Abstract: ABSTRACT OF THE DISCLOSURE           A focus initialization system is provided for optical data recording of the type in which an objective lens relatively near to the optical recording media is moved back and forth in comparatively small excursions to maintain focus for the read beam and write beam on the media. This system initializes or loads a conventional focusing system by starting the objective lens at a position at the far end of its travel limit, preferably with the objective lens furthest from the optical media.  The objective lens moves slowly towards the optical media while the system operates to detect when a near focus condition exists.  Known focusing detection systems produce a bipolar output voltage having a peak on either side of the exact focus point when a near to focus condition is achieved.  The present system detects when the objective lens is at a near to focus condition in the range between bipolar voltage peaks on either side of the focused point.  When the objective lens is near to focus where the known focusing system can maintain focus, the present system switches on the known focusing system.  The present system monitors the focus condition and if a far out of focus condition occurs, waits a short time interval before activating a warning indication.  Also, the present system waits a short time interval when a near to focus condition exists before activating the known focusing system in order to make sure that the near to focus condition is stable.

Abstract: Abstract of the Disclosure A method and apparatus for forming an electrical connector having a first hollow cylindrical portion of a first outside diameter and a second hollow cylindrical portion of a second outside diameter which is less than the first outside diameter, are provided in which two successive extrusion operations are performed.  In the first extrusion operation, a billet of ductile metal is placed in a first die and an intermediate billet is formed by back extruding the first portion of the connector over a punch while forward extruding a part of the billet in the die to form a portion of reduced diameter approximately equal to the second outside diameter of the electrical connector.  In the second extrusion operation, the intermediate billet is placed in a movable die section and the intermediate billet and the movable die section are moved downward from an initial position by means of a finish punch.  The finish punch contacts the intermediate billet and is received within a first cylindrical recess defined by the billet.  Downward movement of the movable die section forces the portion of reduced diameter of the intermediate billet over a stationary punch, thus forward extruding the second cylindrical portion of the connector.  The finish punch is then retracted from the connector, and the connector is ejected from the movable die section by raising the stationary punch with respect to the movable die section.

Abstract: APPLICATION OF                    EUGENE L. SZONNTAGH        METHOD FOR OPERATING A GAS ANALYZING SYSTEM              AND APPARATUS UTILIZING THE SAME                          ABSTRACT   A method and apparatus for a gas analyzing system uses a rotary valve for mixing fuel gas to be analyzed for calorific content and air,  The speed of the rotary valve which determines the air-fuel ratio is controlled by a controller sensing combustion products resulting from a combustion of the fuel gas and air mixture.  The control of the air-fuel ratio is arranged to produce a substan-tially stoichiometric combustion at which condition the calorific content of the fuel gas is determined from the controller operation.  The air supplied to the rotary valve is initially pumped through a dehumidifier for removing water vapor to minimize the error in the measurement of the calorific content of the fuel gas produced by the entrained water vapor.  The dehumidifier includes a labyrinth in the air flow path which is cooled below the dew point temperature of the air stream but above the freezing point of water to produce a condensation of the entrained water vapor on the cooled surface.  The condensed water is allowed to drain from the dehumidifier by a drain within the cooled environment while the dehumidified air is subsequently applied through a pressure regulator to the rotary mixing valve.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to a process for converting a feedstock comprising aliphatic or alicyclic hydrocarbons into aromatic hydrocarbons by bringing into contact in a fluid phase a mixture of the feedstock and an oxidising agent other than molecular oxygen or a gas containing molecular oxygen into contact with a solid acidic catalyst having Brönsted acid sites.  The process is particularly suitable for converting methane, ethane and/or ethylene into aromatics.  The solid acidic catalyst with Brönsted acid sites may be an aluminosilicate zeolite with a silica to alumina ratio greater than 12:1.  The oxidising agents other than molecular oxygen or a gas containing molecular oxygen may be selected from nitrous oxide, sulphur trioxide, hydrogen peroxide, ozone, nitric oxide, carbon dioxide and nitrogen oxyfluoride. The process yields high octane value aromatics even from methane at relatively low conversion temperatures.

Abstract: SENSING SYSTEM FOR MEASURING A PARAMETER          ABSTRACT:    A parameter, such as the current flowing through a conductor, is measured by initially passing an energiz-ing magnetic flux through a hall element (12) to produce a hall voltage proportional to the sensed parameter.  To eliminate temperature, aging and non-linear effects normally associated with a hall element, the amplitude of the hall voltage is effectively ignored and only its polarity is detected  (15) and employed to control the operation of an integrator (19) to develop a cancelling current (21-23,32,33) to establish an equal, but oppo-site direction,  cancelling  flux  in the hall element. With a zero net flux,  the integrator will hold the cancelling current at the level required to balance out and cancel the initial energizing flux.   Since the cancelling  current needed to null the energizing flux will be proportional to that flux, the current may be used to produce (23) a control voltage to represent the measured parameter.
