Title: Multiplexing device for combining two frequency bands
Inventor: BUI HAI NHU
IPC: H01P1/161
Filed: 1983-06-10
Granted: 1988-04-07
Abstract: A multiplexing device for a multiband antenna. It essentially comprises, in series from the coupling input to the antenna: a common guide permitting the passage of a high frequency band and a low frequency band, into which issue by means of two coupling holes staggered with respect to one another along the common guide, two orthogonal guides which constitute the inputs for the two orthogonal polarizations of the lower band; a junction; and a polarization duplexer for the higher band. The coupling holes contain resonators forming a short-circuit for the higher band frequencies. The common guide contains, viewed from the antenna coupling input, between the first and second coupling holes, a first filter which reflects towards the first coupling holes the waves in the lower band and having the polarization of the wave passing through the first hole and, between the second coupling hole and the junction, a second filter which reflects towards the second coupling hole the waves located in the lower band and having the polarization of the wave to pass through the second hole.

Abstract: A process controlling the use of a document reserved to the titleholder along or to the authorized bearer, and is characterized by consisting prior to the activation of the document in integrating into a predetermined zone of the document a predetermined and random coded transcription of a set of letters and/or digits constituting a secret "word" known only to the titleholder, the coded data being spread across a matrix of n rows and p columns, in comparing at the time the document is used the coded data with a "word" issued by the document bearer following the transcription in the same code, and in determining and displaying whether in there is coincidence or not. The process applies in particular to checks or the like. The invention also relates to the documents and the coding and reading means designed or developed to implement this process.

Title: Coating apparatus
Inventor: LE MAITRE RICHARD BRUCE CARLYL
IPC: B05C11/04
Filed: 1984-08-06
Granted: 1987-12-23
Abstract: A hot knife coater comprises a pair of thicknesser blades defining between them a thicknesser gap through which a web to be coated passes. Each blade is connected to a downwardly depending mid-portion of a blade support by means of a number of longitudinally spaced blade holders. This minimizes bowing of the blade supports as a result of heat conducted to the blade supports from the respective blades. The blade holders connecting one of the blades to the respective blade support are adjustable so as to permit local adjustment, in the region of each blade holder, of the gap. Each blade support is mounted so as to be pivotal about a longitudinally extending pivot axis and is biased by a spring against a stop. This permits automatic opening of the gap to let a seam in the web through the gap, thus eliminating the need for operator intervention.

Title: An improved sootblower apparatus for use in a boiler and method of operating the same
Inventor: HAMMOND CHARLES WESLEY
IPC: F28G3/16
Filed: 1984-10-05
Granted: 1988-02-11
Abstract: A sootblower of the long retracting variety including a drive system (16) which simultaneously rotates the lance tube (12) as it is inserted and withdrawn from the boiler. A variable speed drive is employed to modulate the rotational speed of the lance tube in accordance with the projected distance of the lance tube such that the lance tube is driven faster at intermediate lance tube projected distances thereby optimizing the cycle time of the sootblower. The modulated rotational speed of the lance tube is maintained at all projected distances below the critical speed which varies as a function of projected distance and the sootblower type. By driving the lance tube at certain projected distances at a rotational speed above the critical speed for other projected distances, the translational speed is increased and cycle time reductions are realized as compared with the prior art wherein the lance tube is driven at a constant speed below the minimum critical speed. The lance tube speed may be varied upon retraction and operated at constant speed for insertion or vice-versa or the speed may be varied both on insertion and retraction, as the cleaning requirements of a particular application requires.

To protect this guide track (9) disposed on the first machine part (1) from the track dust, grease, oil and the like, it is disposed in an almost completely closed guide channel. This guide channel is accessible only from the top through a slot engaged by guide elements (14) of the other machine part (2). The slot is covered on the one hand by the housing of machine part (2), and in the area outside of this housing it is closed by a belt (4).

Abstract: A container having an upstanding rim running around the periphery of its top lid and a pre-cut dispensing aperture therein is provided with an integral pouring lip/drain surface between the container's rim and dispensing aperture. The container is also provided with an easy-open/reclosing element that is preferably hingedly attached to the container's top lid. The easy-open/reclosing element has a depending plug that is shaped complementary to the dispensing aperture. When pressed into the aperture, the plug initially seals the container and, if desired, is used to reclose the aperture after opening. In a particularly preferred embodiment, the easy-open/reclosing element is provided with a U-shaped flange that is shaped complementary to both the top lid's pouring lip and upstanding rim. When the easy-open/reclosing element is in its closed position, this U-shaped flange receives the container's pouring lip and rim and thereby protects them from dirt and dust contamination. This sanitary feature is particularly appealing if a customer desires to drink product directly from the container.

Abstract: The apparatus is provided with a flow meter for the rate of discharged water, with an additive mixed in, as well as a flow meter for additives before they are fed into a mixer, in which they are mixed in with the water. Also provided is a preselection device for preselecting the desired additive value. In addition, a circuit arrangement for calculation of the desired rate of additive as a function of the respective water discharging rate is provided. In a comparison arrangement, the deviation of desired additive value and actual additive value is determined and from it an adjusting signal for at least one adjusting valve is produced in a controller to control the additive feed rate. By means of a function generator, the output signals of which are a function of the desired value of the position of the adjusting valve and/or the actual value of the adjusting valve, the adjusting signal can be amplified or attenuated in certain characteristic ranges, so that it can be adapted to the characteristic of the adjusting valve. To increase the dosing accuracy and to achieve a faster control response, two or more final control elements, which can be activated in various flow rate ranges, may be provided for controlling the additive feed. <IMAGE>
