Abstract: 812,570. Lubricating; making bearings. FLUIDWICK CO. Inc. Aug. 7, 1956 [Aug. 5, 1955], No. 24222/56. Classes 12 (1) and 12 (3) A wicking material especially for storing lubricant for shafts, porous bearing sleeves and the like, is made from cellulose wood fibres, the bulk of which are shorter than three millimetres and which have been soaked with a lubricating oil in an amount at least 5 parts of oil to 1 part of cellulose material by weight. These fibres may be made from wood fibres and a mixture of paper-containing fibres of wood, cotton and the like which are macerated to produce material in lengths of from 0.5 to 2.0 millimetres. They retain the oil to such an extent that they can be injected under pressure into a cavity in a bearing and they can hold up to 10 parts of oil to 1 part of cellulose material. In the construction shown, apparatus is provided for fitting a porous sleeve 5 into a bearing body 3 and for supplying wicking material to a recess 6 in the body 3. The body is placed over the end 8 of a nozzle 9 which projects through a hole in a bed 12 and is connected by a flexible tube 11 to a mechanism for injecting wicking material 7 under pressure. The bed 12 has a stirrup 13 containing a spring 2, which surrounds the nozzle 9 and at one end engages the stirrup and at the other end engages a collar 15 adjustably secured to the nozzle. The upper part of the nozzle has transverse passages 18, 19 located opposite the recess 6. The initial operation of a ram 21 operates a lever 22 which actuates mechanism to discharge a metered amount of wicking material 7 from passages 18, 19 into the recess 6. Further movement of the ram presses the sleeve 5 into the bearing body 3.

Filed: 1963-06-13
Abstract: 1,102,473. Programmed control of distribution. P. E. CONSULTING GROUP Ltd. July 29, 1964 [June 20, 1963], No. 24632/63. Heading G3N. [Also in Division A4] A system for the automatic selection and distribution of goods in bulk is responsive to data on a record media indicative of location, quantity and destination of goods, to control the movement of a trolley and, on transfer of goods to a conveyer associated with the trolley, the passage of a predetermined quantity of goods to a selected one of a plurality of reception channels. As shown, a trolley 5 is positioned adjacent to a desired section of a storage rack 15, 16 under the control of a memory and controller 4 responsive to signals derived by a reader 2 from a record tape 1 bearing information related to desired items, their quantities and branches to which despatched. The memory contains information to the section of the rack occupied by the different items. The read information is also recorded on a slave recorder 3. A handler on the trolley, in response to a visual indication, removes the items and places them on a conveyer 6 mounted on the trolley which transfers the items to a conveyer 12. In the event of the number of the items available in a section being less than the desired number, the handler presses an "over-ride" button to read the memory and move the trolley to a further section; if the item is available in the further section, the first section is erased from the memory. In the event of the stock being less than the desired quantity, a signal is sent to the slave recorder 3. The items on the conveyer are counted by a photo-electric device 19 and compared with the desired number before release to the conveyer 12. A slave reader 8 reads the data on the slave tape and controls a selector 9 to actuate, through a magnetic drum delay device 14, a plurality of ploughs deflecting the items into despatch bays 7. Signals from the master reader 2 are processed in an electronic sorter 17 to cause indicating lights 18 to display the dispatch indications to handlers at the bays 7.

Abstract: 691,454. Tyre-building. WINGFOOT CORPORATION. Oct. 23, 1951 [March 26, 1951]; No. 24695/51. Class 144 (i).  Stretchable strip material, such as a chafing strip 9, fed to the side wall of a tyre carcase 4 is applied thereto by mechanically stretching the radially outer edge portion of the strip and pressing it against the tyre carcase. As shown, the stretching of the radially outer edge portion is effected by threading the strip around two knurled rollers 5, 6 which are shorter in length than the width of the strip and have different peripheral speeds of rotation so that the material between the roller is stretched. In a " crown " drum building machine strip applying rollers 5, 6 are arranged at each end of the drum 3, each set of rollers being mounted on a pivoted frame 13 which can be swung away from the drum 3 against a spring 24. The frames 13 are adjustable axially of the drum for different drum lengths on a support 19 which is vertically adjustable for different drum diameters. The roller 5 is arranged to press against and be driven by the tyre carcase 4 and the roller 6, which is spaced from the roller 5 and tyre 4, is driven via a gear 10 from a gear 11 on the roller 5. The peripheral speed of roller 6 is arranged to be slower than that of the roller 5 by suitable choice of roller diameters or of the gears 10, 11. A guide 22 provided with a strip-edge locating band 23 may be fitted to each frame 13. Fig. 1 shows two arrangements of the strip 9 around the rollers 5, 6 for different rotational directions of the drum, the two arrangements being used for successive applications of the plies of a two-ply strip. In an alternative arrangement the strip 9 may be arranged as in Fig. 7, the rollers 5, 6, having the same direction of rotation by the insertion of an idler gear between the gears 10, 11.

A tubular metal enclosure for an electrical discharge device is formed of a series of tubes connected mechanically end to end, the tubes being separated electrically by gaps extending annularly about the axis of the tubes, the ends of the tubes adjacent the gaps overlapping in a direction along the axis and forming with interposed electrical insulation a vacuum seal around the outsides of the gaps, and electrical insulation adjacent the inner face of the enclosure sealing the gaps against the entry of arc spots. Fig. 3 shows how a pair of adjacent sections can be connected. The wall 3 of the upper section has a longitudinal extension 5 and the wall 4 of the lower section has an extension 6, the extensions 5 and 6 overlapping to form a longitudinally extending gap. Flanges 8, 9 of the two sections are clamped together by a clamping ring 10 with interposed insulation 12, which may be a porcelain ring, with vacuum sealing rings in the faces of the flanges which are pressed against the ring 12. An insulating ring 13 is provided at the inner end of the gap to prevent arc spots entering the gap. The enclosure may be toroidal and form a thermonuclear apparatus.

Abstract: 909,013. Radioactive measurements in flowmeters. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 3, 1961 [July 15, 1960], No. 24827/60. Class 40 (3). [Also in Group XXIX] A flowmeter comprises a pipe 1 containing at least one hinged vane 5 adapted to be deflected from its rest position by the flow of fluid along the pipe, a radioactive source 6 mounted on the vane, and a radiation detector 7 mounted outside the pipe such that the distance between the source and detector varies with the deflection of the vane. Where it is desired to measure the actual flow rate, the detector may be located as at 7 a distance downstream from the vane approximately equal to the radius of movement of source 6. Where the requirement is merely to detect a change in flow rate, the detector may occupy the position 29 on the lower side of the pipe in the near vertical position of the vane. Cobalt 60 or caesium 137 are referred to as suitable materials for source 6 and a cadmium sulphide crystal for the detector, although reference is also made to the use of a scintillation detector. To extend the operating range, an arrangement, Fig. 3 (not shown), using two overlapping vanes, one of smaller area and greater mass than the other, may be utilized. Correction of non-linearity of measurement may be effected by use of detector crystals of suitable response, and line instead of point radiation sources. A further arrangement for extending of operating range, Fig. 5 (not shown), involves three flowmeters of the construction shown in Fig. 1 arranged along the pipe, the three vanes being of different areal value, and the associated detectors being connected to an indicating meter via a switch for selecting the output of any one at a time.
