Title: Magnetic information storage element
IPC: G11C19/08
Filed: 1964-10-16
Abstract: 1,077,653. Magnetic storage apparatus. TELEFUNKEN PATENTVERWERKTUNGS G.m.b.H. Oct. 16, 1964 [Jan. 27, 1963], No. 42298/64. Heading H3B. [Also in Division H1] In storage apparatus employing thin magnetic storage layers 5 the storage layers are separated from a system of insulated conductors 2, 3 printed on a soft magnetic base 1, 1<SP>1</SP> of high permeability by a non-magnetic layer 4 at positions of the layers 5 acted on by currents in the conductors 2, 3 but are on the base 1, 1<SP>1</SP> at regions around these positions. In the arrangement of Fig. 1 the base 1 comprises a thin soft magnetic metal foil or metal layer 1<SP>1</SP> stuck on or electrically deposited on a non- magnetic base-plate, or a thick soft magnetic ferrite plate. Instead of the conductors 2, 3 crossing at right angles as shown in Fig. 1 they may pass underneath the layer 5 parallel to each other. A plurality of the units shown in Fig. 1 may be arranged in a coincident current matrix, Fig. 3 (not shown) in which the conductors 2, 3 form part of orthogonal sets of writing and interrogating wires and two reading wires arranged for compensating disturbance voltages are provided. In a word organized store the reading wires are omitted and the ywires serve for the word and interrogation currents and x-wires for the digit currents and reading wires. In the arrangement of Fig. 4 (not shown) the word and digit wires run parallel under the storage layer bridges and may be printed one on top of the other. The magnetic storage layers may be of anisotropic material and are circular in shape, Fig. 5 (not shown) so that a magnetic circuit with the base 1 is enclosed almost on all sides. If the preferred direction of magnetization is set at an angle to the co-ordinate conductors 2, 3 magnetization reversal by rotation may be obtained by current through a single wire. Read out may be non-destructive. By appropriately shaping the magnetic storage layer 5, Fig. 7 (not shown) preferred directions of magnetization can be set up at angles of 45 degrees round the layer, Fig. 8, shows an arrangement which can serve for the storage and counting of pulse trains, the storage layer being in the form of a triangle. Initially the triangular region is magnetized transversely to the direction of current through write line 2. The pulses to be counted are then sent through the same wire, each pulse causing a partial strip-shaped reversal of magnetism in the triangular area progressing from the apex to the opposite side which is detected by read wire 3. In the development of Fig. 8, Fig. 9 (not shown) the active region of the storage layer is divided into strips which can be interrogated individually by means of separate interrogation wires. Fig. 9 may also be used for producing pulses which appear with phase displacement at a series of output terminals.

IPC: G21C17/10
Filed: 1959-12-11
Abstract: 895,759. Detecting neutrons; discharge apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 24, 1960 [Dec. 11, 1959], No. 42307/59. Classes 39(1) and 39(4). A fission chamber for use at high temperatures comprising a tube having a chamber region at one end and a support region extending away from the chamber region, a central electrode insulatedly mounted within the chamber region, a connecting wire extending from the electrode supported d coaxially within the support region, a layer of fissile material adjacent the chamber volume formed between electrode and tube within the chamber region, the construction being such as to permit the flow of gas between the chamber and support regions of the tube, is characterized in that the tube is filled with a gas comprising xenon. The gas may be xenon alone at a pressure of 3.5 atmospheres at room temperature, or may be a mixture of xenon and argon. In Fig. 1 the outer tube 1 is crimped at 2 to form an internal stop for locating an alumina disc 3 having a central hole through which projects one end of a central electrode 4; the other end of electrode 4 is located in a hole in alumina disc 6, and a nickel cylinder 8 coated internally with uranium 235 spaces apart the discs 3 and 6. The region between discs 3 and 6 forms the fission chamber, the remainder of thet tube forming a support extending outside the core of the reactor in which the apparatus is used and enclosing a connecting wire 10 one end of which is welded to electrode 4 and the other end of which is supported by a spring 15 from a lead-in wire. Threaded on the wire 10 are a plurality of alumina tubes 11 which space apart alumina locating discs 12; discs 12 and discs 3 and 6 are provided with slots to facilitate evacuation and filling of the tube through a sealable copper pipe 21. The tube 1, electrode 4 and wire 10 are all made of 80% nickel/ 20% chrome alloy to withstand high temperatures. It is a characteristic of fission chambers that there is a plateau in the curves of count rate against gas pressure; with a xenon filling the plateau is narrower but at a lower gas presure than with argon. A mixture of argon and xenon can be used to provide plateau characteristics intermediate in pressure and length between those of the two gases.

Title: Spectrometric apparatus
IPC: G01J3/28
Filed: 1964-10-23
Abstract: 1,089,679. Spectrometric apparatus. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. Oct. 23, 1964 [Nov. 14, 1963], No.43272/64. Heading G1A. [Also in Division G2] Apparatus for spectrometric analysis of a beam of radiation as from a source S includes an input device G and an output device G<SP>1</SP> positioned before the detector D. The two devices each have alternate zones of different transmissivity, normally clear and opaque, and the image of the zones of the input device are arranged to coincide for one frequency of radiation, with the zones of the output device. As shown radiation passing through one set of zones in plate G is directed by collimating mirror M to reflecting dispersive grating R and back via mirror M to plate G<SP>1</SP>. For the frequency of radiation at which the image of the zones of G coincides with the zones of G<SP>1</SP> all the radiation from G will either pass through or be stopped by G<SP>1</SP> to give a maximum or minimum output from the detector D. For frequencies to either side there will be a rapid change in intensity gradually flattening out to a level at which approximately half the radiation falling on G<SP>1</SP> passes through it. Various zone patterns, the shape of one of which is indicated on the figure, may be used to achieve this result. In order to pick out a narrow band of frequencies, equivalent to that selected by a small slit yet with a higher radiation intensity at the detector, provision is made to cyclicly move the image of the input device relative to the output device. This may be done by movement of either device or both, or by moving the mirror M or grating R. It results in the narrow band of frequencies for which the image of G coincides with G<SP>1</SP> bearing a modulation at the frequency of cyclic movement. The output of the detector is fed through a circuit tuned to select only the signals so modulated. The whole spectrum may be scanned by rotation of the grating R. In a modified apparatus the devices G and G<SP>1</SP> are physically combined, the image of the device, acting as an input device, being formed inverted with respect to the optical axis on the device acting as output device so that at the frequency of zone coincidence all the light fed into the apparatus through the transparent zones is reflected to the detector from reflective surfaces on the rear of the opaque zones.

The slot enables the second portion to be connected to a stud which is connected to the other member, the stud having a shank 20 with an abutment 23 at one end and an abutment 22 and shoulder 21 near the other end, the arrangement being such that the second portion is engaged with the stud so that the stud is disposed in the slot 18 with the enalarged end portion of the slot, which is circular, engaged by the shoulder 21, the arms of the second portion being trapped between the two abutments 22, 23. In the construction shown the axis of the slot 18 is disposed parallel to the axis of the rod or tube when it is engaged by the arms of the first portion but in a modification the axis of the slot 18 is at right angles to the axis of the rod or tube.
