Abstract: An improved method and apparatus for the safe handling of alkylation catalyst. The method and apparatus comprises a process vessel which serves a dual function of storing alkylation catalyst and of recontacting alkylation hydrocarbon product with alkylation catalyst. Alkylate product is passed through an eductor-mixer device which intimately mixes alkylate with catalyst. This mixture flows into the dual function recontacting vessel where a phase separation of the catalyst and alkylation hydrocarbon product takes place. Conduits are provided to connect the process reactor, cooling heat exchanger, settler, and interconnecting piping so as to allow the quick release of pressure from the combination storage-recontacting vessel and subsequent draining of catalyst into the vessel by use of gravitational force. The method and apparatus consists of a physical arrangement and use of alkylation process equipment in a manner which allows the use of a single vessel for both storage of alkylation catalyst and recontacting of alkylation hydrocarbon product. The apparatus and method is a safety feature which allows the transfer by draining of catalyst from the alkylation process vessels into the storage vessel by the sole use of gravitational energy motive force.

Abstract: Disclosed is a switch that allows a peripheral device (106), such as a PCL printer, to be shared by multiple computer systems (102, 108). The switch (116) connects to each of the computer systems (102, 108), and also to the peripheral device (106) being shared. The first system (102) is considered the primary user of the peripheral device (106), so when the second system (108) requests access to the peripheral device (106), the switch (116) causes the peripheral device (106) to save its state temporarily while the second system uses the device. When the second system's (108) use is complete, the switch (116) causes the peripheral device (106) to restore its state to the last state established by the first system. Therefore, the first system (102) need not know that the other system used the peripheral device (106), since the state of the peripheral device (106) appears unchanged from the last time the first system (102) used the device.

Abstract: The present invention relates to a method for mounting clamps (1) on a band (2) which is movable in its longitudinal direction, the band (2) being deformed transversely to the longitudinal direction in such a manner that the spacing of the band edges (3, 4) becomes smaller than the band width and the clear spacing of the holding elements (5, 6) arranged on the clamp (1), and the part of the band (2) lying between the band edges (3, 4) is arched forward out of the band plane defined by the band edges (3, 4), the band edges (3, 4) are brought between the holding elements (5, 6) and the deformation is essentially stopped again so that the band edges (3, 4) essentially readopt their original spacing and the clamp (1) comes into frictional engagement with the band (2), and a corresponding device. In order to provide a method and a device of this type, which make possible rapid and safe clamping on of the clamps and are operationally safe and at the same time can be manufactured relatively economically, it is proposed according to the invention that the deformation of the band (2) is initiated by bringing the clamp (1) into the clamping position and that the release of the deformation is initiated either after a rigidly fixable time as of initiation of the deformation or by a switching element which responds directly or indirectly to the deformation of the band (2). <IMAGE>

Abstract: 57 A holding circuit used in a pedestal level clamp circuit of a color television receiver. By using base current of a transistor as charging current of a capacitor, a large time constant is obtained. Also, in case the voltage lower than the reference voltage is held, base current of the transistor is used as discharging current to discharge slowly. Furthermore, though a charging transistor of the capacitor must be a PNP type and a discharging transistor must be an NPN type, it is designed not to be influenced by the difference in current amplification factors of the two tvpes.

Abstract: The heel support device has a non-expansible tension member (27) which can be moved in all directions and is designed in the manner of a belt, being secured by one end to the ski and by the other end, by means of a clamp (40), to a pin (47) on the boot heel. By means of this clamp (40) the tension member can be released at will, and can be pulled off from the pin (47) in the event of the occurrence of a tensile force acting substantially in the direction of the boot sole. On the tension member (27), two parts (81.1, 81.2) of a connecting piece (81) are secured at a distance apart so as to be adjustable. The two parts form a connecting piece designed in the manner of a push-button. In the closed state of the connecting piece, a loop (85) of the tension member remains, which, after the release of the connecting piece under the action of an increased tensile force, results in a lengthening of the tension member (27), so that the boot heel can again be lifted away from the ski.

Abstract: A method and apparatus are provided for allocating tolerances. A total tolerance is specified (218) to be allocated among a plurality of variable tolerances each having an associated assembly feature. For each associated assembly feature, an associated first tolerance point is defined at which a further decrease in a stringency of the variable tolerance fails to significantly decrease a cost of achieving the variable tolerance. For each associated assembly feature, an associated second tolerance point is defined at which a further increase in the stringency begins to substantially increase the cost of achieving the variable tolerance. For each associated assembly feature, an associated third tolerance point is defined at which a further increase in the stringency is not substantially achievable. The total tolerance is allocated (for example: 232, 254, 266) among the variable tolerances, such that the variable tolerances substantially satisfy a first predetermined relationship relative to the total tolerance, and such that each variable tolerance substantially satisfies a second predetermined relationship relative to its associated tolerance points.

Abstract: A method of producing an oxide glass thin film includes a process to obtain a transparent glass film, in which volatilization of additives in a porous film deposited is effectively suppressed and which can provide an oxide glass thin film having a desired arrangement of refractive index with a low optical loss. The method is for producing an oxide glass thin film, in which glass fine particles mainly containing SiO₂ with additives are deposited on a substrate to form a porous thin film and then heated to form a transparent glass film. In the method, vapor of oxides of additive components is mixed in an atmosphere in which the porous thin film is heated to form the transparent glass film, whereby stopping the volatilization of the additives in the porous film deposited, preventing diffusion of the additives added to a core layer, and preventing the volatilization of glass transition temperature lowering components of additives (P₂O₅, B₂O₃, GeO₂, etc.). By these, a desired arrangement of refractive index may be obtained, and an oxide glass thin film may be obtained while lowering the optical loss such as the optical scattering, which could be caused by bubbles in an unsintered portion.
