A handheld aerosol-generating device may include an emitter configured to emit light, a sensor configured to receive light, and an aerosol chamber configured to hold an aerosol. The emitter may emit light into the aerosol chamber. The sensor may receive light from the aerosol chamber and measure at least one wavelength of the spectrum of the received light. Direct measurement of parameters, and/or the presence, of the aerosol in the aerosol chamber may be enabled, where the direct measurement of parameters of the aerosol in the aerosol chamber may enable optimal operation of an aerosol-generating system that may be the handheld aerosol-generating device.

A gas delivery device configured to be inserted into a structure. The gas delivery device also being configured to be attached to a vehicle. The gas delivery device including a housing and a canister rack disposed within the housing. The canister rack being configured to hold two or more chemical agent canisters. A gas delivery apparatus including a gas delivery device and triggering device is also disclosed.

An aerosol dispenser, outer container for an aerosol dispenser and a preform for an outer container, each include an open neck at the top and a closed end bottom. The open neck may include a first surface having a first surface diameter, a second surface disposed interior to the first surface and having a second surface diameter less than the first surface diameter, and a transition distinguishing the first surface from the second surface. For a dispenser and a container, a product delivery device may be disposed on the second surface and not interfere with a valve operable by a user when the valve is attached to the open neck in engagement with the first surface. At least one of the first and the second surfaces may be a sealing surface to prevent escape of propellant from the outer container to ambient when a valve is attached.

A Propellant-Free continuous dispenser for dispensing liquid or viscous materials under pressure. The container comprises a tension surface, and a bag containing the liquid to be dispensed, which is in contact with the tension surface. An actuatable valve to which the bag is open serves to controllably release the liquid from the bag, and a diaphragm forms a floor to the tension surface underneath the bag. The diaphragm is elasticated and presses the bag against the tension surface to flatten the bag, thus to expel the contents under pressure.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

A real-time measurement and marking apparatus is provided. The disclosure providing a portable marking device comprising: a housing including a main housing structure and a can cover, the main housing structure having a front open end, a rear nozzle end, a top surface, a bottom surface, and a pair of opposing side walls, wherein at least one of the side walls defines an aperture, the can cover having a rear open end, a front closed end, the can cover extending at the rear open end to selectively engage with the aperture defined by at least one of the side walls releasably securing a spray can within the housing; a nozzle member positioned at the rear nozzle end of the of the main housing structure; an optical measuring apparatus for real-time measuring of a distance between a point of focus and the portable marking device activated by one or more buttons.

A plural preform assembly including an outer preform and an inner preform. The outer preform includes an outer preform open end, an outer preform closed end longitudinally opposed thereto, and an outer preform sidewall joining the outer preform open end and the outer preform closed end. The inner preform may be disposed in the outer preform. The inner preform includes an inner preform open end, an inner preform closed end longitudinally opposed thereto, and an inner preform sidewall joining the inner preform open end and the inner preform closed end. The inner preform has an inner preform intrinsic viscosity and the outer preform has an outer preform intrinsic viscosity. The inner preform intrinsic viscosity and the outer preform intrinsic viscosity are different. The plural preform assembly may be blow molded into an article.

Multi-chamber applicator (1) comprising a multi-chamber container (2) for storing at least two subcomponents, said chamber comprising a device (3) for removing a mixture of the subcomponents.

A theft deterrent device includes a locking portion and a housing portion. The locking portion includes a locking mechanism. The housing portion includes a housing portion wall. The housing portion wall comprises a first material and is configured to house a second material within the housing portion wall. The second material is made of a different material than the first material. The second material is selected such that a cutting tool will be hindered when trying to cut through the housing portion.
