Filed: 1990-12-27
Abstract: When steaming food using a steam-cooking appliance (1) with an electrically controlled enclosed steaming area, a water supply line (13) with valve and outlet opening, with a heater (10) and with a fan blade wheel (8), which is arranged relative to the outlet opening and the heating elements (10) in such a way that water (14) leaving the outlet opening can be sprayed by the fan blade wheel (8) and conveyed towards the heater (10), the problem exists that the formerly commonly used constant water supply results in excessive power and water consumption. It is proposed that follow-up devices should be provided and connected to the control unit in such a way that the water supply is essentially continuous when the heater is switched on, and that after the heater is switched off the water supply is maintained only until such time as the heater falls below a preset temperature.

Abstract: In the transmission of digital video data signals, for example, in a digital video tape recorder, a luminance signal and first and second chrominance signals, such as R-Y and B-Y, are individually sampled to provide respective digital luminance data signals and first and second digital chrominance data signals for forming a high-definition video picture. Time code data signals representing the corresponding frame including the sampled signals are provided as individual sets of identical signals. The digital luminance data signals and the first and second digital chrominance data signals are divided into respective sets (21,22,23) thereof which each consist of two successive data signals. The sets of time code data signals, digital luminance and first and second digital chrominance data signals are distributed into a plurality of transmission channels (41-48) in such a manner that each set of digital luminance data signals is interleaved between sets of the first and second digital chrominance data signals, respectively, in each of the transmission channels and that each of the sets of time code data signals is likewise distributed into each of the channels. Further, one of the two successive data signals in each of the sets of digital luminance data signals, first and second digital chrominance data signals and time code data signals is inverted for obtaining the complement of the one of the two successive data signals in each set which   has been inverted, thereby substantially minimizing any DC or low-frequency component in each of the transmission channels.

Abstract: Air is separated into oxygen and nitrogen in rectification columns 28 and 30. A stream of nitrogen is withdrawn from the top of the column 30 through an outlet 54, is warmed to about ambient temperature by passage through heat exchangers 34, 46 and 24, and is then heated at a pressure in the range 2 to 7 atmospheres absolute by heat exchange in heat exchanger 56 with a hot stream of fluid initially at a temperature of less than 600°C without said fluid undergoing a change of phase. The resulting hot nitrogen is then expanded in turbine 58 with the performance of external work, e.g. the generation of electricity.

Abstract: Continuous manufacture of 1,1,1-chlorodifluoroethane from 1,1,1-trichloroethane and hydrofluoric acid by liquid phase reaction in the presence of at least one fluorination catalyst. According to the invention the operation is carried out at an absolute pressure of between 6 and 30 bars and at a temperature of between 50 and 120 DEG C, the catalyst content of the reaction mixture, expressed as weight percentage of metal, being between 0.05 and 10% and its content of organohalogen by-products outside 140 series being regulated at a value of less than 40% by weight. This process makes it possible simultaneously to obtain a high degree of conversion of hydrofluoric acid, to minimise the coproduction of 1,1,1-trifluoroethane and of organohalogen by-products, and to make it easier to recover the hydrochloric acid formed.

Abstract: Disclosed are compounds of the general formula: 
R-O-Ar-COS-Ph-COO-R′ 
characterized by the presence of the thioester (-COS-) core and wherein R is an alkyl group with typically 8 to 16 carbon atoms, Ar is a substituted aromatic core group such as 1,4-­benzene, 2,6-naphthalene, 4,4′-biphenyl, or 4,4′-­diphenylethane, and R′ is a chiral branched alkyl group such as the 1-substituted cases 1-methylpropyl through 1-methyl­octyl or 2-substituted case such as 2-methylbutyl. These materials or their mixtures possess ferroelectric phases and as such are of interest for electro-optical applications. In certain cases specific materials are of particular interest due to the existence of stable ferrorelectric phases near room temperature with large polarization density and fast electro-­optic response.

Abstract: Un logement (11) d'un boîtier à piles (10), contient, en plus d'éléments de piles (14-16) classiques, un convertisseur de tension (75). Le convertisseur de tension (75) est interposé entre les éléments de piles (14-16), et des contacts de sortie extérieurs (29, 30, 100) dudit logement (11). Ledit convertisseur de tension (75) régule la tension de sortie appliquée aux contacts de sortie (29, 30, 100) du boîtier à piles (10), de sorte que la tension d'alimentation de ce dernier (10) reste à une valeur prédéterminée, laquelle est indépendante de la tension fournie par les éléments de piles (14-16) au convertisseur de tension (75), et ne varie pas pendant le cycle de décharge desdits éléments de piles (14-16). La tension des piles excédentaire disponible notamment pendant la partie initiale du cycle de décharge des éléments de piles (14-16) est efficacement convertie à la valeur de tension de sortie prédéterminée, ce qui réduit le courant total fourni par les piles (14-16), afin de prolonger la vie utile du boîtier à piles (10) entre les charges.

Abstract: The method is used to correct the error in measurement which occurs because of the deflection of a probe (6) attached to a tilt-and-turn joint (2) under its own weight. 
<??>For this purpose, a parameter (b) describing the rigidity of the tilt-and-turn joint (2), or of a probe extension (5) mounted thereon, is determined which is characteristic for the relevant probe configuration, and is entered into the memory of the computer of the co-ordinate stage. 
<??>The deflection B ( alpha ,ss), differing in magnitude according to the angle ( alpha ,ss) set, is then calculated from this for all angles to be set and is taken into account in the formation of the co-ordinate value. 
<??>Calibration of the tilt-and-turn joint in the different angle settings is thus unnecessary.

Abstract: The present invention concerns a heterogenic catalyst suited to the metathesis reactions of hydrocarbons in particular. Such a catalyst includes an inorganic oxide support, typically consisting of γ-alumina, having rhenium oxide absorbed onto its surface. The catalyst in accordance with the invention is prepared by vapourizing a precursor of rhenium, preferably rhenium heptoxide, preferably at a temperature of at least 160°C, and routing the vapour into a reaction chamber where they are brought to interaction with the support material. The temperature of the support material is kept above the condensation temperature of the vapour and simultaneously sufficiently high so as to attain the thermal activation energy level necessary for the generation of bonds between the rhenium oxide and the support material. According to the invention, the process is carried out preferredly within a temperature range of approx. 160...500°C. The rhenium oxide precursor is introduced in vapour phase in an amount, which is at least equal to or, preferably, in excess of the number of available binding sites on the support material surface. The activity of a catalyst even with a very low content of catalytic metal species is as high as the activity of a catalyst of appreciably higher content of rhenium that has been prepared by the methods of conventional technology.

The fibrous reinforcing skeletal material is substantially completely encapsulated or embedded in the cured foam system and occupies at least 10% of the maximum or mean thickness of the finished uncompressed article. The methods of the present invention relate to steps of (1) providing a urethane mold (10) with at least one cavity; (2) placing a three dimensionally random or semi-random fibrous preform (26) securely in the mold; (3) adding a urethane foam system; and (4) foaming the preform in place to create a unitary foam article. The materials provided by the processes of the present invention are particularly useful in furniture, bedding and other environments where reinforced flexible urethane foam is employed.
