Title: A spring release tine
IPC: A01B61/04
Filed: 1981-02-11
Abstract: The invention concerns a spring release tine. The tine includes a shaft (10) equipped with a soil working formation (12) at one end. The other end of the shaft (10) is pivotted through a pin (16) which is journalled in a sleeve (18) fixed to a frame (14). A pair of heavy duty springs (20) are connected on opposite sides of the shaft (10) between a lug (22) on the shaft (10) and a bracket (24) fixed to and subtended from the frame (14). An increase in spring force is counteracted by a progressive change in the moment arm ratio of the tine whereby the load on the soil working formation remains substantially constant upon deflection. The draught on a vehicle pulling an implement equipped with such tines also remains substantially constant when one or more of the tines are deflected. <IMAGE>

Title: Switchable filter circuits
IPC: H03H7/01
Filed: 1981-03-17
Abstract: A switchable filter circuit 4, 5, 6 for use in a receiver to select a first or a second frequency band from a received signal and for providing predetermined minimum stop band attenuation at frequencies outside the selected frequency band lying wholly within the first. A first filter element 4 defines a primary pass band corresponding to the first frequency band, and a second filter element 5 defines a secondary pass band corresponding to the second frequency band. The stop band attenuation of filter 4 is at least as great as the predetermined minimum stop band attenuation required, and the stop band attenuation of filter 5 within the primary pass band is that which is required by the application. Thus filter 4 significantly determines the stop band characteristics of the filter circuit as a whole outside the primary pass band. <IMAGE>

Title: Improvements in and relating to display arrangements
IPC: H03J1/04
Filed: 1981-05-29
Abstract: A display arrangement for displaying and controlling an operating parameter e.g. frequency of a frequency synthesizer, comprises a disc 30 which is manually rotatable. The disc carries slits 36 which rotate through the light patch between a light source and a photoelectric transducer 38 and the consequent pulses operate a counter to control the parameter. In addition, however, they activate liquid crystal numerical display units 32A...32M carried on the disc so that the particular LCD unit (32E) in the centre of a display window 22 shows the instantaneous frequency of the synthesizer. As each LCD unit 32 comes into position in the window 22, its displayed value is automatically set to its required value. In this way, the disc may generate the effect of an infinitely long scale. The values displayed by the LCD units are not changed while they are visible in the window 22. <IMAGE>

Patent GB-2154104-A (GB)
Title: Test apparatus
Inventor: WANT TREVOR LESLIE BARRY
IPC: H04J3/14
Filed: 1984-02-09
Abstract: A test apparatus for determining the reception at a communications receiver of a predetermined data pattern consisting of a repeating sequence of digital bytes 1-10 corresponding to either an "ACTIVE" or "IDLE" state, operates by detecting a frequency component associated with the repetition rate of the sequence i.e. by comparing a corresponding byte, 1, in successive sequences in the manner of a digital filter (7-19, Fig. 2), and monitoring the resultant error count. This makes it unnecessary to uniquely identify each bit to determine whether it forms part of the test pattern, as it is sufficient to extract an expected frequency component. The error count is thresholdably higher in the presence of data, compared with the count produced by the test pattern. Distinction may be made between the "IDLE" and "ACTIVE" patterns, by similarly treating the MSB's of the test pattern bytes. <IMAGE>
