Patent EP-4236176-A3 (EP)
Inventor: VERMANI SAMEER
IPC: H04B7/024
Filed: 2019-10-22
Abstract: This disclosure provides systems, methods, apparatus, and computer programs encoded on computer storage media, for relative timing drift correction for distributed multi-user transmissions. In one aspect, a first access point (AP) may receive a first signal from a second AP. The first signal may be associated with a channel sounding procedure to be performed substantially simultaneously by the second AP and the first AP. The first AP may then receive a second signal from the second AP, and prior to a substantially simultaneous transmission by the second AP and the first AP. The second signal may include timing information relative to the first signal. The first AP may determine a start time of the substantially simultaneous transmission at the first AP based on the timing information, and may initiate the substantially simultaneous transmission according to the determined start time.

Title: Process for colouring (printing) web-like items, particularly ski-coverings, and such articles
IPC: B41F17/00
Filed: 1980-12-06
Abstract: The invention refers to a process of coloring (printing) of track-like objects (2), especially ski coverings of thermoplastics, such as olefins, especially high and low pressure polyethylene where, the layer is brought continuously as a hot foil, essentially in a state of fusion, in contact with a print carrier (3), on which there has been deposited a print pattern first of sublimation type and then of diffusion type dye stuff. A transfer of the dye onto foil (2) occurs in a short time and only essentially along a small areal strip perpendicular to the common direction of conveying of layer (2) and print carrier (3). It is preferred that the transfer of dye occurs in the gap between rollers (5, 6) through which the foil and the print carrier are guided. This allows the obtainment of warpage-free print patterns on relatively thin-walled track-like objects in a continuous process, where it is assured that no warpages occur after cooling or reheating of the printed layer. Also, migration problems are avoided by means of short-term locally limited penetration under high pressure in the roller gap.

IPC: A61G7/005
Filed: 1980-01-03
Abstract: A hospital bed having a facility for tilting the mattress 
platform (16) to a foot-down configuration, the bed including 
a main frame (11) and a sub-frame (12) which carries the 
mattress platform (16), these being associated with each 
other (at 13) towards the foot end of the bed. Towards the 
head end of the bed, a member (22,23) is pivoted to the main 
frame (11) and the sub-frame (12) at separate spaced pivot 
points (24,25). The member can be moved by manual operat­
ing means such as a worm arrangement (27,28) to change the 
relative positions of the pivot points (24,25) thereby changing 
the angular relationship between the main frame (11) and the 
sub-frame (12) to enable a slight foot-down tilt to be achieved. 
The mechanism operates completely independently of any 
other facilities provided on the bed such as lifting and lower­
ing facilities, head-down tilt facilities or contoured mattress 
supports.

Patent EP-0087743-A3 (EP)
Title: Orbital speed reducer with compensation coupling
IPC: F16H1/48
Filed: 1983-02-23
Abstract: A speed reducer having an orbitally driven rotor, mounted for free rotation on a rotor drive wheel driven along a rotary path by a drive shaft, has a perimeter defined by an epitrochoidal curve that simultaneously engages each of a series of rollers arranged in a circle around the rotor, the number of lobes on the rotor being one less than the number of surrounding rollers. Rotation of the drive shaft causes the rotor to move orbitally and to rotate with a speed reduction equal to the reciprocal of the number of lobes.The rotor drive wheel is driven by a compensation coupler that prevents radial forces of the rotor and the rotor drive wheel, such as may be generated as a result of inaccuracies in machining, temperature changes, etc., from being transmitted to the drive shaft where they could be translated into large forces. With the present arrangement, the drive shaft provides only a rotary thrust on the rotor drive wheel and is shielded from reaction movements of the rotor and rotor drive wheel.The rotor drive wheel is driven along an orbital path by a variable-length crank arm that extends into a radial opening in the rotor drive wheel and makes sliding engagement with opposite faces of the radial opening. The driving surfaces that engage the faces of the radial opening form, in a plane perpendicular to the axis of the drive shaft, arcs of a circle equal in diameter to the width of the radial opening. The radial opening is long enough to permit the rotor drive wheel and the rotor to follow the requisite orbital path. The crank arm includes an expansion slot that divides it into two fingers that embrace opposite sides of the radial opening. For smaller units, the spring quality of the fingers is relied upon to maintain firm engagement between the fingers and the faces of the slot. In larger units, an adjustment screw permits changing the spacing between the fingers to precisely fit the width of the crank arm to the width of the radial opening. In either case, the only radial forces on the drive shaft are those generated by the torque of the drive shaft.

IPC: C08K5/3442
Filed: 1983-05-04
Abstract: Novel compounds have been discovered in which a bis 
compound of a polysubstituted 2-keto-1.4-diazacycloalkane 
("2KDZC") provides a bridge between diisocyanate groups 
so as to form an oligomeric 2KDZC-urethane ("2K-U" 
oligomer) having from 2 to about 15 repeating units. The bis 
compound bridge itself consists essentially of two distally 
linked polysubstituted 2KDZC moieties, and the 2K-U oli­
gomer formed consists essentially of two 2KDZC moieties 
linked through their N¹ atoms, which moieties in turn are 
distally linked to urethane groups through the N⁴ atoms of 
the 2KDZC. Such 2K-U oligomers unexpectedly contain a 
self-limiting number of 2K-U repeating units which happens 
to provide 2K-U oligomers which are desirable and highly 
effective u-v light stabilizers in organic materials. More 
specifically, this invention provides a novel class of polymer­
ic hindered amine-urethane derivatives. particularly piperazi­
none bis compounds which may be distally linked to each 
other in a single step reaction utilizing an appropriately 
substituted diamine, a haloform such as bromoform or 
chloroform, in one of several known syntheses for making 
2-keto-diazacycloalkanones, some of which syntheses may 
preferably utilize a phase transfer catalyst. This bis com­
pound may then be hydroxyalkylated and reacted with an 
appropriate diisocyanate.

Title: Inductive measuring system or sensor arrangement, and its application
IPC: G01D5/22
Filed: 1983-05-06
Abstract: The invention includes a measuring arrangement and an inductive sensor arrangement with a transmitter coil which is fed by an RF oscillator, and a receiver coil in which an alternating field is induced by the transmitter coil. Transmitter coil and/or receiver coil are subdivided into at least two part-windings which are connected in opposition to one another in such a manner that the induced part-voltages at least partially cancel. The part-windings are arranged with respect to a metallic object in such a manner that when the position changes in at least one direction, the relative position of each individual part-winding with respect to the object changes differently. This results in a different influence on the inductances of the two part-windings with corresponding change in phase angle and output voltage. The relative distance of each part-winding from the object is monitored by means of auxiliary sensors. If the respective distances deviate, the auxiliary sensors produce a compensation signal by means of which errors due to an inclined position of the object or offset object edges can be avoided. <IMAGE>
