Title: Number translators
IPC: H04Q3/00
Filed: 1962-11-30
Abstract: 1,025,251. Automatic exchange systems. HITACHI SEISAKUSHO KABUSHIKI KAISHA. Nov. 30, 1962 [Dec. 5, 1961], No. 45450/62. Heading H4K. The output of a translator is arranged to be different in accordance with the free or engaged condition of equipment represented by the translated number. As shown, two-digit directory numbers determine the column and row of a core in matrix I, the appropriate core turning over when a row and column conductor is energized to transmit a pulse over circuit c. Cores in matrix II are in residual states a or # according as the equipment associated therewith is busy or free. In the latter case the direction of the pulse in c is such as to turn the core over to state # thereby causing the equipment code to be emitted as a pulse over one horizontal and one vertical conductor of the matrix. The turning over also pulses a wire ib common to all cores to indicate that the equipment was free. If the core is in busy state # no pulse is emitted over the horizontal and vertical wires nor in the wire ib. Arrangements for changing the state of the cores of matrix II independent of those just described may also be incorporated.

Abstract: 1522849 Photometer MEDICAL & ELECTRICAL INSTRUMENTATION CO Ltd 27 Sept 1976 [3 Nov 1975] 45654/75 Heading G1A [Also in Division G2] Photometric apparatus comprises a logarithmic photosensor unit 10, 14, 16, switch 53 for applying a signal dependent on the photosensor unit output to store 35 at the input of memory circuit 34 and to a read-out including summing amplifier 32 with indicator 33, and switch S4 for applying a signal from store 35 to it in opposition. In the colour analyzer of Fig. 1, the four position filter selector Sl is mechanically coupled to switches S1A, S1B and S1C. The detector output is compared with an adjustable reference from unit 25 by summing amplifier 22. S1 is first set so that the 'open filter' is selected and an iris on source 19 adjusted to zero indicator 33. Red, green and blue filters are selected in turn by Sl and respective resistors 26, 27, 28, 29 adjusted to zero indicator 33. Then S1 is set to the colour of the highest density and the output from amplifier 22 stored by momentarily closing S 3 . With S4 closed and Sl selecting another colour filter, indicator 33 displays the sum of the actual and stored signals, and the light intensity of the selected colour may be adjusted so that it reads zero.

Abstract: 1,188,100. Fluid operated motors. DINGLERWERKE A. G. Oct. 1, 1968 [Oct. 7, 1967], No.46529/68. Heading F1P. A fluid operated motor for varying the pitch of a ship's propeller of a blower impeller comprises a piston 3 in a cylinder 1, the piston having on its periphery, oppositely directed conical washers 5 arranged to lock the piston to the cylinder in the absence of a pressure differential across the piston. The conical washers carry cylinder wall engaging braking shoes 6 on their outer peripheries and are held in the piston 3 by a spacer 7. Each conical washer 5 resists movement in one direction by tending the flatten when the cylinder attempts to move relative to the fixed piston. When pressure is applied to chamber a or chamber b thereby to re-position the cylinder, an end plate 2 in that chamber is forced into abutment with the adjacent washer to deflect it radially inwards and thus nullify its locking action. Since the other washer only exhibits locking action in the other direction, the cylinder is moved. The piston and cylinder may rotate with the piston rod 8.

Abstract: 1358716 Alumina powder composition P A TSEITLIN T A DERBENEVA G M ZVEREV and F M ZUBKOVA 8 Oct 1971 46920/71 Heading C1A A single crystal of corundum is grown from a powder including 74-99% by weight aluminium oxide, from 0-6% by weight metallic colouring substance and from 1-20% by weight aluminium fluoride. The powder may be prepared by calcining a mixture containing aluminium hydroxide and from 0-7% by weight of a metallic colouring substance at 1100-1200‹ C. to form a powder containing at least 80 wt. per cent α-aluminium oxide, metallic substance if present being incorporated into α-Al 2 O 3  lattice and mixing the calcined mixture with 1-20 wt. per cent AlF 3 . In Example 1, aluminium hydroxide (containing Al 2 O 3  100 g.) and 0À5 wt. per cent chromium (calculated with respect to Al 2 O 3 ) is calcined at 1150‹ C. for 2 hours, the obtained powder (70 g.) being below 60 Á being mixed with AlF 3  (7À8 g.). The similar preparation of powders containing Ti and Fe is described in Examples 2 and 3. The powder may also be prepared by calcining the hydroxide, 0-7 wt. per cent colouring substance and 5-20 wt. per cent AlF 3  or NH 4 F (calculated with reference to AlF 3 ) at 1050‹ to 1150‹ C. to form at least 80 wt. per cent α-aluminium oxide and again mixing the calcined mixture with AlF 3 . In Example 5 aluminium hydroxide containing Al 2 O 3  (100 g.), chromium (1 wt. per cent) and ammonium fluoride (20 wt. per cent) with respect to AlF 3  is calcined at 1050‹ C. Example 6 describes the use of powder containing γ-Al 2 O 3  (derived from alum) and chromium for growing crystals. Other colouring substances specified are nickel, vanadium and cobalt. Corundum crystals (e.g. ruby, lilac coloured and blue sapphire) may be grown from the powder by the "Verneuil" method.

Abstract: 1,091,225. Machine for making swabs. DR. CARL HAHN KOMM-GES. Oct. 20, 1966, No. 47018/66. Heading A5R. A machine for the manufacture of swabs by providing fibrous material 46 on the ends of small sticks comprises a wheel 18 for transporting the sticks 21 to a place for applying the fibrous material, there being provided on the periphery of the wheel pairs of rollers 35 each rotating in the same direction and adapted for rotating the sticks about their longitudinal axes while they are transported. As shown, the machine includes a device 22 feeding the sticks to the pairs of rotating rollers 35, wheels 63 (36) applying adhesive to each end of each stick, a device (see also Figures 6, 7, not shown) including rollers 47, 48 (41, 42) which separates the fibrous material into tufts, sponges 78 supplied with water and used to dampen the swabs, and a conveyor 81 removing the swabs, The fibrous material may be cotton, rayon, artificial fibres, or a mixture of these, and the machine also includes a switch 40 (38) which switches off the machine when the supply of sticks to the wheel 18 fails. The wheel 18 is in two parts separated by a fixed toothed wheel 74 and, as the wheel 18 rotates, cogs 73 fixed to the rollers 35 are moved with the wheel 18 and are rotated against the fixed wheel 74. The device providing the tufts of fibrous material to the machine comprises (see also Figures 6, 7, not shown) two pairs of intermittently rotating rollers (41, 42) and two pairs of continuously rotating rollers 47, 48, the rollers (41) 47 being intermittently driven from the main drive shaft of the machine through a chain (61) and an electro magnetic brake device. Shaped channel members 76, 77 (see also Figure 11, not shown) form the tufts on the rotating sticks to the required shape and retain the swabs on the wheel 18 until they are removed at the conveyor 81.

Abstract: 1279447 Fuel elements GENERAL ELECTRIC CO 25 Sept 1969 [26 Sept 1968] 47295/69 Heading G6C A fuel assembly comprises a plurality of spaced, elongate fuel elements, a member containing burnable poison being provided within the assembly, the nuclear fuel of the fuel elements comprising an initial first fissile fuel and an initial second fissile fuel having greater fission cross-section than the first fissile fuel, the second fissile fuel being preferentially concentrated in at least the parts of the fuel elements adjacent the burnable poison, and the first fissile fuel being preferentially concentrated in at least some other parts of the fuel elements. Such a fuel assembly comprising spaced, parallel fuel rods 12 has the burnable poison in one of these fuel rods, viz. fuel rod 12<SP>1</SP>, and Pu-containing fuel in those fuel rods 12<SP>11</SP> surrounding the fuel rod 12<SP>1</SP> where the Pu will be within one neutron diffusion length of the burnable poison. The remainder of the fuel is U. Because of its greater fission cross-section, the initial power density in the Pu-containing fuel tends to be greater than in the U fuel, which helps to overcome the initial depressive effect of the adjacent burnable poison. Furthermore, the greater absorption cross-section of Pu causes it to deplete more rapidly than U which aids in preventing power peaking later in the fuel cycle. Satisfactory results are obtained when the fuel rods 12<SP>11</SP> contain about 1À2 atom per cent fissile Pu and 1À8 atom per cent fissile U. Where the fuel rod 12<SP>1</SP> contains the burnable poison only in one particular axial zone, then the Pu need be contained only in the same axial zone of the fuel rods 12<SP>11</SP>.
