Abstract: A carrier particle for electrostatographic developer mixtures, having a core and an outer coating. The core is of an average diameter between 30 microns and 1000 microns. The outer coating comprises a polyvinyl acetal such as polyvinyl butyral or polyvinyl formal. The coated carrier particles have negative triboelectric charging properties and are particularly useful in development systems, employing negatively charged photoconductive surfaces. Imaging processes are also disclosed.

Abstract: Nickel alloys for single crystal casting have been produced by varying the proportions of the constituents of a commercial alloy originally developed to give equiaxed polycrystalline castings and optimum compositions suitable for the production of single crystal castings have been obtained. The new alloys have compositions within the range (in weight per cent):
     Individual alloys have been shown to have enhanced creep rupture strength and high impact resistance compared with commercial alloys where the latter are cast as single crystals.

Abstract: In apparatus for reproducing video signals recorded in successive parallel tracks (T) extending obliquely on a record tape (1), which apparatus includes a rotary head (4) repeatedly scanning across the tape generally in a direction along the tracks for reproducing the signals recorded therein while the tape is advanced, as by a capstan (7), longitudinally at a selected reproducing speed which is any arbitrary ratio n of a normal reproducing speed (corresponding to the recording speed), and a transducer deflecting device, such as a bi-morph leaf (5), responsive to a drive voltage for deflecting the head in a direction transverse to the direction along the tracks; a tracking control system is provided with a circuit (22, 24, 26-29) for determining the value of said ratio n, for example, by detecting corresponding variations (AH) in the horizontal period of the reproduced signal. A ROM (30) is responsive to the digital signal (Dn') corresponding to value n for extracting, from said value of the ratio n, the values m and / of an integer and a fraction, respectively, which aggregate the ratio n. A jump voltage forming circuit (37) is provided for forming relatively large and small head jump voltages which respectively correspond to said value m and a value (m - 1). A reproduced phase (r) of the output of the head (4) is provided in correspondence to a specific position (the center) along a track, and a reference phase (q) is provided on the basis of said value /. A D-type flip-flop (48) acts as a discriminator for determining whether the reference phase (q) is in leading or lagging relation to said reproduced phase (r), and selector (39) is responsive to the output (i) of the discriminator for selecting one of said large and small head jump voltages (m) or (m - 1). At the end of each scanning of a track, the then selected one of said large and small head jump-voltages (m) or (m - 1) is included by a driving circuit in the drive voltage applied to bi-morph leaf (5) for determining the next one of the tracks to be scanned.

Abstract: Piton dont la force de resistance a l'extraction est accrue. La plupart des pitons conventionnels sont pourvus de moyens pour en prevenir l'extraction tels qu'une rainure en spirale ou des rainures annulaires formees a l'extremite de la tige. Lorsque le materiau de base dans lequel le piton conventionnel est enfonce est un materiau poreux mou tel que du beton-mousse, les moyens d'empechement d'extraction de ces pitons conventionnels n'offrent pas une force suffisante d'empechement d'extraction et l'effet de retention obtenu est insuffisant. Ce piton comprend une paire de tiges (1, 1) opposees l'une a l'autre longitudinalement avec une plaque metallique en forme de bande (2) disposee entre elles, les extremites des tiges (1, 1) etant formees avec des surfaces effilees (5) vers l'interieur. Ainsi, lorsque le piton est enfonce dans un materiau de base (9), les tiges (1, 1) divergent progressivement dans le materiau de base (9), tandis que la plaque metallique (2) est comprimee et deformee suivant une forme en zig-zag de maniere a preserver l'action d'expansion des tiges (1, 1) a partir de l'interieur et pour engager les tiges (1, 1) dans le materiau de base (9), empechant ainsi l'extraction du piton et accroissant la force d'empechement d'extraction de celui-ci. En outre, le piton comprend aussi une bague de serrage (7) disposee autour des deux tiges (1, 1) et de la plaque metallique (2), empechant ainsi les tiges (1, 1) de s'etendre sur la surface du materiau de base (9) et aidant les tiges (1, 1) a penetrer profondement dans le materiau de base (9) tout en empechant le trou du piton a la surface du materiau de base (9) de s'agrandir.

Abstract: A domestic tumble dryer is provided with a series of temperature sensors exposed to exhaust air leaving the drum of the dryer, heated air entering the drum, ambient air and air entering the heater. These sensors input to a microprocessor (1) via a suitable interface (2). Also inputting to the microprocessor via the interface (2) is a user operable selector (4, 5, 6) that indicates to the microprocessor the material of articles to be dried in the dryer. The microprocessor is programmed to monitor the sensor inputs during at least the initial part of a drying cycle and to derive exhaust air temperatures that are compared with those of drying cycles stored in the microprocessor. As a result of the comparison the microprocessor deduces the time required to effect drying to a degree of dryness required by a user and to terminate the drying cycle. An indication, corrected from time to time whilst the microprocessor is monitoring exhaust air temperature, of the cycle duration time is also displayed.

Abstract: A television ghost signal cancellation system is provided in which the video intermediate frequency signal is demodulated by two synchronous detectors (10;20). A picture carrier extractor (12) produces a first reference signal for the first of the synchronous detectors, exhibiting a phase which is aligned with that of the picture carrier of the direct television signal. The first reference signal is shifted in phase by a controllable phase shifter (14) to develop a second reference signal for the second synchronous detector. The output of the second synchronous detector (20) is delayed by an amount of time equal to the difference in time between the appearance of the direct signal and a detected ghost signal. The amplitude and polarity of the delayed signal are adjusted by a control circuit (40) to produce a pseudo-ghost signal. An amplitude comparator (42) compares the amplitude of the pseudo-ghost signal with that of the output signal of the first synchronous detector. The resultant amplitude comparison signal is sampled and stored (44) and the stored signal is used to control the adjustment provided by the amplitude and polarity control circuit. A phase comparator (16), responsive to the outputs of the amplitude and polarity control circuit and the first synchronous detector for producing a phase comparison signal, provides a phase comparison signal which is sampled and stored 118), with this stored signal used to control the phase shift provided by the controllable phase shifter. The pseudo-ghost signal and the output of the first synchronous detector are summed (50) to produce a deghosted video signal.

Abstract: The gasification takes place under pressure in a gasification chamber (3) at a level (III) which has been lowered with respect to the final level (II). Disposed in the chamber are mechanical energy input devices (4) for improving the mass transfer coefficient (KL.a); said devices (4) transfer the gas to be introduced from a pressurised gas cushion (8) to the liquid (9). The lowering of the level (III) renders a supply of energy to produce the required overpressure unnecessary; the mechanical energy input in the gasification makes possible an optimum utilisation of this energy and a simple and effective control and matching of the mass transfer coefficient (KL.a) to varying throughputs (Q). <IMAGE>
