Abstract: 1497098 Stranding armoured cables CAMESA SA 8 Oct 1975 [2 June 1975] 41287/75 Heading D1T Armour wires that are to be stranded about a core are heated prior to their arrival at the stranding station, the heated wires being stranded around the core and then cooled to cause them to be a shrink fit on the core. In Fig. 1 a core 13 is fed through a first rotating assembly 18 containing a plurality of supply spools. The wires 17 from the supply spools are heated by means 27 before passing through a preforming head 15 and the stranding die 16. In Fig. 1 the resulting cable 19 passes through a further and similar stranding assembly 24, 21, 22 in which the wires 23 are heated before being stranded around the cable 19. The core 13 may itself be a wire or a family of wires, a hydraulic hose or one or more electrically insulated conductors or the like. The stranding elements 17 may be metallic wires, plastic fibers, or the like, and may have round, square or other shaped cross-sections. The stranding wires may be heated to between 90C and 200C say. Heating may be by flame burners or by passing current through the wires.

Abstract: 1,082,484. Data transmission. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEURGENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Oct. 13, 1964 [Oct. 15, 1963], No.41726/64. Heading H4P. A digital data transmission system in which errors are corrected by repetition comprises first and second stations, each of which transmits a sequence of data signals to the other. In both sequences, adjacent signals belong to alternate groups. Each station must receive an unmutilated signal from the other station prior to transmitting a signal in the sequence. If a station detects an error, then, instead of the next signal in the sequence, it transmits a service signal indicating the group of the character awaited (i.e. of the character mutilated) and the group of the character that the station intends to transmit next. On detection of this service signal the required signal is retransmitted. If there is received a service signal indicating the intention to send a signal of a group which, is not that awaited by the receiving station, that station sends a service signal indicating the signal group which is required.

Abstract: 1,155,885. Treating tyres. H. TIES. 28 Sept., 1966 [30 Sept., 1965], No. 43450/66. Heading B3D. In a machine for preparing a worn pneumatic tyre 2 for retreading in which the tyre is clamped between two rim plates 4, 5 rotatable about a horizontal axis and driven by a knurled drive roll 8 engaging the circumference of the tyre, two rotary brushes 40 for removing projecting marks on the side walls of the tyre are journalled on means connected to a support 9 for the roll 8 for reciprocating movement in a direction radially of the tyre. The brushes 40 are journalled in arms 43 connected to links 41 pivoted to bearing housings 9d connected to the support 9. The roll 8 is urged against the tyre by means of a pneumatically-operated piston 9b movable in a cylinder 9c connected to the machine frame 1, the piston carrying a cylinder 52 in which a piston 53 is slidably guided and raised and lowered by feeding pneumatic pressure fluid through a hollow piston-rod 54 into the cylinder 52. The piston-rod 54 carries a yoke 55 from which two electric motors 50 are pivotally suspended, the movement of the piston 53 being transferred by means of two shafts 49 to the brushes 40. The upward movement of the brushes is limited by the abutment of the piston 53 with the upper wall of the cylinder 52 and the downward movement of the brushes is limited by an electrical contact 56 carried by the bearing of one of the brushes, engaging the should 5c of the rim plate 5. The brushes are brought into contact with the side walls of the tyre by means of pneumatic cylinders 51 connected to the links 41 and the piston-rods of which are connected to the arms 43.

IPC: B23B51/04
Filed: 1976-10-22
Abstract: Pocket-like recesses (4, 5) into which indexable inserts (6) are inserted are formed on the root of two opposite chip grooves (3). The indexable inserts (6) are of rhombic configuration with four main cutting edges (7). On account of the rhombic configuration, the main cutting edges (7) enclose angles other than 90 DEG  with one another.   One indexable insert (6) is arranged so as to project with its main cutting edge (7) beyond the drill axis (12) and to intersect the drill axis so that the material is also cut in the centre and no peg of material is left behind. In order to permit better chip disposal, the indexable inserts (6) have ground-in or sintered-in chip breaker grooves (15) adjoining the main cutting edges. These indexable inserts (6) are designed as through-hole inserts and are releasably fastened to the drill body (1) by means of a screw (10).

A handcuff comprises a body 21 and an arm 24 pivotally connected to the body to form a wrist-engaging loop, a pawl 28 movable in the body to engage the arm, and a pin tumbler cylinder lock for controlling movement of the pawl, the lock comprising a plug 37 interengaged with the pawl and rotatable without the aid of a key from a position therein it holds the pawl out of engagement with the arm 24 to a second position wherein it holds the pawl in engagement with the arm, the plug also being rotatable between the second and first positions and key releasable pin tumbler means 55, 56, 57 for retaining the plug in the second position. As shown, the lock plug 37 includes a pin 39 by which rotation of the plug raises the pawl 28 against spring loading 31. The plug 37 is provided with a key way 51 and the tumbler pins 55, 56 and 57 are arranged to be aligned (in one position of the plug) with cavities 58, 59 and 60 in the body 21, the cavities housing follower spring-loaded pins 61, 62 and 63. A further cavity housing a spring-loaded tumbler pin 71 is provided in the body 21 between the cavities 58 and 59 but diametrically opposite thereto, and a further cavity 74 housing a spring-loaded pin 75 is provided in alignment with the cavity 60. The plug 37 is provided with a cavity 78 at right angles to the axis of the cavity 70, whereby when the plug is in a "lock handcuff" condition. the pin 71 engages the cavity 78 and the pins 61. 62, 63 engage the cavities 52, 53, 54. If now the appropriate key is inserted in the plug the serrated edge of the key depresses the pins 61. 62. 63 and the back edge of the key depresses the pin 71 allowing the plug to be rotated through 180 degrees to a "release handcuff" condition wherein the pawl 28 is disengaged from the ratchet 27. The key can now be withdrawn. Two slots 80. 81 in the plug 37 co-operate with the pin 61 whereby the plug 37, may be turned bodily by means of a portion 38 through 90 degrees in the anticlockwise direction only, Fig. 4, from the "release handcuff" condition to an "applied handcuff" condition in which the arm 24 can be engaged with the pawl 28, after which the plug can be turned through a further 90 degrees to the "lock handcuff" condition from which the pawl can only be released by the key. A check pin 83 fixed in the body 21 co-operates with a groove 82 in the arm 24 to resist forcible release of the arm. A swivel 44 is provided on the body 21 and is retained by a groove and pin connection 48, 49. Suitable markings are provided on the body to identify the "lock" and "applied" conditions of the handcuff.
