Granted: 1994-02-22
Abstract: ABSTRACT                  COATINGS FOR GLASS      Disclosed is an invention providing a process for form-ing a useful underlayer on a glass surface comprising directing on to the hot glass surface at a temperature of 600°C to 750°C a gaseous mixture of a silane, an unsaturated hydrocarbon compound and carbon dioxide thereby depositing a transparent layer containing silicon and oxygen on the glass surface.  Underlayers produced by the process of the invention act as barriers to the migration of alkali metal ions from the glass and are useful when an overlying layer, sensitive to the migration of alkali metal ions from the glass, is applied directly or indirectly over the underlayer.          According to a further aspect of the invention, the process additionally comprises the step of applying a layer, sensitive to the migration of alkali metal ions from the glass, over the underlayer.

Granted: 1993-10-12
Abstract: Abstract Disclosed are an electrode configuration and a method for its use with an automatic implantable cardioverter/ defibrillator.  The electrode configuration includes a catheter electrode intravenously postioned within the heart of a patient wherein one electrode, defined by the catheter, is within the right ventricle and a second electrode, also defined by the catheter and spaced from the first electrode, is within the superior vena cava region.  A third electrode, in the form of a flexible, substantially planar patch, is subcutaneously positioned outside the thoracic cavity in the region of the left ventricle.  At the time of electrical discharge, or permanently, the first and second electrodes of the catheter are connected together.  The electrode arrangement can be implanted without opening of the thoracic cavity by intravenously placing the catheter electrode within the heart of a patient and subcutaneously implanting the patch electrode between the skin and the thoracic cavity.  The automatic implantable cardioverter/defibrillator senses life-threatening arrhythmic conditions of the heart and issues at least one cardioverting or defibrillating pulse that is applied between the electrode positioned in the region of the left ventricle and the commonly connected catheter electrodes positioned, respectively, in the right ventricle and within the superior vena cava region.  The catheter also includes a pacing tip.

Title: Adaptive torque control of cutoff knife pull roll
Inventor: WELCH HAROLD D
IPC: B05D1/20
Filed: 1988-10-12
Granted: 1991-09-03
Abstract: Abstract A control system is established wherein, when there is a flow of continous web material    , an identification phase is provided by increasing the torque signal to a pull roll motor      until slippage between the pull roll      and continuous web is created at a breakaway torque point, the value of which is measurable.  The pull roll motor is then caused to be driven by a signal which creates a motor torque output which is of a value less than the breakaway torque point.  Thus, no slippage can occur. As the motor is driven at the lower torque value, a calibration phase is entered wherein an encoder output of the pull roll is properly equated with that of a measuring wheel    , this phase occuring at a time when there can be no slip between the web-roll interface. The identification-calibration process can be repeated as often as desired.  The control system further includes the ability to cause acceleration of the pull roll after the web has been severed upstream to thereby accelerate the tail or downstream portion of the severed discontinuous web until a desired gap is created for use in a slitting device    .  At this point, which is subsequent to the identification-calibration phases, the control returns the motor input to the lower torque value.

Title: Method and apparatus for serving the passenger traffic at the main floor of an elevator installation
Inventor: BRENNER RICHARD
IPC: B66B1/20
Filed: 1989-01-05
Granted: 1993-02-16
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for the control of the dispatch of elevator cars from the main floor are implemented in a plurality of algorithms performed by a process computer.  A first algorithm for an elevator group receives data representing the measured arriving and departing building-filling passenger traffic from sensors.  The first algorithm determines the traffic requirements and the actual departure load of the elevator group from this data and various constants, and determines the transport capacity of the elevator group.  The transport capacity is assigned to second algorithms associated with the elevator cars and corresponding to the nominal load of each respective car.  Based upon the assigned transport capacity and the round trip time of the respective elevator car, the second algorithm calculates the nominal departure load.  Dependent on the nominal departure load and the actual departure load, the second algorithm calculates a corrected departure load with which the elevator car should be loaded.

Abstract: OLEFINIC OLIGOMERS HAVING LUBRICATING PROPERTIES        AND PROCESS OF MAKING SUCH OLIGOMERS                          ABSTRACT          Novel lubricant compositions comprising polyalpha-olefins are disclosed having high viscosity indices with low pour point. The compositions are characterized by a uniform molecular structure with low branch ratios.  The invention describes a liquid lubricant composition comprising C30-C1300 hydrocarbons, said composition having a branch ratio of less than 0.19, weight average molecular weight between 300 and 45,000, number average molecular weight between 300 and 18,000, molecular weight distribution between 1 and 5 and pour point below -15°C. 1-decene trimer comprising 9-methyl, 11-octylheneicosane and 11-octyldocosane is disclosed.  The lubricant compositions are produced by contacting said alpha olefin with a supported solid reduced group VIB (e.g., chromium) catalyst under oligomerizaeion conditions at a temperature of about 90 to 250°C to produce liquid lubricant hydrocarbon.  The hydrogenated lubricant range hydrocarbon product has a viscosity index of about 130 to 280 and a viscosity up to about 750 mm2/s(cs).  The process is particularly useful where the starting alpha olefin consists essentially of olefinic hydrocarbons having 8 to 14 carbon atoms or mixtures thereof, wherein the process conditions include a reaction temperature of about 100 to 180°C; and wherein the support catalyst includes porous inert silica.

Abstract: ABSTRACT           The present invention relates to a process for uncoupling signals from at least one sub-area of the supplementary signals and to couple signals into at least one sub-area of the supplementary signals of transport modules of a synchronous digital signal hierarchy as in CCITT Draft Recommendations G.70X, G.70Y, and G.70Z.  When uncoupling, this task has been solved in that a sub-area of the secondary signals is uncoupled from the transport module in a demultiplexing and spreading system, and during a period of time is spread within the framework.  The spread signal is broken down, for example, into the secondary signals of the selected sub-area that are associated with the transport modules of the lowest stage of the hierarchy that are contained in the transport module.  For coupling, these steps of the process are carried out in the reverse and opposite sense. These secondary signals are moved onto the lines of the bus. Control signals, fed in externally or generated in the demultiplexing and spreading system, are transmitted in a sub-bus. After addresses have been input, bytes or groups of bytes can be picked off the bus through the customer intersection points and undergo further processing.  This process can be applied in synchronous digital signal hierarchies such as NNI (network node interface).

Abstract: ABSTRACT          A DEVICE FOR MEASURING FLOW     Fluid delivery equipment, for example for distributing herbicide, is calibrated to provide a correct flow rate by performing a test cycle in which the fluid flows into a measuring device for a predetermined time, after which the volume of fluid in the measuring device is established to determine whether or not the flow rate corresponds to the desired flow rate.  The measuring device establishes a flow path having two reverse bends (36, 30) with the reverse bend (36) bypassed by a vent hole (32).  The level of liquid in the measuring device after a test is, for example, established by means of a graduated scale provided on a card (40) which is removably attached to a package containing the fluid to be distributed.
