Abstract: The compounds represented by the general formula <CHEM> wherein R is an alkyl group having 1-10 carbon atoms are novel compounds which have not been reported in the literature. Since they have excellent affinities for tissues with particular high corneal permeability and show anticataract activity at low concentration, the compounds are of value as prophylactic and therapeutic agents for cataract.

Abstract: For synchronizing a data block in a receiver, there are transmitted consecutively and prior to the data block: a first bit sequence of alternating "0" and "1" levels for determining the bit clock and a second bit sequence for determining the block synchronization by correlation. In known methods of determining the bit clock, the phase range of the individual bits of the received digital signal is divided into sub-intervals and the phase position of the bit clock is determined on account of the number of edges in these sub-intervals. In order to avoid fading and phase jitter having a detrimental effect on the bit synchronism, more specifically when transmitting through radio transmission links, N-phase-shifted clocks having the same clock frequency are generated in the receiver by means of which the first bit sequence is sampled. The clock for which the number of sample-value changes of the first bit sequence is established as having a predeterminable minimum value during a predeterminable time-interval is utilized as the phase synchronous bit clock.

Abstract: A system is described for stimulating a nerve or a muscle fibre of a living body, e.g. a hearing nerve in the cochlea. The system comprises an implant (28) and an electrode (35) for stimulating the nerve or the fibre, which electrode is connected with the implant. To supply electrical power to the implant, a small sized transformer is used, of which one coil (26) is implanted into the body and the other is outside the body but in the vicinity of the implanted coil. In case of the ear, the implanted coil is around the auditory duct and the outer coil is inserted into the duct, so that both coils are substantially coaxial. For supplying information to the implant, infrared transmission through the skin is used, wherein the transmitter (39) is provided adjacent to the skin on the outside and the receiver, possibly forming a part of the implant is located on the inside of the skin and adjacent thereto.

Abstract: The bath consists of an infrared light source (Q), which is equipped with preferably rod-shaped infrared emitters (S). A first reflector (R1) of parabolic form effects an irradiation which impinges approximately vertically on the area of the body facing towards the infrared light source (Q). Further reflectors (R2, R3) provide for as uniform as possible an irradiation from the side. This arrangement ensures that at least 50%, but at most 90%, of the body surface of the user is irradiated. So that the intensity of radiation is so great that sweating occurs but there is no unpleasant heat sensation, a control which can be activated by the user is preferably provided. An IR-B and an IR-C filter block that fraction of the IR radiation which would cause an increase in the temperature of the interior of the body. A further filter blocks the visible region of the radiation spectrum to the extent that only bright-orange light is visible. The IR radiation can be readily supplemented with UV radiation. <IMAGE>

Abstract: A false ceiling structure including parallel carrying sections curved in a vertical direction, which carry false ceiling slabs (3), the latter being self-supporting between adjacent sections (1). The slab (3) has a readily flexible outer layer (32) which is exposed. The slab further includes a mineral fibre layer (33) which is bonded to the outer layer (32). The layer (33) is formed of a plurality of parallel, tightly adjacent billets (331) of mineral fibre. The billets extend unbroken between the two slab edges (31) carried by the section flanges (2). The billets have a fibre orientation, which is in planes substantially at right angle to the plane of the outer layer (32) and to the longitudinal direction of said two slab edges (31), such that the slab (3) has a substantially lower bending stiffness in the longitudinal direction of the sections (1) then at right angles to said direction.

Abstract: An obstetrics cushion (10) made of foam or similar material allows early, comfortable adoption of a supported squatting position during labour. A relatively thin bridge portion (12) allows vertical compression while the larger thigh pads (14, 16) support most of the weight. The resultant leverage of the femora on the hip joints increases the dimensions of the pelvic outlet. Pulling on the side handles (30) during labour allows the maternal pushing efforts to be better co-ordinated and directed downwards in the direction of the birth canal. The cushion (10) is shaped so that it is easily fitted against the raised end of a delivery bed or a foam wedge. The height and shape of the cushion (10) allows good access for birth attendants to conduct the delivery in the desired upright position.

Abstract: The means enables a signal transmitted by the clock to be interrupted or else finally turned off by the user approaching the clock, or else moving only a part of his body, for example his hand towards it. The clock is preferably equipped with a transmitter 2, 2' emitting infrared radiation or ultrasonic waves and a corresponding receiver 3, 3' which detects infrared radiation or the ultrasonic waves reflected by the moved body part 1. The temporal change in intensity is determined in a signal-conditioning circuit 4, 5 and 6 and compared in a threshold switching stage 7 to a prescribable value upon the overshooting of which the alarm signal A is turned off.

Title: Echo canceller
IPC: H04B3/23
Filed: 1988-07-26
Granted: 1992-09-30
Abstract: The step width with which a transversal filter (21) in the echo canceller (10) is set is also dependent on the size of the error signal (F) at the transmission path output (13). As a result, when a large signal (F) occurs, the echo canceller (10) quickly compensates with a large step width for the echo which causes the greatest interference and subsequently, when a smaller error signal (F) occurs, effectively cancels the residual echo with a smaller step width. In the case of duplex operation which cannot be reliably identified, a large signal is simulated. The aim is to prevent this effect. An echo measuring device (26) identifies duplex operation with relative reliability and sends a step width setting signal (S) to the transversal filter (21). A frame adaptation memory (28) detects a phase shift or slip and then resets the echo measuring device (26) with a reset signal (R). The echo canceller is used in international gateway exchanges. <IMAGE>

Abstract: Machine for high speed folding in accordion-like manner bands (102) of elastic materials such as paper, thin plastic laminates or metal sheets coming from coils on which they are stored in a rolled up form, coprising an orientable guide (104) launching said band (102) against an obstacle (24, 26) so as to cause a length of said band (102) to be bent in arc-shaped manner, thus forming a loop (150), towards a first roller (20) having circumferential grooves (40) and areas (136, 138, 140) having high friction coefficient with respect to the material of the band (102) to be folded, said roller (20) being rotated at a speed such that its peripheral speed is greater than the advancing rate of said band (102), whereby the loop (150) formed by said band (102) is drawn by said roller (20) up to impinge against relieves (32) engaged within said circumferential grooves (40), causing said band (102) to be pinched, thus forming a sharp fold and then to start again the arc shaped folding in the opposite direction until it comes into contact with said loop (150) a second roller (22), fully identical to the first one (20), whereby the band (102) is pinched between said roller (22) and corresponding relieves (36) engaged in circumferential grooves thereof (44), the band (102) being thus sharply folded again and returned towards said first roller (20), and so on, whereby an accordion folded package of band (166) is formed up to the desired size.
