Abstract: ABSTRACT              DOUBLE FABRIC, RETRACTABLE            SELF-ERECTING WING FOR MISSILE     A retractable, self-erecting wing for a low speed missile, having a double walled fabric body held in extended position by spring loaded struts, the fabric enclosing an air pocket which acts as a damper to prevent the wing from fluttering under certain aerodynamic conditions.          The wing is extended by a hinged strut structure and folds into a very small space adjacent the outer wall of the missile body.  The structure enables a large area wing to be stowed in a minimum of space so that the maximum internal volume is available for payload.  In stowed condition the wing is completely enclosed in the body for minimum drag during any high speed portion of the missile flight, multiple wings being released when required by a simple mechanism.

Abstract: LEVERLESS PRESSURE TRANSDUCER                 ABSTRACT OF THE DISCLOSURE    A temperature or pressure sensor that produces a hydraulic pressure signal proportional to temperature or pressure.  The sensor or transducer utilizes a plurality of bellows acting on a valve nozzle plate so that the temperature signal which is a gas pressure moves the nozzle plate to control the flow through the nozzle as a function of temperature thus producing a metered pressure proportional to temperature.  The bellows are arranged to minimize temperature error in the transducer.  Where the temperature sensed is engine inlet temperature the metered pressure may be used to control the fuel through the turbine engine as a function of the engine inlet temperature.          This same device is equally utilized in measuring a pressure, such as compressor discharge pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           A container has a closure which consists a lid with an annular flange separated by an annular failure zone.  When the container is originally sealed the closure is inserted into an opening formed in the container and the flange is permanently connected to a flanged top surface of the container which surrounds the opening.  The lid is dished inwardly from the failure zone into the opening surface.  The lid may be broken open and torn along the length of the failure zone by a locally applied force. The application of force inwards will as a rule displace the dished lid inwardly within the opening to stop against a ledge provided in the container.  The lid adopts a similar position in a re-sealed container.  Gripping devices, preferably in the form of stiffening ribs, make it easier to remove the lid from the position just mentioned.

Abstract: ABSTRACT OF THE DISCLOSURE     This specification discloses an apparatus and method for controlling the air fuel ratio in an internal combustion engine.  The instantaneous air fuel ratio is compared with the inverse of a prior air fuel ratio to determine if an adjustment is necessary.  If the inverted prior state of the air fuel ratio is the same as the present state, no change to the air fuel ratio will occur.  If the inverted prior state is not the same as the present state, a control correction in the air fuel ratio will occur.  The system will not change control voltage if the predicted stated and the actual state of the air fuel ratio agree.

Abstract: ABSTRACT          An apparatus and process for transporting, orienting and printing indicia upon materials which have dissimilar ends, like capsules, in a predetermined orientation and position. The apparatus includes three rotatable drums (28, 34, 150) in tangential arrangement.  The first two drums (28, 34) each include a plurality of peripherally spaced pockets (40, 42) sized and shaped to receive and carry individual capsules (20).  Means (58,58') are provided for each drum to orient certain preselected capsules from a radial to a longitudinal position with a selected end trailing.  The so-oriented capsules are then delivered to the third drum (150) for further processing, like printing, such as spin-printing (178).  Means (154) are provided to receive the longitudinally oriented capsules from the second drum (34) in a longitudinal orientation, and to rotate the capsules from the longitudinal to a transverse orientation, whereupon selected indicia may be applied to the capsules.  The third drum (150) including the printing means (178) is also capable of use alone, separate from the first two drums, to apply indicia to a variety of materials or bodies having both similar and dissimilar ends, e.g. capsules, pellets or tablets.  Printing is preferably accomplished using a spin printing apparatus which, unlike spin printing apparatus of the prior art, operates upon materials traversing a curving path.

Abstract: METHOD AND APPARATUS FOR ENHANCING             THE OUTPUT OF AN RMS CONVERTER                 Abstract of the Disclosure A method and apparatus for enhancing the output of a log-antilog type root-mean-square (RMS) converter by correcting the RMS converter output for nonlinearities in the AC/DC transfer characteristic of the converter are disclosed. First, preselected positive and negative DC voltages near the upper and lower ends of the range of the RMS converter are applied to the RMS converter and the output of the converter is measured by a voltage measuring instrument for each applied voltage. The applied and measured voltage values are used to determine the positive and negative gain (G) and offset voltage (V0)characteristics of the RMS converter. The characteristic information is used to correct (e.g., enhance) the output of the RMS converter when AC voltages fallingwithin the range of the converter are later applied. The same procedure is followed for each range of the RMS converter, if the RMS converter has multiple ranges. Further enhancement is provided by correcting for gain errors resulting from crest factor variations. Crest factor variation enhancement is provided by applying preselected square waves to the converter and measuring the output of the converter. The measured output voltages are utilized to determine the positive and negative gain crest factor correction constants, which are used to correct the positive and negative gain characteristics of the RMS converter.

Abstract: ABSTRACT Two refractory plates are adapted to constitute the stationary base plate and movable sliding plate of a sliding gate valve for pouring metal melts, particularly non-ferrous melts such as aluminium.  The base plate is made of soft, self-lubricating material having a low wettability, a high thermal conductivity and a low cold compression strength.  The sliding plate is made of a hard, low porosity material with a low thermal conductivity and a high cold compression strength.  The self-lubrication provides a good seal between the sliding surfaces of the plates thus inhibiting penetration of the melt between the sliding surfaces and the differential in thermal conductivities maintains the sliding surfaces at a high temperature thus preventing solidification of any melt that does penetrate between the sliding surfaces.

Abstract: COMPOUND INTERNAL COMBUSTION ENGINE       AND METHOD FOR ITS USE            Abstract of the Disclosure A compound internal combustion engine having an efficiency materially higher than that of an engine operating on the conventional Otto or Diesel cycle. This is accomplished by using the heat of the exhaust gases to compress air, with or without the addition of fuel, which is then injected into the cylinder or cylinders of the engine just prior to ignition. In this manner, less heat is rejected from the overall cycle with improved efficiency.  In the preferred embodiment of the invention, a portion of the unused heat energy in the exhaust gases is used in a unidirectional energy converter to compress air or an air/fuel mixture which is then injected into the cylinders of the engine. The engine, whether it should operate on the Otto or Diesel cycle, does not compress gas on the upstroke of the piston until the compressed gas from the unidirec-tional energy converter is injected into the cylinder.
