Abstract: The invention relates to a nail-driving tool having a magazine (11) for nails (10) combined to form nail strips (5), and having a nail- transporting device, the nail strips (5) being pushed in the direction of a fixed stop face (2) by means of a spring element (8), it being possible for the nail strip (5) lying against the stop face (2) to be conveyed in the direction of the driving-out channel of the tool mouthpiece by means of a transporting element (3) connected to a conveying cylinder (6). In order to be able to handle nail strips (5) in which the nail shanks are arranged not with a gap but shank against shank, the nail-transporting device is provided with a transporting shuttle (1) which is guided so as to able to travel with the piston rod (7) of the conveying cylinder (6) in the longitudinal direction of the magazine (11), and which has a wedge-shaped nail-strip separating member (12) which becomes operative during the backward movement, and the transporting element (3) is designed as a feed clamp which engages laterally on the separated nail strip (5) during forward movement of the transporting shuttle (1), so that the nail strip (5) lying against the stop face (2) can be clamped between the transporting shuttle (1) and the feed clamp (3) and can be moved forwards by the transporting shuttle (1).

Abstract: A process and apparatus is provided for explosively forming plastic objects from shredded plastic such as recycled plastic having different compositions. The shredded plastic and an explosive gas mixture is introduced into a mold cavity having the shape of the object to be formed, and the gas mixture is ignited, generating sufficient heat and pressure to force the plastic to conform to the shape of the mold cavity. The temperature and pressure in the mold cavity is controlled during the explosion by releasing combustion gases from the mold cavity.

Abstract: The invention discloses a general technique of taking advantage of the stability of the modulator transfer characteristic in order to correct for second and third order distortion. These objectives are achieved in a way compatible with the nature of the video distribution frequency formats. The method of this invention for linearizing the amplitude transfer characteristic of integrated optic devices for analog transmission is accomplished by injecting pilot signals, monitoring the harmonic and intermodulation distortion content of the optical output, and feeding back bias signals to parametrically tune the operating points of the integrated optic modulator and of a predistortion network. General principles for realizing suitable parametrically tunable predistortion networks are also presented.

Abstract: The frequency of a clock for a receiving terminal is controlled based on a predetermined clock frequency of a terminal that produces a continuous stream of data at a predetermined frequency for transmission to the receiving terminal over a communications network of the kind in which data is transmitted between the terminals in discrete packets that are delayed on the network by possibly different amounts. Arrivals of packets that are sent to the receiving terminal are detected, time intervals between the arrivals of successive packets are determined, and the time intervals are processed to generate an estimate that is related to the predetermined frequency. The frequency of the receiving terminal clock is controlled in response to the estimate.

This system comprises a multi-frequency microwave frequency head, installed in an external unit, whose inputs are connected to the satellite antennas. Wide band demodulation is made possible by a microwave frequency source controlled by a synthesizer. Digital signals transmitted by a link cable ensure programming of the synthesizer and therefore of the selected TV channels. A remodulation in amplitude modulation is performed for supplying signals in the 40-860 MHz band, carried by an existing link cable for terrestrial antennas. The system finds particular application to the simultaneous reception of several TV channels.

Abstract: A binding system, employing a first plastic elongated strip with spaced integral studs and a second plastic elongated strip having similarly spaced apertures and recesses, is provided which resists impact forces caused by dropping a bound book. A first fixed spacing of studs is provided along a mid-span portion of the first strip and a second fixed smaller spacing of studs provided at both end portions of the first strip which reinforces the end portions against stud breakage or extrusion caused by impact forces. In the preferred embodiment, the three end studs at each end of the strip are spaced at a second fixed spacing distance stud center-to-center of only one-half the first fixed spacing at the long mid-span portion of the strip. In another embodiment, a generally second fixed spacing of one-third the mid-span spacing with the at least two of the end portion studs being staggered from the center longitudinal axis of the strip is shown. An additional embodiment includes one or more integral studs of the end portions of the strip having a substantially greater cross-sectional area than the studs in the mid-span portion of the strip. In each embodiment, the binding is end reinforced against impact forces.

Abstract: A disposable CO2 absorber for applictions in rebreathing systems uses a flexible bag-like pouch (4) to contain CO2 absorbent granules (5). The pouch includes an intake port (2) having a one-way valve (3) at the top of the pounch (4) and an outlet or exhaust port including a perforated cylindrical tube (6) in the bottom of the pouch (4). Exhaled gas containing CO2 passes through the one-way valve (3) at the intake port and contacts the absorbent granules (5) where a chemical reaction bonds the CO2 with the granules. The residual gas, substantially free of CO2, passes out of the pouch (4) through the exhaust ports (6) for rebreathing by the user. The flexure of the pouch (4) increases the efficiency with which the CO2 is absorbed. <IMAGE>

Abstract: The present invention relates to semipermeable mosaic polymer membranes of asymmetric structure and with a macroscopic distribution of the mosaic-forming anionic and cationic charges (sites). The membranes can be prepared by casting a polymer solution of an optionally charged matrix-forming polymer and at least one precursor polymer, incompatible with the matrix-forming polymer, in a selected solvent, into a film, forming a skin on one side of the film, precipitating the skinned film to form the asymmetric membrane and charging it by chemical reactions to introduce or complete their mosaic structure. These membranes have good permeability for electrolytes, such as salts of mono- or polyvalent inorganic acids, while retaining low molecular weight organic solutes.

Abstract: L'invention concerne des améliorations apportées à un procédé permettant d'obtenir N-phosphonométhylglycine par oxydation de l'acide N-phosphonométhyliminodiacétique. N-phosphonométhylglycine peut être obtenu par oxydation de l'acide N-phosphonométhyliminodiacétique avec O2 ou avec un gaz le contenant, en présence d'un catalyseur de métal noble sur du carbone activé. Pour éviter les pertes de catalyseur, les améliorations de l'invention consistent à effectuer un balayage à pression avec N2, une fois terminée la réaction d'oxydation. Ce traitement permet de réduire les pertes de catalyseur de 30 % à 1 %, rendant ce traitement économiquement viable à échelle industrielle. Le catalyseur récupéré garde son activité catalytique et peut être réutilisé au moins 20 fois consécutivement. N-phosphonométhylglycine est un herbicide d'application très étendue.

Abstract: A process is provided for the treatment of water containing sulphide wherein the sulphide is oxidized in an aerobic reactor having a minimum sulphide sludge load. The minimum sulphide load is at least 10 mg of sulphide per mg of the nitrogen present in the sludge per hour, the sludge load being calculated on the basis of the sulphide oxidizing part of the biomass. The minimum sulphide load may also be defined as 25 mg of sulphide per liter of reactor material per hour. The sulphide can be largely oxidized to elemental sulphur which is then separated and reused. Waste water also containing organic matter in addition to varying levels of sulphide is purified without interference of filamentous bacteria using a two-step aerobic process. The process for sulphide removal can be used for the treatment of waste water having high levels of sulphur compounds such as sulphate, sulphite and thiosulphate by first reducing these sulphur compounds in an aerobic step. Heavy metals are removed from water by adding sulphide to the water and precipitating the metals as sulphides; the sulphide can be added by reducing sulphur compounds already present.
