Abstract: Un dispositif d'affichage électrophoretique comprend des conducteurs de grille (10) et de cathode (4) disposés sous forme d'une matrice X-Y espacée d'une anode (14), avec une dispersion électrophorétique entre les deux. Des particules de pigment dans la dispersion sont chargées au niveau de zones d'intersection choisies de la matrice X-Y, et migrent vers l'anode (14) pour y produire une image d'affichage lorsque la cathode (4) est négativement polarisée par rapport à l'anode (14), l'image étant effacée lorsque la cathode (4) et l'anode (14) sont polarisées de façon opposée. L'anode (14) est constituée d'une multiplicité de segments (62) de lignes d'anode parallèles correspondant aux lignes d'image de l'affichage, et un circuit de commande est prévu pour commander individuellement le potentiel appliqué à chaque segment (62) de ligne d'anode afin de permettre l'effacement sélectif d'une ou de plusieurs lignes et la réinscription de ces lignes uniquement. Un nouveau bloc d'image dont une partie importante est identique à un bloc précédent peut ainsi être plus rapidement réinscrit.

Abstract: Dans les appareils de traitement photographique connus, on utilise des pompes pour assurer la recirculation et le recyclage des solutions de traitement afin d'obtenir l'agitation nécessaire des solutions de traitement. De telles pompes, cependant, sont normalement montées sur l'extérieur du réservoir de traitement et lui sont reliées par un système de tuyauteries souples. Cette invention décrit un agencement de réservoirs de traitement modulaire (10, 14, 16, 18) dans lequel les pompes (38, 40, 42) sont montées solidaires avec le module. De ce fait, le module tout entier peut être déposé sans qu'il soit nécessaire de déconnecter un grand nombre de tuyaux.

Abstract: An optical beam scanning apparatus of a high resolution, compensates the increase and change of the diameter of a scanning beam, uneven rotation of a hologram rotating body, the positional changes in the directions of main and subscannings by the mode hopping of the wavelength of a semi-conductor laser, and the deterioration of the parallelism of the base of the hologram rotating body, etc., which mar the resolution and impede the cost reduction of a hologram scanner. The apparatus uses only the holograms that are duplicated in large quantities, without using auxiliary optical systems such as optical lenses and mirrors with curvatures. On a rotating body (1) and a fixed plate (2), provided are respectively diffraction gratings (1a, 2a) which minimize the sum of the weighted values of the squared or absolute values of the differences of two light path lengths, the weighting being conducted for each of scanning points on the entire image-forming surface (4). One of the two optical path length is of a light beam on the principal axis (MA), which is diffracted by the diffraction grating (1a) and by the diffraction grating (2a) and then, is focused at a scanning point (k) on the image-forming surface (4); the other is of a light beam on a peripheral axis (MI) different from the principal axis (MA). Alternatively, the diffraction gratings (1a, 2a) minimize the sum of the weighted values of the squared or absolute value of the sum of two phase differences, the weighting being conducted for each of scanning points on the entire image-forming surface (4). One of the two phase differences is the shift of the phase of the diffraction grating (1a) on the rotating body (1) from the principle axis (MA) when the light beam is focused at the scanning point (k); the other is the shift of the phase recorded on the diffraction grating (2a) from the principle axis (MA) when the light beam strikes the stationary plate (2).

Abstract: Collagen-like polymers having repetitive triads are produced having reduced proline content, where glycine is the initial amino acid and the subsequent amino acids are varied, while retaining at least a minimum percentage of prolines. The resulting polymers have collagen-like properties, but are capable of being produced in unicellular microorganisms at high molecular weights and in high efficiency. The polymers while retaining collagen-like characteristics, include various novel sequences which impart new characteristics, finding wide use in photographic, medical, structural and fiber applications.

Abstract: A tiny electret assembly for an electroacoustic hearing aid transducer, either a microphone or a sound reproducer, includes a thin, flexible, planar diaphragm (21) and a planar backplate (22), the diaphragm and the backplate constituting the electret electrodes. One of the two electrodes is permanently charged to a given differential voltage relative to the other and the two electrodes are mounted, in the transducer, in fixed, spaced, substantially parallel relation to each other; the differential voltage between the electrodes pulls a central portion of the diaphragm toward the backplate (22), tensioning and stiffening the diaphragm (21). The mount (23,24) for the diaphragm (21) permits movement of the diaphragm rim in the plane of the diaphragm but precludes movement of the rim of the diaphragm perpendicular to the plane of the diaphragm (and the backplate) so that the diaphragm cannot buckle. Different rim mounts for the diaphragm are described.

Abstract: A method of making a spacer frame assembly including the steps of providing a supply of thin, flexible relatively narrow sheet metal ribbon stock, feeding the ribbon stock endwise to a first forming station (104), stamping the ribbon stock to form spacer frame corner structures at the first forming station by defining zones of weakness at frame corner locations spaced along the stock, stopping the movement of stock through the first forming station while stamping, feeding the stock to a second forming station, and roll forming the stock at the second forming station (110) to define a rigid linearly extending frame element having opposite side walls and a base wall, the corner structures disposed at least in part in the opposite channel side walls. The method further includes the steps of severing the frame element to define leading and trailing spacer frame element ends, accumulating stock between the first and second forming stations comprising forming a variable length stock travel path segment, maintaining a substantially continuous movement of the stock through the second forming station, and increasing length of the stock travel path segment when the stock speed through the first forming station is greater than the feeding speed through the second forming station and reducing the length of the stock travel path segment when the feeding speed through the second forming station is greater than the feeding speed through the first station.
