Abstract: In a digital radio transmission in which first- and second-channel radio frequency digital signals are transmitted respectively on orthogonally polarized radiowaves and first and second IF signals are derived respectively from the first- and second-channel RF signals. The second IF signal is proportioned in response to a control signal and subtractively combined with the first IF signal. A main digital demodulator (40-1, 40-2) provides demodulation on the combined IF signals to generate a main (N+1)-bit output and derives an N-bit data signal from N higher significant bits of the (N+1)-bit output and an error component from the LSB of the main (N+1)-bit output. An auxiliary digital demodulator (80-1, 80-2) provides demodulation on the second IF signal to generate an auxiliary (N+1)-bit output and derives a data component of the second channel from the MSB of the auxiliary (N+1)-bit output. The derived error and data components are supplied to a correlator (50-1; 50-2) to generate the control signal.

Abstract: Porous acrylic and modacrylic fibre having a porosity above 0.3 cm³g⁻¹, an internal surface area of at least 50 m²g⁻¹ (when its decitex is greater than 2.5) or at least 35 m²g⁻¹ (when its decitex is not more than 2.5), and a water imbibition of at least 65% (when its decitex is greater than 2.5) or at least 55% (when its decitex is not more than 2.5) and other porous acrylic and modacrylic fibre can be produced by contacting never-dried, standard wet-spun fibre with a water-miscible organic liquid which is a non-­solvent for the fibre and has a boiling point below the glass transition temperature of the fibre to exchange the water in the fibre for the organic liquid, and then drying the fibre so as to remove the organic liquid without collapsing the fibre. Porous fibre made in this way or other porous acrylic or modacrylic fibre in dry or never-­dried state can be impregnated with an additive either by immersion in a solution of the additive in an organic liquid of the above type or by immersion in a solution or liquid dispersion of the additive in a different liquid followed by exchange of that liquid with an organic liquid of the above type, followed in either case by drying to remove the liquid. The drying conditions can be controlled to provide uncollapsed fibres, fully collapsed fibres or, preferably, novel partially collapsed fibres, from which the additive is released in a sustained fashion at a rate determined by the degree of collapse of the fibres.

Abstract: Recording and/or reproducing apparatuses with magnetic tape storage have the disadvantage that, due to running over and over again and inadequacies in the tape guidance, step forming occurs in tape winding. This may result in damage to the tape and/or overloading of the motor. To avoid excessive step forming in tape winding, the new circuit has a counting device, which counts the number of tape movement sequences immediately following one after the other and returning to the original tape position. When a predetermined number of such movement sequences is reached, the entire tape is first of all rewound in the forward direction and then in the backward direction and, after the rewinding operation, the tape is wound back again to the original starting position. The rewinding operation can also be triggered by a motor current indicator and a threshold switch connected to the latter or by a control voltage which can be picked up from a control device of the motor or by the evaluation of signals at the output of tape- positioning pulse generators in a microprocessor. <IMAGE>

Abstract: A synthetic resin composition having particles of metallic gallium or gallium alloy dispersed uniformly in a synthetic resin is particularly useful for the production of a surfacing material for a glider on snow or ice. This is because when a molten paraffin wax is applied to such surfacing material, part of the wax penetrates into the sheet to form a gallium-paraffin mixture on the surface of gallium particles and at lower snow or ice temperatures, the gallium particles expand, and as the result of their expansion, gallium particles are held strongly enough on the gliding surface of ski to maintain good water-repelling and glide characteristics over a prolonged period without allowing the gallium-paraffin mixture to come off the ski. 
     The composition is also useful for many other similar uses such as a plastic gear, a constructional material, a marine structural material and the like because of its excellent glide, water-repelling and wear resisting properties, which can be retained for a prolonged period.

Abstract: An apparatus is disclosed for controlling fluid flow at a flow control location between first and second rollers (12, 16). Each roller is rotatable about its longitudinal central axis. The two rollers (12, 16) are disposed adjacent to each other so as to form a flow control location or nip (18) between the rollers. The nip (18) has an entrance side (11) and an exit side (13). As the rollers (12, 16) rotate, fluid from a fluid pan (14) is carried on the outer surface of the first roller (12) to the entrance side (11) of the nip (18). Some of the fluid at the nip (18) is transferred onto the outer surface of the second roller (16). As the rollers (12, 16) continue to rotate, the fluid flows out of the nip at the exit side (13) of the nip (18). An excess fluid condition occurs at the nip (18) when the amount of fluid flow to the entrance side (11) of the nip (18) exceeds the amount of fluid flow from the exit side (17) of the nip (18). A brass collar (30) is connected at one end of the first roller (12). Another brass collar (35) is connected at the other end of the first roller (12). The two brass collars (30, 35) rotate with the first roller (12) and cooperate to prevent excess fluid at the entrance side (11) of the nip (18) from flowing around the opposite axial ends of the nip (18) onto the second roller (16). This is accomplished by the two brass collars (30, 35) picking up excess fluid at the entrance side (11) of the nip (18) and subsequently transferring the excess fluid back to the fluid pan (14).
