Abstract: DRILL STRING SPLINED RESILIENT TUBULAR TELESCOPIC JOINT FOR BALANCED LOAD DRILLING OF DEEP HOLES Abstract of the Disclosure A drill string splined resilient tubular tele-scopic joint for balanced load deep well drilling comprises a double acting damper having a very low spring rate upon both extension and contraction from the zero deflection condition.  Preferably the spring means itself is a double acting compression spring means wherein the same spring means is compressed whether the joint is extended or con-tracted.  The damper has a like low spring rate over a considerable range of deflection, both upon extension and contraction of the joint, but a gradually then rapidly increased spring rate upon approaching the travel limits in each direction.  Stacks of spring rings are employed for the spring means, the rings being either shaped elastomer-metal sandwiches or, preferably, roller Belleville springs.  The spline and spring means are disposed in an annular chamber formed by mandrel and barrel members constituting the tele-scopic joint.  The spring rings make only such line contact with one of the telescoping member as is required for guid-ance therefrom, and no contact with the other member.  The chamber containing the spring means, and also containing the spline means, is filled with lubricant, the chamber being sealed with a pressure seal at its lower end and an inverted floating seal at its upper end.  Magnetic and electrical means are provided to check for the presence and condition of the lubricant.  To increase load capacity the spring means is made of a number of components acting in parallel.

Abstract: ABSTRACT            "A Pump, and an Apparatus incorporating such a Pump for infusing Liquid Medicine"    The pump has a chamber in which a piston reciprocates to pump a liquid.  The piston is moved by having secured thereto the armature of at least one electromagnet (preferably two).  The coil of the electromagnet is suitably external of the pump casing.  A control circuit pulses the electromagnet at a predetermined rate to provide a predetermined periodic output.     In a preferred form, the pump is mounted together with a liquid reservoir on a printed circuit board, and the unit is encapsulated for implantation in the human body to infuse a liquid medicine at a controlled rate into the bloodstream.

Abstract: TITLE:  SEAL RECEPTACLE ASSEMBLY     ABSTRACT OF THE INVENTION    A seal receptacle assembly is provided for affixation on a well conduit.  The seal receptacle assembly can be provided to permit telescopic contraction and expansion of the well conduit in response to heating, cooling, or pressurization of the well conduit.  The seal receptacle assembly includes an inner body sleeve having a lower end connected to the well tool or a conduit member, and an annular sealing element positioned over an outer cylindrical static sealing surface formed on the inner body sleeve.  An outer housing having one end connected to the well conduit telescopes over the upper portion of the inner body sleeve.  The housing has an inner cylindrical dynamic sealing surface for sealingly and slidably engaging the sealing element.          Means, such as a radially compressible retaining ring, are mounted in an outer groove formed on the inner body sleeve above the sealing element, or, alternatively, a collet is provided, for maintaining the sealing element on the static sealing surface during normal expansion and contraction of the seal receptacle assembly.  Upward movement of the outer housing causes the retain-ing ring, or collet, to expand outwardly into an inner groove in the housing and permit the housing to lift the sealing element off the static sealing surface.  The sealing element and the dynamic sealing surface can then be removed from the well in a single retrieval operation.

Abstract: STEAM TEMPERATURE CONTROL WITH OVERFIRE AIR FIRING ABSTRACT OF THE DISCLOSURE         Fuel and a first portion of combustion air are introduced into the furnace (10) of a fossil fuel-fired steam generator in a first zone (30) remote from the gas outlet (14) of the furnace.  A second portion of the combustion air, termed overfire air, is introduced into the furnace in a second zone (60) spaced from the first zone (30) intermediate the first zone and the gas outlet of the furnace.  The outlet temperature of the superheat steam conveyed through the superheater surface (24) is regulated by selectively directing the overfire air introduced into the furnace towards the gas outlet of the furnace to increase the superheat steam outlet temperature and selectively directing the overfire air introduced into the furnace away from the gas outlet of the furnace to decrease the steam superheat outlet temperature.          Further, the formation of oxides of nitrogen during combustion of the fuel in the furnace is controlled by selectively proportioning the air between the first and second portion so as to introduce into the first zone a quantity of air less than the stoichiometric amount required for the fuel introduced thereto and so as to introduce into the second zone a quantity of air sufficient to substantially complete combustion of the fuel within the furnace.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus is presented for demultiplexing two or more streams of data multiplexed in a phase shifted arrangement.  Demultiplexing is accomplished by multiplying the composite signal by an individual correlator signal for each data stream, each correlator signal being mutually orthogonal with the other correlator signals.  In the data recording art, the invention is particularly useful for reading several data tracks simultaneously, thereby reducing the need for maintaining track spacing.  In the data transmission art, the invention is useful for demultiplexing a composite signal, consisting of two or more data streams.

Abstract: Abstract The invention relates to a new process for the preparation of apovincaminic acid esters.  More particularly, the invention concerns a process for preparing racemic and optically active vincaminic acid esters of the formula (I) (I)   in which R1 and R2 independently stand for alkyl having from one to 6 carbon atoms, and 14-epimers thereof.    According to the invention an octahydroindolo-[2,3-alquinolizine-oxime ester of the formula (II) (II)   in which R1 and R2 have the same meaning as defined above, is reacted with an aqueous solution of sulphurous acid or a salt thereof at a temperature of 80 to 110°C and the 14-epimeric mixture obtained is epimerized or separated in a known manner and if desired, the racemic vincaminic acid esters are resolved.    The valuable, pharmaceutically active compounds of the formula (I) can be prepared according to the invention in a considerably improved yield and the undesired side reactions can be suppressed and/or the by-products can easily be converted into other pharmaceutically active materials.

Abstract: ASTRACT OF THE DISCLOSURE   A device for centering spectacle lenses and for fastening a holding part on the lenses.  The device in-cludes a mounting base, a guide or column sleeve arranged vertically thereon, as well as a casing which is rotat-able and displaceable in height, and to which a swivel arm which supports the holding part is connected.  The object of the present invention is to make it possible, with simple means and without great structural expense and without taking a lot of time and effort, to be able to lower the holding part accurately vertically along a prescribed straight line onto the spectacle lens, so that the holding part maintains a desired precise posi-tion on the spectacle lens, and with the aid of which the lens can be inserted in an edge grinding machine.          To realize this, the device is embodied such that a torque is exerted upon the casing during longitudinal movement relative to the column sleeve.  As a result of this torque, a guide edge of the casing is held free of play in sliding engagement against a guide part or pin of the column sleeve.
