Patent GB-132137-A (GB)
IPC: B23Q5/14
Abstract: 132,137. Macnab, J., and Smith, G. H. Dec. 16, 1918. Variable-speed and reversing gearing. - A multi-speed headstock for lathes has two intermediate shafts, each having two independent and two connected pinions thereon, the former being free to rotate on one shaft and the latter on the other. The shaft b drives the intermediate shaft g in either direction through clutch c and gears c, h, or clutch d and gears f, i, j, the last two being in gear although not. so shown. The gears j, n are feathered to slide on the shaft g so as to enter and drive either of the gears k, m loose thereon which in turn drive the shaft p through the fast gears q, r or if the gears j, n are in their mid position the loose gears s, t driven thereby may be moved to enter and drive either of the gears q, r and so the shaft p. This shaft drives the tool spindle directly through the loose gears u<1> when moved. to the left to engage the, clutch, member v of the fast gear w, but when moved to the right they engage the gear x' driven through gears x, w<1>, w. This arrangement gives eight speeds in either direction. To avoid both of the pairs of gears j n and s, t being moved out of their inoperative mid-position at the same time, both operating yokes 0, 2 are normally locked by pins 3, Fig. 2<A>, on sleeves on the spindle 4, which are moved axially therewith'but are held from rotation. The spindle has fast thereon an arm 5 with projections 6, 7 adapted to engage recesses in either of the yokes 0, 2, such yoke being freed at the same time by the withdrawal of the corresponding pin 3 and capable of being moved in either direction by rotation of the shaft 4 while the other yoke is kept locked. The shaft 4 is operated by a lever 10 pivoted thereto and engaging by means of a ball end 11 a slot in the frame.

In a multichannel communication system in which lower frequency signals are modulated to occupy a higher frequency channel and a high frequency pilot signal is introduced after the modulation, a filter is included in the lower frequency signal path the stop band of which includes the frequency which, after modulation, is the pilot signal frequency. The Figure illustrates the 84-88 kc/s. channel of a twelvechannel system operating in the band 60- 108 kc/s. with 4 kc/s. channel spacing employing a pilot signal of 84,080 c/s. Voice frequency signals VF are applied to a modulator MOD via filters HPF and LPF which limit the signals to the band 300-3400 c/s. A channel signalling tone source CSS at a nominal frequency of 3825 c/s. is also applied to the modulator, but via a band stop filter BSF1 which prevents any components in the band 3890-3950 c/s. being transmitted. The VF and signalling frequencies are modulated up to the band 84 to 88 kc/s. and the pilot signal at 84.08 kc/s. added in the channel equipment SGS to occupy the band corresponding to that of the band stop filter BSF1, i.e. 84.05 to 84.11 kc/s. In the receiving equipment the band stop filter BSF2 is employed after the demodulator DEM in the channel leading to the signalling receiver The pilot frequency being fed to the pilot signal receiver PSR before the demodulator but not removed from the signal path at this point as in conventional systems.

Abstract: 1524495 Phase modulators MARCONI CO Ltd 31 March 1977 [8 April 1976] 13588/77 Heading H3R In an SAW delay line phase shifter suitable for use in a phased array or commutated array antenna system and providing a single of a plurality of constant amplitude outputs with variable and large phase swings (”2# radians), a frequency dependent phase shift is imposed on a variable frequency f 1  or a side-band frequency e.g.f 0 -f 1 ) by passing it through a SAW delay line and this phase shift is transposed on a signal of frequency f 0  by employing modulators M 1 , M 2  to effect appropriate combination and filters BP 1 , BP 2  to filter out unwanted sidebands. The phase of the output signal of frequency f 0  is varied by a variation of the frequency f 1  of oscillator VCO. Effects of the temperature on the circuit operation may be minimized by forming (Fig. 4, not shown) part of the oscillator feed-back phase shift path and the delay line on the same substrate. A plurality of outputs at different phase may be obtained by using different tappings on the delay line. For multi-phased input reception, the multiple inputs (Fig. 3, not shown) are shifted to a side-band frequency by f 1  and the side-bands undergo varying phase shifts before combination and reconversion to the original frequency f 0 .

Class 7(2) [Also in Groups XIII and XXIX] A fan 4 driven through a hydraulic coupling 3 by an engine 1 regulates the temperature of engine coolant circulating through radiator 5 and the engine by way of conduits. 6,.7, movement of a valve 21 controlling coupling filling being effected by a temperature responsive element 8 in the engine coolant circuit. The coupling is of the fixed scoop type in which output speed is proportional to the pressure in the scoop chamber. On a rise in engine coolant temperature, element 8 actuates a valve 26 which in turn actuates the piston valve 21, which movement partially blocks return pipe 17a leading back to the fluid reservoir 16 and hence raises the pressure in the scoop chamber of coupling 3. This pressure is communicated by way of ducts 25, 25a to a piston 23 on a follow-up slide valve 22 which is thereby caused to move against the pressure of a compression spring 24 and in the same direction as the movement of piston valve 21 thus restoring the relative positions of the valve 21 and slide 22 and interrupting the supply of fluid to the coupling 3 to avoid over-regulation and hunting. When the coolant tempertaure falls the element 8 operates the piston valve 21 to reduce the pressure in the scoop chamber of the coupling which movement is followed up as before by a corresponding movement of the slide 22.
