Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed is a combustion chamber of an internal combustion engine.  A first raised portion having a flat bottom is formed on the inner wall of the cylinder head so that a first flat squish area is formed between the flat bottom of the first raised portion and the flat peripheral portion of the top face of the piston.  A second raised portion is formed on the top face of the piston at a posi-tion opposite to the first raised portion with respect to the axis of the piston and has a spherical rear wall so that a second spherical shell shape squish area is formed between the inner wall of the cylinder head and the rear wall of the first raised portion.  The first squish flow spouted out from the first squish area moves forward along the top face of the piston.  The second squish flow spouted from the second squish area moves forward in the upper interior of the combustion chamber in the direction opposite to the spouting direction of the first squish flow.  The first and second squish flows cooperate with each other to create a strong swirl motion rotating about a horizontal axis in the combustion chamber.

Abstract: TEMPERATURE PROBE ASSEMBLY FOR        GAS TURBINE ENGINE            ABSTRACT OF THE DISCLOSURE A self-contained temperature probe assembly for sensing the disc cavity temperature of a gas turbine engine is shown.  The assembly includes a thermocouple probe comp-rising an upper tube and a lower tube housing the probe leads.  The lower tube extends from the cylinder housing through the blade ring to guide the probe tip through a hollow vane to adjacent a rotor disc and includes a tapered portion for sealing engagement with a tapered aperture in the blade ring as biased by a coil spring.  The upper tube extends outwardly from the turbine cylinder to the probe head.  The adjacent ends of the two tubes are retained in a standard flange in predetermined spaced relation against outward withdrawal and the lead wires are coiled within the space to maintain a slack condition to prevent transmission of vibration of the lead wires into the probe head and also prevent the rather fragile wires from supporting any weight of the probe during shipping or installation of the probe to the turbine.

Abstract: ABSTRACT OF THE DISCLOSURE            An air pumping and scrubbing apparatus which is suitable for use in spray paint booths is described.  This apparatus uses liquid sprays directed into a conduit to cause an air pumping action to inject air into the conduit and discharge to atmosphere using water pressure to move the air so as to avoid the necessity for any moving parts or electrical connections in and around the air stream.  The liquid sprays impinge on mist eliminator strips and are recovered along with foreign material from the air while the air is exhausted downstream of the strips.  A novel transfer plate arrangement is provided between the strips and a sump to minimize foreign material buildup on structural surfaces while allowing stratification in the sump; and novel baffle means are provided to cause a controlled air blowback across the sump to facilitate collection of the floating material therein.

Abstract: NILS JOHNNES BAECKLUND A method and apparatus for measuring the content or quantity of a given element by means of X-ray-radiation A method and apparatus for measuring the content of an element by means of X-ray-radiation. Electrons from the cathode of a low-power X-ray tube are directed onto one side of the anode of said tube, said anode comprising a thin layer of anode material on a beryllium plate. The electrons excite primary X-ray-radiation in the anode material, including the characteristic X-ray lines. The radiation passes out through the opposite side of the anode as transmission radiation and is directed onto the element to be measured, whereupon fluorescense occurs, said fluorescense being caused by the characteristic lines. The fluorescense lines of the substance are then isolated by means of a balanced filter. (Fig. 1)

Abstract: INFUSION CONTROLLING APPARATUS AND METHOD   Abstract Portable electronic medical apparatus for controlling the flow rate of a fluid for medically treating a patient may receive flow rate information representing sequences of up to 20 flow rates and their durations from an individual and from an electronic data processor, and operate continuously without the presence of an operator for in the range of 40 hours.  Upon the incorporation of an infusion pump into the apparatus, the desired regimen of treatment may be accomplished; and through a keyboard input for the apparatus, an operator may in certain respects modify a regimen which is being carried out.  The apparatus may be used in a method of treatment including:  coupling the apparatus to the processor; providing the apparatus with the flow rate information; decoupling the apparatus and processor; transporting the apparatus to the patient; coupling the apparatus to a supply of the fluid and regulating the flow rate of the fluid according to the information.  It may be similarly used in a method including the providing of an electrical signal representative of a sequence of, e.g., at least 8 discrete fluid flow rates and their durations. The signal may then, if desired, be independent of changes in the condition of the patient during such providing.  Safety features in the apparatus include:  a frequency detector for monitoring the frequency of a clocking signal for the apparatus; the selec-tive testing of output signals of the apparatus, the portable power supply for the apparatus and the frequency detector against stored predetermined standards; and the provision of warning signals to an operator to indicate divergences from such standards. Additionally, fail safe signals for the apparatus are coupled to relay circuitry to interrupt the output of the apparatus if a central processing unit for the apparatus enters undesired modes of operation.

Abstract: METHOD FOR PRODUCING UNIFORM PARALLEL   ALIGNMENT IN LIQUID CRYSTAL CELLS            Abstract of the Disclosure A method of treating the surface of substrates used in liquid crystal display cells so that the surface forces the liquid crystal director to be aligned uniformly over the entire surface and parallel to the substrate surface.  The method includes the step of forming a plasma  beam containing oxygen free-radicals, inert gas free-radicals such as argon, neon and helium, and free radicals of a compound containing the element to be deposited, for example, silicon, tin, indium, etc.  Preferably a volatile organo-silicon or an organo-tin compound is used to supply the silicon or tin.  The plasma beam is then directed at the substrate surface at an angle, preferably of about 30°, for a time sufficient to deposit a film.  The liquid crystal display cell utilizing a substrate formed in this manner has a high contrast ratio as well as a sharp threshold in its electro-optical characteristics.
