Title: Improvements in rheostats for use in electric calculating apparatus
IPC: G06G7/163
Filed: 1931-10-15
Abstract: 392,207. Electric switches. BAULE, M. E. A., 13, Rue Leon Gambetta, Chaville, Seine-et-Oise, France. Oct. 15, 1931, No. 28642. Convention date, Nov. 28, 1930. [Class 38 (v).] A rheostat for calculating the value y=f(x) comprises resistances connected in series by contacts spirally arranged on a rotatable cylinder and co-operating with a brush which can be traversed parallel to the cylinder, the total number of contacts passed over by the brush being visually indicated and the value of each resistance being equal to dy/dx. The brush 57, Fig. 2, is moved by a screw 59 geared to the rotatable cylinder 54 carrying the contacts 56. The position of the contact engaging the brush at any time is shown on a counter 61. The Specification as open to inspection under Sect. 91 describes resistances comprising loops which may be adjusted by sliding along them a slider to short-circuit any desired amount of the loop. This principle is applied in the rheostat for effecting multiplication shown in Fig. 6 (Cancelled) and consisting of wire wound on two bars 46, 47, a series of sliders 49 being connected to a bar 50 the position of which is indicated on a scale 53. A slider 52 moves on a bar 51 and when this slider is set to a position x1 and the bar 50 to x2 the total effective resistance is x1 X x2. This subject-matter does not appear in the Specification as accepted.

Title: Magnetic Thin Film Storage Element
IPC: G11C5/02
Filed: 1968-06-17
Abstract: 1,168,046. Magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 17 June, 1968 [14 July, 1967], No. 28708/68. Heading H3B. [Also in Division H1] A thin magnetic film storage element including a pair of magnetic films 20, 24 disposed on one side of an electrically conducting substrate 12 has one drive line 16 disposed between the films and the substrate and a second drive line 22 disposed parallel to drive line 16 and between the films, the drive lines 16 being spaced so that the magnetic field intensity in each of the films 20, 24 is substantially equal when the appropriate current is passing through these lines in the same direction. A word line 28 is arranged transverse the films 20, 24, and in operation of the store shown in Fig. 1 a positive pulse is passed through word line 28 to provide a hard axis field and a positive or negative pulse is passed through the first and second drive lines 16, 22 in parallel by means of switches 30, 36 in order to write a " 1 " or " 0 " into the element. Read out is achieved by connecting read amplifier 40 to drive line 22 and passing a word current through word line 28. The two magnetic films 20, 24 may be closed at their edges by two magnetic strips Fig. 5 (not shown). When current passes through the drive lines 16, 22 the two fields 60, 62 set up by the current, Fig. 6, are such that there is zero magnetic field in film 20 whereas the field 64 due to the combined currents in the drive lines 16, 22 magnetizes film 24 in the direction shown. An image current is also produced in the ground plane 12 as shown by virtual drive lines 16<SP>1</SP>, 22<SP>1</SP> and the effect thereof is to produce resultant magnetic fields 72, 74 which pass through the magnetic films 20, 24 respectively. The resultant effect is for film 20 to be magnetized from right to left and film 24 from left to right since magnetic field 64 is greater than field 74. The magnetic field intensities in the two films may be made equal by adjusting the amount of current through the lines 16, 22 or by adjusting the distance between the ground plane and drive lines 16, 22. An array of the elements of Fig. 1 may be formed on a common substrate, Fig. 8 (not shown), by depositing elongated conductor and magnetic film strips thereon. Read out may be nondestructive or destructive. The arrangement described minimizes the effect of full bit fields and stray fields on unselected elements.

Title: Improvements in magnetic cores and methods of producing them
IPC: H01F1/24
Filed: 1936-10-30
Abstract: In the manufacture of magnetic cores for loading coils &c. from finely divided magnetic material, colloidal andalusite is employed in the insulating material with a binder, e.g. sodium silicate. The mixture also includes a substance such as ammonium chromate which liberates oxygen on heating.  The heating operation takes place after the cores have been pressed, and the oxygen serves to produce an oxide coating on any metallic portions which have been left uncoated or have become exposed.  In an example, powdered iron is mixed dry with ,5 per cent by weight of colloidal andalusite, and about 2,6 per cent of an aqueous solution of sodium silicate is added, the mixture being tumbled to dryness and heated to about 150 DEG  C.  An aqueous solution of ammonium chromate, aluminium chlorate or sodium chlorate representing about ,3 per cent by weight of the powder is added and the mixture again dried and heated.  The material is then pressed into rings at a pressure of about 300 tons per sq. inch, and heated for about an hour to a temperature sufficient to liberate oxygen, e.g. about 425 DEG  C.
