Abstract: This invention relates to a method of restoring the activity of a gallium/aluminosilicate catalyst system. Such systems get deactivated in use. Such loss of activity in long term use can only be restored by subjecting the system to a sequence of oxidation and reduction treatments. The catalyst systems are useful for hydrocarbon conversion reactions, especially for dehydrocyclodimerisation of paraffins and olefins to aromatics.

Abstract: Un dispositif de maintien automatique du niveau d'un fluide détecte le niveau d'un fluide pour déterminer s'il est en dessous d'un niveau critique et, s'il en est ainsi, il assure automatiquement le remplissage avec du fluide jusqu'à ce que le niveau critique du fluide soit rétabli. Le dispositif de maintien automatique du niveau d'un fluide (10) comprend un corps (20), une sonde (30), une bague supérieure filetée (40), une bague inférieure filetée (50), un évent (60), une console de montage (70), un tuyau flexible (80), un premier tube étanche à l'air (81), et un second tube étanche à l'air (82). Le dispositif de maintien du niveau du fluide (10) coopère avec un réservoir supérieur étanche à l'air (90) (ou réservoir d'alimentation) et une enceinte de lubrification, un carter d'huile, ou autre type de réservoir inférieur de fluide (100). L'extrémité inférieure de la sonde (30) est ajustée pour se trouver à un niveau de fonctionnement désiré (90). Lorsque le niveau du fluide dans le réservoir inférieur (100) tombe en dessous de la pointe de la sonde (30) dans le corps (20), le fluide provenant du réservoir supérieur (90) s'écoule vers le bas en descendant au travers du corps (20) dans le réservoir inférieur (100). Lorsqu'une quantité suffisante de fluide fait remonter le niveau dans le corps (20) pour recouvrir la pointe inférieure de la sonde (30), l'écoulement cesse.

Abstract: The present invention relates to a communication system wherein a word processing display terminal is transmitting documents to one or more data receiving terminals which also may be word processing terminals. In such communication systems, it is customary to arrange the documents to be transmitted in a sequential queue. The present system has the capability of dynamically altering the queue to either revise documents before their transmission, remove documents, substitute others without affecting or interrupting the transmission. Transmission continues as a background function of the equipment while the operator at the transmitting display terminal has the capability of accessing documents in the queue which have not been transmitted as yet, altering, revising, otherwise changing the queue positions of these documents prior to transmission.

Abstract: A cylinder head, for a water cooled internal combustion engine, which reduces the thermal stresses. The gas-changing channels and the oil-return channels are located on one side. A main water overflow, in conjunction with an oppositely located auxiliary water overflow, makes possible a precise or directed flow along the valve land portion and around the turbulence chamber or the injection nozzle channel, whereby the flow is kept along the cylinder head bottom by a roof-shaped wall on the side remote from the cylinder block. The strength of the cylinder head is increased, and the oil removal is improved, by associating an oil-return channel with each cylinder. Specially shaped cylinder head screw channels increase the compression or pressure against the combustion chamber walls and effect a more uniform pressure distribution. A more favorable sealing behavior is attained by compensation or expansion curvatures in the cylinder head cover plate.

Abstract: A non-woven fabric having a pattern defined by an array of discrete areas having a reduced fibre density but which are substantially free of perforations is produced by supporting a freshly wet laid web of the non-woven fabric on a porous surface and directing spaced jets of fluid against the unsupported side in order to displace fibres within discrete areas whilst maintaining in position a proportion of fibres that are within those areas and that are adjacent the porous surface. The fabric web may be supported on a Fourdrinier wire (1) and the jets of fluid (e.g. water) may be directed through the apertures in a perforated cylinder (6), the fluid being supplied under pressure from a water-knife device (11). The apertures in the cylinder (6) preferably have a cross-section that increases in the direction of the water jets. Vacuum may be applied through the Fourdrinier wire (1) by means of a vacuum box (10) and vacuum may also be applied within the cylinder (6) from means (17) in order to remove excess water from within the cylinder (6).

Title: Power supply circuitry in 2-wire thermostats
Inventor: KOMPELIEN ARLON D
IPC: H02J7/02
Filed: 1982-05-05
Abstract: A 2-wire thermostat is connected across a power source T1 and a load L. A sensing and signal processing circuit SSP, powered by a battery B1, opens and closes a switch S2 to de-energize and energize the load. The battery B1 is charged from the secondary T2S of a transformer T2. With S2 open, current flows through a large primary winding T2Pl of T2 (and through the small primary winding T2P2), down and up on successive half-cycles from T1, so energizing T2S. As the initial part of each half-cycle provides an appropriate charge for B1, the output of a comparator COMP changes to open switch S1A or S2A to terminate current flow for the latter portions of the half-cycles. Dissipation and heating of the thermostat is therefore minimized. With S2 closed, a heavy current flows through the small primary winding T2P2 so energizing T2S, but winding T2Pl now acts as a secondary and is energized in reverse. Switches S1A and S2A therefore allow current flow in T2P1, under control of COMP, in the latter portions of successive half-cycles. This current flow in T2P1 is a short-circuited loop flow, and therefore prevents power transmission through T2 to the battery B1 except during the initial portions of the half-cycles.

Abstract: The fuel required to provide the energy for compressing a gas can be reduced by compressing the gas substantially adiabatically through a pressure ratio of at least 2.5:1 in a compressor, cooling the hot compressed gas by heat exchange with water at superatmospheric pressure, further heating the water to produce super-heated steam and using the superheated steam to drive the compressor. The total amount of fuel consumed can be considerably less than that used for compressing gas conventionally (i.e. substantially isothermally).

Abstract: A fusion reaction system is provided wherein ions from two sources (16,17) are forced by passage through magnetic and electric fields to travel toward each other in opposite senses and directions under confinement to common helical paths at a common radius in a cylindrical reaction zone (29) by radial electric fields. The ions are bunched along said helical paths to establish a plurality of concentrations of the ions located at spaced points along the paths with the points being the same for ions from both sources. Structure in the reaction zone (29) is arranged for establishing local variations in the radial electric fields to produce the localized concentrations of ions as they traverse their helical paths. Further, means may be provided to velocity modulate the ion sources for producing standing waves along the reaction paths having velocity nodes located at points in the reaction zone where the localized concentrations occur. Variable voltage sources are connected to modulate the velocities of ions from the two sources for producing standing waves in the reaction zone having velocity nodes spaced the same as the spacing between the localized concentrations. Phase adjustment means provide for positioning the velocity nodes at the same points as the points at which the localized concentrations occur.
