Abstract: 1,253,798. Closure removal device. W.RINK. 20 Oct., 1970 [20 Oct., 1969], No. 49730/70. Heading B8T. A device for the removal and disposal of caps comprises bells 13 situated under a movable platform 9. As a crate 3 containing bottles 2 reaches position 7, a switch 8 is activated which initiates the lowering of the platform which terminates on the activation of a limit switch 16. In an intermediate position, Fig. 2, a clutch 27 engages, causing a pin 21 to rotate. Further lowering of the platform 9 causes a spring 31 to contract, the rotating pin 21 piercing the cap 38. On activation of the switch 16, the platform rises, disengaging the clutch 27, until switch 15 is activated. The initial movement of the pin 21, relative to the stripper 36, causes the cap 38 to be disengaged from the pin, being retained within the bell 13 by an inflatable ring 35. On removal of the bell from the bottle neck, the crate is removed, deflation of the ring 35 then releasing the cap 38 which falls into a container 40 before the arrival of the following crate. In a modification, a pin 22 rotates after insertion into a screw cap 50.  In an alternative disposal means, a sliding platform (58), Fig. 4 (not shown), is placed in position by a wire cable (59). On releasing the caps, the platform (58) returns to its former position, the caps falling into a container (62). When a range of crates, with a corresponding range in bottle size and distribution, are used, the complete platforms may be exchangeable. Those platforms not required for any given crate are raised by cylinders (74), Fig. 5 (not shown). A sleeve (66) then rotates bringing the required platform (72) into vertical alignment with the crate, the platform then being lowered by an hydraulic device (65) into the working position. (For Figures see next page.)

Abstract: 1,204,722. Measuring pressure, fluid-flow electrically; pressure gauges. CONTINENTAL ELEKTROINDUSTRIE A.G. [trading as CONTINENTAL ELEKTROINDUSTRIE A.G. ASKANIAWERKE]. Nov.8, 1967 [Nov.8, 1966], No. 50780/67. Headings G1L and G1N. . In differential pressure measuring apparatus two pressure chambers 5, 6 are separated by a wall 4 and a casing 11, the wall and casing each being provided with a bellows or corrugated tube 10, 13, the bellows, and casing are filled with a non-conducting, incompressible fluid, e.g. silicone oil, and the bellows are connected by a rod 18 whose axial movement, indicative of the pressure difference, is resisted by the application of an equal restering force of an electro-mechanical tranducer, damping of the apparatus being obtained by the provision of throttling restriction 9, 70, 71 in the wall 4 and the provision of non-resilient bellows 50, 60 communicating with bellows 10, 13. As shown, with the higher pressure applied to chamber 5, if it suddenly increases, the non- resilient bellows 50 is compressed against the action of spring 52 until equilibrium between the pressure in bellows 10, 50 and chamber 5 is attained. The liquid in bellows 10 then flows slowly through throttle 9, 70, 71 to the casing 11 and thence to bellows 13, 60, to force on the rod 18 gradually increasing (e.g. oxponentially) to a force proportional to the differential pressure. The time constant of the rise is adjustable by screw 72. Force compensating system. Axial movement of rod 18 causes via levers 20, 21, 22 a movement of a metal member 27 away from coils 28, 29 connected in an A.C. energized bridge circuit 30. The output of the bridge, after amplification, is fed to the coil 34 of an electromagnet in series with a coil 35 on one end of lever 22 in such a way that a restering force is applied to lever 22 and hence to rod 18. A measurement of the differential pressure is obtained from meter 80. The apparatus is described in connection with measuring fluid-flow in pipes, and is of the type described in Specification 990, 313 which is referred to.

Filed: 1968-10-25
Abstract: 1,204,023. Supply circuits for demagnetizing apparatus. RFL INDUSTRIES Inc. 25 Oct., 1968 [12 July, 1968], No. 50864/68. Heading H2H. Apparatus for reducing the magnetic intensity of a permanent magnet comprises a capacitor connected across a " pull-down " coil via a switch to form a ringing circuit, and means for charging the capacitor and controlling the operation of the system. As shown, Fig. 1, capacitors 45 are charged by means of a D.C. voltage produced by rectifier 43. The A.C. supply to transformer 41 is synchronously switched by means of SCRs 17, 18 triggered by pulses produced by a unijunction transistor oscillator 26. A voltage proportional to the voltage on the capacitors 45 is applied to a Schmitt trigger 56 which triggers when the desired capacitor voltage is reached and applies a signal to transistor 36 via OR gate 40 to inhibit the operation of the oscillator 26 and hence cut off the supply to the charging circuit. A monostable multivibrator 66 is simultaneously triggered and switches on SCR 63 for a period of 100 ms. to discharge capacitors 45 through the pull-down coil 61. The capacitors 45 and coil 61 form a resonant circuit which rings to produce a damped oscillating magnetic field around the coil. Monostable multivibrator 66 also provides a voltage for inhibiting the capacitor charging circuit and at the end of the 100 ms. period it triggers a further monostable multivibrator 87 which inhibits the charging circuit for a further period at the end of which the cycle restarts. Controls are provided for selecting the magnitude of the " pull-down " oscillations and for operating the system in continuous or singlestep modes. The system is utilized to " pulldown " the magnetic intensity of an initially saturated permanent magnet to a desired value. The magnetic intensity may be monitored by means of a Gauss meter. In the case of a permanent magnet forming part of an electrical indicating instrument, the desired full-scale current may be passed through the instrument and the magnet pulled-down until a full-scale indication is given. A further system may be provided, Figs. 2 to 4 (not shown), in which a ramp voltage controls the charging voltage of the capacitor so that the amplitude of the successive pulses of damped oscillations increases, the ramp generator being clamped by a signal produced by a Schmitt trigger circuit when the output of a Gauss meter monitoring the intensity of the magnet equals a reference voltage.

Fresh water is obtained from aqueous solutions, e.g. sea water, by passing the solution through heat exchanger 18 where it is heated' by heat derived from a stream of hot fresh water, passing the heated! solution through a series of flash stages 10 at successively lower pressures and temperatures so that part of the water vaporizes from the solution, condensing the vapours in zones 11 by direct contact with a stream of cool fresh water flowing countercurrent to the solution in stages 10, withdrawing (from the system part of the fresh water leaving the condensation zone at highest temperature, and passing the remainder through a prime heater 12 where it is supplied with heat from an external source, before being used to heat further solution entering the system in heat exchanger 18. The cooled fresh water is then recycled through line 17 to the lowest zone 11. The heat exchanger 18 may be of the LLLEX type wherein the hot fresh water is contacted with a water-immiscible oil, and the oil is then contacted with the solution-to-be-heated- Alternatively, the hot fresh water may be submitted to flash distillation, and the flashed vapours are condensed by out-of-contact heat exchange with the solution; this gives rise to twicedistilled water. Heat may be supplied to the fresh water in the prime heater by out-ofcontact heat exchange with steam, or by means of a submerged fuel-combustion, heater, or by contacting the fresh water with vapour withdrawn from the flash stage at lowest pressure and passed to the prime heater via a compressor. In an alternative embodiment, the vapour from one or more flash stages at low pressure is absorbed in a concentrated solution of a hydrophilic substance, e.g. caustic soda. magnesium chloride, lithium bromide, glycerol or a glycol, and the diluted solution is passed to a regenerator where it is evaporated at higher pressure to obtain steam for supplying to the prime heater. Instead of being used to Obtain fresh water, the system may be employed to concentrate solutions, e.g. a sulphite waste liquor.
