Patent GB-824220-A (GB)
Title: Improvements relating to the desalting of solutions containing electrolytes
IPC: B01J49/09
Filed: 1957-09-11
Abstract: A mixed bed of cation-exchange material having strongly acidic ion-exchange group and anion-exchange material having strongly basic ion-exchange groups, used for removing electrolytes passed therethrough, is periodically regenerated by treating one part of the bed with strong alkali and the other part with strong acid without separating the anion-exchange and cation-exchange constituents and then thoroughly mixing the two parts.  The cation- and anion-exchange groups are sufficiently strongly acidic and basic respectively to prevent appreciable hydrolysis of the compounds formed on regeneration.  Suitable groups are sulphonic acid groups and quarternary ammonium groups respectively. Suitable regenerants are 5% solutions of HCl and NaOH.  Amphoteric ion-exchange material may also be used.  The regeneration may be effected by passing the different regenerants through different parts of the bed or by passing one regenerant through the whole bed and then passing the other through only part of the bed.  In an example a mixed bed of a cation-exchange resin made by sulphonating polystyrene cross-linked with divinyl benzene and an anion-exchange resin obtained from the same polymer by chlormethylation and treatment with trimethylamine is regenerated by treating the whole bed with 5% NaOH and then the bottom half with 5% HCl.

Title: Recording machine
IPC: G07C3/12
Filed: 1949-11-09
Abstract: 686,834. Selective punching-machines. WELFORD, N. T., and WELFORD, A. T. Nov. 9, 1950. [Nov. 9, 1949] No. 28752/49. Class 31 (ii). [Also in Group XIX] A selective punching-machine for recording information registered in a counter and code register (see Group XIX) comprises a Wheatstone morse code keyboard perforator which is modified to punch standard 5- hole teleprinter tape which is fed half an inch after every recording. It is capable of punching twenty-three holes, twenty of which can be controlled, in addition to five smaller holes 4, used for feeding the tape, in a pattern shown in Fig. 2 where the three holes 3 which are always punched signify that any of the twelve possible holes 2 thereabove which are punched indicate the state of the counter, while any of the eight possible holes 1 which are punched indicate the state of the code register. Punch rods 16 corresponding to the holes 1, 2 are slidably mounted in two plates 19, 20, Fig. 3, while punch rods for the holes 3, 4 are fixed to the plate 19 and slide in the plate 20. When a record is required a continuously running motor is engaged by a clutch which allows connected plates 20, 22, between which the paper strip 21 passes, to move towards plate 19 and back through cam mechanism. During this cycle the tape is punctured by the punch rods fixed to the plate 19 but is punctured by or pushes aside each punch 16 according to whether the rod is stopped by the engagement of a projection on an operating bar 11 in line therewith with a slot 6 in the side of a selector bar 5 (a-t), which engagement occurs if the bar is pulled, against the action of a return spring 10, by the energization of a corresponding solenoid 9 (a-t). At the end of the cycle an arm 26 pushes back any operating bars 11 which have been pushed aside. When a recording cycle is initiated by the closing of the H.T. switch a current flows on those conductors M appropriate to the state of the counter and code register and energizes the corresponding solenoid 9, Fig. 7, only one of the twenty being shown, thus setting the selector. bars and closing holding circuits ; currents also flows on conductor N to energize a solenoid 28 controlling the clutch to engage the motor and cause a cam 32 to break the circuit through a multipole relay 31, opening switches 30, 33 and closing switches 34, 35. A high speed relay 37 breaks the holding circuits of the relays in the switch unit and then a relay 38 breaks the circuit to relay 37. At the end of the cycle the cam 32 closes the circuit through the switch 34 to the relay 36 which opens the holding circuits of the solenoids 9 and then relay 31 returns the switches 30, 33, 34, 35 to initial position ready for another cycle.
Patent GB-399323-A (GB)
Title: Automatic cut-off for calorimeters
IPC: G01N25/42
Filed: 1932-10-15
Abstract: 399,323. Calorimeters. MASTERTON, W., 75, Warrender Park Road, Edinburgh. Oct. 15, 1932, No. 28821. [Class 97 (iii).] In a water-flow gas calorimeter, upon failure of the water supply, a quantity of water contained in reservoir runs into and chokes a U-tube through which the gas supply passes, thereby cutting off the gas. The latter passes to pipes H, K, leading to a " bleeder " burner and the calorimeter respectively, through a U-tube A, having the upper end of one limb communicating through an S-tube D to a sealed water reservoir B. A wide tube C passes from near the top of the reservoir through the bottom thereof and dips into a cup E with a small hole in the bottom and an overflow pipe higher up. The water outlet F from the calorimeter normally keeps the cup E full and the difference of liquid levels in the tube D and cup E is maintained by the pressure of the gas supply. If the water supply from the outlet F fails the cup E drains through the small hole, exposing the lower end of the tube C, and the unsupported column of water in the tube D and reservoir B flows into and seals the U-tube A. Failure of the gas supply also allows the water in tube D to flow into and seal the U-tube A. The pressure of the gas supply may be indicated by a scale L against the S-tube D.
