Title: Scaffolding with connecting devices
IPC: E04G7/30
Filed: 1987-12-30
Abstract: The system includes vertical posts with apertured disks secured thereto at intervals, coupling heads, wedge-like keys, scaffold pipes, coupling head extensions, and tank-link heads. Each coupling head has a horizontal slot receiving an apertured disk when the head is pushed into mounted position thereon, and has top and bottom key-receiving openings above and below such slot. A wedge-like key extends down through the top key-receiving opening, through a disk aperture, then through the bottom key-receiving opening, fastening the coupling head to the disk. Coupling heads for horizontal scaffold pipes have extensions insertable into the pipes. Diagonal scaffold pipes have tang-link heads, whose tank has an aperture for a pivot provided on an associated coupling head. Conventionally, the disks, coupling heads and pipes are all made of steel, the disks of 9 mm thickness and 122 mm diameter. The disclosed lighter-weight version employs disks and scaffold pipes made not of steel, but of light metal such as aluminum. The coupling heads although still of steel are differently designed, employing a smaller volume of material and thus lighter in weight. The disks are of 10 mm thickness and 124 mm diameter, producing a 33% loadability increase. Numerous other dimensional and configurational modifications of the standard elements compensate for any structural strength inferiority compared to the standard elements, but the herein disclosed lighter-weight versions thereof remain compatible with, and can be freely intermixed with, the heavier-weight standard elements.
Patent EP-0259147-A3 (EP)
IPC: F21S8/00
Filed: 1987-09-02
Abstract: A night light assembly (10) which plugs into and is sup­
ported by an electrical wall outlet (11) whose orientation on the 
wall is either horizontal or vertical. The assembly, when switched 
on, produces low-level illumination and at the same time exudes 
an aromatic vapor. The assembly includes a reflector shell (17) 
having housed therein a low-wattage bulb (B). Attached to the open 
front of the shell is a frame (28) adapted to accommodate a removable 
window cartridge (35) having a transparent plate (36) whose rear face is 
covered by a thin pad (37) of light-permeable porous material impreg­
nated with a volatile aromatic liquid. The shell is vented, and 
as the air therein is heated and expanded by heat emanating from 
the bulb, a convection current is produced which flows across 
the pad to volatilize the liquid, thereby creating an aromatic 
vapor that is discharged through the vent. Adherable to the 
front face of the window plate is a translucent sheet (15) having a 
picture (16) thereon of an object possessing a characteristic odor, 
the fragrance of the aromatic vapor being thematically related 
thereto. The sheet is so adhered to the plate as to orient the 
picture thereon to conform to the existing orientation of the 
outlet into which the assembly is plugged.

Title: Process and apparatus for depositing of high ohmic resistance layers by cathodic sputtering
IPC: H01J37/34
Filed: 1988-03-04
Abstract: Electrically conductive target materials are atomised by means of a magnetron cathode, supplied with a direct voltage, in a vacuum and in a reactive atmosphere with continuous feeding of reaction gas. Between parallel planes of the target surface and the substrate, there is a screening device which is held at a potential which is either positive relative to the cathode potential or self-adjusting. To increase the process stability, the reaction gas is fed at the shortest possible distance from the target surface, but outside the circumferential line thereof, as viewed in plan. The distance "a" between the target surface and substrate surface is kept smaller than 60 mm, preferably between 40 and 50 mm. The distance "d" between the screening device surface facing the target and the substrate is selected to be smaller than half the distance "a".
Patent EP-0290032-A3 (EP)
Title: Dispenser box for the removal of tape-like packing such as bandaging material, in particular pre-proportioned sections, which are wound singly or in parallel on a reel
IPC: B65D85/672
Filed: 1988-05-06
Abstract: The dispenser box has a removal opening which is provided with a swivellable closure flap. In dispenser boxes of this type, it is disadvantageous that the closure flap projects from the housing wall for the respective removal of a section of the packing, with the result that dust and the like can enter the housing. In order to avoid this, provision is made for the height of the removal opening to be slightly greater than the thickness of the web-shaped packing and for the lower slotted longitudinal wall to form a continuous rest with its front edge for the closure flap which returns automatically to its closed position. <IMAGE>

Patent EP-0289072-A3 (EP)
IPC: G06F15/16
Filed: 1988-04-11
Abstract: A method and apparatus is described for establishing a 
global binary assertion in a multiprocessor environment. The local 
objects have a three-value status variable: -active, disquiet-, 
-passive, quiet-, and -passive, disquiet-. First 
all local objects are made active. During execution, a local variable 
may do a transition from active to -passive, 
quiet- and this is signalled to a global 
synchronizer (40) process. Thereafter, cross-­
requests from a non-local object may reactivate a quiet object to the 
state -passive, disquiet-. The synchronizer (40) process counts the 
transitions from active to -passive, quiet- and thus can detect when all 
objects are quiet. The local operations may represent a garbage 
collection system, wherein originally root items are colored grey and 
all other items white. In a marking phase (56), all grey items are 
successively accessed. After verifying any other item referred to by 
such grey item, and if white, discoloring it to grey, the original item 
is discolored to black. If locally no grey items are left, the local 
collector process (42) 
goes to the state -passive, quiet-. Cross-processor 
references may awake it to either verifying a locally correct black 
color, or discoloring a white item to grey and restarting the color 
verification when no grey items are left globally, the synchronizer has 
reached the ultimate count, and vice versa. Thereafter, white objects 
are treated as garbage.
