Filed: 1973-07-02
Abstract: 1437366 Deuterium enrichment of H 2 O, H 2  or a gaseous mixture containing H 2  SULZER BROS Ltd 2 July 1973 [30 June 1972] 31527/73 Heading C1A A deuterium enriched stream of water, hydrogen or a gaseous mixture containing hydrogen is produced by (a) catalytically transforming a D 2  depleted H 2  stream with CO 2  to form D 2  depleted H 2 O and CO, (b) separating the CO and adding it to a D 2 O rich H 2 O stream, (c) catalytically transforming the CO and D 2 O rich H 2 O stream into CO 2  and D 2  rich H 2 , (d) isotope exchange, using as a catalyst the D 2  rich H 2  and CO 2  with fresh water to produce a D 2 O enriched water stream, part of which may be taken as product and part of which is used to react with the CO and also the D 2  depleted H 2  stream and CO 2  which is the feed stream to step (a) above. The process may be modified by the use of a two stage catalytic transformation process and also by the use of a transfer column, whereby the D 2 O enriched H 2 O from the isotope exchange is further exhanged with the CO stream which contains H 2 O vapour to produce a D 2 O enriched H 2 O vapour stream containing CO which is converted to the D 2  enriched H 2  stream containing CO 2  and also a D 2 O depleted H 2 O stream which is recycled to the top of the first isotope exchange column. The D 2  enriched H 2  product of gas containing such H 2  may be taken from the gas stream fed to the bottom of the isotope exchange column.

Title: Improvements in actions for keyboard instruments
IPC: G10C1/06
Filed: 1964-08-05
Abstract: 1,019,110. Musical instruments. R. SEYBOLD. Aug. 5, 1964 [Aug. 6, 1963], No. 31741/64. Heading G5J In a keyboard instrument where each reed or similar sound generator is plucked, the plectrum is carried on a lever arm 2a-2b and plucks the reed on the upward movement of the arm, but on the downward movement the arm rocks sideways so the plectrum misses the reed. The lever arm initially rests on a lifter 12 on the key 13, but after the arm has risen and plucked the reed the screw 10, on meeting the surface of the arm immediately below the cam surface 8, pushes the arm off the left hand end of the lifter. The plectrum is thus rocked sideways and held clear of the reed as the arm is pulled back by spring 9 into its initial position. Upon release of the key the lever-arm resumes its rest position on the lifter. By rotating the eccentrically mounted plectrum to enable more of the plectrum to make contact with the reed and by adjusting the rise height of the lever arm by screw 10(a) the intensity of the sound produced by each reed can be adjusted. Depression of the key also lifts the damper 16 off the reed by means of lever 20 and arm 15. Lever 18 can lift all the dampers off the reeds independently of the keys and lever 20(a) can render the damper mechanism inoperative.

Title: Improvements in or relating to washing machines
IPC: D06F15/00
Filed: 1947-12-03
Abstract: 640,535. Washing machines. MATTHIAS, E. Dec. 3, 1947, No. 31938. Convention date, Jan. 16. [Class 138 (ii)] A washing-machine has a reciprocating agitator which is hydraulically operated by domestic water mains pressure by means of a control member separate from the washing- machine, the control member being connected to the machine by a single pipe which serves both as a supply pipe and a discharge pipe, the water being admitted and discharged at the control means. The washing-machine comprises a container 1, which may be fitted with heating means, having a lid 2 secured by spring clips and which carries a cylindrical member 4. Water pressure is admitted intermittently by the device 17 into the top of the cylinder 4, each pressure impulse causing the piston 4, piston-rod 6 and dolly 15 to descend, the two compression springs 7, 8 causing the piston and dolly to rise immediately after each impulse. The device 17 converts the steady water pressure from the tap 26 into intermittent impulses, and is shown in Fig. 2. The device comprises a pair of spring-loaded pistons 21, 22, the spring 23 being a light spring so that the piston 21 is moved down at minimum water pressure, whereas the spring 24 is stronger, and is of such a strength that a low pressure, e.g. 1.5 atmospheres, is sufficient to depress the piston 5 and the dolly, but will have no effect on the piston 22. With the pistons in the positions shown, water is turned on and passes through passage 28 into piston 22, and via ports 30 to the top of the working piston 5 and also through passage 32 to the top of piston 21. Piston 21 is depressed, and the annular groove 37 in the piston places passages 39, 38 in communication with the discharge orifice 40, thus permitting the escape of any water which leaks past piston 22. Piston 5 is also depressed to impart a working stroke to the dolly 15. When piston 5 reaches its lower extremity, back pressure builds up in the pipe 13 and above the piston 22 until it is sufficient to depress the piston 22 against its spring 21. The supply to pistons 5 and 21 through ports 30 is then cut off. and annular groove 42 joins passages 41 and 40 to permit piston 5 to rise under the influence of springs 7, 8 and piston 21 to rise under the influence of spring 23, the water displaced by these pistons passing from passage 41 via annular groove 42 into the discharge orifice 40. The piston 21 now occupies the position shown and water can pass through passage 34, 35, annular groove 36, to passage 38, 39 to the underside of piston 22, which then rises to the position shown, whereupon the cycle recornmences.

Filed: 1960-09-16
Abstract: 963,844. Tunnel diode oscillating circuits; F.M. detectors. STANDARD TELEPHONES & CABLES Ltd. Sept. 15, 1961 [Sept. 16, 1960], No. 31941/60. Headings H3A and H3T. In a detector for frequency modulated signals comprising a tunnel diode biased in its negative resistance region of its characteristic so as to oscillate at a natural frequency determined by the tunnel diode and a reactance element, the frequency modulated signals are applied to the tunnel diode with the result that the natural frequency of the tunnel diode circuit is synchronized with the frequency modulated signals and the output across the tunnel diode is the D.C. level of the oscillations modulated at the modulation frequency of the applied signal. As shown in Fig. 1, tunnel diode 1 is biased by battery 2 and resistors 3, 4, 5 to operate in the negative resistance region of its characteristic, Fig. 2 (not shown), so as to oscillate at a frequency determined by the inductors 7, 8 and the conductance of the tunnel diode, Fig. 3 (not shown). If a frequency modulated signal is applied to the tunnel diode 1 by means of aerial 10, with the result that the effective bias across the diode at any instant is the sum of this signal and the bias supplied by the battery, the onset of the rise up to Vc, Fig. 5, which would normally occur as soon as the voltage Vb has been reached, is delayed until the applied signal starts on its positive half-cycle after a time corresponding to the point V<1>b when the voltage rises to V<1>c, thus locking the frequency of the oscillations of the circuit to that of the applied signal. The difference between the D.C. levels 15, 14 of the waveforms when there is no applied signal or an applied signal respectively increases as the difference in frequency between the two oscillations increases and the output at terminal 11 is the D.C. level modulated at the modulation frequency of the applied signal. In the circuit of Fig. 6 (not shown), the looked oscillator of Fig. 1 is utilized in conjunction with a modified diode ratio detector, having the advantage of providing amplitude modulation rejection.
