Abstract: On its seat plate (16), a bath insert (10) carries a back support (18), on the lateral edges of which side plates (22) are swivellably arranged. Each side plate (22) is held by a hinge arrangement (24) into which is integrated a locking device which makes it possible to adjust the side plates (22) in fine steps into a multiplicity of angular positions relative to the back support (18) and to lock them in the respectively chosen angular position in such a way that they cannot be swivelled. The lock is released by lifting the side plate (22) slightly. The back support (18) has the same hinge arrangement with a locking device, allowing it to be locked in any desired inclined position.

Abstract: A supersonic expulsion fuse for interrupting fault currents in high voltage alternating current networks, has an arc interruption region with a long length of supersonic turbulent flow and little or no subsonic plasma. This increases the arc interrupting capability against both thermal and dielectric arc reignitions. Therefore, the transient recovery voltage the network applies across the interrupted arc after current-zero may be increased in both frequency and peak values, relative to known expulsion fuses. The fuse may be used on power distribution systems as a power fuse in enclosures or overhead where the system transient recovery voltages exceed the capabilities of conventional distribution cutouts.

Abstract: A post secondary magnetic amplifier circuit for operation at frequencies at or above 100 kHz with minimal losses is described. A magnetic amplifier is used to control the post-secondary current to an LC filter in which the magnetic amplifier is constructed using an non-nickel core material such as ferrite having a very narrow B-H operating curve (flat loop) in which the remanence (residual magnetism) is below 1000 gauss. The magnetic amplifier then operates as a controlled inductance so that saturation is approached slowly.

Abstract: A static image video telephone transmission method in which a static image signal obtained from a camera is modulated into an audio signal, and the modulated static image signal is transmitted and received over a telephone line. A reference frequency signal is added to a control information signal of a static image signal to be transmitted at a predetermined cycle in order to correct a frequency shift which will occur in the telephone line. The reference frequency signal of the static image signal received over the telephone line is counted by a given clock and the obtained count value is then compared to a predetermined value to detect a quantity of the frequency shift. A demodulation timing signal is corrected based on this frequency shift data.

Abstract: In the resolver, the stator and the rotor in each case have disc-shaped iron parts (4; 8), between which an axial air gap (14) is formed in the shape of an annular disc. The windings (11, 12, 13) are constructed as spiral conductor tracks on films, which are bonded to the ends of the iron parts (4; 8) of the stator or of the rotor. This results in the resolver having a very short axial length. In addition, the zero voltage is reduced by the absence of winding ends.

Abstract: An optical fiber is joined, preferably with an ultraviolet curable adhesive, to a strip of a flexible support material such as a plastic tape to form an optical fiber assembly. The assembly is wound onto a bobbin to form an optical fiber canister, which is then paid out upon demand.

Abstract: A system for transmitting a comb of radar signals. The invention includes a phase shifter for shifting the phase of an input carrier signal. A frequency modulation signal is adjusted in amplitude by an attenuator 16 and input to a balanced mixer 14. The balanced mixer 14 mixes the input carrier signal with the attenuated frequency modulation signal. A summer 20 combines the output of the phase shifter 12 with the output of the balanced mixer 14. The system 10 of the present invention provides an inexpensive means of generating and receiving a complex of illuminating signals having a spread spectrum consisting of lines (teeth) of carrier frequencies with controllable power. The system 10 is agile in that the power levels and the spectral positions of the teeth may be varied.

Inventor: OLSSON KJELL
IPC: G01S7/02
Filed: 1990-08-29
Abstract: The invention relates to a radar arrangement of the type comprising a transmitter which essentially continuously transmits a modulated carrier wave signal and a receiver for receiving the carrier wave signal reflected at an object (echo signal). The carrier wave signal is modu­lated with a code-generating signal (14) whose funda­mental frequency, the code frequency, is determining for the range resolution of the radar. The code of the code-­generating signal (14) is furthermore such that one bit in the code has a duration which is several times longer than the time of a period of the carrier wave signal and a code of several bits forms a block which is charac­terized by modulation of a carrier wave with constant frequency. The frequency of the carrier wave is changed between blocks so that the transmitter sends a block with a carrier wave frequency which is different from the carrier wave frequency or frequencies which the receiver is set up to receive. The receiver stores (14a) the transmitted code and correlates it with the received signal. When code correspondence (synchronism) is obtained this corresponds to a definitive position of the echo response reflector. By changing frequency between blocks, different range zones can be treated in different ways, that is to say different "types of radar" can be dedicated to different range zones. By this means, a radar arrangement is obtained which is adapted to cope with modern threat environments. The radar is difficult to spot, difficult to define and to disturb.
