Abstract: 1. An arrangement for monitoring digital radio links comprising two end stations and at least one intermediate station (Z), arranged between these end stations, with a receiving section and a transmitting section, by means of additional bits whose arrangement is defined by a super-frame, and where, when the failure of a connection is established in an intermediate station, the super-frame is re-formed, all the information bits are set at the logic value 1 and the information bits are scrambled, and the failure of the connection is reported to the following intermediate stations by means of a service bit in the re-formed super-frame, characterised in that in the base-band preparation unit (BSZ) of the transmitting section of the intermediate station, which in the event of a fault assumes the function of a new end station, in the signal path between an input-end interface assembly (INT) and an output-end difference coder (COD) are interposed a multiplexer (MUX) for super-frame formation and a scrambler (SCR) which are connected to a clock central control (TZ) for the generation of a control clock signal for the super-frame formation, that the clock central control (TZ) is connected to a clock oscillator (OSZ) and the interface assembly (INT) and also to the coder (COD), that multiplexer (MUX) and scrambler (SCR) and clock central (TZ) possess a control input (S1M, S1T) for a control signal which occurs in the event of a failure, that an elastic store (ES) is interposed between the interface assembly (INT) and the multiplexer (MUX), which store controls a voltage-controlled oscillator (VCO) connected to the clock central control (TZ), and that multiplexer (MUX) and scrambler (SCR), clock central control (T2) and interface assembly (INT) possess a further control input (S2M, S2T, S2I) via which a further control signal switches over the arrangement from the intermediate station operation to end station operation.

Abstract: A one-piece plastics closure for a carbonated beverage bottle has a sealing ring (17) pivotally attached at the junction between its closure panel (10) and dependent skirt (11). The sealing ring is forked, having two annular and mutually divergent fins 20, 21. The upper fin (20) is engaged by the free end of the container neck as the closure is fitted, and by pivotal movement of the sealing ring brings the lower fin (21) into sealing relation with the side surface of the container finish. The resilience of the closure material and the substantial deformation to which the sealing ring is subject thereafter maintain the effectiveness of the seal despite creep and backing-off of the closure which may occur.

Abstract: In producing hollow bodies by blow molding from thermoplastic material, a preferably tubular preform is firstly formed, and is then expanded within the blowing mold under the effect of an inert gas under high pressure, until it bears entirely against the inside surface of the blowing mold. Thereafter, a reaction gas such as fluorine is introduced into the hollow body under a considerably lower pressure, while the hollow body is still in the mold, to treat the internal surface of the hollow body to render it impervious to gas and/or liquid. After the reaction has elapsed, a flushing and cooling gas is introduced into the hollow body and is then removed from the blowing mold after the hollow body has sufficiently set.

Each leg bar (14,15) is attached at one end to a thigh band (16,17) which is free to rotate about an axis which is perpendicular to the leg bar (14, 15). The other end of each leg bar (14,15) is rotatably held in a pivot (12, 13) attached to the waist band (11). Each pivot (12,13) is capable of being inclined downwards with respect to the plane of the waist band (11). The spacial relationship of the axis of the pivot (12, 13) and the distal end of the leg bar (14, 15) is such that the device operates by maintaining the legs of the wearer in abduction that is appropriate to the extent of hip flexion by altering the separation of the legs in a smooth and controlled way during hip flexion.

Abstract: The present invention relates to a method and apparatus for keeping a screen surface or a filter surface clear. The method and apparatus according to the invention is especially suitable in connection with thickeners, screens and filters intended for treating the fiber suspensions in the pulp and paper industry. The greatest disadvantage of all above-mentioned equipment is the tendency of perforated screen/filter surfaces to become gradually clogged as fibers of pulp suspensions adhere to the openings in the screen/filter surface. In the method of the invention, pressure fluid is introduced from a conduit (5) to the secondary side (10) of the screen/filter drum (6), which fluid flows, during the underpressurized stage caused by the blades (9) of the rotor (7) rotating on the primary side of the screen/filter drum (6), through the screen/filter drum (6) from the secondary side to the primary side thereby rinsing the openings of the drum (6) and making them clear.

Abstract: The invention relates to a cross-lapper (1) with at least two rotating conveyor bands (6, 7) and at least two carriages (4, 5) moved in a reversing manner and accelerated at the reversal points of their travel. To influence the pile thickness in a controlled manner, the band running speed and the travelling speed of the carriages are uncoupled from one another between the acceleration phases and are set differently in relation to one another. For this, there are separate drives (14, 15), especially servo-drives, at least one of which has a freely programmable control (15, 13). In the travel zones between the reversal points of the carriages (4, 5), a constant or variable speed difference in relation to the conveyor bands (6, 7) is produced, this being expressed in a change in the deposited pile thickness (9). When the carriages (4, 5) move faster, the pile becomes thicker, and with the opposite speed difference the pile thickness becomes smaller.
