Abstract: An electrical signal observing device measures an electrical signal by applying it to an optical amplifier (10) to modulate a short pulsed light train directed through the optical amplifier (10). The electrical signal to be measured acts as a gain control for the optical amplifier (10). A photodetector (12) detects the output of the optical amplifier (10) and applies a resultant electrical signal to an integrator circuit (16) after which the signal is displayed in a display (17). The signal is displayed in a time base fashion using a sweep generated by a delay system (14) for varying the arrival time of the short pulsed light train.

Abstract: An apparatus (30) for unstacking cross-nested articles includes an elevator (60) which raises the stack (31) as articles are removed two-at-a-time from the top thereof by a continuous-chain transfer conveyor (130). The transfer conveyor carries the removed articles to a discharge station where they are dropped onto two vertically spaced-apart discharge conveyors (181,190). In one embodiment, the upper discharge conveyor (181) comprises laterally spaced-apart tracks (185) arranged so that the bottom article drops therethrough to the lower discharge conveyor (190), while the top article is caught on the upper discharge conveyor. A finger (207) on one of the conveyors turns selected articles 90° so that all articles are aligned in the same direction as they exit the lower conveyor. In another embodiment both discharge conveyors (181,220) comprise laterally spaced-apart tracks (185,225), and a turntable (230) is vertically movable between the tracks to lower the articles onto the discharge conveyors, the turntable rotating 90° between the discharge conveyors to reorient the lower article.

Abstract: The invention consists in reproducing, in particular with the aid of a light emitter (23), in the plane of an optical detector (24), the profile of an object or of a set of objects in contact or overlapping on a conveyor belt (21), for example newspapers (20), in the form of a function Y = f(X), then in examining the profile by two receivers (27, 28) delimited by two slots (30, 31), seeing to it that the intersections of the function Y and the lines representing the two receivers are reduced approximately to two points and that the distance between the two lines is the smallest possible, and finally in continuously determining the derivative Y'(X) and in activating an electronic circuit associated with the detector (24) generating an output signal proportional to the value of the derivative Y'(X). In the case of detection and of counting, the output signal is compared to a predetermined value, representative of an instantaneous variation (22) of the profile and a pulse is emitted when the output signal becomes greater than the predetermined value. The invention applies also to the detection of thread breakages. <IMAGE>

Abstract: L'invention se rapporte à un procédé et à un agencement (1) pour permettre la vidange de réfrigérants, de préférence des fréons, contenus dans des systèmes de réfrigération ou des systèmes de pompe à chaleur (9), à l'aide de pompes à compresseur à piston (2), en cas de réparation ou de mise au rebut de tels systèmes. La canalisation d'aspiration du compresseur (6) située la plus proche de celui-ci est reliée à une chambre d'un échangeur de chaleur (4), et un manodétendeur (5) est raccordé dans la canalisation d'aspiration en amont de l'échangeur de chaleur. La canalisation de pression partant de la pompe à compresseur (2) mène à un séparateur d'huile (3) et de là à une autre chambre de l'échangeur de chaleur (4). La chute de pression dans le manodétendeur (5) et le chauffage du réfrigérant dans l'échangeur de chaleur (4) signifient que le réfrigérant va atteindre le compresseur dans un état gazeux, ce qui est une condition préalable à l'action sûre du compresseur. L'augmentation de pression obtenue dans la pompe à compresseur (2) et le refroidissement du réfrigérant dans l'échangeur de chaleur (4) permettent son acheminement, de préférence à l'état liquide, jusqu'à un récipient (8).

Abstract: Samples taken automatically and frequently from the outlets of silos (4) in mixing plants, e.g. for fodder mixtures, are brought unwrapped and successively to an automatic NIR analysing station (72, 26) through a pneumatic conveyor system with substantial common pipe stretches (36) between that station and the single samplers (34). The associated risk of contamination of the samples is counteracted by taking out and conveying sample portions which are much larger than what is required for the analysis itself, and the large sample portions are not wasted, as they are returned to their silos of origin through another pneumatic conveyor system (90). It is hereby possible to operate with a real on-line analysing and thus, with computer support, to effect required changes in the mixing recipes almost immediately in response to changed analysis results. Various specialized sample handling equipment for making the system operative is disclosed.

Title: Hairspray with improved adhesion/removability upon washing.
Inventor: SRAMEK JOHN A
IPC: A61K8/81
Filed: 1989-06-01
Abstract: That which is disclosed is carboxyl radical containing resin hair setting or hair spray compositions possessing improved adhesion to the hair and which are more readily removed from the hair due to the use of certain long chain amine functional neutralizing agents containing a hydrophilic radical in addition to the amine radical as well as a long chain hydrocarbon radical such as lauryamidopropyl dimethylamine, polyoxyethylene (10) octadecylamine or a mixture of ether amines of the formula R6O(CH2)3NH2 where R is a hydrocarbon radical predominantly composed of C12 to C15 hydrocarbon radicals. Up to 40%, and preferably from 5% to 30%, of the moles of carboxyl radicals to be neutralized are neutralized with such a long chain amine and the remainder of the carboxyl radicals to be neutralized are neutralized with an amine or an alkanolamine such as aminomethyl propanol. More preferably, the compositions are hairspray compositions containing from about 10 to 80% by weight of a hydrocarbon-based aerosol propellant such an n-butane or isobutane. The long chain amine serves to improve the hydrocarbon stability of such hairspray resins.

Abstract: La brosse comprend des ensembles de poils pouvant être déplacés relativement dans un mouvement de va-et-vient, qui chevauchent transversalement une rangée de dents, sont appliqués sur les faces opposées des dents par une paire de tiges analogues à une pincette à tête plate, lesquelles sont semi-rigides et distinctes l'une de l'autre, mais reliées l'une à l'autre par une charnière; on peut ainsi les tenir ensemble comme un manche en les faisant tourner l'une par rapport à l'autre autour d'un axe s'étendant sensiblement parallèlement à leurs côtés mutuellement adjacents. Lorsqu'on les applique sur les faces des dents, on peut aussi déplacer les poils le long de la rangée, et on peut doter les poils d'une paire de guides que l'on utilise pour localiser les lignes des gencives des dents et pour diriger lesdits poils en suivant les lignes des gencives. Les guides peuvent dans ce cas comporter de minces joues s'étendant l'une vers l'autre afin de ménager des goussets de renforcement servant à stabiliser les guides pour qu'ils ne s'écartent pas lorsqu'on les fait passer le long des lignes des gencives. La brosse se prête à un emballage et un rangement sous forme compacte et peut être jetable, c'est-à-dire qu'elle peut être utilisée une ou deux fois et ensuite jetée. On peut par exemple la fabriquer sous forme d'article mince et plat comportant une charnière transversale de sorte que l'on peut la replier longitudinalement pour la rendre compacte.

Abstract: A device for applying reinforcement patches provided with glue to a web provided with transverse perforations comprises a means for tearing off the sections connected to one another by the transverse- perforation lines. Provided above the deflection roller (4) on the inlet side of a band conveyor consisting of mutually spaced continuous conveyor belts is a supply roller (6) which presses the incoming web (3) against the deflection rollers (4). A roller (7) supporting the conveyor belts (5) of the upper side is mounted with a spacing behind the deflection rollers (4) on the inlet side, this spacing being smaller than the spacing between the transverse-perforation lines of the web. The supporting roller (7) forms the counter-pressure roller for a rotating segment (8) with cylindrical circumferential surface which transports and holds a reinforcement patch (14). The radius and the speed of the circumferential surface of the segment (8) are so matched to the section lengths of the web (3) that this surface rolls between in each case two conveyor belts over part of each section while the web (3) is pressed against the counter-pressure roller (7). In this arrangement, the circumferential speed of the segment (8) and of the counter-pressure roller (7) is greater than the conveying speed of the band conveyor, so that the section (16) is torn off from the web during gluing of the patch (14) to a section.
