Title: Improvements in machines for manufacturing metallic network
IPC: B21F27/10
Filed: 1935-08-20
Abstract: 461,640. Making wire fabrics. JOHNSON'S REINFORCED CONCRETE ENGINEERING CO., Ltd., TAYLOR, B., and MEACHER, W. Aug. 20, 1935, No. 23397. [Classes 83 (ii) and 83 (iv)] Welding.-In a machine for making metal fabrics, particularly for reinforced concrete, comprising longitudinal and transverse wires or rods joined, e.g. by welding at their points of crossing, and of the type having locating members for positioning the transverse wires at the joining station and means for feeding the fabric forwards the desired amount after each joining operation, one or more of the locating members constitute also reciprocating feeders. The longitudinal wires 10 pass from drums through straighteners and then through holes in a bar 11, secured to standards 12. The transverse wires 16 are dropped from a shoot 50, either automatically or by hand, over fingers 15 which position them between welding electrodes 13. The fingers are mounted on a rock-shaft 14 and are normally held in the position shown by springs 17 through levers 18. The transverse wires during welding are held in position by blades 20 on a shaft 19 which carries a handle 21, the blades being controlled by snap-over springs 22. Co-operating with the fingers to position the wire 16 are hooks 49 secured to a triangular frame-like table 23, which is reciprocated to feed the fabric through the machine. The table may be mounted on pivoted legs 24, 25 and is moved forward against the action of a spring 38 by cams 33 on a shaft 32 driven continuously by spur gear from the main shaft 28. Alternatively the table may be connected to the legs by a pin-and-slot and may be reciprocated in guides. The cams engage followers 36 on arms 35, which are pivoted at 34 to the legs 24 and are moved by a handle 37 out of contact with the cams so as to stop the feed during the welding operation. When the feed is to be effected the arms 35 are moved on their pivots and held in position by teeth 45 on the resilient limbs of locking members 41 engaging notches 46. During feeding of the fabrics the transverse wire first pushes down the fingers 15 and finally engages hooks 53 on a bar 51 pivoted at 52 so as to trip the hooks which drop back by gravity so as to prevent backward movement of the fabric. On the return movement of the table adjustable screws 43 on the locking members engage stops 44 to free the arms 35 and so disconnect the feed mechanism. In order to vary the spacing, the table may be provided with adjustable stops 56 to vary the stroke of the table, the hooks 49 being adjustably mounted on the table to set them in correct position. The blades 20 and lever 37 may also be operated automatically.

Title: Screw thread system
IPC: F16B33/02
Filed: 1964-06-05
Abstract: 1,072,578. Rolling threads; taps. STANDARD PRESSED STEEL CO. June 5, 1964 [June 6, 1963], No. 23472/64. Headings B3M and B3N. [Also in Division F2] Fatigue life of mating screw-threaded components is increased by (a) relieving the pressure flank 19 of the external thread so that no flank contact occurs from the root to at least the pitch line 14 of the internal thread; (b)forming the internal thread with a progressively longer lead than that of the external thread when unloaded; and (c) correcting the true pitch diameterof either or both threads to prevent interference when unloaded. Under load, thread deflection causes the differential lead to be absorbed into full length contact. Features (b) and (c) form the subject-matter of Specification 1,032,814. In -Fig. 1, the internal thread flanks are straight and conventional. The external flanks are symmetrical-involute and the radius 19 of the above-pitch-line relief is four times thread height, the root radius 18 being twice thread height. An asymmetrical external thread, Fig. 2, not shown, has an unloaded flank which is straight and parallel to the adjacent internal flank. In Fig. 4, not shown, both thread forms are conventional but the internal thread has a flank angle of 60 degrees, the external 64-70 degrees. The internal threads are cut by a tap (Fig. 8, not shown), whilst the external threads are rolled by flat dies (Figs. 5 and 6, not shown) or cylindrical dies (Fig. 7, not shown), having ribs complementary to the required external thread profile.

Title: Process for the manufacture of a subtractive colour film
IPC: G03F3/08
Filed: 1955-08-15
Abstract: 791,675. Copying by scanning. GRETENER, E. Aug. 15, 1955 [Aug. 16, 1954], No. 23489/55. Drawings to Specification. Class 40 (3). In an arrangement for producing a colour motion-picture film, sets of electrical signals individually representative of three component colours in an original are derived by a scanning process and from each of these sets of signals four further sets of signals individually representative of the grey content (brightness) and of the colour residues are derived (e.g. in the manner described in Specification 737,212 and U.S.A. Specification 2,316,581), the grey content signals being recorded on a black/white sensitive layer and the colour residues on colour sensitive layers. This arrangement avoids distortions inherent in conventional subtractive colour recordings (due to overlap of the spectral absorption curves of the subtractive dyes) by representing the brightness variations of the colours by a neutral-tone (grey-content) and the colour (of each image element) by the superimposition of two substractive dyes, the amounts of the latter being independent of the brightness of the colour.
