Title: Magnetic film stores
IPC: G11C7/02
Filed: 1965-03-26
Abstract: 1,046,138. Magnetic structures. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 26, 1965 [April 6, 1964; May 5, 1964], No. 13073/65. Heading H1H. [Also in Division H3] The storage elements 10, Figs. 1, 5 (not shown), of a magnetic film storage matrix consist of two magnetic films 16, 22, which are arranged at right angles to one another (Fig. 1) or parallel with one another (Fig. 5) and are separated by a layer of non-magnetic material 18, 20, Fig. 2, two opposite edges of one film 16 being in contact with the other film 22 to effectively form a closed magnetic loop. The easy axes of the two films are parallel and are perpendicular to the length of the film 16. In one embodiment, Fig. 2, a conductive lamina 12 carries an insulating coating 14, on which is deposited the first film 16, an insulating strip 18, a conductive strip 20, the second film 22 perpendicular to the first film, an insulating strip 24 and a second conductive strip 26. The conductive strip 20 may be omitted if the film 16 is of a low-resistivity material, such as an iron-aluminium alloy, so that it can itself carry the required current. A matrix of storage elements, Fig. 4 (not shown), is formed by means of a corresponding plurality of magnetic films, and their associated insulating and conductive strips, the films 16À1, 16.2, 16.3 constituting the bit lines, and the conductive strips 26.1, 26.2, 26.3 constituting the word lines. The word lines are terminated with characteristic impedances 40.1, 40.2, 40.3, and appropriate conventional driving and switching circuits are provided. Undesired coupling between storage elements is reduced by slits 56 in the magnetic film 22. In a second embodiment, Figs. 5, 6, 8 (not shown), in which the magnetic films 16, 22 are parallel, inter-element coupling is reduced by longitudinal slits 56 in the film 22. To write a " 1" or " 0," a positive word pulse is applied to one or all of the word lines, and a positive or negative pulse, respectively, applied to the appropriate bit line, to magnetize the selected element in one direction or the opposite direction along its easy axis. To read out, a positive word pulse is applied the selected word line to magnetize the elements in that line in the hard direction, the pulse being large enough to permanently switch the element if destructive readout is required or small enough to only temporarily switch the element if non-destructive readout is required. The conductive strips may be of silver, gold, aluminium, or copper, and the magnetic material may be permalloy.

Title: A process and an apparatus for continuously separating mixtures of substances by fractional crystallisation
Inventor: FLEISCHER JURGEN
IPC: B01D9/00
Filed: 1963-04-03
Abstract: A mixture of crystals and mother liquor is introduced centrally to the top of a hollow drum-like apparatus, of short axial length compared with its diameter, rotating about its axis, orientated vertically.  Near the axis the upper and lower surfaces are of frusto-conical shape and are formed as filter surfaces 4, Fig. 1, (not shown) through which mother liquor passes.  The remaining mixture is then moved radially outwards by centrifugal force: the upper and lower surfaces of the apparatus converge slightly here. Near the periphery of the apparatus is arranged a heating device 6, extending around the inside, for melting the residue of crystals; the melting rate, and hence the rate of outward flow towards the heating device, may be adjusted by regulating the heat output of the heating device.  To the upper surface of the apparatus, at the periphery, is connected at least one duct which extends inwards at a small inclination for about two thirds of the radius and ends in an upwardly-directed discharge opening.  (Two ducts, 8 are shown in Fig. 1).  These are for discharge of part of the melted crystalline residue from the region of the heating device.  In a modification (Fig. 2 not shown), the apparatus comprises three cylinders symmetrically disposed and directed radially outwards (in plan) from a common axis of rotation.  Each cylinder has a portion of its surface, near the common axis, formed as a filter surface, has a heating device just inside its outer end, and has a small aperture at its outer end for discharge of part of the melted crystalline residue.  The apparatus may be used for separating xylenes or nitrochlorobenzenes or for recovering naphthalene from tar oil

Patent GB-978301-A (GB)
Title: Improvements in or relating to the automatic batching of bulk materials
IPC: B65B1/44
Filed: 1961-04-14
Abstract: 978,301. Automatic weight control. SCHWEIZERISCHE INDUSTRIE-GES. April 14, 1961 [April 20, 1960], No. 13436/61. Heading G3R. Equalisation of the differences in weight which occur in volumetric batching is effected by changing the volume of the batching chamber automatically whenever the weight of a predetermined number of filled containers exceeds, or drops below, a predetermined limit value. As shown, a container 7 is first filled from a hopper 1 by way of a batching chamber 2 the volume of which may be varied by a servomotor 3 and is then weighed on a machine 8 which supplies a voltage, representative of the weight of the container, to two analysing units 9 and 10. The unit 9 produces a signal when the container weight exceeds a certain upper limit, and the unit 10 produces a signal when the weight is below a certain lower limit. These signals are applied respectively to storage units 11 and 12 which each serve to actuate the servo-control 14 when a certain adjustable number of signals per unit of time is exceeded, whereby the servomotor 3 is started up to adjust.the volume of the batching chamber 2. A timing relay 13 determines the amount of the adjustment. Thus, units 11 and 12 may be adjusted to actuate the control 14 if, for example, ten or more of the filled containers are outside the upper or lower weight limit during a filling cycle of one hundred containers. If, say, eight containers are outside the limits, the servoarrangement does not respond. If, however, twelve containers out of the hundred are too heavy, the unit 11 actuates the control 14 so that the motor 3 acts to reduce the volume of chamber 2. If, on the other hand, more than ten containers are too light, then unit 12 actuates the servo-arrangement to increase the volume of the chamber 2. The units 11 and 12 may summate the signals qualitatively instead of quantitatively.

Title: Improvements in or relating to planes for aircraft
IPC: B64C9/18
Filed: 1928-05-09
Abstract: 299,274. Fowler, H. D. May 9, 1928. Planes, construction of; steering and balancing.-An aircraft plane comprises a cambered main portion, a trailing portion of smaller cross-section and an auxiliary surface adapted to be housed beneath the trailing portion and to be projected rearwardly and downwardly to vary the area and camber of the plane. Mechanism is provided for projecting and retracting end sections of the auxiliary surface in opposite directions when required to facilitate control. The main portion of the plane has front and rear spars 16, 17 connected by pressure ribs 18 and prevented from tilting by bracing 23. The under surface of the trailing portion is offset from the main under surface to accommodate auxiliary planes 28 carried by trolleys 29 running on curved rails 24 secured by brackets 25 to the rear spar 17. The rails 24 project through slots in the trailing portion. The trolleys are moved by endless cables 34 passed around pulleys 34 on the rails 24 and secured to drums on a vertical shaft 37 moved by a handle 33 in the central section of the plane. The cables leading to the two outer sections are secured to drums 36<a>, 36<b>, on a shaft 37a and sleeve 49, Fig. 11, and that from the central section is secured to a drum 36 on a sleeve 47 surrounding the shaft 37<a> and suspended from a bearing 48. The sleeve 49 has a gear 50 in mesh with a gear 71 on a shaft 69 which has a gear 68 meshing with a gear 67 on a third shaft 65. The gear 67 is in mesh also with a gear 63 splined to the shaft 37a when the parts are in the position shown. Movement of the handle 38 when the parts are in this position causes opposite rotations of the two drums 36<a>, 36<b> while the drum 36 remains stationary. By moving a lever 55, cams 54 on shafts 52, 56 cause a plate 60 to be raised to move the gear 63 out of mesh with the gear 67, and by raising the sleeve 49 and shaft 37<a> cause all three drums to be clutched together. Movement of the handle 38 under these circumstances causes all three drums to be moved together to vary the camber and area of the plane as a whole.
