Title: Improved method of and means for cold-working steel bars to improve their strength
IPC: C21D7/10
Filed: 1953-02-25
Abstract: 726,562. Altering physical structure. TENTOR STEEL CO., Ltd. Feb. 25, 1953 [March 29, 1952], No. 5245/53. Class 83 (4). Twisting and stretching.-A method for improving the strength of steel bars, especially re-inforcing steel, by cold working by twisting or stretching or both during which the bar is held between two gripping devices is characterized in that the steel bar or bars wound around each other is or are, in the intervals between the cold-working, intermittently conveyed in the longitudinal direction to the treatment zone section, the bar or bars being conveyed to said zone through or along the one gripping device and being removed also in the longitudinal direction from said zone through or along the other gripping device. Steel bars welded together into long lengths and coiled on a drum 3 pass through straightening rolls 4 to a fixed stock 5 carrying a pneumatic or hydraulic gripping device 6 with adjustable jaws and through ring supports 7 to feed rolls 8 and thence to a sliding stock 9 having a rotatable grip 10 and then on to shears 12. After the cold working the bar is cut and feed rolls 13 convey the bar to adjustable automatic shears 14, 15 and 16 which cut the bar into predetermined lengths which fall into storage compartments 17, 18, 19 and 20. In operation, when the grippers 6 and 10 have gripped the bar the stock 9 is moved by chain or screw drive or by hydraulic means, to stretch the bar and either before, after or simultaneously with the stretching the grippers 10 are rotated by a motor 22 and belt drive 23 to twist the bar. After the stretching and twisting operation the grippers are opened and the feed rolls 8 push the cold worked steel through the stock 9 and pull fresh bar from the drum 3 into the machine. When the stock 9 has returned to its starting position the shears 12 cut the cold-worked bar which is then conveyed by the rolls 13 to the shears 14, 15 and 16 and cut into lengths. The drum 3 may be rotatable on two axes at right angles to each other and if desired instead of shearing the cold worked bar into lengths it may be coiled on a take-up drum similar to the drum 3.

Filed: 1942-04-22
Abstract: 559,076. Soap manufacture. SHARPLES CORPORATION. April 22, 1942, No. 5413. Convention date, April 23, 1941. [Class 91] Soap, preferably for re-cycling to succeeding soap-making batches, is separated from the nigre by purifying the latter by a treatment comprising adding thereto a source of acid so as to reduce in quantity or completely neutralize the free alkali of the nigre, and thereafter removing insoluble impurities from the treated nigre, such as by centrifuging. A source of acid signifies a free acid or an ester capable of furnishing an acid radical for combination with the free alkali of the nigre. The treated nigre is sufficiently heated to effect the neutralization. Soap-making fatty acids or the original fats are preferably used such as cocoanut, tallow, cottonseed, corn, palm kernel, and soya bean oils and rosin or the free fatty acids. The neutralizing treatment enhances the separation of the insoluble impurities which can then be removed. Other acids or esters may be used for the treatment, such as aliphatic and aromatic sulphonic acids, and hydrochloric acid. The acid-treated nigre may be diluted with water.

Title: Improvements relating to inverter circuits
Inventor: MERRETT John
IPC: H02M7/523
Filed: 1963-02-12
Abstract: 1,068,031. Semi-conductor oscillator circuits. HOOVER Ltd. April 2, 1964 [Feb. 12, 1963], No. 5749/63. Heading H3T. [Also in Division H2] An inverter circuit for supplying an inductive load comprises a pair of semiconductor controlled rectifiers (thyristors), connected in series between a pair of direct current supply terminals, a diode connected in parallel opposition with each controlled rectifier, a capacitor in series with the load terminals across one controlled rectifier, the controlled rectifiers being triggered alternately by signals derived from the load circuit. Fig. 1 shows a circuit for supplying power of the order of kilowatts to an induction cooking spiral 20 at 20 kc/s. Silicon controlled rectifiers 10, 11 and diodes 14, 15 are made sequentially conductive so as to generate a sinusoidal current in the oscillatory circuit formed by the capacitor 16 and the load 20. Triggering signals for the SCR's 10, 11 are ultimately derived from the voltage step at junction 36 caused by charge storage in each diode 14, 15 when the appropriate diode is turned off. The voltage steps at 36 are differentiated at 37 and 41, the negativegoing differentiated pulse being passed via diode 39 to trigger the left-hand blocking oscillator 25 which produces a positive pulse in winding 32 to trigger SCR11. The positivegoing differentiated pulse is used to trigger the right-hand blocking oscillator 25 which provides a pulse in winding 32 to trigger SCR10. Negative bias for the SCR's 10, 11 is provided by rectifying at 54 the outputs of a 10 kc/s. oscillator 51. The recovery time of each blocking oscillator 25 is reduced by capacitor 45 and diode 43. A capacitor (Fig. 2, not shown) may be connected between junctions 36 and 18 so as to form a ringing circuit at several times the output frequency which reduces the rate of rise of current when each SCR is turned on. The triggering of the SCR's may be delayed by including a differentiating circuit in each triggering lead so that the SCR's are triggered by the trailing edge of the pulse from the blocking oscillators 25. In Fig. 2 (not shown), the blocking oscillators 25. are triggered by pulses due to charge storage in diodes 14, 15 and derived by pulse transformers in series with the diodes. Starting oscillators.-The circuit shown in Fig. 1 is made self-starting by arranging the right-hand blocking oscillator 25 to be selfoscillatory. Alternatively, as shown in Fig. 4, a delay relay 70 may be used to discharge a capacitor 71 into an auxiliary winding 74 on one of the blocking oscillator transformers.

Abstract: 346,105. Twisting wires together. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., Hamilton House, Victoria Embankment, London, and RICHARDSON, A. B. F. G., of Callender's Cable & Construction Co., Belvedere, Kent. Feb. 22, 1930, No. 5899. [Class 83 (iv).] In apparatus for twisting wires together in pairs in sudden separate steps of twisting by stepwise rotary movements of a guide member for the wires the rotary movements are effected by a member such as a rack. segment or wheel moved slowly in one direction and then released and allowed to fly back quickly under the influence of a spring or other force. The apparatus is supported on a frame 10 attached to a wire-twinning or quadding machine 2 from which the wires of the pair to be twisted are brought from a pair of bobbins rotated in a frame so that before reaching the stepwise rotating guide the wires are given a uniform rotation about an axis. The frame 10 ends in a bearing block 11 engaging round a bearing 6 which turns freely within the block 11 and is held on the post between a collar 13 and washer 14. Bearing 6 is continuously rotated by a chain-wheel 8 and chain 17 passing around a chain-wheel 16 coaxial with the wires to be twisted and carries a crank 7 actuating a connecting rod 19 and crosshead 18 adapted to move freely between two guides 22, 23 within a slot 24 in a rack 25 with two sets of teeth 51, 52. A spring 36 pulls the rack to the left, the rack being guided by fixed blocks 30, 31. Crosshead 18 carries a catch 27 mounted on a spindle 26 and provided with a tail catch 29 such that when the crosshead reaches the limit of its travel to the left a spring 42 engages tail catch 29 causing catch 27 to engage a notch 43 in the wall 28 of the rack so that on movement of the crosshead to the right the rack moves to the right with it. At the end of the stroke tail catch 29 engages an adjustable stop 44 whereby catch 27 is released from notch 43 and the rack springs back and imparts a sudden rotation to pinions 53, 54 which drive through ratchet mechanism the guide members 70, 71 for producing the sudden twists in the wires. Two guide members 70, 71 are provided acting in opposite directions, one or the other being used according to the direction of the sudden twists, for which purpose the frame 10 may be locked with a set screw 56 engaging a part 57 for effecting right-hand twists by the pinion 54 or the frame may be rotated about part 1 and locked by screw 56 engaging part 60 for effecting left-hand twists by pinion 53. The guides 70, 71 are pinned at 72 to hollow members 62 driven from the pinions 53, 54 through ratchet teeth 73 ; other teeth 79 on the members 62 engage holding pawls to prevent backward movement of the members 62. Overrunning of the guide members 70, 71 is prevented by projections 82, 83 coacting with a spring- pressed stop 84 which is moved to engage the projections at the end of the working stroke by an incline 88 on the rack 25.
