Title: Pneumatic tires
IPC: B60C9/17
Filed: 1967-08-01
Abstract: A pneumatic tyre has a crossed cord reinforcement beneath the tread and in a part of each sidewall extending from a bead to substantially the mid-height of the tyre and a radial cord reinforcement in the other parts of the sidewalls, the radial cords being integral with oblique cords forming part of the crossed cord reinforcement of at least one of the sidewalls. A typical tyre of the above construction is shown in Fig. 1 wherein broken lines represent oblique cords and full lines radial cords. As shown, the reinforcement comprises two plies 2, 21 each extending from about the mid-height of the tyre around a bead wire 8, 81 to a point 4, 41 in the region of the edge of the tread. Cords in overlapping sections of the plies in the regions 2A, 21A, and beneath the tread 3 have opposite obliquities. In modifications, the reinforcement may comprise (a) a single carcass ply extending from about the mid-height of the tyre in one sidewall around the bead wires to the same position in the other sidewall and a crown reinforcing ply extending over the width of the tread located above the carcass ply, see Figs. 4-6 (not shown) (b) two superimposed carcass plies extending from beadwire to beadwire, a crown reinforcing ply located between the two carcass plies, and plies located between the two carcass plies in the region of the beadwires, see Figs. 7-9 (not shown) or (c) a single carcass ply extending from beadwire to beadwire, a crown reinforcing ply located above the carcass ply, and two plies located in the sidewalls and extending from a beadwire to about the midheight of the tyre, see Figs. 10-12 (not shown). Tyres of the above construction may be made by laying a ply of oblique carcass cords on a tyre building drum, laying plies of cords of obliquities differing from that of the carcass cords in the region of the crown and of each bead, and bringing the cylindrical structure to tyre shape, the obliquities being chosen so that the expansion resulting from shaping leads to the reinforcement arrangements indicated above. One or more of the plies laid on the carcass ply may be integral parts of the carcass ply.

IPC: C08F255/02
Filed: 1968-04-03
Abstract: A product containing from 1 to 35% by weight of a vinyl acetate/ethylene copolymer is obtained by thermoreticulating a vinyl acetate/ethylene copolymer bulk grafted with vinyl chloride.

Title: Process for Alkylating Aromatic Hydrocarbons
IPC: B01J27/16
Filed: 1968-05-03
Abstract: A process for monoalkylating aromatic hydrocarbons by reaction with an olefin in the presence of a solid particulate alkylation catalyst comprises introducing all of the aromatic and olefinic reactants and an unreactive vaporous dispersant into the lower portion of a reaction zone and passing them upwardly in mixed phase through at least one fixed bed of catalyst, withdrawing from the upper portion of the reaction zone the resulting reaction mixture comprising monoalkylated aromatic hydrocarbon, excess unreacted aromatic hydrocarbon and vaporous dispersant, and recovering the monoalkylated aromatic hydrocarbon.

Patent ES-369087-A1 (ES)
Title: Two disc induction meter
IPC: G01R11/36
Filed: 1969-07-03
Abstract: An induction motor meter for a four wire, three phase supply incorporates two rotor discs 1, 2 solid with and spaced along a common shaft 3, there being respective pairs of stator windings for each phase, two of the pairs co-operating with the disc 2 and the third pair co-operating with the disc 1. Each pair comprises a first, (current) winding, 42, 52, 62 respectively in the space between the disc and a second (voltage), winding 41, 51, 61 respectively on the opposite side of the respective disc outside the space. The magnetic circuit of the first winding of the third pair partially overlaps the magnetic circuits of the first windings of the other two in a longitudinal direction parallel to the shaft, to reduce the spacing between the discs. The planes of the first two pairs of windings are slightly inclined to the disc diameters parallel to the place of the third pair and the centres are slightly displaced to the plane of this diameter, to compensate for error due to change in the order of phase succession. The arrangement is such as to reduce stray coupling between the different electromagnetic circuits.

Title: Methods of and apparatus for twisting and stranding cable pairs in a tandem operation
IPC: D07B3/00
Filed: 1972-06-28
Abstract: A twist is imparted in each pair of a plurality of pairs of insulated conductors for each revolution of an associated flier bow as each of the pairs pass over sheaves at opposite ends of the bow in a high speed twister. Each of the twisted pairs is passed from the twister along a predetermined path through an associated untwist-retwist device in which the twisted pair is untwisted by advancing successive sections of the individual conductors along separate paths and revolving the successive sections of the conductors being advanced along the separate paths about the predetermined path. Subsequent to the successive sections of the individual conductors of each of the untwisted pairs being moved away from the associated untwist-retwist device, a double twist is imparted to each pair in a uniform distribution. The plurality of retwisted pairs are moved immediately into a strander to form a cable having a binding applied thereto to thereby retain the uniform distribution of twist.

Title: Diagnostic system for heat pump
IPC: G01R31/00
Filed: 1978-10-02
Abstract: A diagnostic system is provided for apparatus including a heat pump, a thermostat and a logic module intercoupled to regulate operation of the heat pump electro-mechanical units. The normal control and operating circuits for the heat pump are completed over a wiring harness plugged into an electrical connector on the logic module, which also receives a plurality of sensor information inputs. To check the system, the diagnostic system has a first cable terminating in an interconnector, inserted between the electrical connector on the module and the harness plug. The sensor inputs are disconnected, and additional connectors, carried in a second cable of the diagnostic system, are coupled to the sensor input connections on the logic module. When thus connected, the diagnostic system monitors operation of the thermostat, even though the module is removed at a considerable distance from the thermostat, and also actuates the heat pump units to check their operation. An ohmmeter is included in the diagnostic system, to measure the resistance of the various sensors, and provide an indication of the temperature at a given sensor location. With this diagnostic system, the thermostat, logic module and heat pump units are all rapidly checked from a single location.
