IPC: G11C11/56
Filed: 1956-07-13
Abstract: 813,726. Electric digital-data-storage apparatus. STANDARD TELEPHONES & CABLES Ltd. July 13, 1956, No. 21801/56. Class 106 (1). [Also in Group XXXIX] A plurality of bits of information are stored in a single magnetic toroid by applying successive electric pulses of such polarity and strength as to leave concentric annular magnetic fields, each in a magnetic state denoting the value of a corresponding bit. A series of pairs of pulses, P1, P2, &c., of opposite polarity and decreasing amplitude, Fig. 2 (a), are applied to a recording coil passing through the toroid, together with superposed pulses representing the input information to be stored, Fig. 2 (b), the information pulses being so timed as to coincide with the second pulses P2 of each pair P1, P2, a " 1 " being stored by increasing the amplitude and a 0" by leaving the amplitude unchanged. Thus the toroid becomes differentially magnetized as shown in Fig. 3 (a), a stored " 0 " being represented by positive flux (clockwise arrow) and a stored " 1 " by negative flux (anticlockwise arrow) with a screening buffer of positive flux. The stored information is read out by applying a series of pulses, Fig. 2 (c), of increasing amplitude to a reading coil, the information in the resulting output, Fig. 2 (d), appearing in a read-out coil in reverse order as compared with the input. A storage array may be formed of a plurality of ferrite blocks, each block containing a plurality of holes drilled through it, the blocks being arranged with their holes aligned to receive " column " wires, and each block having a " row " wire threading all its holes, the row wires being sequentially and cyclically pulsed by an access selector (Fig. 1, not shown).

Title: A process for the manufacture of a non-hygroscopic or slightly hygroscopic double salt from calcium nitrate
IPC: C01F11/42
Filed: 1927-08-18
Abstract: 276,350. Azogeno Soc. Anon. per la Fabbricazione Dell'ammoniaca Sintetica e Prodotti Derivati Toniolo, C., and Tanzi, B. Aug. 19, 1926, [Convention date]. Manures.-A double salt which is non-hygroscopic or is less hygroscopic than calcium nitrate is prepared by mixing ammonium sulphate and anhydrous calcium nitrate in the presence of two molecules of water for one of nitrate. Twice this quantity of water may be present, but in this case the excess is finally expelled by heat. The water may be added to either salt or to the mixture as moist air, steam or liquid; or hydrated calcium nitrate Ca(NO3)24H2O prepared by cooling a 70 per cent solution of the nitrate may be used. Ammonium sulphate may be added to the dissolved salt. If the nitrate is basic, nitric acid is first added. The salts are preferably mixed in equimolecular proportions; excess nitrate or sulphate may, however, be added, but not less than 30 per cent of ammonium sulphite should be present. The ammonium sulphate may be replaced by mono- or bi-ammonium phosphate, and potassium salts, ammonium nitrate or urea added to obtain mixed fertilizers. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also the use of excess ammonium sulphate, but less than two molecular equivalents to one of calcium nitrate. This subject-matter does not appear in the Specification as accepted.

Filed: 1958-07-10
Abstract: 856,150. Driving mechanism for mixing machines. MIXING EQUIPMENT CO. Inc. July 10, 1958, No. 22156/58. Class 86 [Also in Group XXVI] A driving mechanism for a mixing machine 35 comprises an electric motor 67, Fig. 1, driving, through a shaft 69, coupling 71 and a worm-gear unit, an agitator drive shaft which includes two axially aligned sections 49, 55 connected by a coupling 51, 141 so as to be capable of axial movement in order to effect removal and replacement of a sealing means 75 (Group XXVI). The worm-gear is mounted in a housing 39 and fixed on a quill shaft 57 which is mounted in bearings 59, 61 and connected to the shaft section 49 by a coupling 63. The shaft section 49 is mounted in bearings 45, 47 carried in frame members 41, 37, the upper bearing 45 being located in a threaded housing 113 so that, in order to permit the removal of the seal 75, the shaft may be lifted by the rotation of handles 115 attached to the housing. To effect the seal removal, the clamping nut 133 on the bearing 47 is released and the connected shaft sections lifted as just described, the shaft being retained in the lifted position by lugs 107 in a ring member 99, engaging in a thread-groove 103 in a ring 23 attached to the closure-plate 25 of the mixing machine container; the engagement of the member 99 with the ring 23 also serves as an auxiliary seal while the main seal is removed thus avoiding the draining of pressurized fluid in the container. The coupling 51, 141 is then released, the shaft lifted further and, upon removal of the half-coupling 141, the seal can be removed. The reverse procedure is adopted for reassembly. Fig. 10 shows an arrangement in which a third shaft-section 201 is connected by couplings 51 and 203, 197 to the sections 49, 185 so that when the shafts are lifted as previously described, the section 201, together with the main seal, can be removed as a complete unit. The sealing arrangements described may be applied to containers in which the shaft passes through the bottom or the side of the mixer casing.

Abstract: 628,930. Dial and indicator toys. DICKINSON, E. N., DICKINSON, D. R., and DICKINSON, J. A. Aug. 9, 1947, No. 22189. [Class 132 (iii)] A toy of the dial and indicator type has a frictional gear for transmission of drive from a spindle to the indicator. In the toy wrist watch shown in Figs. 1 and 2, a paper dial 11 is stuck on to a similarly shaped metal support 12 and is contained in a case comprising two inter-fitting elements 13 and 14 with a transparent front 15 and hands 16. The wristlet may consist of elastic cord engaged in eyelets 13c. A knurled knob 17a turns a shaft 17 on which there is a rubber collar 19 which bears on a toothed wheel 20. Tabs 20b project from the wheel 20 through holes in the support and dial and carry the hands of the watch which are united. The shaft 17 is mounted in aligned holes in the watch casing and is secured against longitudinal displacement by a collar 17b. An alternative mounting is shown in Fig. 4 in which a tab 12a, which has a hole in it, is punched out of the support 12 and serves as a bearing for the shaft. Instead of using a collar 17b the end 17s of the shaft is split so as to secure it against longitudinal displacement, and in this case a plane wheel may be used as the collar 19 is held more securely in contact with the wheel.

In an automatic temperature-control system the energization of a main electric heater is switched from high to low or off by a device responsive to a temperature controlled by the heater and the energization of an auxiliary electric heater for the temperature-responsive device is derived through a transformer, the supply to which is switched in parallel with that to the main heater. In Fig. 2, the temperature of a medium heated by an electric heater element 9 is thermostatically controlled by a contact making mercury thermometer 11 controlling the supply to the heater through contacts 3 of a relay 5. An auxiliary lowvoltage heater 10, supplied through a transformer 12, the energization of which is also controlled by relay contacts 3, is associated with thermometer 11 to reduce the temperature differential. In a modification, the temperature is controlled by relay contacts shortcircuiting a resistor in series with the heater. Use of expansion, bimetallic, thermocouple or temperature-variable resistance type temperature responsive devices is referred to. In the case of an expansion helix the auxiliary heat may be applied by passing current through the helix.
