Patent EP-0463682-A1 (EP)
Inventor: VOORMAN JOHANNES OTTO
IPC: H03K3/286
Filed: 1991-06-18
Abstract: Latch circuit comprising a differential amplifier T1, T2 for amplifying a data signal D, ND to be latched, applied to the inputs 1, 2 of the differential amplifier, a flip-flop T3, T7, T4, T8 for latching the amplified data signal across the load impedances 6, 7 which are connected to the transistors T1, T2 through switching transistors T5 and T6 if the clock signal CLK is high and are detached therefrom if the clock signal is low. When there is a high clock signal the emitter junctions 11, 14 of the flip-flop are currentless. Because the transistors T5 and T6 fix the voltage at these junctions, it is avoided that the voltage flows away there. Consequently, it is achieved that the decision accuracy of the latching operation is retained also with high clock signal frequencies.

Abstract: An insert (50) is provided to be attached to a shield (24) on a surgical trocar obturator handle (30). The insert is actuated by the surgical trocar cannula handle (30) so that it causes the shield to expose the sharpened obturator tip after insertion of the obturator and shield within the cannula. After usage, the insert is deactivated so that the shield again covers the obturator. The obturator can then be removed from the cannula handle and obturator shield, and the obturator handle can be discarded safely.

Abstract: For a predetermined period (2s) following application of a closure command (5), the semiconductor (T1) of the static power switch, supplied with DC voltage (V1), is controlled by a regulating circuit (F, 8, R3) so as to operate as a current generator limiting the current to a value (100 mA) much lower than its nominal value (30A). A fuse (F) serves as measuring shunt. The switch can include a circuit-breaker function. In this case, the circuit for fault detection (13) measures the voltage across the terminals of the semiconductor (T1) and provides an opening signal when this voltage exceeds a predetermined threshold.

Abstract: The present invention relates to a double-coating cup for coating an optical fibre with two protective layers simultaneously. The cup includes a body provided with an axially extending, frusto-conical boring whose largest diameter is located on the fibre-inlet side, a die holder firmly pressed into the body and having a frusto-conical outer surface which corresponds to the boring, and two die nozzles inserted in the die holder and functioning to apply the two layers of coating material. According to the invention, the body (1) has two first diametrically opposed first coating-material inlet channels (4) spaced at a first axial distance from the inlet side, and two second diametrically opposed second coating-material inlet channels (5) spaced at a second axial distance from the inlet side. The die holder (8) has a frusto-conical boring (10) whose largest diameter lies on the fibre inlet-side, a first cylindrical boring (11) which is a continuation of the conical boring, a first shoulder (12), a second cylindrical boring (13), a second shoulder (14), and a third cylindrical boring (15), wherein the outer surface (9) of the die holder has first ring-shaped slots (17) and first radial borings (18) which connect with the ring-shaped slots (17) and which open into the junction between the frusto-conical boring (10) and the first cylindrical boring (11), and second ring-shaped slots (19) which connect with second radial borings (20) which open into the second cylindrical boring (13). A guide die (21) is inserted into the conical boring (10) of the die holder and includes an outwardly extending part (25) in the end-wall (26) of the die. A first cylindrical die nozzle (27) having a frusto-conical recess (28) is inserted in the first cylindrical boring (11) in a manner such as to form a first coating-material gap or slot (30) between the die nozzle (27) and the guide die (21). A cylindrical intermediate guide die (34) is inserted against the first shoulder (12) and has a frusto-conical outwardly projecting part (37) in the end-wall (38) of the die. A second cylindrical die nozzle (39) having a frusto-conical recess (40) is positioned in the second cylindrical boring (13) and in abutment with the second shoulder (14) in a manner such as to form a second coating-material gap or slot (43) between the die nozzle (39) and the intermediate guide die (34). The die nozzle has distribution channels (44) which connect with the second radial borings (20) and which distribute coating material around the fibre coated with the first coating material and therewith centre the fibre in respective dies.

Title: Process for transmitting digital data, in particular sound data, in a tv channel.
Inventor: DINSEL SIEGFRIED
IPC: H04N7/06
Filed: 1990-12-11
Abstract: In a method of transmitting digitally coded information in a television sound channel, the digitally coded information is inserted on an existing frequency-modulated RF sound carrier as a channel-coded signal above the television audio-frequency base spectrum in the base band. The modulation amplitude is selected so that disturbances during reproduction of the television sound are excluded in the receiver. The spectrum of the channel-coded signal is evenly distributed over the available frequency range using a pseudo-signal during modulation intervals. The clock frequency of the channel-coded signal is coupled with the line frequency.

Abstract: The present invention relates to a process for obtaining agar-agar that can be dissolved quickly in water at a temperature higher than its gelling temperature. It consists of using the classical agar-agar in the form of dried powder or dehydrated agar gel granules obtained after the operation of mechanical pressing or of freeze-thawing, and of passing it through a single-screw or twin-screw extruder. The process can be carried out in mixture with principally water and other products such as the locust bean gum, the guar gum, sugar, peptones or dispersants like the metarine, fatty acids or organic silicones. 
Such process allows to produce, at a reduced price, an agar-agar with properties of instantaneous dissolution in hot water at a temperature higher than its gelling temperature.
