Title: Adjustable damping force hydraulic shock absorber
Inventor: ASHIBA MASAHIRO
IPC: F16F9/46
Filed: 1989-12-12
Abstract: In a shock absorber, a damping force regulating valve comprises an axially movable valve element (33) having one end contactable with a valve seat (32) formed in a passage (11, 13) between two chambers to block the flow of working fluid through the passage. The valve element (33) defines a space (35) on the side of the other end thereof, and a plunger (39) is attached to the valve element, the plunger being formed of a magnetic material. A solenoid (40) axially slidably receives the plunger, and is capable of axially moving the plunger when energised. A permanent magnet (41) can hold the plunger at a position to which the plunger has been moved, and the valve element (33) is formed so that pressure receiving areas (A) and (C) tend to urge the valve closed.

Title: Antenna support providing movement in two transverse axes.
Inventor: SPILLER BASIL HARRY ROYSTON
IPC: H01Q3/08
Filed: 1992-05-01
Abstract: An elevation-over-azimuth platform, e.g. for controlling the positioning of a dish antenna 6, includes an antenna mounted on a shaft 7 which is rotatable about elevation axis 14 and is supported by a yoke 12 which is freely rotatable about azimuth axis 22 by means of bearing 20 on base plate 18, and shaft 62 which is rotatable about its axis parallel to the azimuth axis 22 and is movable along a path concentric with the azimuth axis 22, the shaft 62 being driven so that when it rotates about its own axis only the elevation of the antenna is controlled and when it moves along the path without rotating on its own axis the movement of the antenna about the azimuth axis is controlled. As shown, inner and outer ring gears 30 and 32 are rotatable concentrically about azimuth axis 22 by means of wheels (e.g. 38, 42, 44) engaging grooves in the outside and inside respectively of ring gears 30 and 32. Spur gear 60, rigidly connected to shaft 62, engages gear tracks on the facing surfaces of the ring gears, and shaft 62 itself passes rotatably through the yoke and is drivingly connected to the shaft 7 via bevel gears 72. When ring gears 30 and 32, driven by respective motors, rotate in the same direction with the same angular velocity, the spur gear and shaft 62 move bodily around the azimuth axis without rotation and carry the yoke with them; azimuthal positioning results. When ring gears 30 and 32 are rotated in opposite directions, but again at the same angular velocity, spur gear 60 and shaft 62 are rotated about their own axis but do not move bodily. Elevational positioning then takes place. <IMAGE>

Title: Audio frequency filter with gain adjusted in dependence on selected frequency  range
Inventor: JOSTINS PETER
IPC: H03G9/02
Filed: 1992-06-26
Abstract: An audio frequency filter for a mixing console equaliser typically has a manual frequency control for setting its operating frequency range, and a manual gain control for controlling the gain of the filter independently of the set frequency range. The present filter further provides gain adjustment means for automatically adjusting the gain of the filter in dependence on the position of said operating frequency range relative to a reference frequency that lies intermediate the lower and upper ends of the audio frequency spectrum. the gain adjustment means being such that the filter gain is greater the further said operating frequency range is moved away from said reference frequency towards a said end of the audio spectrum. As a result, signal frequencies at the extreme of the audio spectrum are automatically boosted. <IMAGE>

Title: Impedance measurement
Inventor: WAKAMATSU HIDEKI
IPC: G01R27/08
Filed: 1992-10-23
Abstract: A system for measuring a broad range of impedance values with high precision and over a broad frequency band is provided. Both the broad range impedance measurement capability of the V-I method and the broadband frequency measuring capability of the reflection coefficient method are provided. A remote measurement capability is also available (e.g. using coaxial cables). Based upon the V-I method, a selection at 22 is made between a cirnuit to achieve an ideal open and a circuit to achieve an ideal short circuit in response to the impedance values. A boundary for selecting the impedance is, for instance, 50 OMEGA . To measure a high impedance, the ideal open type circuit is selected; to measure a low impedance, the ideal short circuit is selected. The source and measuring instruments are extended by a coaxial cable. A floating measuring instrument is obtained by using a balun. Impedance measurements for 1 MHz to 2 GHz are possible. The impedance measured may be a resistance, capicitance, inductance, reactance etc. The switch 22 may be an open or close type of switch e.g. a diode. <IMAGE>

Title: Data transmission in television microwave signal broadcasting
Inventor: HORAN JOHN
IPC: H04N7/20
Filed: 1994-04-12
Abstract: Data (such as encryption data for satellite TV decoders) is transmitted in a broadcasting system without reducing the number of available TV channels. An aerial 2 receives satellite 4 and local radio frequency signals. A master transmitter 5(a) broadcasts a multi-channel television signal generated at a transmitter system 3. This transmitter 5(a) also transmits a 6 GHz signal incorporating data received via a leased line 13 from a computer 14. The data is inserted on a 7.5 MHz subcarrier. The data is dropped off at a next successive headend and the 6 GHz signal is re-transmitted. A television signal is broadcast from each successive headend, which signal includes directly received satellite signals. Extracted data is inserted at the Nicam carrier frequency at a lower bit rate than the usual Nicam bit rate, thereby not effecting the number of TV channels. <IMAGE>

Abstract: For the high-precision measurement of the speed of a system rotating about an axis, a single main counter (HZ) runs uninterruptedly from the start of measurement to the end of measurement and a channel counter (KZ1, ..., KZn) is provided for each of a number n of measuring channels. By stopping a channel counter (KZ) at the associated measurement period end and reading out the counter reading thereof as well as that of a supplementary upper part (HZo) of the main counter (HZ) which contains the higher-order count positions, a determination is made of the total time elapsed from the start of measurement up to the respective detected period end, and thereafter the target period lengths are determined by forming the difference of successive count values. After each measurement the channel counter (KZ) is reactivated and synchronised with the lower part (HZu) of the main counter (HZ). <IMAGE>
