Title: Improvements in record-controlled printing machines
Filed: 1957-01-22
Abstract: 844,526. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 22, 1957 [Jan. 25, 1956], No. 2234/57. Class 100(4) A punched card controlled typewriter having a type-wheel positioned by a magnetically controlled clutch has improved electrical card sensing means in which brushes sense holes in a card to select groups of type. Individual type are selected on sensing further holes. Also, additional groups of type are selected when certain combinations of holes (i.e. 8-4 and 8-3) are serially sensed. Cards 10, Fig. 1, having twelve punching positions per column are used, and twelve brushes 19, statically read record holes 12, (R), 11, (X), O, 1-9 in a column. Impulses are transmitted to related sensing brushes in the order 9-1, O, X, (11), and R, (12) as a brush wipes over the emitter contact points. Groups of type, Fig. 4, are selected by impulses 8-4, 8-3, completed serially through the two appropriate holes, and 9-0. An individual type in a group is selected by the second O, X or R impulse for a letter or the N impulse for a digit. A printing control magnet 26, Fig. 3, when energised by an impulse through a hole initiates the differential anticlockwise rotation of a type wheel 25 through members 28, 27, 29, 31, 32, arms 37 and members 39, a clutch pawl 55, a fluted tube 41, and gears 43. An armature knock-off cam 75 prevents an armature 28 from sticking, through members 76, 78, 79, 27. A clutch release arm 39 is returned to pawl engaging position, as in Fig. 3, by a finger 82 moved by a cam and follower 86, 85, 84. A second impulse to a magnet 26 from zone holes O, X, R, or from the N impulse generating cam selects a character from a group by engaging the printing clutch 98, 99 through members 28, 27, 79, 78, 77, 91 and pawl 94. As a cam 65 revolves, projection 63 engages projection 62 and rocks a frame 60 pivoted at 61 and a type-wheel 25 towards a platen 67 to print. A cam 95 prevents this sequence occurring in response to the first impulse to the magnet 26. The type wheel 25 rotates more slowly during character selection from a group as described in Specification 605,132. Brushes 114-117, Fig. 5, rotate half a revolution per machine cycle. The circuit through magnet 26 is completed as follows:- Positive line 120, segment 112, brush 116, wire 122, brush 117, 8-4 or 8-3, wires 123, 129, hole 8, brush 19, plate 11, brush 19, through either hole 4 or 3, and either wires 130, 131 to 8-4 or 132, 133 to 8-3, from either of these through brush 114, wire 126, brush 115, segment 113, wires 107, 106, 105 and magnet 26 to negative line 121, and similarly for points 9-1, O, X and R. The N impulse is transmitted under control of CR1 cam contacts. Specification 632,724 also is referred to.

Title: Improvements in or relating to Fluid Coupled Ultrasonic Transducer Units
IPC: G01N29/28
Filed: 1967-01-17
Abstract: 1,168,881. Ultrasonic wave couplings. MAGNAFLUX CORP. 17 Jan., 1967 [27 May, 1966], No. 2533/67. Heading H4J. An ultrasonic transducer unit for testing a part 12 having a surface 20 of predetermined configuration comprises a hollow, preferably cylindrical, casing 16 having an inlet 15 for connection to a pressurized liquid source and having an end wall 18 with a single opening 26 therein. An ultrasonic transducer 28 (preferably piezoelectric) transmits and receives ultrasonic waves through the opening 26. The end wall 18 has a surface 19 placeable in generally parallel uniformly spaced relation to the part 12. The opening 26 is central of the wall 18 to provide a liquid flow path from within the casing 16 through the opening 26 to the periphery of the wall 18. A stable dynamic pressure effect and a stable static pressure effect are distributed over the flow path to maintain the surfaces 19 and 20 spaced. Rapid relative movement between the unit and the part 12 is possible and hot product (e.g. 700-800‹ F. or higher) may be tested. The wall 18 has a circular flange 27 to increase the flow path. The surface 19 may be concave to correspond to the outer cylindrical surface of a pipe under test. The piezoelectric transducer 28 has a back face 30 cemented to a block 31 of ultrasonic wave-absorptive material. The block 31 is within a cylindrical metal housing 32 which carries a coaxial connection 33 threaded on to a mounting member 34 provided with flow passages 42. To prevent improper indications due to multiple reflections the distance d from the front surface of transducer 28 to the surface 20 divided by the velocity of sound in the liquid coupling is substantially greater than the thickness t of the part 12 divided by the velocity of sound in the part 12. The wall 18 has a tapered surface 49 to prevent direct reflection back to the transducer 28.
Patent GB-679015-A (GB)
Title: A new or improved elastic fabric
IPC: D03D15/56
Filed: 1949-01-31
Abstract: A method of making an elastic fabric includes incorporating in the fabric elastic threads in parallel relationship with textile threads which each comprise at least one thread of inextensible textile material wrapped around a chemically removable core, and treating the fabric to remove the cores of the textile threads. The elastic threads may be incorporated in an unstretched condition by associating them with inextensible threads of a material removable or destructable as by chemical means. Alternatively the elastic threads may be incorporated in a predetermined condition of stretch, for example by being stretched and having applied whilst in the stretched condition a helical wrapping of textile thread to maintain the stretched condition, and a further wrapping of a chemically removable inextensible thread to inhibit further stretch.  Desirably the inextensible threads associated with the elastic threads and the core material of the non-elastic threads are removable by the same means, for example, they may both comprise alginate threads and be removed by the same solvent.  Specifications 291,998, [Class 120 (iii)], 517,978 and 678,507, [both in Group IX], are referred to.

Abstract: 871,781. Punching; stamping; sub-press mechanisms. DESOUTTER BROS. Ltd. Jan. 25, 1960, No. 2672/60. Class 83 (4). A press tool set comprising a base 1, two or more parallel pillars 2, 3 upon the base, a punch holder 5 having a corresponding number of bores therein, each provided with a bush 7, for receiving said pillars is characterized in that each bush is positioned and held in the punch holder bore by being provided with an external U-shaped circumferential groove 8 and a key 9 which engages closely in said groove at one end and is held at its other end upon the punch holder in such manner as to urge the latter in a direction parallel to the axis of the bush, thereby causing the key to make firm contact simultaneously with both opposite faces of the said groove. In an embodiment, a pair of keys 9 are fastened to the punch holder by headed screws 10. The keys are initially shaped so as not to lie wholly in one plane as shown in Fig. 5, so that on tightening the screws the keys are distorted to lie in one plane, Fig. 6, with the result that pressure is exerted on the opposite faces of the groove as shown by arrows A and B to effectively lock the bush in position and ensure an accurate alignment. Alternatively, initially flat keys may be used whereupon the parts of the punch holder adjacent the bush are shaped to distort the keys the desired amount on assembly.
