Title: Data storage apparatus
IPC: G11B20/16
Filed: 1969-05-12
Abstract: 1,218,713. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 12 May, 1969 [6 June, 1968], No. 23952/69. Heading G4C. In data storage apparatus, the frequency of a clock oscillator circuit controlling recording of digital data on a rotary data storage device (e.g. a magnetic disc pack) is controlled in accordance with the result of a comparison of the relative timings of clock pulses from the oscillator and timing pulses from a rotary timing signal generator (e.g. a toothed magnetic wheel) connected for rotation with the storage device. The clock pulses, after frequency division in a counter to give them the nominal frequency of the timing pulses obtained by shaping the output of a magnetic sensor sensing the teeth, are each compared with the respective timing pulses and according to which occurs first and the time between them, a duration-significant pulse is produced on one of two leads to charge or discharge a capacitor a corresponding amount. The capacitor voltage controls the oscillator frequency via D.C. and buffer amplifiers. A counter may be driven by the clock and timing pulses, and controlled by an index pulse obtained by sensing a ferromagnetic pin in the wheel.

Title: Method of and apparatus for porcelain enameling sheet metal
IPC: C23D5/02
Filed: 1948-09-13
Abstract: 640,855. Enamelling. CALTON, R. G. Sept. 13, 1948, No. 24025. [Class 56] In a method for continuously porcelain enamelling coil stock of thin sheet metal the sheet is continuously fed longitudinally through a succession of treating chambers, a predetermined amount of slack being maintained in the sheet as it passes through the chambers, and frit paste is continuously applied to the sheet in the first chamber and fired in the second. As shown the coil 10 of sheet metal on spindle .11 passes by means of idle rollers 12 and 14 through a vat 13 of NiSO 4  solution and through a drying chamber 15, and then passes between driven rollers 17 to a spray chamber 18, where vitreous enamel is applied to one or both sides, and a firing chamber 20 heated by resistors 21. From the furnace the sheet passes through driven rollers 22 to a second spray chamber 23 and firing chamber 24 and emerges from the driven rollers 25 as the finished product. The rollers 17, 22, 25 are driven through suitable gearing by a variable speed motor and each roller may be fitted with a clutch. The rollers are situated above the openings of the spraying and firing chambers to permit the formation of slack in the sheet as it passes through the chambers, and this slack in the form of catenaries 36, 37 tensions the sheet sufficiently to prevent buckling &c. The NiSO 4  solution contains preferably 5 to 8 ozs. of nickel sulphate per gallon, and is maintained at 160‹ F. A thicker coating of frit may be applied to the bottom of the sheet than to the top, so that the finished sheet has a concave convex section.

Title: Device for measuring the mass flow rate of a gas
IPC: G01F1/86
Filed: 1971-04-19
Abstract: 1345016 Measuring mass flow COMPAGNIE DES COMPTEURS 19 April 1971 [6 Feb 1970] 24201/71 Heading G4H In a device for measuring the mass flow rate of a gas, the gas is supplied from a reservoir 10 via valve 12 through an intermediate chamber 11. The density and pressure of the gas are measured by sensors 18 and 19. When a measurement is to be made valve 12 is opened and the pressure in chamber 11 is allowed to rise until it is sufficient to produce sonic flow through the sonic neck 15. Valve 14 is then opened. The mass flow rate can then be derived from the pressure and density of the gas in chamber 11, being proportional to the square root of the product of density and pressure. The count output from the pitot tube sensors 18 and 19 passes to current to frequency converters 20 and 21 via gates 22. The pulse signal from converters 20 and 21 is then processed in arithmetic unit 25 to produce an output proportional to the square root of the product of the two input signals. This signal is then counted by counter 26 to give an indication of the total mass. In Fig. 2 (not shown) the density in the intermediate chamber is held constant by means of a feedback loop from the sensor to a throttle valve in the input to the chamber 11. In this case the mass flow rate is proportional to the square root of the pressure. In Fig. 3 (not shown) a number of sonic necks of different sizes may be employed to permit mass flow rates over a wide range to be measured.

Abstract: 239,069. Fairbrother, H., (Jackson Research Corporation). Oct. 13, 1924. Coking processes.-Cannel coal &c. is distilled by external heating in a retort, in which the air and moisture are first driven off by heating and then replaced by an inert gas before raising the temperature, and the heating is regulated or equalized by circulating an inert gas. which may be part of the gas produced in the process, through the charge. A portion of the liquid condensates derived from the retort gases or vapours may be returned to the retort with the inert gas. The charge is heated in a retort 1 by a furnace 7 and the distillates passed through condensers 12, 15 for collecting heavy and light oils and through a condenser 18 leading to a collecting tank 20 from which a fan 23 which acts as a further condenser drives the gas by pipes 27, 28 to an inlet 29 at the top of the retort. Surplus gas passes by pipe 30 and gasometer 31, which acts as a pressure equalizer, to scrubber 34 and outlet 43 to a gas storage tank. At starting, gas from the gasometer 31 is passed through the retort and the air and steam driven out through pipe 8 and replaced with inert gas. The inert gas may be introduced at the bottom and the condensers in the circuit may be dispensed with. Oil condensed from the gas may be introduced into the retort by the gas current.

Filed: 1961-07-05
Abstract: 980,380. Fuzes for self-propelled missiles. U.M.A.L. S.A. July 5, 1961 [June 2, 1961], No. 24234/61. Heading F3A. A hollow-charge rocket projectile has an impact operated fuze comprising a piezoelectric generator 1, Fig. 6, coupled to a selfarming primer system situated behind a warhead 2, wherein a convex pressure block 19, Fig. 3, and an elastic sealing ring 18 enable a movable impact head 20 to transmit the force of impact substantially towards the centre of the generator irrespective of the angle of incidence of the projectile with the target. The generator comprises a piezo-electric crystal 11 supported rearwardly by a plate 9, connected to a conductor 16, and frontally by a metallic casing 12. The output end of the conductor 16 is connected to a metal contact 41 which forms part of an assemblage of contacts 39, 40 and insulators 30-33, Fig. 11, and Fig. 15 (not shown), fixed to a hollow cylindrical block 24 housing a rotor 47. The rotor is maintained in the unarmed position against the action of a spring 53 by a bolt 61 which protrudes into a blind bore 59, Fig. 9. Within a diametral bore 68 of the rotor is housed a primer 72 (not shown), in electrical contact with a pin 69, Fig. 11. Prior to launching, a safety pin 77, Fig. 9, is removed, thereby freeing a passage 78, and on launching the rotor sets back sufficiently against the action of spring 53 to release its frictional grip on the bolt 61 which itself sets back and passes through passage 78. The rotor is then rotated anti-clockwise by spring 53 until pin 69 is stopped by contact 40. The fuze is now armed since an electrical pulse from the piezo-electric generator can be fed to the primer via contact 40 and pin 69, and in the armed position the longitudinal axis of the diametral bore 68 is coincident with axis Y-Y, Fig. 9, and has its open end 74 adjacent a cylindrical neck 25 which protrudes into the warhead 2. Reference has been directed by the Comptroller to Specification 740,195.

Abstract: 500,744. Dispensing liquids and fluent solids. LOWE, A. M. Sept. 9, 1937, No. 24569. [Class 116] An apparatus for use particularly in garages and service stations for dispensing measured quantities of different grades of oil, but applicable also to the dispensing of liquids and fluent solids generally, comprises a cabinet subdivided into a series of compartments, each adapted to contain a measuring vessel or pouring can and provided with a door adapted to interlock with means for controlling the supply of oil &c. to the measuring vessel, whereby' the supply is cut off when the door is open or partially open and can only be established when the door is closed. In the form illustrated, the cabinet 3 is divided into a series of vertically disposed compartments of different sizes to receive standard measures 8, 9, 10, which latter are supplied with oil through taps 15. The oil is fed into the supply pipe 17 by gravity or from a storage tank 19 by means of a pump 18. Each tap 15 is furnished with a spindle 14 which may be engaged by an operating key 21 inserted through an aperture in the front wall of the compartment when the door 11 of the latter is closed. When the door is partly raised, it obstructs the aperture in the front of the compartment and so prevents insertion of the key 21. Alternatively, a key-hole shutter may be mechanically connected to the door in such a way that it is closed when the door is opened. The sizes of the compartments may be so arranged that the insertion of a measuring vessel of a size larger than that for which a compartment is intended, cannot be effected. A series of recording meters or counters 20 are mounted on the lower portion of the cabinet, each being connected mechanically or electrically to the door of one of the compartments in such a manner that each opening movement of the door, prior to the removal of the measuring vessel, is recorded. Alternatively, the indicating means for each compartment may comprise a number of balls or counters, the lower one being ejected into a collecting receptacle each time the door of the compartment is raised. When the indicators are controlled electrically, the pumps 18 may also be so controlled, in order that operation may cease in the event of failure of the supply current. The oil tanks 19 may be replenished from standard oil drums 22 stored in compartments at the back of the cabinet provided with hinged lids 23 and slidable rear panels 24. An electric or other heater may be provided to maintain the oil at a temperature which will enable it to flow readily from the measuring vessels.
