The manifold design provides for elongated filter and, temperature controlled cartridge heater insertion. There is further provided in a preferred embodiment a readily releasable electric source feed line plug connection at the butt end of the dispenser. The dispenser is well suited for the dispensing of methane foam as in a product packaging setting.

The first controller is disposed such that a user of the proper grip controller can manipulate the joystick with a thumb while properly holding the proper grip controller.

Abstract: Data is encrypted onto an electromagnetic beam by providing an electromagnetic beam having a signal component having a modal state, wherein the signal component is susceptible to accumulation of a geometric phase, and a reference component, transmitted along a path over at least part of which the signal component accumulates a geometric phase by transformation of its modal state from a first to a second modal state, from the second to at least one further modal state, and then back to the first modal state; and modulating with the data the geometric phase so accumulated, by modulating the modal state transformations. Data is decrypted from a received electromagnetic beam by corresponding processing of the received electromagnetic beam and by comparing an overall phase of the signal component with an overall phase of the reference component so as to retrieve the modulation.

Abstract: A sealer to bond film having a high temperature resistance (e.g., ceramic) substrate with properly sized groove receiving a heater element as in a flat faced wire band in a tight, flush to adjacent film presentation surface arrangement. A stacked ceramic plate set with wire band within a groove defined by an intermediate stack insert is a suitable substrate. The band is retained flush by a positioner securely locking down one end while the other end is provided at a housing body access location. The sealer is suited for use as a product-in-bag sealing device (products such as air, foam, foodstuff, etc.) with the heater element in contact with film to form a seal. A drag seal arrangement, where film layers are drawn past a fixed or adjustably mounted heater element is an example.

Abstract: An apparatus and method for providing a delay to an optical signal including a Latin router having a plurality of input ports, including at least one signal-input port, and a plurality of output ports, including at least one signal-output port, and a plurality of optical waveguides, each connecting one of the input ports to one of the output ports that is not a signal-output port, in which the plurality of waveguides are connected between the input ports and the output ports in an arrangement such that a first signal entering the device and mapped to any one of the output ports experiences a delay that is different from a delay that is experienced by a second signal entering the device and mapped to a different one of the output ports.

Abstract: A material spill prevention system with feed location sensing system to reduce the possibility of material spillage relative to the film being utilized for bag formation. The material spill prevention system monitors whether there is a proper film feed situation and, if not, precludes the release of material from the dispenser as in by precluding a flow controller opening and the release of material to the bag intended to receive the release chemical (e.g., a foam packaging bag). The prevention system is applicable to a variety of film feed arrangements as in a C-fold film drawn by a nip roller arrangement from a roll source with the dispenser mechanism positioned intermediate the nip and film source relative to film travel. An embodiment of the spill prevention system also features an absolute position transducer for monitoring position of a flow controller which controls output of material from the dispenser.
