Title: Improvements in or relating to magnetic stores
Inventor: WEBLEY REGINALD SIDNEY
IPC: G11C5/02
Filed: 1957-12-11
Abstract: 907,090. Circuits employing bi-stable magnetic elements. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 11, 1958 [Dec. 11, 1957; Dec. 13, 1957], Nos. 38463/57 and 38727/57. Class 40 (9). A magnetic store core controlled by coincident signals in separate conductors is comprised by two similar magnetic elements spaced apart by an insulating layer, a separate insulated signal conductor being associated with each of the elements. As shown in Figs. 1 and 4 which portray an array of storage cores, each core is constituted by a pair of elements 1, 5 formed by applying an 80% nickel-20% iron alloy coating on to the facing surfaces of glass, ceramic or plastic supports 2, 4, the elements being insulated from each other by an insulating layer 6. The elements on each support may be deposited by an evaporation process using a suitable mask to define the individual elements. Alternatively selected regions of an overall deposit may be removed by etching. Each element may be of either rectangular or circular outline as shown, or may be of the form shown in Fig. 3. Rows of insulated conductors X1, X2 . . ., Y1, Y2 ... are associated with the magnetic elements of each support, these conductors being formed on either side of a support by direct printing, overall spraying and etching, or evaporating through a mask, the dimensions being subsequently built up by electroplating. A read-out conductor common to all the elements on one of the supports is also provided. The arrangement is assembled to form a storage matrix by positioning the supports with their respective X and Y conductors at right angles so as to form column and row windings, the supports being brought together with an insulating layer 6 sandwiched between. The dimensions of the supports may be such that those edges project which carry conductor terminals 3. In an alternative construction the insulating layer is constituted by an insulating adhesive such as "Araldite" (Registered Trade Mark) or magnesium fluoride which hermetically bonds the two supports together. The conductors may be arranged in zig-zag fashion as shown in Figs. 1 and 3 so that the row and column conductors are parallel at each storage core position, thus providing a maximum magnetizing force. In a modification the elements and conductors may be formed on each side of a single insulating support.

Title: Honeycomb materials
IPC: B31D3/02
Filed: 1972-08-23
Abstract: 1397811 Seaming non-metallic sheet material DUFAYLITE DEVELOPMENTS Ltd 21 Aug 1973 [23 Aug 1972] 39317/72 Heading B5K Apparatus for adhering together slices 16, 16<SP>1</SP> of structural honeycomb material in the unexpanded state to form continuous expandable material ,comprises a magazine 5, 10, 13, 14, 15 for holding a supply of the slices and delivering them singly to a ramming station, a guideway 19, 23 for receiving the slices from the ramming station and holding the received slices positively located, a ram 21 for ramming the slices into an through the guideway in turn by moving them in their expansion direction against the reaction of slices previously rammed into the guideway, and an adhesive applicator 25 for applying to the slices adhesive positioned to adhere the slices together as they are rammed through the guideway. As shown, layers 4 of slices of honeycomb material are positioned on a lift platform 1 of a fork-lift stillage 2 with their expansion direction perpendicular to the plane of Fig. 1. When a platform 5 is empty, the uppermost layer 4<SP>1</SP> is slid thereon by a set of shoes 6 mounted on a head 7 movable along a track 8 by a pneumatic ram 9. The stillage 2 is raised hydraulically at any time after the shoes 6 have returned to their Fig. 1 position. An upper clamp 10 formed of bars 11 linked by rods 12 is lowered to grip the slices against the platform 5. A pneumatic ram 13 drives a bar 14 to feed the slices individually to the rear 5<SP>1</SP> of the platform 5 whilst downward pressure is maintained by rams 15. The rearward slice 16 is pressed into contact with a check bar 17 and extends over a shutter 18 comprising rods. The bar 17 and the shutter 18 are retracted by rams 26, 27 and the slice 16 falls on to a bed 19 formed by rails 20. The slice 16 is rammed under a clamp 23, similar to the clamp 10, by a ram 21 driven by an actuator 22, downward pessure being applied by rams 24. The ram 21 engages the slice 16 via a glueing head 25 which applies patches of liquid adhesive, e.g. an aqueous dextrin adhesive, spaced apart along the slice. The bar 17 and the shutter 18 are then driven into a position to receive the next slice. When the bar 17 is retracted, a clamp 28 is forced down by an actuator 29 to prevent the slices being advanced over the edge of the platform 5. After the platform 5 has been cleared of slices, a further layer is fed from the stillage 2. The continuous unexpanded honeycomb obtained at the end 30 of the clamp 23 may be taken direct to a manufacturing point, e.g. for producing doors or panels, by a feedway 31 or to a lapping apparatus described in Specification 1,397,812.

Title: Low light level image pick-up tube arrangement
IPC: H04N5/238
Filed: 1975-09-29
Abstract: 1507998 Image intensifier and pick-up tubes THOMSON-CSF 29 Sept 1975 [1 Oct 1974] 39849/75 Heading H1D [Also in Division G3] A television pick-up tube for low light levels (e.g. in a "night-sight" and for visible and near infra-red inputs is combined with an image intensifier, the supply to and hence the gain of the intensifier being controlled in response to the signal from the photo-cathode. A separate circuit reduces the gain substantially to zero at high incident levels (e.g. gun-flashes) or in response to a command signal. The intensifier may have a single stage (Fig. 1, not shown) or two stages 4, 14 each with its own supply voltage. U1, U2 respectively. The luminescent screen 23 of the first stage is coupled to the photocathode of the second by fibre optics 24. The screen of the second stage comprises the dielectric target 6 of the television tube 5. The supply U2 is provided by circuit 15, in which the voltage is regulated by the conduction of transistor 38; this is regulated by the difference between the signal SV from the target 6 integrated at 40a over a number of vertical scans and a reference SM at 41a. U2 is switched at vertical scan frequency by a signal SL and transistor 36. Voltage U1 is generated by circuit 7; it comprises a steady D.C. voltage of amplitude dependent on a signal S2 (by the conduction of transistor 41 and hence the charge on capacitor 40) and a duration dependent on signals S3 (which start U1) and S4 (which stops it). The signals S2 ... S4 are generated in a logic circuit with a digital counter (Fig. 6, not shown). The arrangement is such that, if the integrated value of SV from the target is within a prescribed band centred on the optimum value the duration is constant (determined by the counter) while the amplitude is varied (for any error) by adjustment of the duration of S2 and hence the charging time of 40. U1 is blanked when the current of supply U2 is excessive, showing high input light level. In an alternative arrangement an analogue voltage control system is used in which, within the prescribed error band the amplitude is kept constant and the duration is varied while outside this band the duration is constant but the amplitude is varied.
