Abstract: 728,445. Acyclic generators; liquid collectors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY OF LONDON. Dec. 22, 1952 [Dec. 20, 1951], No. 29827/51. Class 35. A homopolar generator has collectors which include mercury or other liquid metal. The generator comprises a bell-shaped conducting rotor 12 in the annular air-gap of a magnet 1, 2. The inner and outer poles of the magnet are radially slotted as at 7 to reduce flux leakage. The conducting rotor is of rhodium-silver plated copper and is engaged by mercury collectors 10, 22 at either end of the active part 16 of the rotor. At rest, the mercury 11 rests in the base of a circular groove, but in operation, is flung into the concave peripheral troughs 18, 21, thus making contact between the moving and stationary surfaces. The outer trough member of the lower collector is connected to a sleeve 13 passing back through the working air gap 4. To effect cooling, mercury is fed into the collector at its inner part P and is drained off at the bottom Q by tubes (not shown). In a modification, the curved surface 28 is replaced by a sharp edge. In an alternative shape of collector, Fig. 4, the rotor has an upturned flange of concave section 48, the fixed collector 32 being correspondingly convex. Mercury is fed in at pipe 37 and passes through holes 35 to a pool 36, mercury flung out of the collector being collected in channel 38 and drawn off through pipe 39.

Title: Method of operating fused bath electrolytic cells
IPC: C25C7/00
Filed: 1945-11-08
Abstract: 617,886. Operating fused electrolyte cells. McNITT, R. J. Nov. 8, 1945, No. 29840. [Class 41] A battery of series-connected fused electrolytic cells of the kind in which the anode extends to a point near the bottom of the cell and loss of heat occurs through the anode extensions outside the cell, is operated with such low electric current that insufficient heat is generated to maintain the anode surface sufficiently active for high efficiency of the cell and when an anode of a cell attains this state a supplemental electric current is applied to that cell until the anode becomes sufficiently active for high efficiency while continuing to operate all the other cells at the low current. In the cell shown for producing sodium and chlorine from a fused mixed bath of sodium chloride and calcium chloride, the carbon anode 4 passes through the bottom of the cell and is surrounded by a cathode 8. The cylindrical hollow anode has holes 7 to enable circulation of the electrolyte and a diaphragm 10 suspended from the collector 12, 13 for collecting the sodium and chlorine respectively is interposed between the electrodes. A plurality of such cells are operated in electrical series-connection and as the efficiency of a cell declines supplemental current is fed to the electrodes of that cell from a small portable generator 24. Cooling surfaces 20 traversed by cooling fluid avoid overheating of electrolyte in the sump 19 and prevent impurities precipitated therein from passing into solution. The anode stream of electrolyte is maintained at a high temperature which is controlled by adjusting the position of the thermal insulating baffle 18 and the temperature of the descending cathode stream may be controlled to enhance circulation by cooling surfaces 22 and thermal baffle 23. Specification 617,885 is referred to.

Title: Apparatus for cooling a gas
IPC: F25J3/04
Filed: 1962-08-08
Abstract: 979,935. Refrigerating; heat exchange apparatus. SULZER FRERES S.A. Aug. 8, 1962 [Aug. 15, 1961], No. 30433/62. Headings F4H and F4S.  A gas is cooled by expansion in a turbine 3 which drives a compressor 10 through a gasborne shaft 9, the compressor being located in a closed gas cycle which also includes a heat exchanger 31 and an adjustable throttle 32. Gas of the same chemical composition is used in the turbine; the shaft bearings and the closed gas cycle and the heat exchanger 31 is so constructed that the pressure drop therein is at least equal to that produced in the throttle 32. It is stated that the consequent increased velocity of the gas flowing through the heat exchanger results in better heat transfer so that the size of the heat exchanger and hence the volume of the closed gas cycle may be reduced. Gas from the outlet 12 of the compressor 10 passes downwardly through part annular ducts 33 in the heat exchanger to an annular duct 43 and thence upwardly through return ducts 33a to the throttle 32 and compressor inlet 11, while cooling water supplied through a pipe 49 flows in intermediate ducts 48. The throttle 32 is adjusted axially by a hand wheel 36 and may be controlled automatically, in dependence on the temperature in the refrigerating circuit, to vary the turbine speed. Corrugated strips 42 are provided in duets 33 and 33a. In the embodiment of Fig. 4 (not shown) the heat exchanger is formed as a cylindrical block having sets of bores arranged in circles of different radii and having open-ended tubes therein, the gas and cooling liquid being arranged to flow in the tubes and bores of alternate circles. Reference has been directed by the Comptroller to Specification 870,091.
Patent GB-465175-A (GB)
Title: Improvements in or relating to folding chairs, seats or the like
IPC: A47C7/58
Filed: 1935-11-04
Abstract: 465,175. Folding seats. ALLWOOD, F. W., and KALEE, Ltd. Nov. 4, 1935, Nos. 30463/35 and 2561/36. [Classes 52 (ii) and 52 (v)] In a folding seat for theatres &c., in which the rear of the seat rises relatively to the front part when the user vacates the seat, and the front part moves inwardly towards the rear, the seat 8, Figs. 1 and 2, is pivotally supported by links 11 and the automatic folding is effected by the weight of the seat, augmented if desired by counter-weights or springs. The rear part of the seat is constrained to move in the desired manner by means of links 15, or by guide-ways and pins. The links 11 and 15 are pivoted to brackets 9 on the seat part, and the upper pivot 12 of the link 11 is slightly in front of the lower pivot .13 when the seat is in use. The link 15 is pivoted to the seat back at a point 16 slightly above the level of the pivot 14, and a part 17 thereof abuts in both positions of the seat against a stop 18. Stops 19 limit the backward movement of the links 11. A weight 20 at the front of the seat causes the latter to assume the tipped position when the user rises. In a modification, the links 15 are shortened, and are pivoted to the side frames of the chair. In order to prevent tipping of the seat if the user's weight is brought too far forward, the upper pivots of the links 11 may be modified as shown in Fig. 6. The pin 24 on the bracket 9 engages in a slot in the link 11, and rests on the lower end of the slot when the seat is in use, while a lug 28 on the bracket 9 and a projection 27 on the link 11 come into contact to prevent tipping of the seat. When the sitter rises, a spring 26 on the link forces the pin 24 to the top of the slot so that the lug 28 and projection 27 cannot engage, and the seat folds. Preferably a slight space is allowed between the lug and the projection as shown, so that the front of the seat may be tipped downwardly to a slight extent when in use.

[Also in Divisions C3 and C4] The pigment and active agent of an anticorrosive coating composition is a ferric chromic phosphate obtained either by oxidizing a soluble ferrous salt in an acid medium and in the presence of phosphate ions with at least a stoichiometric amount of a soluble chromate salt, or by precipitation from a ferric salt solution by the addition of a soluble chromic salt and acid and phosphate ions. The first method yields a ferric phosphate chromic phosphate molar ratio of 3: 1, and in the second molar ratios of 5-1: 1 may be obtained. Numerous water-soluble ferrous, ferric, chromate and phosphate salts are listed. The acid is preferably phosphoric acid, thereby contributing the required phosphate ions, but HCl and H 2 SO 4  can also be used. The reaction is carried out from room temperature to 100‹ C., and precipitation is completed by the addition of a base, particularly NaOH. The precipitated pigment is conventionally filtered, washed and dried.

Abstract: 641,364. Fastenings. HOWCROFT, S. Nov. 19, 1947, No. 30683. [Class 44] [Also in Group XXX] A locking mechanism for a lift operating chain or rope and/or a lift gate, of the kind in which a removable operating handle cannot be withdrawn from the chain lock casing to unfasten a door or gate lock until it has been turned to a position to lock the chain, comprises a sliding bolt actuated by a rotary barrel operated by the handle which is inserted into a central slot in the end face of said barrel through a slot in the casing, rotation of the barrel to operate the mechanism preventing withdrawal of the lever. A casing 13, Fig. 7a, is secured to the lift cage and carries a pair of bolts 24, 14 which are adapted, when extended, to engage respectively. a slot in a projection 252 on the lift gate and the handing chain 11. The bolts are extended alternately against the action of springs 261, 21 by cam slots 152, 151 cut normal to one another in a rotatable barrel 15 having a slot 16 cut therein which, when the gate is unlocked and the handing chain is locked, is in alignment with a slot 17 in the casing. Through these aligned slots is passed an operating handle 19 (Fig. 2, not shown) which is locked therein when it has rotated the barrel 15 through 90 degrees to lock the gate and unlock the handing chain. Balls 22 and a spring 23 serve to locate the barrel in its position wherein slots 16, 17 are aligned. A pair of spring pressed chamfered jaws 27 are arranged to engage shoulders 1 on the bolts 24 if an attempt is made to shoot the bolt before the gate has been closed and a projection 252 on the gate has separated said jaws. In a modification (Figs. 1 and 2 not shown) bolt 14 only is used and the gate locking bolt 24 and its associated mechanism is dispensed with. Fig. 5 shows a landing gate lock of a construction similar to the above cage gate lock but modified to be unlocked only when a cage is at the landing, in which an arm 28 is pressed into a recess 242 in the bolt 24 by a spring 32 so locking the bolt and preventing it being actuated until after a wheel 30, connected to said arm 28, is engaged by a ramp 31 on the lift cage. A landing door lock, Fig. 8. has two bolts 35 which engage recesses in the floor and lintel when the door is closed and when so engaged allow the handle 19 to be inserted into a rotatable barrel through two aligned slots. On rotation of the handle the plate 34 withdraws the bolts which cannot be re-engaged whilst the door is open during which period also the handle 19 is locked in the barrel.
