Title: Paint base and its manufacture
Inventor: ETHERIDGE RALPH E
IPC: C09D7/80
Filed: 1954-05-06
Abstract: A liquid transparent base, free of active pigments and suitable for mixing with a liquid pigment concentrate to provide a paint having hiding power as described in Specification 789,161, comprises a dispersion of inert extenders in a film-forming vehicle and a solvent for the film-forming vehicle, the extenders being present in an amount of 22 to 56 per cent by weight, the film-forming vehicle being a resin or a long chain fatty oil and constituting 12 to 40 per cent by weight of the base, and the base having a pigment volume concentration of 20 to 62 per cent. Driers and anti-skinning agents are also preferably added.  The inert extenders are pigments or fillers having no hiding power, e.g. alkaline earth sulphates and carbonates such as calcium carbonate, "Calwhite," and diatomaceous earth and asbestine. The film-forming vehicles may be natural resins or drying oils such as linseed and soyabean oil.  The solvents may be terpenes, naphthas and petroleum solvents, that known under the name "Varsol" being exemplified.  As driers there may be used metal salts of fatty and resin acids and other metallic compounds, e.g. cobalt, calcium and lead naphthenates and aluminium stearate. Specified anti-skinning agents are guaiacol and methyl ethyl ketoxime.  Small amounts of lecithin are also included in the bases.  Examples are given of the formulation of the bases and of colour concentrates and of the final paints.ALSO:A liquid transparent base, free of active pigments and suitable for mixing with a liquid pigment concentrate to provide a paint having hiding power, as described in Specification 789,161, comprises a dispersion of inert extenders in a film-forming vehicle and a solvent for the film-forming vehicle, the extenders being present in an amount of 22 to 56 per cent by weight, the film-forming vehicle being a resin or a long-chain fatty oil and constituting 12 to 40 per cent by weight of the base, and the base having a pigment volume concentration of 20 to 62 per cent.

Title: Magnetic memory reading system
IPC: G11C7/02
Filed: 1954-05-06
Abstract: 753,272. Circuits employing bi-stable magnetic elements. RADIO CORPORATION OF AMERICA. May 6, 1954 [May 29, 1953], No. 13269/54. Class 40 (4). [Also in Group XIX] In a magnetic memory comprising a matrix of individually magnetizable elements identifiable as corresponding to elements arranged in rows and columns and row coils and column coils, each coupled to excite the elements corresponding to a different row and column respectively, thereby to drive to saturation only a selected matrix element, reading coils are each coupled to a different group of elements, each element in a group corresponding to an element of a different row and column from that of any other element in the group, whereby the matrix may be caused to excite only the reading coil which corresponds to the selected driven element. The 10 Î 10 matrix shown comprises toroidal cores 10 each coupled to a row coil 12, column coil 14 and reading coil 30, 32, 34, 36, 38, 40, 42, 44, 46 or 48. The rows and columns are selected by magnetic switches 20, 22 comprising further magnetic cores which are normally in an " N " saturation condition. If selected row and column switch cores are simultaneously driven to the opposite " P " condition, a selected core in the matrix is also driven to the " P " condition and, if it was originally in the " N " condition, a pulse is induced in the associated reading coil which drives from " N to P " a core 50 (having a coercive force less than that of the cores 10) of a magnetic register. For read-out, a pulse is applied from source 56 to a coil 52 coupled to all the cores 50; if a core is in condition " P," it will be restored to " N ", thus inducing an output pulse in a coil 54. The diagonal arrangement of the reading coils in relation to the cores 10 ensures that no coil has coupled thereto more than two of the cores which are half-driven by the selected row or column coil only. To further reduce unwanted signals, the reading coils may be coupled in opposite sense to cores on opposite sides of the matrix diagonal, as shown, and the output coil 54 may be coupled in opposite sense to adjacent cores 50. A writing schedule for the memory is described in which the output register is used for checking.

Title: Improvements in stationery feeding mechanism for addressing machines
Inventor: FLAWN PERCY ALFRED
IPC: B41L47/24
Filed: 1948-05-19
Abstract: 648,729. Addressing-machines; feeding webs. SMITH & SON, Ltd., W. H. May 19, 1948, No. 13582. [Classes 100 (i) and 100 (ii)] The feed-limiting one-way clutch device described in Specification 605,532, [Group XIX], is applied to mechanism for feeding marginally perforated continuous stationery beneath the rocking presser head of an addressing-machine, the driving member of the clutch being oscillated by or under control of the printing movements of the presser head. The mechanism may be incorporated in the addressing-machine, or, as shown, may be mounted on a separate frame 10, comprising two side-plates connected by cross-ties, clamped at 11 to the rear of the addressing-machine table 1; bearings in the side-plates are provided for shafts 16, 17 connected by a chain 19 and each carrying a pair of pin-wheels 18 engaging the stationery 15, and for a third shaft 20 carrying a gear 30 connected to the shaft 17 by an interchangeable gear train 21; a stop pawl 33 and a drive pawl 37 on a pivoted lever 36 engage the gapped annular ring 31 on the gear 30 as in the abovementioned Specification, the lever 36, spring- loaded at 47, being oscillated by a link 40 connected to a disc 42 whose pawl 46 engages a ratchet-wheel 45 driven through reduction gearing by a motor 44 energized through a mercury switch 53 tilted against a spring 56 by a pin 60 on a downward extension of the presser head rocking arm (not shown); the switch is closed on upward movement of the rocking arm for a period sufficient to cause the disc 42 to be driven anti-clockwise past deadcentre with respect to the link 40, whereupon the spring 47 returns the lever 36 to the position shown, the disc 42 over-running the ratchetwheel 45. For manual operation a second switch may be connected in parallel with the switch 53. The stationery 15, e.g. drawn from a zig-zag pack, passes under a spring-pressed idler roller 24 and is collected in a tray 26; superimposed strips of stationery may be fed at different speeds by providing above or below the shaft 17 a third pin-wheel shaft connected to the gear 30 by a different ratio train. In a modification the downward extension of the presser head may be mechanically connected by a link-and-lever system to the lever 36. According to the Provisional Specification, one of the links in this latter arrangement may comprise a toggle operated by a spring-pressed plunger to provide for manual operation, or a second lever corresponding to the lever 36 and on the other side of the gear 30 may be operated by the plunger, the gapped ring 31 being repeated and the stop pawl 33 being arranged to engage both rings; a manually-operated arcuate " cut-out " shield may also be provided between the pawl 37 and the ring 31.

Title: Improvements in automatic lifting dogs
Inventor: DAVIDSON ALEXANDER
IPC: B66C1/42
Filed: 1951-06-08
Abstract: 709,438. Lifting dogs with automatic control. BRITISH ELECTRICAL REPAIRS, Ltd. May 16, 1952 [June 8, 1951], No. 13609/51. Class 78 (4) Whether a pin g on an arm c of the lifting dog illustrated is trapped in a recess f in a locking bar a to prevent the dog closing after it has been opened is determined by the position of a ratchet wheel h turned about its pivot on the locking bar a each time the dog is raised. When the dog is open the pin g enters the end j of the recess f. When the dog is subsequently raised the pin engages one of four projections n on the ratchet wheel to turn it through 90 degrees. The ratchet wheel includes two surfaces k: if. when the dog is raised, the pin g engages one of these it is thrown out of the recess f as shown in Fig. 3. If, however, the pin g does not engage surface k it is allowed to enter the end m of the recess f to lock the dog in its open position as shown in Fig. 2. A spring biased pawl i engages the projections n to prevent reverse rotation of the ratchet wheel. Two such dogs may be carried by suitable lifting tackle and work in unison. Each arm b and c may comprise a pair of spaced parallel links riveted or otherwise secured together and between 'which the locking bar a and pin g are mounted.

Patent GB-928102-A (GB)
Title: Improvements relating to apparatus for soldering wire terminals to a printed circuitboard
Inventor: WALKER JOHN
IPC: B23K3/047
Filed: 1961-04-15
Abstract: 928,102. Soldering. FERRANTI Ltd. April 3, 1962 [April 15, 1961], No. 13661/61. Class 83 (4). An apparatus for soldering wire terminals to a printed circuit board includes a soldering iron movable along a vertical axis, means for projecting a beam of light to intercept said axis at a point, and means for moving said iron into engagement with a terminal positioned at that point and maintain it in contact for a predetermined time, after which a biasing means returns the iron to an upper position. In operation, an operator moves a printed circuit holder 40 on the machine table 2 until the light from a projector 37 falls on the terminal to be soldered, which is then positioned on the vertical axis 5a along which the iron 5 moves. The operator then lifts a weight 20 by means of a foot treadle (not shown) and a plunger 22, thus allowing the biasing means 10 to raise the iron 5, sleeve 3 and cylinder 13 to an upper position in which the piston 18 is also at its upper position in the cylinder 13. The sleeve 10, which carries the cylinder 13 on an arm 12, the iron 5 on an arm 4 and a lower retainer for the spring 10 on a band 11, is mounted on ball bearings and free to slide axially on a fixed pillar 1. The pillar 1 also carries a collar 7 on which is mounted an extension 9 for retaining the upper end of the spring 10. When the operator releases the weight 20, the piston 18 remains substantially at rest in the cylinder 13 while the entire sliding assembly descends against the action of the spring 10 until the soldering iron has descended past a strand 33 of cored solder (some of which it retains) and contacted the terminal 39 to be soldered. The piston 18 with the weight 20 continues to descend slowly in the now stationary cylinder 13 as air enters through an adjustable throttle valve 15, 16 until the piston clears a relatively large air inlet 17; the piston then descends rapidly to its initial position and since the weight 20 is no longer restraining the sliding assembly, the spring 10 abruptly withdraws the iron 5 from the soldered terminal. Solder is fed automatically through a tube 35 from a reel 34 by means of a pawl 28 which is actuated by a nut 31 carried on the sliding assembly. The apparatus may be modified by moving the iron into engagement with the terminal by means of a solenoid, the timing being determined by controlling the current supply to the solenoid. A further solenoid may be used to bias the sliding assembly upwardly.

As shown the knob 17, 21 rotates in a sleeve 41 so as to drive the shaft 13 of a television tuner 3 via gears 5, 7, 9 and 11. The scale 19 is driven from the shaft 13 of the tuner 3 via a square extension 25 which slides within a central sleeve 23 of the scale. A spring 27 enables the scale to be mounted between pivots 35, 37. The scale may be marked in television channels which are read against an index marked on the case 1. A U- shaped clip 52 locates the knob in the sleeve 41 which may be pushed into a support 43 formed as a part of the casing or a separate part mounted in the casing. A further U-shaped spring 45 secures the sleeve 41 in position but enables it to be withdrawn. The parts 17, 21, 41 may be of plastics material and the front 21 of the knob can be glued to the transparent part 17.
