Title: Frequency multiplexing transmission system for satellite - selects mixing frequency signals so that frequency bands overlap by one channel
IPC: H04J1/04
Filed: 1990-05-30
Granted: 1991-12-19
Abstract: In the transmission system described, L channel signals, using frequency multiplexing, are received, filtered and, finally in a multiplication process using N different mixing frequency signals, are separated in N channel groups for each of the Ln channels into a basic band. The analogue signals involved are subjected to an anti-aliasing process in the filters (F1...FN) and then converted into digital signals. In the N part-demultiplexers (D1...DN) following, the Ln' (greater than Ln) channels can be demultiplexed. The frequency (f1...fN) of the mixing frequency signals is selected so that the frequency bands of two adjacent channel groups overlap by the bandwidth of one or more channels. USE/ADVANTAGE - Improved in reliability of transmission. It is suitable for communications systems.

Title: Motor vehicle door closure with memory for opening operation indicates initiated but not completed opening of a door or boot lid
Inventor: BRACKMANN HORST
IPC: E05B65/12
Filed: 1990-10-19
Granted: 1999-10-21
Abstract: The arrangement has a lock case (1), rotary catch (2), locking pawl (3) and triggering lever (8).  The triggering lever is associated with a memory lever (6) with a contact surface that contacts the triggering lever under the influence of a spring with the door closed. The triggering lever is raised from the contact surface for a sufficient triggering actuation and the memory lever pivots by spring force so that both levers engage a blocking surface and hold it in the triggering position, in which the pawl is held by the triggering lever. The memory lever is returned to its initial position if the door has previously opened and releases the pawl. A switch indicates the memory position of the memory lever, which is pivotably mounted between the rotary catch and switching lever.

Title: Increasing flexibility and strength of nonwoven material - by using bi-component tapes mechanically sepd. into fibres comprising fibrils which are enveloped by polymer matrix, etc.
IPC: D06M23/00
Filed: 1991-10-14
Granted: 1992-11-05
Abstract: Increasing the flexibility and strength of a nonwoven comprises using a flat fibre structure created by carding, needling and shrinking.

Abstract: FIELD: vehicles. SUBSTANCE: composition diaphragm has two layers. Each of them is produced by elements and joints between elements are displaced in layers. Number of elements in each layer varies in range of 12-24. Each element is shaped as sector part with inner rectangular part, shape and size of parts are given in invention specification. Each element is cut out from fabric so that angle between direction of longitudinal axis of element and fabric warp is constant. Optimal angle is 45 ± 7.5 degrees. When elements are laid down in two layers in opposite to one another, they are impregnated with binder and polymerized in autoclave. When elements are being laid down, their rectangular parts are superimposed. This results in increased diaphragm thickness near hub. When wheel is assembled, diaphragm face surface is shaped convex by means of pinching its peripheral edge and stretching it by point force applied against center of diaphragm circumference. This method of diaphragm manufacturing results in possibility to escape production of wave-like wrinkles in tangent direction, in other words this prevents local loss of stability. EFFECT: increased rigidity, increased service life, increased reliability. 2 cl, 5 dwg

Abstract: FIELD: agricultural engineering. SUBSTANCE: device has teat cups 1 and 2 for the front and rear udder lobes respectively, claw 6, and milk can 7. A vertical partition divides the can into chambers 9 and 10. Movable claw bottom 13 is provided with handle 32. Milk chamber 9 of the claw is in communication with air- operated member 24, and chamber 10 communicates with air-operated member 25. Part 18 of receiver 16 is open to air-operated member 24 and claw 6 via vacuum valve 29, and part 19 is open to air-operated member 25 and claw 6 via vacuum valve 29. Flexible ties 22 and 23 are provided with telescopic inserts. As the animal walks, expansion of air-operated members 24 and 25 followed by their contraction resulted in deeper vacuum in both parts 18 and 19 of the receiver. The animal comes to a halt, and the teat cups are put on the teats. Owing to vacuum under the teats they are squeezed from their bases to tips, and milk is taken as if it was sucked out by a calf. The rear upper lobes are "resting" while the front ones are in the suction phase, and vice versa. EFFECT: higher efficiency and convenience in operation. 7 cl, 2 dwg
