Title: Improvements in or relating to record card controlled printing mechanisms
Filed: 1933-04-21
Abstract: 418,228. Statistical machines. BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, Southampton Row, London. April 21, 1933, No. 11716. Convention date, April 23,1932. [Class 106 (i).] In selective-printing mechanism wherein certain characters are represented by two holes in a column of a record-card, the type-member is normally stationary in a home position, and is associated with arresting-means under control of one of the holes, and with a movable controlling-member which, at a point in its travel determined by the other hole, is coupled to the type-member. In the apparatus shown in the Figure, type-bars 43, having alphabetical types arranged in groups of three between the numeral types 0-9, are provided with coupling-pawls 42 for engaging projections 9-0, 10, 11 on controlling-members 38 which are mounted on bars 39 on a cross-head 36 and are held in normal position by springs 40. The cross-head is connected to a cam-operated rock-shaft 33 so arranged that when the cross-head rises the projections on the controlling-members pass the coupling-pawls synchronously with the passage over the reading-brushes of the corresponding hole-position in the record-card. The projections 0, 10, 11 are spaced closely to compensate for slowing down of the cross-head at the end of its stroke. The coupling-pawls are normally restrained by latches 44 connected to the armatures 49 of magnets 46 in circuit with the reading-brushes. The type-bars are formed with teeth 58 for co-operating with pawls 57 co-operating with latches 56 which are connected to the armatures 54 of magnets 53 in circuit with the reading-brushes, commutators being provided for connecting these magnets to the reading-brushes only during the passage of hole positions 0, 10, 11 over the reading-brushes. If a character is represented by two holes, for instance 8 and 11, the type-bar is coupled to the associated controlling-member 38 when the 8 hole is read, and when the 11 hole is read the type-bar and controlling-member are arrested by the pawl 57 two tooth-spaces before the 8 type reaches the printing line, the character corresponding to the 8 and 11 holes being thereby positioned at the printing line. When a character is represented by a single hole 0, 10, or 11, the type-bars rise less than four toothspaces, the teeth do not co-operate with the pawls 57, and character-selection is effected by the projection 0, 10, or 11. Restoring-bails 67, 68 for the latches 56 and pawls 57 are connected to a rock-arm 63 in the path of an arm 61 on a shaft 60. When the cross-head descends, a bar 77 thereon returns the type-bars, and the pawls 42 are released by abutting on the latches 44, these having been restored by means of a bail 76 connected to a rock-arm 72 operated by a cam 71. The pawls 57 may be arranged to co-operate with teeth on the bars 38. Specification 247,200, [Class 106 (i)], is referred to.

Abstract: 878,367. Bladed turbine rotors. POICIT, R. April 15, 1958 [April 19, 1957; Jan. 15 1958], No. 12008/58. Class 110 (3). A gas-turbine rotor comprises discs 1a, 1b, the rim portions of which have radial slots 36 and form peripheral jaws 5a, 5b engaging the inclined heels 4a, 4b of the blade roots 9 and the similarlyshaped heels 29a, 29b of spacers 28 interposed between, and of complementary shape to, the blade roots, means such as screws and nuts 6, 6a being provided which keep the discs applied against each other in the axial direction so that the reaction between the jaws and the heels resiliently deforms the peripheral portions of the discs and holds the blade roots and spacers against one another in the circumferential direction. The rim portions may be integral with the discs (Figs. 1, 5) or may be formed on separate plates (Fig. 6) attached thereto, and are offset outwardly from the wheel body 1 so that the torque produced by the centrifugal force acting on them tends to increase the pressure of the jaws 5a, 5b on the heels. Each blade is made of metal, preferably of high thermal conductivity, and comprises front and rear portions 2a, 2b separated by an interval 8, the front portion having a thin layer 34 of protective material of low thermal conductivity and being surrounded by a sheet 11 of heatresistant material, such as nickel or a nickel alloy containing chromium, which overlaps the rear portion at its edges 11a, 11b and is gripped between the blade root and the adjacent spacers. Cooling air is fed to the interval 8 through a hole 10 (see Fig. 6) in the root and flows beneath the edges 11a, 11b of the sheet to issue as a laminar film over the surface of the rear portion of the blade. The cooling air, which is supplied through radial channels 20 and an annular chamber 19, is also fed to recesses such as 12-15 in the front portion of the blade beneath the sheet 11 and to radial channels 17, 18 within the front and rear portions. A shroud ring 25 (Fig. 1) is held by pins 26 (Fig. 5) carried by the blades, each pin having a base 26a which closes the end of an interval 8, and an annular spring 27 is interposed between the ring and the blades. Some of the recesses (12, 15) open laterally through notches in the sheet 11, and the other recesses (13, 14) and the channels 17, 18 open radially through holes in the spring and shroud ring, the air flowing from the front portion of the blade being projected in the form of a whirling ring. The outer surfaces of the spacers may be protected by sheets 32 of heat-resistant material, such as that used for the sheets 11, engaged between the heels and the jaws. In Fig. 6, the shroud ring 25 is tightly applied against the ends of the blades and cooling fluid which is supplied to a fixed chamber 41 upstream of the rotor leaks through a labyrinth seal 42 and circulates through grooves formed in the spacers under the plates 32, which have inlet and outlet apertures 43, 44 for this purpose. The cooling fluid may be recirculated by centrifugal action through divergent radial channels 45.
