash solids picked up from the flue gases. The system may 
be operated in two stage fashion in which separate aqueous 
streams are employed to cool the flue gases in two serial 
stages.

sor therefor with the feedstock.

Abstract: A pneumatic vehicle tire made of rubber or rubber-like material and having a reinforcing carcass that is anchored in the beads by being looped around bead cores that are essentially inextensible and/or resistant to compression. The bead cores have an essentially round overall cross-sectional shape. To increase the bending resistance of the bead cores, each bead core has an inner region of steel or other material of similar high strength and rigidity. Each inner region has a cross-sectional shape that is characterized by a dimension, in the radial direction of the bead core, that is greater than its dimension in the axial direction. Each bead core also has an outer region, of lightweight material, that complements the inner region to provide the essentially round overall cross-sectional shape for the bead core.

Abstract: In a registration system for compensating for distortion of 
a test printed circuit board (12) relative to a stored reference 
in a printed circuit board inspection system fiducial marks on 
the test board are compared with fiducial marks on the stored 
reference to determine distortion of the test board with respect 
to the reference board. This information is utilized to load a 
memory (18d) so that exposure (EXP) pulses for a scanning 
CCD camera (11) can be read out at intervals which com­
pensate for distortion in the scanning direction x. The fiducial 
information is also used to generate a pixel gate on the oc­
currence of each exposure (EXP) pulse to compensate for 
distortion in the y-direction. The exposure (EXP) pulses are 
further utilized to generate addresses to a buffer memory (19) 
storing the reference to cause patches representative of the 
reference board to be read out of memory in registration with 
patches representative of the couterpart surface location of 
the test board (12) to permit accurate real time comparison of 
the test board (12) with the stored reference.

Abstract: An apparatus for automatic inspection of printed circuit board assemblies inspects for the correct presence, positioning, and orientation of component parts mounted on a base printed circuit board. In this method for inspection of printed circuit board assemblies, an arithmetic comparison operation is conducted on several color pictures of different colors taken of the base printed circuit board mounted with the component parts; and a distinction is made between parts of the base printed circuit board not occupied by the component parts, and the component parts. Optionally, one of the base printed circuit board and the component parts is tinted in a color of a category selected from the group consisting of the green category, the red category, and the yellow category. The arithmetic comparison operation may be division, or may be subtraction. The base printed circuit board may be coated with a preflux mixed with a fluorescent agent, which may be green; or may be coated with a bonding agent mixed with a fluorescent agent, which again may be green. Illumination may be provided by a light source whose wave length varies from visible blue to ultraviolet. The color pictures may be taken by a color TV camera.

Title: Method for controlling automatic cable cranes and hydraulic control system
IPC: B66C13/18
Filed: 1987-04-08
Abstract: In known automatic cable cranes it is considered to be a disadvantage that, from the safety point of view, vibratory movements of the load pendulum, which can lead to inadvertent clearing of the automatic cable crane, could not be eased by constructional measures. On the other hand, the hydraulic valve layout is made in such a way that sudden displacements of the valves are normally necessary and two-way valves are used as slide or shuttle valves. The leakage losses which are consequently present, in particular in the zero position, can cause dangerous operating states. To avoid these disadvantages, the invention proposes to design the requisite main valves as separate individual valves with dead-time actuation and, in addition, to provide a delay time or a delay displacement so that undesirable vibratory movements of the load pendulum cannot lead to clearing of the automatic cable crane. <IMAGE>
