Title: Magnetic coding devices for movable bodies
IPC: B61B10/00
Filed: 1972-05-09
Abstract: 1393973 Discharging articles from endless conveyers JERVIS B WEBB INTERNATIONAL CO 9 May 1972 [10 May 1971] 21499/72 Heading B8A [Also in Divisions G4 and H1] A magnetic coding device for a movable body comprises a selector and a code reader, the selector being mountable on the movable body and registerable with the code reader which is mountable along a path of travel of the movable body, the code reader comprising a group of polarized electrical contacts arranged in code positions having the poles thereof alternately opposite, the selector comprising a selector member, at least one pair of magnets movable therewith into a selected one of a plurality of code positions, at least one of the magnets in each of the code positions being capable of activating one of said polarized electrical contacts when the selector is in registry with the code reader. The polarized electrical contacts in the code reader are ten reed contact-pairs, equally spaced around a circle and each biased by a respective magnet, these being alternately oriented going round the circle. The selector member bears two magnets, oppositely oriented, at respective positions 144 degrees apart on a circle of the same diameter, and rotatable to one of ten positions, so that when the selector is in registry with the code reader, these two magnets are aligned with respective magnets of the code reader, reinforcing one and opposing the other. The pair of reed contacts associated with the reinforced magnet close to identify the body carrying the selector, to control switching, tipping, ejection or stopping in the application where the body is a container or object on a conveyer, there being code readers spaced along the conveyer. Account of the reading is taken only if two further biased reed contact-pairs are closed by respective magnets on the body, to avoid incorrect readings due to imperfect registration. Fig. 7 shows an arrangement for moving the inoperative magnet in the selector member radially inwards to be shielded by two polepieces 23 (only one shown). The two magnets 21, 22 are carried by a support 24 pivoted to two arms 25 (only one shown) fixed on shaft 20a which rotates with the selector member, so that as the shaft rotates a follower 26 fixed to support 24 follows the star-shaped track between two cams 27, 28 so that the support 24 oscillates radially. Thus for successive ones of the ten angular positions of the selector member, the two magnets 21, 22 occupy the outer (or inner) position alternately. A ratchet is provided on shaft 20a to define the ten positions. The above arrangements are for one decade. Other decades can be provided also. As the selector moves into registry with the code reader, guides produce registration in the two directions orthogonal to the direction of relative movement.

Title: Improvements in or relating to coil constructions for goniometers and the like
IPC: G01R25/00
Filed: 1945-08-23
Abstract: 620,480. Phase difference and power factor measurement. O'BRIEN, W. J. Aug. 23, 1945, No. 21665. [Class 37] A phase meter or comparable instrument is characterized by a field structure which comprises a main frame defining an axis of rotation and having two pairs of field coils mounted coaxially thereon at right angles to one another and equidistant from said axis of rotation. As shown in a preferred form for inclusion in a registering goniometer the field structure is made up of a moulded rectangular frame 36 having a central bore 43 for a permanent magnet rotor 26 and four radially extending ribs 44-47, one from the centre of each side face thereof, to provide seating surfaces for four identical rectangular coil bobbins 37a, 37b, 38a, 38b, the dimensions of which are so chosen in relation to each other and the frame 36 that one pair of coil bobbins 37a, 37b disposed vertically against the opposite faces of ribs 45, 47 overlaps and is locked to the other pair of coil bobbins disposed horizontally against ribs 44, 46. The width of the ribs 45, 47 may be such as to space apart the centre of each pair of coil bobbins a distance equal to the identical effective radius of each coil bobbin. The assembled positions of the coil bobbins form a square hole at each end of the field structure through which extends the rotor shaft 7 which, as shown, drives a system of differential gearing similar to that in an electric supply meter to indicate the accumulative angle change between potentials applied to the respective pairs of field coils. In a modification a rotating coil structure wherein the coil is housed in recesses within a rectangular moulded block, Fig. 6 (not shown), supersedes the permanent magnet rotor 26. Specification 620,507 is referred to.

Title: Method of recovering crude oil from a subsurface reservoir
Inventor: DUMORE JOHANNES MARINUS
IPC: E21B43/16
Filed: 1962-06-05
Abstract: 933,906. Wells. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. June 5, 1962, No. 21742/62. Class 85. A method of recovering oil from a subsurface dipping reservoir having an injection well and a production well comprises feeding into the injection well a drive mixture of methane and one or a mixture of intermediate paraffinic hydrocarbons having 2-6 carbon atoms per molecule to give a mean superficial rate of flow in the reservoir lying between 1 and 3 times the critical rate at which a methane drive tends to finger into the oil. The drive mixture composition is found by experiments with test tubes filled with a sand pack saturated with oil having the characteristics, temperature and pressure of the reservoir oil. In a given recovery the intermediate hydrocarbon in the drive mixture is propane which is available as a percentage of the pore volume of the reservoir so that methane may have to follow the drive mixture as a scavenging fluid. The desired mean superficial rate of flow in the reservoir is known, the critical rate for the reservoir is calculated, and hence the ratio mean superficial rate to critical rate is calculated. This ratio is used to calculate a rate of superficial flow for drive mixtures through the test tube after the critical rate for the tube is calculated. Various compositions of drive mixture are separately injected into the top of the test tube, and if an available drive mixture is less than one pore volume the mixture is followed by methane. The quantity of oil produced by each drive mixture is measured at the moment the mixture is withdrawn from the lower end of the tube, or at the moment the cumulative volume of the drive mixture, or drive mixture and methane, equals one pore volume of the sand pack. The quantity of oil produced as a percentage of the pore volume of the pack is plotted against the amount of propane in the drive mixture as mole per cent to enable the composition for maximum recovery from the tube to be found. A drive mixture of this composition (followed, if necessary, by methane) is injected into the reservoir through a well at the crest, and oil is produced from a well on the down dip side.

Title: Food package
IPC: B65D81/34
Filed: 1964-05-26
Abstract: Packages (see Division B8) suitable for heating in an electric toaster contain bacon-like slices made from natural vegetable protein held together by an edible binder.  The vegetable protein may be molecularly oriented man made fibres of protein, for example, spun and stretched soybean or sesame seed protein fibres, 3/4 "-5\yF in length containing 60% moisture and having pH 5.9.  The binder is preferably an aqueous dispersion of albumin and an alkali metal or alkaline earth metal soya proteinate, such as sodium, potassium or calcium soya proteinate.  A suitable binder is made by mixing together neutralized soya sodium proteinate binder, albumin, autolyzed and hydrolyzed yeast extract (with salt, spices and vegetable extract (celery and onion) added), monosodium glutamate, smoked torula yeast (with hydrolyzed vegetable protein and salt added), vegetable gum, red colouring, caramel and water.  The vegetable gum may be guar gum, locust bean gum or a seaweed extract. Maize oil is added to the binder and mixed in.  The protein fibres are then mixed in, and the dough rolled into a layer about 3/8 " thick.  A similar layer is made with the exception of the red colouring, and a bacon like slab is built up of alternative red and white layers.  The slab is set by placing in an oven for about 70 minutes at a temperature of 165 DEG F., and is then sliced and smoked.  The slices are dehydrated so that their moisture content is between 5% and 9% by weight. This can be done by convection currents in a hot oven (500 DEG F.), by an infra-red heater, or by subjection to a moving stream of nitrogen.  The slices are then ready to be packaged.

Abstract: 409,953. Supports for electric incandescent lamp filaments. MAYER, H., 47, Corringham Road, Golders Green, London. Aug. 3, 1933, No. 21855. Convention date, Dec. 10, 1932. [Class 39 (ii).] A filament support for tubular electric incandescent lamps comprises a wire a, Figs. 1 and 2, which extends longitudinally within the tube e without touching the wall thereof, and is bent from side to side into a succession of zig-zags or wave forms throughout its length. Preferably the zig-zagged supporting-wire a is of flattened crosssection, with the greatest dimension at right angles to the plane of the zig-zags, glass beads b being fused in known manner at spaced points c<1> on the wire to receive struts c with coiled ends to engage the turns of the helical filament f. Wire struts d which are successively displaced relatively to each other by an angle of about 120‹ may also be attached to the glass beads b, the uppermost struts being curved so that their outer end portions are at right-angles to the wall of the tube, as shown in Fig. 4. The lengths of the struts d are such that they maintain the filament centrally along the axis of the tube. These struts may be dispensed with when the tube is sufficiently short for the tension upon the wire a to maintain the wire clear of the tube wall. Before it is mounted within the tube the zig-zagged wire a is about two-thirds of the length of the tube, and has the filament f hooked upon the struts c, so that after insertion within the tube the supporting-wire can be pulled to the requisite length, thereby tensioning the filament. Preferably the zig-zagged wire a is of non-resilient metal.
