Title: Process for the manufacture of cushion tyres having a hollow core
IPC: B29D30/06
Filed: 1926-12-29
Abstract: 265,929. Pirelli & Co. Feb. 19, 1926, [Convention date]. Vulcanizing - cores. - A A cushion tyre having a cavity at its base is made by culcanizing a tyre on an endless rim, the cavity being filled with a fabric or like bag containing a material in a state of division and capable of withstanding the heat of vulcanization, this material being subsequently removed through holes in the rim. In a central channel 6 of a rim 5 is placed a core 4 which may comprise a canvas bag filled with sand, the tyre 1 with base 11 of hard rubber is placed on the rim and core, and vulcanized in a mould 10. After vulcanization the sand is removed by an air or liquid blast through holes in the rim which are afterwards filled with metal plugs.
Patent GB-392961-A (GB)
Title: Improved means for auxiliary signalling in printing telegraph systems
IPC: H01H67/26
Filed: 1931-11-27
Abstract: 392,961. Type-printing telegraphy. CREED & CO., Ltd., Telegraph House, Croydon.-(Teletype Corporation ; 1400, Wrightwood Avenue, Chicago, U.S.A.) Nov. 27, 1931, No. 32918. [Class 40 (iii).] In a printing-telegraph system using a code having a starting element followed by a series of permutation elements of operative or non-operative character, a bell or other auxiliary signal is selected for operation on the receipt of a blank signal in which all the per-. mutation elements are of non-operative character. The bell &c. is actuated by the next code signal if of predetermined character, say that for effecting line feed, but by no other. In the system described, the permutation signals are distributed to five magnets 2, Figs. 1 and 2 (two only being shown), printing being effected by a magnet 21 (its armature 22 only being shown in Fig. 1), energized by a locally produced impulse. Arms 5 attached to the armatures 4 of magnets 2 co-operate with the notched ends of latches 9 connected by pin and slot to a common release bar 14 in such a way that when, during a normal signal, one or more magnets 2 are energized, the corresponding armatures are locked by the ends of the latches 9 and the bar 14 is moved to the right. A lug 33 on the bar 14 unlocks the armature 22 of the printing magnet 21 so that this is attracted in due course, engaging lug 31 to move the bar 14 to the left, thereby unlocking the armatures of the magnets 2 ready for the next code signal'. If, however, a blank signal is received, so that none of the magnets 2 is energized, the bar 14 is not moved to unlock the armature 22, so that the energization of magnet 21 at the end of the signal is without effect. A magnet 35, Fig. 3, in parallel with magnet 21 is, however, energized over contact 38, which is closed since the bar 14 has not been moved. The magnet 35 moves the member 47, Fig. 4, into the position shown in dotted lines, where it is held by a latch 56, the forked end 52 of the member 47 moving from beneath the member 61 to beneath the member 62. The members 61, 62 are both operated in response to the same code signal, say that for effecting line feed, but whereas the member 62 effects the line feed the member 61 only-controls the bell signal. If, therefore, the line feed signal is received immediately after the blank signal, i.e. when the magnet 35 has been energized and its armature is held in its attracted position by the latch 56, the member 62 is blocked by the forked end of the member 47 and the line feed mechanism is inoperative, but the member 61 is operated to ring the bell. If, however, the line feed signal is received at any other time, the member 47 blocks the member 61 to prevent actuation of the bell but frees member 62 to actuate the line feed. The latch 56 holding the member 47 is tripped by an arm 71 which rotates when the armature of the printing magnet 21 is attracted. The bell signal is thus only given when the blank signal is followed by, say, the line feed signal.

Title: Improvements relating to the production of charge pellets containing metal oxides
IPC: C22B1/242
Filed: 1961-09-19
Abstract: Charge pellets containing metallic oxide and carbonaceous reducing agent, for use in smelting metals, are produced by mixing the oxide with an hydraulic binder, e.g. Portland or alumina p  cement such as made from basic furnace slag, and a bituminous binder, such as crude baking coal preferably ground to powder so that at least 50% of the grains pass a 200 Tyler mesh and containing 1-3% pitch, forming the mixture into pellets with water, and allowing to harden without heating.  The cement may comprise 3-10% of the mixture.  The pellets may be subsequently preheated and prereduced at 500-1000 DEG  C., e.g. in one or more shaft furnaces or a rotary kiln, to coke the bituminous binder. The hot preheated pellets may then be transferred to an electric smelting furnace for final reduction.

Title: Machine for reading perforated cards

Abstract: 505,923. Statistical apparatus. KRELL, J. Dec. 6, 1937, No. 33681. Convention date, Dec. 11, 1936. [Class 106 (i)] In a machine for reading perforated cards and reproducing the data read on to an indicator side by side, an indicating or numeral wheel 16 for each card column to be read is driven frictionally and coacts with a peripheral row of stops 14 equal in number to the number of hole positions in a card column, the appropriate stop 14 being projected by mechanical or electromagnetic means from the hole read to arrest the corresponding indicating wheel 16 in correct indicating position. A card is placed by hand in slotted guides 3. For each card column there is a column of sensing pins 11 which coact with pins 7 on the ends of the cores of Bowden cables 13 ; the other ends of the cores carry the stops 14. Each wheel 16 has a lug 18 (normally in the position shown) and is driven by a friction pad 22 spring supported in an.arm 21 rigid on shaft 17. A wheel 24 on shaft 17 meshes with a sector 25 on a shaft 26 operated by a hand crank 27, or by pedal or electric motor. An arm 28 on shaft 26 engages a pin 29 on a sleeve 30 connected by spring 33 to one of the guide rods 10 of the pin box frame 8. When the handle 27 is depressed, pins 11 are moved towards and read the card to project the appropriate stops 14. At the same time the pads 22 rotate the wheels 16 until their lugs 18 meet the projected stops 14. The correct numerals on wheel 16 then show at window 20. For clarity of reading, the cable connections 13 permit the wheels 16 to be wider than the pitch of the card columns. If the card is read by electric contacts, a small electromagnet is associated with each stop 14. The guides 3 are adjustable by means of holes 12 in the supporting plate 2 so that cards of different size may be accommodated or so that selected columns of a card may be read.

Abstract: 735,846. Stuffing-box packing. ILLINOIS TOOL WORKS. Dec. 7, 1953, No. 34004/53. Class 122 (5). [Also in Groups XXVIII and XXXVI] An electrically insulating grommet for insertion in an aperture in wall 21 comprises a hollow rivet 12 and a sleeve 14, the rivet consisting of a shank 18, a head 16 for engaging one side of the wall and a transversely yieldable portion 20 for engaging the outer side of the wall, and the sleeve 14 projecting from the head 16 so that it can be telescoped into the rivet 12. The portion 20 may be in the form of yieldable fingers having curved end surfaces 22 to facilitate the insertion of the grommet into the aperture. The sleeve 14 is initially integrally joined to the rivet 12 by a thin connection and the outer extremity of the sleeve comprises a plurality of outwardly flared fingers 24. After threading a conductor, rod or tube through the grommet and mounting the rivet in the aperture, the sleeve is driven axially into the rivet (Fig. 6), breaking the thin connection. The fingers 24 are forced inwardly into light engagement with the conductor, rod or tube, and the fingers 20 and shank 18 are forced outwardly into tight engagement with the wall. The grommet may be longitudinally slotted to permit lateral insertion of the conductor, rod or tube, the slot in the sleeve 14 being displaced with respect to the slot in the rivet 12 so that in the final position the slots are not superimposed.
