Title: Method and Apparatus for Making Steel
IPC: C21C5/46
Filed: 1967-07-27
Abstract: 1,198,112. Oxygen steelmaking. NIPPON KOKAN K.K. July 27, 1967 [July 27, 1966], No. 34691/67. Heading C7D. [Also in Division F4] The throat area of a water-cooled lance for use in steel making is made variable by means of the tapered head 14 of a spindle 13 which is axially movable in the oxygen passage. Vibration of the spindle is prevented by a spindle holder 15. The taper may be in either direction, Figs. 4, 5 (not shown), allowing a ring shaped fire spot in the case of a divergent taper. The head is fixed by a screw head to the spindle 13. If oxygen is supplied to the lance at a constant supersonic flow-rate, the oxygen pressure may be varied merely by varying the cross-sectional area of nozzle. Conversely the oxygen pressure may be maintained constant by varying the nozzle area as the supersonic flow-rate is altered. These methods of control are used in the steel making process described first to supply oxygen at a constant rate and thereafter towards the end of the process to increase the oxygen supply pressure without a corresponding increase in flow-rate. This results in a reduction in the residual impurity content of carbon, nitrogen, and in an avoidance of superoxidation.

Title: Improvements in or relating to signal amplitude coders
Inventor: BARBER DONALD ROBERT
IPC: H03M1/14
Filed: 1962-09-14
Abstract: 1,007,951. Selective signalling. STANDARD TELEPHONES & CABLES Ltd. Sept. 14, 1962, No. 35183/62. Heading G4H. An amplitude sample of a signal wave is quantized into one of n levels in two (or more) stages. Firstly the sample is quantized into one of p (a submultiple of n) levels; the quantized output is subtracted from the sample and the difference so obtained is then quantized into one of q levels (where pq=n). The two quantized outputs are then coded as required. More than two stages may be used provided the product of the number of levels in all stages is equal to n. As shown, the sample S, for example of.level 34, where n= 100, is first quantized into one of ten levels, the quantized output 3 being fed to a signal generator to bring it to the level S 1  at which the sample S was quantized. The difference value (S - S 1 ), in the quoted example, 4, is derived in the subtract circuit and is then quantized into one of ten levels in a second quantizer, the outputs 3, 4 of the two quantizers being then coded as required. In a modification, Fig. 2 (not shown) one quantizer only is used for all the stages, gates ensuring that the sample and the appropriate difference signals are fed sequentially to the quantizer.

Title: Electric muscle stimulator
IPC: H01R13/66
Filed: 1961-09-29
Abstract: 921,992. Electro-medical apparatus. RELAXACIZOR Inc. Sept. 29, 1961 [Jan. 6, 1961], No. 35407/61. Class 81 (2). An electronic muscle stimulator comprises a pulse generator 12 connected in series with an electronic timing oscillator 10 and a source 11 of bias voltage which renders the pulse generator inoperative except when periodically overcome by the timing oscillator. The oscillator is a multivibrator comprising transistors 23, 23a having their emitter electrodes connected together and through a resistor to a power lead 20, the collector elements being returned through resistances 25, 26 to a power lead 21. The pulse width and frequency of the oscillator is adjusted by a potentiometer 27 which is connected between the emitter electrodes and has a centre tap 28 connected to the base elements of the transistors 23, 24. The multivibrator output is connected through a battery 11 and a feedback winding 36d of a step-up transformer 36 to the base of a transistor 35 having a collector electrode connected through a the primary winding 36a of the transformer with the power lead 20. The transistor 35 provides a blocking oscillator which is operative only when the negative parts of the oscillations from the multivibrator overcome the bias provided by the battery 11 and which thus produces a pulsed oscillation across the primary winding 36a. A high initial loading of the blocking oscillator is provided by a capacitor 41 in series with a transistor diode 42 which are shunted across the primary winding 36a so that the amplitude of the pulses increases gradually at the start of the operative period of the oscillator. The primary winding 36a is shunted by a resistor 40 to damp the oscillations and prevent the application of a damaging reverse potential to the collector of the transistor 35. The output from a secondary winding 36c of the transformer is applied across a load potentiometer 44 to an output receptacle 45. Plugs 58, 59 (Fig. 2) connected with an applicator pad (not shown) are connected by wires 55, 56 and a voltage divider network 53, 54 with pins 51, 52 which are plugged into the output receptacle 45.

IPC: H03J1/14
Filed: 1966-08-10
Abstract: 1,185,154. Turret tuners. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd. 17 July, 1967 [10 Aug., 1966], No. 35790/66. Heading H3Q. In a turret tuner with a fine-tuning control coupled to the appropriate tuning member in each position of the turret, resilient means are provided which allow restricted relative rotation between the knob and the turret and disconnect the fine-tuning control from the tuning member while the turret is being rotated. In Fig. 1 the fine-tuning member 5 is adjusted by rotating a sleeve 14 around the turret control spindle 13, motion being transmitted via meshing gears 12, 25 and dog-clutch 8. The spindle 13 is enlarged at its inner end to contain a bore 19 into which the turret shaft 2 penetrates. A compression spring 22 engages a collar 21 on the shaft 2 and a transverse pin 17 on the enlarged portion 23 of the spindle 13, thus urging the latter towards a fixed member 11. By virture of a further transverse pin 15 the sleeve 14 is secured axially with respect to the spindle 13 and is therefore also urged to the right to keep the clutch 8 engaged. Coupling between 2 and 13 is effected by a pin 20 engaging a cam profile 18 attached to the spindle 13. When the latter is rotated, at first the resistance of the usual detent 2a causes the pin 20 to ride up the cam profile, forcing the spindle 13 to the left against the spring 22. The sleeve 14 is also carried to the left and the clutch 8 is disengaged by sideways pull of a flange 26 against the pinion 12. When the pin 20 reaches the end of the profile 18, the spindle 13 starts to turn the turret shaft 2. On reaching the desired detent position of the latter the knob (not shown) on the spindle 13 is released, the spring 22 drives the spindle 13 and sleeve 14 to the right, and a ring 27 on the latter pushes the pinion 12 to the right to re-engage the clutch 8. In a modification (Fig. 2, not shown) the part 23 is replaced by an extended collar (30) which is keyed to rotate with the spindle 13 but can slide axially under the influence of the spring. The collar carries a radially extending arm (43) which moves the rod 10 sideways to engage and disengage the clutch 8, simultaneously meshing and demeshing the gears 12, 25.
