Title: Improvements in and relating to the manufacture of prestressed reinforced concrete
IPC: B28B23/06
Filed: 1947-02-24
Abstract: 621,421. Pre-stressed reinforced concrete. BILLIG, K. Feb. 24, 1947, No. 5325. [Class 20(iv)] Concrete structures are precompressed by highly-tensioned bonded wires, the ends of which are embedded in a cast gripping block or blocks, the wires being stretched collectively in one or several groups by moving the blocks. The wires are afterwards cut and the gripping blocks, e.g. of rapid-hardening concrete or lead or lead alloy, are removed. In the form shown, the reinforcing wires 31 of a concrete unit 32 pass through deflecting plates 37 into the concrete gripping block 36. The wires are spot-welded to a steel pattern 38 and their initial length and tension is adjusted before the block 36 is cast. The blocks are moved to tension the wires by means of jacks 34 bearing on anchorages 33 and acting on a frame 35 which may be integral with the block. In another form, a smaller block is used in which the wires converge, and the block is gripped by steel jaws connected to a hook which is pulled by a jack. Where the blocks are of a lead alloy (the composition of a suitable alloy is described) the wires are coated with tin or a tin alloy to improve the bond between the blocks and the wires. The wires may be twin or triple-twisted. A number of concrete units may be placed in one stretching line with one gripping block at each end of the line.

Abstract: 539,947. Felt hat body forming apparatus. LEE CO., F. H. March 29. 1940, No. 5678. Convention date, March 30, 1939. [Class 63] [Also in Group IX] An automatic machine for forming felt hat bodies, each from a weighed quantity of fur, comprises improved weighing and feeding mechanism applied to the forming machine described in Specification 523,453, the whole being controlled electrically by a cam assembly on the rotor of an electric motor. Fur contained in a hopper 2 is lifted by barbs 8 on an endless apron 4, levelled by barbs on a rotor 10, compacted by resilient fingers 14, and removed from the apron by barbs on a rapidly rotating wooden roller 16 to fall into a hopper 20. The hopper has dumping doors normally held up by a latch, and has a balance weight, the supporting arm having prongs dipping into mercury in cups 562 to complete an electric circuit. On the arm beginning to tilt, this circuit is broken, a solenoid then changing gears to reduce the speed of feed. When a beam from a spot light 17 normally directed on a photo-electric cell 19 is blocked by the arm a solenoid releases the latch and the fur is dumped on to an endless belt 24. A baffle 26 is swung under the roll 16 as the dumping doors open. The felt 24 co-operates with a presser roll 28 and feed rolls 30. A rapidly rotating picker 34 produces an upward air current in a casing 32 having an adjustable intake at its lower end. The upper end of the casing is closed by rotating perforated rolls which carry the fur to a roll 42 delivering to a pair of feed rollers 44 delivering to a top picker 46 and a roller 48 the fur passing in a cloud to a cone 54. This cone forms one of a pair alternately moved into the forming tower and out through swing doors to spraying apparatus, the cone being then inverted for the removal of the bat, this apparatus being substantially the same as that described in the prior Specification. While the cone in the forming tower is being charged the sieve rollers 38, 40 are stopped. A suitable electric control circuit comprises a number of switches operated in sequence by the rotor of an electric motor, the rotor having a brake operated by a solenoid for stopping the apparatus. The cycle of each of the cones is completed in two cycles of the fur feeding mechanism. The rack described in the prior Specification as swinging the cones is connected to a pair of ganged switches conditioning the various circuits to actuate the appropriate cone. Delay switches are interposed where necessary, and manual switches, most of the switches being actuated by solenoids. The circuit is described in detail.
