Abstract: 897,789. Filters combined with gravityseparation apparatus. DOUGLAS, E. Nov. 23, 1960 [Aug. 26, 1959], No. 29145/59. Class 46. A mixture of oil and water is pumped (10) from a ballast or like tank 13 to a combined filter and settler 1 at 5. The mixture passes downwards through an array of concentric flow-stabilizing cylinders 9 and through a pebble-bed filter 3, upon which oil is deposited, the water being discharged at 19; the valves on oil discharge pipe 6 and air vent 7, and valves 16, 18 and 20 are all closed. To clean the filter bed, valves 14 and 19 are closed and valve 16 and the valve on pipe 6 are opened. Purging water is pumped from a branch 15 through valve 16, and oil floating in the apparatus 1 is discharged at 6. Next, valve 16 and the valve on pipe 6 are closed, and air vent 7 and a waste valve 18 are opened, the latter being closed when the water has drained to within 2 inches of the top of bed 3. With valves 18 and 19 closed valve 20 is opened and steam (and, optionally, air) is admitted from an inlet 22, followed by water from an inlet 21, the rate of flow being sufficient to fluidise the bed and the temperature of the bed being raised sufficiently to release oil adhering to the pebbles, the thus released oil being discharged at 6. Air and uncondensed steam escape at 7. Finally all air is ejected by filling the apparatus with purging water. On closing valve 20 and vent 7 and opening valve 19 the apparatus is ready to receive the next charge from tank 13. A steam heating coil 8 is located in the top of the apparatus.

Title: Magnetic memory
IPC: G11C19/10
Filed: 1965-07-12
Abstract: 1,091,566. Magnetic storage elements. SPERRY RAND CORPORATION. July 12, 1965 [July 28, 1964], No. 29535/65. Heading H1T. [Also in Division H3] A thin film magnetic storage element 10 has a drive winding 14 arranged at an angle to its easy axis 12 so that a D.C. bias on winding 14 causes the magnetization vector to align itself with the drive winding when one binary digit (" 0 ") is stored and to move further from such alignment when the other digit (" 1 ") is stored. To read out the information an A.C. signal of frequency f is superimposed on the D.C. bias so that the magnetization vector for a " 0 " oscillates on both sides of the drive winding, whereas the vector for a " 1 " remains always on the same side of the winding. Thus a stored " 1 " induces a signal of frequency f in an output winding 16, whereas a stored " 0 " induces a signal of frequency 2f. If the polarity of the D.C. bias is reversed a " 1 " will generate frequency 2f and a " 0 " f . The film element may be planar or may be formed on the surface of a wire with the easy axis skewed with respect to the axis of the wire. The wire substrate then constitutes the sense conductor. An additional drive wire may be provided for writing and it may lie parallel to the easy axis.

[Classes 44 and 65(i)] A device for maintaining open a sliding door 1, Fig. 1, which is urged by gravity or spring-means to the closed position, comprises a sliding bolt 4, one end of which engages 'the front edge of the door. The contacting door edge and bolt end may be roughened or formed with undulations to increase the friction between them, and on pressing the door back slightly the bolt is free to be retracted by its spring 14 and allow the door to close. The bolt slides on a stud 10 secured to the backplate 11 and a stud 9 which is mounted on one end of a bell-crank lever 12. For retracting the bolt 4 from a remote position by a cable system, mechanical linkage of rigid rods, pneumatically or electromagnetically, a connection is made to the free end 18 of the bell-crank lever 12 which is pivoted at 13 to the back plate 11. The slot 7 in bolt 4 allows the bolt to remain in retracted position after retraction by the lever 12 whilst the latter returns to its original position. When applied to a hinged door 1, Fig. 5, the bolt 4 engages a face of the door adjacent its edge, the plate 11 being mounted on a block 26 secured to, or integral with, the wall 3.

A sewing-machine with a needle-bar guide mounted for oscillation about a vertical axis, so that the needle-bar can be moved transversely to the line of feed, has means for securing this guide in a median position for straight sewing and has provision for applying removable mechanism which is capable of automatic movement of the needle-bar guide for zig-zag and like sewing and which may also vary the direction and amplitude of the feed movement for the production of more complicated ornamental stitching. In the form shown the needle-bar 7 works in a gate 9 which is mounted on a vertical spindle 10 and has a lug 16 for attachment of needle-vibrating mechanism ; for straight sewing the gate 9 is held in a fixed position by a spring 11 pressing it against the head of a screw 89 screwed into a fixed part, this screw being slacked back to free the gate when required and being locked by a counter-screw. The feedmechanism is as described in Specification 683,292, controlled in amplitude and direction by the angular position of a diametrical guideway in a member on the lower end of a vertical shaft 55; this shaft, in the form shown, is held in adjusted position by friction produced by a spring 86, and is moved angularly by a lever 82 between adjustable limits imposed by a pointed screw 85 engaging the edges of a notch in the hub 83 of the lever 82 on the shaft 55. For conversion to automatic operation, a fixed cover 87 carrying the feed control screw 85 is removed, together with the lever 82 and spring 86, and replaced by the parts shown in Fig. 11, including a fixed mounting 49, control lever guides 46, 71, and a hinged cover 2 which together fill the opening left by the cover 87. The added mechanism is substantially the same as the mechanism described in Specification 683,291, differing only in that the adjustable stops 75 controlling the feed-control lever 68 slide on the member 71 and are screw-clamped thereto, in the form of the finger-arm of the lever 68, and in that the pin 58 of the feed-control mechanism engages a fork in the member 56 on the shaft 55 instead of a single abutment surface thereon. In a modified form of the machine in its non-automatic form, the feed-control lever 68 and associated parts as shown in Fig. 11 are used in place of the corresponding parts in Fig. 10, the hinged cover 2 is retained, and a fixed blank cover member fills the place of the members 46, 49; the head of the needle-bar gate securing screw is replaced by a pair of lock-nuts.

According to the invention additional navigational information is transmitted as a modulated pulse signal, derived coherently before modulation, on the carrier wave frequency of the pulse pairs associated with and spaced from each of the pulse pairs so as to lie coherently in the interval between the pulse pairs and the pulse signal is decoded on the aircraft. The description comprises a system in which a TACAN normal or sector beacon (A) is located at one end of a runway and a beacon (E), affording elevation data, is spaced transversely from the intended touchdown point. A third pulse is generated at E by delaying a decoded pulse pair from A by a fixed interval #t. Information may be binarily coded utilizing a fourth pulse.
