Title: Improved magnetic data storage element
IPC: H01F10/10
Filed: 1965-09-01
Abstract: 1,088,470. Magnetic structures. SPERRY RAND CORPORATION. Sept. 1, 1965 [Sept. 29, 1964], No. 37264/65. Heading H1H. Magnetic thin films for memory purposes are shaped so that (a) in the case of a straight-edge film the angle between a straight edge and the easy axis of magnetization is less than 45 degrees, and (b) in the case of a curved edge film the angle between the tangent at any point and the easy axis is less than 45 degrees. This shaping of the film prevents the undesirable effects of demagnetizing fields which arise due to free poles at the edges.

Title: Improvements in or relating to an acoustical tile

IPC: C04B26/28
Filed: 1960-11-01
Abstract: 916,710. Acoustic tiles. NATIONAL STARCH & CHEMICAL CORPORATION. Nov. 1, 1960, No. 37568/60. Class 140. An acoustical tile contains a fibrous base and a binder comprising amylose, as herein below defined, in an amount within the range of 0.9 to 50% based on the total weight of the fibrous base. The term "amylose" includes pure amylose resulting from the fractionation of starch; amylose present as a component of an unfractionated high-amylose starch containing 50% or more amylose; or amylose from either of these two sources which has been chemically derivatized by etherification or esterification so as to increase its water dispersibility. Specified fibrous materials are glass wool, mineral wool, wood pulp and bagasse. The binder may consist essentially of the said amylose or may comprise a mixture of starch and the said amylose. Amylose may be dispersed in water by heating under superatmospheric pressure and high temperature or it may be treated to render it more readily dispersible by reacting with an etherifying or esterifying agent to introduce a controlled amount of substituent groups. Tiles may be made by mixing the binder with water, heating the mixture, adding mineral wool thereto, pouring the resulting viscous mass into trays and heating these in a forced air-drying oven.

When the component 1 does not include a steel sole 12 a pressure resisting insert (not shown) is positioned beneath the edge of the steel toe cap 13. When the upper 5 is lined the shoe is made by lasting the lining 6, 7 to an insole 8 and then side lasting an upper 5 which has the toe and counter regions cut away as shown in Fig. 2. The metal elements are then assembled on the last and the outsole, toe-cap and counter assembly is then directly moulded onto the shoe using an injection mould as shown in Fig. 4. In a modification the moulded component including the metal elements is pre-moulded, and the pre-moulded component is stuck to the lasted upper 5 and lining shown in Fig. 2. Alternatively an unlasted upper can be sewn or welded to the pre-moulded component and the insole inserted at a later stage. The above procedures can be applied to the manufacture of an unlined upper, in which case the upper is complete in the toe and counter regions.

Abstract: 1320610 Fuel injection pumps; regulating I.C. engine fuel injection ALLIS-CHALMERS CORP 16 Aug 1971 [19 Aug 1970] 38332/71 Headings F1A and F1B An in-line fuel injection pump has a control rod 14 which executes both axial and angular movements under the control of a load and speedresponsive governor, the rod movements being transmitted into angular and axial movements of sleeves 9 controlling the opening and closing of spill passages 7, 8 in the pumping plungers 3 and thus the injection quantity and timing. Motion of the rod 14 is transmitted to the sleeves 9 through fingers 12 having spherical ends 68 each engaged in a transverse bore 13 in the rod 14. During the suction strokes fuel supplied by a feed pump 125 to a housing 63 enters the pumping chambers 24 through passages 7, 8. Injection commences when each passage 8 passes above the lower edge 22 of its sleeve 9, hence the axial position of the sleeves determines the timing. The quantity delivered is varied by the rotation of the sleeves altering the point that delivery is terminated. This termination occurs when each passage 8 registers with an open-ended helical groove 10 in the inside of its sleeve 9. In an alternative, Fig.7 (not shown), each passage 8 is provided with an enlarged triangular port (28) having an inclined upper edge which registers with a radial hole (30) through its sleeve. To accommodate manufacturing tolerances a shim 5 of selected thickness is inserted between each plunger 3 and its follower plate 4, the shim being located in a groove in the plunger 3. Each shim 5 has a forked end which receives an eccentric pin 6, on a calibration screw 32 rotatable to adjust the angular position of its plunger relative to its sleeve. The governor controlling the rod 14 is described in Specification 1219477.

[Also in Divisions B5 and F2] Pipe bends, or covers for pipe bends, of parttoroidal configuration, are made from blanks of plastics or metal which blanks are deep drawn between male and female dies having cooperating surfaces which are developed directly from the bend to be produced. If, as in the example illustrated in the Figures, it is desired to form a quarter toroidal bend, a surface 8 having the shape of the bend is constructed and then slit at 7 along its inner radius. The surface is then drawn apart in the direction of the arrows 9 until a surface having no re-entrant parts is formed (see Fig. 7). This surface is then used to construct the moulding dies from which blanks having a like shape are drawn. Extra marginal edges are provided on the blanks so that when the blanks are deformed back into the quarter toroidal shape from which they were derived they may be easily welded along their inner radii. Half toroidal bends, or toroidal bends of any fraction less than a half may be made by developing suitable blanks by the cutting and stretching process described above.
