Patent GB-661032-A (GB)
Title: Improvements in or relating to synchronous-motor striking and/or chiming clocks
IPC: G04C21/06
Filed: 1948-12-01
Abstract: 661,032. Clocks. BROWN, T. A., and PERIVALE CLOCK MANUFACTURING CO., Ltd. Dec. 22, 1949 [Dec. 1, 1948], No. 31102/48. Class 139 A synchronous motor striking and/or chiming clock comprises a striking and/or chiming mechanism to be driven by said motor, a mainspring for driving the time train, an escapement mechanism to control the time train, a mechanism for winding the mainspring by the electric motor and means actuated by the time train for disconnecting the drive from the motor to the mainspring at the same time as it is applied to the striking and/or chiming mechanism and vice versa. The synchronous motor through gearing rotates a gear wheel 28, Figs. 2 and 5, which drives through gears 30, 31 two differential mechanisms 24, 25 associated with striking and chiming mechanisms respectively. The gear 30 carries the sun wheel 38, Fig. 5, of a differential the other sun wheel 41 of which is fixed to a gear 43 which drives a pinion 44 on a shaft 45 having a worm 46 with which a gear 47 meshes. The gear 47 is on a 'shaft 48 having a worm 49, Fig. 2, which drives a gear 55 on a sleeve 54 surrounding the minute spindle 50, Figs. 2 and 7. The inner end of a mainspring 52 is fixed to the sleeve 54 and the outer end slips in a barrel 53 connected to a ratchet 56 which co-operates with a pawl 58 to drive a gear 59. The mainspring is thus wound up by the synchronous motor through the differential mechanism, shown in Fig. 5, the planet carrier of which, Fig. 10, is normally arrested by the interengagement of the end of a pivoted arm 62 with a pin 61 of an arm 60 fixed to the planet carrier. When chiming or striking is to be effected a disc 65 allows downward movement of the lever 62 and the arm 60 and associated planet carrier are freed so that the drive from the synchronous motor to the mainspring is interrupted. Striking and/or chiming then takes place as described in Specification 489,855 upon movement by the time train of the arm 37, Fig. 2. The arm 60, Fig. 10, is again arrested after striking and/or chiming and the motor again winds the spring 52 which slips when fully wound. In another arrangement, Fig. 12, the pinion 55 is carried by a screwed sleeve 75 to which the inner end of the mainspring is fixed. The barrel 73 to which the outer end of the mainspring is fixed carries a pin 78 which engages a hole in a nut 77 which therefore moves from left to right as the mainspring is wound up and finally, when the mainspring is fully wound, engages an arm 79 carried by the lever 62 which is thereby moved to release the drive to the mainspring. In this case the cam 65 is shaped to raise the lever 62 to release the arm 60, Fig. 15, not shown, at striking and/or chiming. The mainspring may be initially wound by manual rotation of a gear segment 69, Fig. 2. The time keeping unit comprising the escapement and associated gears is removably attached to the back plate. Specifications 636,753 and 643,751 are referred to.

Title: Improvements in safe load indicators for cranes and the like
IPC: B66C23/90
Filed: 1935-11-12
Abstract: 467,494. Safe -- load indicators for cranes &c. WALLS, A. G. Nov. 12, 1935, No. 31233. [Class 78 (iv)] Safe - load indicators for cranes and the like are constructed to allow an excess of or an approach to the theoretical safe load which in amount varies inversely to the radius of working but is a constant percentage of the safe load at all radii. A third arm is geared either to the load-indicating or the radiusindicating arm so as to move faster or slower thereby progressively increasing or decreasing the angle between them, the variation being utilized to vary the time of giving a signal. In the form shown, the load-indicating arm 1 moves clockwise over the scale 2 while the safe-load radius-indicating arm 3 moves in the reverse direction from the other end of the scale as the radius increases. The third arm 8, which carries an electric contact adapted to complete a circuit by contacting with the arm 32 on the arm 1, is set back from the arm 3 at the lowest radius of working, but is geared thereto so as to rotate faster, thus bringing its overload line 10 more into coincidence with the actual safe load line 5 on the arm 3 as the radius of working increases. The hub 12 of the arm 3 is pinned adjustably to the shaft 4 by the set-screw 13. The shaft 4 drives the hollow hub member 21 through compound spur gear 14, 16, 17, 19. The arm 8 is fixed adjustably to the lid of the member 21, while a divided sleeve 26 clamped on the exterior carries the electric contact. The spur gearing may be replaced by any suitable reduction or accelerating mechanism such as ropes wound on drums of different diameters or a system of levers. The arm 8 may be set in advance of the arm 3 and move slower than the latter when the alarm is to be raised at less than safe load. Also the arm 8 may be geared to the load-indicating arm 1 and move slower than the latter to contact with an arm similar to 32 carried on the arm 3.

Abstract: 743,409. Colour television tubes. PHILCO CORPORATION. Dec. 11, 1952 [Dec. 11, 1951], No. 31392/52. Class 39 (1). [Also in Group XL (b)] A receiver tube for colour television comprising a number of colour triplets 32, 34, 36 of different coloured fluorescent materials covered with a reflecting layer 38 and indexing strips 40 is characterized in that the number of indexing strips is a fraction of the number of colour triplets. The fraction should be between 0.15 and 0.85 and is preferably where n is a whole number. The width of the strips is preferably equal to the distance between them. It is explained in the Specification that with this arrangement the frequencies generated by the indexing strips lie in a part of the spectrum separate from the video signals so that interference between the video signals and the indexing signals is reduced to a minimum. The strips may be secondary electronemissive and the tube may be provided with a wall coating to collect the secondary electrons; alternatively the strips may be fluorescent in the non-visible region and a photo-cell may be provided in a side-branch of the tube.

Abstract: 820,000. Radiolocation. STANDARDTELEPHONES & CABLES Ltd. Dec. 1, 1947 [Feb. 24 1945], No. 31692/47. Class 40 (7). In a radio position-determining system, a receiver is spaced from the transmitter and a reradiating object is employed to provide distance and angle measurements. Re-radiating objects 3, 4, 5, 6, which may be repeaters, are arranged in the field of a transmitter 1, Fig. 1, having a rotating antenna radiating short energy pulses. The receiver may be on an aircraft, and is also provided with a rotating antenna. This antenna 12, Fig. 2, is rotated at an angular velocity 50 to 100 times that of the transmitter. The received pulses are displayed at 15, directly received pulses at the centre 26 and re-radiated pulses from 3, 4, 5, 6 at 27, 28, 29, 30 respectively, their angular position indicating bearing and their radial displacement indicating difference in time between direct and indirect reception. A delay circuit 35 causes repetition of the direct pulse at 37 to indicate the bearing of transmitter. A further circuit 57 of variable delay regulates the gain of the intensity control 24, thereby brightening any spot having a required radial displacement. The angle # is determined from the display at 15A whereon 51, 52, 53, 54, 55 represent the relative angular displacement of the transmitter antenna when maximum signals are received direct and after re-radiation. In a modified arrangement, Figs. 4, 5 (not shown), an omnidirectional transmitter near 1 using a different frequency is employed to synchronize the rotary circuit 40 controlling the display 15A so that the true bearing of the receiver and of the objects 3-6 from the transmitter 1 is displayed. In further modifications, two spaced transmitters, omnidirectional (Fig. 6) or directive (Fig. 7), are employed in conjunction with a directive or omnidirectional receiver to provide data comprising bearings and the distance difference for the direct and indirect reception of pulses.

Title: Improvements in or relating to process for treating caustic aluminate liquor
Inventor: PORTER JOHN LEMOYNE
IPC: C01F7/473
Filed: 1953-11-19
Abstract: Sodium salts of organic acids (sodium organates) and sodium carbonate are removed from sodium aluminate liquors, usually obtained from low grade alumina ores, by concentrating the solution and separating the sludge which contains the sodium organates and most of the sodium carbonate.  In the Bayer process this treatment removes the substances which tend to inhibit the settling of the insoluble residues of aluminium ores.  The liquor may be concentrated so as to remove the sodium carbonate and sodium organates separately, but is usually concentrated to about 350 grams/litre of caustic soda.  The sludge is subsequently sintered with a material containing alumina, e.g. fresh ore or red mud residues from the alkaline digest in the Bayer process and is then leached with dilute caustic soda to obtain a sodium aluminate liquor which is recycled to the main process. Lime may be added to the sludge to prevent silicate formation during sintering.
