Abstract: INTERNAL COMBUSTION ENGINE          Abstract An internal combustion engine (10) comprising an engine frame (12) having a drive shaft (20) rotatably mounted therein and extending outwardly therefrom.  A pair of cylinder sleeves (40, 40') are mounted on the engine frame (12) and have their inner ends positioned within the interior of the frame and their outer ends positioned outwardly thereof.  A cylinder head (60, 60') is secured to the outer end of each of the sleeves and is separated thereby by means of a heat insulative gasket (70).  Each of the cylinder heads (60, 60') has a dome-shaped  chamber (62, 62') formed therein which is in communication with a source of combustible fuel. An air inlet conduit (94) is mounted on one end of the engine frame and is in communication with a source of air under pressure such as a blower, supercharger or the like. The air inlet conduit is in communication with an air passageway (100) formed in the engine frame (16) which is in communication with air inlet openings (52, 52') formed in the cylinder sleeves (40, 40').  The cylinder sleeves (40, 40') are provided with exhaust openings (54, 54') formed therein which communicate with an air exhaust passageway (102) formed in the engine frame (16).   The exhaust passageway (102) is connected to exhaust conduit (106) or pipe extending from the engine frame (16).  A piston (72, 72') is slidably mounted in each of the sleeves (40, 40') and has a dome-shaped head portion (76, 76') which is adapted to be received by the dome-shaped chamber (62, 62') in the cylinder head (60, 60') when the piston is in its top position.  In the top position, the small "air space" (118) is present between the walls or sides (78, 78') of the piston head (76, 76') and the walls or sides of the sleeves (64, 64'). The "air space" (118) serves as a means for retarding the absorption of heat into the sides of the piston head (76, 76') and the sides of the cylinder sleeve (40, 40').  In the down position, the "air space" (118) also serves to spread the cooling air into a thin, wide sheet for more efficient cooling of the cylinder head (60, 60') and sleeves (40, 40').  Optional air deflecting fins (84, 86, 84', 86') may be employed on the piston head (76, 76').  The rings (82, 82') of the piston (72, 72') are conventionally lubricated and slide upon the interior wall (52, 52') of the cylinder sleeve (40, 40').  Each of the pistons (72, 72') has a roller (88, 88') mounted on  the skirt portion (74, 74') thereof which rolls upon a cam (32) mounted on a rotor plate (30) which is secured to the drive shaft (20) for rotation therewith. A return roller (92, 92') is also operatively mounted on the skirt portion (74, 74') of the piston (72, 72') for engagement with a return cam (36) which is mounted on the drive shaft (30) for rotation therewith.

Abstract: ABSTRACT OF THE DISCLOSURE A track aligning device for monitoring the curvature of a track and adjusting the track successively to correct the curvature incorporates two taut wires mounted on a car or cars running on the track, the wires each defining two chords each extending between a pair of spaced points located on the track center line.  Preferably the cords overlap.  Each chord operates as a reference line which cooperates with a respective measuring device.  A first measuring device located nearer the rearward point of the first chord derives a voltage which is sampled at equal intervals, say 2 meters, as the aligning device passes along the track.  The voltages are summed and averaged electrically and a voltage equivalent to the mean displacement of the track from the first chord is obtained.  The second measuring device is located nearer the rearward point of the second chord and derives a voltage equivalent to the actual displacement at that position of the track with respect to the second chord.  This voltage is compared electrically with the mean voltage and an error voltage is derived and used to operate a servo-assisted aligning mechanism to adjust the track to the left or right as necessary.  In a pre-ferred embodiment the device can also adjust the superelevation of the track to meet the necessary value as computed on the basis of track curvature and designed train speed.

Abstract: Abstract of the Disclosure A microminiature palladium oxide gas detector and its method of manufacture.  The detector  comprises an extremely small coil of extremely fine wire such as platinum which is retained, sealed and insulated with an amorphous ceramic binder.  The detector further comprises a catalyst applied to its exterior surface.  The detector is manu-factured by winding the wire about a mandrel which is desirably molybdenum.  The coil is then coated with the binder composition which preferably comprises reduced chromic and phosphoric acids.  The binder is then cured to retain the coil and the mandrel is removed by etching or oxidation.  The catalyst is then applied which is preferably palladium nitrate in a weakly acidic hydrolyzed solution which has been adjusted to a pH of about 3 with tertiary octyl amine.  The catalyst is then dehydrated and calcined desirably using an automatic electronic pulse controlled machine to precisely adjust and control processing temperatures and times.  When hydrolyzed palladium oxide is used as the catalyst, the processing temperature never reaches the point where the oxide becomes reduced to the metal.

Abstract: ABSTRACT OF THE DISCLOSURE         An internal combustion engine includes a flywheel-mounted permanent magnet alternator connected to a converter having gated switches operating in an on-off mode to provide a regulated voltage to a battery and electrical load power. A voltage sensing unit which is responsive to battery volt-age is connected to a gate current transistor for continu-ously supplying gate current and turning the switches fully on and off for producing a regulated output.  The sensing unit includes a minimum pulse width circuit to insure a minimum turn-on signal when power is demanded.  Second gates switches function as overvoltage protectors of the crowbar shunt type.  An overvoltage detector is connected to the converter output and to a second gate current transistor for supplying gate current and turning on the second gated switch means in response to a major voltage deviation. Supression circuits reduce RFI and required withstand voltages of the switch means and the first gate current transistor.

Abstract: ABSTRACT OF THE DISCLOSURE:         A method and apparatus for manufacturing lined latex girdles in which one end of a fabric sheath which will form the liner of a latex girdle is sewn or otherwise fastened together and slipped over an annular rectangural frame, with the closed end of the bag disposed in the middle of the annular rectangular frame.  A flat form, with substantially curved sides, is first covered with a latex film, and while tacky, is pushed through the frame, engaging the fabric liner.  As the form is pushed through the frame, the liner slides over the frame, and contacts the sides-of the form.  When the form has been pushed complete-ly through the frame, the liner will be supported on the form, which may then be easily withdrawn for final processing.        Close tolerances between the dimensions of the form and the frame assist in providing quality control with respect to the inter-penetration of the fabric liner and the latex film.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and an apparatus for pneumatic conveying of flowable materials are disclosed.  Flowable material is entrained in an air stream and conveyed into the con-tainer of a container-type scale.  When the scale senses that the weight of admitted material is approaching the preset desired weight it causes a reduction in the ma-terial flow.  This ligher flow then continues until the preset weight is reached, at which time the admission of material into the air stream is terminated.  The air stream, however, continues to flow until all or substan-tially all material still present in the conduit at this time has been conveyed into the container to be weighed along with the remainder of the container contents.

Abstract: IMPROVED ENDLESS RIBBON CARTRIDGE    Abstract A freely rotatable spool having an endless loop of printer ribbon wound around it is disclosed. The ribbon is withdrawn from the inner periphery of the coil and is simultaneously wound onto the outer periphery of the coil in a known manner. The freely rotatable spool is driven by the forces applied through pulling the ribbon off the inner periphery.  Ribbon pulling is performed by an external set of feed rollers or similar mech-anism.  Difficulties encountered with the use of fabric ribbons in endless reel configurations are eliminated in the present invention by an improvement in the form of a polygonally shaped flange on the upper side of the freely rotatable spool on which the ribbon is wound.  The flat sides on the polygonal flange have an optimum length which is defined in relationship to the width of the ribbon and the cosine of the angle at which the ribbon is withdrawn from the spool.  An undercut dimension is provided on the spool so that the inner peri-phery of the ribbon is not in too great a contact with the hub or central core of the spool.  A smooth ribbon flow from the vertical plane on the inner periphery of the coil to the horizontal plane as the ribbon is pulled from the center of the coil and out through the cassette is obtained.

Abstract: Abstract of the Invention An assembly for separating particulate matter from an influent carrier comprises a perforated plate for separating an inner compartment from an outer compart-ment, and for transferring the influent between the inner and outer compartment with a minimum amount of a convective momentum that is associated with disturbing the settling matter.  In practicing the process, suspensions are introduced into the assembly at the inner compartment.  An agitator subassembly, within the inner compartment, sequentially fast mixes and slow mixes the influent to respectively insure mixing of the influent with additives and to promote agglomeration of the suspensions.  Flow paths in the perforated plate function to cancel all velocity components of the momentum, except for vertical downward acting velocity components, thereby maximizing the rate of settlementa-tion.

Abstract: ABSTRACT OF THE DISCLOSURE       A memory subsystem includes a memory board comprising of a number of memory chips positioned at a corresponding number of physical row locations.  The memory chips are one of two types selected to provide a predetermined memory capacity.  The board further includes a number of decoder circuits connected to generate a corresponding number of sets of chip select signals in response to address signals applied thereto.  These signals are applied through corresponding sets of logic circuits for application to the memory chips of each row.  Additionally, logic gating circuits logically combine predetermined chip select signals for generating additional chip select signals.  These additional chip select signals are applied through switches, the outputs of which are applied to predetermined ones of the sets of logic circuits.  When the switches are positioned in a predetermined manner, the additional chip select signals are directed to only pre-determined ones of the physical row locations via the sets of logic circuits.  In this case, only the predetermined row locations are populated with one of the types of memory chips of much larger capacity.  This provides the same predetermined memory capacity that is provided when all of the physical row locations are populated with the other type of memory chips of smaller capacity making possible reductions in manufacturing costs.
