Abstract: Case 790111 CONTAINER FOR A MAINTENEANCE-FREE BATTERY            Abstract of the Disclosure A container for a maintenance-free lead-acid storage battery includes a multi-compartment base wherein individual cells of the battery are contained.  An over-lying cover in vapor-sealed engagement with the base includes a plurality of integrally-molded filler wells which extend from a recess in the top surface of the cover into respective cell compartments of the battery.  A one-piece molded vent cover seated within the recess includes a plurality of vent plug portions which extend through the filler wells into respective ones of the cell compart-ments.  An annular flange associated with each filler well coacts with ribs on the vent plug portions to lock the vent cover in place.  Escaping battery gas is conveyed from each of the cell compartments by axially-extending recesses on the vent plug portions, which form passageways from each cell compartment, and by ribs on the underside of the vent cover which space the vent cover from the battery cover to provide an additional passageway extend-ing to the escape gas gap through a peripheral gap formed between the vent cover and the side walls of the recess.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed herein is an internal combustion engine including a combustion chamber having an exhaust port which is periodically opened and closed, the exhaust port emitting exhaust containing a pressure wave when the exhaust port is opened, and a noise attenuating muffler connected to the exhaust port.  The muffler includes an exhaust conduit in communication with the exhaust port, the exhaust conduit being constructed to facilitate heating of the exhaust in the exhaust conduit and combustion of unburned hydrocarbons and carbon monoxide in the exhaust emitted from the exhaust port.  The exhaust conduit is also constructed to cause the pressure wave traveling in the exhaust conduit to return toward the exhaust port, as a pressure wave, and to afford arrival of the pressure wave at the exhaust port prior to the closing of the exhaust port.

Abstract: ABSTRACT OF THE DISCLOSURE A double cylinder circular knitting machine for forming articles of terry fabric, comprises, on one of the cylinders, a ring of arcuate terry sinkers each controlled by a butt so that it carries out a reciprocating an-gular sliding movement in an arcuate seat in the end of the cylinder, and a loop withdrawal ring for retaining the loop during the withdrawal of the end of the sinker from the loop.  The working end of the sinker is rotated be-fore its forward movement, so as to move it away from the loop withdrawal ring, and enables it to pass over the loop just formed on the previous row, the sinker then being rotated in the reverse direction for forming the next loop.  This arrangement permits loops to be formed in each row of the fabric.

Abstract: -10-               RCA 73, 815 ABSTRACT OF THE DISCLOSURE         An infrared remote control transmitter includes at least one infrared light-emitting diode poled with respect to a point of reference potential so as to be conductive in response to voltages having the opposite polarity of a DC supply voltage and to be nonconductive in response to voltages having the same polarity as the DC supply voltage. A push-pull amplifier is responsive to a pulse signal encoded to represent a remote control message to selectively couple the DC supply voltage or the reference potential to a capacitor coupled in series between the push-pull amplifier and the light-emitting diode.  The capacitor is charged and discharged  and an alternating drive voltage for the light-emitting diode having portions with polarities both the same as and opposite to the polarity of the DC supply voltage is generated.  The push-pull amplifier is arranged so that when a component failure occurs, the portions of the alternating drive voltage having the polarity opposite to the polarity of the DC supply voltage are at least inhibited to prevent the continuous (i.e., DC) emission of infrared radiation.

Abstract: TELEPHONE TRANSMITTER INCLUDING AN ELECTRET TRANSDUCER Abstract of the Disclosure A telephone transmitter including an electret transducer is connected to an electrical circuit mounted in the transmitter housing.  A resistor which can be of varying value is also connected to the circuit, the value of the resistor being adjusted to bring the operating characteristics within predetermined values.  This is done by applying a sound signal of known frequency to the transducer and measuring the output characteristics of the transducer.  This enables the suitable value of resistor to be connected into the circuit.  By this means variations arising from varying atmospheric conditions at assembly, and other causes, can be allowed for.  The metallized strip or film of the electret is preferably mounted with a very slight Vee shaped formation to avoid tight manufacturing tolerances which occur with a straight, or flat, strip.

Abstract: P.C. 6324 CANNULA WITH RADIOPAQUE TIP                        ABSTRACT A cannula for insertion into a body cavity, duct, or vessel of a patient includes a parent cannula member and an integral radiopaque tip.  The tip is configured so as to be distinguishable from internal body parts in an X ray or flouroscopic image, thus serving to precisely locate the position of the cannula within the patient without substantially obstructing the physician's view of such body parts.  The cannula tip and parent member are separately pre-formed from a non-toxic polymeric material and can be constructed so as to have different hardnesses.  In one embodiment, the tip is softer than the parent member in order to prevent internal injury to the patient, while in a second embodiment the tip is harder than the parent member for facilitating certain catheterization applications.  The pre-formed tip and parent member are then dielectrically heated and welded securely together to form a unitary, integral cannula.  The electrodes of the dielectric heating apparatus are connected to dies whose diametrical dimensions conform closely to those of the tip and parent member to provide the present cannula with completely smooth interior and exterior surfaces.  In order to prevent the burning of the cannula during this heating process, air is vented from the junction area by providing the outer die with a convex interior surface and by forming longitudinal grooves in the external surface of the inner die or mandrel.  The inner mandrel is formed by encapsulating the inner electrode with a highly insulative material to further inhibit burning of the cannula.
