Abstract: Process for hydrotreatment, in at least two stages, of a heavy hydrocarbon fraction containing asphaltenes, sulphur-containing impurities and metal impurities, in which:   a) in at least one first stage (26,27) known as hydrodemetallation, the hydrocarbon feedstock and hydrogen are passed over a hydrodemetallation catalyst, b) in at least one subsequent so-called hydrodesulphurising stage (28,29) the product from stage a) and hydrogen are passed over a hydrodesulphurising catalyst.   The invention in which the hydrodemetallation stage consists of one or more zones, each containing a hydrodemetallation catalyst operating as a stationary bed is characterised in that this or these zone(s) are preceded by two protective zones arranged in parallel (24,25) each containing a stationary bed of a hydrodemetallation catalyst, these two protecting zones operating alternately. <IMAGE>

Inventor: ASAL HANS
IPC: C02F1/48
Filed: 1991-11-20
Abstract: The electronic scale prevention device operates with two electrodes which are held at a distance from one another, between which the water to be treated is passed. An electronically controlled AC voltage, at a frequency in the range from 1 to 10 kilohertz, in the safety low-voltage range is applied to the electrodes. The control electronics have a current measuring section and a voltage controller coupled thereto. The voltage controller controls the amplitude of the AC voltage such that the current intensities acting between the electrodes are held at a specific nominal value. Thus the current intensity which is required for successful treatment can be applied irrespective of variations in the conductivity of the water with time and location. In one preferred embodiment, the control electronics additionally have a frequency sweep which ensures that the optimum treatment frequency, which differs depending on the composition of the water, is automatically generated in every case. <IMAGE>

Abstract: Appareil et procédé destinés à détecter les défauts de pose du matériau d'étanchéité par détection d'une quantité en rapport au débit du matériau d'étanchéité dans la chambre de soupape de la soupape à pointeau employée dans la machine de pose du matériau d'étanchéité. Un détecteur de proximité (120) indique à un contrôleur électronique (100) lorsque l'extrémité d'une boîte de conserve (30) est en position pour la pose du matériau d'étanchéité. Le contrôleur électronique contrôle de préférence la pression au sein de la chambre de soupape (26) pendant au moins un intervalle prédéterminé au cours de l'ouverture et de la fermeture de la soupape à pointeau (27). En cas de détection d'une anomalie de pression pendant l'un de ces intervalles prédéterminés, le contrôleur électronique produit un signal de rejet qui permet au mécanisme de transport d'éliminer cette boîte particulière de la chaîne de boîtes se dirigeant vers la prochaine station et de la placer dans une pile de rebus (38). Le contrôle a lieu pendant une période initiale d'ouverture de la soupape à pointeau et pendant une période au cours de laquelle le débit du matériau d'étanchéité est particulièrement régulier. La vitesse d'arrivée du matériau d'étanchéité dans la soupape soumise à contrôle peut également être mesurée directement ou en calculant la différence de pression mesurée aux deux côtés opposés d'un dispositif d'étranglement du débit (117).

Date Oct. 31, 1991.A method of feeding glass to a glass-melting furnace for making a vitreous material, a heated airstream containing air at a temperature in excess of 1,000 DEG  C. is passed down vertical cylinders towards the crown of the glass-melting furnace. Powdered glass batch is introduced into the vertically moving heated airstream in the lower and wider cylinder and infra-sound is applied to the vertically moving heated airstream by an infra-sound generator to vibrate the heated airstream and effect heat transfer from the airstream to the glass batch particles so that the glass batch particles are heated and the temperature of the heated airstream is reduced to a temperature below 700 DEG  C., thereby reducing the propensity of the air to produce nitrogen oxides. Fuel is subsequently added as the heated glass batch particles and the cooled airstream move downwardly towards the crown of the furnace and a stream of glass batch, burning fuel and air is passed downwardly through the crown of the furnace in a manner such that there is a direct contact between the flame of the burning fuel and the surface of molten glass within the furnace, and the glass batch is melted.

Abstract: A programmable logic array comprising cells and a bus network in which the cells are arranged in a two-dimensional matrix of rows and columns and are interconnected by the bus network. The cells are also interconnected by a two-dimensional array of direct connections between a cell and its four nearest neighbors, one to its left (or to the West), one to its right (or to the East), one above it (or to the North) and one below it (or to the South). Each cell comprises eight inputs, eight outputs, means for multiplexing the eight inputs onto two leads and logic means that operate in response to the signals on the two leads to produce output signals which are applied to the eight outputs. The bus network comprises a local, a turning and an express bus for each row and column of the array and repeater means for partitioning said buses of a given row or column so as to form bus segments. The bus network provides for transfer of data to the cells of the array without using the cells as individual wires.

Abstract: An air stream is compressed in compressor 2 and purified in unit 4. One subsidiary stream of this air is cooled in heat exchanger 10 to a temperature suitable for its separation by rectification. This subsidiary air stream is separated in a double rectification column 24 comprising a higher pressure stage 18 and a lower pressure stage 20. A secondary subsidiary air stream is further compressed in compressors 42, 44, 46 and 48. It is cooled in heat exchanger 10 to a first temperature intermediate ambient temperature and the operating temperature of the column 24. The second subsidiary stream is expanded in an expansion turbine 50 and leaves that turbine 50 at a second intermediate temperature lower than the first intermediate temperature. The expanded second subsidiary stream enters a second expansion turbine 52 at such second intermediate temperature and is expanded therein. The expansion turbine 52 feeds the second subsidiary air stream to the lower pressure stage 20 of the double column 24. Oxygen and nitrogen products are withdrawn from the lower pressure stage partly in liquid state.
