Abstract: SINGLE POINT INTERMITTENT FLOW FUEL INJECTION            ABSTRACT OF THE DISCLOSURE UNDER RULE 72(b) A single point fuel injection system for an internal combustion engine including a throttle body having first and second air intake throats corresponding to first and second intake manifold planes of the engine, the air flow through each throat being controlled by throttle plates positioned within each throat.  The throttle body further includes a fuel accumulating bowl which is integrally formed with the throttle body, the bowl being enclosed by a diaphragm and cover member.  Within the enclosure of the fuel bowl are positioned a pair of injectors which are adapted to inject pulsed portions of fuel through a sonic nozzle and into the air intake throat of the throttle body.  The injection of pulses of fuel into the throat is timed in accordance with the sensing of the crankshaft reaching a position of 15° before top dead center to enhance the distribution of fuel charge from cylinder to cylinder.  The fuel  pressure within the bowl is controlled by a pressure regulator positioned within the enclosure formed by the bowl and housing cover, the diaphragm closing the bowl also forming the diaphragm for the regulator.  The pulses to the injectors are controlled by an electronic control unit in response to sensed engine conditions.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of indirectly connecting two parts, such as an acousto-optical building component composed of lead glass and a piezo electric transducer composed of lead-zirconium titanate, whereby at least one mono-molecular layer (having a maximum thick-ness of 100 nm) composed of a lead-free glass is directly applied under vacuum onto the surfaces of the parts to be joined and metal layers are then applied under vacuum onto such glass layer and/or the surfaces to be joined so that when the free surfaces of such free metal layers are brought into contact with one another under vacuum, a bond forms therebetween and such bonds indirectly connect the parts with one another.  The glass layer prevents diffusion of atoms or ions from the materials (such as lead) on either side of such layer so that the parts so-joined and/or the bonds so-formed are not impaired in any way.

Abstract: ABSTRACT       An electrical connector has a screw-clamping sleeve electrically connected to and aligned with a plug socket in an injection-moulded plastics housing. To prevent a conductor inserted in the clamping sleeve from entering the socket, the housing contains an integrally moulded partition which in the as-moulded state extends obliquely into the recess of the housing that will accommodate the clamping sleeve.    In this condition the socket can be inserted past the partition into a corresponding aperture, but the clamping sleeve when inserted bends the partition to a position between the clamping sleeve and the socket.

Abstract: ABSTRACT OF THE DISCLOSURE          A digital alarm system of the type having first and second electrically conductive loops connected by an alarm switch.  The alarm switch is normally open, but can be closed when an alarm state exists to elec-trically short one loop to the other.  Currents are gen-erated in each of the loops for use in detecting either the closing of the alarm switch or the occurrence of a fault in one of the loops.  Resistors are connected to each of the loops for use in detecting the presence or absence of the currents.  A first pair of transistor switches alternatingly short-circuit one resistor then the other; and a second pair of transistor switches, synchronized with the first pair, alternatingly short the ends of one loop then those of the other so that when the alarm switch is closed the first pair of transistor switches simultaneously short-circuit both resistors even if a fault occurs anywhere in one of the loops. Recording devices, such as flip-flops, coupled to the resistors, record signals indicative of a magnitude of the resistor voltage drops during intervals in which the resistors are not short-circuited.  Logic circuitry is then used to process this stored information to gener-ate signals indicating whether the alarm switch has been tripped or whether a fault has occurred.

Abstract: CONTOURED MOLDED PULP CONTAINER WITH POLYESTER LINER              ABSTRACT OF THE DISCLOSURE         An inexpensive, disposable, three-dimensionally contoured container, suitable for many purposes including holding food during exposure to high temperatures for long times in either a microwave or a conventional oven without any detrimental effect to the container or the food.  The container consists of an essentially impervious liner of polyethylene terephthalate directly bonded by its own sub-stance to a pre-formed contoured base obtained by molding to final shape nonbrowning substantially 100% bleached kraft wood pulp from an aqueous slurry thereof against an open-face suction mold, and drying the same under pressure imposed by a mating pair of heated dies.  The liner is formed by bonding to the pulp base a 0.5-2.0 mil thick film of thereoformable, substantially amorphous, substantially unoriented polyethylene terephthalate having a molecular weight which is understood to be in excess of 15,000.  The film is bonded to the base by pre-heating the base, rapidly pre-heating the film and then quickly pressing the film into contact with the base at a temperature in the range of 300-375°F, the pressing being done by vacuum in the range of about 20 inches of mercury applied through the base for no longer than about 1 second, and finally cooling so that the liner thereafter will not shrink-separate away from the contoured base as a result of subsequently exposing the container to a temperature of up to 400°F.

Abstract: Chevron Grooved Decoupling Obturator Abstract An obturator for a projectile (10) to be fired from a rifled barrel (12) is provided in accordance with this invention, with this obturator being mounted on the projectile in such a way as to permit rotational slippage. A preferred form of our obturator comprises a ring (16) of non-metallic material, which ring is capable of being mounted on a circular body portion (20) of the projectile.  An external portion of the obturator ring has a plurality of encircling slots (26), essentially parallel to each other, which slots are rearwardly in-clined so as to define a plurality of chevron-like members (28) designed to forcibly engage the rifling of the barrel.  The interior of the obturator ring is designed to slip rotationally with respect to the pro-jectile body portion as the projectile travels along the barrel, thereby advantageously minimizing the rotation of the projectile as a result of rifling effects.  One embodiment of an obturator (46) in accor-dance with this invention may be designed to disintegrate as it leaves the barrel, whereas another embodiment (16) may utilize an overwrap of high temperature fila-mentary material (36) in at least some of the slots, which overwrap serves to increase the hoop strength of the obturator.
