Title: Improvements in or relating to devices comprising magnetic cores
IPC: H01F1/03
Filed: 1954-01-04
Abstract: 740,304. Magnetic structures. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 4, 1954 [Jan. 7, 1953], No. 208/54. Class 38 (2). So that it may have a rectangular hysteresis loop a ferromagnetic ferrite core has provided on at least part of its surface a layer of glass, enamel or other ceramic material having a specific resistance greater than 10 ohm/cm. and a mean coefficient of expansion in the temperature range between room temperature and the temperature at which any part of the structure softens, differing from the mean expansion coefficient of the ferromagnetic material in the same temperature range, the layer being applied in such a manner that the expression #D - #O / #O measured at any section of the core has at the most half the value it would have in the absence of the layer. #D and #O are respectively the values of flux across the core section at maximum flux and with magnetizing force reduced to zero. Fig. 2 shows an annular core 2 of nickel zinc ferrite, to the opposite sides of which glass rings 1 are affixed by layers 3 of enamel. The structure is heated to the temperature at which the enamel becomes liquid, and after 5-10 minutes cooled slowly. At room temperature the glass rings exert anisotropic compression on the core 2 which makes its hysteresis loop more rectangular. Alternatively the annular ferrite core may be surrounded by a glass ring which is shrunk to fit the core at 700‹ to 800<SP>o</SP> C., the compressive stress developing as the structure is slowly cooled, Fig. 4 (not shown). In ferrite core 11 of Fig. 5 the compressive stress is developed at a narrow portion created by grinding off segment 12, by a glass strap 13 baked on to the core by enamel. Specifications 684,043 and 693,81.7 are referred to.

Filed: 1959-01-02
Abstract: 883,996. Feeding sheets. GOLDING, W. F. Jan. 1, 1960 [Jan. 2, 1959], No. 246/59. Class 100(1) In sheet feeding apparatus, sheets are fed sequentially to front lays 17, 18, 21, 22 on a table 10 which is mounted for oscillation in bearings 13, 14, and the lays can be adjusted in a direction at right angles to the axis of oscillation of the table by rods 33, 34 which pass through the bearing 14. The lays, and sheet-detectors 19, 23, are each secured to a rod 30 slidable beneath the table 10 in guides 31, and spring-urged against a ramp 32 secured to one of the rods 33, 34. The rod 33 is slidably mounted beneath the table in guides 35 and passes through the table bearing 14 where it is engaged by a screw 39, and is urged against the screw by a spring so that any adjustment of the screw moves the ramps 32 and adjusts the position of the lays 21, 22 and sheet-detector 23. Similarly, the rod 33 is adjusted by a screw 38 to adjust the lays 17, 18 and sheet-detector 19. The registered sheets are carried away by grippers 25 on endless chains 26, and the table 10 is rocked downwardly to allow this sheet-delivery. Since the arcuate movement of the screws 38, 39 is small when the table 10 oscillates, the front lays can be adjusted during the sheet feeding operation. Any one of the front lays can be rendered inoperative by pulling it away from the table against the action of the spring-urged bar 30, and moving a headed pin into the space between the table and lay. Sheet-detectors. The adjustable sheet-detectors 19, 23 are electrically conductive knive-edge contacts arranged at the level of the upper surface of the table 10 and a short distance behind the front lays, and further contacts (61, not shown) are arranged above, and are adapted to be moved downwardly towards the contacts 19, 23 every time a sheet is supposed to be present at the lays. If a sheet is absent at the lays, or not close up to all the lays, the contacts meet, and the electric circuit of the drive to the machine is disabled.

Abstract: 650,322. Folding and variable camber wings for aircraft. ROBERT, R. A. Jan. 5, 1948, No. 280. Convention date, March 11, 1947. [Class 4] A foldable wing for aircraft is characterized in that it is rotatively mounted on the fuselage and comprises a plurality of elements disposed spanwise side by side, and that the wing may be folded in such a manner that in folded position adjacent elements will be retracted one wholly or partly within another. A folding wing of the type described in Specification 628,047 comprises three spanwise elements 60, 61 and 62 (shown in Fig. 3 in the normal position I, a partially folded position II and the fully folded position III), the element 60 forming the load-carrying member, and comprising a spar 63 supporting intermediate ribs 64 and a tip rib 65. A tubular member 66, pivotally mounted at 67 on a vertical axis to the rib 65, forms the main structural member of the element 61 which is provided with an end rib 76 to pivotally support at 75 a tubular member 74 which constitutes the main member of the element 62. Relative twisting movement between the members 63, 66 and 74 is prevented by one or more pairs of collapsing links 77, 78 pivotally connected thereto. The spar 63 is pivotally attached to the fuselage on a vertical axis 56 to enable the wing to be folded by a pair of telescopic screws 96 symmetrically arranged about the chordal datum of the wing and arranged to be enclosed within the depth thereof. The element 62 may be partially collapsed within the element 61 and that partially within the element 60 by rotation about the axes 67 and 75 respectively before the wing folding operation takes place or, as shown, the elements may be collapsed automatically during the folding operation. To effect such automatic collapsing one arm of the link 77, pivotally mounted on the spar at 80, is extended by an arm 81, the extremity of which is connected to a resilient link 83 pivotally connected at its inner end to the fuselage of the aircraft. The links 77 and 78 are interconnected by arms (Fig. 15, not shown), to ensure that they open or close simultaneously. In a further embodiment (Fig. 14, not shown), the elements 61 and 62 may be used as flaps in which case the sleeves connecting the links 77 and 78 to the tubes 66 and 74 are mounted on bearings and the ends of the tubes are rotatively mounted on fittings pivotally attached to the end ribs 65 and 76 respectively. The tubes 66 and 74 are provided with arms each engaged by a screw and nut mechanism mounted on appropriate members of the links 77 and 78 and interconnected by chain and sprocket gearing driven by an electric motor so that the elements 61 and 62 may be deflected simultaneously with respect to one another and the element 60.

Title: Improvements in or relating to air-cooling apparatus
Filed: 1949-01-12
Abstract: 670,638. Cooling air. STEVENS, A. H. (Pennington, N. A., Hoar, R. S., and Henley, R H.). Jan. 12, 1949, No. 836/49. Class 64(i) An air stream flowing to an enclosure through a passage 15 is cooled by transference of heat to another air stream flowing in a second passage 19 by means of a rotatable heat-transfer wheel 38 which has sectors of air-permeable non-hygroscopic heat absorbent material and rotates so that each sector moves successively across each passage, and the second air stream is cooled by evaporation of water in it before it reaches the heat-transfer wheel 38. In the form shown, air drawn by a fan 17 from a room through the passage 19 is cooled by evaporation of water absorbed by a packing of excelsior or other material in a rotating wheel 32 with sector-shaped openings in'its sides, the lower part of this wheel being immersed in water 35. The air-stream so cooled cools the sectors of the wheel 38, which in turn cools the air stream propelled by the fan 14 through the passage 15 into the room. The wheel 38 is divided by radial partitions into sectors filled with aluminium wool, copper wool, or zinc wool. In a modification, part of the cooled incoming air stream in the passage 15 is byepassed into the outgoing air stream in the. passage 19. In another modification, two wheels like 32 on. a single shaft are provided to cool the air drawn from the room, and two wheels like 38, also on a single shaft, are provided to cool the other air stream. In a third form, Fig. 13, air drawn from a room flows through three stationary pads 90, 91, 92 which are kept wet by water pumped from a tank 93 to troughs 97 and allowed to drip on to them, surplus water returning to the tank 93 through pipes 99. This air stream is initially cooled by a rotating wheel 89 containing heat absorbent material. Two similar rotating wheels 87, 88 cool the air stream in the passage 75. In any form, a stationary evaporative pad may replace a rotating evaporative pad, and vice versa.
