Abstract: Abstract A rigid stabilizer sleeve having outwardly extending ribs is slideably received over a drill collar.  A pair of internal clamping rings are slideably received through each end of the rigid main sleeve.  As a threaded end cap is threaded into the rigid main sleeve, the end cap forces one ring of the pair against the other thereby producing a clamping effect whereby the stabilizer can be clamped at any desired position on the drill collar.  An outer ring of the pair of rings has a groove and a rib disposed on its interior cylindrical surface; the portion of the end cap received by the outer ring has a rib and a groove disposed upon its outer cylindrical surface. As the end cap receives the outer ring, the rib and the groove of the end cap interlock with the groove and the rib respectively of the outer ring whereby when the end cap is threadedly removed from the rigid main sleeve, the outer ring follows the end cap and is disengaged from the inner ring, thereby unclamping the pair of rings from the drill collar.

Abstract: BLOOD OXYGENATOR WITH INTEGRAL HEAT EXCHANGER      Abstract of the Disclosure A blood oxygenator includes a heat exchanger wherein heat transfer fluid flows through an aluminum tube having an integral, substantially continuous hollow helical rib along its length providing a substantially continuous helical flute.  The tube is positioned within a chamber connected in an extracorporeal blood circuit such that the blood is caused to flow over the anodized exterior surface of the helically ribbed tube.  In the preferred embodiment, the blood flows through a plurality of continuous, restricted area flow paths offering substantially uniform flow impedance to the blood, these restricted flow paths being provided by forming the helically ribbed tube in a helical configuration mounted between an inner cylindrical column and an outer cylindrical shell such that the blood is caused to flow through the plural paths of restricted cross-sectional area provided by the helical flute.  In one embodiment, the heat exchanger tube and blood chamber are formed as an independent unit adapted for use in the desired location of an extracorporeal blood circuit.  In the other embodiments, the heat exchanger is formed integral with a blood oxygenator in which oxygen is absorbed into the blood and carbon dioxide is released therefrom.

Abstract: PARAGRAPH INDENT                        Abstract of the Invention Described herein is a feature and the electronics and logic necessary to implement a paragraph indent feature on an electronic typewriter which is improved and more advantageous than previous routines which accomplished similar results. Paragraph Indent is beneficial to the operator in that it automatically positions the printing carrier at an indented level for setting off typed material so that the left edge of the indented material does not extend to the normal left margin.  The typewriter under electronic control stores in memory, upon an appropriate command, a temporary left margin to which the carrier will return when the typewriter is operating under the paragraph indent mode.  The operator may enter the Paragraph Indent mode from the keyboard by keying an alternate or code together with a tabulation or tab code.  This causes the electronics to control the typewriter so as to move the print point to the next tab stop and thereafter until countercommanded will return the carrier to that indented line position on all subsequent carrier returns.

Abstract: WIPER DRIVE ASSEMBLY                        ABSTRACT      A wiper drive assembly (20) disclosed is particularly adaptable for use with angularly skewed vision blockes (22) of an armored car.  A hollow guide (28) of the assembly includes elongated first and second guide portions (30,32) that are adapted to extend along-side the vision blocks and which receive respective first and second wiper supports (70,104).  Each wiper support has an extension that projects through a slot in the associated guide portion so as to allow mounting of the arm of an associated wiper (24,26).  One of the wiper supports has its extension provided with a slidable connection (86) to a continuous drive loop which is preferably in the form of a chain (34) received by a pair of sprocket type sheaves (36,38).  Driving of one of the sheaves moves the chain so as to drive the first wiper support (70) in a reciprocal manner.  An elongated connector of the drive assembly is preferably embodied by a wire (118) that extends between the first and second wiper supports within the guide portions in a guided relationship so as to move the second wiper support (104) along with the first wiper support in a reciprocal manner.

Abstract: ABSTRACT OF THE DISCLOSURE         In a control panel assembly for use in a microwave oven or other cooking appliance, there is described an assembly wherein all of the various circuit elements employed, including semiconductor chips, are mounted on the opposite side of a printed circuit board to various sources of heat within the oven.          Known assemblies expose the circuit elements, some of which are heat sensitive, to heat radiating from within the oven and are therefore prone to malfunction.  In this invention, a printed circuit board forms the back surface of the control assembly.          The various circuit elements utilized are all mounted on the surface of the circuit board facing inwardly of the assembly whereas the connections to the board are all made on the outward surface of the board which faces towards the heat sources.  A further advantage of such a construction is that the outward or second surface of the circuit board remains substantially flat and is therefore easily connectable to devices which can test the operating condition of the assembly.

Abstract: ABSTRACT     The invention refers to a system for measuring the heat transmission coefficient k for a wall portion separating medias having different temperatures, making use of temperature sensing means which are connected to an evaluation device.  Such systems are commonly used for determining the insulation of house walls, but the priorly known systems are complicated as well as expensive The purpose of the invention is to provide a handy, simple and unexpensive system for measuring the heat transmission in whole wall areas, windows and doors.  This purpose is, in a preferred embodiment of the invention, realized by the provision of a first thermocouple (7) for measuring the inner or room tempera-ture ti, mounted at a housing for the system, and a second thermocouple (7) for measuring the inner wall temperature tv, mounted at the end of a probe for contacting the inner wall, the two thermocouples being interconnected to provide a signal proportional to the temperature difference ti-tv to an opera-tional amplifier (1).  The amplifier constitutes said evalua-tion device and has its output connected to an indicating instrument (3).  There are also means for indicating the inner temperature ti as well as the outer temperature tu to the user. A feed-back path is connected between the output and the input of the amplifier (1) and includes a manually adjustable poten-tiometer (5) for providing an amplification of said signal, which is inversely proportional to ti-tu, as determined by the setting of the potentiometer to the temperature difference ti-tu.  Thereby, the output signal from the amplifier will be A(ti-tv)/(ti-tu), equivalent with the heat transmission coefficient k, where A is a constant chosen to express said output signal as the numerical k value on the indicating instrument.

Abstract: PROCESS                    ABSTRACT n-valeraldehyde is produced by hydroformylation of butene-l in the presence of one or more of cis- and trans-butene-2 and iso-butylene using a rhodium complex catalyst such as HRh(CO)PPh3)3.  Reaction conditions include use of at least about 100 moles of free triorganophosphine per gram atom of rhodium, a temperature of about 80°C to about 130°C, a total pressure of not more than about 50 kg/cm2 absolute, a partial pressure of carbon monoxide of not more than about 1.5 kg/cm  absolute, and a partial pressure of hydrogen of from about 1.5 to about 7.5 kg/cm  absolute. An n-/iso-ratio of 20:1 and a conversion efficiency of butene-1 to n-valeraldehyde of over 85% are possible under these conditions with essentially no resin formation despite the presence of iso-butylene.  The n-/iso-valeraldehyde mixture can be aldolized and reduced without intermediate purification to give a commercially acceptable C10-plasticiser alcohol.
