Title: Wheelchair with a forward tilting or reclining seat, fixed front and castored rear wheels.
Inventor: PENNINGTON-RICHARDS CYRIL MONT
IPC: A61G5/14
Filed: 1994-12-16
Abstract: A wheelchair comprising a frame 1 joined by perpendicular crosspieces, having large, fixed front wheels 6 and castored rear wheels 3. The seat 8 is pivotably attached to a backrest 14 and legrest 13 which are connected 17 to ensure that they rotate together. The seat is pivotably suspended from the top of the frame at 12 so that it and the rests are tiltable relative to the frame with the extent of the tilt restricted by a releasable strut 18 pivotably attached to the seat and releasably engaging a frame crosspiece 4. A pivoting block brake mechanism 24 is connected 27 to the seat so that the chair is immoble when the seat is tilted forwards. There is provision for an adjustable, counterbalancing spring 34 to be attached between the rear of the frame and a vertical extension of the suspending pivot point of the seat 33. <IMAGE>

Title: Reception volume limiting circuit for telephones
Inventor: YOSHIDA TOSHIO
IPC: H03G11/00
Filed: 1994-12-23
Abstract: A reception volume limiting circuit includes a detecting section 7, an A/D conversion section 8, a control section 9, and a speech data calculating section (23). The detecting section 7 performs detection/rectification and smoothing of a receiver driving AC signal and outputs a DC signal corresponding to the level of the receiver driving AC signal. The A/D conversion section 8 converts the DC signal into a digital signal. The control section 9 calculates a time average value by averaging the digital signal every predetermined time interval, adds the currently stored attenuation amount to the time average value, and compares the corrected time average value with a predetermined threshold value representing a critical sound pressure for protection of listener's hearing. If the corrected time average value exceeds the threshold value, the control section calculates an excess level from the difference between the two values, stores the excess level as a current attenuation amount, and outputs a volume attenuation command having the excess level as an attenuation amount. The speech data calculating section 23 performs subtraction processing of the reception speech data, in response to the volume attenuation command, on the basis of the excess level included in the command and outputs reception speech data attenuated by a value corresponding to the excess level. <IMAGE>

Patent GB-2335322-A (GB)
Title: Phase detector
Inventor: LINDQUIST BJOERN
IPC: H03L7/089
Filed: 1998-03-13
Abstract: A phase detector triggers on both rising and falling edges of an input pulse signal for doubling the frequency of an input signal Vref. When the phase detector is used in a phase locked loop, the doubled frequency means that a lower division ratio can be used, thereby reducing any noise contribution introduced thereby. The phase detector comprises first and second flip-flops 28,30 triggered respectively by the rising and falling edges of the input signal Vref. A further flip-flop 32 is triggered by the rising edge of a comparison signal at 14. An AND gate 44 is responsive to the outputs of the OR gate 36 and the output of flip-flop 32 to reset all the flip-flops. The phase detector also includes a chargepump 40 to produce an analog output representative of the phase difference detected. The phase detector may form part of a phase lock loop including a frequency divider to which a data modulation signal may be applied (Fig. 1 not shown).

Patent GB-2342342-A (GB)
Title: A control device for boom-mounted agricultural equipment
Inventor: CULLEY JOHN GEORGE
IPC: A01M7/00
Filed: 1998-09-08
Abstract: Boom-mounted agricultural equipment such as spraying equipment is controlled by a switching device (28, fig.3) which switches on/off individual sections of the boom (20, fig. 3), a timing device (26, fig.3) for operating the switching device and an input device (24, fig. 3) for determining the timing of the switching operations. This is especially useful when spraying a crop in an irregularly shaped field, as it minimises the amount of crop which is over-sprayed or missed. An angle setting device (34, fig.4) may be employed to set the angle of the edge of the field in relation to the direction of the boom, and this information forms the input to the timing device which turns off/on the boom sections in turn as the edge of the field is approached by different sections of the boom at different times. The control device (14, fig.3) has means for determining the timing of the switching operation based on time based inputs, such as when the two ends of a dummy boom (48, fig.8) positioned at the front of the tractor respectively pass the edge of the field (see figure 8).

Patent GB-2346415-A (GB)
Title: Vibration damping
Inventor: BAGNALL STEPHEN MORAY
IPC: C23C10/60
Filed: 1999-02-05
Abstract: Viscous damping of vibrations of structural elements eg gas turbine blades occurring at elevated temperatures is achieved by applying to a body (6) of the element (2) a coating (20) that includes an inner bonding layer (22) of a material which undergoes a transition to a more ductile state at the temperatures at which the vibrations are to be damped, and an outer ceramic oxide layer (24) secured to the body by the bonding layer. Viscous shear can then occur in the bonding layer as the relatively rigid outer ceramic oxide layer is subjected to the vibrations, so damping their amplitude. The materials of the bonding and ceramic oxide layers can be those conventionally used for thermal barrier coatings. The coating may be applied to a portion only of the blade.
