Title: Speed-responsive clutches
IPC: F16D43/12
Filed: 1933-04-18
Abstract: 399,421. Friction clutches. HARDY, SPICER, & CO., Ltd., Birch Road, Witton, Birmingham. April 18, 1933, No. 11329. Convention date, April 19, 1932. [Class 80 (ii).] In a centrifugal clutch comprising a driven plate 16 disposed between a driving flywheel 11 and a presser plate 20 rotating with the latter, weights 32 are carried by stems 31 which extend through slots in a spring-supported plate 22 rotating with the flywheel and which carry at the other end feet 33 engaging in recesses in the adjacent surfaces of the plates 20, 22. Above a predetermined speed, the plate is moved, by the tilting of the feet 33, to the left to engage the plate 16, the reaction being taken by the springs supporting the plate 22. As shown in Fig. 1, the plate 22 rotates with the flywheel due to the provision of lugs 24 on the former engaging slots 25 in the latter, and the plate 22 has projections 21 engaging recesses in the plate 20 to cause rotation of the latter. The plate 20 is urged towards the plate 22 by springs 29 and the latter plate is supported by two sets of springs 27, 28, the set 27 being weaker than the set 28, which latter is initially substantially unstressed, whereby a smooth clutch engagement is ensured. Radial fan blades 35 on the flywheel draw air through openings 36, 37 in the flywheel and housing 8 and eject it through openings 38, 39. radial passages 40 being provided in the plates 16, 20. As shown in Fig. 2, the plate 20 is .caused to rotate with the plate 22 by pins 30 and the plate 22 is caused to rotate with the flywheel by links 44 which pass through slots 45 in the plate and which are pivoted to brackets 43 on the flywheel. The plate 22 is supported from an abutment plate 49 by a single set of springs 46, and the free ends of radial levers 50, which are fulcrummed on the links 44 and pivoted to the plate 22 at 51, engage between the plate 49 and a control sleeve 52. As the clutch engages, the movement to the right of the plate 22, due to the reaction, causes the plate 49 to move to the left, thus increasing the spring pressure. By moving the sleeve 52 to the left so as, through the levers 50, to move the plate 22 to the right, the clutch can be disengaged.

Title: Recording system
IPC: G11B7/00
Filed: 1946-04-12
Abstract: 618,437. Optical sound recording and reproducing apparatus. STANDARD TELEPHONES & CABLES, Ltd. April 12, 1946, No. 11331. Convention date, April 17, 1945. [Class 40 (ii)] A pulse train is modulated by sound or other intelligence and the pulses 50, Fig. 6, are recorded in transverse strips 72 on a photographic film 48. The recording is arranged so that no pulse falls at the end of a strip. The pulses may be modulated in phase, width or amplitude. In one arrangement, Fig. 1, a motor 13 drives both a lens drum 7 for scanning a film 10 with light from a source 5 and a generator 17 which controls the production of pulses in a cusper-type modulator 1 described in Specification 600,244, [Group XL (c)]. The modulated pulses control the light source 5 so as to record the pulses on the film 10. The production of pulses at the scanning limits is avoided by relative adjustment of the magnet 18 and the wheel 17 to synchronize the peaks of the sine wave generated by 17 with the passage of the beam 9 (Fig. 2) over the scanning limits marked by masks 21, 22. The sprocket 12 driving the film is geared to the motor 13 to control the speed of the film. In an alternative arrangement, Fig. 4, the scanning.beam is swept across the film 31 by the application of a saw-toothed voltage from a circuit 25 to the deflecting coils 27 of a cathode-ray tube 26. The intensity of the beam is controlled by pulses from a modulator 28 and shaper 30. An arrangement for reproducing the recorded intelligence is shown in Fig. 5. A beam 35, 40 from a source 34 is made to scan the film 36 which is moved longitudinally. The light transmitted by the film falls on the lightsensitive cathode 41 of a photo-electric cell 42, the output of which is used to operate a reproducer 47.

Title: Improvements in the manufacture of sugar juice
IPC: C13B20/06
Filed: 1946-04-16
Abstract: Sugar juice has its calcium content reduced to a minimum by treatment with carbon dioxide, the process being controlled by measuring and/or recording the bicarbonate concentration.  In operation, the juice is fed by a pipe 1 through a constant level device 2, acidified from the tank 14, to a boiler 3 of a still. The carbon dioxide distils off and is carried by <PICT:0628388/III/1> a current of air to a katharometer 7.  Residue from the still passes through a heat-exchanger 8 to an intermittent syphon 9, thence through an air intake 10 to an air-juice outflow vessel. Air passes through tube 13 to a condenser 5 and carries the carbon dioxide to the katharometer as stated above. The carbon dioxide content may be determined in any convenient manner.  In a modification, the bicarbonate ion is precipitated by adding excess alkaline earth metal salt, e.g. a solution of barium chloride and hydroxide is added to the filtered juice and the resultant turbidity measured photoelectrically.  In a further modification, the pH shift consequent upon the addition of excess alkaline earth metal ion is measured to give the bicarbonate concentration.ALSO:Sugar juice is purified by having its calcium content reduced to a minimum by treatment with carbon dioxide, the process being controlled by measuring and/or recording the bicarbonate concentration.

Abstract: 882,882. Thermal switches. JELSON ELECTRIC Ltd., and MOULSON, J. P. April 7, 1960 [April 8, 1959], No. 11818/59. Class 38 (5). A micro-break thermostatically operated switch having a contact mounted on a snap-action spring blade and having the operating temperature determined by the adjustment of a control member, has the contact blade carried by a spring-biased movable member so that, when the contacts have opened, if an additional force is exerted on the contact blade the member is free to move to separate the contacts further. A fixed contact 5 is insulatingly mounted on the base portion of a bracket 4 which is U-shaped in section. A trifurcated spring blade 8 is fixed at one end to a floating lever 6 located by lugs 15 in slots 16 of the bracket 4, and at the other end 10 carries the movable contact 13. When the operative temperature rises, a bimetallic element 3 bears down, via an adjustable screw, on the cranked end 7 of the lever 6 which pivots about the lugs 15 until the centre spring blade 8 strikes the temperature setting rod 19 to cause the contacts 5, 13 to snap open, the extent of the contact gap being regulated by a screw 14. The lever 6 is pressed downward by a blade spring 17 bearing beneath lugs 18 on the bracket 4 and if, whilst the bimetal element 3 is still hot, a lower operating temperature is selected by raising the rod 19 by means of the cammed control knob 20, when the force exerted exceeds that required to open the contacts the lever 6 and contact blade 8 will pivot as a unit about the cranked end 7 and will rise against the pressure of the blade spring 17, thus preventing damage to the contact blade and bimetal strip.
