Patent GB-2127610-A (GB)
Title: Magnetic disc transducer arm
Inventor: FELLER MARC
IPC: G11B21/02
Filed: 1983-09-22
Abstract: Several magnetic heads 46 cooperate within a stack of discs 34 rotating on an axis 42. For track following a closed-loop servo system is responsive to signals from a magnetic head tracking the underside of the lowermost disc and controls the head position by means of an electromagnetic actuator which includes a coil 24. Coil 24 is mounted on the base arm 48 which carries the magnetic head feeding the servo. The arm 48, in common with arms 62 which carry the other heads 46, is mounted to swing about pivot 44. The placing of the sensing head and the coil 24 adjacent one another at the outer end of the arm 48 minimizes mechanical vibration and allows the use of high gain in the servo-system. <IMAGE>

Title: Screw-action connectors security means
Inventor: RICKWOOD GERALD CHARLES
IPC: F16B39/10
Filed: 1983-11-23
Abstract: A locking device for securing at least two screw-action connectors e.g. wheel-nuts comprises a locking clip or element 64 made from spring steel strip or wire. The locking clip or element 64 has a diagonal interconnecting part 64' (i.e. between X and Y) which extends tangentially between a pair of locking elements 65, one at each end of the part 64'. The locking elements 65 (for example, coils) are wrapped round or placed over a portion of a wheel nut 66 or 67. The interference/friction fit between the wheel nut and the clip or element 64 prevents axial movement of the clip relative to the nut. The part 64' serves as restraining means positively linking tangentially adjacent wheel nuts 66 and 67 and thereby prevents relative rotation thereof. <IMAGE>

Patent GB-2267198-A (GB)
Title: Interference reduction
Inventor: MASSEY NICHOLAS ROGER
IPC: H04B1/713
Filed: 1984-05-12
Abstract: Interference on a prospective communication channel is preassessed and a filter arrangement 58 preset so as to suppress the interference when the system moves onto that channel. The channels may be those of a frequency hopped transmitter 30 which transmits on the upper and lower sidebands during the first and second halves respectively of each hop period. A receiver 32 monitors both sidebands continuously, passing the USB over switch 38 to the filter bank 58 through a one hop period delay unit 48. Switch 40 passes the LSB output (which will comprise merely the interference) to channel 50 which assesses the interference frequencies and stores this data at 54. During the next half hop period, switches 38 and 40 change over and the LSB output from the transmitter passes into the delay unit 48 while the USB output, carrying only interference, passes to the assessment circuit 52. The store 54 data sets the filter 58 to suppress the interference previously detected for the sideband output currently passing through the filter. <IMAGE>

Title: Starting control apparatus for automatic speed change gears
Inventor: TATENO TOSHIAKI
IPC: B60W10/11
Filed: 1986-03-28
Abstract: An accelerator false signal voltage (VAC), which is determined on the basis of an object number of rotations per unit time of an engine and an actual number of rotations per unit time thereof detected by an operational condition detecting means, is outputted to an engine control means to increase the actual number of rotations per unit time of the engine to the object number of rotations per unit time thereof. When the number (NE) of rotations per unit time of the engine has reached a peak, the determination of whether this number (NE) and the number (NCL) of rotations per unit time of a clutch agree with each other is made, and, when the agreement is detected by a means for detecting the synchronous rotations of the engine and clutch, the clutch (15) is completely engaged. When the non-synchronous rotations of the engine and clutch have been determined, the clutch (15) is controlled through a clutch engagement judging means so that the clutch (15) is operated in a half-engaged state. When the incomplete engagement, which is done by the clutch engagement judging means, of the clutch (15) has been detected by a clutch position detecting means, a signal for gradually decreasing the accelerator false signal voltage (VAC) is outputted to the engine control means from a means provided for this purpose. This means for gradually decreasing the accelerator false signal voltage (VAC) as well as the operational condition detecting means, means for detecting the synchronous rotations of the engine and clutch, clutch engagement judging means and clutch position detecting means constitutes a starting control apparatus for automatic speed change gears according to the present invention. <IMAGE>
