Title: Method for continuously controlling the water content  of alkylation catalysts
Inventor: MAYER IVAN
IPC: B01J27/00
Filed: 1976-11-23
Granted: 1980-09-16
Abstract: ABSTRACT OF DISCLOSURE          The water content of an alkylation catalyst comprising water and an acid selected from the group consisting of sulfuric acid and fluorosulfuric acid is determined continuously by contacting fuming sulfuric acid with said catalyst in a flow ratio  sufficient to maintain the mixture thus formed at the point of incipient fuming.          The presence of SO3 evolved therefrom is determined by use of an SO3 detector.  The flow ratio at the point of incipient fuming is a direct measure of the amount of water in the alkylation catalyst stream.  The water content thus measured is then compared to the desired water content and a signal corresponding to the deviation is used to vary the rate of fresh acid makeup to the alkylation reaction zone so as to maintain the desired water content of the catalyst in said reaction zone.

Abstract: DIGITAL CONTROL SYSTEM FOR D. C. MOTORS                 Abstract of the Disclosure A phase-control type of closed-loop control system for motors. A reference signal generator generates a digital reference signal having a binary value which varies between first and second values n times during each a-c input voltage cycle. An error signal generator generates a digital error signal having a binary value which varies in accordance with the difference between the desired and actual values of a motor variable such as armature current. The most significant bits of the digi-tal error signal are utilized to select the angular range within which firing signals will be applied to a phase-controlled rectifier network that is arranged to drive the motor. The least significant bits of the digital error signal are compared with the digital reference signal to determine the time, within the selected angular range, when firing signals will be applied to the controlled rectifier network. By use of this technique, the control system provides both precisely timed control events and a range of control which extends over the entire motoring and inverting regions of motor operation.

Abstract: ABSTRACT OF THE DISCLOSURE         There is described a glass composition for use in corrosion-resistant, hermetic glassceramic-to-metal seals, the composition having the property of sequentially fluidizing, sealing and ceraming during a single heating step, comprising about 25.0 - 32.0% by weight ZnO, about 2.5 - 10.0% by weight A12O3 and about 30.0 - 60.0% by weight SiO2 together with optional fluxing and/or nucleating agents.  Also described is a method of making a plug seal having a metal pin electrode mounted by a cor-rision-resistant, hermetic glassceramic-to-metal seal in a surround-ing metal collar, comprising the steps of positioning a glass composition preform between and in proximity to the pin and the collar, within a controlled atmosphere enclosure, rapidly heating the metal pin and collar to cause the glass preform to heat, by con-duction and radiation, so that it flows between and adheres to the pin and collar, and then cerams, and cooling the plug seal within the controlled atmosphere enclosure  to room temperature.          The method, at least when using a glass composition as described above, avoids the necessity of separate heating steps in order to first fluidize and subsequently ceram the glass.  Further described is apparatus for use in making a hermetic plug seal having a metal pin electrode mounted by a corrosion-resistant glassceramic-to-metal seal in a surrounding metal collar, comprising a R.F. induc-tion coil mounted about an oven body having gas inlet means and a loading port, a jig positionable within said oven body, for holding a glass composition preform between and in proximity to the pin and the collar, a gas-permeable closure for sealing said loading port, a generator and source of power for said R.F. induc-tion coil, and a source of inert gas in communication with said gas inlet means.  The plug seals exhibit good corrosion resistance, particularly in a corrosive environment such as a 30% KOH electro-lyte utilized in Ni-Cd batteries.

Abstract: FABRICATION OF MESA DEVICES BY           MBE GROWTH OVER CHANNELED SUBSTRATES            Abstract of the Disclosure Parallel channels are separated by ridges formed in a semiconductor body in such a way that each channel is wider at its base than at its top.  Molecular beam epitaxy is used to deposit semiconductor layers on the ridges and in the channels.  Because each channel is narrower at its top than at its base, the configuration is essentially self-masking.  That is, the layers in the channel are physically separate from those on the ridges, as would be metallic contacts deposited on the layers.  This technique is employed in the fabrication of a plurality of self-aligned, stripe geometry, mesa double heterostructure junction lasers.
