Abstract: ABSTRACT OF THE DISCLOSURE                      CONVERSION PROCESS    Process for the production of synthesis gas and higher hydrocarbons in which a saturated hydrocarbon and an oxygen containing gas having a ratio of hydrocarbon to oxygen of greater than the stoichiometric ratio for complete combustion are introduced into a bed of an inert particulate material.  The upward flow rate of the hydrocarbon/oxygen containing gas stream is sufficient to fluidise or to produce a spouting action of the bed material? whereby the particulate material is thrown up above the bed surface and subsequently falls back into the bed.  The hydrocarbon and oxygen containing gas are ignited and reacted together, and the products of the reaction withdrawn.

Abstract: ABSTRACT         A microwave antenna feed network dispenses with the conventional phase shifters.  Instead, the required phase rela-tionships between the different individual antenna components is achieved by means of a new device, known as a phase slope equal-izer, placed in each feed line.  This device is formed of a section of wavequide containing one or more resonant circuit elements.  Each element comprises, for example, a pair of spaced inductive posts and capacitive tuning screw, or an inductive iris and a capacitive tuning screw, or a resonant slot.  The phase slope equalizer exhibits a substantially constant slope phase shift/frequency response curve extending from a positive phase shift through zero phase shift at midband to a negative phase shift.  The device is simpler and smaller than the conventional phase shifter and fewer are required thereby reducing costs.

Abstract: ABSTRACT:          Method and device for manufacturing a connector part for an optical connector.         A spherical lens (5) is fixed to the front end of a tubular housing (1) and an end part of a light-conducting fibre (9) is fixed with its first end face (11) in the focal plane of the lens. The line through the centre (13) of the lens (5) and the middle of the first end face (11) is the optical axis (17). The housing (1) with the lens (5) is placed against a seat (25), which is formed as a cavity with a rotationally symme-trical surface, on whose axis of rotation (27) a light detector (31) is mounted, which is designed to determine deviations between the direction of a light beam coming from the lens and the direction of the axis of rotation. Near the second end face (45) of the fibre (9) light is injected into the fibre, and the rear end of the housing is displaced in two directions (x, y) perpendicular to the optical axis, until the light beam emerging from the lens (5) coincides with the axis of rotation (27). The lens (5) with the seating (25) thereby functions as a ball hinge. The outer surface of the housing (1) is now finish-machined with a tool (49) that rotates around the axis of rotation (27).

Abstract: ABSTRACT     A system is disclosed for determining the positions of a set of points on a vehicle body or frame and comparing those points to a set of reference points provided by the vehicle manufacturer or other source.  The system includes a data acquisition apparatus comprised of emitters, receivers, and microprocessor control means.  The emitters are mounted at various predetermined positions on the vehicle body or frame and are triggered in an optimal fashion by the microprocessors.  Triggering generates a single acoustic burst signal from an emitter.  An array of microphones acts as the receiver.  After generation of the signal, the microprocessor initializes an external clock which measures the travel time of the signal from the emitter to the receivers.  By repeating this process a number of times, data is acquired which yields the three-dimensional coordinates of a given point when processed by a microprocessor.  Microprocessors further convert this data into a form that can be used by the overall system to determine the positions of all points measured on the vehicle body or frame.  The data is transmitted to an operator display unit where it is plotted graphically.  Reference data is inputted into the operator display unit via an optical decoder.  This data and a comparison of the two sets of data is displayed.  Based on the data comparison, the operator can then determine whether and to what extent repair work or further maintenance work on the automobile body, frame or wheels is necessary.
