Abstract: 438,987. Variable - speed gearing. McGILL, H., 42, Talbot Avenue, Canterbury, Bourke, Victoria, Australia. Aug. 27, 1934, No. 24666. Convention date, April 12. [Class 80 (ii)] An automatic variable - speed gear or torque converter comprises planet gears 11, Fig. 1, supported in a carrier 3 fast on the driving-shaft 2 and meshing with a sun gear 12 fast on a driven shaft 13. Each planet 11 is controlled by a separate system of eccentric masses 16, Fig. 5. Rigid with each planet 11 is a disc 14, Fig. 2, carrying a ring of pivots 17 upon which are jointed links 18 which are pivoted each to a weight 16. The weights 16 of each group are supported internally and externally in an annular track 21 in a member 22 which is carried by the planet-carrier 3 and is either rigidly secured thereto or, as shown, revolubly mounted at 23 on a pin 24 fast to the carrier 3. The axis of the track 21 is eccentric to its planet 11 and the eccentricity does not vary. During transmission, as the planets 11 turn on their own axles, the weights 16 close in and open out as they are carried round in the eccentric tracks 21. This continual mutual displacement of the weights resists the turning of the planets on their axes so that an elastic torque is applied to the driven wheel 12. Driving and driven shafts 2, 13 may interchange functions. Specification 422,432 is referred to.

Title: Desalination of liquids
IPC: B01J47/10
Filed: 1972-05-30
Abstract: 1392875 Desalination of water MANNESMANN AG 30 May 1972 [1 June 1971] 25139/72 Heading B1J A method of desalinating water or other liquid using one or more ion-exchange resins comprises the steps of feeding the liquid to be desalinated continuously upwards through a solid exchange resin bed in an absorber, continuously feeding spent resin from the absorber to one or more regenerators by means of a sub-stream of the desalinated liquid, continuously withdrawing a mixture of regenerated resin and the desalinated liquid substream from said regenerator or regenerators by means of an injection pump through which the liquid to be desalinated is fed on its way to the absorber to serve as propellant liquid, and recycling said mixture to the absorber with the liquid to be desalinated, where in order to regulate the level in said regenerator or regenerators and thereby to regulate the level of the bottom of said resin bed in the absorber, a sub-stream of the liquid to be desalinated is branched off before it enters said pump in an amount corresponding to the desired resin bed level and fed to the liquid to be desalinated leaving said pump or to the resin-desalinated liquid mixture entering said pump. As shown, water to be desalinated enters a bed 3 of ion exchanger via pump 9, the bottom of the bed being maintained clear of the bottom of the absorber by the force of the flow. Desalinated water leaves at 5 and spent resin at 6 to be regenerated and fed back by being drawn into pump 9. Part of the raw water flow is branched off by line 10 or line 10' under the control of valve 11 or 11' respectively and fed to either the suction intake or the output of pump 9. Valves 11 and 11' may be controlled by sensors 12, 13 in the regenerator 7 so as to maintain the top of the resin in the regenerator between the levels of these sensors and thereby control the level of the bottom of the bed 3.

Abstract: 1529116 Automatic frequency control INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 16 June 1977 [25 June 1976] 25157/77 Heading H3A In a receiver including a controllable oscillator 1 the frequency of which is controlled by a control loop, including an adjustable frequency divider 6, a frequency comparator 8, a reference frequency 9 and a changeable time constant circuit 10, in dependence on the output from a memory circuit 7 fed to the divider 6, the time constant of circuit 10 is changed to cause the control loop to operate at a higher speed while the receiver is being tuned to a selected frequency than it does when subsequently maintaining the receiver in tune to the selected frequency. When a channel is selected by a keyboard 40, or on turn on of the receiver which provides a signal via (43-45, Fig. 2 not shown), a signal is fed via an OR gate 13 (41) to close an electronic switch 37, such as a CMOS switch, so as to reduce the time constant (35, 36) of a LPF 10 and so adjust the control loop at the higher speed while the receiver is being tuned. The control loop also includes a divider 5 and an amplifier 11. The frequency discriminator 8 includes a monostable (24, 26, Fig. 2, not shown) fed with the reference oscillation from a quartz oscillator 9, and an electronic switch such as a CMOS switch (28) operated by the output from the divider such that the output of the switch (28) is integrated over a number of cycles by a capacitor (31) to produce an output via a FET 30 which is fed to the LPF 10 (35, 36).

Filed: 1962-06-30
Abstract: 970,252. fluid-pressure servomotor systems. B & S. MASSEY & SONS Ltd., and G. WILSON. Oct. 5, 1962 [June 30, 1962], No. 25184/62. Heading G3P. A double-acting servomechanism suitable for operating the control valves of forging hammers &c. comprises a hollow piston 11 housing a relatively fixed, ported sleeve 12 containing a control piston 25 operated by a hollow stem 14 through which it is supplied with pressure fluid through a non-return valve 35. The control piston is loaded by a spring 34 so that it can be operated by a wire &c. With the control piston in the neutral position shown fluid can circulate from the stem 14 through radial bores 27, annular grooves 28, 29, 30 and deep annular grooves 31, 32 leading to axial bores 36 which communicate with the bore 12a of the sleeve 12 leading to exhaust 25a. The grooves 29, 30 communicate respectively with chambers 20, 19 on either side of a central portion 18 of the piston 11 through radial holes 24, 24a and axial grooves 22, 23 in the sleeve and radial holes 21 in the piston. Movement of the control piston in either direction causes one side of the piston 11 to he pressurised and the other to be connected to exhaust to cause a corresponding movement of the piston 11. The non-return valve 35 reduces the tendency of the piston 11 to overshoot, but this tendency is further reduced in a modification in which the non- return valve is housed within the control piston and exhaust from either chamber 19, 20 takes place through passages in the main cylinder 10 of the apparatus which passages contain linked exhaust valves so arranged that pressurisation of one of the chambers 19, 20 causes closure of the corresponding exhaust valve and opening of the exhaust valve of the other chamber. Each end of the cylinder 10 has drain passages 17 and felt scraper rings 38.
