IPC: B24D9/08
Filed: 1965-05-06
Abstract: 1,058,502. Abrasive tools. MERIT PRODUCTS Inc. May 6, 1965, No. 19214/65. Heading B3D. An abrasive tool comprises a rotary drive member 26 having a socket formed of a non- circular drive structure 44 which is adapted to receive a non-circular hub structure 48 united with an abrasive disc 20, the drive structure and hub structure being axially engageablo and separable in a first relative rotary position in which the hub structure is loose with respect to the drive structure and being rotatable to a second relative position which is a limit position and in which position shoulders on the drive member and hub structure are positively engaged to prevent axial separation of the member and structure. The abrasive disc 20 consists of a layer of fabric on which is bonded a layer of abrasive particles and a backing layer of fibreboard. The hub structure 48 (Figs. la and 2) is of plastics material and of annular shape, the inner bore of the annulus being a snug fit on a boss (35) extending from the drive member and the outer surface being of hexagonal shape. The annulus is formed with slots (54) to provide six segments each of which has surfaces (60, 62) and the inner surfaces of the segments are provided with inwardly-extending flanges 50. The drive member has a circular body 28 secured to an elastomeric flange 30 for backing the abrasive disc. The body 28 has a sleeve 44 which forms the non-circular drive structure and has six recesses (45, Fig. 2) forming projections (46). When the abrasive disc is presented to the hub structure, the segments embrace the boss 35 and the flanges 50 enter a groove 36 therein. When the disc is rotated relative to the drive member surfaces on the projection on the sleeve engage the surfaces on the segments 55 to retain the flanges in the groove to lock the disc to the drive member. In another embodiment, the sleeve 44 is replaced by a series of pins (65, Fig. 3a). In a further embodiment, the sleeve has an oval opening and the hub structure is oval, Fig. 5 (not shown). In another embodiment in which locking is effected in only one direction of rotation, the sleeve 44c, Figs. 6 and 7 (not shown), has recesses 74 having radial 78 and inclined faces 80 and the hub structure has segments having similar faces 75, 76 so that in one limit position the inclined faces engage to lock the disc to the drive member and in the other limit position, the radial faces abut but permit axial separation of the hub and drive member. In another embodiment, the drive member 84, Fig. 9 (not shown), carries a magnet 92 within a sleeve 88, Fig. 11 (not shown), of hexagonal shape, and the abrasive disc 86 has a stamping 97 having a flat wall 98 to lie against the wall and a hexagonal peripheral wall 100. The drive structure also has a pin 95 carrying a head 96 of triangular configuration which can pass through a triangular shaped hole in the wall 98. In use, the wall 100 abuts the sleeve 88 and the triangular head is displaced relative to the hole to prevent axial separation of the disc and drive member.

Title: Improvements in or relating to thin-film electrical resistors
Inventor: PRICE JAMES RUSTON
IPC: H01C17/24
Filed: 1963-05-16
Abstract: 991,056. Resistors. ALMA COMPONENTS Ltd. April 15, 1964 [May 16, 1963], No. 19486/63. Heading H1S. A thin-film resistor of a selected ohmic value comprises a spiral resistive path formed in a conductive film 3 deposited on a tubular non- conductive substrate 1, the path having an ohmic value slightly less than the selected value of the resistor and extending the full length of the film 3, and a further spiral resistive path formed in a conductive film 6 deposited on a tubular non-conductive substrate 4, of smaller diameter than the substrate 1, the further resistive path having an ohmic value equal to the difference between the selected value and the measured value of the first resistive path, the substrate 4 being mounted within the substrate 1 and the two resistive paths being connected in series. The substrates 1, 4 may be made of glass or a ceramic. The spiral resistive paths are made by cutting spiral tracks 2, 5 in the conductive films 3, 6, respectively. A conductive end cap 7 is soldered to or pushed over each end of the main resistor, one end cap having an aperture 8 to admit the secondary or padder resistor. The inner end of the padder resistor is provided with an end cap 9 to which a lead-out conductor 10 is led through the tubular substrate 4. A close tolerance resistor of the above type can readily be produced without the necessity for controlling the cutting of the spiral resistive paths with such accuracy as would otherwise be required. In addition, substantially equal power distribution throughout the length of the whole resistor is obtained and, if the temperature coefficient of the padder resistor is inferior, i.e. outside normally accepted tolerance, it will play only a small and insignificant part in the temperature coefficient of the whole resistor.

Title: A method of gasifying fuel oils containing vanadium and alkali
IPC: F23C99/00
Filed: 1961-06-02
Abstract: In the gasification of fuel oils containing vanadium and alkali compounds, the gases formed are conveyed over a curved path during or after gasification, whereby particles containing the vanadium and alkali compounds are separated by centrifugal force, the temperature being maintained at such a value that the compounds are present to a small extent only in the gaseous state.  This is ensured by maintaining a temperature of not more than 800 DEG  C. at the exit of the reaction chamber 1.  Oil to be gasified enters at 7 and air and/or oxygen, or steam is injected through nozzles 6, an impeller 10 causing the gases to follow a curved path in the chamber 1, the compounds, which exist as <PICT:0962001/C4-C5/1> molten ash, being deposited on the chamber walls.  In addition, a cyclone separator may be provided downstream of the gas outlet 8, or a ceramic filter may be located in the outlet 8.  In an example, a fuel oil Hu=9800 kcal./kg. was gasified to produce a gas of the following composition, percentages by volume: 6.9% CO2, 14.5% CO, 4.0% H2, 3.6% CH4, 2.0% hydrocarbons, 69.0% N2.

Filed: 1929-07-01
Abstract: 335,898. Triggs, W, W., (Accounting & Tabulating Machine Corporation). July 1, 1929. Transfer mechanism,-Keys control the setting of mechanism movable from row to row to set a battery of punches for perforating record cards, and simultaneously to set mechanism giving a visual indication of the punches set; the keys may also operate a printing device and an adding device which accumulates the items recorded by the punches. Keys 91 actuate rods 92, e.g. wires enclosed in flexible tubes 93, to operate levers 65 and punchsetting pins 71 which are caused to actuate each row of setting bars 78 in turn, as the travelling frame 74 on which the lever is pivoted is given a step-by-step motion: The bars 78 are slidable in a fixed frame, and notched to form cam latches for shifting and being held by a latch plate. Any bar thus held down engages a corresponding punch 85, and causes this punch to perforate a card held between reciprocable plates 86, 88. The operation of a key and consequent movement of a rod 92 also actuates a second lever 62, a finger 61 on which lifts a corresponding stop causing a rack number bar 16 to be lifted from engagement with a zero stop and shifted by a spring 21 to a position in accordance with the stop raised. The bar sets a type wheel 13 for printing on a web 11 of paper, and at the same time brings the corresponding number on a block 17 into line with a sight slot. The bar 16 is returned by a bell-crank frame 25 having a periodic motion. The amounts set up and printed by the rack 16 are accumulated by a rack 30 having a pin and slot connection with the rack 16, the racks moving together to make the accumulation and moving relatively to carry over from one wheel to the next. The rack 30 is under tension of a spring 23 and is capable of being held against this tension by a carry pin 40 on a pivoted member 41 having a pawl actuated by a cam 43 of the accumulator wheel of next lower order. The wheel is held against undesired rotation by a detent 47 on a rock arm 48, and its shaft is rocked periodically to bring the pinion in and out of mesh with the rack 30 as required for entering an item. The pawl member 41 is temporarily locked in carry position by a lever 53 snapped under a fixed latch bar 56 by a spring 55 when the pawl is shifted by its cam.
