Title: A new or improved method of and apparatus for processing wire and the like
Inventor: HANN KENNETH GRAEME
IPC: B21F9/00
Filed: 1967-02-24
Abstract: 1,208,274. Stretching; shearing; working at specified temperatures. G.K.N. SOMERSET WIRE Ltd. 21 Feb., 1968 [24 Feb., 1967], No. 8809/67. Headings B3E, B3V and B3W. A method of effecting permanent elongation to increase the creep resistance of a metal element, e.g. wire, strand, rope, comprises passing the element under tension around not more than three rotary members 15, 16, rotating at the same angular velocity and having peripheral V-grooves 28, 29, which progressively increase in diameter in the direction of element advancement and the angle between the sides of which is not more than 30 degrees, the element being heated at 35 prior to passing to the largest diameter V-groove 29. The angle between the sides of the V-grooves may be varied by packing strips (30) (Fig. 3, not shown). Wire 37 is fed from a supply reel 38 or 39 to a brake wheel 40, from which it is led to the groove 28 of the rotary member 15 under appreciable tension. After leaving the rotary member 15, the wire is led around an idle wheel 31 and through an induction heater 35 where the carbon steel wire is heated to 220-500‹ C. If the wire is an alloy steel, it is heated to 600‹ C. The wire is thereafter cooled in a water bath 36 and led into the V-groove 29 of rotary member 16, from which it is pulled under tension by pairs of wheels 43 having rubber tyres 44. The upper of the two wheels 43 in each pair is mounted in a pivoted arm (80) (Fig. 5, not shown) to permit passage of enlargements on the wire at a joint between lengths of wire. The wire is finally wound on a reel 55 or 56 and is cut by a device 47 when the reel is full. The wire is cut by displacing a valve (69) (Fig. 6, not shown) to pressurize a ram (60a) in a cylinder (60) and manually displacing a detent member (64) into the release position to cause a piston-rod 61, Fig. 7, connected to the ram (60a), to move forward. A die 52 is reciprocated by movement of the piston-rod 61 to cause the wire 37 to be sheared, the free end of the wire in the die 52 being directed to an adjacent hole 51 in a stationary die 49, from where the wire is led to the empty reel 56. An identical cylinder (59) is positioned on the opposite side of the die 52 and is connected to a low pressure pipe (72) during reciprocation of the piston-rod 61 so as not to resist movement of the die 52. When the reel 56 has been filled, the valve (69) is reversed and a detent member (63) moved into the release position to cause a piston-rod (61) to move the die 52 in the opposite direction. Idle wheel 31 may be replaced by a further rotary member, which is connected by gearing to the other two rotary members. The permanent elongation effected may be 2-5%.

Title: Improvements in and relating to the manufacture of heating oils and internal combustion engine fuel oils
IPC: C10L1/08
Filed: 1937-03-25
Abstract: Diesel and heating oils consisting of solutions of primary bitumen or of coal extract in an oil poor in hydrogen are rendered stable by adding an oil causing precipitation of the substances of high molecular weight which are at or near the solubility limit, removing the precipitate, as by filtration or centrifuging and then removing the precipitating oil, as by distillation. Precipitating oils specified are benzine, benzene, light oils produced by hydrogenating coal extracts or primary bitumens, and oil fractions of a paraffin base rich in hydrogen, e.g. those made in the Fischer-Tropsch CO-H2 synthesis.  The precipitated substances may be further hydrogenated or may be used in the hydrogenating process for the manufacture of solvent oil from coal extract.  In an example, a primary bitumen is obtained by treating coal with a deficiency of hydrogen in presence of a solvent; this bitumen is hydrogenated to obtain a light oil boiling below 220 DEG  C. and a middle oil B.P. 200-400 DEG  C. relatively poor in hydrogen. 35 lb. of the bitumen is dissolved in 65 lb. of the middle oil, and after heating to 80 DEG  C. 20 lb. of a fraction boiling below 200 DEG  C. of the light oil is mixed in; 8 lb. of oily matter is precipitated, stirred together, and filtered off; the light oil is then distilled off leaving a stabilized Diesel fuel oil.

Abstract: 1,014,257. Magnetic erasing heads. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 3, 1964 [March 6, 1963], No. 8950/64. Heading G5R. An erase head with a reduced stray field at the side 5, Fig. 1, arises from stepping the core at the gap 3. The field at 4 is necessarily larger than that at 5, so that by the time the field 4 is reduced to the level normally found on a conventional head as at 5, the field at 5 is reduced in proportion. The preferred embodiment, Fig. 5, has ferrite pole-pieces, Fig. 6, such that the plane 14 is preferably square, so that on assembly the tapeguiding face to be ground has a uniform width across the gap. The reduced stray field allows this side of the head to be placed closer to another track which is not to be erased. A two-track embodiment is also described, using Fig. 5-type elements (Fig. 7, not shown).

Title: Improvements in or relating to transistor amplifiers
Inventor: RALPHS JOHN DENNIS
IPC: H03F1/30
Filed: 1960-03-15
Abstract: 902,430. Transistor amplifier circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 23, 1961 [March 15, 1960], No. 9084/60. Class 40 (6). An amplifier comprises a transistor having the input signal applied to its base and a resistancecapacitance smoothing circuit connected to the emitter, pulses being applied to the transistor to urge it to conduct, resulting output pulses being amplified and used to cause the transistor to charge the smoothing circuit in a sense to cutoff the transistor. If an input voltage is applied to terminal A 1 , pulses applied to the emitter of transistor Q 1  through a transformer T 1  will cause the transistor to conduct. The resulting output current pulses in a transformer T 2  cause a transistor Q 2  to conduct and so charge the smoothing circuit in a direction to prevent transistor A 1  from conducting. The rate of charging diminishing at successive pulses until the amount of charge added to the circuit only balances that lost between the pulses. The output terminals A3, A4 accordingly supply a voltage substantially equal to the input voltage, the input impedance of the amplifier being high and the output impedance low. A capacitor C 2  causes the transformer to ring so that the transistor Q 2  conducts during two or three successive peaks in response to the input pulses. The pulses applied to T 1  may alternatively be fed in opposite phase to the base of transistor Q 1  instead of to the emitter. In an alternative circuit (Fig. 2, not shown) an emitter follower is interposed between transformer T 2  and transistor Q 2  and the output signal is obtained from a further smoothing circuit in the emitter lead of a transistor fed with pulses from an additional winding on transformer T 2 . The pulses for T 1  in this embodiment are obtained from a transistor blocking oscillator circuit. When low frequencies only are to be amplified a capacitor may be connected in the input circuit.

Title: Improvements in and relating to control arrangements for electrically-driven spinning machinery
IPC: D01H1/30
Filed: 1958-03-21
Abstract: 883,422. Spinning frames. SUGEHOMME, G. E. M. March 21, 1958 [March 25, 1957], No. 9137/58. Class 120(2) [Also in Group XXXVII] A spinning frame for building thread packages consisting of successive conical layers comprises a main motor 100 which drives a supply roller, and a building-motion device for reciprocating a thread-guide rail, as well as a number of parallel spindles mounted on a rail which is progressively lowered during the course of the winding operation. An auxiliary motor 21 drives a crown wheel forming part of differential gearing having one planet wheel keyed to a shaft which is driven by the main motor, and another planet wheel which is freely mounted on the shaft and is coupled to the thread-guides. The motor 21 is supplied from a Ward-Leonard generator 120 which is driven by the main motor 100. A tachometer generator 121 detects the speed of the main motor and applies voltage to a potentiometer 38 which is adjusted in accordance with the instantaneous position of the building-motion device. The resultant voltage is supplied to a valve rectifier apparatus 22 for exciting the field winding 128 of the generator 120. A tachometer generator 122 provides a voltage, proportional to the speed of the auxiliary motor, which is opposed to the voltage obtained from the potentiometer 38. The difference between the two voltages is used for grid-control of the apparatus 22. A voltmeter 125 indicates the speed of the main motor. A reversing switch for the motor 21 may be coupled to mechanism for changing the direction of twist of the thread so that the winding-on direction may be changed with the twisting direction. Another embodiment relates to a machine for converting fibre ribbons into roving, in which the main motor drives a number of drawing rollers and flyers, and the auxiliary motor drives the tubes upon which the ribbons are wound. The field winding of the Ward-Leonard generator is controlled by a tachometer generator, driven by the main motor, and by means of a photo-electric cell responsive to the diameter of the thread packages. Speed control of the auxiliary motor is kept accurate by means of a tachometer generator which is driven by that motor, Fig. 3 (not shown). Specifications 724,122 and 803,590 are referred to.
