Title: Method of storing and reproducing information
IPC: G06F11/14
Filed: 1965-10-07
Abstract: 1,136,212. Magnetic tape recording. J. S. THOMSON, and T. M. McCLURE. 6 Oct., 1966 [7 Oct., 1965], No. 19299/65. Heading G5R. A method of recording information on magnetic tape includes the provision of a number of carrier waves of different frequencies which are modulated in accordance with the information, and are then recorded consecutively on the same track of the tape. A method of retrieving information thus recorded includes distinguishing between the various carrier waves, demodulating them, and reproducing the information. The recording of computer information may be checked by a development of these methods, as described in the next paragraph. Carrier waves from a source 14 are modulated in a mixer 15 by computer information from a source 16. A change-over switch or flip-flop 17 has two outputs-one output passing the modulated carrier wave, (received from mixer 15), through an amplifier 18 to one gap of a twin head 19 for recording on one track, the other output passing, simultaneously, a complementary modulated carrier wave through an amplifier 23 to the other gap of head 19 for recording on the other track. Playback head 24 passes the signals from the tape to ganged tunable filters 25, 26, tuned to the carrier wave frequency, the outputs of which are amplified at 27 or 28 and summed at 29. Since the signals are complementary, the output of summing device 29 should be reasonably constant: a device 30 is therefore provided which initiates an alarm should the output from 29 fall below a predetermined level.

Title: Manufacture of ion exchange resins in spherical form
IPC: B01J47/00
Filed: 1958-06-17
Abstract: <PICT:0877935/IV (a)/1> Ion-exchange resins are made in the form of spherical particles by passing the starting materials in liquid or dissolved form from one or more supply containers, 1 via measuring and regulating devices, 3 to mixing and transport means 4, into an intensively stirred portion of a suspension medium shut off from the main body of suspension medium 9 by a screen 8 and kept at a temperature at which the drops into which the stream of resin-forming constituents is broken are hardened by condensation and/or polymerization before being continuously or intermittently discharged from the suspension medium.  The supply and feeding arrangements for each component may be independently heated or cooled.  In the example aqueous m-phenylene diamine hydrochloride is reacted with formaldehyde in a stirred suspension medium of turbine oil heated to 70 DEG C., and spherical particles of the resin are formed.ALSO:<PICT:0877935/III/1> To obtain ion-exchange resins in the form of spherical particles, the ingredients for making the resin are led from supply containers 1 by pipes 2, and measuring and regulating devices 3 to mixing and forwarding means 4 from which a stream of resinforming mixture passes into that intensively stirred portion of a suspension medium 9 which is contained within a screen 8. Here the resin-forming mixture is split into drops and the resin is formed and hardened as spherical particles which drop away into the relatively quiet portion of the suspension medium from which they are removed continuously or intermittently.

Title: Apparatus for testing the light-fastness of materials of all kinds
IPC: G01N17/00
Filed: 1951-08-20
Abstract: 691,239. Optical apparatus. VEREINIGTE FARBEREIEN AKT.-GES. Aug. 20, 1951 [Sept. 7, 1950; Nov. 28, 1950], No. 19631/51. Class 97 (i). Apparatus for testing the light fastness of materials, particularly textiles, comprises an optical system such as a condenser lens for concentrating sunlight without substantial variation of its spectrum combined to form a unit with a device for holding the material to be tested on the optical axis of the system, the unit being mounted so as to be universally pivoted to enable the optical axis to be directed towards the actual position of the sun. As shown, a stand 1 rotatably supports a vertical azimuth pivot 4 carrying a mounting 6 carrying a support 9 rotatable about a horizontal axis. The support 9 carries the hour spindle 10 of a heliostat driven by clockwork mechanism 11, the spindle 10 supporting a fork 14 in which is rotatable a declination shaft 15 which may be clamped by a screw 17. On the shaft 15 is a guide member 18 for two rods 19 on which slides a plate 20 bearing the condenser. In this case three condensers 21<SP>1</SP>, 21<SP>11</SP>, 21<SP>111</SP> are provided to illuminate a plate 22 on which the material to be tested together with a control strip, if desired, may be clipped.

Title: Improvements in or relating to methods of and apparatus for checking the alignment of shafts and other rotatable members
IPC: G01B5/24
Filed: 1957-06-21
Abstract: 828,479. Measuring axial misalignment. CENTRAL ELECTRICITY GENERATING BOARD, and CULLUICK, L. G. June 20, 1958 [June 21, 1957], No. 19668/57. Class 40 (1). The alignment of two shafts is checked by attaching members to the shafts or to coupling flanges carried thereon so that they overlap one another in the axial directions of the shafts, and measuring electrically the radial spacing of the members at two or more points along their length. By carrying out the measurements at three or more (preferably eight) angular positions of the shafts the axial and/or angular displacement of the shafts relative to one another can be determined and the bearings adjusted until they are accurately aligned. In Fig. 1 the coupling flanges 14, 15 of the two shafts 12, 13 (which may be part of a turbine and alternator respectively) carry magnetic clamps 20, 21 to which are attached the measuring members 22, 27. The member 22 carries three coils 24, 25, 26 and member 27 has three corresponding cores 28, 29, 30, so that the inductances of the coils will depend on the linear separation of the two members at the three positions along their length. The inductances are measured, preferably in a bridge circuit, and the separations thus estimated. With shaft 12 in a given angular position the other shaft 13 is rotated until the inductance of coil 24 is a maximum and the values of the three inductances then noted. These measurements are repeated for other angular positions of the first shaft, e.g. 45 degrees apart, and the results plotted on polar diagrams (Figs. 4, 5, not shown). The results for coil 25 show the eccentricity at the point where the shafts are to be coupled together, and the results for the other two coils show the angular misalignment. In a modification (Fig. 3, not shown) where the coupling flanges are very close together, the two members are clamped to the peripheries of the flanges and carry only two coils, one at the point of coupling and one on the other side of one flange.

Title: Improvements in railway car couplers
IPC: B61G3/04
Filed: 1925-08-10
Abstract: 252,576. Haddan, R., (McConway & Torley Co.). Aug. 10, 1925. Couplings, automatic; couplings, automatic convertible to non-automatic.-In an automatic coupling of the pivoted-knuckle type, the lock lifter 6, Fig. 1, is provided with a projection 17 adapted to engage under a shoulder 18 on the coupler head to prevent creeping of the lock, and the lifter and lock are operatively connected by trunnions 8 and slots 9 respectively for relative sliding and pivoted movements so that the lock is capable of being moved to unlocked position either from above or below the coupler head by the lifter and to swing over and be supported in the lock-set position, Fig. 4, by the knuckle 2 while the latter is in closed position. The lock 5 is provided on one side with a lug or projection 14, the lower end of which forms a lock-set leg adapted to rest, when the lock is raised, on a lock-set ledge 15, Fig. 2, on the knuckle tail, the ledge 15 tapering and extending only part of the way on the upper edge of the tail. The upper part of the projection 14 is flanged to overlap the tail of the knuckle to prevent the lock tilting forwardly until after the knuckle locking portion has been raised sufficiently to permit the knuckle to open. When the lock lifter 6 is raised it moves vertically upwards until the lower edge of the flat 20 enters the slot 9, the trunnions 8 then slide along the slot and withdraw the projection 17 from under the shoulder 18, the lock is then raised clear of the knuckle tail and is guided by the lug 14 in a groove 16 in the coupler head. When the lock 5 is clear of the knuckle it tilts, due to the fact that the trunnions 8 are at the end of the slots 9 so that the centre of gravity of the lock is to the rear of the trunnions and that the lock is bevelled at the part 11. The tilting of the lock enables the leg 14 to swing over and rest on the ledge 15 on the knuckle in the lock-set position of the coupling. Further upward movement of the lock lifter would cause a projection 25 on the lock to strike the short arm of the knuckle thrower 23 to open the coupling. If, when the lock is in lock-set position, the lifter 6 is released and the knuckle opened, the lug 14 slides off the ledge 15 and the lock falls so that its underside rests on the knuckle tail. A spring 27 may be used to prevent accidental closing of the knuckle, the ends of the spring engaging lugs 28, 29 on the knuckle and coupling head respectively. The knucklethrower 23 is mounted on a pivot 24, which may be cast with the head, and is prevented from sliding off the pin by a retaining wall 26 in the coupler head. The shoulder 18 may be a bar inserted in holes in the coupling head and be secured by a rivet or wedge. The slot 10 in the lock may be closed at the top and a hook or bollard may be made at the top of the coupler head for non-automatic coupling purposes.
