Title: Fixing structure of dielectric resonator
Inventor: WAKINO KIKUO
IPC: H01P7/10
Filed: 1990-12-27
Abstract: A fixing structure of a dielectric resonator 1 which does not require a support block for installation on a microwave circuit board having a microstrip line 3. The dielectric resonator 1 is directly fixed to the microwave circuit board 2 such that mutually facing plane pants 1a, 1b do not face one plane of the circuit board. A support block is therefore unnecessary and as a result of which cost reductions can be attained together with simplified work processes. Further, an electrode film, 1e, Fig 4 may be formed on a flat part 1d provided on a portion of the outer periphery 1c of the resonator 1, and the resonator is fixed on the circuit board with the flat part facing upwards. A metallic case to cover the circuit board can be brought close to the dielectric resonator, thus realizing a reduction in the size of the required case. The resonator 1 can be set at an acute angle  theta  (Figs 3 and 6) to the microstrip line 3. <IMAGE>

Title: A rotating magnetic head for a magnetic recording reproduction system
Inventor: MITSUHASHI YASUO
IPC: G11B5/53
Filed: 1991-01-11
Abstract: A rotating magnetic head for a magnetic recording reproduction system, comprises a head position detector (114) which detects the position of the rotating head (103, 104) placed on the periphery of a rotating drum (107), and performs servo control of the position of the movable head. The detection of the position of the rotating head is realized by an optical, non-contact mechanism (104) or by detecting the difference of the track scanned by fixed heads. The former requires more than one movable heads and the latter requires a fixed head. <IMAGE>

Patent GB-2252420-A (GB)
Title: Weighing apparatus
Inventor: ELSWORTH JAMES EDWARD
IPC: G01G1/18
Filed: 1992-01-10
Abstract: The weighing apparatus (1) comprises a beam (2) which is supported by a knife edge (3) on a frame (4). A receptacle (5) is suspended from the beam (2) on a knife edge (6), and a weight box (7) is suspended from the beam (2) on a knife edge (8). The beam (2) is provided with an anchoring means (9) to which is attached a tension spring (10) carrying a slipper (11) slidably mounted on a support (12) that is part of the apparatus frame (4). In use a mechanical system moves the slipper (11) to a position between the beam (2) and the slipper support (12), and a weight (13) is added to the weight box (7). The turning moment of the weight (13) causes the beam to rotate and this in turn causes the slipper (11) to be nipped between the beam (2) and slipper support (12). The mechanical system used for moving the slipper is then removed. As the spring (10) is now extended, it provides a biassing force that biasses the slipper out of the nipped position. Flowable material is added to the receptacle (5) through an input valve and as the weight of the material in the receptacle increases so the beam-derived load on the slipper (11) - the "nipping" load - progressively decreases until a point is reached at which the biassing force is able to remove the slipper from the nipped position. This removal is detected by sensing means which causes the addition of material to the receptacle to be stopped.

IPC: F16D3/10
Filed: 1992-06-20
Abstract: A phase change mechanism, for varying the phase of an engine camshaft relative the engine crankshaft, comprises a drive member 10 connected to the camshaft drive, a driven member 14 connected to the camshaft. Torque is transmitted from the drive member 10 to the driven member 14 through pins 12, 16 which engage a coupling element 18. To vary the phase between the drive and driven members, the coupling element is allowed to move relative to them. A one-way clutch 22 rotates an inertial member 20, with the drive and driven members, having an eccentric crank (20' fig 2) acting on the coupling element so as to vary its position in dependence of the angular position of the inertial member 20. In order to arrest rotation of the inertial member at predetermined angular positions latching means is provided comprising an abutment surface (24, fig 2) projecting radially from the inertial member, a latch member 28 mounted between a pair of shaped blocks 26, 26', fixed to on one of the drive and the driven members, for limited transverse sliding movement (see fig 2). The latch member has a pair of opposed abutment surfaces (40, fig 2) which engages the abutment surface (24, fig 2) on the inertial member. Switching means, for moving the latch, which may comprise a ring electromagnetic coil 38, mounted to an engine block and two permanent magnets (34,36; figs 2 & 3), fixed to latch member 28, having their opposite poles facing radially outwards. Polarity of the coil 38 (see fig 3) may be reversed so as to either repell or attract each magnet (34, 36; figs 2 & 3).

Title: Nethod of operation of a trunked radio system for data transmission
Inventor: ZEHNGUT ILAN
IPC: H04W84/08
Filed: 1993-08-27
Abstract: A trunked radio system is described of the type in which a trunking controller (30) controls the operation of the system by transmitting channel grant commands and a talkgroup indications for assigning channels to talkgroups of radios. Each radio (14, 24) is by default a member of a paging group and receives messages transmitted by the host radio (40) on a paging group channel. For transmission of data, each radio (14, 24) is arranged to temporarily assign itself to a session data group, such that on transmission of a session data group channel grant by the trunking controller, the radio responds to that channel grant by tuning to a session data group channel. The radio performs a multiple access contention process to access the session data group channel and commences data exchange with the host computer on that channel. A trunking radio data modem (12, 22, 42) is described which enables this operation on a normal trunking system. <IMAGE>

Abstract: A closable valve 1 connected to the air line hose of a diver's breathing apparatus between an air tank and a mouthpiece, can be closed and opened selectively by the diver in the event of malfunction of the mouthpiece valve. The valve 1 includes a chamber 6 defining a seat 8 on which a plug 10 may sit to block flow of air from inlet 2 into chamber 6.
