Abstract: ABSTRACT: Apparatus for reading an optically coded disc-shaped record carrier.     The invention relates to an apparatus for reading a dish-shaped record carrier with a spiral information track in which an optically readable digitally coded in-formation signal is recorded with a spatial bit frequency which is independent of the radius of the track turn. The scanning speed of the information track is selected to be a factor n higher than the scanning speed normally employed for the reproduction for the recorded information. By means of a memory device information blocks being read and comprising a fixed number of data bits are time-expanded to restore the customary time relationship. A control unit determines the read-in cycles of the memory device for the storage of the information blocks being read and, via the radial positioning system for the read spot, it determines the scanning pattern of the record carrier so that the ultimately recorded information blocks are reproduced in the same sequence and at the desired rate.

Abstract: CATALYTIC CONVERSION OF OLEFINS TO HIGHER HYDROCARBONS    Abstract An improved continuous process for converting lower olefinic hydrocarbon feedstock to C5+ liquid hydrocarbons by contacting vapor phase olefinic feedstream with acid zeolite catalyst in the presence of recycled diluent stream rich in C3-C4 hydrocarbons in an enclosed reactor at elevated temperature and pressure.  The improved technique comprises a system for cooling reactor effluent to recover a heavier hydrocarbon stream containing a mixture of C3-C4 hydrocarbons and C5+ hydrocarbons and debutanizing the heavier hydrocarbons below reactor pressure to obtain a C5+ product stream and a condensed C3-C4 hydrocarbon stream.  Operating efficiencies are realized in the heat exchange system by reboiling the debutanized C5+ hydrocarbon product stream by heat exchange with hot reactor effluent, and by recycling and combining at least a portion of the condensed C3-C4 hydrocarbon stream to dilute the liquid olefin hydrocarbon feedstock.  By increasing pressure on the liquid olefinic hydrocarbon feedstock and liquid recycle stream to at least the elevated reactor pressure in the liquid state prior to vaporization, energy is conserved.  An apparatus arrangement for conducting such a process is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention discloses a partially consumable spacer chill or welding ring which includes a generally cylindrical non-consumable base metal ring having an outside diameter of such a size as to snugly fit the inside diameter of the pipe end to be welded.  A circular consumable filler metal spacer ring is medially attached to the outer periphery of the base metal ring and extends peripherally radially outwardly to function as a spacing device between adjacent ends of two lengths of pipe to be joined.  The consumable spacer ring may be affixed to the base metal ring in a plurality of circularly offset locations by spot welding or may be press-fitted in an alignment groove in the base ring.  The consumable spacer ring becomes filler metal during welding.

Abstract: Abstract of the Disclosure A dielectric resonator consists of a body of dielectric material mounted in close proximity to a microstrip line with which a high frequency electrical signal is coupled.  The resonance frequency of the resonator is altered and adjusted by varying the level of a d.c. bias voltage applied to two varactor diodes which form part of an inductive closed circuit mounted adjacent to the end of the body which is remote from the microstrip line.  By varying the bias level, the resulting change in inductance causes the resonance frequency to alter in a controlled manner over an appreciable frequency range.

Abstract: METHOD AND APPARATUS FOR MEASURING         FLOW IN A PIPE OR CONDUIT            Abstract of the Disclosure This  method  and  apparatus  is directed  to measuring flow velocity of a flowing solid or fluid in a pipe.   In the preferred and illustrated embodiment,  a single magnet is utilized to impress a magnetic field on the flow, the field having a gradient.  A concentrically arranged detection coil is positioned in the field and is connected with a nuclear magnetic resonance (NMR) or electron magnetic resonance (EMR) detection apparatus.  A segment of the material moves through the magnetic field. The frequency of a the magnetic resonance signal emitted by the nuclei or electron changes proportionate to field intensity.  In a fixed gradient, the time rate of change of the emitted NMR or EMR frequency signal  is a linear function of flow velocity.   This apparatus provides a measure of flow velocity by interrogating with pulses thereby obtaining a  frequency dependent  signal.   The approach has the advantage of utilization of a single coil and yields measurements which are independent of density or filling factor and also independent of elemental couplings identified as T1 and T2.

Abstract: VARIABLE PRESSURE CONTROL                         Abstract A variable pressure control for controlling displacement of a variable displacement over-center pump utilizes a pair of remotely variable pressure limiter three-way valves which are associated one with each of a pair of servo cylinders operably connected to a swash plate of the pump and acting in opposition for positioning of the swash plate.  The pressure limiter valves each control the communication of a servo cylin-der with either system pressure or drain and are re-motely operable to set a displacement of the pump and limit the pressure of the fluid delivered by the pump. This structure enables setting of pump displacement without the use of a displacement control valve associated with the servo cylinders.

Abstract: INERTIAL REFERENCE SYSTEM                  Abstract of the Disclosure An inertial sensor assembly (ISA) includes a cluster of three ring laser gyros, each gyro producing an output signal having a pulse repetition rate representative of the rate of angular deviation of the ISA about one of three coordinate axes X, Y, and Z. The ring laser gyros are asynchronously dithered at a relatively constant rate. The ISA also includes a triad of three accelero-meters, with each accelerometer producing an output signal representative of the rate of velocity deviation of the ISA along one of the X, Y, and Z coordinate axes. A first processor, P1, accumulates the pulses produced by each ring laser gyro over its dither period. The resultant counts are stored in registers for subsequent sampling by the P1 processor at a periodic sampling rate which is greater than the dither rate. The P1 processor then synchronizes each sampled pulse count to a common sampling interval, thereby eliminating errors otherwise caused by using positional data values taken at different times. The P1 processor also compensates the ring laser gyro and accelerometer-produced signals at the sensor and the system level for effects such as temperature, bias offsets, scale factor and misalignment by the use of compensating coefficients stored in electrically erasable, programmable read-only memory. The processed data from the P1 processor are passed to a P2 processor which performs navigational computations to thereby produce computed positional information.

A method is provided for the preparation of the novel catalyst and comprises forming an acid salt derivative of the transition metal complex and mixing it together with an anion-exchange resin.  A process wherein the novel catalyst is added to a strained cyclic non-con-jugated carbon containing compound resulting in the release of heat energy through the conversion of the non-conjugated carbon containing compound to its conjugated form.  A process and sealed container means wherein the non-conjugated carbon containing compound and the catalyst are in compartments and are separated until heat energy is required.  The means of separation is then broken and the non-conjugated carbon containing compound is converted to the conjugated form with the release of heat energy.  A process and apparatus wherein the conjugated carbon con-taining compound is exposed to radiant energy and is con-verted to the non-conjugated form.  The non-conjugated form is then combined with the catalyst described hereinabove, converting the non-conjugated form to the conjugated form and resulting in the release of heat energy which is collected.
