Title: Magnetic thin film device
IPC: G11C7/02
Filed: 1966-09-06
Abstract: 1,142,035. Magnetic storage apparatus. HUGHES AIRCRAFT CO. 6 Sept., 1966 [6 Oct., 1965], No. 39745/66. Heading H3B. [Also in Division H1] A uniaxial or isotropic magnetic thin film storage element has magnetically coupled thereto a plurality of electrical conductors spaced apart in side-by-side arrangement and connected in series, the inner ones passing over the element and the outer ones being outside the bounds of the element. The conductors are arranged so that the current through the inner conductors is in the same direction and produces a cumulative magnetic field whereas the current through the outer conductors is in the opposite direction to the first direction so that the associated magnetic fields reduce the magnetic field strength in the fringe areas of the cumulative magnetic field. In the arrangement of Figs. 3, 4, a plurality of thin film elements 12 are deposited on a glass substrate 54 which is sandwiched between two congruent sets of conductors 16 to 22 and 28 to 36 produced by printed circuit techniques. A current is applied to terminal 40 on conductor 14 and flows in the direction shown by the solid arrows in the upper conductors until it reaches the end of conductor 24 when it is transferred by circuit connection 25 to the lower conductor 26 and travels in the directions shown by the dotted arrows in this conductor to output terminal 42. Thus the current in the conductors situated over the film element 12 produce a cumulative magnetic field whereas the current flowing through the conductors 18, 22, 30 and 34 not situated over the element 12 produce a field opposite to the cumulative field and tend to cancel out this field in the fringe area and hence isolate the element, Fig. 5 (not shown). When a plurality of units are employed to form a memory conductors 14, 26 extend parallel to the axis of anisotropy and function as a word winding. A common bit/sense line is positioned perpendicular to the word line. Instead of single elements, sheets of thin films may be employed with the windings defining discrete areas of the sheets. Read-out is non-destructive.

Title: Apparatus for use in making bricks
IPC: B28B5/08
Filed: 1975-09-30
Abstract: 1529191 Feeding a turntable brick press F H DROSTHOLM 30 Sept 1975 [30 Sept 1974] 39923/75 Heading B5A Bricks are made from soil or sand/lime in apparatus comprising a turntable 62 (Fig. 2) supporting a plurality of brick moulds 67 (shown as multi-cavity) each open at opposed ends, the moulds being moved successively through mould filling (A), compressing (B) and ejecting (C) stations. The filling station includes an offset feeder 50 and a plurality of measuring devices 72/77 arranged to transfer material into the nearest adjacent mould, and when in registration with a mould each device 72 or 77 defines therewith a common chamber in which the material is precompressed by opposed press elements.  As shown, six moulds 67 pass through two series of fill/compress and eject stations (A)-(C) to produce solid or hollow bricks, the turntable being turned intermittently for location in each station by a plunger 92. The material is granulated, dried, weighed and mixed with additives (e.g. pigment) before transfer to the offset feeder hopper 50 and the measuring devices 72/77, which comprise telescoping portions allowing variation in the charge size (or include a plunger acting as a movable base). The devices 72/77 rotate about an axle 69 to bring them alternately over an adjacent mould, with their partitioned cavities in alignment. Two opposed plungers 77/78 (Fig. 11, A1) engage and precompress the material while transferring it from measuring device 71/72 into the mould 67 (Fig. 11, A2). At the compressing station (Fig. 11, B), plungers 83/84 effect high compression, while ejection by a plunger 89 (Fig. 11, C) occurs at the final station. The pressing plungers comprise fingers, one for each mould part, those for the ejection plunger being of unequal length (Fig. 8). The bricks are humidity cured or autoclaved. In a second embodiment for moulding hollow bricks about cores 134 (Fig. 22) the mould 67a is filled from hopper 71a by lowering of bottom plunger 78a with the cores projecting into the hopper. Thereafter precompression is effected by plunger 127, and high pressing by a plunger surrounding the cores at the compressing station. The mould comprises a split outer frame and interengaging inner mould walls and partitions lined by replaceable or reversible steel liners (see Specification 1,529,192).

Abstract: 1,272,336. Change-speed control. TOYOTA JIDOSHA KOGYO K.K. 5 Jan., 1970 [25 March, 1969], No. 40386/70. Divided out of 1,261,471. Heading F2D. The subject-matter is the same as that of the main Specification 1,261,471, except that the acceleration-responsive control is omitted, the automatic parameters being now solely throttlesetting and output speed. The claims are directed to the feature that, in the absence of electrical control supply, either due to failure, or intentional switch-off, the manual ranging valve gives invariable first, second and third ratios in the settings L, 2 and D respectively, this being due to the arrangement of the hydraulic circuit, and to the fact that the automatic 1-2 and 2-3 solenoid shift-valves are downshifted by energizing their solenoids and are upshifted by springs when their solenoids are de-energized, either by the automatic control circuit or by absence of electrical supply.
