Title: Liquid-fuel injection device
IPC: F23D11/34
Filed: 1972-01-07
Abstract: 1367204 Tuyeres; fuel atomizers INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE 7 Jan 1972 [20 Jan 1971] 741/72 Headings F5B and F4T Liquid fuel is fed into a tuyere 2, for example for heating a blast furnace, through a central movable body 6 and/or at the level of a sonic throat 4 of tuyere 2 and in order to maintain effective fuel atomization a supersonic shock wave is maintained in the outlet nozzle 5 by moving the body 6 in response to a detected difference between the pressure at the tuyere inlet of a comburant gas, supplied via conduit 1, and a reference pressure which, it is known, will, if applied to said inlet, maintain said shockwave for all values of comburant flow-rate within predetermined limits. In situations wherein the pressure downstream of tuyere 2 remains substantially constant, a regulated reference pressure is applied to one side of a diaphragm 11 the other side of which is subjected to the tuyere inlet-pressure. Diaphragm 11 thus moves body 6 in response to inlet pressure changes. In situations wherein the downstream pressure varies with comburant flowrate, the reference pressure applied to diaphragm 11 is the sum of the pressure adjacent the outlet of nozzle 5, applied via conduit 14, and a predetermined differential pressure applied by a spring 15 and adjusted by a control 16. In alternative embodiments, a coupling rod 7 may be replaced by electromechanical or pneumatic means; e.g. the difference between the two pressures may give rise to an electrical signal activating a servo-mechanism. The rod 7 and body 6 may be cooled by a circulating cooling fluid or by contact with one end of a thermal conductor cooled at its other end by vapourization of a liquid.

Title: Process for making tampons and the product produced
IPC: A61F13/22
Filed: 1940-01-15
Abstract: 538,164. Catamenial tampons. BAILEY, S. P. Jan. 15, 1940, No. 906. Convention date, Jan. 14, 1939. [Class 81 (ii)] A vaginal tampon comprises a layer of absorbent fibrous material compressed to a stiff, substantially cylindrical body of small diameter in relation to its length, said body being permanently restrained at one end but free to expand at the other, and a withdrawal cord attached to the restrained end of the body. In one form, the tampon is made from a single layer 1, preferably a disc, of absorbent material such as cotton, having a withdrawal cord 6 sewn to its centre. The layer 1 is moulded into a cup-shaped body, Fig. 4, which is then subjected to lateral compression to form a substantially cylindrical tampon 3, Fig. 5, the lower end 4 of which is less compact and thus softer and larger than the remaining portion. The absorbent material may be provided with an outer waterproof layer, or several layers of absorbent material, with a waterproof layer next the outermost layer, may be used. Instead of forming the cup-shaped body from a disc of absorbent material, it may be produced directly by spinning loose absorbent fibres into conical form. The cylindrical shape of the tampon may be temporarily maintained by compressing it under such pressure that the tampon will not expand until it is wetted. Alternatively the tampon 3 may be inserted in a tube 10 which may serve as an applicator, from which the tampon may be ejected into a body cavity by a rod 11, Fig. 10. After ejection, the tampon expands immediately or after being wetted, into hollow conical form as shown in Fig. 11. In a modification, Fig. 18, the tampon is formed by winding a strip of absorbent material upon itself, the lower end of the tampon being constrained from expanding by means of the withdrawing cord 6 or by means of a band or by sizing it.

Title: Improvements in or relating to preparation of catalytic and adsorbent magnesia-containing materials
IPC: B01J21/10
Filed: 1950-01-13
Abstract: Magnesium metal or an alloy thereof is reacted with anhydrous methyl or ethyl alcohol, if desired in the presence of a catalyst such as mercury, mercuric chloride, aluminium chloride or iodine, and the alcoholate so formed treated with a substantially water-insoluble alcohol, if desired in admixture with a petroleum distillate. Suitable water-insoluble alcohols are n-, secondary- and isobutyl alcohols, pentanol-1, -2, and -3, 2-methyl butanol-3 and -4, hexanol-1, -2 and -3, methyl pentanols, di-methyl butanols, and heptyl- and hexyl alcohols.  Suitable petroleum distillates are those boiling in the range 200-500 DEG  F. Methyl or ethyl alcohol liberated is removed for reuse by distillation from the higher alcoholate formed.ALSO:Magnesia is prepared by reacting magnesium metal or an alloy thereof with anhydrous methyl or ethyl alcohol, if desired in the presence of a catalyst such as mercury, mercuric chloride, aluminium chloride or iodine, treating the alcoholate so formed with a substantially water-insoluble alcohol, if desired in admixture with a petroleum distillate, and hydrolyzing the resultant substituted alcoholate with water, at say 100-200 DEG F. to form a slurry of magnesia, and a separable layer of the water-insoluble alcohol for reuse.  Suitable water-insoluble alcohols are n-, secondary- and isobutyl alcohols, pentanol-1, -2 and -3, 2 methyl butanol-3 and -4, hexanol-1, -2 and 3, methyl pentanols, dimethyl butanols, and heptyl- and hexyl alcohols. Suitable petroleum distillates are those boiling in the range 200 DEG -500 DEG F. Methyl or ethyl alcohol liberated is removed for reuse by distillation from the higher alcoholate formed. Separation of the hydrolized mixture into two layers is effected at 70 DEG -200 DEG F., and the alcohol-hydrocarbon mixture is dried by p  distilling off the water.  Small quantities of said mixture separating from the distillate are returned to the main separator. The magnesia slurry may be dried, or mixed with say, ammonium molybdate or dichromate, dried, and activated at 850 DEG F. to produce catalysts.  Where mercury is used as a catalyst in the first stage, it may be recovered by contacting the magnesium alcoholate solution prior to hydrolysis with copper or silver, which may be deposited on pumice, silica gel, alumina &c. and subsequently distilling at a temperature up to 1000 DEG F.  Hydrogen evolved in the first reaction may be compressed.

Title: Method and apparatus for controlling a stepper motor
Inventor: WHITE JAMES NORMAN JACKSON
IPC: H02P8/00
Filed: 1986-09-25
Abstract: A method and apparatus for controlling a stepper motor and a disk drive is described for minimization of stepper motor oscillations for a single step, minimizing the time taken for the stepper motor to move between tracks for multi-track seeks, and reduction of angular hysteresis due to the mechanical and magnetic properties of the stepper motor construction. This control is achieved using a microprocessor-based circuit adapted to drive the stepper motor in accordance with predetermined programs. Oscillations of the stepper motor are damped by controlling, using one program, the current applied to the stepper motor during the last step of its motion by switching this current on and off within small predetermined time intervals. The time taken to move between tracks is controlled by another program in which the non-linear torque speed characteristics of a particular stepper motor are matched by a non-linear pulse rate which is determined by data held in the memory of the microprocessor circuit. This data can be modified to suit the requirements of the stepper motor and load. Another program controls minimization of hysteresis by ensuring that each track on the disk is approached from the same direction and from the same previously energized set of windings. The microprocessor controls the direction of motion of the stepper motor and hence decides whether or not the read/write head should cross the desired track and return it to ensure uniformity of approach.

Title: Removing method of external noise in read of magnetic medium
Inventor: MIYATA KUNIO
IPC: G11B5/09
Filed: 1983-01-08
Abstract: PURPOSE:To eliminate the influence of an external periodic noise by providing specially a read head which detects only the external noise. CONSTITUTION:The read head 12 which slides along an arm together with a reading/writing head 11 which contacts a magnetic medium 13 is arranged near the head 11. An induced voltage from the medium 13 is extremely small, so the head 12 picks up the noise substantially. The heads 11 and 12 have exactly the same structure and characteristics. The head 11 outputs the composite waveform (E+e) of an actually read signal E and the noise (e), and the head 12 outputs the noise (e). Then, AMPs 21 and 22 have the same characteristics and a degree G of amplification. The variable resistance VR of a signal adding circuit 24 is substantially R and provided to correct characteristic variance, etc., of the heads and amplifiers. Its output is G(E+e)-Ge=GE, removing the external noise.

Title: Transmission method for voltage state of battery
Inventor: YABE YASUSHI
IPC: G06F1/28
Filed: 1990-01-05
Abstract: PURPOSE:To eliminate the need of another separate signal line, and also, to simplify the program of a CPU by converting a result of detection to other key code than a key code for showing a key input, and transmitting it to the CPU by a transmission means, when a voltage of a battery becomes a prescribed value or below. CONSTITUTION:A transmission means 3 converts a key input from a keyboard 2 to a key code for showing its key input and transmits it to a CPU 4, and on the other hand, whether a voltage of a battery 1 is a prescribed value or below or not is detected and a result of its detection is converted to other key code than a key code for showing the key input and transmitted to the CPU 4. When the key code sent from the transmission means 3 is other key code than the key code for showing the key input from the keyboard 2, the CPU 4 judges that the voltage of the battery 1 drops to the prescribed value or below and executes a necessary processing. In such a way, a separate signal line is not required, and also, the program of the CPU 4 is simplified.
